Stratospheric airship paved with flexible thin-film solar cells and paving method of flexible thin-film solar cells

Abstract

The invention discloses a stratospheric airship paved with flexible thin-film solar cells and a paving method of the flexible thin-film solar cells. The stratospheric airship comprises an airship body, skirts sewn on the airship body, the flexible thin-film solar cells with Velcro sewn at the edge, Velcro sewn under the edges of the skirts and Velcro sewn above the edges of the flexible thin-film solar cells. The flexible thin-film solar cells are arranged in inner frames formed by the skirts and fixed on the airship body through the Velcro sewn under the edges of the skirts and the Velcro which is sewn above the edges of the flexible thin-film solar cells. According to the paving method, the operation is simple, convenient and time-saving, and the positioning is reliable. The paving method is suitable for paving of flexible element on various curved shapes.

Description

technical field [0001] The invention relates to the field of aerostat application technology and the field of flexible thin film solar cell application technology, in particular to a stratospheric airship equipped with flexible thin film solar cells and a paving method thereof. At the same time, it is also applicable to the application of laying flexible bodies on curved surface shapes for other purposes. Background technique [0002] figure 1 A schematic structural diagram of a stratospheric airship equipped with flexible thin-film solar cells in the prior art is shown. Normally, flexible thin-film solar cells are paved above the stratospheric airship to convert solar energy into electrical energy, which is currently the only production unit available for long-duration stratospheric airships. The reliable paving of flexible thin-film solar cells on stratospheric airships is the key to their successful application in stratospheric airships. [0003] During the lift-off pr...

AI Technical Summary

Problems solved by technology

[0013] 1) Using this method to pave flexible thin-film solar cells can only achieve the limit of the battery on the hull, and it cannot be completely attached to the hull. When the airship encounters airflow during flight, the bottom of the battery will enter the wind, causing The battery shakes, causing battery damage;

[0014] 2) There are many fixing points for binding in this way. If the string is tied too tightly, it will easily cause damage to the battery or hull when the airship expands and deforms; if there is a margin in the binding length, the battery limit is not reliable. can cause battery damage

[0015] 3) This pavement method also has operational disadvantages. If fewer binding points are set, the limit will be unreliable. If more binding points are set, it will take time and effort to bind.

[0019] 1) Adhesive adhesive is easy to age under strong ultraviolet light in the stratosphere, making the adhesive unreliable

[0020] 2) If the adhesive seals the bottom of the battery on the hull, the gas in the confined space will expand during the airship lift-off and cannot be discharged. When the airship rises to an altitude of about 18km, the gas has already expanded About 10 times, the bottom of the battery will bulge, causing damage to the battery; if it is not sealed and glued, air will enter the bottom of the battery when the airship encounters airflow, causing the battery to shake and damage the battery
