Abstract
Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic power generation panel technology, and specifically relates to a cleaning device for photovoltaic power generation panels. Background Technology
[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They are mainly composed of solar cells, glass, and backsheets. They generate electricity using the photovoltaic effect of semiconductors and are characterized by being clean and renewable. They are mainly used for grid-connected power generation to provide electricity for homes and businesses; they can also be used in off-grid scenarios, such as power supply in remote areas and traffic lights; and they can be integrated with buildings to form building-integrated photovoltaic systems, which can be applied to roofs, walls, etc., to achieve energy self-sufficiency.
[0003] Currently, Chinese utility model patent CN221467652U discloses a cleaning device for photovoltaic panels, belonging to the field of photovoltaic panel technology. This cleaning device includes a base, a supporting pole, a connecting diagonal rod, a supporting diagonal rod, a positioning frame, a cleaning mechanism, a first drive motor, a second drive motor, and a water tank. The top of the base is movably connected to the bottom of the supporting pole, the top of the supporting pole is movably connected to the bottom of the connecting diagonal rod, the top of the connecting diagonal rod is fixedly connected to the positioning frame, and the positioning frame is movably connected to the cleaning mechanism. The first drive motor is located at the bottom of the base, and the second drive motors are located at both ends of the cleaning mechanism. The base is composed of multiple splicing seats, each with a length consistent with the width of the photovoltaic panel. This solution solves the problem of low cleaning efficiency in existing photovoltaic panel cleaning devices, which cannot clean a row of photovoltaic panels at once.
[0004] Although the above-mentioned utility model solves the problem that existing photovoltaic panel cleaning devices cannot clean a row of photovoltaic panels at once, resulting in low cleaning efficiency, it cannot achieve a good water removal effect on the surface of the device. As a result, the surface of the device remains dripping for a period of time after use. When the staff needs to stop working due to other issues, they cannot put the device away in time. It would be quite troublesome to use manual wiping to prevent dripping. Utility Model Content
[0005] The purpose of this invention is to provide a cleaning device for photovoltaic panels, the advantage of which is to remove water from the cleaning structure.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning device for photovoltaic power generation panels, comprising a connecting plate, with support shells welded to both sides of the upper end of the connecting plate, an installation block welded to one side of the upper end of the connecting plate, a rotating rod welded inside the installation block, a push handle rotatably connected to the surface of the rotating rod, a second rotating shaft rotatably connected to both sides of the installation block, a rotating shell fixedly connected to one side of the second rotating shaft, a sliding groove and a threaded hole opened on the surface of the rotating shell, three sets of extrusion rods welded inside the rotating shell, and a push rod slidably connected inside the sliding groove.
[0007] Using the above technical solution: the push handle can rotate on the surface of the rotating rod, which facilitates the movement of the pushing device. When the push rod moves forward and squeezes the inner wall of the slide groove, it will cause the rotating shell to rotate using the second rotating shaft, thereby driving the squeezing rod to rotate. One end of the squeezing rod is inclined, which facilitates the insertion of the lever into the inside of the rotating shell. The squeezing rod can squeeze the PVA water-absorbing sponge on the surface of the lever, thereby achieving the dehydration effect. The squeezed water will flow out from the inside of the threaded hole.
[0008] The present invention is further configured such that a fixing plate is welded to the upper ends of both sides of the connecting plate, a sliding shell is welded to one side of the fixing plate, a sliding rod is slidably connected inside the sliding shell, and a push rod is welded to the surface of the sliding rod.
[0009] With the above technical solution, the slide bar can slide inside the slide housing, and the push rod can limit the sliding of the slide bar.
[0010] The present invention is further configured such that a first rotating shaft is rotatably connected to one end of the slide rod, a bent plate is fixedly connected to one end of the first rotating shaft, and a lever is welded to one side of the bent plate.
[0011] Using the above technical solution: the lever will rotate with the bending plate on the first rotating shaft surface. The surface of the lever will be covered with a PVA water-absorbing sponge. When the lever rotates into the inside of the cleaning wheel, the bristles on the surface of the cleaning brush will be squeezed and bent by the lever as the cleaning wheel rotates, thereby shaking off the water on the surface of the bristles. The PVA water-absorbing sponge can absorb the moisture on the surface of the bristles.
[0012] The present invention is further configured such that two sets of positioning holes are provided on one side of the curved plate, and an installation plate is welded to one end of the sliding shell.
[0013] The above technical solution is adopted: the positioning hole is used for positioning the positioning rod.
[0014] The present invention is further configured such that a positioning rod is slidably connected inside the mounting plate, and a tension spring is sleeved on the surface of the positioning rod. Both ends of the tension spring are connected between the mounting plate and the positioning rod through spring fixing members, and the positioning rod and the positioning hole are detachably connected.
[0015] Using the above technical solution: the tension spring will pull the positioning rod to position it inside the appropriate positioning hole, thereby limiting the rotation of the bent plate.
[0016] The present invention is further configured such that a motor is bolted inside one set of the support housings, and a synchronous pulley is provided inside the other set of the support housings and at the output end of the motor. One set of synchronous pulleys is rotatably connected to the other set of the support housings, and the other set of synchronous pulleys is fixedly connected to the motor. A synchronous belt is connected between the two sets of synchronous pulleys for transmission. A cleaning wheel is bolted to one end of each set of synchronous pulleys, and the cleaning wheel is rotatably connected to the connecting plate.
[0017] The above technical solution is adopted: when the motor is running, it will drive one set of synchronous pulleys to rotate. Due to the use of the synchronous belt, it will drive the other set of synchronous pulleys to rotate synchronously, thereby driving the two sets of cleaning wheels to rotate and clean the surface of the photovoltaic panel.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. When cleaning the photovoltaic panels, as the cleaning wheel continues to rotate with the motor, the bristles on the surface of the cleaning wheel will be rotated by the lever, and the PVA water-absorbing sponge on the surface of the lever will absorb the water. This can automatically remove water from the surface of the bristles, saving the trouble of manual water removal and the time spent on natural drying. This makes it easy to store the device inside the warehouse, so that too much water will flow inside the room.
[0020] 2. It can also remove moisture from the PVA absorbent sponge on the surface of the lever, saving the trouble of manually wringing it out. This also prevents the PVA absorbent sponge from becoming moldy and damaged due to not being cleaned for a long time, thus achieving the effect of multiple uses. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] refer to Figure 1-3 A cleaning device for photovoltaic panels includes a connecting plate 1. Support shells 8 are welded to both sides of the upper end of the connecting plate 1. A mounting block 2 is welded to one side of the upper end of the connecting plate 1. A rotating rod 3 is welded inside the mounting block 2.

One set of synchronous pulleys 6 is rotatably connected to the other set of support housings 8, and the other set of synchronous pulleys 6 is fixedly connected to the motor 5. The two sets of synchronous pulleys 6 are connected by a synchronous belt 7 for transmission. One end of each set of synchronous pulleys 6 is bolted to a cleaning wheel 9, and the cleaning wheel 9 is rotatably connected to the connecting plate 1.
[0028] Example 2:
[0029] refer to Figure 2A fixing plate 1001 is welded to the upper ends of both sides of the connecting plate 1. A sliding shell 1002 is welded to one side of the fixing plate 1001. A sliding rod 1003 is slidably connected inside the sliding shell 1002, and a push rod 1101 is welded to the surface of the sliding rod 1003. A first rotating shaft 1007 is rotatably connected to one end of the sliding rod 1003. A bent plate 1009 is fixedly connected to one end of the first rotating shaft 1007. A lever 1008 is welded to one side of the bent plate 1009. Two sets of positioning holes 1010 are opened on one side of the bent plate 1009. A mounting plate 1006 is welded to one end of the sliding shell 1002. A positioning rod 1004 is slidably connected inside the mounting plate 1006. A tension spring 1005 is sleeved on the surface of the positioning rod 1004. Both ends of the tension spring 1005 are connected between the mounting plate 1006 and the positioning rod 1004 through spring fixing parts. The positioning rod 1004 and the positioning hole 1010 are detachably connected.
[0030] Brief description of usage: The push handle 4 can rotate on the surface of the rotating rod 3, facilitating the movement of the device. When the motor 5 runs, it drives one set of synchronous pulleys 6 to rotate. Due to the use of the synchronous belt 7, it also drives the other set of synchronous pulleys 6 to rotate synchronously, thereby driving the two sets of cleaning wheels 9 to rotate and clean the surface of the photovoltaic panel. When it is necessary to remove water from the bristles of the cleaning wheel 9, the lever 1008 can be positioned inside the bristles. The tension spring 1005 can pull the positioning rod 1004 to be positioned inside the positioning hole 1010, thus positioning the bent plate 1009 and preventing it from rotating arbitrarily. The circular structure at one end of the positioning rod 1004 is detachable and has a threaded connection, so the tension spring 1005 can be replaced when it is not in use. The surface of the lever 1008 is covered with PVA absorbent sponge. As the cleaning wheel 9 rotates, the bristles on the surface of the cleaning brush are squeezed and bent by the lever 1008, thereby shaking off the water from the surface of the bristles. The absorbent sponge absorbs moisture from the surface of the brush bristles. After dewatering stops, the PVA absorbent sponge will absorb a certain amount of moisture. Then, the lever 1008 is pulled outward using the slide rod 1003, pulling the lever 1008 out from inside the brush bristles on the surface of the cleaning wheel 9. At this time, the positioning rod 1004 can be pulled out from inside the positioning hole 1010, and the bending plate 1009 can be rotated using the first rotating shaft 1007. When rotated 180 degrees, the positioning rod 1004 will reposition the bending plate 1009. Then, the lever 1008 and the PVA... The absorbent sponge is inserted inside the rotating shell 1103. As the push lever 1008 moves inside the sliding shell 1002 via the slide rod 1003, the push rod 1101 moves forward with the slide rod 1003 and squeezes the inner wall of the slide groove 1105. This causes the rotating shell 1103 to rotate via the second rotating shaft 1102, thereby driving the squeezing rod 1106 to rotate. One end of the squeezing rod 1106 is beveled, which facilitates the insertion of the lever 1008 inside the rotating shell 1103. The squeezing rod 1106 will squeeze the PVA absorbent sponge on the surface of the lever 1008, thereby achieving the dehydration effect. The squeezed water will flow out from the threaded hole 1104.
[0031] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
