Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and specifically to a photovoltaic power generation dust removal device. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Currently, photovoltaic power generation generally involves placing multiple photovoltaic panels in open areas, which causes a lot of dust to accumulate on the photovoltaic panels, requiring regular cleaning of the dust on the photovoltaic panels.

[0003] With the development of technology, the current method for cleaning dust on photovoltaic panels is mostly automated cleaning with dust removal equipment. This usually involves setting up dust removal equipment at the photovoltaic panel and then wiping the surface of the photovoltaic panel with cleaning cotton. However, this causes a large amount of dust to accumulate on the surface of the cleaning cotton. Currently, after the cleaning cotton has been used to remove dust from the photovoltaic panel, it is not effectively cleaned and reused. The cleaning cotton can only be replaced, which not only increases the cost of dust removal on photovoltaic panels, but also increases the labor intensity of workers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a photovoltaic power generation dust removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic power generation dust removal device includes:

[0007] A base, the upper end of which is fixedly connected to an inclined plate by a bracket, and multiple photovoltaic panels are installed on the upper end of the inclined plate;

[0008] The dust removal mechanism includes two fixed frames fixedly connected to the side walls of an inclined plate. Slider blocks are slidably connected to the inner walls of both fixed frames. A connecting plate is fixedly connected to the upper ends of both sliders. An arc-shaped groove is formed at the lower end of the connecting plate. A hollow rod is rotatably connected to the inner wall of the arc-shaped groove. A hollow plate is fixedly connected to the side wall of the hollow rod. The inner wall of the hollow rod communicates with the inner wall of the hollow plate. A horizontal plate is fixedly connected to the lower end of the hollow plate. A cleaning cotton is fixedly connected to the lower end of the horizontal plate. A strip-shaped cavity is formed inside the horizontal plate. Multiple water outlet holes are formed at the bottom of the strip-shaped cavity. The top of the strip-shaped cavity communicates with the inner wall of the hollow plate.

[0009] Preferably, a lead screw is rotatably connected to the inner wall of one of the fixed frames, and the side wall of the lead screw is threadedly connected to the side wall of the adjacent slider. A first motor is fixedly connected to the side wall of one of the fixed frames, and the movable end of the first motor is fixedly connected to one end of the lead screw.

[0010] Preferably, the connecting plate is provided with a driving mechanism, the driving mechanism including an L-shaped plate fixedly connected to the side wall of the connecting plate, a second motor fixedly connected to the side wall of the L-shaped plate, a first gear fixedly connected to the movable end of the second motor, the side wall of the hollow rod passing through the side wall of the connecting plate and fixedly connected to the second gear, and the first gear and the second gear meshing with each other.

[0011] Preferably, the L-shaped plate is provided with a water pumping mechanism, which includes a rotary joint fixedly connected to the lower end of the L-shaped plate, one end of the hollow rod located outside the connecting plate being fixedly connected to one side of the rotary joint, a water pump being installed on the upper end of the base, and the output end of the water pump being fixedly connected to the other side of the rotary joint through a water inlet pipe.

[0012] Preferably, a scraper is fixedly connected to the lower inner wall of the arc-shaped groove away from the photovoltaic panel, and a drain outlet is opened on the inner wall of the arc-shaped groove above the scraper.

[0013] This utility model has the following beneficial effects:

[0014] 1. A dust removal mechanism and a water pump mechanism are set up. When the cleaning cotton is cleaning dust on multiple photovoltaic panels, the water pump can be started, and water is pumped into the strip cavity through the water inlet pipe, rotary joint, hollow rod and hollow plate. Then the water flows out through multiple water outlet holes, wets the cleaning cotton, and increases the cleaning effect on multiple photovoltaic panels.

[0015] 2. A drive mechanism and scraper are installed. After dust removal from the photovoltaic panel, the second motor is started, which drives the hollow rod to rotate counterclockwise through the first and second gears. When the damp cleaning cotton rotates to the scraper, the scraper can squeeze the cleaning cotton, squeezing the sewage on the cleaning cotton and discharging it through the drain port. This effectively cleans the cleaning cotton, ensuring its cleanliness after dust removal and facilitating its next use. This avoids the problem in existing technologies where the cleaning cotton can only be replaced after dust removal from the photovoltaic panel, which not only increases the cost of dust removal from the photovoltaic panel but also leads to high labor intensity for workers.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A photovoltaic power generation dust removal device includes a base 1, an inclined plate 2 fixedly connected to the upper end of the base 1 by a bracket, and multiple photovoltaic panels 3 installed on the upper end of the inclined plate 2.

[0024] The dust removal mechanism includes two fixed frames 4 fixedly connected to the side walls of the inclined plate 2. The inner walls of the two fixed frames 4 are slidably connected to sliders 5. The upper ends of the two sliders 5 are fixedly connected to a connecting plate 6. The lower end of the connecting plate 6 has an arc-shaped groove 9. The inner wall of the arc-shaped groove 9 is rotatably connected to a hollow rod 10. The side wall of the hollow rod 10 is fixedly connected to a hollow plate 11. The inner wall of the hollow rod 10 communicates with the inner wall of the hollow plate 11. The lower end of the hollow plate 11 is fixedly connected to a horizontal plate 12. The lower end of the horizontal plate 12 is fixedly connected to a cleaning cotton 13. The horizontal plate 12 has a strip cavity 14. The bottom of the strip cavity 14 has multiple water outlet holes 15. The top of the strip cavity 14 communicates with the inner wall of the hollow plate 11.

[0025] One of the fixed frames 4 has a lead screw 7 rotatably connected to its inner wall. The side wall of the lead screw 7 is threadedly connected to the side wall of the adjacent slider 5. One of the fixed frames 4 has a first motor 8 fixedly connected to its side wall. The movable end of the first motor 8 is fixedly connected to one end of the lead screw 7.

[0026] It should be noted that when the horizontal plate 12 is in its initial position (e.g., Figure 3As shown), at this time, the lower surface of the cleaning cotton 13 and the upper surfaces of the multiple photovoltaic panels 3 are on the same inclined plane. When the first motor 8 rotates in the forward or reverse direction, the lead screw 7 also rotates in the forward or reverse direction, causing the slider 5 connected to the lead screw 7 to move the connecting plate 6 back and forth on the surface of the photovoltaic panels 3. Thus, the cleaning cotton 13 completes the cleaning of dust from the multiple photovoltaic panels 3. After cleaning, the connecting plate 6 returns to its initial position (as shown). Figure 2 (As shown).

[0027] The connecting plate 6 is provided with a driving mechanism, which includes an L-shaped plate 18 fixedly connected to the side wall of the connecting plate 6, a second motor 19 fixedly connected to the side wall of the L-shaped plate 18, a first gear 20 fixedly connected to the movable end of the second motor 19, and a hollow rod 10 passing through the side wall of the connecting plate 6 and fixedly connected to a second gear 21. The first gear 20 and the second gear 21 mesh with each other.

[0028] The L-shaped plate 18 is equipped with a water pumping mechanism, which includes a rotary joint 22 fixedly connected to the lower end of the L-shaped plate 18. One end of the hollow rod 10 located outside the connecting plate 6 is fixedly connected to one side of the rotary joint 22. A water pump 23 is installed on the upper end of the base 1. The output end of the water pump 23 is fixedly connected to the other side of the rotary joint 22 through the water inlet pipe 24.

[0029] When the cleaning cotton 13 is cleaning dust on multiple photovoltaic panels 3, the water pump 23 can be started, and water can be pumped into the strip cavity 14 through the water inlet pipe 24, rotary joint 22, hollow rod 10, and hollow plate 11. Then the water flows out through multiple water outlet holes 15, wetting the cleaning cotton 13 and increasing the cleaning effect on multiple photovoltaic panels 3.

[0030] It should be noted that the rotary joint 22 is a pipe connection device that allows the connected pipes to rotate relative to each other. This is existing technology, which allows the hollow rod 10 to rotate while pumping water into it.

[0031] A scraper 16 is fixedly connected to the lower inner wall of the arc-shaped groove 9 away from the photovoltaic panel 3, and a drain outlet 17 is opened on the inner wall of the arc-shaped groove 9 above the scraper 16.

[0032] After dust removal from photovoltaic panel 3, connecting plate 6 is in its initial position. Water pump 23 continues pumping water, and simultaneously, second motor 19 is started, driving hollow rod 10 to rotate counterclockwise via first gear 20 and second gear 21 (e.g., ...). Figure 3As shown), when the damp cleaning cotton 13 rotates to the scraper 16, the scraper 16 can squeeze the cleaning cotton 13, squeezing the sewage on the cleaning cotton 13 out through the drain port 17. Then, the above operation is repeated continuously, and the dust on the cleaning cotton 13 can be discharged with the sewage, which can achieve the effect of cleaning the cleaning cotton 13, ensuring the cleanliness of the cleaning cotton 13 after dust removal, and making it easy to use next time. This avoids the situation in the prior art where the cleaning cotton 13 can only be replaced after dust removal on the photovoltaic panel 3, which not only increases the cost of dust removal on the photovoltaic panel 3, but also leads to high labor intensity for the staff.

[0033] When cleaning dust from photovoltaic panel 3, the first motor 8 is driven to rotate in the forward or reverse direction. At this time, the lead screw 7 rotates in the forward or reverse direction, causing the slider 5 connected to the lead screw 7 to drive the connecting plate 6 to move back and forth on the surface of photovoltaic panel 3, thereby cleaning cotton 13 cleans the dust on multiple photovoltaic panels 3.

[0034] When the cleaning cotton 13 cleans the dust on multiple photovoltaic panels 3, the water pump 23 is started, and water is pumped into the strip cavity 14 through the water inlet pipe 24, rotary joint 22, hollow rod 10, and hollow plate 11. Then the water flows out through multiple water outlet holes 15, wetting the cleaning cotton 13 and increasing the cleaning effect on multiple photovoltaic panels 3.

[0035] After dust removal from photovoltaic panel 3, connecting plate 6 is now in its initial position (e.g., ...). Figure 2 As shown), at this time, water pump 23 continues to pump water, and at the same time, the second motor 19 is started, which drives the hollow rod 10 to rotate counterclockwise through the first gear 20 and the second gear 21 (as shown). Figure 3 As shown), when the damp cleaning cotton 13 rotates to the scraper 16, the scraper 16 can squeeze the cleaning cotton 13, squeezing the wastewater on the cleaning cotton 13 out through the drain port 17. This process is repeated continuously to remove dust from the cleaning cotton 13 along with the wastewater, effectively cleaning the cleaning cotton 13 and ensuring its cleanliness for future use. Finally, the horizontal plate 12 is rotated back to its initial position (as shown). Figure 3 (As shown).

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
