Description

Technical Field

[0001] This utility model relates to the field of gas pipeline installation and monitoring technology, specifically to a stray current monitoring device for gas pipelines. Background Technology

[0002] Gas pipelines refer to pipelines primarily used for transporting natural gas, liquefied petroleum gas, and manufactured gas. In long-distance transportation, gas pipelines specifically refer to those transporting natural gas. In urban areas, they refer to those transporting natural gas, liquefied petroleum gas, and manufactured gas, among other media. Due to the special nature of their transport, pipeline materials used in gas pipelines exposed to the elements for extended periods are prone to generating stray currents, requiring monitoring to prevent safety accidents.

[0003] For example, a stray current monitoring device for gas pipelines, with application number CN202222448294.7 and authorization announcement date of 20230324, includes a main mounting plate and a monitoring sensor body. A top mounting support foot is fixedly mounted on the top of the rear side wall of the main mounting plate, and a bottom mounting support foot is fixedly mounted on the bottom of the rear side wall of the main mounting plate. This utility model has a reasonable design; the entire device can be installed on a wall or outside a pipeline. It connects the device to the pipeline using a current line. The two sets of mounting support feet improve the overall stability of the device installation and prevent damage from external forces. If stray current occurs, the current sensing pointer at the front end will deflect, and the data is transmitted to the operator via a data transmitter on the top of the device, allowing them to be aware of the situation immediately. This device provides real-time stray current monitoring.

[0004] Traditional stray current monitoring devices lack terrain adaptability in their installation structure, making it difficult to adapt to different pipe diameters or complex terrains. Furthermore, their stability relies on rigid support feet, making them prone to displacement when subjected to external impacts. Therefore, there is an urgent need to design a stray current monitoring device for gas pipelines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a stray current monitoring device for gas pipelines to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stray current monitoring device for gas pipelines includes an installation assembly and a testing assembly. The installation assembly includes a mounting base, a folded rubber block bolted to the bottom of the mounting base, and a pad bolted to the bottom of the folded rubber block. A rope is bolted to one outer wall of the mounting base, and a fixing base is bolted to the other outer wall of the mounting base. A winding rod is mounted inside the fixing base via a bearing. A groove is inserted into one outer wall of the winding rod, and one end of the rope is inserted into the groove. A handle is bolted to one end of the winding rod, and a ratchet is bolted to the other end. A support plate is integrally formed on one outer wall of the fixing base, and a pawl is hinged to one outer wall of the fixing base, with one end of the pawl engaging the ratchet. A connecting spring is bolted to one outer wall of the pawl, and the other end of the connecting spring is bolted to the support plate.

[0008] Furthermore, the test component includes a mounting base, the top of which has a mounting groove, and a T-shaped metal rod is slidably inserted into the mounting groove.

[0009] Furthermore, the bottom of the inner wall of the mounting groove is bolted to the lower spring, and the top of the lower spring is bolted to the T-shaped metal rod, the bottom end of the T-shaped metal rod passing through the lower spring.

[0010] Furthermore, a mounting cylinder is bolted to the top of the mounting base, and an upper spring is bolted to the bottom of the mounting cylinder. The bottom of the upper spring is bolted to the top of the T-shaped metal rod.

[0011] Furthermore, the mounting cylinder is equipped with a communication and battery module and a detection module arranged in an upper and lower structure. The communication and battery module is electrically connected to the detection module through wires, and the detection module is electrically connected to the T-shaped metal rod by a connecting wire.

[0012] Furthermore, the top of the mounting cylinder is threadedly connected to a cylinder cap, and a handle is bolted to the center of the top of the cylinder cap.

[0013] Furthermore, the mounting base has an installation area at its top, and the mounting base is installed inside the installation area by bolts.

[0014] In the above technical solution, the stray current monitoring device for gas transmission pipelines provided by this utility model has the following advantages:

[0015] (1) This utility model achieves adaptive installation of the device for different pipe diameters and complex terrains by combining the design of folded rubber blocks and adjustable ropes, and with the ratchet and pawl locking mechanism. The structure formed by the folded rubber blocks and pads can fit the irregular pipe surface, the rope winding mechanism provides flexible constraint force, and the ratchet and pawl structure ensures resistance to external impact after fastening, thus solving the problem of easy displacement of traditional rigid support feet.

[0016] (2) This utility model adopts a bidirectional spring structure consisting of a T-shaped metal rod and a lower spring and an upper spring, so that the detection electrode is always dynamically pressed against the pipe surface. In this process, the elastic compensation mechanism of the upper and lower springs can absorb the displacement caused by equipment vibration or pipe deformation, buffer external vibration or displacement impact, avoid poor contact caused by long-term vibration in the traditional direct connection method, ensure the continuity of current signal acquisition, and avoid measurement errors or component damage caused by traditional rigid connection.

[0017] (3) This utility model achieves rapid opening and closing through the threaded cylinder cover, allowing for individual battery replacement or repair of the testing unit without the need for overall equipment disassembly, significantly reducing maintenance costs and time, overcoming the shortcomings of traditional modularity, and the bolted connection design between the installation area and the mounting base enables rapid separation and integration of the testing components and the installation components. This split structure facilitates transportation and partial replacement, while mechanical fastening ensures overall stability, comprehensively improving the reliability and service life of the monitoring system.

During operation, the T-shaped metal rod 23 serves as the detection electrode, transmitting stray current from the pipeline to the detection module 21 via the connecting wire 26. The module converts the analog signal into digital data, which is then uploaded to the cloud by the communication and battery module 20.

During subsequent maintenance, the cylinder cover 18 can be removed by rotating the handle 19, allowing for the replacement of either the communication and battery module 20 or the detection module 21. The test component 2 and the installation component 1 can be separated by removing the bolts in the installation area 4.
