technical field

The utility model relates to the technical field of sluices, in particular to a sluice control device with adjustable water speed.

Background technique

Sluice gates are low-head hydraulic structures built on river channels and channels that use gates to control flow and adjust water levels. Closing the gate can block floods, block tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industry and domestic water; opening the gate can release floods, waterlogging, abandoned water or wastewater, or Supply water to downstream rivers or channels. In water conservancy projects, sluice gates are widely used as structures for retaining, discharging or taking water.

At present, small sluice gates generally use the way of manually rotating the runner to lift the gate in the gate frame to achieve the purpose of opening and closing the gate. However, when the flow velocity of the water flow in the water supply pipeline is too large and the total amount of water is too large, the huge impact force directly hits On the gate, the difficulty of opening and closing the gate by turning the wheel is increased, and there are certain limitations.

Further, the shut-off and pressure-relief mechanism includes an iron disc arranged in the water supply pipe, a rotating rod is inserted through the middle of the iron disk, and the outer side wall of the water supply pipe is symmetrically provided with up and down with the rotating rod. Two through holes matched at both ends, bearings are installed in the two through holes, the upper and lower ends of the rotating rod pass through the two bearings respectively and then continue to extend outward and are fixedly sleeved with gears, the water supply Two telescopic mechanisms are symmetrically and fixedly installed on the outer side wall of the pipe, and racks are fixedly connected to the output ends of the two telescopic mechanisms, and the two racks are respectively engaged with two gears.

Further, the outer side walls of the upper and lower ends of the rotating rod are respectively fixed to the inner rings of the two bearings by means of key connection.

Further, two sealing rings respectively sleeved on the upper and lower ends of the rotating rod are arranged in the two through holes.

Further, the telescopic mechanism is a telescopic cylinder or a hydraulic cylinder.

The advantages and positive effects that the utility model has are:

When the water flow velocity in the water supply pipe is too large and the total amount of water body is too large, the output ends of the two telescopic mechanisms are controlled to extend to drive the two racks to move synchronously. The interception of water flow greatly reduces the instantaneous pressure on the gate caused by the water body at one end of the water supply pipeline close to the gate frame, and relieves the difficulty of opening and closing the gate by manually turning the runner.
