Description
Technical field:
The utility model relates to a kind of fire-fighting fire extinguishing water cannon, is particularly useful for the fire-fighting of boats and ships aspect.
Background technology:
Original S type fire monitor, its structure comprises cover 2, overcoat 3, outer bell and spigot joint 4, bend pipe 5, bend pipe 6, lubricating cup 7, handle 8, taper knob 9, plug 10, keyway 11, lock sleeve 12, screw rod 13, lock sleeve 14, plug 15, trim ring 16, the tightening handle 17 of can transposing in inlet flange 1, the level as shown in Figure 1 and Figure 2.This kind S type fire monitor profile is more stiff, and center of gravity is than higher, and it is bigger to make force rate after the center of gravity height has caused, and it is serious to cause energy to run off.This kind fire monitor utilizes lock sleeve to carry out locking positioning, but waits similar place of rocking to use aboard ship, and the center of gravity height also can aggravate the wearing and tearing of lock sleeve, and this kind feel fire monitor complex structure keeps in repair very inconvenient simultaneously.
Summary of the invention:
The utility model has improved the fire monitor of said structure, and is not only handsome in appearance, reasonable in design, and the horizontal rotation of big gun body and facing upward bow regulate all very convenient.
The purpose of this utility model realizes by following measure:
A kind of fire monitor, it comprises nozzle, gun tube, faces upward the mechanism of bowing, horizontal rotation mechanism and barrel, it is characterized in that described gun tube rear portion employing swinging counter weight construction.
The design of centre of gravity of gun tube is on the central axis of barrel.
The shaft type counter weight construction that returns of gun tube is formed by connecting by three parts, comprises L type bend pipe, 90 ° of bend pipes and 180 ° of bend pipes, and three groups of bend pipes link to each other by joint.
The barrel middle part is provided with horizontal rotation mechanism, slew gear is provided with inside and outside cover, interior cover is connected with the barrel bottom, overcoat and barrel top are connected, lining the outer surface of is provided with one section worm gear, overcoat disposes a cavity, is provided with worm screw in the chamber and cooperates with described worm gear, and the link at worm screw rear portion links to each other with driving motor.
Interior cover is connected with the barrel bottom; Overcoat and barrel top are connected.
The junction of gun tube and barrel is provided with faces upward the mechanism of bowing, face upward the mechanism of bowing and be provided with inside and outside cover, interior cover is connected with the barrel top, overcoat and barrel rear portion are connected, interior cover outside table is provided with one section worm gear, overcoat disposes a cavity, is provided with worm screw in the chamber and cooperates with described worm gear, and the link at worm screw rear portion links to each other with driving motor.
Worm screw radially is arranged in the cavity of overcoat.
In be placed in to be provided with between the upper and lower position of worm gear position and the overcoat and support steel ball and sealing ring.
The cavity that puts outward only is being provided with opening with interior cover sides adjacent, and worm gear cooperates with this aperture position with worm screw.
The utility model has following advantage compared to existing technology:
1) former S type fire monitor is at the left rotation and right rotation locking device not under the lock state, and big gun water spray, big gun are known from experience and influenced to a direction by recoil to rotate, and aggravated serious to the wearing and tearing of the locking device of big gun and the pressure loss simultaneously.
Back geometric pattern fire monitor is at the left rotation and right rotation locking device not under the lock state, big gun water spray, the big gun body can not be subjected to the influence of recoil and occurrence positions changes, and can the locking device of big gun not exerted an influence simultaneously, the pressure loss is smaller, can obtain the range of current and Geng Gao more stably and penetrate height.
2) former S type fire monitor position of centre of gravity height is having the place of rocking, and for example on the ship, is easy to generate and rocks, and transmission device is easy to wear; State downforce loss in work is also bigger than the big gun of back geometric pattern in addition.
The utility model adopts back geometric pattern big gun lighter than original S type fire monitor operation, and the kick of fire monitor water spray decomposes more stable, and is better to the transmission device protection of big gun; more reasonable; also than more steady originally, the pressure loss is less for current, can obtain better range and penetrate height.
The center of gravity of back geometric pattern big gun is lower, even in the place of rocking easily, stability is also relatively good; And duty downforce loss reduce and reached obtain better range and penetrate high purpose.
This fire monitor is had a graceful figure; Reduced the height of center of gravity, after to make force rate less, Energy Efficient rate height, flow rate of water flow is fast, outlet pressure is relatively big; Utilize stainless steel tie down screw locking positioning, be not easy wearing and tearing, even be in the rocking in the environment of similar ship, because center of gravity is lower, tie down screw is not easy to wear, can realize reliable positioning and locking, and is not fragile; Locking mechanism is fairly simple, keeps in repair more convenient.
