The specific embodiment

With reference to Fig. 1, hyperbaric oxygen chamber with automatic emergency fire-fighting respiratory function of the present utility model, comprise air compressor machine 1, the air accumulator 2 that links to each other with air compressor machine, cabin body 3, operating console 4, first-level buffer device 5 that is communicated with the cabin body and oxygen source 6, emergent fire plant 7 is set between air accumulator 2 and cabin body 3, at first-level buffer device 5 and oxygen source 6 and 2 of air accumulators emergent breathing equipment 8 is set, wherein emergent fire plant comprises: the water tank 9 of built-in water level limitation device XZ, and the water tank top is provided with the exhaustor 11 by electromagnetic valve DF1 control, the pipeline 12 that is communicated with air accumulator through electromagnetic valve DF2, the water inlet pipe 10 that is communicated with running water pipe through electromagnetic valve DF3, there is outlet pipe 13 the water tank below, and outlet pipe 13 links to each other with the intravital waterfog head 14 in cabin through electromagnetic valve DF4, and photosensitive sensor GG is arranged in the body of cabin; Said emergent breathing equipment be provided in a side of the electromagnetic valve DF5 on oxygen source 6 and 5 pipelines of first-level buffer device and be located at air accumulator 2 and 5 pipelines of first-level buffer device on electromagnetic valve DF6, its circuit connects referring to shown in Figure 2, electromagnetic valve DF1, DF3 links to each other with the normally opened contact J1 ' of relay J 1 respectively, electromagnetic valve DF2, DF4, DF6 links to each other with the normally opened contact J2 ' of relay J 2 respectively, electromagnetic valve DF5 " links to each other; be loaded on and off switch SK1 and water level limitation device XZ switch and relay J 1 coil on the operating console; the normally-closed contact J2 of relay J 2 " constitutes electric loop with the normally-closed contact J2 of relay J 2, photosensitive sensor GG and relay J 2 coils, the normally-closed contact J1 of relay J 1 " constitute electric loop, lock each other by relay J 1 and relay J 2.Even when relay J 2 energising, relay J 1 dead electricity, otherwise J1 energising, J2 dead electricity.Usually, perfectly safe for guaranteeing emergency rating, can be on photosensitive sensor GG hand switch SK2 in parallel, SK2 is installed on the operating console 4, like this, just has induction and the manually dual control dual fail-safe effect of control automatically out of my cabin in the cabin.

The pipeline of the useful ball valve Q1 of cross-over connection, Q2, Q3, Q4, Q5 and Q6 control respectively at the two ends of electromagnetic valve DF1, DF2, DF3, DF4, DF5 and DF6 is in case electromagnetic valve is standby when malfunctioning.

Working condition of the present utility model such as following:

1) the injecting process: open the switch S K1 that is located on the control station, circuit is through water level limitation device XZ, relay J 1 coil, relay J 2 normally-closed contact energized.Relay J 1 coil gets electric, its normally opened contact closure then, and electromagnetic valve DF1, DF3 get electric work, and tap water pipe line is connected, and relies on the tap water pressure Tank Injection Water; Connect gas exhaust piping simultaneously, gas in the water tank of releasing.When water added to designated water level, water level limitation switch XZ disconnected, relay J 1 dead electricity, and electromagnetic valve DF1, DF3 quit work, gas exhaust piping and tap water pipe line blocking-up, water filling is finished.

2) emergent fire plant start-up course: when the photosensitive sensor GG in placing hyperbaric oxygen chamber received the infrared light of burning release, circuit was through relay J 2 coils, relay J 1 normally-closed contact energized.Relay J 2 coils get electric, its normally opened contact closure then, and electromagnetic valve DF2, DF4 get electric work, and the pipeline between air accumulator and water tank is connected, and feed-tank injects gases at high pressure; The pipeline between waterfog head is connected in water tank and the hyperbaric oxygen chamber simultaneously, and under the action of gravity of gases at high pressure and water, waterfog head is realized quick sprinkling fire.Because this locks mutually for relay J 1, J2, thus relay J 2 when electric, relay J 1 dead electricity can guarantee that the gases at high pressure that water tank adds are not released, to reach the purpose of quick extinguishing.

3) emergent breathing equipment start-up course: under normal condition, relay J 2 coils are in off working state, its normally-closed contact closure, electromagnetic valve DF5 work, oxygen supply during with the assurance treatment.When if the condition of a fire takes place, emergent breathing equipment starts, and relay J 2 coils get electric work, then its normally-closed contact disconnect, the normally opened contact closure, electromagnetic valve DF5 dead electricity quits work, the pipeline between oxygen source and the first-level buffer device is blocked, and stops oxygen supply; Electromagnetic valve DF6 gets electric startup simultaneously, and the pipeline between air accumulator and the first-level buffer device is connected, and air enters oxygen uptake pipeline in the cabin by the first-level buffer device, and patient can suck the low oxygen concentration air by face shield, avoids anoxia asphyxia.Can prevent ashes resume combustion in the cabin again because of the input of having blocked oxygen simultaneously.
