Problems solved by technology

[0002] Due to structural design limitations, the existing fire extinguishing guns can only produce a single parabolic point spray when spraying water, which is not efficient for large-scale fire extinguishing, and even delays the fire situation. It can no longer fully meet the needs of modern fire fighting. up

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 ...

Abstract

Disclosed is a rotation type ejecting extinguishing water cannon, which comprises a water inlet pipe and a water nozzle body, wherein the water nozzle body is supported onto one end of the water inlet pipe through rotary members, the water nozzle body is provided with water chambers inside, the water chambers are in communication with the water inlet pipe, the water nozzle body comprises a front cover and a rear cover, a slot shape water shutting of air exhaust opening is arranged at the junction portion of the front cover and the rear cover. The front cover is in semi-spherical shape with a plurality of water outlets having ladder type cross sections, the inner caliber of the water outlet is larger than the outer caliber. The device can realize quick-speed large area sprinkling fire extinction.

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 ...
