Timing invalidation control device of hypocenter bomb

Abstract

The invention discloses a timing invalidation control device of a hypocenter bomb, which comprises an outer barrel and an explosive arranged at the bottom of an inner cavity of the outer barrel. The upper part of the inner cavity of the outer barrel is provided with a cylinder for placing a detonator; a cylinder conical pipe is further distributed parallel to a cylinder pipe at the upper part of the inner cavity of the outer barrel; the lower part of an inner cavity of the cylinder conical pipe is filled with an invalidation control liquid; further, the inner wall of the cylinder conical pipe is provided with a limiting ring which is arranged below the liquid level of the invalidation control liquid; an I-shaped component is arranged in the inner cavity of the cylinder conical pipe and is further positioned above the liquid level of the invalidation control liquid; the pipe wall of the cylinder conical pipe at the outer side of the I-shaped component is provided with a communicating hole; the upper end of the I-shaped component is in overlap joint with an outer cover of the cylinder conical pipe; a liquid-absorbing expanding material is filled between the upper end of the I-shaped component and the outer cover of the cylinder conical pipe; the I-shaped component is sealed with the cylinder conical pipe through an O-shaped sealing ring; and the top wall of the outer barrel is sealed through the outer cover. By using the timing invalidation control device of the hypocenter bomb, the sealing state of a shell of the hypocenter bomb can be effectively maintained; the explosion function of the hypocenter bomb is guaranteed; and under the condition that a dud bomb appears, the invalidation time of the hypocenter bomb can be controlled in a timing way.

Description

technical field [0001] The invention relates to the failure control of seismic source bombs used in geological exploration and oilfield survey, in particular to a timed failure control device for seismic source bombs. Background technique [0002] Seismic bombs are widely used in geological exploration and oilfield surveying. Its main structure is to assemble a certain quality of high-energy explosives in a sealed container of a specific shape. Under the excitation of strong light, strong heat, or electromagnetic waves, the explosives are detonated through a detonator. Generates high energy and vibration waves. With the help of specific analysis methods, the generated energy and vibration waves are analyzed to judge the geological conditions and oilfield conditions, and provide reliable data for geological exploration and oilfield exploration. important position and role. However, due to accidental uncontrollable factors in the links of production, assembly, transportation...

Problems solved by technology

[0003] The traditional method of removing dud bombs is engineering excavation, that is, after positioning the unexploded dud bombs through GPS technology, engineers dig out the dud bombs buried in the ground by digging. The main disadvantages of this method are two : First, there are potential safety hazards in the excavation process. Improper construction methods may detonate dud bombs, causing casualties; second, excavation affects the construction progress, resulting in an increase in project cost

The main disadvantages are: first, the electrical signal of the detonator Bunsen interferes with the safe detonation of the seismic source bomb, which improves the technical requirements for the detonation of the seismic source bomb; second, the production, installation, transportation and use of the detonator are very strict, which will also increase The overall cost of the source bomb; the third is that when the detonator is detonated, the dud bomb may be detonated, causing a safety accident
