c. conveying the storage tube 01 to a preset position through a connecting section;
d. the regulating and blocking part releases the emulsion explosive 001 out of the storage pipe 01;
e. the storage tube 01 is taken out through the connection section.
As shown in the figure, the gas source control flow chart and the structure of the deepwater hole emulsion explosive 001 release device in the scheme are as follows; firstly, filling the emulsion explosive 001 into a storage tube 01, opening a gate valve to adjust a hand-pulling valve to one side of a blocking ring 03, opening an air source at the moment to form a passage between the air source and the blocking ring 03, inflating the blocking ring 03, and simultaneously, as an overflow valve b is connected to the blocking ring 03, overflowing the overflow valve b after the air pressure reaches the set pressure of the blocking ring, so that the blocking ring 03 is in a continuous pressure-maintaining inflation state, and at the moment, the emulsion explosive 001 is limited in a storage cavity; closing the gate valve and adjusting the hand-pulled valve to one side of the multistage cylinder 05, and then conveying the storage tube 01 filled with the emulsion explosive 001 to a preset position of the blast hole through the connecting section; after the conveying is finished, a gate valve is opened, so that a passage is formed between an air source and the multistage cylinder 05, the stop ring 03 can adjust the threshold value of the overflow valve b through the air passage of the multistage cylinder 05 at the moment, the threshold value of the overflow valve b is adjusted to be in a conventional state through the pressure in the multistage cylinder 05, namely, the emulsion explosive 001 is placed in an uninflated state of the storage cavity, at the moment, the air source drives the multistage cylinder 05 to push the emulsion explosive 001 out of the storage tube 01, the storage tube is lifted upwards while the emulsion explosive is released, the storage tube is prevented from being clamped in a blast hole, and the fixed-point placement of the emulsion explosive 001 is finished; and finally, taking out the storage pipe 01 which is completely released through the connecting section, wherein the air source is used for carrying out pressure protection on the whole structure through an overflow valve a, adjusting air pressure through a throttle valve and adjusting the pressure provided by the air source to a release section (a part participating in emulsion explosive release in a deep water hole in the emulsion explosive release device under the well), so that the phenomenon that excessive pressure enters the end of the release section, and the bubble is turned over and gushed when the emulsion explosive is released due to excessive air pressure to cause the change of the mud density at the bottom of the well and possibly cause the subsequent floating of the emulsion explosive out of the water surface is avoided. The whole structure is completely driven pneumatically, and the structure is simple and compact, so that the emulsion explosive 001 can be suitable for fixed-point blasting under extreme conditions, the application precision of the emulsion explosive 001 can be improved, the materials are saved, the blasting is complete, and the blasting safety and the blasting completion degree are ensured; and (3) an inflation process: opening the gate valve, keeping the valve core of the hand-pulled valve at one side of the stop ring, and closing the gate valve after the inflation is finished; the explosive pushing process comprises the following steps: the hand-pulled valve is kept at the side of the multistage cylinder, the gate valve is opened, and after the throwing is finished, the gate valve is closed; the scheme adopts a pneumatic control mode, so that the operation safety can be improved, the accuracy of putting the emulsion explosive can be improved, the accurate control of the dosage of the emulsion explosive can be realized, and the emulsion explosive can be placed at a fixed point.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
