Technical Field
[0001] This utility model belongs to the field of pipeline leak detection technology, specifically a water supply network leak detection device. Background Technology
[0002] Water supply networks are an indispensable core infrastructure in modern cities. They are complex underground pipeline networks that safely, reliably, and continuously deliver tap water from water plants to households and various water-using units.
[0003] Over time, municipal water supply networks may develop small leaks due to pressure fluctuations or external loads. Regular inspections are necessary, typically using an electric leak detector to amplify the sound of leaks in buried pipes. When a leak occurs, high-pressure water sprays from the leak point, rubbing against the damaged area and impacting the surrounding medium, generating a specific frequency of vibration. The electric leak detector captures this weak vibration signal through sensors, amplifies it, and filters out some environmental noise, allowing inspectors to clearly hear the leak.
[0004] In the use of traditional power leakage detectors, inspectors usually rely on memory and notes to determine which sections have been inspected. When working over a large area, this can easily lead to sections being inspected repeatedly or being missed, resulting in repeated inspections of the same area and a decrease in inspection efficiency and accuracy.
[0005] Therefore, this utility model provides a water supply network leakage detection device. Utility Model Content

Detailed Implementation
[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1 to 5As shown in the embodiment of this utility model, a water supply network leakage detection device includes a sound pickup sensor 1; a cable 11 is installed on the top of the sound pickup sensor 1; a connecting wire 12 is installed in the middle of the sound pickup sensor 1; a control panel 13 is installed at the end of the connecting wire 12; a display screen 14 is provided in the middle of the control panel 13; a switch knob 15 is installed in the middle of the control panel 13; the switch knob 15 is located on one side of the display screen 14; a marking component 2 and a buffer component 3 are installed on the outer wall of the sound pickup sensor 1; a fixing component 4 is provided between the sound pickup sensor 1 and the cable 11; the marking component 2 includes a storage box 21; the storage box 21 is fixedly connected to... The outer wall of the pickup sensor 1; a feed inlet 22 is fixedly connected to the top of the storage box 21; a partition 23 is fixedly connected to the middle of the storage box 21; the bottom two sides of the partition 23 are set with slopes; two sets of discharge holes 24 are opened on the side wall of the partition 23; the two sets of discharge holes 24 are arranged oppositely; a stop block 25 is slidably connected to the middle of the partition 23; the stop block 25 is set in a trapezoidal shape; multiple sliding rods 26 are slidably intercepted at the bottom of the storage box 21; the ends of the multiple sliding rods 26 are fixedly connected to the bottom of the stop block 25; a pressure plate 28 is fixedly connected to the ends of the multiple sliding rods 26; multiple first springs 27 are fixedly connected to the middle of the pressure plate 28 and the bottom of the storage box 21; the first springs 27 are fixedly connected to the corresponding sliding rods 26. The rod 26 is external; the pressure plate 28 has multiple through slots 29 in the middle; during operation, the marking powder is placed inside the storage box 21 through the feed inlet 22 and stored in the storage box 21. When testing the water supply network, the sound pickup sensor 1 is first placed on the ground, and the buffer assembly 3 makes contact with the ground first, buffering the pressure plate 28 between it and the ground. Gravity makes the bottom of the sound pickup sensor 1 contact the ground. At this time, the pressure plate 28 under pressure causes multiple sliding rods 26 to slide at the bottom of the storage box 21. The first spring 27 elastically contracts, and the sliding of multiple sliding rods 26 pushes up the stop block 25, so that the stop block 25 is on the partition 23. The middle part slides, and when the stop block 25 moves upward, the powder leaks out from between the two sets of discharge holes 24 and falls to the ground. The powder marks the detection position. After the detection is completed, the pickup sensor 1 is pulled up through the cable 11. At this time, the elastic reset of the first spring 27 causes the stop block 25 to move downward, and the stop block 25 blocks the two sets of discharge holes 24. The above operation is repeated. The above structure can mark the detection position in real time. If the leak point needs to be checked later during the detection process, the powder mark can quickly guide the detection personnel to find the original detection position, reduce the need for large-scale re-detection operations, achieve accurate marking, and improve the overall detection efficiency.
[0020] like Figure 3 and Figure 4As shown, the buffer assembly 3 includes multiple first hinge seats 32; the first hinge seats 32 are installed at the bottom of the pressure plate 28; multiple grooves 31 are formed at the bottom of the pressure plate 28; the first hinge seats 32 are fixedly connected to the middle of the grooves 31; two buffer plates 33 are installed in the middle of the first hinge seats 32; the two buffer plates 33 are arranged opposite each other; elastic plates 34 are fixedly connected to the ends of the buffer plates 33; the ends of the elastic plates 34 are fixedly connected to the middle of the grooves 31; during operation, when testing, the ends of multiple sets of buffer plates 33 contact the ground, at which time the buffer plates 33 rotate in the middle of the first hinge seats 32, buffering... When the end of plate 33 is pressed, elastic plate 34 bends elastically, buffer plate 33 enters the groove 31, and pressure plate 28 contacts the ground. The elastic plate 34 elastically buffers the impact force between the pickup sensor 1 and pressure plate 28 when the pickup sensor 1 falls. The above structure reduces the direct impact of the bottom of the pickup sensor 1 on the rough road surface, effectively reducing the violent impact during the impact. Buffer plate 33 can effectively absorb and attenuate the energy generated by the impact, protecting the delicate sensing elements inside the pickup sensor 1, thereby extending the service life of the equipment and reducing maintenance costs.
[0021] like Figure 1 and Figure 5 As shown, the fixing assembly 4 includes two second hinge seats 41; the second hinge seats 41 are fixedly connected to the top of the pickup sensor 1; a connecting plate 43 is rotatably connected to the middle of the second hinge seats 41; a torsion spring 42 is installed between the connecting plate 43 and the second hinge seats 41; a clamping plate 44 is fixedly connected to the end of the connecting plate 43; the two clamping plates 44 are arranged opposite each other; an anti-slip strip 45 is fixedly connected to the inner side wall of the clamping plate 44; during operation, when the cable 11 is connected to the pickup sensor 1, the two clamping plates 44 are moved to both sides through the connecting plate 43, and after the cable 11 is connected to the pickup sensor 1, it is moved through... The torsion spring 42 causes the connecting plate 43 to rotate towards the center, and the end of the clamping plate 44 clamps the cable 11. The anti-slip strip 45 contacts the cable 11 and increases its friction. When the cable 11 is pulled to lift the pickup sensor 1, the pulling force is transmitted to the connecting plate 43 to keep the connection between the cable 11 and the pickup sensor 1 stable. The above structure can effectively reduce the friction between the cable 11 and the pickup sensor 1 caused by repeated lifting and pulling, reduce the loosening of the connection between the cable 11 and the pickup sensor 1 under vibration and tension, and reduce the frequency and cost of maintenance or replacement of parts due to loosening of the connection.
[0022] like Figure 1 As shown, a counterweight 5 is fixedly connected to the middle of the storage box 21; the counterweight 5 is fixedly connected to the outer wall of the storage box 21; during operation, the weight of the sound pickup sensor 1 is increased by the counterweight 5 during the detection process, so that the bottom of the sound pickup sensor 1 is in close contact with the ground during detection. The above structure enables the bottom of the sound pickup sensor 1 to better fit the rough road surface, reduce gaps and sound energy loss, make it easier for operators to identify and judge the leakage sound, and improve the reliability of the detection results.
[0023] like Figure 4 As shown, a wear-resistant pad 6 is estimated to be located in the middle of the buffer plate 33; the wear-resistant pad 6 is fixed to the end of the buffer plate 33; during operation, when the buffer plate 33 buffers the pressure plate 28, the wear-resistant pad 6 contacts the ground, reducing the friction between the buffer plate 33 and the ground. Through the above structure, the buffer plate 33 is reduced from repeated friction with the rough asphalt and concrete pavement, providing a durable and low-maintenance contact surface.
[0024] like Figure 3 As shown, the top of the partition 23 is sloped. When the marking powder is placed inside the storage box 21 during operation, the powder flows to both sides through the bottom of the partition 23. As the powder is used, it naturally slides to both sides. The above structure can effectively reduce the accumulation of powder on the top of the partition 23 during use, allowing the powder to fall naturally and reducing residue and waste.
[0025] During operation, the marking powder is placed inside the storage box 21 through the feed inlet 22 and stored there. When testing the water supply network, the sound pickup sensor 1 is first placed on the ground. The buffer assembly 3 makes contact with the ground first, and the pressure plate 28 is used to buffer the ground. Gravity causes the bottom of the sound pickup sensor 1 to contact the ground. At this time, the pressure plate 28 causes multiple sliding rods 26 to slide at the bottom of the storage box 21. The first spring 27 elastically contracts, and the sliding rods 26 push up the stop block 25, so that the stop block 25 is in the isolation... The middle of plate 23 slides. When the stop block 25 moves upward, the powder leaks out from between the two sets of discharge holes 24 and falls to the ground. The powder marks the detection position. After the detection is completed, the pickup sensor 1 is pulled up through the cable 11. At this time, the first spring 27 elastically resets and causes the stop block 25 to move downward, blocking the two sets of discharge holes 24. The above operation is repeated. During detection, the ends of multiple buffer plates 33 are in contact with the ground. At this time, the buffer plates 33 rotate in the middle of the first hinge seat 32. When the ends of the buffer plates 33 are pressed, the elastic plate 34 bends elastically. The buffer plate 33 enters the groove 31, and the pressure plate 28 contacts the ground. The elastic plate 34 elastically buffers the impact force between the pickup sensor 1 and the pressure plate 28 when the pickup sensor 1 falls. When the cable 11 is connected to the pickup sensor 1, the two clamping plates 44 are moved to both sides through the connecting plate 43. After the cable 11 is connected to the pickup sensor 1, the connecting plate 43 is rotated to the center by the torsion spring 42. The end of the clamping plate 44 clamps the cable 11. The anti-slip strip 45 contacts the cable 11 and increases its friction. When the cable 11 is pulled, the pickup sensor 1 is activated. When sensor 1 is lifted upwards, the pulling force is transmitted to the connecting plate 43, keeping the connection between cable 11 and the pickup sensor 1 stable. During the detection process of pickup sensor 1, the weight of pickup sensor 1 is increased by counterweight block 5, so that the bottom of pickup sensor 1 is in close contact with the ground during detection. When buffer plate 33 buffers pressure plate 28, wear-resistant pad 6 contacts the ground, reducing friction between buffer plate 33 and the ground. When the marking powder is placed inside storage box 21, the powder flows to both sides through partition 23, and the powder naturally slides to both sides as it is used.
