For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-Figure 4 The utility model discloses a multi-beam depth sounding device, comprising: a sleeve 1, a sound velocity profiler body 2 is arranged inside the sleeve 1, a protective cover 3 is arranged at the bottom end of the sound velocity profiler body 2, the protective cover 3 is a cylindrical structure, a hollow opening is opened around the outer side of the circumference of the protective cover 3, a protective net 4 is connected to the protective cover 3 through the hollow opening, an electric telescopic rod 5 is fixedly installed on the inner wall of the top end of the sleeve 1, a guide rod 6 is fixedly connected to the inner wall of the top end of the sleeve 1 adjacent to the electric telescopic rod 5, and a cutting knife 7 is arranged on the inner side of the opening at the bottom end of the sleeve 1.

[0019] Combination Figure 2 and Figure 4 As shown, the interior of the sleeve 1 is a circular structure, and a movable ring 8 is fixedly connected to the outer side of the circumference of one end of the sound velocity profiler body 2 close to the protective cover 3. The movable ring 8 is not only convenient for the electric telescopic rod 5 to drive the sound velocity profiler body 2 to rise, but also can ensure the stability of the structure between the inner side of the sleeve 1. A sliding hole 801 is opened on the side of the movable ring 8 facing the guide rod 6. The outer circle diameter of the movable ring 8 is the same as the inner circle diameter of the sleeve 1. There are two electric telescopic rods 5 and two guide rods 6. The output end of the electric telescopic rod 5 is fixedly connected to the movable ring 8, and the guide rod 6 is slidably connected to the sliding hole 801.

[0020] Among them, the cutting knife 7 is an annular double-edged knife structure, so that the cutting knife 7 is convenient for cutting weeds, and the cutting knife 7 is facing downward. A screw rod 9 is arranged on the outer side of the circumference of the bottom end of the sleeve 1, and the cutting knife 7 is convenient for installation or removal through the screw rod 9. The screw rod 9 extends to the inner thread of the sleeve 1 to connect the cutting knife 7. The sound velocity profiler body 2 is located at one end of the protective cover 3 and a detection head 10 is arranged. The protective net 4 is made of rigid material. A fixing block 601 is fixedly connected to the bottom end of the guide rod 6, and one end of the fixing block 601 is fixedly connected to the inner wall of the sleeve 1.

[0021] Specifically, when the utility model is used, the movable ring 8 can be driven to descend by operating the electric telescopic rod 5, and then the movable ring 8 and the sound velocity profiler body 2 are lowered, and then the sound velocity profiler body 2 and the detection head 10 and the protective cover 3 are lowered, and the detection head 10 and the protective cover 3 are extended out of the sleeve 1. When moving and detecting in water, the detection head 10 can be effectively protected by the protective cover 3 and the protective net 4. After use, the movable ring 8 can be driven to rise by operating the electric telescopic rod 5 again, and then the sound velocity profiler body 2, the protective cover 3, and the detection head 10 can be retracted into the sleeve 1. In the retraction process, if there are weeds entangled on the outside of the protective cover 3, the weeds will be cut off by the cutting knife 7, and then the cut weeds will automatically fall off, thereby ensuring that there is no obstruction on the outside of the protective cover 3.

[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
