Description

Technical Field

[0001] This utility model belongs to the field of rescue device technology, specifically relating to an oxygen supply device for underground rescue. Background Technology

[0002] In the event of sudden accidents such as mine collapses, gas leaks, or fires, the underground environment can become extremely harsh, especially with insufficient oxygen, which can easily threaten the lives of trapped personnel. Therefore, the development and application of underground rescue oxygen supply technology is of great significance.

[0003] Existing downhole oxygen supply systems present several problems in practical applications. Traditional systems typically require rescuers to personally carry oxygen equipment down into the well to provide oxygen to trapped personnel, or to drop oxygen cylinders to them. This not only increases the danger to rescuers but also leads to lower rescue efficiency. Furthermore, some remote oxygen supply systems are complex in design and cumbersome to operate, requiring lengthy preparation time during actual rescue operations, potentially wasting valuable rescue time. Moreover, existing systems often encounter difficulties in delivering oxygen downhole due to obstructed pipeline deployment or improper operation, making it difficult for trapped personnel to obtain breathing equipment in a timely manner, further complicating the rescue effort.

[0004] For rescuers: Faced with a narrow well opening, rescuers carrying oxygen equipment may be unable to descend or may easily get stuck, creating a dilemma. For trapped personnel: Traditional oxygen supply methods involve lowering the oxygen supply device into the well, which can easily slip and injure the trapped person's head during descent. Furthermore, the confined space may prevent trapped personnel from operating the oxygen supply device, increasing the risk of oxygen deprivation and unconsciousness. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a downhole rescue oxygen supply device that can achieve safe and efficient downhole rescue oxygen supply, so as to improve downhole rescue efficiency and reduce rescue risks.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An oxygen supply device for downhole rescue includes a carrier vehicle, a storage turntable, and an oxygen supply cylinder. A pressure reducer for reducing oxygen pressure is installed on the top of the oxygen supply cylinder. A valve for releasing oxygen is installed on the top of the pressure reducer, and a pressure gauge for reading oxygen pressure is installed on one side of the pressure reducer. An oxygen delivery pipe is provided on the other side of the pressure reducer. A bearing is installed on the upper surface of the carrier vehicle. A turntable shaft is installed through the center of the storage turntable, which is placed on the upper surface of the bearing. The bearing allows for flexible rotation of the storage turntable. The bottom end of the turntable shaft passes through the center of the bearing, and a handle for driving its rotation is welded to the top of the turntable shaft.

[0008] Furthermore, a tube winding rod is welded to the upper surface of the storage turntable, and an oxygen delivery tube is wound around the outside of the tube winding rod. The front end of the oxygen delivery tube is used to connect to the gas cylinder tube to deliver oxygen, and the oxygen delivery tube is composed of multiple short hoses spliced ​​end to end. The length of the oxygen delivery tube composed of the short hoses spliced ​​end to end is adjustable and easy to replace.

[0009] Furthermore, a vehicle pusher is welded to one end of the upper surface of the vehicle, and a breathing mask storage box is fixed to one side of the vehicle pusher.

[0010] Furthermore, the breathing mask storage box is used to store breathing masks, which are installed at the end of the oxygen delivery tube and worn on the face of the person being rescued to supply oxygen.

[0011] Furthermore, a gas cylinder limiting box is welded to the upper surface of the carrier vehicle. The gas cylinder limiting box is used to store oxygen supply cylinders, and a soft pad is adhered to the inside of the gas cylinder limiting box.

[0012] Furthermore, the bottom of the carrier is equipped with casters.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model, through its structural design of a carrying vehicle, a storage turntable, and an oxygen supply cylinder, solves the problems of complex operation and low rescue efficiency in existing rescue oxygen supply devices. The carrying vehicle design enables the overall device to be portable and mobile, and the omnidirectional wheels at the bottom provide excellent adaptability and flexibility. The cylinder limiting box not only fixes the position of the oxygen supply cylinder but also enhances its protection through a soft padding design, effectively improving the safety of the device.

[0014] The integrated design of the pressure reducer, valves, and pressure gauges ensures a stable and controllable oxygen supply process. The pressure reducer reduces the oxygen pressure to prevent injury to trapped personnel due to excessive pressure; the valves provide flexible flow regulation to ensure accurate oxygen delivery; and the pressure gauges monitor oxygen pressure in real time, allowing rescuers to adjust the pressure according to the actual situation, thereby improving the safety and reliability of the rescue operation.

[0015] The combined design of the storage turntable and the tube winding rod solves the problem of unsmooth oxygen delivery tube deployment. The storage turntable rotates flexibly via bearings, making the release of the oxygen delivery tube more stable; the distribution structure of the tube winding rod ensures that the oxygen delivery tube will not tangle or become blocked during winding and deployment. The oxygen delivery tube is composed of short flexible hoses spliced ​​together, and its length is adjustable. This design makes the device highly adaptable to downhole rescue environments at different depths, and in case of local damage, the corresponding short flexible hose can be replaced, thus improving the overall service life.

[0016] The design of the breathing mask storage box and the breathing masks solves the problems of improper storage and inconvenience in using traditional breathing equipment. The breathing mask storage box uses a partition design to prevent cross-contamination of breathing masks and ensure the hygiene of the rescue equipment.

[0017] The existing device only requires rescuers to wear masks, effectively increasing the operating space for underground rescue, greatly improving their own safety and the success rate of rescue. The existing device can be easily and quickly lowered to the bottom of the well, and the trapped personnel can wear breathing masks themselves. Rescuers can also directly release oxygen, reducing the chance of oxygen deficiency for the trapped personnel and extending the rescue time. Attached Figure Description
