Utility model content
The technical problems to be solved in the utility model is to provide a kind of exploration focus, can solve the deficiencies in the prior art, by the advantage of hammering focus and hypocenter of the explosion is merged, the high-energy driving weight that utilizes blast to produce, can obtain high-octane hammering elastic wave, simple in structure, be easy to carry and install.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
An exploration focus, structure comprises powder charge steel drum, in the side of powder charge steel drum, is provided with powder charge hole, and powder charge hole arranged outside has enclosing cover, covers outward and is provided with detonator lead-in wire, and enclosing cover is fixed on powder charge steel drum by steel nail; The lower end of powder charge steel drum is provided with lower heavy punch, and the bottom of lower heavy punch is provided with elastic support, weight in the middle of the upper end of powder charge steel drum is provided with, and the top of middle weight is hinged with lever, and lever is movably arranged on support, at the other end of lever, is fixed with weight; On the scope of attack of lower heavy punch and upper weight, be provided with backing plate.
As preferably, the top of described support is hinged with fastener, is provided with snap close on fastener, and described lever is fixed in fastener.
As preferably, between described lower heavy punch and middle weight and the inwall of described powder charge steel drum, be provided with high-temperature resistant seal ring.
As preferably, described elastic support is spring.
As preferably, the upper surface of described backing plate is plane, and lower surface is the arcwall face of protrusion of surface upwards, and the engagement edge of upper surface and lower surface is keen edge.
As preferably, in described powder charge steel drum, filling is emulsion [explosive.
The beneficial effect that adopts technique scheme to bring is: the high energy impact events ripple that the Lithium Oxides By Detonation With Emulsion Explosive of the utility model utilization in powder charge steel drum produces promotes lower heavy punch and middle weight, and by lever, expulsive force is passed to upper weight, make weight and lower heavy punch to ground, carry out hammering by backing plate, produce elastic wave.Upper weight and lower heavy punch can make full use of the explosion time shock wave that both direction discharges up and down, and the high-temperature resistant seal ring arranging between lower heavy punch and middle weight and powder charge inner walls of steel drums can reduce scattering and disappearing of explosion wave, improves hammering energy.By adjusting the position of lever on fastener, can control strength and the speed of weight hammering.Backing plate is conducive to underground medium transmission compressional wave vertically downward, and backing plate edge is relatively little to the caused tangential vibrations of tangential effect of dielectric surface, has reduced the interference to exploration of surface wave and horizontal shear wave.Emulsion [explosive has the advantages that density is high, explosion velocity is large, brisance is high, water repelling property is good, critical diameter is little, sensitivity to initiation is good, safe and reliable.
