Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0021] A preferred embodiment of the present invention takes the pyrotechnic product for docking lock in the docking mechanism as an example:

[0022] Strictly control the site before assembling pyrotechnics. The temperature of the assembly site is 15~25°C, and the relative humidity is kept at 20%~60%. , and equipped with an electrostatic wristband; fireworks are strictly prohibited in the venue, and the fire-fighting facilities should be complete and within the validity period.

[0023] Before assembling the pyrotechnic product, process an M3 process grounding threaded hole in the lower part of the docking lock housing; then connect one end of the anti-static process cable to the M3 process grounding threaded hole of the product through the mounting screw M3, and connect the other end to the grounding pile to complete ...

Abstract

The invention relates to a protection method for preventing an initiating explosive device of a docking mechanism from being detonated beforehand. The protection method comprises the following steps: (1) when dowel pin holes are formed for the initiating explosive device and a product after the initiating explosive device is assembled, anti-static grounding process cables are adopted to enable a drilling machine and the product to be synchronously and effectively grounded, and the periphery of the product is wrapped by an anti-explosive blanket; and (2) when the environment test and the performance test are performed for the initiating explosive device and the product, an anti-static grounding process cable is adopted to enable the initiating explosive device to be effectively grounded. The protection method solves such problems as advanced detonation of the initiating explosive device due to improper protection measures and improper operation in such items as formation of the dowel pin holes, the environment test and the performance test for the initiating explosive device and the product after the assembly of the initiating explosive device. The product, obtained through the method, has stable quality, high reliability and proper protection measures.

Description

technical field [0001] The invention relates to a method for preventing pyrotechnics from detonating, in particular to a protection method for preventing premature detonation of pyrotechnics in a space docking mechanism. [0002] Background technique [0003] At present, in the design of the pyrotechnic product of the docking mechanism, it is required that the pyrotechnic product is assembled together with the product during product assembly, that is, the so-called front-loading pyrotechnic product. This is different from the previous launch model and satellite model, which were first assembled with pyrotechnic simulation parts, and then replaced with real pyrotechnic products before launch or before entering the field. [0004] After the pyrotechnic product of the docking mechanism is assembled, the test items such as positioning pin hole, room temperature performance test, vibration test, high and low temperature performance test, etc. need to be carried out together with...
