Abstract

The invention provides a large-energy intelligent vibroseis. The intelligent vibroseis comprises a combustion chamber connected with a fuel gas source and an auxiliary fuel gas source. An emission pipe is connected with an exit end of the combustion chamber. An emission ball is arranged in the emission pipe. A limiting device is arranged on the emission pipe and is capable of permitting the emission ball to pass when the stress is larger than a set value and clamping the emission ball in a to-be-emitted position when the stress is smaller than the set value. When the emission ball is in the to-be-emitted position, the emission ball and the combustion chamber are enclosed to form a closed space. The beneficial effects are that in use, the vibroseis can be reversely arranged rapidly so that the emission ball is enabled to impose the force larger than the set value on the limiting device under the effect of the inertia force, so the emission ball can be rapidly remitted out by the energy of gas flows, thereby finishing energy motivation once. According to the invention, the emission ball can be used as a medium for energy transmission, so movitation strength can be increased and motivation effects are improved.

Description

technical field [0001] The invention relates to a large-energy intelligent vibrator. Background technique [0002] In the fields of engineering geological survey, resource exploration, and engineering quality inspection, shallow seismic reflection method, shallow seismic refraction method, vertical reflection method, etc. are commonly used geophysical methods. Artificial seismic sources are indispensable professional equipment in the process of carrying out these methods, and are mainly used for the excitation of elastic waves. Commonly used traditional artificial sources mainly include explosives, hammers, electric sparks, etc. Explosive sources generally use TNT explosives, detonators, etc. Due to the particularity of materials, professional and technical personnel are required to purchase, transport, and operate, which is dangerous and limited in scope of application. [0003] The hammer source is the simplest artificial source and consists of a hammer and an iron chopp...
