Fig. 3 to 6 show the operation of the gate of the present invention:

process 1:

when the gate normally blocks water, the main gate 1 is positioned in the middle of the gate pier 2 to block upstream water flow and floating garbage from leaking downwards, and the auxiliary gate 11 is positioned inside the left gate pier 2;

the nut 163 arranged in the mortise 16 of the main gate 1 is positioned at the side of the screw 164, is tightly screwed with the thread at the top end of the screw 164, and provides pressure for the door tenons 18 of the main gate 1 and the auxiliary gate 11, in the process, the main gate 1 and the auxiliary gate 11 are in a connection and fixed state, and the water-stopping rubber 162 arranged at the connection side of the main gate 1 and the auxiliary gate 11 is compacted to play a water-stopping and seepage-preventing effect.

And (2) a process:

when the gate is crossed the water and is decontaminated, on the basis of process 1, the shrink of opening and closing rod 14, the drive gate moves the certain distance to right side gate pier 2 along spout 174 on the bottom plate 22, upstream rivers are let off through the overflow mouth 13 of sub-gate 11, floating garbage is then arranged in the trash ring 3 interception of overflow mouth 13 low reaches face, the rivers that let off impact stator 35 and go into low reaches river course or the inside cavity of gate pier 2 down, trash ring 3 rotates to left side gate pier 2 direction, transport floating garbage to the inside cavity of gate pier 2, floating garbage falls into the net of decontaminating 4, the excessive surplus water yield of the inside cavity of gate pier 2 is arranged to low reaches river course from water service valve 24.

When the main gate 1 is overhauled, on the basis of the process 1, the opening and closing rod 14 is contracted to drive the gate to move along the sliding groove 174 on the bottom plate 22 until the main gate 1 completely enters the cavity in the right gate pier 2, and the auxiliary gate 11 plays a role in water retaining; and (4) closing the water valve 24, draining accumulated water in the cavity inside the gate pier 2 to a downstream river channel through a water pump, and overhauling the main gate 1.

The main gate 1 is replaced by the following modes: in addition to the above process, the nut 163 is rotated and moved from the screw 164 side to the screw 165 side, the connection between the main shutter 1 and the sub-shutter 11 is released, and the main shutter is lifted up by the main lifting point 191 on the top of the main shutter 1, and the subsequent operation is performed.

When the auxiliary gate 11 is overhauled, on the basis of the process 1, the opening and closing rod 14 extends to drive the gate to move along the sliding groove 174 on the bottom plate 22 until the auxiliary gate 11 completely enters the cavity inside the gate pier 2 on the left side, the main gate 1 plays a role in retaining water, and the subsequent process is the same as the process 3.

When the gate is opened flood discharge entirely, on process 1's basis, the pole 14 extension that opens and shuts, the drive gate moves along spout 174 on the bottom plate 22, until the sub-gate 11 gets into 2 inside cavities of left side gate piers completely, close the water service valve 24, discharge 2 inside cavities ponding of gate pier to the low reaches river course through the water pump, remove the net of decontaminating 4, remove main gate 1 and sub-gate 11's being connected, the pole 14 that opens and shuts shortens, drive main gate 1 and get into 2 inside cavities of right side gate pier, open the water service valve 24 of both sides gate pier 2.
