19-21, the present utility model also provides a water diversion gate system comprising a working gate 200 and a service gate 100, the service gate 100 being in front, the working gate 200 being behind, the gate being behind a culvert. The access door 100 is a stop log type down-the-hole door as described above. The working gate is arranged in a gate slot at the water diversion gate hole and forms a fit with a guide rail I201 in the gate slot. The access door is arranged in a door slot at the access door hole and forms a fit with a guide rail II101 in the door slot, and a hanger rail 104 is arranged above the side door slot. The guide rail II101 includes a front guide rail 1011, a rear guide rail 1012, and an inner guide rail 1013, the front guide rail 1011 is provided on the front groove wall of the side door groove, the rear guide rail 1012 is provided on the rear groove wall, the inner guide rail 1013 is provided on the inner groove wall, the main slider 51 and the side water are both in sliding fit with the rear guide rail 1012, the sub slider 52 is in sliding fit with the front guide rail 1011, and the roller 54 is in rolling fit with the front guide rail 1011. The working gate 200 is driven to lift by two 160kN double-hoisting-point hoisting hoists 202. The lifting lug of the access gate 100 is connected with two 50kN automatic hanging and taking-off beams 102 through a steel wire rope, and the automatic hanging and taking-off beams 102 are hooked by two 50kN movable electric hoists 103 to realize lifting. The movable electric hoist 103 walks on the hanger rail 104.

Normally, the gate is closed; when water is guided, the working gate 200 moves the water gate; after the water diversion is finished, the working gate 200 moves water to close the gate. When overhauling, the overhauling gate 100 is placed in the gate hole, the top water stop 35 is sealed with the top wall surface of the gate hole, and the bottom water stop II44 of the lower gate is sealed with the bottom surface of the gate hole. After the maintenance is finished, the working gate 200 is closed, and the gate is opened by still water after the horizontal pressure of the internode. During non-service periods, the service gate 100 is stored in a management station. The hooks of the double-hoisting point hoist 202 should mate with the lifting lugs of the access door 100. The trash rack is co-recessed with the access door 100.

When the overhaul gate is opened, the movable electric hoist 103 firstly lifts the upper section gate and transfers the upper section gate to a gate slot on one side for temporary storage, and then lifts the lower section gate and transfers the lower section gate to the gate slot on one side for temporary storage. The opposite steps are performed when the gate is closed. Therefore, the lifting weight of the movable electric hoist 103 is obviously reduced every time, so that the power and capacity requirements on the movable electric hoist 103 are also reduced, and the investment of equipment is reduced. Because the water retaining area of the single-section gate is reduced, the whole structure and the material consumption can be reduced, thereby greatly reducing the manufacturing cost.

It should be noted that if the gate hole height is higher, the bottom of the upper gate may be sequentially overlapped with the lower gate to realize the change of the overall height.
