[0057] Example 1

[0058] Reference Figures 1 to 4 A schematic diagram of the overall structure of a photovoltaic panel cleaning device is provided, such as... Figure 1 A photovoltaic panel cleaning device includes,

[0059] The main body 100 includes a handle 101 and a head frame 102 located at the end of the handle 101. The handle 101 is easy for the operator to hold, and the head frame 102 provides a position for the installation of the cleaning mechanism 200.

[0060] The cleaning mechanism 200 includes a cleaning brush component 201 mounted on a head frame 102, and a descaling component 202 mounted on the head frame 102 for cleaning the cleaning brush component 201. In daily use, the surface of the photovoltaic panel can be brushed by the cleaning brush component 201. When there is too much dirt on the cleaning brush component 201, the descaling component 202 can clean the cleaning brush component 201.

[0061] The drive mechanism 300 includes a pulling member 301 disposed on the handle 101 and a transmission member 302 disposed between the pulling member 301 and the cleaning brush member 201. The pulling member 301 extends to the operator's gripping position 101c of the handle 101, so that the operator can easily use the pulling member 301 when gripping. The pulling member 301 can drive the transmission member 302, so that the transmission member 302 drives the cleaning brush member 201.

[0062] The cleaning brush component 201 has a cleaning contact surface M. When the pulling component 301 moves in the first direction, the cleaning contact surface M of the cleaning brush component 201 can be driven to turn towards the descaling component 202 through the transmission component 302. When cleaning the photovoltaic panel, the cleaning contact surface M of the cleaning brush component 201 cleans the photovoltaic panel, and the descaling component 202 can clean the cleaning contact surface M of the cleaning brush component 201.

[0063] Specifically, the head frame 102 includes a combination plate 102a and a crossbeam 102b disposed on the combination plate 102a. In this embodiment, there are two combination plates 102a and two crossbeams 102b. The two combination plates 102a and the two crossbeams 102b form a frame structure.

[0064] The cleaning brush component 201 includes a fixed shaft 201a fixed on the assembly plate 102a, a mounting member 201b rotatably mounted on the fixed shaft 201a, a brush body 201c mounted on the mounting member 201b, and a guide member 201d mounted on the mounting member 201b. Fixed shafts 201a are installed on both assembly plates 102a, and mounting members 201b are rotatably sleeved on the outer side of each fixed shaft 201a. In this embodiment, the mounting member 201b is T-shaped, and the brush body 201c is fixed between the two mounting members 201b on the same side. When the mounting member 201b rotates, it can drive the brush body 201c to rotate.

[0065] The composite plate 102a has a guide groove 102a-1 coaxial with the fixed axis 201a. The guide member 201d can move inside the guide groove 102a-1. The guide member 201d can slide inside the guide groove 102a-1. The guide groove 102a-1 is arc-shaped. When the guide member 201d moves inside the guide groove 102a-1, it can drive the mounting member 201b to rotate.

[0066] Furthermore, the transmission component 302 includes a subframe 302a, which is fixed to the assembly plate 102a to provide a mounting position for the transmission component 302.

[0067] The elastic column 302b is mounted on the subframe 302a, and the slider 302c is slidably sleeved on the subframe 302a; the slider 302c can slide on the outside of the elastic column 302b.

[0068] The push limit member 302d is located between the slider member 302c and the guide member 201d; during the sliding of the slider member 302c, it can drive the push limit member 302d to slide.

[0069] Link 302e connects slider 302c and pulling component 301.

[0070] When the pulling component 301 moves in the first direction, it can drive the slider component 302c to move through the connecting rod 302e, drive the push limit component 302d to move through the slider component 302c, and then drive the cleaning brush component 201 through the guide component 201d.

[0071] Furthermore, the guide member 201d includes a guide body 201d-1 slidably disposed inside the guide groove 102a-1, and a force-bearing column 201d-2 fixed on the guide body 201d-1. The guide body 201d-1 is arc-shaped and fits against the inner wall of the guide groove 102a-1, and can move inside the guide groove 102a-1. When the guide body 201d-1 moves inside the guide groove 102a-1, it can drive the mounting member 201b to rotate around the fixed axis 201a. The force-bearing column 201d-2 extends to the inner side of the push groove L.

[0072] The push limiting member 302d has a push groove L, which has a vertical section L1 and a push section L2 connected to the vertical section L1. The vertical section L1 of the push groove L is located below the push section L2. When it is in a clean state, the guide body 201d-1 is located at the bottom end of the vertical section L1.

[0073] In this embodiment, the arc angle of the guide groove 102a-1 is 120 degrees. In the cleaning state, the guide body 201d-1 is located at the bottom end of the vertical section L1. At this time, the cleaning contact surface M can directly contact the surface of the photovoltaic panel. When the guide body 201d-1 moves along the guide groove 102a-1 by an angle of 90 degrees, the cleaning contact surface M can face the descaling component 202. At this time, the guide body 201d-1 can still move along the guide groove 102a-1, so that each position of the cleaning contact surface M can approach and contact the descaling component 202.

[0074] Among them, the lowest position of the guide groove 102a-1 is the initial end N1, and the position with an angle of 90 degrees to the initial end N1 is the approach position N2. The approach position N2 is closest to the descaling component 202. In addition, the end point N3 is a section away from the initial end N1.

[0075] The connection between the pushing section L2 and the vertical section L1 corresponds to the approach position N2. When the guide body 201d-1 reaches the approach position N2, the force-bearing column 201d-2 reaches the connection between the pushing section L2 and the vertical section L1.

[0076] Furthermore, the elastic column 302b includes a column 302b-1 fixed to the subframe 302a, and a first spring 302b-2 sleeved on the outside of the column 302b-1; the slider 302c includes a sleeve block 302c-1 that slides and is sleeved on the outside of the column 302b-1, and a connecting member 302c-2 for connecting the sleeve block 302c-1 and the push limit member 302d.

[0077] When the pulling component 301 moves in the first direction, which is away from the head frame 102, the connecting rod 302e pulls the sleeve block 302c-1, which can drive the sleeve block 302c-1 to move towards the first spring 302b-2 and press the first spring 302b-2. At the same time, the sleeve block 302c-1 drives the push limit member 302d through the connecting component 302c-2, so that the push limit member 302d moves and pushes the force column 201d-2, so that the force column 201d-2 moves from the initial end N1 to the end end N3.

[0078] The vertical segment L1 is perpendicular to the travel direction of the push-limiting member 302d, and the push segment L2 extends obliquely to the rear relative to the travel direction of the push-limiting member 302d. One side of the push segment L2 is the push surface L3. When the force-bearing column 201d-2 separates from the inside of the vertical segment L1, it will contact the push surface L3. During the movement of the push-limiting member 302d, the push surface L3 will push the force-bearing column 201d-2.

[0079] The groove width of the vertical section L1 is matched with the diameter of the force-bearing column 201d-2, while the groove width of the pushing section L2 is greater than the diameter of the force-bearing column 201d-2.

[0080] Operation process: The handle 101 is easy for the operator to hold, and the head frame 102 provides a position for the installation of the cleaning mechanism 200. The surface of the photovoltaic panel can be brushed by the cleaning brush component 201. When there is too much dirt on the cleaning brush component 201, it can be cleaned by the descaling component 202. The pulling component 301 extends to the operator's gripping position 101c of the handle 101, making it convenient for the operator to use the pulling component 301 when holding it. The pulling component 301 can drive the transmission component 302, so that the transmission component 302 drives the cleaning brush component 201. When cleaning the photovoltaic panel, the cleaning contact surface M of the cleaning brush component 201 cleans the photovoltaic panel, and the descaling component 202 can clean the cleaning contact surface M of the cleaning brush component 201.

[0081] Example 2

[0082] Reference Figure 5 The difference between this embodiment and the first embodiment is that the grip 101 is a hollow tubular structure, and the inside is used to install the pulling component 301.

[0083] The pulling component 301 includes a connecting assembly 301a connected to the connecting rod 302e, an extension rod 301b whose end is connected to the connecting assembly 301a and slidably disposed inside the grip 101, and a locking member 301c disposed outside the extension rod 301b. One end of the extension rod 301b extends close to the headrest 102, and the other end extends to the grip position 101c. The locking member 301c is located in the grip position 101c. When in use, the operator can drive the extension rod 301b to move through the locking member 301c. The extension rod 301b can move inside the grip 101 in a first direction and can move in a second direction opposite to the first direction.

[0084] Specifically, the connecting assembly 301a includes a stabilizing block 301a-1, which is located at the end of the extension rod 301b. The stabilizing block 301a-1 has a circular structure and can fit against the inner wall of the grip 101 when it is located inside the grip 101. The connecting block 301a-2 is fixed on the stabilizing block 301a-1 and extends to the outer side of the grip 101. The synchronizing frame 301a-3 is located between the grip 101 and the connecting rod 302e. The grip 101 has a through groove 101a, and the connecting block 301a-2 extends to the outer side of the grip 101 through the through groove 101a.

[0085] When the extension rod 301b slides, it can drive the stabilizing block 301a-1 to slide, thereby driving the connecting block 301a-2 to slide, and then to the synchronous frame 301a-3 to move. In this embodiment, there are two cleaning brush components 201 and two transmission components 302. The two cleaning brush components 201 are located on both sides of the descaling component 202. The synchronous frame 301a-3 is U-shaped, and the two ends are respectively connected to the two transmission components 302.

[0086] When the timing frame 301a-3 connects the two sleeve blocks 302c-1 via the connecting rod 302e, one end of the connecting rod 302e is connected to the sleeve block 302c-1 via a shaft, and the other end of the connection is connected to the end of the timing frame 301a-3 via a shaft. When the extension rod 301b moves in the first direction, the timing frame 301a-3 can pull one end of the connecting rod 302e, causing the end of the connecting rod 302e connected to the sleeve block 302c-1 to move, thereby driving the sleeve block 302c-1 to move, and finally driving the cleaning brush component 201 to rotate by pushing the limiting member 302d.

[0087] Furthermore, the locking member 301c includes an inner block 301c-1 disposed inside the grip member 101 and connected to the extension rod 301b, a limiting block 301c-2 fixed to the inner tube and extending to the outside of the grip member 101, and a gripping member 301c-3 connected to the limiting block 301c-2 and slidably sleeved on the outside of the grip member 101; the grip member 101 is provided with an adjustment groove 101b, the adjustment groove 101b having a sliding section 101b-1 and a locking end 101b-2.

[0088] The through groove 101a is parallel to the sliding direction of the extension rod 301b. When the extension rod 301b slides, the connecting block 301a-2 can move inside the through groove 101a. The adjustment groove 101b is an L-shaped groove, and the end near the head frame 102 is the locking end 101b-2. The locking end 101b-2 has a transverse groove perpendicular to the main groove of the adjustment groove 101b. When the limiting block 301c-2 reaches the inside of the transverse groove, it can prevent the extension rod 301b from sliding, thereby avoiding the problem of the cleaning brush component 201 flipping due to the sliding of the extension rod 301b during the cleaning of the photovoltaic panel, so that the cleaning brush component 201 remains stable when cleaning the photovoltaic panel.

[0089] Furthermore, the sliding section 101b-1 is parallel to the through groove 101a. When the limiting block 301c-2 is inside the sliding section 101b-1, the limiting block 301c-2 can move along the through groove 101a in the first or second direction. Then, the extension rod 301b can be driven to slide in the first or second direction through the built-in block 301c-1. The gripping member 301c-3 is located on the outside of the grip 101, which is convenient for the operator to hold and operate.

[0090] The rest of the structure is the same as in Example 1.

[0091] Operation process: When the extension rod 301b slides, it can drive the stabilizing block 301a-1 to slide, thereby driving the connecting block 301a-2 to slide, and then to the synchronous frame 301a-3 to move. When the extension rod 301b moves in the first direction, the synchronous frame 301a-3 can pull one end of the connecting rod 302e, causing the end of the connecting rod 302e connected to the sleeve block 302c-1 to move, thereby driving the sleeve block 302c-1 to move, and finally driving the cleaning brush component 201 to rotate by pushing the limiting member 302d.

[0092] When the limiting block 301c-2 reaches the inner side of the transverse groove, it can prevent the extension rod 301b from slipping, thereby avoiding the problem of the cleaning brush component 201 flipping over due to the sliding of the extension rod 301b during the cleaning of the photovoltaic panel, so that the cleaning brush component 201 remains stable when cleaning the photovoltaic panel.

[0093] Example 3

[0094] Reference Figure 6 and Figure 7 This embodiment differs from the previous embodiments in that a power compartment 103 is provided between the handle 101 and the head frame 102. The power compartment 103 is used to provide an installation position. The descaling component 202 includes a descaling roller 202a rotatably mounted on the head frame 102, and a rotating column 202b connected to the descaling roller 202a and extending into the inner side of the power compartment 103. The outer side of the descaling roller 202a is provided with flexible protrusions, such as silicone, or bristles, to facilitate cleaning of the brush body 201c. When the rotating column 202b rotates, it can drive the descaling roller 202a to rotate synchronously.

[0095] The inner side of the power compartment 103 is also equipped with a rotating mechanism 400; it includes,

[0096] The first bevel gear 401 is fixedly sleeved on the outside of the rotating column 202b. When it rotates, it can drive the rotating column 202b to rotate synchronously.

[0097] The transmission column 402 is rotatably located inside the power compartment 103;

[0098] The second bevel gear 403 is fixedly sleeved on the outside of the transmission column 402 and meshes with the first bevel gear 401. When the transmission column 402 rotates, it can drive the second bevel gear 403 to rotate, thereby driving the first bevel gear 401 to rotate.

[0099] The transmission gear 404 is located on the outside of the transmission column 402 and can rotate synchronously with the transmission column 402.

[0100] The sliding rack 405 is slidably mounted on the power compartment 103, meshes with the transmission gear 404, and is connected to the connecting block 301a-2. When the extension rod 301b moves in the first direction, it can drive the sliding rack 405 to move in the first direction.

[0101] The sliding rack 405 is also equipped with a connecting strip, which slides and engages with the side wall of the power compartment 103, enabling the sliding rack 405 to remain stable when moving.

[0102] The rest of the structure is the same as in Example 2.

[0103] Operation process: When the extension rod 301b moves in the first direction, it can drive the sliding rack 405 to move in the first direction. At this time, the sliding rack 405 drives the transmission gear 404 to rotate, which drives the transmission column 402 to rotate, thereby driving the second bevel gear 403 to rotate, driving the first bevel gear 401 to rotate, and finally driving the first bevel gear 401 and the rotating column 202b to rotate, so that the descaling drum 202a rotates.

[0104] Therefore, in this embodiment, pulling the extension rod 301b in the first direction not only causes the two brushes 201c to turn towards the descaling roller 202a, allowing the descaling roller 202a to clean the brushes 201c, but also drives the descaling roller 202a to rotate itself, improving the cleaning effect of the descaling roller 202a on the brushes 201c.

[0105] Example 4

[0106] Reference Figure 7 This embodiment differs from the above embodiments in that it also includes an assist mechanism 500, which includes a force ring 501 fixed to the outside of the extension rod 301b; and a second spring 502, one end of which abuts against the force ring 501 and the other end of which abuts against the built-in block 301c-1.

[0107] Among them, the force ring 501 is closer to the head frame 102 than the built-in block 301c-1.

[0108] The rest of the structure is the same as in Example 3.

[0109] Operation process: When the extension rod 301b moves in the second direction, as the limiting block 301c-2 reaches the inner side of the transverse groove, the built-in column will press the second spring 502, causing the second spring 502 to deform. When the limiting block 301c-2 reaches the inner side of the transverse groove, the elastic force of the second spring 502 can press the limiting block 301c-2 tightly against the inner side of the transverse groove, thereby stabilizing the position of the extension rod 301b.

[0110] In addition, when it is necessary to pull the extension rod 301b in the first direction, the limit block 301c-2 rotates and unlocks from the inside of the transverse groove. At this time, the elastic force of the second spring 502 can help the operator pull the extension rod 301b, which saves effort.
