Description

Backpack damping type movable fire extinguishing device Technical Field The utility model relates to a fire extinguishing device, in particular to a backpack damping type mobile fire extinguishing device, and belongs to the technical field of fire extinguishing. Background In complex scenes such as high-rise building fires, mountain forest fires and the like, firefighters need to bear a fire extinguishing device to perform quick motorized fire extinguishing. The traditional backpack type movable fire extinguishing device takes a rigid backpack frame as a core, a fire extinguisher main body is fixed through a metal or engineering plastic frame, and a foundation backpack function is realized by matching nylon shoulder straps and waistbands. The technology focuses on mechanical shock absorption and pneumatic driving, namely, a slide rail-slide bolt sliding structure or an elastic suspension rope is adopted to absorb vertical impact, and the compressed gas cylinder is used for driving the fire extinguishing agent to spray. In specific implementation, the backpack frame is matched with the sliding bolt through the sliding rail groove to realize up-and-down buffering of the fire extinguisher. The liquid storage tank is hung on the open back frame through four-corner elastic ropes, and shake is counteracted by utilizing rubber deformation. Specifically, when a firefighter performs a rapid motorized fire extinguishing task, the conventional backpack fire extinguishing device has the following technical defects: (1) The lack of an effective shock-absorbing structure aggravates the burden on the human body. The existing backpack fire extinguishing device is not provided with a special damping system, and a fire extinguisher and the back of a human body form rigid contact in the running and climbing process of a fire fighter. External impact force is directly transmitted to the shoulder and the waist through the back frame, and especially when crossing obstacles or emergency braking, longitudinal and transverse compound vibration is overlapped, so that the muscle load is obviously increased, and chronic sports injury is easily caused during long-term operation. (2) In addition, the water tank of the existing knapsack fire-extinguishing device has no anti-shaking structure, and liquid inertia impact is serious. The traditional water tank adopts a single cavity design, and when the fire extinguishing agent (such as water and foam solution) is not fully loaded, the liquid can generate intense sloshing due to inertia in the maneuvering process. The gravity center of the device is frequently deviated, so that firefighters are forced to consume additional physical power to maintain balance, and the fluctuation of the spraying pressure of the extinguishing agent is more likely to be caused, and the stability of the extinguishing jet flow is affected. In the prior art, the actual use efficiency of the backpack fire extinguishing device is seriously restricted due to the lack of shock absorption and insufficient liquid sloshing control. Disclosure of utility model In view of the above, the present utility model provides a backpack shock-absorbing mobile fire extinguishing device, which can solve the above technical problems. The technical scheme of the utility model is that the backpack damping type movable fire extinguishing device comprises a fixed plate, a pressing plate, a damper and a water tank; the water tank is in sliding fit with the fixed plate, and can slide up and down relative to the fixed plate; The shock absorber is vertically arranged on the shock absorber fixing seat, and the shock absorber fixing seat is arranged on the fixing plate; The pressure plate is mounted on the water tank and is located above the shock absorber, and the pressure plate can be in contact with the shock absorber when moving downwards along with the water tank. As a preferable mode of the utility model, a plurality of partition boards are arranged in the water tank at intervals along the height direction and used for separating the internal space of the water tank, and a plurality of water permeable holes are distributed on the partition boards. As a preferable mode of the utility model, the guide rail is arranged on the fixed plate, the back surface of the water tank is provided with the sliding block which is in sliding fit with the guide rail, and the sliding block can slide up and down in the guide rail. As a preferable mode of the present utility model, the fixing plate is a carbon fiber plate. As a preferable mode of the utility model, the damper is a hydraulic damper. In a preferred mode of the utility model, the fixing plate is provided with a reserved interface for being connected with the shoulder strap. The damper is arranged at the middle position of the back of the water tank in the width direction, the two sliding blocks are symmetrically arranged at the left side and the right side of the damper, the pressing plate is a tr
