Abstract

The invention belongs to the technical field of measuring devices, and particularly relates to a device for measuring seawater fluctuation based on surface acoustic waves. The device comprises four floating blocks, the middle part of each floating block is provided with a middle fixing part, the middle fixing parts are connected with lifting ropes through clasps, and the lifting ropes are provided with tension detection devices. Each tension detection device comprises an input interdigital transducer, an output interdigital transducer, an elastic dielectric material and a fixing part, the upper ends of the input interdigital transducers and the upper ends of the output interdigital transducers are interdigital transducer motor access ends, and the fixing parts are fixedly connected with the lifting ropes. The four floating blocks are arranged, when the coming direction of seawater is different, the voltages output by the tension detection devices on the four lifting ropes are different, and the direction of a seawater fluctuation device and the size of seawater fluctuation can be judged by judging the sizes of the voltages.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a device for measuring seawater fluctuations based on surface acoustic waves. Background technique [0002] Ocean is the general term for the most extensive body of water on earth. The surface of the earth is divided into vast waters connected to each other by the continents called the ocean. The central part of the ocean is called the ocean, and the edge part is called the sea. They communicate with each other to form a unified water body. When carrying out marine farming, it is necessary to detect the local seawater fluctuations , used to detect whether marine farming can be carried out locally. [0003] In the prior art, it is difficult to measure the fluctuation of seawater, and it is difficult to detect the direction and magnitude of the fluctuation of seawater. Contents of the invention [0004] The object of the present invention is to provide a device for me...
