Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply pipeline leakage detection technology, specifically a water supply pipeline leakage detection device based on a hydrophone. Background Technology
[0002] Water supply pipeline leak detection refers to the use of a series of technologies and tools to detect and locate leaks in water supply pipelines. When a water supply pipeline leaks, water overflows under pressure, generating noise. This noise can propagate along the pipeline to both sides or along the medium to the ground. Leak detectors are often used in the process of water supply pipeline leak detection. Their working principle is to collect the sound waves or vibration signals generated when water leaks through a hydrophone, convert these signals into electrical signals, and send them to a signal processor for amplification, filtering, and other processing. Finally, the audio signal is sent to headphones, and at the same time, video signals such as graphics, waveforms, or numbers are also displayed on the screen, thereby helping to determine the specific location of the leak.
[0003] However, in the current process of using leak detectors to detect leaks in water supply pipelines, there is a lack of a structure for storing and adjusting the transmission line between the hydrophone and the leak detector. During use, the transmission line is prone to tangling due to its excessive length, and it is also prone to friction with the ground during personnel movement, thus affecting the overall service life and causing certain inconvenience to personnel. Utility Model Content

[0025] Example 1:
[0026] Please see Figures 1-5 As shown, this utility model provides a water supply pipeline leakage detection device based on a hydrophone, including a leakage detector main unit 1. A transmission line 8 is fixedly installed on the right end of the top of the leakage detector main unit 1, and an external hydrophone body 15 is fixedly installed on the right end of the transmission line 8. A winding disc 12 is fixedly connected to the upper end of the back of the leakage detector main unit 1. A receiving slot 17 is opened on the top of the winding disc 12, and a receiving cavity 23 is opened at the upper end of the winding disc 12. An L-shaped locking rod 16 is movably connected between the surface of the receiving cavity 23 and the surface of the receiving slot 17. A receiving hole 18 is opened in the middle of the back of the winding disc 12. A rotating rod 24 is movably connected to the surface of the receiving hole 18. The bottom of the L-shaped locking rod 16 is fixedly connected to the top of the rotating rod 24, and a coil spring 20 is fixedly connected between the front surface of the rotating rod 24 and the surface of the receiving hole 18.
[0027] In this technical solution, by setting the external hydrophone body 15, the vibration signal caused by the leakage sound can be collected during the water supply pipeline leakage detection process. At the same time, it can be transmitted to the leakage detector host 1 through the transmission line 8 and effectively processed. The signal is then presented on the display screen 3 as a graphic, waveform or digital signal to help relevant personnel determine the specific location of the leakage point. At the same time, the setting of the rotating rod 24, receiving hole 18, coil spring 20, L-shaped locking rod 16, receiving slot 17 and winding disc 12 makes it easy for personnel to stably store and adjust the length of the transmission line 8 during the water supply pipeline leakage detection process, avoiding the transmission line 8 from being too long and getting tangled or dragged and worn, which greatly facilitates the personnel's detection work.
[0028] Example 2:
[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-2As shown, the leak detector main unit 1 is disclosed with rubber corner protectors 2 fixedly connected around its four sides, rubber protrusions 6 fixedly connected to both sides of the rubber corner protectors 2, support blocks 11 fixedly connected around its four sides on the back of the leak detector main unit 1, handles fixedly connected to both sides of the leak detector main unit 1, a display screen 3 fixedly installed in the middle of the front surface of the leak detector main unit 1, a tempered protective film 4 affixed to the surface of the display screen 3, a control panel 5 fixedly installed at the lower end of the front surface of the leak detector main unit 1, and an earphone jack 7 fixedly connected to the top left end of the leak detector main unit 1, with a dust cover covering the top of the earphone jack 7.
[0030] In this technical solution, the rubber corner protectors 2 and rubber protrusions 6 are used to protect the leak detector main unit 1 from all sides, reducing damage caused by drops and collisions. The handle makes it easy for personnel to hold the leak detector main unit 1 during water supply pipeline leak detection. The tempered protective film 4 protects the front of the display screen 3. The dust cover protects the area around the headphone jack 7 from dust.
[0031] Example 3:
[0032] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 4 As shown, an annular guide groove 19 is provided at the middle of the receiving hole 18, an annular guide disk 21 is fixedly connected to the surface of the rotating rod 24, the surface of the annular guide disk 21 is movably connected to the surface of the annular guide groove 19, and movable balls 22 are movably connected between the four sides of the annular guide disk 21 and the four sides of the annular guide groove 19. A rubber sheath 9 is sleeved on the surface of the transmission line 8.
[0033] In this technical solution, the annular guide groove 19, the annular guide disk 21 and the movable ball 22 are used to limit and guide the rotating rod 24, so as to prevent the rotating rod 24 from loosening from the surface of the receiving hole 18 due to force. The rubber sleeve 9 is used to protect the transmission line 8 and reduce the damage to the outer sheath of the transmission line 8 during use.
[0034] Example 4:
[0035] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, the upper end of the external hydrophone body 15 is fitted with a rubber windproof tube 10, the inner cavity of the rubber windproof tube 10 is fixedly connected with a sound insulation cotton sleeve 13, and the lower end of the rubber windproof tube 10 is fixedly connected with a rubber pad 14.
[0036] In this technical solution, by setting up the rubber windproof tube 10, the sound insulation cotton sleeve 13 and the rubber soft pad 14, the surrounding area of the external hydrophone body 15 can be protected against wind and sound during the process of detecting water supply pipeline leakage, effectively reducing the impact of external sound on the detection work of the external hydrophone body 15.
[0037] The working principle of this utility model is as follows: When leakage detection of water supply pipelines is required, the external hydrophone body 15 is placed in the area to be detected. While collecting the vibration signal caused by the leakage sound, it can be transmitted to the leakage detector host 1 via the transmission line 8. After effective processing, the signal is displayed on the display screen 3 as a graphic, waveform, or digital signal to help relevant personnel determine the specific location of the leak. When the transmission line 8 needs to be retracted due to excessive length, the appropriate length of transmission line 8 is wound around the surface of the winding reel 12. By manipulating the rotating rod 24 to rotate, pressure is applied to the coil spring 20 inside the receiving hole 18, which in turn drives the L-shaped locking rod. After the L-shaped lever 16 detaches from the surface of the receiving slot 17, the operator can then secure the transmission line 8 inside the receiving slot 17. By stopping the rotation of the control lever 24 and pushing it with the reaction force of the coil spring 20, the L-shaped lever 16 can be inserted into the receiving slot 17, effectively limiting the upper part of the transmission line 8. This prevents the transmission line 8 from detaching from the receiving slot 17 and the surface of the winding reel 12 during subsequent use, ensuring the stability of the transmission line 8's storage. It also allows the operator to adjust the length of the transmission line 8 according to their needs, preventing it from becoming tangled or dragged and worn due to excessive length, greatly facilitating the operator's testing work.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
