Description

Technical Field

[0001] The invention belongs to the technical field of fire-fighting facility demonstration devices, and in particular relates to a self-priming foam fire-fighting facility demonstration device. Background Art

[0002] A self-priming foam firefighting system is a portable, lightweight firefighting device that generates and dispenses air-foam liquid. The foam gun head features a gun-shaped handle and a horseshoe-shaped on / off switch, hence the name "double-handled foam firefighting gun." It is used to extinguish fires in small oil tanks, on-ground oil, and oil products. In small oil depots or oil product storage areas, self-priming air-foam guns can be quickly deployed for firefighting. The principle of a self-priming foam firefighting system is to draw in air and mix it with a liquid foam to form fire-extinguishing foam, which is then dispensed to extinguish the fire. This type of equipment provides flexibility in firefighting operations, allowing firefighters to quickly move and adjust the spray angle to suit the fire scene.

[0003] When conducting a self-priming foam fire-fighting facility operation demonstration, the existing fire-fighting facilities are large in size and mass, which is not conducive to demonstration use in the demonstration area.

The adjacent ends of the water tank 2 and the foam liquid tank 3 are both pasted with rubber pads, and a rubber pad is also provided between the outer top surface of the water tank 2 and the placement board 13.

[0032] A foam gun head 4 is movably connected to the demonstration box 1 in the area above the placement plate 13 through a connecting mechanism 5. A demonstration window 14 for demonstrating the foam gun head 4 is provided at the top of the demonstration box 1. The water receiving end 41 of the foam gun head 4 is connected with the water tank 2 through a water pipe, and the foam liquid end 44 of the foam gun head 4 is connected with the foam liquid tank 3 through a pipeline. A foam spray outlet 45 is provided at the front end of the foam gun head 4. Through the coordinated use of the water tank 2, the foam liquid tank 3 and the foam gun head 4, the demonstration of the self-priming foam fire fighting process can be completed, which is convenient and practical for intuitively demonstrating the principle and process of self-priming foam fire fighting.

[0033] There are two sliding door panels 11, and the top and bottom ends of the opening side of the demonstration box 1 are both provided with slide grooves. The top and bottom ends of the sliding door panels 11 are both provided with sliders, and the sliders are slidably connected in the slide grooves. The water or foam liquid in the demonstration box 1 can be replenished through the sliding door panels 11, and the installation and operation process of the foam gun head 4 can also be carried out in an open manner, which is convenient for improving the efficiency of equipment assembly.

[0034] A transparent observation window is provided in the middle of the sliding door panels 11, and locking blocks are provided at the adjacent ends of the two sliding door panels 11. The locking blocks are used to complete the fixed connection between the two sliding door panels 11. The collaborative operation process of water and foam liquid can be intuitively understood through the transparent observation window.

The connecting seat 51 can also be fixedly connected to the connecting shaft 52 by a fixing rod 53 clamped on the demonstration box 1, so that the direction of the connecting seat 51 can be adjusted. That is, when performing a fire demonstration, the foam gun head 4 can be taken out and the direction of the connecting seat 51 can be adjusted to the following direction: Figure 1 In the manner shown, after the demonstration is completed, the foam gun head 4 is placed inside the demonstration box 1, and the direction of the connecting seat 51 is adjusted to the direction shown in FIG.

When the foam gun head 4 is folded up, the foam gun head 4 is stuck in the placement seat 131, thereby preventing the foam gun head 4 from shaking when not in use and preventing the foam gun head 4 from being accidentally damaged.

[0042] In order to improve the stability of the connection between the water tank 2 and the foam liquid tank 3 and the foam gun head 4, the water pipes connecting the foam gun head 4 and the water tank 2 and the pipes connecting the foam liquid tank 3 are all flexible transparent plastic pipes, and the transparent plastic pipes are conducive to observing the combination of water and foam liquid, which is convenient and practical.
