Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning device technology, and in particular to a new energy photovoltaic panel cleaning device. Background Technology

[0002] During long-term use, photovoltaic panels inevitably accumulate dust, bird droppings, leaves, industrial pollutants, and other contaminants on their surface. These contaminants block sunlight from reaching the photovoltaic panels, reducing their power generation efficiency. A new energy photovoltaic panel cleaning device is a specialized device for cleaning solar photovoltaic panels. It helps workers remove contaminants from the surface of the photovoltaic panels, ensuring that they maintain good power generation performance at all times.

[0003] However, since the cleaning device for new energy photovoltaic panels removes dirt by rotating the roller brush on the surface of the photovoltaic panel and spraying cleaning water, most of the existing new energy photovoltaic panel cleaning devices on the market currently use a motor and mechanical structure to drive the roller brush to rotate. This requires an external power supply and has high requirements for the waterproof capability of the equipment. Workers are at risk of electric shock in humid environments.

[0004] Therefore, those skilled in the art have provided a new energy photovoltaic panel cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new energy photovoltaic panel cleaning device. High-speed water flow enters the rotating chamber, impacting multiple drive blades in the drive mechanism, which in turn drives the transmission rod to rotate. The transmission rod and the roller brush are respectively engaged with the first and second connecting parts. The roller brush is driven to rotate using a meshing connection between a drive gear and a driven gear, simplifying the structure and reducing power consumption.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A new energy photovoltaic panel cleaning device includes a connecting frame, a drive mechanism, and a roller brush. A telescopic rod is hinged to the middle of the upper end of the connecting frame. The drive mechanism is housed inside the connecting frame and includes two power blocks and a transmission rod. Multiple drive blades are fixedly connected to the middle of the outer wall of the transmission rod. A rotating cavity is formed at the center of the connecting frame. A rotating groove is formed inside each power block. A drive gear is rotatably connected to the upper end of the inner wall of the rotating groove on the side away from the center of the connecting frame. A driven gear is rotatably connected to the lower end of the inner wall of the rotating groove on the side away from the center of the connecting frame. A first connecting member is fixedly connected to the side of the drive gear closest to the center of the connecting frame. A second connecting member is fixedly connected to the side of the driven gear closest to the center of the connecting frame. A connecting pipe is fixedly connected to the middle of the outer wall at the front end of the connecting frame. Conveying cavities are formed at the lower ends of both sides of the connecting frame. Fixed blocks are fixedly connected to both sides of the upper end of the connecting frame. Bolts are threadedly connected to the side of each fixed block closest to the connecting center.

[0008] The above technical solution allows high-speed water to flow through the connecting pipe into the rotating cavity inside the connecting frame, impacting multiple drive blades in the drive mechanism to rotate the transmission rod. The transmission rod and the roller brush are respectively engaged with the first connecting piece fixedly connected to the drive gear and the second connecting piece fixedly connected to the driven gear. The drive gear and the driven gear mesh with each other, thereby driving the roller brush to rotate. At the same time, bolts are used to fix the fixing block and the power block together, so that after unscrewing the bolts, the power block and the connecting frame can be separated, making it easy for workers to remove and replace the roller brush.

[0009] Furthermore, a telescopic sleeve is slidably connected to the outer wall of the telescopic rod body, and a fastening ring is fixedly connected to the rear end of the telescopic sleeve;

[0010] By using the above technical solution, the inner diameter of the fastening ring is reduced by rotating the fastening knob on the fastening ring, which compresses the telescopic rod so that it can be fixed after the telescopic rod extends a certain length from the telescopic sleeve.

[0011] Furthermore, the outer walls on both sides of the connecting frame are slidably connected to the power block, and the fixing blocks are fixedly connected to the power block by bolts;

[0012] The above technical solution allows the power block to be separated from the connecting frame by unscrewing the bolts and sliding the outer walls on both sides of the connecting frame with the power block.

[0013] Furthermore, all driven gears are meshed with driving gears, and both sides of the transmission rod pass through the connecting frame and are snapped together with the first connecting piece;

[0014] Through the above technical solution, the transmission rod is snapped into place with the first connecting piece fixed on the driving gear, and the driven gear is engaged with the driving gear, so that when the transmission rod rotates, it can drive the driven gear to rotate.

[0015] Furthermore, the second connector extends through the power block on the side near the center of the connector frame and is snapped into place with the roller brush;

[0016] Through the above technical solution, the second connecting piece fixed on the driven gear is engaged with the roller brush, so that the rotation of the driven gear can drive the roller brush to rotate. After the power block and the connecting frame are separated, the roller brush can be released from the engagement state with the second connecting piece.

[0017] Furthermore, both sides of the outer wall of the transmission rod are rotatably connected to the connecting frame, and the rear end of the connecting tube is connected through the rotating cavity;

[0018] Through the above technical solution, by connecting the rear end of the connecting pipe to the rotating cavity, high-speed water flow can enter the rotating cavity through the connecting pipe and impact the drive blades. Both sides of the outer wall of the transmission rod are rotatably connected to the connecting frame, so that the drive blades rotate the transmission rod after being impacted by the water flow.

[0019] Furthermore, the conveying chambers are all connected to the rotating chambers, and the lower ends of the front and rear outer walls of the power block are fixedly connected to support wheels.

[0020] The above technical solution allows the conveying chamber to be connected to the rotating chamber, enabling the water flowing into the rotating chamber to enter the conveying chamber and finally spray out from the nozzle. The support wheel fixedly connected to the power block can support the device at a certain distance from the photovoltaic panel surface, allowing the roller brush to better remove dirt.

[0021] Furthermore, nozzles are fixedly connected to the outer walls of both the front and rear ends of the connecting frame, and the nozzles are all connected through the conveying cavity.

[0022] The above technical solution involves fixing multiple nozzles to the outer walls of both the front and rear ends of the connecting frame, which can wet the roller brush and photovoltaic panel, and simultaneously spray cleaning agent to help the roller brush remove dirt.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a new energy photovoltaic panel cleaning device, which allows high-speed water to flow through the connecting pipe into the rotating cavity inside the connecting frame, and impacts multiple drive blades in the drive mechanism to drive the transmission rod to rotate. The transmission rod and the roller brush are respectively engaged with the first connecting piece fixedly connected to the drive gear and the second connecting piece fixedly connected to the driven gear. The drive gear and the driven gear mesh with each other, thereby driving the roller brush to rotate. It does not use a motor drive, does not require an external power supply, has low requirements for the waterproof capability of the device, and avoids the risk of electric shock to workers in humid environments.

[0025] 2. The new energy photovoltaic panel cleaning device proposed in this utility model is connected by a transmission rod and a roller brush to a first connecting piece fixedly connected to the drive gear and a second connecting piece fixedly connected to the driven gear, respectively.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-5 This utility model provides a specific embodiment: a new energy photovoltaic panel cleaning device, including a connecting frame 1, a driving mechanism 5, and a roller brush 12. A telescopic rod 2 is hinged to the middle of the upper end of the connecting frame 1. The driving mechanism 5 is installed inside the connecting frame 1. The driving mechanism 5 includes two power blocks 502 and a transmission rod 504. Multiple driving blades 505 are fixedly connected to the middle of the outer wall of the transmission rod 504. A rotating cavity 501 is opened at the center of the connecting frame 1. A rotating groove 503 is opened inside the power blocks 502. The upper end of the inner wall of the rotating groove 503 on the side away from the center of the connecting frame 1 is rotatably connected. A drive gear 506 is connected to the lower end of the inner wall of the rotating groove 503 on the side away from the center of the connecting frame 1.

A bolt 10 is threadedly connected to the side of the fixing block 11 near the connecting center.

[0035] By allowing high-speed water to flow through the connecting pipe 6 into the rotating cavity 501 inside the connecting frame 1, and impacting multiple drive blades 505 in the drive mechanism 5, the transmission rod 504 is rotated. The transmission rod 504 and the roller brush 12 are respectively engaged with the first connecting piece 508 fixedly connected to the drive gear 506 and the second connecting piece 509 fixedly connected to the driven gear 507. The drive gear 506 and the driven gear 507 are meshed, thereby driving the roller brush 12 to rotate. This method does not use a motor drive, does not require an external power supply, has low requirements for the waterproof capability of the device, and avoids the risk of electric shock to workers in humid environments.

[0036] The telescopic rod 2 has a telescopic sleeve 3 slidably connected to its outer wall. A fastening ring 4 is fixedly connected to the rear end of the telescopic sleeve 3. By rotating the fastening knob on the fastening ring 4, the inner diameter of the fastening ring is reduced, compressing the telescopic rod 2. This allows the telescopic rod 2 to be fixed after extending a certain length from the telescopic sleeve 3. The outer walls on both sides of the connecting frame 1 are slidably connected to the power block 502. The fixing blocks 11 are all fixedly connected to the power block 502 by bolts 10. By unscrewing the bolts 10, the outer walls on both sides of the connecting frame 1 are slidably connected to the power block 502, allowing the power block 502 to separate from the connecting frame 1. The driven gears 507 are all meshed with the driving gears 506. The transmission rod... Both sides of the transmission rod 504 pass through the connecting frame 1 and are snapped together with the first connecting member 508. The transmission rod 504 is snapped together with the first connecting member 508 fixed on the driving gear 506. The driven gear 507 meshes with the driving gear 506, so that the rotation of the transmission rod 504 drives the driven gear 507 to rotate. The second connecting member 509, near the center of the connecting frame 1, passes through the power block 502 and is snapped together with the roller brush 12. The second connecting member 509, fixed on the driven gear 507, is snapped together with the roller brush 12, so that the rotation of the driven gear 507 drives the roller brush 12 to rotate. The power block 502 and the connecting frame... After separation, the roller brush 12 can be released from the snap-fit ​​state with the second connector 509. Both sides of the outer wall of the transmission rod 504 are rotatably connected to the connecting frame 1. The rear end of the connecting pipe 6 is connected to the rotating cavity 501. By connecting the rear end of the connecting pipe 6 to the rotating cavity 501, high-speed water flow can enter the rotating cavity 501 through the connecting pipe 6 and impact the drive blade 505. Both sides of the outer wall of the transmission rod 504 are rotatably connected to the connecting frame 1, so that the drive blade 505 rotates the transmission rod 504 after being impacted by the water flow. The conveying chambers 7 are all connected to the rotating cavity 501. The lower ends of the front and rear outer walls of the power block 502 are fixed. The device is connected to a support wheel 9. By connecting the conveying chamber 7 to the rotating chamber 501, the water flowing into the rotating chamber 501 can flow into the conveying chamber 7 and finally be sprayed out from the nozzle 8. The support wheel 9, which is fixedly connected to the power block 502, can support the device at a certain distance from the surface of the photovoltaic panel, so that the roller brush 12 can better remove dirt from the new energy photovoltaic panel cleaning device. The outer walls of the front and rear ends of the connecting frame 1 are fixedly connected to nozzles 8, which are all connected to the conveying chamber 7. By fixing multiple nozzles 8 to the outer walls of the front and rear ends of the connecting frame 1, the roller brush 12 and the photovoltaic panel can be wetted, and cleaning agent can be sprayed to help the roller brush 12 remove dirt.

[0037] Working Principle: When using this new energy photovoltaic panel cleaning device, the operator first connects the water supply pipe of the external water pump to the connecting pipe 6 on the connecting frame 1. Then, according to the height or width of the photovoltaic panel, the operator rotates the knob on the fastening ring 4 to loosen the fastening ring 4 and adjust the extension length of the telescopic rod 2. Then, the operator rotates the knob to reduce the inner diameter of the fastening ring 4, squeezing the telescopic rod 2 and fixing the extension length. Next, the operator uses the external water pump to send water mixed with cleaning agent at high speed through the connecting pipe 6 into the rotating chamber 501, impacting the multiple drive blades 505 fixedly connected to the transmission rod 504, causing the transmission rod 504 to rotate. This, in conjunction with the transmission rod 504 and the roller brush 12, respectively connects to the first connecting piece 508 and the second connecting piece 501. The 9-pin connection utilizes the meshing of the drive gear 506 and driven gear 507 to drive the roller brush 12 to rotate. Finally, the rotating roller brush 12, together with the cleaning water entering the rotating chamber 501, is sprayed out through the conveying chamber 7 and multiple nozzles 8 to wet the roller brush 12 and the surface of the photovoltaic panel, removing the dirt from the surface of the photovoltaic panel. After the cleaning work is completed, the staff unscrews the bolts 10 to separate the power block 502 and the connecting frame 1, removes the worn roller brush 12, and uses the transmission rod 504 to snap-connect the roller brush 12 to the first connecting piece 508 and the second connecting piece 509 respectively, replaces the new roller brush 12, and then fixes the fixing block 11 and the power block 502 together with the bolts 10 to complete the installation of the roller brush 12.
