Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component cleaning, and in particular to a detection device for a photovoltaic cleaning robot and the photovoltaic cleaning robot. Background Art

[0002] Solar panels are the core components of photovoltaic power generation systems. The performance of solar panels directly affects the power generation efficiency of the entire power generation system. The high-efficiency operation of components is of great significance to the entire photovoltaic power generation system. After a long period of operation, dust, bird droppings and other foreign objects will inevitably accumulate on the photovoltaic panels. Foreign objects will cause hot spots on the photovoltaic panels, which will cause damage to the components and reduce the power generation efficiency. In addition, after a long period of operation, the fasteners of some components will become loose, causing the components to shift, which may cause serious safety accidents. Therefore, the cleaning and inspection of photovoltaic panel components are the top priorities of photovoltaic power station operation and maintenance.

[0003] However, the photovoltaic cleaning robots currently on the market can only perform appropriate cleaning operations on photovoltaic panels. Some companies or institutions use drones to inspect components, but the detection clarity is not high. It is difficult to detect small-area foreign objects and slight looseness of fasteners. In addition, many power stations are located in no-fly zones, and manual inspection is used, which takes a long time and is costly. Summary of the invention

[0036] The following will be combined with the embodiments of the utility model and its drawings to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0037] Example 1

[0038] In a specific embodiment 1, Figure 1-Figure 4 As shown, a detection device for a photovoltaic cleaning robot includes an image collector 1, a transition mounting plate 2, a first sealing gasket 3, a fixed cover 4, a second sealing gasket 5, a lens 6, a lamp bead 7 and a shading strip 8.

[0039] The image collector 1 uses a camera with a camera function, which can collect images within the field of view. The image collector 1 and the transition mounting plate 2 are sealed by a first sealing gasket 3. The image collector 1 is fixed to the fixed cover 4 through the transition mounting plate 2. The transition mounting plate 2 and the fixed cover 4 are sealed and fixed by a second sealing gasket 5. The lens 6 is sealed and bonded to the fixed cover 4 with a light-transmissive glass material. While sealing the image collector 1, the image collector 1 field of view can also collect images through the lens 6. The lens 6 divides the fixed cover 4 into an upper cavity 41 and a lower cavity 42. The image collector 1 is fixedly installed in the upper cavity 4 to place external foreign objects. The resolution of the image collected by the image collector 1 is affected. The field of view of the image collector 1 can completely collect the image within the cavity range of the lower cavity 42 through the fixed cover 4. The shading strip 8 is a brush strip composed of plastic wire and installed and fixed on the four sides of the lower cavity 42. It can not only prevent the external light from affecting the image collector 1, but also block certain foreign matter from entering the lower cavity 42, and it will not affect the field of view of the image collector 1. 8 groups of lamp beads 7 are evenly distributed in an array on the image collector 1. The direction of the lamp beads 7 is consistent with the image collection direction of the image collector 1, and at the same time faces the lower cavity 42, which can fill the light inside the lower cavity and improve the resolution of the image.

[0040] Example 2

[0041] In a specific embodiment 2, a photovoltaic cleaning robot includes the detection device in embodiment 1 and a robot body 10.

[0042] This embodiment is an application of Embodiment 1. The robot body 10 referred to in this embodiment can be any robot on the market with moving and cleaning functions.

[0043] In this embodiment, the image collector 1 and the fixed cover 4 are fixedly installed inside the robot body 10. When the robot body 10 is cleaning the photovoltaic module, the robot body 10 carries the image collector 1 to the photovoltaic module at the bottom of the robot body 10 within the range of the motion path, so as to detect the photovoltaic module while cleaning.

[0044] During operation, the robot body 10 performs normal cleaning operations on the photovoltaic panel. During the moving operation, the image collector 1 can simultaneously detect the situation on the panel in real time. The image collector 1 is separated from the photovoltaic panel by a certain distance, and the light is supplemented by the lamp beads 7. The situation on the photovoltaic panel can be clearly photographed, and its coordinate position can be recorded in real time during operation. Through image comparison and screening, the specific location of stains, abnormalities, etc. can be quickly located, which greatly improves the efficiency and accuracy of detection.

[0045] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
