[0026] Embodiment 1

[0027] like Figures 1 to 3 As shown, a heliostat installation mechanism for a tower-type solar thermal power station includes an installation and fixing component 1, a control and adjustment component 2 is installed on the top of the installation and fixing component 1, and a signal transmission component 3 is connected to the top of the control and adjustment component 2; the control and adjustment component 2 includes a mounting frame 201, a motor 202, a threaded rod 203, a bearing 204, a support rod 205, a fixing plate 206, a rotating shaft 207, a heliostat body 208, an electric lift 209, and a connecting ball 210. The control and adjustment component 2 can adjust the horizontal position and vertical angle of the heliostat body 208. The support rod 205 forms a sliding structure with the mounting frame 201 through the threaded rod 203, and the .... The rod 205 is threadedly connected with the threaded rod 203, and the threaded rod 203 forms a rotating structure with the mounting frame 201 through the bearing 204. The connecting ball 210 forms a sliding structure with the heliostat body 208 through the electric lift 209, and the heliostat body 208 forms a rotating structure with the fixing plate 206 through the rotating shaft 207. The control and adjustment component 2 can adjust the horizontal position of the heliostat body 208 under the drive of the motor 202, and at the same time, under the drive of the electric lift 209, the heliostat body 208 can adjust the vertical angle through the rotating shaft 207, so that the horizontal position and vertical angle of the heliostat body 208 can be accurately adjusted.

[0028] like Figure 1 and Figure 4As shown, a heliostat installation mechanism for a tower-type solar thermal power station, a signal transmission component 3, includes a sunlight tracking sensor 301, a processor 302, a telescopic shell 303, a sliding inner core 304, a power supply 305, a rotating piece 306, and a control power supply 307. The sunlight tracking sensor 301 is used to monitor the angle and position of the heliostat body 208 in real time. The sliding inner core 304 and the rotating piece 306 form a sliding structure through the telescopic shell 303, and the rotating piece 306 and the control power supply 307 form a rotating structure through the power supply 305. The processor 302, the control power supply 307, the motor 202, and the electric lift 209 are all electrically connected; by providing the sunlight tracking sensor 301, the sunlight tracking sensor 301 is installed on the mounting frame 201, and is used to monitor the angle and position of the heliostat body 208 in real time, and transmit the data to the processor 302 for analysis and processing, so as to accurately adjust the angle and position of the heliostat body 208.

[0029] like Figure 1 and Figure 5 As shown, a heliostat installation mechanism for a tower-type solar thermal power station includes an installation and fixing assembly 1, including a fixing seat 101, a mounting plate 102, a support plate 103, and a mounting hole 104. The fixing seat 101 can be used to provide support for the entire device, and the heliostat body 208 is installed and fixed through the mounting hole 104. The mounting holes 104 are arranged at equal intervals about the inside of the mounting plate 102, and the mounting plate 102, the support plate 103 and the fixing seat 101 form a right triangle with the fixing seat 101 and the mounting plate 102 as right-angled sides; the fixing seat 101 can be used to provide support for the entire device, and the fixing seat 101 can be installed and fixed through the mounting hole 104, so as to install and fix the heliostat body 208, thereby ensuring the stability of the position of the heliostat body 208 after adjustment. In addition, the fixing seat 101, the mounting plate 102, and the support plate 103 form a triangle, which can ensure that the heliostat body 208 is installed and fixed more securely.

[0030] Working principle: First, the fixing seat 101 is made of high-strength steel or concrete, and a mounting hole 104 is provided at the bottom, through which the device can be installed. In addition, a support plate 103 is provided, and the support plate 103 is tilted and arranged on the side of the fixing seat 101 and the mounting plate 102. At this time, the fixing seat 101, the mounting plate 102, and the support plate 103 form a triangle. The principle of stability of the triangle can be used to make the device more securely fixed. Then, by providing a sunlight tracking sensor 301, the detected data is transmitted to the processor 3 according to the position of the sunlight. 02, and after being analyzed by the processor 302, it will begin to transmit in the form of an electrical signal, so that the sliding inner core 304 extends from the telescopic shell 303 and presses against the rotating piece 306, so that the rotating piece 306 rotates around the power supply 305 and finally touches the control power supply 307. Since the power supply 305 can provide electricity, and the processor 302, the control power supply 307, the motor 202 and the electric lift 209 are electrically connected, when the rotating piece 306 touches the control power supply 307, the circuit between the motor 202 and the electric lift 209 will be connected;

[0031] Next, the motor 202 drives the threaded rod 203 to rotate, and the threaded rod 203 rotates in the mounting frame 201 through the bearing 204. The heliostat body 208 moves horizontally in the mounting frame 201 through the support rod 205. At the same time, the switch of the electric lift 209 is turned on. The electric lift 209 makes the connecting ball 210 slide up and down in the heliostat body 208, and the heliostat body 208 rotates through the rotating shaft 207, so that the heliostat body 208 starts to move. The heliostat body 208 will eventually follow the position of the sun. When the sun deflects a certain angle, generally about 5 to 10 minutes, the processor 302 will issue a command, so that the heliostat body 208 will adjust the horizontal position and vertical angle accordingly, and stop when it reaches the position facing the sun, waiting for the next sun deflection angle, and keep moving intermittently. When it is cloudy or at night when the sun does not appear, it stops moving. As long as the sun appears, it will automatically find and track it in place. When the sun is out of the adjustable angle, the processor 302 will issue a command to stop the device.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
