Multi-channel flow-making device and method for large-scale experimental water tank

A multi-channel flow-making device for a large-scale experimental water tank, comprising:

• a large-scale experimental water tank bottom (1), flow-making water pumps (2), flow meters (3), pressure gauges (4), a lower annular backflow corridor (5), outflow corridors for gradual transition section (6), upper corridors (7), and a control system, wherein the outflow corridors for gradual transition section (6), a plurality of flow-making water pumps (2), and the upper corridors (7) are sequentially arranged on two sides of the large-scale experimental water tank bottom (1);
• two ends of the flow-making water pump (2) are communicated with the outflow corridor for gradual transition section (6) and the upper corridor (7), respectively;
• the lower annular backflow corridor (5) is horizontally arranged around a periphery of the large-scale experimental water tank bottom (1) in an annular direction;
• the upper corridors (7) are located above the lower annular backflow corridor (5) and arranged along a wall of the large-scale experimental water tank;
• the upper corridors (7) are communicated with the lower annular backflow corridor (5);
• and the lower annular backflow corridor (5) is filled with water;
• the flow-making water pumps (2) on one side of the large-scale experimental water tank bottom (1) serve as outflow water pumps for water pumping, and the flow-making water pumps (2) on the other side serve as backflow water pumps for water discharging;
• each flow-making water pump (2) is equipped with the flow meter (3) and the pressure gauge (4);
• the flow meter (3) serves for collecting flow rate data from the flow-making water pump (2);
• and the pressure gauge (4) serves for collecting pressure data from the flow-making water pump (2);
• and
• the control system is electrically connected to the flow meters (3) and the pressure gauges (4);
• and the control system is capable of monitoring and adjusting the operating status of the flow-making water pumps (2) in real-time, regulating operating parameters of the flow-making water pumps (2) according to the data collected by the flow meters (3) and the pressure gauges (4), and adjusting the operating status of the flow-making water pumps (2) according to testing requirements.
