[0002] In modern urban drainage pipe network systems, pipe leakage has increasingly become a key factor affecting network safety and water waste. With the acceleration of urbanization, problems such as aging, damage and blockage of drainage pipe networks are constantly emerging, and leakage is particularly common. This not only increases the difficulty of drainage pipe network maintenance, but may also cause serious environmental pollution problems. Therefore, how to effectively detect and locate leaks in drainage pipe networks and repair pipes in a timely manner has become a technical problem that urgently needs to be solved in municipal engineering.

[0003] Currently, the detection technology for leaks in drainage pipe networks mainly relies on methods such as acoustic detection, gas detection, and visual detection. However, these traditional technologies have certain limitations, such as requiring a high degree of human intervention or being greatly affected by environmental interference, resulting in low detection efficiency and insufficient positioning accuracy.

[0026] 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.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a positioning device for detecting leaks in drainage pipe networks, comprising a mounting sleeve 1. Rollers 2 are evenly rotatably connected around the center of the mounting sleeve 1. A drainage pipe network is located on one side opposite to each roller 2. Sensors 3 are evenly fixedly connected to the front inner wall of the mounting sleeve 1. Connecting blocks 7 are fixedly connected to the top and bottom of the front side of the mounting sleeve 1. A connecting rope 8 is fixedly connected to the front of the connecting blocks 7. A traction component is provided at the end of the connecting rope 8 away from the connecting blocks 7 for traction of the mounting sleeve 1. The traction component includes a connecting rod 9, which is fixedly connected to the end of the connecting rope 8 away from the connecting blocks 7. The outer side of the connecting rod 9 is rotatably connected to... A mounting bracket 10 is attached, with a handle 11 fixedly connected to the front side of the mounting bracket 10. A connecting plate 12 is fixedly connected to the lower part of the connecting rod 9, and a throttle 13 is fixedly connected to the lower right side of the connecting plate 12. Both ends of the connecting rod 9 pass through the mounting bracket 10. A marking component is provided on the upper rear side of the inner wall of the mounting sleeve 1 for marking the location of leaks in the drainage pipe network. The marking component includes a storage box 4, which is fixedly connected to the upper rear side of the inner wall of the mounting sleeve 1. A discharge pipe 5 is fixedly connected to the lower rear side of the storage box 4, and a metering valve 6 is fixedly connected to the outside of the discharge pipe 5. The sensor 3 is electrically connected to the metering valve 6. Paint is provided inside the storage box 4.

[0028] When performing leak detection in drainage pipe networks, the handle 13 is first turned to rotate the connecting plate 12, which in turn drives the connecting rod 9 to rotate. The rotation of the connecting rod 9 further drives the connecting rope 8 to wind up. The connecting rope 8 pulls the mounting sleeve 1 to move through the connecting block 7. The mounting sleeve 1 drives the roller 2 to move along the path on the surface of the pipe network. During this process, the sensor 3 detects the state of the surface of the drainage pipe network in real time. When the sensor 3 detects a leak on the surface of the drainage pipe network, it automatically controls the opening of the metering valve 6, so that the paint in the storage box 4 is evenly discharged through the discharge pipe 5, thereby accurately marking the leak location. This can efficiently complete leak detection, automatically locate the leak point, improve the efficiency and accuracy of leak detection in drainage pipe networks, and ensure the timely repair and maintenance of the pipe network system.

[0029] Reference Figures 1-3 The mounting sleeve 1 is made of aluminum alloy, the roller 2 is made of engineering plastic, and the connecting rope 8 is made of stainless steel.

[0030] The use of aluminum alloy material ensures the durability and lightweight of the mounting sleeve 1, making the positioning device easier to operate. The use of engineering plastic material reduces the friction of the roller 2, ensuring that the roller 2 can move smoothly on the surface of the drainage pipe network, reducing wear and extending service life. The use of stainless steel material ensures the strength of the connecting rope 8, ensuring that the connecting rope 8 can withstand a large load during the entire detection process without easily breaking. This improves the durability of the positioning device for detecting leaks in drainage pipe networks, enabling it to maintain excellent performance in long-term use.

[0031] Working principle: When leakage detection of the drainage pipe network is required, the handle 13 is turned to make the connecting plate 12 rotate. The connecting plate 12 drives the connecting rod 9 to rotate. The rotation of the connecting rod 9 winds up the connecting rope 8. The connecting rope 8 pulls the mounting sleeve 1 to move through the connecting block 7. The mounting sleeve 1 drives the roller 2 to move on the surface of the drainage pipe network. The sensor 3 detects the surface of the drainage pipe network. When the sensor 3 detects a leak on the surface of the drainage pipe network, it controls the opening of the metering valve 6, so that the paint in the storage box 4 is discharged through the discharge pipe 5 to mark the drainage pipe network. This realizes that the positioning device for leakage detection of the drainage pipe network can automatically mark the leakage location of the drainage pipe network, improving the efficiency of leakage detection of the drainage pipe network.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
