Description
Technical Field
The invention belongs to the technical field of fire-fighting equipment, and particularly relates to a remote fire extinguishing device.
Background
The fire refers to the damage to the surrounding environment caused by the combustion of fire which is out of control in time or space, and the fire causes great loss to the safety of personnel and property, so that the realization of quick fire extinguishing is important in order to reduce the loss and assist the fire safety. But there are many unsatisfactory places in the current fire fighting link; for example, fire-fighting accidents in communities have the problems of dense population, narrow roads and more obstacles, and when fire-fighting vehicles need to perform fire-fighting tasks, the normal passing of the fire-fighting vehicles is affected, so that the gold rescue time is delayed, especially in old communities with long construction time, the infrastructure construction is incomplete, the congestion condition of the internal roads is obvious, and the fire extinguishing of buildings in the communities has the problem of larger casualties caused by the fact that the fire cannot be quickly extinguished; if a fire is put into a fire spot for fire extinguishing due to the complex forest field situation and the complex fire situation after the occurrence of a forest fire, the fire loss is often expanded and the result is more painful due to the fact that the fire fighters lack specific understanding of strange environment and often have more uncertain unsafe factors when entering the fire. Under the above circumstances, a long-distance fire extinguishing launcher is needed to realize fire extinguishing operation, most of the existing long-distance fire extinguishers adopt a fire extinguishing bomb launching cylinder form, the fire extinguishing bomb launching cylinder can launch fire extinguishing bombs to a specified fire extinguishing area, and under the above complex conditions, long-distance and quick fire extinguishing is realized, and casualties are reduced; for example, under the condition of the forest fire, the aim of 'getting early and getting small' in forest fire extinguishment is fulfilled by launching the fire extinguishing bomb at a fixed point and accurately aiming at a fire area through the fire extinguishing bomb launching cylinder so as to effectively control the spreading trend of the forest fire. Most of the existing fire extinguishing bomb launching cylinders rapidly release a bearing body carrying fire extinguishing bombs, so that the bearing body is accelerated to a certain speed to launch the fire extinguishing bombs.
The chinese patent document, also lacking the relevant technical information about the above fire extinguishing launcher, with the publication number CN216439864U, discloses a "fire extinguishing bomb launching device", which comprises a fire extinguishing bomb accommodating mechanism and a launching mechanism connected with each other, wherein the fire extinguishing bomb accommodating mechanism comprises a fire extinguishing bomb accommodating seat and a push plate, and when the fire extinguishing bomb is in a state to be launched, the fire extinguishing bomb is located in the fire extinguishing bomb accommodating seat; the launching mechanism comprises a launching mechanism accommodating seat, a launching spring lock hook, a transmission lock hook supporting piece, a transmission warping plate supporting piece, a cam transmission shaft and a steering engine, and the launching mechanism causes the pushing plate to launch the fire extinguishing bomb through the transmission of mechanical parts in the launching mechanism; although the fire extinguishing bomb launching mechanism has the advantages of simple process, safety, reliability and easily controlled landing point range, the internal components are multiple and complex to assemble, and meanwhile, the firing spring is enabled to impact a push plate at the bottom of the fire extinguishing bomb accommodating mechanism and cause the fire extinguishing bomb launching mode to fail to realize the launching of larger loads and fail to meet the use requirement of high strength; if the publication number is CN201618340U, a portable fire extinguishing bomb pulse air pressure launching device is introduced, which comprises an air storage cylinder and a launcher connected with the air storage cylinder through an air pipe, wherein the launcher comprises an air storage cylinder, a release valve, a launching cylinder and a trigger mechanism controllably communicated with the air storage cylinder, the release valve is arranged between the air storage cylinder and the launching cylinder, and the trigger mechanism controls the opening and closing of the release valve through high-pressure air in the air storage cylinder; it has that the range is farther, the structure is simpler, the security performance is higher, operate a great deal of benefit more simple and convenient, along with the decline of gas receiver pressure, transmission mouth kinetic energy generally can not keep invariable after long-time, can't realize in the short time lasting stable high-speed repeatability transmission energy consumption great, leads to the preparation time overlength, the transmission cycle is long to the emission cost is high, can not reuse the transmission kinetic energy. The existing fire extinguishing bomb launching device can also launch a fire extinguishing bomb in a gunpowder propelling mode, the launching load is large, the distance is long, but the fire extinguishing bomb is expensive and needs extremely harsh storage conditions due to the gunpowder propelling mode, the safety of the fire extinguishing bomb cannot be effectively guaranteed in the launching process, and meanwhile, the existing fire extinguishing bomb launching device also has the defects that the fire extinguishing bomb is high in self using and maintaining cost and can be mastered and used only by long-time training.
