Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, and in particular to a concentrated photothermal power generation device. Background Art

[0002] Solar thermal power generation is a technology that converts solar thermal energy into electrical energy. Its main forms include trough, tower and dish (pan) systems. Specific application equipment includes solar water heaters and collector towers. Among them, solar water heaters are easily subject to geographical restrictions during installation and use. When installed on the top of a building, additional electricity is required to transport water from a low place to a high place, which easily leads to a waste of resources.

[0003] In order to solve the above problems, the prior art proposes a concentrating solar thermal power generation device with patent publication number CN214120427U. By setting a spherical concentrating mechanism, the utilization rate of light energy can be greatly improved and the loss of light energy can be reduced. At the same time, the spherical concentrating mechanism can greatly increase the width of the light energy receiving surface. At the same time, the optical fiber is used to transmit light energy, which solves the geographical limitation of the equipment. Although it is convenient to reduce the waste of extra electricity through the concentrating mechanism, it is necessary to protect the spherical lens with a transparent protective cover when using it. After long-term outdoor use, dust is easily adhered to the surface of the transparent protective cover. In order to ensure the smooth passage of light, it is necessary to manually clean the dust on the surface of the transparent protective cover regularly. Manual cleaning is prone to be untimely, which will affect the normal contact between the spherical lens and light. Utility Model Content
