Description

Technical Field

[0001] The utility model relates to the technical field of buried pipeline protection, in particular to a distributed drainage prevention and control and repair device for urban gas pipelines. Background Technique

[0002] With the rapid development of the energy industry and the transportation industry, large-scale construction of infrastructure such as high-speed electrified railways and buried oil and gas pipelines has been carried out, forming a complex and widespread energy transmission network and transportation network across the country. Due to the limitations of space resources and geographical environment, high-speed electrified railways and buried steel pipelines often run parallel or cross over a long distance in the "public corridor", making the problem of stray current interference faced by the pipelines very serious. There have been many reported cases of perforation and leakage caused by stray current corrosion of electrified railways at home and abroad.

[0003] In the urban gas supply system, the safe and stable operation of gas pipelines is of crucial importance. With the continuous advancement of urban construction and the increasing complexity of various infrastructure, the protection requirements for gas pipelines are also getting higher and higher. At present, common AC mitigation measures include laying horizontal zinc strip ground beds, deep well drainage ground beds, and grounding grid ground beds along the pipelines. However, in urban areas, due to geographical location limitations, the use of these ground bed forms is restricted to a certain extent. For example, some drainage points are close to roads and hardened buildings, with very little land area, and only deep well drainage technology can be used to mitigate AC interference. However, the construction of deep well ground beds is complex and requires a large amount of funds; there are many electrified devices intermittently along some pipelines, and the conditions for laying long-distance horizontal zinc strips or large-area grounding grids are not available. Distributed mitigation ground beds are suitable. For the dynamic AC interference generated by high-speed electrified railways, considering the difficulties of excavation in the urban environment and the lack of cathodic protection for urban gas pipelines, magnesium sacrificial anodes can be used to protect the pipeline safety.

[0004] In the prior art, urban gas pipelines are usually equipped with test piles for detecting and monitoring relevant parameters. However, the test lines inside the test piles often lack effective positioning mechanisms, which makes the test lines randomly placed and disorderly inside the piles. This situation is not only inconvenient for management and maintenance, but also easily leads to entanglement and interference between the test lines, affecting the accuracy and reliability of test data. Therefore, we need to propose a distributed drainage prevention and control and repair device for urban gas pipelines. Content of the Utility Model

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the utility model provides a distributed drainage prevention and control repair device for urban gas pipelines, which includes a test pile 1 and several groups of anode pits 2. Sacrificial anode parts 3 are respectively arranged inside the several groups of anode pits 2. The test pile 1 includes a column 101 and a test box 102. The test box 102 is fixedly installed on one side wall of the column 101. Two wiring boards 11 are arranged inside the test box 102. Two positioning components 4 for clamping test wires are respectively arranged on one side walls of the two wiring boards 11. Two fixing plates 5 are fixedly installed on one inner wall of the test box 102. Positioning blocks 6 are respectively fixedly installed on the tops of the two wiring boards 11.

[0023] A clamping component 7 for cooperating with the fixing plate 5 to position the wiring board 11 is arranged on the positioning block 6. By arranging the wiring board 11 inside the test box 102 and arranging the positioning component 4 on one side of the wiring board 11, the test wire harness inside the test box 102 can be clamped and positioned, thereby avoiding the mutual entanglement and interference between multiple strands of test wire cables, which is beneficial to improving the accuracy and reliability of test data. By setting the cooperation of the fixing plate 5, the positioning block 6 and the clamping component 7, the height of the wiring board 11 inside the test box 102 can be adjusted, which can flexibly adapt to different wiring requirements, and adjust the wiring board 11 to the most suitable height according to the actual situation, making the wiring layout more reasonable and orderly, and avoiding the chaos of wiring.

[0024] The positioning component 4 includes two mounting plates 401. The two mounting plates 401 are both fixedly installed on one side wall of the wiring board 11. Guide cylinders 402 are fixedly embedded inside the two mounting plates 401. Movable rods 403 are respectively slidably inserted inside the two guide cylinders 402. One ends of the two movable rods 403 are respectively fixedly connected with wire clamping blocks 404. The other ends of the two movable rods 403 are respectively fixedly connected with telescopic springs 405. One ends of the two telescopic springs 405 are respectively fixedly connected with one side inner walls of the two guide cylinders 402.

[0025] Specifically, after the connected test wire harness passes through between the two wire clamping blocks 404, the outer wall of the harness will squeeze the two wire clamping blocks 404, thereby driving the telescopic spring 405 to be compressed. At this time, the resilience of the telescopic spring 405 is used to drive the two wire clamping blocks 404 to clamp and position the test wire harness, thereby avoiding the mutual entanglement and interference between multiple strands of test wire cables, which is beneficial to improving the accuracy and reliability of test data.

[0026] The positioning component 4 further includes a V-shaped groove 406. The V-shaped groove 406 is opened on one side wall of the wire clamping block 404, and the two V-shaped grooves 406 are arranged oppositely. By arranging the V-shaped groove 406, the test wire harness can be clamped more tightly, which is beneficial to improving the clamping stability.

[0027] On one side wall of the flexible cable board 11, two groups of sliders 8 are fixedly connected. On one inner wall of the test box 102, two groups of limit plates 9 are fixedly installed. On one side wall of the limit plate 9, a chute 10 adapted to the slider 8 is opened. The slider 8 is slidably connected to the inside of the chute 10. By setting the cooperation of the slider 8, the limit plate 9 and the chute 10, the flexible cable board 11 can be adjusted in height in the vertical direction.

[0028] The clamping component 7 includes an installation sleeve 701, which is fixedly embedded in the positioning block 6. A locking rod 702 is slidably inserted into the inside of the installation sleeve 701. One end of the locking rod 702 is inserted into the inside of the fixed plate 5, and the other end of the locking rod 702 is fixedly connected to a pull plate 703.

[0029] The clamping component 7 further includes a return spring 704. One end of the return spring 704 is fixedly connected to one side wall of the pull plate 703, and the other end of the return spring 704 is fixedly connected to one end of the installation sleeve 701. And the return spring 704 is movably sleeved on the outer wall of the locking rod 702. On one side of the positioning block 6, a number of positioning blind holes adapted to one end of the locking rod 702 are also opened.

[0030] By adopting the above case, after the height of the flexible cable board 11 is adjusted, the flexible cable board 11 can be locked and positioned by the clamping component 7. Specifically, first pull the pull plate 703, which can drive the locking rod 702 to move. At this time, the return spring 704 is in a stretched state. At this time, slide the flexible cable board 11 to adjust the height. When the locking rod 702 is aligned with the corresponding positioning blind hole, then release the pull plate 703, and use the pulling force of the return spring 704 to firmly insert one end of the locking rod 702 into the inside of the positioning blind hole, so as to achieve the effect of adjusting and locking the height of the flexible cable board 11, which can flexibly adapt to different cable laying requirements, adjust the flexible cable board to the most suitable height according to the actual situation, make the cable layout more reasonable and orderly, and avoid the chaos of cables.

[0031] The sacrificial anode member 3 is set as a magnesium anode, and the sacrificial anode member 3 is buried horizontally. The anode pit 2 is excavated by the open excavation method of manual excavation. A total of 10 working pits with a length × width × depth of 1.2m × 1m × 0.8m are excavated. 10 pre-packaged magnesium anodes are used. The magnesium anodes are buried horizontally. The magnesium anodes are placed in the already excavated anode pits, and one magnesium anode is placed every 1.5m. The 10 magnesium anodes are connected into the test box 102 through a test wire passing through the column 101 and are connected to the pipeline through the test box 102. It should be noted that the column 101 is hollow, and a positioning component 4 for clamping the test wire harness is also arranged inside it.
