[0002] Photovoltaic tracking bracket is a photovoltaic bracket system that can automatically adjust the angle of the module to follow the movement of the sun. Photovoltaic tracking bracket can maximize the efficiency of photovoltaic modules in capturing solar energy by automatically adjusting the angle of photovoltaic modules.

DETAILED DESCRIPTION

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0039] Embodiment 1:

[0040] See also Figure 1 — Fig.13 The present invention provides a technical solution: a photovoltaic tracking bracket, comprising:

[0041] The main body mechanism is used for installing and supporting the photovoltaic panel 107. The main body mechanism includes two columns 101 and multiple mounting plates 106. A reinforcing plate 102 is installed between the two ends of the two columns 101. A connecting shaft 103 is rotatably connected between the tops of the two columns 101 through a fixing cylinder.

Photovoltaic panels 107 are installed in multiple mounting grooves 108. Connecting plates 105 are installed at the bottoms of the multiple mounting plates 106. The connecting plates 105 are connected to the clamps 104.

[0042] The cleaning mechanism is used for sliding on the surface of the photovoltaic panel 107 to clean the surface of the photovoltaic panel 107, and spraying water to improve the cleaning effect of the photovoltaic panel 107. The cleaning mechanism includes rectangular through holes 309 opened on both sides of the surface of the mounting plate 106 and a water injection cylinder 311 installed at the bottom of the mounting plate 106. Slide blocks 304 are slidably connected in the two rectangular through holes 309. An inverted U-shaped frame 301 is installed between the surfaces of the two slide blocks 304, and the inverted U-shaped frame 301 is a hollow structure. A cleaning brush 303 is installed on the top of the inner side of the inverted U-shaped frame 301, and the cleaning brush 303 is in contact with the surface of the photovoltaic panel 107. A plurality of water outlet holes 302 are opened on the inverted U-shaped frames 301 on both sides of the cleaning brush 303. The inner cavity of the water injection cylinder 311 is slidably connected to a piston 319, and one end of the piston 319 is connected to A push rod 312 is connected, and an L-shaped transmission rod 310 is connected to the push rod 312. A connecting rod 305 is installed at the bottom of the slider 304, and the connecting rod 305 is connected to the L-shaped transmission rod 310. A sealing ring 317 is installed at one end of the opening of the water injection cylinder 311, and the push rod 312 slides through the sealing tube. The water injection cylinder 311 is connected with a mountain-shaped tube 314, and the mountain-shaped tube 314 is connected with a water inlet hose 313. The bottom of the inverted U-shaped frame 301 is connected with a connecting pipe 306, and the water inlet hose 313 is connected to the connecting pipe 306. Both sides of one end of the water injection cylinder 311 are connected with a water suction pipe 308, and a water storage tank 307 is connected between the two water suction pipes 308. First one-way valves 318 are installed on both sides of the inner cavity of the mountain-shaped tube 314, and second one-way valves 316 are installed in the inner cavities of the two water suction pipes 308.

[0043] The adjusting mechanism is used to automatically adjust the angle of the photovoltaic panel 107 installed on the main body. It can automatically adjust the orientation of the photovoltaic assembly according to the daily movement of the sun and seasonal changes to ensure that the photovoltaic assembly is always perpendicular to the sunlight, thereby improving the power generation efficiency. The adjusting mechanism includes a driven gear 201 installed on the outside of the connecting shaft 103, an angle sensor 204 and a light intensity sensor 205 installed on the installation frame, and a control system 203 installed on one side of the column 101. The driven gear 201 is meshed with a driving gear 202, and a motor is provided on the driving gear 202. The control system 203 includes a controller and a communication module;

[0044] The limiting mechanism is used to adjust the mechanism so that when the photovoltaic panel 107 is tilted at a certain angle, the cleaning mechanism structure limits and automatically slides to clean the dust on the surface of the photovoltaic panel 107. The limiting mechanism includes plug-in slots 403 opened on both sides of the inner cavity of the rectangular through hole 309, and the bottom ends of the inner cavities of the two plug-in slots 403 are provided with connecting holes 406. The two connecting holes 406 are slidably connected with plug plates 404, and the bottoms of the two plug plates 404 are connected with pull rods 405. The bottoms of the plug plates 404 and the bottom ends of the inner cavities of the connecting holes 406 are connected with return springs 407. The bottoms of the two pull rods 405 are connected with traction ropes 402. Multiple fixing plates 401 are installed at one end of the outer sides of the two reinforcement plates 102, and the other ends of the two traction ropes 402 are connected to the fixing plates 401. , hooks 408 are installed at both ends of the slider 304. When working, the current angle of the photovoltaic bracket is monitored in real time through the angle sensor 204 to ensure that the bracket can be accurately adjusted according to the position of the sun, and then the light intensity sensor 205 measures the intensity of sunlight to help the control system 203 determine whether it is necessary to adjust the angle of the bracket to capture more sunlight. When the angle needs to be adjusted, the data input by the angle sensor 204 and the light intensity sensor 205 are processed by the central controller (not shown) of the control system 203, and the optimal photovoltaic component angle is calculated according to a preset algorithm, and then a signal is sent to the actuator (such as a motor not shown), thereby driving the driving gear 202 to rotate and cooperate with the driven gear 201 to drive the connecting shaft 103 to rotate. The photovoltaic panel 107 is adjusted to an angle so that the photovoltaic panel 107 is always perpendicular to the sunlight, thereby improving the power generation efficiency. When the photovoltaic panel 107 needs to be cleaned, a command is sent through the background and received by the communication module of the control system 203, and then the motor (not shown) is controlled to tilt to the cleaning angle of the photovoltaic panel 107 (the angle is greater than the tilt angle of the photovoltaic panel 107 when it is working normally), so that the installation frame pulls the traction rope 402 to drive the connecting rod 305 to move and then pulls the plug plate 404 out of the hook 408, so that the inverted U-shaped frame 301 slides downward in the tilted direction due to gravity, thereby cooperating with the cleaning brush 303 to automatically clean the dust on the surface of the photovoltaic panel 107, and while the inverted U-shaped frame 301 slides downward, the connecting rod 305 cooperates with the L-shaped transmission rod 31 0 moves, thereby driving the push rod 312 to push the piston 319 to move, and the first one-way valve 318 can only allow the water in the water injection cylinder 311 to flow into the mountain-shaped tube 314, and the second one-way valve 316 can only allow the water in the water storage tank 307 to enter the water injection cylinder 311 through the water suction pipe 308, so that the piston 319 moves in the direction of the photovoltaic panel 107 to tilt the water in the water injection cylinder 311 through the mountain-shaped tube 314 and the water inlet hose 313 and then discharge it through the water outlet hole 302 to the surface of the photovoltaic panel 107, thereby cooperating with the cleaning brush 303 to improve the cleaning effect of the photovoltaic panel 107. When the piston 319 moves to one side, the water in the water storage tank 307 is sucked into the water injection cylinder 311 on the opposite side of the moving direction of the piston 319 in cooperation with the water suction pipe 308.Thereby, it is ensured that there is always water in the water injection cylinder 311, so that when the photovoltaic panel 107 tilts to the other side, the inverted U-shaped frame 301 slides to the other side, driving the piston 319 to move and the water in the water injection cylinder 311 can be sprayed on the photovoltaic panel 107 through the water outlet 302, thereby ensuring that the photovoltaic panel 107 can spray water no matter which side it tilts to improve the cleaning effect of the photovoltaic panel 107, and when the inverted U-shaped frame 301 slides to one side of the photovoltaic panel 107, the traction rope 402 on the same side is in a relaxed state, so that the elastic force of the reset spring 407 pushes The plug plate 404 is placed in the plug slot 403. When the hook 408 is placed in the plug slot 403, since one side of the plug plate 404 is set as an inclined surface, the gravity of the inverted U-shaped frame 301 pushes the hook 408 to squeeze the plug plate 404 and push the return spring 407 to compress, so that the hook 408 passes over the plug plate 404 to limit the plug plate 404, thereby limiting the inverted U-shaped frame 301, thereby preventing the photovoltaic panel 107 from sliding due to the angle adjustment during operation, thereby blocking the photovoltaic panel 107 and affecting the power generation efficiency of the photovoltaic panel 107.

[0045] Among them, a rotating joint 315 is installed at the connection between the mountain-shaped tube 314 and the water inlet hose 313. When the inverted U-shaped frame 301 slides to clean the photovoltaic panel 107, the water inlet hose 313 moves along with the sliding of the inverted U-shaped frame 301, so that the water inlet hose 313 and the connection between the mountain-shaped tube 314 are rotatably connected through the rotating joint 315, thereby preventing the inverted U-shaped frame 301 from moving to the connection between the mountain-shaped tube 314 and the water inlet hose 313, causing the water inlet hose 313 to bend and hindering the sliding of the inverted U-shaped frame 301 to clean the surface of the photovoltaic panel 107.

[0046] Embodiment 2:

[0047] See also Figure 1 — Fig.13On the basis of the first embodiment, the present invention provides a technical solution: the inner cavity of the water tank 307 is slidably connected with a sealing push plate 704, an electric telescopic rod 702 is connected between the sealing push plate 704 and the inner cavity of the water tank 307, a tilt sensor 701 is installed on one side of the inverted U-shaped frame 301, and an exhaust hole 703 is provided on one side of the inner cavity of the water tank 307. The exhaust hole 703 is convenient for ensuring that the internal and external pressures of the water tank 307 above the sealing push plate 704 are the same, so as to ensure that the sealing push plate 704 can move in the water tank 307. A circular groove 601 is provided at one end of the inner cavity of the rectangular through hole 309, and a radar speed sensor 602 is installed in the circular groove 601. When working, the tilt angle of the photovoltaic panel 107 is monitored by the tilt sensor 701, and the sliding speed of the inverted U-shaped frame 301 is monitored by the radar speed sensor 602. When the tilt angle of the photovoltaic panel 107 reaches the inverted U-shaped frame 301, the inverted U-shaped frame 301 automatically slides. When the radar speed sensor 602 detects that the inverted U-shaped frame 301 has not moved, the radar speed sensor 602 sends a signal to a processor (not shown), and then the processor starts the electric telescopic rod 702 to push the sealing push plate 704 to move downward, thereby pressurizing the water tank 307, so that the water in the water tank 307 is pressurized and transported to the water injection cylinder 311 through the suction pipe 308, so that the pressurized water assists in pushing the piston 319 to move, and then assists in moving the push rod 312 and the L-shaped transmission rod 310, and then assists in driving the inverted U-shaped frame 301 to slide on the photovoltaic panel 107, thereby avoiding the dust on the photovoltaic panel 107 being thick or there is snow on the photovoltaic panel 107. When there is snow on the photovoltaic panel 107, it is prevented from hindering the sliding of the inverted U-shaped frame 301 and the water outlet 302 from spraying water to clean the dust or snow on the photovoltaic panel 107, so that the dust on the surface of the photovoltaic panel 107 can be cleaned while the snow on the photovoltaic panel 107 can be cleaned.

[0048] As a further embodiment of the present invention, the outer side of the mountain-shaped tube 314 and the outer side of the water injection cylinder 311 are both wrapped with electric heating tape 501, a temperature sensor 502 is installed on one side of the inner cavity of the water tank 307, and a heating block 503 is installed on one side of the bottom end of the inner cavity of the water tank 307. The water temperature in the water tank 307 is monitored by the temperature sensor 502. When the water temperature in the water tank 307 reaches zero degrees Celsius, the heating block 503 and the electric heating tape 501 are started by the processor to prevent the water in the water tank 307, the water injection cylinder 311 and the mountain-shaped tube 314 from freezing in cold weather and affecting the sliding of the inverted U-shaped frame 301 to clean the dust or snow on the surface of the photovoltaic panel 107. When the water temperature in the water tank 307 reaches the maximum temperature threshold set by the temperature sensor 502, the heating block 503 and the electric heating tape 501 are controlled by the processor to stop working.

[0049] As a further embodiment of the present invention, a water level sensor 803 is installed at the bottom end of the inner cavity of the water tank 307, and the bottom end of the water tank 307 is connected to a water supply pipe 801, and an electromagnetic valve 802 is installed in the water supply pipe 801. The water level in the water tank 307 is monitored by the water level sensor 803. When the water level in the water tank 307 is lower than the set minimum water level threshold of the water level sensor 803, the electromagnetic valve 802 is started by the processor to open and water is supplied to the water tank 307 through the water supply pipe 801. At the same time, the electric telescopic rod 702 is started by the processor to pull the sealing push plate 704 upward. When the water level in the water tank 307 reaches the set maximum water level threshold of the water level sensor 803, the electromagnetic valve 802 is automatically closed by the processor to stop supplying water, thereby ensuring that there is always sufficient water in the water tank 307 to clean the photovoltaic panel 107.

[0050] Working principle of the present invention:

[0051] When it is necessary to clean the photovoltaic panel 107, an instruction is sent through the background and received by the communication module of the control system 203, which controls the motor (not shown) to tilt to the cleaning angle of the photovoltaic panel 107 (the angle is greater than the tilt angle of the photovoltaic panel 107 when it is working normally), so that the installation frame pulls the traction rope 402 to drive the connecting rod 305 to move and then pulls the plug plate 404 to disengage from the hook 408, so that the inverted U-shaped frame 301 slides downward in the tilted direction due to gravity, thereby cooperating with the cleaning brush 303 to automatically clean the dust on the surface of the photovoltaic panel 107, and while the inverted U-shaped frame 301 slides downward, the connecting rod 305 drives the L-shaped transmission rod 310 to move, thereby driving the push rod 312 to push the piston 319 to move, and cooperating with the first one-way valve 318 to only fill the water injection cylinder 31 1 flows into the mountain-shaped pipe 314, and the second one-way valve 316 can only allow the water in the water tank 307 to enter the water injection cylinder 311 through the water suction pipe 308, so that the piston 319 moves in the direction of the photovoltaic panel 107 to tilt, and the water in the water injection cylinder 311 passes through the mountain-shaped pipe 314 and the water inlet hose 313 and is discharged through the water outlet hole 302 to the surface of the photovoltaic panel 107, thereby cooperating with the cleaning brush 303 to improve the cleaning effect of the photovoltaic panel 107. When the piston 319 moves to one side, the water in the water tank 307 is sucked into the water injection cylinder 311 on the side opposite to the moving direction of the piston 319 in cooperation with the water suction pipe 308, thereby ensuring that there is always water in the water injection cylinder 311, so that when the photovoltaic panel 107 tilts to the other side, the inverted U-shaped frame 301 moves to When the other side slides, the piston 319 is driven to move and the water in the water injection cylinder 311 can be sprayed on the photovoltaic panel 107 through the water outlet 302, thereby ensuring that the photovoltaic panel 107 can spray water no matter which side it is tilted to, thereby improving the cleaning effect of the photovoltaic panel 107, and when the inverted U-shaped frame 301 slides to one side of the photovoltaic panel 107, the traction rope 402 on the same side is in a relaxed state, so that the elastic force of the return spring 407 pushes the plug plate 404 to be placed in the plug groove 403, and when the hook 408 is placed in the plug groove 403, since one side of the plug plate 404 is set as an inclined surface, the gravity of the inverted U-shaped frame 301 pushes the hook 408 to squeeze the plug plate 404 and push the return spring 407 to compress, so that the hook 408 passes over the plug plate 404 to limit the plug plate 404 , thereby limiting the inverted U-shaped frame 301, thereby preventing the photovoltaic panel 107 from sliding due to the angle adjustment during operation and blocking the photovoltaic panel 107, affecting the power generation efficiency of the photovoltaic panel 107. When the photovoltaic panel 107 is cleaned, the inclination angle of the photovoltaic panel 107 is monitored by the inclination sensor 701, and the sliding speed of the inverted U-shaped frame 301 is monitored by the radar speed sensor 602. When the inclination angle of the photovoltaic panel 107 reaches the automatic sliding angle of the inverted U-shaped frame 301, the radar speed sensor 602 detects that the inverted U-shaped frame 301 has not moved, and the radar speed sensor 602 sends a signal to the processor (not shown), and then the processor starts the electric telescopic rod 702 to push the sealing push plate 704 downward.The water tank 307 is pressurized, and the water in the water tank 307 is pressurized and transported to the water injection cylinder 311 through the water suction pipe 308, so that the pressurized water assists in pushing the piston 319 to move, and then assists in the movement of the push rod 312 and the L-shaped transmission rod 310, and then assists in driving the inverted U-shaped frame 301 to slide on the photovoltaic panel 107, thereby preventing the dust on the photovoltaic panel 107 from being thick or snow on the photovoltaic panel 107 from hindering the sliding of the inverted U-shaped frame 301 and the water spraying of the water outlet 302 from cleaning the dust or snow on the photovoltaic panel 107, thereby cleaning the dust on the surface of the photovoltaic panel 107 and cleaning the snow on the photovoltaic panel 107 at the same time.
