Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic equipment, in particular to a photovoltaic component based on electrostatic adsorption and dust cleaning. Background Art

[0002] Photovoltaic panels can directly convert solar energy into electrical energy, and will not cause environmental pollution during the power generation process. They are a green and environmentally friendly energy production device. The wind speed is higher in plateau areas, and there is more sand and dust in windy areas. The dust will fall onto the photovoltaic panels under the action of the wind, thus affecting the normal photoelectric conversion rate of the photovoltaic panels.

[0003] Due to the strong wind in the plateau area, the normal electrostatic adsorption device will not have enough electrostatic adsorption force, which will cause the dust originally adsorbed on the electrostatic cleaning device to be blown off by the wind. This will not only reduce the adsorption and cleaning effect, but also cause more and more dust to accumulate on the photovoltaic panels, thereby affecting the photoelectric conversion rate of the photovoltaic panels. Summary of the invention

[0004] The purpose of the present invention is to provide a photovoltaic component based on electrostatic adsorption cleaning to solve the problem that due to the strong wind in plateau areas, the normal electrostatic adsorption device has insufficient electrostatic adsorption force, which will cause the dust originally adsorbed on the electrostatic cleaning device to be blown off by the wind, which will not only reduce the adsorption and cleaning effect, but also cause more and more dust to accumulate on the photovoltaic panel, thereby affecting the photoelectric conversion rate of the photovoltaic panel.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a photovoltaic assembly based on electrostatic adsorption cleaning, comprising an installation box, a photovoltaic panel is fixedly installed in the installation box, a fixing frame is fixedly installed on the left outer wall and the right outer wall of the photovoltaic panel, and an L-shaped mounting plate is fixedly installed on the top of the two fixing frames, and further comprising:

[0007] Two power generation mechanisms, the power generation mechanism includes an L-shaped movable plate slidably mounted on an L-shaped mounting plate, the L-shaped movable plate penetrates the L-shaped mounting plate, an L-shaped toothed plate is fixedly mounted on the back of the L-shaped movable plate, a rotating rod is rotatably mounted on the fixed frame, a friction roller is fixedly mounted on the rotating rod, a transmission gear is fixedly mounted on the rotating rod, and the transmission gear is meshed with the L-shaped toothed plate.

[0008] Furthermore, a telescopic spring is fixedly installed on the left side of the L-shaped mounting plate, and a movable plate is fixedly installed on the left end of the telescopic spring;

[0009] A limiting sliding rod is fixedly installed on one end of the two L-shaped mounting plates close to each other. The limiting sliding rod passes through the two movable plates and is slidably connected with the two movable plates.

[0010] Furthermore, an adsorption mechanism is provided on the two fixing frames. The adsorption mechanism includes a reciprocating screw rotatably installed on the two fixing frames. The reciprocating screw penetrates through the corresponding fixing frame, and a plurality of transmission fan blades are fixedly sleeved on the reciprocating screw.

[0011] Furthermore, a U-shaped plate is threadedly sleeved on the reciprocating screw. A rotating round rod is rotatably installed in the U-shaped plate. The limiting slide rod penetrates through the U-shaped plate and is slidably connected with the U-shaped plate. A second friction roller is fixedly sleeved on the rotating round rod.

[0012] Furthermore, the front end of the rotating round rod extends outside the U-shaped plate. A rotating gear is fixedly sleeved on the outer wall of the rotating round rod. A rotating toothed plate is fixedly installed on the two fixing frames. The rotating gear meshes with the rotating toothed plate.

[0013] Furthermore, transmission mechanisms are respectively provided on the two L-shaped movable plates. The transmission mechanism includes a connecting rod hinged to the end of the L-shaped movable plate. The top end of the connecting rod is hinged with a rectangular baffle. The rectangular baffle penetrates through the fixing frame and is slidably connected with the fixing frame.

[0014] Furthermore, a connecting plate is fixedly installed on the right side of the rotating rod. A rectangular frame is arranged above the connecting plate. A plurality of dust removal plates are fixedly installed in the rectangular frame.

[0015] Furthermore, a telescopic rod is fixedly installed on the top of the connecting plate. The top end of the telescopic rod is fixedly connected with a plurality of dust removal plates. A dust removal spring is wound around the telescopic rod. The bottom end of the dust removal spring is fixedly connected with the connecting plate. The top end of the dust removal spring is fixedly connected with a plurality of dust removal plates.

[0016] The present invention has the following beneficial effects:

[0017] (1) For a photovoltaic module based on electrostatic adsorption and dust cleaning of the present invention, the movement of the L-shaped movable plate will drive the synchronous movement of the L-shaped toothed plate. The L-shaped toothed plate will drive the rotation of the rotating rod under the action of the transmission gear. The rotating rod will drive the rotation of the first friction roller. At this time, the rotation directions of the first friction roller and the second friction roller are exactly opposite. The second friction roller that has cleaned the dust will come into contact with the first friction roller during the continuous movement. At this time, the first friction roller and the second friction roller will generate contact friction in opposite directions. Since the length of the first friction roller is greater than that of the second friction roller, all surfaces of the second friction roller will be subjected to friction, which not only increases the friction force but also enlarges the friction area. The static electricity generated by the friction will be stored by the second friction roller, effectively avoiding the influence on the dust cleaning effect due to insufficient static electricity when the second friction roller adsorbs dust on the surface of the photovoltaic panel.

[0018] (2) For a photovoltaic module based on electrostatic adsorption and dust cleaning of the present invention, under the continuous movement of the C-shaped plate, it will contact and push the movable plate to move. At this time, the movable plate will cause the telescopic spring to undergo compressive deformation. The movable plate will drive the L-shaped movable plate to move synchronously. The L-shaped movable plate will drive the connecting rod to move away from the photovoltaic panel. The connecting rod will drive the rectangular baffle to rise along the fixed frame. When the C-shaped plate drives the second friction roller away from above the photovoltaic panel, at this time, the rectangular baffle will also move to a position higher than the photovoltaic panel during the rising process, avoiding the situation that during the cleaning of the dust on the second friction roller, due to the relatively high wind speed, the cleaned dust is blown back to the surface of the photovoltaic panel again, thereby reducing the adsorption pressure of the second friction roller and improving the cleaning effect of the dust on the surface of the photovoltaic panel;

[0019] (3) For a photovoltaic module based on electrostatic adsorption and dust cleaning of the present invention, due to the relatively high wind speed in the plateau area, the wind will blow several driving fan blades to rotate. The driving fan blades will drive the reciprocating screw to rotate. The reciprocating screw will drive the C-shaped plate to move towards the fixed frame. The C-shaped plate drives the rotating round rod to move. The rotating round rod drives the second friction roller to move. The rotating gear on the second friction roller will cause the rotating round rod to rotate by itself under the action of the rotating tooth plate. The second friction roller will rotate by itself during the movement. When the second friction roller passes above the photovoltaic panel, it will suck the dust on the surface of the photovoltaic panel onto the second friction roller. Since the second friction roller is constantly rotating by itself, it can adsorb the dust under the action of static electricity of the second friction roller, making the surface of the second friction roller fully adsorb dust, further improving the adsorption effect and preventing dust from accumulating on the surface of the second friction roller and reducing its electrostatic adsorption effect;

[0020] (4) For a photovoltaic module based on electrostatic adsorption and dust cleaning of the present invention, as the rotating round rod continuously moves on the reciprocating screw, the second friction roller will contact several dust removal plates. During the movement of the second friction roller, due to the continuous rotation of the second friction roller, several dust removal plates will scrape the dust adsorbed on the second friction roller. The dust will fall to the ground from the gaps between several dust removal plates. Since the shape of the second friction roller is circular, during the movement of the second friction roller, the dust removal plates will always be in contact with the surface of the second friction roller under the elastic force of the telescopic rod, thereby improving the cleaning effect of the dust on the second friction roller.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 - Figure 8As shown, the present invention is a photovoltaic assembly based on electrostatic adsorption cleaning, including an installation box 1, a photovoltaic panel 2 is fixedly installed in the installation box 1, a fixing frame 3 is fixedly installed on the left outer wall and the right outer wall of the photovoltaic panel 2, and an L-shaped mounting plate 4 is fixedly installed on the top of the two fixing frames 3, and also includes:

[0035] Two power generation mechanisms 5, the power generation mechanism 5 includes an L-shaped movable plate 504 slidably mounted on the L-shaped mounting plate 4, the L-shaped movable plate 504 penetrates the L-shaped mounting plate 4, an L-shaped toothed plate 505 is fixedly mounted on the back of the L-shaped movable plate 504, a rotating rod 506 is rotatably mounted on the fixed frame 3, a friction roller 507 is fixedly sleeved on the rotating rod 506, a transmission gear 508 is fixedly sleeved on the rotating rod 506, and the transmission gear 508 is meshed with the L-shaped toothed plate 505.

[0036] like Figure 3 As shown, a telescopic spring 501 is fixedly installed on the left side of the L-shaped mounting plate 4, and a movable plate 502 is fixedly installed on the left end of the telescopic spring 501;

[0037] A limiting slide bar 503 is fixedly installed at one end of the two L-shaped mounting plates 4 close to each other. The limiting slide bar 503 passes through the two movable plates 502 and is slidably connected to the two movable plates 502 .

[0038] Under the action of the continuous movement of the L-shaped plate 603, it will contact and push the movable plate 502 to move. At this time, the movable plate 502 will cause the telescopic spring 501 to be compressed and deformed, and the movable plate 502 will drive the L-shaped movable plate 504 to move synchronously.

[0039] like Figure 7 As shown, an adsorption mechanism 6 is provided on the two fixing frames 3 , and the adsorption mechanism 6 includes a reciprocating screw 601 rotatably mounted on the two fixing frames 3 , the reciprocating screw 601 passes through the corresponding fixing frames 3 , and a plurality of transmission blades 602 are fixedly sleeved on the reciprocating screw 601 .

[0040] Since the wind speed in the plateau area is relatively high, the wind will drive a number of transmission blades 602 to rotate, and the transmission blades 602 will drive the reciprocating screw 601 to rotate.

[0041] like Figure 1 As shown, a threaded sleeve of a shaped plate 603 is provided on the reciprocating screw 601, a rotating round rod 604 is rotatably installed inside the shaped plate 603, a limiting slide rod 503 passes through the shaped plate 603 and is slidably connected to the shaped plate 603, and a friction roller 605 is fixedly sleeved on the rotating round rod 604.

[0042] The reciprocating screw 601 will drive the profile plate 603 to move toward the direction close to the fixed frame 3, the profile plate 603 drives the rotating round rod 604 to move, and the rotating round rod 604 drives the friction roller 2 605 to move.

[0043] like Figure 1 As shown, the front end of the rotating rod 604 extends to the outside of the shaped plate 603, and a rotating gear 606 is fixedly sleeved on the outer wall of the rotating rod 604. A rotating toothed plate 607 is fixedly installed on the two fixing frames 3, and the rotating gear 606 is meshed with the rotating toothed plate 607.

[0044] The rotating gear 606 on the friction roller 605 will cause the rotating round rod 604 to rotate on its own under the action of the rotating tooth plate 607, and the friction roller 605 will rotate on its own during the movement. When the friction roller 605 passes over the photovoltaic panel 2, the dust on the surface of the photovoltaic panel 2 will be sucked onto the friction roller 605. Since the friction roller 605 is constantly rotating on its own, the dust can be adsorbed under the action of the static electricity of the friction roller 605, so that the surface of the friction roller 605 can fully adsorb the dust, further improving the adsorption effect, and preventing dust from accumulating on the surface of the friction roller 605 and reducing its static adsorption effect.

[0045] like Figure 2 As shown, a transmission mechanism 7 is respectively provided on the two L-shaped movable plates 504, and the transmission mechanism 7 includes a connecting rod 701 hingedly installed at the end of the L-shaped movable plate 504, and a rectangular baffle 702 is hingedly installed on the top of the connecting rod 701. The rectangular baffle 702 passes through the fixed frame 3 and is slidably connected to the fixed frame 3.

[0046] The movable plate 502 will drive the L-shaped movable plate 504 to move synchronously, and the L-shaped movable plate 504 will drive the connecting rod 701 to move away from the photovoltaic panel 2. The connecting rod 701 will drive the rectangular baffle 702 to rise along the fixed frame 3. When the L-shaped plate 603 drives the friction roller 2 605 to leave the top of the photovoltaic panel 2, the rectangular baffle 702 will also move to a position higher than the photovoltaic panel 2 during the rising process, avoiding the dust on the friction roller 2 605 from being blown back to the surface of the photovoltaic panel 2 due to the high wind speed during the dust cleaning process, thereby reducing the adsorption pressure of the friction roller 2 605 and improving the dust cleaning effect on the surface of the photovoltaic panel 2.

[0047] like Figure 8 As shown, a connecting plate 703 is fixedly installed on the right side of the rotating rod 506 , a rectangular frame 705 is provided above the connecting plate 703 , and a plurality of dust removal plates 706 are fixedly installed in the rectangular frame 705 .

[0048] As the rotating round rod 604 continues to move on the reciprocating screw 601, the friction roller 605 will contact a plurality of dust removal plates 706. During the movement of the friction roller 605, due to the continuous rotation of the friction roller 605, the plurality of dust removal plates 706 will scrape off the dust adsorbed on the friction roller 605, and the dust will fall to the ground from the gaps between the plurality of dust removal plates 706.

[0049] As Figure 8 shown, a telescopic rod 704 is fixedly installed at the top of the connecting plate 703. The top end of the telescopic rod 704 is fixedly connected to a plurality of dust removal plates 706. A dust removal spring 707 is wound around the telescopic rod 704. The bottom end of the dust removal spring 707 is fixedly connected to the connecting plate 703. The top end of the dust removal spring 707 is fixedly connected to a plurality of dust removal plates 706.

[0050] Since the shape of the second friction roller 605 is circular, during the movement of the second friction roller 605, the dust removal plate 706 will always be in contact with the surface of the second friction roller 605 under the elastic force of the telescopic rod 704, thereby improving the cleaning effect of the dust on the second friction roller 605.

[0051] During use, the movement of the L-shaped movable plate 504 will drive the L-shaped toothed plate 505 to move synchronously. The L-shaped toothed plate 505 will drive the rotating rod 506 to rotate under the action of the transmission gear 508. The rotating rod 506 will drive the first friction roller 507 to rotate. At this time, the rotation directions of the first friction roller 507 and the second friction roller 605 are exactly opposite. The second friction roller 605 that has been cleaned of dust will come into contact with the first friction roller 507 during the continuous movement. At this time, the first friction roller 507 and the second friction roller 605 will generate contact friction in opposite directions. Since the length of the first friction roller 507 is greater than the length of the second friction roller 605, all surfaces of the second friction roller 605 will be subjected to friction, which not only increases the friction force but also increases the friction area. The static electricity generated by the friction will be stored by the second friction roller 605, effectively preventing the second friction roller 605 from having insufficient static electricity when adsorbing dust on the surface of the photovoltaic panel 2, thereby affecting the dust cleaning effect; under the continuous movement of the C-shaped plate 603, it will contact and push the movable plate 502 to move. At this time, the movable plate 502 will cause the telescopic spring 501 to undergo compressive deformation. The movable plate 502 will drive the L-shaped movable plate 504 to move synchronously. The L-shaped movable plate 504 will drive the connecting rod 701 to move away from the photovoltaic panel 2. The connecting rod 701 will drive the rectangular baffle 702 to rise along the fixed frame 3. When the C-shaped plate 603 drives the second friction roller 605 away from above the photovoltaic panel 2, at this time, the rectangular baffle 702 will also move to a position higher than the photovoltaic panel 2 during the rising process, preventing the dust cleaned off from being blown back onto the surface of the photovoltaic panel 2 by the strong wind during the cleaning of the dust on the second friction roller 605, thereby reducing the adsorption pressure of the second friction roller 605 and improving the dust cleaning effect on the surface of the photovoltaic panel 2;

[0052] Since the wind speed in the plateau area is relatively high, the wind will drive several transmission blades 602 to rotate, and the transmission blades 602 will drive the reciprocating screw 601 to rotate, and the reciprocating screw 601 will drive the profile plate 603 to move in the direction close to the fixed frame 3, and the profile plate 603 drives the rotating round rod 604 to move, and the rotating round rod 604 drives the friction roller 2 605 to move, and the rotating gear 606 on the friction roller 2 605 will cause the rotating round rod 604 to rotate on its own under the action of the rotating gear plate 607, and the friction roller 2 605 will rotate on its own during the movement, and the friction roller 2 605 will absorb the dust on the surface of the photovoltaic panel 2 onto the friction roller 2 605 when passing over the photovoltaic panel 2. Since the friction roller 2 605 is constantly rotating on its own, the dust can be adsorbed by the static electricity of the friction roller 2 605, so that the friction roller 2 605 The surface of the friction roller 605 can fully absorb dust, further improving the adsorption effect and preventing dust from accumulating on the surface of the friction roller 605 and reducing its electrostatic adsorption effect; as the rotating round rod 604 continues to move on the reciprocating screw 601, the friction roller 605 will contact a plurality of dust removal plates 706. During the movement of the friction roller 605, due to the continuous rotation of the friction roller 605, the plurality of dust removal plates 706 will scrape off the dust adsorbed on the friction roller 605, and the dust will fall to the ground from the gaps between the plurality of dust removal plates 706. Since the shape of the friction roller 605 is circular, during the movement of the friction roller 605, the dust removal plates 706 will always be in contact with the surface of the friction roller 605 under the elastic force of the telescopic rod 704, thereby improving the cleaning effect of the dust on the friction roller 605.
