Single-head cleaning brush for water-powered photovoltaic cell panel

Abstract

Single-head cleaning equipment for a water-powered photovoltaic cell panel includes a hydraulic prime motor (micro impact water turbine), a speed-reduction drive device, a disc brush, a working rod, awater inlet pipe, a connection bracket and the like. After flowing through the micro impact water turbine and doing work, clean water flows to the surface of the cell panel again, and the micro impact water turbine drives the disc brush to rotate and clean. An operator holds the working rod by hands to push the cleaning equipment to walk along the surface of the cell panel and then can operate the cleaning equipment, the controllability is good and the efficiency is high. A high-pressure water pump is used for providing a water source (power source), clean water with the working pressure of 4000 KPa is used for driving, and the rotating speed of the disc brush is 700-900 r / min. Water consumption can be adjusted. The cleaning brush can be applied to cleaning of various kinds of photovoltaic power generation equipment, and the cleaning brush is widely used in the growing field of cleaning of distributed type (small-size) photovoltaic power-generation panels.

Description

technical field [0001] The invention relates to a single-head cleaning brush for solar photovoltaic panels, which belongs to a kind of equipment used for cleaning photovoltaic power generation panels; its core hydraulic prime mover is a miniature impact water turbine in the field of hydraulic turbines, which belongs to the field of fluid mechanics and impeller machinery field. Background technique [0002] Photovoltaic power generation panels are installed at an angle in the open air in the form of arrays. Dirt and dust reduce photoelectric conversion efficiency and reduce power generation. Therefore, solar panels need to be cleaned regularly. [0003] The current cleaning methods mainly include manual cleaning, manual tool cleaning, and mechanized cleaning vehicle cleaning; in addition, installation of fixed network pipe spraying on photovoltaic panels, placing crawling cleaning equipment and robots on photovoltaic panels, etc., due to Due to reasons such as cleaning effec...

[0002] Photovoltaic power generation panels are installed in the open air in the form of arrays. Dirt and dust reduce the photoelectric conversion efficiency and reduce power generation. Therefore, solar panels need to be cleaned regularly

[0012] One of the advantages of the above two devices is simple and compact structure, but their disadvantages and shortcomings include: relatively high cost, unsatisfactory service life of the runner

They need to be equipped with high-cost high-pressure water pumps and high-pressure pipelines; they also have high requirements for water quality. The water inlet pipe of the equipment generally requires a professional pre-filter; the runner, the core part, has a relatively harsh working condition, because its blades need to withstand the long-term long-term use of high-pressure water with a pressure exceeding 10 MPa and a flow rate usually exceeding 10 liters / minute. Shock, so the service life of the runner may not be ideal and need to be replaced from time to time
