Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline detection technology, and in particular to a sonar pipeline detection device. Background Technology
[0002] Sonar pipeline detection devices are specialized equipment that uses sonar (sound wave detection) technology to detect the internal structure, defects, or blockages of pipelines, and are especially suitable for pipeline inspection in underwater, underground, or complex environments.
[0003] A Chinese patent for a conveniently installed pipeline sonar detector (publication number CN219799786U, application date 2023-05-04) uses an electric push rod to drive the first and second connecting rods, thereby raising the support plate, sensor, probe head, and searchlight for detection. After detection, the components descend into the support box for protection, effectively solving the problem of the probe head being exposed and damaged. The support box is placed inside the drive vehicle and can be lifted to remove it, making it convenient to operate, install, and disassemble. However, the added lifting mechanism makes the internal structure of the drive vehicle more complex and occupies more internal space. When the sensor, probe head, and searchlight are raised for detection, the support box is completely open, which may lead to water accumulation in the pipeline, making the operating environment more demanding. Furthermore, the work box requires disconnecting the connecting wires before placing the drive vehicle in for retrieval, further improving its convenience.
[0004] In summary, a sonar pipeline detection device is needed to address the shortcomings of existing technologies. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a sonar pipeline detection device, which aims to solve the above problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sonar pipeline detection device, comprising a working box, a detection trolley, and a sonar sensor. The working box is used for storing the detection trolley and facilitating its entry and exit. The detection trolley includes a first cavity and a second cavity, which are independent of each other. The second cavity is located at the front end of the detection trolley. The sonar sensor is installed in the second cavity. The detection trolley has a cover plate assembly on the side near the second cavity. The cover plate assembly is used for flipping and adjusting to protect the sonar sensor inside the second cavity. The flexible adjustment of the cover plate assembly enhances the device's protective capabilities in deep water and complex pipelines. The integrated design of the working box and the automatic ramp door simplify the operation process and improve operational convenience. The modular cavity layout and detachable structure optimize maintenance efficiency, reduce the failure rate, extend service life, and significantly improve the adaptability and reliability of the detection device.
[0007] In one embodiment, the cover plate assembly includes a cover plate body, a connector, and an electric telescopic rod. The cover plate body is used to seal and shield the second cavity. The connector is fixedly mounted on the cover plate body. The electric telescopic rod is mounted on the outer top wall of the probe trolley near the first cavity. The piston end of the electric telescopic rod is hinged to the connector.
[0008] In one embodiment, the cover plate body has an L-shaped structure and is located on the side close to the second cavity.
[0009] In one embodiment, the work box includes a storage compartment, a base, a limiting component, and a door panel assembly. The storage compartment is used to store the probe trolley. The base is located at the bottom of the storage compartment. The limiting component is used to limit and fix the probe trolley stored inside the storage compartment. One side of the work box has an inlet and outlet for connecting to the storage compartment. The door panel assembly is installed on the outside of the inlet and outlet. The door panel assembly is used to seal the inlet and outlet of the work box when the probe trolley is stored. When the probe trolley drives out, it flips open the inlet and outlet and serves as a bottom inclined floor.
[0010] In one embodiment, the bottom of the platform has a cavity in the middle, and the upper surface of the platform has openings at the four corners of the top of the cavity.
[0011] In one embodiment, the limiting component includes a cylinder, a bracket, and a baffle. The cylinder and the bracket are both disposed in a cavity. The piston end of the cylinder is connected to the bracket. The baffle is installed at the top four corners of the bracket and is located directly below the opening.
[0012] In one embodiment, the door panel assembly includes a panel and a limiting block. The bottom two sides of the panel are hinged to the work box. The limiting block is installed on the work box and located directly above the entrance and exit, and the limiting block is used to limit and fix the panel in a vertical state.
[0013] The beneficial effects of this utility model are:
[0014] 1. In this utility model, by setting up an L-shaped cover plate assembly and an electric telescopic rod, dynamic sealing protection of the sonar sensor is achieved. In the non-detection state, the cover plate completely covers the second cavity, effectively preventing water accumulation in the pipeline, foreign object intrusion, or mechanical collision from damaging the sensor. During detection, the electric telescopic rod precisely controls the flip angle of the cover plate, which can expose the sensor for detection while avoiding the carrier box from being completely open, significantly improving the adaptability of the equipment in deep water or complex pipeline environments.
[0015] 2. In this utility model, the integrated design of the working box simplifies the storage and release process of the probe trolley by the synergistic effect of the storage compartment and the door panel assembly. The door panel assembly automatically flips to form an inclined floor when the probe trolley drives out, eliminating the need for manual track construction and reducing operation steps. The limiting component fixes the probe trolley by a cylinder-driven baffle, ensuring stability during transportation and retrieval, while avoiding frequent plugging and unplugging of connecting wires and improving work efficiency.
[0016] 3. In this utility model, by setting the first cavity and the second cavity of the ground detection trolley to be independent of each other, it is convenient to separate the sensor module from other functional components for maintenance or upgrades; the limiting components of the work box and the cavity design of the base platform further simplify the internal structure, reduce the failure rate, and extend the service life of the equipment, which has certain application value and promotion value.

[0024] like Figure 1 , 2 As shown in Figure 3, a sonar pipeline detection device includes a working box 10, a detection trolley 20, and a sonar sensor 30. The working box 10 is used to store the detection trolley 20 and facilitate its entry and exit. The detection trolley 20 includes a first cavity 21 and a second cavity 22. The first cavity 21 and the second cavity 22 are independent of each other, and the second cavity 22 is located at the front end of the detection trolley 20. The sonar sensor 30 is installed in the second cavity 22. The detection trolley 20 has a cover plate assembly 23 on the side near the second cavity 22. The cover plate assembly 23 is used to flip and adjust to protect the sonar sensor 30 inside the second cavity 22.
[0025] In one embodiment, the cover plate assembly 23 includes a cover plate body 231, a connector 232, and an electric telescopic rod 233. The cover plate body 231 is used to seal and shield the second cavity 22. The connector 232 is fixedly mounted on the cover plate body 231. The electric telescopic rod 233 is mounted on the outer top wall of the detection trolley 20 near the first cavity 21. The piston end of the electric telescopic rod 233 is hinged to the connector 232.
[0026] In one embodiment, the cover plate body 231 has an L-shaped structure and is located on the side close to the second cavity 22.
[0027] In one embodiment, the work box 10 includes a storage compartment 11, a base 12, a limiting component 13, and a door panel assembly 14. The storage compartment 11 is used to store the probe trolley 20. The base 12 is located at the bottom of the storage compartment 11. The limiting component 13 is used to limit and fix the probe trolley 20 stored inside the storage compartment 11. An inlet and outlet 15 for connecting the storage compartment 11 is opened on one side of the work box 10. The door panel assembly 14 is installed on the outside of the inlet and outlet 15. The door panel assembly 14 is used to seal the inlet and outlet 15 of the work box 10 when the probe trolley 20 is stored. When the probe trolley 20 drives out, it flips open the inlet and outlet 15 and serves as the bottom inclined floor.
[0028] In one embodiment, a cavity 121 is provided in the middle of the bottom of the base 12, and an opening 122 is provided at the four top corners of the upper surface of the base 12 near the cavity 121.
[0029] In one embodiment, the limiting component 13 includes a cylinder 131, a bracket 132, and a baffle 133. The cylinder 131 and the bracket 132 are both located in the cavity 121. The piston end of the cylinder 131 is connected to the bracket 132. The baffle 133 is installed at the top four corners of the bracket 132 and is located directly below the opening 122.
[0030] In one embodiment, the door panel assembly 14 includes a panel 141 and a limiting block 142. The bottom two sides of the panel 141 are hinged to the work box 10. The limiting block 142 is installed on the work box 10 and located directly above the inlet / outlet 15. The limiting block 142 is used to limit and fix the panel 141 in a vertical state.
[0031] The working principle of this utility model is as follows: When in use, the detection trolley 20 is stored in the accommodating compartment 11 of the work box 10. The plate 141 of the door panel assembly 14 is fixed in a vertical state by the limiting block 142, sealing the inlet and outlet 15. The cylinder 131 of the limiting assembly 13 drives the bracket 132 to rise, causing the baffle 133 to pass through the opening 122 of the base platform 12 and abut against the four bottom corners of the detection trolley 20, thus achieving stable fixation during transportation or in a static state. When the detection task is started, the cylinder 131 retracts the bracket 132, and the baffle 133 disengages from the bottom of the detection trolley 20. The limiting block 142 of the door panel assembly 14 is unlocked, and the plate 141 flips outward around the bottom hinge point to form an inclined floor connecting the pipe inlet. The detection trolley 20 slides out of the work box 10 along the plate 141 and enters the pipeline. After the detection trolley 20 moves to the detection position, the electric telescopic rod 233 of the cover plate assembly 23 pushes the L-shaped cover plate body 231 to rotate around the hinge point of the connector 232. The cover body 231 gradually unfolds from the sealed state of the second cavity 22, adjusting the opening angle according to the pipeline environment (such as water depth). This exposes the sonar sensor 30 for detection while preventing the second cavity 22 from being completely open, thus preventing foreign object intrusion or mechanical collision. The sonar sensor 30 emits sound waves and receives reflected signals, transmitting the data in real time to the work box 10 or an external terminal through its built-in circuit. During the detection process, the independent design of the first cavity 21 and the second cavity 22 ensures that the sensor module does not interfere with other functional components (such as power supply and drive system), improving signal stability. After the detection is completed, the electric telescopic rod 233 drives the cover body 231 to reset, completely sealing the second cavity 22. The detection trolley 20 returns to the work box 10, the door panel assembly 14 resets and seals, and the limit assembly 13 fixes the detection trolley 20 again, ensuring safe transportation. The modular design allows the second cavity 22 to be disassembled separately for sensor maintenance or upgrades without disassembling the overall structure. 10-Working box, 11-Containing compartment, 12-Base platform, 121-Cavity, 122-Opening; 13-Limiting assembly, 131-Cylinder, 132-Bracket, 133-Baffle; 14-Door panel assembly, 141-Plate body, 142-Limiting block; 15-Entrance / exit; 20-Detection trolley, 21-First cavity, 22-Second cavity, 23-Cover plate assembly, 231-Cover plate body, 232-Connector, 233-Electric telescopic rod; 30-Sonar sensor.
