Description
Technical Field
The invention belongs to the technical field of fire-fighting facilities, and particularly relates to a telescopic boom water cannon fire-extinguishing device of an emergency rescue fire-fighting truck.
Background
As known in the industry, if the fire truck chassis bearing capacity is classified according to the fire truck chassis bearing capacity, there are light fire trucks, medium fire trucks and heavy fire trucks, the light fire truck chassis bearing capacity is usually 500-5000Kg, and the light fire truck comprises light foam fire truck, light dry powder fire truck, light communication command truck, light investigation fire truck and the like; the chassis bearing capacity of the medium-sized fire engine is usually 5000-8000Kg, and mainly comprises a medium-sized water tank fire engine, a foam fire engine, a dry powder fire engine, an equipment fire engine, a communication command fire engine and the like; the chassis bearing capacity of the heavy fire truck is more than 8000Kg, and the heavy fire truck mainly comprises a heavy water tank fire truck, a heavy foam fire truck, a heavy dry powder fire truck, a fire truck with combination of heavy foam and dry powder, a heavy ascending platform fire truck, a heavy aerial ladder fire truck and the like.
If the fire-fighting vehicles are classified according to the functions of the fire-fighting vehicles, the fire-fighting vehicles for the airport and the special investigation fire-fighting vehicles, the aforementioned emergency rescue fire-fighting vehicles belong to the category of the special investigation fire-fighting vehicles, and are generally composed of a chassis, a carriage body (various emergency rescue equipment is arranged in the carriage body), a power takeoff, a transmission device, a lighting system and an electrical system, which are common fire-fighting vehicles. Technical information of the rescue fire-fighting truck is visible in the published Chinese patent literature, for example, a carriage passenger car type rescue fire-fighting truck is disclosed in CN2547343Y, a shelter-based rescue fire-fighting truck is proposed in CN206334242U, a bidirectional running rail dual-purpose multifunctional rescue fire-fighting truck is recommended in CN103935285B, a road rescue fire-fighting truck is provided in CN207024442U, a narrow region rescue fire-fighting truck is introduced in CN107933688A, and the like.
As is clear from a reading of patent documents not limited to the above, the prior art rescue and fire truck is not equipped with a water tank, a fire monitor (i.e., the water monitor), a trailer assembly, a telescopic climbing ladder device, and the like, and thus has the following drawbacks: firstly, because in certain rescue and relief occasions, emergency fire extinguishment needs to be carried out from floors at the first time, but because the functions of the rescue and relief fire-fighting vehicles are limited, the fire-fighting vehicles can only play a role by virtue of other fire-extinguishing fire-fighting vehicles with corresponding functions, on the one hand, the fire can not be effectively controlled and even be extinguished at the first time, on the other hand, if the space of the rescue and relief places is limited, the requirements of different functions and different types of fire-fighting vehicles for driving in and parking can not be met, and precious rescue time can be delayed; secondly, the rescue fire truck has monotonous functions, such as the water cannon function, so that the maximum utilization of fire resources is not facilitated, and the resource waste is caused to a great extent; thirdly, the fire-fighting facility cost of the fire department is increased and the rescue cost is correspondingly increased.
