Problems solved by technology

However, for the flat-plate collectors used in the solar thermal power generation industry in domestic and foreign markets, whether it is tube-sheet type or integral channel type, the light-absorbing plate in front of it is made of cloth-grained low-iron tempered glass. When it snows in winter, it is easy to absorb snowflakes, and long-term snowfall will form thick snow on the surface of the collector. The board support frame causes a lot of pressure, which can easily cause deformation of the solar bracket
On the other hand, it blocks the sunlight and reduces the heat collection effect of the collector, resulting in low utilization rate of solar energy, which affects the amount of solar power generation

Embodiment

[0039] like figure 1 and figure 2 As shown, the flexible and adjustable solar thermal panel snow removing, defrosting and dust removal device in this embodiment includes a solar thermal collector bracket 1, a solar thermal collector 2, a retractable bracket 3, a guide rail 4, a flexible metal heat-absorbing curtain 5, a guide Chain 6 , guide chain fixing guide rail 7 and motor 8 . The flexible metal heat-absorbing screen 5 includes a storage box 9 and a flexible metal heat-absorbing screen 10. The storage box 9 is provided with an elastic winding shaft for winding the flexible metal heat-absorbing screen 10. The flexible metal heat-absorbing screen 5 is in a free state. The flexible metal heat-absorbing curtain 10 is wound around the elastic winding shaft and is accommodated in the storage box 9; The thermal curtain 5 exposes the light-receiving surface of the solar thermal collector plate 2 through the contraction of the flexible metal heat-absorbing curtain 10 . The sola...

Abstract

The invention discloses a flexible and adjustable snow and frost removal and dust removal device and method for a solar photo-thermal panel. The device comprises a solar photo-thermal collection panel support, the solar photo-thermal collection panel, a telescopic support, a guide rail, a flexible metal heat absorption curtain and a flexible metal heat absorption curtain driving mechanism. The solar photo-thermal collecting plate is mounted on the solar photo-thermal collecting plate bracket; the telescopic support is installed on the solar photo-thermal collection plate support, the guide rail is arranged on the telescopic support, and the flexible metal heat absorption curtain is placed on the guide rail and located above the solar photo-thermal collection plate. The flexible metal heat absorption curtain driving mechanism is connected with the flexible metal heat absorption curtain, the flexible metal heat absorption curtain driving mechanism can drive the flexible metal heat absorption curtain to move along the guide rail, and the flexible metal heat absorption curtain can unfold and shield the solar photo-thermal collecting plate or contract and expose the light receiving surface of the solar photo-thermal collecting plate when moving along the guide rail. The utilization efficiency of the solar photo-thermal panel is improved to the maximum extent when snowy in winter.

Description

technical field [0001] The invention belongs to the field of solar light and heat, and in particular relates to a device and method for removing snow, defrosting and dusting of a flexible and adjustable solar light heat plate. Background technique [0002] With the proposed carbon neutrality goal, it is imperative to develop new energy sources on a large scale, especially solar power generation. And now the flat plate collectors used in the solar thermal power generation industry in domestic and foreign markets, whether it is a tube plate type or an integral flow channel type, the light-absorbing plate in front of it is a cloth textured low-iron tempered glass. When it snows in winter, it is easy to absorb snowflakes, and long-term snowfall will form thick snow on the surface of the collector. The panel support frame causes a lot of pressure, which is easy to cause deformation of the solar support frame. On the other hand, it blocks the sunlight and reduces the heat collec...
