Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acoustic Doppler flow profiler assembly, in particular to a split transducer array locking and flipping device of an acoustic Doppler flow profiler. Background Art
[0002] The acoustic Doppler current profiler uses the acoustic Doppler effect to measure flow. The transducer array on the device is both a transmitter and a receiver, emitting sound wave pulses of a certain frequency. When these pulses hit scattering objects (such as suspended matter) in the water, an echo signal is generated. Since the suspended matter will drift with the water flow, there will be a frequency difference between the frequency of the echo signal and the frequency of the transmitted signal. By measuring this frequency difference, the flow velocity at the corresponding point can be obtained. The split transducer array of the acoustic Doppler current profiler is composed of multiple transducers, which can provide a larger detection range and stronger target positioning capability. At the same time, the transducer array can achieve beamforming by changing the working state of different transducers, thereby further improving the resolution of detection and imaging. During the assembly process of the split transducer array, the entire transducer array needs to be flipped to complete all assembly work; in the prior art, facing the heavy split transducer array, it is necessary to lift it by two people to achieve flipping and station transfer, which is labor-intensive. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case. Utility Model Content

[0021] Embodiment: In conjunction with the specification Figure 1-10 It can be seen that in order to solve the problem in the prior art that the heavy split transducer array 13 needs to be lifted by two people to achieve flipping and station transfer, which is inconvenient to operate and has high labor intensity, the present application specifically designs a split transducer array 13 locking and flipping device for an acoustic Doppler flow profiler, comprising a workbench 1 and a liftable bracket 2, the liftable bracket 2 is arranged on the workbench 1, one end of the liftable bracket 2 is rotatably mounted with a vertical shaft 3, the middle position of the vertical shaft 3 is equipped with a horizontal shaft 4 in a horizontal posture, the horizontal shaft 4 is fixedly connected to the crossbeam 5 through a support, an elastic top pin 12 is installed on the side of the support, the side wall of the vertical shaft 3 is symmetrically provided with pits along the axial position of the horizontal shaft 4, the size of the pit matches the elastic top pin 12, one end of the crossbeam 5 is equipped with an expansion member and a quick-retractable clamp 6, the expansion member is used to clamp the split transducer array 13, see the attached Figure 1 -Attached Figure 4When in use, the crossbeam 5 is rotated out of the workbench 1, and the split transducer array 13 is limitedly locked by using the quick-retractable clamp 6 in cooperation with the expansion member, so as to lock the split transducer array 13 in a locked state, so as to facilitate the assembly operation on the upper surface of the split transducer array 13; see the attached Figure 5 And attached Figure 6 After the upper surface assembly of the split transducer array 13 is completed, a force is applied to one side of the split transducer array 13 to rotate the split transducer array 13 as a whole along the horizontal axis 4 by 180°, and the split transducer array 13 is further pushed to move it onto the workbench 1, and the expansion member is driven by the fast telescopic clamp 6 to release the split transducer array 13; see the attached Figure 7 And attached Figure 8 , adjust the height of the bracket 2 to drive the crossbeam 5 to rise as a whole. When the expansion core 10 is higher than the split transducer array 13, push the crossbeam 5 to rotate around the vertical axis 3 to the outside of the workbench 1, and then perform subsequent assembly work on the split transducer array 13; in the face of the heavy split transducer array 13, operating both sides of the split transducer array 13 on the device can avoid the need for two people to lift it to achieve flipping and station transfer, and no additional power source is required. Moreover, flipping only requires a small force, which saves one operator and reduces the labor intensity of the workers.
[0022] In the specific implementation process, as a preferred setting, the above-mentioned tensioning member includes two thrust bearings 7 arranged at one end of the crossbeam 5, a core shaft 9 is installed in the thrust bearing 7, the lower end of the core shaft 9 is connected to the quick telescopic clamp 6, and an expansion core 10 is installed on the telescopic rod of the quick telescopic clamp 6, and an expansion sleeve 11 is sleeved on the outer end of the expansion core 10; wherein the step at the upper end of the above-mentioned core shaft 9 cooperates with the upper thrust bearing 7 to prevent the downward axial movement of the core shaft 9, and the lower end of the core shaft 9 is fixed with a nut 8 and cooperates with the lower thrust bearing 7 to limit the upward axial movement of the core shaft 9.
[0023] The power source of the liftable bracket 2 is a hydraulic cylinder, a pneumatic cylinder or an electric push rod.
[0024] It should be pointed out that the selection and structure of the split transducer array 13 is a four-beam transducer, which is mainly used to transmit and receive acoustic signals. Four sets of transducer units and a variety of sensors are integrated thereon. Since it is a low-frequency acoustic Doppler flow profiler, the weight of a single transducer is heavy. If it is processed as a whole, the cost of raw materials and the difficulty of processing will increase. The split design is simple. Since a single element of the split transducer array is heavy, it is not suitable for single-person operation, so tooling is required for auxiliary assembly. For the specific structure, see Fig. 9 as well as Fig.10 shown.
[0025] The working principle is as follows: a liftable bracket 2 is installed on the workbench 1 for connecting the vertical shaft 3. The liftable bracket 2 can be lifted upward, and the vertical shaft 3 can rotate along its axis in the liftable bracket 2. A horizontal shaft 4 is installed in the middle of the vertical shaft 3. At the same time, a pit is provided on the upper and lower outer circumferential surfaces of the vertical shaft 3 on which the horizontal shaft 4 is installed; a crossbeam 5 is connected to the horizontal shaft 4 through a support, and the crossbeam 5 can rotate horizontally around the horizontal shaft 4. The elastic top pin 12 on the support can just be pushed into the pit of the vertical shaft 3, so as to realize that the crossbeam 5 is kept in the upper and lower positions around the horizontal shaft 4. When the force of the rotating crossbeam 5 breaks through the elastic force of the elastic ejector pin 12, the position holding state of the crossbeam 5 can be destroyed to realize the horizontal rotation of the crossbeam 5; two thrust bearings 7 are installed at the other end of the crossbeam 5, and the core shaft 9 is installed in the thrust bearing 7. The downward axial movement of the core shaft 9 is prevented by the step of the core shaft 9, and the upward axial movement of the core shaft 9 is limited by a nut 8 and another thrust bearing 7 at the other end of the core shaft 9; a quick telescopic clamp 6 is installed at the lower part of the core shaft 9, and an expansion core 10 is installed on the telescopic rod of the quick telescopic clamp 6, and an expansion sleeve 11 is sleeved on the outer end of the expansion core 10, and the core shaft 9 can limit the downward movement of the expansion sleeve 11.
[0026] When in use, the crossbeam 5 is rotated outward from the workbench 1, and the expansion core 10 connected to the quick-expanding clamp 6 is kept in an extended state. The central circular hole of the base of the split transducer array 13 of the acoustic Doppler flow profiler is aligned with the expansion sleeve 11 and dropped until the base contacts the end face of the core shaft 9; the quick-expanding clamp 6 is pulled downward to drive the expansion core 10 to retract, and the conical contact between the expansion core 10 and the expansion sleeve 11 forces the outer surface of the upper end of the expansion sleeve 11 to expand until the central circular hole of the base of the split transducer array 13 is locked. At the same time, the quick-expanding clamp 6 reaches a self-locking state, thereby maintaining the state of locking the split transducer array 13.
[0027] After completing the upper surface assembly work of the split transducer array 13, force is applied to the split transducer array 13 to rotate the whole along the horizontal axis 4. When the front end of the elastic push pin 12 enters the upper pit of the vertical axis 3, a new position is formed. Since the overall center of gravity of the rotating part coincides with the horizontal axis 4, the rotation process is relatively labor-saving; the split transducer array 13 is pushed to move it to the workbench 1, so that the quick-retractable clamp 6 drives the expansion core 10 to extend, and the outer surface of the expansion sleeve 11 contracts after the expansion core 10 is out of contact to release the split transducer array 13, and then the bracket 2 drives the crossbeam 5 to rise as a whole. When the expansion core 10 is higher than the split transducer array 13, the crossbeam 5 is pushed to rotate around the vertical axis 3 to the outside of the workbench 1, and then the split transducer array 13 is subsequently assembled.
[0028] To sum up, in the face of the heavy split transducer array 13, operating both sides of the split transducer array 13 on the device can avoid the need for two people to lift it to achieve flipping and workstation transfer, does not require additional power source assistance, and only requires a small force for flipping, saving one operator and reducing the worker's labor intensity.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
