Anti-overflow non-main path drainage device capable of ascending and descending autonomously according to change of water yield
The invention discloses an anti-overflow non-main path drainage device capable of ascending and descending autonomously according to change of water yield. The device comprises a pipeline. A cavity isformed in the pipeline. The device can be adjusted timely according to the size of water yield. When the water yield is relatively small, water in any direction is discharged from an auxiliary drainage pipe in an annular groove, and water flushes the auxiliary drainage pipe, so that a J-shaped platen upwarps and then a filter screen in the direction is jacked up to play an anti-blocking role. When the water yield is relatively large and the annular groove is inadequate to drain water, water is discharged from a top main drainage pipe primarily, so that a flood preventing device right below pushes downward, and an ejector rod further jacks up a well cover to increase the displacement. A semi-circular baffle plate can prevent a backflow phenomenon effectively.
本发明公开的一种防溢水且根据水量变化自主升降的非主路排水装置，包括管道，所述管道内设有空腔，本发明根据水量的大小能及时作出调整，当水量较小时，任一方向水从环形凹槽内的副排水管中排入，水冲过副排水管使得J形台板翘起，然后该方向过滤网被顶起，可以起到防堵塞的作用，当水量较大时即环形凹槽不足以排水时，水主要从顶部主排水管排入，使得正下方防涝装置下压，继而使顶杆顶起井盖，增大排水量，半圆形挡板可以有效阻止倒灌现象发生。
