Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
1~Figure 11 of reference picture, the expanding inspection instrument for borehole camera centralising device of one kind rotation is by camera 1, push rod 2, electricity
Line 3, turnbarrel 4, big bearing 5, small bearing 6, support bar 7, roller 8, dial 9, saw-tooth ring 10 and rotational positioning component 11
Composition.
The camera 1 is sleeved in turnbarrel 4 and connected by two big bearing 5 so that turnbarrel 4 can be around
Camera 1 rotates；The push rod 2, electric wire 3 are connected with camera 1, are not contacted with turnbarrel 4；The support bar 7 is by small
Bearing 6 is fixed on the outside of camera 1, support bar 7 can around the small swing of bearing 6, what support bar 7 was not connected with camera 1
One end is equipped with the roller 8 vertically rolled, and when camera 1 is moved, roller 8 is in rolling contact with hole wall 12, reduces moving resistance；
The dial 9 is located at the top outer of camera 1, and the top of turnbarrel 4 is provided with fixed pointers 4-1, when turnbarrel 4 is rotated
When, pointer 4-1 points to different scale values, therefore can be required according to actual borehole size, it is determined that the specific anglec of rotation, is revolved by rotating
Rotaring sleeve 4 finally realizes required support scope；The saw-tooth ring 10 is fixed on the bottom of camera 1；The rotational positioning component
11 are located at turnbarrel bottom, including fixes sleeve 11-1, spring 11-2, fixture block 11-3 and plectrum 11-4, the fixed cover
Cylinder 11-1 is fixed on the inner side of turnbarrel 4, and spring 11-2 is installed in fixes sleeve 11-1, spring 11-2 other ends connection fixture block
11-3, the fixture block 11-3 is connected with plectrum 11-4, and fixes sleeve 11-1 sides are additionally provided with bar shaped guide groove 11-5 for plectrum 11-4
Slide.
As shown in figs. 7-9, the present invention is in use, the camera 1 is fixed, when turnbarrel 4 is rotated counterclockwise, and drives
Rotational positioning component 11 is rotated, and is influenceed by the tooth form of saw-tooth ring 10, fixture block 11-3 compression springs 11-2 so that spring 11-2 occurs
Elastic compression is deformed, fixture block 11-2 can counter-clockwise past the outside of saw-tooth ring 10 each sawtooth, until reaching the specified anglec of rotation,
Now rotate clockwise turnbarrel 4, fixture block 11-3 can not compression spring 11-2, that is, it is invalid to turn clockwise, if being needed after use
Carry out turnbarrel 4 to rotate clockwise, it is necessary to pull plectrum 11-4 so that fixture block 11-3 is moved, spring 11-2 forced compressions,
The sawtooth of saw-tooth ring 10 no longer limits fixture block 11-3, and now turnbarrel 4 can be rotated clockwise, and pointer 4-1 zeros, rotation is fixed
Hyte part 11 coordinates saw-tooth ring 10 to realize rotation and fixation of the turnbarrel 4 relative to camera 1.
As seen in figures 3-5, the present invention is in use, the support bar 7 passes through the first bar shaped of the top-side of turnbarrel 4
Emptying aperture 4-2, when the camera 1 relatively rotates with turnbarrel 4, support bar 7 is stretched laterally simultaneously along turnbarrel 4
Go out, expand support scope, be adapted to the drilling of different-diameter, it is ensured that the accurate centering of camera 1, it is to avoid underground water, landwaste
Pollution to camera, is effectively improved and spies on effect.
As shown in Figure 10, the plectrum 11-4, which is pulled, needs guiding through the second reserved bar shaped emptying aperture 4-3 of the bottom of turnbarrel 4,
The second bar shaped emptying aperture 4-3 and bar shaped guide groove 11-5 are completely corresponding.
When spying on operation in the borehole, camera 1 does not relatively rotate with turnbarrel 4, it is ensured that the present invention is in reality
The stability that border is spied in operation process.
The application method of the above-mentioned expanding inspection instrument for borehole camera centralising device of rotation, step is as follows：
Step 1, the anglec of rotation is determined：According to actual borehole size, it is determined that required support radius, support radius and the anglec of rotation
As shown in figure 11, O is the center of camera 1 and turnbarrel 4 to degree relation calculation diagram, and O ' is the center of small bearing 6, and A is finger
Pin 4-1 indicates initial position, and A ' is the backpointer 4-1 indicating positions that rotates to an angle, and B is the outer end roller 8 of support bar 7 and hole wall
12 contact positions, B ' is the outer end roller 8 of back support rod 7 and the contact position of hole wall 12 of rotating to an angle；Therefore it is OO ' distances, initial
Support radius OB, support bar 7 and roller 8 total length O ' B or O ' B ', the internal diameter OA or OA ' of turnbarrel 4, required support radius
OB ', ∠ O ' OB, ∠ OBO ', ∠ OO ' B, ∠ O ' OB are known；
In Figure 11 under rectangular coordinate system, circle O ' equation is：
Point B ' (xB′, yB′) on circle O ' and to the center of circle O (x of camera 1O, yO) distance be needed for support radius OB ',
Therefore：
It can then try to achieve known to ∠ BO ' B ', the i.e. anglec of rotation of support bar 7；
Respectively in Δ OO ' A ' and Δ OAB, it can be obtained using sine：
∠ O ' A ' O and ∠ OBA can be then tried to achieve, i.e.,：
∠ O ' OA '=180 °-∠ O ' A ' O- (∠ OO ' B+ ∠ BO ' B ') (8)
∠ AOB=180 °-∠ OAB- ∠ OBO ' (9)
So as to the anglec of rotation of turnbarrel 4 is：
∠ A ' OA=∠ O ' OB- ∠ O ' OA '-∠ AOB (10)
Step 2, turnbarrel is rotated：The camera 1 is fixed, turnbarrel 4 is rotated counterclockwise, reaches in step 1
Untill the anglec of rotation of determination, if the rotational angle of turnbarrel 4 needs revolution (to turn clockwise more than angle on target in rotation process
It is dynamic) when, outwards stir plectrum 11-4 so that fixture block 11-3 is moved, fixture block 11-3 departs from the limitation of saw-tooth ring 10, you can realize rotation
Rotaring sleeve 4 is rotated clockwise, and pointer 4-1, which is pointed to, discharges plectrum 11-4 after angle on target, turnbarrel 4 is relative with camera 1
Position is fixed immediately.
Step 3, operation is spied on：Camera 1 and the expanding inspection instrument for borehole camera centering of rotation are filled by push rod 2
Put push-in drilling to be detected, and record related data.
Step 4, reset and spy on operation next time：After observation is finished, take out camera 1 and the expanding drilling of the rotation is peeped
Depending on instrument camera centralising device, the camera 1 is fixed, plectrum 11-4 is outwards stirred so that fixture block 11-3 is moved, fixture block
11-3 departs from the limitation of saw-tooth ring 10, rotates counterclockwise turnbarrel 4, and pointer 4-1, which is pointed to, discharges plectrum 11-4 after initial angle,
Complete once to drill to spy on work, if proceeding drilling spies on operation, repeat step 2, you can carry out drilling next time and peep
Depending on work.
It is described above, only it is a kind of preferred embodiment of the present invention, not the present invention is imposed any restrictions, it is every according to this
Any simple modification, change and equivalent structure change that inventive technique is substantially made to above example, still fall within this hair
In the protection domain of bright technical scheme.
