The water drainage flap comprises a flap column, a water drainage plate arranged inside the flap column and a water drainage rotation shaft connected with the water drainage plate. The durability testing apparatus for the water drainage flap comprises: a vibration table for providing vertical reciprocal vibration and a water inlet flange disc fixed on the vibration table for supplying water to the water drainage flap, wherein the water inlet flange disc comprises a base fixed to the vibration table and a water inlet column arranged on the base and facing the water drainage flap, a water inlet is provided in the water inlet column, the water inlet column and the flap column enclose a water inlet chamber, and the water inlet communicates with the water inlet chamber. ## Claims ### Claim 1 A durability testing apparatus for a water drainage flap to test the durability of the water drainage flap, the water drainage flap comprising a flap column, a water drainage plate arranged inside the flap column and a water drainage rotation shaft connected with the water drainage plate, wherein the durability testing apparatus for the water drainage flap comprises: a vibration table for providing vertical reciprocal vibration and a water inlet flange disc fixed on the vibration table for supplying water to the water drainage flap, wherein the water inlet flange disc comprises a base fixed to the vibration table and a water inlet column arranged on the base and facing the water drainage flap, a water inlet is provided in the water inlet column, the water inlet column and the flap column enclose a water inlet chamber, and the water inlet communicates with the water inlet chamber. ### Claim 2 (depends on 1) The durability testing apparatus for the water drainage flap according to claim 1, wherein an overflow port in communication with the water inlet chamber is arranged in the water inlet column. ### Claim 3 (depends on 2) The durability testing apparatus for the water drainage flap according to claim 2, wherein the water inlet flange disc comprises an overflow valve connected to the overflow port. ### Claim 4 (depends on 3) The durability testing apparatus for the water drainage flap according to claim 3, wherein the water drainage flap further comprises a water drainage control apparatus connected to the water drainage rotation shaft, wherein the water drainage control apparatus is configured to control the water drainage rotation shaft to drive the water drainage plate to rotate, and is fixed to the flap column and the water inlet flange disc. ### Claim 5 (depends on 4) The durability testing apparatus for the water drainage flap according to claim 4, wherein the water inlet flange disc further comprises fixing blocks fixed to the base and lugs fixedly connected to the fixing blocks, and the water drainage control apparatus is fixedly connected to the lugs. ### Claim 6 (depends on 5) The durability testing apparatus for the water drainage flap according to claim 5, further comprising a water discharging column arranged on the water drainage flap and at a side away from the water inlet flange disc, wherein the water discharging column and the flap column enclose a water discharging chamber, and the water drainage plate is arranged between the water discharging chamber and the water inlet chamber. ### Claim 7 (depends on 6) The durability testing apparatus for the water drainage flap according to claim 6, wherein a water outlet is arranged in the water discharging column. ### Claim 8 (depends on 7) The durability testing apparatus for the water drainage flap according to claim 7, wherein the water drainage control apparatus further comprises a pressure sensor for detecting a water pressure in the water inlet chamber. ### Claim 9 (depends on 8) The durability testing apparatus for the water drainage flap according to claim 8, further comprising a high-pressure water tank in communication with the water inlet, wherein the high-pressure water tank comprises a pressure regulating apparatus for controlling a water pressure of water entering the water inlet chamber. ### Claim 10 (depends on 9) A testing method using the durability testing apparatus for the water drainage flap according to claim 9, the testing method comprising the following steps: S1: starting the vibration table to simulate vibration influence to a water drainage activity during operation; S2: supplying water by the high-pressure water tank to the water inlet chamber to simulate a work environment of the water drainage flap; and regulating water pressures using the pressure regulating apparatus to simulate different work conditions; S3. detecting a water pressure in the water inlet chamber by the pressure sensor, when the water pressure in the water inlet chamber exceeds a set value, activating the overflow valve to reduce the water pressure in the water inlet chamber: when the water pressure in the water inlet chamber does not exceed the set value, controlling the water drainage rotation shaft by using the water drainage control apparatus to drive the water drainage plate to rotate, so as to control different water drainage angles, whereby drained water enters the water discharging chamber and is discharged from the water outlet.
