Technical Field

[0001] The utility model relates to the technical field of settlement monitoring, in particular to an adaptive underground pipeline settlement monitoring device. Background Art

[0002] When monitoring the settlement of underground pipelines, it is impossible to directly monitor the settlement of underground pipelines due to limited space, and it is necessary to use underground pipeline settlement monitoring devices for monitoring. However, the existing monitoring devices are not tightly attached to the pipelines, resulting in unstable monitoring points and inaccurate monitoring results during the monitoring process. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an adaptive underground pipeline settlement monitoring device to solve the problem of inaccurate underground pipeline monitoring structure.

[0004] Based on the above purpose, the utility model provides an adaptive underground pipeline settlement monitoring device, including a guide tube and a monitoring rod, wherein the guide tube is located on the underground pipeline, and the end surface of the guide tube close to the underground pipeline is a curved surface corresponding to the curvature of the outer wall of the underground pipeline, and the curved surface is arranged in close contact with the underground pipeline;

[0005] The monitoring rod passes through the guide tube and abuts against the underground pipeline. A stabilizing mechanism is provided on the monitoring rod. The stabilizing mechanism is evenly arranged on the monitoring rod, and the axis of the stabilizing mechanism and the guide tube coincide.

[0006] Furthermore, the guide tube is provided with a bell mouth, the bell mouth is arranged close to the underground pipeline, and the curved surface is located on the bell mouth.

[0007] Furthermore, the bell mouth and the guide tube are detachably connected.

[0008] Furthermore, the bell mouth is a rubber bellows.

[0009] Furthermore, the stabilizing mechanism includes a support rod, which is arranged close to the underground pipeline, one end of the support rod is connected to the monitoring rod, and the other end of the support rod is abutted against the underground pipeline.

[0010] Furthermore, the monitoring rod is provided with a connecting piece, and the support rod is rotatably connected to the monitoring rod via the connecting piece.

[0011] Furthermore, the connecting piece is slidably connected to the monitoring rod, a protrusion is provided on the monitoring rod, the protrusion is arranged close to the underground pipeline, and the connecting piece is arranged away from the underground pipeline and abuts against the protrusion.

[0012] Furthermore, a fixing rod is provided between the support rod and the monitoring rod, one end of the fixing rod is rotatably connected to the support rod, and the other end of the fixing rod is rotatably connected to the monitoring rod.

[0013] Furthermore, the stabilizing mechanism is a circular ring structure, which is sleeved on the periphery of the monitoring rod and is adapted to the inner wall of the guide tube.

[0014] Furthermore, the monitoring device also includes a protective sleeve, which is sleeved on the outer periphery of the guide tube.

[0015] As can be seen from the above, the utility model provides an adaptive underground pipeline settlement monitoring device, which arranges an arc surface at one end of the guide tube, and the arc surface is adapted to the periphery of the underground pipeline, so that the guide tube can fit tightly with the underground pipeline through the arc surface, and the monitoring rod performs settlement monitoring through the guide tube, thereby avoiding the problem of inaccurate monitoring results due to the loose fit between the guide tube and the underground pipeline when performing underground pipeline settlement monitoring, thereby improving the monitoring accuracy of the monitoring device; in addition, a stabilizing mechanism is arranged on the monitoring rod, and the stabilizing mechanism coincides with the axis of the guide tube, and the monitoring rod is located at the center position of the stabilizing mechanism, so that the monitoring rod can pass through the center point of the arc surface of the guide tube and contact the corresponding underground pipeline when entering the guide tube for monitoring multiple times. Since the guide tube is fixedly connected to the underground pipeline, it can ensure that multiple measurements of the monitoring rod are in contact with the same point of the underground pipeline, that is, the same point is measured multiple times, further ensuring the accuracy of the measurement, thereby improving the accuracy of the monitoring device. The present application prevents the guide tube from being displaced by setting an arc surface on the guide tube that corresponds to the arc of the underground pipeline, and also sets a stabilizing mechanism that coincides with the axis of the guide tube to ensure that the monitoring rod is located on the axis of the guide tube. This allows the monitoring rod to contact the same position of the underground pipeline during multiple monitorings, avoiding the impact of contact at different positions on the monitoring accuracy, thereby improving the monitoring accuracy of the monitoring device.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be the usual meanings understood by people with ordinary skills in the field to which this application belongs.

[0024] In the prior art, when monitoring the settlement of underground pipelines, the monitoring device is not tightly fitted to the pipeline, and when the monitoring rod measures the same point multiple times, the monitoring point is inconsistent each time, resulting in low accuracy of the monitoring results.

[0025] The following is a detailed description of the technical solutions of one or more embodiments of the present application through specific embodiments. Figure 1 and Figure 2 As shown, an adaptive underground pipeline settlement monitoring device comprises a guide tube 11 and a monitoring rod 12, wherein the guide tube 11 is located on the underground pipeline 2, and the end surface of the guide tube 11 close to the underground pipeline 2 is a curved surface 1111 corresponding to the curvature of the outer wall of the underground pipeline 2, and the curved surface 1111 is arranged in close contact with the underground pipeline 2;

[0026] The monitoring rod 12 passes through the guide tube 11 and abuts against the underground pipeline 2 . A stabilizing mechanism 13 is provided on the monitoring rod 12 . The stabilizing mechanism 13 is evenly arranged on the monitoring rod 12 , and the axis of the stabilizing mechanism 13 coincides with the axis of the guide tube 11 .

[0027] The guide tube 11 is used for the monitoring rod 12 to pass through and contact the underground pipeline 2 to monitor the settlement of the underground pipeline 2. Therefore, the guide tube 11 is arranged on the underground pipeline 2 to facilitate the monitoring rod 12 to perform multiple settlement monitoring on the underground pipeline 2. In order to ensure that the same position of the underground pipeline 2 is monitored each time, the end face of the guide tube 11 in contact with the underground pipeline 2 is set to a curved surface 1111 consistent with the curvature of the outer wall of the underground pipeline 2, so that the guide tube 11 is closely arranged on the underground pipeline 2 to avoid displacement of the guide tube 11 due to loose fit with the underground pipeline 2, affecting the monitoring position and making the monitoring result inaccurate. The curved surface 1111 can be adaptively changed according to the diameter, i.e., curvature, of the underground pipeline 2, so that the guide tube 11 is closely fitted with the underground pipeline 2.

[0028] In addition, the stabilizing mechanism 13 is arranged on the monitoring rod 12. Firstly, the monitoring rod 12 can be stably arranged in the guide tube 11 under the action of the stabilizing mechanism 13, so that the monitoring rod 12 does not need to be manually stabilized when monitoring the underground pipeline 2, which is convenient for the monitoring rod 12 to perform monitoring work, and also avoids manual stabilization of the monitoring rod 12, which cannot ensure that the monitoring rod 12 is in an upright state every time, thereby affecting the monitoring accuracy; in addition, the stabilizing mechanism 13 is evenly arranged on the monitoring rod 12, and the stabilizing mechanism 13 coincides with the axis of the guide tube 11, so that the axis of the monitoring rod 12 passing through the guide tube 11 can be ensured to abut against the underground pipeline 2. Since the guide tube 11 is fixed on the underground pipeline 2, the monitoring rod 12 abuts against the same position of the underground pipeline 2 each time it monitors, thereby ensuring that the monitoring rod 12 monitors the same position of the underground pipeline 2 each time, further improving the monitoring accuracy.

[0029] In some embodiments, Figure 1 and Figure 2 As shown, the guide pipe 11 is provided with a bell mouth 111 , the bell mouth 111 is arranged close to the underground pipeline 2 , and the curved surface 1111 is located on the bell mouth 111 .

[0030] The diameter of the bell mouth 111 is larger than that of the guide pipe 11 . The guide pipe 11 is connected to the underground pipeline 2 via the bell mouth 111 , so that the guide pipe 11 can sit on the underground pipeline 2 , further improving the stability of the guide pipe 11 on the underground pipeline 2 .

[0031] In some embodiments, the bell mouth 111 is detachably connected to the guide tube 11. The arc surface 1111 is located on the bell mouth 111, and the arc surface 1111 corresponds to the curvature of the underground pipeline 2 (the curvature of the underground pipeline 2 is related to the diameter of the underground pipeline 2). The bell mouth 111 and the guide tube 11 are detachably connected, and the bell mouth 111 adapted to the curvature of the underground pipeline 2 can be installed on the guide tube 11 according to the curvature of the underground pipeline 2, that is, the underground pipeline 2 of different diameters, so that the guide tube 11 can fit the underground pipeline 2. Therefore, the detachable connection between the bell mouth 111 and the guide tube 11 can improve the applicability of the guide tube 11, and thus improve the applicability of the monitoring device 1.

[0032] In some embodiments, the bell mouth 111 is a rubber bellows.

[0033] The rubber bellows has softness and elasticity. Its softness can be used to squeeze the rubber bellows to fit it with the underground pipeline 2, and then the squeezing of the rubber bellows can be released to make it adsorb on the outer wall of the underground pipeline 2 using its own adsorption force, so as to achieve the purpose of stably connecting the guide tube 11 with the underground pipeline 2, thereby ensuring that the guide tube 11 is connected to the same part of the underground pipeline 2, providing the prerequisite for the subsequent fixation of the monitoring position, thereby improving the monitoring accuracy.

[0034] The bell mouth 111 can be extended and retracted by utilizing its elasticity. The extension and retraction of the bell mouth 111 can make the guide tube 11 extend along with the settlement of the underground pipeline 2, thereby preventing the guide tube 11 from being disconnected from the underground pipeline 2 due to the action of the settlement force during the settlement process of the underground pipeline 2, thereby affecting the monitoring accuracy. Therefore, its elasticity plays an important role in improving the monitoring accuracy of the monitoring device 1.

[0035] For example, in actual use, the end of the guide tube 11 close to the ground is fixed, and the rubber bellows on the guide tube 11 is adsorbed and fixedly connected to the underground pipeline 2. During the settlement of the underground pipeline 2, the underground pipeline 2 will drive the rubber bellows to move downward. The rubber bellows can extend along with the underground pipeline 2 by utilizing its elasticity, thereby avoiding the disconnection between the guide tube 11 and the underground pipeline 2, or the disconnection between the guide tube 11 and the ground, thereby enhancing the adaptability of the guide tube 11 and thereby enhancing the adaptability of the monitoring device 1.

[0036] In some embodiments, Figure 1 and Figure 3As shown, the stabilizing mechanism 13 includes a support rod 131 , which is disposed close to the underground pipeline 2 , one end of which is connected to the monitoring rod 12 , and the other end of which is in contact with the underground pipeline 2 .

[0037] The support rod 131 is used to support the monitoring rod 12 so that the monitoring rod 12 is in a vertical state in the guide tube 11 and coincides with the axis of the guide tube 11, thereby ensuring that the monitoring rod 12 monitors the same position of the underground pipeline 2 during multiple settlement monitorings, thereby improving the accuracy of the monitoring device 1.

[0038] Specifically, the length of the support rod 131 is related to the diameter of the underground pipeline 2, the inner diameter of the guide tube 11, and the height of the connection between the support rod 131 and the monitoring rod 12. According to the Pythagorean theorem, the support rod 131 is used to support the monitoring rod 12, and the height of the connection and the inner diameter of the guide tube 11 can determine its length. However, since the fulcrum of the support rod 131 is on the underground pipeline 2, the underground pipeline 2 is not a plane but an arc surface 1111. The length of the support rod 131 must also be compensated in part according to the curvature of the underground pipeline 2, thereby ensuring that the monitoring rod 12 can be stably set in the guide tube 11 under the action of the support rod 131.

[0039] In some embodiments, Figure 1 As shown, a connecting piece 133 is provided on the monitoring rod 12 , and the supporting rod 131 is rotatably connected to the monitoring rod 12 via the connecting piece 133 .

[0040] The support rod 131 is rotatably connected to the monitoring rod 12, and the angle between the support rod 131 and the monitoring rod 12 can be adjusted. After the monitoring rod 12 enters the guide tube 11, the support rod 131 is rotated so that there is a certain angle between the support rod 131 and the monitoring rod 12 to achieve the purpose of supporting the monitoring rod 12. When the monitoring rod 12 leaves the guide tube 11, the support rod 131 is rotated so that the support rod 131 and the monitoring rod 12 are arranged parallel to each other, so that the monitoring rod 12 can be folded up for easy storage.

[0041] Specifically, the support rod 131 is rotatably connected to the monitoring rod 12 via the connecting piece 133. By setting the connecting piece 133, the angle between the support rod 131 and the monitoring rod 12 is controlled to prevent the support rod 131 from rotating freely on the monitoring rod 12, thereby affecting the coincidence of the axis of the monitoring rod 12 and the guide tube 11, and further affecting the monitoring accuracy of the monitoring device 1.

[0042] In some embodiments, Figure 1As shown, the connecting member 133 is slidably connected to the monitoring rod 12 , a protrusion 134 is provided on the monitoring rod 12 , the protrusion 134 is arranged close to the underground pipeline 2 , and the connecting member 133 is arranged away from the underground pipeline 2 and abuts against the protrusion 134 .

[0043] In this embodiment, the protrusion 134 limits the sliding of the connecting member 133, so that the support rod 131 can maintain a fixed angle with the monitoring rod 12 under the action of the connecting member 133 and the inner wall of the guide tube 11 (i.e., the bell mouth 111) to fix the monitoring rod 12. When taking out the monitoring rod 12, the connecting member 133 can be moved to the upper end of the monitoring rod 12 by pulling the connecting member 133, so that the support rod 131 is arranged parallel to the monitoring rod 12, which facilitates the removal of the monitoring rod 12 and the stabilizing mechanism 13.

[0044] In some embodiments, Figure 3 As shown, a fixing rod 132 is provided between the support rod 131 and the monitoring rod 12, one end of the fixing rod 132 is rotatably connected to the support rod 131, and the other end is rotatably connected to the monitoring rod 12. The fixing rod 132 is used to limit the straight-line distance between the support rod 131 and the monitoring rod 12, so as to limit the angle between the support rod 131 and the monitoring rod 12, to avoid the angle between the support rod 131 and the monitoring rod 12 being too large, which affects the function of stabilizing the monitoring rod 12, and to avoid the support rod 131 from abutting against the inner wall of the guide tube 11 (that is, the bell mouth 111), which affects the stability of the guide tube 11, thereby improving the monitoring accuracy of the monitoring device 1.

[0045] In some embodiments, Figure 4 As shown, the stabilizing mechanism 13 is a circular ring structure, which is sleeved on the periphery of the monitoring rod 12 and is adapted to the inner wall of the guide tube 11 .

[0046] The stabilizing mechanism 13 is evenly arranged on the monitoring rod 12, that is, the monitoring rod 12 passes through the center point of the stabilizing mechanism 13, that is, the monitoring rod 12 coincides with the axis of the stabilizing mechanism 13. The periphery of the stabilizing mechanism 13 is adapted to the inner wall of the guide tube 11, so that the stabilizing mechanism 13 can move in the guide tube 11 without affecting the coincidence of the axis of the stabilizing mechanism 13 with the axis of the guide tube 11, so as to ensure that the monitoring rod 12 is located at the axis of the guide tube 11, and the monitoring position of the monitoring rod 12 in the underground pipeline 2 is also at the axis of the guide tube 11, so as to ensure that the monitoring position of the monitoring rod 12 is fixed, thereby improving the monitoring settlement accuracy of the monitoring device 1 and improving the monitoring precision.

[0047] Exemplarily, the stabilizing mechanism 13 is a circular ring structure made of rubber material, the monitoring rod 12 passes through the inner ring of the stabilizing mechanism 13 and is fixedly connected to the stabilizing mechanism 13, the outer ring diameter of the circular ring structure is the same as the inner diameter of the guide tube 11, and the stabilizing mechanism 13 enters the guide tube 11 under the guidance of the monitoring rod 12, the axis of the stabilizing mechanism 13 coincides with the axis of the guide tube 11, and the axis of the monitoring rod 12 also coincides with the axis of the guide tube 11, so that the stabilizing mechanism 13 is used to support and stabilize the monitoring rod 12, and the route of the monitoring rod 12 entering the guide tube 11 can be fixed, thereby fixing the position abutting against the underground pipeline 2, so that when the settlement of the underground pipeline 2 is monitored multiple times, the same position of the underground pipeline 2 is monitored, thereby improving the monitoring accuracy of the monitoring device 1.

[0048] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the monitoring device 1 further includes a protective sleeve 14, which is sleeved on the outer periphery of the guide tube 11. The protective sleeve 14 is used to protect the guide tube 11, and prevent the guide tube 11 from being corroded by other substances or organisms underground, which may affect the function of the guide tube 11 and further affect the monitoring accuracy of the monitoring device 1.
