Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic array cleaning equipment, and specifically to a special cleaning equipment for photovoltaic arrays. Background Art

[0002] A photovoltaic array refers to a device in which multiple photovoltaic panels (photovoltaic modules) are combined in a certain arrangement to better collect light energy for power generation, thereby improving the light energy utilization rate. The photovoltaic array is exposed to the outdoor environment for a long time and is prone to accumulating dust, dirt, bird droppings and other obstructions. These obstructions will reduce the ability of the surface of the photovoltaic module to reflect and absorb sunlight, and thus affect the power generation efficiency of the photovoltaic array. Regularly cleaning the photovoltaic panels can remove these obstructions, ensure that the photovoltaic array can fully receive solar radiation, and improve the power generation efficiency.

[0003] At present, most cleaning equipment mainly sprays water on the photovoltaic array, and then uses a cleaning roller to rotate to clean the surface obstructions of the photovoltaic array. During the cleaning process, the sprayed water often quickly flows away along the inclined photovoltaic panel. The cleaning roller rotates on the wet surface of the photovoltaic panel, making the photovoltaic panel dirtier and dirtier. Only by using a large amount of water to wash the cleaning roller and the photovoltaic panel again can it be cleaned, resulting in poor cleaning efficiency and waste of water resources. Especially when some cleaning equipment sprays water from the top of the photovoltaic panel downwards, the dirt and dirty water of the top photovoltaic panel will flow to the bottom photovoltaic panel, resulting in the phenomenon of stain and obstruction accumulation, increasing the cleaning workload of the photovoltaic panel below the photovoltaic array.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The cleaning equipment is moved to one end of the photovoltaic panel of the photovoltaic array to be cleaned by a mobile vehicle. Cylinder one adjusts the height of the telescopic arm to achieve the effect of adjusting the height of the cleaning equipment. Cylinder two adjusts the length of the telescopic arm to achieve the effect of adjusting the lateral position of the cleaning equipment. The traction part pulls the cleaning equipment to adapt to the installation inclination angle of the photovoltaic panel and arrange it on the surface of the photovoltaic panel. Cylinder three presses the abutment ball into the inside of the support tube to achieve the installation of the cleaning equipment on the surface of the photovoltaic panel with different inclination angles.

[0027] By installing the cleaning equipment on the surface of the photovoltaic panel, the bottom surface of the water retaining plate is in contact with the middle pressure block of the adjacent photovoltaic panel, and the bottom surfaces of the positioning block and the moving block are both in contact with the surface of the photovoltaic panel through the rubber sealing pad (refer to the instruction manual). Figure 6 ), the water tank pumps water to the water pipe through the water pump, so that the water retaining plate and the positioning blocks and the moving blocks on the water intercepting mechanism block the water on the surface of the photovoltaic panel to prevent the water from being directly sprayed on the photovoltaic panel and flowing away, which is beneficial to saving water. The bottom of the brush roller (including brush roller one and brush roller two) is immersed below the water level line, and the motor three drives the brush roller to rotate so that the surface of the photovoltaic panel is immersed in water for brushing, which is beneficial to improve the effect of water washing of the photovoltaic panel.

[0028] The water supply pipe and the water extraction pipe are connected inside the space enclosed by the water retaining plate and the water intercepting mechanism, the water supply pipe delivers clean water to the space, and the water extraction pipe uses a water pump to suck the dirty water after cleaning inside the space, so that the scrubbing roller is in the circulating clean water to clean the photovoltaic panel, and the dirty water is prevented from being repeatedly used for cleaning. The bottom surface of the water retaining plate is blocked at the installation gap position of two adjacent photovoltaic panels by an air cushion to prevent the dirty water from seeping along the gap to the back of the photovoltaic panel or the middle pressure block (the workpiece that assists in supporting and fixing the photovoltaic panel in the prior art). The dirty water is not only blocked between the two water retaining plates by the water intercepting mechanism, but also is promptly extracted by the water extraction pipe to prevent the dirty water from flowing along the photovoltaic panel and contaminating the bottom photovoltaic panel. If a local area on the surface of the photovoltaic panel is found to be damaged, the water injection of the water supply pipe is stopped, and the water intercepting mechanism and the scrubbing roller are moved to the damaged area before the water above the water intercepting mechanism is drained by the water extraction pipe to prevent water from flowing from the damaged area into the photovoltaic panel.

[0029] When the motor three drives the scrubbing roller to rotate and scrub the photovoltaic panel, it also drives the transmission tube three and the transmission shaft to rotate. The transmission shaft drives the reducer through the synchronous belt two. The reducer reduces the rotation speed to make the shaft rotate slowly. The moving wheel on the shaft rolls on the top surface of the water baffle, so that the water intercepting mechanism and the scrubbing mechanism move slowly on the surface of the photovoltaic panel, so that the cleaning equipment can move along the photovoltaic panel while cleaning the photovoltaic panel, making it convenient for the scrubbing roller to move to different positions to scrub the photovoltaic panel, thereby achieving the effect of all-round cleaning of the photovoltaic panel.

[0030] The motor 4 drives the two screw rods 2 to rotate so that the threaded tube drives the two transmission blocks to move in directions away from each other, thereby causing the two moving blocks to slide in the direction away from the positioning block, and the two support seats drive the brush rollers 1 and 2 to move in directions away from each other. At the same time, the motor 2 drives the screw rod 1 to rotate to drive the two water baffles to move synchronously in directions away from each other, so that the water interception mechanism and the water baffle can enclose a wider area to be cleaned, and the brush rollers can brush wider photovoltaic panels, which is convenient for the cleaning equipment to clean photovoltaic panels of different widths on the photovoltaic array, and is conducive to improving the scalability and adaptability of the cleaning equipment.

[0031] By fixing an abutment ball at the output end of the cylinder three, the abutment ball is fixedly connected to the V-shaped frame of the cleaning device body through the traction rope one. When the mobile vehicle moves to an undulating road surface, the cleaning device body under the traction rope one and the traction rope two sags under the gravity, and the cleaning device body will not swing significantly due to the bumpy movement of the mobile vehicle, thereby preventing the cleaning device body from colliding with the photovoltaic panel. When the cleaning device body needs to be moved from one photovoltaic panel to another for cleaning, the height of the telescopic arm can be lowered, so that the traction rope one and the traction rope two are in a relaxed state. As the mobile vehicle moves, the telescopic arm drags the cleaning device body on the photovoltaic panel through the traction rope one and the traction rope two to slide and move the cleaning device body to a predetermined position. After the cleaning device body moves to a predetermined position, the cylinder three carries the abutment ball and inserts it into the supporting tube to squeeze the airbag so that the cleaning device body is crimped and fixed on the photovoltaic panel, thereby realizing a flexible connection between the cleaning device body and the telescopic arm when adjusting the position of the cleaning device body, and a rigid abutment between the cleaning device body and the telescopic arm when fixing the position of the cleaning device body, so as to achieve mobile position cleaning while protecting the photovoltaic panel.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Example 1, please refer to Figures 1 to 12, in the embodiment of the present invention, a special cleaning device for a photovoltaic array includes a mobile vehicle 100. A water tank 110 is fixed on the top of the mobile vehicle 100, and a cylinder 120 is fixed on the top of the mobile vehicle 100. A telescopic arm 130 is fixed on the top of the cylinder 120. A traction member 140 for pulling and adjusting the position of the cleaning device is fixed on the top of one end of the telescopic arm 130. It further includes a pressing member 200 for pressing and fixing the cleaning device on the surface of the photovoltaic array. A U-shaped frame 300 is fixed between the traction member 140 and the pressing member 200. Cross beams 310 are fixed at both ends of the U-shaped frame 300. Two symmetrically distributed water baffle plates 400 are slidably arranged between the two cross beams 310. A brushing mechanism 500 is slidably connected to the bottom of the U-shaped frame 300. The brushing mechanism 500 includes a carrier plate 510. Support seats 520 are slidably clamped at both ends of the bottom of the carrier plate 510. A first transmission pipe 540 and a second transmission pipe 550 are respectively rotatably connected to the bottoms of the two support seats 520. A first brushing roller 541 and a second brushing roller 551 are respectively fixed on the outer sides of the first transmission pipe 540 and the second transmission pipe 550. A water intercepting mechanism 600 fixedly connected to the carrier plate 510 is arranged at the bottom of the U-shaped frame 300. The water intercepting mechanism 600 includes an L-shaped rod 610. A slide rail 611 slidably connected to the U-shaped frame 300 is fixed on the top of the L-shaped rod 610. A positioning block 620 is fixed at the bottom of the L-shaped rod 610. Moving blocks 630 are slidably clamped at both ends of the positioning block 620. Shaft rods 640 are respectively rotated at both ends of the top of the positioning block 620. The shaft rods 640 are used to drive the brushing mechanism 500 and the water intercepting mechanism 600 to move and clean on the surface of the photovoltaic panel. An adjusting mechanism 700 is fixed on the bottom surface of the L-shaped rod 610. The adjusting mechanism 700 is used to adjust the brushing area of the first brushing roller 541 and the second brushing roller 551, and the adjusting mechanism 700 is used to adjust the position of the moving blocks 630 outside the positioning block 620.

[0047] Specifically, the mobile vehicle 100 cooperates with the telescopic arm 130 to move the main body of the cleaning device to the outside of the photovoltaic panel. The adjusting mechanism 700 adjusts the overall lengths of the first scrubbing roller 541 and the second scrubbing roller 551 so that the first scrubbing roller 541 and the second scrubbing roller 551 can adapt to scrub photovoltaic panels with different widths on different photovoltaic arrays. During cleaning, the water delivery pipe 631 injects water into the space enclosed by the water baffle 400 and the water intercepting mechanism 600, enabling the surfaces of the scrubbing rollers and the local areas of the photovoltaic panels to be immersed in water. The third motor 521 drives the scrubbing rollers to rotate in the water to clean the photovoltaic panels, which is beneficial to improving the scrubbing effect. The third motor 521 also drives the shaft rod 640 to rotate, and the moving wheels 641 on the shaft rod 640 roll on the water baffle 400, enabling the cleaning device to move along the photovoltaic panel while cleaning the photovoltaic panel, facilitating the scrubbing rollers to move to different positions to scrub the photovoltaic panel, achieving the effect of comprehensively cleaning the photovoltaic panel. The dirty water generated during the cleaning process is pumped out using the water suction pipe 632, keeping the scrubbing rollers in clean water to clean the photovoltaic panels and preventing the dirty water from affecting the cleaning effect of the photovoltaic panels. The positioning block 620 and the moving block 630 on the water intercepting mechanism 600 can block the dirty water from flowing along the photovoltaic panel, preventing the sewage from leaving stains and obstructions on the bottom photovoltaic panel.

[0048] As Figure 1 and Figure 2 shown, in this embodiment, the telescopic arm 130 includes a rectangular tube, and a rectangular rod slides inside the rectangular tube. A second cylinder for driving the rectangular rod to extend or shorten is fixed at the bottom of the telescopic arm 130. The traction member 140 includes a support plate fixed to the rectangular rod. A winding wheel is rotatably mounted on the top of the support plate. A second traction rope fixedly connected to the U-shaped frame 300 is wound around the outside of the winding wheel. A first motor for driving the winding wheel to rotate and wind or release the second traction rope is fixed to the top of the support plate.

[0049] In this embodiment, the structure of the telescopic arm 130 and the mobile vehicle 100 are both prior arts. When the output end of the second cylinder extends, the rectangular rod can move out from inside the rectangular tube, facilitating the lateral movement of the position of the main body of the cleaning device. The first motor drives the winding wheel to rotate and wind or release the second traction rope, enabling the structure below the U-shaped frame 300 of the main body of the cleaning device to adjust the inclination angle at the output end position of the third cylinder, facilitating the placement at an angle suitable for the installation angle of the photovoltaic panel.

[0050] As Figure 2 and Figure 4As shown, in this embodiment, the crimping member 200 includes a cylinder three 210. A contact ball 220 is fixed to the output end of the cylinder three 210. A plurality of first traction ropes 230 are evenly fixed to the outside of the contact ball 220. A support cylinder 240 fixedly connected to the U-shaped frame 300 is fixed to the bottom of the plurality of first traction ropes 230. An airbag 250 is fixed inside the support cylinder 240. A protrusion 420 is fixed to one side of the bottom of the water baffle 400. An air cushion one 421 is embedded and fixed to the bottom surface of the protrusion 420. An air pipe 422 communicating with the airbag 250 is fixedly connected to the outside of the air cushion one 421.

[0051] In this embodiment, during the process of the cylinder three 210 inserting the contact ball 220 into the support cylinder 240, the contact ball 220 will squeeze the airbag 250 to make the gas inside the airbag 250 be transported into the air cushion one 421 through the air pipe 422, causing the volume of the air cushion one 421 to expand. First, the expansion of the air cushion one 421 enables the bottom surface of the water baffle 400 to be in close contact with the fixed frame 810 at the edge of the photovoltaic panel. At the same time, the expanded air cushion one 421 can be clamped into the gap position between adjacent fixed frames 810, and cooperate with the contact ball 220 to squeeze the water baffle 400 through the U-shaped frame 300, so that the water baffle 400 can be firmly sealed and fixed on the surface of the photovoltaic panel.

[0052] As Figure 2 shown, in this embodiment, a first lead screw 311 rotatably connected to the water baffle 400 is rotated on the top of the cross beam 310. A motor two 312 for driving the first lead screw 311 to rotate is fixed to one end of the cross beam 310.

[0053] In this embodiment, the motor two 312 drives the first lead screw 311 to rotate, so that the two water baffles 400 threadedly connected to it can move closer to or away from each other, and are adaptively installed at the edges of different photovoltaic panels. The first lead screw 311 is a bidirectional lead screw, and thus can drive the two water baffles 400 to rotate and move synchronously in opposite directions.

[0054] As Figure 7 shown, in this embodiment, the adjusting mechanism 700 includes a motor four 710 fixed to the bottom surface of the L-shaped rod 610. The output end of the motor four 710 is fixedly connected to a second lead screw 720. A threaded tube 721 is threadedly sleeved on the outside of the second lead screw 720. One end of the threaded tube 721 is fixed with a connecting rod 730. The bottom end of the connecting rod 730 is fixed with a transmission block 731. The two ends of the transmission block 731 are respectively fixedly connected to the moving block 630 and the support seat 520.

[0055] In this embodiment, when it is necessary to increase the brushing length of the brush roller 1 541 and the brush roller 2 551, or when it is necessary to extend the water blocking range of the water cut-off mechanism 600, the motor 4 710 drives the screw rod 2 720 to rotate so that the threaded tube 721 is screwed and moved away from the screw rod 2 720, and the threaded tube 721 drives the connecting rod 730 and the transmission block 731 to move, thereby enabling the brush roller 1 541 and the brush roller 2 551 to move in directions away from each other, thereby increasing the brushing length of the brush roller 1 541 and the brush roller 2 551, and the moving block 630 moves in a direction away from the positioning block 620, thereby extending the water blocking range of the positioning block 620 and the moving block 630.

[0056] like Figure 5 and Fig. 9 As shown, in this embodiment, a transmission tube three 530 is rotatably provided on the top of the support seat 520, a motor three 521 for driving the transmission tube three 530 to rotate is fixed to the outer side of one support seat 520, a transmission shaft is slidably connected between the two transmission tubes three 530, a synchronous pulley one is fixed to the outer side of one transmission tube three 530 and a transmission tube one 540, and the two synchronous pulleys one are connected through a synchronous belt one transmission.

[0057] In this embodiment, motor three 521 drives transmission tube three 530 to rotate, and transmission tube three 530 drives transmission tube one 540 inside support seat 520 to rotate through synchronous belt one, and transmission tube one 540 drives brush roller one 541 to rotate. Since brush roller one 541 and fixed block 560 on brush roller two 551 are staggered and evenly plugged in, the rotation of brush roller one 541 will drive brush roller two 551 to rotate synchronously, so that motor three 521 drives brush roller one 541 and brush roller two 551 to rotate and brush photovoltaic panels. A slide groove one is provided on the outer side of the transmission shaft, and a slider one is fixed on the inner side of the transmission tube three 530, which is slidably engaged with the slide groove one, so that the transmission tube three 530 can slide on the transmission shaft and also rotate with the transmission shaft.

[0058] like Figure 5 As shown, in this embodiment, reducers 621 are fixed at both ends of the top of the positioning block 620, a synchronous pulley 2 is fixed to the input end of the reducer 621 and the outer side of the transmission shaft, a synchronous belt 2 is connected between the two synchronous pulleys, and the output end of the reducer 621 is fixedly connected to the corresponding position shaft 640.

[0059] When the transmission tube 3 530 rotates with the transmission shaft, the transmission shaft will rotate with the input end of the reducer 621 through the synchronous belt 2. The reducer 621 reduces the rotation speed transmitted by the transmission shaft, and then makes the shaft 640 rotate at a low speed. The rotation of the shaft 640 can make the brushing mechanism 500, the adjustment mechanism 700 and the water cut-off mechanism 600 move on the photovoltaic panel.

[0060] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, the outer side of the shaft rod 640 is slidably engaged with a moving wheel 641, and two limiting plates 410 arranged on the outer side of the moving wheel 641 are fixed to the top of the water baffle 400. The outer side of the limiting plate 410 is provided with a long slot hole for the shaft rod 640 to pass through and slide, and the top of the L-shaped rod 610 is fixed with a clamping plate that is slidably engaged with the L-shaped frame 300.

[0061] In this embodiment, during the rotation of the shaft 640, the moving wheel 641 on the shaft 640 rolls on the water baffle 400, so that the scrubbing mechanism 500, the adjusting mechanism 700 and the water cut-off mechanism 600 move on the photovoltaic panel. The moving wheel 641 can also be a gear, and then a rack is fixed on the top surface of the water baffle 400, so that the shaft 640 can be rotated to drive the scrubbing mechanism 500, the adjusting mechanism 700 and the water cut-off mechanism 600 of the cleaning device body to move. After the cleaning device body moves to the bottom of the photovoltaic array, the motor 3 521 can be driven to drive the cleaning device body to move. The output end rotates in the opposite direction, so that the moving wheel 641 of the shaft 640 rolls in the opposite direction on the top surface of the water baffle 400, so that the main body of the cleaning device can still return to the initial position, and the limit plate 410 is used to limit the moving wheel 641 on the top surface of the water baffle 400, wherein a slider 2 is fixed in the middle of the moving wheel 641, and a slide groove 2 is provided on the outer side of the shaft 640.
