Embodiment Construction

[0015] The wave height meter and accelerometer dual-purpose calibration device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the wave height meter and accelerometer dual-purpose calibration device of the present invention includes an intelligent combination unit of LM guide rail and ball screw 1, a workbench 2, a wave height meter 3, a rotating bracket 4, a rotating mandrel 5, and an accelerometer 6. Electrical control box composed of PLC controller, touch screen, digital-to-analog conversion module, amplifier, pulse generator, etc. 7. Adjusting screw for leveling 8, frame 9, servo motor 10, photoelectric encoder 11, Water cylinder 12 etc. are formed. When the rotating bracket 4 is rotated to a vertical position by means of the rotating mandrel 5 and installed, the workbench 2 is in a vertical state, the wave height meter 3 installed on the workbench reciproc...

Abstract

The invention discloses a wave height recorder and accelerometer double-purpose calibration device. The device comprises an intelligent combined unit 1, a working table 2, a wave height reorder 3, a rotary bracket 4, a rotary spindle 5, an accelerator 6, a control box 7, an adjusting screw 8, a frame 9, a servo motor 10, an encoder 11 and a water cylinder 12, wherein the working table is in a vertical state when the rotary bracket 4 is rotated to a vertical position to be mounted by means of the rotary spindle 5, the wave height recorder mounted on the working table does reciprocating motion up and down, and the lower part of the working table is provided with the water cylinder for simulating seawater level so as to calibrate the wave height recorder; the working table is in a horizontal state when the rotary bracket 4 is rotated to a horizontal position to be mounted by means of the rotary spindle 5, and the accelerometer does horizontal reciprocating motion to calibrate the accelerometer; a control system controls a rotation speed and reciprocating convolution of a servo motor photoelectric encoder of the intelligent combined unit and controls the frequency and the amplitude of the calibration device; and compared with corresponding values of the wave height recorder and the accelerometer, the value achieves higher calibration accuracy.

Description

technical field [0001] The invention relates to a ship model test, in particular to a performance test of a sea state measuring instrument. Background technique [0002] The correctness of the sea state detection instrument has a direct impact on the correctness of the ship model performance test. The testing instrument is a non-standard equipment and has no centralized unit of measurement. I do not know the accuracy of the testing instrument during the previous use. In order to correctly identify the accuracy of the detection instrument, a set of calibration device is required to calibrate the sea state detection instrument to determine the correctness of the detection instrument. [0003] In order to solve the above problems, the present invention provides a dual-purpose wave height meter and accelerometer, a calibration device with good stability, convenient operation and high calibration accuracy. Contents of the invention [0004] In order to solve the above problem...
