Description
Technical field
The utility model relates to fire-fighting equipment field, is specifically related to a kind of fire-fighting lance.
Background technology
Fire-fighting lance is the most frequently used inside fire-fighting equipment, also modal, very common, the frequency height very of use, it is existing that commercially modal hydraulic giant water outlet is columned often, the efficiency of fire extinguishing can be improved at the initial stage columned water-out manners of fire extinguishing, concentrated water source extinguishes the blaze, but along with the propelling of fire extinguishing process, the inefficiency that columned water-out manners is just aobvious, and waste water resource, increase the time of fire extinguishing.
Utility model content
For overcoming deficiency of the prior art, the utility model provides a kind of fire-fighting lance that effectively can increase fire-fighting fire extinguishing efficiency, expand fire extinguishing scope.
7, for achieving the above object, the technical solution adopted in the utility model is as follows: a kind of fire-fighting lance, comprise hydraulic giant gun barrel, shower nozzle, water side, hydraulic giant gun barrel front end is hollow cylinder structure, shower nozzle is hollow cylinder structure, it is characterized in that: described water side, hydraulic giant gun barrel front end is provided with three projections on its edge, shower nozzle water intake end inwall is provided with three grooves, is provided with annular groove below groove.
8, further, described three convex wherein two become 180 °, another one projection and other two pieces of projections in 90 °.
9, further, three described grooves wherein two become 180 °, another one groove and other two grooves in 90 °
10, further, described shower nozzle water side is uniformly distributed with water outlet through hole, and water outlet through hole edge is dentation.
Further, described shower nozzle inwall is provided with water outlet through hole.
11, further, the water outlet through hole on described shower nozzle inwall becomes 5-60 ° with showerhead central axis line.
12, seen from the above description, a kind of fire-fighting lance that the utility model provides can change output patterns by increasing shower nozzle, from cylinder water column to umbrella, different water-out manners can be used in the different phase of fire extinguishing, improve the efficiency of fire extinguishing, current can spread out and increase the area of current covering by the water outlet through hole of dentation, and it is simple, efficient, convenient to install, and greatly improves the efficiency of fire extinguishing and the time reducing fire extinguishing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fire-fighting lance of the utility model.
Fig. 2 is the front view of a kind of fire-fighting lance of the utility model.
Fig. 3 is the structural representation of a kind of fire-fighting lance of the utility model.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model relates to a kind of fire-fighting lance, comprise hydraulic giant gun barrel 1, shower nozzle 2, water side, hydraulic giant gun barrel 1 front end is hollow cylinder structure, shower nozzle 2 is hollow cylinder structure, it is characterized in that: described water side, hydraulic giant gun barrel 1 front end is provided with three projections 11 on its edge, shower nozzle 2 water intake end inwall is provided with three grooves 21, annular groove 22 is provided with below groove 21, three projections 11 wherein two become 180 °, another one projection 11 is in 90 ° with other two pieces of projections 11, three grooves 21 wherein two become 180 °, another one groove 21 is in 90 ° with other two grooves 21, shower nozzle 2 water side is uniformly distributed with water outlet through hole 23, water outlet through hole edge is dentation, logical 23 holes of water outlet on shower nozzle 2 inwall become 5-60 ° with shower nozzle 2 central axis.
As shown in the figure, a kind of fire-fighting lance of the utility model, in use, three projections 11 aim at three grooves 21, and pressing is entered, rotation meets and discusses 2, make the projection 11 on hydraulic giant gun barrel 1 be stuck on annular groove 21, after water flowing, the pressure of current is by shower nozzle 2 pushing down with hydraulic giant gun barrel 1 tightly, and current form umbrella by being broken up by current post after the water outlet through hole 23 of dentation with the water outlet of the through hole on shower nozzle 2 inwall, the current area coverage increased, improves the efficiency of fire extinguishing in the later stage of fire extinguishing.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
