The invention provides manual air acquiring device and method of a rescue capsule. The manual air acquiring device of the rescue capsule is simple in structure, convenient to operate and small in cost. The device comprises an air inlet joint, an air inlet one-way valve, a sealing box, an manual air pump, a multi-parameter air detecting instrument, an air outlet one-way valve and an air outlet joint; the air inlet end of the air inlet one-way valve is communicated with the air inlet joint by threaded connection; the air outlet end of the air inlet one-way valve is communicated with the sealing box through a high pressure clamping sleeve and a stainless steel polishing pipe; the manual air pump is communicated with the sealing box by welding; the air inlet of the air outlet one-way valve is communicated with the sealing box through the high pressure clamping sleeve and the stainless steel polishing pipe, and while the air outlet end of the air outlet one-way valve is communicated with the air outlet joint by screwing; the multi-parameter air detecting instrument is sealed in the sealing box. According to the device and method, the manual air pump pumps air, and then the multi-parameter air detecting instrument in the sealing box detects that components and contents of the air; when the manual air pump presses air, air in the sealing box is exhausted outside, so as to finish the air acquiring and detecting process of the rescue capsule.
Description
technical field [0001] The invention relates to a measuring and testing device and method, in particular to a gas collection and detection device and method. Background technique [0002] The rescue chamber needs to provide more than 96 hours of survival time when people are trapped. According to calculations, the existing rescue chamber gas collection devices (such as rescue chamber electric gas collection devices, CFZ22(A) gas automatic negative pressure samplers, etc.) need 4 This will undoubtedly increase the number of equipment and increase the input cost; in addition, when the existing rescue chamber gas collection device is used, it needs to be fixed in the cabin, the pipeline connection is complicated, and there are many control valves. It makes the operation inconvenient and affects the rescue time; and when the power of the existing gas collection device is exhausted, it needs to be disassembled and replaced with a new negative pressure collection device. The disas...
