Detailed description of the invention
For ease of those skilled in the art, technical scheme and beneficial effect are understood, in conjunction with accompanying drawing to tool
Body embodiment is described below.
Referring to shown in Fig. 1, it is the structural representation of dish tray (well) diameter detector of the present invention, including cable 12 of going into the well, and itself and set
The top of cylinder 2 connects, and this junction rubber protecting jacket 1 is socketed, can be directly by holding 12 dish footpaths inspections of cable of going into the well
Surveying instrument and put in stake holes, whole instruments weight is born by cable 12 of going into the well.Rubber protecting jacket 1 can reduce the impulsive force of outside,
Cable 12 of avoiding going into the well when dish tray (well) diameter detector proposes well head collides with well-head frame because swinging excessive with sleeve 2 junction, protects
Protect cable 12 of going into the well to be not damaged by.
The bottom of sleeve 2 barrel connects has four to measure lower limb 3, becomes umbrella after opening, and the bottom of each measurement lower limb 3 is pre-
Staying a groove, outer survey lower limb 9 to be made up of two parts between 90 °-180 ° at an angle to each other, its one end is at groove and measurement lower limb
3 are screwed connection, prevent during lower opening, because outer survey lower limb 9 encounters hole wall, the movement of certain angle occur, and impact is surveyed
The accuracy of amount.Referring to shown in Fig. 2 and Fig. 3, the wedge angle a that its mesopore both sides highlight is extruding-enlarging branch tray, in prior art, does not has
The diameter detecting instrument of outer survey lower limb 9, it cannot complete to measure under maximum measures angle α, and owing to practical situation is complex, Fig. 2 is only
Representing a kind of situation, but be mounted with the dish tray (well) diameter detector of outer survey lower limb 9, the outer survey lower limb 9 of expenditure forms certain angle with measuring lower limb 3
Degree, compensate for straight legs and cannot deform the defect measuring branch, make outer survey lower limb 9 can arrive each position of branch as far as possible
Put, fully measure.The bottom of each measurement lower limb 3 is fixing connects a wire drawing 10, and the other end of wire drawing 10 is wrapped in control electricity
On machine 11.At the slide potentiometer that is internally provided with of sealing drum, the contact of the corresponding slide potentiometer of each measurement lower limb 3, because of
This is realized the control function of position measuring lower limb 3 by slide potentiometer, and output aperture or the value in dish footpath.Sliding in order to ensure
Electrokinetic potential device is not damaged by external substance, so arrange an above-mentioned sleeve 2 again in the outside of sealing drum.
There is a pressure compensator 4 at center through the bottom of sleeve 2, and it is an Oil resistant rubber tube, through with sealing drum, energy
Enough ensureing sealing drum internal and external pressure balance, mud will not invade in sealing drum.Surrounding at pressure compensator 4 arranges four
Post 5, the upper end of pillar 5 is fixed on bottom sleeve 2, and lower end is fixed on Flos Mume dish 7, plays the effect of support, protects pressure simultaneously
Force compensating device.In the side of Flos Mume dish 7, it is fixedly connected with the restraining 6 with hole clipping, after completing to measure work, restraining 6
Measurement lower limb 3 is fettered, utilizes latch to fix.Utilize restraining 6 constraint to measure lower limb 3, make measurement lower limb 3 convenient when reclaiming, and
And restraining 6 is at measurement lower limb 3 medium position, makes it fetter when measuring lower limb 3 and being in rounding state, it is to avoid measure lower limb 3 and deform.
Connecting rod 8 one end is fixedly connected on the center bottom Flos Mume dish 7, and the other end is connected with controlling motor 11.Control
Motor 11 electrically connects with control device on the ground, when dish tray (well) diameter detector arrives the degree of depth needing to measure, by ground upper controller
Control the rotation of this control motor 11, release wire drawing 10, make measurement lower limb 3 strut with outer survey lower limb 9.
Its measurement process is: time on the ground, opened by restraining 6, due to the tensioning function of wire drawing 10, measures lower limb 3 still
It is in rounding state.Dish tray (well) diameter detector is progressively placed with in the hole of extruding-enlarging branch tray perfusion of mud, when arriving required measurement dish
During the degree of depth in footpath, the control device operatively gone up, make control motor 11 start to rotate, release wire drawing 10, measure lower limb 3 and outer survey lower limb
9 gradually become umbrella to open, until reaching to measure dish footpath.The signal of telecommunication is produced, under this signal warp by slide potentiometer
Well cable 12 is delivered to exterior display device, obtains the value in placing footpath.After measurement, dish tray (well) diameter detector is proposed aperture, passes through
Control device on the ground makes control motor 11 rotate, and strains wire drawing 10, measures lower limb 3 and draws in outer survey lower limb 9, and by restraining 6
Fettered, to avoid measuring the deformation of lower limb 3.
The foregoing is only presently preferred embodiments of the present invention, be merely illustrative for invention, and nonrestrictive.
Those skilled in the art understands, it can be carried out many changes, revise in the spirit and scope that invention claim is limited,
Even equivalence, but fall within protection scope of the present invention.
