Underwater blasting priming device and use method

Abstract

The invention discloses an underwater blasting priming device. The underwater blasting priming device comprises an outer sleeve, an inner sleeve and a detonator shell, wherein the inner sleeve is installed in the outer sleeve; a soft metal buffer plate is fixedly installed in the inner sleeve; a rigid metal frame is embedded in the soft metal buffer plate and connected with a firing pin through aconnecting rod; a safety pin is transversely inserted in the outer sleeve and penetrates through the firing pin; the firing pin is sleeved with a firing pin spring; the detonator shell is connected with the outer sleeve through threads; a rubber ring is installed in the outer sleeve and provided with a waterproof film, and a percussion cap is arranged under the waterproof film. According to the underwater blasting priming device, the ignition time of the device is mastered by controlling the firing pin, and with the cooperative use of an electric detonator, the whole device is good in waterproofness, easy to operate, high in safety and greatly improved in efficiency.

Description

technical field [0001] The invention relates to an underwater blasting initiation device and a use method thereof, which belong to the field of blasting. Background technique [0002] The earth is divided into three parts land and seven parts ocean. In the past, due to shipbuilding, navigation technology, feudal concepts and other reasons, the ocean restricted human communication and economic development. Due to the continuous development of various aspects in the later period, the importance of the ocean has been continuously recognized by people, and people's sea activities have become more and more frequent, but they are also facing many problems. For civil aviation, reefs and some historical accumulations in the sea will hinder navigation, and for artificial obstacles, the existence of some explosive obstacles and non-explosive obstacles will hinder normal operations. The traditional method of removing obstacles is mechanical excavation or explosion destruction. For und...

For civil aviation, reefs and some historical accumulations in the sea will hinder navigation, and for artificial obstacles, the existence of some explosive obstacles and non-explosive obstacles will hinder normal operations

The traditional method of removing obstacles is mechanical excavation or explosion destruction. For underwater explosions, how to detonate the charge is a difficult problem. The ordinary ignition device is subjected to simple waterproof treatment for underwater use. The low level obviously cannot meet the needs. There are potential safety hazards in the use of electric detonators in an environment with water. After the fuse is ignited on the water surface, it can burn underwater, but the effect will be affected by long-term soaking in water, and the operation is inconvenient. The traditional method is inefficient. life safety is not guaranteed
