Problems solved by technology

[0006] Among them, manual cleaning is mainly to invest a lot of manpower to clean the heliostats in the mirror field, which is very important for the tens of thousands of heliostats in the mirror field. Said, the workload is high and the cleaning efficiency is very low
[0007] Among them, mechanical cleaning mainly refers to manually driving the cleaning vehicle, washing the mirror surface directly with high-pressure water or washing the mirror surface with a cleaning brush while washing with high-pressure water, which consumes a lot of energy. and high water consumption
[0008] For large-scale mirror fields, the above two cleaning methods have extremely low cleaning efficiency, high time cost, high cleaning water cost, and high energy consumption, which affect the solar energy. The economics of solar thermal power plants

Embodiment 1

[0069] refer to figure 1 As shown, this embodiment provides an automatic cleaning device for heliostats, including a cleaning module and a storage limit module, the storage limit module is set at the end of the heliostat 1, and the heliostat includes a first end and a second end. For the two ends, during the rotation process of the heliostat, the relative position between the first end and the second end in the height direction will change. Among them, the bottom of the heliostat 1 in this embodiment is connected to the top of the heliostat column 10 through the attitude adjustment mechanism, and the tracking of the sun is realized through the attitude adjustment mechanism, and then the height direction between the first end and the second end is realized. change in relative position.

[0070] Specifically, refer to figure 2 As shown, the storage limit module in this embodiment includes a storage cavity 3, the storage cavity 3 is used to store and limit the cleaning module,...

Embodiment 2

[0089] refer to Figure 4 As shown, this embodiment provides an automatic cleaning device for heliostats. The structural difference between the automatic cleaning device for heliostats in this embodiment and the automatic cleaning device for heliostats in Embodiment 1 is that: the automatic cleaning device for heliostats in this embodiment There are two storage limit modules, and the two storage limit modules are respectively arranged at ends on opposite sides of the heliostat 1 . In specific use, the cleaning module can be accommodated in any storage limit module.

[0090] Specifically, when the automatic cleaning device for heliostats in this embodiment is used, firstly, the cleaning module is placed in any storage limit module, and then the cleaning module is passed through after the first expansion and contraction member 5 absorbs water and expands by injecting water. The opening 4 is ejected to the outside of the storage cavity 3, and then the cleaning module slides on t...

Embodiment 3

[0094] refer to Figure 5-Figure 14 As shown, this embodiment provides an automatic cleaning device for heliostats. The structural difference between the automatic cleaning device for heliostats in this embodiment and the automatic cleaning device for heliostats in Embodiment 2 is that: the automatic cleaning device for heliostats in this embodiment The cleaning block 6 is provided with a water storage chamber 13, the top and the bottom of the water storage chamber 13 are provided with a water inlet 14 and a water outlet 15, and the water inlet 14 and the water outlet 15 are all connected with the water storage chamber 13, and the bottom of the cleaning block 6 is provided There is a cleaning pad 7, and the cleaning pad 7 is located directly below the water outlet 15; the cleaning module in this embodiment also includes an opening and closing assembly for controlling the opening and closing of the water inlet 14 and the water outlet 15.

[0095] Specifically, refer to Figure...

Abstract

The invention provides an automatic heliostat cleaning device. The automatic heliostat cleaning device comprises a cleaning module and at least one storage limiting module, and the storage limiting module is arranged at the end of a heliostat; the storage limiting module comprises a storage cavity, the upper side of the storage cavity is provided with an opening allowing the cleaning module to enter and exit from the storage cavity, and a first expansion and contraction piece is installed in the storage cavity; and the cleaning module is stored in the storage cavity of the storage limiting module, the first expansion and contraction piece in the storage limiting module absorbs water to expand and then ejects the cleaning module out of the storage cavity of the storage limiting module, then the cleaning module slides on the mirror face of the heliostat through a posture adjusting mechanism, and finally, the cleaning module slides to the storage limiting module through the posture adjusting mechanism and is stored in the storage cavity of the storage limiting module. According to the automatic heliostat cleaning device, automatic cleaning of the heliostat is achieved, the energy consumption is reduced while the heliostat cleaning effect is guaranteed, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, in particular to an automatic cleaning device for heliostats. Background technique [0002] Solar thermal power generation technology is a clean and stable new energy power generation technology. Its energy storage cost is low, and it can participate in peak regulation and frequency regulation, so it has broad application prospects. At present, solar thermal power generation can be divided into: tower solar thermal power generation, trough solar thermal power generation, and dish solar thermal power generation according to solar energy collection methods; among them, tower solar thermal power generation has high light-to-heat conversion efficiency, high focusing temperature, and control system. Simple installation and debugging, less heat loss and other advantages. [0003] In the field of tower solar thermal power generation, the heliostat is an important part of the towe...
