Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.

As shown in Fig. 1 ~ 3, the back-pack electric high-pressure fire extinguishing apparatus, including including water tank 1, brace 2, battery 3, every Membrane pump 4, flexible pipe 5, hold a writing brush or pen-write 6, shower nozzle 7, and described hold a writing brush or pen-write is provided with tapping valve 61 on 6, and 6 afterbody of holding a writing brush or pen-write is installed with and holds set 62, the shower nozzle 7 includes outer tube 71, inner tube 72, and the length of said inner tube 72 is less than the length of outer tube 71, said inner tube 72 and outer Clutch shaft bearing 73 and second bearing 74 are provided between pipe 71, clutch shaft bearing 73 is located at the stem of inner tube 72, the clutch shaft bearing 73 outer ring is fixedly connected with the inwall of outer tube 71, and the inner ring of the clutch shaft bearing 73 is fixedly connected with the outer wall of inner tube 72, institute The afterbody that second bearing 74 is located at inner tube 72 is stated, the outer ring of the second bearing 74 is fixedly connected with the inwall of outer tube 71, described The inner ring of second bearing 74 is fixedly connected with the outer wall of inner tube 72；Set between the afterbody of said inner tube 72 and the afterbody of outer tube 71 There is an interval, said inner tube 72 is internally provided with helical blade 721, and helical blade 721 is fixedly connected with the inwall of inner tube 72；Institute 6 stem of holding a writing brush or pen-write is stated to connect with the afterbody of outer tube 71.Further, 6 lower section of holding a writing brush or pen-write is provided with stock 8, the tail of stock 8 Portion, which is installed with C-shaped clamping part 81, the opening of clamping part 81, is provided with projection 811；The afterbody for holding set 62 is installed with nut 621, it is threadedly coupled between the stem and nut 621 of the stock 8.Further, the top of the water tank 1 is installed with VELCRO 9。

Fire-fighting foams liquid or fire water are stored in water tank 1, by taking fire-fighting foams liquid as an example, membrane pump 4 is by disappearing in water tank 1 The pressurization of foam-resistant liquid exports into high-pressure fluid, and high-pressure fluid passes sequentially through flexible pipe 5, hold a writing brush or pen-write 6, the finally ejection at shower nozzle 7；Its In, brace 2 is easy to bear the back-pack electric high-pressure fire extinguishing apparatus on the body of fire fighter, and battery 3 is membrane pump 4 There is provided electric power makes its work.When fireman holds with a firm grip set 62, opens tapping valve 61,6 high-pressure fluid of holding a writing brush or pen-write is quickly entered In outer tube 71, inner tube 72, due to the presence of clutch shaft bearing 73 and second bearing 74, inner tube 72 can be rotated in outer tube 71, work as height When pressing fluid by inner tube 72, when high-pressure fluid passes through helical blade 721, thrust, the thrust meeting can be produced to helical blade 721 Inner tube 72 is driven to rotate, and during this, helical blade 721 can destroy the outermost flow regime of high-pressure fluid, helical-blade The rotation of piece 721 can produce centrifugal force so that the moment that high-pressure fluid just sprays from inner tube 72 forms the jet of large area, jet Drop in small, broken bits is in edge and remains in that enough firing rates, for typical circular jet pipe, in Fluid pressure identical In the case of, although the range of shower nozzle 7 is the 90% ~ 95% of typical circular jet pipe range, but the projected area of shower nozzle 7 is common circle 2.3 ~ 2.8 times of shape jet pipe projected area, what the fluid that the projected area of the shower nozzle 7 is sprayed with shower nozzle 7 was projected in horizontal plane Area represents that the range of the shower nozzle 7 refers to the maximum horizontal range that the jet sprayed from shower nozzle 7 is projected.Wherein, first The totally enclosed type bearing of good airproof performance may be selected in bearing 73 and second bearing 74.

6 are held a writing brush or pen-write so that the limited height that the fluid that shower nozzle 7 sprays reaches, can now pacify the stem of stock 8 due to hand-held On nut 621, as shown in figure 4, by the afterbody of hand-held stock 8 extinguishing operation can be carried out to the ignition point of higher height； During being somebody's turn to do, the flexible pipe 5 for 6 annexes that hold a writing brush or pen-write can be caught in clamping part 81, the resistance that the flexible pipe 5 of 6 annexes that holds a writing brush or pen-write is brought is reduced；Clamping Portion 81 is that C-shaped conveniently blocks flexible pipe 5 and takes out flexible pipe 5, and projection 811 can be prevented effectively from flexible pipe 5 and be come off from clamping part 81.When not During using stock 8, stock 8 is pulled down from nut 621, then stock 8 put upside down, then stock 8 is tied up using VELCRO 9 On water tank 1, now clamping part 81 can also prevent stock 8 from dropping.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
