Multi-parameter measurement device for ocean currents with wide depth range

Abstract

The invention provides a width-depth range ocean current multi-parameter measuring device. The width-depth range ocean current multi-parameter measuring device comprises four functional modules for measuring the flowing direction, the flowing speed, the temperature and the seawater pressure intensity of an ocean current. The flow-direction measuring module is mainly composed of a cross-fluid-shaped guide empennage, a hollow rotating shaft and a rotating transformer. The flow-speed measuring module comprises an impeller, an impeller sensing piece and a proximity switch, and the impeller is driven by the ocean current to rotate. By means of the width-depth range ocean current multi-parameter measuring device, the problems of the pressure intensity at different depths, seawater corrosion and the like can be well solved. Hardware of a lower computer of a monitoring system can collect and process information including the flowing speed, the flowing direction, the temperature and the pressure intensity of the ocean current through a sensor, a high-speed single-chip microcomputer and a signal collecting and processing circuit in real time; changes in parameters are monitored and displayed through a monitoring interface of an upper computer of the monitoring system in real time, and the parameter information is stored. The parameters of the flowing direction, the flowing speed, the temperature, the seawater pressure intensity and the like of the ocean current from shallow sea to deep sea are monitored by the monitoring system in real time, and the importance information is provided for exploring the ocean environment.

Description

technical field [0001] The invention relates to an ocean current measuring device, in particular to a wide depth range ocean current multi-parameter measuring device. Background technique [0002] With the rapid increase of the world's population, the available resources on land are becoming more and more scarce. Humans have gradually expanded the exploitable field from land to sea, so a large number of deep-sea operation equipment came into being, and the marine environment is harsh and complex, which will affect deep-sea operations. The working conditions of the equipment, especially the parameters such as the flow rate, flow direction, temperature and pressure of the seawater, will determine whether it can work normally or what kind of working mode it adopts. The environment is important. [0003] At present, many universities and units at home and abroad have carried out research on devices for measuring flow parameters, developed a series of products and put them into ...

AI Technical Summary

Problems solved by technology

[0003] At present, many universities and units at home and abroad have conducted research on devices for measuring flow parameters, developed a series of products and put them into use, but there are still many deficiencies, most of which are only suitable for shallow water environments, or are relatively structural and functional. Single, and there is a lack of in-depth research on devices that can be applied to deep-sea high-pressure, corrosive environments, and simultaneously measure ocean current velocity, flow direction, temperature and pressure parameters

[0004] Such as Chinese patent (application number is CN270727045962) provides a kind of flow rate measurement device, and it is made up of flow rate measurement sensor, microprocessor and display driving circuit, and flow rate measurement sensor is made up of pitot tube, is respectively arranged on the total pressure of pitot tube front end and side. The sensor is composed of sensors, which measure the flow rate of water flow by measuring the pressure inside the pitot tube, but the device has a single structure and function and cannot measure the flow rate of water flow

Such as the flow velocity and flow direction measurement device provided by the Chinese patent (application number CN270710123234), it integrates two impeller flow measurement sensors orthogonally into one body, and puts them into the fluid to obtain mutually orthogonal flow velocity vectors, and calculates the data , then calculate the flow velocity and flow direction and other parameters, but this device is only suitable for relatively shallow fresh water, it does not consider the pressure resistance and corrosion resistance, and cannot be applied in the deep sea environment

The Chinese patent (application number is CN271227443336) provides a rotating flow rate and flow direction measurement device, which does not consider pressure resistance and corrosion resistance, and cannot be used in deep sea environments, and the depth of use of the device is greatly limited.
