Detailed Description

The technical scheme protected by the utility model is specifically explained in the following by combining the attached drawings.

As shown in fig. 1 and 2, the safety self-rescue device for underwater use comprises: breathing mask 6, respectively with breathing mask 6 parallel connection's oxygen generator 1, gas bag 2 and reserve oxygen cylinder 3, be connected through trachea adapter 4 and trachea 5 respectively between oxygen generator 1, gas bag 2, reserve oxygen cylinder 3, the breathing mask 6. The breathing mask 6 is used for being worn by a person for breathing, and is respectively connected with the oxygen generator 1, the inflatable bag 2 and the standby oxygen bottle 3, the gases in the oxygen generator 1, the inflatable bag 2 and the standby oxygen bottle 3 form a whole, the oxygen generator 1 and the standby oxygen bottle 3 are used for providing oxygen for breathing of the person, the exhaled gas is filled into the inflatable bag 2, and the inflatable bag 2 can be bound to the person and used for providing buoyancy for the person to float upwards.

As shown in fig. 3, in order to prevent the oxygen generator 1 from malfunctioning, a spare oxygen cylinder 3 is provided, and compressed gas is used in the spare oxygen cylinder 3, so that a certain amount of oxygen can be provided although the volume is small, and the survival probability of people is improved. The standby oxygen cylinder 3 includes: compressed oxygen jar 31, drive arrangement, fixed compressed oxygen jar 31 and drive arrangement's fixing base 33, compressed oxygen jar 31 bottleneck department is provided with trachea quick-operation joint 34, drive arrangement can drive trachea quick-operation joint 34 and open compressed oxygen jar 31. The driving device comprises a motor, a motor shell 32 for placing the motor and a push rod 37 driven by the motor, wherein the push rod 37 is arranged in a way of aligning with the quick connector 34 of the trachea, when the motor is started, the push rod 37 extends out of the quick connector 34 of the trachea to open the compressed oxygen tank 31, and oxygen enters the trachea 5 from the trachea interface 35 so as to be breathed by a human body.
