The specific installation application conditions of the invention are as follows:
When the water body to be detected is detected, the mud bottom measuring rod can penetrate into the water body to be detected in a uniform speed state, and as the bearing capacities of air, water, a mud layer and a hard bottom layer below the mud layer are different, the penetration resistance of the mud detecting head 8 is also different in the process of penetrating the mud detecting rod into the water body to be detected, when the mud detecting head 8 penetrates into the junction of the mud layer and the hard bottom layer (namely the mud layer bottom), the pressure value of the mud detecting head 8 is suddenly changed, so that whether the mud detecting head 8 penetrates into the mud layer bottom can be determined according to the penetration resistance of the mud detecting head 8, and in particular, a proper spring 8-5 can be selected according to the density of mud in different areas through experimental data in advance.
As shown in fig. 10 and 11, the bottom measuring rod of the silt is penetrated into the upper layer measuring rod of the silt to be touched forcefully towards the river bottom by using the stressed handle 10, when touching the hard river bed at the bottom of the silt, the probe 8-3 arranged at the bottom of the bottom measuring rod of the silt is stressed, the probe 8-3 pushes the contact rod 8-4, and the contact rod touches the touch switch 8-6 after overcoming the preset resistance of the spring 8-5, so that the vibrator 8-2 shakes to alarm, and the vibration is transmitted to a measurer holding the handle 10 by the stress through the bottom measuring rod of the silt to remind the measurer of touching the hard river bed. The measurer can read the depth of the river according to the position of the scale of the measuring rod on the upper layer of the silt at the moment. And according to the position of the scale of the measuring rod of the upper layer of the sludge and the position of the scale of the measuring rod of the bottom layer of the sludge, the difference value of the two is the thickness of the sludge layer. The altitude of the river and the mud is calculated from the data on the GPS satellite receiver 12.
After the measurement is finished, the touch switch 8-6 can be touched again by pressing the probe 8-3 so as to switch off the vibrator 8-2.
