Embodiment Construction

[0021] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Accompanying drawing is the frock structure diagram of the glue filling method of aircraft nickel-hydrogen storage battery of the present invention, as shown in the embodiment of accompanying drawing, method of the present invention comprises the steps:

[0023] Step 1, assemble before glue filling;

[0024] As shown in the figure, put the nickel-hydrogen battery cell 1 into the sleeve 3, put the glue sealing ring 2 on the upper edge of the sleeve 3; then put the sleeve 3 into the glue sealing tool 4, and pass the assembly form a whole.

[0025] The above-mentioned nickel-hydrogen battery cell 1 is a cylinder with hemispheres at both ends, and the sleeve 3 is a thin-walled aluminum alloy cylinder with a ring at the bottom; role, but also play the role of sealing the upper part of the cuff. The glue filling and sealing tool 4 is a set of combi...

Abstract

The invention relates to an electric source of a space air vehicle, and discloses a glue potting method of a hydrogen-nickel storage battery of the air vehicle, which comprises the steps of: 1. assembling before potting the glue; 2. potting the glue; 3. vacuumizing; and 4. solidifying under normal temperature and normal pressure. The method solves the problem for filling glue into a narrow gap between the hydrogen-nickel storage battery and a sleeve, and has the benefit effects of simple structure, convenient assembly, low cost, even and compact glue filling and good consistency, etc.

Description

technical field [0001] The invention relates to a manufacturing method of a space vehicle power supply, in particular to a glue filling method for a hydrogen-nickel battery used in a space vehicle. Background technique [0002] As an energy storage power supply, the nickel-hydrogen battery is an important part of the satellite's primary power supply subsystem. It will undertake the task of supplying power to the entire satellite during the active flight after the satellite is switched from the internal power supply and during the earth shadow period. The only source of energy is the core factor that determines the on-orbit working life of the primary power supply. Therefore, the energy storage power supply must be highly reliable in order to meet the power supply requirements during the entire satellite launch and on-orbit operation. [0003] In the nickel-hydrogen battery pack, the fixing of the single battery is to adopt the method of cementing with the sleeve, that is, a...
