[0028] The battery pack 5 is arranged in the lower bin section 12 and used as a ballast to make the float in an upright posture. The buoyancy state of the float 1 is set as: when working normally, the top of the float including the top cap is all above the water surface, and the bottom of the float including the lower bin section 12 is all below the water surface.

[0029] The depth transducer 3 is centrally arranged in the bottom of the float cylinder (i.e. the bottom seat hole of the lower bin section 12), and the water entry depth sensor and water temperature sensor 4 are also arranged in the bottom of the cylinder and located at one side of the depth transducer, for measuring the water entry depth and water temperature of the float. The waterproof charging interface 6 is also arranged in the bottom of the cylinder and located at the other side of the depth transducer, for charging the battery pack.

[0031] The main control circuit 21 provides an excitation voltage signal (300V AC) to the depth transducer 3 through the excitation circuit 22, the depth transducer 3 transmits the received detection signal back to the main control circuit board 21 through the signal amplification circuit 23 (amplification multiple: 10~100 times), and the water depth h1 is calculated by the time difference between the emitted sound wave and the bottom reflected sound wave.

[0032] In an embodiment, the main control circuit 21 can be built by using a single-chip microcomputer, and the depth transducer 3 can be selected as a 50k / 200k depth transducer.

Among them, according to the transmitted geographical position coordinates, the relationship between the device position change and time can be analyzed, and then the device moving speed can be calculated. According to the detected water depth h1, the water entry depth h2 and the inclination angle a, the water depth of the position where the device is located can be calculated.
