Description

Technical Field

[0001] This utility model relates to a seepage prevention detection device for water conservancy pipelines, belonging to the field of water conservancy pipelines. Background Technology

[0002] Water conservancy projects, as core infrastructure for regulating surface water and groundwater and achieving the goals of mitigating harm and promoting benefits, play an irreplaceable role in ensuring the rational allocation of water resources, preventing floods and droughts, and supporting industrial and agricultural production and residential water use. They have formed a systematic theoretical and engineering practice framework. With the continuous increase in societal demand for water resource security, the construction scale and operation and maintenance standards of water conservancy projects are constantly improving. Pipelines, as the key carriers for water transport in water conservancy projects, directly determine the efficiency of the entire water conservancy system through their operational stability.

[0003] During the long-term operation of water conservancy pipeline systems, pipeline joints, especially those connected by flanges, become high-risk areas for leakage due to the long-term effects of water pressure, media corrosion, temperature changes, and foundation settlement. Currently, the industry mostly adopts a periodic inspection model for pipeline operation and maintenance. However, due to limitations in the pipeline laying environment (such as underground burial, deep burial in dams or tunnels), the limitations of detection technology, and the small amount of water in the initial stage of leakage that is easily concealed by the environment, early leakage problems at pipeline joints are often difficult to detect in a timely manner.

[0004] This situation, where leaks are difficult to detect and faults are difficult to locate, leads to pipe joints remaining in a state of hidden leakage for a long time. On the one hand, continuous leakage will cause ineffective waste of water resources, which is contrary to the requirements of building a water-saving society. On the other hand, leakage will change the hydraulic environment around the pipe, causing the corrosion of the inner wall of the pipe to intensify and the aging of the sealing structure of the joint to accelerate. This will lead to fluctuations in the water flow pressure in the pipe, which will not only affect the efficiency of water transportation, but may also cause secondary disasters such as pipe rupture and soil subsidence in severe cases, threatening the overall safe operation of water conservancy projects.

[0005] Therefore, in view of the problems of difficulty in detecting leakage at the connection of existing water conservancy pipelines and the lack of timely detection, there is an urgent need to develop a leakage detection device with a simple structure, convenient installation, and the ability to capture early leakage signals in real time and accurately. This device can make up for the shortcomings of traditional inspection methods, realize early detection and early treatment of pipeline leakage, and ensure the stable and efficient operation of water conservancy pipeline systems. Utility Model Content

[0006] The purpose of this invention is to provide a water conservancy project pipeline anti-leakage detection device to solve the above-mentioned problems.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a water conservancy project pipeline anti-leakage detection device, including a first pipeline, a second pipeline, a leakage detection component, and an auxiliary disassembly component. The second pipeline corresponds to the first pipeline, and a connecting flange is provided at the interface between the first pipeline and the second pipeline. The leakage detection component is located outside the connecting flange, and the auxiliary disassembly component is installed outside the leakage detection component.

[0008] Preferably, the arc-shaped plate is consistent with the circumference diameter of the pipe, and the leakage detection component includes a first arc-shaped plate and a second arc-shaped plate. The first arc-shaped plate is located on the upper part of the connecting flange, and the second arc-shaped plate is located on the lower part of the connecting flange.

[0009] Preferably, the arc-shaped frame is fitted to the outside of the connecting flange, and at the same time, it can collect the water leakage when there is water leakage at the connecting flange, making it easy for maintenance personnel to find and repair. The second arc-shaped plate has an arc-shaped frame inside, and the arc-shaped frame is in contact with the lower part of the connecting flange.

[0010] Preferably, the guide tube is designed to guide the water droplets within the arc-shaped frame, and the guide tube slides between the inner and outer walls of the second arc-shaped plate, with the upper part of the guide tube fixedly connected to the lower part of the arc-shaped frame.

[0011] Preferably, water droplets fall into the circular opening within the curved frame, and the circular opening is located at the top of the guide tube.

[0012] Preferably, the spring is provided as an auxiliary effect to make the arc frame fit better with the connecting flange. The guide tube is fitted with a spring on the outside, and the spring is located between the arc frame and the second arc plate. A humidity sensor is provided at the lower part of the second arc plate, and the connector of the humidity sensor is fixedly connected to the other end of the guide tube.

[0013] Preferably, the auxiliary disassembly assembly enables the first arc-shaped plate and the second arc-shaped plate to be installed conveniently. The auxiliary disassembly assembly includes a first mounting plate and a second mounting plate. The first mounting plate is fixedly installed on the outside of the first arc-shaped plate, and the second mounting plate is fixedly installed on the outside of the second arc-shaped plate. A square insert is fixedly installed on the lower part of the first mounting plate.

[0014] Preferably, when the pull rod is pulled, it can disengage the limiting rod from the limiting groove. As the limiting rod disengages, the square rod can disengage from the square slot, thereby allowing the first arc plate and the second arc plate to be separated. The upper part of the second mounting plate has a square groove, and the square rod is inserted into the square groove. A limiting rod is fixedly installed on the outside of the second mounting plate, and a pull plate slides on the outside of the limiting rod. Limiting grooves are opened inside both the square rod and the second mounting plate, and the limiting rod slides inside the limiting groove. One end of the limiting rod is fixedly connected to the outside of the pull plate. A torsion spring is provided on the outside of the limiting rod, and a circular block is fixedly installed on one end of the limiting rod.

[0015] The beneficial effects of this utility model are: 1. The installed leakage detection component, with the help of arc-shaped flow guide and sensor, helps inspectors to detect water leakage in a timely manner, thereby alleviating the problem that the connection is in a state of leakage for a long time due to the pipeline not being inspected for a long time, which leads to unstable pressure in the pipeline.

[0016] 2. The auxiliary disassembly component, through its locking mechanism, allows the first and second arc-shaped plates to be separated, facilitating maintenance and alleviating the difficulty of loosening multiple screws. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figures 1-6 As shown, a water conservancy project pipeline seepage prevention detection device includes a first pipeline 1, a second pipeline 4, a seepage detection component 2, and an auxiliary disassembly component 3. The second pipeline 4 corresponds to the first pipeline 1. A connecting flange 5 is provided at the interface between the first pipeline 1 and the second pipeline 4. The seepage detection component 2 is located outside the connecting flange 5. The auxiliary disassembly component 3 is installed outside the seepage detection component 2.

[0026] like Figures 1-6As shown, the leakage detection component 2 includes a first arc-shaped plate 201 and a second arc-shaped plate 202. The first arc-shaped plate 201 is disposed on the upper part of the connecting flange 5, and the second arc-shaped plate 202 is disposed on the lower part of the connecting flange 5. An arc-shaped frame 203 is disposed inside the second arc-shaped plate 202, and the arc-shaped frame 203 is in close contact with the lower part of the connecting flange 5. A guide tube 204 slides between the inner and outer walls of the second arc-shaped plate 202. The upper part of the guide tube 204 is fixedly connected to the lower part of the arc-shaped frame 203. A circular opening 205 is provided inside the arc-shaped frame 203. 05 is located at the upper part of the guide tube 204. A spring 206 is sleeved on the outside of the guide tube 204. The spring 206 is located between the arc-shaped frame 203 and the second arc-shaped plate 202. A humidity sensor 207 is installed at the lower part of the second arc-shaped plate 202. The connector of the humidity sensor 207 is fixedly connected to the other end of the guide tube 204. When installing, the user places the first arc-shaped plate 201 on the connecting flange 5, and then fits the second arc-shaped plate 202 against the lower part of the connecting flange 5, so that the first arc-shaped plate 201 and the second arc-shaped plate 202 correspond to each other. Pulling the pull plate 308 causes the limiting rod 306 to move, allowing the square rod 303 to be positioned within the square groove 304. As the square rod 303 is inserted, releasing the pull plate 308 allows it to reset under the influence of the torsion spring 307. This reset of the pull plate 308 causes the limiting rod 306 to insert into the limiting groove, thus resetting the square rod 303 and the first arc-shaped plate 201. This allows the first arc-shaped plate 201 and the second arc-shaped plate 202 to be mounted on the connecting flange 5. In addition, when water seepage occurs in the pipeline after long-term use, the water flows downward due to gravity. As the water flows into the arc-shaped frame 203, it flows downward through the circular opening 205 due to the angle of the arc plate and finally drips into the guide pipe 204. As the water droplets fall, the humidity sensor 207 can detect the pipeline leak immediately, making it easier for the inspector to detect the water seepage in time. This alleviates the problem of unstable pressure in the pipeline caused by the pipeline not being inspected for a long time and the water seepage being difficult to detect.

[0027] like Figures 1-5As shown, the auxiliary disassembly assembly 3 includes a first mounting plate 301 and a second mounting plate 302. The first mounting plate 301 is fixedly mounted on the outside of the first arc-shaped plate 201, and the second mounting plate 302 is fixedly mounted on the outside of the second arc-shaped plate 202. A square insert rod 303 is fixedly mounted on the lower part of the first mounting plate 301, and a square groove 304 is formed on the upper part of the second mounting plate 302. The square insert rod 303 is inserted into the square groove 304. A limit rod 305 is fixedly mounted on the outside of the second mounting plate 302, and a pull plate 308 slides on the outside of the limit rod 305. Limiting plates are formed inside both the square insert rod 303 and the second mounting plate 302. The limiting groove has a sliding limiting rod 306 inside. One end of the limiting rod 306 is fixedly connected to the outside of the pull plate 308. A torsion spring 307 is provided on the outside of the limiting rod 305. A circular block is fixedly installed on one end of the limiting rod 305. At the same time, when it is necessary to repair the water leakage of the connecting flange 5, pulling the pull plate 308 can make the limiting rod 306 disengage from the limiting groove. As the limiting rod 306 disengages, the square rod 303 can disengage from the square slot, thereby allowing the first arc plate 201 and the second arc plate 202 to be separated, which is convenient for maintenance personnel to carry out maintenance and alleviates the trouble of needing to disassemble and loosen multiple screws.

[0028] When this utility model is in use, if water seepage occurs in the pipeline after prolonged use, the seepage water flows downwards due to gravity. As the seepage water flows into the arc-shaped frame 203, it flows downwards through the circular opening 205 due to the angle of the arc plate and finally drips into the guide pipe 204. As the water droplets fall, the humidity sensor 207 can detect the pipeline leak immediately, making it easier for the inspector to detect the seepage in time. This alleviates the problem of unstable pressure in the pipeline caused by the pipeline not being inspected for a long time and the seepage being difficult to detect.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
