Description

Technical Field

[0001] The utility model relates to the technical field of river channel root stone detection, in particular to a novel river channel root stone detection device. Background Art

[0002] Root stones, also called "root protection stones", are the lower protective stones of river embankments. The stability of embankment root stones is the most important condition for ensuring flood control safety. Timely discovery of the location and quantity of root stone changes is the key to taking preventive and supplementary measures and flood control safety. For many years, the status of underwater root stones has been estimated entirely by manual exploration. Manual exploration has problems such as high labor intensity, low work efficiency, labor and time, limited exploration depth, difficulty in positioning ships when the water is deep and the current is fast, and difficulty in ensuring the safety of detection personnel. Therefore, underwater basic detection technology has always been a key technical problem that needs to be solved urgently in river flood control. Non-contact underwater detection instruments can be used for detection, but there is currently no good mobile device to automatically complete the detection.

[0003] With the existing riverbed root stone detection device, due to the small detection head of the detection instrument, the water area detected by the device in a single trip is small when the device is moved. Therefore, the device needs to move back and forth too many times, resulting in low detection efficiency; and the detection head is easily stuck on the root stones at the bottom of the river. At this time, the detection arm cannot be shaken to solve the problem of the detection head being stuck, which causes the detector to be abnormal or damaged and unable to perform normal detection work.

[0004] Another example is the utility model patent with the publication number CN200944137Y, which discloses a mobile device for automatic detection of underwater root stones in a river channel, including a motor vehicle and a detection control device. The motor vehicle includes a frame, a bracket and a hydraulic pump. The detection control device includes an adjustment cylinder, a detection arm and a variable amplitude cylinder. The bracket is installed at the rear of the frame. The hydraulic pump is arranged on the frame. The rear of the detection arm is hinged to the upper end of the bracket, and the middle part is hinged to the piston rod of the variable amplitude cylinder. The variable amplitude cylinder is hinged to the frame. The adjustment cylinder is hinged to the bracket, and its piston rod is hinged to the detection arm. Each cylinder is connected to the hydraulic pump through an oil pipe and a reversing valve. The motor vehicle is a crawler motor vehicle. The front end of the frame is hinged with a balancing leg. A high-pressure oil pipe winder is installed on the bracket for automatically retracting and releasing the oil pipe. The detection arm is a telescopic structure of a sleeve type. The patent can walk on the shore through the crawler. However, if the river channel is too wide, the central area of ​​the river channel cannot be detected, so it can only be applied to narrower rivers. Utility Model Content
