Description

Technical Field

[0001] The present invention belongs to the technical field of drainage pipeline detection in municipal engineering, and particularly relates to a detection device for detecting the deformation rate of a pipeline and a use method thereof. Background Art

[0002] In the construction of municipal engineering pipelines, when the flexible pipeline is backfilled to the designed elevation, the deformation rate of the pipeline should be measured and recorded within 12 - 24 hours. When the inner diameter of the pipeline is greater than 800 mm, the deformation rate of the pipeline can be directly detected by manual entry into the pipeline. For pipelines with an inner diameter that cannot be entered manually, the specification requires that optical, electrical measurement and other methods or the mandrel method can be used for detection. When detecting the deformation of small pipelines, although these instruments have high measurement accuracy and are relatively advanced, the cost of the equipment and its convenience of use cannot meet the actual requirements.

[0024] The present invention will be further described below in conjunction with the embodiments and the drawings:

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "set" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations

[0026] In one embodiment of the present invention, as Figure 1 a front view of a detection device for detecting the deformation rate of a pipeline and Figure 2 a top view of a detection device for detecting the deformation rate of a pipeline and also Figure 3 a side view of a detection device for detecting the deformation rate of a pipeline shown, a detection device for detecting the deformation rate of a pipeline includes: a fixing member; a detecting member disposed on the fixing member for detecting the deformation rate of the pipeline 11; a control member disposed on the fixing member for adjusting the height of the detecting member

[0027] Specifically, the fixing member includes a support rod 1 and a base 4. The support rod 1 is made of steel pipe and welded to the base 4, with a height higher than the diameter of the pipeline 11, and is used to fix the detection member and the control member; the base 4 is made of steel plate, with an X-shaped shape, and the support rod 11 is welded at the exact middle position of the X-shaped steel plate to fix the support rod 1.

[0028] The detection member includes a wire winding wheel 2, a fixator 6 and a chemical wire 7. The fixator 6 includes a fixing sleeve and a first bolt. The fixing sleeve is made of steel, sleeved tightly on the support rod 1, and there is also a through hole on the fixing sleeve, with a size and specification matching that of the first bolt. After finding the appropriate position, it is fastened with the first bolt; the wire winding wheel 2 is made of steel, with an ordinary rotating wheel shape, and is rotatably connected to the fixing sleeve, and is used to place the chemical wire 7. There is also a handle 8 on the wire winding wheel 2 to facilitate manual or mechanical rotation of the wire winding wheel 2 to keep the chemical wire 7 in a taut state at all times during detection; the chemical wire 7 is wound around the wire winding wheel 2. During use, one chemical wire 7 is connected to the wire winding wheels 2 of two detection devices to detect the deformation rate of the pipeline 11. The design of the detection member greatly reduces the detection cost, and at the same time, it is convenient for installation and disassembly, and can detect the deformation rate of pipelines with an inner diameter smaller than the length of the support rod 1.

[0029] The control member includes a wire position control rod 3 and a regulator 5. The wire position control rod 3 is made of steel, with a cylindrical thin tube shape, and is welded to the adjusting sleeve to adjust the height of the chemical wire 7. The weight should be appropriate. Being too light will cause the wire position control rod 3 to be unable to adjust the height of the chemical wire 7, and being too heavy will cause the chemical wire 7 to break; the regulator 5 includes an adjusting sleeve and a second bolt. The adjusting sleeve is sleeved tightly on the support rod 1, and there is also a through hole on the adjusting sleeve, with a size and specification matching that of the second bolt. The second bolt is placed on the adjusting sleeve to fix the position of the adjusting sleeve, and the adjusting sleeve then adjusts the position of the wire position control rod 3.

[0030] In use, first calculate the maximum deformation value allowed by the specification of the pipeline 11 before detection, and this maximum deformation value is used as the initial height reference value of the chemical line 7 during detection. First, install two detection devices in two adjacent inspection wells of the pipeline 11. The chemical line 7 penetrates into the interior of the pipeline 11 along the drainage direction of the pipeline 11, and both ends are tied and wound around two wire reels 2, and the chemical line 7 is straightened. According to the initially calculated initial height reference value, use the adjuster to control the position of the line position control rod 3. The line position control rod 3 adjusts the height of the initial chemical line 7, and the chemical line 7 always remains parallel to the pipeline 11. If it is not parallel to the pipeline 11, it will make the final test result inaccurate. Connect the sound emitting device 9 to one end of the chemical line 7, turn on the sound emitting device 9, and emit a sound signal. The sound signal is transmitted from one end of the chemical line 7 to the other end. If the sound signal can be sensed at the other end of the chemical line 7, then move the chemical line a small part in a direction closer to the inner wall of the pipeline 11. The moving distance depends on the accuracy of the required result. After adjusting the height of the chemical line 7, continue to let the sound emitting device 9 emit a sound signal until the sound signal cannot be sensed at the other end of the chemical line 7, then use a scale 10 to measure the distance between the current position of the chemical line 7 and the highest point of the inner wall of the pipeline 11 and record it, and the detection is completed. If the sound signal cannot be directly sensed at the other end of the chemical line 7, then move the chemical line 7 in a direction away from the inner wall of the pipeline 11. The moving distance depends on the accuracy of the required result. After adjusting the height of the chemical line 7, continue to let the sound emitting device 9 emit a sound signal until the sound signal can be sensed at the other end of the chemical line 7, then use a scale 10 to measure the distance between the current position of the chemical line 7 and the highest point of the inner wall of the pipeline 11, subtract the moving distance and record it, and the detection is completed.

[0031] In another embodiment of the present invention, the fixing member includes a support rod 1 and a base 4. The support rod 1 is made of a steel pipe, which is a telescopic steel pipe and is welded to the base 4, and its height is higher than the diameter of the pipeline 11, and is used to fix the detection member and the control member; the base 4 is made of a steel plate, and its shape is rectangular. The support rod 11 is welded at the exact middle position of the rectangular steel plate and is used to fix the support rod 1. The telescopic design of the support rod 1 can enable the detection device to detect the deformation rate of pipelines at different heights, greatly increasing the utilization rate of the detection device and reducing the detection cost.

[0032] The above has described multiple embodiments of the present invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
