Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a combined water retaining device for assisting fire-fighting. Background Art

[0002] During ground fire fighting, the water sprayed by the fire trucks tends to flow along the ground. For example, when a car catches fire, firefighters spray water on the car to put out the fire. However, after the water contacts the burning car, it flows to the ground and flows along the ground. The water cannot gather around the burning car and cannot cool down the burning car or the road surface, which may cause problems such as the spread of the fire.

[0042] The annular water retaining layer 1 includes a transverse portion 12 and a vertical portion 13. The transverse portion 12 and the vertical portion 13 are an integrated structure.

The connecting piece can be an integrated structure with the seat body.

[0065] The working principle of this embodiment:

[0066] When using the water retaining device, first place the support assembly 2 around the fire source so that the support rod group 21 of the support assembly 2 is evenly distributed around the fire source, and then the water retaining sheet 14 is sequentially sleeved on the support rod group 21.

[0067] Then, the inner zipper 15 and the outer zipper are operated to connect two adjacent water retaining sheets 14 to form a water accumulation chamber 11 .

[0068] After completing the above operations, the fire truck sprays water to the fire source, and the water entering the fire source flows along the ground to the top of the transverse portion 12. As the liquid level in the water accumulation chamber 11 rises, the water in the water accumulation chamber 11 presses the transverse portion 12 against the ground to prevent the water in the water accumulation chamber 11 from leaking. The longitudinal portion is used to block water to prevent the water in the water accumulation chamber 11 from leaking. The water in the water accumulation chamber 11 surrounds the fire source, and the fire is not easy to spread.
