Concentric fixing device for solar shell and inner container interlayer

Abstract

The invention discloses a concentric fixing device for a solar shell and an inner container interlayer, which comprises an inner container fixing structure, the inner container fixing structure comprises a fixing frame, a sliding sleeve is arranged on the fixing frame, a first sliding rod is inserted into the sliding sleeve, and a second sliding rod is inserted into the sliding sleeve; the lower end of the first sliding rod is connected with a contraction fastener used for fixing the solar inner container. The shell fixing structure comprises a fixing seat connected with the fixing frame, and a clamping structure used for fixing the solar shell is arranged on the fixing seat; the balance adjusting structure comprises a first heat conducting disc and a second heat conducting disc which are sequentially arranged between the solar shell and the inner container interlayer. Through the combined action of the inner container fixing structure, the shell fixing structure and the balance adjusting structure, dynamic balance adjusting and static fixing are combined, concentric fixing of the solar shell and the inner container is achieved, and it is guaranteed that the deformation quantity of the solar shell and the deformation quantity of the inner container are low in the concentric fixing process of the solar shell and the inner container.

Description

technical field [0001] The invention relates to the technical field of a solar shell and an inner liner interlayer, in particular to a concentric fixing device for a solar shell and an inner liner interlayer. Background technique [0002] At present, the fixing of the outer shell and the inner liner interlayer of solar energy products on the market adopts a concentric fixing structure, so that the inner liner interlayer can be heated evenly. A large amount of polyurethane foam is used for filling and fixing. This foam can have the advantages of good thermal insulation effect, low flammability point and low cost. [0003] However, the current industrial filling technology, the polyurethane foam for solar water heaters is formed by one or more pouring and free foaming, and is mainly based on multiple pouring. However, during the foaming process of multiple pouring, the foam at the junction formed by two adjacent pourings is easy to cause foam cracking due to the difference in...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following disadvantages in the prior art. When the existing solar shell and the liner interlayer are assembled and filled with polyurethane foam, a large amount of gas is generated in the foam due to the unevenness of heat and atmospheric pressure. The polyurethane foam will contain a large number of air bubbles. When it cools down, it will shrink, which will cause the interlayer of the inner tank to deviate from the concentric position and make the heat preservation uneven. Therefore, a concentric fixation between the solar shell and the interlayer of the inner tank is proposed. device
