[0021] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0022] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] See also Figure 1 This embodiment provides a heliostat support, including a base 1, an azimuth drive device 2, a connecting seat 3, a mirror frame 4 and an altitude drive device 5, wherein the azimuth drive device 2 is connected to the base 1 and the connecting seat 3, the mirror frame 4 is rotatably connected to the connecting seat 3, and at least one of the connecting seat 3 and the output end of the azimuth drive device 2 is connected to the mirror frame 4 through the altitude drive device 5. The azimuth drive device 2 is used to drive and adjust the azimuth of the connecting seat 3, and then drive and adjust the azimuth of the mirror frame 4; the altitude drive device 5 is used to drive and adjust the altitude of the mirror frame 4. The mirror frame 4 tracks the movement of the sun through the azimuth drive device 2 and the altitude drive device 5.

[0024] This embodiment also provides a heliostat, comprising the above-mentioned heliostat bracket and reflector group 10, wherein the reflector group 10 is mounted and fixed on the mirror frame 4. The mirror frame 4 tracks the movement of the sun through the azimuth angle driving device 2 and the altitude angle driving device 5, thereby driving the reflector group 10 to track the sun.

[0025] Heliostats will encounter strong winds in actual applications, and the area of ​​the reflector in the heliostat is very large, usually tens of square meters or even hundreds of square meters, and there is a gap at the connection between the mirror frame and the connecting seat. Therefore, it is very easy to be affected by wind and shake, causing the surface shape of the reflector to change, and it is impossible to accurately reflect sunlight to the target position, affecting the efficiency of tower solar thermal power generation, and even possible problems such as overheating and damage of the collector. In the related technology, the rigidity of the entire mirror frame is increased by increasing the outer diameter of the main beam, the cross-sectional size of the secondary beam, or adding transverse purlins to enhance the overall rigidity and stability of the heliostat. However, the stability of the heliostat under wind load is achieved by increasing the mechanical rigidity of the heliostat structure, which will lead to an increase in processing costs, and because it only changes the rigidity of the structure, the natural frequency of the structure changes, but under the excitation vibration of the wind load, the heliostat will still produce stimulated vibration, and the vibration of the heliostat under wind load cannot be fundamentally changed. To this end, as a key technology of this embodiment, the heliostat support further includes a damping device 6, and at least one of the connecting seat 3 and the output end of the azimuth driving device 2 is connected to the mirror frame 4 through the damping device 6. In this embodiment, the mirror frame 4 and the connecting seat 3 are connected through the damping device 6, or the mirror frame 4 and the output end of the azimuth driving device 2 are connected through the damping device 6, so that the energy of the wind-induced vibration of the heliostat can be quickly consumed under wind load, the stability of the heliostat mirror frame 4 under wind load is improved, and the heliostat always maintains stable operation, thereby reducing the influence of wind vibration on the focusing accuracy of the heliostat light spot.

[0026] In this embodiment, one end of the damping device 6 is rotatably connected to the mirror frame 4, and the other end is rotatably connected to at least one of the connecting seat 3 and the output end of the azimuth driving device 2. In some embodiments, one end of the damping device 6 is rotatably connected to the mirror frame 4, and the other end is rotatably connected to the connecting seat 3; in other embodiments, one end of the damping device 6 is rotatably connected to the mirror frame 4, and the other end is rotatably connected to the output end of the azimuth driving device 2; in this embodiment, the azimuth driving device 2 adopts a reduction device, such as a reducer, including a fixed shell fixedly connected to the base 1, a reduction mechanism located in the fixed shell, and an output end connected to the reduction mechanism, such as an output flange, the connecting seat 3 is connected and fixed to the output end of the azimuth driving device 2, such as the output flange, and the other end of the damping device 6 is rotatably connected to the output flange of the azimuth driving device 2. Of course, the other end of the damping device 6 can also be rotatably connected to both the connecting seat 3 and the output end of the azimuth driving device 2. In this embodiment, the rotation connection is a movable connection mode, such as a hinge.

[0027] In a specific embodiment, the damping device 6 includes a plurality of dampers 61, one end of each damper 61 is rotatably connected to the mirror frame 4, and the other end is rotatably connected to at least one of the connection seat 3 and the output end of the azimuth driving device 2. The mirror frame 4 includes a main beam 41, and the plurality of dampers 61 are distributed along the length direction of the main beam 41; the dampers 61 are arranged in pairs and are distributed on both sides of the connection seat 3. In some specific embodiments, the number of dampers 61 is two, which are distributed on both sides of the connection seat 3 along the length direction of the main beam 41, and can be arranged in a substantially symmetrical manner.

[0028] For details, please refer to Figure 3 and Figure 4 , the main beam 41 is provided with a rotating shaft support 41a, the heliostat bracket includes a rotating shaft 7, the rotating shaft 7 connects the rotating shaft support 41a and the connecting seat 3, the rotating shaft support 41a is provided with a first adapter 41a1, the connecting seat 3 is provided with a second adapter 31, and one end of each of the two ends of the damper 61 is rotatably connected to the corresponding first adapter 41a1, and the other end is rotatably connected to the corresponding second adapter 31. In this embodiment, the first adapter 41a1 can be connected and fixed to the rotating shaft support 41a by fastener connection, welding, bonding, clamping, etc., or the first adapter 41a1 and the rotating shaft support 41a can be an integral part. Similarly, the second adapter 31 can be connected and fixed to the connecting seat 3 by fastener connection, welding, bonding, clamping, etc., or the second adapter 31 and the connecting seat 3 can be an integral part. Of course, the second adapter 31 can also be arranged at the output end of the azimuth drive device 2, or the second adapter 31 can be arranged at both the connection base 3 and the output end of the azimuth drive device 2. The damper 61 is hingedly connected to the first adapter 41a1 and the second adapter 31 by a pin.

[0029] In this embodiment, since there is a gap at each active node connection, such as the connection of the rotating shaft 7, the heliostat will shake in a strong wind environment. By setting the damper 61, the wind vibration energy of the heliostat can be quickly consumed, so that the heliostat can remain stable under normal working wind speed, thereby reducing the influence of wind vibration on the light spot, and even ensuring that the light spot is not affected by wind vibration. In addition, compared with the method of enhancing the overall rigidity of the heliostat, the overall price of the method of setting the damper will be lower, and it is more cost-effective among heliostats of the same level; and the installation is convenient and flexible, and it can be strengthened for heliostats with strong wind strength, and the damper 61 is located on the outside of the connecting seat 3, which is convenient for replacement.

During the actuation of the push rod 51, the retaining mechanism 52 moves relative to the supporting portion 41b1.

By setting the retaining mechanism 52, during the movement of the push rod, the bearing connector 522 connected to the bearing seat 521a of the sliding bearing 521 contacts the push rod support 41b and maintains the transmission of the radial force on the inner tube, further enhancing the stability of the push rod and reducing the impact of strong winds on the push rod.

In this embodiment, by providing the rolling contact assembly 523, the friction between the bearing connector 522 and the support portion 41b1 is reduced by rolling, thereby effectively extending the service life of the push rod support 41b and the bearing connector 522. Specifically, the bearing connector 522 includes a first connector 522a and a second connector 522b, the first connector 522a is connected and fixed to the second connector 522b, and the two can be connected by means of fasteners, or by means of welding, bonding, clamping, etc., or they can be set as an integral part, the second connector 522b is connected and fixed to the outer shell 51a, for example, by fasteners, the first connector 522a serves as a supporting part for the rolling contact assembly 523 and the bearing seat 521a, the first support 521a1 is connected and fixed to the first connector 522a, or the first support 521a1 and the first connector 522a can be set as an integral part.

In other words, the bearing connector 522 and each support portion 41b1 are in contact through at least one rolling contact assembly 523. The structural composition of the rolling contact assembly 523 and the connection between the rolling contact assembly 523 and the bearing connector 522, more specifically, the connection between the rolling contact assembly 523 and the first connection portion 522a are as follows:

In this embodiment, the bearing 523b is a radial bearing, the inner ring of the bearing 523b cooperates with the ball plunger 523a, and the outer ring of the bearing 523b cooperates with the bearing cap 523c. In addition, the bearing cap 523c is connected and locked with the bearing connector 522 by fasteners (not shown in the figure), which facilitates the replacement of the parts of the rolling contact assembly 523.

[0039] In this embodiment, the stability of the heliostat is greatly improved through the combined effect of the damping device 6 and the holding mechanism 52, thereby achieving the improvement of the stability of the reflector surface and the wind resistance of the heliostat. At the same time, the present application reduces the cost by setting a damper compared to the method of achieving the stability of the heliostat under wind load by increasing the mechanical rigidity of the mirror frame.

[0040] Please refer again Figure 7 , the outer shell 51a of the push rod 51 is rotatably connected to the push rod support 41b.

The control system 9 performs analysis. When the reflector group 10 needs to be adjusted, the control system 9 sends a control signal to the azimuth drive device 2 and / or the elevation drive device 5. The mirror frame 4 is adjusted by at least one of the azimuth drive device 2 and the elevation drive device 5, and then the reflector group 10 is adjusted until the reflector group 10 projects the reflected light to the set area on the heat absorber according to the mirror field design.

[0042] In this embodiment, the damping device 6 and the elevation angle driving device 5 are distributed on both sides of the main beam 41 to form a triangular stable support structure. When the heliostat provided in this embodiment is working, when the reflected light of the reflector group 10 needs to be adjusted after being processed and analyzed by the sight 8 and the control system 9, the azimuth angle is adjusted by the azimuth angle driving device 2, and / or the elevation angle is adjusted by the elevation angle driving device 5, until the sunlight reflected by the reflector group 10 is accurately projected to the set area on the heat absorber. Especially when working in a strong wind environment, the damping device 6 can quickly consume the wind vibration energy of the heliostat, so that the heliostat remains stable, thereby ensuring that the light spot formed by the reflection is not affected by the wind vibration. In addition, in a strong wind environment, the force of the strong wind on the mirror frame 4 is transmitted to the retaining mechanism 52, and the spring in the ball plunger 523a can be adaptively adjusted to reduce or eliminate the force of the wind-induced vibration on the push rod, so that the push rod does not directly bear the radial force, and ensure that the push rod is not damaged in strong winds.
