DEVICE FOR SUPPORTING UNIT pyramidal wind turbine

DEVICE FOR SUPPORTING UNIT pyramidal wind turbine

Name of the inventor: Stepanchuk Arkady Nikolaevich
The name of the patentee: Stepanchuk Arkady Nikolaevich
Address for correspondence: 85485, Donetsk region, Ukrainian, Str.. October, 2-A, A.N.Stepanchuku
Starting date of the patent: 2003.10.28

The invention relates to wind energy, namely the pyramidal structures windmills. The technical result consists in improving the efficiency, reliability, and economic efficiency and safety of operation is ensured by the fact that the support assembly device for pyramidal wind turbine comprising a blade in the form of pyramids uniformly fixed on the axle according to the invention further comprises a console uniformly fixed to the support shaft by means of axial and radial-thrust bearings on a common axis, and the outer edge of the console serve as a support for the lower tiers of the pyramid.

DESCRIPTION OF THE INVENTION

The invention relates to wind energy, namely the pyramidal structures windmills.

Known reference node device for pyramidal wind turbine comprising a blade in the form of pyramids uniformly fixed on the axis (see., Eg, FR 2418996 A, cl. The F 03 D 3/00, 02.11.1979), the essential features adopted for the closest analogue of the invention (prototype).

The disadvantages of the known device include low efficiency (efficiency) of the device, and reliability and manufacturability.

The technical result consists in increasing the coefficient of performance (COP) device, and the reliability and economic efficiency and safety of operation pyramidal wind turbine (LDPE), provided by the fact that the support assembly device for pyramidal wind turbine comprising a blade in the form of pyramids uniformly fixed on the axle according to the invention further includes console uniformly attached to the support shaft by means of axial and radial-thrust bearings on the common axis, and the outer edges of the brackets serve as support for the bottom tier of the pyramids.

DEVICE FOR SUPPORTING UNIT pyramidal wind turbine

1 shows a pyramidal wind turbine (LDPE), general view;

Figure 2 shows part of the console support assembly of pyramidal wind turbine (LDPE);

Figure 3 shows a view A-A of Figure 2.

Support assembly for a wind turbine pyramidal (LDPE) consists of a bearing unit 1 and the cantilever portion 2. The bearing unit 1 includes a vertical support shaft 3, the bearings 4 and 5, the sealing parts 6, 7. The support shaft body 3 rests on a thrust roller bearing 5 and the angular contact roller bearing 4. The first is to accept the vertical axial load operating LDPE, and the second - preferably horizontal side. 1 is shown by arrows.

Industry produces these bearings in a sufficient range. They can be selected depending on the desired capacity and installation in view of its operating mode. At recess the support shaft 3 and the bearing seats 4, 5, 7 in the housing is required to carry out turning and milling work.

The cantilever portion 2 consists of a disc 8 and 9, three cantilevered truss, which rely on their outer edges 10 LDPE three blades 13. As the disk drive wheel 8, a car or truck may be used (depending on the power setting). By the shaft 3 bolted disc 8, to which brackets 11 through 120 ° from each other are attached (and bolts) three console 9. At their ends mounted spring suspension mechanism 12, on which the three supporting arms 10 LDPE 12.

The literature is well represented by a strong design cantilever trusses, given their calculations. For our purposes, the most suitable design of spatial farm having dvuhraskosnye sides 14 in conjunction with the racks 15, which are able to withstand heavy loads are working on LDPE (1). A top and bottom may be made in the conventional embodiment, in conjunction transverse truss 16 and elements 17 (Figure 2). Three arms are made of angle steel. These elements must be fastened together in combination: a by welding and rivets or bolts, nuts, which are welded, so that they are not unwound during the movement of LDPE in the air flow turbulent.

Smooth, stable motion LDPE during wind gusts should be provided through the mechanism of spring suspension, consisting of elastic elements (springs) 18 and dampers (shock absorbers) 19.

must be mounted and a flexible hinge 21, for example, the cardan In the upper part of the PST 13 between its bearing block 20 and the upper tier.

The housing 7 of the bearing unit 1 is mounted on an I-beam and channel bars or, if necessary, additional counters raskreplyaetsya bottom depending on the weight of the blade and the shaft (axis) LDPE.

Upper bearing block JHA provides angular contact roller bearing 20, ie, about the same as the bearing 4 in the lower unit 1.

The gap between the console 2 and the bottom part of the PST has to be such that in the case of repair work, say, replacement of bearings 4 and 5, it is convenient to reach them.

Alignment, fitting and assembly of the installation of metal structures must be carried out at the bottom of the rack, and then they completely lifted and set on a foundation with a crane.

CLAIM

Device support assembly for pyramidal wind turbine comprising a blade in the form of pyramids uniformly fixed on the axis, characterized in that it further comprises a console uniformly attached to the support shaft by means of axial and radial-thrust bearings on the common axis, and the outer edges of the brackets serve as support for lower-tier pyramid.
