Description

Technical Field

[0001] This utility model relates to an ADCP fixing platform for an ultrasonic Doppler current measuring instrument, and more particularly to an ADCP fixing platform that automatically adjusts the draft. Background Technology

[0002] In existing hydrological measurement technologies, ADCP is a commonly used flow velocity measuring instrument. However, traditional fixed ADCP platforms have some problems: first, the draft of the ADCP cannot be automatically adjusted, and when the water level changes, the draft of the ADCP may be insufficient, leading to invalid measurement results; second, there is a lack of safety protection measures for the ADCP during underwater operation, making it easy to be damaged by collisions with the riverbed or other obstacles.

[0003] Therefore, it is necessary to develop a new ADCP fixing platform to overcome the problems of existing technologies. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the prior art, this utility model provides an ADCP fixed platform that automatically adjusts the draft, which can automatically adjust the draft and ensure operational safety, thus solving the problems of insufficient automatic adjustment of ADCP draft and inadequate operational safety in the prior art.

[0005] Technical Solution: This utility model discloses an ADCP fixing platform for automatically adjusting draft, characterized in that: it includes a dual-beam ADCP, which is mounted on an instrument mounting panel; the instrument mounting panel is mounted on a longitudinal lead screw and a longitudinal guide rail of a longitudinal moving panel, and the instrument mounting panel moves vertically on the longitudinal moving panel via a longitudinal servo motor and a longitudinal lead screw; the longitudinal moving panel is mounted on a transverse guide rail and a transverse lead screw of a transverse fixed panel, and the longitudinal moving panel moves horizontally on the transverse fixed panel via a transverse servo motor and a transverse lead screw; a pressure level gauge is provided on the upper surface of the dual-beam ADCP, and an ultrasonic depth sounder is provided on the lower surface of the dual-beam ADCP.

[0006] The dual-beam ADCP is fixedly connected to the instrument mounting panel by screws.

[0007] The pressure level gauge is connected to the controller of the longitudinal servo motor.

[0008] The ultrasonic depth sounder is connected to the controller of the horizontal servo motor.

[0009] The longitudinal servo motor is connected to the longitudinal lead screw.

[0010] The horizontal servo motor is connected to the horizontal lead screw.

[0011] The dual-beam ADCP is an ultrasonic Doppler flow velocity meter.

[0012] Working Principle: The pressure level gauge measures the draft of the ADCP in real time and transmits the data to the longitudinal servo motor controller. The controller compares the preset draft with the actual measured value. If a deviation exists, the controller adjusts the operation of the longitudinal servo motor, driving the instrument mounting panel up and down via the longitudinal lead screw and longitudinal guide rail until the set draft is reached. The ultrasonic depth sounder continuously monitors the distance between the ADCP and the riverbed bottom. When the distance is too close, it sends a signal to the transverse servo motor, causing it to drive the longitudinal moving panel horizontally along the transverse guide rail via the transverse lead screw, moving it away from the riverbed bottom to ensure equipment safety. The transverse servo motor can also periodically adjust the position of the longitudinal moving panel according to a preset measurement path or area, enabling switching between different measurement points and improving the measurement coverage.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention is applicable to the flow velocity measurement of water bodies such as rivers, lakes, and oceans. It uses a servo motor to control the draft of ADCP in real time, which can automatically adjust the draft and ensure safe operation, thus solving the problems of insufficient automatic adjustment of ADCP draft and inadequate operational safety in the prior art.

[0014] This invention offers the following advantages: 1. Automatic draft adjustment: Through the cooperation of a pressure-type water level gauge and a longitudinal servo motor, the draft of the ultrasonic depth sounder (ADCP) can be automatically adjusted in real time according to water level changes, ensuring the accuracy and validity of measurement results and avoiding measurement failures caused by water level fluctuations. 2. Enhanced operational safety: The ultrasonic depth sounder effectively monitors the distance between the ADCP and the riverbed bottom, preventing damage to the instrument due to excessive proximity to the riverbed, extending equipment lifespan, and reducing maintenance costs. 3. Improved measurement flexibility: The combination of a transverse servo motor and a transverse lead screw not only adjusts the equipment position when the water level changes but also allows movement along a preset path, enabling multi-point measurements, improving the comprehensiveness and representativeness of measurement data, and providing richer information for hydrological research. 4. Adaptability to various aquatic environments: The platform's reasonable structural design makes it suitable for rivers, lakes, oceans, and other water bodies with different depths and terrains, exhibiting wide applicability and versatility to meet diverse measurement needs.

The longitudinal moving panel 3 is mounted on a transverse guide rail 5 and a transverse lead screw 8 of a transverse fixed panel 12. The longitudinal moving panel 3 is driven by a transverse servo motor 7 and the transverse lead screw 8 to move horizontally on the transverse fixed panel 12. A pressure level gauge 6 is provided on the upper surface of the dual-beam ADCP4 to measure the instrument's draft and provide feedback to the longitudinal servo motor controller for timely adjustment of the instrument's draft. An ultrasonic depth sounder 9 is provided on the lower surface of the dual-beam ADCP4 to measure the distance between the instrument and the riverbed bottom, ensuring the safety of the equipment during operation. The dual-beam ADCP4 is fixedly connected to the instrument mounting panel 1 by screws. The pressure level gauge 6 is connected to the controller of the longitudinal servo motor 2.

[0021] This utility model includes the following components:

[0022] Instrument Mounting Panel 1: Used for mounting dual-beam ADCP and other optional instruments, secured with screws. This panel is designed to ensure instrument stability while facilitating disassembly and maintenance.

[0023] Longitudinal servo motor 2: Connected to the longitudinal lead screw, it drives the instrument mounting panel to move vertically along the longitudinal guide rail, thereby precisely adjusting the draft of the ADCP. The control precision of the motor directly affects the accuracy of the ADCP draft adjustment.

[0024] Longitudinal Movement Panel 3: Connected to the instrument mounting panel, it can move horizontally along the transverse guide rail and transverse lead screw. The range of motion of this panel should meet the needs of different measurement areas.

[0025] Dual-beam ADCP4: Mounted on the instrument's mounting panel, it is used to measure water flow velocity. Its design should provide high-precision flow velocity measurement capabilities and adapt to the measurement needs of different water bodies.

[0026] Horizontal guide rail 5: Provides a horizontal track for the vertically moving panel, ensuring smooth and accurate movement.

[0027] Pressure-type water level gauge 6: Mounted on the upper surface of the dual-beam ADCP, it is used to measure the instrument's draft in real time and feed the data back to the longitudinal servo motor controller. Its measurement accuracy should meet the requirements for draft adjustment.

[0028] Horizontal servo motor 7: Connected to the horizontal lead screw, it drives the horizontal lead screw to move the vertical moving panel horizontally. The control precision of the motor determines the accuracy of the horizontal movement distance of the vertical moving panel.

[0029] Horizontal lead screw 8: Works with the horizontal servo motor to achieve horizontal movement of the vertical moving panel. The accuracy of the lead screw directly affects the accuracy of the vertical moving panel's position.

[0030] Ultrasonic depth sounder 9: Mounted on the lower surface of the dual-beam ADCP, it is used to measure the distance between the instrument and the riverbed bottom, ensuring safe operation of the equipment. Its measurement accuracy should meet the requirements for safe operation.

[0031] Longitudinal lead screw 10: Works in conjunction with a longitudinal servo motor to enable vertical movement of the instrument mounting panel. The accuracy of the lead screw directly affects the accuracy of the instrument mounting panel's movement position.

[0032] Longitudinal guide rail 11: Provides a vertical track for the instrument mounting panel, ensuring smooth and accurate movement.

[0033] Horizontal fixed panel 12: Serves as the base of the entire platform and mounts other components. Its design should ensure the stability and load-bearing capacity of the entire platform.

[0034] In operation, first, fix the horizontal mounting panel in a suitable position within the measurement area, such as a fixed stake perpendicular to the water surface on one side of the river. Install the dual-beam ADCP on the instrument mounting panel and connect the lines to the pressure level gauge and ultrasonic depth sounder. After starting the equipment, the pressure level gauge begins real-time monitoring of the ADCP's draft. If the water level drops, resulting in insufficient draft, the longitudinal servo motor receives a controller command and drives the instrument mounting panel downwards along the longitudinal guide rail and longitudinal lead screw, increasing the draft to the set value. Conversely, if the water level rises, the motor drives the panel upwards, reducing the draft and maintaining measurement validity. Simultaneously, the ultrasonic depth sounder continuously probes the distance between the ADCP and the riverbed bottom. Once the distance falls below a safety threshold, the horizontal servo motor immediately activates, pushing the longitudinal moving panel horizontally along the horizontal guide rail via the horizontal lead screw, moving the ADCP away from the riverbed bottom to avoid collision. During long-term monitoring, the horizontal servo motor can periodically adjust the ADCP's horizontal position according to a preset measurement plan, enabling the acquisition of flow velocity data at different measurement sections and providing more comprehensive and accurate data for hydrological analysis.

[0035] This invention offers the following advantages: 1. Automatic draft adjustment: Through the cooperation of a pressure-type water level gauge and a longitudinal servo motor, the draft of the ultrasonic depth sounder (ADCP) can be automatically adjusted in real time according to water level changes, ensuring the accuracy and validity of measurement results and avoiding measurement failures caused by water level fluctuations. 2. Enhanced operational safety: The ultrasonic depth sounder effectively monitors the distance between the ADCP and the riverbed bottom, preventing damage to the instrument due to excessive proximity to the riverbed, extending equipment lifespan, and reducing maintenance costs. 3. Improved measurement flexibility: The combination of a transverse servo motor and a transverse lead screw not only adjusts the equipment position when the water level changes but also allows movement along a preset path, enabling multi-point measurements, improving the comprehensiveness and representativeness of measurement data, and providing richer information for hydrological research. 4. Adaptability to various aquatic environments: The platform's reasonable structural design makes it suitable for rivers, lakes, oceans, and other water bodies with different depths and terrains, exhibiting wide applicability and versatility to meet diverse measurement needs.
