Description

Technical Field

[0001] The utility model relates to the technical field of cleaning robots, in particular to a brush lifting structure applied to a crawler-type photovoltaic cleaning robot. Background Art

[0002] The photovoltaic cleaning robot is a cleaning robot specifically used in photovoltaic power stations. It aims to increase the power generation and revenue of photovoltaic power stations. It can clean pollutants such as dust, dirt and bird droppings on the surface of photovoltaic panels, improve the power generation efficiency of photovoltaic panels, and reduce the time and cost of manual cleaning.

[0003] The brush structure of the existing crawler-type photovoltaic cleaning robot is fixed. When cleaning, the brush cleaning height is set in advance so that the brush always remains in the same state. When this structure is applied to large-scale rooftop distributed photovoltaic power stations, it is not adaptable to the height difference of the photovoltaic module arrangement gap. When the cleaning robot is walking, the brush will directly squeeze through, affecting the overall stability of the equipment. To this end, we provide a brush lifting structure applied to crawler-type photovoltaic cleaning robots to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-2 As shown, the utility model provides a technical solution: a brush lifting structure applied to a tracked photovoltaic cleaning robot, comprising a first base 1, two second bases 3, a brush frame 7 and an elastic component.

[0024] The first base 1 is mounted on the cleaning robot by bolts, and an electric push rod 2 is hinged on the first base 1. The electric push rod 2 is controlled and powered by the cleaning robot.

[0025] The second base 3 is installed on the cleaning robot by bolts, and the two second bases 3 are each installed with a hinged seat 4, and the two hinged seats 4 are each hinged with a lifting arm 5, and a fixing part 6 is installed on the lifting arm 5. A lifting cross bar 8 is arranged between the two lifting arms 5, and the two ends of the lifting cross bar 8 are respectively fixedly connected to the two lifting arms 5.

[0026] The fixing member 6 can be detachably mounted on the brush frame 7 , and the fixing member 6 can be mounted on the brush frame 7 by bolts.

[0027] One end of the elastic component is installed on the telescopic end of the electric push rod 2, and the other end of the elastic component is hinged on the lifting cross bar 8. The elastic component includes a storage box 9, which is installed on the telescopic end of the electric push rod 2. The storage box 9 is provided with a first through hole 11, and a transmission rod 17 is slidably connected in the first through hole 11. A connecting block 18 is installed at one end of the transmission rod 17, and a connecting ring 10 is fixedly connected to the connecting block 18, and the connecting ring 10 is rotatably connected to the lifting cross bar 8.

[0028] The connection between the telescopic end of the electric push rod 2 and the lifting cross bar 8 can be achieved by using the storage box 9 , the transmission rod 17 , the connecting block 18 and the connecting ring 10 , and the lifting cross bar 8 can rotate on the connecting ring 10 .

[0029] A partition plate 12 is installed in the storage box 9, and the storage box 9 is divided into a guide cavity 14 and a limit cavity 15 by the partition plate 12. A second through hole 13 is opened on the partition plate 12. The end of the transmission rod 17 away from the connecting block 18 passes through the guide cavity 14 and the second through hole 13 in sequence and is fixedly connected to the limit block 16. The limit block 16 is located in the limit cavity 15. The limit block 16 can limit the movement of the transmission rod 17 inside the limit cavity 15.

[0030] A spring 19 is sleeved on the transmission rod 17, and the two ends of the spring 19 are respectively fixedly connected to the connecting block 18 and the storage box 9. The spring 19 is used to elastically support the connecting block 18, so that when the lifting cross bar 8 is subjected to impact force, it can be transmitted to the connecting block 18 through the connecting ring 10, and the spring 19 is used to absorb the impact, thereby realizing adaptive adjustment of the brush skeleton 7.

[0031] A guide groove 21 is provided on the transmission rod 17, and a guide block 20 is slidably connected in the guide groove 21, and one end of the guide block 20 is fixedly connected to the storage box 9, so that when the transmission rod 17 moves, it can slide on the guide block 20 through the guide groove 21, thereby ensuring the stability of the movement of the transmission rod 17 and preventing the transmission rod 17 from rotating.

[0032] Working principle: When the brush skeleton 7 walks on the uneven surface on the cleaning robot, the force generated by the brush skeleton 7 will be transmitted to the lifting cross bar 8 through the lifting arm 5 and the fixing part 6, and the lifting cross bar 8 can be transmitted to the connecting block 18 through the connecting ring 10 when it is subjected to impact, and the spring 19 is used to absorb the impact, thereby realizing the adaptive adjustment of the brush skeleton 7, which not only makes the brush skeleton 7 safer during the cleaning process, but also can adaptively pass through the height difference surface, and will not cause damage to the brush skeleton 7 due to external force, and also reduces the impact force of the lifting structure of the brush skeleton 7, thereby improving the operation stability of the equipment. When the brush skeleton 7 is lifted, the elastic component and the lifting cross bar 8 drive the lifting arm 5 to rotate on the hinge seat 4 through the telescopic end of the electric push rod 2, and then the brush skeleton 7 can be lifted through the fixing part 6.
