Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning robot equipment technology, and in particular to a cleaning device for photovoltaic cleaning robots. Background Technology

[0002] Outdoor photovoltaic panels accumulate a lot of dust and sludge over time. This dirt blocks sunlight, reducing the amount of solar radiation received. In particular, moist, acidic or alkaline dust can accelerate the corrosion and aging of the glass cover. Using a photovoltaic cleaning robot can increase the output power by more than 5% and significantly extend the service life. However, existing photovoltaic cleaning robots generally have the problem of inconvenient adjustment of the distance between the cleaning roller and the photovoltaic panel cleaning surface.

[0003] For example, Chinese utility model patent CN206922705U discloses a height-adjustable photovoltaic panel cleaning robot. Although this solution indirectly adjusts the overall height of the cleaning equipment by rotating the handle to drive the fixed swing plate to rotate, thus enabling the cleaning roller to clean photovoltaic panels of different heights, this method of adjusting the height of the cleaning roller requires manual adjustment after the photovoltaic cleaning robot stops, which is very inconvenient in actual use. Furthermore, the cleaning roller may have insufficient structural stability when rotating after the adjustment.

[0004] In view of this, a cleaning device for a photovoltaic cleaning robot is proposed that can solve the above problems. Utility Model Content

[0005] To address the technical challenge of adjusting the height of the cleaning rollers in photovoltaic cleaning robots, this invention provides a cleaning device for photovoltaic cleaning robots.

[0006] This utility model is achieved using the following technical solution: a cleaning device for a photovoltaic cleaning robot, including a slide table, a slot on the slide table, two sliders slidably connected to the inner side of the slot, connecting plates rotatably connected to the lower sides of the two sliders, a cleaning roller shell rotatably connected to the end of the two connecting plates away from the slide table, a cleaning roller rotatably connected between the two sides of the cleaning roller shell, a cleaning roller lifting mechanism for raising or lowering the cleaning roller shell on one side of the slide table, a cleaning roller driving mechanism for rotating the cleaning roller on one side of the cleaning roller shell, and a hanging and mounting mechanism on the other side of the slide table.

[0007] As a further improvement to the above solution, the cleaning roller lifting mechanism includes a bidirectional threaded rod rotatably connected to the slide table. The screw at one end of the bidirectional threaded rod is threadedly connected to the slider on the same side. A second servo motor is installed on the outside of the slide table, and the output end of the second servo motor is fixedly connected to one end of the bidirectional threaded rod.

[0008] As a further improvement to the above solution, the cleaning roller drive mechanism includes a worm gear rotatably connected to one side of the cleaning roller shell. One end of the worm gear passes through the cleaning roller shell and is fixedly connected to one end of the cleaning roller. A worm gear drive mechanism for rotating the worm gear is provided on one side of the cleaning roller shell.

[0009] As a further improvement to the above solution, the worm drive mechanism includes a first servo motor fixedly connected to one side of the cleaning roller shell, and a worm wheel fixedly connected to the output end of the first servo motor, the worm wheel meshing with the worm.

[0010] As a further improvement to the above solution, the hanging and mounting mechanism includes a plurality of suspension rods fixedly connected to one side of the slide table, and each suspension rod has a retainer fixedly connected to the side away from the slide table.

[0011] As a further improvement to the above solution, a high-pressure water pipe is connected to the outside of the cleaning roller shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model is started by a No. 2 servo motor, which drives two sliders to move closer or further apart. Through the interaction of two connecting plates and the cleaning roller shell, the height of the cleaning roller is raised or lowered, thereby realizing the adjustment of the distance between the cleaning roller and the cleaning surface of the photovoltaic panel. It has the advantage of strong structural stability.

[0014] 2. The present invention, through the cooperation of the suspension rod and the clamp, allows the cleaning device to be easily assembled directly onto the frame of the sweeping robot's mobile cart, which has the advantages of being simple to use and easy to maintain.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figures 1-3 A cleaning device for a photovoltaic cleaning robot according to this embodiment includes a slide table 12, on which a slot 11 is provided. In this embodiment, the slot 11 is a T-shaped slot.

[0023] Please combine Figure 1 As shown, two sliders 10 are slidably connected to the inner side of the slot 11, and the sliders 10 are T-shaped block structures;

[0024] Please combine Figure 3 As shown, the lower sides of the two sliders 10 are respectively rotatably connected to the connecting plates 2, and the ends of the two connecting plates 2 away from the slide table 12 are rotatably connected to the cleaning roller shell 1. The cleaning roller shell 1 is a semi-cylindrical structure.

[0025] Please combine Figure 3 As shown, a cleaning roller 14 is rotatably connected between the two sides of the cleaning roller shell 1. A cleaning roller lifting mechanism that raises or lowers the cleaning roller shell 1 is provided on one side of the slide table 12. A cleaning roller driving mechanism that rotates the cleaning roller 14 is provided on one side of the cleaning roller shell 1. A hanging and mounting mechanism is provided on the other side of the slide table 12.

[0026] Please combine Figure 1 As shown, the cleaning roller lifting mechanism includes a bidirectional threaded rod 8 rotatably connected to the slide table 12. The screw at one end of the bidirectional threaded rod 8 is threadedly connected to the slider 10 on the same side. A second servo motor 7 is installed on the outside of the slide table 12. The output end of the second servo motor 7 is fixedly connected to one end of the bidirectional threaded rod 8.

[0027] By rotating the bidirectional threaded rod 8, the two sliders 10 can be moved closer or further apart, thereby enabling the two connecting plates 2 below to open or close together.

[0028] When the two connecting plates 2 are opened, the cleaning roller shell 1 is pulled up, increasing the distance between it and the photovoltaic panel;

[0029] Conversely, when the two connecting plates 2 come close to each other, the cleaning roller shell 1 is pushed downward, reducing the distance between it and the photovoltaic panel;

[0030] Please combine Figure 1As shown, the cleaning roller drive mechanism includes a worm gear 4 rotatably connected to one side of the cleaning roller shell 1. One end of the worm gear 4 passes through the cleaning roller shell 1 and is fixedly connected to one end of the cleaning roller 14. A worm gear drive mechanism for rotating the worm gear 4 is provided on one side of the cleaning roller shell 1.

[0031] Please combine Figure 1 As shown, the worm drive mechanism includes a first servo motor 6 fixedly connected to one side of the cleaning roller shell 1, and a worm wheel 5 fixedly connected to the output end of the first servo motor 6, which meshes with the worm 4.

[0032] Please combine Figure 1 As shown, in this embodiment, the hanging and mounting mechanism includes two suspension rods 9 fixedly connected to one side of the slide table 12, and each suspension rod 9 has a retainer 13 fixedly connected to the side away from the slide table 12.

[0033] Simply hang the card sleeve 13 directly on the photovoltaic mobile trolley workshop;

[0034] Please combine Figure 1 As shown, a high-pressure water pipe 3 is connected to the outside of the cleaning roller shell 1. When it is necessary to spray water during cleaning, a high-pressure water source can be added through the high-pressure water pipe 3.

[0035] The implementation principle of a cleaning device for a photovoltaic cleaning robot in this embodiment is as follows: First, the cleaning device is mounted on the photovoltaic mobile trolley frame by the cooperation of the suspension rod 9 and the clamp 13. When the cleaning roller 14 is far from the surface of the photovoltaic panel and needs to be lowered to contact the surface of the photovoltaic panel, the second servo motor 7 is started to drive the bidirectional threaded rod 8 to rotate, which drives the sliders 10 on both sides to move closer to each other, indirectly driving the two connecting plates 2 to swing and move closer to each other, thereby realizing the function of the cleaning roller shell 1 moving downward. Then, the first servo motor 6 is started to drive the worm gear 5 to rotate, which meshes and drives the worm 4 to rotate, directly driving the cleaning roller 14 to rotate, realizing the function of cleaning the surface of the photovoltaic panel. When water needs to be sprayed, a water source can be connected through the high-pressure water pipe 3.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
