Description
Technical Field
The utility model relates to a wave buoy or wave sensor detection device. In particular to a wave buoy or sensor simulation acquisition system based on a lead screw and a linear guide rail.
Background
The wave is one of the basic elements for marine hydrological observation, and the accuracy of wave observation data has great influence on marine engineering, marine traffic, marine fishery, marine research, marine military activities and the like.
The wave is monitored, and at present, two modes of manual visual inspection and instrument measurement are mainly adopted. During manual visual measurement, an observer visually observes and evaluates sea conditions and sea wave appearance characteristics, and judges and reads wave field values such as wave height, wave period and wave direction, and the like, so that the method has higher requirements on the skills of the observer. The wave buoy measuring technology mainly comprises a gravity acceleration type wave buoy, a pressure type wave buoy, an acoustic type wave buoy and the like, wherein the gravity acceleration type wave buoy is the main equipment for long-term, timed and fixed-point observation of waves at present. Hundreds of sets of wave buoys are distributed in coastal sea areas of China and are used for constantly monitoring wave field data of the coastal sea areas of China.
In order to ensure the accuracy and reliability of the wave field monitoring data, the gravity acceleration type wave sensor needs to be detected regularly (generally one year).
A double-ring truss type wave buoy calibrating device is built in 2004 by the national ocean Standard measuring center, and a wave buoy or a wave sensor with the diameter (0.5-1.0) m and the mass less than 180kg can be detected. During a detection test, firstly, a wave buoy or a wave sensor is additionally arranged on a fixture at one end of a truss, then the dynamic balance allocation work of the truss is completed, namely, a proper amount of balance weight is fixed at the other end of the truss, when the truss is opened, a brake part is in a free state and rotates to any position, the wave buoy or the wave sensor and the balance weight keep balance around a rotation center, then a control system controls the truss to rotate at a constant speed at a specified rotation speed, and the detection work is completed.
Various wave buoy or wave sensor detection device patent technologies have been published at home and abroad. The device comprises a self-lifting wave measuring buoy simulation test device (CN201420110403_ CN203759964U _ CN) and a wave/tide test verification system device and application thereof (CN201210311099_ CN102829799A _ CN) in China, and comprises a Waverider buoy accelerometer Calibration device (patent number US4158956A) published in the United states and an A Calibration device for wave height of ocean (patent number KR20170139468) published in Korea in foreign countries. The invention contents of the patent parts are similar and the methods are the same, and the controller is adopted to control the motor to rotate, drive the connecting piece (steel wire rope or nylon rope) to stretch and contract and simulate the sea surface fluctuation, so that the lifting motion of the wave buoy or the wave sensor connected with the connecting piece (steel wire rope or nylon rope) is realized. When the simulated sea surface rises, the wave buoy is vertically pulled up, and when the simulated sea surface falls, the wave buoy falls by self weight or is dragged downwards by a steel wire rope. Or the principle similar to a seesaw is adopted, a wave buoy is arranged on one side of the seesaw, and a balance weight is loaded on the other side of the seesaw, so that the wave lifting motion is simulated.
The detection technology plays a certain role in ensuring the accuracy of the wave quantity value in China, but has certain problems, and the detection technology is as follows:
(1) the wave height range of the existing detection device is small at present, waves with wave height of 3m can be simulated at most, and certain difference exists between the wave height of dozens of meters under actual sea conditions.
(2) When the existing detection device carries out wave buoy detection, wave full-factor (wave height, wave period and wave direction) detection tests cannot be carried out, at most, wave height and wave period parameter tests can be carried out synchronously in each test, and wave direction parameters need to be detected and tested independently.
(3) For wave lifting motion with acceleration larger than gravity acceleration g, the self-lifting wave measuring buoy simulation test device cannot be realized, and a certain difference exists from the actual sea condition simulation requirement.
(4) The steel wire rope or the nylon rope has certain elastic expansion change, larger simulation wave height error and lower precision, and can not meet the technical precision requirement of the wave buoy or the wave sensor which is new, upgraded and updated.
Disclosure of Invention
