Description

Technical Field

[0001] The utility model relates to the technical field of heliostat cleaning tools, in particular to a heliostat cleaning device. Background Art

[0002] A heliostat is an optical device that can reflect light from the sun or other celestial bodies in a fixed direction. It is mainly used as an energy collector for tower solar thermal power generation. A heliostat device usually consists of a reflecting plane mirror, a mirror frame, a base and a tracking transmission mechanism. Among them, the reflecting plane mirror is the key component for realizing light reflection, while the mirror frame, base and tracking transmission mechanism ensure that the reflecting plane mirror can accurately and stably track the sun to maintain stable reflection of light.

[0003] Since the heliostat is installed outdoors and there is a lot of dust in the outdoor air, after a period of use, a lot of dust will accumulate on the surface of the heliostat. The accumulation of a lot of dust will affect the reflection effect of the heliostat on light. At this time, in order to ensure sufficient light reflection, it is usually necessary to regularly clean the surface of the heliostat. During the cleaning operation, the traditional operation method is to manually use corresponding tools and water washing, but the manual operation has a large workload and is time-consuming, which affects the cleaning efficiency.

[0004] At present, in order to achieve the effect of efficient cleaning, a mechanized cleaning device is usually selected. This type of cleaning device is generally used in conjunction with a cleaning vehicle. As the vehicle moves forward, the cleaning device is driven to clean during the movement to complete the cleaning operation. However, when this type of cleaning device installed on the vehicle is used, the position of the brush head on the cleaning device is fixed. During the specific operation, the cleaning device is driven to approach the surface of the heliostat for cleaning by the movement of the vehicle. This type of cleaning device strictly requires a constant distance between the vehicle and the heliostat. The distance is not easy to control, and the cleaning device cannot be better attached to the surface of the heliostat for cleaning when the position of the vehicle changes. It is also not convenient to adjust the cleaning device to fit the heliostat for cleaning according to the actual distance between the left and right heliostats, which will affect the cleaning effect on the surface of the heliostat and bring inconvenience to the user. In view of this, we propose a heliostat cleaning device. Utility Model Content
