TECHNICAL FIELD

[0001] The present application relates to the technical field of marine lifesaving equipment, in particular to a novel underwater 30-meter diving and ascending device. BACKGROUND

[0002] Due to frequent floods in recent years and the difficulty of rescue after falling into the sea, the rescue personnel's rescue skills are strictly required, and there is no underwater rescue equipment for water depth of 0-30m, so it is urgent to design a portable lifesaving equipment for underwater 30-meter single-person operation, which can be used for lifesaving by people who cannot swim.

[0003] At present, in the field of underwater rescue and diving operation, when the diver's own gas source is exhausted or the companion has an accident (such as equipment failure, injury, or getting lost), it is extremely challenging to implement effective underwater rescue. The traditional companion symbiotic rescue method usually relies on two divers sharing one breathing apparatus and alternating ascending. This method has significant risks: first, the rescue process is tense and hurried, and it is easy to cause both parties to choke or drown due to coordination failure; second, the ascending process cannot be effectively controlled, and it may cause decompression sickness due to ascending too fast, posing a serious threat to the diver's life; finally, for the rescued person who has lost consciousness, the traditional symbiotic rescue method is almost impossible to implement, because the rescuer is difficult to maintain his own safety while dragging an unconscious companion and ascending at a safe speed.

[0004] To solve the above problems, we propose a novel underwater 30-meter diving and ascending device to solve the above problems. SUMMARY

[0005] To solve the problems in the background art, the present application provides a novel underwater 30-meter diving and ascending device.

[0006] To achieve the above-mentioned purposes, the technical solution adopted by the present application is as follows: A novel underwater 30-meter diving and ascending device, comprising a wearable device and a life support assembly, the life support assembly comprising a high-pressure air bottle, the output end of the high-pressure air bottle being provided with a gas delivery pipeline, the distal end of the gas delivery pipeline being provided with a rescuer gas supply pipeline and a rescued person gas supply pipeline; the distal end of the rescuer gas supply pipeline is provided with a rescuer breathing mask, and the distal end of the rescued person gas supply pipeline is provided with a plurality of semi-closed breathing masks and safety airbags, the safety airbags are provided with a plurality of handles, and the handles are provided with a plurality of rescue ropes; wherein, when the safety airbags are inflated, the internal pressure of the safety airbags needs to reach 0.3MPa.

[0007] Preferably, the inlet end of the rescuer gas supply pipeline is provided with an electromagnetic valve.

[0008] Preferably, a filter and a balance valve are provided on the gas inlet pipeline of each of the plurality of semi-closed breathing masks.

[0010] Preferably, a hand valve is arranged on the top of the high-pressure air bottle, the hand valve is used for controlling the opening and closing of the air injection pipeline of the high-pressure air bottle, and the inflation valve is used for controlling the opening and closing of the air supply pipeline.

[0011] Compared with the prior art, the present application has the following beneficial effects: In the present application, the air supply, buoyancy lifting and towing functions are integrated, so that the rescuer does not need to drag the rescued person while exhausting physical strength, and also does not need to perform complex breathing apparatus sharing operation, only needs to wear a semi-closed breathing mask for the rescued person and fix it on the airbag, and then inflates the airbag, so that the airbag buoyancy is used to easily complete the rising, avoids the rescue risk of the rescuer, helps to reduce the potential risk caused by insufficient rescue ability of the rescuer, greatly reduces the requirements for physical strength and technology of the rescuer, makes the rescue action more efficient and reliable, and is especially suitable for rescuing unconscious divers, improves the rescue efficiency and success rate, and reduces the burden of the rescuer. In the present application, by providing double independent and continuous life support, the rescue device is provided with independent rescuer air supply pipeline and rescued air supply pipeline, and can provide stable air source for the rescuer and the rescued person (can support multiple people) at the same time, which ensures that the breathing of both parties is not interfered with in the whole diving process, avoids the risk of breathing interruption caused by the use of one breathing apparatus by both parties, especially ensures that the unconscious rescued person can obtain continuous and reliable air supply, fundamentally solves the risk and uncertainty caused by breathing alternation in traditional symbiotic rescue, and improves the rescue success rate.

DETAILED DESCRIPTION

[0014] The technical solution in this application embodiment is to solve the problems of the background technology mentioned above. The overall idea is as follows: The present invention is simple to operate. By inflating the airbag 13, it can float up on its own and simultaneously lift both the rescuer and the person being rescued to the surface. This helps to reduce the potential risks caused by the rescuer's insufficient rescue capabilities and avoids the rescuer's rescue risks. At the same time, in view of the possibility that underwater personnel cannot be rescued immediately, the device of the present invention is equipped with a semi-closed breathing mask 10, which plays a role in life support, allowing the person being rescued to breathe underwater, and facilitating the rescuer to complete multiple rescue operations in a short period of time. In addition, the airbag 13 provides the main buoyancy for ascent, and combined with multiple semi-closed breathing masks 10, it enables a single rescuer to easily tow and provide life support to one or more (including unconscious) people to complete the ascent, thereby solving the problem of the difficulty in rescuing unconscious divers.

[0015] Example: Refer to Figure 1 As shown, a novel underwater 30-meter diving device in this embodiment includes a wearable device 1 and a life support component. The life support component includes a high-pressure air cylinder 2. The output end of the high-pressure air cylinder 2 is provided with an air supply line 5. The ends of the air supply line 5 are respectively provided with a rescuer air supply line 6 and a rescued air supply line 9. The rescuer's air supply line 6 is equipped with a rescuer's breathing mask 8 at the end, and the rescued air supply line 9 is equipped with multiple semi-closed breathing masks 10 and safety airbags 13 at the end. Multiple handles 14 are installed on the safety airbags 13, and rescue ropes are installed on each of the multiple handles 14. The multiple handles 14 and rescue ropes enable multiple people to be rescued.

[0016] Wearable device 1 includes a lightweight vest, which is mainly used to comfortably and securely attach components such as high-pressure air cylinder 2, tubing and airbag 13 to the rescuer, ensuring that he can move freely in the water.

[0017] This device is not simply a single-person diving apparatus, but a dual-mode, multi-mission underwater rescue system. Its core innovation lies in integrating the rescuer's own life support with the life support and rapid ascent capability for the rescued person into a single portable unit. This solves the problem in traditional one-on-one rescues where the rescuer has limited air supply and it is difficult to ensure the safe ascent of both parties simultaneously.

[0018] Specifically, when inflating the airbag 13, the internal pressure of the airbag 13 needs to reach 0.3 MPa to ensure that the airbag can be fully deployed and provide sufficient positive buoyancy at a water depth of 30 meters (the ambient pressure is about 0.4 MPa). The internal pressure of 0.3 MPa is much higher than the hydrostatic pressure at a water depth of 30 meters, which means that the airbag will expand rapidly and generate a strong upward pull to overcome underwater resistance, the weight of the human body and the device, and achieve rapid ascent. This pressure value has also been calculated to ensure that the airbag structure will not rupture due to over-inflation.

[0019] In some examples, the inlet end of the rescuer's air supply line 6 is equipped with a solenoid valve 7. Opening the solenoid valve 7 allows air to be supplied to the rescuer's breathing mask 8.

[0020] In some examples, multiple sets of semi-closed breathing masks 10 are equipped with filters 11 and balance valves 12 on their air intake lines. The filters 11 are used to purify the air supplied to the rescued person, and may include functions such as dehumidification and filtering of fine particulate matter, so as to avoid secondary damage to the respiratory tract of the rescued person during the rescue. The core function of the balance valve 12 is to provide stable and appropriate pressure and flow of air to the semi-closed breathing mask 10 regardless of the pressure changes in the gas cylinder, so as to ensure that the rescued person can breathe comfortably and smoothly, and to ensure that the semi-closed circuit works normally, so as to achieve a stable air supply to the rescued person.

[0021] In some examples, the airbag 13 is equipped with a pressure reducing valve 16 and a one-way overflow valve 15 on its air intake line. The one-way overflow valve 15 can control the inflation speed to prevent the airbag from rising too quickly and causing negative effects on the person's body. The one-way overflow valve 15 can also prevent the airbag 13 from flowing back and ensure that the airbag 13 stops inflating when the gas pressure reaches 0.3 MPa.

[0022] In some examples, a hand valve 3 is provided on the top of the high-pressure air cylinder 2. The hand valve 3 is used to control the opening and closing of the air filling pipeline of the high-pressure air cylinder 2. Opening the hand valve 3 makes it easy to fill the high-pressure air cylinder 2 with air. When in use, the hand valve 3 needs to be closed to avoid air leakage. The filling valve 4 is used to control the opening and closing of the air supply pipeline 5. Opening the filling valve 4 allows the gas in the high-pressure air cylinder 2 to be delivered to the outside.

[0023] In some examples, all valves in this invention are manually operated and hydraulically driven switches; the maximum number of people that can be rescued at one time is limited to 10.

[0024] The working principle of this invention is: When a rescue operation is needed, the rescuer first carries the high-pressure air cylinder 2 through the wearable device 1, then closes the hand valve 3 of the high-pressure air cylinder and opens the inflation valve 4 to supply air to the air supply line 5. Then, the rescuer puts on the breathing mask 8 and opens the solenoid valve 7 at the inlet end of the air supply line 6 so that the rescuer can breathe freely in the sea. When the rescuer descends to the person being rescued, they first tie the rescue rope to the person being rescued and help the person put on a semi-closed breathing mask 10. At the same time, they need to open the balance valve 12 so that gas can be delivered through the filter 11 and the balance valve 12 to the semi-closed breathing mask 10 for the person being rescued to breathe.

[0025] Once everyone has completed the rescue, the pressure relief valve 16 and the one-way overflow valve 15 can be opened to inflate the airbag 13. During the inflation process, the one-way overflow valve 15 can control the inflation speed to prevent the person from rising too quickly and having a negative impact on their body. At the same time, it can also prevent the gas in the airbag 13 from flowing back and ensure that the inflation stops when the gas in the airbag 13 reaches 0.3 MPa. As the airbag 13 inflates, it can help the rescuer and the person being rescued to rise to the surface until they float to the surface, thus completing the rescue mission.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
