Description

Technical Field

[0001] The present invention relates to the technical field of hyperbaric oxygen chamber equipment, and particularly relates to a hyperbaric oxygen chamber facilitating emergency evacuation. Background Art

[0002] A hyperbaric oxygen chamber is a device that increases the environmental air pressure to improve the body's oxygen uptake, making oxygen more easily absorbed. It is mainly used in medical treatment, sports recovery, beauty, and other fields. Therefore, many rehabilitation hospitals are equipped with hyperbaric oxygen chambers, and the air pressure inside the hyperbaric oxygen chamber is higher than normal atmospheric pressure. Generally, the working pressure of a hyperbaric oxygen chamber can reach 1.3 - 1.5 atmospheres, or even higher. When the hyperbaric oxygen chamber is pressurized, the oxygen concentration inside is much higher than that of air under normal atmospheric pressure.

[0003] Although a fire inside a hyperbaric oxygen chamber is a less likely but still possible fire accident. Once a fire occurs in the hyperbaric oxygen chamber, its danger is much greater than that of a fire under normal atmospheric pressure. Due to the high oxygen concentration inside the chamber, some substances that are not easily ignited in air under normal atmospheric pressure become extremely easy to ignite in a high-pressure oxygen environment. For example, hydrocarbons, oils, pure polyester, etc., may even cause spontaneous combustion. Once a fire occurs, due to the high air pressure and oxygen concentration inside the chamber compared to normal atmospheric pressure, it will cause serious burns to the people in the oxygen chamber.

[0004] Therefore, although it is important to extinguish the fire after it occurs in the hyperbaric oxygen chamber, the most important thing is to ensure the safety of the people inside the chamber first. Therefore, it is very necessary to consider in the design of the hyperbaric oxygen chamber that people can safely and quickly escape from the fire danger after a fire occurs inside the oxygen chamber. Summary of the Invention

[0005] The present invention aims to provide a hyperbaric oxygen chamber facilitating emergency evacuation to achieve the purpose of quickly evacuating people when a fire occurs in the hyperbaric oxygen chamber.

[0006] To achieve the above purpose, the technical solution provided by the present invention is: A hyperbaric oxygen chamber facilitating emergency evacuation, including a cabin body for multiple people to use at one time. The side wall of the cabin body bulges outwards to form a plurality of independent semi-cabins. A channel communicating with the internal space of the cabin body is formed inside the semi-cabins. A rotating platform is installed on the ground of the semi-cabins, and a treatment seat is fixed on the rotating platform. A sealing door for blocking the channel between the semi-cabin and the cabin body is fixed at the edge of the rotating platform on the backrest side of the treatment seat. An independent fire extinguishing nozzle is provided inside the semi-cabin, and an escape opening is provided on the outer wall of the semi-cabin. An emergency evacuation door is installed at the escape opening; it also includes an infrared imaging camera for detecting a fire source and a controller for processing image signals. When the controller receives the image signal from the infrared imaging camera and discovers a fire point, it controls the rotating platform to rotate, makes the sealing door block the channel between the semi-cabin and the cabin body, and starts the fire extinguishing nozzle to spray fire extinguishing agent into the treatment seat.

[0007] The principle and advantage of this solution are: in this hyperbaric oxygen chamber, multiple people can be accommodated into the chamber at the same time, each of which is equipped with an independent treatment seat. After the user enters the oxygen chamber body, he enters the half-cabin from the passage, sits on the treatment seat, and uses the oxygen mask provided on the upper end of the treatment seat for oxygen supply.

[0008] When a fire occurs in the cabin, the infrared imaging camera detects the fire source. At this time, the controller controls the motor that drives the turntable to rotate, allowing the turntable to quickly rotate 180°. At this time, the user and the treatment chair are enclosed in the half cabin, and the pressure relief device in the hyperbaric oxygen chamber is used to relieve the pressure on the cabin and the half cabin. After the pressure relief is completed, the user completes the evacuation from the emergency evacuation door.

[0009] During the whole process, by automatically detecting whether there is a fire in the cabin, if the fire point is in the non-half cabin area, the rotating table can be quickly controlled to rotate. After rotating, the sealing door quickly seals the passage between the half cabin and the cabin to prevent the flames in the cabin from entering the half cabin. In addition, regardless of whether there is a fire source in the half cabin, the fire extinguishing nozzle is forced to start spraying the fire extinguishing agent in the half cabin; in this way, even if there is no fire source in the half cabin, the fire extinguishing agent can be used as a precaution to prevent the flames from entering the half cabin and causing combustion; if the fire point is in the half cabin or there is a fire source in the half cabin, it can also be quickly extinguished by the fire extinguishing agent.

[0010] During this process, the hyperbaric oxygen chamber's built-in pressure relief system is used to relieve pressure in the cabin and half of the cabin at the same time. After the pressure relief is completed, the user quickly evacuates from the emergency evacuation door.

[0011] Preferably, one side of the sealing door used for blocking the passage is covered with a flexible fireproof layer, the flexible fireproof layer is filled with fireproof cotton inside, and the fireproof cotton is wrapped with a layer of glass fiber fireproof cloth outside.

[0012] As an object separating the cabin and the half-cabin, the sealing door itself must meet the fire resistance requirements. At the same time, a flexible fireproof layer is covered on one side of the sealing door used to block the passage, so that the sealing door and the rotating table rotate synchronously. The flexible fireproof layer can be squeezed and deformed, so that the rotating table is not stuck in the path of the sealing door during the rotation process. In addition, when the rotating table is fully rotated into place, the flexible fireproof layer expands, so that the sealing door completely blocks the half-cabin passage, preventing the flames in the cabin from entering the half-cabin.

[0013] Preferably, the rotation center of the rotating table is eccentric to one side of the cabin body by at least 5 mm. The rotation center of the rotating table is eccentric to one side of the cabin body, so that during the rotation of the rotating table, the sealing door is closer to the passage in the direction of the rotating table diameter, and after rotating into place, the sealing door blocks the passage more tightly.

[0014] Preferably, a pressure relief chamber is provided on the bottom surface of the cabin, and the pressure relief chamber is communicated with the half cabin and the cabin body. The pressure relief chamber is connected to a pressure relief pipe, and an electric pressure relief valve is connected to the pipe. When the controller receives an image signal from the infrared imaging camera and finds a fire point, it controls the electric pressure relief valve to open to relieve the pressure in the hyperbaric oxygen chamber.

[0015] A pressure relief chamber is set at the bottom of the cabin. The pressure relief chamber can not only quickly discharge the high-pressure air in the cabin, but also, when a fire occurs, after the pressure relief valve is opened, since the pressure relief chamber is at the bottom, the high-pressure gas will drive smoke, water vapor and other substances to be discharged from the bottom of the cabin. The flame is attracted by the negative pressure to prevent it from moving to the top of the cabin.

[0016] Preferably, the emergency evacuation door is equipped with a safety lock, the lock pin of the safety lock is connected to a lock pin motor, and an air pressure sensor is installed in the half cabin. After the air pressure sensor detects that the air pressure in the half cabin is depressurized, the lock pin motor opens the safety lock to put the emergency evacuation door in a freely open state. Due to the existence of the safety lock, the emergency evacuation door is prevented from being dangerously opened before the pressure relief is completed.

[0017] Preferably, an independent emergency pressure relief valve is installed on the half cabin, and the emergency pressure relief valve is opened by an operating rod arranged outside the emergency evacuation door, and the linkage mechanism drives the emergency evacuation door to open. Through the independent emergency pressure relief valve, the emergency pressure relief valve can be opened outside the hyperbaric oxygen chamber to accelerate the pressure relief, and the problem of failure of the pressure relief valve of the cabin body to relieve pressure can also be avoided.

[0018] Preferably, the emergency evacuation door is a high-strength transparent tempered glass door. Through the transparent glass door, it is convenient for rescuers to observe the status of the user in the half-cabin outside the oxygen chamber, so as to facilitate further taking other emergency measures.

[0019] Preferably, the fire extinguishing nozzles are arranged on both sides of the armrests of the treatment seat, and the fire extinguishing nozzles are connected to gas nozzles. The gas nozzles are connected to a gas storage device for storing IG541 mixed gas through gas valves and pipelines. A control button for opening the gas valve is provided on the armrests of the treatment seat. When the controller receives the image signal of the infrared imaging camera and the control button signal at the same time, the gas valve is opened to allow the IG541 mixed gas to be quantitatively ejected from the gas nozzle.

[0020] The IG541 mixed gas introduced into the fire extinguishing nozzle is a mixture of nitrogen, argon and carbon dioxide in proportion. It is a non-toxic, colorless, odorless, non-conductive inert gas fire extinguishing agent. It acts in the half cabin to avoid harm to the human body. In addition, the fire extinguishing nozzle is set on both sides of the armrest of the treatment seat. When the fire extinguishing nozzle sprays the fire extinguishing agent, it can completely cover the entire treatment seat range and completely extinguish the flames.

[0021] Preferably, a spraying system is provided at the top inside the cabin, including a plurality of pressurized nozzles and atomizing nozzles. The pressurized nozzles are distributed at the top of the inner wall of the cabin, and the pressurized nozzles are connected to the top of the inner wall of the cabin through a pan-tilt base. The pan-tilt base is driven by a motor. The atomizing nozzle is installed at the top of the cabin above the half-cabin, and the spraying direction of the atomizing nozzle is fixed downward. The controller receives the image signal of the infrared imaging camera, controls the pan-tilt base to rotate by a corresponding angle, aligns the pressurized nozzle with the fire source, and simultaneously turns on the atomizing nozzle to continuously spray the sealed door.

[0022] The fire extinguishing liquid can directly reach the ignition point through the pressurized nozzle, enabling targeted fire extinguishing. The addition of the atomizing nozzle is to cool the inside of the cabin and the half-cabin, and to assist in extinguishing the existing fire source.

[0023] Preferably, a liquid discharge slit is provided at the bottom surface of the cabin, a confluence trough is provided below the liquid discharge slit, and a sewage pipe is connected to the lowest part of the confluence trough. A sewage valve is connected to the sewage pipe.

[0024] During the process of controlling and extinguishing the fire by the spraying system, the generated liquid flows away through the liquid discharge slit, converges in the confluence trough, and finally is discharged through the sewage pipe, avoiding the problem of sewage deposition in the mobile cabin after fire extinguishing.

Detailed Description of the Invention The following is further detailed through specific embodiments, but the embodiments of the present invention are not limited thereto. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art.

[0028] Embodiment 1 As Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown, a hyperbaric oxygen chamber facilitating emergency evacuation has a long tubular structure. The interior of the chamber body 1 can accommodate multiple people at one time. One end of the chamber body 1 is provided with a hatch 12 for entering the chamber. Both side walls of the chamber body 1 bulge outward to form a plurality of independent half-chambers 2. A passage communicating with the interior space of the chamber is formed inside the half-chambers 2. A rotating platform 7 is installed on the ground of the half-chamber 2. A treatment seat 6 is fixed on the rotating platform 7. A sealing door 61 for blocking the passage between the half-chamber and the chamber is fixed at the edge of the rotating platform 7 on the backrest side of the treatment seat 6. An independent fire sprinkler 62 is provided inside the half-chamber 2. An emergency exit is provided on the outer wall of the half-chamber 2, and an emergency evacuation door 3 is installed at the emergency exit; An infrared imaging camera for detecting a fire source and a controller for processing image signals are also provided in the chamber body. When the controller receives the image signal of the infrared imaging camera and detects a fire point, it controls the rotating platform 7 to rotate so that the sealing door blocks the passage between the half-chamber and the chamber body. And the fire sprinkler 62 is activated to spray a fire extinguishing agent into the treatment seat 6.

[0029] The fire sprinkler 62 is arranged on both sides of the armrest of the treatment seat 6. The fire sprinkler 62 is connected with a gas spray pipe. The gas spray pipe is connected to a gas storage device storing IG541 mixed gas through a gas valve and a pipeline. A control button 63 for opening the gas valve is provided on the armrest of the treatment seat 6. When the controller receives both the image signal of the infrared imaging camera and the signal of the control button 63, the gas valve is opened, so that the IG541 mixed gas is quantitatively ejected from the fire sprinkler 62.

[0030] A display screen 11 is installed on the outer surface of the top of the chamber body 1 for displaying alarm pictures and promotional pictures.

[0031] During the whole process, by automatically detecting whether there is a fire in the chamber body, if the fire point is in the non-half-chamber area, after the rotating platform rotates, the sealing door quickly seals the passage between the half-chamber and the chamber body to prevent the flames in the chamber body from entering the half-chamber. In addition, regardless of whether there is a fire source in the half-chamber, the fire sprinkler 62 is forcibly activated to spray a fire extinguishing agent into the half-chamber 2; In this way, even if there is no fire source in the half-chamber, the fire extinguishing agent can be used as a prevention to avoid flames from entering the half-chamber and causing combustion; If the fire point is in the half-chamber or there is a fire source in the half-chamber, it can also be quickly extinguished by the fire extinguishing agent.

[0032] The IG541 mixed gas introduced into the fire sprinkler 62 is composed of nitrogen, argon and carbon dioxide mixed in a certain proportion. It is a non-toxic, colorless, odorless and non-conductive inert gas fire extinguishing agent. Acting in the half-chamber, it can avoid harm to the human body. In addition, the fire sprinkler is arranged on both sides of the armrest of the treatment seat. When the fire sprinkler sprays the fire extinguishing agent, it can completely cover the entire range of the treatment seat and completely extinguish the flames.

[0033] During this process, the pressure relief system of the hyperbaric oxygen chamber is used to relieve pressure in the chamber and the half-chamber at the same time. After the pressure relief is completed, the user quickly evacuates from the emergency evacuation door. Of course, in this embodiment, even if the user fails to evacuate from the emergency evacuation door, the user will not be harmed by the fire because of the isolation of the sealed door.

[0034] The sealing door 61 is used to block the passage and one side thereof is covered with a flexible fireproof layer, wherein the flexible fireproof layer is filled with fireproof cotton inside and the fireproof cotton is wrapped with a layer of glass fiber fireproof cloth outside.

[0035] As an object separating the cabin and the half-cabin, the sealing door itself must meet the fire resistance requirements. At the same time, a flexible fireproof layer is covered on one side of the sealing door used to block the passage, so that the sealing door and the rotating table rotate synchronously. The flexible fireproof layer can be squeezed and deformed, so that the rotating table is not stuck in the path of the sealing door during the rotation process. In addition, when the rotating table is fully rotated into place, the flexible fireproof layer expands, so that the sealing door completely blocks the half-cabin passage, preventing the flames in the cabin from entering the half-cabin.

[0036] The emergency evacuation door 3 is equipped with a safety lock, the lock pin of which is connected to a lock pin motor, and an air pressure sensor is installed in the half cabin. After the air pressure sensor detects that the air pressure in the half cabin is depressurized, the lock pin motor opens the safety lock to put the emergency evacuation door in a free opening state. Due to the existence of the safety lock, the emergency evacuation door is prevented from being dangerously opened before the pressure relief is completed.

[0037] like Figure 1 As shown, an independent emergency pressure relief valve 5 is installed on the half cabin 2, and the emergency pressure relief valve 5 is opened by an operating rod 4 arranged outside the emergency evacuation door 3. Through the independent emergency pressure relief valve, the emergency pressure relief valve can be opened outside the hyperbaric oxygen chamber to accelerate the pressure relief. In addition, it can also avoid the problem that the pressure relief valve of the cabin body fails and cannot relieve pressure.

[0038] The emergency evacuation door 3 is a high-strength transparent tempered glass door. Through the transparent glass door, it is convenient for rescuers to observe the status of the user in the half cabin outside the oxygen cabin, so as to further take other emergency measures.

[0039] Example 2 like Figure 2 and Figure 3 As shown, a pressure relief chamber 9 is provided on the bottom surface of the cabin 1, and the pressure relief chamber 9 is communicated with the half cabin 2 and the cabin 1. The pressure relief chamber 9 is connected to a pressure relief pipe, and an electric pressure relief valve is connected to the pipe. When the controller receives the image signal of the infrared imaging camera and finds a fire point, it controls the electric pressure relief valve to open and relieve the pressure in the hyperbaric oxygen chamber. The pressure relief chamber 9 can not only quickly discharge the high-pressure air in the cabin. When the pressure relief valve is opened, since the pressure relief chamber 9 is on the bottom surface, the high-pressure gas will drive smoke, water vapor and other substances to be discharged from the bottom of the cabin, and the flame is attracted by the negative pressure to prevent it from moving to the top of the cabin 1.

[0040] Inside the top of the cabin body 1, there is a spraying system 8, which includes a plurality of pressurizing nozzles 81 and atomizing nozzles 82. The pressurizing nozzles 81 are distributed on the top of the inner wall of the cabin body. The pressurizing nozzles 81 are connected to the top of the inner wall of the cabin body through a pan-tilt base. The pan-tilt base is driven by a motor. The atomizing nozzles are installed on the top of the cabin body above the semi-cabin. The spraying direction of the atomizing nozzles 82 is fixed downward. The controller receives the image signal of the infrared imaging camera, controls the pan-tilt base to rotate by a corresponding angle, makes the pressurizing nozzles aim at the fire source, and at the same time opens the atomizing nozzles to continuously spray the sealed door.

[0041] On the bottom surface of the cabin body 1, there is a liquid drainage seam 14. Below the liquid drainage seam 14, there is a confluence trough 10. The lowest part of the confluence trough 10 is connected to a sewage discharge pipe 13, and a sewage discharge valve is connected to the sewage pipe 13. During the process of controlling and extinguishing the fire by the spraying system 8, the generated liquid flows away from the liquid drainage seam 14, converges into the confluence trough 10, and finally is discharged from the sewage pipe 13, avoiding the problem of sewage deposition in the cabin body after fire extinguishing.

[0042] The hyperbaric oxygen chamber of this embodiment is equipped with a conventional oxygen supply system and an internal state monitoring system of the hyperbaric oxygen chamber. The oxygen supply system and the monitoring system are not involved in the problems solved by this solution, and will not be elaborated here. The controller used in this embodiment is an industrial personal computer.

[0043] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
