Embodiment approach

[0039] According to one embodiment of the present invention, the method for sealing the cable pipeline structure of the present invention includes:

[0040] S1. Connect the base 11 with the cable hole on the side wall A of the ventilation duct of the spacecraft, set the connecting pipe 2 on the body 12, and fasten the connecting pipe 2 with nylon cable ties 3 . In this embodiment, the base 11 is connected to the side wall A by screws, and the annular seal 111 is compressed by the base 11 .

[0041] S2. Tighten the connecting pipe 2 and the cables passing through the connecting pipe 2 with nylon cable ties 3 . In this embodiment, there are at least two nylon cable ties 3 at the fastening position between the connecting pipe 2 and the cable. By fastening the connecting pipe 2 and the cable B, the gap between the connecting pipe 2 and the cable B becomes smaller, thereby further ensuring the tightness of the connecting pipe 2 and the cable B, and enhancing the cable pipeline str...

Abstract

The invention relates to a cable pipeline structure in a spacecraft ventilating duct. The cable pipeline structure comprises a flange (1) and a connecting pipe (2), wherein the flange comprises a base(11) and a main body (12); the connecting pipe (2) is a hose with two layers of high-temperature resistant cloth; the connecting pipe (2) sleeves the main body (12), and the connecting pipe (2) and the main body (12) are fastened through a nylon ribbon. Through holes on the side wall communicate with the flange, and the hose and the flange are fastened through the nylon ribbon, so that the wholecable pipeline structure and the ventilating pipeline are mutually isolated, and the gas leakage in the ventilating pipeline is avoided; therefore, the airtightness of the whole ventilating pipeline is guaranteed.

Description

technical field [0001] The invention relates to a cable pipeline structure and a sealing method, in particular to a cable pipeline structure and a sealing method used in a ventilation duct of a spacecraft. Background technique [0002] The spacecraft mainly controls the temperature and humidity in the cabin by ventilating the personnel and living facilities in the cabin, dissipating heat, and dissipating heat from the equipment. The control effect of temperature and humidity not only directly affects the comfort of the astronauts in the cabin, but also affects The normal work of various instruments and equipment is even related to the safety of astronauts. The orbital height of the manned spacecraft is a microgravity environment. In this case, the natural convection heat transfer effect of the fluid is weakened or disappeared. The existence of this microgravity fluid effect determines that the flow of air in the cabin mainly depends on ventilation. system. The airtightness...
