Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The mounting bracket for the polarization correction camera in a tower-type solar thermal power plant is an important component used to stably install the polarization correction camera and ensure that it can accurately acquire heliostat spot images in order to achieve heliostat error correction.

[0029] The polarization camera is typically mounted near the receiver to measure the tracking deviation of the heliostat at different times of the day. A mounting bracket is needed to stably fix the camera at a specific position and angle, enabling it to accurately capture and image the light spot focused onto the polarization plate by the heliostat, providing accurate data for heliostat calibration.

[0030] Design requirements for the fixed bracket of the correction camera in a tower solar thermal power plant.

[0031] Stability: Tower solar thermal power plants are usually located outdoors and may face severe weather such as strong winds and sandstorms. The fixed support needs to have sufficient strength and rigidity to ensure that the correction camera can be stably fixed under various environmental conditions, preventing it from shifting or shaking, and ensuring the accuracy of the camera's shooting.

[0032] Precision retention: Since the tracking accuracy of the heliostat is crucial to the power generation efficiency of the power plant, the installation position and angle accuracy of the correction camera directly affect the error correction effect. Therefore, the bracket must be able to maintain accuracy over a long period of time to reduce camera position shifts caused by environmental factors or changes in its own structure.

[0033] Thermal insulation performance: The temperature near the heat absorber is high, so the bracket needs to have good thermal insulation performance or be able to cooperate with thermal insulation components to avoid the high temperature affecting the normal operation of the correction camera and prevent the camera from freezing or being damaged.

[0034] Adjustability: In order to adapt to different calibration needs and installation conditions, the bracket should have a certain degree of adjustment function, which can easily adjust the position and angle of the correction camera to ensure that the camera can be accurately aligned with the heliostat field and the correction plate.

The first connecting plate is fixedly connected to one side of the angle steel of the camera fixing beam by bolts.

[0038] The angle steel is selected according to the specific scenario. Other profiles can be used to replace the heat insulation board support, but they should have sufficient strength. The number of ear plates and nut seats is not specifically limited; both ear plates and nut seats are fixedly connected to the heat insulation board support and have sufficient strength. An elongated hole is provided on the first connecting plate. The first stiffening plate should have sufficient strength, and its number is not specifically limited.

The heat insulation board used for the correction camera in the tower-type solar thermal power plant usually has the characteristics of good heat insulation performance, high temperature resistance, sufficient strength and rigidity, corrosion and aging resistance, lightweight, and easy installation and maintenance. The heat insulation board can be selected from heat-insulating glass, perforated plate, aluminum silicate ceramic fiber board, flexible nanofiber felt, and aerogel composite insulation felt, depending on the specific situation.

[0049] The pressure plate is made of angle steel, which is selected according to the specific scenario. Other profiles can also be used instead of the pressure plate, but they should have a certain strength. One side of the pressure plate has screw holes that correspond to the screw holes on the insulation board bracket, and the other side is used to press the insulation board.
