FIG. 2 is a schematic view of a water accumulation tank at a gate;

FIG. 3 is a schematic view of a drain at a gate;

FIG. 4 is a schematic diagram of the connection of two ends of the penstock;

wherein: 1. the water collecting tank is characterized by comprising a water collecting tank, a plug, an adapter plate, a conduit connector, a water conduit, a flange, a screw, a safety ring, a chain ring, a sleeve nut and a flat nozzle.

Detailed Description

Two rectangular grooves are formed on the floor at the front section of the gate to form an embedded floor integrated water accumulation groove 1, a water leakage hole is formed at the bottom of the water accumulation groove 1, a water conduit 5 is designed below the water leakage hole, and accumulated water is discharged out of the machine body through a hole formed in a lower wall plate, as shown in figures 1-4.

A water diversion apparatus according to the present utility model will be described in detail with reference to the accompanying drawings.

The utility model provides a drainage device of gate department, includes floor integration ponding groove 1, blocks up 2 on the floor face, blocks up screw 7, lock ring 8, chain 9, chain link 10 on, and the adapter plate 3 of riveting under the floor face, conduit coupling 4, water conduit 5, ring flange 6 under the adapter plate.

The floor at the gate is processed in blocks, the floor close to the gate is formed into 2 concave water receiving tanks 1 by sheet metal forming, and the length of the water receiving tanks can include accumulated water formed by the gate. Two water leakage holes are formed in the left end and the right end, the shape of the groove ensures that the water leakage holes are formed at the lowest position, and the position selection cannot influence personnel on the machine to collide with each other due to blockage. The screw 7 and the nut with the safety holes at the head are arranged in the plug 2, the safety ring 8 and the chain 9 are arranged on the safety holes, and the other end is connected to the floor structural member in a rivet mode by using the chain ring 10, so that the situation that the plug is lost after being opened is avoided.
