Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting equipment technology, and in particular relates to a solid foam rod. Background Technology

[0002] Existing foam guns use the ejection principle, which introduces a water flow mixed with liquid foam extinguishing agent. A negative pressure is formed around the rapidly ejected fluid, drawing in air from the outside. After one negative pressure air intake and foaming process, the foam extinguishing agent is sprayed out.

[0003] The content of liquid foam extinguishing agent in the mixed solution will affect the final foaming effect of the foam extinguishing agent, but in a fire scene environment, it is not convenient to carry a large amount of liquid foam extinguishing agent.

[0004] This invention relates to a solid foam rod designed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A solid foam rod includes a foam rod with several through-flow channels inside the foam rod, the channels being parallel to the central axis of the foam rod.

[0006] As a preferred embodiment, the foam rod is a cylinder with arc-shaped grooves at both ends.

[0007] As a preferred embodiment, the outer diameter of the foam rod is 40 to 80 mm.

[0008] As a preferred embodiment, the diameter of the flow channel is 5 to 15 mm.

[0009] As a preferred embodiment, the length of the foam rod is 100 to 300 mm.

[0010] Compared with existing technologies, the advantages of this utility model are: 1. The flow channel of this utility model can increase the flow area of ​​the foam rod and adapt to the specific surface area requirements of larger solid foam rods. Therefore, by changing the diameter and number of flow channels, the specific surface area of ​​the foam rod can be adjusted, and the dissolution rate of the foam rod and the mixing ratio of the foam extinguishing agent can be changed, thereby adjusting the final foaming effect of the foam extinguishing agent. It is suitable for different fire extinguishing environment requirements and has the advantage of being easy to carry. Attached Figure Description

[0014] The labels in the diagram are: 1. Foam rod; 2. Flow channel; 3. Groove. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0016] A solid foam rod, such as Figure 1 As shown, it includes a foam rod 1, and several through channels 2 are provided inside the foam rod 1. The channels 2 are parallel to the central axis of the foam rod 1. The foam rod 1 is a cylinder, and arc-shaped grooves 3 are provided at both ends of the foam rod 1.

[0017] Foam rod 1 is made of water-soluble foam extinguishing agent that is solid at room temperature. When in use, foam rod 1 is installed in foam gun. Foam rod 1 dissolves in water to form a solution of a certain proportion. After being foamed by the foaming device of foam gun, the foam extinguishing agent is sprayed out.

[0018] The flow area of ​​foam rod 1 can affect the mixing ratio of foam extinguishing agent, while the flow channel 2 can increase the flow area of ​​foam rod 1, which can meet the specific surface area requirements of larger solid foam rods. Therefore, by changing the diameter and number of flow channels 2, the specific surface area of ​​foam rod 1 can be adjusted, thereby changing the dissolution rate of foam rod 1 and the mixing ratio of foam extinguishing agent, thus adjusting the final foaming effect of foam extinguishing agent. It is suitable for different fire extinguishing environment requirements and has the advantage of being easy to carry.

[0019] The outer diameter of the foam rod 1 is 40 to 80 mm, the diameter of the flow channel 2 is 5 to 15 mm, and the length of the foam rod 1 is 100 to 300 mm.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
