DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See Figure 1-5 A safety emergency device for mines includes an outer cabin 1, an inner cabin 2, and a filling layer 3 filled between the outer cabin 1 and the inner cabin 2. A hatch 4 is rotatably connected to one side of the outer cabin 1. The hatch 4 is provided with a handle 16. A transparent observation window 5 is provided on the upper part of the hatch 4. Several storage cabinets 6 are provided on one side of the inner cabin 2. Food, water and oxygen respirators are provided in the storage cabinets 6. A positioning system 7 and an intercom system 8 are provided on one side of the inner cabin 2. The positioning system 7 belongs to the KJ1570J mine personnel precise positioning system in the prior art. The system is connected to the ground control terminal. An explosion-proof lamp 9 is provided on the top of the inner cabin 2, and the intercom system 8 can be an intercom and a wired communication line and is connected to the control room outside the mine. The outer cabin 1 is connected, and the explosion-proof lamp 9 can make the inner cabin 2 bright to avoid psychological depression of the trapped people. A water supply pipe 10 is connected to one side of the outer cabin 1. When there is no water in the cabin, water can be supplied in time by opening the on-off valve 13. One end of the water supply pipe 10 is connected to the dust-proof water supply pipeline of the mine, and the other end is arranged in the inner cabin 2. A compressed air pipe 11 is provided on the top of the outer cabin 1. One end of the compressed air pipe 11 is connected to the mine compressed air self-rescue system, and the other end is arranged in the inner cabin 2, so that fresh air can be kept in the cabin at any time. A drain pipe 12 is provided on one side of the lower part of the outer cabin 1. One end of the drain pipe 12 is connected to the mine drainage system, and the other end is arranged in the inner cabin 2. The compressed air pipe 11, water supply pipe 10 and drain pipe 12 in the inner cabin 2 are all provided with an on-off valve 13.

[0030] A steel cage-type reinforcement frame 14 is provided between the outer cabin and the inner cabin to enhance the compressive strength of the entire safety emergency device.

[0031] A ventilation device 15 is provided on one side of the upper part of the inner cabin 2, wherein the ventilation device 15 can be an explosion-proof axial flow fan in the prior art, which is intended to extract the exhaust gas from the inner cavity 2. An explosion-proof baffle matching the ventilation device 15 is provided on the wall of the inner cabin 2, wherein the explosion-proof baffle is fixedly arranged on the side wall of the inner cabin 2. This design is to prevent the ventilation device 15 from entering the inner cabin 2 after being squeezed or burst, thereby causing personal injury. The ventilation device 15 can adopt an explosion-proof axial flow fan in the prior art, wherein the dirty air in the cabin discharged by the ventilation device is directly discharged to the temporary refuge chamber.

[0032] There are multiple compressed air bottles placed in the storage cabinet 6. When the compressed air self-rescue system and the underground ventilation system are both destroyed, the spare compressed air bottles can be directly opened to release air to ensure the oxygen required by personnel and the fresh air flow of the mine compressed air self-rescue system and the ventilation system are contaminated (such as when the concentration of toxic and harmful gases such as CO, asphyxiating gases such as CO2, or combustible gases such as CH4 is high), the compressed air bottles can be switched to provide oxygen.

[0033] The oxygen respirator is a HYZ4 isolated positive pressure oxygen respirator, which further ensures the oxygen needs of trapped people.

[0034] The preferred storage cabinet 6 is also provided with several spare oxygen cylinders.

[0035] The lower part of the outer cabin 1 is a cylindrical structure and the top is a hemispherical structure. The outer cabin 1 has a curved surface, which is conducive to pressure relief and timely disperses external forces with high destructive strength such as frontal and top impacts.

[0036] Preferably, the outer cabin 1 is made of high-strength steel, the filling layer 3 is made of polyurethane flame retardant material and aluminum silicate fireproof cotton, and the inner cabin 2 is made of aluminum.

[0037] Rail wheels are connected to two opposite sides of the bottom end of the outer cabin 1, and the arrangement of the rail wheels facilitates the transportation and movement of the device.

[0038] When in use: first, several temporary refuge chambers are designed in the mine tunnel according to the actual situation, and 6-9 safety emergency devices are placed in a temporary refuge chamber to form a refuge unit based on the work team. Several ventilation devices 15 are respectively connected to the ventilation pipes, and the intercom systems 8 are connected to each other through communication lines and connected to the control room outside the mine. When a mine disaster occurs, workers can quickly enter the safety emergency device in the nearest temporary refuge chamber, and then replenish their functions through the water and food stored therein, and contact people outside the mine through the wireless and communication systems of the positioning system to wait for rescue.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be embraced herein, and any reference signs in the claims should not be construed as limiting the claims to which they relate.
