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
The present invention relates to a kind of extinguishing device, be specifically related to a kind of extinguishing water cannon.
Background technology
Existing fire-fighting fire extinguishing gun is because structural design restriction can only produce single parabola shape point and spray during jetting, and efficient was not high when large tracts of land was put out a fire, even the situation of the condition of a fire occurred incuring loss through delay, can not adapt to the needs of modern fire-fighting fully.How under identical flow condition, to realize the comprehensive injection that rotation (ellipse) sphere-like distributes, thereby reach the rapid large-area ejecting extinguishing, have very realistic meanings.
Summary of the invention
The object of the present invention is to provide that a kind of spray regime is big, fire-fighting efficiency is high, the rotation type ejecting extinguishing water cannon flexibly of working.
For reaching above-mentioned purpose, a kind of rotation type ejecting extinguishing water cannon provided by the invention comprises water inlet pipe and faucet body, and described faucet body is bearing in an end of water inlet pipe by rotating member, and the inside of faucet body has water cavity, and water cavity is communicated with water inlet pipe; Described faucet body is made up of protecgulum and bonnet, and the junction of protecgulum and bonnet is provided with the rotating mechanism water shutoff exhaust outlet of slit-shaped; It is planar that described protecgulum is hemisphere, is distributed with a plurality of delivery ports on it, and the cross section of delivery port is trapezoidal shape, and the bore of delivery port the inside is greater than the bore of outside.
Rotating member of the present invention can adopt rotating members commonly used such as bearing or ball.
Water inlet pipe of the present invention and faucet body are positioned at outside junction and are provided with a jump ring, and jump ring is stuck on the water inlet pipe, is provided with metallic gasket between jump ring and the faucet body.The effect of jump ring is to prevent to separate between extinguishing water cannon when work water inlet pipe and the faucet body, and metallic gasket then has and prevents the faucet body effect that directly rubs with faucet body of jump ring when rotated, thus the service life of prolongation extinguishing water cannon.
Can be connected and fixed by screw between the protecgulum of faucet body of the present invention and the bonnet.
When the present invention works, water enters the water cavity of faucet body through water inlet pipe, because the planar protecgulum of hemisphere that is of faucet body is provided with the delivery port that a plurality of cross sections are trapezoidal shape, this moment, water inlet was quickened ejection by delivery port, faucet body is subjected to a reverse stamping press of water outlet simultaneously, faucet body rotatablely moves automatically by rotating member, the centrifugal force that faucet body rotation produces forms the water of delivery port ejection that continuous screw is planar to eject by the difference of its angle of water, thereby form the space water shape of (ellipse) sphere-like, reach the effect of rapid large-area ejecting extinguishing.
Compare with traditional extinguishing water cannon, the present invention has following characteristics:
1. protecgulum is designed to the planar and a plurality of delivery ports that distribute of hemisphere on the protecgulum of this dome shape, and it is even from all directions ejaculation and water outlet to help water outlet.
2. the Cross section Design of delivery port shape in echelon, the bore of delivery port the inside can strengthen the jetting flow velocity of delivery port greater than the bore of outside, when satisfying certain flow, can reduce feed pressure.
3. the junction of protecgulum and bonnet is provided with the rotating mechanism water shutoff exhaust outlet of slit-shaped, water cavity is full of water during because of the faucet body rotary-jet, equal discharge pressure all will be born in any position in the water cavity, as not leaving suitable water shutoff exhaust outlet, the flow of water in the water cavity must be under pressure and enter rotating member from the rotating member slit and come out from the slit high velocity jet of the rotating member other end, can cause the rotating member cisco unity malfunction, and the effect of water shutoff exhaust outlet is when water cavity is full of water and before water arrives the rotating member slit current are therefrom shunted away, the rotating member slit forms negative-pressure air-flow from the back forward direction, stop current to enter in the rotating member, guarantee the operate as normal of rotating member, thereby prolong the service life of product.
In sum, the present invention has characteristics such as the jet space scope is big, fire-fighting efficiency is high, work is flexible, long product lifecycle.
The invention will be further described below in conjunction with the drawings and the specific embodiments.
