In order to achieve the purpose, the invention adopts the following technical scheme.
The invention provides a remote detonation initiating device for underwater blasting, which comprises a detonation transfer cartridge and is characterized in that: the one end of booster cartridge case has the external screw thread of being connected with warhead cooperation, the other end of booster cartridge case is provided with the internal thread through-hole, can dismantle with the one end of booster fuse subassembly and be connected, the booster fuse subassembly includes booster fuse, booster cartridge case connector and detonator connector, the booster fuse with booster cartridge case connector fixed connection in proper order, the one end of booster cartridge case connector is provided with the external screw thread, with the connection can be dismantled to the internal thread through-hole of booster cartridge case, the one end of detonator connector is provided with the internal thread through-hole, can dismantle and be connected with the booster pipe subassembly, the booster pipe subassembly includes booster sleeve and booster, the telescopic one end of booster pipe is provided with the external screw thread, with the connection can be dismantled to the booster cartridge case connector, the telescopic other end of booster pipe with booster pipe fixed connection, the booster pipe subassembly the booster fuse subassembly with the booster cartridge case is hollow structure.
Preferably, the booster explosive cartridge is provided with two internal thread through holes at one end connected with the detonating cord component, and the two internal thread through holes are connected with the detonating cord component.
Preferably, the detonating tube sleeve is fixedly connected with one end of the detonating tube in a pinch printing mode.
The invention has the beneficial effects.
The invention is composed of three independent initiating explosive devices, can be connected in sections when an underwater test is carried out, is convenient to install and simple to operate, can realize blasting on the shore far away from a warhead, improves the safety and the detonation reliability of operators, all the parts are non-initiating explosive devices, and are mechanically connected with each other and the warhead, so that the safety of the operators during the test is improved.

In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration only.
FIG. 1 is an overall schematic view of the invention after joining.
Fig. 2 is a cross-sectional view of the booster cartridge of the present invention.
Fig. 3 is a sectional view of the explosion wire assembly of the present invention.
Fig. 4 is a cross-sectional view of the detonator assembly of the present invention.
The labels in the figure are: 1 is a booster cartridge, 2 is a detonating cord component, 3 is a detonating cord, 4 is a connector of the booster cartridge, 5 is a connector of the detonating tube, 6 is a sleeve of the detonating tube, 7 is the detonating tube, and 8 is the detonating tube component.
Detailed Description
Combine the figure to show, including passing and exploding cartridge case 1, the one end of passing and exploding cartridge case 1 has the external screw thread of being connected with the cooperation of warhead for connect warhead and come direct detonation warhead, the other end of passing and exploding cartridge case 1 is provided with two internal thread through-holes, every internal thread hole is used for can dismantling with an explosive fuse subassembly 2 and be connected, guarantee like this that can double-circuit redundancy, if the in-process of leading to exploding because the interference leads to under the unable circumstances of detonating all the way, can need not to install again and directly explode another way, can be safer to the blasting personnel. The detonating cord assembly 2 is used for conducting detonating, length is formulated according to the depth of warhead under water, guarantee that the one end of detonating cord assembly 2 is under water, the other end is on water, the outer wall thickness and the material of detonating cord assembly 2 can guarantee to reach insensitive nature and can not break at the in-process of firing the gunpowder conduction, detonating cord assembly 2 includes detonating cord 3, detonating cartridge case connector 4 and detonating tube connector 5, detonating cord 3 both ends can't be connected with detonating cartridge case 1 and detonating tube sleeve 6 alone, therefore need both ends to be fixed connection again and connect detonating cartridge case connector 4 and detonating tube connector 5, detonating cord 3 and detonating cartridge case detonating connector 4 are fixed connection in proper order, the one end of detonating cartridge case connector 4 is provided with the external screw thread, can dismantle with the through-hole of detonating cartridge case 1 and connect, the one end of detonating tube connector 5 is provided with the internal screw thread through-hole through-free connecting pipe connector 7, the detonating cord assembly 8 is realized the hollow detonating tube assembly that the detonating cord sleeve 6 and the detonating cartridge case can all inlay the detonating tube connector 7 and the other end and the detonating tube can dismantle and connect the other end and make the detonating tube assembly more firmly in a non-hole-piercing tube connecting mode.
