A space product fire extinguisher structure and its manufacturing method and space product

Abstract

The invention relates to a space product fire extinguisher structure and its manufacturing method and space product. The fire extinguisher structure includes pasting electromagnetic shielding cloth at the through hole of the fire extinguisher, and the electromagnetic shielding cloth is provided with a through hole for piercing the electromagnetic shielding cloth to enter the fire extinguisher. The notch. The invention pastes the electromagnetic shielding cloth on the through hole of the fire extinguisher, which can not only effectively block impurities such as dust and dandruff, but also avoid aging of internal components and further affect the service life of the product. The fire extinguishing cover method can realize electromagnetic sealing, has a good shielding effect on the electric field radiation of 10kHz‑18Ghz, and is completely suitable for the space microgravity environment of complex electronic interference; it can also meet the on-orbit microgravity under the condition of electromagnetic shielding Operating efficiency requirements under the conditions. The fire extinguisher can realize the ergonomic requirements of the emergency operation of rapid puncture with bare hands. Under the condition of space microgravity, the fire spreads quickly, so it needs to be punctured quickly and in time to extinguish the fire, so as to avoid further spread of the fire.

Description

technical field [0001] The invention relates to the related technical field of fire extinguishing of space products, in particular to a fire extinguishing port structure of space products and space products. Background technique [0002] Space products contain a variety of non-metallic materials. At the same time, due to the information requirements of power supply and communication, it is inevitable to use high-power devices, which inevitably leads to fires. Fires occur quickly in the microgravity environment of space. It is necessary to identify fire extinguishers as soon as possible and At the same time, the product contains electronic equipment inside, which needs to be electromagnetically sealed and cannot be designed with openings. [0003] Existing fire extinguishers are generally designed as open fire extinguishers, and most of them use open cover. The open cover is easy to fall into dust, dandruff and other impurities when left for a long time, which will easily lea...

Problems solved by technology

[0002] Space products contain a variety of non-metallic materials. At the same time, due to the information requirements of power supply and communication, it is inevitable to use high-power devices, which inevitably leads to fires. Fires occur quickly in the microgravity environment of space. It is necessary to identify fire extinguishers as soon as possible and At the same time, the product contains electronic equipment, which needs to be electromagnetically sealed and cannot be designed for opening

[0003] Existing fire extinguishers are generally designed as open fire extinguishers, and most of them use open cover. The open cover is easy to fall into dust, dandruff and other impurities when left for a long time, which will easily lead to short circuit or aging of internal components, further affecting the use of the product life

Moreover, the existing technical solutions cannot realize electromagnetic shielding. Due to the complexity of the electronic products inside space products, electromagnetic waves of different frequencies leak out and interfere with other equipment or information transmission channels. seal

In addition, the existing fire extinguishing outlets cannot meet the ergonomic requirements for emergency operation of rapid puncture with bare hands. Under the condition of space microgravity, the fire spreads quickly, so it needs to be pierced quickly to extinguish the fire to avoid further spread of the fire

Therefore, the existing fire extinguishing design cannot meet the requirements of electromagnetic shielding, and also does not meet the ergonomics requirements of microgravity operation
