[0021] Specifically, each boat is composed of a boat base and a boat body, and a performance detection device is arranged between the base and the body of each boat, the performance detection device comprising a test block, a microprocessor, a pressure sensor and an angular displacement sensor. The pressure sensor and the angular displacement sensor are fixed on the boat through the test block, and both are connected with the microprocessor. The pressure sensor can obtain the pressure value of the contact surface between the test block and the pool, and when the boat moves, the action force between the two ends of the test block and the pool is the rowing force of all the test team members; the angular displacement sensor can obtain the deflection angle of the test block relative to the boat, and through the angular displacement sensor, the boat angle overturning caused by the unbalanced rowing force of the team members on both sides of the boat can be detected, thereby providing a reference for the force difference between the team members on both sides.

[0022] Specifically, the first boat A and the third boat C are single-side paddle boats, and the corresponding left rowing pool and right rowing pool are single-side paddle rowing pools; the second boat B is a double-side paddle boat, and the corresponding middle rowing pool is a double-side paddle rowing pool. The directions of the bow of the first boat A and the third boat C are the same, and the direction of the bow of the second boat B is opposite to that of the first boat A and the third boat C; the water flow directions of the second flow channel 2 and the third flow channel 3 are the same, the water flow directions of the first flow channel 1 and the fourth flow channel 4 are the same and opposite to those of the second flow channel 2 and the third flow channel 3. Figure 1As can be seen, the first boat A is uniformly set to the right as the rowing position, the third boat C is uniformly set to the left as the rowing position, and the second boat B adopts rowing on both sides at the same time. This setting covers a variety of rowing situations, and the training adaptability is more diversified. The flow direction of the water flow in each flow channel depends on the water inlet direction and the backwater direction of the water tank in the water circulation system. The first flow channel 1 and the second flow channel 2 form a water circulation, and the third flow channel 3 and the fourth flow channel 4 form a water circulation.

[0023] Specifically, the first flow channel 1 is provided with a first flow meter 11, the second flow channel 2 is provided with a second flow meter 12, the third flow channel 3 is provided with a third flow meter 13, and the fourth flow channel 4 is provided with a fourth flow meter 14. The outside of the pool is provided with an electric control hub 15, which includes a water pump protector, a circuit breaker, a frequency converter, a CPU, a control adjustment program, etc. The electric control hub 15 is respectively connected with the first water pump 61, the second water pump 91, the first flow meter 11, the second flow meter 12, the third flow meter 13, the fourth flow meter 14, and the performance detection device. The flow meter is used to measure the current water flow rate and feedback to the electric control hub 15. The electric control hub 15 adjusts the water flow rate by controlling the water pump outlet speed as needed.

[0024] Specifically, the front ends of the second flow channel 2 and the third flow channel 3 are provided with ballast grilles 17, and the rear ends of the first flow channel 1 and the fourth flow channel 4 are provided with ballast grilles 17 (the shape is shown in Figure 2 ). The ballast grilles 17 cover the cross sections of the first spouting port 5 and the second spouting port 8, which can increase the stability of the water flow, eliminate waves and splashes, and make the water produced by the water pump more smoothly into the flow channel. Figure 3 As shown in the drawings, the shape characteristics of the first spouting port 5 and the second spouting port 8 are: the upper and lower are straight, the left and right are semicircular bends, which are similar to the structure of a playground track. The lower straight of the first spouting port 5 and the second spouting port 8 is not less than 50mm from the pool bottom, and the upper straight of the first spouting port and the second spouting port is not less than 200mm from the water surface. The position of the first spouting port 5 is higher than the second backwater port 10, and the position of the second spouting port 8 is higher than the first backwater port 7. In actual application, the same segment of the spouting port is 1.5% higher than the backwater port, which is beneficial to increase the water flow rate.

[0025] Specifically, the pool is a circulating pool, the water produced by the first water pump 61 in the first water tank 6 flows into the second flow channel 2 and the third flow channel 3 through the first spouting port 5, and after flowing through the entire second flow channel 2 and the third flow channel 3, it is collected into the second water tank 9 through the second backwater port 10. The water produced by the second water pump 91 in the second water tank 9 flows into the first flow channel 1 and the fourth flow channel 4 through the second spouting port 8, and after flowing through the entire first flow channel 1 and the fourth flow channel 4, it is collected into the first water tank 6 through the first backwater port 7, thereby completing the water circulation.

[0026] The specific working process of the embodiment is as follows: first, the target flow rate is set through the touch panel 16 of the electric control center 15, the start button is clicked, the electric control system receives the start signal, the first water pump 61 and the second water pump 91 are started, the water of the first water pump 61 flows into the second flow channel 2 and the third flow channel 3 through the first spouting port 5, the water generated by the second water pump 91 flows into the first flow channel 1 and the fourth flow channel 4 through the second spouting port 8, the output power of the water pump motor is gradually increased by adjusting the program control inverter, the flow rate of the water pump is increased, and the water flow rate is increased. In this process, the flow rate meter monitors the water flow rate in real time, and when the water flow rate reaches the target flow rate, a feedback signal is fed back to the electric control center 15, the output frequency of the frequency converter is fixed, and then the output power of the water pump is controlled to be stable, so that the effect of stabilizing the water flow rate is achieved. If the water flow rate needs to be changed, the output power of the water pump is controlled again through the frequency converter, the water flow rate is adjusted, and the water flow rate is controlled.
