Weikong warp-spray reciprocating full-area columnar water jet fire extinguishing device and its application

Abstract

The invention belongs to the fire-fighting field and particularly provides a latitude-control longitude-spraying reciprocating global columnar water-jetting fire-extinguishing device. The latitude-control longitude-spraying reciprocating global columnar water-jetting fire-extinguishing device is mainly composed of a water delivery pipe, a transmission mechanism, a latitude rotating cylinder, a longitude rotating cylinder and a transmission rod. The longitude rotating cylinder and the latitude rotating cylinder are rotatably connected in a mutually controlled mode. The transmission rod is located inside the longitude rotating cylinder and the latitude rotating cylinder, and the two ends of the transmission rod are connected with the longitude rotating cylinder and the latitude rotating cylinder respectively. The water delivery pipe is in transmission connection with the transmission rod through the transmission mechanism. The latitude-control longitude-spraying reciprocating global columnar water-jetting fire-extinguishing device has the beneficial effects that the longitude rotating cylinder is driven by recoil force at a water outlet to rotate in the longitude direction, then the transmission mechanism and the fixed water delivery pipe are matched to drive the transmission rod to turn in the latitude direction and the longitude direction, then the longitude rotating cylinder and the latitude rotating cylinder are driven to rotate in the latitude direction together, and thus an automatic reciprocating global jetting effect is achieved. According to the latitude-control longitude-spraying reciprocating global columnar water-jetting fire-extinguishing device, the jetting distance is long, the fire extinguishing area is wide, jetting is conducted outwards from a central point for fire extinguishing, no dead corner exists, and the jetting intensity is high. Meanwhile, the invention provides the application of the latitude-control longitude-spraying reciprocating global columnar water-jetting fire-extinguishing device in the fire-fighting field.

Description

technical field [0001] The invention belongs to the field of fire protection, and in particular relates to a reciprocating all-area columnar water jet fire extinguishing device and its application. Background technique [0002] Fire occurs along with human production and life, causing damage to human life, destruction of human property and wealth, and a huge threat to the lives of firefighters. The vast majority of fires occur in buildings such as factories, warehouses, shopping malls, office buildings, residences and ship cabins where humans work and live. Water is the most widely used extinguishing medium when conventional fires occur. The existing pre-fire extinguishing sprinklers have a small spray range and low intensity. Although the fire extinguishing nozzle has a large amount of water sprayed, a long spray distance, and sufficient spray kinetic energy, it needs to be controlled by firefighters at close range. It sprays into the building through the building gaps su...

AI Technical Summary

Problems solved by technology

Existing pre-extinguishing sprinklers have a small spray range and low intensity

Although the fire extinguishing nozzle has a large amount of water sprayed, a long spray distance, and sufficient spray kinetic energy, it needs to be controlled by firefighters at close range. It sprays into the building through the building gaps such as doors and windows. If the firefighters approach the dead corner to put out the fire at a closer distance, it will cause greater casualties and serious injuries to the firefighters.

Electrically driven fire sprinklers and computer-controlled fire sprinklers, including the power lines that supply power to these devices, themselves cannot avoid being damaged by fire. It is inevitable that these devices will be damaged in high-intensity fires.

[0003] At the same time, there are multiple fire points after the fire scene has diffused. When firefighters enter the scene for rescue, they often can only spray fire extinguishing agent in one direction in front of them to reduce the fire. The fire points on both sides cannot effectively kill and block the effect, which also brings a very large safety hazard to the firefighters' on-site rescue

[0004] To sum up, the fire extinguishing sprinkler devices in the prior art can only spray in a fixed direction, or only multi-domain spray in this direction, the fire extinguishing range is small and there are fire extinguishing dead angles, and it is easy to increase the safety hazard of firefighters
