The detection device is composed of a detection device and a deep-sea mining reverberation environment simulating device, wherein the detection device is composed of a probe constantly-swinging mechanism, a probe linearly-moving mechanism, a probe front-and-back moving mechanism and a probe up-and-down moving mechanism, and the deep-sea mining reverberation environment simulating device is composed of a stirring device and a hopper. According to the method for simulation of the deep-sea mining reverberation environment ultrasonic microtopography, sampling is conducted on the earth surface at different intervals in the horizontal direction and at different altitudes through the swinging or horizontal moving of a probe of the detection device, all collected data are loaded to an industrial personal computer, data analysis and reconstruction of the microtopography are conducted, and the purpose of detection of the microtopography in the mining reverberation environment is achieved.

Description

technical field [0001] The invention belongs to the technical field of underwater sonar detection, and in particular relates to an ultrasonic micro-terrain detection device and method for simulating the reverberation environment of deep-sea mining, especially for simulating complicated marine working conditions in a high-precision, short-distance ultrasonic micro-terrain detection system detection devices and methods. Background technique [0002] There are abundant mineral resources at the bottom of the ocean. With the development of science and technology and the depletion of land resources, human beings are marching towards the development of marine resources at an unprecedented speed. The development of marine mineral resources has become a research focus at home and abroad. The first step of development is to detect the topography of the mining area, which provides important theoretical and practical basis for the optimal mining of minerals.

Problems solved by technology

This method does not consider the reverberation environment during actual mining, but the actual situation is that when the mining equipment is operating underwater, the mining head breaks the ore, which will definitely make the nearby waters turbid; and this method does not consider the difference between the front and rear of the detection head In the case of different distances and different heights, the different positions of the probe in the actual mining reverberation environment determine the reverberation strength of the detection area, which will also have a great impact on the detection results
