Embodiment Construction

[0016] Further description will be made below in conjunction with the accompanying drawings.

[0017] see figure 1 and figure 2 , the nylon band 3 among the figure fastens the folded solar panel windshield together. The nylon belt fusing mechanism is the resistance wire 4 connected with the heating circuit, and the resistance wire is wound on the nylon belt. After the spacecraft enters the space, when the sailboard needs to be opened, the resistance wire is energized, the nylon belt is blown, and the solar battery sailboard is unfolded under the force of the torsion spring.

[0018] image 3 It is a schematic diagram of the deployment of the solar battery sail. The two legs of the torsion spring 1 are arranged in a straight line and embedded in the small glass fiber reinforced plastic plate 2 of the solar battery sail. The distance between the two solar battery sails is equal to the diameter of the torsion spring 1. Figure 4 for image 3 The A-direction view shows that ...

Abstract

A developing mechanism for the solar cell said board of spaceship is composed of the developable torsional spring, the nylon band for binding the foldable solar cell said board, the fusing unit for cutting off the nylonb and to develop said solar cell said board, and the developed solar cell said board locating mechanism consisting of the automatic extensible locating pin and its locating tube, which are respectively arranged on adjacent solar cell board.

Description

Technical field [0001] The invention belongs to a solar battery sail panel unfolding mechanism in the field of civil spaceflight. Background technique [0002] The solar panel deployment mechanism is very important in the aerospace field. Existing unfolding mechanisms generally belong to rotary joints or hinge mechanisms, and the structure tends to be complex and needs to be driven by a motor. A problem with one of the components will affect the work of the entire mechanism. The space industry has developed to the present. According to statistics, there are about 26 cases of solar panel failures, including about 11 cases of mechanical deployment failures, including Fleet Communications Satellite 5, Alnwick BF1, April Test Communications Satellite, Indian Satellite 1A, and Indian Satellite 1B. , Arab Satellite 1, TV-Sat TV live satellite, Soyuz 1 spacecraft, US weather satellite Nimbus 1, US weather satellite GOES210, TIP navigation satellite, etc. Mechanical failures of th...
