The detecting column 6 can detect power pipes with different diameters, so that the application range of the device is wide, when the detecting column is implemented, taking fig. 5 as an example, the timing jacket 4 seals the air outlet 607 under normal conditions, then, once the detecting head 9 slides into a recess or a scratch, the pushing and lifting spring 304 will rise, then the position clamping column 601 will be pushed, so as to push the lifting column 603, the blocking sleeve 604 and the pulling sleeve 605 to rise together, while the rising pulling sleeve 605 will pull the pushing and turning block 408 to move together, then, the rising pushing and turning block 408 will push and open the jacket assembly at the air outlet 607, at this time, the gas in the air bag 303 will be discharged through the air outlet 607, so that the mechanism in the distance measuring cylinder 5 moves, and thus, the detecting and positioning operations are realized.
When the power tube with a larger or smaller diameter is measured, the detection head 9 is pushed by the push-up spring 304 (the push-up spring 304 can be selected as a spring) so that the air outlet 607 protrudes upward out of the timing envelope 4 or downward into the air bag 303, and then if the detection head 9 detects a dent or scratch on the inner wall of the tube, the deflation operation cannot be realized.
Therefore, at this time, the user can select to rotate the detecting head 9 to drive the lifting column 603 to rotate, the end of the lifting column 603 is located in the sliding slot 602, and the shaking or deviation cannot easily occur, and then the rotating lifting column 603 drives the blocking sleeve 604 and the pulling sleeve 605 to move up and down together (the working principle of the position can refer to the lead screw) until the air outlet 607 moves to the state shown in fig. 5 (i.e. the air outlet 607 is just sealed by the timing sleeve 4).
As shown in fig. 1 and 2, a fixing block 305 connected with the inner wall of the air bag 303 is arranged in the push-up spring 304, a pressure detector 7 is installed on one side surface of the fixing block 305 near the position clamping column 601, the pressure detector 7 comprises a lower pressing ball 8 connected with the surface of the fixed block 305, a rising ball 701 with the same structure as the lower pressing ball 8 is arranged on one side of the lower pressing ball 8 far away from the fixed block 305, a connecting column 702 is arranged between the lower pressing ball 8 and the rising ball 701, the side wall of the connecting column 702 is connected with a pressing strip 703, one end of the pressing bar 703, which is far away from the connecting column 702, is provided with a pressing column 704 connected with the clamping column 601, the pressing ball 8 comprises a ball cover 801, a moving strip 802 is connected to the inner wall of the ball cover 801 in a sliding manner, a pressing block 803 is installed at one end of the moving strip 802, the other end of the moving strip 802 is connected with a pressing strip 703, a pressure measuring instrument 804 connected to the pressing block 803 is attached to the inner wall of the ball cover 801.
This pressure detector 7 is used for detecting the change volume of pipeline inner wall, and it turns into measuring pressure with measuring length, compares in the electric power pipe of normal pipe diameter promptly, and when sunken or scratch appears in the inner wall, the pressure value can diminish, and sunken or scratch is big more then the pressure value is little, only need make pipeline inner wall everywhere the pressurized pressure value when the follow-up maintenance of user equal can.
When a normal pressure value of a pipeline is detected, once the clamping post 601 presses the pushing spring 304, the pressing post 704 is also pushed, so that the pressing bar 703 is pressed towards the direction of the fixed block 305 by the pressing post 704, then the pressed pressing bar 703 pushes the moving bar 802 to slide clockwise along the inner wall of the ball cover 801, and the sliding moving bar 802 presses the pressure measurer 804 through the pressing block 803 (the pressure measurer 804 can be connected with an external computer through bluetooth or the like to obtain implementation detection data) to obtain a normal pressure value.
Once the dent or scratch is measured, the pressing strip 703 is slightly reset, so that the value detected by the pressure measurer 804 is smaller than the normal pressure value, and the variation of the inner wall of the pipeline is obtained.
As shown in fig. 1, 2 and 3, the detection head 9 includes a bearing sleeve 901 connected to an end of the lifting column 603 away from the positioning column 601, a measurement block 902 is installed on a surface of one side of the bearing sleeve 901 away from the lifting column 603, an air cavity 903 is disposed at an end of the lifting column 603 close to the bearing sleeve 901, and a plurality of blowing holes 904 with a cross section in an inverted V-shaped structure are disposed on a surface of one side of the bearing sleeve 901 close to the measurement block 902.
The detection head 9 can blow away impurities (such as cotton wool, foam and the like) in the pits or scratches during detection so that the detection result is not affected, and in the specific implementation, after the gas in the air bag 303 is released, the gas can be injected into the hollow sleeve 901 through the gas guide cavity 903 (the gas guide cavity 903 is provided with a guide hole communicated with the hollow column 502), and then the gas can blow the impurities through the blowing hole 904.
As shown in fig. 2, 3, 4 and 6, the thickness of the measuring block 902 is set to be linearly decreased from the end close to the bearing sleeve 901 to the end far from the bearing sleeve 901, the setting is such that the measuring block 902 can fully enter the recess or scratch, the side wall of the measuring block 902 is provided with a locking groove 905, the inner wall of the locking groove 905 is connected with an inclined column 906, the surface of the bearing sleeve 901 is provided with an adjusting sliding groove 907, the adjusting sliding groove 907 is provided with a driving block 908 connected with the inclined column 906, the driving block 908 is used to limit the position of the inclined column 906 so that the inclined column 906 is not easily dislocated and deviated, and the adjusting sliding groove 907 is used to hide the position of the inclined column 906 so that the measuring block 902 cannot be blocked by the inclined column 906 when entering the recess or scratch.
After the measuring block 902 is clamped in the recess or the scratch, if the inserting sleeve 2 is continuously pushed, the measuring block 902 can automatically slide out of the recess or the scratch, so that the measuring operation can be continuously carried out, the situation that the measuring head is clamped or scratched cannot easily occur, in the specific implementation process, once the measuring block 902 enters a deeper recess, if the inserting sleeve 2 is continuously pushed, the inclined column 906 can be attached to the edge of the recess, then the inclined column 906 can be pressed down by the edge of the recess, so that the measuring block 902 is pressed out of the recess, and the measuring block 902 can directly slide out of the recess, so that the inner wall of a pipeline can be protected, and the effect of protecting the measuring block 902 can also be achieved.
As shown in fig. 1 and 5, the timing jacket 4 includes a clamping sleeve 401 hermetically connected to the airbag 303, a sealing ring piece 402 is installed on one side of the clamping sleeve 401 close to a clamping column 601, a sliding groove 403 is formed in an inner wall of the clamping sleeve 401, a carrier strip 404 is connected in the sliding groove 403, correction springs 405 connected to an inner wall of the sliding groove 403 are installed on both side surfaces of the carrier strip 404, a blocking block 406 for blocking an air outlet 607 is installed at one end of the carrier strip 404 far from the clamping sleeve 401, a pushing spring 407 connected to an inner wall of the clamping sleeve 401 is installed on one side surface of the blocking block 406 far from the sealing ring piece 402, and a pushing and turning block 408 connected to a pulling sleeve 605 is installed on one side of the blocking block 406 close to the sealing ring piece 402.
The timing cover 4 can ensure that the measuring block 902 does not always emit gas no matter how deep the measuring block is clamped into the recess or the scratch, so that the normal operation of the device can be unaffected, in the specific implementation, the blocking block 406 can seal the gas outlet 607 under normal conditions, when the pulling sleeve 605 pulls the push-turn block 408 to move together, the blocking block 406 is driven by the push-turn block 408, and the upper end of the blocking block is deflected in the direction away from the gas outlet 607 (namely, after the detecting head 9 is clamped into the recess or the scratch, the push-up spring 304 can push the pulling sleeve 605 to move together, if the recess or the scratch is deeper, the rising height of the pulling sleeve 605 and the push-turn block 408 is larger, namely, the angle of deflection of the blocking block 406 is larger, the emitted gas is more indirect, the depth is larger, and vice versa), the deflected blocking block 406 can press the push-up spring 407, and the carrying strip 404 is also pressed by the deflected blocking block 406, so that the deflection state occurs, and the gas in the air bag 303 will be discharged rapidly, the pressure of the air bag 303 will be reduced (after the pressure of the air bag 303 is reduced, the pressure in the conduit 101 and the distance measuring cylinder 5 will also be reduced), and after the pulling sleeve 605 does not pull the push-over block 408 any more, the push-over spring 407 will be reset immediately (the force application time of the pulling sleeve 605 is relatively fast, and the push-over spring 407 will be reset immediately once the force application is stopped), so as to push the blocking block 406 to seal the air outlet 607 rapidly, and the gas discharged from the air bag 303 will make the mechanism in the distance measuring cylinder 5 move in the process, thereby facilitating the user to observe and know the initial position of the dent or the scratch.
Then, once the detection head 9 slides out of the dent or the scratch, the detection head 9 is pressed into the air bag 303, at this time, the pressure in the air bag 303 is increased, so that the mechanism is moved again from the measuring cylinder 5, and thus, a user can know the end position of the scratch or the dent.
As shown in fig. 1, the distance measuring cylinder 5 includes a measuring column 501 hermetically connected to the conduit 101 and having a scale on a side wall thereof, a piston block 502 is connected in the measuring column 501, and a glue column 503 extending into the conduit 101 is mounted on a surface of the piston block 502.
When the pressure in the bladder 303 changes, the pressure in the conduit 101 increases or decreases, thereby pushing the glue column 503 and the piston block 502 along the measuring column 501 for easy observation by the user.
As shown in fig. 1 and 7, a through hole 201 is formed in a position corresponding to the lifting column 603 on the surface of the insertion sleeve 2, an installation groove 202 is formed in the outer side wall of the insertion sleeve 2, a pressing bag 203 communicated with the through hole 201 is installed in the installation groove 202, a bag pressing strip 204 is installed on the surface of one side, away from the installation groove 202, of the pressing bag 203, a sliding block 205 is arranged on the bag pressing strip 204 in a penetrating manner, a traction strip 206 connected with the inner wall of the installation groove 202 is installed at one end of the sliding block 205, a sliding wheel 207 is connected to the other end of the sliding block 205, and the thickness of the bag pressing strip 204 is set in a linear descending trend from one end close to the bag pressing strip 204 to one end away from the bag pressing strip 204.
When the inserting sleeve 2 moves in the power tube, the sliding wheel 207 is driven to move towards the through hole 201, at this time, the movable sliding wheel 207 slides on the bag pressing strip 204 to deflect the bag pressing strip 204 towards the pressing bag 203 and press the pressing bag 203, at this time, the movable sliding wheel 207 stretches the traction strip 206, the pressed pressing bag 203 presses the air in the bag pressing strip into the through hole 201 to blow the sundries at the detection head 9, and when the inserting sleeve 2 stops (because a user needs to constantly pay attention to the distance measuring cylinder 5, the inserting sleeve 2 cannot be pushed rapidly and continuously), the traction strip 206 pulls the sliding block 205 and the sliding wheel 207 to reset, so that the pressing bag 203 is filled with air again, and the sundries blowing operation is carried out again later.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
