Abstract
The utility model relates to a measuring instrument damping device, in particular to a damping device special for an underground measuring instrument. The technical scheme includes that the damping device comprises a transition joint, a damping rod, a colloid fixing cavity, a shell, a ring, a joint, a damping cavity and colloidal silica, the damping rod is movably connected with the transition joint, the ring in threaded connection with the shell is arranged on the outer surface of the damping rod, an outer end portion of the shell is movably connected with the joint, the damping cavity is formed between the shell and the damping rod, and the colloidal silica is arranged in the damping cavity. The damping device has the advantages that the damping device is simple in structure, reasonable in design and capable of increasing working time of the measuring instrument, and lowering of cost is realized; the damping device is more convenient in underground use and good in damping effect.
Description
Technical field
The utility model relates to a kind of measuring instrument damping device, particularly a kind of underground measuring instrument shock absorbing device special.
Background technology
At present, underground measuring instrument easily produces vibrations in the course of the work, the vibrations that produce due to the variety of issue of the initiations such as complicated geology, mud, tubing string like this shake instrument battery, sensor or pulser etc. in the course of the work, these vibrations easily affect the application life of underground measuring instrument, also affect accuracy of measurement, thereby the normal work of impact, increases cost of production.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of underground measuring instrument shock absorbing device special is provided.
Its technical scheme is: comprise transit joint, decoupling rod, colloid lock chamber, shell, circle, joint, damping cavity, colloidal silica, described decoupling rod is flexibly connected with transit joint, the external surface of decoupling rod is provided with the circle being connected with outer casing screw, the outer end of shell is flexibly connected with joint, between shell and decoupling rod, form damping cavity, in damping cavity, be provided with colloidal silica.
Above-mentioned decoupling rod is threaded with transit joint, and forms colloid lock chamber between transit joint and the end of decoupling rod.
The beneficial effects of the utility model are: of the present utility model simple in structure, reasonable in design, and can make the working time of measuring instrument extend, thereby realize, reduce costs; In addition, the utility model is used convenient in down-hole, good damping effect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: transit joint 1, decoupling rod 2, colloid lock chamber 3, shell 4, circle 5, joint 6, damping cavity 7, colloidal silica 8.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises transit joint 1, decoupling rod 2, colloid lock chamber 3, shell 4, circle 5, joint 6, damping cavity 7, colloidal silica 8, described decoupling rod 2 is threaded with transit joint 1, and form colloid lock chamber 3, the external surface of decoupling rod 2 is provided with the circle 5 being threaded with shell 4, the outer end of shell 4 is threaded with joint 6, between shell 4 and decoupling rod 2, form damping cavity 7, in damping cavity 7, be provided with colloidal silica 8.
Of the present utility model simple in structure, reasonable in design, can make the working time of measuring instrument extend, thereby realize, reduce costs; In addition, the utility model is used convenient in down-hole, good damping effect.
