Description

technical field

[0001] The invention relates to a fire extinguishing device, in particular to a fire extinguishing water monitor. Background technique

[0002] Due to structural design limitations, the existing fire extinguishing monitor can only produce a single parabolic point jet when shooting water, which is not efficient for large-scale fire extinguishing, and even delays the fire situation, which can no longer fully meet the needs of modern fire fighting. . How to realize the omnidirectional spray of rotating (ellipsoidal) spherical distribution under the same water flow conditions, so as to achieve rapid and large-area spray fire extinguishing, has very practical significance. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide a rotary jet fire extinguishing water cannon with large spray range, high fire extinguishing efficiency and flexible operation.

[0004] In order to achieve the above purpose, the present invention provides ...

Examples

Embodiment Construction

[0019] like figure 1 ~4, the rotary jet fire extinguishing water monitor of the present invention includes a water inlet pipe 1 and a water nozzle body 2 . The faucet body 2 is supported on one end of the water inlet pipe 1 by the rotating member 3 , and the water nozzle body 2 has a water cavity 4 inside, and the water cavity 4 communicates with the water inlet pipe 1 . The faucet body 2 is composed of a front cover 5 and a rear cover 6. The connection between the front cover 5 and the rear cover 6 is provided with a slit-shaped rotating mechanism to seal the water exhaust port 7; There are a plurality of water outlets 8, the section of the water outlet 8 is trapezoidal, and the inner diameter of the water outlet 8 is larger than the outer diameter.

[0020] The rotating member 3 of the present invention can be a common rotating member such as a bearing or a ball, figure 2 Bearings shown.

[0021] The connection between the water inlet pipe 1 and the faucet body 2 of the ...
