Description

Technical Field

[0001] The utility model relates to the technical field of pipe deformation monitoring, in particular to a composite material pipe inner diameter deformation monitoring device. Background Art

[0002] Ring stiffness refers to a pipe's ability to resist deformation when subjected to circumferential forces. It directly reflects its ability to withstand external pressure loads and is a key indicator for evaluating pipe performance. Insufficient ring stiffness can lead to excessive deformation or even rupture, impacting its service life and functionality. Therefore, monitoring ring stiffness is crucial to ensuring the structural safety and durability of pipelines.

[0003] Conventional technology monitors the ring stiffness of glass composite tubes by monitoring the deformation of the tube ring after stress is applied using the displacement of the testing machine's crossbar. This measurement method is suitable for testing tubes with large contact surfaces, such as plain tubes. However, for reinforced tubes, since stress is applied only to the ribs, which then transmit the force to the tube ring through the ribs, the "point" contact between the tube and the testing machine can easily lead to different degrees of deformation at different locations on the tube, affecting the accuracy of the ring stiffness monitoring results.

[0040] like Figures 1 to 2 As shown, this embodiment provides a pipe inner diameter deformation monitoring device, including a fixed base 1, a monitoring structure 2 and a control structure. The fixed base 1 is configured to be supported on the ground, and the monitoring structure 2 is adjustable in the vertical direction on the fixed base 1 to ensure that the monitoring structure 2 is within a suitable monitoring range. The monitoring structure 2 extends into the pipe 100 to be monitored and is arranged parallel to the monitoring point on the inner wall of the pipe 100 to monitor the change in the inner diameter of the pipe 100. The control structure is connected to the monitoring structure 2 and is used to receive the monitoring results of the monitoring structure 2. The setting of the monitoring structure 2 can monitor the deformation of the pipe 100 after being subjected to a certain pressure in real time, ensuring the accuracy and real-time nature of the monitoring. In addition, it can also ensure the accuracy of the monitoring results of the reinforced pipe 100, and has good applicability.

[0041] Optionally, the monitoring structure 2 includes a monitoring platform 21 and multiple monitoring sensors 22. The monitoring platform 21 extends horizontally and is vertically adjustable on the fixed base 1. The monitoring platform 21 extends into the pipe 100 to be monitored and is positioned parallel to the monitoring points on the inner wall of the pipe 100. Multiple monitoring sensors 22 are spaced apart on the monitoring platform 21 along the axis of the pipe 100; each monitoring sensor 22 is connected to the control structure and can monitor the changes in the inner diameter of the pipe 100 in real time, ensuring the accuracy of the monitoring results.

[0042] Specifically, in this embodiment, the monitoring platform 21 is rod-shaped; in other embodiments, the monitoring platform 21 may also be plate-shaped.

[0043] Exemplarily, the monitoring sensor 22 is a laser ranging sensor, which is an existing structure already disclosed in the prior art. Its specific structure and principle are referenced in the prior art and are not described in detail here. In addition, the control structure is a terminal device capable of receiving the monitoring results of the monitoring sensor 22, such as a computer, and its specific structure and form are referenced in the prior art.

[0044] Optionally, the pipe inner diameter deformation monitoring device further includes a lifting structure 3. The lifting structure 3 comprises a fixed rod 31 and an adjustment rod 32. The fixed rod 31 is fixed to the fixed base 1 and defines an adjustment cavity extending vertically. One end of the adjustment rod 32 is adjustable and extends into the adjustment cavity, while the other end is connected to the monitoring structure 2. Specifically, in this embodiment, the adjustment rod 32 is connected to the monitoring platform 21. By vertically adjusting the position of the adjustment rod 32 within the adjustment cavity, the height of the monitoring structure 2 can be adjusted vertically, placing the monitoring sensor 22 within a suitable monitoring range.

[0045] Furthermore, the lifting structure 3 includes an adjustment assembly 33. The adjustment assembly 33 comprises a worm and a worm wheel. The worm extends horizontally and is rotatably disposed outside the adjustment rod 32. The worm wheel is threaded onto the outside of the adjustment rod 32 and engages with the worm. Rotating the worm drives the worm wheel. The threads of the worm wheel and the adjustment rod 32 cooperate to move the adjustment rod 32 vertically upward and downward, thereby adjusting the position of the adjustment rod 32. This arrangement is simple and convenient to operate, and improves adjustment efficiency.

[0046] Specifically, in this embodiment, the adjustment component 33 also includes a protective shell, which is arranged on the outside of the worm wheel and part of the worm to prevent debris from entering the meshing point of the worm wheel and worm, thereby ensuring the smoothness of the height adjustment of the adjustment rod 32.

[0047] Furthermore, the adjustment assembly 33 further includes an operating dial 331. The operating dial 331 is fixed to one end of the worm, and the worm can be rotated by rotating the operating dial 331, making the operation more convenient and quick.

[0048] Optionally, an anti-slip portion is provided on the outer wall of the operating dial 331. Specifically, the anti-slip portion is a protective pad, such as a rubber pad, provided on the outer wall of the operating dial 331. Alternatively, the anti-slip portion is provided in the form of anti-slip protrusions on the outer wall of the operating dial 331. The anti-slip protrusions can be dot-shaped protrusions or patterned protrusions of any shape. Their function is to increase the contact friction between the operator's hand and the operating dial 331. The specific form of the anti-slip portion is referenced in the prior art and is not specifically limited in this embodiment, as long as it can increase friction.

[0049] Optionally, an operating rod 332 is protruded from the outer side of the operating dial 331. The operator holds the operating rod 332 and rotates the operating dial 331, which makes the operation more convenient and quick.

[0050] Optionally, a fixing plate 321 is provided at one end of the adjustment rod 32 near the monitoring structure 2, and the monitoring structure 2 is detachably mounted on the fixing plate 321. Specifically, in this embodiment, the monitoring platform 21 is detachably mounted on the fixing plate 321 using bolts commonly used in the art, which facilitates installation and removal and facilitates subsequent maintenance of the monitoring structure 2.

[0051] Optionally, a reinforcement member 11 is provided between the fixing rod 31 and the fixing base 1 to improve the connection strength between the fixing rod 31 and the fixing base 1 and ensure the overall stability of the equipment during the monitoring process.

[0052] Specifically, in this embodiment, the reinforcement member 11 is a reinforcement plate connected between the fixing rod 31 and the fixing base 1 .

[0053] Optionally, a plurality of moving wheels 12 are provided on the bottom side of the fixed base 1 to facilitate the movement of the device.

[0054] Optionally, a plurality of supporting legs 13 are provided on the bottom side of the fixed base 1 to further improve the stability of the fixed base 1 supported on the ground.

[0055] Specifically, in this embodiment, two moving wheels 12 and two supporting legs 13 are provided; in other embodiments, the number of moving wheels 12 and two supporting legs 13 can be set as needed and is not specifically limited here.

[0056] For example, the operating process of the pipe inner diameter deformation monitoring equipment described in this embodiment is as follows: The operator wears protective equipment and places the pipe 100 to be monitored in the center of the stiffness testing machine. The monitoring platform 21 is inserted into the pipe 100. The operating lever 332 is rotated to drive the worm to rotate, so that the adjustment lever 32 moves in the vertical direction, and the monitoring platform 21 is adjusted to an appropriate height to ensure that the monitoring sensor 22 is within the appropriate measurement range. At the same time, the position of the fixed base 1 is adjusted so that the monitoring platform 21 is parallel to the monitoring point on the inner wall of the pipe 100. The stiffness testing machine applies a certain amount of pressure to the pipe 100, and the control structure receives the deformation detected by each monitoring sensor 22.
