Fig. 2 is a schematic structural diagram of the emergency air supply device of the diving suit.
As shown in fig. 2, the emergency gas supply device for diving suit comprises: the gas cylinder comprises a gas cylinder 1, a gas cylinder valve 2, a pressure reducer 3, a three-way joint 4, a gas supply switch 5, a gas supply pipe 6 and a gas supply joint 8.
In the embodiment, the working pressure of the gas cylinder 1 is 20MPa, the volume of the gas cylinder is 1.3L, the gas supply flow is 200-300L/min, and the use depth is 150m or less. In the use depth range, the safe breathing time of the gas in the diving suit hood can be prolonged to 8-12 min from 3-5 min, and the gas cylinder 1 is arranged below the right side of the floatable diving suit and is used by 1 diver at a time. The 1.3L gas cylinder 1 adopts a steel cylinder, the inflation medium is air, and the highest inflation working pressure is 20 MPa.
The gas cylinder valve 2 is arranged on the gas cylinder 1 and controls the on-off of the gas outlet of the gas cylinder 1. When the cylinder valve 2 is opened, gas is supplied to the pressure reducer 3, and when the cylinder valve is closed, gas supply to the pressure reducer 3 is stopped.
The gas supply pipe 6 is made of a high-strength rubber pipe. One end of the air supply pipe 6 is communicated with the air outlet of the air bottle 1, and the other end is communicated with the air supply joint 8. The pressure reducer 3 is arranged on the gas supply pipe 6 and is used for reducing the pressure of high-pressure gas in the 1.3L gas cylinder to 0.8-1MPa higher than the ambient pressure. The air supply connector 8 may be connected to the suit connector 140 to inflate the interior of the suit body 100.
The three-way joint 4 is interposed between the gas supply pipe 6 and the pressure reducer 3. One end of the three-way joint 4 is connected with the outlet of the pressure reducer 3 through threads, and the other end of the three-way joint is connected with the air supply pipe 6. The air supply switch 5 is connected by threads and arranged at the third end of the three-way joint 4, and the three-way joint 4 is adjusted, so that the on-off and the air supply quantity of the air supply pipe 6 are adjusted, and the inflation state is finally controlled.
The air supply joint 8 is composed of a connecting plug 8-1 and a right-angle elbow 8-2. The air inlet of the elbow bend 8-2 is connected with the air supply pipe 6 through threads. The connector plug 8-1 can be screwed to the suit connector 140 of the floating suit to supply air inwards.
The working process of the floatable escape suit and the emergency air supply device of the escape suit comprises the following steps:
under normal conditions, the floatable escape suit 100 is inflated in the head breathing bag 110 through the inflation connector 120 in the fast pressurization cabin, so as to be used for the diver to breathe during the escape process.
When the gas supply is insufficient or the equipment breaks down in the danger escaping process during the rapid pressurization in a large depth, the gas supply is insufficient, the 110 gas quantity of the head breathing gas bag is caused, the gas bottle valve 2 is opened when the breathing gas can not be effectively provided for the persons in danger, the gas supply switch 5 is adjusted, the gas in the gas bottle 1 is decompressed through the decompressor 3, and the gas is inflated into the head breathing gas bag 110 through the gas supply pipe 6, the gas supply connector 8 and the diving suit connector 140, so that the diver can normally breathe. At this time, the switch 170 closes the passage between the suit connector 140 and the float airbag 160 and opens the passage between the suit connector 140 and the head airbag 110.
When the diver reaches the water surface, the switch 170 closes the passage between the suit connector 140 and the head breathing bag 110, and the diver opens the head breathing bag 110 to allow normal breathing. The switch 170 opens the passage between the diving suit connector 140 and the floating airbag 160, and the diving suit emergency air supply device inflates the floating airbag 160, thereby increasing the buoyancy of the diving suit.
Of course, in case the head breathing bag 110 is sufficient during the diver's ascent, the switch 170 closes the passage between the suit connector 140 and the head breathing bag 110, opens the passage between the suit connector 140 and the floating bag 160, and inflates the floating bag 160 in the water, accelerating the ascent speed, helping the diver to escape more quickly.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
