Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically a long-tube air breathing apparatus. Background Technology

[0002] Air respirators are equipment used in tunnel construction. During tunnel construction, as the tunnel deepens, the oxygen level inside decreases. Air respirators deliver oxygen into the tunnel to supply the workers, ensuring normal construction and safety. However, they still have the following drawbacks:

[0003] As tunnels become deeper, the oxygen levels inside decrease, and the existing oxygen supply pipes for breathing apparatus are too short to conveniently supply oxygen to deeper tunnels. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a long-tube air respirator, which effectively solves the problem that the oxygen supply pipe of the existing air respirator is too short and inconvenient to supply oxygen to deep tunnels.

[0010] Preferably, a movable block is movably installed inside the movable groove. The outer wall of the movable block is in close contact with the inner wall of the movable groove. A first spring is installed on the side of the movable block near the vertical plate. A first connecting groove is opened on the side of the movable block near the vertical plate. A second connecting groove is opened at equal angles inside the movable block. The second connecting groove is L-shaped. One end of the second connecting groove is connected to the first connecting groove. The other end of the second connecting groove extends to the side of the movable block away from the vertical plate. One end of the movable block contacts the end of the movable groove away from the vertical plate. One end of the second connecting groove is closed.

[0011] Preferably, the oxygen cylinder is equipped with a connecting hose, and a connector is installed at the end of the connecting hose.

[0026] Example 1, by Figure 1-5 As shown, this utility model relates to a long-tube air respirator, including a trailer 1, with an oxygen outlet assembly 2 installed at the top of the trailer 1;

[0027] The oxygen outlet assembly 2 includes a base 201 mounted on the top of the trailer 1. A vertical plate 202 is fixedly mounted on the top of the base 201. Two oxygen cylinders 203 are placed on both sides of the vertical plate 202. An air chamber 205 is opened inside the vertical plate 202. One end of the air chamber 205 is connected to an external pipe 207. A pressure gauge 208 is mounted on the external pipe 207. Connectors 206 are symmetrically mounted on both sides of the vertical plate 202, and each connector 206 corresponds to one oxygen cylinder 203. A coil 3 is mounted on the top of the trailer 1, and an air tube 4 is wound on the coil 3. One end of the trachea 4 is connected to the external tube 207. Straps 204 are symmetrically installed on both sides of the vertical plate 202. The straps 204 are used to fix the oxygen cylinder 203. The oxygen cylinder 203 is connected to the air chamber 205. One end of the trachea 4 is connected to the external tube 207, so that the oxygen in the oxygen cylinder 203 can be discharged from one end of the trachea 4. The trachea 4 is relatively long and is wrapped around the outside of the coil 3, which makes it easy to store the trachea 4 and to bring one end of the trachea 4 into a deeper tunnel for use, so as to facilitate oxygen replenishment in tunnels of different depths.

[0028] The connector 206 includes connecting pipes 2061 symmetrically installed on both sides of the vertical plate 202. Each connecting pipe 2061 has symmetrically formed slots 2062 on both sides. A movable groove 2063 is formed inside the connecting pipe 2061. End grooves 2064 are symmetrically formed at both ends of the movable groove 2063. The inner diameter of the movable groove 2063 is larger than the inner diameter of the end groove 2064. One end groove 2064 communicates with the air chamber 205, while the other end groove 2064 extends to the outside of the connecting pipe 2061. A movable block 2065 is movably installed inside the movable groove 2063. The outer wall of the movable block 2065 is in close contact with the inner wall of the movable groove 2063. A first spring 2066 is installed on the side of block 2065 near the vertical plate 202. A first connecting groove 2067 is formed on the side of movable block 2065 near the vertical plate 202. A second connecting groove 2068 is formed at equal angles inside movable block 2065. The second connecting groove 2068 is L-shaped. One end of the second connecting groove 2068 is connected to the first connecting groove 2067, and the other end of the second connecting groove 2068 extends to the side of movable block 2065 away from the vertical plate 202. One end of movable block 2065 contacts the end of movable groove 2063 away from the vertical plate 202. One end of the second connecting groove 2068 is closed. A connecting spring is installed on oxygen cylinder 203. A connecting hose 209 is provided, and a connector 210 is installed at the end of the connecting hose 209. The connector 210 includes a connecting sleeve 2101 fixedly installed at the end of the connecting hose 209. The inner diameter of the connecting sleeve 2101 is the same as the outer diameter of the connecting pipe 2061. A push rod 2102 is installed inside the connecting sleeve 2101. Side cylinders 2103 are symmetrically installed on both sides of the connecting sleeve 2101. A locking rod 2104 is movably installed inside the side cylinder 2103. One end of the locking rod 2104 is located inside the connecting sleeve 2101, and a second spring 2105 is installed at the other end of the locking rod 2104. One end of the second spring 2105 is located away from the connecting sleeve 2101 on the side cylinder 2103. One end of the inner wall is fixedly connected, and the other end of the lever 2104 is equipped with a pull rod 2106. The end of the pull rod 2106 extends through to the outside of the side cylinder 2103. When the oxygen cylinder 203 is connected to the gas chamber 205, the connecting sleeve 2101 is installed on the outside of the connecting pipe 2061, so that the push rod 2102 can push the movable block 2065 to move towards the vertical plate 202, opening one end of the second connecting groove 2068, so that the oxygen in the oxygen cylinder 203 can enter the gas chamber 205. When the number of oxygen cylinders 203 is small, one end of the second connecting groove 2068 on the movable block 2065 in the unconnected connecting pipe 2061 is closed to prevent air leakage and facilitate use.

[0029] Working principle: During operation, two oxygen cylinders 203 are first placed on both sides of the vertical plate 202. The oxygen cylinders 203 are then secured with straps 204. The pull rods 2106 on both sides of the connecting sleeve 2101 at the end of the connecting hose 209 on the oxygen cylinder 203 are pulled outward, causing the locking rod 2104 to enter the side cylinder 2103. The connecting sleeve 2101 is then fitted onto the outside of the connecting pipe 2061, and the locking rod 2104 is then engaged in the slot 2062, thus securing the connecting sleeve 2101. During the installation of the connecting sleeve 2101... The push rod 2102 pushes the movable block 2065 toward the vertical plate 202, thereby opening the second connecting groove 2068; then the valve on the oxygen cylinder 203 is opened, allowing oxygen in the oxygen cylinder 203 to enter the oxygen cylinder 203. At the same time, when using, the number of oxygen cylinders 203 does not need to be set to four. When the number of oxygen cylinders 203 is small, some of the connecting pipes 2061 are not used. At this time, the second connecting groove 2068 on the movable block 2065 is closed, so that the oxygen entering the gas chamber 205 will not leak.

[0030] When in use, the trailer 1 is towed to the outside of the tunnel. Since the air pipe 4 is wrapped around the outside of the coil 3, the construction workers bring one end of the air pipe 4 into the tunnel. Because the air pipe 4 is relatively long, it is convenient to replenish oxygen in tunnels of different depths. After one end of the air pipe 4 is brought into the tunnel, the pressure gauge 208 is turned on so that the oxygen in the oxygen cylinder 203 can be sent into the tunnel through the air pipe 4. The exhaust speed can be controlled by the pressure gauge 208.
