Abstract
The utility model discloses an automatic-rotation spray nozzle which comprises a rotary spray module, a centrifugal wheel and an axle bracket assembly, wherein the rotary spray module is fixedly arranged on the axle side of the centrifugal wheel, a blind hole is formed in the axial direction of the centrifugal wheel, the axle bracket assembly is fixedly arranged inside the blind hole, a front tapered positioning device is arranged at the bottom end of the centrifugal wheel, a through hole is formed in the radial direction of the centrifugal wheel, and one end of the through hole is communicated with the axial blind hole and the other end of the through hole faces to the inclined surface of the rotary spray module. The automatic-rotation spray nozzle works without needing power, and has a high rotational speed and a wide spraying range.
Description
Technical field
The utility model relates to the extinguishing device field, particularly relates to a kind of power-actuated auto-rotating spray head that do not need.
Background technology
Present most of fire extinguisher shower nozzle all can not rotate, and simple plaing a part sprayed.The scope of such fire extinguishing device jet is fixed, comprehensive spraying fire-extinguishing agent, fire extinguishing weak effect.A spot of rotary fire extinguisher shower nozzle is arranged on the market, and its cardinal principle is on the basis of common shower nozzle, adds bearing arrangement and electro-motor, and shower nozzle is rotated by bearing arrangement under the drive of motor.The rotary nozzle of this electrical motor driven, use expense electricity, and complex structure poor practicability.Especially, when breaking out of fire, after opening extinguishing device, also need to open again the electro-motor on the rotary nozzle, because the limitation of motor, the shower nozzle rotating speed is relatively slow, and many procedures can increase the fault rate of fire extinguishing system and lose time, fire extinguishing procedure is seized every minute and second, and wastes a second more and endangers with regard to bull point.
The utility model content
The purpose of this utility model is the deficiency that solves above-mentioned technology, provides a kind of and can utilize the extinguishing chemical pressure shower nozzle of rotation automatically, and it does not need driven by power, and rotary speed is fast, spraying range is wide.
The technical solution adopted in the utility model:
A kind of auto-rotating spray head, it comprises churning module, centrifugal wheel and pedestal assembly, described churning module is fixed in the axle side of centrifugal wheel, described centrifugal wheel be axially arranged with blind hole, be fixed with the pedestal assembly in the described blind hole, the inner cone locator is equipped with in described centrifugal wheel bottom, described centrifugal wheel radially be provided with through hole, described through hole one termination is led to described axial blind hole, and its other end is towards the inclined-plane of described churning module.
Further, described centrifugal wheel is made of copper.
Further, the affixed mode of described churning module and centrifugal wheel is affixed by screw.
Further, described churning module is four.
Further, described pedestal assembly comprises a core and axle sleeve, described axle core hollow, and axle core front end is taper, its taper one end is fixed in the blind hole of described centrifugal wheel, the inner cone matched in clearance of its tapered front end and described inner cone locator; The described axle core other end is set with axle sleeve, between described axle core and the axle sleeve ball is housed.
Further, described axle sleeve end is provided with interface.
Further, the terminal outer wall of described axle sleeve is provided with external screw thread.
Adopt technique scheme, technique effect of the present utility model has:
When 1, the utility model uses, can the rotary-jet extinguishing chemical, spraying range is wide, good extinguishing effect.
2, the utility model does not need equipment such as electro-motor, and is simple in structure, long service life, and the operation during use is few, saves time.
3, the utility model does not need driven by power, utilizes the pressure of extinguishing chemical, rotation automatically, and power saving and rotary speed are fast.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is structure master's diagrammatic sketch of the utility model embodiment 1;
Accompanying drawing 2 is that A of the present utility model is to cutaway view;
Accompanying drawing 3 is structure master's diagrammatic sketch of the utility model embodiment 2;
Wherein: 1 churning module, 11 inclined-planes, 2 centrifugal wheels, 21 blind holes, 22 through holes, 3 pedestal assemblies, 31 cores, 32 axle sleeves, 321 interfaces, 322 external screw threads, 4 inner cone locators, 41 inner cones.
The specific embodiment
Wherein, described centrifugal wheel 2 is made of copper.Churning module 1 is affixed by screw with centrifugal wheel 2.Churning module 1 is four, arranges in the same way along centrifugal wheel 2 circumferencial directions, and leaves the gap between the churning module 1.
In use, the interface 321 of axle sleeve 32 ends is received on the extinguishing chemical pipeline of fire extinguishing system.During fire extinguishing, open fire extinguishing system, the high-pressure extinction agent is sent in a core 31 chambeies by interface 321 by pipeline, be injected in the chamber of centrifugal wheel 2 from the port of the tapered front end of axle core 31, the high-pressure extinction agent of chamber inner accumulated is ejected by the through hole 22 of centrifugal wheel 2, the extinguishing chemical of Pen Sheing is sprayed onto on the inclined-plane 11 of churning module 1 rapidly, is sprayed out by the gap between the churning module 1 then, implements fire extinguishing.The extinguishing chemical of Pen Sheing produces thrust to the inclined-plane 11 of churning module 1 rapidly, promotes churning module 1 a drive centrifugal wheel 2 and an axle core 31 and rotates together, reaches the effect of rotary-jet extinguishing chemical, and the fire extinguishing effect is splendid.
In addition, the ball 33 between axle core 31 and axle sleeve 32 can effectively be accelerated rotary speed.Through test, during the utility model work, its rotating speed can reach 1200 rev/mins.
The auto-rotating spray head that the utility model provides, simple in structure, rotary speed is fast, and spray effect is good.Not only can be used for fire extinguishing system, can also be applied to view and admire or irrigate in the water injection system of usefulness, it has wide range of applications.
It should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
