Description

Technical Field

[0001] The utility model relates to the technical field of acoustic Doppler flow profiler testing, in particular to a simulation testing device suitable for high-frequency ADCP. Background Art

[0002] An acoustic Doppler current profiler (ADCP) features multiple transducers capable of transmitting and receiving reflected sound waves in different directions. By utilizing the Doppler frequency shift effect and calculating the frequency shifts in different directions, the three-dimensional flow velocity of the water body can be determined. Currently, the commonly used methods for measuring the flow velocity and direction of high-frequency ADCPs are tank trailer tests and synchronous comparison tests. Synchronous comparison tests require a certified high-frequency ADCP and the one to be tested to be mounted on a vessel or moored for comparison testing on a lake or at sea. This method involves renting a vessel for operation on a lake or at sea, which is expensive and time-consuming, making it unsuitable for factory inspection of high-frequency ADCPs. Furthermore, tank trailer tests only allow for one-axis movement after each clamping. Changing the simulated flow direction requires removing the high-frequency ADCP, resetting its heading, and re-clamping it, a cumbersome operation. Consequently, in-depth research into these issues led to the development of this case. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: In conjunction with the specification Figure 1-6It can be seen that the purpose of this application is to solve the problems faced by the detection of flow velocity and flow direction of high-frequency ADCP (ADCP with a center frequency of not less than 1200kHz) in the factory process in a small water pool, such as the tedious and high cost of renting a large water pool for trailer testing and the difficulty of changing the flow direction with a traditional trailer. A simulation test device suitable for high-frequency ADCP is specifically designed, including a three-axis gantry 1 set above the test water pool, a mounting seat is set at the lower end of the Z axis of the three-axis gantry 1, and a height adjustment component is assembled and connected to the mounting seat. The height adjustment component moves A sliding seat 2 is provided at the end, a probe rod 3 is symmetrically installed on the sliding seat 2, a fixed seat 4 is provided at the lower end of the probe rod 3, a clamping limit assembly is provided on the fixed seat 4, a supporting member is assembled and connected at the lower end of the fixed seat 4, and a liquid level sensor 5 is installed at the lower end of the supporting member; wherein the clamping limit assembly includes a fixed groove 6, a drawing screw 7, a guide limiting member, two moving blocks 8 and a handwheel 9, the fixed groove 6 is installed on the fixed seat 4, the drawing screw 7 is rotatably set in the fixed groove 6, the guide limiting members are symmetrically arranged on both sides of the drawing screw 7, and the two moving blocks 8 are fixed with screw nuts 1 0, the screw nut 10 is threadedly matched with the drawing screw 7, the moving block 8 is connected to the moving end of the guide and limiting component, the handwheel 9 is fixed on the exposed end of the drawing screw 7, and the moving block 8 is assembled and connected with an arc clamping block 11. The above-mentioned guide and limiting component includes a guide rail 12 and a slider 13. The guide rail 12 is symmetrically arranged on both sides of the drawing screw 7. The slider 13 is slidably mounted on the guide rail 12 and connected to the moving block 8. When in use, the three-axis gantry 1 is set above the test pool, and the installation of the high-frequency ADCP to be tested is completed at the edge of the test pool. The high-frequency ADCP is vertically moved. The probe is placed in the direction of the center of the probe, and the detection end is stuck on the supporting member. The hand wheel 9 is turned to drive the drawing screw 7 to rotate. The drawing screw 7 rotates and then drives the moving blocks 8 on both sides to move toward each other under the common limiting cooperation of the screw nut 10, the guide rail 12 and the slider 13, so that the arc-shaped clamping block 11 on the moving block 8 is used to clamp and limit the high-frequency ADCP barrel. At this time, the lower end of the high-frequency ADCP is limited by the supporting member, and the two sides are limited by the arc-shaped clamping blocks 11, so that the fixing effect of the high-frequency ADCP can be effectively guaranteed. The installation is simple, the clamping effect is good, and it is easy to disassemble.After installation, the controller controls the X and Y axes to translate, coordinating the movement to move the high-frequency ADCP to the center of the test pool. The Z axis is then controlled to descend, bringing the high-frequency ADCP probe into contact with the water surface. The height adjustment assembly is further controlled to push the mounting base 4 downward, completely immersing the high-frequency ADCP probe in the water. The liquid level sensor 5 monitors the water depth from the support structure to the pool bottom, ensuring the high-frequency ADCP probe is fully immersed. The X and Y axes then coordinate horizontally to generate a predetermined velocity in a specific direction. Simultaneously, the high-frequency ADCP acquires relative water flow velocity data.

With its high level of integration, a single installation allows for simulation of flow velocities in multiple directions.

The outer ring surface of the dynamic support ring 20 is provided with an inverted stepped boss that matches the step structure, and the inner ring surface of the movable support ring 20 is a stepped structure. When in use, according to the different external dimensions of the high-frequency ADCP to be tested, the adaptability of the device can be improved by adding or reducing the corresponding model size of the reducing clamp 15 and the movable support ring 20, thereby further improving the practicality of the test. That is, when the actual external dimensions of the high-frequency ADCP to be tested are smaller than the dimensions shown in Figure A, the reducing clamp 15 and the movable support ring 20 of the corresponding model size can be selected to be installed in the arc clamp 11 and the fixed support ring 19; when the actual external dimensions of the high-frequency ADCP to be tested are larger than the external dimensions shown in Figure A, the current reducing clamp 15 and the movable support ring 20 can be removed.

[0022] During the specific implementation process, as a preferred setting, the above-mentioned height adjustment component includes a screw module 21, a guide column 22 and a sliding frame 23. The screw module 21 is arranged on the mounting seat in the vertical direction, and the guide columns 22 are symmetrically arranged on both sides of the screw module 21. The sliding frame 23 is installed on the moving end of the screw module 21 and slides with the guide column 22. The screw module 21 is used as a power source to realize the height adjustment of the sliding frame 23 in the vertical direction, thereby achieving synchronous control of the height of the sliding seat 2, the probe rod 3 and the fixed seat 4. The setting of the height adjustment component is to supplement the vertical downward threshold of the Z axis of the three-axis gantry 1 to avoid the high-frequency ADCP detection end to be tested from being completely immersed in water, affecting the accuracy of the test data.

[0023] It should be emphasized that the above-mentioned test water pool is preferably a small water pool of 5 meters square; the specific structure and selection of the three-axis gantry 1 can be found in the non-standard customized three-axis gantry 1 produced and sold by Weifang Yihe Intelligent Equipment Co., Ltd.; the ADCP tested is a high-frequency ADCP with a center frequency of not less than 1200kHz; the high-frequency ADCP obtains relative water flow velocity data which is collected by the host computer; the three-axis gantry 1, the screw module 21 and the liquid level sensor 5 are all connected to the controller through electrical signals.
