[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: To address the problem that existing technologies lack effective air purification and oxygen supply systems, making it impossible to maintain good air quality in enclosed spaces and increasing the difficulty of rescue operations, please refer to... Figures 1-8This utility model provides a technical solution: a mobile rescue transition station for mines, including a rescue station 1 and a rescue bed 2 set inside the rescue station 1. A drainage pipe 7 is fixedly connected to the bottom of the back of the rescue station 1. A baffle 4 is installed on the inner wall of the rescue station 1. A ventilation pipe 6 is fixedly installed on the top of the back of the rescue station 1. An air exchange device is set inside the ventilation pipe 6. The air exchange device includes a ventilation mechanism and a purification mechanism.

[0027] The ventilation mechanism includes a filter 601, a mounting ring 607, a mounting bracket 608, a negative pressure fan 609, and a rotating plate 610. The filter 601 is connected to the back of the ventilation duct 6, the mounting ring 607 is fixedly installed on the front of the ventilation duct 6, the mounting bracket 608 is fixedly installed on the front of the mounting ring 607, the negative pressure fan 609 is fixedly installed on the center of the front of the mounting bracket 608, and the rotating plate 610 is connected to the outer surface of the shaft of the negative pressure fan 609. The model of the negative pressure fan 609 is FBDNo6.3 / 2x18.5KW. The filter 601 can filter out dust from the outside air and prevent dust from entering the ventilation duct 6 and causing blockage.

[0028] The purification mechanism includes a packing box 612 and packing material 613. The packing box 612 is slidably connected to the inner wall of the ventilation duct 6 and is made of iron. The packing material 613 is located inside the packing box 612 and consists of three layers: a honeycomb-shaped coconut shell activated carbon adsorption layer, an impregnated activated carbon and metal oxide composite packing adsorption layer, and a composite felt made of glass fiber and polyester fiber. The glass fiber and polyester fiber are mixed in a 3:2 ratio to form the composite felt, and the glass fiber diameter is approximately 5-8 μm. The honeycomb-shaped coconut shell activated carbon adsorption layer uses honeycomb-shaped coconut shell activated carbon as the main adsorption material, with a specific surface area of ​​1200-1500 m². 2 / g, with abundant microporous structure, mainly with pore sizes concentrated in the 1-2nm range, and mesoporous structure with pore sizes in the 2-50nm range. Coconut shell activated carbon has excellent adsorption performance for common harmful gases in mines, such as carbon monoxide, hydrogen sulfide, and sulfur dioxide, and can also remove odors. The honeycomb structure design gives the activated carbon low air resistance, ensuring smooth airflow and facilitating replacement and maintenance.

[0029] The impregnated activated carbon and metal oxide composite filler adsorption layer is based on coconut shell activated carbon, with potassium permanganate, copper oxide, and other chemical reagents loaded through an impregnation process to form a chemical adsorbent. Potassium permanganate can oxidize carbon monoxide to carbon dioxide, and copper oxide can react with hydrogen sulfide to form copper sulfide precipitate, thereby further removing harmful gases. In addition, a small amount of manganese dioxide is added as a catalyst to accelerate the redox reaction rate and improve the purification capacity for low-concentration harmful gases.

[0030] The top and bottom of the front of the rescue station 1 are fixedly connected to a smooth door guide rail 3. A fixing magnet 301 is fixedly connected to the right side of the smooth door guide rail 3. A light-blocking door 302 is slidably connected inside the smooth door guide rail 3. The light-blocking door 302 is made of 6061-T6 aluminum alloy and has an iron shell on its right end. A limit plate 303 is fixedly connected to the left side of the light-blocking door 302. A sealing plate 304 is fixedly connected to the back of the light-blocking door 302. The sealing plate 304 is made of wood and has rubber sealing strips at both ends. When the light-blocking door 302 is pushed to the rightmost side, the light-blocking door 302 will be attracted and fixed by the fixing magnet 301.

[0031] The bottom of the rescue station 1 is fixedly connected to a base 5, the bottom of the base 5 is slidably connected to a slide rail 501, the bottom of the slide rail 501 is fixedly connected to a reinforcing rib 502, the bottom of the reinforcing rib 502 is fixedly connected to a load-bearing plate 503, the bottom of the load-bearing plate 503 is fixedly connected to a caster wheel 504, and the front of the base 5 is fixedly connected to a limit strip 505, which can prevent the rescue station 1 from being pulled out.

[0032] When using the rescue station 1, by pushing the rescue station 1, the base 5 is moved to slide on the surface of the slide rail 501, so that the rescue station 1 can be equipped with reinforcing ribs 502, load-bearing plates 503 and casters 504, which makes the rescue station 1 easy to move.

[0033] Example 2: In actual use, in order to improve the filtration effect when air enters the life-saving station 1, this application fixes buffer spring 1 603 and buffer spring 2 605 to the front and back of the stuffing box 612, and fixes elastic sheet 1 604 and elastic sheet 2 606 to the inner wall of the ventilation pipe 6. The ends of buffer spring 1 603 and buffer spring 2 605 away from the stuffing box 612 are fixedly connected to elastic sheet 1 604 and elastic sheet 2 606 respectively. A sliding pipe 602 is fixedly installed on the back of the rescue station 1. A rotating magnetic block 611 is fixedly connected to the side of the rotating plate 610 near the mounting ring 607. A fixing block 6023 is fixedly connected to the back of the inner wall of the sliding pipe 602. A telescopic spring 6022 is fixedly connected to the front of the fixing block 6023. A magnetic slider 6021 is fixedly connected to the front of the telescopic spring 6022. The magnetic slider 6021 and the side of the rotating magnetic block 611 that are close to each other attract each other. A through hole communicating with the inside of the sliding pipe 602 is opened on the surface of the mounting ring 607. A rotating shaft is connected to the center of the negative pressure fan 609. The rotating shaft is rotatably connected to the center of the mounting bracket 608. The rotating plates 610 are evenly distributed on the outer surface of the rotating shaft.

[0034] As the stuffing box 612 moves continuously, it compresses the buffer springs 603 and 605 on both sides. Under the restriction of the elastic plates 604 and 606, the stuffing box 612 moves within a certain range.

[0035] Working principle: When using the life-saving station 1, the patient is placed on the life-saving bed 2, and then the limiting plate 303 is pushed to drive the light-shielding door 302 to slide inside the smooth door guide rail 3, so that the sealing plate 304 seals the light-shielding door 302 and the life-saving station 1 to prevent outside air and dust from entering. Then, the negative pressure fan 609 is started, allowing outside air to enter through the ventilation pipe 6. After the negative pressure fan 609 is started, its rotating shaft will drive the rotating plate 610 to rotate, and the rotating plate 610 will drive the rotating magnetic block 611 to rotate. When the rotating magnetic block 611 passes through the sliding pipe 602, it will attract the magnetic slider 6021 due to the attraction of the magnetic block 611. The magnetic slider 6021 slides inside the sliding pipe 602. During the sliding process, the magnetic slider 6021 pulls the extension spring 6022 to extend. When the extension spring 6022 is stretched to its maximum extension, it will return to its original position and slide away from the magnetic slider 6021 under the action of its own restoring force. As the rotating magnetic block 611 rotates continuously, the magnetic slider 6021 will slide continuously within a certain distance. Because the stuffing box 612 is made of iron, the magnetic slider 6021 will continuously attract the stuffing box 612 to move during the sliding process, thereby causing the packing 613 to move continuously to purify the incoming air.
