Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline height detection, and more specifically, relates to the technical field of a municipal pipeline with height detection function. Background Art

[0002] Municipal pipelines are an important part of urban infrastructure. With the continuous intensification of urbanization, the density of municipal pipelines has gradually increased. Municipal pipelines can be roughly divided into three categories. The first category is municipal water pipes, which mainly include urban drainage pipes, sewage pipes, domestic water pipes and grey water pipes, etc.; the second category is communication or power pipes; the third category is gas pipes, mainly gas pipes.

[0003] Most municipal pipelines are buried underground, which effectively saves ground space. However, municipal pipeline settlement will occur due to the following aspects: Underground settlement: The settlement of underground soil layers will cause the pipeline to bear greater pressure, which may cause the pipeline to bend, twist, or even break. Construction defects: Problems during the construction process, such as incomplete road backfill and insufficient compaction, may also cause the soil around the pipeline to loosen, causing settlement. Influence of the external natural environment: Earthquakes, vehicle vibrations, blasting, and overloading can lead to unstable foundations and cause uneven settlement. Cross-construction: Different municipal facility units may excavate in the same area when laying or repairing pipelines, which will affect the compaction of the road and cause road settlement.

[0004] The potential impacts of municipal pipeline settlement are primarily manifested in the following areas: Interruptions in water, drainage, and gas systems: Pipeline ruptures can cause supply problems in these systems, impacting residents' lives. Safety incidents: Pipeline displacement and disconnection can lead to safety incidents such as leaks and explosions. Traffic problems: Road settlement can affect normal road use, causing congestion or even accidents. Therefore, regular monitoring of municipal pipeline settlement and height is necessary to prevent these potential risks.

[0005] Existing technologies such as CN215261730U, a structure for detecting the settlement of municipal pipelines, can achieve the detection of pipelines, but this type of detection cannot be presented intuitively to the inspectors, and because it is carried out through mechanical means such as racks, it may rust when buried underground. Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a municipal pipeline with height detection, so as to solve the technical problems in the prior art of municipal pipeline height detection errors caused by corrosion and the inability to intuitively display the detection results.

[0007] To achieve the above objectives, the technical solution adopted in this application is: a municipal pipeline with high detection, comprising:

[0008] An annular track, wherein the annular track is sleeved on the outer wall of the pipeline to be tested;

[0009] An annular swivel, comprising an annular sleeve, a counterweight, and a height measuring portion; the annular sleeve is sleeved outside the annular track and is rotatably connected to the annular sleeve; the counterweight and the height measuring portion are respectively provided on the side surfaces of the annular sleeve; the direction from the counterweight to the axis of the pipeline is orthogonal to the direction from the height measuring portion to the axis of the pipeline;

[0010] A reference component is buried at one side of the pipeline, and an upper end of the reference component penetrates the ground;

[0011] A measuring end of a U-shaped tube is provided in the height measuring portion, and a display end of the U-shaped tube is provided in the reference component; a liquid level detector is provided in the display end of the U-shaped tube, and the liquid level detector is electrically connected to the settlement difference display on the reference component.

[0012] Optionally, the height measuring part includes a measuring cavity, a drain pipe, the U-shaped tube and a first ventilation tube; the water inlet end of the drain pipe, the measuring end of the U-shaped tube and the air outlet end of the first ventilation tube are provided in the measuring cavity; the water outlet end of the drain pipe is connected to the drainage channel, and the air outlet end of the first ventilation tube is connected to the outside atmosphere.

[0013] Optionally, a cavity is provided at the lower end of the reference component, and the display end of the U-shaped tube is provided in the cavity; and a second ventilation pipe is provided in the cavity, and the second ventilation pipe is connected to the outside atmosphere.

[0014] Optionally, the liquid level detector includes a first float, a rotating rod, an arc-shaped rheostat and a first circuit board assembly; one end of the first float is connected to one end of the rotating rod through a connecting rod, and the other end of the rotating rod is connected to the first slider of the arc-shaped rheostat through a connecting rod; the first circuit board assembly and the arc-shaped rheostat form the same circuit.

[0015] Optionally, the liquid level detector includes a float, a cylindrical rheostat and a circuit board assembly; the float is connected to a slider of the cylindrical rheostat, and the circuit board assembly and the cylindrical rheostat form a same circuit.

[0016] Optionally, the circuit board assembly is connected to the settlement difference display via a wire, and the wire is laid axially along the reference component.

[0018] Optionally, the outer side of the pipeline is connected to the protective shell through a pipeline support frame, and the annular swivel is arranged in the protective shell.

[0019] The beneficial effect of the municipal pipeline height detection system provided by this application is that, compared with the prior art, the present invention provides a municipal pipeline height detection system that solves the aforementioned problems. The present invention utilizes a circular swivel mechanism to achieve rotation on a circular track. Because the counterweight is heavier than the height measurement unit, gravity causes the counterweight to rotate below the circular track, aligning the height measurement unit with the pipeline axis, facilitating adjustments by the installer.

[0020] In addition, the present invention also achieves indirect measurement of pipeline height changes through the provision of a U-shaped tube. The liquid levels at the display end and the measuring end of the U-shaped tube remain consistent, and the liquid level detector records the liquid level difference change at the display end, that is, the liquid level change at the measuring end.

[0021] In addition, the liquid level detector provided in the present invention can convert the detected liquid level difference changes into actual data and display them on the sedimentation difference display 30, which is more intuitive and convenient for measurement personnel to record.

[0047] In another embodiment of this application, please refer to Figures 3 to 7 The circuit board assembly 4211c or 421d is connected to the settlement difference indicator 30 via a wire, which is laid axially along the reference component 3. The circuit board assembly 4211c or 421d can record the current passing through the arc-shaped rheostat 421c or the cylindrical rheostat 4211b, thereby inferring the change in the resistance value of the arc-shaped rheostat 421c or the cylindrical rheostat 4211b based on the change in current. The resistance value of the arc-shaped rheostat 421c is linearly related to the first slider 51.
