Description

A kind of borehole seismic meter automatically disengage machinery device

Technical field

This utility model relates to a kind of plant equipment installed for seismometer, more specifically a kind of borehole seismic meter Automatically disengage machinery device.

Background technology

China is the country of earthquake more than, and in order to monitor big city seismicity, such as Beijing-Tianjin area, Shanghai is super greatly City, takes protection against and mitigation of earthquake disasters Forewarning Measures to bring huge disaster to alleviate earthquake to the mankind, sets up earthquake pre-warning platform net, in advance Early warning is to currently reduce one of casualties feasible method, in order to avoid the interference of urban environment sets up seismological observation platform Net, in the deep well in 10 meters to 30 meters, underground, sets up seismometer earthquake pre-warning measuring platform, but current mounting technique is by ground Shake meter installation one by one, in deep-well, in order to constitute sheet of earthquake pre-warning net, needs to put into substantial amounts of material resources manpower weight Carry out simple still the most requisite seismometer installment work again, significantly limit the efficiency that earthquake pre-warning net is set up And the development of earthquake pre-warning.According to the electronic mounting system automatically installed, depart from, it is not only due to put into and maintenance cost High, it is also possible to the hidden danger such as occur the electronic system that causes due to various different geographical environments malfunctioning.

Utility model content

In order to solve that above-mentioned existing seismometer installation procedure is loaded down with trivial details, electronic system is again it cannot be guaranteed that its stability etc. are asked Topic, this utility model provide a kind of borehole seismic meter automatically disengage machinery device, concrete scheme is as follows:

A kind of borehole seismic meter automatically disengage machinery device, including being arranged at the body of seismometer internal stent, described Body is the cylindrical-shaped structure that inside is shaped to cavity, is positioned at bottom and is provided with locking spring, described locking in described Body Lumen Spring upper end is fixed with screens steel ball, and described screens steel ball is arranged over gag lever post；The lower end of described gag lever post forms adjacent The disengaging concave groove arranged and locking concave groove, the upper end of described gag lever post forms the protrusions snap of horizontal direction, described On the sidewall of body, protrusions snap position, corresponding described gag lever post upper end offers through hole, corresponding on the sidewall of described seismometer support Protrusions snap position, described gag lever post upper end offers draw-in groove；Offering fixing hole in the middle part of described gag lever post, described gag lever post leads to Cross the rotary shaft in fixing hole to be arranged on the inwall of described body.

Further, described gag lever post is in tilted layout internal in this, it is ensured that the protrusions snap of gag lever post upper end molding and ground Draw-in groove on shake meter rack side wall cooperates.

Further, the lower end of described protrusions snap is shaped to and the arc structure of card slot fit, described protrusions snap Upper end is shaped to horizontal structure, and the length of described protrusions snap, not less than the radius of body bottom surface, makes work process convexity card lifting Lock can stretch out draw-in groove thus ensure the normal work of release unit.

Further, described locking spring is connected by spring housing is fixing with the bottom of described body interior cavity, described The position of the bottom correspondence spring housing of body is provided with spring switch-operated response control, adjusts for adjusting the stroke of locking spring The sensitivity of de-kayser.

Further, described disengaging concave groove and the sphere size in locking concave groove are more than the spherical ruler of screens steel ball Very little, prevent screens steel ball in the course of the work within departing from concave groove or locking concave groove the stuck and then release unit that causes without Method normally works.

The beneficial effects of the utility model are, a kind of borehole seismic meter that the utility model proposes automatically disengage machinery Device, after operator utilize location bar that seismometer is reserved orientation, operator have only on deep-well make location Bar is to bottom offset one segment distance, and then gag lever post rotates to an angle counterclockwise, and screens steel ball moves to take off from locking concave groove In concave groove, now protrusions snap leaves draw-in groove, and release unit separates with seismometer support, operator location bar with Automatically disengage machinery device to propose together on well head, location, this device work effect are installed to the most again next borehole seismic meter Rate height, Stability Analysis of Structures, simple to operate, do not affected by the working environment that work is severe, produce and maintenance cost the highest, it is simple to push away Extensively.
