Description

Technical Field

[0001] This utility model relates to the field of water supply pipe leakage detection technology, specifically to a water supply pipe leakage detection device. Background Technology

[0002] Water supply pipes are a type of green, energy-saving, and environmentally friendly pipe material. They do not rust, scale, or shrink in diameter, have low fluid resistance, and can effectively reduce water supply energy consumption and increase water supply at water points. They are an ideal pipe for pipe networks. However, during the installation of water supply pipes, it is necessary to use a testing device to check their sealing performance to prevent leaks.

[0003] Existing water supply pipe leak detection devices first seal both ends of the pipe and pressurize its interior. Then, a worker moves a handheld acoustic sensor across the pipe surface to detect the hissing sound produced at the leak point. However, this method has limitations. The leak location is random and uncertain, and the acoustic sensor can only be positioned on the side of the pipe, resulting in a limited detection range. It cannot comprehensively detect the pipe's sidewalls, leading to low detection accuracy and poor performance. Therefore, a new water supply pipe leak detection device is urgently needed to solve these problems. Utility Model Content

Simultaneously, the movement of the water supply pipe allows for comprehensive testing, ensuring the detection accuracy of the acoustic sensor, improving its detection effect, and providing high performance.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-4 As shown, a water supply pipe leakage detection device in this embodiment includes a storage box 1 for storing detection auxiliary tools. A detection frame 2 is fixed to the upper end of the storage box 1. A detection box 4 is installed in the middle of the upper end of the detection frame 2. A rotating ring 6 is installed inside the detection box 4, which can drive the acoustic sensor 10 to rotate. Tooth blocks 14 are distributed circumferentially on the outer wall of the rotating ring 6. A drive gear 15 is connected to one side of the tooth blocks 14, which can drive the rotating ring 6 to rotate. A servo motor 5 is installed on the drive gear 15, which can drive the drive gear 15 to rotate. An acoustic sensor 10 is fixed to one side of the inner wall of the rotating ring 6, which can detect the hissing sound emitted by the leakage point. A controller 12 is set on one side of the acoustic sensor 10, and a buzzer 13 is installed on one side of the controller 12. When the hissing sound is detected, the buzzer 13 is controlled by the controller 12 to work and remind the staff. A charging port 11 is set on the other side of the acoustic sensor 10. The rotating ring 6 has a built-in battery to provide the required power to the detection mechanism.

[0025] like Figures 1-4In this embodiment, the detection frame 2 is fixed to the top of the storage box 1 with screws. Two sets of bearing rollers 3 are symmetrically rotated on both sides of the upper end of the detection frame 2. The rotating ring 6 is rotatably installed inside the detection box 4. The toothed block 14 is connected to the rotating ring 6 with screws. The drive gear 15 meshes with the toothed block 14. The output shaft of the servo motor 5 is fixedly connected to the toothed block 14. The servo motor 5 is fixed to one side wall of the detection box 4 with bolts. The servo motor 5 has a reserved start / stop key. The acoustic sensor 10 is electrically connected to the controller 12. The controller 12 is electrically connected to the buzzer 13. The acoustic sensor 10, the controller 12, and the buzzer 13 are all fixed to one side wall inside the rotating ring 6 with screws. During the airtightness test of the water supply pipe, the pressurized water supply pipe is passed through the rotating ring 6 and moved. During the movement, the servo motor 5 drives the drive gear 15 to rotate, and the drive gear 15 drives the rotating ring 6 to rotate through the tooth block 14, which in turn drives the acoustic sensor 10 to rotate around the outside of the water supply pipe, changing the detection position of the acoustic sensor 10. At the same time, in conjunction with the movement of the water supply pipe, the water supply pipe can be fully inspected. When the acoustic sensor 10 detects a hissing sound from a leak point, the controller 12 controls the buzzer 13 to work to remind the staff. This ensures the detection accuracy of the acoustic sensor 10, improves its detection effect, and has high performance.

[0026] like Figures 1-4 In this embodiment, a sealing cover 7 is provided on one side wall of the storage box 1 via a slot. An air pump 9 is placed inside the storage box 1, and an air pipe 8 is provided on one side of the air pump 9. Connecting nozzles are reserved at both ends of the air pipe 8.

Then, the air pump 9 is connected to an external power source, and one end of the air pipe 8 is connected to the air pump 9, while the other end is connected to a water supply pipe. The other end of the water supply pipe is sealed with a corresponding sealing plug. Then, the air pump 9 pressurizes the inside of the water supply pipe, and the pressurized water supply pipe is passed through the rotating ring 6 and... The servo motor 5 drives the drive gear 15 to rotate during the movement. The drive gear 15 drives the rotating ring 6 to rotate through the tooth block 14, which in turn drives the acoustic sensor 10 to rotate around the outside of the water supply pipe, changing the detection position of the acoustic sensor 10. At the same time, in conjunction with the movement of the water supply pipe, the water supply pipe can be fully inspected. When the acoustic sensor 10 detects a hissing sound from a leak point, the controller 12 controls the buzzer 13 to work to remind the staff. This ensures the detection accuracy of the acoustic sensor 10, improves its detection effect, and has high performance.

[0027] The specific implementation process of this embodiment is as follows: First, place the device in place. During use, take the air pump 9 and air pipe 8 out of the storage box 1, then connect the air pump 9 to an external power source, and connect one end of the air pipe 8 to the air pump 9 and the other end to the water supply pipe passing through the rotating ring 6. Seal the other end of the water supply pipe with a corresponding sealing plug. Then, pressurize the inside of the water supply pipe with the air pump 9 and move the pressurized water supply pipe within the rotating ring 6. During the movement, the servo motor 5 drives the drive gear 15 to rotate. The drive gear 15 drives the rotating ring 6 to rotate through the tooth block 14, thereby driving the acoustic sensor 10 to rotate around the outside of the water supply pipe, changing the detection position of the acoustic sensor 10. At the same time, in conjunction with the movement of the water supply pipe, the water supply pipe can be fully detected. When the acoustic sensor 10 detects a hissing sound from a leak point, the controller 12 controls the buzzer 13 to work to remind the staff. This ensures the detection accuracy of the acoustic sensor 10, improves its detection effect, and has high performance.
