Technical Field
The utility model belongs to the technical field of fire fighting equipment, and particularly relates to a wearable spray head for fire fighting.
Background
In the research and development process of fire scene open-circuit equipment, a large number of different spray heads are used, and the technical requirements cannot be met no matter the spray heads are post night machine spray heads or atomizing spray heads, so that on the first hand, the existing spray heads have unsatisfactory range; in a second aspect, the existing spray head has a plurality of components, cannot be directly connected with a high-pressure pipe, and has a multi-point leakage risk; in a third aspect, quick change of the spray head is not possible.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is realized by adopting the following technical scheme:
a wearable spray head for fire fighting comprises a spray pipe and a connecting pipe, wherein the connecting pipe is connected to one end of the spray pipe and used for connecting a pipeline, a water spraying hole is formed in the spray pipe, a water inlet hole is formed in the connecting pipe, the water inlet hole extends into the spray pipe and is connected with the water spraying hole, and the ratio of the diameter d to the length l of the water spraying hole is 1.5: 16.
The diameter D of the water spray hole is one fourth of the diameter D of the water inlet hole.
And the connecting pipe is provided with a mounting thread for connecting a pipeline joint.
Rifling is processed on the inner wall of the water spraying hole.
One end of the spray pipe, which is far away from the connecting pipe, is in a round table shape.
The wearable fire-fighting sprinkler further comprises a fixing part for fixing the sprinkler on an external object.
The fixed part comprises a fixed base and a clamping bolt, the fixed base is connected to the bottom of the spray pipe, fixed holes are formed in two sides of the fixed base respectively, and the clamping bolt is installed in the fixed holes.
The fixing part also comprises a gasket, mounting holes corresponding to the fixing holes are formed in the gasket, and the clamping bolts penetrate through the corresponding mounting holes.
The utility model has the advantages and positive effects that: under equal liquid pressure, the range of this shower nozzle can increase more than 20%, and, this shower nozzle can form through integration processing, only the tail end has the interface of connecting the high-pressure pipe, reduce one to two interfaces than traditional shower nozzle, leakage hidden danger has been reduced, and simultaneously, the butterfly design of fixed part, use the tight screw of clamp to closely fix upper and lower two parts, the lifting surface area of fixed point has been increased, can not drop easily after receiving strong impact, after the shower nozzle breaks down, also only need unscrew the screw just can quick replacement.
