Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel cleaning, and in particular to an automatic photovoltaic panel cleaning device. Background Art

[0002] Photovoltaic panels are devices that use the photovoltaic effect to convert sunlight into electrical energy, also known as solar panels or photovoltaic panels. The core part of photovoltaic panels is usually made of semiconductor materials such as monocrystalline silicon, polycrystalline silicon or amorphous silicon. These materials have good photoelectric conversion efficiency and stability. Cleaning photovoltaic panels is a key step to maintain their efficient operation and extend their service life. Cleaning photovoltaic panels helps ensure maximum collection and conversion efficiency of solar energy. The best time to clean is in the morning or evening, and avoid cleaning when the sun is high, because the glass surface at high temperature may be damaged by the impact of rapid cooling. Photovoltaic panel cleaning in the prior art is mainly carried out manually, which consumes a lot of labor and requires water for cleaning. Using rainwater to clean photovoltaic panels can effectively save water resources. Summary of the invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is: an automatic cleaning device for photovoltaic panels, including a base device, the base device including a bottom plate, a vertical frame fixedly installed on the bottom plate, a closing device is arranged on the base device, the closing device includes a photovoltaic seat, the photovoltaic seat is fixedly installed on the vertical frame, the closing device is used to close and clean the photovoltaic panels, the closing device is provided with a collecting device, the collecting device includes a lower fixed frame, and the collecting device is used to collect rainwater.

[0004] Furthermore, the base device includes two side connecting frames fixedly mounted on the vertical frame, water tanks are fixedly mounted on the side connecting frames, the two water tanks are connected by a connecting pipe, a water pipe is fixedly mounted on the water tank, a water pump is arranged in the water tank, and the water pump is connected to the water pipe.

[0005] Furthermore, a float mechanism is provided in the water tank, and the float mechanism includes a closing plate rotatably mounted on the water tank, a sensor fixedly mounted on the closing plate, a sliding seat fixedly mounted in the water tank, a float rod slidably mounted on the sliding seat, a float fixedly mounted on the float rod, a sliding seat rotatably mounted on the float rod, a closing slide rail fixedly mounted on the bottom of the closing plate, and the slide seat slides in the closing slide rail.

[0006] The water tank is filled with water, and the water in the water tank is pumped into the water pipe through a water pump and then enters the horizontal water pipe.

[0007] When rainwater enters the water tank, the float will float on the water surface. As the water level in the water tank gets higher and higher, the float and the float rod will rise. The float rod will rise along the sliding seat, driving the sliding seat to rise. The sliding seat slides in the closing slide rail, thereby driving the closing plate to rotate relative to the water tank. When the closing plate rotates to a certain extent, the closing plate will close the water tank, and external rainwater can no longer enter the water tank.

[0008] Furthermore, the closing device includes a photovoltaic panel fixedly mounted on a photovoltaic base, a bidirectional electric cylinder fixedly mounted on the photovoltaic base, cleaning boxes fixedly mounted on two output ends of the bidirectional electric cylinder, a light sensor and a large sliding block fixedly mounted on one of the cleaning boxes, a rain sensor and a small sliding block fixedly mounted on the other cleaning box, the small sliding block and the large sliding block are slidably mounted, and a water spraying mechanism and a wiping mechanism are provided on the cleaning box.

[0009] Furthermore, the water spraying mechanism includes a pipe bracket fixedly mounted on the cleaning box, a horizontal water pipe fixedly mounted on the pipe bracket, the horizontal water pipe and the water supply pipe fixedly mounted, a plurality of flushing water pipes fixedly mounted on the horizontal water pipe, and a spray head fixedly mounted on the flushing water pipe.

[0010] Furthermore, the wiping mechanism includes a slide cylinder fixedly mounted on the cleaning box and a movable track, a rag rack is slidably mounted on the movable track, a rag piece is fixedly mounted on the rag rack, the rag rack is connected to the slide cylinder, and the slide cylinder drives the rag rack to slide along the movable track.

[0011] Furthermore, a controller is provided on the base plate, and the controller is electrically connected to the light sensor, sensor, bidirectional electric cylinder, slide cylinder, water pump and rain sensor. The rain sensor has a higher priority than the light sensor. When the rain sensor detects rain and the closing plate is not closed, the cleaning box opens.

[0012] When the light sensor detects sunlight, the two-way electric cylinder extends and drives the two cleaning boxes to move outward, exposing the photovoltaic panels, which then generate electricity. When the light sensor does not detect sunlight, the two-way electric cylinder contracts and drives the cleaning boxes to slide inward. The cleaning boxes close the photovoltaic panels, and the photovoltaic panels can now be cleaned. The water entering the horizontal water pipe is sprayed onto the surface of the photovoltaic panels through the flushing pipe and the nozzle. The slide cylinder drives the rag rack to slide along the moving track, driving the rag to scrub the surface of the photovoltaic panels after the spraying. The operating frequencies of the water spraying mechanism and the wiping mechanism can be set through the controller.

[0013] When the rain sensor detects rain, the two-way electric cylinder extends to drive the two cleaning boxes to move outward, thereby driving the lower fixed frame to move outward. When the closing plate is closed, the sensor transmits a signal to the controller, causing the two-way electric cylinder to contract and close the cleaning box. When the light sensor detects sunlight, the cleaning box opens again.

[0014] Furthermore, the collecting device includes an ejection slide column fixedly installed in the lower fixed frame, an outer push rod is slidably installed on the ejection slide column, an ejection spring is arranged between the outer push rod and the lower fixed frame, a filter bucket is fixedly installed on the water tank, a switch plate is slidably installed on the filter bucket, a slide column is fixedly installed on the filter bucket, the switch plate and the slide column are slidably installed, a slide column spring is arranged between the switch plate and the slide column, a small push plate is fixedly installed on the switch plate, the outer push rod cooperates with the small push plate, and the elastic force of the ejection spring is greater than the elastic force of the slide column spring.

[0015] Furthermore, an upper filter plate and a lower filter plate are provided in the filter bucket, the upper filter plate is used to filter large debris such as leaves, etc., and the lower filter plate is used to finely filter rainwater.

[0016] When the rain sensor controls the cleaning box to open, the cleaning box slides outward and pushes the outer push rod to slide outward through the lower fixed frame and the push-out spring, thereby pushing the small push plate and the switch plate to slide outward. The switch plate slides along the sliding column, and the sliding column spring is compressed. After the switch plate is opened, rainwater can enter the filter bucket, filter large debris such as leaves through the upper filter plate, and filter rainwater through the lower filter plate. The filtered rainwater enters the water tank.

[0017] Compared with the prior art, the present invention has the following advantages: (1) the collecting device provided in the present invention can perform multi-layer filtration on rainwater when it rains, and collect the filtered rainwater, and use the collected rainwater to rinse and scrub the photovoltaic panels, thereby saving water resources; (2) the closing device provided in the present invention is opened when there is sunlight, so that the photovoltaic panels can make full use of solar energy, and is closed when there is no light, and the photovoltaic panels can be cleaned; (3) the float mechanism provided in the present invention closes the water tank when the water tank is full, so that the collecting device no longer collects rainwater, and the degree of automation is high; (4) the wiping mechanism provided in the present invention will only operate when the closing device closes the photovoltaic panel, thereby preventing the photovoltaic panel from being cleaned during solar power generation and preventing leakage.

DETAILED DESCRIPTION

[0029] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Example: Reference Figure 1-Figure 10 A photovoltaic panel automatic cleaning device includes a base device, the base device includes a bottom plate 101, a stand 102 is fixedly mounted on the bottom plate 101, a closing device is arranged on the base device, the closing device includes a photovoltaic seat 201, the photovoltaic seat 201 is fixedly mounted on the stand 102, the closing device is used to close and clean the photovoltaic panel, the closing device is provided with a collecting device, the collecting device includes a lower fixed frame 301, and the collecting device is used to collect rainwater.

[0031] like Figure 3 , Figure 4 As shown, the base device includes two side connecting frames 103 fixedly mounted on the vertical frame 102, a water tank 106 is fixedly mounted on the side connecting frames 103, the two water tanks 106 are connected via a connecting pipe 104, a water pipe 105 is fixedly mounted on the water tank 106, a water pump 107 is arranged in the water tank 106, and the water pump 107 is connected to the water pipe 105.

[0032] like Figure 3 , Figure 4 As shown, a float mechanism is provided in the water tank 106, and the float mechanism includes a closing plate 111 rotatably mounted on the water tank 106, a sensor 114 is fixedly mounted on the closing plate 111, a sliding seat 110 is fixedly mounted in the water tank 106, a float rod 109 is slidably mounted on the sliding seat 110, a float 108 is fixedly mounted on the float rod 109, a slide seat 112 is rotatably mounted on the float rod 109, a closing slide rail 113 is fixedly mounted on the bottom of the closing plate 111, and the slide seat 112 slides in the closing slide rail 113.

[0033] The water tank 106 is filled with water, and the water in the water tank 106 is pumped into the water delivery pipe 105 by the water pump 107 and then enters the horizontal water pipe 205.

[0034] When rainwater enters the water tank 106, the float 108 will float on the water surface. As the water level in the water tank 106 becomes higher and higher, the float 108 and the float rod 109 will rise. The float rod 109 will rise along the sliding seat 110, driving the sliding seat 112 to rise. The sliding seat 112 slides in the closing slide rail 113, thereby driving the closing plate 111 to rotate relative to the water tank 106. When the closing plate 111 rotates to a certain extent, the closing plate 111 closes the water tank 106, and external rainwater can no longer enter the water tank 106.

[0035] like Figure 5-Figure 7 As shown, the closing device includes a photovoltaic panel 202 fixedly mounted on a photovoltaic seat 201, a bidirectional electric cylinder 211 fixedly mounted on the photovoltaic seat 201, a cleaning box 203 fixedly mounted on the two output ends of the bidirectional electric cylinder 211, a light sensor 207 and a large sliding block 210 fixedly mounted on one of the cleaning boxes 203, a rain sensor 208 and a small sliding block 209 fixedly mounted on the other cleaning box 203, the small sliding block 209 is slidably mounted with the large sliding block 210, and a water spraying mechanism and a wiping mechanism are provided on the cleaning box 203.

[0036] like Figure 5-Figure 7As shown, the water spraying mechanism includes a pipe bracket 204 fixedly mounted on the cleaning box 203, a horizontal water pipe 205 fixedly mounted on the pipe bracket 204, the horizontal water pipe 205 is fixedly mounted with the water supply pipe 105, a plurality of flushing pipes 206 are fixedly mounted on the horizontal water pipe 205, and a nozzle 216 is fixedly mounted on the flushing pipe 206.

[0037] like Figure 5-Figure 7 As shown, the wiping mechanism includes a slide cylinder 212 and a movable track 213 fixedly mounted on the cleaning box 203, a rag rack 214 is slidably mounted on the movable track 213, a rag piece 215 is fixedly mounted on the rag rack 214, the rag rack 214 is connected to the slide cylinder 212, and the slide cylinder 212 drives the rag rack 214 to slide along the movable track 213.

[0038] like Figure 3-Figure 7 As shown, a controller is provided on the base plate 101, and the controller is electrically connected to the light sensor 207, the sensor 114, the bidirectional electric cylinder 211, the slide cylinder 212, the water pump 107 and the rain sensor 208. The rain sensor 208 has a higher priority than the light sensor 207. When the rain sensor 208 detects rain and the closing plate 111 is not closed, the cleaning box 203 opens.

[0039] When the light sensor 207 detects sunlight, the two-way electric cylinder 211 extends and drives the two cleaning boxes 203 to move outward, so that the photovoltaic panel 202 is exposed, and the photovoltaic panel 202 generates photovoltaic power. When the light sensor 207 does not detect sunlight, the two-way electric cylinder 211 contracts, driving the cleaning box 203 to slide inward, and the cleaning box 203 closes the photovoltaic panel 202. At this time, the photovoltaic panel 202 can be cleaned, and the water entering the horizontal water pipe 205 is sprayed onto the surface of the photovoltaic panel 202 through the flushing pipe 206 and the nozzle 216. The slide cylinder 212 drives the rag rack 214 to slide along the moving track 213, and drives the rag piece 215 to scrub the surface of the photovoltaic panel 202 after the water is sprayed. The working frequency of the water spraying mechanism and the wiping mechanism can be set by the controller.

[0040] When the rain sensor 208 detects rain, the two-way electric cylinder 211 extends to drive the two cleaning boxes 203 to move outward, thereby driving the lower fixed frame 301 to move outward. When the closing plate 111 is closed, the sensor 114 transmits a signal to the controller, causing the two-way electric cylinder 211 to contract and close the cleaning box 203. When the light sensor 207 detects sunlight, the cleaning box 203 opens again.

[0041] like Figure 8-Figure 10As shown, the collecting device includes an ejection slide column 310 fixedly installed in the lower fixed frame 301, an outer push rod 303 is slidably installed on the ejection slide column 310, an ejection spring 311 is arranged between the outer push rod 303 and the lower fixed frame 301, a filter bucket 302 is fixedly installed on the water tank 106, a switch plate 304 is slidably installed on the filter bucket 302, a slide column 306 is fixedly installed on the filter bucket 302, the switch plate 304 and the slide column 306 are slidably installed, a slide column spring 307 is arranged between the switch plate 304 and the slide column 306, a small push plate 305 is fixedly installed on the switch plate 304, the outer push rod 303 cooperates with the small push plate 305, and the elastic force of the ejection spring 311 is greater than the elastic force of the slide column spring 307.

[0042] like Figure 8-Figure 10 As shown, an upper filter plate 309 and a lower filter plate 308 are provided in the filter bucket 302. The upper filter plate 309 is used to filter large debris such as leaves, etc., and the lower filter plate 308 is used to finely filter rainwater.

[0043] When the rain sensor 208 controls the cleaning box 203 to open, the cleaning box 203 slides outward and pushes the outer push rod 303 to slide outward through the lower fixed frame 301 and the push spring 311, thereby pushing the small push plate 305 and the switch plate 304 to slide outward, and the switch plate 304 slides along the slide column 306, and the slide column spring 307 is compressed. After the switch plate 304 is opened, rainwater can enter the filter bucket 302, and large debris such as leaves are filtered through the upper filter plate 309, and the rainwater is filtered through the lower filter plate 308. The filtered rainwater enters the water tank 106.

[0044] The working principle of the photovoltaic panel automatic cleaning device disclosed in the present invention is as follows: when the light sensor 207 detects sunlight, the controller controls the two-way electric cylinder 211 to extend and drive the two cleaning boxes 203 to move outward, so that the photovoltaic panel 202 is exposed and the photovoltaic panel 202 performs photovoltaic power generation; when the light sensor 207 does not detect sunlight, the two-way electric cylinder 211 contracts and drives the cleaning box 203 to slide inward, and the cleaning box 203 closes the photovoltaic panel 202; the controller controls the water pump 107 to pump the water in the water tank 106 into the water delivery pipe 105 through the water pump 107 and then enters the horizontal water pipe 205. The water entering the horizontal water pipe 205 is sprayed onto the surface of the photovoltaic panel 202 through the flushing pipe 206 and the nozzle 216; the controller controls the slide cylinder 212 to drive the rag rack 214 to slide along the moving track 213, and drives the rag sheet 215 to scrub the surface of the photovoltaic panel 202 after the water is sprayed. When the rain sensor 208 detects rain, the controller controls the two-way electric cylinder 211 to extend and drive the two cleaning boxes 203 to move outward. The cleaning boxes 203 slide outward through the lower fixed frame 301 and the push spring 311 to push the outer push rod 303 to slide outward, thereby pushing the small push plate 305 and the switch plate 304 to slide outward. The switch plate 304 slides along the sliding column 306, and the sliding column spring 307 is compressed. After the switch plate 304 is opened, rainwater can enter the filter bucket 302, and large debris such as leaves are filtered through the upper filter plate 309, and the rainwater is filtered through the lower filter plate 308. The filtered rainwater enters the water tank 106. When rainwater enters the water tank 106, the float 108 will float on the water surface. As the water level in the water tank 106 increases, the float 108 and the float rod 109 will rise. The float rod 109 will rise along the sliding seat 110, driving the sliding seat 112 to rise. The sliding seat 112 slides in the closing slide rail 113, thereby driving the closing plate 111 to rotate relative to the water tank 106. When the closing plate 111 rotates to a certain extent, the closing plate 111 closes the water tank 106, and the external rainwater can no longer enter the water tank 106. When the closing plate 111 is closed, the sensor 114 transmits a signal to the controller, causing the two-way electric cylinder 211 to contract and close the cleaning box 203. When the light sensor 207 detects sunlight, the cleaning box 203 opens again.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
