Description

Technical Field

[0001] This utility model relates to the field of pipeline connection structure technology, specifically a pipeline leak detection connection structure for urban pipelines. Background Technology

[0002] Urban pipelines refer to the pipelines and ancillary facilities within a city for water supply, drainage, gas, heating, electricity, communications, radio and television broadcasting, and industry. They are important infrastructure and "lifelines" for ensuring the operation of a city.

[0003] When detecting leaks in urban pipelines, various methods are used, including pressure monitoring, acoustic monitoring, and flow monitoring. Flow monitoring primarily compares the flow rates at the pipeline inlet and outlet. If the difference exceeds a certain range, a leak can be identified. During monitoring, flow monitoring valves need to be installed at both ends of the pipeline. However, most existing pipeline connections are integrated structures, fixedly installed with the flow valves. When the connection structure is damaged, the flow valves and associated pipelines need to be replaced, resulting in waste. Therefore, there is still room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a pipe connection structure for detecting leaks in urban pipelines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection structure for detecting leaks in urban pipelines, comprising a main pipeline, a flow valve installed on one side of the main pipeline, a split pipeline installed at the other end of the main pipeline, an external interface at the upper end of the main pipeline, a rotating shaft installed at the lower end of the main pipeline, a fixed plate installed at the lower end of the rotating shaft, an inner connecting plate fixedly installed at the lower end of the fixed plate, multiple pipe interfaces on the surface of the inner connecting plate, a pipe interface connected to the lower end of the split pipeline, and a pipe interface connected to the pipeline to be monitored at the other end of the split pipeline.

[0006] Preferably, the upper edge of the fixed plate is provided with multiple limiting holes, a lifting ring is slidably connected to the surface of the main pipe, and multiple limiting rods are installed at the lower end of the lifting ring. The positions and dimensions of the multiple limiting rods and the multiple limiting holes are mutually compatible.

[0007] Preferably, a reinforcing ring is fixedly installed on the surface of the main pipe at a position between the lifting ring and the fixed plate, and the surface of the reinforcing ring has multiple through holes that are slidably connected to the limiting rod.

[0008] Preferably, the surface of the main pipe is equipped with multiple guide slide rods, and the inner wall of the lifting ring is provided with multiple guide slide grooves. The positions and dimensions of the multiple guide slide rods and multiple guide slide grooves are all adapted to each other.

[0009] Preferably, a limiting ring is installed on the upper end of multiple guide slide rods, and the inner wall of the limiting ring is fixedly connected to the surface of the main pipe.

[0010] Preferably, the lower end of the split pipe is equipped with an installation flange, the size of which is compatible with the pipe interface, the upper end of the plurality of pipe interfaces is equipped with a first flange, and the lower end of the pipe interface is equipped with a second flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The pipe connection structure for leak detection in this city's pipeline connects both ends of the pipeline to be monitored to any pipe interface on the surface of an inner connection plate. Water enters through the external interface of the main pipeline, and the flow rate is recorded by the flow valve. Then, it enters the split pipeline through the main pipeline, and finally enters the pipeline to be monitored through the pipe interface of the fixed plate. It then flows out from the other end of the pipeline and sequentially passes through another inner connection plate and the split pipeline into another main pipeline. The flow rate is recorded again by the flow valve connected to the main pipeline. By comparing the results, the pipeline can be detected to detect whether a leak has occurred. If any pipe interface of the inner connection plate is damaged, the split pipeline can be rotated to connect to another intact pipe interface by rotating the shaft. At this time, the equipment can still operate normally without replacing the entire pipeline or the flow valve. The multiple pipe interfaces on the surface of the inner connection plate can increase the fault tolerance of the device and extend its service life to a certain extent.

[0013] 2. The pipe connection structure for leak detection in this city's pipelines uses multiple guide rods on the surface of the main pipeline. The lifting ring works in conjunction with the guide groove and guide rods, allowing the lifting ring to move up and down on the surface of the main pipeline. This, in turn, drives multiple limit rods to move up and down on the surface of the main pipeline. When the limit rod enters the limit hole, the position of the main pipeline and the position of the fixed plate will be relatively stable. At this time, the main pipeline cannot rotate. The lifting ring can be moved upward manually, causing the limit rod to disengage from the limit hole. Then, the main pipeline can rotate through the shaft. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the urban pipeline leak detection pipe connection structure in this embodiment includes a main pipeline 1, a flow valve 2 installed on one side of the main pipeline 1, and a split pipeline 3 installed at the other end of the main pipeline 1. The flow valve 2 and the split pipeline 3 are located on the left and right sides of the main pipeline 1, respectively. When water flows into the main pipeline 1 through the split pipeline 3, it is monitored by the flow valve 2. An external interface 4 is opened at the upper end of the main pipeline 1 for discharging water. A rotating shaft 16 is installed at the lower end of the main pipeline 1, and a fixed plate 9 is installed at the lower end of the rotating shaft 16. An inner connecting plate 5 is fixedly installed at the lower end of the fixed plate 9. The inner connecting plate 5 and the fixed plate 9 are fixedly connected. The rotating shaft 16 can rotate at the upper end of the fixed plate 9, thereby driving the main pipeline 1 to rotate. Multiple pipe interfaces 7 are opened on the surface of the inner connecting plate 5. The lower end of the split pipeline 3 is connected to one pipe interface 7, and the other end of the pipe interface 7 is connected to the pipeline to be monitored. The water inside the pipeline to be monitored will enter the interior of the split pipeline 3 through the pipe interface 7 and finally enter the interior of the main pipeline 1.

[0021] Specifically, the upper edge of the fixed plate 9 is provided with multiple limiting holes 15. A lifting ring 11 is slidably connected to the surface of the main pipe 1. Multiple limiting rods 17 are installed at the lower end of the lifting ring 11. The positions and dimensions of the multiple limiting rods 17 and the multiple limiting holes 15 are mutually compatible. A reinforcing ring 10 is fixedly installed on the surface of the main pipe 1, located between the lifting ring 11 and the fixed plate 9. The surface of the reinforcing ring 10 is provided with multiple through holes that are slidably connected to the limiting rods 17. Multiple guide rods 14 are installed on the surface of the main pipe 1. Multiple guide grooves 18 are provided on the inner wall of the lifting ring 11. The positions and dimensions of the multiple guide rods 14 and the multiple guide grooves 18 are mutually compatible. By setting multiple... A guide slide rod 14 and a lifting ring 11 are used in conjunction with a guide slide groove 18 to allow the lifting ring 11 to move up and down on the surface of the main pipe 1, thereby driving multiple limit rods 17 to move up and down on the surface of the main pipe 1. When the limit rod 17 enters the interior of the limit hole 15, the position of the main pipe 1 will be relatively stable with the position of the fixed plate 9. At this time, the main pipe 1 cannot rotate. The lifting ring 11 can be moved upward manually, so that the limit rod 17 is disengaged from the limit hole 15. At this time, the main pipe 1 can rotate through the rotating shaft 16. The reinforcing ring 10 and the limit rod 17 are slidably connected, which can form a certain protective effect on the outside of the limit rod 17.

[0022] Furthermore, a limiting ring 12 is installed on the upper end of multiple guide slide rods 14. The inner wall of the limiting ring 12 is fixedly connected to the surface of the main pipe 1. The limiting ring 12 can limit the maximum rising distance of the lifting ring 11.

[0023] Furthermore, the lower end of the split pipe 3 is equipped with an installation flange 6, which is compatible with the size of the pipe interface 7. The upper end of the multiple pipe interfaces 7 is equipped with a first flange 8, and the lower end of the pipe interface 7 is equipped with a second flange 13. The split pipe 3 is threadedly connected to the first flange 8 at the upper end of the pipe interface 7 through the installation flange 6, and the lower end of the pipe interface 7 is threadedly connected to the pipe to be monitored through the second flange 13.

[0024] The usage method of this embodiment is as follows: both ends of the pipe to be monitored are connected to any pipe interface 7 on the surface of an inner connecting plate 5. Water flows in through the outer interface 4 of the main pipe 1 and the flow rate is recorded by the flow valve 2. Then, it enters the interior of the split pipe 3 through the main pipe 1 and finally enters the interior of the pipe to be monitored through the pipe interface 7 of the fixed plate 9. It flows out from the other end of the pipe to be monitored and passes through another inner connecting plate 5 and the split pipe 3 in sequence to enter the interior of another main pipe 1. The flow rate is recorded again by the flow valve 2 connected to the main pipe 1. The comparison is used to detect whether the pipe is leaking. When any pipe interface 7 of the inner connecting plate 5 is damaged, the split pipe 3 can be rotated to the top of other intact pipe interfaces 7 by rotating the shaft 16. At this time, the equipment can still operate normally without replacing the entire pipe and the flow valve 2. The multiple pipe interfaces 7 on the surface of the inner connecting plate 5 can increase the fault tolerance of the device and increase its service life to a certain extent.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
