Description

Technical Field

[0001] This utility model relates to the field of pipeline settlement monitoring technology, and in particular to a high-pressure gas pipeline settlement monitoring device that is quick to install and disassemble. Background Technology

[0002] Urban high-pressure gas pipelines are a vital component of a city's lifeline, and their safe operation is of paramount importance. However, with the rapid pace of urban development, especially large-scale construction projects such as subway tunneling and building foundation pit construction, the disturbance to the soil is significant. Uneven soil settlement can easily lead to shearing or bending damage and deformation of high-pressure gas pipelines, posing a huge challenge to their safe operation. To ensure the safe operation of urban high- and secondary high-pressure gas pipelines and the smooth progress of construction, settlement and deformation monitoring of urban steel gas pipelines near the construction area must be conducted during the construction period. This monitoring effectively guides construction, controls the construction speed, ensures the normal operation of construction and pipelines, and prevents safety accidents.

[0003] Existing settlement deformation monitoring methods for high-pressure gas pipelines mostly use clamps to connect and fix the pipeline. For example, Chinese patents with publication numbers CN110926413A, CN213120517U, CN216593346U, and CN207850355U all use the aforementioned clamp method for connection and fixation. However, this installation method has some drawbacks. For example, this connection method requires the entire pipeline to be excavated, and the anti-corrosion layer on the outside of the gas pipeline is easily damaged during the excavation process. In addition, the excavation area is large, and bolts are required for fixing, resulting in low work efficiency and high risk to the pipeline.

[0004] To address these issues, we propose a quick-assembly and disassembly high-pressure gas pipeline settlement monitoring device. Utility Model Content

[0005] This invention provides a high-pressure gas pipeline settlement monitoring device that is quick to install and disassemble, thereby solving the problems mentioned in the background art, such as the low installation efficiency and high risk of settlement monitoring devices that are connected to pipelines by clamps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-pressure gas pipeline settlement monitoring device that is quick to assemble and disassemble includes a first soft magnet and a second soft magnet arranged opposite to each other, a rotating cavity is provided between the first soft magnet and the second soft magnet, and a rotatable permanent magnet is provided in the rotating cavity, having a first position and a second position. When the permanent magnet rotates to the first position, the permanent magnet, the first soft magnet, and the second soft magnet form a magnetic circuit, and the first soft magnet and the second soft magnet are magnetized. When the permanent magnet rotates to the second position, the permanent magnet forms a magnetic short circuit with the first soft magnet and / or the second soft magnet, and the first soft magnet and the second soft magnet are demagnetized; The first soft magnet is a flexible soft magnet and has a deformable adsorption surface that contacts the pipeline. The adsorption surface is configured such that when it contacts the pipeline, it deforms to conform to the outer surface contour of the pipeline.

[0007] Furthermore, a magnetic shielding element is provided between the first soft magnet and the second soft magnet. The magnetic shielding element is located outside the rotating cavity and is arranged parallel to the rotation axis of the permanent magnet.

[0008] Furthermore, the permanent magnet has N poles and S poles, and a magnetic pole connection is formed between the N poles and the S poles.

[0009] Furthermore, when the permanent magnet is in the first position, the magnetic pole connection line is perpendicular to the magnetic shielding component, and the N pole and S pole are in contact with the first soft magnet and the second soft magnet, respectively, forming a magnetic circuit with the permanent magnet, the first soft magnet, and the second soft magnet.

[0010] Furthermore, when the permanent magnet is in the second position, the magnetic pole connection line is arranged parallel to the magnetic shielding component, and the N pole and S pole are connected through the first soft magnet and / or the second soft magnet, forming a magnetic short circuit between the permanent magnet and the first soft magnet and / or the second soft magnet.

[0011] Furthermore, it also includes a shell that surrounds the first soft magnet and the second soft magnet, with one end of the first soft magnet having an adsorption surface extending out of the shell, and a monitoring rod installed on the shell.

[0012] Furthermore, the adsorption surface is an arc surface, and multiple deformation grooves are formed on the surface of the adsorption surface. Multiple deformation cavities are formed inside the first soft magnet.

[0013] Furthermore, the permanent magnet is equipped with a rotating shaft, one end of which extends through the outer shell and has a insertion slot.

[0014] Furthermore, the outer casing is provided with a detachable rotating handle, and the rotating handle is provided with a plug-in post, which can be detachably plugged into the plug-in slot.

[0015] Furthermore, the rotary handle is also equipped with a swivel, and the surface of the outer shell is provided with two positioning plates; when the permanent magnet rotates to the first position, the swivel abuts against one of the positioning plates, and when the permanent magnet rotates to the second position, the swivel abuts against the other positioning plate.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention utilizes a combination of a first soft magnet, a second soft magnet, and a permanent magnet. When the permanent magnet, the first soft magnet, and the second soft magnet form a magnetic circuit, the two soft magnets are magnetized. The magnetized first soft magnet can then adhere to a steel pipeline, quickly securing the monitoring device to the pipeline. Conversely, when the permanent magnet forms a magnetic short circuit with the first and / or second soft magnets, the first and second soft magnets are demagnetized, allowing the monitoring device to be quickly removed from the pipeline. This magnetic connection method not only facilitates easy assembly and disassembly, significantly improving installation efficiency, but also employs non-invasive installation, requiring only partial exposure of the pipeline for operation, thus significantly reducing construction risks and operating costs.

[0017] By using a flexible material for the first soft magnet, the adsorption surface becomes deformable. When the radius of curvature of the adsorbed pipeline surface is greater than the radius of the adsorption surface, the adsorption surface can expand adaptively; when the radius of curvature of the pipeline surface is smaller than the radius of the adsorption surface, the two sides of the adsorption surface can contract inward. This structure allows the adsorption surface to automatically adjust its shape according to different pipe diameters, always maintaining a tight fit with the pipeline surface, significantly improving the adsorption stability and adaptability of the monitoring device.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] Please see Figures 1 to 8 : This utility model provides a quick-assembly and disassembly high-pressure gas pipeline settlement monitoring device, including a first soft magnet 100 and a second soft magnet 200 arranged opposite to each other, a rotating cavity 300 provided between the first soft magnet 100 and the second soft magnet 200, and a rotatable permanent magnet 400 provided in the rotating cavity 300, having a first position and a second position; wherein, when the permanent magnet 400 rotates to the first position, the permanent magnet 400, the first soft magnet 100 and the second soft magnet 200 form a magnetic circuit, and when the permanent magnet 400 rotates to the second position, the permanent magnet 400, the first soft magnet 100 and / or the second soft magnet 200 form a magnetic short circuit; like Figures 3 to 6 As shown, in a preferred embodiment, a magnetic isolation member 500 is provided between the first soft magnet 100 and the second soft magnet 200. The magnetic isolation member 500 is located outside the rotating cavity 300 and is arranged parallel to the rotation axis 404 of the permanent magnet 400. The permanent magnet 400 is provided with an N pole 401 and an S pole 402, and a magnetic pole connecting line 403 is formed between the N pole 401 and the S pole 402.

[0031] In this embodiment, when the permanent magnet 400 is in the first position, the magnetic pole connecting line 403 and the magnetic shielding member 500 are arranged perpendicularly to each other, and the permanent magnet 400, the first soft magnet 100, and the second soft magnet 200 form a magnetic circuit, and the first soft magnet 100 and the second soft magnet 200 are magnetized. When the permanent magnet 400 is in the second position, the magnetic pole connecting line 403 and the magnetic shielding member 500 are arranged parallel to each other, and the permanent magnet 400 and the first soft magnet 100 and / or the second soft magnet 200 form a magnetic short circuit, and the first soft magnet 100 and the second soft magnet 200 are demagnetized. The magnetic shielding member 500 is made of a non-magnetic material, such as aluminum or copper, which can isolate the magnetic lines of force between the first soft magnet 100 and the second soft magnet 200.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, when the permanent magnet 400 is in the first position, its N pole 401 and S pole 402 are in contact with the first soft magnet 100 and the second soft magnet 200, respectively. At this time, magnetic field lines can pass through the N pole 401 and enter the first soft magnet 100. The magnetic field lines of the first soft magnet 100 then enter the second soft magnet 200, and finally enter the S pole 402, thus forming a complete magnetic circuit. In this way, the magnetic field lines of the permanent magnet 400 can be dissipated to the outside, and the first soft magnet 100 and the second soft magnet 200 are magnetized and possess magnetic properties, allowing them to attract ferromagnetic materials.

[0033] like Figure 5As shown, when the permanent magnet 400 is in the second position, its N pole 401 and S pole 402 simultaneously contact the first soft magnet 100 and / or the second soft magnet 200, while the magnetic shielding component 500 separates the first soft magnet 100 and the second soft magnet 200. At this time, the magnetic field lines of the N pole 401 flow directly back to the S pole 402 through the first soft magnet 100 and / or the second soft magnet 200, thus forming a magnetic short circuit. Since no magnetic field lines are emitted to the outside, the first soft magnet 100 and the second soft magnet 200 will not possess magnetism and cannot attract ferromagnetic materials.

[0034] In other embodiments (not shown in the figures), the first soft magnet 100, the second soft magnet 200, and the permanent magnet 400 can be arranged in parallel, with gaps between them. When the permanent magnet 400 rotates to the first position, it is perpendicular to the first soft magnet 100 and the second soft magnet 200, with the N pole 401 and S pole 402 in contact with the first soft magnet 100 and the second soft magnet 200, respectively, and the first soft magnet 100 and the second soft magnet 200 are magnetized. When the permanent magnet 400 rotates to the second position, it is parallel to the first soft magnet 100 and the second soft magnet 200, and gaps between them. At this time, very few magnetic lines of force are emitted to the first soft magnet 100 and the second soft magnet 200, and the first soft magnet 100 and the second soft magnet 200 are either non-magnetic or in a state of slight magnetism.

[0035] Therefore, by switching the permanent magnet 400 between the first position and the second position, the first soft magnet 100 can be selectively magnetized or demagnetized, making the operation convenient and quick.

[0036] like Figures 1 to 5 As shown, this utility model also includes a housing 600 that surrounds the first soft magnet 100 and the second soft magnet 200. The first soft magnet 100 is a flexible soft magnet and has a deformable adsorption surface 101 that contacts the pipeline. The adsorption surface 101 is configured such that when it contacts the pipeline, it deforms to conform to the outer surface contour of the pipeline. One end of the first soft magnet 100 with the adsorption surface 101 extends out of the housing 600, and a monitoring rod 700 is mounted on the housing 600.

[0037] In a preferred embodiment, the adsorption surface 101 is an arc surface, and multiple deformation grooves 102 are formed on the surface of the adsorption surface 101. Multiple deformation cavities 103 are formed inside the first soft magnet 100. The permanent magnet 400 is provided with a rotating shaft 404, one end of which extends through the outer shell 600 and has a plug-in groove 4041. The outer shell 600 is provided with a detachable rotating handle 800, which is provided with a plug-in post 801, and the plug-in post 801 is detachably plugged into the plug-in groove 4041. The rotating handle 800 is also provided with a handle, and two positioning plates 601 are provided on the surface of the outer shell 600; when the permanent magnet 400 rotates to the first position, the handle abuts against one of the positioning plates 601, and when the permanent magnet 400 rotates to the second position, the handle abuts against the other positioning plate 601.

[0038] In this embodiment, the outer shell 600 is made of a non-magnetic material, or the portion where the first soft magnet 100 and the second soft magnet 200 connect is made of a non-magnetic material, thus preventing direct connection between the first soft magnet 100 and the second soft magnet 200. Simultaneously, an opening is provided at the top of the outer shell 600, such as... Figure 2 As shown, by setting an opening, when a magnetic circuit is formed between the permanent magnet 400, the first soft magnet 100, and the second soft magnet 200, it is ensured that the external magnetic lines of force can return to the second soft magnet 200.

[0039] The first soft magnet 100 is made of a flexible soft magnetic polymer composite material, such as magnetic rubber / silicone, magnetic plastic / injection-molded magnet, etc. This material allows the first soft magnet 100 to have the ability to elastically deform. The deformation cavity 103 and deformation groove 102 provide a deformation space for the deformation of the adsorption surface 101, allowing the two ends of the adsorption surface 101 to expand outwards or contract inwards.

[0040] Therefore, when the permanent magnet 400 is in the first position, the first soft magnet 100 can be attracted to the outer surface of the pipeline through the adsorption surface 101, thus allowing for a simple and quick connection between the detection device and the pipeline. By making the first soft magnet 100 a flexible material, the adsorption surface 101 becomes deformable. When the radius of curvature of the pipeline surface being adsorbed is greater than the radius of the adsorption surface 101, the adsorption surface 101 can expand adaptively; when the radius of curvature of the pipeline surface is smaller than the radius of the adsorption surface 101, the two sides of the adsorption surface 101 can contract and deform inward. This structure allows the adsorption surface 101 to automatically adjust its shape according to different pipe diameters, always maintaining a tight fit with the pipeline surface, significantly improving the adsorption stability and adaptability of the monitoring device. Furthermore, the magnetic connection method requires a small installation area, and operation can be performed with only partial exposure of the pipeline.

[0041] In this embodiment, the monitoring rod 700 extends upwards out of the ground and connects to the monitoring device (not shown in the figure). When the pipeline settles, the monitoring rod 700 moves downwards synchronously, and the monitoring device monitors the pipeline settlement by monitoring the displacement of the monitoring rod 700. The specific implementation method for the monitoring device to detect the displacement of the monitoring rod 700 is well-known in the art and will not be described in detail here. In other embodiments (not shown in the figure), graduations can also be directly engraved on the monitoring rod 700, so that when the monitoring rod moves downwards, the graduations can be visually displayed.

[0042] In this embodiment, rotating the rotary handle 800 can drive the rotating shaft 404 to rotate synchronously, thereby causing the permanent magnet 400 to rotate within the rotating cavity 300, realizing the switching between the first position and the second position. Two positioning plates 601 are respectively set corresponding to the first position and the second position. When the rotary handle 800 is rotated to either position, its handle will engage with the corresponding positioning plate 601, thus allowing a direct indication of whether the permanent magnet 400 has rotated to the correct position.

[0043] In this embodiment (not shown in the figure), a damping mechanism, such as a ball positioner or a ball plunger, is provided between the rotating shaft 404 and the housing 600. When the permanent magnet 400 rotates to the first position or the second position, the damping mechanism acts as a damper to prevent the rotating shaft 404 from rotating on its own, thus keeping the permanent magnet 400 in the first position or the second position.

[0044] In this embodiment, the rotating handle 800 can be detachably connected to the rotating shaft 404 through the mating structure of the plug post 801 and the plug slot 4041. The plug post 801 and the plug slot 4041 adopt a non-standard or irregular shape design, so that each handle can only match a unique rotating shaft 404. This structure effectively prevents unauthorized personnel from arbitrarily rotating the permanent magnet 400, enhancing the safety and exclusivity of operation.

[0045] In summary: This invention utilizes the cooperative arrangement of a first soft magnet 100, a second soft magnet 200, and a permanent magnet 400. When the permanent magnet 400, the first soft magnet 100, and the second soft magnet 200 form a magnetic circuit, the first soft magnet 100 and the second soft magnet 200 are magnetized. The magnetized first soft magnet 100 can then adhere to a steel pipeline, thereby quickly fixing the monitoring device to the pipeline. Conversely, when the permanent magnet 400 forms a magnetic short circuit with the first soft magnet 100 and / or the second soft magnet 200, the first soft magnet 100 and the second soft magnet 200 are demagnetized, allowing the monitoring device to be quickly removed from the pipeline. This magnetic connection method not only facilitates installation and disassembly, significantly improving installation efficiency, but also employs non-invasive installation, requiring only partial exposure of the pipeline for operation, significantly reducing construction risks and operating costs.

[0046] By making the first soft magnet 100 a flexible material, the adsorption surface 101 becomes deformable. When the radius of curvature of the adsorbed pipeline surface is greater than the radius of the adsorption surface 101, the adsorption surface 101 can expand adaptively; when the radius of curvature of the pipeline surface is smaller than the radius of the adsorption surface 101, the two sides of the adsorption surface 101 can contract and deform inward. This structure allows the adsorption surface 101 to automatically adjust its shape according to different pipe diameters, always maintaining a tight fit with the pipeline surface, significantly improving the adsorption stability and adaptability of the monitoring device.

[0047] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
