Seabed sand wave landform motion detection device based on MBES

Abstract

The invention provides a seabed sand wave landform motion detection device based on MBES, and relates to the technical field of seabed sand wave landform motion detection. The MBES-based seabed sand wave geomorphic motion detection device comprises an outer cylinder, three diagonal planes are arranged at the lower end of the outer cylinder, Doppler velocimeters are arranged at the diagonal planes, an electric push rod is fixedly connected to the upper inner wall of the outer cylinder, and a pressing frame is fixedly connected to the output end of the electric push rod; and the lower side wall of the outer cylinder is rotationally connected with a rotating inner seat, a second motor is arranged in the lower side wall of the outer cylinder, the output end of the second motor is fixedly connected with a gear, and outer teeth meshed with the gear are arranged on the outer side face of the middle of the rotating inner seat. According to the multi-beam echo depth sounder, the flow velocity of water flow in the water body can be measured through the Doppler current meter, then the flow direction of the water flow can be obtained, the blocking cover faces the water flow under the driving of the motor, the interference of the water flow on the multi-beam echo depth sounder is reduced under the action of the resonator, and the detection reliability is improved.

Description

technical field [0001] The invention relates to the technical field of seabed sand wave landform movement detection, in particular to a seabed sand wave landform movement detection device based on MBES. Background technique [0002] The ocean is rich in resources, and scientific cognition and efficient development and utilization of the ocean are conducive to the country's maintenance of marine rights and interests and the realization of sustainable development, which requires detailed and accurate information on the seabed topography as a guarantee. In addition, river safety, silt excavation, reservoir monitoring and underwater archaeology must also obtain underwater topographic information. Therefore, the demand for high-precision and high-resolution underwater topographic information is increasing, and the value of related detection technologies is constantly emerging. [0003] Among them, the multi-beam echo sounder is an important tool for the detection of seabed sand ...
