[0002] At present, in the field of photovoltaic power generation projects, photovoltaic brackets are an indispensable and important part of the entire project system. Photovoltaic brackets are composed of C-shaped steel, U-shaped steel, angle steel or square steel. The frame is fixed to the foundation through a fixed base. For photovoltaic brackets with this structure, the frame is fixedly connected to the fixed base. Once the angle of the frame is determined, it cannot be adjusted. However, the angle of sunlight is different throughout the year, and the angle of the frame cannot change with the angle of sunlight, and the best lighting effect cannot be achieved.

The application discloses an adjustable photovoltaic bracket. The design proposes a rotating device, a fixing device and a lifting device design, which solves the problem that the angle adjustment method is relatively troublesome and the angle adjustment is relatively limited. The secondary shaft is driven to rotate by the turning handle, and the first gear on the secondary shaft drives the second gear to rotate, and then the second gear drives the main shaft to rotate. Since the first connecting member and the second connecting member are both fixed on the main shaft, the first connecting member and the second connecting member also rotate accordingly, and drive the first longitudinal beam and the second longitudinal beam to rotate, so as to adjust the upper and lower angles, so as to achieve a simple bracket structure, convenient installation and disassembly, and can adjust the height and angle of the photovoltaic bracket. However, in the above-mentioned device, it is difficult to adjust the position of the photovoltaic panel according to the position of the sun through the mutual cooperation of components such as the rotating device, the fixing device and the lifting device, so that the photovoltaic panel can maximize the light reception while lubricating the device, reduce the power generation efficiency, increase the maintenance frequency, and reduce the service life of the equipment, which needs to be improved.

The design of the spring pump 209 can reduce wear, reduce maintenance frequency, and increase the service life of the equipment. At the same time, reasonable lubrication design ensures the smooth operation of moving parts.

[0036] The fixing rod 214 is located on the movement trajectory of the extrusion rod 218, and the bottom of the partition 212 is fixedly connected with a return spring 216. The end of the return spring 216 away from the partition 212 is fixedly connected to the inner wall of the spring pump 209, and the side of the gear 205 is meshed with the side of the rack 206. The top of the gear 205 is fixedly connected to the bottom of the support frame 102. The meshing of the gear 205 and the rack 206, the displacement of the support frame 102, etc., can ensure the stability of the photovoltaic panel 103 under various weather conditions and reduce the risk of damage caused by wind or other external factors.

[0037] A protective device 3 is provided on the top of the protective plate 101, and the protective device 3 includes a protective shell 301, which is fixedly connected to the top of the support frame 102. An electric wire 302 runs through the side of the protective shell 301, and an electric telescopic rod 303 is provided at one end of the electric wire 302 away from the protective shell 301. A hydraulic cylinder 304 is provided on the top of the protective plate 101, and one end of the hydraulic cylinder 304 is connected to a force rod 305 through a piston sliding connection, and the other end of the hydraulic cylinder 304 is connected to a hydraulic rod 308 through a piston sliding connection, and one end of the hydraulic rod 308 is fixedly connected to a clamping block 309, and the bottom of the threaded block 204 is fixedly connected to a rack rod 307.

[0038] One end of the electric telescopic rod 303 is rotatably connected to the side of the support frame 102, and the other end of the electric telescopic rod 303 is fixedly connected to the bottom of the photovoltaic panel 103. The force-bearing rod 305 is located on the displacement trajectory of the photovoltaic panel 103.

[0039] A compression spring 306 is fixedly connected to the circumferential surface of the force-bearing rod 305, and one end of the compression spring 306 away from the force-bearing rod 305 is fixedly connected to the side of the hydraulic cylinder 304.

The design of the compression spring 306 can make the force-bearing rod 305 automatically reset, reducing manual intervention.

[0040] In this embodiment, the present application drives the reciprocating screw 203 to rotate through the motor 202, and then drives the threaded block 204 to move through the rotation of the reciprocating screw 203, and drives the gear 205 to move through the displacement of the threaded block 204. Since the gear 205 is meshed with the rack 206, the gear 205 will rotate during the displacement process. The displacement and rotation of the gear 205 drives the support frame 102 to move and rotate, and then the displacement of the support frame 102 drives the photovoltaic panel 103 to move and rotate, so that the position and angle of the photovoltaic panel 103 can be adjusted according to the position of the sun, so that the photovoltaic panel 103 can maximize the effect of receiving light. The displacement of the reciprocating screw 203 drives the rotating gear 219 to rotate, and then the rotating gear 219 drives the gear plate 2 08 rotates, and the rotation rod 207 is driven to rotate by the rotation of the gear plate 208, and then the squeezing rod 218 is driven to rotate by the rotation of the rotating rod 207. The squeezing rod 218 squeezes the inclined surface of the fixed rod 214 to cause the fixed rod 214 to be displaced, and the fixed rod 214 is displaced to squeeze the inclined surface on the top of the fixed block 213 to cause the fixed block 213 to be displaced downward, and then the partition 212 is driven to be displaced downward by the fixed block 213, so that a gap appears on the side of the positioning plate 211, and the lubricating oil on the top of the spring pump 209 flows to the bottom of the spring pump 209, and then sprayed out through the oil outlet pipe 210. When the squeezing rod 218 is away from the fixed rod 214, the fixed rod 214 is reset by the elastic force of the spring 215, and the partition 212 is reset by the limit of the limit rod 217 and the elastic force of the reset spring 216.

[0041] When it rains, rainwater is collected inside the protective shell 301, and the accumulated water enters the protective shell 301. Due to the presence of electrolytes in the water, an electric current is formed, so that the water conducts the current between the electric conductors 302 to achieve conductivity, so that the electric telescopic rod 303 is powered on and starts to work, and the electric telescopic rod 303 drives the photovoltaic panel 103 to contract. At this time, the photovoltaic panel 103 is in a contracted state, and the photovoltaic panel 103 is displaced to squeeze the force-bearing rod 305, so that the force-bearing rod 305 is displaced inward to squeeze the piston inside the hydraulic cylinder 304, and the piston inside the hydraulic cylinder 304 pushes The liquid inside the hydraulic cylinder 304 pushes another piston to move, and the piston pushes the hydraulic rod 308 to move, and the displacement of the hydraulic rod 308 drives the block 309 to move, so that the block 309 is stuck in the rack rod 307, and the rack rod 307 stops moving, thereby stopping the threaded block 204 from moving. Therefore, the support frame 102 and the photovoltaic panel 103 stop moving and are in a static state, so that when it rains, the photovoltaic panel 103 automatically shrinks and stops moving, thereby preventing the photovoltaic panel 103 from being damaged by bad weather.
