Description

Technical Field

[0001] This utility model belongs to the technical field of drainage pipe network detection equipment, and in particular relates to a retractable drainage pipe network detection device. Background Technology

[0002] With the continuous development of urban construction, drainage pipe networks, as an important component of urban infrastructure, are crucial for the normal operation of cities. However, because drainage pipe networks are located underground for extended periods, they are susceptible to damage, blockage, and deformation due to various factors such as sewage corrosion, geological subsidence, and external pressure.

[0003] Currently, there are various methods for inspecting drainage pipe networks. For example, some inspection devices use manual inspection, requiring inspectors to enter the pipes. This method not only presents a harsh working environment and significant safety risks to inspectors, but is also inefficient and difficult to conduct comprehensive inspections of large-area drainage pipe networks. Other devices use fixed-length inspection rods with probes, but these cannot adapt to drainage pipes of varying depths and lengths. When dealing with deeper or longer pipes, frequent changes of inspection rods are necessary, making the operation cumbersome and inefficient. Furthermore, some inspection devices struggle to accurately detect complex internal conditions within pipes, such as hidden cracks or cavities around the pipes, leading to the failure to promptly identify potential safety hazards.

[0004] Therefore, developing a retractable drainage network detection device that can adapt to pipes of different depths, has high detection accuracy, and is easy to operate is of great practical significance. Utility Model Content

[0035] In one embodiment of this utility model, such as Figures 1-3 As shown, a retractable drainage network detection device is provided, including a lower housing 1, an upper housing 2, a telescopic mechanism 3, a detection mechanism 4, and a buffer mechanism 5. One end of the upper housing 2 extends into the lower housing 1 and is connected to the lower housing 1. The telescopic mechanism 3 is movably connected to the upper housing 2 and abuts against the buffer mechanism 5. The detection mechanism 4 is connected to the telescopic mechanism 3, and the buffer mechanism 5 is connected inside the upper housing 2.

[0036] The telescopic mechanism 3 includes a lower rod 31 and a telescopic probe 32. The lower rod 31 is movably connected to the upper housing 2, and one end of the telescopic probe 32 is movably connected to the lower rod 31, while the other end extends out of the lower rod 31. This design allows for flexible adjustment of the extension length of the telescopic probe 32 according to the depth of the drainage pipe, adapting to different testing requirements.

[0037] The detection mechanism 4 includes a detection probe 41 and an ultrasonic sensor 42. The detection probe 41 is connected to the top side of the telescopic probe 32, and the ultrasonic sensor 42 is connected to the top of the telescopic probe 32 and positioned on one side of the detection probe 41. The detection probe 41 can directly photograph and observe the surface condition inside the pipeline, while the ultrasonic sensor 42 can use the principle of ultrasonic wave reflection to detect hidden defects, cavities, and the soil condition around the pipeline. The combination of the two improves the comprehensiveness and accuracy of the detection.

[0038] The buffer mechanism 5 includes an elastic buffer element and a buffer fixing seat 52. One end of the elastic buffer element abuts against the lower rod body 31, and the other end is sleeved on the buffer fixing seat 52 and abuts against the buffer fixing seat 52.

[0042] In another embodiment of this invention, the detection probe 41 is a CCD probe, which is fixedly connected to the top side of the telescopic probe 32. The CCD probe has advantages such as high resolution and low illumination, enabling it to clearly capture images of the inside of the drainage pipe in dimly lit environments.

[0043] In another embodiment of this invention, two ultrasonic sensors 42 are provided, both fixedly connected to the outside of the telescopic probe 32. The two ultrasonic sensors 42 can detect from different angles, further improving the accuracy and comprehensiveness of the detection and reducing blind spots.
