Heliostat cleaning device

Abstract

The invention discloses a novel heliostat cleaning device, and relates to the technical field of heliostats. The device comprises a water tank, a frame body, driving devices, a cleaning device and a bottom plate, the water tank is fixedly connected in the frame body, the frame body is fixedly connected on the bottom plate, the number of the driving devices is two, the driving devices are arrangedon two sides of the bottom plate, and the cleaning device is arranged at the front part of the bottom plate; a cleaning trolley can be used for cleaning a heliostat which cannot be cleaned on the inner side, a push plate is used for primarily cleaning sand and dust on the heliostat in the cleaning process, then a sponge column brush is matched with a surrounding baffle plate which can spray waterto carry out more detailed cleaning, then a scraper is used for scraping water, finally the water is further removed through a fluff brush, the heliostat is prevented from being stuck with the dust again due to water pollution, a suction disc is arranged on a track by a driving part, the friction force is increased, the slipping is prevented, the cleaning stability is improved, and a detachable push head and a rubber scraping strip are convenient for later maintenance and replacement.

Description

technical field [0001] The invention relates to the technical field of heliostats, in particular to a heliostat cleaning device. Background technique [0002] Heliostats are a new technology used in the field of photothermal power generation. It usually uses multiple heliostats to reflect light intensively to heat the medium in the heat absorber, generate steam, and drive a steam turbine to drive a generator to generate electricity. Among them, the cleanliness of the mirror surface of the heliostat affects the reflection efficiency, which in turn affects the heating and power generation efficiency. [0003] Tower-type solar power stations are generally built near deserts or Gobi with sufficient sunshine and a vast area. Therefore, dust and some sand particles are often attached to the heliostats. The current cleaning mainly relies on large-scale cleaning vehicles to clean the heliostats by extending the mechanical arm with the cleaning device. Sometimes the heliostats are r...

Problems solved by technology

Therefore, dust and some sand particles are often attached to the heliostats. The current cleaning mainly relies on large-scale cleaning vehicles to clean the heliostats by extending the mechanical arm with the cleaning device. Sometimes the heliostats are relatively concentrated. The length of the robotic arm is limited, and the inner heliostats may not be cleaned. Manual cleaning is required, which makes the cleaning work inconvenient. In addition, after general washing, water stains will be left on the heliostats. Before the water stains are dry , easy to re-attach dust and sand
