Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, specifically to a cleaning robot with an adjustable roller brush angle. Background Technology

[0002] Current cleaning robots typically use a single, fixed angle for their roller brush mechanisms, which is insufficient to achieve ideal cleaning results in the complex surface conditions of photovoltaic panels. If the photovoltaic panel surface is tilted to varying degrees, the fixed-angle roller brush cannot conform to the tilted surface, resulting in ineffective cleaning of certain areas. This leads to dust and dirt residue, reducing the cleanliness of the surface, damaging the brush bristles, increasing device wear and tear, raising maintenance costs, and posing significant safety hazards.

The angle adjustment mechanism includes a sliding member that is adjustable in front and back position and is set on the machine body, and a positioning member that is fixedly installed on the roller brush mechanism. The rear end of the positioning member abuts against the front end of the sliding member to fix the angle of the roller brush mechanism.

[0005] Preferably, the angle adjustment mechanism further includes a fixing component and a threaded adjustment component. The fixing component is fixedly installed on the machine body, and the sliding component is slidably mounted on the fixing component.

[0032] See Figure 1-8 As shown in the figure, as an embodiment of this utility model, a cleaning robot with an adjustable roller brush angle is provided. It includes a machine body 1 and a roller brush mechanism 2 that swings up and down on the machine body 1 to achieve angle adjustment. An angle adjustment mechanism is installed between the machine body 1 and the roller brush mechanism 2. The angle adjustment mechanism includes a sliding member 3 that is adjustable in front and back position on the machine body 1 and a positioning member 4 fixedly installed on the roller brush mechanism 2. The rear end of the positioning member 4 abuts against the front end of the sliding member 3 to fix the angle of the roller brush mechanism 2. That is, by adjusting the front and back position of the sliding member 3, the abutting and supporting position of the positioning member 4 changes, thereby adjusting the up and down angle position of the roller brush mechanism 2. Figure 1 As shown, when the sliding member 3 moves forward, the positioning member 4 swings forward, thereby adjusting the upward swing angle of the roller brush mechanism 2, as follows: Figure 8 As shown, when the sliding member 3 moves forward and backward, the positioning member 4 swings backward, thereby adjusting the downward swing angle of the roller brush mechanism 2. The roller brush mechanism 2 can adjust its angle according to the different tilt angles of the photovoltaic panel, allowing it to conform to the surface of the photovoltaic panel for cleaning. This avoids blind spots that could lead to dust and dirt residue, improving cleaning efficiency and effectively preventing brush bristle damage, reducing device wear and tear, lowering maintenance costs, and eliminating safety hazards. Furthermore, because the angle of the roller brush mechanism 2 is adjustable, the cleaning robot can adapt to roller brush mechanisms 2 with bristles of different hardness and length, resulting in wider adaptability.

[0033] The cleaning robot with adjustable roller brush angle of this invention can be applied not only to the field of solar photovoltaic panels, but also to other cleaning fields, such as glass plate cleaning, etc., without limitation.

[0034] In this embodiment, the angle adjustment mechanism also includes a fixing member 5 and a threaded adjusting member 6. The threaded adjusting member 6 is specifically a bolt. The fixing member 5 is fixedly installed on the machine body 1. The sliding member 3 can be slidably mounted on the fixing member 5. The sliding member 3 has an adjustment screw hole 7 that runs through the front and back. The threaded adjusting member 6 is threadedly connected in the adjustment screw hole 7 and the rear end of the threaded adjusting member 6 abuts against the fixing member 5 for limiting and cooperating so as to realize that the front and back position of the sliding member 3 can be adjusted and mounted on the fixing member 5, making the adjustment operation easier and more convenient.

[0035] In this embodiment, the fixing member 5 includes a horizontal fixing plate 51 and a vertical fixing plate 52 that are L-shaped to each other, and a blocking block 53 fixedly installed at the bottom of the horizontal fixing plate 51. The vertical fixing plate is located above the rear end of the horizontal fixing plate. The vertical fixing plate 52 is detachably fixedly connected to the machine body 1. The rear end of the threaded adjusting member 6 abuts against the blocking block 53 for limiting cooperation.

[0036] In this embodiment, there are multiple blocking blocks 53, which are fixedly installed at the bottom front end of the horizontal fixing plate 51 in the left-right direction, thereby improving the adjustment accuracy of the front and rear position of the sliding member 3.

[0037] In this embodiment, a screw and a nut are also included. The sliding member 3 includes a horizontal sliding plate 31 and a vertical sliding plate 32 that are L-shaped to each other. The vertical sliding plate 32 is located below the front end of the horizontal sliding plate 31. The adjusting screw hole 7 is located inside the vertical sliding plate 32. The horizontal sliding plate 31 has an elongated slot 8, and the horizontal fixed plate 51 has a round hole 9. The screw passes through the elongated slot 8 and the round hole 9 and locks with the nut to fix the horizontal sliding plate 31 on the top of the horizontal fixed plate 51. This setting allows the sliding member 3 to be installed on the fixed plate with adjustable front and rear positions, while improving the connection stability.

[0038] In this embodiment, the positioning member 4 includes a front fixed plate 41 and a rear abutment plate 42 that are L-shaped to each other. The front fixed plate 41 is detachably fixedly installed on the roller brush mechanism 2. The rear end of the rear abutment plate 42 is an arc surface structure 43. The arc surface structure 43 of the rear abutment plate 42 abuts against the front end of the vertical sliding plate 32. That is, the front fixed plate 41 is the fixed end and the rear abutment plate 42 is the swing end. The positioning member 4 can swing freely with the roller brush mechanism 2, so that when the front end of the vertical sliding plate 32 moves forward, it can push the rear abutment plate 42 to swing forward more smoothly, thereby driving the roller brush mechanism 2 to swing upward to achieve angle adjustment. Similarly, when the front end of the vertical sliding plate 32 moves backward, the transmission plate can also swing backward smoothly under the action of gravity, thereby driving the roller brush mechanism 2 to swing downward to achieve angle adjustment.

[0039] In this embodiment, the arc-shaped structure 43 extends in the left and right directions, and the longitudinal section of the arc-shaped structure 43 is a semi-circular surface. This makes the arc-shaped structure 43 of the rear abutment plate 42 and the front end face of the vertical sliding plate 32 close to line contact and abutment, resulting in a smaller contact area, more stable and reliable fit, and prevention of relative sliding.

[0040] In this embodiment, a rotating shaft mechanism 9 is installed between the machine body 1 and the roller brush mechanism 2 to enable the roller brush mechanism 2 to swing up and down on the machine body 1. The rotating shaft mechanism 9 consists of two lug structures that are fixedly installed on the machine body 1 and the roller brush mechanism 2 respectively and connected by a rotating shaft. The angle adjustment mechanism is installed in the middle between the machine body 1 and the roller brush mechanism 2. The rotating shaft mechanism 9 is located on the left and right sides of the angle adjustment mechanism to ensure the stability of the swing connection of the roller brush mechanism 2.

[0041] In summary, the cleaning robot with adjustable roller brush angle of this invention has the following advantages:

[0042] 1. The roller brush mechanism 2 can adjust its angle according to the different tilt angles of the photovoltaic panel, so that the roller brush mechanism 2 can adhere to the surface of the photovoltaic panel for cleaning, making the contact more comprehensive and uniform, avoiding dust and dirt residue in blind spots, improving the cleaning effect, effectively preventing damage to the brush bristles, reducing the wear and tear of the device, lowering maintenance costs, and eliminating safety hazards.

[0043] 2. Since the angle of the roller brush mechanism 2 is adjustable, the cleaning robot can adapt to roller brush mechanisms 2 with bristles of different hardness and length, thus having a wider range of adaptability.

[0044] 3. The front and rear positions of the sliding part 3 can be adjusted simply by adjusting the connection position of the bolts, thereby adjusting the up and down angle of the roller brush mechanism 2. There is no need to disassemble the roller brush mechanism 2. The adjustment process is easy, labor-saving, simple and quick.

[0045] 4. The installation and disassembly of the entire device are extremely simple, requiring no complicated operating steps, saving time and effort and improving efficiency.

[0046] 5. The angle adjustment mechanism is detachably installed between the machine body 1 and the roller brush mechanism 2. If the angle adjustment function fails, it is only necessary to check the angle adjustment mechanism and replace the relevant parts (such as the sliding part, the fixing part 5, and the positioning part 4), which is easy to maintain.
