Description

Transducer array replaceable five-beam ADCP
Technical Field
The invention relates to a transducer array replaceable five-beam ADCP, and belongs to the field of applied acoustics.
Background
An Acoustic Doppler Current Profiler (ADCP) is an advanced real-time measuring device for Current flow rate and flow rate in the world. By using the acoustic Doppler principle, the ADCP emits acoustic pulses to the water body, the acoustic pulses generate reflected waves after encountering particles which are suspended in the water body and move along with the water body, the ADCP receives the reflected waves and records the frequency change between the reflected waves and the emitted waves, and the frequency change is Doppler frequency shift, so that the water flow velocity is calculated. The working modes of the ADCP mainly include: ship-borne sailing type, ship-borne towing type, underwater self-contained type and shore-based direct reading type. The shipborne sailing type ADCP is widely applied to the fields of oceans, lakes, rivers and the like, and is generally divided into a phased array ADCP and a non-phased array ADCP. Phased arrays ADCP are more applied to the low-frequency field, and the array is generally integrally vulcanized and poured. Common home and abroad non-phased array ADCP generally independently pours and vulcanizes 4 transducer arrays onto a base, the planes of the 4 transducer arrays form an included angle of about 20 degrees with the horizontal plane, and a wave beam obliquely faces downwards in four directions. In the process of pouring and vulcanizing 4 independent transducer arrays, 4 array performances are easy to be inconsistent in the traditional non-phased array ADCP, and the impedance difference is large, so that the performance index of the complete ADCP is reduced. In the production process, as the filling vulcanization process basically has no maintainability, the performance indexes of 1 transducer array are unqualified in the filling vulcanization process, and the rest 3 transducer arrays can not be used, so that the production and manufacturing cost is increased, the yield is reduced, and the resource waste is also caused. The manufacturing method of integrally pouring and vulcanizing the transducer array to the base also results in poor versatility and adaptability of the transducer array with different frequencies, and if a non-phased array ADCP with different frequencies is used, the transducer array and the vulcanized base need to be redesigned and manufactured. When the traditional non-phased array ADCP needs to measure the depth information of the paired bases, the ADCP is generally set to be a speed measurement mode of the paired bases, the speed measurement mode is obtained through conversion of four oblique downward wave beam measurement information, and the precision of the measured depth information is low.

Detailed Description
The invention will be further elucidated and described with reference to the drawings and the detailed description. The technical features of the embodiments of the present invention can be combined correspondingly without mutual conflict.
As shown in fig. 1, fig. 2 and fig. 7, the transducer array replaceable five-beam ADCP in an embodiment of the present invention mainly includes an electronic cabin 1, an electronic cabin end cover 2, a transducer base 3, four flow velocity measurement probes 4, a depth measurement probe 5, a temperature and pressure sensor 6, a temperature and pressure sensor cover 7, an attitude sensor assembly 8, a watertight connector 9, and a watertight connector plug 10. The invention adds a depth measuring probe 5 on the basis of the traditional four flow velocity measuring probes 4. The four flow velocity measurement probes can measure water flow velocity information by using an acoustic Doppler principle, the depth measurement probe can provide fifth vertical beam information for ADCP measurement by using the acoustic Doppler principle, and more accurate water depth data is provided for shipborne sailing measurement. The specific form of the flow rate measuring probe 4 and the depth measuring probe 5 is not limited, and any device capable of achieving this function may be used. In the present embodiment, the flow velocity measurement probe 4 and the depth measurement probe 5 are preferably measured using a non-phased transducer array. Certainly, the non-phased transducer array needs to be matched with necessary circuit boards for signal transceiving, processing and the like, and these electronic devices such as the PCB board and the like can be placed in the inner cavity of the electronic cabin 1. According to the invention, the flow velocity measuring probe 4 and the depth measuring probe 5 can be detached and replaced through screws on the back of the probes, and the flow measuring performance of the ADCP complete machine is improved by detecting and screening the measuring probes with better consistency in advance. The replaceable design of the measuring probe can also effectively reduce the design and manufacturing cost and the maintenance cost of the ADCP complete machine, and can improve the universality and the replaceability of the measuring probes with different frequencies. The specific structure of each part and its operation principle are described in detail below.
As shown in fig. 2, the electronic cabin 1 is a hollow cylinder, and the top flange ring and the bottom flange ring are provided with screw mounting holes, and various electronic devices and cables can be accommodated inside the screw mounting holes. In order to ensure the airtightness of the inner cavity of the electronic cabin 1, the electronic cabin end cover 2 is mounted at the top of the electronic cabin 1 through screws, the transducer base 3 is mounted at the bottom of the electronic cabin 1 through screws, and first waterproof sealing parts are arranged between the electronic cabin 1 and the electronic cabin end cover 2 and between the electronic cabin 1 and the transducer base 3, so that water vapor is prevented from entering the inner cavity of the electronic cabin 1, and the form of the waterproof sealing parts is not limited. In this embodiment, the electronic capsule 1 and the electronic capsule end cover 2, and the electronic capsule 1 and the transducer base 3 are sealed by the third O-ring 22 through right-angle grooves. In addition, in consideration of the transmission requirements of power supply and signals, the transmission between the inside and the outside of the cabin body needs to be realized through watertight connectors. Thus, a watertight connector 9 is fixed to the top of the electronics compartment end cap 2. The internal terminal of the watertight connector 9 is communicated with the inner cavity of the electronic cabin 1, and the external terminal is sealed by a watertight connector plug 10. A matched watertight connector plug 10 can be installed under the condition that an external watertight cable is not connected, so that water is prevented from entering or being blocked, and the plug can be pulled out when in use.
As shown in fig. 2 and 5, in order to prevent the watertight connector 9 from loosening and leaking water during high-speed sailing, a boss enclosure 26 is disposed on the top of the electronic cabin end cap 2 and symmetrically arranged in an inverted "u" shape, so as to limit and fix the installation direction of the watertight connector 9. A second heading arrow 27 is etched into the front of the raised perimeter 26 to help the user of the apparatus discern the heading of the ADCP. An attitude sensor assembly mounting boss 31 is arranged on the inner side of the electronic cabin end cover 2, and a screw hole is formed in the boss. The attitude sensor assembly 8 is mounted on the attitude sensor assembly mounting boss 31 by screws. In addition, in this embodiment, six second U-shaped counter bores 28, four through-connection mounting through holes 29 and three cover-opening screw holes 30 are circumferentially and uniformly arranged on a boss on the periphery of the top of the electronic cabin end cover 2. And the bottom of the second U-shaped counter bore 28 is provided with a screw mounting through hole respectively for mounting a fastening screw between the electronic cabin 1 and the electronic cabin end cover 2. The same number of screw holes are provided at the top end of the electronic compartment 1 corresponding to the positions of the through holes 29 for docking the ADCP with the external mounting structure in this embodiment. The cover-opening screw hole 30 is used for ejecting the electronic cabin end cover 2 tightly matched with the electronic cabin 1 out of the matching surface without damaging the appearance and the structure by screwing in the screw when the electronic cabin end cover 2 of the ADCP is detached. The number and arrangement of the second U-shaped counter bore 28, the connecting and mounting through holes 29 and the cap-opening screw holes 30 are not limited.
As shown in fig. 3 and 4, the outer bottom of the transducer base 3 is provided with 4 flow velocity measurement probe mounting holes 14 which are uniformly arranged in the circumferential direction, the four flow velocity measurement probes 4 are arranged in the flow velocity measurement probe mounting holes 14 of the transducer base 3 in the circumferential direction, the central axis of the measurement beam and the central axis of the hollow cylinder of the ADCP electronic cabin 1 are all in the same slope angle, and the slope surface of the measurement beam is gradually reduced towards the side edge by taking the central axis of the ADCP electronic cabin 1 as the vertex. The depth measuring probe 5 is vertically installed in a depth measuring probe installation hole 15 at the bottom of the transducer base 3. Screw holes and second waterproof sealing pieces which are annularly arranged are arranged on back mounting surfaces of the flow velocity measuring probe 4 and the depth measuring probe 5, and the waterproof sealing pieces are not limited in form but need to be larger than the center distance of the screw holes in size. In the present embodiment, the back of the flow rate measurement probe 4 is sealed with a rectangular groove by the second O-ring, and the depth measurement probe 5 is sealed with a rectangular groove by the first O-ring 20. The number and the arrangement mode of the screw holes are all corresponding to the through holes on the circular screw mounting plane 16 on the inner wall of the transducer base 3. The fixing screws of the flow velocity measuring probe 4 and the depth measuring probe 5 are fixedly arranged outwards from the inner wall of the transducer base 3. The round screw mounting plane 16 is arranged to provide a screw mounting plane on the concave spherical surface of the inner wall of the transducer base 3, so that the screw mounting and screwing are facilitated. And wire outlet holes for the routing of the flow velocity measuring probe 4 and the depth measuring probe 5 are formed in the inner sides of the circular screw mounting planes 16.
As shown in fig. 4, 6 and 7, since the ADCP also needs to measure the current water temperature and water pressure, a temperature and pressure sensor mounting hole 17 perpendicular to the inner wall is formed on the concave spherical surface of the inner wall of the transducer base 3 for mounting the temperature and pressure sensor 6. At least one vent hole 18 is arranged at the bottom of the temperature and pressure sensor mounting hole 17 and communicated with the outer side of the transducer base 3, so that the sensing energy of the temperature and pressure sensor can contact external fluid. The periphery of the temperature and pressure sensor mounting hole 17 is provided with 1 temperature and pressure sensor sealing cover mounting plane 19 and is provided with a plurality of screw holes. The shape and the arrangement of the screw holes are matched with the shape of the temperature and pressure sensor cover 7 shown in figure 6. The temperature and pressure sensor sealing cover 7 is used for limiting and fixing the temperature and pressure sensor 6, a round temperature and pressure sensor 6 wire outlet hole is formed in the middle of the temperature and pressure sensor sealing cover, and the temperature and pressure sensor sealing cover is installed on the inner wall of the energy converter base 3 through screws. Wherein, the temperature and pressure sensor 6 is of a watertight structure and is provided with a waterproof sealing element. An annular boss is arranged at the top of the transducer base 3, a plurality of screw holes are arranged on the boss and used for mounting electronic devices such as an internal PCB, and the form of the boss is not limited, so that the details are not repeated. A transducer base mounting plane 23 is provided at the bottom of the transducer base 3 at a position of the gap of the flow rate measurement probe mounting hole 14. The edge shape of the sensor is similar to the projection shape of the 4 flow rate measurement probe mounting holes on the transducer base mounting plane 23 and is slightly larger than the projection shape. Transition fillets are arranged at the connecting edges of the transducer base mounting plane 23 and the 4 flow rate measurement probe mounting holes 14, so that the fluid resistance of the ADCP in the process of use during sailing is reduced, and cavitation bubbles are prevented. In the present embodiment, the vent hole 18 of the warm-pressure sensor 6 is vertically arranged on the transducer base mounting plane 23, i.e., communicates internally to the warm-pressure sensor mounting hole 17. The transducer base mounting plane 23 is etched with a first heading arrow mark 25, and is located on the same side of the vent hole 18, so that water flow on the upstream side can enter the vent hole 18 in the process of heading navigation of the ADCP. The transducer base mounting plane 23 is provided with first U-shaped counter bores 24 arranged in a circumferential direction, and the bottom of the transducer base mounting plane is provided with screw mounting through holes for mounting fastening screws between the transducer base 3 and the electronic cabin 1, wherein the number of the first U-shaped counter bores 24 is not limited, and 4 groups of the first U-shaped counter bores are arranged in the circumferential direction in the embodiment.
As shown in fig. 8, since the ADCP also needs attitude and heading angle information of the ADCP in the cruising operation state, an attitude sensor assembly 8 including an attitude sensor 11, an attitude sensor shield case 12, and an attitude sensor shield cover 13 is mounted on the inner side of the electronic cabin end cover 2. The attitude sensor shielding box 12 is a hollow box structure, and is mounted on the attitude sensor assembly mounting boss 31 as a mounting base of the attitude sensor 11 by screws. The attitude sensor 11 is mounted in the inner cavity of the attitude sensor shield case 12, and the top is enclosed by an attitude sensor shield cover 13. In this embodiment, the attitude sensor shielding box 12 and the attitude sensor shielding cover 13 are both made of aluminum alloy, and play a role in protecting and shielding the attitude sensor 11 from electromagnetic signal interference.
In the five-beam ADCP of the invention, 4 flow velocity measurement probes are used for measuring the flow velocity profile, and the depth measurement probe is used for measuring the vertical depth of the water bottom. Compared with the depth information of the ground pair obtained in the four-beam ground speed measurement mode, the vertical beam depth measurement has higher precision and better performance. Compared with the traditional vulcanized ADCP array probe, the invention breaks through the irreplaceable limitation of the traditional non-phased ADCP when the consistency of the 4 flow rate measurement probes is poor, and the 5 probes can be detached and replaced under the condition of ensuring the sealing performance through structural optimization. Therefore, the invention can realize better impedance consistency of each flow velocity measuring probe by screening and replacing the probe, and can improve the adaptability of probes with different performances and different frequencies by replacing the probe, thereby greatly reducing the design and manufacturing cost and the maintenance cost of the transducer probe integrally vulcanized by the traditional ADCP. The depth measurement probe carried by the invention can provide fifth vertical beam information for ADCP, provide more accurate water depth data for shipborne sailing type measurement, and provide a technical approach for system development turbulence measurement and wave measurement.
The above-described embodiments are merely preferred embodiments of the present invention, which should not be construed as limiting the invention. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, the technical scheme obtained by adopting the mode of equivalent replacement or equivalent transformation is within the protection scope of the invention.
