Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and more particularly to an apparatus for photovoltaic power generation. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic power generation devices have been widely used in various scenarios, but there are still many problems that need to be solved in existing devices; Currently, most photovoltaic power generation devices have fixed photovoltaic panels, which cannot be tilted according to the angle of sunlight, seriously affecting power generation efficiency. Meanwhile, traditional photovoltaic devices, due to their fixed tilt angle, do not have folding and storage functions, and occupy a lot of space during transportation and storage, which is inconvenient to use, especially in outdoor emergency and mobile power supply scenarios. In addition, dust and debris easily accumulate on the surface of photovoltaic panels, blocking sunlight and further reducing power generation performance. Existing cleaning methods are mostly manual wiping, which is not only time-consuming and labor-intensive with low cleaning efficiency, but may also damage the surface of the photovoltaic panels. Furthermore, manual cleaning poses safety hazards for devices installed at high altitudes. Therefore, we propose a device for photovoltaic power generation. Summary of the Invention

[0003] Purpose of the Invention: The purpose of this invention is to provide a photovoltaic power generation device that can flexibly adjust the tilt of the photovoltaic panel according to the angle of sunlight. This photovoltaic power generation device has a folding and storage function, reducing its footprint during transportation and storage, and facilitating its portability and use in outdoor emergency situations, mobile power supply, and other scenarios. Another purpose of this invention is to provide an automatic cleaning mechanism that can remove dust and debris from the surface of the photovoltaic panel without manual wiping, avoiding the problems of time-consuming and laborious manual cleaning, damage to the photovoltaic panel, and safety hazards. This further ensures the power generation performance of the photovoltaic panel and improves the practicality and applicability of the device.

[0004] Technical solution: A device for photovoltaic power generation, including a power generation mechanism, wherein a cleaning mechanism is provided on the left side of the power generation mechanism; The power generation mechanism includes a mounting plate, on the upper surface of the mounting plate, there are symmetrically fixed bearings on the left side, and a rotating seat is rotatably mounted between the two bearings via a rotating shaft. A housing is fixedly mounted on the top of the rotating seat, and a photovoltaic panel is engaged and mounted on the inner side of the housing. The cleaning mechanism includes a base plate, the right side of which is fixedly connected to the left side of the mounting plate. Shaft plates are symmetrically fixed on the upper surface of the base plate. A reciprocating screw is mounted between the two shaft plates through a rotating shaft. A motor is fixedly connected to the front surface of the shaft plate located in front of the upper surface of the base plate. The rear end of the output shaft of the motor is fixedly connected to the front end of the reciprocating screw. The reciprocating lead screw has a lead screw sleeve threaded onto its outer side wall. A movable rod is rotatably mounted on the outer side wall of the lead screw sleeve via a rotating shaft. A rotating cylinder is located below the movable rod, and a cleaning cotton is sleeved on the outer side wall of the rotating cylinder.

[0005] Furthermore, mounting bolts are provided at all four corners of the mounting plate.

[0006] Furthermore, symmetrical shaft blocks are fixedly mounted on the upper surface of the mounting plate, and a screw is rotatably mounted between the two shaft blocks via a rotating shaft. A screw block is slidably connected to the outer side wall of the screw, and a rotating head one is fixedly connected to the top of the screw block. A traction support rod is rotatably connected to the outer side of the rotating head one via a rotating shaft, and a rotating head two is rotatably mounted to the top of the traction support rod via a rotating shaft. The top of the rotating head two is fixedly connected to the bottom of the housing, and a knob is fixedly connected to the right end of the screw.

[0007] Furthermore, a fixing block is symmetrically fixedly connected to the right side of the upper surface of the housing, and a sliding rod is fixedly connected between the two fixing blocks. The sliding rod is located inside the top of the moving rod and is slidably connected to the moving rod.

[0008] Furthermore, a toothed rack is integrally formed on the right side of the upper surface of the housing.

[0009] Furthermore, a guide sleeve is fixedly connected to the front surface of the lead screw sleeve, and a guide rod is slidably installed on the inner side of the guide sleeve. The front end and rear end of the guide rod are fixedly connected to the opposite sides of the two opposing shaft pieces, respectively.

[0010] Furthermore, a mounting block one is fixedly connected to the lower surface of the moving rod and located at the top of the rotating cylinder. A rotating column is rotatably mounted on the inner side of the mounting block one and located inside the rotating cylinder via a rotating shaft. A gear is fixedly connected to the top of the rotating column. The outer side wall of the gear meshes with the upper surface of the rack. A mounting block two is fixedly connected to the lower surface of the moving rod and located to the left of the rotating cylinder. An anti-detachment column is slidably connected to the inner side of the mounting block two. A pulling head is fixed to the left end of the anti-detachment column. A spring is fixedly connected between the pulling head and the mounting block two. The top of the anti-detachment column is inserted into the inner side of the rotating cylinder. A stop ring is fixedly connected to the outer side wall of the anti-detachment column and located to the right of the mounting block two. The stop ring is in contact with the opposite side of the rotating cylinder.

[0011] Beneficial effects: The device, through the cooperation of components such as mounting plate, shaft seat, rotating seat, screw, screw block, and traction rod, allows the screw to be driven to rotate by manually turning the knob, which in turn drives the screw block to slide left and right. This, in turn, pulls the housing around the rotating seat via the traction rod, thus achieving flexible adjustment of the tilt angle of the photovoltaic panel and facilitating the installation of different tilt angles. Rotating the knob in the opposite direction retracts the traction rod and drives the housing to rotate downwards until the housing is roughly parallel to the mounting plate, thus folding and storing the device. This significantly reduces the space occupied by the device, making it particularly suitable for outdoor emergency and mobile power supply scenarios that require frequent handling. It solves the pain points of traditional photovoltaic devices that lack folding function and are inconvenient to transport and store, and improves the portability of the device. The cleaning mechanism, through the cooperation of components such as a motor, reciprocating lead screw, lead screw sleeve, moving rod, rotating cylinder, and cleaning cotton, allows the motor to start, driving the reciprocating lead screw to rotate. This causes the lead screw sleeve and moving rod to move back and forth, ensuring that the cleaning cotton is in close contact with the surface of the photovoltaic panel and completing the wiping process. At the same time, the meshing of gears and racks drives the rotating cylinder and cleaning cotton to roll and wipe, further improving the cleaning effect. This effectively removes dust and debris from the surface of the photovoltaic panel, preventing it from blocking sunlight and causing a decrease in power generation performance. By using the combination of components such as the second mounting block, anti-detachment column, spring, and pull head, pulling the pull head can release the anti-detachment column from the rotating cylinder, allowing for quick removal of the rotating cylinder to replace the cleaning cotton. After replacement, releasing the pull head will reset the spring and fix the rotating cylinder. The operation is simple and convenient, requiring no complicated tools, thus reducing the difficulty and cost of device maintenance. Attached Figure Description

[0014] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Example like Figures 1-3 As shown, an apparatus for photovoltaic power generation is provided, including a power generation mechanism 1; The power generation mechanism 1 includes a mounting plate 101. A bearing seat 102 is symmetrically fixedly connected to the left side of the upper surface of the mounting plate 101. A rotating seat 103 is rotatably mounted between the two bearing seats 102 via a rotating shaft. A housing 104 is fixedly mounted on the top of the rotating seat 103. A photovoltaic panel 105 is engaged and mounted on the inner side of the housing 104. Mounting bolts 106 are provided at each of the four corners of the mounting plate 101; Shaft blocks 107 are symmetrically fixedly installed on the upper surface of mounting plate 101. A screw 108 is rotatably installed between the two shaft blocks 107 via a rotating shaft. A screw block 109 is slidably connected to the outer wall of the screw 108. A rotating head 110 is fixedly connected to the top of the screw block 109. A traction rod 111 is rotatably connected to the outer side of the rotating head 110 via a rotating shaft. A rotating head 112 is rotatably installed on the top of the traction rod 111 via a rotating shaft. The top of the rotating head 112 is fixedly connected to the bottom of the housing 104. A knob 113 is fixedly connected to the right end of the screw 108. A fixing block 114 is symmetrically fixedly connected to the right side of the upper surface of the housing 104. A slide rod 115 is fixedly connected between the two fixing blocks 114. The slide rod 115 is located inside the top of the moving rod 206 and is slidably connected to the moving rod 206. A toothed rack 116 is integrally formed on the right side of the upper surface of the housing 104; During installation, the entire device is first fixed in the designated installation position using the mounting bolts 106 at the four corners of the mounting plate 101, thus completing the fixed installation of the device. When it is necessary to adjust the tilt angle of the photovoltaic panel 105 to match the angle of sunlight, manually turn the knob 113 on the right end of the screw 108 to drive the screw 108 to rotate between the two shaft blocks 107. When the screw 108 rotates, it drives the screw block 109 on the outer wall to slide left and right. The screw block 109 drives the rotating head 110 at the top to move synchronously. The rotating head 110 drives the traction rod 111 to rotate through the rotating shaft. The rotating head 112 at the top of the traction rod 111 pulls the housing 104, so that the housing 104 rotates around the rotating shaft between the two shaft blocks 102 through the rotating seat 103 at the bottom, thereby adjusting the tilt angle of the photovoltaic panel 105 inside the housing 104 until the photovoltaic panel 105 reaches the optimal angle of sunlight. Then, stop turning the knob 113. When the device needs to be folded and stored, turn the knob 113 in the opposite direction to move the screw block 109 toward the shaft seat 102. The traction rod 111 retracts, causing the housing 104 to rotate downwards until the housing 104 is roughly parallel to the mounting plate 101, thus folding the device, reducing the space occupied, and facilitating transportation and storage.

[0016] like Figures 4-7 As shown, a cleaning mechanism 2 is provided to the left of the power generation mechanism 1; The cleaning mechanism 2 includes a base plate 201. The right side of the base plate 201 is fixedly connected to the left side of the mounting plate 101. Shaft plates 202 are symmetrically fixed on the upper surface of the base plate 201. A reciprocating screw 203 is mounted between the two shaft plates 202 through a rotating shaft. A motor 204 is fixedly connected to the front surface of the shaft plate 202 located in front of the upper surface of the base plate 201. The rear end of the output shaft of the motor 204 is fixedly connected to the front end of the reciprocating screw 203. A screw sleeve 205 is threadedly installed on the outer wall of the reciprocating screw 203. A movable rod 206 is rotatably installed on the outer wall of the screw sleeve 205 via a rotating shaft. A rotating cylinder 207 is provided below the movable rod 206. A cleaning cotton 208 is sleeved on the outer wall of the rotating cylinder 207. A guide sleeve 217 is fixedly connected to the front surface of the lead screw sleeve 205. A guide rod 218 is slidably installed on the inner side of the guide sleeve 217. The front end and rear end of the guide rod 218 are fixedly connected to the opposite sides of two front and rear opposite shaft pieces 202, respectively. When it is necessary to clean the surface of the photovoltaic panel 105, the motor 204 in the cleaning mechanism 2 is started first. The output shaft of the motor 204 drives the reciprocating lead screw 203 to rotate between the two shaft plates 202. When the reciprocating lead screw 203 rotates, it drives the lead screw sleeve 205 on the outer wall to move back and forth. The lead screw sleeve 205 drives the guide sleeve 217 on the front surface to slide along the guide rod 218 to ensure the stability of the lead screw sleeve 205 during movement. At the same time, the lead screw sleeve 205 drives the moving rod 206 to move back and forth synchronously through the rotating shaft. The rotating cylinder 207 below the moving rod 206 moves accordingly. The cleaning cotton 208 on the outer wall of the rotating cylinder 207 is in close contact with the surface of the photovoltaic panel 105, so as to wipe and clean the dust and debris on the surface of the photovoltaic panel 105. The movable rod 206 is guided and slid by the fixed block 114 and the slide rod 115. The movable rod 206 can rotate outside the screw sleeve 205, and then can move and rotate with the outside of the housing 104 to wipe and clean in accordance with the angle change, without affecting folding and storage. Mounting block 209 is fixedly connected to the lower surface of the moving rod 206 and the top of the rotating cylinder 207. A rotating column 210 is rotatably mounted on the inner side of mounting block 209 and the inner side of the rotating cylinder 207 via a rotating shaft. A gear 211 is fixedly connected to the top of the rotating column 210. The outer wall of the gear 211 meshes with the upper surface of the rack 116. Mounting block 22 is fixedly connected to the lower surface of the moving rod 206 and to the left of the rotating cylinder 207. 12. An anti-detachment column 213 is slidably connected to the inner side of the mounting block 212. A pulling head 214 is fixed to the left end of the anti-detachment column 213. A spring 215 is fixedly connected between the pulling head 214 and the mounting block 212. The top end of the anti-detachment column 213 is inserted into the inner side of the rotating cylinder 207. A stop ring 216 is fixedly connected to the outer wall of the anti-detachment column 213 and located to the right of the mounting block 212. The stop ring 216 is in contact with the opposite side of the rotating cylinder 207. During the cleaning process, when the moving rod 206 moves back and forth, it drives the mounting block 209 to move synchronously. The gear 211 at the top of the rotating column 210 inside the mounting block 209 meshes with the rack 116 on the upper surface of the housing 104. The rack 116 exerts a force on the gear 211, causing the gear 211 to rotate. The gear 211 drives the rotating column 210 to rotate inside the mounting block 209 and the rotating cylinder 207. The rotating column 210 drives the rotating cylinder 207 to rotate synchronously, causing the cleaning cotton 208 on the outside of the rotating cylinder 207 to roll and wipe the surface of the photovoltaic panel 105, thus improving the cleaning effect. When the cleaning cotton 208 needs to be replaced after a period of use, pull the pull head 214. The pull head 214 will drive the anti-detachment column 213 to slide to the left along the inner side of the mounting block 212. The anti-detachment column 213 will compress the spring 215. At the same time, the top of the anti-detachment column 213 will disengage from the inner side of the rotating cylinder 207, releasing the fixation on the rotating cylinder 207. At this time, the rotating cylinder 207 can be removed from the outside of the rotating column 210. After replacing the new cleaning cotton 208, put the rotating cylinder 207 back on the outside of the rotating column 210, release the pull head 214, the spring 215 will return to its original position, and push the anti-detachment column 213 to slide to the right, so that the top of the anti-detachment column 213 is re-inserted into the inner side of the rotating cylinder 207. The abutment ring 216 will fit against the rotating cylinder 207, completing the replacement of the cleaning cotton 208.

[0017] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
