Abstract

The proposed device for controlling the diver’s breathing refers to the safety of diving descents and can be used for diving breathing apparatus with air supply from the surface. The diver’s breathing control device contains a sensor that controls the movement of air passing through the breathing apparatus system with air supply from the surface, an electric lamp located above the water surface, connected to a constant voltage source through the output contact of the sensor that detects the movement of air mounted above the water surface on the end of the hose connecting the breathing machine held by the diver's mouth and the surface of the breathing apparatus. The technical result achieved by the proposed device is the absence of water in the sensor that controls the movement of air, due to its location above the surface of the water.

Description

The proposed solution relates to the safety of diving descents and can be used for diving breathing apparatus with air supply from the surface.

A device is known for controlling a diver’s breathing (see USSR author’s certificate No. 431063), which contains an alarm block, a sensor that controls the movement of air passing through the breathing apparatus, located in a breathing machine for air supply or in a special valve box that issues periodic signals to the block emergency alarm.

The technical result not achieved by the above analogue is the absence of water in the sensor that controls the movement of air.

The reason for the impossible achievement of the technical result indicated above is that the sensor that controls the movement of air is located in a breathing machine or in a special valve box, in an aqueous medium, which can cause water to enter and cause the device to malfunction.

The technical result indicated above is achieved by the fact that the diver’s breathing control device contains a sensor that controls the movement of air passing through systems of a breathing apparatus having air supply from the surface, a signal lamp located above the water surface, connected to a constant voltage source through the output the contact of the sensor that controls the movement of air mounted above the surface of the water at the end of the hose connecting the breathing machine held by the diver’s mouth and the surface hour s breathing apparatus.

The implementation of the device for controlling the diver’s breathing, as described above, prevents the ingress of water into the sensor that controls the movement of air and the failure of the device.

The proposed device for controlling the breath of a diver is illustrated by the following description and graphic images, which shows the design of the device.

The diver’s breathing control device contains:

- source of compressed air-1;

- a hose-2 for supplying air from the surface of water-3, connected by its inlet to a source of compressed air-1;

- breathing machine-4 consisting of:

- inlet valve-5, connected by its inlet to the outlet of the hose-2;

- exhaust valve-6;

- diaphragm-7, sensitive to environmental pressure associated with the inlet valve-5 lever-8;

- a sensor-9 that controls the movement of air mounted above the surface of the water-3 at the inlet end of the hose-2 of air supply to the diver from the surface of the water-3;

- an electric lamp-10 located above the surface of the water-3;

- a constant voltage source-11 connected to an electric lamp-10 through the output contact of the sensor-9, which controls the movement of air.

The V6EPB-B-S-LF flow switch V6 series for low flow from Flotect®, published on the website www.olil.ru, can be used as a sensor controlling air movement.

The proposed device for controlling the breath of a diver works as follows.

At the moment of the diver's inspiration, the diaphragm-7 is deformed into the body of the breathing machine-4, opening the intake valve-5 through the lever-8. Air from a source of compressed air-1 enters through the hose-2 into the diver's lungs. The air flow passing through the sensor-9, which controls the movement of air, causes the output contacts to close, the electric lamp-10 receives power from a constant voltage source-11 and its glow occurs.

At the moment the diver exhales, the diaphragm-7 of the inspiration returns to its original state, the inlet valve-5 closes, blocking the flow of air into the hose-2. The air flow in the sensor-9, which controls the movement of air, disappears and its output contact returns to its original position, opening the contacts, and the electric lamp-10 goes out. In this case, the diver exhales air into the environment through the exhaust valve-6. Further, the process will be repeated with each inhalation and exhalation, which will inform the electric lamp-10. If the electric lamp-10 burns continuously or goes out continuously, this will be a signal to the rescue personnel to immediately save the diver.

The proposed control device of the diver’s breathing allows you to prevent water from entering the sensor, which records the movement of air, due to its location above the water surface.
