Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic panel cleaning devices, and in particular to a novel cleaning device suitable for photovoltaic panels. Background Art
[0002] With the large-scale installation and application of photovoltaic panels, the maintenance of existing photovoltaic panels has become an important operational issue. Dust that falls on the surface of photovoltaic panels will block sunlight, reduce the transmittance of the photovoltaic module surface glass, and reduce the amount of solar radiation received; on the other hand, it will cause the heat transfer form of the photovoltaic panel surface to change. The dust absorbs solar radiation and converts it into its own heat energy, while blocking the heat dissipation of the photovoltaic module cover glass.
[0003] At present, long roller brushes are basically used to clean photovoltaic panels. Long roller brush cleaning equipment without outer covers adopts the brush + water cleaning method, and long roller brushes with outer covers basically adopt the waterless dry brush cleaning method. The problems with the above two long roller brush cleaning structures are: during the cleaning process, the contact time between the bristles and the panel is short. If a waterless cleaning method is used, the bristles on the roller brush will find it difficult to brush away fine dust, and the cleaning effect is poor. If a water cleaning method is used, water resources are scarce in many places, and high water quality requirements are required. At the same time, the use of water cleaning may also cause corrosion and short circuit problems to photovoltaic equipment. Utility Model Content
[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide a new cleaning device suitable for photovoltaic panels. By integrating cleaning function components, the cleaned dust is vacuumed to achieve the purpose of effectively cleaning the fine dust on the photovoltaic panels, solving the secondary pollution caused by the dry sweeping method, and facilitating the switching between the dry sweeping and water washing methods.
[0005] The technical solution of the utility model is as follows:
[0006] A new cleaning device suitable for photovoltaic panels includes a dust collecting shell and a roller brush, and is characterized in that: a driving motor is arranged on one side of the dust collecting shell; the roller brush is installed in the dust collecting shell in an axial connection manner, and the power output end of the driving motor is connected to the roller brush; a plurality of suction ports are arranged on the dust collecting shell, and each of the suction ports is provided with a dust collecting pipe, and each dust collecting pipe is collectively connected to the dust collecting port.
[0007] Preferably, a pressure sensor is provided at the middle position of the dust collecting housing. The pressure sensor is externally connected to a mechanical arm of a cleaning platform such as a cleaning robot, and the pressure sensor detects and feeds back the pressure exerted by the entire cleaning device in contact with the photovoltaic panel.
[0008] Preferably, an ultrasonic ranging probe is provided on the edge of the dust collecting shell.
[0009] Preferably, three ultrasonic ranging probes are arranged at equal intervals below the front and rear sides of the dust collecting housing to measure the distance between the cleaning operation part and the photovoltaic panel.
[0010] Preferably, the edge of the dust collecting housing is also provided with a dust detection sensor. Two dust sensors are provided on the front and rear edges of the dust collecting housing.
[0011] Preferably, the front and rear edges of the dust collecting housing are also provided with a plurality of nozzles, and the nozzles are respectively connected with water distribution pipes. The water distribution pipes can be externally connected to the water supply tank assembly of the cleaning platform.
[0012] Preferably, one end of the roller brush is connected to one side of the dust collecting housing through a seat bearing, and the other end is connected to the power output end of the driving motor by a flat key connection; the lower part of the roller brush is exposed from the dust collecting housing.
[0013] The dust collection port can be externally connected to a fan assembly of the cleaning platform.
[0014] Beneficial effects of the utility model
[0015] The utility model has a reasonable and novel design and is convenient and effective to use. The dust on the photovoltaic panel can be vacuumed by integrating the vacuum and cleaning components, effectively cleaning the fine dust on the photovoltaic panel and solving the secondary pollution caused by the dry sweeping method. At the same time, the setting of the nozzle and the water supply component facilitates the switching between the dry sweeping and the water washing methods, thus improving the adaptability of the cleaning device.
[0016] The pressure sensor is mainly used to monitor the contact surface pressure between the cleaning equipment and the photovoltaic panel in real time during the cleaning operation after the cleaning equipment is docked and fixed. It is especially convenient for unmanned platform autonomous operation and remote operation, and timely operation to adjust the distance to avoid excessive contact pressure between the cleaning equipment and the photovoltaic panel, which may cause damage to the photovoltaic panel.
