Abstract
The invention relates to a seismic focus used for seismic exploration, in particular to a mechanical seismic focus. The mechanical seismic focus comprises a hydraulic pump, a hydraulic cylinder, a spring, a hoisting release hook, a hammer, a chopping block and a guide pole, wherein the hydraulic pump is connected with the hydraulic cylinder; the hydraulic cylinder is fixed on an upper cover plate; the upper cover plate is connected with a lower soleplate through the guide pole; the upper cover plate is provided with a release lever; the spring is wound outside the hydraulic cylinder; the bottom end of the spring is connected with the upper cover plate, while the lower end of the spring is connected with the hammer; the top end of the hydraulic cylinder is connected with the upper end of the hoisting release hook through the spring; the lower end of the hoisting release hook is connected with the hammer; and the chopping block is hung outside the lower soleplate. The mechanical seismic focus has the following work flow: the hydraulic pump works to hoist the hydraulic cylinder, the hydraulic cylinder hoists the hammer through the hoisting release hook, while the spring on the hammer is compressed, an exciting key on the hoisting release hook is excited to release the hammer, and the hammer excites the chopping block to generate seismic waves. As the seismic waves are generated in a mechanical mode, the mechanical seismic focus can replace explosion seismic focus so as to ensure construction safety and no environment damage, and improve the efficiency of construction.
Description
Technical field
The present invention relates to a kind of mechanical source that the seismic prospecting industry is used that belongs to, relate in particular to and a kind ofly hydraulic cylinder is promoted by hydraulic pump works, hydraulic cylinder promotes tup by promoting release hook, simultaneously with the length of spring compressed on the tup, excite the burst key that promotes on the release hook that tup is discharged by release lever, tup excites chopping block to produce the mechanical source of seismic wave.
Background technology
The focus kind of seismic prospecting industry is a lot, and the big easy to operate small-sized single-impact focus of excitation energy is rare.What routine was used is explosive or man-made explosion, and the explosive explosive source is dangerous, and the man-made explosion energy is little.Mechanical source safety, energy is big and efficient is high, is specially adapted to URBAN EARTHQUAKE exploration and shallow seismic exploration.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of safety, energy novel mechanical focus big, easy to use, with low cost are provided.
The present invention for achieving the above object, by the following technical solutions: a kind of mechanical source, it is characterized in that, it comprises hydraulic pump, hydraulic cylinder, spring, promote release hook, tup, chopping block, guide pillar, described hydraulic pump connects hydraulic cylinder by hydraulic oil pipe, hydraulic cylinder is fixed on the upper cover plate, handle is connected with upper cover plate, upper cover plate is connected with lower shoe by guide pillar and is fastening, guide pillar passes the pilot hole on the tup, and upper cover plate is equipped with release lever, and hydraulic cylinder is surrounded with spring outward, the spring upper end is connected with upper cover plate, the spring lower end is connected with tup, and the hydraulic cylinder bottom is connected with the upper end that promotes release hook by spring, and the lower end that promotes release hook is connected with tup, described chopping block places the below of lower shoe, contacts with ground; Hydraulic cylinder promotes tup by promoting release hook, simultaneously with the length of spring compressed on the tup, after reaching the pressure of regulation, the work of stop solution press pump, by making release lever open release hook tup is discharged, tup moves downward under the positioning action of guide pillar and impacts chopping block generation high frequency artificially seismic wave.
Beneficial effect of the present invention: what routine was used is explosive or other non-explosive source, and the explosive explosive source is dangerous, and other non-explosive source energy is little.This mechanical source is safe in utilization, energy is big and efficient is high, is specially adapted to URBAN EARTHQUAKE exploration and shallow seismic exploration.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of mechanical source, be characterized in, it comprises hydraulic pump 16, hydraulic oil pipe 14, hydraulic cylinder 1, spring 3, promote release hook 4, tup 5, chopping block 7, guide pillar 9, connect hydraulic cylinder 1 by external hydraulic pump by hydraulic oil pipe, hydraulic cylinder 1 is fixed on the upper cover plate 11, handle 10 is connected with upper cover plate 11, upper cover plate 11 is connected with lower shoe 13 by guide pillar 9 and is fastening, and guide pillar 9 passes the pilot hole 15 on the tup 5, and tup 5 slides on guide pillar 9, upper cover plate 11 is equipped with release lever 2, be surrounded with spring 3 outside the hydraulic cylinder 1, spring 3 upper ends are connected with upper cover plate 11, and spring 3 lower ends are connected with tup 5, hydraulic cylinder 1 bottom is connected with the upper end that promotes release hook 4 by spring 3, the lower end that promotes release hook 4 is connected with tup 5, and described chopping block 7 places the below of lower shoe 13, contacts with ground.Described guide pillar 9 is equipped with outer cover 12, and outer cover 12 places on the lower shoe 13, is connected with trailing wheel 8 with front-wheel 6 respectively before the lower shoe 13.
Principle of work: primer fluid press pump 16 work, by hydraulic oil pipe 14 hydraulic cylinder 1 is promoted, hydraulic cylinder 1 promotes tup 5 by promoting release hook 4, simultaneously with 3 compressions of the spring on the tup 5, after reaching the pressure of regulation, the work of stop solution press pump discharges tup 5 by making release lever 2 open release hook 4, and tup 5 moves downward under the positioning action of guide pillar 9 and impacts chopping block 7 generation high frequency artificially seismic waves.
The present invention is through the seismic prospecting site test, hypocentrum cartridge spectrogram 2 and with compressional wave spectrogram of the present invention 3 contrasts, Fig. 3 has wideer motivated frequency bands and abundanter stimulating frequency than Fig. 2, conventional buckle spectrogram 4 is compared with shear wave spectrogram 5 of the present invention, compare its hypocentrum cartridge Fig. 5 and conventional buckle focus spectrogram 4, wideer with the physical shock hammer as the spectral range of the present invention of focus, more be applicable to the exploration of shallow-layer high-frequency seism.By shown in Figure 6, hammer the single-shot record into shape with physical shock and have identical energy effect with 3 folded records that hang down, and stable, good reproducibility.
