DETAILED DESCRIPTION

[0043] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0044] Example 1: Figure 1-6 As shown, the present invention provides a technical solution, a photovoltaic power generation suspension support system capable of synchronously adjusting the angle of a photovoltaic panel, comprising a photovoltaic support unit; the photovoltaic support unit comprises a fixed support plate 1, a sound generating assembly 2 is mounted on one side of the fixed support plate 1, and the sound generating assembly 2 comprises a fixed placement block 201, an inlet and outlet 202, an L-shaped support plate 203, a pneumatic reed 204, a floating plate 205, a water inlet 206, a transmission rod 207, a transmission fan 208, an impact reed 209, a fixed support frame 210, and a passive reed 211;

[0045] Several fixed placement blocks 201 are equidistantly installed on one side of the top of the fixed support plate 1. An inlet and outlet 202 is opened at one end of the fixed placement block 201. The cross section of the inlet and outlet 202 is trapezoidal, which can increase the airflow speed. An L-shaped support plate 203 is fixedly connected to one side of the top of the fixed placement block 201. Several pneumatic reeds 204 are connected to the bottom of the L-shaped support plate 203 by screws. The angle between the pneumatic reed 204 and the fixed placement block 201 is 60 degrees, which increases the contact area with the airflow without affecting the flow of the airflow. Several floating plates 205 are equidistantly fixedly connected to the bottom of the fixed support plate 1. A water inlet 206 is opened at one end of the floating plate 205. One end of the fixed support plate 1 rotates A transmission rod 207 runs through the transmission rod 207, and the bottom end of the transmission rod 207 is embedded and installed on the inner side of the water inlet 206. The bottom end of the transmission rod 207 is fixedly connected to a transmission fan 208. Guide plates 212 are respectively provided in the water inlet 206 on the front and rear sides of the transmission fan 208 to guide the water flow to impact one side of the transmission fan 208; an impact spring 209 is fixedly installed on the top of the transmission rod 207, and a fixed support frame 210 is fixedly connected to the top of the fixed support plate 1 near the impact spring 209. A passive spring 211 is clamped on the top of the fixed support frame 210, and a card interface is provided at one end of the fixed support frame 210. A fixed clamping column is embedded and clamped on the inner side of the card interface to facilitate replacement of the passive spring 211.

[0046] A mounting assembly 3 is installed on one side of the fixed support plate 1. The mounting assembly 3 includes a fixing box 301, a supporting spring 302, an auxiliary supporting plate 303, an auxiliary fixing plate 304, a snap-in slot 305, a limiting column 306, a telescopic slot 307, a limiting spring 308 and an L-shaped protective plate 309;

[0047] The top of the fixed support plate 1 is symmetrically fixedly connected with a fixed box 301 on both sides, and a support spring 302 is symmetrically fixedly connected to the inner side of the fixed box 301. The top of the support spring 302 is fixedly connected with an auxiliary support plate 303. The auxiliary support plate 303 is slidably installed on the inner side of the fixed box 301 to facilitate lifting and adjusting. An auxiliary fixing plate 304 is installed on the top of the auxiliary support plate 303. The maximum rotation angle of the auxiliary fixing plate 304 is 60 degrees to ensure the best light receiving angle. The auxiliary fixing plate 304 is hingedly connected to the fixed support plate 1 and a protruding end is provided at the hinged end of the auxiliary fixing plate 304. The stop strip, the auxiliary support plate 303 and one end of the fixing box 301 are provided with a snap-in groove 305, and the inner side of the snap-in groove 305 is embedded with a snap-in limiting column 306. A number of expansion grooves 307 are equidistantly provided at both ends of the auxiliary fixing plate 304. The inner side of the expansion groove 307 is symmetrically fixed with a limiting spring 308. One end of the limiting spring 308 is welded and installed on one end of the L-shaped protective plate 309. The L-shaped protective plate 309 is slidably embedded in the inner side of the expansion groove 307. The length and width of the L-shaped protective plate 309 are equal to the length and width of the expansion groove 307, which is convenient for limiting and fixing the photovoltaic panel.

[0048] The working principle and use process of embodiment 1: When the photovoltaic panel needs to be installed, the staff places the photovoltaic panel on the auxiliary fixing plate 304, and pulls the L-shaped protective plate 309 when placing it. When the L-shaped protective plate 309 is pulled, the limiting spring 308 is stretched synchronously. After the photovoltaic panel is fixed, the L-shaped protective plate 309 is released. Under the reset action of the limiting spring 308, the L-shaped protective plate 309 slides and resets along the telescopic groove 307, thereby limiting the photovoltaic panel to prevent it from deflecting or sliding during use. The auxiliary support plate 303 is pulled to move along the fixing box 301, and the support spring 302 supports the auxiliary support plate 303 during its movement to avoid accidents caused by insufficient supporting force. After the auxiliary fixing plate 304 is rotated to the required angle, the limit post 306 is embedded in the fixing slot 305 again, thereby completing the installation and angle adjustment of the photovoltaic panel, thereby facilitating the rapid maintenance and replacement of the photovoltaic panel and the adjustment of the light receiving angle.

[0049] During the use of the photovoltaic panel, water waves pass through the floating plate 205 and enter through the water inlet 206 and are then discharged. When the water waves pass through the water inlet 206, the water waves push the transmission fan 208, and the transmission fan 208 drives the transmission rod 207 to rotate, thereby driving the impact reed 209 to hit the passive reed 211, generating sound, and driving away birds by sound. When wind blows in the environment, the airflow passes through the inlet and outlet 202 at the position of the fixed placement block 201. At the position of the inlet and outlet 202, the airflow is further accelerated due to the large inlet and small outlet. After the airflow is accelerated in the fixed placement block 201, it reaches the position of the pneumatic reed 204. The pneumatic reed 204 vibrates under the action of the airflow to generate sound, thereby further achieving the effect of driving away birds. The reeds are driven by a variety of different driving methods, thereby ensuring the safety of the photovoltaic panel and the support frame.

[0055] Working principle and usage process of embodiment 2: The working principle of the sound-generating component is the same as that of embodiment 1;

[0056] When the inclination angle of the photovoltaic panel needs to be adjusted, water is pumped into the piston hole 422 by a pressurized water pump to push the piston body 423 to move outward to squeeze the lower end surface of the inner expansion groove 410 and the plug 413. In this process, due to the squeezing force of the upper and lower piston bodies 413, the outer expansion head 411 automatically moves to the middle of the inner expansion groove 410, and the entire cross bar 407 automatically adjusts to a straight line and maintains it, and adjacent segmented rods 409 can no longer move relative to each other; at the same time, the system controller controls the first electromagnet 433 to be energized. After being energized, the first electromagnet 433 attracts the first permanent magnet 432, pulls the stop pin 430 to separate from the serrated structure 428, and releases the stop, so that the moving block 426 can move along the track 425; then the controller controls the telescopic drive rod 406 to drive the slider 404 to move along the slide rail 405, so The cross bar 407 between the left and right relative sliders 404 is driven to move longitudinally. Due to the limitation of the limit guide 402, the photovoltaic panel and the auxiliary fixing plate 304 change their angles under the combined action of their own gravity and the component force in the vertical direction during the translation of the cross bar 407, thereby achieving a change in the angle of attack according to the change in the sun angle, thereby improving the power generation efficiency of the photovoltaic panel; in this process, the moving block 426 moves adaptively. When the adjustment is completed, the circuit of the first electromagnet 433 is disconnected, and the stop pin 430 moves toward the sawtooth structure 428 under the thrust of the thrust spring 434 and is re-inserted into the stopper with the sawtooth structure 428, so that the position of the moving block 426 is fixed, and the connecting rod 435, the fixed support plate 1 and the track 425 form a stable triangle, thereby forming a stable support for the fixed support plate 1 and the photovoltaic panel thereon.

[0057] According to the size of the wind and waves at sea, the degree of outward movement of the piston body 423 can be controlled by controlling the amount of water pumped into the piston hole 422, thereby adjusting the distance between the upper and lower ends of the outer expansion head 411 and the bottom of the inner expansion groove 410 and the plug, thereby adjusting the movable range of the outer expansion head 411, and then controlling the degree of relative movement of adjacent photovoltaic support units; the servo motor drives the cross bar 407 to rotate a certain angle, thereby controlling the orientation angle of the outer expansion head 411 and the inner expansion groove 410, thereby controlling the angle and direction of relative movement of adjacent photovoltaic support units, thereby adapting to complex and changing sea conditions and adapting to water surface fluctuations and lateral waves at different angles and directions; and the external force can be decomposed by utilizing the angle formed with the external force under different angles and orientations, thereby controlling the magnitude of the friction between the outer expansion head 411 and the inner expansion groove 410, thereby achieving a certain degree of controllability of the damping of the relative movement between the outer expansion head 411 and the inner expansion groove 410.

[0058] When the wind and waves are strong, the piston body 423 does not move outward, and the cross bar 407, the longitudinal bar 408 and the adjacent segmented bars 409 of the main bar 403 of the system frame 4 automatically move relative to each other according to the changes in the waves. Among them, the cross bar 407 can independently control the movable angle, direction and movable stroke according to the sea conditions, so that each photovoltaic support unit can freely change with the waves, buffering the impact of the waves on the entire system and the load caused by the system's own gravity due to the change in its own posture under the action of the waves; thereby reducing the overall structural strength requirements of the system, extending the service life, reducing costs, and improving the overall wind and wave resistance of the system; the relevant better control parameters of the cross bar 407 can be obtained in laboratory simulation or remotely controlled through real-time sea condition alarms.
