A tower-type photothermal power generation reflector mirror cleaning device

Abstract

The invention discloses a mirror surface cleaning device for a tower-type photothermal power generation reflector, which includes an air washing device, a water washing device and a scrubbing device; the air washing device includes an air knife horizontally fixed above the support plate through an air knife bracket, and the air knife is cylindrical , its side wall is provided with an inverted V-shaped blowing port along the axial direction, and its end is connected to the fan through the air pipe; the washing device includes a square tube fixed horizontally above the bracket plate through a square tube bracket, and the side wall of the square tube is arranged with multiple Nozzle, the end of which is connected to the water pump through a water pipe; the scrubbing device includes a motor and a roller brush that is horizontally arranged above the support plate through a roller brush bracket, and the rotating shaft of the roller brush is connected to the output shaft of the inverted motor through a motor reducer; There are mirror fitting parts for adjusting the air wash unit, water wash unit and brush wash unit in place. The invention can make the mirror surface of the reflecting mirror more thorough, greatly reduces the water consumption for washing, greatly reduces the driving requirements for the driver of the cleaning vehicle, and improves the cleaning quality.

Description

technical field [0001] The invention relates to the technical field of mirror cleaning, in particular to a mirror cleaning device for a tower-type photothermal power generation reflector. Background technique [0002] Solar thermal power generation is one of the important projects in the utilization of solar energy. The principle of solar thermal power generation is to gather sunlight to the solar energy collection device through the reflector, use solar energy to heat the heat transfer medium liquid or gas in the collection device, and reheat The water forms steam to drive or directly drive the generator to generate electricity. The dust effect forms a dust covering layer on the surface of the photothermal glass, which significantly reduces the reflection ability of the reflector and greatly reduces the power generation. At present, solar thermal power generation devices have been built in Northwest my country, but the windy and sandy climate makes regular cleaning of sola...

Problems solved by technology

[0003] Globally, especially for tower-type photothermal power plants whose reflectors are plane reflectors, manual cleaning and vehicle-mounted equipment are generally used to clean the reflectors; for manual cleaning, it is only suitable for small-scale photothermal power plants. Power stations, but for the current rapid development of solar thermal power generation, manual cleaning is no longer applicable; while the cleaning efficiency of vehicle-mounted equipment is obviously stronger than that of manual cleaning, but for vehicle-mounted equipment cleaning, manual driving is mostly used, and most of them rely on water washing and brushing. Ways, for example: Zhenjiang Jiangsu Fu Machinery Co., Ltd., whose main business is forklifts, has successfully developed a solar mirror cleaning vehicle for tower flat mirrors through the company's continuous R&D investment, and now some cleaning vehicles have been put into practice In use, the response is good

[0004] There are deficiencies in the above-mentioned mirror cleaning device. At present, the vehicle-mounted cleaning equipment has high requirements for driving operation, and in the case of uneven ground, there are differences in the relative positions between the cleaning device and the mirror surface, but in the cleaning operation It is necessary for the cleaning device to fit the mirror surface better to achieve effective cleaning, and when there is a method of relying on water washing, the amount of water resources that need to be consumed under the operation of cleaning a large number of mirror surfaces is huge
