Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 1-3; The field, waters 1, variable frequency drives 6, push wave baffle plate 4, wave energy detection device 9 and the computer 7 that comprise the wave simulation system; One end of the field, waters 1 of described wave simulation system is equipped with promotion dish 3 and push wave baffle plate 4; Described push wave baffle plate 4 is installed on the promotion dish 3 with being biased; The central rotating shaft level of push wave baffle plate 4 is installed on the both sides of the field, waters 1 of wave simulation system, and described promotion dish 3 links to each other with variable frequency drive motors 5, variable frequency drives 6 and computer 7 successively, is placed with wave sensor 8 and wave energy detection device 9 in the field, waters 1 of described wave simulation system.
The contrast accompanying drawing specifies the effect of each parts below:
The field, waters 1 of wave simulation system, make the carrier water source of ripple.
Wave 2 promotes at wave to produce a certain amount of wave under the effect of baffle plate.
Promotion dish 3 when motor rotates, will drive this promotion dish to-and-fro motion, drive the motion of push wave baffle plate.
Push wave baffle plate 4 is the direct transfer units of energy that produce wave.
The variable frequency drive motors 5 that has gear, this motor have variable speed, variable-speed function, under the control of variable frequency drives, and will be according to given push pedal speed operation.
Variable frequency drives 6, the speed governing parameter that this driver will provide according to computer, the frequency-conversion processing through the regulation control plate of internal drive has accordinged to specified value, and the control motor stabilizing is moved on given tachometer value.
The dedicated computer system 7 that DSP+FPGA constitutes with receiving the wave parameter instruction that the operator gives, exports variable frequency drives 6 to; After the driver operation, the actual measured value with gathering the wave sensor compares computing; In order to adjustment output, revise the wave parameter value.(schematic diagram is seen accompanying drawing 2)
Wave sensor 8, it passes to computer system after being responsible for the energy acquisition of wave detected, for the parameter adjustment of computer system provides foundation.
Wave energy detection device 9, one's respective area are the working platform zone.That the transducing head of required wave environment here will obtain will be given, stablize wave energy, be used to design new wave energy transducing head or optimal design parameter or the like.
Working procedure of the present invention is such.
Whole device is divided into two big zones:
(1), wave making epparatus zone (wave energy generation)
This zone mainly is to be provided with for the equipment that produces wave energy.
(2), simulation wave energy working zone
This zone is exactly so-called work simulation test platform, and tested wave transducing head will move under the environmental conditions of the parameter of setting in this environment.
After operator (artificer of wave transducing head or operator) set required wave energy on computers, computer at first will carry out the quantification of index to be shifted, and becomes frequency-conversion drive apparatus 6 receptible numerical signals.
Behind this signal given, variable frequency drives will produce the speed governing operation power electric energy of motor rotation, will make the variable-frequency motor rotation; To drive after the motor rotation and promote disc spins 3; Because the push wave baffle plate is to be installed on the promotion dish 3 with being biased, and its central position can rotate, therefore; The front and back position that promotion dish 3 rotation backs drive the push wave baffle plate moves (motion of component is up and down also arranged), has produced wave energy.
At this moment, the wave sensor passes to computer system with the wave energy information that collects, and computer system will be adjusted, and above-mentioned repeatedly then process tends towards stability up to the wave energy that produces, with being stabilized in the setting value that the operator gives.
After wave energy was stable, in the working zone (i.e. 9 position) of this device, the design of wave energy transducing head and debugging work just can be carried out.
Be not difficult to find; Wave energy dry run environment of the present invention is directly for the wave energy artificer a requisite design optimization test platform to be provided; In design and process of the test; Since its wave energy, current can environment reproducible, therefore, for the artificer in this field provides a kind of indispensable in the industry analogue test platform.
Because this system has adopted the computer system simulation method of operating, therefore, whole operation process simple and stable is reliable, and behind the wave energy numerical value that an appointment is set, in a short period of time, system just gets into stable dry run environment.
