The concrete embodiment of the cut-off device for water conservancy construction provided by the utility model comprises:

referring to fig. 1 to 4, a cut-off device for water conservancy construction comprises a mounting frame 1 and a flashboard 2; in this embodiment, the mounting frame 1 is a rectangular frame structure, and the mounting frame 1 is fixedly mounted on the dam body 6. A chute 11 is arranged on the inner side of the mounting frame 1; the flashboard 2 sets up in mounting bracket 1 inboard, and flashboard 2 both sides edge stretches into spout 11 and along spout 11 vertical slip, makes flashboard 2 can follow the spout 11 slip lift of mounting bracket 1, and mounting bracket 1 and spout 11 provide the direction for the lift of flashboard 2, guarantee the stability of flashboard 2 lift.

The flashboard 2 is connected with a buoyancy tank 3 towards the upstream side, the buoyancy tank 3 is of a hollow shell structure, and the cross section area of the lower part of the buoyancy tank 3 is larger than that of the upper part. The lower part of the buoyancy tank 3 has a larger cross-sectional area, so that the lower part of the buoyancy tank has enough water displacement, and the lower part of the buoyancy tank 3 can provide enough buoyancy to support the gravity of the buoyancy tank and the flashboard 2 when the draft is small, thereby reducing the water blocking area and ensuring the water flow throughput in a conducting state, namely in a non-intercepting state.

The upper side of the buoyancy tank 3 is provided with an opening 32, and the opening 32 enables the inside air and the outside air of the buoyancy tank 3 to be communicated, so that the smoothness of water inlet and water drainage of the buoyancy tank 3 is ensured. The upper end of the buoyancy tank 3 extends to close to the upper end of the shutter 2 to avoid water ingress through the opening 32 of the buoyancy tank 3.

Two water guide pipes 31 are symmetrically connected to the bottom of the buoyancy tank 3, and valves 4 are installed on the water guide pipes 31. In some embodiments, the valve 4 is a waterproof automatic valve to facilitate control of the opening and closing of the valve 4. The water guide pipe 31 provides a channel for river water to enter the buoyancy tank 3, the valve 4 is opened, the river water enters the buoyancy tank 3, the buoyancy tank 3 no longer provides buoyancy, and the flashboard 2 automatically descends.

The water pump 5 is installed to flashboard 2 upside, and flashboard 2 upper end is provided with the supporting seat 21 that supports water pump 5. The water pump 5 is installed at a high position so that the water pump 5 is not in contact with the river water.

The water pump 5 is used to pump out the water in the buoyancy tank 3. The water inlet end and the water outlet end of the water pump 5 are respectively connected with a water inlet pipe 51 and a water outlet pipe 52, the water inlet pipe 51 extends to the bottom of the inner side of the buoyancy tank 3, a water outlet at the tail end of the water outlet pipe 52 is positioned at the downstream side of the flashboard 2, and a bracket 22 for supporting the water outlet pipe 52 is arranged at the downstream side of the upper end of the flashboard 2; the water pump 5 can discharge water in the buoyancy tank 3 through the water inlet pipe 51 and the water outlet pipe 52. In other embodiments, the water pump 5 may not be mounted on the upper side of the shutter 2, but mounted on the upper side of the buoyancy tank 3 or on the side of the mounting frame 1 or on the side of the dam 6 or independently provided, so long as the water inlet pipe 51 of the water pump 5 can extend to the bottom of the buoyancy tank 3.

Working principle: when the valve 4 is closed and the buoyancy tank 3 is internally free of water, the buoyancy tank 3 can provide buoyancy in river water, so that the flashboard 2 automatically rises along the chute 11 of the mounting frame 1, as shown in the state of fig. 4, the lower part of the buoyancy tank 3 has a certain draft, the provided buoyancy is balanced with the gravity of the buoyancy tank 3, the flashboard 2 and the water pump 5, and at the moment, the river water can flow through the lower part of the mounting frame 1.

When the river water needs to be shut off, the valve 4 is opened, the river water flows into the buoyancy tank 3, the buoyancy tank 3 cannot provide buoyancy, and the buoyancy tank 3, the water pump 5 and the flashboard 2 fall under the action of self gravity to form the river water shutoff, as shown in fig. 1. When the flashboard 2 is required to ascend, the valve 4 is closed, so that the water pump 5 works to pump out the water in the buoyancy tank 3, and the buoyancy tank 3 can provide buoyancy.
