[0014] The present invention provides an easily installable photovoltaic power generation device, having the following beneficial effects: (1) In this invention, the scraper rod moves to clean the impurities falling on the photovoltaic panel, keeping the photovoltaic panel with a high light transmittance, allowing more sunlight to pass through and be converted into electric energy, thereby improving the power generation efficiency. At the same time, it avoids the hot spot effect caused by pollutant occlusion, extends the service life of the photovoltaic panel, and reduces the maintenance workload and cost caused by problems such as corrosion. By moving the limit block to disengage from the reciprocating lead screw, the restriction on the reciprocating lead screw is released, ensuring that the photovoltaic panel can be cleaned only at a certain angle, making the impurities easier to be cleaned and easier to slide along the adjusted angle of the photovoltaic panel, avoiding incomplete cleaning of impurities when the photovoltaic panel is flat.

[0015] (2) In this invention, when the photovoltaic panel adjusts in one direction, the support rod moves downward to reinforce the support of the bracket by the support rod, preventing it from tipping due to external forces, ensuring the safe operation of the photovoltaic power generation device, reducing the risk of structural damage caused by extreme weather, and improving the durability of the photovoltaic power generation device. At the same time, the support rod can share part of the weight and external forces of the photovoltaic panel, making the force on the connecting components and rotating components more uniform, reducing the degree of wear, thereby extending the service life of these components and reducing the maintenance cost and replacement frequency of the photovoltaic power generation device.

[0016] (3) In this invention, the semi-circular ring moves into contact with the rotating shaft, applying frictional force to the rotating shaft, making the adjustment process smoother and more precise, preventing small deviations in the angle of the photovoltaic panel due to external factors, ensuring that the photovoltaic panel is always at the optimal power generation angle, maintaining a stable power generation efficiency, and at the same time preventing the photovoltaic panel from rotating or swinging randomly due to excessive wind force, reducing the risk of equipment damage, and enhancing the reliability of the photovoltaic power generation device in harsh environments.

[0017] (4) In this invention, the water in the water tank is sprayed out from the nozzle through the water pipe by the water pump. For some stains with strong viscosity or tight adhesion, the impact force and soaking effect of the water can soften and remove them. Compared with simple dry wiping or scraping, the cleaning effect is more thorough, and it can better restore the light transmittance of the photovoltaic panel. By restricting the pump switch to be released only when the photovoltaic panel is adjusted to a certain angle, it helps the water, cleaning liquid, and the stains washed down during the cleaning process to flow more smoothly from the surface of the photovoltaic panel under the action of gravity, avoiding residue. This can reduce the possibility of water stains and stain residues, clean the photovoltaic panel more thoroughly, and thus better ensure its light transmittance and power generation efficiency.

At the same time, the hot spot effect caused by the blockage of pollutants is avoided, the service life of the photovoltaic panel 4 is extended, and the maintenance workload and cost caused by problems such as corrosion are reduced.

[0022] The cleaning device further includes a fixed rail 9, a first elastic telescopic rod 10, a second elastic telescopic rod 11 and a contact rod 12. The fixed rail 9 is fixedly installed on the top of the bottom plate 91. The first elastic telescopic rod 10 is rotatably installed on the top of the bottom plate 91. One end of the second elastic telescopic rod 11 is rotatably installed at the fixed end of the first elastic telescopic rod 10. The other end of the second elastic telescopic rod 11 is slidably installed inside the fixed rail 9. The contact rod 12 is fixedly installed on the top of the first elastic telescopic rod 10. The surfaces of the push rod 13 and the limit block 15 in contact with each other are both set as inclined surfaces, and the inclined surfaces are provided to ensure that the push rod 13 can smoothly push the limit block 15 when moving.

[0023] During the operation of this embodiment: After the staff installs the photovoltaic power generation device at the designated position, the staff confirms that the installation is correct and then starts the operation. The staff starts Motor 1 2, causing Motor 1 2 to drive the rotating shaft 3 to start rotating. The rotation of the rotating shaft 3 drives the photovoltaic panel 4 to start rotating. The rotation of the photovoltaic panel 4 makes the sunny side always face the sun, allowing the photovoltaic panel 4 to receive more solar radiation energy rate. Under the conditions of the same photovoltaic panel 4 area and lighting time, more electricity can be generated. When the photovoltaic panel 4 rotates to adjust the angle, it contacts and pushes one end of the contact rod 12. The movement of the contact rod 12 contacts and pushes the push rod 13 to start moving. The movement of the push rod 13 contacts and pushes the limit block 15 to start moving downward along the direction of the slide rail 14. The movement of the limit block 15 disengages from the reciprocating lead screw 6. At this time, when it is necessary to clean the photovoltaic panel 4, the staff starts Motor 2 5, causing Motor 2 5 to drive the reciprocating lead screw 6 to start rotating. The rotation of the reciprocating lead screw 6 drives the moving block 7 to start moving. The movement of the moving block 7 drives the scraping rod 8 to start moving. The movement of the scraping rod 8 clears the impurities falling on the photovoltaic panel 4, keeping the photovoltaic panel 4 with a high light transmittance, allowing more sunlight to pass through and be converted into electrical energy, thereby improving the power generation efficiency. At the same time, it avoids the hot spot effect caused by pollutant shielding, extends the service life of the photovoltaic panel 4, and reduces the maintenance workload and cost caused by problems such as corrosion. When the photovoltaic panel 4 is adjusted to a certain angle, it contacts and pushes one end of the contact rod 12. The movement of the contact rod 12 contacts and pushes the push rod 13 to start moving. The movement of the push rod 13 contacts and pushes the limit block 15 to start moving downward along the direction of the slide rail 14. The movement of the limit block 15 disengages from the reciprocating lead screw 6 to release the restriction on the reciprocating lead screw 6, ensuring that the photovoltaic panel 4 can be cleaned only at a certain angle, making it easier to clean the impurities and easier for the impurities to slide along the adjusted angle of the photovoltaic panel 4, avoiding incomplete cleaning of the impurities when the photovoltaic panel 4 is flat.

[0024] Please refer to Figures 1 - 8 , on the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device for stabilizing the photovoltaic power generation equipment and a cleaning device for spraying water on the photovoltaic panel 4 are provided on the top of the bottom plate 91. By setting the stabilizing device, the safe operation of the photovoltaic power generation device is ensured. By setting the cleaning device, the cleaning effect is ensured to be more thorough.

[0025] The stabilizing device includes a sliding rod 161, a support rod 162 and a cross bar 163. The sliding rod 161 is slidably installed inside the bracket 1. The support rod 162 is fixedly installed at the bottom of the sliding rod 161. The cross bar 163 is fixedly installed on the back of the sliding rod 161. When the photovoltaic panel 4 is adjusted in one direction by moving the support rod 162 downward, the support of the support rod 162 downward on the bracket 1 is strengthened, preventing it from tipping over due to external forces, ensuring the safe operation of the photovoltaic power generation device, reducing the risk of structural damage caused by extreme weather, improving the durability of the photovoltaic power generation device. At the same time, the support rod 162 can share part of the weight and external forces of the photovoltaic panel 4, making the force on the connecting components and rotating components more uniform, reducing the degree of wear, thereby extending the service life of these components and reducing the maintenance cost and replacement frequency of the photovoltaic power generation device.

[0026] The stabilizing device further includes a bottom rod 164, an inclined plane rod 165, an elastic telescopic rod three 166, a semi-circular ring 167 and a lifting rod 168. The bottom rod 164 is fixedly installed at the bottom of the cross bar 163. The inclined plane rod 165 is slidably installed on the top of the bottom plate 91. The elastic telescopic rod three 166 is fixedly installed on the top of the bottom plate 91. The semi-circular ring 167 is fixedly installed on the top of the movable end of the elastic telescopic rod three 166. The lifting rod 168 is fixedly installed on the circumferential surface of the movable end of the elastic telescopic rod three 166. By moving the semi-circular ring 167 to contact the rotating shaft 3, applying frictional force to the rotating shaft 3, making the adjustment process smoother and more precise, preventing the angle of the photovoltaic panel 4 from having a small deviation due to external factors, ensuring that the photovoltaic panel 4 is always at the best power generation angle, maintaining a stable power generation efficiency. At the same time, preventing the photovoltaic panel 4 from rotating or swinging randomly due to excessive wind force, reducing the risk of equipment damage, and enhancing the reliability of the photovoltaic power generation device in harsh environments.

[0027] The surfaces of the bottom rod 164 and the inclined plane rod 165 in contact with each other are both set as inclined planes. The surfaces of the inclined plane rod 165 and the lifting rod 168 in contact with each other are both set as inclined planes. A spring is provided between the sliding rod 161 and the bracket 1. By setting the inclined plane, it is ensured that the bottom rod 164 can smoothly push the inclined plane rod 165 when moving. By setting the inclined plane, it is ensured that the inclined plane rod 165 can smoothly push the lifting rod 168 when moving. By setting the spring, it is ensured that the sliding rod 161 can achieve self-resetting.

[0028] The cleaning device includes a water tank 171, a water pump 172, a water pipe 173 and a spray head 174. The water tank 171 is fixedly installed at the bottom of the bottom plate 91. The water pump 172 is fixedly installed on the top of the bottom plate 91. The water pipe 173 is fixedly installed on the top of the water pump 172. The spray head 174 is fixedly installed on the top of the bracket 1. By the water pump 172, the water inside the water tank 171 is sprayed out from the spray head 174 through the water pipe 173. For some stains with strong viscosity or close adhesion, the impact force and soaking effect of the water can soften and remove them. Compared with simple dry wiping or scraping, the cleaning effect is more thorough and can better restore the light transmittance of the photovoltaic panel 4.

[0029] The cleaning device further includes a fourth elastic telescopic rod 175, a pressing rod 176, an electric telescopic rod 177, a rack 178, a pump switch 179, and a gear 1710. The fourth elastic telescopic rod 175 is fixedly installed on the top of the bottom plate 91. The pressing rod 176 is fixedly installed on the top of the movable end of the fourth elastic telescopic rod 175. The electric telescopic rod 177 is fixedly installed on the side of the bracket 1 close to the bottom plate 91. The rack 178 is fixedly installed on the output end of the electric telescopic rod 177. The pump switch 179 is fixedly installed on the control end of the water pump 172. The gear 1710 is fixedly installed on the top of the pump switch 179. Only when the photovoltaic panel 4 is adjusted to a certain angle can the restriction on the pump switch 179 be released, which helps the water, cleaning liquid, and stains washed down during the cleaning process to flow away more smoothly from the surface of the photovoltaic panel 4 under the action of gravity, avoiding residue. This can reduce the possibility of water stains and stain residues, make the photovoltaic panel 4 cleaner, and thus better ensure its light transmittance and power generation efficiency.

[0030] The rack 178 meshes with the gear 1710, the pressing rod 176 contacts the pump switch 179, and the pressing rod 176 contacts the sliding rod 161. Through meshing, it is ensured that the rack 178 can drive the gear 1710 to rotate when moving. Through contact, it is ensured that the pressing rod 176 can restrict the pump switch 179. Through contact, it is ensured that the sliding rod 161 can drive the pressing rod 176 when moving.

[0031] When this embodiment is working: while the photovoltaic panel 4 adjusts its angle, it contacts and pushes the sliding rod 161 to start moving downward. The movement of the sliding rod 161 drives the support rod 162 to start moving downward. When the photovoltaic panel 4 adjusts to one side, the downward movement of the support rod 162 strengthens the support of the bracket 1, preventing it from toppling due to external forces, ensuring the safe operation of the photovoltaic power generation device, reducing the risk of structural damage caused by extreme weather, and improving the durability of the photovoltaic power generation device. At the same time, the support rod 162 can share part of the weight and external forces of the photovoltaic panel 4, making the forces on the connecting components and rotating components more uniform, reducing the degree of wear, thereby extending the service life of these components, reducing the maintenance cost and replacement frequency of the photovoltaic power generation device. While the support rod 162 moves downward, it drives the cross bar 163 to start moving downward. The movement of the cross bar 163 drives the bottom rod 164 to start moving downward. The movement of the bottom rod 164 contacts and pushes the inclined plane rod 165 to start moving. The movement of the inclined plane rod 165 contacts and pushes the lifting rod 168 to start moving upward. The movement of the lifting rod 168 drives the movable end of the third elastic telescopic rod 166 to move upward. The upward movement of the movable end of the third elastic telescopic rod 166 drives the semi-circular ring 167 to start moving upward. The movement of the semi-circular ring 167 contacts the rotating shaft 3 and applies frictional force to the rotating shaft 3, making the adjustment process smoother and more precise, preventing the angle of the photovoltaic panel 4 from having a slight deviation due to external factors, ensuring that the photovoltaic panel 4 is always at the best power generation angle, maintaining a stable power generation efficiency, and at the same time preventing the photovoltaic panel 4 from rotating or swinging randomly due to excessive wind force, reducing the risk of equipment damage, and enhancing the reliability of the photovoltaic power generation device in a harsh environment.

[0032] When the support rod 162 moves downward, it contacts and pushes the pressure rod 176 to start moving downward. The pressure rod 176 moves downward to release the restriction on the pump switch 179. At this time, when the photovoltaic panel 4 needs to be sprayed with water for cleaning, the staff turns on the electric telescopic rod 177 to drive the rack 178 to start moving. The movement of the rack 178 drives the gear 1710 to start rotating. The rotation of the gear 1710 drives the pump switch 179 to start rotating. The pump switch 179 turns on, and then the staff starts the water pump 172 to spray the water in the water tank 171 from the nozzle 174 through the water pipe 173. For some stains with strong viscosity or tight adhesion, the impact force and soaking effect of the water can soften and Compared with simple dry wiping or scraping, the cleaning effect is more thorough and can better restore the light transmittance of the photovoltaic panel 4. When the photovoltaic panel 4 is adjusted in angle again, the support rod 162 moves downward and no longer contacts and pushes the pressure rod 176 to start moving downward. Then, the pressure rod 176 starts to move upward and reset under the drive of the movable end of the elastic telescopic rod 4 175. The movement and reset of the pressure rod 176 restricts the pump switch 179, so that only when the photovoltaic panel 4 is adjusted to a certain angle can the restriction on the pump switch 179 be released, which helps to make the water, cleaning liquid and the washed stains used in the cleaning process flow away from the surface of the photovoltaic panel 4 more smoothly under the action of gravity to avoid residue. In this way, the possibility of water stains and stains remaining can be reduced, and the photovoltaic panel 4 can be cleaned more thoroughly, thereby better ensuring its light transmittance and power generation efficiency.
