Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of liquid-gas phase transition Explosive Ordnance Demolition device structure of gun barrel schematic diagram；It is made up of support 1, destruction device gun barrel 2, excitation power source 3；Described destruction device gun barrel 2 includes launching gun barrel 21, emission cavity 22, heater 23, letting out energy device 24 and connect the connection member 25 launching gun barrel with emission cavity, is provided with water blockoff plug 26 at ejecting gun pipe end；Described excitation power source 3 connects heater 23；Offer gas filling hole 27 on described emission cavity, and be correspondingly arranged on sealing-plug 28；Described letting out can be arranged on emission cavity 22 and launch gun barrel 21 junction by device 24；Described support 1 connects destroys device gun barrel 2.
In embodiment, excitation power source is mainly used in heater reliably, quickly heat, and can use Special vehicle-mounted power supply, portable power source or through frequency conversion, the mains lighting supply etc. of transformation.
It is the emission cavity in the present embodiment, heater and connection member structural representation as shown in Figure 2；There is at emission cavity emission cavity the inner chamber of a constant volume, fill liquid gas at inner chamber, excited by the external world and be easier to produce liquid-gas phase transformation, the class gas that volumetric expansion is bigger, liquid carbon dioxide can be used.Heater is mainly used in quickly heating liquid gas in device (liquid carbon dioxide).Heating devices heat principle can use electromagnetic induction heating, resistance heating (as liquid CO 2 is directly heated in emission cavity by " immersion heater " of the prior art) or microwave heating etc..Embodiment uses electromagnetic induction heating, the alternating current that excitation power source produces produces alternating magnetic field by induction apparatus (i.e. coil), magnetic conductivity object is placed in one and cuts alternate magnetic force line, thus the electric current (i.e. eddy current) of alternation is produced at interior of articles, eddy current makes the atom high speed random motion of interior of articles, atom collides with each other, rubs and produce heat energy, thus plays the effect of heating article (i.e. liquid gas).
Connection member be mainly used in emission cavity with launch gun barrel reliable, be quickly connected, screw thread can be used to screw, the form such as card open tightening connects.
Let out device effect before liquid gas excites to be to enter for barrier liquid gas to launch in gun barrel, when there is liquid-gas phase transition in liquid gas (liquid carbon dioxide) moment of quickly heating, volume rapid expanding, after pressure reaches certain certain value, let out and can open or rupture voluntarily by device, gases at high pressure moment releases, and enters and launches gun barrel and act on the built-in water body launching gun barrel.
Ejecting gun pipe is used for built-in water body, it is ensured that gases at high pressure reliable action is in water body and promotes water body to form high-speed water jet, penetrates and impacts target.The effect of water blockoff plug is stifled to seal water body at ejecting gun pipe end oral area plug.The water body launched in gun barrel can be placed in ejecting gun pipe by fill, it is possible to is prefabricated into cylindric being placed in mated with gun barrel and launches in gun barrel.
Fig. 3 is supporting structure schematic diagram.Support can be selected for the various ways such as "the" shape, triangle, with fixed transmission gun barrel and regulate transmitting gun barrel position, angle, it is simple to smoothly complete explosive or the disposing task of not clear suspicious object.A () figure is "the" shape support, (b) figure is triangular supports, and support and the connected mode destroying device gun barrel can select the movable connection methods such as bolt, bearing.
The workflow principle of this utility model liquid-gas phase transition Explosive Ordnance Demolition device is: excitation power source input → heater liquid gas (liquid carbon dioxide) quickly, in continuous heating → emission cavity is rapidly heated, its state generation Rapid Variable Design, form gases at high pressure → reach certain setting value, gases at high pressure from let out can release device moment → gases at high pressure promote water body to form high-speed water jet → water body to penetrate and impact target (" → " represent next step the meaning).
The using method of this utility model liquid-gas phase transition Explosive Ordnance Demolition device, including step:
(1) liquid carbon dioxide is added by filling aperture press fit into the inner chamber of emission cavity, and filling aperture is sealed；Add water to the inner chamber launching gun barrel, and by water blockoff plug, the ejecting gun mouth of pipe is blocked.Liquid gas fill before certain disposal task that carries out is complete, fill work uses " CO 2 high pressure gas cylinder-refrigerant pressure pump-metering aerating device " unit equipment such as to carry out fill by the gas filling hole on emission cavity, and fill is complete to be sealed by fit sealing device.When certain subtask that carries out can carry the emission cavity of the most canned multiple liquid gas simultaneously, in order to reuse.Gas filling hole and sealing-plug are as shown in Figure 2.
(2) described liquid-gas phase transition Explosive Ordnance Demolition device is launched position by Stent Implantation, and regulating transmitting gun barrel position and angle, fixed transmission gun barrel, aim at pending explosive；
(3) excitation power source is arranged on safety zone, and connects heater by laying wire road；
(4) controlling the switch Guan Bi of excitation power source, connect heater, built-in liquid carbon dioxide is rapidly heated, and forms gases at high pressure, promotes water body to form high-speed water jet from letting out to release device moment, hits pending explosive.After explosive is disposed, scene is checked and removes receipts and destroy device or arrange next Destruction.
As it is shown on figure 3, liquid-gas phase transition Explosive Ordnance Demolition device can be set to unidirectional gun barrel form；As shown in Figure 4, above-mentioned liquid-gas phase transition Explosive Ordnance Demolition device can be configured as two-way gun barrel form, so that the recoil phenomenon formed when the injection of high speed water body is reduced or eliminated (destroy device support and launch gun barrel when water body penetrates, overall can penetrate contrary direction along water body move or dish out certain distance).
Above-mentioned simply preferred embodiment of the present utility model; not this utility model is made any pro forma restriction; any those of ordinary skill in the art; in the case of without departing from technical solutions of the utility model scope; according to this utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should fall in the range of technical solutions of the utility model are protected.
