Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

As shown in Figure 1, a kind of fire-fighting lance, comprise a sparge pipe 1, this fire-fighting lance also comprises an injector aid 2, the center of this injector aid 2 is disposed with the pressure inlet 21, be communicated with in turn and helps and penetrate chamber 22 and and help and penetrate pipe 23, this pressure inlet 21 is connected with the end of this sparge pipe 1, and the diameter of this pressure inlet 21 is less than the diameter of this sparge pipe 1 and this helps the diameter penetrating pipe 23, and this helps to penetrate on chamber 22 and is provided with more than one injecting hole 24.Current in this sparge pipe 1 are when this pressure inlet 21, and circulation area is less, thus pressure and flow velocity are improved, and the diameter of water column is also less; This water column through this help penetrate chamber 22 inject this help penetrate pipe 23 time, can drive ambient air together directive this help and penetrate pipe 23, make water column and help to penetrate between pipe 23 to form air cushion, effectively reduce water column and help the frictional force of penetrating between pipe 23 inwall, thus the friction loss of water column can be reduced, improve the range of water column.This structure is comparatively simple, and production cost is higher, under same hydraulic pressure, effectively can improve the range of water column.

This pressure inlet 21 is connected by pyramidal structure transition with this sparge pipe 1, and this helps is penetrated chamber 22 and help with this and penetrate pipe 23 and to be filtered by pyramidal structure and be connected.Pyramidal structure further can reduce the resistance of water column or air, reduces energy loss.

This injector aid 2 is provided with a connection chamber 25, this connection chamber 25 is provided with more than one air admission hole 26, this injecting hole 24 is communicated with this to be helped and penetrates chamber 22 and this connection chamber 25.This connection chamber 25 is set and can protects this injecting hole 24, can also make user that the position of air admission hole 26 is conveniently set, make this injector aid 2 more attractive in appearance.

This air admission hole 26 is arranged on the rear end of this connection chamber 25, and the axis of its axis and this sparge pipe 1 is parallel to each other.If the radial direction along this connection chamber 25 arranges this air admission hole 26, then in use, air admission hole 26 is easily blocked by staff, affects the range of this fire-fighting lance, makes this injector aid 2 attractive in appearance not simultaneously.

This fire-fighting lance also comprises an injection spray pipe 3, this injector aid 2 is provided with a bridge joint chamber 27, and this bridge joint chamber 27 is provided with multiple atomizer 28, and this injection spray pipe 3 is connected with this bridge joint chamber 27.Arranging sprayer 28 can make fire-fighting lance spray water smoke, and these water smokes, can improve the extinguishing effect of fire-fighting lance at a distance helping directive under the drive of penetrating the water smoke that pipe 23 sprays.

The plurality of atomizer 28 is arranged in this uniformly and helps the surrounding of penetrating pipe 23.The water column that this structure can utilize this playpipe 23 to eject to greatest extent.

This injection spray pipe 3 is arranged in parallel with this sparge pipe 1 and is connected with this bridge joint chamber 27 through this connection chamber 25.Be conducive to the overall dimensions reducing this fire-fighting lance.

Below only in one embodiment mentality of designing of the present utility model is described, when system allows, the utility model can expand to external more functional module simultaneously, thus expands its function to greatest extent.

The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
