Description
Technical field
The utility model relates to the self-extinguishing equipment that fire-fighting is used, particularly a kind of nozzle of automatic track and localization jet extinguishing water cannon.
Background technology
For the life of protecting people and the safety of property, fire-extinguishing apparatus or equipment are indispensable necessary facilities in work or public place.
In early days, when fire takes place, seldom having can automatically actuated fire extinguisher, after being it is found that, majority finishes fire extinguishing by the manually-operated fire extinguisher again, owing to be it is found that also needed a period of time that when fire occurs to if can not extinguish the blaze in time in bud in the short period of time, in a single day the intensity of a fire spreads, uncontrollable probably, finally lead to heavy losses.As seen, when fire just took place, it was vital at once it being put out.
Along with improving constantly of science and technology, people have developed many detection of fires automatically, and automatically actuated extinguishing water cannon, these extinguishing water cannons are because can be when fire takes place, the position of flame is scanned the rotating mechanism rotation of locating and controlling nozzle by scanning system by scanning system, make nozzle alignment flame and ejecting extinguishing material, thereby generally used by people institute.
But there is a problem in common extinguishing water cannon, and is big from the jet scattering that its nozzle ejection goes out exactly, and water column is concentrated inadequately, thus when equal operating pressure nearer, the jet of the range of water column to land downforce less, thereby the fire extinguishing effect is not good enough.The extinguishing water cannon that has is set up bifurcation type cross section flow deflector in nozzle, nozzle is divided into three inner chambers.But the jet that this nozzle penetrates is divided into three pinches, though improve to some extent to increasing the jet range, but still have that the jet forward momentum is not enough, jet lands the downforce problem of smaller.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of nozzle of automatic track and localization jet extinguishing water cannon simple in structure is provided, and the current of injection is concentrated, far firing range, downforce be big, also can effectively shorten nozzle length simultaneously.
For reaching above-mentioned purpose, the utility model by the following technical solutions: this is the nozzle of track and localization jet extinguishing water cannon automatically, comprises blast tube, and described blast tube inner chamber is followed successively by diversion section, accelerating sections and advection section from the inside to surface; A plurality of flow deflectors that radially are arranged at inside pipe wall are arranged in the diversion section, and accelerating sections is the conical section that bore diminishes gradually, and the advection section is the straight length that diameter equates with the accelerating sections minor diameter.
As a kind of improvement, described flow deflector be 3 or more than, be preferably 6, and be distributed in the diversion section; Arbitrary flow deflector is trapezoidal or approximate trapezoid, and the trapezoidal narrow end is positioned at the diversion section entrance point, and the wide end is positioned at the diversion section port of export; Described flow deflector is that approximate right angle is trapezoidal, and trapezoidal approximate right angle waist is fixed on the diversion section inwall, and the oblique angle waist also can be revised as streamlined.
As further improving, the diameter of the entrance point of described accelerating sections is not less than the diameter of wall outlet in the diversion section.
As further improving, the length of described diversion section and accelerating sections is roughly suitable; The length of advection section be 4 times of advection section internal diameter or more than.
The utility model has following advantage and effect with respect to prior art: (1) is because blast tube of the present utility model is divided into diversion section from import successively to outlet, accelerating sections and advection section, and a plurality of flow deflectors that radially are arranged at inside pipe wall are arranged in diversion section, under the effect of flow deflector, current are through behind the flow deflector, its turbulent flow and eddy flow are effectively suppressed and are converted into axial kinetic energy, the axial velocity of current is improved, at this moment current are at the process accelerating sections, because accelerating sections is the conical section that bore diminishes gradually, further promote the speed of current, thereby increased the range of current; (2) water column that ejects of the utility model is concentrated, and far firing range, the downforce of landing are big, good extinguishing effect; (3) simple in structure, be convenient to processing and manufacturing, help applying of market.

Fig. 1 is the nozzle cross-sectional schematic of automatic track and localization jet extinguishing water cannon of the present utility model;
Fig. 2 is the cross section cross-sectional schematic of diversion section among Fig. 1.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As Fig. 1～shown in Figure 2, the nozzle of automatic track and localization jet extinguishing water cannon of the present utility model, comprise blast tube 1, blast tube 1 inner chamber is followed successively by diversion section 2, accelerating sections 3 and advection section 4 from the import to the outlet, a plurality of flow deflectors 21 that radially are arranged at inside pipe wall are arranged in diversion section 2, the conical section that described accelerating sections 3 diminishes gradually for bore, described advection section 4 is a straight length, the diameter of this straight length and the minor diameter of accelerating sections are about equally.
Described flow deflector 21 adopt 3 or more than, general optional 6, being circumference is distributed in the diversion section on 2 the inboard wall of tube body symmetrically and evenly, certainly, the quantity of flow deflector 21 can be determined suitable quantity according to actual needs, also can adopt unsymmetric form to distribute, the quantity of flow deflector 21 can be even number, also can be odd number; The shape of each flow deflector 21 can be trapezoidal, as is right-angled trapezium, also can be approximate trapezoid, be deformed into streamlined limit as trapezoidal oblique angle waist, trapezoidal approximate right angle waist is fixed on diversion section 2 inwalls, and the trapezoidal narrow end can be positioned at the diversion section entrance point, and the wide end can be positioned at the diversion section port of export.
