Abstract
Description
Technical Field
[0001] This invention belongs to the field of hydrological flow measurement technology, specifically relating to a multi-element hydrological flow measurement device. Background Technology
[0002] Hydrological cableway stations are mainly used for measuring parameters such as velocity, water depth, and sediment content at cross-sections of rivers and canals. They include winches, cableways, lead weights, supports, storage structures, and control systems. In China, the velocity and flow rate at cross-sections primarily rely on propeller current meters, radar current measurement, and Doppler current measurement. These three methods are based on different principles and have different advantages and disadvantages.
[0003] One traditional measurement technique is the propeller current meter method. This method involves placing a current meter in the water flow to capture the water velocity in real time, and then combining this with cross-sectional parameters to calculate the flow rate. It can directly obtain point flow data and offers high measurement accuracy. However, this method is complex to operate, requiring professionals to wade through water or travel by boat to set up the current meter. Furthermore, the measurement range is limited by the current meter's placement conditions, especially in deep or turbulent waters where placement and operation are difficult.
[0004] Radar current measurement uses radar technology to emit microwaves to the water surface and receive the reflected signals. The flow velocity is calculated based on the Doppler effect. The main advantage of this method is its non-contact measurement and wide measurement range. However, this method is primarily for water surfaces and is highly sensitive to surface conditions. When the water flow velocity is low, the frequency deviation of the reflected signal is slight, making it susceptible to environmental noise interference. The presence of floating debris, waves, or foam on the water surface can cause attenuation or distortion of the reflected signal, thus reducing measurement accuracy.
[0005] Doppler flow measurement involves emitting ultrasonic waves into the water flow and using the Doppler frequency shift effect produced by the ultrasonic waves scattering through tiny particles and bubbles in the water to calculate the flow velocity. This method offers high measurement accuracy and strong environmental adaptability, making it suitable for complex flow conditions such as deep water and rapid currents. However, the instruments used in Doppler flow measurement are relatively expensive, and a certain level of operational skill is required.
[0006] Acoustic Doppler flow profiler (ADCP) works by emitting sound waves into water, which are then scattered by scattering bodies in the water. The echo signals returned by the scattering bodies are received, and the flow velocity is calculated by analyzing the Doppler effect frequency shift. It can simultaneously acquire flow velocity and direction data at different depths in the water. It features non-disturbance of the flow field, high measurement efficiency, high accuracy, complete information, short measurement time, and a large velocity measurement range. However, there are blind zones at the edges of the measurement area.
[0007] In summary, the above-mentioned flow measurement methods are applicable to different flow velocities and different river cross sections, but they all have certain limitations. Therefore, it is necessary to design a multi-element hydrological flow measurement device to use the above-mentioned flow measurement methods simultaneously in order to obtain more accurate flow measurement data.

It should be noted that the connection method between the first, second, and third flow velocity meters and the radar flow velocity unit and the control system is conventional. Specific models of the first, second, and third flow velocity meters and the control system are not improvements of this application and will not be elaborated upon here.
[0030] like Figures 2 to 5As shown, preferably, the radar speed measuring unit includes a bracket 31, a radar velocity meter 32, a level gauge 33, a lifting cable 34, and a retraction structure 35. The retraction structure 35 is mounted on the overhead crane frame 13. The lifting cable 34 is connected to the bracket 31 and the retraction structure 35. The bracket 31 is located below the overhead crane frame 13. The retraction structure 35 controls the extension length of the lifting cable 34, thereby controlling the lifting and lowering of the bracket 31. The radar velocity meter 32 and the level gauge 33 are both mounted on the bracket 31 and move up and down with the bracket 31. The detection ends of the radar velocity meter 32 and the level gauge 33 face away from the overhead crane frame 13, and the level gauge 33 is a height-measuring radar. The radar velocity meter 32, the level gauge 33, and the retraction structure 35 are all electrically connected to the control system. It should be noted that the connection method between the radar velocity meter, the level gauge, the retraction structure, and the control system is a conventional connection.

These three current meters are three different types of flow meters, each used for flow measurement, acquiring three types of flow data. Simultaneously, the motor 351 drives the drum 252 to rotate, lowering the lifting cable 34. The support 31 descends towards the water surface, and the level gauge 33 monitors the distance between the water surface and the support. The distance between the radar current meter 32 and the water surface is inferred. Based on the monitoring of the liquid level sensor 33, the control system controls the operation of the motor 351 to adjust the optimal height of the radar current meter 32 above the water surface and emits microwaves towards the water surface to measure the flow.
