Problems solved by technology

[0006] At present, the surface cleaning methods of photovoltaic panels mainly include: manual dry cleaning, that is, manually holding a long-handled mop with a special detergent for cleaning. This method does not have a good cleaning effect and often leaves traces of dust. Photovoltaic panels cause damage; the vehicle carries water and manually controls the washing method. During operation, the impact of water flow on photovoltaic panels is uncontrollable, and it is easy to damage the panel surface. The water stains formed on the surface will block the light and affect power generation, and it also requires a lot of water resources; Although the water washing method of special vehicles or the mechanical cleaning method of special vehicles solves the problem of impact damage to photovoltaic panels by water flow, there are insufficient water consumption and energy consumption of transport vehicles, and vehicles need a certain space for operation, resulting in a large space resource. Waste; the cleaning robot mode is widely used at present, and the cleaning effect has been improved, but there are many moving parts of the equipment, and there are many potential equipment failure points. In addition, the cleaning effect is still not ideal when only the rotating brush type single cleaning mode is used; in addition, Most of the existing cleaning robot facilities use self-provided photovoltaic panels to power the cleaning equipment, and their self-contained photovoltaic panels do not have the conditions for automatic cleaning, which affects power generation efficiency and easily causes unstable operation of equipment due to insufficient power supply

Embodiment 1

[0039] The cleaning device of the present invention can realize group-batch cleaning of user photovoltaic panels, and several photovoltaic panel monomers are arranged in a string (several single photovoltaic panels with a rectangular shape are arranged next to each other on a plane, arranged in a straight line In a group, called a string; often multiple strings of photovoltaic panels are arranged in one area) together, you can clean a single string together, or you can clean multiple strings together (attached figure 1 It is a schematic diagram of the layout of the two strings cleaning together); the cleaning device walks above the surface of the photovoltaic panel, and cleans the dust on the surface of the photovoltaic panel during the walking process.

[0040] In the forward stage of the cleaning device, the front sweeping device 1 of the main blowing system is turned on, the blower starts to blow air, and it is sent to the front sweeping nozzle combination 5 of the front swe...

Embodiment 2

[0041] Embodiment 2: description of the equipment operation sequence of the cleaning device of the present invention

[0042] The working process of the cleaning device is as follows: before the cleaning work starts, the cleaning device is still at one end of the photovoltaic panel string arrangement area, that is, the starting position, waiting to receive the work start command. When the user's photovoltaic panel needs to be cleaned, the automatic control system sends a signal to the cleaning device, the auxiliary sweep control valve 16 on the auxiliary sweep air connection pipe 15 of the auxiliary blow system 3 is opened, and the two control valves of the air supply pipe of the main blow system (The front sweep control valve 8 and the back sweep control valve 12) are closed; the blast system is turned on, and the airflow generated is sent to the auxiliary purge system 3, and the airflow is blown by the auxiliary sweep nozzle combination 13 installed on the auxiliary purge sys...

Embodiment 3

[0047] Embodiment 3: detailed composition and working status description of the equipment of the present invention

[0048] (1) Main purge system

[0049] The main device used to clean the user's photovoltaic panel includes a set of front sweeping device 1 and a set of back sweeping device 2, which are installed on the front and rear of the trolley frame 22 respectively. The front sweeping device is used to purge the dust on the photovoltaic panel during the operation of the cleaning device from the initial position to the end position, and the back sweeping device is used to clean the photovoltaic panel during the operation of the cleaning device from the end position to the initial position. Clean the dust on it. The front sweeping device 1 is composed of the front sweep nozzle combination 5, the front sweep installation pipe 6, the front sweep air connection pipe 7, and the front sweep control valve 8; Between the installation pipes 6, a forward sweep control valve 8 is i...

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of photovoltaic module cleaning, in particular to a photovoltaic panel surface cleaning device. [0003] (2) Background technology [0004] Solar energy is an inexhaustible and inexhaustible renewable resource. Photovoltaic power generation, as a production model of clean energy with great potential, is receiving widespread attention and has become a new energy development direction supported and promoted by the state. In recent years, photovoltaic power generation The construction of power stations is at an all-time high, which has promoted the development of the national economy to a certain extent. [0005] However, it should also be noted that in the practice of photovoltaic power generation production, some deficiencies have gradually been exposed, such as the decline in cleanliness caused by the dust on the surface of photovoltaic panels, which not only leads to a decrease in power generation...
