[0032] As shown in the appended Figure 1 to the appended Figure 6As shown in the figure, the utility model provides a cleaning device for a photovoltaic module, which includes a mounting base 1, and a photovoltaic panel is installed on the top of the mounting base 1; it also includes a cleaning component, which is composed of a driving mechanism 2, a cleaning mechanism 3 and a reversing mechanism 4. The driving mechanism 2 includes a driving motor 201 and a driving screw 202. The driving motor 201 is fixedly installed on the side of the mounting base 1, and the driving screw 202 is rotatably connected to the top of the mounting base 1. One end of the rotating shaft of the driving motor 201 is in transmission connection with one end of the rod body of the driving screw 202; the cleaning mechanism 3 includes a moving seat 301, a spraying rod 302 and a wiping block 303. The moving seat 301 is inserted into the interior of the mounting base 1, and the spraying rod 302 is fixedly installed on the side of the moving seat 301. The wiping block 303 is fixedly installed on the side of the moving seat 301, and the bottom of the wiping block 303 abuts against the top of the photovoltaic panel on the top of the mounting base 1. The driving screw 202 is screwed into the interior of the moving seat 301 through the rod body thread; there are two spraying rods 302 on the side of the moving seat 301, and the two spraying rods 302 are symmetrically arranged on both sides of the wiping block 303. There are two selection channels 3011 inside the moving seat 301, and the two selection channels 3011 are respectively communicated with the two spraying rods 302, and the two selection channels 3011 are connected to the external water supply pipeline; the reversing mechanism 4 includes a control gear 401, a reversing seat 402 and an opening and closing seat 403. The control gear 401 is rotatably connected to the interior of the moving seat 301, the reversing seat 402 is inserted into the interior of the moving seat 301, the opening and closing seat 403 is inserted into the interior of the moving seat 301, and the rod body of the driving screw 202 passes through the interior of the control gear 401; the driving mechanism 2 can drive the cleaning mechanism 3 to reciprocate on the top of the mounting base 1. When the driving motor 201 rotates, it can drive the driving screw 202 to rotate. When the driving screw 202 rotates, it can drive the moving seat 301 to move on the top of the mounting base 1 through the rod body thread. Thus, by switching the forward and reverse rotation of the driving motor 201, the reciprocating movement of the cleaning mechanism 3 on the top of the mounting base 1 can be realized, and the degree of automation is high; the cleaning mechanism 3 can realize the operations of spraying water to moisten, flushing and wiping and cleaning the photovoltaic panel. The water supply pipeline can supply water into the interior of the selection channel 3011. After the selection channel 3011 supplies the water to the corresponding spraying rod 302 through the opened control channel 4031, the spraying rod 302 can spray water to moisten and flush the photovoltaic panel. At the same time, when the moving seat 301 moves, the wiping block 303 can wipe and clean the surface of the photovoltaic panel, which is convenient and flexible to use.

[0033] The driving motor 201 is electrically connected to an external power supply and a control device. Its specific structure and working principle are mature existing technologies and will not be elaborated here.

[0034] In the embodiment of the present utility model, the plate body of the opening and closing seat 403 is in an "L" shape, and two control channels 4031 are arranged inside the vertical plate of the opening and closing seat 403. When the moving seat 301 moves, only one control channel 4031 coincides with one of the selection channels 3011. During use, under the control of the reversing mechanism 4, only the spray rod 302 on the side towards the forward direction sprays water for cleaning each time, that is, it ensures that the wiping block 303 will always be wetted by spraying water in front of it when following the movement of the moving seat 301. Here, the forward movement is taken as an example of the initial state. When the moving seat 301 moves forward, at this time, the driving screw rod 202 rotates forward. A synchronizing block 4011 is arranged inside the control gear 401, and a synchronizing groove 2021 is arranged inside the driving screw rod 202. The synchronizing block 4011 is inserted into the synchronizing groove 2021. When the driving screw rod 202 rotates forward, the synchronizing groove 2021 can drive the control gear 401 to rotate forward synchronously through the synchronizing block 4011. When the control gear 401 rotates forward, it can move the reversing seat 402 to one side through the control rack 4021, and after losing the transmission, the control gear 401 can still position the reversing seat 402 through the control rack 4021 when continuously rotating forward. A reversing rod 4023 is arranged at the bottom of the reversing seat 402, and an inclined reversing groove 4032 is arranged inside the horizontal plate of the opening and closing seat 403. The reversing rod 4023 is inserted into the reversing groove 4032. After the reversing seat 402 is moved to one side, the reversing rod 4023 can drive the opening and closing seat 403 to move through the reversing groove 4032. After that, the control channel 4031 in the forward direction coincides with the selection channel 3011, and the other group of control channels 4031 and the selection channel 3011 are misaligned. Thus, only the spray rod 302 in the forward direction can obtain water source to spray and wash the photovoltaic panel, and at the same time, it is also convenient for the wiping block 303 to wipe the photovoltaic panel, avoiding damage to the photovoltaic panel.

[0035] In the embodiment of the present utility model, a control rack 4021 is provided at the top of the reversing seat 402. The control rack 4021 is engaged and driven with the teeth of the control gear 401. A balance spring 4022 is provided on the side of the reversing seat 402, and both ends of the balance spring 4022 are fixedly connected to the side of the reversing seat 402 and the inside of the moving seat 301 respectively. There are two balance springs 4022, and the two balance springs 4022 are symmetrically arranged on both sides of the reversing seat 402. During use, when the driving motor 201 drives the driving screw 202 to reverse, at this time the moving seat 301 is in a retracted state. When the driving screw 202 reverses, the synchronous groove 2021 can drive the control gear 401 to reverse synchronously through the synchronous block 4011. Under the action of the two balance springs 4022, the control rack 4021 of the reversing seat 402 is pressed back to the bottom of the control gear 401 again, so that the control gear 401 can dial the reversing seat 402 to the other side. At this time, the original coincident control channel 4031 and the selection channel 3011 will be misaligned, and another group of control channels 4031 and selection channels 3011 will coincide. Thus, the spray rod 302 in the retracting direction can obtain water supply to realize the operation of flushing and cleaning the photovoltaic panel during retraction. The switching is fully automated and does not require manual intervention, which is convenient and flexible to use.

[0036] Specific usage method and function of this embodiment:

[0037] In the present utility model, when it is necessary to clean the photovoltaic panel, only the power supply of the driving motor 201 needs to be turned on. Under the action of the control device, the driving motor 201 can rotate forward and backward regularly, thereby driving the cleaning mechanism 3 to reciprocate to realize the cleaning operation of the photovoltaic panel. The external water supply device can supply water to the inside of the cleaning mechanism 3 through the water supply pipe. The driving mechanism 2 can drive the cleaning mechanism 3 to reciprocate on the top of the mounting seat 1. When the driving motor 201 rotates, it can drive the driving screw 202 to rotate. When the driving screw 202 rotates, it can drive the moving seat 301 to move on the top of the mounting seat 1 through the rod body thread. Thus, by switching the forward and reverse rotation of the driving motor 201, the reciprocating movement of the cleaning mechanism 3 on the top of the mounting seat 1 can be realized. The cleaning mechanism 3 can realize the operations of spraying water to wet the photovoltaic panel, flushing, and wiping and cleaning. The water supply pipe can supply water to the inside of the selection channel 3011. After the selection channel 3011 supplies the water to the corresponding spray rod 302 through the opened control channel 4031, the spray rod 302 can spray water to wet and flush the photovoltaic panel. At the same time, when the moving seat 301 moves, the wiping block 303 can wipe and clean the surface of the photovoltaic panel. Under the control of the reversing mechanism 4, only the spray rod 302 on the side facing the forward direction sprays water for cleaning each time, which ensures that the operation of spraying water to wet the surface will always be carried out in front of the wiping block 303 when it follows the moving seat 301. Taking the forward movement as an example in the initial state, when the moving seat 301 moves forward, at this time the driving screw 202 rotates forward. When the driving screw 202 rotates forward, the synchronous groove 2021 can drive the control gear 401 to rotate forward synchronously through the synchronous block 4011. When the control gear 401 rotates forward, it can push the reversing seat 402 to one side through the control rack 4021. And after losing the transmission, the control gear 401 can still position the reversing seat 402 through the control rack 4021 when it continues to rotate forward. After the reversing seat 402 is pushed to one side, the reversing rod 4023 can drive the opening and closing seat 403 to move through the reversing groove 4032. After that, the control channel 4031 in the forward direction and the selection channel 3011 coincide, and the other group of control channels 4031 and the selection channel 3011 are misaligned. Thus, only the spray rod 302 in the forward direction can obtain water to spray and clean the photovoltaic panel, and at the same time, it is convenient for the wiping block 303 to wipe the photovoltaic panel, avoiding damage to the photovoltaic panel. When the driving motor 201 drives the driving screw 202 to reverse, at this time the moving seat 301 is in the reverse state. When the driving screw 202 reverses, the synchronous groove 2021 can drive the control gear 401 to reverse synchronously through the synchronous block 4011. Under the action of the two balance springs 4022, the control rack 4021 of the reversing seat 402 is pressed back to the bottom of the control gear 401, so that the control gear 401 can push the reversing seat 402 to the other side. At this time, the originally coincident control channel 4031 and the selection channel 3011 will be misaligned, and the other group of control channels 4031 and the selection channel 3011 will coincide.Thus, the injection rod 302 in the backward direction can obtain water source supply to realize the operation of flushing and cleaning the photovoltaic panel when moving backward. The switching is fully automated and does not require human intervention.

[0038] In another embodiment, a soft cleaning sponge is provided at the bottom of the wiping block 303, which can avoid scratching the photovoltaic panel during wiping and further improve the stability of the device.
