Description

Technical Field

[0001] The utility model relates to the technical field of foam liquid adding devices, in particular to a portable foam liquid adding device for a tunnel. Background Art

[0002] Tunnels are pipes dug by manpower and machinery. Due to the limitations of road conditions, some tunnel disasters are inevitable, one of which is fire. Tunnel fires not only pose a threat to vehicle drivers and passengers, but also make firefighting work difficult for firefighters. Therefore, tunnel firefighting has become one of the important contents of tunnel engineering safety assurance. At present, my country's highway tunnel firefighting equipment generally installs a fire box on the side wall of the tunnel. Fire extinguishers, fire hydrants and water pipes are placed in the box. These equipment can be used on-site in the event of a fire. Foam liquid is stored in the fire-fighting device in the tunnel for fire extinguishing, but the foam also has a shelf life. Expired foam liquid will affect the fire-fighting effect, and staff are required to replace the foam liquid regularly.

[0003] The existing foam liquid adding device has a long pipeline that is not convenient for storage, and the water tanks for holding the foam are of different sizes and cannot be well compatible with water tanks of different sizes. Only one type of water tank can be used, which is very inconvenient; generally, two or more people are required to carry and replace the foam liquid, which is inefficient and requires more manpower and high maintenance cost. Therefore, a portable foam liquid adding device for a tunnel is proposed to address the above problems. Utility Model Content

After the water pipe is wound, the water pipe is inserted into the fixing block on the side where the nozzle of the water pipe is closer to the fixing block, so that the water pipe is stored and fixed. Then the first fixing plate is separated to both sides, the water tank is clamped between the first fixing plates, and the water tanks of different widths are fixed by the spring. After the clamping is completed, The water tank is pressed against the fixed shell in the direction of the fixed rod, and then the handle is held, and the first limiting groove at the corresponding position of the corresponding length of the water tank is selected. The first limiting plate is engaged into the first limiting groove through the handle, and the limiting block is engaged with the outer side of the fixed shell to play a limiting role to prevent the first limiting plate from shaking left and right. The fixing of water tanks of different sizes can be completed by the provided spring and the first fixing plate and the first limiting groove and the first limiting plate, thereby solving the problem that the pipeline of the existing foam liquid adding device is long and inconvenient to store, and the water tanks for holding the foam are also of different sizes, which cannot be well compatible with water tanks of different sizes and can only use one type of water tank, which is very inconvenient.

[0013] 2.
