Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of revetment crack detection, and particularly relates to a river revetment crack detection device. BACKGROUND

[0002] As an integral part of river ecosystems, river revetments have long played an important role in flood control, drainage, and protection of life and property safety of coastal residents in history. Traditionally, to enhance the erosion resistance and stability of revetments, hard materials such as stones and concrete are often used for construction. However, while providing strong protection, such hard revetments have also caused ecological problems, such as blocking the natural exchange of water and soil, disrupting the balance of river ecosystems, and reducing biodiversity. In recent years, with the awakening of global ecological environmental awareness and the deepening of the concept of sustainable development, ecological revetments have gradually become a new trend in river management. Such revetments take into full consideration of the integrity and ecological balance of river ecosystems, and through the ingenious combination of plant planting and engineering measures, they not only effectively protect the river bank, but also promote water self-purification, increase biodiversity, and restore the natural form and function of rivers.

[0003] River revetment crack detection is crucial to ensure the safety of water conservancy projects. Due to the long-term influence of various factors, cracks may appear in water conservancy projects. In order to timely discover these cracks, video detection technology is often used now. By shooting the surface of the revetment with a camera, workers can view and identify cracks in real time, so as to take timely measures for processing and ensure the safety of water conservancy projects.

[0004] Patent document CN217879091U discloses a river revetment crack detection device, which comprises a detector, a display screen provided on the detector, a control button provided on the side of the display screen, a connecting line provided on the top of the detector, and a detection head connected to the end of the connecting line away from the detector. It also includes a telescopic assembly provided on the detector, and an adjusting assembly provided on the telescopic assembly and connected to the detection head. This river revetment crack detection device sets a telescopic assembly on the detector, allowing workers to detect from the shore, effectively avoiding the need for workers to stand on the revetment for detection and causing safety accidents.

[0005] As in the prior art of the above-mentioned patent, the camera in the above-mentioned device is arranged from top to bottom, mainly for monitoring the crack situation on the river bank slope. However, this arrangement has a significant limitation, that is, it cannot effectively observe the situation near the river side of the revetment wall. Since the wall is close to the river, the observation requirement is to be carried out vertically to the outside of the wall, which makes it quite complex to observe through the traditional camera. In order to achieve this goal, it is necessary to constantly adjust the camera angle, which not only increases the difficulty of operation, but also significantly increases the cost of observation. Therefore, for the crack detection of the revetment wall close to the river, it is necessary to explore more efficient and economical monitoring methods to ensure the overall safety and stability of the water conservancy project.
