Abstract

The utility model provides a hydraulic-driven wide area firing gun, which comprises a lifting frame, a chassis, a rotary disk, a support frame, a center shaft, a fixed pin, three extending cylinders, a firing gun and a water supply pipe. The hydraulic-driven wide range firing gun has the advantages of novel structure, long distance of water jetting, and large discharging amount, can realize wide area firing, has particularly a better effect of wide area firing for oilfields and oil wells, and can be widely used for wide area firing for oilfields and oil wells.

Description

Hydraulic-driven wide range firing gun

The utility model relates to a kind of fire-fighting equipment device, particularly a kind of hydraulic-driven area fire gun.

What China used in fire-fighting fire extinguishing at present all is giant, and beam is a line, and not only Mie Huo area is little, and the effect of fire extinguishing is also bad.

The purpose of this utility model provides a kind of hydraulic-driven area fire gun.It not only can be realized large-area fire extinguishing, but also can realize the large-area cooling of object.

The purpose of this utility model is achieved in that it includes crane, the chassis, rotating disc, support, central shaft, the rotating disk steady pin, three telescoping cylinders, fire gun, feed pipe constitutes, it is characterized in that on the chassis, being equipped with rotating disc, support and central shaft are equipped with in the rotating disc top, central shaft is fixed on the crane by the chassis, on support and steady pin, be connected a telescoping cylinder, one steering link is installed on central shaft, another telescoping cylinder is installed between the small end of central shaft and steady pin, an end is equipped with small rack on support, small rack links to each other with fire gun (gun barrel), fix its another telescoping cylinder on the other end on the support and the small rack, feed pipe directly inserts the fire gun gun barrel, crane is installed under the chassis, and water injection nozzle is welded on the top of fire gun.

The utility model has the advantages that novel structure, jetting is far away, and discharge capacity is big, can realize the large tracts of land fire extinguishing, particularly to oil field, the fire extinguishing of oil well large tracts of land, effect is better, also can realize the object large tracts of land is lowered the temperature, and can be injected into movable transparent cascade and carry out heat insulation, the shielding fire fighter can also make large tracts of land fire-fighting rainfall near the scene of a fire, reduces the intensity of a fire, foam fire-fighting can also be discharged, the fire extinguishing of suction air method can be adopted catching fire of oil storage tank.

Do the embodiment explanation below in conjunction with accompanying drawing.

Accompanying drawing is a structure chart of the present utility model.

By accompanying drawing as can be known, hydraulic pressure fire gun 2 is installed on the crane 8, fixed underpan 6 is installed on crane 8, fixed axis is equipped with at 6 centers, chassis, bearing is installed on the axle, revolve a chassis 12 and be inlaid on the bearing, a stationary links 7 is installed on fixed axis, an end of telescoping cylinder 11 links to each other with stationary links 7, the other end links to each other with steady pin, can make the fire gun horizontal hunting, axle sleeve 14 is installed on the steady pin, and support 5 is installed on rotating disc, telescoping cylinder 10 links to each other with support 5, can make fire gun do horizontal vertical swing, be equipped with small rack 17 at the other end of support 5, small rack 17 links to each other with fire gun gun barrel 2, the other end at small rack 17 and support 5 is connected with telescoping cylinder 4, can make fire gun do the swing at the elevation angle, connect feed pipe 3 at the middle part of fire gun gun barrel 2, feed pipe 3 adopts high-pressure hose to be convenient to movable rotation, be fixed on the crane 8 by pipe clamp 16, the welding of crane 8 usefulness angle steel, telescoping cylinder all adopts standard hydraulic cylinder, and each telescoping cylinder all has two catheters.For the ease of the rotating disc rotation, catheter all is fixed on the crane 8, adorns a water injection nozzle 1 on the top of fire gun 2, and water injection nozzle will have certain-length to be the flat aquaporin of crossing, and is used for controlling the beam of water.

Operation principle: when high-pressure gas well catches fire, can adopt two fire guns to use simultaneously, direction from two symmetries, be same angle correlation, gradually to aerial correlation, its high pressure water surface is used to isolate kindling material by lower, reduce temperature, prevent that kindling material from rolling to the well head direction, because natural gas sprays former non-flammable compressive gas ingress of air at a high speed in well, run into by on scurry the kindling material that gets off, just burning immediately, the current that fire gun is launched are although can not penetrate High pressure air pole, but can change its direction, can isolate kindling material fully, two-way beam is looked like same barrier, can prevent that not only kindling material from rolling to the source of the gas direction, but also can take the cooling cooling to well head, the high temperature of former burning-point is constantly lowered the temperature, dwindle combustion range, reach the purpose of fire extinguishing.When oil tank catches fire, available fire gun adopts the method for suction air, allows the high pressure water surface of fire gun be parallel to jar mouthful, the high pressure water surface is skimmed over from the jar mouth, form low-pressure area, the suction power of utilizing fire gun to produce is come air and the flame in the Suction cop, reaches the purpose of fire extinguishing.

Claims
