[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.
[0026] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:
[0027] A coal mine emergency rescue device includes a box body 1. Inside the upper end of the box body 1, an airbag 2 is movably connected. At the upper end of the airbag 2, an exhaust valve 21 and a connecting pipe 22 are fixedly connected. The connecting pipe 22 is located to the right of the exhaust valve 21. At the upper end of the connecting pipe 22, a mouthpiece 23 is fixedly connected. At the front end of the mouthpiece 23, a convex block 231 is fixedly connected. At the upper and lower ends of the convex block 231, guard plates 232 are fixedly connected. Inside and outside the mouthpiece 23, a breathing assembly 3 is jointly arranged. The breathing assembly 3 includes a second swing rod 331 movably connected to the upper end inside the mouthpiece 23, and the number of the second swing rods 331 is two. At the front ends of the two second swing rods 331, nose clips 34 are fixedly connected. The breathing assembly 3 further includes a touch plate 31 movably connected to the rear end of the guard plate 232. At the lower end of the touch plate 31, a spring 311 is fixedly connected. At the rear end of the touch plate 31, a first swing rod 32 is movably connected. At the rear end of the first swing rod 32, a first connecting rod 321 is movably connected. At the front and rear sides of the upper end of the first connecting rod 321, second connecting rods 33 are movably connected. The front ends of the two second connecting rods 33 are respectively fixedly connected to the rear ends of the two second swing rods 331. The airbag 2, the connecting pipe 22, and the convex block 231 are all made of flexible materials. The airbag 2 and its upper components can be all received inside the box body 1. The elastic force of the torsion spring 51 is greater than the resistance of the air delivery pipe 52 on the wire reel 5.
[0028] By adopting the above technical solution, when an accident occurs in a coal mine and the operators need to conduct self-rescue, the box body 1 is hung on the necks of the operators through the shoulder straps 11. The box cover 12 is turned over and opened, and components such as the airbag 2 and the breathing assembly 3 inside the box body 1 are taken out. The operator holds the mouthpiece 23 with the right hand and places it in front of the face. By placing the convex block 231 in the mouth, the mouthpiece 23 blocks the mouth. At the same time, the teeth in the oral cavity bite the position at the rear end of the spring 311 outside the convex block 231. When the teeth bite the touch plate 31, the touch plate 31 moves downward under force. The downward movement of the touch plate 31 pushes the first connecting rod 321 upward through the first swing rod 32. The upward movement of the first connecting rod 321 drives the two second connecting rods 33 to move upward. The upward movement of the two second connecting rods 33 makes the lower ends move closer to each other. Then, through the movement of the second connecting rods 33, the second swing rods 331 are driven to move. The movement of the two second swing rods 331 makes the nose clips 34 at the front ends move closer to each other. The two nose clips 34 move closer to clamp and fix the noses of the operators. At this time, by rotating the control valve 41 to open the oxygen cylinder 4, the oxygen inside the oxygen cylinder 4 continuously enters the airbag 2. Through the continuous breathing of the operator, the oxygen continuously enters the human body from the convex block 231, and the exhaled gas is discharged through the exhaust valve 21. To achieve that when an accident occurs in a coal mine, during the process of oxygen inhalation, the nose clips 34 on the device can automatically clamp, thus avoiding the phenomenon that the nose clips 34 fall off during the emergency rescue process, and further improving the efficiency of the rescue device.
[0029] Specifically, as Figure 4 shown, a strap 11 is movably connected between the left and right ends of the box body 1, a box cover 12 is movably connected to the upper end of the box body 1, an oxygen cylinder 4 is fixedly connected to the left end inside the box body 1, a control valve 41 is movably connected to the upper end of the oxygen cylinder 4, an air pipe 52 is fixedly connected between the oxygen cylinder 4 and the airbag 2, a wire reel 5 and a fixed rod 53 are movably connected to the rear end inside the box body 1, the fixed rod 53 is located at the right end of the wire reel 5, a torsion spring 51 is fixedly connected to the rear part of the wire reel 5, the air pipe 52 is wound inside the wire reel 5, the air pipe 52 penetrates through the fixed rod 53, and a folding sleeve 54 is movably connected to the outside between the upper end of the fixed rod 53 and the air pipe 52. The elastic force of the spring 311 is greater than the sum of the gravity of the touch plate 31 and the first swing rod 32, and the two springs 311 are staggered with each other.
[0030] By adopting the above technical solution, when an accident occurs in a coal mine and the operator needs to perform self-rescue, the box body 1 is suspended around the operator's neck through the strap 11, the box cover 12 is turned over and opened, components such as the airbag 2 and the breathing assembly 3 inside the box body 1 are taken out, the breathing assembly 3 is placed in front of the mouth, and during the movement of the airbag 2, the air pipe 52 outside the wire reel 5 is moved towards the airbag 2. During the movement, the front end of the folding sleeve 54 moves together with the air pipe 52, and the rear end is fixed outside the fixed rod 53, so that the rear end of the air pipe 52 continuously passes through the folding sleeve 54, thereby achieving the purpose of protecting the extended air pipe 52 and preventing it from being bent. During the process of escape and rescue, the air pipe 52 moves continuously, and the movement of the air pipe 52 continuously drives the wire reel 5 to rotate. When the air pipe 52 shortens and returns after extending, the torsion spring 51 drives the wire reel 5 and the external air pipe 52 to always maintain the shortest position, so as to achieve the purpose of keeping the air pipe 52 close to the operator. Thus, when the operator moves during the rescue, the device can be protected and close to the operator, thereby ensuring the quality of the extended pipeline and further avoiding the extended air pipe 52 from hindering the rescue movement.
[0031] Working principle: First, flip open the box cover 12, take out components such as the airbag 2 and the breathing component 3 inside the box body 1. The operator holds the mouthpiece 23 in the right hand and places it in front of the face. By placing the convex block 231 in the mouth, the mouthpiece 23 blocks the mouth. At the same time, the teeth in the oral cavity bite the rear end position of the external spring 311 of the convex block 231. When the teeth bite the touch plate 31, the touch plate 31 is forced to move downward. The downward movement of the touch plate 31 pushes the first connecting rod 321 upward through the first swing rod 32. The upward movement of the first connecting rod 321 drives the two second connecting rods 33 upward. The upward movement of the two second connecting rods 33 causes the lower ends to move closer to each other. Then, the movement of the second connecting rods 33 drives the second swing rods 331 to move. The movement of the two second swing rods 331 causes the nose clips 34 at the front ends to move closer to each other. The two nose clips 34 move closer to each other to clamp and fix the operator's nose. At this time, the oxygen cylinder 4 is opened by rotating the control valve 41. The oxygen inside the oxygen cylinder 4 continuously enters the airbag 2. Through the continuous breathing of the operator, the oxygen continuously enters the human body from the convex block 231, and the exhaled gas is discharged through the exhaust valve 21. To achieve that when an accident occurs in a coal mine, during the process of oxygen inhalation, the nose clips 34 on the device can automatically clamp, thus avoiding the phenomenon that the nose clips 34 fall off during the emergency rescue process, and further improving the efficiency of the rescue device.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
