Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The structural representation of one embodiment of the air bubble of using for the utility model hail impulse test as shown in Figure 1.In the present embodiment, the air bubble that hail impulse test is used comprises: gun tube 1 and hold the hopper 2 of the particle that hail impulse test uses, the rear end of gun tube 1 is communicated with high-pressure air source, hopper 2 is arranged on the top of gun tube 1, the bottom of hopper 2 is communicated with gun tube 1, drops under the effect of particle in gun tube 1 gases at high pressure in gun tube 1 and penetrate from the front end of gun tube 1 from hopper 2.Respectively right side part and the left part of gun tube in corresponding Fig. 1 of the front-end and back-end of gun tube 1 herein.
In the present embodiment, the hopper that holds the particle that hail impulse test uses is arranged on the top of the gun tube that connects high-pressure air source, in gun tube, pass through pressure-air, under the ejector action of high-speed gas, particle in the hopper of gun tube top is constantly inhaled in gun tube, is drawn under the effect of particle in the gun tube gases at high pressure in gun tube and outwards penetrates from the front end of gun tube.Than the particle radiation pattern of existing ejection type, this particle radiation pattern based on injection principle is without carry out manually shooting one by one as existing ejection type particle radiation pattern, along with the particle in hopper reduces gradually, can in hopper, continue to add particle, guarantee that hopper endoparticle thing is drawn into process in gun tube uninterrupted, and then realize the continuous transmitting of particle.
This air bubble can support one or more hoppers that providing of particle is provided, the corresponding transmitting that also can realize the particle of difformity or size, wherein the hopper in the embodiment shown in Fig. 1 is single hopper, can the single shape of splendid attire or the particle of size, also can splendid attire various shape or the particle of size.And Fig. 2 embodiment has comprised multiple hoppers, be respectively hopper 21 and hopper 22, in these two hoppers, can hold respectively difformity that hail impulse test uses or the particle of size, for example hopper 21 holds the hail of large-size, and hopper 22 holds the ice pellets of reduced size etc.
In order to control the discharge of hopper endoparticle thing, can utilize hopper valve to control, as shown in Figure 3, the structural representation of the another embodiment of the air bubble of using for the utility model hail impulse test.Compared with a upper embodiment, the present embodiment is provided with hopper valve 31 in the bottom of hopper 21, in the bottom of hopper 22, hopper valve 32 is set, by the regulation of hopper valve 31 and 32, can realize the adjusting of the uninterrupted of the particle in hopper 21 and 22, and then control the blending ratio of variable grain thing.Rear end at gun tube 1 can arrange gas source valve 4, by gas source valve 4 open or close realize the unlatching of air bubble or close.In another embodiment, also can consider gas source valve to carry out step unlatching, so just can realize the pulsed of particle and spray.
For air bubble, when adopt ice pellets to use as hail impulse test particle time, during transmitting, easily condense on gun tube inwall, gun tube is stopped up, and then affects the normal use of air bubble.So, by increase heating mechanism on gun tube, gun tube is carried out to preheating, just can effectively suppress this ice pellets phenomenon of condensing, as shown in Figure 4, in the air bubble embodiment using for the utility model hail impulse test with the gun tube structural representation of the mechanism of generating heat.As we can see from the figure, when particle is ice pellets or hail, the heating mechanism 6 that gun tube 1 temperature is improved can be set at the front end of gun tube 1.Heating mechanism preferably adopts resistance wire, is convenient to be wrapped on gun tube outer wall.According to specific circumstances, can also be further at the coated insulation material of front end of gun tube, for example asbestos, sponge or foam, to avoid the rapid decline of gun tube temperature.
Fig. 5 shows the application schematic diagram of an embodiment again of the air bubble that the utility model hail impulse test uses.In the present embodiment, on gun tube 1, be coated heating mechanism 6, and provide pressure-air by high pressure gas holder 5, in hopper 21 and 22 respectively splendid attire the ice pellets of large-size and the ice pellets of reduced size.Based on this embodiment, below in conjunction with engine, inhale hail and test the function that air bubble that the utility model hail impulse test is used realizes and describe:
First connect electro-heat equipment 6, give gun tube 1 preheating, close bunker gate 31 and 32, the graininess missile of annotating in hopper 21 and 22 (claim afterwards missile, above indication particle), inflates then to high pressure gas holder 5, reaches certain air pressure; Open gas source valve 4, gases at high pressure enter gun tube 1 with certain speed; Open bunker gate 31 and 32, under the ejector action of gun tube 1 high speed gas, the missile in hopper 31 and 32 is inhaled into gun tube 1, and missile accelerates to penetrate gun tube 1 under the effect of gun tube 1 high speed air-flow.
In the process of transmitting, by constantly supplementing source of the gas to high pressure gas holder, and supplement missile in hopper, can realize continuous transmitting.In the process of transmitting, can regulate the aperture of bunker gate, can realize the adjustment of the flow of missile and the ratio of different hopper missiles, in addition, in the process of transmitting, can open gas source valve by batch (-type), realize pulsed transmitting missile.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
