Description

Technical Field

[0001] This utility model belongs to the field of sonar detection technology, specifically relating to a high-water-level sonar detection rod. Background Technology

[0002] In the structural inspection of drainage inspection wells and high-water-level pipelines, sonar technology is widely used due to its non-contact and underwater imaging capabilities. According to the "Technical Specification for Television and Sonar Inspection and Evaluation of Drainage Pipelines" (DB31 / T 444—2022), when the water level exceeds 50% of the pipeline diameter, sonar scanning becomes the main feasible technical means.

[0003] Currently, mainstream equipment mainly includes floating raft sonar systems, tethered remotely operated underwater vehicles (ROVs), and fixed array probes. These technical solutions have been deployed in several urban projects. However, the industry still faces the problem of technical route differentiation: on the one hand, there are complex systems represented by ROVs and multibeam sonar equipment. Although they are fully functional, they are costly, bulky, and complex to operate. On the other hand, there are low-cost tools represented by probe hooks and simple sonars. Although they are portable and easy to use, their accuracy and reliability are difficult to meet engineering requirements. This has led to a series of problems such as low detection efficiency, poor adaptability, and insufficient data integration, which seriously restricts the wide applicability and emergency response capability of drainage well detection under high water level conditions. Specifically, floating raft sonar equipment requires manual pulling of the cable on site. It is easy to get stuck when encountering bends or obstacles, interrupting the detection. Although ROV equipment has a high degree of automation, it relies on power cables and is bulky. Mobile deployment requires special vehicles, and the on-site response time is long, which is not conducive to the rapid location of sudden pipeline network failures. Therefore, this utility model proposes a high water level sonar detection rod. Utility Model Content

[0023] 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.

[0024] Example

[0025] Please see Figures 1 to 5 This is an embodiment of the present utility model, which provides the following technical solution: a high-water-level sonar detection rod, comprising...

[0026] The plug-in rod assembly is composed of multiple carbon fiber rods 11 connected together, with a quick-connect structure 12 between adjacent carbon fiber rods 11. The carbon fiber rods 11 are made of high-strength carbon fiber composite material, which is lightweight and tough, with an overall weight controlled within 8kg. It supports single-person shoulder carrying and rapid deployment, which is significantly better than ROV-type equipment that relies on dedicated transportation and multiple manual operations. It is more suitable for emergency operations and multi-point inspection scenarios. The length of the assembled carbon fiber rods 11 ranges from 3 to 5 meters, which is suitable for inspection well environments of different depths. In order to improve the accuracy of logging depth data and the convenience of operation, the surface of the rod is provided with wear-resistant range scale markings (unit: cm) to facilitate quick reading of the descent depth on site and achieve precise control of the detection position. The carbon fiber rods 11 have a pre-set waterproof cable groove inside, which integrates a plug-in connection cable that can connect the array sonar detection base 2 and the processing and communication top mount 3, avoiding the risk of exposed cable entanglement.

[0027] The array-type sonar detection base 2 is detachably mounted at the bottom of the plug-in rod assembly. The array-type sonar detection base 2 has a built-in multi-channel sonar probe to achieve 360° circular scanning. The probe adopts a dual-frequency transmission structure: in low-density sedimentation scenarios, it automatically switches to a high-frequency 1.2MHz mode to achieve high-resolution imaging (accuracy up to 2mm) of pipe wall details (such as cracks and corrosion); in high-density sedimentation areas, it switches to a low-frequency 500kHz mode to improve penetration and recognition capabilities. It also has real-time signal acquisition capabilities and integrates a high-performance A / D conversion chip to ensure the quality of the original signal.

[0028] The processing and communication top mount 3 is detachably installed on the top of the plug-in pole assembly. A bubble level 31 is installed on the top surface of the processing and communication top mount 3. After installation, it can be connected to the array-type sonar detection base 2 through the plug-in connecting wire in the carbon fiber pole 11. The processing and communication top mount 3 has a built-in embedded microprocessor unit (MCU) and edge computing chip to process sonar signals in real time and generate point cloud data. It corrects the signal distortion caused by suspended objects or bubbles through the sound wave compensation algorithm, so that the imaging clarity is improved by about 70% compared with traditional sonar, significantly optimizing the identification accuracy in turbid water. It is also equipped with a 5G communication module to upload the filtered data to the remote GIS platform and municipal database at high speed. It also integrates a high-precision gyroscope and positioning sensor to achieve accurate binding of defect points and urban coordinates (error ≤ ±10cm), which greatly improves maintenance and scheduling efficiency. In addition, it also integrates an electronic tilt sensor, which can work with the bubble level 31 to calibrate the vertical attitude of the pole in real time to ensure the authenticity of the data.

[0029] Addressing the technical challenges of sonar detection in high-water-level well conditions (water depth ≤ 20 meters) within municipal pipe networks, the array-type sonar detection base 2 employs a watertight joint and a dynamic sealing structure with double O-rings to achieve redundant sealing with primary and backup features. The overall protection level reaches IP68. Specifically, this includes: firstly, a dynamic compensation design with double O-rings at the connection surface between the array-type sonar detection base 2 and the lower carbon fiber rod 11. The double O-rings are made of hydrogenated nitrile rubber material resistant to sewage corrosion, allowing the backup ring to respond instantly in case of primary seal failure; secondly, in the array-type... The sonar detection base 2 is equipped with a diaphragm-type pressure balancing valve (which is existing technology; for details, please refer to the existing patent with publication number CN204083360U, which will not be elaborated here). It uses a highly sensitive silicone diaphragm microporous structure to achieve synchronization of internal and external pressure within the cavity in less than 0.1 seconds, effectively offsetting the dynamic pressure difference caused by sudden rises in water pressure during heavy rain or water hammer from water pumps. Thirdly, the outer shell of the array-type sonar detection base 2 is made of thickened aerospace aluminum alloy and has an anti-deformation design, which can withstand 20 meters of water pressure and ensure long-term sealing stability.

[0030] In this embodiment, preferably, the quick-connect structure 12 includes a connecting base 121 fixed to the bottom surface of the carbon fiber rod 11 and a connecting top seat 122 fixed to the top surface of the carbon fiber rod 11. The bottom surface of the connecting base 121 is provided with an integral connecting sleeve 124, and the top of the connecting top seat 122 is provided with a connecting slot 125 for the connecting sleeve 124 to be inserted. The quick-connect structure 12 also includes an elastic locking structure 123, and the elastic locking structure 123 is disposed between the connecting base 121 and the connecting top seat 122.

[0031] In this embodiment, preferably, the elastic locking structure 123 includes an elastic locking seat 1231 movably mounted on the outer surface of the connecting base 121, a triangular locking block 1232 fixed to the inner side of the bottom end of the elastic locking seat 1231, and a connecting slot 1233 opened on the outer surface of the connecting top seat 122 and corresponding to the triangular locking block 1232. The triangular locking block 1232 is inserted into the connecting slot 1233, which can realize the quick locking connection between the connecting base 121 and the connecting top seat 122, and facilitate the quick connection of multiple carbon fiber rods 11 together.

[0032] In this embodiment, preferably, the elastic locking structure 123 further includes an inner sliding groove 1234 formed inside the connecting base 121, an inner sliding seat 1236 slidably disposed in the inner sliding groove 1234, and a connecting rod 1237 fixed to the side of the inner sliding seat 1236. The end of the connecting rod 1237 extends through to the outside of the connecting base 121 and is fixed to the elastic locking seat 1231. A spring 1235 is also installed on the inner side of the inner sliding groove 1234 relative to the inner sliding seat 1236, which abuts against the inner sliding seat 1236. Under the abutting action of the spring 1235, the elastic locking structure 1233 is engaged in daily use. During use, the elastic retainer 1231 is tightly pressed against the outer surface of the connecting top seat 122, causing the triangular retainer 1232 to be stably locked in the connecting slot 1233, ensuring the connection stability between the carbon fiber rods 11. In actual connection, simply align the connecting base 121 at the bottom of the upper carbon fiber rod 11 with the connecting top seat 122 at the top of the lower carbon fiber rod 11, causing the connecting sleeve 124 to be inserted into the connecting slot 125. This causes the triangular retainer 1232 to shift laterally due to the pressure from the outer wall of the connecting top seat 122, resulting in the elastic retainer 1231 shifting laterally to connect the... Rod 1237 and inner slide 1236 move laterally together, compressing spring 1235 until connecting sleeve 124 is fully inserted into connecting slot 125, and connecting base 121 and connecting top seat 122 are in contact. At this time, triangular block 1232 is aligned with connecting slot 1233. Then, under the push of spring 1235, inner slide 1236, connecting rod 1237 and elastic seat 1231 spring back to their original positions, finally causing triangular block 1232 to engage in connecting slot 1233, thus quickly completing the connection between the upper and lower carbon fiber rods 11. To facilitate the assembly of the plug-in rod assembly, after the plug-in rod assembly is completed, the processing and communication top mount 3 and the array sonar detection base 2 are respectively installed at the upper and lower ends of the plug-in rod assembly and connected through the plug-in connecting wire in the carbon fiber rod 11. This completes the assembly of the high-water-level sonar detection rod. Finally, the processing and communication top mount 3 is connected to an external detection terminal platform through a standard industrial interface. Then, the array sonar detection base 2 is placed in a drainage inspection well or high-water-level pipeline to perform sonar detection and complete the data acquisition, processing, and transmission tasks.

[0033] In this embodiment, preferably, the inner slide 1236 has a mounting groove on its side corresponding to the spring 1235. One end of the spring 1235 is embedded in the mounting groove, so that the spring 1235 is not easy to deviate or run off course during daily use, thus achieving a stable pressing effect on the inner slide 1236.

[0034] In this embodiment, preferably, an arc-shaped pinch block is fixed on the outer surface of the elastic card holder 1231, which facilitates the subsequent disassembly of the plug-in rod assembly. When the operator pinches the pinch block, he pulls the elastic card holder 1231 to the side, causing the triangular card block 1232 to move out of the connecting card slot 1233, so that the upper and lower carbon fiber rods 11 can be directly disassembled.

[0035] In this embodiment, preferably, the quick-connect structure 12 further includes a sealing structure 126 disposed between the connecting base 121 and the connecting top seat 122. The sealing structure 126 includes an annular rubber seat 1261 embedded in the bottom surface of the connecting base 121, two annular sealing protrusions 1262 disposed on the bottom surface of the annular rubber seat 1261, and two annular sealing grooves 1263 formed on the top surface of the connecting top seat 122. The annular sealing protrusions 1262 are squeezed into the annular sealing grooves 1263, so that after the upper and lower carbon fiber rods 11 are assembled, the annular sealing protrusions 1262 will be squeezed into the annular sealing grooves 1263 and undergo elastic deformation to form an effective seal and ensure the sealing performance after connection. The annular rubber seat 1261 and the annular sealing protrusions 1262 are both made of rubber material and will undergo elastic deformation when squeezed.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
