Description

The invention relates to solar technology, in particular to devices for fastening heliostat facets.

A device for fastening the heliostat facets is known, which contains channel bars mounted on the heliostat frame, each of which is equipped with a pin with a fixed platform fixed thereto for two adjacent facets and the latter clamping and including a nut fixing unit worn on a pin L1,

However, with this device, the heliostat assembly process is relatively complicated and lengthy, the alignment process is made difficult by the fact that the heliostat facet is impossible to carry out from the front side, the necessity of unlocking and locking the fixing unit, which leads to a relative alignment duration.

The aim of the invention is to accelerate the process of assembling and adjusting the heliostat facet and improving the manufacturability of the device.

The goal is achieved by the fact that in the device for fastening the facet of the hetiostat, which contains channel bars mounted on the heliostat frame, each of which is equipped with a stud with a supporting platform fixed on it for two adjacent facets and the clamping of the latter and including a nut fastening assembly worn on the hairpin, the support pad is made in the form of a bracket, the upper section of the shelf of which has two bent sections, both shelves are made with central openings, the opening of the lower shelf is filled open and its edge enters an annular groove made on the stud; the fastening assembly is made integral with the nut in the form of a split bracket, one section of which is further bent to interact with the channel and the other section has a central hole through which the stud passes.

In addition, the bent sections of the upper flange of the bracket can be made C-shaped to press the facet.

Figure 1 shows the structure of the device for fastening the heliostat facets, a partial section; 2 is the same side view; FIG. 3 is an embodiment of the structure of the device for fastening the heliostat facets; figure 4 is the same, side view.

The device for fastening the facet 1 (Fig. 1) of the heliostat 2 contains channel bars 3 installed on a frame (not shown) of the heliostat 2, each of which is equipped with a stud 4 with a supporting platform 5 fixed on it

for two adjacent facets 1 and the clamp 6 of the latter and including the nut 7 fastening unit 8, worn on the stud 4.

Support pad 5 is made in

5 in the form of a bracket 9, the upper section of which the shelf 10 has two bent sections 11 (Fig. 2), both shelves 10 and 12, respectively, are provided with central openings 13 and 14

Q (figure 1), and the hole 13 nizhneG: the shelf 12 is made open and its edge (not shown) is included in the annular groove 15, made on the stud 4, the mounting node 8

5 is integral with the nut 7 in the form of a split bracket 16, one section 17 of which is additionally bent to interact with the channel 3, the other section 18 has a central

 hole 19, through which the stud 4 (figure 2). The bent sections 11 (FIG. 3) of the upper flange 10 of the bracket 9 are made. A C-shaped for clamping the facet 1.

The edge of the hole 13 (figure 1) and the annular groove 15 ensure the fixing of the supporting platform 5 in the form of a bracket 9 on the stud 4. The bottom shelf 12 of the bracket 9 (figures 1 and 2) may have a shank 20 formed by an additional notch of the shelf 12 and bending the notched strips parallel to shelf 12. In shank 20, there is an open hole, similar to hole 13, and pin 4 has an additional groove, which can be combined with groove 15. Curved sections 11 serve as face stops of facet 1. From above, facets 1 are pressed to shelf 10 with

clamps 21 with screws 22.

In the embodiment of the device, the folded sections 11 (Figs. 3 and 4) simultaneously serve as the end stops and the clamps of the facet 1.

The region 18 (Figures 1 and 2) with the central opening 19 of the bracket 16 serves as an additional guide for the stud 4.

31

Section 17 of the fastening assembly 8 performs the role of a clamp and eliminates the passage of the fastening assembly 8 during the alignment process. An additional stop 23 (FIGS. 3 and 4) may be provided in contact with the channel 3 and formed by an additional notch of the bracket 16, which also protects the fixing unit 8 from turning. Brackets 9 and 16 can be made by stamping from sheet material, and stud 4 - by knurling from a bar.

The device for fastening the facet 1 Heliostat 2 works as follows.

When assembling the facet 1 (Figures 1 and 2) of the heliostat 2, the studs 4 are mounted in the holes of the channels 3, screw them into the nuts 7 of the fixing assemblies 8, previously put on the channels 3.

After that, the bracket 9 (support pad 5) is mounted on the stud 4, slightly tilting its lower shelf 12 and passing the upper end of the stud 4 through the opening 14 of the shelf 10 and then inserting the lower shelf 12 and the shank 20 into the groove 15 of the stud 4, then supporting pad 5 is fixed on the pin 4.

At the end of the mounting of the support sites 5 of the mount portion of the facets 1, for which each facet 1 is installed between the bent sections 11, which serve as stops of two adjacent reference

04

pads 5, and pressed against the last crinkles 21 with screws 22. In another embodiment of the device, the edges of each of the facets 1 (FIGS. 3 and 4) are pushed into the sheds of the C-shaped bent sections 11 of two adjacent reference sites 5. The facets 1, interact with their the ends with the bends of the C-shaped bent sections 11 are fixed in a predetermined position by them and pressed against the supporting platforms 5. After that, having rotated the studs 4, they axially move, the facet 1 can be adjusted. The rotation of the studs 4 can be performed both from the front and from the back side Kala heliostat 2.

The implementation of reference sites 5 in

in the form of staples 9, fixed on the studs 4 by the edges of the openings 13 in the annular grooves 15 and holding the facets 1 by the bent sections 11, in combination with

fasteners 8 in the form of staples 16, along with nuts 7, provides an easy assembly of facet 1, automatic selection of gaps in the joint without additional measures of locking, improved manufacturability and possibility of adjustment from the side of facet 1, which in turn speeds up the alignment process, facilitates assembly and improves manufacturability

heliostat.
