Description

Technical Field

[0001] The utility model relates to the technical field of tap water detection, in particular to a tap water pressure pipeline leakage detection device. Background Art

[0002] The method of using the leak detector is that when the tap water rushes out from the broken hole in the water pipe after a water pipe leaks, the sound vibration generated by the friction with the pipe wall and other additional vibrations caused are transmitted to the ground above the pipe. The instrument is used to detect on the road surface to find the leak. When the fluid in the pipe overflows under pressure, the noise generated can be transmitted along the pipe, or the buried layer medium is transmitted to the ground. The leak detector can determine the location of the leak along the pipeline or above the road surface. The traditional leak detector collects the vibration signal caused by the leakage through a vibration pickup, and converts the vibration signal into an electrical signal and transmits it to the signal processor for amplification, filtering and other processing. Finally, the audio signal is sent to the earphone, and the video signal such as graphics, waveforms or numbers is displayed on the display screen to help determine the leak.

[0003] After searching, a Chinese utility model proposes a water pipe leakage detector (Announcement No.: CN 217784873U). By pulling out the arc fixing rod downwards, when it reaches above the fixing rod baffle, the fixing rod base is snapped into the grooves on both sides of the arc fixing rod base to fix it. The arc fixing rod is pulled outward by the fixing rod spring, and water pipes of different sizes can be fixed and tested. This solves the problem that when a suspended or external water pipe needs to be tested, the traditional vibration pickup of the arc water pipe cannot be fixed and needs to be manually straightened, which is very time-consuming and labor-intensive. This achieves the effect of fixing water pipes of different sizes at different positions, saving time and effort. However, it still has defects. When inspecting along the waterline pipeline, the staff needs to repeatedly hold the vibration pickup for fixed detection, which not only has low detection efficiency but also has high work intensity.

[0021] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the four corners of the lower surface of the vehicle plate 1 are fixedly connected with support columns 2, and the lower surface of the support columns 2 is installed with universal wheels 3. The vehicle plate 1 is installed with a leakage detector body 5 (the technical content of the leakage detector body 5 in this embodiment is already known to technicians in this field, and there are many leakage detector bodies 5 on the existing market, such as JT-5000 of Yangzhou Jietong Water Supply Technology Equipment Co., Ltd.), a vibration pickup 10 is installed in the interface of the leakage detector body 5, and an earphone 9 is installed in another interface of the leakage detector body 5. The lower surface of the vehicle plate 1 is connected with a vertical fixing mechanism, and the vertical fixing mechanism The vehicle plate 1 comprises an electric push rod 11, a first fixing block 12, a first U-shaped frame plate 13, a first trapezoidal screw 14 and a first arc-shaped clamping block 15. The electric push rod 11 is installed on the lower surface of the vehicle plate 1. The output end of the electric push rod 11 is fixedly connected to the first fixing block 12. One side of the first fixing block 12 is provided with a first arc-shaped groove matching the vibration pickup 10. One side of the first fixing block 12 is also fixedly connected to the first U-shaped frame plate 13. The first trapezoidal screw 14 is threadedly connected to the first U-shaped frame plate 13. One end of the first trapezoidal screw 14 is rotatably connected to the first arc-shaped clamping block 15 matching the vibration pickup 10. The arc-shaped clamping block 15 is slidably connected to the inner side surface of the first U-shaped frame plate 13. The vehicle plate 1 is connected to a horizontal fixing mechanism, which includes a connecting rod 6, an adjusting block 7, a trapezoidal screw 17, a nut block 18, a second fixing block 19, a second U-shaped frame plate 20, a second trapezoidal screw 21 and a second arc-shaped clamping block 22. An adjusting block 7 is provided on one side of the vehicle plate 1. The rear end surface of the adjusting block 7 is fixedly connected to the vehicle plate 1 through two symmetrically arranged connecting rods 6. A sliding groove is provided on the front end surface of the adjusting block 7. The inner lower surface of the sliding groove is rotatably connected to the trapezoidal screw 17. The upper end of the trapezoidal screw 17 passes through the adjusting block 7. A nut block 18 matching the slide groove is threadedly sleeved on the trapezoidal lead screw 17, one end of the nut block 18 extends outside the slide groove and is fixedly connected to a second fixing block 19, a second arc groove matching the vibration pickup 10 is opened on the upper surface of the second fixing block 19, and a second U-shaped frame plate 20 is also fixedly connected to the upper surface of the second fixing block 19, a second trapezoidal screw 21 is threadedly connected to the second U-shaped frame plate 20, and the lower end of the second trapezoidal screw 21 is rotatably connected to a second arc-shaped clamping block 22 matching the vibration pickup 10, and the second arc-shaped clamping block 22 is slidably connected to the inner side surface of the second U-shaped frame plate 20.

[0022] It should be noted that when it is necessary to perform leakage detection on the buried water pipeline, the tail of the vibration pickup 10 is placed in the first arc groove on the first fixing block 12, and then the first trapezoidal screw 14 is rotated. Since the first arc clamping block 15 is rotationally connected to the first trapezoidal screw 14, and the first arc clamping block 15 is slidably connected to the inner side of the first U-shaped frame plate 13, the rotation of the first trapezoidal screw 14 drives the horizontal movement of the first arc clamping block 15, and the tail of the vibration pickup 10 is clamped and fixed in the first arc groove on the first fixing block 12 by the first arc clamping block 15, and then Then, the vehicle plate 1 is moved by the universal wheel 3 to move the device on the waterline pipeline. During the detection, the electric push rod 11 drives the first fixed block 12 to make the end of the vibration pickup 10 contact the ground to detect the noise signal from the leakage point below the ground. After the vibration pickup 10 processes the signal, it finally sends the audio signal to the earphone 9, and displays the video signal such as graphics, waveforms or numbers on the display screen of the leakage detector body 5 to determine the leakage point. After the detection is completed, the electric push rod 11 is retracted to make the vibration pickup 10 away from the ground, and then the vehicle body is moved along the waterline pipeline to perform leakage detection at the next location;

[0023] When it is necessary to perform leakage detection on the waterline pipeline suspended horizontally in the air, the tail of the vibration pickup 10 is placed in the second arc groove on the second fixed block 19, and then the second trapezoidal screw 21 is rotated. Since the second arc clamping block 22 is rotationally connected to the second trapezoidal screw 21, and the second arc clamping block 22 is slidably connected to the inner side of the second U-shaped frame plate 20, the feeding of the second trapezoidal screw 21 can drive the second arc clamping block 22 to move vertically downward, clamping and fixing the tail of the vibration pickup 10 in the second arc groove on the second fixed block 19, and then, the nut block 18 is driven to move vertically in the slide groove by rotating the trapezoidal screw 17, and the movement of the nut block 18 drives the second fixed block 1 9 moves, so that the clamped vibration pickup 10 moves accordingly. The height of the vibration pickup 10 is adjusted according to the height of the waterline pipeline. After the adjustment is completed, the vehicle plate 1 is moved by the universal wheel 3 to move the device along the waterline pipeline. During the detection, the vehicle body is moved so that the vibration pickup 10 with the same height as the waterline pipeline touches the pipeline to detect the noise signal from the leakage point. The vibration pickup 10 processes the signal and finally sends the audio signal to the earphone 9. The video signal such as graphics, waveforms or numbers is displayed on the display screen of the leakage detector body 5 to determine the leakage point. After the detection is completed, the vehicle body is moved to keep the vibration pickup 10 away from the pipeline, and then the vehicle body is moved along the waterline pipeline to perform leakage detection at the next location.

[0024] To summarize, the present device, through the vertical fixing mechanism and the horizontal fixing mechanism, when detecting the leakage point of the waterline pipeline, whether it is for the waterline pipeline buried underground or for the waterline pipeline suspended horizontally in the air, the staff only needs to move along the waterline pipeline through the universal wheel 3 to conveniently and quickly perform leakage detection, without the need for the staff to repeatedly hold the vibration pickup 10 for detection, which not only improves the detection efficiency but also reduces the work intensity.
