OVERTURNING-CUM-FLOATING AUTOMATIC WATER GATE, FOR DISCHARGING ACCUMULATED SLUDGE EASILY AND PREVENTING THE DAMAGE OF A WATER GATE

摘要

Purpose: in the neighbouring bottom of a groove, an automatic water gate for toppling and flowing passes through to discharge pollutants and is arranged to prevent secondary pollution easily heap to a sluice gate and prevents the damage of the sluice gate by water pressure or big impurity. Construction: the automatic water gate for toppling and flowing contains: a sluice gate (10) positioning selectively clogs the interval between the both walls (11) in a channel; One rotating link unit (20) is fixed to forming on the upper surface of sluice gate (10) by a rotating link axis (21) and is rotatably fixed on rotating link axis (21) with a rotating link (22); To the rear portion for rotating main a cylinder (30) and a piston rod (31) of sluice gate (10) before a piston rod (31) around rotating link axis (21) to the other end of rotating link (22) by rotatably connecting below sluice gate (10) rotatably; The link shaft (41) of a rotation on the side by being fixed to wall (11) rotatably forms the link unit (40) of a rotation, one end is fixed to the connection (42) of a rotation of rotating link axis (21) and the other end is fixed to the link shaft (41) of rotation, and a connecting rod (43), it is fixed in the link shaft (41) of the rotation of the connection (42) from other side to rotation; One secondary cylinder (50) rotates sluice gate (10) around the link shaft (41) of rotation, by rotatably connecting before a piston rod (51) to the other end of connecting rod (43) and rotatably wall (11) leans on the rear portion of one side fixed piston rod (51).
