[0003] Water is likely to accumulate at the fixed bottom plate of the electric tail wing; in the existing drainage device, a drainage shell is installed on the fixed bottom plate, and a drainage pipe is installed at the bottom of the drainage shell to drain water; a sealing ring is usually installed between the drainage shell and the fixed bottom plate; the sealing ring is between the drainage shell and the fixed bottom plate. Due to the tolerances in the manufacturing process of the parts, for example, the fitting surface of the groove of the fixed bottom plate is uneven, and the sealing ring does not fit tightly with it, there is a risk of water leakage; there are manufacturing tolerances in the thickness of the sealing ring, and the thickness of the sealing ring produced in each batch will be different. If the thickness of the sealing ring is small (the lower limit of the size), there will be a gap between the drainage shell and the fixed bottom plate, and the sealing effect is not good, resulting in water leakage; there are manufacturing and processing errors at the connection between the drainage shell and the fixed bottom plate, and there are manufacturing and processing errors at the connection of the fixed bottom plate, which are also prone to water leakage.
