Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic support equipment and relates to a photovoltaic support. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that convert solar radiation into electrical energy. They are the core and most important part of a solar power generation system. Photovoltaic brackets are used to position and install photovoltaic panels. Most existing photovoltaic panel installation methods use screws to fix the photovoltaic panels on the photovoltaic mounting panels on the photovoltaic brackets. Under this fixing method, the process of disassembling and adjusting the photovoltaic panels is very cumbersome, time-consuming and labor-intensive, and there is a problem of unstable fixing. When the photovoltaic panels are subjected to strong winds and vibrations, the photovoltaic panels will shift or even fall off, causing damage to the photovoltaic panels.

[0003] In addition, most photovoltaic panels are installed outdoors. Due to the influence of the environment, a large amount of dust, dirt and other pollutants will accumulate on the surface of the photovoltaic panels, which will significantly reduce the light transmittance of the photovoltaic panels, resulting in a decrease in the amount of solar radiation irradiating the surface of the photovoltaic panels, thereby affecting the energy conversion efficiency of the entire photovoltaic system. Therefore, the photovoltaic panels need to be cleaned in time. At present, the cleaning work on the surface of photovoltaic panels mostly adopts manual cleaning methods, which requires a lot of manpower and has low cleaning efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a photovoltaic bracket in view of the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The photovoltaic panel is fixed on the photovoltaic positioning plate by the photovoltaic panel fixing assembly, which can ensure the close connection between the photovoltaic panel and the photovoltaic positioning plate. The photovoltaic panel is firmly fixed, which can effectively prevent the photovoltaic panel from being displaced or falling off due to wind pressure, vibration and the like, thereby enhancing the structural stability. The inclination angle of the photovoltaic panel can be adjusted by the photovoltaic angle adjustment mechanism, so that the photovoltaic panel can maintain the optimal inclination angle in different seasons and time periods, thereby maximizing the absorption of solar energy and improving the power generation efficiency. When the position of the sun changes, the rotation drive mechanism can drive the photovoltaic panel to rotate, and the rotation of the photovoltaic panel can adjust the angle in time to ensure that the photovoltaic panel is always facing the sun, avoiding light reflection or only absorbing part of the light energy, so as to maintain the optimal angle for receiving sunlight, ensuring that the photovoltaic panel can absorb solar energy more effectively and improve the power generation efficiency. The photovoltaic panel cleaning assembly on the top wall of the cleaning cover can clean the surface of the photovoltaic panel, and can effectively remove dirt and dust on the surface of the photovoltaic panel to maintain the cleanliness of the surface of the photovoltaic panel, reduce the erosion and damage of dirt to the photovoltaic panel material, thereby extending the service life of the photovoltaic panel.

[0008] In the above-mentioned photovoltaic bracket, the photovoltaic panel fixing assembly includes two side fixing blocks arranged on the photovoltaic positioning plate and respectively located on both sides of the photovoltaic panel. The side fixing blocks are vertically arranged and slidingly connected with the photovoltaic positioning plate. A side fixing drive assembly is provided between the two side fixing blocks on the same side. The side fixing drive assembly can synchronously drive the two side fixing blocks on the same side to approach and abut against the side of the photovoltaic panel or away from the photovoltaic panel. A downward pressing fixing assembly is also provided on the side fixing block.

[0009] The synchronous operation of the side fixing drive components on both sides of the photovoltaic panel can respectively drive the two side fixing blocks on both sides of the photovoltaic panel to slide toward the photovoltaic panel and press against the sides of the photovoltaic panel to clamp the photovoltaic panel.

[0012] In the above-mentioned photovoltaic bracket, the downward pressure fixing assembly includes a downward pressure fixing plate horizontally arranged on the side of the side fixing block near the photovoltaic panel, a downward pressure driving mechanism is provided between the side fixing block and the downward pressure fixing plate, which can drive the downward pressure fixing plate to move vertically back and forth along the side of the side fixing block, the downward pressure driving mechanism includes a downward pressure screw rod mounting groove arranged on the side fixing block and distributed vertically, a downward pressure screw rod is arranged in the downward pressure screw rod mounting groove, a downward pressure screw rod movable groove connected to the downward pressure screw rod mounting groove is opened on the side of the side fixing block near the photovoltaic panel, the downward pressure screw rod nut of the downward pressure screw rod is arranged in the downward pressure screw rod movable groove, the inner end of the downward pressure screw rod is rotatably connected to the inner side wall of the downward pressure screw rod movable groove, the outer end of the downward pressure screw rod is penetrated through the upper end of the side fixing block and is connected to the downward pressure driver, and the downward pressure screw rod nut is connected to the downward pressure fixing plate.

[0013] When the side fixing blocks on both sides of the photovoltaic panel clamp the photovoltaic panel, the downward pressure driver drives the downward pressure fixing plate to move vertically downward along the side of the side fixing block until it presses the side edge of the photovoltaic panel to apply a vertical downward force to the photovoltaic panel so that the photovoltaic panel is more firmly fixed on the photovoltaic positioning plate and can flexibly adapt to the installation requirements of photovoltaic panels of different specifications. The downward pressure fixing plate moves vertically upward along the side of the side fixing block to reset for disassembly of the photovoltaic panel, and the disassembly and assembly of the photovoltaic panel is efficient and convenient.

[0014] In the above-mentioned photovoltaic bracket, the rotation drive mechanism includes a rotation groove arranged on the mounting plate and adapted to the rotation adjustment plate, the bottom end of the rotation adjustment plate is provided with a rotation adjustment seat penetrating the mounting plate, the bracket body is provided with a rotation cavity adapted to the rotation adjustment seat, the outer periphery of the bottom end of the rotation adjustment seat is provided with a support plate distributed along the circumferential direction, a support frame is provided in the rotation cavity, the support frame is provided with a support groove rotatably connected to the support plate, the bottom end of the rotation cavity is provided with a base frame, the base frame is provided with a rotation driver, and the output end of the rotation driver is connected to the bottom end of the rotation adjustment seat.

[0015] The rotating groove at the top of the bracket body is adapted to the rotating adjustment plate for supporting the rotating adjustment plate, the supporting groove on the supporting frame in the rotating cavity is adapted to the supporting plate on the rotating adjustment seat for supporting the supporting plate, the rotating adjustment seat and the rotating adjustment plate are firmly fixed, and the operation of the rotating driver can drive the rotating adjustment seat to rotate and synchronously drive the rotating adjustment plate on the upper end of the rotating adjustment seat to rotate, so that the photovoltaic panel on the rotating adjustment plate rotates synchronously, and the rotation of the photovoltaic panel can adjust the angle in time to ensure that the photovoltaic panel is always facing the sun, avoiding light reflection or only absorbing part of the light energy, so as to maintain the best angle for receiving sunlight, ensuring that the photovoltaic panel can absorb solar energy more effectively and improve the power generation efficiency.

[0016] In the above-mentioned photovoltaic bracket, one side of the bottom end of the photovoltaic positioning plate is rotatably connected to the rotating adjustment plate through a first hinge seat, and the photovoltaic angle adjustment mechanism includes an adjustment driver arranged in the rotating adjustment seat, and the output end of the adjustment driver is passed through the rotating adjustment plate and is hinged to the bottom end of the photovoltaic positioning plate deviating from the rotation center through a second hinge seat.

[0017] The operation of the adjustment driver can drive the photovoltaic positioning plate to rotate around the hinged end of the first hinged seat, and can adjust the angle between the photovoltaic positioning plate and the rotating adjustment plate to adjust the inclination angle of the photovoltaic panel, so that the photovoltaic panel maintains the optimal inclination angle in different seasons and time periods, thereby maximizing the absorption of solar energy and improving power generation efficiency.

[0018] In the above-mentioned photovoltaic bracket, the photovoltaic positioning plate is made of a heat-conducting material, and a photovoltaic panel heat exchange component is arranged inside the photovoltaic positioning plate. The photovoltaic panel heat exchange component includes a heat exchange layer arranged in the photovoltaic positioning plate, and a serpentine heat exchange tube is distributed in the heat exchange layer. Both ends of the serpentine heat exchange tube respectively penetrate the photovoltaic positioning plate and form a heat exchange inlet and a heat exchange outlet. The heat exchange inlet and the heat exchange outlet are respectively connected to the heat exchange water tank arranged in the bracket body through a water inlet pipe and a water outlet pipe passing through the mounting plate, and a water inlet pump is arranged on the water inlet pipe.

[0019] The photovoltaic positioning plate is made of heat-conducting material. A large amount of heat generated during the operation of the photovoltaic panel can be conducted to the photovoltaic positioning plate. The operation of the water inlet pump allows the coolant in the heat exchange water tank to flow into the serpentine heat exchange tube from the heat exchange inlet of the serpentine heat exchange tube through the water inlet pipe. The coolant flows along the serpentine heat exchange tube to exchange heat inside the photovoltaic positioning plate. It can absorb the heat in the photovoltaic positioning plate and flow back into the heat exchange water tank through the heat exchange outlet and the water outlet pipe to form a heat exchange cycle, thereby conducting away a large amount of heat generated during the operation of the photovoltaic panel, effectively reducing the temperature of the photovoltaic panel, helping to maintain the photovoltaic panel operating within a suitable temperature range, maintaining its high power generation efficiency and extending the service life of the photovoltaic panel.

[0020] In the above-mentioned photovoltaic bracket, the photovoltaic panel cleaning component includes a cleaning positioning plate arranged on the top wall of the cleaning cover body, a cleaning positioning plate lifting structure is provided between the cleaning cover body and the cleaning positioning plate, a sliding plate is slidably connected to the cleaning positioning plate, a cleaning brush is provided at the bottom end of the sliding plate, a cleaning driving structure is provided between the cleaning positioning plate and the sliding plate, which can drive the sliding plate to reciprocate along the width direction of the cleaning positioning plate to clean the photovoltaic panel, and a liquid spray component is also provided on the inner wall of the cleaning cover body.

[0021] When the photovoltaic panels cannot work at night, the cleaning cover is closed, and the cleaning drive structure drives the cleaning brush at the bottom of the sliding plate to move back and forth on the surface of the photovoltaic panel along the width direction of the photovoltaic panel. The friction generated by the cleaning brush and the surface of the photovoltaic panel can effectively remove dust, dirt and other contaminants attached to the photovoltaic panel, and the reciprocating movement of the cleaning brush can cover the entire surface of the photovoltaic panel to ensure complete cleaning. The spray component can flush away dust and dirt on the surface of the photovoltaic panel by spraying water or cleaning liquid onto the surface of the photovoltaic panel. The mechanical wiping of the cleaning brush and the flushing action of the spray component act together on the surface of the photovoltaic panel to quickly remove dirt and dust. The cleaning positioning plate lifting structure can flexibly adjust the vertical height of the cleaning positioning plate to adapt to photovoltaic panels of different thicknesses, thereby improving adaptability and flexibility.

[0022] In the above-mentioned photovoltaic bracket, the cleaning drive structure includes two screw positioning grooves symmetrically arranged on the cleaning positioning plate and distributed along the width direction of the cleaning positioning plate. A cleaning screw is arranged in the screw positioning groove. The bottom end of the cleaning positioning plate is provided with a cleaning nut movable groove connected to the screw positioning groove. The inner end of the cleaning screw is rotatably connected to the inner side wall of the cleaning nut movable groove. The outer end of the cleaning screw is passed through the cleaning positioning plate and is connected to a cleaning driver. The cleaning screw nut of the cleaning screw is arranged in the cleaning nut movable groove and is connected to the top of the sliding plate.

[0023] The operation of the cleaning drive can drive the cleaning brush at the bottom of the sliding plate to reciprocate on the surface of the photovoltaic panel along the width direction of the photovoltaic panel. The reciprocating movement of the cleaning brush can cover the entire surface of the photovoltaic panel. The friction between the cleaning brush and the surface of the photovoltaic panel can effectively remove dust, dirt and other pollutants attached to the photovoltaic panel, and can clean the photovoltaic panel without omission. The photovoltaic panel can maintain the cleanliness of the surface, reduce the erosion and damage of dirt to the photovoltaic panel, thereby extending the service life of the photovoltaic panel. The cleaned photovoltaic panel can better absorb solar energy and convert it into electrical energy, thereby improving the energy conversion efficiency.

[0024] In the above-mentioned photovoltaic bracket, the liquid spray component includes a liquid spray body arranged on the inner wall of the cleaning cover body and distributed along the length direction of the inner wall. A liquid storage cavity is arranged in the liquid spray body. A plurality of liquid spray holes connected to the liquid storage cavity are arranged on the side wall of the liquid spray body near the photovoltaic panel. The plurality of liquid spray holes are evenly distributed along the length direction of the liquid spray body, and the liquid spray holes are inclined downward. A liquid inlet connected to the liquid storage cavity is arranged on the liquid spray body. The liquid inlet is connected to a water pump through a liquid inlet pipe passed through the cleaning cover body. The water pump is connected to an external water tank. A liquid spray body height adjustment structure is provided between the cleaning cover body and the liquid spray body.

[0025] The water pump runs to transport water or cleaning liquid from an external water tank to the liquid storage chamber of the liquid spray body. The liquid in the liquid storage chamber is sprayed out from the spray holes on the side wall of the liquid spray body under pressure and sprayed onto the surface of the photovoltaic panel to wash away dust and dirt on the surface of the photovoltaic panel. Combined with the mechanical wiping of the cleaning brush, the surface of the photovoltaic panel can be quickly removed by the liquid spray holes. The liquid spray holes are evenly distributed along the length of the liquid spray body to improve the uniformity of the liquid spray. The liquid spray holes are tilted downward so that the liquid sprayed from the liquid spray holes acts on the photovoltaic panel at a certain tilt angle. This tilt angle can generate a greater impact force when the liquid contacts the surface of the photovoltaic panel, which helps to remove dirt on the surface of the photovoltaic panel. The height adjustment structure of the liquid spray body can flexibly adjust the vertical height of the liquid spray body to adapt to photovoltaic panels of different thicknesses, thereby improving adaptability and flexibility.

[0026] Compared with the existing technology, the advantages of the present invention are: 1. The photovoltaic panel is firmly fixed on the photovoltaic positioning plate, the photovoltaic positioning plate can adapt to the installation requirements of photovoltaic panels of different specifications, and the photovoltaic panel is easy to disassemble and assemble. 2. The heat generated during the operation of the photovoltaic panel can be discharged in time, which helps to maintain the operation of the photovoltaic panel within a suitable temperature range and maintain its high power generation efficiency. 3. The inclination angle of the photovoltaic panel can be flexibly adjusted and can ensure that the photovoltaic panel is always facing the sun, so that the photovoltaic panel can maximize the absorption of solar energy and improve power generation efficiency. 4. By spraying water or cleaning liquid on the surface of the photovoltaic panel, the dust and dirt on the surface of the photovoltaic panel can be washed away, and combined with the mechanical wiping of the cleaning brush on the surface of the photovoltaic panel, dirt and dust can be quickly removed.

When the photovoltaic panel 4 cannot work at night, the opening and closing drive mechanism operates to close the cleaning cover 9, or the cleaning cover 9 is manually closed, and the photovoltaic panel cleaning assembly 10 on the top wall of the cleaning cover 9 operates to clean the surface of the photovoltaic panel 4.

[0040] The photovoltaic panel 4 is fixed on the photovoltaic positioning plate 3 by the photovoltaic panel fixing assembly 5, which can ensure the close connection between the photovoltaic panel 4 and the photovoltaic positioning plate 3. The photovoltaic panel 4 is firmly fixed, which can effectively prevent the photovoltaic panel 4 from being displaced or falling off due to wind pressure, vibration and the like, thereby enhancing the structural stability. The inclination angle of the photovoltaic panel 4 can be adjusted by the photovoltaic angle adjustment mechanism 8, so that the photovoltaic panel 4 can maintain the optimal inclination angle in different seasons and time periods, thereby maximizing the absorption of solar energy and improving the power generation efficiency. When the position of the sun changes, the rotation drive mechanism 7 can drive the photovoltaic panel 4 to rotate, and the rotation of the photovoltaic panel 4 can adjust the angle in time to ensure that the photovoltaic panel 4 always faces the sun, avoids light reflection or can only absorb part of the light energy, so as to maintain the optimal angle for receiving sunlight, ensure that the photovoltaic panel 4 can absorb solar energy more effectively, and improve the power generation efficiency.

[0041] Specifically, combined with Figure 1-Figure 4 As shown, the photovoltaic panel fixing assembly 5 includes two side fixing blocks 11 arranged on the photovoltaic positioning plate 3 and respectively located on both sides of the photovoltaic panel 4. The side fixing blocks 11 are vertically arranged and slidingly connected with the photovoltaic positioning plate 3. A side fixing driving assembly 12 is provided between the two side fixing blocks 11 on the same side. The side fixing driving assembly 12 can synchronously drive the two side fixing blocks 11 on the same side to approach and abut against the side of the photovoltaic panel 4 or away from the photovoltaic panel 4. A downward pressing fixing assembly 13 is also provided on the side fixing blocks 11.

[0043] When the side fixing blocks 11 on both sides of the photovoltaic panel 4 clamp the photovoltaic panel 4, the operation of the downward pressing fixing assembly 13 can apply a vertical downward force to the photovoltaic panel 4 so that the photovoltaic panel 4 is firmly fixed on the photovoltaic positioning plate 3, further strengthening the close connection between the photovoltaic panel 4 and the photovoltaic positioning plate 3. The photovoltaic panel 4 is firmly fixed, which can effectively prevent the photovoltaic panel 4 from being displaced or falling off due to wind pressure, vibration and the like, and enhance the structural stability. The side fixing blocks 11 and the downward pressing fixing assembly 13 are reset to complete the disassembly of the photovoltaic panel 4. The photovoltaic panel 4 is easy to disassemble and assemble, which improves the disassembly and assembly efficiency and reduces the maintenance cost and time cost.

[0044] Specifically, combined with Figure 2-Figure 4 As shown, the side fixed drive assembly 12 includes a fixed screw mounting groove 14 arranged on the photovoltaic positioning board 3 and distributed along the sliding direction of the side fixed block 11, a fixed screw 15 is arranged in the fixed screw mounting groove 14, and a fixed screw nut movable groove 16 connected to the fixed screw mounting groove 14 is opened on the photovoltaic positioning board 3, a fixed screw nut 17 of the fixed screw 15 is arranged in the fixed screw nut movable groove 16, the inner end of the fixed screw 15 is rotatably connected to the inner side wall of the fixed screw nut movable groove 16, the outer end of the fixed screw 15 is penetrated by the photovoltaic positioning board 3 and is connected to a fixed driver 18, and the fixed screw nut 17 is connected to the two side fixed blocks 11 on the same side through a synchronous connection structure 19.

[0045] The fixed drivers 18 on both sides operate synchronously and can respectively drive their respective fixed screws 15 to rotate. The fixed screw nuts 17 of the fixed screws 15 can reciprocate on the fixed screws 15 along the length direction of the fixed screws 15 and synchronously drive the two side fixed blocks 11 on the same side to approach or move away from the photovoltaic panel 4 through the synchronous connection structure 19, which are respectively used to clamp the photovoltaic panel 4 and reset it. The photovoltaic panel 4 is firmly fixed and easy to disassemble and assemble.

[0046] Specifically, combined with Figure 2 and Figure 3 As shown, the synchronous connection structure 19 includes a synchronous block 20 which is arranged on the photovoltaic positioning plate 3 and is slidably connected to the photovoltaic positioning plate 3. The bottom end of the synchronous block 20 is connected to the fixed screw nut 17 of the fixed screw 15. Synchronous drive rods 21 are respectively provided on both sides of the synchronous block 20. The two synchronous drive rods 21 are respectively connected to the side fixed blocks 11 on both sides.

[0048] Specifically, combined with Figure 2-Figure 4As shown, the pressing and fixing assembly 13 includes a pressing and fixing plate 22 horizontally arranged on the side of the side fixing block 11 near the photovoltaic panel 4, and a pressing driving mechanism 23 is provided between the side fixing block 11 and the pressing and fixing plate 22, which can drive the pressing and fixing plate 22 to move vertically back and forth along the side of the side fixing block 11. The pressing driving mechanism 23 includes a pressing screw rod mounting groove 24 arranged on the side fixing block 11 and distributed vertically, and a pressing screw rod 25 is arranged in the pressing screw rod mounting groove 24. A pressing screw nut movable groove 26 connected to the pressing screw rod mounting groove 24 is opened on the side of the side fixing block 11 near the photovoltaic panel 4, and a pressing screw nut 27 of the pressing screw rod 25 is arranged in the pressing screw nut movable groove 26, and the inner end of the pressing screw rod 25 is rotatably connected to the inner side wall of the pressing screw nut movable groove 26, and the outer end of the pressing screw rod 25 is penetrated through the upper end of the side fixing block 11 and is connected to a pressing driver 28, and the pressing screw nut 27 is connected to the pressing and fixing plate 22.

[0049] When the side fixing blocks 11 on both sides of the photovoltaic panel 4 clamp the photovoltaic panel 4, the downward pressure driver 28 can drive the downward pressure screw 25 to rotate, and the downward pressure screw nut 27 of the downward pressure screw 25 can reciprocate on the downward pressure screw 25 along the length direction of the downward pressure screw 25 and synchronously drive the downward pressure fixing plate 22 to reciprocate vertically along the side of the side fixing block 11. The downward pressure fixing plate 22 moves vertically downward along the side of the side fixing block 11 to press the side edge of the photovoltaic panel 4 to apply a vertical downward force to the photovoltaic panel 4 so that the photovoltaic panel 4 is more firmly fixed on the photovoltaic positioning plate 3, and can flexibly adapt to the installation requirements of photovoltaic panels 4 of different specifications. The downward pressure fixing plate 22 moves vertically upward along the side of the side fixing block 11 to reset for disassembly of the photovoltaic panel 4. The disassembly and assembly of the photovoltaic panel 4 is efficient and convenient.

[0050] Preferably, combined Figure 4 and Fig. 9 As shown, an anti-skid structure 29 is provided at the bottom end of the pressing and fixing plate 22 , and the anti-skid structure 29 includes a corrugated anti-skid protrusion 30 provided at the bottom end of the pressing and fixing plate 22 .

[0051] When the downward fixing plate 22 is pressed tightly against the side edge of the photovoltaic panel 4, the corrugated anti-slip protrusions 30 at the bottom end of the downward fixing plate 22 can increase the roughness of the contact surface, significantly improving the friction between the downward fixing plate 22 and the side edge of the photovoltaic panel 4. The increased friction helps to resist the sliding tendency under the action of external force, ensuring that the photovoltaic panel 4 can be firmly maintained in the predetermined position, thereby improving stability.

[0052] Preferably, combined Figure 2 and Figure 4 As shown, a sliding guide structure 31 is provided between the side fixing block 11 and the photovoltaic positioning plate 3. The sliding guide structure 31 includes a sliding guide groove 32 arranged on the photovoltaic positioning plate 3 and distributed along the sliding direction of the side fixing block 11. A guide slider 33 is provided at the bottom end of the side fixing block 11 and slides with the sliding guide groove 32.

[0053] When the side fixing block 11 slides on the photovoltaic positioning plate 3, the guide slider 33 at the bottom end of the side fixing block 11 slides in the sliding guide groove 32 on the photovoltaic positioning plate 3. The guide slider 33 can slide along the trajectory of the sliding guide groove 32, thereby playing a role of sliding guide and reducing the displacement and shaking of the side fixing block 11 during the sliding process, thereby improving the sliding stability of the side fixing block 11.

[0056] The rotation of the photovoltaic panel 4 can adjust the angle in time to ensure that the photovoltaic panel 4 always faces the sun, avoiding light reflection or only absorbing part of the light energy, so as to maintain the best angle for receiving sunlight, ensuring that the photovoltaic panel 4 can absorb solar energy more effectively and improve power generation efficiency.

[0057] Specifically, combined with Figure 1 As shown, one side of the bottom end of the photovoltaic positioning panel 3 is rotatably connected to the rotating adjustment panel 6 via a first hinge seat 42, and the photovoltaic angle adjustment mechanism 8 includes an adjustment driver 43 arranged in the rotating adjustment seat 35, and the output end of the adjustment driver 43 is passed through the rotating adjustment panel 6 and is hinged to the bottom end of the photovoltaic positioning panel 3 deviating from the rotation center through a second hinge seat 44.

[0058] The adjustment driver 43 operates to control the expansion and contraction of the output end of the adjustment driver 43, which can drive the photovoltaic positioning plate 3 to rotate around the hinge end of the first hinge seat 42, and can adjust the angle between the photovoltaic positioning plate 3 and the rotating adjustment plate 6 to adjust the inclination angle of the photovoltaic panel 4, so that the photovoltaic panel 4 maintains the optimal inclination angle in different seasons and time periods, thereby maximizing the absorption of solar energy and improving power generation efficiency.

[0059] Specifically, combined with Figure 3-Figure 5 As shown, the photovoltaic positioning plate 3 is made of a heat-conducting material, and a photovoltaic panel heat exchange component 45 is provided inside the photovoltaic positioning plate 3. The photovoltaic panel heat exchange component 45 includes a heat exchange layer 46 arranged in the photovoltaic positioning plate 3, and a serpentine heat exchange tube 47 is distributed in the heat exchange layer 46. Both ends of the serpentine heat exchange tube 47 respectively penetrate the photovoltaic positioning plate 3 and form a heat exchange inlet 48 and a heat exchange outlet 49. The heat exchange inlet 48 and the heat exchange outlet 49 are respectively connected to the heat exchange water tank arranged in the bracket body 1 through a water inlet pipe and a water outlet pipe passing through the mounting plate 2, and a water inlet pump is provided on the water inlet pipe.

[0060] The photovoltaic panel 4 is fixedly placed on the photovoltaic positioning plate 3, and the back of the photovoltaic panel 4 is in close contact with the surface of the photovoltaic positioning plate 3. The photovoltaic panel heat exchange component 45 in the photovoltaic positioning plate 3 can conduct away a large amount of heat generated during the operation of the photovoltaic panel 4, which can effectively reduce the temperature of the photovoltaic panel 4, help to maintain the photovoltaic panel 4 operating within a suitable temperature range, maintain its high power generation efficiency and extend the service life of the photovoltaic panel.

[0061] The photovoltaic positioning plate 3 is made of a heat-conducting material. A large amount of heat generated during the operation of the photovoltaic panel 4 can be conducted to the photovoltaic positioning plate 3. The operation of the water inlet pump allows the coolant in the water exchange tank to flow into the serpentine heat exchange tube 47 from the heat exchange inlet 48 of the serpentine heat exchange tube 47 through the water inlet pipe. The coolant flows along the serpentine heat exchange tube 47 inside the photovoltaic positioning plate 3 for heat exchange. It can absorb the heat in the photovoltaic positioning plate 3 and flow back into the water exchange tank through the heat exchange outlet 49 and the water outlet pipe to form a heat exchange cycle, thereby conducting away a large amount of heat generated during the operation of the photovoltaic panel 4, effectively reducing the temperature of the photovoltaic panel 4, helping to maintain the photovoltaic panel 4 operating within a suitable temperature range, maintaining its high power generation efficiency and extending the service life of the photovoltaic panel.

[0062] Specifically, combined with Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, the photovoltaic panel cleaning assembly 10 includes a cleaning positioning plate 50 arranged on the inner top wall of the cleaning cover body 9, a cleaning positioning plate lifting structure 51 is provided between the cleaning cover body 9 and the cleaning positioning plate 50, a sliding plate 52 is slidably connected to the cleaning positioning plate 50, a cleaning brush 53 is provided at the bottom end of the sliding plate 52, a cleaning driving structure 54 is provided between the cleaning positioning plate 50 and the sliding plate 52, which can drive the sliding plate 52 to reciprocate along the width direction of the cleaning positioning plate 50 to clean the photovoltaic panel 4, and a liquid spray assembly 55 is also provided on the inner wall of the cleaning cover body 9.

[0063] When the photovoltaic panel 4 cannot work at night, the cleaning cover 9 is closed, and the cleaning drive structure 54 between the cleaning positioning plate 50 and the sliding plate 52 drives the sliding plate 52 to slide back and forth on the cleaning positioning plate 50 so that the cleaning brush 53 at the bottom end of the sliding plate 52 moves back and forth on the surface of the photovoltaic panel 4 along the width direction of the photovoltaic panel 4. The friction force generated between the cleaning brush 53 and the surface of the photovoltaic panel 4 can effectively remove dust, dirt and other contaminants attached to the photovoltaic panel 4, and the reciprocating movement of the cleaning brush 53 can cover the entire surface of the photovoltaic panel 4 to ensure that no omissions are left.

[0064] The liquid spray component 55 can flush away dust and dirt on the surface of the photovoltaic panel 4 by spraying water or cleaning liquid onto the surface of the photovoltaic panel 4, and complement the mechanical wiping action of the cleaning brush 53. The mechanical wiping action of the cleaning brush 53 and the flushing action of the liquid spray component 55 act together on the surface of the photovoltaic panel 4 to quickly remove dirt and dust.

[0065] The cleaning positioning plate lifting structure 51 between the cleaning cover 9 and the cleaning positioning plate 50 can flexibly adjust the vertical height of the cleaning positioning plate 50 to adapt to photovoltaic panels 4 of different thicknesses, so as to improve adaptability and flexibility.

[0066] Specifically, combined with Figure 6-Figure 8 As shown, the cleaning positioning plate lifting structure 51 includes a lifting and adjusting driver 56 arranged on the top of the cleaning cover body 9, the output end of the lifting and adjusting driver 56 is passed through the inner top wall of the cleaning cover body 9 and is connected to the top of the cleaning positioning plate 50, and a lifting support assembly 57 is also provided between the inner top wall of the cleaning cover body 9 and the cleaning positioning plate 50.

[0067] The lifting and adjusting driver 56 controls the operation of the lifting and adjusting driver 56. The output end of the lifting and adjusting driver 56 can be extended and retracted to drive the cleaning positioning plate 50 to vertically lift and lower in the cleaning cover 9 to flexibly adjust the vertical height of the cleaning positioning plate 50 to adapt to photovoltaic panels 4 of different thicknesses, thereby improving adaptability and flexibility.

[0068] The lifting support assembly 57 between the inner top wall of the cleaning cover 9 and the cleaning positioning plate 50 serves to support the cleaning positioning plate 50 and to provide vertical guidance when the cleaning positioning plate 50 is vertically lifted or lowered to adjust its height.

[0069] Specifically, combined with Figure 7 and Figure 8 As shown, the lifting support assembly 57 includes a plurality of telescopic support rods 58 vertically arranged between the inner top wall of the cleaning cover body 9 and the cleaning positioning plate 50, one end of the telescopic support rod 58 is connected to the inner top wall of the cleaning cover body 9, and the other end is connected to the top of the cleaning positioning plate 50.

[0070] A plurality of telescopic support rods 58 vertically arranged between the inner top wall of the cleaning cover 9 and the cleaning positioning plate 50 are used to support the cleaning positioning plate 50, and play a role of stable support. In the process of vertical lifting of the cleaning positioning plate 50, the telescopic support rods 58 are followed to extend and retract, and play a role of vertical guidance, which can reduce the displacement and shaking of the cleaning positioning plate 50 during the vertical lifting process, and improve the stability of the lifting of the cleaning positioning plate 50.

[0071] Specifically, combined with Figure 7 and Figure 8 As shown, the cleaning drive structure 54 includes two screw positioning grooves 59 symmetrically arranged on the cleaning positioning plate 50 and distributed along the width direction of the cleaning positioning plate 50. A cleaning screw 60 is arranged in the screw positioning groove 59. A cleaning screw nut movable groove 61 connected to the screw positioning groove 59 is opened at the bottom end of the cleaning positioning plate 50. The inner end of the cleaning screw 60 is rotatably connected to the inner side wall of the cleaning screw nut movable groove 61. The outer end of the cleaning screw 60 is passed through the cleaning positioning plate 50 and is connected to a cleaning driver 62. The cleaning screw nut 63 of the cleaning screw 60 is arranged in the cleaning screw nut movable groove 61 and is connected to the top of the sliding plate 52.

[0072] The operation of the cleaning driver 62 can drive the cleaning screw 60 to rotate, and the cleaning screw nut 63 of the cleaning screw 60 can reciprocate on the cleaning screw 60 along the length direction of the cleaning screw 60 and synchronously drive the cleaning brush 53 at the bottom end of the sliding plate 52 to reciprocate on the surface of the photovoltaic panel 4 along the width direction of the photovoltaic panel 4. The reciprocating movement of the cleaning brush 53 can cover the entire surface of the photovoltaic panel 4. The friction generated by the cleaning brush 53 and the surface of the photovoltaic panel 4 can effectively remove dust, dirt and other pollutants attached to the photovoltaic panel 4, and can clean the photovoltaic panel 4 without omission. The photovoltaic panel 4 can maintain the cleanliness of the surface, reduce the erosion and damage of dirt to the photovoltaic panel 4, thereby extending the service life of the photovoltaic panel 4. The cleaned photovoltaic panel 4 can better absorb solar energy and convert it into electrical energy, thereby improving the energy conversion efficiency.

[0073] Preferably, combined Figure 6 and Figure 8As shown, a sliding plate guide structure 64 is provided between the sliding plate 52 and the cleaning positioning plate 50. The sliding plate guide structure 64 includes a guide sliding groove 65 arranged at the bottom end of the cleaning positioning plate 50 and distributed along the width direction of the cleaning positioning plate 50. The guide sliding groove 65 is located in the middle position of the two screw positioning grooves 59. A guide sliding block 66 is provided at the top of the sliding plate 52 and slides with the guide sliding groove 65.

[0074] When the sliding plate 52 slides on the cleaning positioning plate 50, the guide sliding block 66 at the top of the sliding plate 52 slides in the guide sliding groove 65 on the cleaning positioning plate 50. The guide sliding block 66 can slide along the trajectory of the guide sliding groove 65, thereby playing a role of sliding guide and reducing the displacement and shaking of the sliding plate 52 during the sliding process, thereby improving the sliding stability of the sliding plate 52.

[0075] Specifically, combined with Figure 7 and Figure 8 As shown, the liquid spray component 55 includes a liquid spray body 67 arranged on the inner wall of the cleaning cover body 9 and distributed along the length direction of the inner wall. A liquid storage cavity 68 is arranged in the liquid spray body 67. A plurality of liquid spray holes 69 connected to the liquid storage cavity 68 are arranged on the side wall of the liquid spray body 67 near the photovoltaic panel 4. The plurality of liquid spray holes 69 are evenly distributed along the length direction of the liquid spray body 67, and the liquid spray holes 69 are inclined downward. A liquid inlet connected to the liquid storage cavity 68 is provided on the liquid spray body 67. The liquid inlet is connected to a water pump through a liquid inlet pipe passed through the cleaning cover body 9. The water pump is connected to an external water tank. A liquid spray body height adjustment structure 70 is provided between the cleaning cover body 9 and the liquid spray body 67.

[0076] The water pump runs to transport water or cleaning liquid from the external water tank to the liquid storage chamber 68 of the liquid sprayer body 67. The liquid in the liquid storage chamber 68 is sprayed out from the liquid spray hole 69 on the side wall of the liquid sprayer body 67 under pressure and sprayed onto the surface of the photovoltaic panel 4 to wash away dust and dirt on the surface of the photovoltaic panel 4. Combined with the mechanical wiping of the cleaning brush 53, the liquid acts on the surface of the photovoltaic panel 4 to quickly remove dirt and dust.

[0077] The liquid spray holes 69 are evenly distributed along the length direction of the liquid spray body 67, which can improve the uniformity of the liquid spray. The liquid spray holes 69 are tilted downward so that the liquid sprayed from the liquid spray holes 69 acts on the photovoltaic panel 4 with a certain tilt angle. This tilt angle can make the liquid produce a greater impact force when it contacts the surface of the photovoltaic panel 4, which helps to remove dirt on the surface of the photovoltaic panel 4. The tilted liquid spray can make the liquid more evenly distributed on the surface of the photovoltaic panel 4, avoiding excessive or insufficient liquid in local areas, which helps to improve the cleaning efficiency.

[0078] The liquid spray body height adjustment structure 70 between the cleaning cover body 9 and the liquid spray body 67 can flexibly adjust the vertical height of the liquid spray body 67 to adapt to photovoltaic panels 4 of different thicknesses, thereby improving adaptability and flexibility.

[0079] Specifically, combined with Figure 7 and Figure 8 As shown, the height adjustment structure 70 of the liquid spray body includes a height adjustment groove 71 arranged on the inner wall of the cleaning cover body 9, and the liquid spray body 67 is vertically slidably connected in the height adjustment groove 71. A height adjustment driver 72 is provided in the cleaning cover body 9. The output end of the height adjustment driver 72 is passed through the top of the height adjustment groove 71 and is connected to the top of the liquid spray body 67. The cleaning cover body 9 is provided with a liquid inlet pipe adjustment groove adapted to the liquid inlet pipe.

[0080] The height adjustment driver 72 operates to control the output end of the height adjustment driver 72 to extend and retract, which can drive the liquid spray body 67 to vertically rise and fall in the height adjustment slot 71 to flexibly adjust the vertical height of the liquid spray body 67 to adapt to photovoltaic panels 4 of different thicknesses, thereby improving adaptability and flexibility. When the liquid spray body 67 is adjusted in vertical height, the liquid inlet pipe slides vertically in the liquid inlet pipe adjustment slot, and the liquid inlet pipe adjustment slot plays a role of giving way to the liquid inlet pipe.

[0081] The working principle of the present invention is as follows: the fixed drivers 18 on both sides of the photovoltaic panel 4 are synchronously operated to drive the two side fixed blocks 11 on both sides to slide toward the photovoltaic panel 4 and press against the side of the photovoltaic panel 4 to clamp the photovoltaic panel 4 through the synchronous connection structure 19, and then the pressing driver 28 is operated to drive the pressing fixing plate 22 to move vertically downward to press the side edge of the photovoltaic panel 4 to apply a vertical downward force to the photovoltaic panel 4 so that the photovoltaic panel 4 is more firmly fixed on the photovoltaic positioning plate 3;

[0082] The rotation driver 41 drives the rotation adjustment seat 35 to rotate and synchronously drives the rotation adjustment plate 6 on the upper end of the rotation adjustment seat 35 to rotate, so that the photovoltaic panel 4 on the rotation adjustment plate 6 rotates synchronously and adjusts the angle in time to ensure that the photovoltaic panel 4 always faces the sun. The adjustment driver 43 drives the photovoltaic positioning plate 3 to rotate around the hinged end of the first hinge seat 42 to adjust the tilt angle of the photovoltaic panel 4, so that the photovoltaic panel 4 maintains the optimal tilt angle in different seasons and time periods;

[0083] A large amount of heat generated during the operation of the photovoltaic panel 4 can be transferred to the photovoltaic positioning panel 3. The operation of the water inlet pump allows the coolant in the heat exchange water tank to flow into the serpentine heat exchange tube 47 from the heat exchange inlet 48 of the serpentine heat exchange tube 47 through the water inlet pipe. The coolant flows along the serpentine heat exchange tube 47 inside the photovoltaic positioning panel 3 for heat exchange, and can absorb the heat in the photovoltaic positioning panel 3 and flow back into the heat exchange water tank through the heat exchange outlet 49 and the water outlet pipe to form a heat exchange cycle.

[0084] When the photovoltaic panel 4 cannot work at night, the cleaning cover 9 is closed, and the cleaning driver 62 drives the cleaning brush 53 at the bottom of the sliding plate 52 to move back and forth on the surface of the photovoltaic panel 4 along the width direction of the photovoltaic panel 4. The water pump runs to transport the water or cleaning liquid in the external water tank to the liquid storage chamber 68 of the liquid spraying body 67. The liquid in the liquid storage chamber 68 is sprayed out from the liquid spraying hole 69 on the side wall of the liquid spraying body 67 under the action of pressure, and sprayed onto the surface of the photovoltaic panel 4. Combined with the mechanical wiping of the cleaning brush 53, it acts on the surface of the photovoltaic panel 4 to quickly remove dirt and dust.

[0085] The height adjustment driver 72 can drive the liquid spray body 67 to vertically rise and fall in the height adjustment groove 71, and the lifting adjustment driver 56 can drive the cleaning positioning plate 50 to vertically rise and fall in the cleaning cover body to flexibly adapt to photovoltaic panels 4 of different thicknesses.
