Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0026] like Figures 1-5 As shown, the present invention provides a water pipeline deformation monitoring device comprising a monitoring vehicle 1, a level indicator 2, a centering adjuster 3, and a monitoring rod 4;

[0027] A level indicator 2 is installed on the monitoring vehicle 1 to observe and keep the monitoring vehicle 1 level.

[0028] The centering adjuster 3 is installed on the monitoring vehicle 1 and includes a first drive assembly 31 and a rotary connector 32; the first drive assembly 31 is used to drive the rotary connector 32 to move up and down, so that the rotary connector 32 is in the center of the water pipeline.

[0029] The monitoring rod 4 is horizontally connected to the rotating connector 32; the rotating connector 32 drives the monitoring rod 4 to rotate, and the monitoring rod 4 monitors the deformation of the water supply pipeline.

[0030] When monitoring a water pipeline, the monitoring vehicle 1 is first placed inside the pipeline. The position of the monitoring vehicle 1 is observed using the level indicator 2. The operator adjusts the monitoring vehicle to make it level, and then adjusts the rotating connector 32 through the first drive component 31 so that the rotating connector 32 is in the center of the water pipeline, thus completing the adjustment operation. The rotating connector 32 is then started, which drives the monitoring rod 4 to rotate. During the rotation of the monitoring rod 4, if the water pipeline deforms, it will cause the monitoring rod 4 to deform, thereby realizing the monitoring of the deformation of the water pipeline. The monitoring vehicle 1 moves continuously inside the water pipeline to complete the monitoring of various areas.

[0031] like Figure 2 As shown in the preferred embodiment, the monitoring rod 4 is provided with a first monitoring component 41, which includes a first connecting rod 411, a second connecting rod 412, a horizontal plate 413, a support rod 414, a return spring 415, a target ring 416, and a displacement sensor 417. One end of the first connecting rod 411 is hinged to the right end of the monitoring rod 4, and the other end is hinged to the right end of the horizontal plate 413. One end of the second connecting rod 412 is slidably connected to the left end of the monitoring rod 4, and the other end is hinged to the left end of the horizontal plate 413. The support rod 414 moves through the horizontal plate 413, and its lower end is connected to the target ring 416. The upper end of the support rod 414 is provided with a universal wheel 418 for fitting against the inner wall of the pipe. The return spring 415 is sleeved on the support rod 414. The displacement sensor 417 is set on the monitoring rod 4 and cooperates with the target ring 416 to measure the distance of the support rod 414 moving up and down, and monitor the deformation of the water supply pipe. During monitoring, the second connecting rod 412 is first slid to one end connected to the monitoring rod 4, so that the caster wheel 418 is pressed against the inner wall of the pipe. At this time, the second connecting rod 412 is fixed, the monitoring rod 4 rotates, and the caster wheel 418 rotates along the inner wall of the water supply pipe. When the water supply pipe deforms, the caster wheel 418 is squeezed and moves downward, which drives the support rod 414 to move down. The target ring 416 at the lower end of the support rod 414 moves down, and the displacement sensor 417 records the change in distance between the target ring 416 and the target ring 416, thereby determining whether the water supply pipe is deformed. In addition, the caster wheel 418 will move along the circumference of the pipe during the monitoring process, making the monitoring more comprehensive.

[0032] like Figure 2As shown, the monitoring rod 4 is also equipped with a second monitoring component 42, which is symmetrical to the first monitoring component 41. The structure of the second monitoring component 42 is the same as that of the first monitoring component 41. During monitoring, the second monitoring component 42 can be used simultaneously to collect data, facilitating data comparison and further improving accuracy.

[0033] like Figure 2 As shown, in a preferred embodiment, the monitoring rod 4 is provided with a transverse sliding groove 43, and one end of the second connecting rod 412 is slidably connected to the transverse sliding groove 43 via a first slider 419. Connecting one end of the second connecting rod 412 to the transverse sliding groove 43 of the monitoring rod 4 via the first slider 419 allows for more precise control of the sliding of the first slider 419, and also enables precise stopping of the sliding motion, by incorporating a motor and lead screw within the monitoring rod 4.

[0034] like Figure 3 As shown, in a preferred embodiment, the end of the support rod 414 is provided with a connecting seat 5, and a detection rod 51 is detachably provided on the connecting seat 5. A caster wheel 418 is provided at the upper end of the detection rod 51. The caster wheel 418 is connected to the detection rod 51. Since the detection rod 51 and the connecting seat 5 are detachably connected, it is convenient for later maintenance and replacement.

[0035] like Figure 3 As shown, in a preferred embodiment, the upper end of the connecting seat 5 is provided with a slot 52, and the side wall is provided with a wedge-shaped locking block 54 passing through the side wall of the slot 52 via a pull rod 53; the bottom of the detection rod 51 is provided with a wedge-shaped insert 55, and the side of the wedge-shaped insert 55 is provided with an insertion hole 56 that matches the wedge-shaped locking block 54. When connecting the detection rod 51, the wedge-shaped insert 55 at the bottom is inserted into the slot 2, and the pull rod 53 is pulled to insert the wedge-shaped locking block 54 into the insertion hole 56 to complete the fixation.

[0036] like Figure 3 As shown in the preferred embodiment, two wedge-shaped locking blocks 54 are provided, respectively disposed on opposite sidewalls of the slot 52, and two matching insertion holes 56 are also provided on the wedge-shaped insert 55. When fixing the wedge-shaped insert 55, two wedge-shaped locking blocks 54 are inserted into the insertion holes 56 for fixation, further improving stability.

[0037] like Figure 1As shown in a preferred embodiment, the centering adjuster 3 further includes a mounting base 33, on which a vertical scale 34 is provided. The first drive assembly 31 includes a first motor 311, a lead screw 312, and a second slider 313. The first motor 311 is mounted on the mounting base 33, and its output shaft is connected to the lead screw 312. The second slider 313 is screwed onto the lead screw 312, and a pointer 314 pointing horizontally to the vertical scale 34 is provided on the second slider 313. When using the centering adjuster 3, the first motor 311 is started to drive the lead screw 312 to rotate. Since the second slider 313 is screwed onto the lead screw 312, the second slider 313 slides up and down, causing the pointer 314 to point to the center of the vertical scale 34, thus completing the height adjustment.

[0038] like Figure 5 As shown in a preferred embodiment, the rotary connector 32 includes a second motor 321 and a rotating rod 322; one end of the rotating rod 322 is connected to the second slider 313, and the other end is connected to the monitoring rod 4; the second motor 321 is disposed inside the rotating rod 322, and its output shaft is connected to the monitoring rod 4 to drive the monitoring rod 4 to rotate. When using the rotary connector 32, the second motor 321 is started first, and the rotation of the second motor 321 will drive the monitoring rod 4 to rotate.

[0039] like Figure 1 As shown, in a preferred embodiment, the monitoring vehicle 1 is also equipped with a counterweight box 6. The counterweight box 6 is provided on the monitoring vehicle 1 to make the device more stable.

[0040] like Figure 4 As shown in the preferred embodiment, when it is necessary to perform deformation detection on the water pipeline, the monitoring vehicle is first placed into the pipeline through the inspection well of each pipe section. Since there is a counterweight at the bottom of the vertical rod, the vertical rod will drive the angle pointer to maintain a vertical state under its own weight. At this time, the attitude of the monitoring vehicle can be adjusted by the degree scale value on the left side of the horizontal indicator, until the angle pointer points to the 0° line, indicating that the monitoring vehicle has been adjusted to a horizontal state, in preparation for pipeline deformation detection.

[0041] The specific steps for using this device are as follows:

[0042] S1. When deformation detection of water pipeline is required, the monitoring vehicle is first placed into the pipeline through the inspection well of each pipe section. Since there is a counterweight at the bottom of the vertical rod, the vertical rod will drive the angle pointer to keep it in a vertical state under its own weight. At this time, the attitude of the monitoring vehicle can be adjusted by the degree scale value on the left side of the horizontal indicator, until the angle pointer points to the 0° line, indicating that the monitoring vehicle has been adjusted to a horizontal state, in preparation for pipeline deformation detection.

[0043] S2. After the monitoring vehicle is kept horizontal inside the pipeline, the motor on the starting screw is controlled to rotate according to the inner radius of the pipeline and the value indicated by the height pointer on the scale line on the front wall of the centering adjuster. This rotates the screw, which in turn moves the slider, causing the height pointer and the monitoring rod to move up and down. This makes the value indicated by the height pointer on the scale equal to the inner radius of the pipeline, so that the center point of the monitoring rod is located on the center line of the inner diameter of the pipeline, in preparation for subsequent monitoring.

[0044] S3. After the monitoring rod is positioned, start the No. 3 motor on the threaded rod to rotate the threaded rod, which pushes the moving block to the right. This causes the No. 1 and No. 2 rods to move closer together, so that the caster above the horizontal plate comes into contact with the inner wall of the pipe. At this time, adjust the distance between the displacement sensor and the target ring to the initial value and record it. Then, start the monitoring vehicle to move forward. When it encounters a deformed part of the pipe, the caster will be squeezed by the inner wall of the pipe or rebounded by the spring on the outer wall of the moving rod, which will cause the target ring at the bottom of the moving rod to move up and down. The displacement sensor will then detect the change in the distance of the target ring to determine whether the pipe is deformed. In addition, since the monitoring rod is connected to the rotator through the No. 2 bearing, starting the No. 2 motor in the rotator can rotate the monitoring rod, which will then cause the caster to rotate one revolution along the inner wall of the pipe to detect the circumferential deformation value of the pipe, making the monitoring more comprehensive.

[0045] S4. Additionally, when the length of the detection head is unsuitable and needs to be replaced, a suitable detection head can be taken, and the wedge-shaped insert at the bottom of the detection head can be inserted into the mounting base. At this time, the wedge-shaped insert will press the wedge-shaped locking block to move outward to make room until the wedge-shaped insert is fully inserted into the mounting base. The wedge-shaped locking block will encounter the slot and be inserted into the second rod under the rebound of the spring, thereby limiting and fixing the wedge-shaped insert and thus firmly connecting the detection head to the mounting base. In addition, since a pull rod is provided, pulling the pull rod will cause the wedge-shaped locking block to disengage from the slot, thereby releasing the limitation on the wedge-shaped insert and realizing the disassembly and replacement of the detection head.
