[0034] The present application aims to provide a laboratory metrological verification device of a wave sensor to solve the problems in the prior art, and to detect the wave sensor before the wave buoy is assembled, thereby improving the accuracy of test results.

[0035] To make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-6 As shown in the drawings, the present application provides a laboratory metrological verification device of a wave sensor. The wave sensor is prior art, so it is not described in detail. The laboratory metrological verification device of the wave sensor comprises a driving device, a measuring device and a direction adjusting device. In the drawings, A is the driving device, B is the measuring device, and C is the direction adjusting device. The present application can detect the acceleration wave sensor. The structure and principle of the wave sensor belong to the prior art. The device of the present application is mainly used to simulate different sea wave conditions, so that the data detected by the wave sensor under the simulated sea wave conditions are compared with the standard data, and the metrological verification process of the wave sensor is realized. The driving device comprises a motor and a driver 1. The measuring device comprises a rotating rod 7, a bearing seat 4, a wave sensor mounting seat 10 and a counterweight 9. The counterweight 9 is a metal block with connecting through holes. The direction adjusting device comprises a base 11, a rotating disc 12, a scale disc 13 and a pin shaft 14. The orientation device comprises a synchronous pulley set. When working, the driving device drives the measuring device to rotate, and the synchronous pulley set keeps the wave sensor mounting seat 10 always in a horizontal state, realizes the static simulation of the sine characteristic motion of the sea wave, and accurately realizes the detection of the wave height, wave period, wave direction and other parameters of the wave sensor in cooperation with the direction adjusting device.

[0037] During the test, the wave sensor to be tested is installed on the wave sensor mounting seat 10, and the driving device is started to drive the measuring device to rotate. The driving wheel 5 of the synchronous belt wheel set in the measuring device is fixed on the bearing seat 4, the wave sensor mounting seat 10 is fixedly connected with the driven wheel through the rotating shaft arranged at one end of the rotating rod 7, and the driving wheel 5 and the driven wheel are connected in tension through the closed synchronous belt. During the test, the driving device drives the measuring device to rotate, the driven wheel of the synchronous belt wheel set always rotates relative to the driving wheel 5, the rotating rod 7 drives the driven wheel and the wave sensor mounting seat 10 to rotate synchronously, the driven wheel rotates synchronously in the opposite direction of the rotating rod 7 under the driving of the synchronous belt, the wave sensor mounting seat 10 fixedly connected with the driven wheel rotates synchronously, the function of keeping the wave sensor mounting seat 10 always horizontal is realized, and the static simulation of the sine characteristic motion of the sea wave is realized, so that the wave height, wave period, wave direction and other parameters of the wave sensor can be accurately detected in cooperation with the direction adjusting device.

[0038] In order to further improve the transmission stability, the connecting point of the driving device and the rotating rod 7 is located between the counterweight 9 and the wave sensor mounting seat 10. The operator can select a suitable counterweight 9 according to the weight of the wave sensor carried by the mounting seat and different sine curves of wave height, so as to ensure the dynamic balance of the rotating rod 7 during rotation. The counterweight 9 and the rotating rod 7 are detachably connected.

[0039] In an embodiment, the rotating rod 7 is a rectangular tube structure, which is convenient for connecting the rotating rod 7 with the driving device.

[0040] In an embodiment, the output end of the motor is fixedly connected with a transmission shaft 3, the transmission shaft 3 is fixedly connected to the rotating rod 7 at the end, and the bearing seat 4 fixed to the top of the mounting rack is arranged between the transmission shaft 3 and the rotating rod 7. The bearing seat 4 is provided with a bearing matched with the transmission shaft 3, so as to ensure smooth rotation of the transmission shaft 3. A plurality of mounting holes are formed in the rotating rod 7 at one end in the axial direction, the mounting holes are formed as mounting seat mounting positions, the wave sensor mounting seat 10 is installed on different mounting seat mounting positions through the rotating shaft, and the response of each parameter of the wave sensor under different wave height conditions during detection is realized.

[0041] In order to improve the stability during detection, a shock pad is arranged on the wave sensor mounting seat 10, the shock pad is made of flexible material, and the shock pad can absorb part of the vibration to improve the stability of the wave sensor.

[0042] In order to improve the convenience of wave direction detection process, the direction adjusting device is arranged at the bottom of the mounting rack, can be divided into 16 directions, and is provided with a pin shaft 14 to fix the direction.

[0043] The laboratory metering and testing device of the wave sensor of the present application works as follows: the driving device is started, the output end of the driving motor rotates at a constant speed, and the rotating shaft 3 drives the rotating rod 7 to rotate at a constant speed. The rotating rod 7 drives the driven wheel and the wave sensor mounting seat to rotate synchronously. Since the driven wheel in the synchronous belt wheel set always rotates relative to the driving wheel 5, the driving wheel 5 is fixed, and under the action of the synchronous belt, the driven wheel rotates synchronously with the rotating rod 7, and at the same time, it also rotates reversely. During the reverse rotation, the rotating shaft drives the wave sensor mounting seat 10 fixedly connected thereto to rotate reversely, so as to ensure that the wave sensor mounting seat 10 always maintains a horizontal state during the rotation of the rotating rod 7, realizes the static simulation of the sine characteristic motion of the sea wave, and before each simulation, the direction adjusting device is used to rotate the mounting rack to the set scale position of the dial 13, and then the pin shaft 14 is used to fix the mounting rack at the position. Then, the driving device is started to drive the rotating rod 7 to rotate for simulation, and then the wave height, wave period, wave direction and other parameters of the wave sensor are accurately detected, which are used for comparison with the standard parameters to realize the detection and calibration of the wave sensor. The present application has reasonable structure design, stable working process and ideal application effect. In order to avoid the influence of the device components on the detection accuracy, all the components except the motor are made of non-magnetic materials, and the motor is a servo motor 2, and the shell is wrapped with a shielding net.

[0044] In one embodiment, in combination with Figure 1 It can be seen that the circular table structure at the bottom of the driving device and the measuring device is the mounting rack, the top of the mounting rack is provided with the driving device, the driving device is in transmission connection with the measuring device to drive the rotating rod 7 of the measuring device to rotate, and the rotating process of the rotating rod 7 is used for simulating the wave fluctuation state; the bottom of the mounting rack is connected to the direction adjusting device, and the direction adjusting device can rotate the mounting rack by a set angle, and the rotating rod 7 is rotated in cooperation with the direction adjusting device to realize the static simulation of the sine characteristic motion of the sea wave.

[0045] In the present embodiment, the wave sensor mounting seat 10 is used for fixing and placing the wave sensor, and during the rotation of the rotating rod 7, the wave sensor rotates with the rotating rod 7. By detecting the transmission data of the wave sensor, the simulation metering and testing of the wave sensor are realized.

[0046] In an embodiment, the rotating shaft is arranged through an end of the rotating rod 7 away from the counterweight 9, and the driven wheel can drive the wave sensor mounting base 10 to rotate synchronously through the rotating shaft, the rotating direction of the driven wheel is opposite to the rotating direction of the rotating rod 7, the bottom of the bearing seat 4 is fixed to the top of the mounting rack, the driving wheel 5 is fixed to the side of the bearing seat 4 away from the motor, and the driving wheel 5 is coaxially arranged with the bearing seat 4, bearings are arranged in the bearing seat 4 and the driving wheel 5, and the end of the transmission shaft 3 away from the motor is sequentially arranged through the bearings of the bearing seat 4 and the driving wheel 5, and is fixedly connected with the rotating rod 7; the driving wheel 5 and the driven wheel are connected through the closed synchronous belt 6. Since the driving wheel 5 is fixed by the bearing seat 4 and cannot rotate, the driven wheel can rotate with the rotating shaft. When the driven wheel and the rotating shaft rotate with the rotating rod 7, the angle of the synchronous belt 6 changes, the direction of the friction force of the synchronous belt 6 changes, and the driven wheel rotates synchronously with the rotating rod 7 and also rotates around the rotating shaft as the center, and the rotating direction is opposite to the rotating direction of the rotating rod 7. In this way, the rotating rod 7 drives the rotating shaft and the wave sensor mounting base 10 to rotate and deviate, but the wave sensor mounting base 10 rotates synchronously with the rotating shaft and the driven wheel in the direction opposite to the rotating direction, so that the rotating angle of the wave sensor mounting base 10 is offset by the rotating angle of the rotating rod 7. In this way, the wave sensor mounting base 10 is always in a horizontal state during the rotation of the rotating rod 7, so that the wave sensor is always fixed on the horizontally arranged wave sensor mounting base 10, thereby simulating the real state of the wave sensor in water.

[0047] In an embodiment, in order to ensure that the synchronous belt 6 can drive the driven wheel to rotate, the embodiment is provided with a tension pulley set 8 on the rotating rod 7, the tension pulley set 8 is located on the end of the rotating rod 7 close to the transmission shaft, specifically, the tension pulley of the tension pulley set 8 abuts against the synchronous belt 6 between the driving wheel 5 and the driven wheel, so that the synchronous belt 6 always has a large tension, and the synchronous belt 6 is arranged in parallel with the rotating rod 7 as a whole. When the synchronous belt 6 and the rotating rod 7 synchronously swing and deviate in angle, since the driving wheel 5 is fixed and cannot rotate, the synchronous belt 6 drives the driven wheel to rotate in the direction opposite to the swinging direction of the synchronous belt 6.

[0048] In order to adjust the circumferential position of the device, in an embodiment, the dial 13 is fixed on the horizontal ground, and the upper surface of the dial 13 is provided with scales; the dial 13 is provided with a rotating disc 12 coaxially arranged with the dial 13, and the rotating disc 12 is located inside the scales; the rotating disc 12 is provided with a base 11 fixedly connected with the bottom of the measuring device. By rotating the rotating disc 12, the driving device and the measuring device can be driven to rotate synchronously in the circumferential direction. After being rotated to a set angle, the position is fixed by using a pin shaft 14, and then the rotating process of the rotating rod 7 can be realized. The static simulation of the sine characteristic motion of sea waves can be realized, and the parameters of the wave sensor, such as wave height, wave period and wave direction, can be accurately detected.

[0049] In an embodiment, the wave sensor mounting seat 10 is provided with a plurality of size mounting holes for mounting wave sensors of different sizes to meet the measurement of wave sensors of different sizes; meanwhile, the plurality of size mounting holes can adjust the position of the wave sensor during installation, so that the wave sensor is installed at the center position of the wave sensor mounting seat 10, further ensuring that the wave sensor mounting seat 10 is initially in a horizontal state.

[0050] In an embodiment, the rotating shaft 7 is provided with a plurality of mounting holes of the wave sensor mounting seat 10 in the axial direction, the rotating shaft is movably arranged in the mounting hole at the corresponding position, and the wave sensor mounting seat 10 is installed in different mounting holes through the rotating shaft to realize the detection of the response of each parameter of the wave sensor under different wave height conditions.

[0051] In an embodiment, when the laboratory measurement and calibration device for a wave sensor of the present application works, first, the direction adjusting device is used to rotate the driving device and the measuring device to the set scale position of the dial 13, and then the pin shaft 14 is used to fix the rotating disc 12 at the set scale position of the dial 13. The inside of the dial is provided with a plurality of pin shaft holes, the pin shaft 14 is inserted into the corresponding pin shaft hole through the rotating disc 12, and the relative fixation between the rotating disc 12 and the dial 13 can be realized. Then, the driver 1 is started, the output shaft of the servo motor 2 is uniformly reciprocating rotated, and the output shaft of the servo motor 2 drives the rotating shaft 7 to rotate uniformly. The driven wheel in the synchronous pulley set always rotates relative to the driving wheel 5. Since the driving wheel 5 is fixed by the bearing seat 4, the driving wheel 5 is not moving, and the friction direction between the synchronous belt 6 and the driven wheel changes during the rotation of the rotating shaft 7, thereby driving the driven wheel to rotate in the opposite direction of the rotating shaft 7, i.e. under the premise that the driving wheel 5 is fixed, the straight line distance between the driven wheel and the driving wheel 5 does not change, and the driven wheel which can rotate synchronously with the rotating shaft is swung around the driving wheel 5 through the closed synchronous belt 6. During the swinging process, the driven wheel will rotate in the opposite direction of the rotating shaft, so that the wave sensor mounting seat 10 fixedly connected with the driven wheel rotates in the opposite direction of the rotating shaft, so as to always keep the wave sensor mounting seat 10 in a horizontal state, realize the static simulation of the sine characteristic motion of the sea wave, accurately detect the wave height, wave period, wave direction and other parameters of the wave sensor, and the structure design of the present application is reasonable, the working process is stable, and the application effect is ideal. In order to avoid that the device components affect the detection accuracy, except for the servo motor 2, the other components are made of non-magnetic materials, and the motor is wrapped with a shielding net.

[0052] The principles and implementation manners of the present application are described by using specific examples in the present application, and the above examples are only used for helping to understand the method of the present application and its core idea; meanwhile, for the general technical personnel in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed. In conclusion, the content of the present specification should not be understood as the limitation of the present application.
