Then people begin to pay attention to the development and utilization of renewable new energy, among which solar energy is particularly valued. As an inexhaustible new energy, solar energy has been widely used in people's lives, especially solar thermal power generation technology. At present, solar thermal power generation technology mainly includes: solar trough power generation, solar tower power generation, and solar butterfly power generation. As an important part of the solar tower power generation system, the performance of the heliostat directly affects the efficiency of tower solar power generation, and the mirror plate bracket as the basic part of the heliostat determines the performance of the heliostat. The existing heliostat mirror plates are mostly welded from steel materials. The steel will produce thermal deformation during galvanizing and welding, resulting in large overall structural errors and high overall costs; the mirror surface is mostly installed as a whole piece, which will form a large wind resistance, which is easy to cause the heliostat to swing and the reflected light wave to be unstable.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1 , 2, 3, and 4 show a heliostat mirror plate bracket, comprising a main beam 1, a sub-beam 2, a reflector bracket 3, and a reflector 4. Two main beams 1 are provided, the main beams 1 are separated and arranged in parallel, the sub-beams 2 are taken, and both ends thereof are vertically bonded to the upper surfaces of the two main beams 1 by using a polymer adhesive, and several required sub-beams 2 are evenly spaced and bonded according to the above steps. When bonding the sub-beams 2, the opening direction of the dovetail groove 5 on the sub-beam 2 is all toward one side; a dovetail groove 5 is provided on one side of the sub-beam 2, a dovetail 6 is provided on one side of the reflector bracket 3, and the reflector bracket 3 is provided with a dovetail 6. The dovetail 6 is aligned with the dovetail groove 5 of the subbeam 2 and inserted in sequence. After insertion, the reflector brackets 3 are evenly spaced apart. To ensure that the dovetail groove is firmly connected, the sizes of the dovetail 6 and the dovetail groove 5 match. After all the subbeams 2 are connected to the reflector brackets 3 in sequence, the reflector 4 is inserted into the mirror plate groove A7 of the subbeam 2 and the mirror plate groove B8 of the reflector bracket 3 from one side with the front side facing up, and then slowly pushed in. During the pushing process, it is important to pay attention to that one side of the reflector must be inserted into the mirror plate groove B of all the reflector brackets 3 in sequence. All reflectors 4 are inserted in sequence according to the above steps.

[0021] To ensure that the mirror plate is flat and firmly engaged, the mirror plate groove A and the mirror plate groove B have the same height and are in the same horizontal plane. To ensure that the reflector 4 can be firmly engaged in the mirror plate groove A7 and the mirror plate groove B8, the thickness of the reflector 4 matches the height of the mirror plate groove A7 and the mirror plate groove B8.

[0022] Since the reflector brackets 3 are spaced apart, after the reflector 4 is inserted, a pressure relief gap 9 is formed between one side of the reflector 4 and the auxiliary beam 2. The pressure relief gap 9 can effectively reduce the load impedance of the wind on the mirror surface, thereby improving the stability of the heliostat.

[0023] Since a reinforcing ring 10 is provided on the upper and lower surfaces inside the reflector bracket 3, the reinforcing ring 10 can improve the strength of the reflector bracket 3, making it have a stronger load resistance and more stable. In addition, the existence of the reinforcing ring 10 ensures the development of subsequent functions of the heliostat mirror plate bracket. The reinforcing ring 10 can be tapped without damaging the reflector bracket 3, and other components can be connected by thread.

[0024] In order to avoid thermal deformation caused by welding and hot-dip galvanizing, and thus ensure the accuracy of the heliostat, the main beam 1, the secondary beam 2, and the reflector bracket 3 are all made of aluminum alloy.

[0025] The working process of the present invention is as follows:

[0026] The two ends of the sub-beam 2 are respectively bonded vertically to the upper surfaces of the two main beams 1 by using a polymer adhesive, and the dovetail 6 of the reflector bracket 3 is aligned with the dovetail groove 5 of the sub-beam 2 and inserted in sequence. After the insertion, the reflector bracket 3 is evenly spaced apart, and the reflector 4 is inserted from one side into the mirror plate groove A7 of the sub-beam 2 and the mirror plate groove B8 of the reflector bracket 3 with the front side facing upward, so that the heliostat mirror plate bracket can be formed, and the heliostat mirror plate bracket is installed in the heliostat system; the heliostat system is provided with an azimuth adjustment mechanism and an altitude adjustment mechanism under the heliostat mirror plate bracket, and the heliostat system is controlled by a sensor as a whole, so that it can identify the position of the sun, and the heliostat mirror surface always moves in the direction of the sun. During the movement of the mirror plate, the pressure relief seam 9 can effectively reduce the wind resistance. When the mirror surface performs tracking movement at the speed of the diurnal movement, the sunlight is irradiated to the heliostat mirror surface and then reflected by the heliostat mirror surface to the absorption tower, and the absorption tower absorbs the reflected sunlight to form a complete set of solar thermal power supply system.
