Description

Technical Field

[0001] The utility model relates to the technical field of forest fire prevention, in particular to an intrinsically safe mixing device for forest fire prevention foam quick-setting solidification materials. Background Art

[0002] Since forest fires are highly concealed and difficult to detect, and it takes a long time for personnel to arrive at the fire scene, by the time they are detected and handled, the fire area is already too large and the fire situation is serious. Conventional firefighting tools and personnel find it difficult to quickly and effectively control the fire scene, affecting the timeliness of fire handling. Therefore, when a forest fire occurs, the selection and use of efficient fire-fighting materials and devices can greatly reduce casualties and property losses. However, existing fire-fighting equipment is usually disposable and needs to be sent back to the origin by drone after use. Therefore, its effect on large-scale forest fires is very limited. The fire-fighting devices in the prior art do not have the function of producing fire-fighting foam.

[0003] It is known that a cluster drone forest fire extinguishing method (publication number CN202110764847.7) is now disclosed. This cluster drone forest fire extinguishing method establishes a drone collaborative fire extinguishing path planning neural network, establishes a correspondence between forest fire intelligence parameters and drone cluster fire extinguishing path planning, obtains the plan and implements fire extinguishing operations. However, although the above technical solution can play a certain role in fire extinguishing.

[0004] At present, the existing fire-fighting equipment is usually disposable and needs to be sent back to the origin by drone after use, so its effect on large-scale forest fires is very limited. The device is not equipped with relevant fire-fighting equipment foam production structure, which makes it difficult to fully utilize the fire-extinguishing agent and the drone's fixed-point and directional rapid and effective fire extinguishing. For this reason, we provide an intrinsically safe mixing device for forest fire-retardant foam rapid-setting materials. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an intrinsically safe mixing device for forest fire prevention foam rapid-setting materials, which solves the problem that the device does not have a relevant fire extinguishing equipment foam production structure, which makes it difficult to fully utilize the fire extinguishing agent and the fixed-point and directional rapid and effective fire extinguishing of drones.

[0009] Preferably, a plurality of support seats are symmetrically distributed on two opposite sides of the lower end of the production cylinder, a fixing plate is disposed outside the plurality of support seats, and a pulley is disposed inside the fixing plate.

[0010] The working principle and beneficial effects of the utility model are:

[0011] The utility model transports the quick-setting foam fire extinguishing material inside the temporary storage pipe into the interior of the temporary storage pipe through the feeding pipe, and then starts the motor 2 to rotate. The motor 2 drives the spiral blade to rotate during the rotation process. The spiral blade moves the quick-setting foam fire extinguishing material on one side of the temporary storage pipe toward one end of the motor 2 during the rotation process. The quick-setting foam fire extinguishing material inside the temporary storage pipe falls into the interior of the production tube from the discharge port during the movement toward the one end of the motor 2, and then starts the air pump A to make it work. During the operation of the air pump A, external air is sucked into the interior of the production tube through the air inlet pipe, and then starts the motor 1 to rotate. The motor 1 drives the rotation of the rotating rod during the rotation process. The rotating rod drives the rotation of the stirring member during the rotation process. The stirring member fully stirs the quick-setting foam fire extinguishing material and air inside the production tube to generate foam, and the generated foam is sprayed out from the foam outlet, so as to continuously generate fire extinguishing foam and effectively extinguish fire.
