[0099]

[0100]

[0101]

[0102]

[0103] In the above formula, f p is the spectrum peak frequency, and the spectrum peak rise factor γ takes an average value of 3.3.

[0104] When simulating irregular waves, the significant wave height and period are input into the computer for wave spectrum simulation.

[0105] To avoid the influence of wave multiple reflection in the harbor basin, the machine is stopped after each wave making and sampling is completed, and then repeated wave making is performed after the water surface is calm.

[0107] ② The allowable deviation of the simulated value of the peak frequency is ±5%;

[0108] ③ In the range where the spectrum density is greater than or equal to 0.5 times the peak value of the spectrum density, the allowable deviation of the spectrum density distribution is ±15%;

[0109] ④ The allowable deviation of the significant wave height, effective period or spectrum peak period is ±5%;

[0110] ⑤ The allowable deviation of the ratio of the 1% cumulative frequency wave height, effective wave height to average wave height in the simulated wave train is +15%.

[0111] The calibration of the test wave height is performed after the placement of the breakwater model. The wave element verification point is located 2.5m outside the east breakwater root at the water intake head. H 4% The average value of the wave height is taken as the calibration result and compared with the target value, and H 1% The wave height value is used as the wave making parameter for the formal test when the simulation results are the same or similar. Then the water intake head and culvert model are placed for testing.

[0112] During the formal test, wave height meters are arranged near the water intake head, on both sides of the culvert, in the breakwater reconstruction section and outside the original breakwater to test the wave height distribution near the engineering area.

[0113] Working principle: in the installation of water taking head 2 on the culvert pipe 3, first, the water pump 6 can be started to suck the water in the experimental pool 1 into the control box 9 through the suction pipe 10, and then the water is transported into the installation box 5 through the connecting pipe 8, the water pump 6 and the delivery pipe 7, at this time, the water can be sprayed into the experimental pool 1 through the first shunt pipe 13 and the plurality of spray heads 15, so that the water in the experimental pool 1 can be impacted to form waves, and the water taking head 2 is impacted from the N direction, when it is needed to change the flow direction of the spray, the driving motor 23 can be started to drive the screw rod 24 to rotate through the two driving bevel gears 25, at this time, under the threaded transmission of the threaded plate 26, the connecting cover 19 can be moved to the rear side along the sliding cover 21, so as to move the moving rod 20, at this time, the baffle 17 can be pulled to the rear side, so that the baffle 17 moves in an arc shape, and the moving rod 20 can be moved to the right side along the connecting cover 19, at this time, the moving rack 30 can be moved under the meshing transmission of the reset gear 29, so that the driving shaft 28 can be rotated, so that the torsional spring 31 can exert a torsional force, so that the torsional spring 31 is in a stressed state, the torsional spring 31 in the stressed state can provide power for the reverse rotation of the reset gear 29, so as to provide power for the movement of the moving rod 20 to the connecting cover 19, after the first shunt pipe 13 is blocked by the end cover 18 located at the rear side of the baffle 17, at this time, the water can be discharged through the second shunt pipe 14 and the plurality of corresponding spray heads 15, so as to generate waves in the W direction of the water taking head 2, so that the water taking head 2 is impacted by the spray in the W direction, the transmission motor 36 can be started to drive the lead screw 35 to rotate through the meshing transmission of the two connecting bevel gears 37, at this time, the moving cover 34 can be moved vertically under the threaded transmission of the nut 38, when the moving cover 34 moves downward, the flow of water through the U-shaped plate 32 can be reduced, so as to reduce the impact force of the spray on the water taking head 2, when the moving cover 34 moves upward, the flow of water through the U-shaped plate 32 can be increased, at this time, the spray can be increased, so as to increase the impact force on the water taking head 2, therefore, the impact force of the spray can be adjusted according to the needs, so as to accurately test the impact resistance of the water taking head 2 when the water taking head 2 is impacted, therefore, the technical scheme has good practicability.
