[0016] 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.

[0017] Please see Figures 1-7 The device for detecting pipeline leak noise offers two technical solutions: The first implementation method includes a collector body 1 and a hydrophone sensor probe 2. The collector body 1 and the hydrophone sensor probe 2 are connected by a waterproof cable 3, and the waterproof cable 3 is provided with a storage mechanism. The storage mechanism includes a storage box 41. An outer rotating rod 42 is rotatably connected between the front and back of the inner wall of the storage box 41. The outer rotating rod 42 is hollow. A winding drum 43 is fixedly connected to the surface of the outer rotating rod 42 inside the storage box 41. The waterproof cable 3 is wound around the outside of the winding drum 43. An inner rotating rod 44 is movably connected inside the outer rotating rod 42. Two limiting components 5 are provided on the inner rotating rod 44. The limiting components 5 are used to limit and retract the position of the waterproof cable 3 after it is released. Two symmetrically arranged grooves 45 are opened at one end of the outer rotating rod 42. Two driving rods 46 corresponding to the positions of the grooves 45 are fixedly connected to the surface of the inner rotating rod 44. The two limiting components 5 are respectively provided at one end of the two driving rods 46.

[0018] The limiting assembly 5 includes a fixed rod 51 fixed to the driving rod 46. A limiting claw 52 is rotatably connected to the surface of the fixed rod 51. Arc-shaped grooves 54 are provided on both sides of the limiting claw 52. A stop block 55 is fixedly connected to the surface of the fixed rod 51, and the stop block 55 is located inside the arc-shaped groove 54. The arc-shaped groove 54 and the stop block 55 cooperate to limit the rotation angle of the limiting claw 52. Torsion springs 53 are sleeved on both sides of the fixed rod 51 located on the driving rod 46. One end of the torsion spring 53 is fixedly connected to one side of the driving rod 46. The other end of the torsion spring 53 is fixedly connected to the limiting claw 52. The back of the storage box 41 is fixedly connected to the first protective box 56. Multiple limiting blocks 57 are evenly arranged on the inner surface of the first protective box 56. The limiting blocks 57 cooperate with the limiting claw 52. The front of the fixing rod 51 is fixedly connected to the second protective box 58. The inside of the second protective box 58 is provided with a spring 59. One end of the spring 59 is fixedly connected to the surface of the outer rotating rod 42, and the other end of the spring 59 is fixedly connected to the inner surface of the spring 59.

[0019] The waterproof cable 3 between the main body 1 of the data collector and the hydrophone sensor probe 2 is stored by the storage component 4. After the device is used, the waterproof cable 3 is retracted by the winding drum 43, thereby avoiding the problem of the waterproof cable 3 being scattered and tangled. Furthermore, the position of the released waterproof cable 3 is limited by the cooperation of the limiting component 5, which improves the practicality of the device during use.

[0020] The second implementation differs from the first implementation in that: the main body 1 of the collector includes a protective shell 11, a battery bracket 12 is fixedly connected to the bottom of the inner wall of the protective shell 11, a lithium battery 13 is installed on the battery bracket 12, a collection and transmission circuit 14 is provided inside the protective shell 11, and two antennas 15 are provided on the top of the protective shell 11. The collection and transmission circuit 14 is connected to the antennas 15. The hydrophone sensor probe 2 includes a potted piezoelectric ceramic sensor 21 and a front-end low-noise amplification module 22. The potted piezoelectric ceramic sensor 21 and the front-end low-noise amplification module 22 are electrically connected, and the front-end low-noise amplification module 22 is connected to the collection and transmission circuit 14 through a waterproof cable 3.

[0021] When in use, the device collects information through a potted piezoelectric ceramic sensor 21 and transmits the collected data wirelessly through the main body 1 of the collector, thereby enabling better analysis of pipeline leakage noise. In addition, an internal lithium battery 13 is installed to improve the device's battery life.

[0022] In use, information is collected through the potted piezoelectric ceramic sensor 21, and the collected data is amplified by the front-end low-noise amplification module 22 and transmitted to the main body 1 of the collector. Finally, the collected data is transmitted through the acquisition and remote transmission circuit 14 and the antenna 15. When collecting information through the hydrophone sensor probe 2, the inner rotating rod 44 is rotated. The rotation of the inner rotating rod 44, through the cooperation of the driving rod 46 and the groove 45, causes the outer rotating rod 42 to rotate. The rotation of the outer rotating rod 42 releases the waterproof cable 3 wound on the surface of the take-up drum 43, thereby increasing the length of the waterproof cable 3. During the release, the waterproof cable 3... Both ends are released simultaneously, making it easy for the hydrophone sensor probe 2 to be placed in the water. When the inner rotating rod 44 rotates, it drives the limiting claw 52 to rotate together. The limiting claw 52 cooperates with the limiting block 57. The limiting claw 52 rotates and passes the position of the limiting block 57. After the rotation stops, the limiting block 57 blocks and limits the limiting claw 52, ​​thereby limiting the position of the winding drum 43. When it is necessary to rewind the cable, the inner rotating rod 44 is pushed to move, so that the driving rod 46 comes out of the groove 45. At this time, the outer rotating rod 42 is rotated and reset by the action of the spring 59, thereby allowing the waterproof cable 3 to be wound and retracted into the storage assembly 4.
