Description

A photovoltaic platform for sandy wasteland Technical Field

[0001] This application relates to the field of photovoltaic panel technology, and in particular to a photovoltaic platform for desert land. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels (modules), a controller, and an inverter, with the main components being electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as a power controller, this forms a photovoltaic power generation device. It offers advantages such as no risk of depletion, safety and reliability, no noise or pollution emissions, and is not limited by resource distribution. It can utilize the advantages of building rooftops, for example, in areas without electricity or with complex terrain. It can generate and supply electricity locally without consuming fuel or erecting transmission lines, and offers high energy quality. It plays a role in saving and reusing resources and is widely used on rooftops, on water, and in desert areas.

[0003] The photovoltaic panel mentioned in the existing Chinese patent (authorization announcement number: CN220457318U) includes a frame mounted on a purlin of a mounting frame. It also includes a limiting plate and a clamping assembly. The limiting plate is fixedly mounted on the frame, and the clamping assembly is located below the limiting plate and connected to the frame. The clamping assembly is used to fix the purlin between the clamping assembly and the limiting plate. This utility model can initially fix the photovoltaic panel during installation, saving labor costs and improving work efficiency.

[0004] When existing photovoltaic (PV) platforms are located in sandy wastelands, dust prevention measures are rarely taken to avoid obstructing the PV panels. However, sandy wastelands contain a lot of sand and dust, which are often blown by the wind and adhere to the PV panels during use. Over time, the accumulation of sand and dust on the PV panels blocks solar radiation, reduces the reception of effective light spots, and not only blocks the entry of sunlight but also absorbs some sunlight and converts it into heat energy, causing the temperature of the PV modules to rise. This affects the absorption of solar energy by the PV panels and their normal use. It is inconvenient to require operators to bring cleaning equipment to the PV platform and install it on the platform to clean the PV panels. Summary of the Invention

[0005] The purpose of this application is to address the long-standing problem that excessive accumulation of sand and dust on photovoltaic panels affects their absorption of solar energy and their normal use. It also addresses the inconvenience of requiring workers to carry cleaning equipment to the photovoltaic platform and install it there, thus hindering the panel's cleaning process. This application provides a photovoltaic platform for sandy wastelands.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A photovoltaic platform for desert land includes a column, a connecting bracket fixed to the upper end of the column, a photovoltaic panel body installed on the connecting bracket, the photovoltaic panels body being arranged in a rectangular array, a cleaning mechanism provided on the connecting bracket, the cleaning mechanism including a connecting column installed on the photovoltaic panel body, a cleaning brush fixed on the connecting column, the cleaning brush contacting the photovoltaic panel body, and a driving structure provided on the connecting bracket for driving the cleaning brush to move.

[0008] By adopting the above technical solution, when the photovoltaic platform is put into use, the columns and connecting brackets are installed at designated locations in the sandy wasteland, and then the photovoltaic panels are installed and the corresponding lines are connected. During the use of the photovoltaic platform, the photovoltaic panels absorb sunlight and convert solar energy into electrical energy, realizing resource utilization. During the long-term use of the photovoltaic panels, when there is a lot of sand and dust attached to the photovoltaic panels, the drive structure drives the cleaning brush to move, thereby cleaning the photovoltaic panels. The cleaning effect is good, and no manual cleaning is required, improving convenience.

[0009] Furthermore, the drive structure includes a mounting plate fixed on a connecting bracket, two symmetrically arranged mounting blocks are fixed on the mounting plate, a drive motor is fixed on the mounting block, a bidirectional lead screw is fixed at the output end of the drive motor, the bidirectional lead screw is rotatably connected to the mounting block, a moving block is rotatably connected at the end of the connecting column, a ball nut is fixed inside the moving block, and the ball nut is slidably sleeved on the bidirectional lead screw.

[0010] By adopting the above technical solution, the drive motor operates, driving the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the ball nut to be stressed, which in turn causes the moving block to be stressed. Under the action of the ball nut, the moving block reciprocates on the bidirectional lead screw, thereby driving the connecting column to move. When the connecting column moves, it drives the cleaning brush to move reciprocally. During the movement of the cleaning brush, it is always in contact with the photovoltaic panel body, thereby cleaning off the sand and dust attached to the photovoltaic panel body, achieving a good cleaning effect and eliminating the need for manual cleaning.

[0011] Furthermore, two symmetrically arranged mounting blocks are fixed on the connecting bracket. A controller is fixed on the side of the mounting block and is electrically connected to the drive motor. A guide rod is fixed between the two mounting blocks. A guide block is rotatably connected to the end of the connecting column away from the moving block, and the guide block is slidably sleeved on the guide rod.

[0012] By adopting the above technical solution, the drive motor can be activated by sending a signal to the controller remotely, and the cleaning work can be completed without the need for on-site personnel. When the drive motor is working, the guide block and guide rod play a guiding and limiting role, so that the connecting column can move smoothly, which is more conducive to cleaning the photovoltaic panel body.

[0013] Furthermore, a transmission gear is fixed on the connecting column, and a transmission rack is fixed on the upper end of the mounting plate, wherein the transmission gear meshes with the transmission rack.

[0014] By adopting the above technical solution, during the movement of the cleaning brush, the transmission gear follows the movement of the connecting column. At this time, the transmission gear is restricted by the transmission rack and thus rotates. The rotation of the transmission gear causes the connecting column to rotate, which in turn drives the cleaning brush to rotate. By rotating the cleaning brush, the cleaning effect on the photovoltaic panel body can be improved, making the cleaning more thorough.

[0015] Furthermore, a collection box is fixed to the lower end of the mounting plate, a cover plate is fixed to the side of the collection box, ventilation holes are provided on the cover plate, a corrugated hose is fixed to the collection box, the corrugated hose is fixedly connected to the moving block, a guide pipe is fixed to the moving block, and the guide pipe, the corrugated hose, and the collection box are all interconnected.

[0016] By adopting the above technical solution, during the cleaning process of the photovoltaic panel, sand and dust enter the inside of the guide pipe, then enter the inside of the corrugated hose, and finally enter the collection box, thereby collecting the sand and dust, improving the cleaning effect of sand and dust, reducing the scattering of sand and dust, and reducing the re-falling of sand and dust on the photovoltaic panel.

[0017] Furthermore, a collection net is fixed inside the collection box, and a drive shaft is rotatably connected inside the collection box. A fan blade is fixed on the drive shaft, and the collection net is located above the fan blade.

[0018] By adopting the above technical solution, the drive shaft rotates to drive the fan blades to rotate, and the rotation of the fan blades generates suction, which can absorb sand and dust. The sand and dust that enter the collection box will fall onto the collection net, realizing the collection of sand and dust, reducing the scattering of sand and dust, improving the cleaning effect, and the rotation of multiple fan blades has a large suction force, which improves the collection effect.

[0019] Furthermore, transmission wheels are fixed on both the drive shaft and the output end of the drive motor, and the two transmission wheels are connected by a transmission belt.

[0020] By adopting the above technical solution, when the drive motor rotates, the transmission wheel at the output end of the drive motor rotates accordingly, and drives the transmission belt to rotate, thereby driving the transmission wheel on the drive shaft to rotate, so that the drive shaft rotates, and the transmission wheel and the transmission belt work together to perform the transmission function.

[0021] Furthermore, several diversion tubes are fixed on the guide tube, and the diversion tubes are arranged in a straight line array. A horn tube is fixed at the end of each diversion tube away from the guide tube.

[0022] By adopting the above technical solution, when collecting sand and dust, the diversion pipe and the horn pipe move together with the connecting column. The range of sand and dust collection can be increased through multiple diversion pipes and multiple horn pipes, thereby improving the collection effect of sand and dust and realizing real-time collection of sand and dust.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] When cleaning of photovoltaic panels is required, a signal is sent to the controller via remote control. The controller then controls the drive motor to rotate the bidirectional lead screw. As the lead screw rotates, the moving block is subjected to force and is restricted and guided by the guide block and guide rod, causing the moving block to move the connecting column. This allows the cleaning brush to wipe the photovoltaic panel body, removing sand and dust adhering to the surface. Simultaneously, as the connecting column moves, the transmission gear on the connecting column is restricted by the transmission rack on the mounting plate, causing the connecting column to drive the cleaning brush to rotate. The rotation of the cleaning brush improves the cleaning effect of sand and dust on the surface of the photovoltaic panel. The rotary reciprocating cleaning brush cleans the surface of the photovoltaic panel, resulting in a good cleaning effect and convenient cleaning. Furthermore, the remote control eliminates the need to transport and install cleaning equipment each time, improving convenience.

[0025] In this application, when the drive motor drives the cleaning brush to clean the photovoltaic panel, the transmission wheel on the output end of the drive motor rotates accordingly, and under the action of the transmission belt, it drives the transmission wheel on the drive shaft to rotate, thereby causing the drive shaft to rotate. When the drive shaft rotates, the fan blades follow the transmission, thereby generating suction. During the cleaning process of the cleaning brush cleaning sand and dust on the photovoltaic panel, the cleaned sand and dust will enter the inside of the horn tube due to the suction of the fan blades, and then enter the inside of the diversion pipe through the horn tube, and then enter the inside of the guide pipe through the diversion pipe, and then enter the corrugated hose. Finally, it enters the inside of the collection box through the corrugated hose and falls onto the collection net, thus realizing the collection of sand and dust. By collecting sand and dust, the cleaning effect of the photovoltaic panel can be further improved, and the sand and dust cleaned by the cleaning brush can be reduced from re-adhering to the photovoltaic panel.

[0026] In this application, when the cleaning brush moves to clean the photovoltaic panel, it will drive the guide pipe, the diversion pipe, and the horn pipe to move together. As the cleaning brush sweeps the sand and dust off the photovoltaic panel, it can collect them in time, thereby achieving real-time collection of sand and dust, reducing the dispersion of sand and dust, and improving the collection effect. At the same time, by setting multiple evenly distributed diversion pipes and multiple horn pipes, the collection range of sand and dust can be increased, reducing the dispersion of sand and dust, and improving the collection effect.

[0035] The present application will be further described in detail below with reference to Figures 1-6.

[0036] This application discloses a photovoltaic platform for desert land.

[0037] Referring to Figures 1-3, a photovoltaic platform for sandy wasteland includes a column 1, a connecting bracket 2 fixed at the upper end of the column 1, a photovoltaic panel body 3 installed on the connecting bracket 2, the photovoltaic panel bodies 3 being arranged in a rectangular array, and a cleaning mechanism being provided on the connecting bracket 2.

[0038] When installing the photovoltaic platform, the support column 1 is installed in the designated location, then the connecting bracket 2 is connected to the support column 1. Next, the photovoltaic panels 3 are installed sequentially on the connecting bracket 2. Finally, the corresponding transmission lines are connected, and the platform is ready for use. During operation, the photovoltaic platform absorbs sunlight, converts solar energy into electrical energy, and stores this energy using an energy storage device, thus enabling resource reuse. Over long-term use, the surface of the photovoltaic panels 3 will accumulate a significant amount of sand and dust. A cleaning mechanism can effectively remove this sand and dust, achieving a thorough clean without requiring on-site personnel, thus improving convenience and promoting the long-term use of the photovoltaic platform.

[0039] Referring to Figures 3-5, the cleaning structure includes a connecting column 26 installed on the photovoltaic panel body 3, a cleaning brush 6 fixed on the connecting column 26, the cleaning brush 6 being in contact with the photovoltaic panel body 3, and a driving structure for driving the cleaning brush 6 to move on the connecting bracket 2.

[0040] The drive structure includes a mounting plate 4 fixed on the connecting bracket 2. Two symmetrically arranged mounting blocks 5 are fixed on the mounting plate 4. A drive motor 7 is fixed on the mounting block 5. A bidirectional lead screw 8 is fixed at the output end of the drive motor 7. The bidirectional lead screw 8 is rotatably connected to the mounting block 5. A movable block 25 is rotatably connected at the end of the connecting column 26. A ball nut is fixed inside the movable block 25. The ball nut is slidably sleeved on the bidirectional lead screw 8.

[0041] In addition, two symmetrically arranged mounting blocks 9 are fixed on the connecting bracket 2. A controller 27 is fixed on the side of the mounting block. The controller 27 is electrically connected to the drive motor 7. A guide rod 10 is fixed between the two mounting blocks 9. A guide block 11 is rotatably connected to the end of the connecting column 26 away from the moving block 25. The guide block 11 is slidably sleeved on the guide rod 10.

[0042] Furthermore, a transmission gear 12 is fixed on the connecting column 26, and a transmission rack 13 is fixed on the upper end of the mounting plate 4. The transmission gear 12 meshes with the transmission rack 13.

[0043] When it is necessary to clean the photovoltaic panel body 3, a signal is sent to the controller 27 via remote control. The controller 27 controls the drive motor 7 to work, which drives the bidirectional lead screw 8 to rotate. When the bidirectional lead screw 8 rotates, the moving block 25 is subjected to force and is restricted and guided by the guide block 11 and the guide rod 10, so that the moving block 25 drives the connecting column 26 to move. When the connecting column 26 moves, it drives the cleaning brush 6 to move. The cleaning brush 6 is always in contact with the photovoltaic panel body 3, so that the cleaning brush 6 wipes the photovoltaic panel body 3 and removes the sand and dust attached to the surface of the photovoltaic panel. Meanwhile, as the connecting column 26 moves, the transmission gear 12 on the connecting column 26 is restricted by the transmission rack 13 on the mounting plate 4 and thus rotates. When the transmission gear 12 rotates, it drives the connecting column 26 to rotate, which in turn drives the cleaning brush 6 to rotate. By rotating the cleaning brush 6, the cleaning effect on the surface of the photovoltaic panel body 3, such as sand and dust, can be improved. After the moving block 25 moves to one end of the reciprocating screw, it will automatically move back, thereby driving the cleaning brush 6 to perform reciprocating cleaning on the surface of the photovoltaic panel body 3. The cleaning mechanism cleans the photovoltaic panel body 3, and the overall cleaning effect is good. The cleaning is also convenient, and there is no need to transport and install the cleaning equipment every time it is cleaned, which improves convenience.

[0044] Referring to Figures 2 and 6, a collection box 14 is fixed to the lower end of the mounting plate 4, a cover plate 15 is fixed to the side of the collection box 14, a ventilation hole is provided on the cover plate 15, a corrugated hose 19 is fixed to the collection box 14, the corrugated hose 19 is fixedly connected to the moving block 25, a guide pipe 20 is fixed to the moving block 25, and the guide pipe 20, the corrugated hose 19, and the collection box 14 are all interconnected.

[0045] The collection box 14 has a collection net 18 fixed inside, and a drive shaft 16 is rotatably connected inside the collection box 14. A fan blade 17 is fixed on the drive shaft 16, and the collection net 18 is located above the fan blade 17.

[0046] In addition, transmission wheels 21 are fixed on both the drive shaft 16 and the output end of the drive motor 7, and the two transmission wheels 21 are connected by a transmission belt 22.

[0047] Furthermore, several diversion pipes 23 are fixed on the guide pipe 20. The diversion pipes 23 are arranged in a straight line array, and a horn pipe 24 is fixed at the end of the diversion pipe 23 away from the guide pipe 20.

[0048] When the drive motor 7 moves the cleaning brush 6, the transmission wheel 21 on the output end of the drive motor 7 rotates accordingly, and under the action of the transmission belt 22, it drives the transmission wheel 21 on the drive shaft 16 to rotate, thereby causing the drive shaft 16 to rotate. When the drive shaft 16 rotates, the fan blade 17 follows the transmission, thereby generating suction. When the cleaning brush 6 cleans the sand and dust on the photovoltaic panel body 3, the cleaned sand and dust, under the influence of the suction of the fan blade 17, will enter the inside of the horn tube 24, enter the inside of the diversion pipe 23 through the horn tube 24, then enter the inside of the guide pipe 20 through the diversion pipe 23, and then enter the corrugated hose 19. After passing through the corrugated hose 19, it finally enters the inside of the collection box 14 and falls onto the collection net 18, thus collecting the sand and dust. By collecting the sand and dust, the cleaning effect of the photovoltaic panel can be further improved, and the sand and dust cleaned by the cleaning brush 6 can be reduced from re-adhering to the photovoltaic panel body 3. When the brush 6 moves to clean the photovoltaic panel body 3, it will move the guide pipe 20, the diversion pipe 23, and the horn pipe 24 together. While the cleaning brush 6 sweeps the sand and dust off the photovoltaic panel body 3, it can collect the sand and dust in time, thereby achieving real-time collection of sand and dust, reducing the scattering of sand and dust and improving the collection effect. By setting multiple diversion pipes 23 and multiple horn pipes 24, the range of sand and dust collection can be increased, reducing the scattering of sand and dust and improving the collection effect. In long-term use, when the operator reaches the photovoltaic platform to maintain some parts of the photovoltaic platform, the inside of the collection box 14 can be cleaned. During cleaning, the bolts used to fix the cover plate 15 are opened, and then the sand and dust on the collection net 18 are cleaned. After cleaning, the cover plate 15 is fixed to the collection box 14 with bolts. The cleaning process is relatively convenient and more conducive to long-term use.

[0049] Working principle: When installing the photovoltaic platform, install the column 1 in the designated position, then connect the connecting bracket 2 to the column 1, then install the photovoltaic panel body 3 on the connecting bracket 2 in sequence, and finally connect the corresponding transmission line. Then it can be put into use. During the use process, the photovoltaic platform absorbs sunlight, converts solar energy into electrical energy, and uses energy storage devices to store the electrical energy, thereby realizing the reuse of resources.

[0050] During long-term use of the photovoltaic platform, a significant amount of sand and dust will accumulate on the surface of the photovoltaic panel body 3. At this time, a signal is sent to the controller 27 via remote control. The controller 27 then controls the drive motor 7 to operate, causing it to rotate the bidirectional lead screw 8. When the bidirectional lead screw 8 rotates, the moving block 25 is subjected to force and is restricted and guided by the guide block 11 and guide rod 10, causing the moving block 25 to move the connecting column 26. As the connecting column 26 moves, it drives the cleaning brush 6 to move. Simultaneously, as the connecting column 26 moves, the transmission gear 12 on the connecting column 26 is subjected to force from the mounting plate 4. The transmission rack 13 restricts rotation, causing the connecting column 26 to drive the cleaning brush 6 to rotate. The rotation of the cleaning brush 6 cleans the surface of the photovoltaic panel body 3. After the moving block 25 moves to one end of the reciprocating screw, it will automatically move back, thereby driving the cleaning brush 6 to perform reciprocating cleaning on the surface of the photovoltaic panel. The rotating reciprocating cleaning brush 6 cleans the surface of the photovoltaic panel body 3. The overall cleaning effect is good, the cleaning process is convenient, and the background control method eliminates the need to transport and install cleaning equipment each time, improving convenience.

[0051] When the drive motor 7 moves the cleaning brush 6, the transmission wheel 21 on the output end of the drive motor 7 rotates accordingly, and under the action of the transmission belt 22, it drives the transmission wheel 21 on the drive shaft 16 to rotate, thereby causing the drive shaft 16 to rotate. When the drive shaft 16 rotates, the fan blade 17 follows the transmission, thereby generating suction. When the cleaning brush 6 cleans the sand and dust on the photovoltaic panel body 3, the cleaned sand and dust will enter the inside of the horn tube 24 under the influence of the suction of the fan blade 17, and then enter the inside of the diversion pipe 23 through the horn tube 24, and then enter the inside of the guide pipe 20 through the diversion pipe 23, and then enter the corrugated hose 19. After passing through the corrugated hose 19, it finally enters the inside of the collection box 14 and falls onto the collection net 18, thus realizing the collection of sand and dust. When the drive motor 7 is working, it can also drive the drive shaft 16 and other structures to rotate, thus realizing the collection function. By collecting sand and dust, the cleaning effect of the photovoltaic panel can be further improved, and the sand and dust cleaned by the cleaning brush 6 can be reduced to re-adhere to the photovoltaic panel body 3, thereby improving the use effect.

[0052] During long-term use, when operators arrive at the location of the photovoltaic platform to maintain some of its components, they can clean the inside of the collection box 14. During cleaning, the bolts used to fix the cover plate 15 are opened, and then the sand and dust on the collection net 18 are cleaned. After cleaning, the cover plate 15 is fixed to the collection box 14 with bolts.
