Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a flood control gate for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to eliminate harm and promote benefits. Building flood control gates can avoid the impact of natural disasters.

[0003] However, existing flood control gates usually have a simple structure, and most of them use motors to drive the screw rods, which drive the gates to move through threaded transmission. After the sluice gate is closed, the gate will be pressed against the gate frame under the action of water pressure, resulting in a large starting force required when opening, which increases the burden on the drive motor and thus affects the service life. Utility Model Content

[0007] Preferably, the rotating rod is rotatably connected to the flood-proof stone trough, the output end of the servo motor is fixedly connected to the rotating rod, and the side of the flood-proof plate close to the rotating rod is lighter than the side away from the rotating rod.

[0008] Preferably, the winding roller is fixedly connected to the rotating rod, and two winding rollers are provided and symmetrically mounted on the outer wall of the rotating rod.

[0009] Preferably, one end of the steel wire rope away from the casting cement block is fixedly mounted on the outer wall of the winding roller, and the steel wire rope passes through the flood control board inside.

[0010] Preferably, the flood prevention plate is rotatably connected to the fixing rod, and the limiting plate is slidably connected to the flood prevention plate.

[0011] Preferably, the limit plate is arranged above the wire rope, and the gear is rotationally connected to the shaft rod.

[0012] Preferably, the shaft rod is fixedly connected to the flood control plate, the gear is provided with a hole corresponding to the screw rod, and the screw rod is threadedly connected to the flood control plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Before the flood arrives, the new type of flood control gate can start the servo motor, which drives the rotating rod to rotate, and the rotating rod drives the winding roller to rotate, the winding roller reels the wire rope, and the wire rope drives the flood control plate to rotate, and the flood control plate turns to a vertical state to prevent floods. When flood discharge is required later, the servo motor is started, and the servo motor drives the rotating rod to rotate in the opposite direction, and the rotating rod drives the winding roller to rotate, the winding roller releases the wire rope, and the flood control plate rotates along the direction of the water flow. The servo motor does not require a large starting force, thereby reducing the burden on the servo motor and ensuring the service life of the servo motor.

[0015] After long-term use, the new flood control gate can inspect and repair the wire rope. When the wire rope needs to be replaced, the screw is unscrewed from the flood control plate, and the grip is held to rotate. The grip drives the gear to rotate, the gear drives the tooth plate to move, the tooth plate drives the connecting rod to move, and the connecting rod drives the limit plate to move, so that the limit plate no longer blocks the wire rope. The wire rope is taken out of the flood control plate and replaced with a new one. The operation is simple and quick, and will not affect the flood control plate. BRIEF DESCRIPTION OF THE DRAWINGS
