The invention relates to the field of construction, in particular to devices for removing ice from eaves of roofs. The technical result of the invention is to increase the effectiveness of the anti-icing control of roof eaves. The device for removing ice from the eaves of the roofs of buildings and structures is equipped with spring-loaded in the opposite direction the action of mechanical impulses by rods on the one hand connected with an elastic element made in the form of a linear waveguide mechanically decoupled from the roof eaves and on the other hand with a source of mechanical impulses, Installed on the fastening unit. The introduction of spring-loaded rods made it possible to concentrate the pulse of force from the source of its perturbation to the linear waveguide, thereby increasing the initial amplitude of the power disturbance in it, and the decoupling of this waveguide from the roof cornice makes it possible to propagate the forced elastic oscillations from this force perturbation along the linear waveguide to a longer length than Known device.
DESCRIPTION OF THE INVENTION
The invention relates to the field of engineering, which facilitates the removal of ice or icicles from roof cornices of various buildings and structures. This area can be extended to use this invention to remove ice from planes and aircraft elements that are exposed to this phenomenon during flight, antenna devices and other similar devices prone to icing.
A device for removing ice from the roofs of buildings and structures is known, including a movable rigid element along the eaves for striking ice [1].
A disadvantage of the known device is the low efficiency of the device due to the icing of the device itself for moving the rigid element along the eaves, and, in addition, its use for high-rise buildings is virtually impossible.
The closest in technical essence is the device for removing ice from the roofs of buildings and structures, including a source of mechanical impulses with a node of its attachment to a building or structure, and an elastic element located along the roof cornice, connected with a source of mechanical impulses [2].
The reason preventing the obtaining of the required technical result is the low effectiveness of the action of the elastic element on the ice due to the rigid attachment of the latter to the cornice, as a result of which the excited oscillations in the elastic element are damped in the nearest zone of action of the source of mechanical impulses. In addition, the design of the attachment unit installed on the roof cornice also damages the mechanical impulses from the source, which further reduces the efficiency of removing ice.
The invention is based on the task of achieving a technical result by increasing the efficiency of the device for removing ice from the roofs of buildings and structures, which is solved by inserting spring-loaded in the opposite direction the action of mechanical impulses by rods on the one hand connected with an elastic element made in the form of a linear waveguide, Mechanically decoupled from the roof cornice, and on the other hand - a source of mechanical impulses, mounted on the attachment unit.
The introduction of spring-loaded rods made it possible to concentrate the pulse of force from the source of its perturbation on the linear waveguide, thereby increasing the initial amplitude of the power disturbance in it, and the decoupling of this waveguide from the roof eave allows the forced elastic vibrations from this force perturbation along the linear waveguide to travel much longer than Known device [2].
In addition, the linear waveguide is made in the form of any metal profile, the cross-section of which provides rigidity according to the allowable deflection on the length between the attachments of two adjacent rods under an ice-loaded condition.
This structural feature of the linear waveguide makes it possible to ensure a stable propagation of elastic vibrations to the calculated length of this waveguide.
Moreover, the value of the clearance of the mechanical decoupling between the roof cornice and the elastic element should be more than the amplitude of the excited oscillations of the linear waveguide from the source of mechanical pulses, and this waveguide should be located in the zone of intense ice formation at the edge of the cornice.
The size of the clearance gap and the location of the linear waveguide at the edge of the cornice allows the liquidation of ice, for example, in the form of icicles, near the root of their formation, while eliminating the danger of contact between the oscillating surface of the waveguide and the cornice.
It is quite reasonable that the fastening unit is installed on the wall of a building or structure from the outside or inside.
This installation of the mounting unit increases the rigidity of the entire system in the direction of recoil at mechanical pulses, thereby increasing the amplitude of the effect on the linear waveguide.
And it is reasonable that the attachment unit is in the form of a tube coaxial to the rod rigidly fixed in the wall of the building and provided on the opposite side with the attachment of the linear waveguide cavity for installing a source of mechanical impulses between the spring-loaded stem and the stop attached to the pipe.
Such a technical solution will increase the comfort of maintenance, and it becomes possible to reset the sources of pulses from one cavity to another, thereby significantly increasing the length of the cornice to be processed from one device. In addition, it becomes possible to process a variety of buildings and structures from one device.
Another technical solution is that the source of the mechanical pulses is made in the form of a flat coil of eddy currents and is equipped with a pulse current generator electrically connected to the coil, and a plate made of high conductivity material is additionally installed between the coil and the rod.
Such execution of a source of mechanical impulses will allow producing mechanical pulses with a duration of about a dozen parts to several microseconds, which, at low energy costs for pulse production, will allow to develop a large impact power along a linear waveguide.
Finally, an additional eddy current coil is electrically connected between the coil of eddy currents and the rod, electrically connected to the first coil.
This technical solution will increase the efficiency of the transition of electromagnetic processes into mechanical energy.
Ultimately, the technical result of implementing the proposed invention in comparison with the prototype will significantly increase the overall efficiency of the device as a whole, directly related to increasing the efficiency of removing ice from the cornices. Moreover, the device can operate from various types of sources of mechanical impulses, including magnetic pulse systems, electromagnets, vibrators, mechanical, pneumatic, powder and other types of accumulators, and even the use of manual mechanical shocks is possible. Of course, in each individual case, the economic feasibility, efficiency and productivity of stripping roof cornices from ice should be compared.
In Fig. 1 is a longitudinal sectional view of a device for removing ice from the roof cornices of buildings and structures in the design of an attachment unit from the inner (attic) side of the wall.
In Fig. 2 - the same in the performance of the installation of the fastening unit from the outside of the wall.
In Fig. 3 is a view A of FIG. 1 and Fig. 2 .
The device for removing ice from the roofs of buildings and structures contains a source of mechanical impulses 1 connected via cable 2 to power supply 3 and installed in the cavity 4 of the attachment 5 which is rigidly fixed to the wall 6 of the building or structure, an elastic element made in the form of a linear A waveguide 7 disposed along the roof eave 8 and a rods 9 that have springs 10 urging these rods through the plate 11 to the source of mechanical pulses 1. The rods 9 at the other end are rigidly or hingedly connected to a linear waveguide 7 made in the form of any metallic Profile, as, for example, in FIG. 1 in the form of a corner, and in FIG. 2 - pipes, but with the condition of stiffness in the permissible deflection at the length l 1 and l 2 between the fasteners of two adjacent rods 9, the waveguide 7 being mechanically decoupled from the roof cornice through the gap 
, Equal to a certain magnitude larger than the amplitude of the excited oscillations and at the same time is located in the zone of intense ice formation 12. The fastening unit 5 is rigidly mounted by means of pins 13 on the wall of the building 6 with the outer side (Figure 1) or the inner side (Figure 2) , And furthermore is provided with a pipe 14 in which the rod 9 is displaceable, and the pipe itself is fixed either inside the wall, on the outside, by means of a flange 15, and from the inside by a fastening device 5.
In addition, the power supply 3 can be implemented as a pulse current generator, the source of the mechanical pulses 1 is a planar coil of eddy currents, and the plate 11 is made of an electrically conductive material or in the form of a second planar coil electrically connected to the first.
When the critical icing value is reached, which is set for each individual case, the power supply 3 is turned on, and if it is made in the form of a pulse current generator, then it accumulates electrical energy and when it reaches a predetermined level it is fed through a cable 2 to a source in a short period of time Mechanical impulses in the form of an eddy current coil in which electrical energy is converted into a magnetic field interacting with a plate 11 having a high electrical conductivity or with a second coil, for example connected in series to the first coil, and as a result, the plate or additional coil 11 Source of mechanical impulses (main coil) 1. In turn, the plate or additional coil drives the spring-loaded rod 9, which strikes the linear waveguide 7, exciting the forced elastic vibrations in the last element. These oscillations, spreading over the entire length of the waveguide, shake off the ice both from the waveguide itself and from the eaves of the roof 8. After performing the useful work, the rod 9 returns to its original position due to the spring 10.
