[0041] In recent years, solar energy has attracted much attention as a clean energy source. The core principle of solar thermal power generation is to use heliostats to accurately reflect sunlight onto a heat absorption tower, generate high-temperature and high-pressure steam by heating the working fluid in the heat absorption tower, and finally use the steam to drive the steam turbine to generate electricity. In a tower solar thermal power plant, there are a large number of heliostats, so their structural stability plays a vital role in the reflection quality of sunlight.

[0042] In the prior art, a heliostat includes a mirror body and a bracket, wherein the mirror body is mounted on the bracket so that the mirror body reflects sunlight onto a heat absorbing tower, thereby realizing the utilization of solar energy.

[0043] However, the mirror bodies of heliostats vary in size and require the use of corresponding brackets for installation, which is inconvenient for the installation and use of the mirror bodies. As a result, the heliostat brackets require a lot of manpower and material resources during installation and are complicated to operate. In addition, the support structure of the heliostat cannot be adaptively adjusted according to the shape and size of the heliostat, and its application range is relatively narrow.

[0044] In order to solve the above problems, the present application provides a heliostat bracket and a heliostat. The heliostat bracket splices four right-angle rods to form a rectangular frame through the setting of a telescopic frame for installing a mirror body of the heliostat, and a connecting rod is slidably connected between adjacent right-angle rods, so that the distance between adjacent right-angle rods is adjusted by the connecting rod, thereby realizing the adjustment of the size of the rectangular frame, so that mirror bodies of different sizes can be installed in the rectangular frame without using a specific heliostat bracket, thereby improving the applicability of the device and facilitating the installation of the heliostat.

[0045] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0046] On the one hand, the present application provides a heliostat support, referring to Figures 1 to 4 The heliostat support includes a bottom support assembly 100 and at least one telescopic frame 200 .

[0047] The telescopic frame 200 includes four right-angle rods 210 and four connecting rods 220. The right-angle rods 210 are spliced ​​into a rectangular frame for installing the mirror body. The two ends of the connecting rods 220 are respectively slidably inserted into two adjacent right-angle rods 210 to adjust the distance between adjacent right-angle rods 210. The bottom support assembly 100 is connected to the right-angle rods 210.

[0048] Among them, refer to Figure 1 and Figure 3 The right-angle rod 210 is L-shaped, and four right-angle rods 210 form the four corners of the rectangular frame, and the sides of adjacent right-angle rods 210 are connected by connecting rods 220 to form a complete rectangular frame. The mirror body of the heliostat is installed on the right-angle rods 210 of the rectangular frame, and the size of the rectangular frame is adapted to the mirror body so that the rectangular frame just wraps the mirror body, and then the mirror body is fixed on the right-angle frame through a corresponding fixing device, thereby realizing the installation of the mirror body.

[0049] The fixing device can be a structure such as a bolt or a clip, or a mounting groove can be opened on the inner wall of the right-angle rod 210, and the edge of the mirror body can be inserted into the mounting groove, so that the mirror body can be fixed through the mounting grooves on the right-angle rod 210 around, making installation easier.

[0050] By adopting the above technical solution, when installing the mirror body, the distance between the four right-angle rods 210 is adjusted to adjust the length and width of the rectangular frame to adapt to the size of the mirror body. The mirror body is fixed on the rectangular frame formed by the right-angle rods 210, and the four right-angle rods 210 are connected to the mirror body, so that the right-angle rods 210 and the connecting rods 220 are fixed while the mirror body is fixed, and the relative sliding between the right-angle rods 210 and the connecting rods 220 is avoided. Therefore, there is no need to fix the right-angle rods 210 and the connecting rods 220 separately, which improves the efficiency of the heliostat installation; and in the process of large-scale installation of heliostats, there is no need to match the mirror body with the bracket, which reduces the steps of sorting and corresponding, and further improves the efficiency of assembly.

[0051] In some embodiments, reference Figure 1 and Figure 2 The bottom support assembly 100 includes a height adjustment member 110 and an angle adjustment member 120 , the angle adjustment member 120 is connected to the height adjustment member 110 to adjust the height of the angle adjustment member 120 , and the telescopic frame 200 is connected to the angle adjustment member 120 to adjust the angle of the telescopic frame 200 .

[0052] By adopting the above technical solution, the height adjustment member 110 can adjust the height of the angle adjustment member 120, thereby adjusting the height of the telescopic frame 200 on the angle adjustment member 120, so as to adjust the height of the heliostat body, so that the height of the heliostat can be lowered during installation to facilitate the installation of the body, and at the same time, the height adjustment can be used to control different heliostats to be at different height positions, thereby improving the reflection effect of the heliostat on sunlight. In addition, the angle of the telescopic frame 200 can be adjusted by the angle adjustment member 120, thereby adjusting the tilt angle of the body, so as to make the body at a suitable reflection angle to receive more correct light.

[0053] In some embodiments, the height adjustment member 110 includes a support pole 111 and a telescopic portion 112 , the support pole 111 is disposed on the telescopic portion 112 , the telescopic portion 112 drives the support pole 111 to slide in a vertical direction, and the angle adjustment member 120 is disposed on the top of the support pole 111 .

[0054] Exemplarily, the telescopic portion 112 is an electric telescopic rod, which is arranged in the vertical direction. The support pole 111 is fixed on the electric telescopic rod, so that the electric telescopic rod drives the support pole 111 to slide in the vertical direction, thereby adjusting the height of the telescopic frame 200.

[0055] In other implementations, the telescopic portion 112 may also be a hydraulic cylinder, a pneumatic cylinder or other device, as long as it can achieve the up and down movement of the supporting pole 111 , and no excessive restrictions are made herein.

[0056] In some embodiments, reference Figure 1 and Figure 2 The angle adjustment member 120 includes two telescopic diagonal rods 121 , one end of the telescopic diagonal rod 121 is hinged on the supporting vertical rod 111 , and the other end is hinged on the bottom of the right-angle rod 210 , and the two telescopic diagonal rods 121 are symmetrically arranged on both sides of the supporting vertical rod 111 .

[0057] Among them, the two telescopic diagonal rods 121 are both electric telescopic rods. The two telescopic diagonal rods 121 are symmetrically hinged to support the two sides of the vertical rod 111, and are respectively hinged to the right-angle rods 210 on both sides. The hinge axes of the two telescopic diagonal rods 121 are both in the horizontal direction and parallel to each other.

[0058] By adopting the above technical solution, the telescopic frame 200 is supported by two telescopic diagonal rods 121, thereby realizing the connection and fixation of the telescopic frame 200, and by adjusting the length of the two telescopic diagonal rods 121, the inclination angle of the telescopic frame 200 can be changed, thereby realizing the adjustment of the angle of the mirror body. During the adjustment process, only one side of the telescopic diagonal rod 121 needs to be extended or shortened to drive the telescopic frame 200 to rotate, so as to realize the adjustment of the inclination angle of the telescopic frame 200.

[0059] In other embodiments, the telescopic diagonal rod 121 may also be a hydraulic rod or a pneumatic push rod, as long as the telescopic diagonal rod 121 can be extended or retracted, and no excessive restrictions are made here.

[0060] In some embodiments, reference Figure 4 A slide groove 211 is provided on the right-angle rod 210 , and the connecting rod 220 is slidably inserted in the slide groove 211 .

[0061] The right angle bar 210 is formed by bending a channel steel at a right angle. Moreover, the chute 211 of the channel steel is a dovetail groove to limit the connecting rod 220 from sliding out of the side of the channel steel. The connecting rod 220 is adapted to the chute 211 to reduce the shaking of the connecting rod 220 after being connected to the right angle bar 210.

[0062] Furthermore, the connecting rod 220 can also be a channel steel or a hollow rod, thereby reducing the weight of the connecting rod 220, reducing the use of steel materials on the one hand, and reducing the weight of the entire bracket on the other hand, so as to facilitate the transportation and installation of the bracket.

[0063] In some embodiments, a limiting groove 212 is provided on the side wall of the slide groove 211 , and a limiting block 221 is provided at the end of the connecting rod 220 , and the limiting block 221 is slidably connected in the limiting groove 212 .

[0064] Among them, the limit groove 212 is opened along the length direction of the slide groove 211, and both ends of the limit groove 212 are sealed. The limit block 221 is slidably connected in the limit groove 212 along the length direction of the limit groove 212. When the end of the connecting rod 220 moves to the end of the right-angle rod 210, the limit block 221 abuts against the end seal of the limit groove 212, thereby limiting the continued sliding of the limit block 221, thereby realizing the limiting effect on the connecting rod 220.

[0065] In some embodiments, reference Figure 1 and Figure 3 , the number of telescopic frames 200 is 4. And, the four telescopic frames 200 are arranged in a field shape.

[0066] At this time, the two telescopic diagonal rods 121 are located in the middle of the four telescopic frames 200 spliced ​​into an integral structure, thereby realizing the connection of multiple telescopic frames 200, without the need to set up more bottom support assemblies 100. At this time, the four mirror bodies can be installed on the four telescopic frames 200 respectively. It is also possible to install a larger mirror body on the combination of four telescopic frames 200. The combination of four telescopic frames 200 is equivalent to setting a strong rib in the middle of the telescopic frame 200, and at the same time will not hinder the telescopic movement of the telescopic frame 200.

[0067] For example, multiple telescopic frames 200 can be arranged in a single row, double row, triple row, etc., without too much restriction. In this way, the bottom support assembly 100 can support multiple telescopic frames 200, reduce the number of bottom support assemblies 100, improve installation efficiency, and help reduce costs.

[0068] In some embodiments, connecting pieces for connecting the telescopic frames 200 are disposed between adjacent telescopic frames 200 .

[0069] For example, the connecting member may be a bolt, a buckle, etc. During the installation process, only two right-angle rods 210 of the telescopic frame 200 that abut against each other are fixed by bolts or buckles, etc., so as to realize the connection between multiple telescopic frames 200 without affecting the telescopic movement of the telescopic frame 200.

[0070] The heliostat support also includes a control system, which is used to control the movement of the telescopic inclined rod 121 and the telescopic part 112, so as to facilitate the adjustment of the angle and height of the mirror body. The control system is a remote control system, which is a prior art and will not be described in detail here.

[0071] On the other hand, the present application provides a heliostat, including a mirror body and a heliostat bracket, wherein the mirror body is mounted on the heliostat bracket.

[0072] The heliostat bracket in this embodiment has the same structure as the heliostat bracket provided in any of the above embodiments, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiments.

[0073] The heliostat provided by the present application, through the setting of the telescopic frame 200, splices four right-angle rods 210 to form a rectangular frame for installing the mirror body of the heliostat, and a connecting rod 220 is slidably connected between adjacent right-angle rods 210, so that the distance between adjacent right-angle rods 210 is adjusted by the connecting rod 220, thereby realizing the adjustment of the size of the rectangular frame, so that mirror bodies of different sizes can be installed in the rectangular frame without using a specific heliostat bracket, thereby improving the applicability of the device, facilitating the installation of the heliostat, and at the same time, the height and tilt angle of the mirror body can also be adjusted, further improving the reflective effect of the heliostat.
