Description

Technical Field

[0001] This utility model belongs to the field of hydrological measurement technology, specifically relating to an online hydrological flow monitoring vessel. Background Technology

[0002] Hydrological flow measurement is an important component of hydrological work, and it is of great significance for water resource management, flood control and disaster reduction, and engineering construction. ADCP (Doppler Ultrasonic Velocimetry), a flow measurement instrument based on the Doppler effect, obtains flow velocity profile data by emitting sound waves and analyzing the frequency shift of the reflected signals from suspended particles in the water. It uses bottom-tracking functionality to calibrate the instrument, combines this with water level data to calculate the cross-sectional area of ​​the water passage, and finally outputs the flow rate results.

[0003] Currently, mobile ADCPs are typically towed by inflatable boats, drones, or automated testing platforms. Regardless of the towing method, conducting tests in waterways carries the risk of the instrument becoming entangled in vegetation and being damaged by collisions. Utility Model Content

[0004] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a hydrological flow online monitoring vessel that is easy to operate, can effectively protect the instrument from damage, has high safety, and provides high accuracy in measurement data.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hydrological flow online monitoring vessel, including a hull, a driving engine located in the middle of the stern, a bridge located in the front of the hull, a generator and a battery located on the left side of the stern, a fuel tank located on the right side of the stern, two measuring vertical cylinders arranged forward and backward below the bridge on the hull, the lower end of the measuring vertical cylinders being open and flush with the bottom of the hull, a Doppler ultrasonic velocimeter located in one measuring vertical cylinder, a dual-frequency depth sounder located in the other measuring vertical cylinder, and a towed measuring device located on the side of the hull.

[0006] Each measuring cylinder has an annular plate on its outer circumference at the upper port. An annular rubber pad is placed on the annular plate, and a cover plate is placed on the annular rubber pad to close the upper port of the measuring cylinder. A connecting ear plate is placed on the outer circumference of the measuring cylinder below the annular plate. A fastening bolt is placed on the connecting ear plate. The fastening bolt passes through the annular plate, the annular rubber pad and the cover plate from bottom to top and is threaded with a wing nut. The lower end of the wing nut is pressed against the top surface of the cover plate.

[0007] A perforation is provided at the center of the cover plate, and a fixed tube with the same center line as the measuring vertical cylinder is provided on the top surface of the cover plate. Several first connecting holes are evenly spaced along the length of the fixed tube. An instrument connecting rod is inserted into the fixed tube. A second connecting hole corresponding to one or two of the first connecting holes is provided on the instrument connecting rod. The first connecting holes and the second connecting holes are connected by a horizontally inserted bolt assembly. The lower end of the instrument connecting rod extends into the measuring vertical cylinder. The top of the Doppler ultrasonic velocimeter or dual-frequency depth sounder is fixedly connected to the lower end of the instrument connecting rod.

[0008] The towed measuring device includes a DC motor, a worm gear reducer, and a tow bar. The DC motor and the worm gear reducer are fixedly mounted on the port front side of the hull. The main shaft of the DC motor is connected to the input shaft of the worm gear reducer. The output shaft of the worm gear reducer is vertically upward and connected to the front end of the tow bar. The rear end of the tow bar is connected to a traveling ADCP.

[0009] By adopting the above technical solution, compared with the prior art, this utility model has the following technical effects: 1) The control panel in the driver's cab is equipped with a positioning device that can record the vessel's trajectory in real time to verify whether the reciprocating trajectory is consistent during the test. The connecting rod is a hollow tube, with data signal lines connected to the instruments passing through its interior. These data signal lines are then connected to the driver's cab.

[0010] 2) The hull of this online monitoring vessel is made of aluminum alloy. This ensures both hull strength and lightweight construction. It effectively reduces the vessel's draft, ensuring the smooth operation of the testing work, and is particularly suitable for shallow waterways like the Yellow River.

[0011] 3) This utility model features two measuring cylinders, each housing a Doppler ultrasonic velocimeter (ADCP probe) and a dual-frequency depth sounder. The lower ends of the measuring cylinders are open, allowing river water to enter. This completely prevents entanglement with grass or collisions during measurement. The instrument height can be adjusted via the height of the instrument connecting rod. Adjustment is achieved by connecting the second connecting hole on the instrument connecting rod to the first connecting holes at different heights. A cover plate not only provides a suspension connection point for the instrument connecting rod but also seals the upper end of the measuring cylinder, preventing river water from entering the cab.

[0012] 4) This utility model can also suspend the ADCP at the rear end of the tow bar, and control the DC motor switch from the cab. The DC motor drives the tow bar to rotate horizontally by 90° through the worm gear reducer. When the DC motor switch is turned off, the worm gear reducer has a self-locking function. The ADCP suspended at the rear end of the tow bar can carry out hydrological tests as the ship moves. When encountering aquatic plants or trees in the river, the DC motor switch can be started in advance to drive the tow bar to rotate backward onto the ship. After passing the aquatic plants or trees, it can be unfolded for measurement, thereby avoiding damage to the instrument.

[0013] In summary, this utility model, by setting a concealed measuring vertical cylinder inside the hull and a rotating towed measuring structure outside the hull, allows for simultaneous use during measurement, facilitating comparison of the measurement results from the two methods and enabling the selection of the more accurate one. Furthermore, it allows for the selection of a measurement method based on the actual conditions of the river channel, resulting in more diverse measurement methods while ensuring the safety and reliability of the measuring instruments.

A cover plate 11 is provided on the annular rubber pad 10 to close the upper port of the measuring vertical cylinder 6. A connecting ear plate 12 is provided on the outer circumference of the measuring vertical cylinder 6 below the annular plate 9. A fastening bolt 13 is provided on the connecting ear plate 12. The fastening bolt 13 passes through the annular plate 9, the annular rubber pad 10 and the cover plate 11 from bottom to top and is threaded to a wing nut 14. The lower end of the wing nut 14 is pressed against the top surface of the cover plate 11.

[0018] A through hole is provided at the center of the cover plate 11. A fixed tube 15 with the same center line as the measuring vertical cylinder 6 is provided on the top surface of the cover plate 11. Several first connecting holes 16 are evenly spaced along the length of the fixed tube 15. An instrument connecting rod 17 is inserted into the fixed tube 15. A second connecting hole corresponding to one or two of the first connecting holes 16 is provided on the instrument connecting rod 17. The first connecting holes 16 and the second connecting holes are connected by a horizontally inserted bolt assembly 18. The lower end of the instrument connecting rod 17 extends into the measuring vertical cylinder 6. The top of the Doppler ultrasonic velocimeter 7 or the dual-frequency depth sounder 8 is fixedly connected to the lower end of the instrument connecting rod 17.

[0019] The towed measuring device includes a DC motor 19, a worm gear reducer 20, and a tow bar 21. The DC motor 19 and the worm gear reducer 20 are fixedly installed on the left front side of the hull 1. The main shaft of the DC motor 19 is connected to the input shaft of the worm gear reducer 20. The output shaft of the worm gear reducer 20 is vertically upward and connected to the front end of the tow bar 21. The rear end of the tow bar 21 is connected to a traveling ADCP 22.

[0020] When not conducting measurements, the Doppler ultrasonic velocimeter 7, the dual-frequency depth sounder 8, and the underway ADCP22 were removed and placed on the deck of hull 1, aft of the bridge 3. The working principle and technical effects of this utility model are described below: 1) The control panel in the driver's cab 3 is equipped with a positioning device, which can record the trajectory of the survey vessel in real time to verify whether the back-and-forth trajectories are consistent during the survey vessel test. The connecting rod is a hollow tube, and the data signal line connected to the instrument passes through the inside of the connecting rod. The data signal line is connected to the driver's cab 3.

[0021] 2) The hull 1 of the online monitoring vessel of this utility model is made of aluminum alloy. This ensures both the strength of the hull 1 and its light weight. It can effectively reduce the draft of the measuring vessel, ensuring the normal operation of the measurement work, and is particularly suitable for shallow waterways such as the Yellow River.
