Description

Technical Field

[0001] The present invention relates to the technical field of power generation panel cleaning devices, and in particular to a photovoltaic power generation device and method with a self-cleaning effect. Background Art

[0002] Photovoltaic power generation devices are photovoltaic panels, also known as solar panels, which are devices that directly convert solar energy into electrical energy. The photovoltaic cells on their surface are protected by tempered glass panels and are widely used in residential, commercial and industrial fields. During the use of such photovoltaic panels, their power generation efficiency is greatly affected by the cleanliness of the surface. Pollutants such as dust, bird droppings, and leaves will block light and reduce the photoelectric conversion efficiency. Therefore, keeping the surface of photovoltaic panels clean is crucial to ensure their efficient operation.

[0003] At present, there are two ways to clean photovoltaic panels. One is manual cleaning, which uses water and brushes to manually clean the surface of the photovoltaic panel. Although this method is effective, it is time-consuming and labor-intensive, and difficult to implement in large-scale photovoltaic power stations. The other is mechanical cleaning, which uses automatic or semi-automatic cleaning equipment, such as mechanical brushes, water spray devices, etc. For mechanical cleaning, the usual operating method is to directly add a cleaning component on the top of the photovoltaic panel. When cleaning is required, the cleaning component is driven by a motor to move and clean the surface of the photovoltaic glass panel.

[0004] However, when mechanical cleaning methods are actually used, too many automatic cleaning components will occupy a certain amount of lighting space on the top of the photovoltaic panel, affecting the actual photoelectric conversion rate of the photovoltaic panel. In addition, when encountering typhoons and other weather conditions, domestic garbage such as plastic bags may be blown onto the cleaning components by the wind, which will directly affect the subsequent cleaning operations. In severe cases, the photovoltaic panel may be overturned and damaged due to uneven wind force.

[0005] Therefore, how to provide a photovoltaic power generation device and method with a self-cleaning effect is an urgent problem that those skilled in the art need to solve. Summary of the invention

[0009] The bite moving component is arranged on the output shaft of the active motor, and the active motor drives the cleaning roller to move horizontally on the surface of the photovoltaic panel through the bite moving component.

[0010] Furthermore, the second side swing mechanism also includes a first placement plate and a second placement plate, and a limiting slide groove is respectively opened on the top of one side of the first placement plate and the second placement plate, and a limiting slide rail is fixed at the bottom of the photovoltaic panel. The first placement plate and the second placement plate are slidably connected on the surface of the limiting slide rail through the limiting slide groove, and the active motor is fixed on one side of the first placement plate.

[0011] Furthermore, the meshing moving component includes a main tooth and a transmission tooth, the transmission tooth meshes above one side of the main tooth, the top of the transmission tooth meshes with the meshing rail groove, and the meshing rail groove is opened on the bottom surface of the photovoltaic panel.

[0012] Furthermore, the main teeth and the transmission teeth are rotatably mounted between the first mounting plate and the second mounting plate through the side plate frame, and the output shaft of the active motor movably passes through the first mounting plate, the side plate frame, the main teeth and the second mounting plate.

[0013] Furthermore, a single-sided groove is opened through the inner side of the main tooth, and a cam is fixedly connected to the output shaft of the active motor near the inner side of the single-sided groove. The cam and the single-sided groove are rotationally conflicted, and the rotational conflict angle is greater than one hundred and eighty degrees. The active motor drives the main tooth to rotate through the cam.

[0014] Furthermore, the first side-swing mechanism includes a micro motor and a mounting frame, the three groups of water gun heads are respectively fixed on the surface of the mounting frame, and the two sides of the mounting frame are rotatably connected to the photovoltaic panel through axle pins.

[0015] Furthermore, one end of the shaft pin is fixed to the vortex gear, the output shaft of the micro motor is engaged with the vortex gear through the vortex rod, and the micro motor is fixed to one side of the photovoltaic panel.

[0016] Furthermore, the side tilting mechanism includes a screw, a transmission block and a support rod, the screw thread passes through the transmission block, and both ends of the screw are rotatably arranged inside the L base through shaft sleeves, the top of the transmission block is movably connected to the support rod through a side plate, and the top of the support rod is movably connected to the bottom of the photovoltaic panel through a movable side frame.

[0017] Furthermore, one side of the screw rod is connected to the output shaft of the transmission motor through a pair of meshing teeth. The transmission motor is fixed under the L base. A slide rail is provided at a position of the L base close to the transmission block. The transmission block slides laterally inside the L base.

[0018] A self-cleaning method for a photovoltaic power generation device, the specific steps are as follows:

[0019] S1. First, the transmission motor is driven. The transmission motor directly drives the screw inside the L base to rotate through the meshing gear group. At this time, the transmission block is restricted by the inner slide rail of the L base to cause horizontal thread transmission, driving the lower side of the support rod to move to one side. At this time, the top of the support rod will pull one side of the photovoltaic panel downward through the movable side frame to tilt and swing, thereby changing the actual orientation angle of the photovoltaic panel;

[0020] S2, then by controlling and driving the two sets of active motors at the bottom of the photovoltaic panel, the output shaft of the active motor first directly drives the connecting rod to rotate through the friction ring, and the top of the connecting rod and the side connecting rod of the cleaning roller move, so that the cleaning roller can be synchronously driven to rotate with the output shaft of the active motor as the axis, so as to drive the cleaning roller to rotate from the bottom of the photovoltaic panel to the top of the photovoltaic panel, and the rotation angle is greater than 180 degrees, and then the cleaning roller will fit with the top surface of the photovoltaic panel, and the connecting rod can no longer drive the cleaning roller to rotate, and the continuous rotation effect of the active motor will force the friction ring to rotate in the shaft hole below the connecting rod, and a pulley is fixed at one end of the active motor and the cleaning roller, and the pulleys are driven by a transmission belt, so that the active motor can normally drive the cleaning roller to rotate around its own axis through the transmission effect of the transmission belt to perform a cleaning operation;

[0021] S3. When the active motor drives the cleaning roller to swing in the circle, the cam fixed on the surface of the active motor is synchronously driven to rotate inside the single-sided groove until the protruding position of the cam contacts the concave position of the single-sided groove. At this time, the rotation effect of the active motor will synchronously drive the main teeth to rotate. The main teeth and the transmission teeth are meshed with each other and are restricted to rotate between the first placement plate and the second placement plate through the side plate frame, and the transmission teeth are meshed with the meshing rail grooves on the bottom surface of the photovoltaic panel. At this time, the rotation of the transmission teeth will drive the first placement plate and the second placement plate to move horizontally at the bottom as a whole, and synchronously drive the cleaning roller to move and clean the top surface of the photovoltaic panel. The first placement plate and the second placement plate are stabilized by the limiting slide rails and the photovoltaic panel is stabilized, thereby achieving the effect of alignment first and then cleaning.

[0022] S4. When the active motor drives the cleaning roller to move and clean one side of the photovoltaic panel through the second side swing mechanism, three groups of water gun heads are installed on the other side of the photovoltaic panel through the mounting frame. The two sides of the mounting frame are rotated at the end positions of the photovoltaic panel through the axle pins. When the micro motor is driven, the shaft on the output shaft of the micro motor engages with the vortex gear to make the vortex gear rotate. The vortex gear is fixed by the axle pin, so that the axle pin can drive the mounting frame to swing, thereby driving the three groups of water gun heads to swing from the bottom of the photovoltaic panel to the top of the photovoltaic panel and align with the top surface of the photovoltaic panel for flushing.

[0023] The beneficial effects of the present invention are:

[0024] The present invention provides a support rod, which can drive the transmission block to move on the surface of the screw rod through the screw rod in a rotating state after being driven by the transmission motor, so as to pull one side of the photovoltaic panel to swing downward through the support rod, thereby changing the original horizontal placement state of the photovoltaic panel. On the one hand, it helps to increase the area of ​​both sides of the photovoltaic panel, thereby facilitating the flipping of the subsequent cleaning device, so that when in normal use, the plurality of photovoltaic panels can maintain a relatively compact distribution state. On the other hand, the inclined posture helps to carry out the subsequent cleaning operation, and facilitates the cleaning of stains and garbage from the surface of the photovoltaic panel.

[0025] The present invention fixes a transmission belt at one end of the active motor output shaft, and the active motor drives the cleaning roller to rotate on the surface above the photovoltaic panel through the transmission belt, thereby cooperating with the tempered glass on the surface of the photovoltaic panel to clean the tempered glass on the surface of the photovoltaic panel to prevent scratching of the surface glass of the photovoltaic panel. One side of the active motor output shaft is dampedly connected to the connecting rotating rod through a friction ring. The damping effect can normally drive the cleaning roller to flip on one side of the photovoltaic panel. When the cleaning roller is not in use, the cleaning roller can be normally stored under the photovoltaic panel to prevent the situation of blocking light and hanging objects.

[0026] The present invention provides an interlocking moving component, which can first drive the cleaning roller to flip on one side of the photovoltaic panel when driven by the active motor. After the flipping is completed, the cam will interfere with the single-sided groove, thereby driving the main teeth to rotate, and then the transmission teeth rotate to drive the cleaning roller to move horizontally on the surface of the photovoltaic panel to perform a cleaning operation. The whole process is continuous, and compared with the use of traditional cleaning equipment, it meets the two effects of storage and surface cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0040] refer to Figure 1-Figure 7 , including a photovoltaic panel 1, the photovoltaic panel 1 is movably mounted on the top of the L base 2 through a side tilting mechanism 3, three groups of water gun heads 5 are arranged on the top of one end of the photovoltaic panel 1, the three groups of water gun heads 5 are rotatably arranged on the upper and lower sides of one end of the photovoltaic panel 1 through a first side swing mechanism 4, a cleaning roller 6 is arranged on the end of the photovoltaic panel 1 away from the water gun head 5, and two groups of active motors 7 are fixed on the bottom of the photovoltaic panel 1 close to the cleaning roller 6;

[0041] Two sets of second side swing mechanisms 8, the two sets of second side swing mechanisms 8 are respectively arranged at the bottom of the photovoltaic panel 1 near the active motor 7, the second side swing mechanism 8 includes a transmission belt 81 and a connecting rod 89, the upper and lower sides of the connecting rod 89 are respectively movably connected to the cleaning roller 6 and the output shaft of the active motor 7, the active motor 7 drives the cleaning roller 6 to rotate at one end of the photovoltaic panel 1 through the connecting rod 89, the ends of the active motor 7 and the cleaning roller 6 are respectively fixedly connected to the pulleys, and the two sets of pulleys are connected by the transmission belt 81, the active motor 7 drives the cleaning roller 6 to rotate at the top of the photovoltaic panel 1 through the transmission belt 81, and the friction ring 88 is used to damp the rotation between the connecting rod 89 and the output shaft of the active motor 7;

[0042] The engaging moving component 82 is arranged on the output shaft of the active motor 7 , and the active motor 7 drives the cleaning roller 6 to move horizontally on the surface of the photovoltaic panel 1 through the engaging moving component 82 .

[0043] In this embodiment, the photovoltaic panel 1 can perform a unilateral rollover effect on the top of the L base 2 through the side tilting mechanism 3, so that the photovoltaic panel 1 presents a certain tilt angle between the top of the L base 2 and the ground. This effect can provide a subsequent flipping space for the cleaning roller 6 and the three groups of water gun heads 5 under the photovoltaic panel 1, so that the cleaning roller 6 and the water gun head 5 are normally brought to the position above the photovoltaic panel 1 to clean the glass plate on the top surface of the photovoltaic panel 1. Secondly, the flipping effect provides a larger activity space on both sides of the photovoltaic panel 1 to meet the flipping operation of the water gun head 5 and the cleaning roller 6. It is suitable for a small site and a relatively compact array arrangement of multiple groups of photovoltaic panels 1 to solve the problem of difficulty in setting up cleaning devices between the photovoltaic panels 1.

[0044] In addition, the upper and lower sides of the connecting rod 89 in the second side swing mechanism 8 are respectively movably connected to the side connecting rod of the cleaning roller 6 and the output shaft of the active motor 7, and the connecting rod 89 and the output shaft of the active motor 7 are connected by a friction ring 88 to achieve a damping connection. In this way, after the active motor 7 is normally driven, the static friction between the friction ring 88 and the connecting rod 89 can drive the connecting rod 89 to move in a circular motion as a whole, thereby driving the cleaning roller 6 to flip from the bottom of the photovoltaic panel 1 to the top of the photovoltaic panel 1. After continuous flipping, the cleaning roller 6 contacts the glass panel of the photovoltaic panel 1. At this time, the connecting rod 89 is restricted by the cleaning roller 6 and cannot continue to rotate. The friction ring 88 realizes the activity effect between the active motor 7 and the connecting rod 89. In actual operation, the friction ring 88 is a movable ring / sleeve structure, and friction plates or other friction materials are used inside and outside, which can be achieved by adjusting the size of the friction force.

[0045] In addition, while the active motor 7 normally drives the cleaning roller 6 to flip and rotate, it can also drive the interlocking moving component 82 to move at a specified position. The interlocking moving component 82 realizes the connection between the active motor 7 and the cleaning roller 6 as a whole and the photovoltaic panel 1. Under the operation of the interlocking moving component 82, the active motor 7 and the cleaning roller 6 are driven to move horizontally on the surface of the photovoltaic panel 1, and cooperate with the rotation effect of the cleaning roller 6 to better clean the top glass plate of the photovoltaic panel 1.

[0046] refer to Figure 5 and Figure 6 The second side swing mechanism 8 also includes a first placement plate 84 and a second placement plate 85. A limiting slide groove 86 is respectively provided on the top of one side of the first placement plate 84 and the second placement plate 85. A limiting slide rail 87 is fixed at the bottom of the photovoltaic panel 1. The first placement plate 84 and the second placement plate 85 are slidably connected on the surface of the limiting slide rail 87 through the limiting slide groove 86, and the active motor 7 is fixed on one side of the first placement plate 84.

[0047] In the present embodiment, a limiting slide groove 86 is provided on the upper side of the first placement plate 84 and the second placement plate 85, and a limiting slide rail 87 is provided on the bottom surface of the photovoltaic panel 1. The limiting slide groove 86 and the limiting slide rail 87 are limited by sliding, so that the first placement plate 84 and the second placement plate 85 can provide a better installation stability effect for the active motor 7 and other subsequent components, and the sliding effect can drive the active motor 7 to move to different positions as a whole.

[0048] refer to Figure 5-Figure 7 The meshing moving assembly 82 includes a main tooth 821 and a transmission tooth 822. The transmission tooth 822 meshes on one side of the main tooth 821. The top of the transmission tooth 822 meshes with the meshing track groove 825. The meshing track groove 825 is provided on the bottom surface of the photovoltaic panel 1. The main tooth 821 and the transmission tooth 822 are respectively rotatably mounted between the first placement plate 84 and the second placement plate 85 through the side plate frame 83. The output shaft of the active motor 7 thus movably passes through the first placement plate 84, the side plate frame 83, the main tooth 821 and the second placement plate 85. A single-sided groove 824 is provided on the inner side of the main tooth 821. A cam 823 is fixedly connected to the output shaft of the active motor 7 near the inner side of the single-sided groove 824. The cam 823 and the single-sided groove 824 are in rotational conflict, and the rotational conflict angle is greater than 180 degrees. The active motor 7 drives the main tooth 821 to rotate through the cam 823.

[0049] In this embodiment, the active motor 7 will simultaneously drive the cam 823 to rotate during the rotation process, and the convex position of the cam 823 can normally rotate in the single-sided groove 824 opened on the inner side of the main tooth 821, and one side of the single-sided groove 824 is in a concave state, so that when the convex position of the cam 823 contacts the concave position, the rotation effect of the active motor 7 can directly drive the main tooth 821 to rotate through the cam 823;

[0050] This effect allows the active motor 7 to first drive the connecting rotating rod 89 to rotate during its rotation, thereby driving the cleaning roller 6 to swing first, so that it fits tightly against the top surface of the photovoltaic panel 1, and then drives the main tooth 821 to rotate to achieve the meshing rotation of the transmission tooth 822. The transmission tooth 822 and the main tooth 821 are stably and movably mounted between the first mounting plate 84 and the second mounting plate 85 on both sides through the side plate frame 83. When the transmission tooth 822 rotates, its upper part is meshed with the meshing rail groove 825 on the bottom surface of the photovoltaic panel 1. The rotation effect can drive the first mounting plate 84 and the second mounting plate 85 to move horizontally as a whole, thereby changing the specific positions of the cleaning roller 6 and the active motor 7, thereby achieving the cleaning operation of the cleaning roller 6 on different positions of the top surface of the photovoltaic panel 1.

[0051] refer to Figure 2 and Figure 4The first side swing mechanism 4 includes a micro motor 41 and a mounting frame 44. Three groups of water gun heads 5 are respectively fixed on the surface of the mounting frame 44. Both sides of the mounting frame 44 are rotatably connected to the photovoltaic panel 1 through axle pins 43. One end of the axle pin 43 is fixed with a vortex 42. The output shaft of the micro motor 41 is engaged with the vortex 42 through a vortex rod. The micro motor 41 is fixed on one side of the photovoltaic panel 1.

[0052] In this embodiment, the first side swing mechanism 4 has the same function as the second side swing mechanism 8, but the first side swing mechanism 4 only provides the water gun head 5 with a swinging and storing effect, specifically: after the micro motor 41 is driven, the vortex 42 can be driven to rotate through the vortex rod on the output shaft, the vortex 42 is fixed to one side of the shaft pin 43, the shaft pin 43 rotates, the shaft pin 43 is fixed to the mounting frame 44, and the mounting frame 44 is driven to rotate, thereby driving the three groups of water gun heads 5 to swing, so that their positions change on one side of the photovoltaic panel 1;

[0053] During actual production and use, the rotation angle between the mounting frame 44 and the photovoltaic panel 1 needs to be met, and the space occupied by the micro motor 41 on one side of the photovoltaic panel 1 needs to be reduced as much as possible, so as to effectively realize the normal swing of the water gun head 5 and provide normal activity space for the connecting rotating rod 89, and the size and specific position installation requirements will not be elaborated in detail.

[0054] refer to Figure 1 and Figure 3 The side tilt mechanism 3 includes a screw rod 33, a transmission block 34 and a support rod 35. The screw rod 33 is threaded through the transmission block 34, and the two ends of the screw rod 33 are rotatably arranged inside the L base 2 through axle sleeves. The top of the transmission block 34 is movably connected to the support rod 35 through a side plate, and the top of the support rod 35 is movably connected to the bottom of the photovoltaic panel 1 through a movable side frame 36. One side of the screw rod 33 is connected to the output shaft of the transmission motor 31 through a pair of meshing gears 32. The transmission motor 31 is fixed under the L base 2. A slide rail is arranged at a position of the L base 2 near the transmission block 34, and the transmission block 34 slides laterally inside the L base 2.

[0055] In this embodiment, after the transmission motor 31 is started, it can drive the screw rod 33 to rotate inside the L base 2 through the meshing gear group 32. At this time, the transmission block 34 moves laterally inside the L base 2 under the effect of the threaded connection, so as to facilitate the position movement below the support rod 35. At this time, the top of the support rod 35 can pull or push the movable side frame 36, and the movable side frame 36 is fixed between the photovoltaic panel 1, so that the inclination angle between the photovoltaic panel 1 and the ground can be changed;

[0056] This effect can effectively increase the size of the movement space on both sides of the photovoltaic panel 1 during actual operation, especially solving the problem that the traditional cleaning device does not have a good installation space when multiple photovoltaic panels 1 are arranged in an array.

[0057] A self-cleaning method for a photovoltaic power generation device, the specific steps are as follows:

[0058] S1. First, the transmission motor 31 is driven. The transmission motor 31 directly drives the screw 33 inside the L base 2 to rotate through the meshing gear group 32. At this time, the transmission block 34 is restricted by the inner slide rail of the L base 2 to perform horizontal thread transmission, driving the support rod 35 to move downward to one side. At this time, the top of the support rod 35 will pull one side of the photovoltaic panel 1 downward through the movable side frame 36 to tilt, thereby changing the actual orientation angle of the photovoltaic panel 1;

[0059] S2, then by controlling and driving the two sets of active motors 7 at the bottom of the photovoltaic panel 1, the output shaft of the active motor 7 first directly drives the connecting rod 89 to rotate through the friction ring 88, and the top of the connecting rod 89 and the side connecting rod of the cleaning roller 6 move, so that the cleaning roller 6 can be synchronously driven to rotate with the output shaft of the active motor 7 as the axis, so as to drive the cleaning roller 6 to rotate from the bottom of the photovoltaic panel 1 to the top of the photovoltaic panel 1, and the rotation angle is greater than 180 degrees, and then the cleaning roller 6 will fit with the top surface of the photovoltaic panel 1, and the connecting rod 89 can no longer drive the cleaning roller 6 to rotate, and the continuous rotation effect of the active motor 7 will force the friction ring 88 to rotate in the shaft hole below the connecting rod 89, and one end of the active motor 7 and the cleaning roller 6 is fixed with a pulley, and the transmission is transmitted between the pulleys through the transmission belt 81, so that the active motor 7 can normally drive the cleaning roller 6 to rotate around its own axis through the transmission effect of the transmission belt 81 to perform a cleaning operation;

[0060] S3. When the active motor 7 drives the cleaning roller 6 to swing in a circle, the cam 823 fixed on the surface of the active motor 7 is synchronously driven to rotate inside the single-side groove 824 until the protruding position of the cam 823 contacts the concave position of the single-side groove 824. At this time, the rotation effect of the active motor 7 will synchronously drive the main tooth 821 to rotate. The main tooth 821 and the transmission tooth 822 are meshed with each other and limited to rotate between the first placement plate 84 and the second placement plate 85 through the side plate frame 83, and the transmission tooth 822 is meshed with the meshing rail groove 825 on the bottom surface of the photovoltaic panel 1. At this time, the rotation of the transmission tooth 822 will drive the first placement plate 84 and the second placement plate 85 to move horizontally as a whole at the bottom, and synchronously drive the cleaning roller 6 to move and clean on the top surface of the photovoltaic panel 1. The first placement plate 84 and the second placement plate 85 are stabilized by the limiting slide rail 87 with the photovoltaic panel 1, so as to achieve the effect of first alignment and then cleaning.

[0061] S4. During the process of the active motor 7 driving the cleaning roller 6 to move and clean one side of the photovoltaic panel 1 through the second side swing mechanism 8, three groups of water gun heads 5 are installed on the other side of the photovoltaic panel 1 through the mounting frame 44. The two sides of the mounting frame 44 are rotated at the end position of the photovoltaic panel 1 through the axle pins 43. When the micro motor 41 is driven, the shaft on the output shaft of the micro motor 41 engages with the vortex 42, so that the vortex 42 rotates. The vortex 42 is fixed by the axle pin 43, so that the axle pin 43 can drive the mounting frame 44 to swing, thereby driving the three groups of water gun heads 5 to swing from the bottom of the photovoltaic panel 1 to the top of the photovoltaic panel 1 and align with the top surface of the photovoltaic panel 1 for flushing.

[0062] Working principle: When cleaning is required, the transmission motor 31 in the side tilting mechanism 3 is driven first, and its output shaft drives the screw 33 to rotate inside the L base 2 through the meshing gear group 32. At this time, the transmission block 34 moves laterally inside the L base 2 under the effect of the threaded transmission, pulling the bottom of the support rod 35 to move to one side, and the top of the support rod 35 is movably connected to the movable side frame 36. The movable side frame 36 can effectively pull one side of the photovoltaic panel 1 to swing downward, thereby changing the actual tilt angle of the photovoltaic panel 1 and increasing the activity space on both sides of the photovoltaic panel 1. Then the first side swing mechanism 4 and the active motor 7 are started;

[0063] First, the micro motor 41 in the first side swing mechanism 4 is started, and the meshing effect between the vortex rod and the vortex gear 42 on the output shaft drives the vortex gear 42 to rotate. The vortex gear 42 drives the mounting frame 44 to swing on one side of the photovoltaic panel 1 through the shaft pin 43. Three groups of water gun heads 5 are fixed on the mounting frame 44. The water gun heads 5 can be rotated to the upper side of the photovoltaic panel 1 at this time, aligned with the top glass plate of the photovoltaic panel 1, and the flushing operation can be achieved by water supply through the water pipe. On the other hand, the active motor 7 is fixed on the first mounting plate 84. After it is started, the output shaft will first drive the connecting rod through the friction ring 88 89 rotates, and the shaft rod on the top of the connecting rod 89 is movably connected to the side of the cleaning roller 6, so that during the swinging of the connecting rod 89, the cleaning roller 6 will also swing with the output shaft of the active motor 7 as the axis, so that the cleaning roller 6 swings from the bottom of the photovoltaic panel 1 to the top of the photovoltaic panel 1, until it fits with the glass plate on the top of the photovoltaic panel 1. At this time, the connecting rod 89 can no longer drive the cleaning roller 6 to make a circular motion, and the output effect of the output shaft of the active motor 7 will drive the friction ring 88 to slip on the inner side of the shaft hole below the connecting rod 89. At the same time, the cam will be synchronously driven during the rotation of the output shaft of the active motor 7. 823 rotates in the single-sided groove 824 opened on the inner side of the main tooth 821. After the protruding position of the cam 823 contacts the concave position of the single-sided groove 824, the cam 823 can synchronously drive the main tooth 821 to rotate stably between the first placement plate 84 and the second placement plate 85. The stabilizing effect of the main tooth 821 and the transmission tooth 822 is achieved through the side plate frames 83 on both sides. Since the main tooth 821 is meshed with the transmission tooth 822, and the transmission tooth 822 is meshed with the meshing rail groove 825 on the ground of the photovoltaic panel 1, the first placement plate 84 and the second placement plate 85 will be subjected to a lateral meshing. Pulling force is provided, and a limiting slide groove 86 is opened above one side of the first placement plate 84 and the second placement plate 85. The limiting slide groove 86 and the limiting slide rail 87 on the bottom surface of the photovoltaic panel 1 limit sliding, so that the first placement plate 84 and the second placement plate 85 can move laterally as a whole, and the output shaft of the active motor 7 continues to rotate during the movement. At this time, one side of the output shaft of the active motor 7 can also drive the cleaning roller 6 to rotate on the top of the photovoltaic panel 1 through the transmission belt 81, so that the cleaning roller 6 moves laterally on the top of the photovoltaic panel 1 and realizes the self-rotation cleaning operation at the same time, and can realize the storage operation under the photovoltaic panel 1.
