Description

Technical Field

[0001] This utility model relates to a fire extinguishing device, specifically a backpack shock-absorbing mobile fire extinguishing device, belonging to the field of fire extinguishing technology. Background Technology

[0002] In complex scenarios such as high-rise building fires and mountain forest fires, firefighters need to carry fire extinguishing equipment for rapid mobile firefighting. Traditional backpack-style mobile fire extinguishers are based on a rigid carrying frame, with the fire extinguisher body fixed by a metal or engineering plastic frame, and nylon shoulder straps and a waist belt to achieve basic carrying functionality. Their technology focuses on mechanical shock absorption and pneumatic drive: using a sliding rail-bolt structure or elastic suspension ropes to absorb vertical impact, and using compressed gas cylinders to drive the extinguishing agent spray. In practice, the carrying frame uses sliding rails and bolts to buffer the fire extinguisher's vertical movement. The liquid storage tank is suspended from the open carrying frame by elastic ropes at the four corners, using rubber deformation to counteract swaying.

[0003] Specifically, traditional backpack fire extinguishing devices generally suffer from the following technical defects when firefighters are carrying out rapid mobile firefighting missions:

[0004] (1) Lack of effective shock absorption structure, which increases the burden on the human body. Existing backpack fire extinguishing equipment is not equipped with a dedicated shock absorption system. When firefighters run and climb, the fire extinguisher makes rigid contact with the back of the human body. External impact force is directly transmitted to the shoulders and waist through the back frame. Especially when crossing obstacles or braking in an emergency, the longitudinal and lateral combined vibrations are superimposed, resulting in a significant increase in muscle load. Long-term operation can easily lead to chronic sports injuries.

[0005] (2) In addition, the water tanks of existing backpack fire extinguishing devices lack anti-sway structures, resulting in severe inertial impact of the liquid. Traditional water tanks use a single-chamber design, and when the extinguishing agent (such as water or foam solution) is not fully loaded, the liquid will sway violently due to inertia during movement. This not only causes the device's center of gravity to shift frequently, forcing firefighters to expend extra energy to maintain balance, but may also cause fluctuations in the extinguishing agent spray pressure, affecting the stability of the extinguishing jet.

[0006] Existing technologies suffer from a lack of shock absorption and insufficient control of liquid sloshing, which severely limits the actual effectiveness of backpack fire extinguishing devices. Utility Model Content

[0007] In view of this, the present invention provides a backpack shock-absorbing mobile fire extinguishing device that can solve the above-mentioned technical problems.

[0008] The technical solution of this utility model is: a backpack shock-absorbing mobile fire extinguishing device, comprising: a fixing plate, a pressure plate, a shock absorber, and a water tank;

[0009] The water tank is slidably engaged with the fixed plate, and the water tank can slide up and down relative to the fixed plate;

[0010] The shock absorber is vertically mounted on the shock absorber mounting base, and the shock absorber mounting base is mounted on the mounting plate;

[0011] The pressure plate is installed on the water tank and located above the shock absorber. When the pressure plate moves down with the water tank, it can come into contact with the shock absorber.

[0012] As a preferred embodiment of this utility model: a number of partitions are provided at intervals along the height direction inside the water tank to separate the internal space of the water tank, and a number of water-permeable holes are distributed on the partitions.

[0013] As a preferred embodiment of this utility model: a guide rail is provided on the fixing plate, and a slider is provided on the back of the water tank that slides in cooperation with the guide rail, and the slider can slide up and down within the guide rail.

[0014] As a preferred embodiment of this utility model, the fixing plate is made of carbon fiber plate.

[0015] As a preferred embodiment of this utility model, the shock absorber is a hydraulic shock absorber.

[0016] As a preferred embodiment of this utility model, the fixing plate is provided with a reserved interface for connecting to the shoulder strap.

[0017] In a preferred embodiment of this utility model: the shock absorber is located in the middle of the width direction of the back of the water tank, and two sliders are symmetrically arranged on the left and right sides of the shock absorber; the pressure plate is a horizontally arranged strip plate, and the fasteners for fixing the two sliders pass through both ends of the pressure plate and are fixed to the back of the water tank.

[0018] Beneficial effects:

[0019] (1) In the portable fire extinguishing device with shock absorption of this utility model, the water tank can move up and down relative to the fixed plate, and shock absorbers are set on the movement path to reduce the force transmitted to the firefighter when the firefighter carries the fire extinguishing device for moving operations.

[0020] (2) In the backpack shock-absorbing mobile fire extinguishing device of this utility model, several partitions are arranged at intervals along the height direction inside the water tank. When the water tank is not full of water, the partitions can passively reduce the liquid fluctuation in the water tank caused by the firefighters during the movement, thereby reducing the shear force and inertial force of the liquid on the water tank; at the same time, it reduces the additional force caused by the shift of the center of gravity.

[0021] (3) In the backpack shock-absorbing mobile fire extinguishing device of this utility model, the fixing plate is made of carbon fiber plate, which can significantly reduce the weight of the device, improve reliability, and reduce the burden on firefighters.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This embodiment provides a backpack shock-absorbing mobile fire extinguishing device equipped with a shock absorber, which can reduce the force transmitted to firefighters when they carry the fire extinguishing device for mobile operations.

[0030] like Figures 1-3 As shown, the fire extinguishing device includes: a fixed plate 1, a pressure plate 4, a shock absorber 6, and a water tank 7; wherein the water tank 7 is slidably engaged with the fixed plate 1, and the water tank 7 can slide up and down relative to the fixed plate 1.

[0031] As an example, the fixing plate 1 is made of carbon fiber, which can reduce weight by more than 30% compared to a traditional metal frame while maintaining impact resistance. The fixing plate 1 can be connected to shoulder straps of different materials and shapes through reserved interfaces.

[0032] As an example, a guide rail 2 is provided on the fixed plate 1, and a guide rail 3 is fixed to the fixed plate 1 by bolts; a slider 3 is provided on the water tank 7, which slides with the guide rail 2, and the slider 3 is fixedly connected to the back of the water tank 7 by bolts; the slider 3 can slide up and down on the guide rail 2; thus, the sliding engagement between the water tank 7 and the fixed plate 1 is achieved. In this example, two guide rails 2 are arranged side by side on the fixed plate 1, and correspondingly, two sliders 3 are arranged side by side on the back of the water tank 7. As an example, baffles are provided at both ends of the slider 3 to restrict it from sliding out of the guide rail 2.

[0033] The shock absorber mounting base 5 is fixed to the mounting plate 1, and the shock absorber 6 is vertically mounted on the shock absorber mounting base 5. As an example, the shock absorber mounting base 5 has a right-angle structure, with its vertical part fixed to the mounting plate 1 by bolts, and its horizontal part used to mount the shock absorber 6. The shock absorber 6 is preferably a hydraulic shock absorber.

[0034] The pressure plate 4 is fixed to the back of the water tank 7 by bolts and is located above the shock absorber 6. When the pressure plate 4 moves down with the water tank 1, it can contact the shock absorber 6, thereby enabling the shock absorber 6 to buffer and dampen the water tank 7.

[0035] As an example, the shock absorber 6 is located in the middle of the width direction of the back of the water tank 7. Two sliders 3 are symmetrically arranged on the left and right sides of the shock absorber 6. The pressure plate 4 is a horizontally arranged strip plate. The bolts used to fix the two sliders 3 pass through the two ends of the pressure plate 4 and are fixed to the back of the water tank 7, thereby realizing the installation of sliders 3 and pressure plate 4 on the water tank 7.

[0036] like Figure 4 As shown, in addition, several partitions 8 are spaced along the height of the water tank 7. The partitions 8 are plate structures with a number of permeable holes, which divide the internal space of the water tank 7 into several small spaces from top to bottom, while the small spaces are interconnected. Thus, when the water tank 7 is not full of water, the partitions 8 can passively reduce the liquid fluctuations in the water tank 7 caused by firefighters moving, thereby reducing the shear force and inertial force of the liquid on the water tank 7.

[0037] When firefighters are carrying the aforementioned shockproof mobile fire extinguishing device, initially, the pressure plate 4 is in contact with the top of the shock absorber 6. During the running process, due to the inertial force, the water tank 7 will move up and down relative to the fixed plate 1. Due to the setting of the guide rail 2 and the slider 3, the water tank 7 will passively slide along the guide rail 2. When the water tank 7 rises, the pressure plate 4 loses contact with the shock absorber 6. When the water tank 7 moves from top to bottom, it slides along the guide rail 2, causing the pressure plate 4 to contact the top of the shock absorber 6. Under the action of the shock absorber 6, the effect of inertial force is significantly reduced.

[0038] This shockproof mobile fire extinguishing device reduces the force transmitted to firefighters when they carry it during operations by using shock absorbers and partitions 8. In addition, by using carbon fiber composite materials, it is more than 30% lighter than traditional metal frames while maintaining impact resistance, significantly reducing the stress on firefighters.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
