Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic panel cleaning, and in particular to a compact photovoltaic cleaning robot. Background Art

[0002] At present, photovoltaic panel assemblies are a type of power generation device that generates direct current when exposed to sunlight. Since photovoltaic panels are exposed to outdoor environments for a long time, dust and impurities are easily accumulated on the surface of the panels. Dust and impurities will block sunlight and affect the use of photovoltaic panels. Therefore, the surface of photovoltaic panels needs to be cleaned regularly.

[0003] In the related technology, due to the large area of ​​photovoltaic panels, photovoltaic cleaning robots are usually used to clean the surface of photovoltaic panels. The mainstream photovoltaic cleaning robots on the current market are mainly photovoltaic cleaning robots that are engaged at the top and bottom of photovoltaic panels. The photovoltaic cleaning robot only needs to be controlled to move horizontally on the photovoltaic panel once to clean the surface of the photovoltaic panel. In order to ensure the cleaning effect of the photovoltaic panel, a water spray pipe is usually installed on the outside of the cleaning robot to spray water to the photovoltaic panel, so that the photovoltaic panel can be fully cleaned through the cooperation of the brush on the cleaning robot.

[0004] However, if a water spray pipe is directly installed on the outside of the photovoltaic cleaning robot, the exposed water spray pipe will be easily damaged during long-term use. At the same time, the water spray pipe installed on the outside of the cleaning robot will also increase the size of the cleaning robot, making it inconvenient to transport and very inconvenient.

[0005] In view of the above problems, a compact photovoltaic cleaning robot is now designed. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The embodiment of the present application provides a compact photovoltaic cleaning robot, which can solve the problem in the related art of installing a water spray pipe on the outside of the photovoltaic cleaning robot, which not only makes the water spray pipe easily damaged but also increases the size of the cleaning robot.

[0029] See also Figure 1-Figure 6 A compact photovoltaic cleaning robot comprises: a housing 1, a cleaning roller 2, rollers 3, a driving assembly 4 and a water spraying assembly 5, wherein the cleaning roller 2 is rotatably arranged at the lower end of the housing 1, the rollers 3 are provided with a plurality of groups, and the plurality of rollers 3 are rotatably arranged at the lower end of the housing 1, the driving assembly 4 is arranged in the housing 1, and the driving assembly 4 is connected with the cleaning roller 2 and the plurality of rollers 3 to drive the cleaning roller 2 and the plurality of rollers 3 to rotate;

[0030] In this way, when the photovoltaic panel needs to be cleaned, the housing 1 can be placed on the photovoltaic panel, and then the cleaning roller 2 and the plurality of rollers 3 can be driven to rotate by the driving assembly 4, and the housing 1 can be driven to move on the photovoltaic panel by the rotating rollers 3, and at the same time, the photovoltaic panel can be brushed by the rotating cleaning roller 2 to brush off the dust adhering to the photovoltaic panel, thereby automatically cleaning the photovoltaic panel;

[0031] The water spray assembly 5 is provided with two groups, and the two groups of the water spray assembly 5 are symmetrically arranged on both sides of the cleaning roller 2. The water spray assembly 5 includes a water inlet 51, a water inlet channel 52, an inclined surface 53, a plurality of through holes 54 and a plurality of nozzles 55;

[0032] The water inlet channel 52 is provided in the housing 1, and the water inlet channel 52 is located above the cleaning roller 2. The water inlet 51 is provided on the housing 1, and the water inlet 51 is communicated with the water inlet channel 52. The inclined surface 53 is provided at the lower end of the water inlet channel 52, and the inclined surface 53 corresponds to the cleaning roller 2. The plurality of through holes 54 are provided on the inclined surface 53, and the through holes 54 are communicated with the water inlet channel 52. The plurality of nozzles 55 are respectively provided in the plurality of through holes 54.

[0033] In this way, when the photovoltaic panel is cleaned by the device, the water inlet 51 can be connected to the external water supply device, so that the cleaning water enters the water inlet channel 52, and then the water is sprayed out through the nozzle 55 on the through hole 54. Since the inclined surface 53 corresponds to the cleaning roller 2, the nozzle 55 will spray water in the direction of the cleaning roller 2, so that the photovoltaic panel is cleaned through the cooperation of the nozzle 55 and the cleaning roller 2;

[0034] In this way, by opening the water inlet channel 52 in the housing 1, there is no need to install a water spray pipe separately, and the water inlet channel 52 can also be hidden in the housing 1, so that the structure of the device can be made more compact, thereby reducing the volume of the entire device, so as to facilitate subsequent transportation;

[0035] At the same time, the water inlet channel 52 hidden in the housing 1 can also avoid being exposed to the outside and causing damage, thus increasing the service life of the device and making it more practical.

[0036] Specifically, in this embodiment, the inclined surface 53 is thickened;

[0037] In this way, the thickness of the through hole 54 can be increased, so that the strength of the connection between the nozzle 55 and the through hole 54 is higher, thereby enhancing the structural strength of the device and ensuring stability.

[0038] More specifically, the nozzle 55 is threadedly connected to the through hole 54;

[0039] In this way, when in use, the nozzle 55 can be rotated as needed to facilitate disassembly, assembly and replacement of the nozzle 55. In this way, when the nozzle 55 is damaged, it is convenient for the staff to replace the nozzle 55, which is convenient for use.

[0040] Wherein, a plurality of through holes 54 are equidistantly provided on the inclined surface 53;

[0041] The equidistantly distributed through holes 54 can make the nozzles 55 more evenly distributed, so that the multiple nozzles 55 can spray water evenly and fully on the cleaning roller 2, so that the device can clean the photovoltaic panel more fully and has strong practicality.

[0042] Furthermore, in this embodiment, two sets of threading channels 6 are provided on the housing 1, and the two sets of threading channels 6 are symmetrically arranged on both sides of the cleaning roller 2;

[0043] In this way, the wires in the device can be passed through the threading channel 6, so that the circuit of the entire device is hidden in the shell 1. This not only makes the structure of the entire device more compact, but also makes the appearance more simple and beautiful, but also prevents the circuit from being exposed to the outside and damaged, thereby ensuring the service life of the circuit and facilitating use.

[0044] Preferably, the housing 1 is provided with four sets of guide wheels 7, and the guide wheels 7 are rotatably connected to the housing 1;

[0045] In this way, when in use, the guide wheels 7 on both sides of the shell 1 can be respectively clamped on the two sides of the photovoltaic panel, so that the shell 1 can be limited by the four groups of guide wheels 7, so that the shell 1 can only move in a straight line along the edge of the photovoltaic panel, avoiding the shell 1 from being offset during the movement, affecting the cleaning effect of the photovoltaic panel, and having strong practicality.
