Description

Wave height inclination integrated transducer

The utility model belongs to the ocean technical field of measurement and test, specifically a kind of senser element of measuring wave height and wave tilt.

At present, be used to measure the sensor of wave height and inclination in the world, that adopts is two independently wave height and inclination sensor is measured, be split type, its measurement point is positioned on the different barycenter, and its deficiency is a complex manufacturing, and measuring error is big, install and use inconvenience, very big difficulty is also arranged when measuring use.

For solving above split type deficiency, the purpose of this utility model provides a kind of wave height inclination integrated transducer, two sensors is put together, solved effectively because the measurement point of two sensors of branch bulk measurement wave height and inclination is to be positioned at the systematic error that different barycenter produce above.

Structural design of the present utility model is achieved in that wave height inclination integrated transducer is mainly by gimbal, pendulum, the acceleration of gravity meter, two orthogonal angle gauges and metering circuit are formed (as shown in Figure 1), wherein gimbal is made up of a universal joint, the pendulum of ining succession in the universal joint lower end, the acceleration of gravity meter is placed in the pendulum below the gimbal, on two orthogonal axles on the universal joint, be fixed with the angle gauge of two quadratures, the gimbal top is fixed on the A-frame, angular displacement sensor has been sidelong in gimbal bottom one, opposite side is added with counterweight, the device top is a protective cover, it below the protective cover gland bonnet, spacing cushion rubber is equipped with in the pendulum outside, and whole device outside is a housing; Metering circuit is made up of two-way, wherein a route accelerometer connects modulator, through low-pass filter, two-integrator connects Hi-pass filter, another road is X, the Y-axis inclinometer, connect modulator, through traffic pilot, the coupling number conversion directly connects microprocessor, low-pass filter output connects traffic pilot (as shown in Figure 2), because pendulum is under action of gravity, has the self-poise restore funcitons, make pendulum remain surface level, two angle gauges are measured two quadrature components of inclination respectively when wave tilt, the synthetic wave tilt angle that is of these two quadrature components.

The advantage of the utility model: simple in structure, two sensors is fitted together, and is easy to install, and the measuring accuracy height is to have met the wave measurement principle.

The utility model detailed structure is provided by following examples and accompanying drawing.

Fig. 1 is a wave height inclination integrated transducer structure principle chart;

Fig. 2 is integrated measurement circuit block diagram for wave height tilts.

Its structure as shown in drawings, 1 is protective cover, is contained in the instrument top, 2 is gland bonnet, in protective cover, below 3 be A-frame, gimbal 4 is housed on the support 3, hung pendulum 7 below the gimbal 4, gimbal one side 8 is an angular displacement sensor, and opposite side 9 is a counterweight, with the angular displacement sensor symmetry; Be contained in pendulum, gimbal 4 both sides respectively, 10 is the gravity accelerometer on the pendulum mirror 7, and 11 is angle gauge on gimbal 4, on two orthogonal axles of universal joint, 6 is spacing cushion rubber above the pendulum, and whole device outside is a housing 5, and the sensor measured signal connects with microprocessor by lead.

Measuring principle is generally can regard wave by the different sine-wave superimposed of countless various amplitudes, different frequency, out of phase and direction as to form.When wave surface water particle is done periodic vibration, each water particle just has definite normal acceleration in a flash at certain, there is a fixing inclination angle on the corrugated at this water particle place to surface level, and when water particle moved, pairing normal acceleration and inclination angle, corrugated also changed thereupon.The heave displacement on corrugated obtains by normal acceleration, the measurement at inclination angle is by the inclination angle being resolved into two orthogonal angle components, recorded by two orthogonal angular transducers, synthetic by to the longitudinal and transverse inclination angle of two quadratures obtains the inclination angle on corrugated.
