[0008] Preferably, in order to improve the compression resistance of the photovoltaic mounting panel, a support frame is installed on one side of the connecting column, and a support angle plate is rotatably installed on the top of the support frame.

[0011] Preferably, the reinforcing rods are obliquely arranged at the bottom of the reinforcement tube, and the two groups of reinforcing rods are in an eight-shaped shape.

[0012] A method for using the above-mentioned photovoltaic bracket with pressure-resistant and wind-proof functions comprises the following steps: Preferably, in the preparation stage, the support base plate is moved to a desired outdoor position, then the support rod and its protective mechanism are fixedly installed with the photovoltaic mounting board, and then the photovoltaic panel to be used is installed on the surface of the photovoltaic mounting board; Preferably, during the use phase, the photovoltaic panel is supported by the support base plate, the support rod, the protection mechanism and the photovoltaic mounting plate, so that the photovoltaic panel performs photovoltaic power generation; Preferably, in the windproof stage, when the support pole is affected by strong wind, a windproof net is used to buffer the wind; Preferably, in the compression resistance stage, when the photovoltaic installation panel is under pressure, the photovoltaic installation panel is supported by rotating the supporting angle plate under pressure; Preferably, during the protection stage, when snow accumulates on the photovoltaic panels on the surface of the photovoltaic installation panel, the photovoltaic installation panel and the photovoltaic panels are gradually tilted by utilizing the protection mechanism, and the snow on the surface of the photovoltaic panels slides down from the lowest end of the photovoltaic panels under the action of gravity.

[0017] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0018] Embodiment 1 The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 4 , this application provides a photovoltaic bracket with pressure resistance and wind resistance, please refer to Figure 1 and Figure 2 , including a support base plate 1, support rods 2 and a photovoltaic mounting plate 6; two groups of support rods 2 are movably installed inside the support base plate 1, a reinforcement mechanism 3 is installed on the outside of the support rods 2, a protection mechanism 4 is fixedly installed between the support rods 2, and a photovoltaic mounting plate 6 is installed on the top of the support rods 2; The protection mechanism 4 includes a connecting column 401, a hydraulic damper 1 402, a hydraulic damper 2 403 and a buffer spring 404. The connecting column 401 is fixedly installed between the two groups of support rods 2. Two groups of hydraulic dampers 1 402 are rotatably installed on one side of the connecting column 401. Two groups of hydraulic dampers 2 403 are rotatably installed on the side of the connecting column 401 away from the hydraulic damper 1 402. The outer sides of the moving ends of the hydraulic dampers 1 402 and the hydraulic dampers 2 403 are both wrapped with buffer springs 404. The moving ends of the hydraulic dampers 1 402 and the hydraulic dampers 2 403 are rotatably connected to photovoltaic mounting panels 6.

[0019] Specifically, a complete photovoltaic bracket is formed by the bracket base plate 1, the bracket rod 2 and the photovoltaic mounting plate 6, which is used to install the photovoltaic panel for use. The reinforcement mechanism 3 is used to improve the support of the bracket rod 2, and the protection mechanism 4 is used to improve the wind resistance and pressure resistance of the photovoltaic bracket. The hydraulic damper 1 402 and the hydraulic damper 2 403 have the same structure. The hydraulic damper 1 402 and the hydraulic damper 2 403 are based on the principles of fluid mechanics and mechanical kinematics. Energy is consumed by the flow of liquid in the hydraulic damper 1 402 or the hydraulic damper 2 403 and the friction of the damping material. When the instantaneous blowing force generated by the external wind is large, one side of the photovoltaic mounting plate 6 is lifted up, and the other side of the photovoltaic mounting plate 6 will move downward, driving the hydraulic damper 1 402 to produce an instantaneous impact load. The hydraulic damper When the damper 2 403 is stretched instantaneously, the pressure inside the hydraulic damper 1 402 increases and reaches the locking pressure value, a damping force is formed to lock the hydraulic damper 1 402, thereby improving the wind resistance and pressure resistance of the photovoltaic bracket. The buffer spring 404 can buffer the hydraulic damper 1 402 and the hydraulic damper 2 403, and at the same time assist the mobile ends of the hydraulic damper 1 402 and the hydraulic damper 2 403 to reset. When snow accumulates on the photovoltaic panel on the surface of the photovoltaic mounting panel 6 and the pressure on the photovoltaic mounting panel 6 gradually increases, the hydraulic damper 1 402 and the hydraulic damper 2 403 are used to compress the photovoltaic mounting panel 6 and the photovoltaic panel gradually tilted, and the snow on the surface of the photovoltaic panel will slide directly from the lowest end of the photovoltaic panel under the action of gravity. When snow accumulates on the photovoltaic panel on the surface of the photovoltaic mounting panel 6 and the pressure on the photovoltaic mounting panel 6 gradually increases, the hydraulic damper 402 is compressed to make the photovoltaic mounting panel 6 and the photovoltaic panel gradually tilt, and the snow on the surface of the photovoltaic panel will slide directly from the lowest end of the photovoltaic panel under the action of gravity.

[0020] Please refer to Figure 2 A limiting plate 203 is installed on the outer side of the bracket rod 2 close to the top of the reinforcement mechanism 3, and the limiting plate 203 is located at the bottom of the connecting column 401.

[0021] Specifically, in order to limit the connection column 401 during installation and prevent the connection column 401 from slipping due to loose screws of installation parts, the limit plate 203 is fixed to the outside of the bracket rod 2 by welding. The bottom of the connection column 401 can be supported and positioned by the limit plate 203, which is convenient for workers to fix the connection column 401 and the bracket rod 2, and at the same time, it can prevent the connection column 401 from slipping downward due to loose installation parts.

[0022] Please refer to Figure 1 A fixing rod 104 is installed on the outer side of the bracket bottom plate 1, and a windproof net 102 is fixedly installed inside the fixing rod 104.

[0023] Specifically, in order to initially reduce the wind force exerted on the support rod 2 and prevent the support rod 2 from being deformed due to wind force during long-term outdoor use, workers use bolts to fix the windproof net 102 inside the fixing rod 104. By distributing multiple groups of fixing rods 104 at equal distances around the support base plate 1, the support for the windproof net 102 can be improved, and the windproof net 102 can block part of the wind force and reduce the force exerted on the support rod 2.

[0024] Please refer to Figure 3 The reinforcement mechanism 3 includes a reinforcement tube 301 and a reinforcement rod 302. The reinforcement tube 301 is fixedly installed on the outer side of the bracket rod 2. Two groups of reinforcement rods 302 are symmetrically installed on the bottom of the reinforcement tube 301. The reinforcement rods 302 are inclined at the bottom of the reinforcement tube 301, and the two groups of reinforcement rods 302 are in an eight-shaped shape.

[0025] Specifically, in order to improve the support of the bracket rod 2, two groups of reinforcing rods 302 are connected to the top reinforcement tube 301 in an eight-shaped shape. The support of the bracket rod 2 can be improved by the reinforcing rods 302 and the reinforcement tube 301, thereby extending the service life of the bracket rod 2.

[0026] Please refer to Figure 4 A guide groove 101 is provided inside the bracket bottom plate 1, and a guide rod 103 is installed inside the guide groove 101. A slider 201 is provided at the bottom end of the bracket rod 2. The slider 201 moves to the outside of the guide rod 103. Springs 202 are installed and wrapped around the outside of the guide rod 103 at both ends of the slider 201. One end of the spring 202 is connected to the inner wall of the guide groove 101, and the other end of the spring 202 is connected to the outer wall of the slider 201.

[0027] Specifically, in order to buffer the impact of the bracket rod 2, when the external wind force changes, the bracket rod 2 is pushed to move, and the slider 201 will move along the outer side of the guide rod 103 inside the guide groove 101. At this time, the spring 202 will be compressed and deformed. The deformation of the spring 202 can reduce the impact force on the bracket rod 2. When the wind stops, the spring 202 is not subjected to the thrust, and the spring 202 will drive the slider 201 to automatically reset.

[0028] Embodiment 2 Please refer to Figure 2 On the basis of the first embodiment, a support frame 5 is installed on one side of the connecting column 401, and a support angle plate 501 is rotatably installed on the top of the support frame 5.

[0029] Specifically, in order to improve the compression resistance of the photovoltaic mounting panel 6, the supporting angle plate 501 is L-shaped, and the supporting frame 5 is connected to the supporting angle plate 501 through a coil spring rod. When one side of the photovoltaic mounting panel 6 is pressed downward under the action of an external force, the bottom of the photovoltaic mounting panel 6 will contact one side of the supporting angle plate 501. At this time, the supporting angle plate 501 rotates, and the other side of the supporting angle plate 501 will generate an upward thrust on the bottom of the photovoltaic mounting panel 6, which can then support the photovoltaic mounting panel 6, thereby further improving the compression resistance of the photovoltaic mounting panel 6.

[0030] A method for using the above-mentioned photovoltaic bracket with pressure-resistant and wind-proof functions comprises the following steps: In the preparation stage, the support base plate 1 is moved to the desired outdoor position, and then the support rod 2 and its protective mechanism 4 are fixedly installed with the photovoltaic mounting plate 6, and then the photovoltaic panel to be used is installed on the surface of the photovoltaic mounting plate 6; In the use phase, the photovoltaic panel is supported by the support base plate 1, the support rod 2, the protection mechanism 4 and the photovoltaic mounting plate 6, so that the photovoltaic panel performs photovoltaic power generation; In the windproof stage, when the support rod 2 encounters strong wind, the windproof net 102 is used to buffer the wind; In the compression resistance stage, when the photovoltaic installation panel 6 is compressed, the photovoltaic installation panel 6 is supported by the support angle plate 501 rotating under compression; In the protection stage, when snow accumulates on the photovoltaic panels on the surface of the photovoltaic mounting panel 6, the protection mechanism 4 is used to gradually tilt the photovoltaic mounting panel 6 and the photovoltaic panels, and the snow on the surface of the photovoltaic panels will slide down from the lowest end of the photovoltaic panels under the action of gravity.

[0031] Working principle: In the initial state, the photovoltaic mounting board 6 is tilted by the different lengths of the hydraulic damper 1 402 and the hydraulic damper 2 403, and the supporting angle plate 501 does not contact the photovoltaic mounting board 6; When in working state, the photovoltaic mounting panel 6 is blown by the wind, and part of the wind force can be initially blocked by the windproof net 102. When the instantaneous blowing force generated by the external wind is large and lifts up one side of the photovoltaic mounting panel 6, the other side of the photovoltaic mounting panel 6 will move downward, driving the hydraulic damper 402 to produce an instantaneous impact load, so that the hydraulic damper 402 is locked. At the same time, the bottom of the photovoltaic mounting panel 6 will contact one side of the supporting angle plate 501, prompting the supporting angle plate 501 to rotate, and the other side of the supporting angle plate 501 will generate an upward thrust on the bottom of the photovoltaic mounting panel 6, which can then support the photovoltaic mounting panel 6.

[0032] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
