DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the following is a brief introduction to the drawings required for use in the embodiments or the prior art descriptions. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. The content of the utility model is further described below in conjunction with the drawings:

[0021] Example 1

[0022] Refer to the instruction manual Figure 1 , 2 A heliostat support assembly includes a mirror support 1, a screw rod 2, a screw sleeve 3 and a nut 4.

[0023] Refer to the instruction manual Figure 3 The mirror holder 1 includes a connecting plate 11 and a connecting seat 12 fixed to the bottom surface of the connecting plate 11. A second screw hole 13 is opened in the center of the connecting seat 12. The connecting plate 11 is fixedly connected to the bottom surface of the heliostat by gluing. The connecting plate 11 can be made of ceramic, steel, aluminum and other materials.

[0024] Refer to the instruction manual Figure 4 The screw rod 2 includes an upper screw rod 21, a lower screw rod 23 and a baffle plate 22 arranged between the upper screw rod 21 and the lower screw rod 23. The upper screw rod 21 is used to be threadedly connected with the second screw hole 13 to achieve a fixed connection between the mirror holder 1 and the screw rod 2. The baffle plate 22 is used to contact the connecting seat 12 when tightening the screw rod 2 so that the upper screw rod 21 and the second screw hole 13 are tightened.

[0025] In order to achieve pre-tightening of the screw rod 2 and the connecting seat 12, the screw rod 2 also includes a screw head 24 fixed to the bottom end of the lower screw rod 23, and the screw head 24 is used to fasten the lower screw rod 23 to the connecting seat 12;

[0026] The screw head 24 can be an external hexagonal screw head, an internal hexagonal screw head, a screw head with a cross groove, or a screw head with a slotted groove, etc. The screw 2 can be tightened and fixed by connecting a wrench, a screwdriver, or other tools to the screw head 24 .

[0027] Refer to the instruction manual Figure 5 The screw sleeve 3 includes a sleeve body 31 and a flange 32 arranged at one end of the sleeve body 31. A first screw hole 33 is opened axially along the sleeve body 31. The first screw hole 33 has an internal thread. The screw sleeve 3 is connected to the outside of the lower screw rod 23 through the internal thread. The outside of the sleeve body 31 has an external thread. The nut 4 is threadedly connected to the external thread on the outside of the sleeve body 31. The direction of the internal thread of the first screw hole 33 is opposite to the direction of the external thread of the sleeve body 31.

[0028] Since the upper screw rod 21 is only used to connect the connecting seat 12 and does not need to be adjusted in position, and the position of the screw sleeve 3 on the lower screw rod 23 may need to be adjusted according to the heliostat mirrors in different positions, the length of the upper screw rod 21 is set to be smaller than the length of the lower screw rod 23.

[0029] At the same time, the outer diameter of the screw head 24 is smaller than the outer diameter of the lower screw 23 , which can facilitate the sleeve 31 to be smoothly inserted from the bottom end of the screw 2 .

[0030] In a specific embodiment, the thread direction of the outer part of the upper screw 21 is opposite to the thread direction of the outer part of the lower screw 23, and the thread direction of the first screw hole 33 is opposite to the thread direction of the outer part of the sleeve 31; when the nut 4 is tightened toward the mirror support 1, the screw 2 is tightened in the same direction, and the upper screw 21 will not be loosened from the connecting seat 12. At the same time, the screw sleeve 3 and the nut 4 move toward each other to clamp the truss.

[0031] The method for using the heliostat support assembly in the utility model is as follows: first, the connecting plate 11 of the mirror support 1 is fixedly connected to the back of the heliostat mirror by gluing, the upper screw 21 of the screw 2 is threadedly connected to the connecting seat 12, and the screw 2 is tightened through the screw head 24, and then the screw sleeve 3 is threadedly connected to the lower screw 23, with the flange 32 facing the mirror support 1, the sleeve body 31 of the screw sleeve 3 is passed through the through hole opened on the truss, and the nut 4 is threadedly connected to the sleeve body 31 from the bottom of the lower screw 23. The state at this time is as shown in the attached figure. Figure 6 As shown, after the heliostat and the truss are positioned, it is only necessary to tighten the nut 4 using a wrench or other tool, the screw sleeve 3 and the nut 4 move toward each other, and the truss is clamped between the flange 32 and the nut 4, thereby achieving the support and fixed connection between the heliostat and the truss; since the nut 4 is located outside the truss and not between the heliostat and the truss, it will not be affected by the insufficient operating space between the heliostat and the truss, making the installation and adjustment of the support assembly as a whole convenient and efficient.

[0034] Obviously, modifications and / or additions of components can be made to the above-described heliostat support assembly and the corresponding method without departing from the field and scope of the present invention.

[0035] It is also clear that although the utility model has described the heliostat support assembly in detail, those skilled in the art will certainly be able to obtain many other equivalent forms of heliostat support assemblies and corresponding methods, which have the characteristics described in the claims and are therefore within the scope of the protection field defined thereby.
