The invention relates to a solar engineering and solar receiver designed for tracking the position of the sun. The object of the invention is to improve the accuracy of the orientation of the solar panels and more efficient use of the thermal radiation in the mechanism of a solar panel of the drive. For this purpose, a solar installation, comprising a solar panel, at least two telescopic thermo and reflective screen, provided with a rotation axis, on which is installed the solar panel is movable along an axis and articulated transmission mechanism, one of the links is connected with the axis, thermal actuators are fixed to solar panel parallel to its plane for engaging with another gear element and the screen is placed between the thermal actuators.
DESCRIPTION OF THE INVENTION
The invention relates to a solar engineering and solar receiver designed for tracking the position of the sun.
Known solar installation comprising a solar panel mounted on the rotational axis (see. AS USSR N 1760260, cl. The F 24 J 2/18. Solar thermal system, 1992).
The mechanism for tracking the position of the sun in this setting is made in the form of a hydraulic speed controller, ie, It is essentially a clockwork mechanism. This design is simple, but the complexity and the complexity of its maintenance associated with the need to lift weights daily and setting up the hydraulic control on the panel rotation speed limit its use of solar, solar thermal system.
Known solar installation comprising a solar panel, two telescopic and thermo reflective screen (see. Patent RF N 2028558, cl. The F 24 J 2/39. The solar installation, 1995).
The advantage of the known solar installation is the ease of maintenance, as Telescopic thermostats, fluid-filled with a high coefficient of volume expansion when heated by solar radiation will automatically orient the solar panel perpendicular to the solar radiation.
However, the known solar installation has a low accuracy of the orientation of the panel and inefficiently uses thermal energy from the sun. A first drawback stems from the fact that the angle of the solar panel rotation determined by the degree of heating of the thermo-actuator, which at this time falls solar radiation and therefore depends on the intensity of solar radiation and the angle of its incidence on svetovosprinimayuschuyu surface of the thermo-actuator, and the parameters of the thermo-actuator. A second drawback stems from the fact that the sun most of the time of day is directed at an acute angle to the surface of the thermo svetovosprinimayuschey therefore necessary to increase the volume of the working fluid and, consequently, the design dimensions for obtaining the desired characteristics of the thermo-actuator.
The invention aims to improve the accuracy of the solar panel orientation and more efficient use of radiant heat.
This object is achieved by the fact that in the known solar installation having a solar panel, two telescopic thermo and thermo-screen introduced axis on which is installed the solar panel with the possibility of rotation and longitudinal movement relative to the axis, and a two-tier transmission mechanism, one of the units which is connected to axis thermal actuators fastened to the solar panel parallel to its plane for engaging with another gear element and the screen is placed between the thermal actuators.

FIG. 1 is a perspective view of a solar installation.
FIG. 2 - a section along A-A in FIG. 1 (solar panel conventionally not shown).
Solar installation comprises a base 1 with the fixed rotation axis 2, which is installed solar panel 3 with possibility of rotation and longitudinal movement relative to the axis 2, a two-tier transmission mechanism formed by a pair of bevel gears 4 and 5, two thermo-actuator 6 and 7 and the screen 8. thermal actuators 6 and 7 are fixed to the solar panel 3 parallel to its plane, and the screen 8 is disposed therebetween. Gear 4 coupled to axle 2 and the gear 5 is mounted on the hub 9 and includes two stops 10 and 11 cooperating with the thermal actuators 6 and 7. The sleeve 9 is designed to transmit the rotation from the gear to the solar panel 3. The panel 3 is urged axially by a spring 2 12.
INSTALLATION WORKS AS FOLLOWS
In the initial position the rotation axis set perpendicular to two of the ecliptic plane, and the plane of the solar panel 3 in a direction to the south. When the solar panel 3 light side lighting in the morning or in the evening rays of the sun fall on the light-absorbing surface of one of the thermal actuators, eg thermal actuator 6. The other 7 at the same time is the screen 8 without undergoing solar radiation. Because this occurs when the temperature difference on the surfaces of the thermal actuators 6 and 7 occurs thermo extension rod 6 to a greater extent than the thermo-actuator 7. The rods 6 and 7 are thermal actuators, acting on the supports 10 and 11, the gear 5 is rotated clockwise. Gear 5, is rolled around a pinion 4 rotates through the sleeve 9 solar panel 3 together with the fixed thereto thermal actuators 6 and 7 and the screen 8 in the direction of the sun as long as no start illuminated sun thermo-actuator 7 and the thermo-actuator 6 starts shaded screen 8. In this position the solar panel 3 stops, as will be further increase of the temperature difference thermal actuators 6 and 7. Daily and seasonal fluctuations in air temperature compensated longitudinal movement along the axis of the solar panel 2, without causing its rotation. The accuracy of the solar panel orientation of the proposed device is higher than that of the prototype. This is because the thermal actuators positioned directly on the vibrating panels and solar irradiation is determined from the character width of the screen and its orientation relative to the sun, and therefore the orientation in which the screen panel is installed. In addition, the proposed device more effectively use the thermal energy of the sun, because the thermal actuators axis regardless of the orientation of the solar panels is constantly directed perpendicular to the solar wind, which also improves the accuracy of orientation.
CLAIM
Solar unit comprising a solar panel, two telescopic thermo and reflective display, wherein the solar installation includes a rotation axis, on which is installed the solar panel to rotate and move axially, and a two-tier transmission mechanism, one of the links is connected with the axis, thermal actuators fastened to the solar panel parallel to its plane for engaging with another gear element and the screen is placed between the thermal actuators.
