The technical solution of the utility model is such: fire monitor big gun head, comprise big gun head body, the tube of blooming, gun barrel, water outlet block and driving mechanism, outside with the direction of current being, above-mentioned outer end of blooming tube is provided with horn-like delivery port, above-mentioned water outlet block is arranged in this horn-like delivery port, and above-mentioned water outlet block and above-mentioned big gun head body are fixed as one, it is external that an above-mentioned mode by screw thread of blooming is socketed on above-mentioned big gun head, above-mentioned gun barrel is socketed in outside the above-mentioned tube of blooming, above-mentioned gun barrel can move around along above-mentioned axial direction of blooming tube under the driving of above-mentioned driving mechanism, stretch out outside the above-mentioned tube of blooming the inner of above-mentioned big gun head body, the above-mentioned tube of blooming is provided with traffic conditioner block, the inner of above-mentioned big gun head body is stretched out above-mentioned a section of blooming tube and is provided with the corresponding a plurality of locating slots of traffic conditioner block difference therewith, and these a plurality of locating slots are provided with at interval along the circumferencial direction of above-mentioned big gun head body.
Above-mentioned gun barrel and above-mentionedly bloom that the mode by screw thread connects together between the tube, above-mentioned driving mechanism comprises motor, first gear and second gear, the above-mentioned motor and first gear are fixed on outside the above-mentioned gun barrel by a bearing, the above-mentioned second gear fixed cover is located on the outer wall of above-mentioned gun barrel, and above-mentioned first gear and above-mentioned second gear are meshing with each other.
The outer wall of above-mentioned gun barrel is provided with handwheel.
After adopting such scheme, fire monitor big gun head of the present utility model is provided with traffic conditioner block on the tube of blooming, and big gun head body is provided with the corresponding respectively a plurality of locating slots that are provided with at interval along the circumferencial direction of big gun head body of traffic conditioner block therewith.The beneficial effects of the utility model are: when needs are regulated flow, the tube that only needs to bloom rotates relative to big gun head body, traffic conditioner block is forwarded in the locating slot of required flow correspondence, bloom and carry out the axial relative motion of corresponding stroke by screw thread between tube and the big gun head body, changed the water outlet block and the horn-like delivery port of the tube of blooming between the discharge area, thereby changed the flow of big gun head.And in the utility model, blooming also socket-connects by screw thread between tube and the gun barrel, and the driving mechanism of gun barrel is a gear drive, when electricity is arranged, can drive the relative axially-movable of blooming of gun barrel with gear drive by motor, thereby realize the conversion of spraying and direct current; When not having electricity, also can pass through the hand rotation gun barrel, make a gun barrel axially-movable of blooming relatively, conversion with direct current also can realize spraying; The utility model also is provided with handwheel at the gun barrel outer wall, helps the hand rotation gun barrel.

The specific embodiment
Fire monitor big gun head of the present utility model, as shown in Figure 1, 2, 3, comprise big gun head body 1, bloom tube 2, gun barrel 3 and water outlet block 4, big gun head body 1, bloom tube 2 and gun barrel 3 all are cylinder-like structure, and big gun head body 1 with bloom between the tube 2 and bloom tube 2 and gun barrel 3 seal by sealing ring respectively.
Outside with the direction of current being, tube 2 the outer end of blooming is provided with horn-like delivery port 21, water outlet block 4 is arranged in this horn-like delivery port 21, the inner chamber of big gun head body 1 is provided with the rectifier 11 of blade construction, the middle part of rectifier 11 is provided with screwed hole, water outlet block 4 is fixed in this screwed hole by bolt 41, thereby water outlet block 4 and big gun head body 1 are fixed as one.
Tube 2 modes by screw thread of blooming are socketed on outside the big gun head body 1, gun barrel 3 is socketed in outside the tube 2 of blooming by the mode of screw thread, stretch out outside the tube 2 of blooming the inner of big gun head body 1, bloom the tube 2 on fixed cover be provided with gear frame 5, be placed on the gear frame 5 on the ring-type position outside the tube 2 of blooming and be provided with traffic conditioner block 6 by bearing pin, support between the outer end of traffic conditioner block 6 and the gear frame 5 and be provided with spring 61, the inner of traffic conditioner block 6 is provided with locating piece 62, and one section corresponding three locating slot 12 of locating piece 62 difference that along the circumferential direction are arranged at intervals with traffic conditioner block 6 of the tube 2 of blooming are stretched out in the inner of big gun head body 1,13,14.
Gear frame 5 is provided with motor 51, decelerator 52 and gear 53, and the outer wall fixed cover of gun barrel 3 is provided with gear 31, and gear 53 is meshed with gear 31, is set with handwheel 7 on the outer wall of gun barrel 3.
When needs are regulated flow, the locating piece 62 of traffic conditioner block 6 is pulled out from locating slot, the tube 2 of will blooming rotates relative to big gun head body 1, locating piece 62 is gone in the locating slot that snaps in required flow correspondence, bloom and carry out the axial relative motion of corresponding stroke by screw thread between tube 2 and the big gun head body 1, change water outlet block 4 and the discharge area between tube 2 the horn-like delivery port 21 of blooming, thereby changed the flow of big gun head.
When electricity was arranged, the output shaft of motor 51 connected gears 53 through decelerator 52 back, by gear 53 driven gears 31, rotated relative to the tube 2 of blooming thereby drive gun barrel 3, finally drove gun barrel 3 tube 2 axially-movables of blooming relatively, realized spraying and the conversion of direct current.When not having electricity,, make gun barrel 3 tube 2 axially-movables of blooming relatively, also can realize spraying and the conversion of direct current by handwheel 7 hand rotation gun barrels 3.
