Problems solved by technology

In foreign countries, there are soft air supply pipes specially equipped for temporary air supply in case of fire or poisonous gas in the subway, but there are many hard circles in the pipe with the same diameter as the pipe, which is to prevent the air pipe from collapsing when blowing air. These hard surrounds increase the volume and weight of the hose, making it inconvenient to carry and place the air supply pipe

specific Embodiment approach 2

[0028] Figure 10 It is a wind pocket (4) of another sewing method, and the wind pocket (4) is separated into small pockets one by one by separating sutures (4-5). Each small pocket is not connected to each other, and the small pocket has a wind pocket ( 4-3), a circle of the inner wall of the air duct (1) is made into several small pockets, and correspondingly there are air pockets (4-3). The tube will not collapse. This method is that the wind pocket is relatively strong and can withstand a lot of wind.

specific Embodiment approach 3

[0029] Figure 11 It is another kind of sewing method for the wind pocket (4). There are partition seams (4-5) to separate the wind pockets (4) into small pockets, but the partition seams (4-5) are not sewn to the end, so There are mouths on both sides of the bottom side of each small pocket, so that each small pocket is connected, and each small pocket has a wind pocket (4-3). This method is that the wind pocket (4) will bulge better, and there is Separation seam (4-5) has strengthened wind pocket (4) solid strength, can bear very big wind.

Abstract

Circular hood type soft blast tube is composed of fan, soft blast tube and circular hood etc. In time of air blowing, circular hood is plumped up, and blast tube is supported circularly so as to be good for a expedite flue. The soft blast tube is prepared as following: a round of circular hoods are tailored on inner wall of the blast tube in every distance (about 1.5 M); material of circular hood is same to material of the blast tube; being cutting up into a long strip, cloth of circular hood is tailored on inner wall of the blast tube in transverse direction directly; several holes of circular hood prepared when tailoring circular hood. Cloth of circular hood is in use for front circular hood and back circular hood. After being sewed, the back circular hood is closed, no air going through. It is not sewing on the said holes on front circular hood. Thus, entering through the holes, wind plumps up the soft blast tube.

Description

Technical field [0001] The invention relates to an air supply pipe, in particular to a soft air supply pipe for temporary air supply in subways or tunnels. Background technique [0002] At present, most of the air supply pipes on the market are hard pipes, but if they need to be used temporarily in subways or tunnels, hard pipes are not suitable and the cost is relatively high. In foreign countries, there are soft air supply pipes specially equipped for temporary air supply in case of fire or poisonous gas in the subway, but there are many hard circles in the pipe with the same diameter as the pipe, which is to prevent the air pipe from collapsing when blowing air. These hard surrounds increase the volume and weight of the hose, making it inconvenient to carry and place the air supply pipe. Contents of the invention [0003] According to the shortcomings of the above-mentioned inflatable cushions, the present invention has invented a soft air supply pipe with a wind pocke...
