Further, storage ammonium nitrate and nitroguanidine in the propellant case, the igniter use electronics point
Duration and degree of heating, the igniter is by the way that on the controller on connection to ground, the route is drawn by carbon fibre inner lining pipe
Device out.
Further, three concave support seats are equally spaced in return water inner tube periphery.
Further, the sealing gasbag outer surface is coated with anti-corrosion material coating.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Igniter pilot gas propellant is started by ground controller in the utility model and generates inert gas to sealing
Air bag carries out filling rapidly and squeezes drilling, achievees the effect that obstruction, more preferable using sealing airbag structure blockage effect, can be effective
Reduce the not tight situation of sealing；It can be with using the fixed sealing air bag of fixing piece and concave support holder structure, after sealing air bag use
It is individually replaced, easy disassembly；The multiple supports for cooperating it internal using connection dish structure and limiting component, may be implemented to water outlet
The fixation limit effect of pipe and return pipe, extends the service life of device；By using carbon fibre inner lining pipe, sealing ring and antirust
The rustproof property in device with water or mud contacts component can be improved in the structures such as corrosion material coating, and then it is whole to improve device
The service life and experiment work quality of body.
