Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic panel technology, specifically a dust removal device for new energy photovoltaic panels. Background Technology
[0002] New energy photovoltaic panels (solar photovoltaic panels) are devices that convert solar energy into electrical energy using the photoelectric effect of semiconductor materials. They are the core component of photovoltaic power generation systems. Their working principle is based on the photovoltaic effect: when sunlight shines on the photovoltaic panel, electrons in the semiconductor material absorb the light energy and are excited, resulting in charge separation and the formation of an electric current.
[0003] New energy photovoltaic (PV) panels are typically installed over large areas outdoors to collect solar energy. Because they are installed outdoors, these panels require regular cleaning to remove dust and impurities over time, minimizing their impact on power generation efficiency. Large-area outdoor PV panels are usually cleaned using specialized PV panel cleaning robots, reducing the need for manual cleaning.
[0004] Existing cleaning robots typically use built-in roller brushes to clean the surface of photovoltaic panels. However, after prolonged outdoor use, photovoltaic panels easily accumulate stubborn stains. Relying solely on the roller brushes within the cleaning robot is insufficient for quick removal, requiring multiple passes and resulting in low cleaning efficiency. Therefore, this paper proposes a new energy photovoltaic panel cleaning device to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a new energy photovoltaic panel cleaning device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The new energy photovoltaic panel cleaning device of this utility model includes a photovoltaic panel body, a cleaning robot installed on the photovoltaic panel body, and a roller brush provided at the bottom of the cleaning robot; a water tank is fixedly installed on the cleaning robot, a water pump is fixedly installed on the cleaning robot, one end of the water pump is connected to the inside of the water tank, a spray pipe is fixedly installed at one end of the cleaning robot, the spray pipe is "L" shaped, one end of the water pump is connected to the spray pipe, and a plurality of liquid outlets are opened on the surface of the spray pipe.
[0007] Furthermore, an extension tube is slidably connected to the inside of the spray pipe via an elastic rope. The surface of the extension tube has several through holes, which are offset from the liquid outlet. A horizontal plate is fixedly installed inside the spray pipe. A first electromagnet is fixedly installed at the bottom of the horizontal plate, and a second electromagnet is fixedly installed at the top of the extension tube.
[0008] Furthermore, a filter screen is fixedly installed inside both the liquid outlet and the through hole, and two symmetrically arranged arc-shaped guide plates are fixedly installed on one side of the filter screen.
[0009] Furthermore, an electric push rod is fixedly installed on one side of the extension tube, and the output end of the electric push rod is provided with several impact blocks.
[0010] Furthermore, a connecting plate is fixedly installed at the output end of the electric push rod, and several impact blocks are fixedly connected to the connecting plate, with the impact blocks being arc-shaped.
[0011] Furthermore, a multi-stage telescopic tube is fixedly installed on one side of the electric push rod. One end of the multi-stage telescopic tube is fixedly connected to the connecting plate. The multi-stage telescopic tube covers the output end of the electric push rod. The multi-stage telescopic tube is composed of several hollow round tubes that are sealed and slidably connected. An air blowing pipe connected to the inside is fixedly installed on one side of the multi-stage telescopic tube. The end of the air blowing pipe away from the multi-stage telescopic tube faces the impact block.
[0012] The advantages of this utility model are:
[0013] 1. This utility model, when the cleaning robot moves and cleans the photovoltaic panel, activates a water pump on the robot. The pump pumps the cleaning solution in the tank, allowing the cleaning robot to slowly move while the solution is sprayed out through the pump, the outlet of the spray pipe, and the through-hole of the extension pipe. The first and second electromagnets in the spray pipe are pre-energized, causing the extension pipe to slide away from the mains. As the cleaning solution enters, it is sprayed out through the outlet of the spray pipe and the through-hole of the extension pipe. The solution is guided to the surrounding area by an arc-shaped guide plate, expanding the spray area, while a filter screen blocks impurities. The required cleaning solution is quickly sprayed onto the surface of the photovoltaic panel through the through-hole and outlet, facilitating the subsequent cleaning of the panel by the internal roller brush of the cleaning robot. This structural design effectively assists in cleaning stubborn stains remaining on the photovoltaic panel. By pre-spraying the cleaning solution comprehensively, and then using the internal roller brush of the cleaning robot, stubborn stains are quickly cleaned, improving cleaning efficiency.
[0014] 2. In this invention, after the cleaning robot completes cleaning the photovoltaic panel, it activates the electric push rod, which moves several impact blocks away from the extension tube via the connecting plate. This causes the arc-shaped impact blocks to contact the roller brush. As the extension tube slides back into the spray pipe, the impact blocks continuously contact the roller brush, knocking off impurities that adhere to the brush during cleaning, thus assisting in cleaning the roller brush and ensuring it maintains high cleaning efficiency even after multiple uses. The multi-stage telescopic tube protects the output end of the electric push rod and extends its service life. Because the multi-stage telescopic tube is composed of several hollow, sealed, slidingly connected round tubes, it draws in gas when extending with the electric push rod and compresses the internal gas during sliding contraction, expelling it through the air blowing pipe. This expelled gas cleans the impact blocks and the connecting plate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figure 1-5 As shown, a new energy photovoltaic panel cleaning device includes a photovoltaic panel body 1, a cleaning robot 2 installed on the photovoltaic panel body 1, and a roller brush at the bottom of the cleaning robot 2; a water tank 3 is fixedly installed on the cleaning robot 2, and a water pump 4 is fixedly installed on the cleaning robot 2. One end of the water pump 4 is connected to the inside of the water tank 3, and a spray pipe 5 is fixedly installed at one end of the cleaning robot 2. The spray pipe 5 is L-shaped, and one end of the water pump 4 is connected to the spray pipe 5. Several liquid outlets 6 are opened on the surface of the spray pipe 5.
[0024] Specifically, an extension tube 7 is slidably connected to the inside of the spray pipe 5 via an elastic rope 8. Several through holes 9 are formed on the surface of the extension tube 7, and the through holes 9 and the outlet 6 are staggered. A horizontal plate 10 is fixedly installed inside the spray pipe 5. A first electromagnet 11 is fixedly installed at the bottom of the horizontal plate 10, and a second electromagnet 12 is fixedly installed at the top of the extension tube 7. Filter screens 13 are fixedly installed inside both the outlet 6 and the through holes 9. Two symmetrically arranged arc-shaped guide plates 14 are fixedly installed on one side of the filter screen 13.
[0025] When the cleaning robot 2 moves and cleans the photovoltaic panel body 1, the water pump 4 on the cleaning robot 2 is activated. The water pump 4 uses the cleaning liquid in the water tank 3 (the corresponding cleaning liquid is injected in advance according to actual needs) to spray out the cleaning liquid in the water tank 3 through the water pump 4, the liquid outlet 6 of the spray pipe 5 and the through hole 9 of the extension pipe 7 when the cleaning robot 2 moves slowly.
[0026] Before starting the cleaning robot 2, the first electromagnet 11 and the second electromagnet 12 inside the spray pipe 5 are pre-energized, causing them to repel each other due to their similar poles, thus allowing the extension pipe 7 to slide away from the spray pipe 5. Because the extension pipe 7 is constrained by the elastic rope 8, it will not slide out of the spray pipe 5. As the cleaning fluid enters, it is sprayed out through the outlet 6 of the spray pipe 5 and the through hole 9 of the extension pipe 7. The cleaning fluid is guided to the surrounding area by the arc-shaped guide plate 14 during spraying, thereby expanding the spraying area. Simultaneously, the filter screen 13 blocks impurities. The required cleaning fluid is quickly sprayed onto the surface of the photovoltaic panel body 1 through the through hole 9 and the outlet 6, thus cooperating with the subsequent cleaning action of the internal roller brush of the cleaning robot 2 on the photovoltaic panel body 1. When the extension pipe 7 is not needed, the first electromagnet 11 and the second electromagnet 12 are de-energized, and the extension pipe 7 slides back to its original position under the action of the elastic rope 8, thus not affecting the subsequent maintenance and repair work of the cleaning robot 2.
[0027] The structure designed above enables the cleaning of stubborn stains remaining on the photovoltaic panel body 1. By pre-spraying cleaning liquid comprehensively, and then cooperating with the roller brush in the subsequent cleaning robot 2, the stubborn stains are quickly cleaned, improving cleaning efficiency.
[0028] An electric push rod 15 is fixedly installed on one side of the extension tube 7. Several impact blocks 16 are provided at the output end of the electric push rod 15. A connecting plate 17 is fixedly installed at the output end of the electric push rod 15. Several impact blocks 16 are fixedly connected to the connecting plate 17. The impact blocks 16 are arc-shaped.
[0029] Specifically, a multi-stage telescopic tube 18 is fixedly installed on one side of the electric push rod 15. One end of the multi-stage telescopic tube 18 is fixedly connected to the connecting plate 17. The multi-stage telescopic tube 18 covers the output end of the electric push rod 15. The multi-stage telescopic tube 18 is composed of several hollow round tubes that are sealed and slidably connected. An air blowing pipe 19 that communicates with the inside is fixedly installed on one side of the multi-stage telescopic tube 18. The end of the air blowing pipe 19 away from the multi-stage telescopic tube 18 faces the impact block 16.
[0030] During operation, after the cleaning robot 2 completes cleaning the photovoltaic panel body 1, it activates the electric push rod 15. The electric push rod 15, via the connecting plate 17, moves several impact blocks 16 away from the extension tube 7, causing the arc-shaped impact blocks 16 to contact the roller brush (i.e., the bristle brush). As the extension tube 7 slides back into the spray pipe 5, the impact blocks 16 continuously contact the roller brush, knocking off impurities picked up during cleaning, thus assisting in cleaning the roller brush and ensuring it maintains efficient cleaning even after multiple uses. The multi-stage telescopic tube 18 is installed to protect the output end of the electric push rod 15 and extend its service life. Since the multi-stage telescopic tube 18 is composed of several hollow, round tubes that are sealed and slidably connected, it draws in gas when extending with the electric push rod 15, and when sliding and retracting, it compresses the internal gas and blows it out through the air blowing pipe 19, using the blown gas to clean the impact blocks 16 and the connecting plate 17.
[0031] Working principle: When the cleaning robot 2 moves and cleans the photovoltaic panel body 1, the water pump 4 on the cleaning robot 2 is activated. The water pump 4 pumps the cleaning liquid in the water tank 3, so that as the cleaning robot 2 moves slowly, the cleaning liquid in the water tank 3 is sprayed out through the water pump 4, the outlet 6 of the spray pipe 5, and the through hole 9 of the extension pipe 7. Before activating the cleaning robot 2, the first electromagnet 11 and the second electromagnet 12 in the spray pipe 5 are pre-energized, so that the like poles of the first electromagnet 11 and the second electromagnet 12 repel each other, thereby causing the extension pipe 7 to slide away from the extension pipe 7. Because the extension pipe 7 is constrained by the elastic rope 8, it will not slide out of the spray pipe 5. As the cleaning liquid enters, the cleaning liquid is sprayed out through the outlet 6 of the spray pipe 5 and the through hole 9 of the extension pipe 7. When the cleaning liquid is sprayed out, it is guided to the surroundings by the arc-shaped guide plate 14, thereby expanding the spraying area. At the same time, the filter screen 13 plays the role of blocking impurities. The required cleaning fluid is quickly sprayed onto the surface of the photovoltaic panel body 1 through the through hole 9 and the liquid outlet 6, which then works in conjunction with the cleaning robot 2's internal roller brush to clean the photovoltaic panel body 1. When the extension tube 7 is not needed, the first electromagnet 11 and the second electromagnet 12 are de-energized, and the extension tube 7 slides back to its original position under the action of the elastic rope 8, thus not affecting the subsequent maintenance and repair work of the cleaning robot 2.
[0032] After the cleaning robot 2 finishes cleaning the photovoltaic panel body 1, it activates the electric push rod 15, which moves several impact blocks 16 away from the extension tube 7 via the connecting plate 17, causing the arc-shaped impact blocks 16 to contact the roller brush. As the extension tube 7 slides back into the spray pipe 5, the impact blocks 16 continuously contact the roller brush, knocking off impurities picked up during cleaning, thus assisting in cleaning the roller brush and ensuring it maintains high-efficiency cleaning even after multiple uses. The multi-stage telescopic tube 18 is installed to protect the output end of the electric push rod 15 and extend its service life. Since the multi-stage telescopic tube 18 is composed of several hollow, round tubes that are sealed and slidably connected, it draws in air when extending with the electric push rod 15, and when sliding and retracting, it compresses the internal air and blows it out through the air blowing pipe 19, using the blown air to clean the impact blocks 16 and the connecting plate 17.
