Whole detector floats through floating subassembly 5 and sets up on the water, can not contact fixedly with water bottoms such as riverbed or seabed, consequently, even produce and rock, can not cause the damage yet, has also avoided simultaneously because of the too dark condition emergence that leads to unable installation of the degree of depth of water, has enlarged the depth of water survey's scope. In addition, because of whole ratio detector is in free floating state, when needing to be changed the measuring position, only need through the ship pull can, need not to dismantle with the water bottom, efficiency when having improved the multiple spot measurement.

When the device is actually used, the whole device is placed in a measured water body, the transducer 1 emits sound waves, the distance between the transducer and the echo interception plate 3 is determined, the calibration is carried out, and then the depth of the water body is confirmed through sound wave signals reflected at the bottom of the water body and received by the transducer 1.

Further, the measuring rod 2 is placed in the water body in an inclined state or a horizontal state.

In the present embodiment, the measuring stick 2 is placed in the water body obliquely based on fig. 2. Because of rivers in the water flow along the depth direction and change great, and whole device is in the floating state, receives the influence of rivers easily, consequently, when transducer 1 and echo interception board 3 apart from certain, the measuring stick 2 that is the tilt state or is the horizontality is less for the water degree of depth that traditional vertical state's measuring stick 2 covered, and the change that receives water impact is littleer, makes whole measuring stick 2 more stable.

Wherein the shorter suspension cable 6 is connected to the side of the measuring rod 2 close to the transducer 1 and the longer suspension cable 6 is connected to the side of the measuring rod 2 close to the echo baffle 3. The measuring rod 2, when placed in a body of water, hangs under the influence of gravity to achieve its inclination. Similarly, when the lengths of the two suspension cables 6 are the same, the measuring rod 2 is in a horizontal state.

It should be noted that the above embodiment is not intended to limit the number of suspension cables 6, and in other embodiments than the above embodiment, the number of suspension cables 6 may be three or four, etc., according to actual conditions. The length of the suspension cable 6 is gradually increased from one side of the measuring rod 2 close to the transducer 1 to one side of the echo interception plate 3, so that the whole measuring rod 2 is ensured to be in an inclined state; alternatively, the lengths of the suspension cables 6 are the same, so that the whole measuring rod 2 is ensured to be in a horizontal state.
