Water-proof double explosive-source explosive post

Abstract

The invention provides a waterproof dual-shock source grain column. It is composed of a charge shell and a sealing gland, and the sealing gland seals the explosive in the charge shell. The upper end of the charge shell is provided with a socket, and a convex ring is arranged on the inner wall of the shell below the socket. The sealing gland is combined with the convex ring through tight fit. A sealing ring is provided between the convex ring and the outer circle of the sealing gland. There is a perforation of the detonating thread at the lower end of the socket or above the sealing gland. The lower end of the socket is provided with a reduced-diameter socket, and the outer circle of the reduced-diameter socket coincides with the inner circle of the socket at the upper end of the adjacent powder shell, and is connected by a connecting locking device. The top of the socket is provided with an inner The detonation blind hole is concave, and the detonation hole on the top of the joint is opposite to the sealing gland in the adjacent charge shell. Compared with the prior art, the waterproof dual-source grain column has the characteristics of reasonable design, simple structure, water-resistant sealing, safe and reliable use, easy maintenance, etc., and is widely popularized and used, therefore, it has good promotion and use value.

Description

1. Technical field [0001] The invention relates to a production and processing technology of blasting equipment, in particular to a waterproof double-shock source charge column. 2. Background technology [0002] The deficiencies in the actual application of the plastic seismic source grains in the prior art are: complicated process, large consumption of raw materials, inconvenient use, poor water resistance and poor safety performance, etc. For example, the application number is No. 98211491.5, and the name is "Removable pressurized seismic source powder column". In addition to the troublesome connection through heat sealing, the cartridge filled with explosives uses an electric heater to heat and heat seal the gland, which itself has certain risks. In addition to increasing the raw material consumption of the connecting parts for the connection between the cartridges, the additional connecting parts will bring a lot of inconvenience to the user whether it is transportation...
