Description

Technical Field

[0001] The utility model relates to the technical field of flow measuring instruments, in particular to a high-stability ADCP flow measuring instrument. Background Art

[0002] ADCP current meter is an advanced velocity measuring sonar device that integrates multidisciplinary technologies such as hydroacoustic physics, hydroacoustic transducer design, electronic technology and signal processing.

[0003] The ADCP current meter uses the acoustic Doppler principle to determine the speed and direction of water flow by measuring the propagation time and frequency changes of sound waves in water. Specifically, it emits sound wave pulses, which propagate in the water and scatter from particles or bubbles in the water. The receiver receives the scattered sound waves and measures the frequency changes of the sound waves. According to the principle of the Doppler effect, the frequency of the sound waves will change when the water flow is in the same or opposite direction as the propagation of the sound waves; when the water flow is perpendicular to the propagation direction of the sound waves, the frequency of the sound waves will not change. ADCP determines the speed and direction of water flow by measuring the frequency changes of sound waves.

[0004] The existing high-stability ADCP current measuring instrument is not convenient to be installed on the measuring rod, and the single-point sensor cannot be rotated to different angles to expand the detection range of the water area, and has poor practicality. Utility Model Content

The single-point sensor can be rotated to different angles to expand the detection range of the water area. It has strong practicality and good stability and is suitable for wide promotion.

[0006] The technical solution adopted by the utility model to solve the technical problem is a high-stability ADCP flow meter, comprising a U-shaped bracket, a positioning ring, a single-point sensor and a host, locking bolts are installed at both ends of the positioning ring through screw holes, one end of the locking bolt is connected to the U-shaped clamping plate through a bearing B, the two sides of the positioning ring are connected to the U-shaped bracket through rivets, a servo motor is installed on one side of the U-shaped bracket through a mounting seat, and the output shaft of the servo motor is connected to the rotating shaft through a coupling;

[0007] The top of the rotating shaft is connected to the support plate through a connecting plate, L-shaped limit plates are arranged on both sides of the top of the support plate and a single point sensor is arranged between the L-shaped limit plates, a host limit sleeve is installed on the top of the U-shaped bracket through bolts and the host is arranged inside the host limit sleeve.

[0008] By adopting the above technical solution, the ADCP current meter is easy to install on the measuring rod, and the single-point sensor can be rotated to different angles to expand the detection range of the water area. It has strong practicality and good stability and is suitable for wide promotion.

[0009] Specifically, a servo motor controller is mounted on the lower end of the servo motor via screws, and an output end of the servo motor controller is electrically connected to an input end of the servo motor via a wire.

[0010] By adopting the above technical solution, the rotation angle of the servo motor is automatically controlled by using the servo motor controller, so that the single-point sensor can be rotated to different angles.

[0011] Specifically, the L-shaped limiting plate and the host limiting sleeve are both made of PU material.

[0012] Specifically, both ends of the rotating shaft are sleeved between U-shaped brackets through bearings A, and the host is connected to the single-point sensor through a wire.

[0013] By adopting the above technical solution, the single-point sensor emits sound wave pulses, which propagate in the water and scatter with particles or bubbles in the water. The receiver receives the scattered sound waves and measures the frequency changes of the sound waves, thereby measuring the flow rate and direction and displaying them through the host.

[0014] Specifically, a power storage box is installed on the upper end of the servo motor by screws, and the output end of the power storage box is electrically connected to the servo motor, the single-point sensor and the input end of the host by wires.
