Specific implementation mode
Below in conjunction with the drawings and the specific embodiments, the present invention will be described：
As shown in Figs. 1-2:A kind of high pressure light-gas gun emitter of adjustable immersion angle degree, including air accumulator 1 and with 1 phase of air accumulator
The trigger mechanism of connection；Trigger mechanism includes telescoping support frame 10 and light-gas gun transmitting tube 9, and wherein telescoping support frame 10 has
Body is the frame structure built by telescoping mechanism, and the bullet mouth end that goes out of light-gas gun transmitting tube 9 is placed in downwards telescoping support frame
In 10, goes out bullet mouth end and gun muzzle buffer 12 is installed, tracheae adapter 7 is nested and fixed in the loading port end of light-gas gun transmitting tube 9；
Wherein, tracheae adapter 7 includes upper converting interface, lower converting interface and side converting interface；For the recoil for offsetting when light-gas gun transmitting
Effect, anti-locking apparatus generates big vibration, is equipped with beam 8 at the lower converting interface end of tracheae adapter 7, the beam 8 is solid
Due to the top of telescoping support frame 10.The upper converting interface end of tracheae adapter 7 is fixed with spring pipeline buffer 6 and is used for subtracting
The vibration of weak device, prevents structure from being destroyed.Tracheae adapter 7 is coaxially fixed at the loading port end of light-gas gun transmitting tube 9
Upper converting interface end；Between air accumulator 1 and side converting interface be equipped be sequentially connected combination appendix 2, pneumatic flanged ball valve 4 and
Connection flexible pipe 5 is preferably screwed together by flange between combination appendix 2, pneumatic flanged ball valve 4 and connection flexible pipe 5；Connection
It is connected by flange 3 between hose 5 and side converting interface；It includes that interconnected multistage cross section is identical to combine appendix 2
Rigid connection pipe.
Light-gas gun transmitting tube 9 go out bullet mouth end equipped with laser velocimeter with measure injection bullet 16 it is initial when entering water
Speed；Laser velocimeter includes laser emitter 17 and laser pickoff 18, and laser emitter 17 and laser pickoff 18 are distinguished
It is located at the both sides below bullet mouth end（As seen in figs. 5-6）.
As shown in Figure 1, the bullet mouth end that goes out in light-gas gun transmitting tube 9 is equipped with rail plate, wherein Fig. 3 shows light-gas gun
The connection structure of transmitting tube 9 and rail plate：Rail plate includes fixation guide rail 11a arranged in parallel and is mutually parallel
Moving guide rail 11b, moving guide rail 11b are perpendicular to fixed guide rail 11a and are slidably connected on fixed guide rail 11a；Fixed guide rail 11a
It is fixed on telescoping support frame 10, light-gas gun transmitting tube 9 is located between moving guide rail 11b, and makes moving guide rail 11b and side
The axis of square converting interface is parallel.
Due to being connected by flange 3 between combination appendix 2 and side converting interface, it is sent out when needing adjusting light-gas gun
When penetrating the angle for going out bullet mouth end of pipe 9, it is only necessary to, will after flange 3 releases fastening between combination appendix 2 and side converting interface
Light-gas gun transmitting tube 9 go out bullet mouth end be adjusted under predetermined angle, then the state will be in tracheae adapter 7 at the converting interface of side
Flange 3 re-secured together with the flange 3 for combining 2 end of appendix；That is light-gas gun transmitting tube 9 goes out bullet mouth end around side
Square converting interface（Or flange 3）Axis rotation, therefore moving guide rail 11b is set as parallel with the axis of side converting interface,
Moving guide rail 11b can be made with the rotation for going out bullet mouth end of light-gas gun transmitting tube 9 and slided on fixed guide rail 11a（Such as Fig. 4
It is shown）, firm effect is played to the bullet mouth end that goes out of light-gas gun transmitting tube 9, meanwhile, the setting of telescoping support frame 10 can root
It makes adjustment to the height of supporting rack according to the angle of inclination of light-gas gun transmitting tube 9, realizes the present invention under each design angle just
Often work.
As seen in figs. 5-6, the tube wall below the loading port end of light-gas gun transmitting tube 9 is equipped with multiple oblong through-holes
14, which is arranged along the tube body circumference of light-gas gun transmitting tube 9, preferably along the tube body circumference of light-gas gun transmitting tube 9
Upper and lower two circle oblongs through-hole 14 is set, and the gross area of oblong through-hole 14 is made to be more than the transversal of 9 tube body of light-gas gun transmitting tube
Area.Since the loading port end cap of light-gas gun transmitting tube 9 is connected in tracheae adapter 7, the just position of oblong through-hole 14
In tracheae adapter 7, the design of the oblong through-hole 14 on the tube wall below loading port end can make high pressure gas equal
Even entrance can steadily push bullet 16 to move, effectively prevent trigger mechanism amplitude excessive.
Equally, multiple oblong through-holes 15 also are provided on the tube wall of light-gas gun transmitting tube 9 gone out above bullet mouth end,
The oblong through-hole 15 is arranged along the tube body circumference of light-gas gun transmitting tube 9, is preferably arranged along the tube body circumference of light-gas gun transmitting tube 9
Upper and lower two circle oblongs through-hole 15.And the gross area for using the oblong through-hole 15 at bullet mouth end is more than 9 tube body of light-gas gun transmitting tube
Cross-sectional area.Going out the design of oblong through-hole 15 at bullet mouth end can play the role of that high pressure gas being discharged in advance, prevent height
Body of calming the anger reaches the water surface prior to bullet 16 and generates disturbance.
The application method of the present invention is as follows：
The telescoping support frame 10 of the present invention is fixed on by crossbeam 13 on experiment porch, and air accumulator 1 is welded on experiment
On platform.It first closes pneumatic flanged ball valve 4 and is passed through gas into air accumulator 1, it is real that progress is stopped at after reaching required air pressure
When testing, loading 16 first enables bullet 16 to stop the oblong through-hole 14 below loading port end, opens at this time pneumatic
Flanged ball valve 4, high pressure gas enter tracheae adapter 7, since the oblong through-hole 14 at loading port end at this time is blocked by bullet support 16b
Therefore high pressure gas cannot enter light-gas gun transmitting tube 9.At this time again by using low pressure at the loading port end of light-gas gun transmitting tube 9
Gas acts on bullet 16, and the two is made to start slowly to fall, when bullet 16 moves to 14 or less oblong through-hole, loading port
The oblong through-hole 14 at end is opened, and at this moment high pressure gas enters light-gas gun transmitting tube 9 from the oblong through-hole 14 at loading port end, and
Bullet 16 is pushed to accelerate.When by gun muzzle buffer 12 of 9 outlet end of light-gas gun transmitting tube, by the bullet support of bullet 16
16b and body 16a separation, bullet support 16b are stayed in light-gas gun transmitting tube 9, and body 16a can be projected due to inertia from gun muzzle.It can be excellent
Be selected in 16 bullet support 16b of bullet upper and lower ends respectively installation one rubber seal, and choose it is suitably sized, can obtain very well
Sealing effect, bullet 16 can be made by stiction to be maintained at oblong below loading port end in loading 16 logical
The position in hole 14.
The above content is combine specific optimal technical scheme it is made for the present invention be further described, and it cannot be said that
The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention's
Protection domain.
