Description

Technical Field

[0001] The utility model relates to the technical field of heliostat installation hangers, and more specifically, to a heliostat installation hanger. Background Art

[0002] In the existing technology, the design of the heliostat installation hanger often has some defects and deficiencies, which may affect the efficiency, safety and stability of the installation of the heliostat.

[0003] First, the structure of existing devices is usually relatively fixed and lacks flexibility, which means that the hoist may not be able to adapt to heliostats of different lengths and sizes. During the installation process, if the hoist cannot be adjusted according to the specific size of the heliostat, it may cause unstable lifting or even failure to properly lift the heliostat. The inflexibility of this fixed structure not only limits the scope of application of the hoist, but may also require additional tools or equipment to assist in installation, increasing the complexity and cost of installation.

[0004] Secondly, the structure of the hoist in the prior art is often relatively simple, and mainly relies on the bottom support to lift the heliostat. This design may cause stability problems during the lifting process. Due to the lack of limit on other directions of the heliostat, the heliostat may tilt or swing during lifting, increasing the risk of falling. This unstable state will not only threaten the safety of the installers, but may also cause damage to the heliostat, affecting the performance and reliability of the solar thermal power generation system.

[0005] In addition, the simple structure of the existing hoist may not be able to effectively limit the tiny movements of the heliostat during the lifting process. Slight shaking or shaking may cause the position of the heliostat to shift, affecting its ability to accurately align with the sun. In a solar thermal power generation system, the precise alignment of the heliostat is crucial to improving the efficiency of heat collection and power generation. Therefore, any instability of the heliostat during the lifting process may have a negative impact on the performance of the entire system. Utility Model Content
