Abstract
Description
Technical Field
[0001] This application relates to the field of underground water supply pipeline tracing and detection technology, and in particular to a sound source generating device for detecting the location of underground water supply pipelines. Background Technology
[0002] Acoustic detection technology utilizes the properties of sound wave propagation to detect underground pipelines. Its basic principle involves using instruments to generate sound waves, which propagate through underground pipes and backfill layers, and are then received and analyzed by a receiver. Applications of acoustic detection technology in pipeline detection mainly include acoustic waveguides, sound wave transmission, and the reflection, diffraction, refraction, interference, superposition, and absorption of sound waves.
[0003] In the field of underground water supply pipeline tracing and detection, electromagnetic technology is mainly used for tracing and detection. However, this technology is not effective for non-metallic pipelines. Currently, the commonly used acoustic detection and tracing methods cannot be used for pipeline tracing and detection under water and pressure conditions. It is necessary to drain the water medium in the pipeline and use the gas in the pipeline to propagate sound waves for pipeline detection. This is complicated to operate and has low reliability for water supply networks. Utility Model Content
[0004] To address the shortcomings of traditional detection methods, such as insufficient accuracy in detecting non-metallic pipelines or low efficiency due to the inability to detect them under water pressure in water supply networks, this application provides a sound source generating device for detecting the location of underground water supply pipelines.
[0005] The sound source generating device for detecting the location of underground water supply pipelines provided in this application adopts the following technical solution:
[0006] A sound source generating device for detecting the location of underground water supply pipelines includes a sound-collecting box, a sealing cover, a control mechanism, and a sound source generating device. The sound-collecting box is detachably installed on the water supply pipeline, and the sealing cover and the sound-collecting box are locked together by a locking device. The control mechanism is installed on the sound-collecting box and the sealing cover respectively, and is used to control the liquid and gas inside the sound-collecting box. The sound source generating device is installed on the sealing cover located inside the sound-collecting box.
[0007] By adopting the above technical solution, this sound source generating device can effectively detect the location of water supply pipelines under pressurized conditions. The conical design of the sound-collecting box reduces sound energy loss. The sound-collecting box has a built-in pipe interface for installation on the water supply pipeline, facilitating installation and maintenance. The sealing cover and the sound-collecting box are locked together with locking components, ensuring the equipment's sealing and stability. Control mechanisms are installed on the sound-collecting box and the sealing cover respectively, used to control the liquid and gas inside the sound-collecting box, thereby ensuring the normal operation of the equipment in a pressurized environment. The sound source generating device is installed on the sealing cover inside the sound-collecting box, emitting a sound source that propagates through the water medium into the water supply pipeline. By picking up the sound wave signals propagating in the water supply pipeline and other media on the ground, the location of the water supply pipeline can be accurately determined.
[0008] Optionally, the sound source generating device includes a loudspeaker and a channel amplifier. The loudspeaker is mounted on a sealing cover located inside the sound box, and the channel amplifier and the loudspeaker are connected by an electrical signal.
[0009] By adopting the above technical solutions, the sound source generating device can accurately generate and transmit sound signals, improving the accuracy and reliability of detecting the location of underground water supply pipelines. The loudspeaker directly applies the sound signal to the inside of the water supply pipeline, guiding the wave through the pipeline. This guides limited energy through a smaller cross-section, reducing energy loss and increasing the signal strength at the detection location. By adjusting the signal frequency, other noise interference can be effectively reduced, enhancing the reliability of the detection. The channel power amplifier can effectively amplify and adjust the sound signal, ensuring stable detection results under different environmental conditions.
[0010] Optionally, the control mechanism includes an exhaust valve and a control valve. The control valve is installed at the end of the sound box away from the sealing cover for connecting the equipment to the water supply pipe, and the exhaust valve is installed on the sealing cover for controlling the gas inside the sound box.
[0011] By adopting the above technical solution, the control mechanism can effectively regulate the gas and liquid inside the sound box, ensuring that the sound source generating device operates in a stable working environment with water and pressure. The exhaust valve can accurately discharge the gas inside the sound box to prevent air bubbles from interfering with the propagation of sound waves. The control valve is located at the end of the sound box away from the sealing cover, which allows the operator to easily regulate the liquid, so that the water medium in the pipeline fills the sound box and the equipment is in the same working condition as the water supply pipeline.
[0012] Optionally, a sealing ring is also installed on the speaker enclosure, and the sealing ring and the sealing cover abut against one end of the speaker enclosure.
[0013] By adopting the above technical solution, the sealing ring can effectively prevent gas from leaking from the gap between the speaker box and the sealing cover, improving the sealing performance and reliability of the equipment. The tight contact between the sealing ring and the sealing cover enhances the overall structural stability and ensures that it will not loosen due to changes in external pressure during use.
[0014] Optionally, the speaker box has several mounting holes, the sealing cover has positioning holes that match the mounting holes, and the locking component includes a locking bolt and a locking nut, with the locking bolt passing through the mounting hole, the positioning hole and the locking nut in sequence for threaded engagement.
[0015] By adopting the above technical solution, the mounting holes and positioning holes enable the sealing cover to be accurately aligned with the sound box, ensuring installation accuracy; the threaded connection achieves reliable fixation between the sealing cover and the sound box, improving the overall stability and sealing of the equipment.
[0016] Optionally, the speaker has multiple mounting holes, and a fastening bolt is installed in each mounting hole. The fastening bolt passes through the speaker and the sealing cover and is threaded together.
[0017] By adopting the above technical solution, the fastening bolts pass through the assembly hole to firmly fix the speaker on the sealing cover, which enhances the overall stability and reliability of the equipment and prevents the speaker from loosening or falling off due to vibration or impact during use, thereby ensuring the normal operation of the sound source generating device.
[0018] Optionally, the cross-section of the sound box is tapered.
[0019] By adopting the above technical solution, the cross-section of the sound box is conical. The conical structure helps to optimize the sound propagation path, reduce the loss of sound energy, and improve the working efficiency of the sound source generating device.
[0020] Optionally, the diameter of the sealing cover is equal to the diameter of the speaker box.
[0021] By adopting the above technical solution, the diameter of the sealing cover is equal to the diameter of the sound box, ensuring a tight fit between the sealing cover and the sound box, effectively preventing gas leakage, improving the sealing performance and reliability of the equipment, and making the sealing cover easy to install and disassemble, and convenient for maintenance and repair.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The speaker box and sealing cover are locked together with locking devices to ensure the reliability and sealing of the equipment, avoid tracer detection errors caused by leakage, and improve the tracer detection accuracy and reliability;
[0024] 2. The control mechanism includes an exhaust valve and a control valve, which can control the liquid and gas inside the sound box to ensure that the sound source generating device operates in the best working condition, thereby improving the stability and accuracy of the sound wave signal;
[0025] 3. The sound source generating device includes a loudspeaker and a channel amplifier, which are connected by electrical signals to achieve efficient and stable sound wave signal transmission, thereby improving the detection efficiency and accuracy of underground water supply pipelines.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a sound source generating device for detecting the location of underground water supply pipelines.
[0034] Reference Figure 1The device includes a sound-collecting box 1, a sealing cover 2, a control mechanism 3, and a sound source generating device 4. It is designed for underwater operation, utilizing acoustic wave guidance and penetration methods to detect the location of underground water supply pipelines. The sound-collecting box 1, with its own pipe interface, is detachably installed on the water supply pipeline. The sealing cover 2 and the sound-collecting box 1 are locked together by a locking device 5. The diameter of the sealing cover 2 is equal to the diameter of the sound-collecting box 1, ensuring a tight fit and preventing leakage. The control mechanism 3 is installed on both the sound-collecting box 1 and the sealing cover 2, controlling the liquid and gas inside the sound-collecting box 1. The sound source generating device 4 is installed on the sealing cover 2 inside the sound-collecting box 1, achieving the effect of accurately detecting the location of underground water supply pipelines by emitting sound waves and receiving reflected signals. After the water supply pipeline is connected, the device operates in a pressurized, water-filled environment. Sound waves enter the water supply pipeline through the water medium and propagate through the water. During operation, the cavity is filled with water, and the collected sound source gradually narrows in diameter and is concentratedly transmitted into the water supply pipeline.
[0035] See Figure 1 and Figure 2 As shown, the sound source generating device 4 includes a loudspeaker 41 and a channel amplifier 42. The loudspeaker 41 is connected to the channel amplifier 42 via an electrical signal. The channel amplifier 42 is an existing sound source device that plays single-frequency sound waves. It can effectively amplify and adjust the sound signal to ensure stable detection results under different environmental conditions. The loudspeaker 41 has multiple mounting holes, and each mounting hole is fitted with a fastening bolt 7. The fastening bolt 7 passes through the loudspeaker 41 and the sealing cover 2, which are threaded together to ensure that the loudspeaker 41 is firmly fixed and not easy to fall off. The channel amplifier 42 is responsible for amplifying the electrical signal so that the loudspeaker 41 can emit a sufficiently strong sound wave that can penetrate the soil layer to detect underground pipelines. The sound signal is directly applied to the inside of the water supply pipeline and guided through the pipeline. The limited energy is guided through a smaller cross-section, reducing energy loss and increasing the signal strength of the tracer detection position. By adjusting the frequency of the signal, other noise interference can be effectively reduced, enhancing the reliability of the tracer detection.
[0036] See Figure 4 As shown, the control mechanism 3 includes an exhaust valve 31 and a control valve 32. The control valve 32 is installed at the end of the sound box 1 away from the sealing cover 2 and is used to control the liquid flow inside the sound box 1 to ensure the pressure balance inside the equipment. The exhaust valve 31 is installed on the sealing cover 2 and is used to discharge the gas inside the sound box 1 to prevent air bubbles from interfering with the propagation of sound waves. When the water in the pipe fills the cavity, the exhaust valve 31 will discharge the gas and fill the cavity with water medium.
[0037] See 2 and Figure 3As shown, the speaker enclosure 1 has several mounting holes 8, and the sealing cover 2 has positioning holes 9 that match the mounting holes 8. The locking component 5 includes a locking bolt 51 and a locking nut 52. The locking bolt 51 passes through the mounting hole 8, the positioning hole 9 and the locking nut 52 in sequence for threaded engagement, ensuring a tight connection between the sealing cover 2 and the speaker enclosure 1.
[0038] See Figure 3 As shown, the cross-section of the sound box 1 is conical. The conical shell can better adapt to water supply pipes of different diameters, reduce friction during installation, and facilitate quick installation and disassembly. The conical structure helps to optimize the sound propagation path and reduce the loss of sound energy. The sound box 1 is equipped with a sealing ring 6 inside. The sealing ring 6 and the sealing cover 2 abut against each other at the end near the sound box 1. The sealing ring 6 is made of rubber material, which has good elasticity and sealing performance, preventing water from entering the sound box 1 and affecting the normal operation of the equipment.
[0039] The implementation principle of a sound source generating device for detecting the location of underground water supply pipelines according to an embodiment of this application is as follows: a sound box 1 is detachably installed on the water supply pipeline, and a sealing cover 2 and a sound box 1 are tightly connected by a locking member 5 to form a closed space. The control mechanism 3 includes an exhaust valve 31 and a control valve 32, which are used to regulate the liquid and gas inside the sound box 1 to maintain the pressure balance inside the device. The sound source generating device 4 includes a loudspeaker 41 and a channel power amplifier 42. The loudspeaker 41 is installed on the sealing cover 2 and is connected to the channel power amplifier 42 through an electrical signal to emit sound waves. The sound wave signals are picked up by a listening device on the ground to achieve accurate detection of the location of the underground water supply pipeline. The overall device structure is easy to operate and is suitable for underground pipeline detection under various complex geological conditions.
