Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment for photovoltaic power stations, and in particular to an automatic cleaning system and a floating photovoltaic power station. Background Art

[0002] Currently, floating photovoltaics only account for 2% of the total global photovoltaic demand, but it is expected to reach a compound annual growth rate of 15% in the next decade, and the global cumulative installed capacity is expected to exceed 58GW. Floating photovoltaics are installed in reservoirs, lakes, rivers and offshore areas. A notable feature of these areas is the large number of water birds, which often inhabit photovoltaic modules. This will leave their excrement on the photovoltaic modules, resulting in reduced power generation in the power station and module failure due to the formation of hot spots on the modules.

[0003] At the same time, the operation and maintenance of floating power stations is more difficult than that of ground power stations, especially for offshore marine photovoltaic power stations, which are far away from the shore and have high single operation and maintenance costs. Therefore, there is a strong prospect and necessity for deploying unmanned cleaning systems on the water surface.

[0004] At present, the conventional method for automatic cleaning of ground photovoltaic power stations is to use a dry-hanging robot. The robot moves along the frame of the photovoltaic module and removes stains on the surface of the module with a brush. It is difficult to remove sticky stains such as bird droppings. Dry-hanging robots are usually unattended and fully automatic, and the cleaning frequency can be as low as once a day.

[0005] Another way to clean is to use a crawler robot, which is connected to an external water pipe and cleans under human supervision. This method has a lower cleaning evaluation, and the cleaning interval is usually more than one month.

[0006] The above two cleaning methods have the following defects:

[0007] As for the dry-hanging cleaning robot, it is not suitable for floating power stations on the water surface, and the dry-hanging cleaning effect on stains such as bird droppings is poor.

[0008] Conventional crawler cleaning robots are all manned, with a low cleaning frequency, and water cleaning usually requires an external water pipe supply. Utility Model Content

DETAILED DESCRIPTION

[0043] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0044] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration."

[0045] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0046] To facilitate understanding of the automatic cleaning system and floating photovoltaic power station provided in the embodiment of the present application, its application scenario is first explained. The automatic cleaning system and floating photovoltaic power station provided in the embodiment of the present application are used to realize a fully automatic unattended cleaning method, which greatly reduces the frequency of cleaning, reduces the operation and maintenance costs while increasing the power generation of the power station, and is applied to photovoltaic power stations. At present, for the automated cleaning of ground photovoltaic power stations, the conventional method used is a dry-hanging robot. The robot moves along the frame of the photovoltaic module, and removes stains on the surface of the module by a brush during cleaning. It is difficult to remove sticky stains such as bird droppings. The dry-hanging robot is usually an unattended fully automatic mode, and the cleaning frequency can be once a day. Another cleaning method is to use a crawler robot, which is cleaned by an external water pipe and in a manned manner. This method has a low cleaning evaluation, and the cleaning interval is usually more than one month. The above two cleaning methods have the following defects: For the dry-hanging cleaning robot, it is not suitable for floating power stations on the water surface, and the dry-hanging type has a poor cleaning effect on stains such as bird droppings. Conventional crawler cleaning robots are all manned, with low cleaning frequency, and water cleaning usually requires external water pipes. For this reason, the present application embodiment provides an automatic cleaning system to achieve a fully automatic unmanned cleaning method, which greatly reduces the frequency of cleaning, increases the power generation of the power station, and reduces the operation and maintenance costs. The following is a detailed description of the embodiment in conjunction with specific drawings.

[0047] refer to Figures 1 to 3 , Figure 1 A schematic diagram of the structure of the automatic cleaning system provided in an embodiment of the present application. Figure 2 A schematic diagram of the structure of the cleaning module provided in an embodiment of the present application. Figure 3 This is an electrical block diagram of the automatic cleaning system provided in the embodiment of the present application. Figure 1 In the embodiment of the present application, an automatic cleaning system is provided, including: a control module, a cleaning module and a water treatment module 1. The cleaning module is electrically connected to the control module. The water treatment module 1 is electrically connected to the control module. The cleaning module and the water treatment module 1 are connected through a pipeline.

The specific structure of the control module and the control program fixed therein are not shown in the figure, which can be realized by conventional technology and equipment and will not be described here.

[0049] In the above technical solution, by setting up a control module, a cleaning module and a water treatment module 1, a self-contained water supply device is realized, and a fully automatic unattended cleaning method is realized, which greatly reduces the frequency of cleaning, thereby increasing the power generation of the power station and reducing the operation and maintenance costs.
