An installation block is connected to the outer surface of the lower end of the drain pipe. A fastener is sleeved on the installation block. Connecting suspension rods are connected to the periphery of the lower end of the fastener. An installation support frame is connected to the outer surface of the lower end of the connecting suspension rod. A filter screen is connected to the middle of the installation support frame. A leakage receiving tray is sleeved on the outer surface of the lower end of the installation support frame. A water guide pipe is connected to the middle of the lower end of the leakage receiving tray.
