The invention discloses a water drain pipe, and belongs to the field of drainage pipelines. The water drain pipe can prevent insects and dangerous articles from entering the water drain pipe. The water drain pipe comprises a section of inclined pipe and a section of straight pipe, a spring frame fixed to the inner wall of the straight pipe is arranged in a pipe cavity of the upper half section ofthe straight pipe, a piston matched with the pipe cavity of the straight pipe is arranged below the spring frame, the spring frame and the piston are connected up and down through an extension spring,several longitudinal leakage holes are evenly machined in the circumference of the pipe wall of the lower half section of the straight pipe, and a baffle capable of preventing the piston from being disengaged from the pipe cavity of the straight pipe is machined on the lower end face of the straight pipe. When flowing water flows from top to bottom, the impact force of the flowing water impacts the piston downwards, so that the piston slides downwards to reach the lower half part of the straight pipe, and the flowing water flows out through the leakage holes; and after the water flow passes,the impact force disappears, the elastic restoring force of the spring promotes the piston to move upwards to the original position before the piston moves downwards, one-time opening and closing drainage process is completed, and winged insects and crawlers cannot enter the water drain pipe. The water drain pipe is suitable for buildings needing drainage.
本发明公开了一种泄水管，它属于排水管道领域，它可以阻止虫类及危险物品进入。它包含一段斜管和直管，在直管上半截的管腔内设置有一固定于直管内壁上的簧架，簧架下方设置有一与直管管腔相吻合的活塞，一拉伸弹簧将簧架和活塞上下连接起来；在直管下半截的管壁圆周上均匀地加工有几道纵向方向的漏孔，在直管的下端面上加工有能防止活塞脱离直管管腔的挡板；当有流水从上向下流动时，流水的冲击力会向下冲击活塞从而使得活塞向下滑动到达直管的下半截部位，流水就会通过漏孔流出来；水流通过后，冲击力消失，弹簧的弹性恢复力促使活塞上移直到下移前的原位置，完成一次开关泄水过程，飞虫爬虫无法进入。本设计适合于需要排水的建筑物。
