Abstract
Description
[0001] The invention relates to the field of diving technology, namely to devices that provide closed circulation, control and regeneration of the breathing gas environment in a sealed facility.
[0002] The “Device for automatic maintenance and control of the composition of the breathing gas environment of a diving bell” is known, designed to automate the process of maintaining and controlling the composition of the breathing gas environment of a diving bell, reducing the workload on the bell operator and providing the ability to control the oxygen supply to the diving bell from the control post of the diving descent [1].
[0003] The disadvantages of the device when used in other sealed objects, such as a pressure chamber compartment or an autonomous rescue bell, are:
[0004] - the need to provide power supply (the device does not have its own power source);
[0005] - the ability to control the operation of the device only from the surface (inside the bell, control of the device is possible only in emergency mode - manual control of the oxygen supply by the bell operator);
[0006] - stationary design of the device, which does not allow its use in other sealed objects after installation;
[0007] - the need to make changes to the design of the sealed object to ensure the possibility of using the device.
[0008] The objective of the invention is to provide the ability to automate the process of maintaining the partial pressure of oxygen in the breathing gas environment of any hermetically sealed object without making changes to its design.
[0009] The problem is solved by using an "Autonomous Device for Automatic Maintenance and Control of the Composition of the Breathing Gas Environment" to maintain the required partial oxygen pressure in the breathing gas environment, pre-formed in the containment facility. It consists of an absorption cartridge filled with a chemical limestone absorbent, with a fan providing forced gas circulation through the cartridge. The cartridge volume and fan performance are selected based on the internal volume of the containment facility and the number of people accommodated within. The device is also equipped with a partial oxygen pressure sensor unit, which analyzes the composition of the breathing gas environment in real time and transmits a signal to the controller, which processes it and outputs it to the input / output device.If the partial pressure of oxygen drops below a preset value, the device's controller signals the opening of the solenoid valve and the release of a portion of oxygen from a high-pressure oxygen cylinder. The cylinder's volume is determined based on the number of people accommodated in the containment facility. The device is powered by a standalone battery. Manual oxygen supply is provided in the event of a solenoid valve failure.
[0010] The device is placed in a sealed facility so as to ensure free flow of gas to the air duct and visual monitoring of the I / O unit. Additionally, depending on operating conditions, the device can be equipped with a rigid protective housing, a stand, or a suspension system.
[0011] The essence of the invention is that it provides the ability to automate the process of maintaining the partial pressure of oxygen in the breathing gas environment of any hermetically sealed object without making changes to its design.
[0012] The advantage of the invention is to ensure automation of the process of maintaining the partial pressure of oxygen in the breathing gas environment of any hermetically sealed object without making changes to its design.
[0013] The use of the invention will make it possible to maintain the required partial pressure of oxygen in the breathing gas environment of any hermetically sealed object without making changes to its design.
[0014] Figure 1 shows the device of the invention, which consists of an absorption cartridge 2, at the bottom of which a fan 1 is connected, and at the top of which a head unit 3, inside which oxygen partial pressure sensors 4 and a controller 5 are located. The controller 5 is connected to the information input-output device 6, the battery 7 and the electromagnetic valve 14, through which a metered supply of oxygen is carried out from a high-pressure cylinder 12, equipped with a shut-off valve 10, a reducer 9, a pressure gauge 13 with a high-pressure hose 11 and a medium-pressure hose 8. The electromagnetic valve 14 is equipped with a device for its mechanical opening (a forced oxygen supply button) 15.
[0015] Figure 2 shows a general view of the invention, which consists of a compartment with a fan 1, an information input-output device 2, a head unit 3, a high-pressure oxygen cylinder 4, a battery 5; a shut-off valve 6; a reducer 7; an oxygen pressure gauge with a high-pressure hose 8, an electromagnetic valve with a forced oxygen supply button 9 and an air duct with a protective mesh 10.
