Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic cleaning equipment, in particular to a water surface photovoltaic automatic cleaning equipment. BACKGROUND

[0002] In recent years, with the large-scale construction of water surface floating photovoltaic power stations such as "fish-light complementary", the problem of power generation efficiency decay due to pollution has become increasingly prominent. According to the "China Renewable Energy Development Report 2023" and the measured data of multiple hundred-megawatt power stations, the annual average power generation efficiency of floating photovoltaic modules is attenuated by 7% to 12% due to dust accumulation, bird droppings attachment and scale deposition. Among them, scale, rich in calcium and magnesium ions, forms a dense crystalline layer in a dry-wet alternating environment, and its long-term impact on light transmittance even exceeds that of dust.

[0003] In the prior art, the cleaning of the above-mentioned pollution mainly relies on manual boat operation: the operator needs to carry a high-pressure water gun, cleaning agent and a scraper to clean the photovoltaic array piece by piece.

[0004] However, manual cleaning of a single module (2 square meters) takes an average of about 3 minutes, and for a megawatt power station (based on 4000 modules), a single comprehensive cleaning requires continuous operation for more than 20 days, and manual boat operation needs to deal with wind and waves, boat stability and high-voltage equipment leakage risk; the cleaning efficiency is low, the cost is high and there are safety hazards.

[0010] Preferably, the outer side of the downflow groove of the support frame is provided with a second support plate, the inner side of the second support plate is provided with a pressing head, and the pressing head is parallel to the plug-in interface arranged in the middle of the bottom fixed blocking ring of the cleaning assembly.

[0011] Preferably, the top of the water collecting block at the top of the cleaning assembly is provided with a water inlet, and the water inlet is connected with a water pump fixed on the support frame leg through a corrugated hose.

[0012] Preferably, the bottom of the brush at the bottom of the cleaning assembly is in close contact with the surface of the photovoltaic array at the top of the support frame, and when the cleaning assembly slides, the brush can clean the photovoltaic array.

[0013] Preferably, the second telescopic groove arranged in the inner side of the water spraying head of the support frame is provided with a second spring, the top of the second spring is connected with the inner wall of the second telescopic groove, the bottom of the second spring is connected with a telescopic blocking ring, the inner side of the bottom of the telescopic blocking ring is provided as an arc surface, and the second spring can drive the telescopic blocking ring to expand and contract.

[0014] Preferably, one side of the water spraying head is provided with a water inlet hose, and the other end of the water inlet hose is in communication with the water collecting block at the top of the cleaning assembly, so that the water collecting block can supply water to the water spraying head through the water inlet hose.

[0015] Preferably, the bottom of the cleaning assembly is provided with an extrusion plate at both ends, and the bottom of the extrusion plate is provided as an arc surface.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] The automated photovoltaic cleaning equipment proposed in this invention features a support frame placed at an angle on the water surface of the photovoltaic area. When cleaning the photovoltaic array positioned atop the support frame, a lead screw motor is activated, driving the lead screw to rotate. This rotation causes the cleaning component to slide along the lead screw. A limiting rod, slidably connected to the other end of the cleaning component, limits its movement, preventing deviation. Simultaneously, a water pump fixed to the support frame legs is activated, pumping water from the photovoltaic area through a corrugated hose to a water collection block at the top of the cleaning component. The water collection block then supplies water to the spray nozzles at the bottom of the cleaning component via an inlet hose, causing the nozzles to spray water. As the cleaning component slides, it drives the spray nozzles to flush the photovoltaic array. Simultaneously, the sliding motion of the cleaning component activates the brushes at its bottom to clean the photovoltaic array, preventing residual dirt. When the cleaning component reaches the top of the telescopic baffle, the arc surfaces of the extrusion plates at both ends of the bottom of the cleaning component press against the top arc surface of the telescopic baffle, causing the telescopic baffle to retract into the first telescopic groove. After the cleaning component passes the telescopic baffle, the first spring in the first telescopic groove bounces the telescopic baffle back. The height of the telescopic baffle is greater than the gap between the cleaning component and the support frame. At this time, the cleaning component is located above the lower flow channel. At the same time, the extrusion head set on the inner side of the second support plate begins to extrude the water spray head through the insertion interface in the middle of the fixed retaining ring. The water spray head begins to swing through the hinge shaft connected at the top due to the extrusion. The water spray head, through the swing, pushes the telescopic retaining ring into the second telescopic groove through the arc surface at the bottom of the telescopic retaining ring. At this time, the water outlet of the water spray head is aligned with the brush, and the water spray head begins to clean the brush by spraying water to prevent dirt from sticking to the brush. The further rebounding telescopic baffle can block the dirty water, preventing the dirty water from cleaning the brush from splashing onto the photovoltaic array again. Attached Figure Description

[0027] The top four corners of the support frame 1 are provided with first support plates 3. The inner sides of the two sets of first support plates 3 at the top of the support frame 1 are rotatably connected to lead screws 5.

The lead screw motor 4 drives the lead screw 5 to rotate, and the lead screw 5 drives the cleaning component 7 to slide on the lead screw 5 through rotation. Furthermore, the limit rods 6 slidably connected to the other end of the cleaning component 7 begin to limit the cleaning component 7 to prevent it from sliding off-center.

[0028] The support frame 1 has a lower flow groove 10 on one side of the photovoltaic array 2. The support frame 1 has a first telescopic groove 20 on the inner side of the lower flow groove 10. A first spring 21 is provided in the first telescopic groove 20. The bottom of the first spring 21 is connected to the inner wall of the first telescopic groove 20, the top of the first spring 21 is connected to the first spring 21, and the bottom of the first spring 21 is connected to the telescopic retaining ring 19. The top two sides of the telescopic retaining ring 19 are set as arc surfaces. The water spray head 16 starts to swing through the hinge shaft 15 connected at the top by squeezing. The water spray head 16 swings through the arc surface at the bottom of the telescopic retaining ring 19 to squeeze the telescopic retaining ring 19 into the second telescopic groove 24.

[0029] A second support plate 12 is provided on the outer side of the lower flow channel 10 of the support frame 1, and a squeezing head 13 is provided on the inner side of the second support plate 12. The squeezing head 13 is parallel to the insertion interface 22 opened in the middle of the bottom fixing ring 18 of the cleaning component 7. A water inlet 9 is provided on the top of the water collection block 8 at the top of the cleaning component 7. The water inlet 9 is connected to a water pump fixed on the support leg of the support frame 1 through a corrugated hose. The water pump pumps water from the photovoltaic area to the water collection block 8 at the top of the cleaning component 7 through the corrugated hose. The water collection block 8 then supplies water to the water spray head 16 at the bottom of the cleaning component 7 through the water inlet hose 17 connected to the water collection block 8.

[0030] The bottom of the brush 14 at the bottom of the cleaning component 7 is in close contact with the surface of the photovoltaic array 2 at the top of the support frame 1. When the cleaning component 7 slides, the brush 14 can clean the photovoltaic array 2. A second spring 25 is provided in the second telescopic groove 24 opened inside the water spray head 16 of the support frame 1. The top of the second spring 25 is connected to the inner wall of the second telescopic groove 24, and the bottom of the second spring 25 is connected to the telescopic retaining ring 19. The inner side of the bottom of the telescopic retaining ring 19 is set as an arc surface. The second spring 25 can drive the telescopic retaining ring 19 to extend and retract. A water inlet hose 17 is provided on one side of the water spray head 16, and the other end of the water inlet hose 17 is connected to the cleaning component 7. The water collection block 8 at the top of the cleaning component 7 is connected, allowing the water collection block 8 to supply water to the spray head 16 through the water inlet hose 17; the bottom ends of the cleaning component 7 are provided with extrusion plates 23, and the bottom sides of the extrusion plates 23 are set as arc surfaces; the arc surfaces of the extrusion plates 23 at the bottom ends of the cleaning component 7 extrude the top arc surface of the telescopic baffle 11, causing the telescopic baffle 11 to retract into the first telescopic groove 20. After the cleaning component 7 passes the telescopic baffle 11, the first spring 21 in the first telescopic groove 20 will spring back the telescopic baffle 11. The height of the telescopic baffle 11 is greater than the gap between the cleaning component 7 and the support frame 1.

[0031] In actual use, the support frame 1 is placed at an angle on the water surface of the photovoltaic area. When cleaning the photovoltaic array 2 set on top of the support frame 1, the lead screw motor 4 is started, which drives the lead screw 5 to rotate. The rotation of the lead screw 5 drives the cleaning component 7 to slide on the lead screw 5. Furthermore, the limiting rod 6, which is slidably connected to the other end of the cleaning component 7, begins to limit the cleaning component 7 to prevent it from sliding and shifting. At the same time, the water pump fixed on the legs of the support frame 1 is started, which causes the water in the photovoltaic area to be pumped through waves. The flexible hose is drawn into the water collection block 8 at the top of the cleaning component 7. The water collection block 8 then supplies water to the water spray head 16 at the bottom of the cleaning component 7 through the water inlet hose 17 connected to the water collection block 8, causing the water spray head 16 to start spraying water. At this time, as the cleaning component 7 slides, it drives the water spray head 16 to spray water and rinse the photovoltaic array 2. While the cleaning component 7 is sliding, it also drives the brush 14 at the bottom of the cleaning component 7 to clean the photovoltaic array 2, preventing dirt from remaining on the photovoltaic array 2. When the cleaning component 7 reaches the top of the telescopic baffle 11, the cleaning component... The arc surfaces of the extrusion plates 23 at both ends of the bottom of the 7th section press against the top arc surface of the telescopic baffle 11, causing the telescopic baffle 11 to retract into the first telescopic groove 20. After the cleaning component 7 passes the telescopic baffle 11, the first spring 21 in the first telescopic groove 20 springs the telescopic baffle 11 back. The height of the telescopic baffle 11 is greater than the gap between the cleaning component 7 and the support frame 1. At this time, the cleaning component 7 is located above the lower flow channel 10. At the same time, the extrusion head 13 provided on the inner side of the second support plate 12 begins to press against the top arc surface of the telescopic baffle 11 through the insertion interface 22 in the middle of the fixed retaining ring 18. The water spray head 16 is squeezed, and the water spray head 16 begins to swing through the hinge shaft 15 connected at the top. The water spray head 16 swings through the arc surface at the bottom of the telescopic baffle 19, squeezing the telescopic baffle 19 into the second telescopic groove 24. At this time, the water outlet of the water spray head 16 is aligned with the brush 14, and the water spray head 16 begins to clean the brush 14 by spraying water to prevent dirt from sticking to the brush 14. The further rebounding telescopic baffle 11 can block the dirty water and prevent the dirty water used to clean the brush 14 from splashing onto the photovoltaic array 2 again.
