Description

Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen chamber structures, and more specifically, to a hyperbaric oxygen chamber with a fire source detection function. Background Art

[0002] Hyperbaric oxygen chamber fire is a rare but possible emergency. This type of fire is very dangerous, mainly because the high oxygen concentration in the chamber makes some substances that will not ignite in air at normal pressure become extremely easy to ignite in a hyperbaric oxygen environment. When high-concentration oxygen encounters substances such as hydrocarbons, grease, and pure polyester, it may even cause spontaneous combustion. Once a fire occurs, the high oxygen concentration in the chamber will not only cause extremely serious burns, but also the combustion will be very complete. The fire will spread rapidly, quickly depleting the oxygen in the chamber, causing acute hypoxia and suffocation.

[0003] The occurrence of hyperbaric oxygen chamber fires is usually related to multiple factors. Improper fire source management is also a common cause. Open flames, static sparks, and carried fire sources such as lighters may become fire sources, causing fires and posing a serious threat to personnel and equipment in the cabin.

[0004] Therefore, although the probability of a hyperbaric oxygen chamber fire is relatively small, its potential hazards cannot be ignored. Inventing a hyperbaric oxygen chamber with a fire source detection function is very important for doctors' diagnosis and treatment, patients' safety, and equipment stability. Utility Model Content

[0019] The structure provided by the utility model is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0020] refer to Figure 1 and Figure 2 As shown, this embodiment specifically discloses a hyperbaric oxygen chamber with a fire source detection function, including a cabin body 1 and a controller 3, a cabin door 2 is opened on the cabin body 1, vertical plates 4 are arranged on the left and right sides of the cabin door 2, and the upper and lower sides between the left and right vertical plates 4 are connected by a horizontal strip 5, a metal detection coil 6 is installed in one of the vertical plates 4, a coil detection receiver 7 is installed in the other vertical plate 4, and a sensing device and an alarm 8 are installed in the horizontal strip 5; the coil detection receiver 7, the sensing device and the alarm 8 are all connected to the controller 3 by signal, including but not limited to wireless communication connection and wired data connection; the sensing device can be an infrared detector or an image capture device, etc., for detecting whether someone passes through the cabin door 2; the coil detection receiver 7 is used to receive the electromagnetic wave signal emitted by the metal detection coil 6, and transmit the received electromagnetic wave signal to the controller 3, and the controller 3 is used to control the metal detection coil 6 to work according to the detection result of the sensing device, and control the alarm 8 to work according to the received electromagnetic wave signal.

[0021] Specifically, in this embodiment, the sensing device uses an infrared detector for detection, that is, the sensing device is a first infrared detector 9, which is installed on the outside of the horizontal slat 5 located on the upper side, and the controller 3 can also be installed in the horizontal slat 5 on the upper side. It should be noted that the working principle of the infrared detector is mainly based on the interaction between the infrared radiation emitted by the object and the infrared detector. Specifically, the infrared detector receives the infrared radiation emitted by the object and converts it into an electrical signal output. When someone passes through the cabin door 2 and is about to enter the cabin 1, the first infrared detector 9 can detect the infrared radiation emitted by the human body, thereby converting it into an electrical signal and outputting it to the controller 3. The controller 3 can determine that someone is about to enter the cabin 1, and then control the metal detection coil 6 to start, that is, to energize, so as to detect the human body and determine whether the human body carries dangerous fire items such as lighters. If it is detected, the alarm 8 is controlled to start, and a sound or light prompt alarm is issued to avoid bringing the person into the cabin 1.

[0022] It should be noted that, in this embodiment, when the metal detection coil 6 is energized, a magnetic field will be generated around it, and an electromagnetic wave signal will be emitted. When a dangerous fire containing metal objects is carried by a human body, eddy currents will be generated in the metal objects due to electromagnetic induction. These eddy currents will further generate a magnetic field, thereby affecting the original magnetic field. The coil detection receiver 7 can detect the change in the magnetic field signal, that is, the change in the electromagnetic wave signal, and then transmit the change signal to the controller 3. The controller 3 can determine that the dangerous fire containing metal objects is carried by the human body, and then control the alarm 8 to start.

[0023] The controller 3 may be a PLC (Programmable Logic Controller), which may also include a remote control unit, etc., that is, it may remotely control the start or shut down of each component.

[0024] Continue to refer Figure 1 and Figure 2 In some embodiments, it also includes a second infrared detector 10 and a third infrared detector 11 arranged in the transverse slat 5, and the second infrared detector 10 and the third infrared detector 11 are both connected to the controller 3 by signal, wherein the second infrared detector 10 and the third infrared detector 11 are both installed in the transverse slat 5 located on the upper side, and the second infrared detector 10 can be installed on the inner side of the transverse slat 5 to monitor the temperature inside the cabin 1. When the internal temperature is detected to be abnormal, the abnormal signal is transmitted to the controller 3, and the controller 3 can control the alarm 8 to start and give an alarm prompt; similarly, the third infrared detector 11 can be installed on the outer side of the transverse slat 5 to monitor the temperature outside the cabin 1. When the external temperature is detected to be abnormal, the abnormal signal is transmitted to the controller 3, and the controller 3 can control the alarm 8 to start and give an alarm prompt.

[0025] Furthermore, in some embodiments, a first smoke detector 12 and a second smoke detector 13 are also provided in the transverse slat 5 located at the upper end. The first smoke detector 12 and the second smoke detector 13 are also connected to the controller 3 by signal. The first smoke detector 12 is installed on the inner side of the upper transverse slat 5, and is used to detect the smoke condition inside the cabin 1. When abnormal smoke is detected inside, the abnormal signal is transmitted to the controller 3, and the controller 3 can control the alarm 8 to start and give an alarm prompt; the second smoke detector 13 is used to detect the smoke condition outside the cabin 1. When abnormal smoke is detected outside, the abnormal signal is transmitted to the controller 3, and the controller 3 can control the alarm 8 to start and give an alarm prompt.

[0026] In this embodiment, infrared detectors and smoke detectors are provided simultaneously to jointly detect the inside and outside of the cabin, thereby ensuring the accuracy and safety of the detection.

[0027] In some embodiments, Figure 1As shown, the cabin 1 is also provided with a plurality of lockers 14 on the left and right sides of the cabin door 2; the lockers 14 are provided so that the medical staff or patients who enter can put the detected dangerous fire sources therein conveniently, and can also take them away after leaving, which is convenient to take and can also ensure the safety requirements in the cabin 1.
