Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and in particular to a cleaning mechanism and a cleaning device. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. A photovoltaic power generation panel mainly consists of three major parts: a solar panel (module), a controller, and an inverter. The main components are composed of electronic components. Solar cells are connected in series and then encapsulated and protected to form a large-area solar cell module. Together with components such as a power controller, a photovoltaic power generation device is formed.

[0003] After long-term use, a large amount of dust will accumulate on the surface of existing photovoltaic power generation panels. Therefore, it is necessary to clean them. During the cleaning process, relevant cleaning equipment needs to be used. Common equipment for cleaning photovoltaic power generation panels usually has brushes, but the brushes are usually integrally integrated on the cleaning equipment. When the cleaning equipment rubs and cleans against the photovoltaic power generation panel for a long time or when the brushes are accidentally pulled, the brushes are very easy to separate from the cleaning equipment, resulting in a gradual decrease in the number of brushes on the cleaning equipment, and gradually causing the cleaning equipment to malfunction. In this case, the brushes of the cleaning equipment are not replaceable or the replacement steps are cumbersome, increasing the cost of replacing the brushes of the cleaning equipment and reducing the service life of the cleaning equipment, seriously affecting the cleaning efficiency of the photovoltaic power generation panel. Summary of the Invention

[0004] The purpose of the present invention is to provide a cleaning mechanism and a cleaning device that can quickly disassemble the brushes for replacement, reduce the cost of replacing the cleaning equipment, improve the service life of the cleaning equipment, and improve the cleaning efficiency of the photovoltaic power generation panel using the cleaning equipment.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0017] Preferably, the ejecting assembly includes an ejecting disk placed in the housing, a connecting column fixed to the ejecting disk, a limiting disk sleeved on the connecting column and fixed inside the housing, and a spring sleeved on the connecting column. One end of the spring is fixed to the limiting disk, and the other end is connected to the ejecting disk. The driving assembly is drivingly connected to one end of the connecting column passing through the limiting disk, and the driving assembly can release the connection to the connecting column so that the spring drives the ejecting disk to eject out of the housing and apply a force to the pressure plate.

[0018] Preferably, the driving assembly includes a slider fixed to the swivel ring, a compression spring disposed between the slider and the housing, and a connecting rod fixed to the slider. The swivel ring drives the slider and the connecting rod to rotate, and the connecting rod drives the clamping assembly to clamp the pressure plate.

The slider is slidably sleeved on the arc-shaped guide rod, the compression spring is sleeved on the arc-shaped guide rod, and one end of the compression spring is connected to the slider and the other end abuts against or is connected to the inner wall of the groove.

[0020] Preferably, the driving assembly further includes a transmission rod rotatably connected to the housing, a swing rod rotatably connected to one end of the transmission rod, a connecting frame rotatably connected to the end of the swing rod, a fixing rod fixed to the connecting frame, and a support frame fixed to the housing.

[0024] The beneficial effects of the present invention are as follows: After the number of brushes is reduced, by rotating the rotating ring, when the rotating ring rotates to a preset angle, the driving assembly can drive the clamping assembly to release the clamping of the pressure plate and release the restriction on the ejection assembly. The ejection assembly ejects the pressure plate outwards to disengage from the housing, and then the operator can remove the pressure plate and the gasket thereon, replace the gasket, and thus realize the replacement of the brush. Through the above structure, the cost of replacing the cleaning device is reduced, the service life of the cleaning device is improved, and the cleaning efficiency of the photovoltaic panel using the cleaning device is improved.

[0037] Embodiment 1

[0038] This embodiment provides a cleaning mechanism 10, which can quickly disassemble and replace the brush, reducing the cost of replacing the cleaning equipment, increasing the service life of the cleaning equipment, and improving the cleaning efficiency of the photovoltaic power generation panel using the cleaning equipment.

[0039] As Figure 1 shown, the cleaning mechanism 10 includes a housing 1, a pressure plate 2, a gasket 3, a rotating ring 4, a clamping component, a pop-up component, and a driving component. The pressure plate 2 is detachably installed at the bottom of the housing 1. The gasket 3 is installed on the pressure plate 2, and a brush 31 is installed on the gasket 3. The brush 31 is installed in the circumferential direction of the gasket 3 in the form of multiple bristles. The rotating ring 4 is sleeved outside the housing 1 and can rotate relative to the housing 1. The above-mentioned clamping component, pop-up component, and driving component are all arranged inside the housing 1. The driving component is drivingly connected to the clamping component and the pop-up component. After the rotating ring 4 rotates a preset angle in the first direction (clockwise or counterclockwise), the driving component drives the clamping component to clamp the pressure plate 2, and at the same time restricts the pop-up component from applying force to the pressure plate 2. When the rotating ring 4 rotates a preset angle in the second direction (the second direction is opposite to the first direction), the driving component drives the clamping component to release the clamping of the pressure plate 2, and at the same time the driving component can release the restriction on the pop-up component. The pop-up component applies force to the pressure plate 2 to pop the pressure plate 2 out of the housing 1.

[0040] For the above-mentioned cleaning mechanism 10 of this embodiment, after the number of brushes 31 decreases, by rotating the rotating ring 4, when the rotating ring 4 rotates to a preset angle, the driving component can drive the clamping component to release the clamping of the pressure plate 2 and release the restriction on the pop-up component. The pop-up component pops the pressure plate 2 out of the housing 1. Then the operator can remove the pressure plate 2 and the gasket 3 thereon and replace the gasket 3, thus realizing the replacement of the brush 31. Through the above structure, the cost of replacing the cleaning equipment is reduced, the service life of the cleaning equipment is increased, and the cleaning efficiency of the photovoltaic power generation panel using the cleaning equipment is improved.

[0041] In this embodiment, preferably, the cleaning mechanism 10 further includes a chassis 8, which is disposed below the pressure plate 2 and connected to the pressure plate 2. Exemplarily, in this embodiment, a plurality of sleeves 21 penetrating through both ends are provided in the circumferential direction of the pressure plate 2. One end of the sleeve 21 is inserted into the through hole 11 of the housing 1, and a plurality of positioning columns 81 are provided in the circumferential direction of the chassis 8. The positioning columns 81 are inserted into the sleeves 21. By inserting one end of the sleeve 21 into the housing 1 and the positioning column 81 into the sleeve 21, the installation among the chassis 8, the pressure plate 2, and the housing 1 can be realized.

[0042] The above-mentioned gasket 3 is sleeved on the chassis 8 and located between the chassis 8 and the pressure plate 2, and is fixed and limited by the chassis 8 and the pressure plate 2. Optionally, a positioning hole adapted to the positioning column 81 is provided on the gasket 3. When the gasket 3 is sleeved on the chassis 8, the positioning column 81 passes through the positioning hole and is inserted into the sleeve 21. The gasket 3 can maintain good stability on the outer surface of the chassis 8 by means of the positioning column 81, reduce the probability of detachment between the gasket 3 and the chassis 8, and improve the stability between the brush 31 and the housing 1.

[0043] In this embodiment, as Figure 2 shown, a plurality of teeth 22 are provided in the circumferential direction of the surface of the pressure plate 2 facing the chassis 8, and the outer surface of the teeth 22 is in contact with the outer surface of the gasket 3. By the contact between the outer surface of the teeth 22 and the outer surface of the gasket 3, the friction force between the pressure plate 2 and the gasket 3 is increased, thereby preventing the gasket 3 from deflecting, wrinkling, and detaching.

[0044] The above-mentioned rotating ring 4 is rotatably sleeved outside the housing 1 through a bearing, and a plurality of grooves are provided on the outer peripheral wall of the rotating ring 4 so that the outer peripheral wall of the rotating ring 4 forms a structure convenient for an operator to grip.

[0045] In this embodiment, the above-mentioned clamping assembly may include a clamping rod 51. Correspondingly, holes are provided in both the sleeve 21 and the positioning column 81. The driving assembly can drive the clamping rod 51 to pass through the hole in the sleeve 21 and be inserted into the hole in the positioning column 81 to fix the chassis 8 and the pressure plate 2, thereby realizing good fixation of the gasket 3.

[0046] As Figure 3As shown, the above-mentioned pop-up component includes a pop-up disk 61, a connecting column 62, a limiting disk 63 and a spring 64. The pop-up disk 61 is arranged inside the housing 1. When the pop-up disk 61 is not popped up, its end face is flush with the lower end face of the housing 1, thus not affecting the installation of the pressure plate 2. The above-mentioned connecting column 62 is fixed on the pop-up disk 61. The above-mentioned limiting disk 63 is sleeved on the connecting column 62 and is fixed inside the housing 1. One end of the above-mentioned spring 64 is fixedly connected to the limiting disk 63, and the other end is connected to the pop-up disk 61. The above-mentioned driving component is driven and connected to one end of the connecting column 62 passing through the limiting disk 63, that is to say, the driving component can be connected to the connecting column 62. At this time, the whole pop-up component is in a non-pop-up state, and the end face of the pop-up disk 61 is flush with the lower end face of the housing 1. When the driving component drives the clamping rod 51 to disengage from the sleeve 21 and the hole on the positioning column 81 and the driving component releases the connection to the connecting column 62, the pop-up disk 61 will pop up under the action of the spring 64 and apply a force to the pressure plate 2, so that the sleeve 21 of the pressure plate 2 disengages from the housing 1, realizing the separation of the pressure plate 2 and the housing 1. The setting of this structure makes the disassembly of the pressure plate 2 more convenient and fast.

[0047] Preferably, multiple groups of the above-mentioned pop-up components are provided, and the multiple groups of pop-up components are circumferentially and evenly distributed inside the housing 1. Correspondingly, the above-mentioned driving component and the clamping component are also provided in multiple groups. In this embodiment, Figure 4 as shown, 4 groups of pop-up components are provided.

[0048] In this embodiment, the above-mentioned driving component adopts the following structure to drive the clamping rod 51 to fix the housing 1, the pressure plate 2 and the chassis 8. As Figure 5 shown, the driving component includes a slider 71, a compression spring 72 and a connecting rod 73. The slider 71 is fixedly connected to the rotating ring 4 and can rotate with the rotation of the rotating ring 4. The compression spring 72 is arranged between the slider 71 and the housing 1 and can reset the slider 71 after the slider 71 rotates with the rotating ring 4 to a preset angle and loses external force. The above-mentioned connecting rod 73 is fixedly connected to the slider 71 and rotates with the rotation of the slider 71. The above-mentioned clamping rod 51 is fixed on one side of the connecting rod 73 and faces the holes on the sleeve 21 and the positioning column 81. When the rotating ring 4 is rotated, the rotating ring 4 drives the slider 71 and the connecting rod 73 to rotate, and the connecting rod 73 can drive the clamping rod 51 to insert into or disengage from the holes on the sleeve 21 and the positioning column 81.

[0049] Preferably, in this embodiment, a groove 12 is provided inside the housing 1, and an arc-shaped guide rod 13 is provided in the groove 12. The arc of the arc-shaped guide rod 13 is consistent with the arc of the rotating ring 4, and the above-mentioned slider 71 slides on the arc-shaped guide rod 13. Through the arc-shaped guide rod 13, the sliding trajectory of the slider 71 can be determined, so as to ensure that the clamping rod 51 driven by the slider 71 and the connecting rod 73 can be accurately inserted into the holes on the sleeve 21 and the positioning column 81, and smoothly separated from the holes in the sleeve 21 and the positioning column 81.

[0050] In this embodiment, the driving assembly further includes the following structure to realize the driving of the ejection assembly. As Figure 3 and Figure 5 shown, the driving assembly further includes a transmission rod 74, a swing rod 75, a connecting frame 76, a retaining disc 77, a fixing rod 78 and a support frame 79. The transmission rod 74 is rotatably connected to the housing 1. A roller 70 is provided at one end of the connecting rod 73, and the roller 70 can contact the transmission rod 74 and drive the transmission rod 74 to rotate. The above-mentioned swing rod 75 is rotatably connected to one end of the transmission rod 74, and the connecting frame 76 is rotatably connected to the end of the swing rod 75 that is not connected to the transmission rod 74. The above-mentioned retaining disc 77 is fixedly connected to the connecting frame 76, and the fixing rod 78 is fixedly connected to the retaining disc 77, and one end of the fixing rod 78 can be inserted into the part where the connecting column 62 passes through the limiting disc 63 (specifically, a hole is opened in the part where the connecting column 62 passes through the limiting disc 63, and the fixing rod 78 passes through this hole to limit the connecting column 62). The above-mentioned support frame 79 is fixedly connected to the inside of the housing 1, and the fixing rod 78 can slide through the support frame 79. When the connecting rod 73 rotates with the slider 71, the roller 70 on the connecting rod 73 will roll on the side wall of the transmission rod 74. At this time, the transmission rod 74 will be driven by the roller 70 to rotate, causing the swing rod 75 at one end of the transmission rod 74 to swing. During the swinging process of the swing rod 75, it drives the connecting frame 76 and the fixing rod 78 to move. The fixing rod 78 slides relative to the support frame 79 and disengages from the hole of the connecting column 62, and the driving assembly releases the restriction on the ejection assembly. At this time, the ejection assembly can eject the pressure plate 2. Conversely, when the fixing rod 78 slides relative to the support frame 79 and inserts into the hole of the connecting column 62, the ejection assembly is restricted and cannot apply force to the pressure plate 2.

[0051] Preferably, the above-mentioned transmission rod 74 is divided into two parts with its rotation axis as the boundary. One part is the first transmission part, and the other part is the second transmission part. The roller 70 rolls on the side wall of the first transmission part, and the swing rod 75 is rotatably connected to one end of the second transmission part. The above-mentioned first transmission part has an arc-shaped structure, and the distance between this arc-shaped structure and the rotating ring 4 gradually decreases along the direction away from the rotation axis of the transmission rod 74. When the roller 70 rolls along the first transmission part, the transmission rod 74 can be rotated.

[0052] In this embodiment, preferably, reference can be made to Figure 1 andFigure 5 , a water tank 82 extends from the chassis 8 towards the pressure plate 2. The water tank 82 passes through the pressure plate 2 and is hermetically abutted against the outer shell 1. The outer shell 1 is provided with a water inlet 14 communicating with the water tank 82, and a plurality of water outlet holes 821 are provided at the bottom of the water tank 82. Through the setting of this structure, when the cleaning mechanism 10 cleans the photovoltaic panel or other products, it can clean while brushing with the brush 31 and while spraying water, making the cleaning effect of the cleaning mechanism 10 better. In this embodiment, the water inlet 14 of the outer shell 1 can be connected to a water storage bottle to realize the transportation of water.

[0053] When the brush 31 of the cleaning mechanism 10 in this embodiment needs to be replaced, first rotate the rotating ring 4. During the rotation of the rotating ring 4, the slider 71 is driven to slide along the arc-shaped guide rod 13. At this time, the compression spring 72 contracts under the influence of the sliding force of the slider 71. During the sliding of the slider 71, the connecting rod 73 is used to drive the clamping rod 51 to move. The clamping rod 51 slides in the holes of the positioning column 81 and the sleeve 21, and the clamping rod 51 gradually disengages from the holes of the positioning column 81 and the sleeve 21 until the rotating ring 4 rotates a preset angle and cannot continue to rotate, and the position of the rotating ring 4 is kept stationary.

[0054] At the same time, during the rotation of the rotating ring 4, the connecting rod 73 drives the roller 70 to roll on the outer surface of the transmission rod 74, and the transmission rod 74 is driven to rotate inside the outer shell 1. During the rotation of the transmission rod 74, one end drives the swing rod 75 to swing. During the swing of the swing rod 75, the other end swings on the connecting frame 76 and simultaneously pulls the connecting frame 76 to move. At this time, the stop plate 77 drives the fixed rod 78 to slide on the support frame 79 following the movement of the connecting frame 76, and the fixed rod 78 gradually moves out of the hole of the connecting column 62 until the rotating ring 4 stops rotating and the fixed rod 78 is completely disengaged from the hole of the connecting column 62. The spring 64 is in a compressed state when the pressure plate 2 is fixed to the outer shell 1. When the fixed rod 78 is completely disengaged from the hole of the connecting column 62, the spring 64 drives the connecting column 62 to disengage from the limit disc 63 and pop outwards. The pop-up disc 61 then gradually pushes the pressure plate 2 to move under the action of the spring 64, and the pressure plate 2 gradually separates from the outer shell 1. Subsequently, the disassembly of the pressure plate 2 and the outer shell 1 can be realized. Then, the pressure plate 2 is removed from the chassis 8, the teeth 22 on the pressure plate 2 are separated from the gasket 3, the gasket 3 with severely worn brushes 31 is removed from the outer surface of the chassis 8, and a new gasket 3 with complete brushes 31 is replaced on the chassis 8.

[0055] The above-mentioned cleaning mechanism 10 of this embodiment can realize the quick disassembly and replacement of the brush 31, reducing the cost of replacing the cleaning equipment.

[0056] It should be noted that the above-mentioned cleaning mechanism 10 of this embodiment can clean the photovoltaic panel or other products.

[0057] Embodiment 2

[0058] This embodiment provides a cleaning device, such as Figure 6 shown. The cleaning device includes the cleaning mechanism 10, a grip 20, a bracket 30, and a motor 40 described in Embodiment 1. The bracket 30 is fixed to one end of the grip 20, the motor 40 is installed on the bracket 30, and the output end of the motor 40 is fixedly connected to the housing 1 of the cleaning mechanism 10. The entire cleaning mechanism 10 is driven to rotate by the motor 40, thereby realizing the rotation of the brush 31. During the rotation of the brush 31, the photovoltaic panel or other products are cleaned.

[0059] It can be understood that during the rotation and cleaning process of the brush 31, water is sprayed onto the photovoltaic panel or other products through the water outlet holes 821 on the chassis 8, which can further enhance the cleaning effect of the cleaning mechanism 10.

[0060] Preferably, two cleaning mechanisms 10 are provided in this embodiment, and two motors 40 are provided and symmetrically installed on the bracket 30. With two cleaning mechanisms 10, the cleaning effect is better. Of course, it can be understood that the number of cleaning mechanisms 10 in this embodiment is not limited, and it can also be three or more, depending on the specific usage requirements.

[0061] The cleaning device of this embodiment reduces the cost of replacing the cleaning device, improves the service life of the cleaning device, and improves the cleaning efficiency of the photovoltaic panel using the cleaning device through the above cleaning mechanism 10.
