River sludge thickness detection device for hydraulic engineering

The invention relates to the technical field of sludge thickness measuring rods, in particular to a river sludge thickness detection device for a water conservancy project. Comprising a detection rod, the bottom end of the detection rod is slidably connected with a detection head, the detection head is fixedly connected and communicated with a central tube, the central tube is arranged to be a spline, the detection rod is fixedly connected with a spline ring, the central tube is fixedly connected with a limiting piece, the central tube is fixedly connected with a first fixing ring, and the detection rod is fixedly connected with a second fixing ring. And a limiting mechanism for positioning the detection head is arranged between the limiting piece and the detection rod. By limiting the limiting piece and controlling the movement of the limiting piece, the resistance of the detection head inserted into the bottom of the sludge is ensured to be the same, and the situation that the device cannot be stopped after
