Technical Field

[0001] The utility model relates to a diversion gate, belonging to the technical field of water gates. Background Art

[0002] A sluice is a low-head hydraulic structure built on rivers and channels that uses gates to control flow and regulate water levels. Closing the gates can block floods, tides or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industry and domestic water use; opening the gates can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining, discharging or taking in water.

[0003] Some existing diversion gates pump water from nearby rivers when in use, and a large amount of plants often remain in the water. After long-term use, the plants will accumulate on the lower side of the gate, thereby affecting the drainage efficiency of the gate and the water delivery efficiency. Now there is an urgent need for a diversion gate to solve the above problems. Utility Model Content

A servo motor is fixed on the upper end surface of the support top plate, and a screw is installed on the output end of the servo motor and is rotatably connected to the threaded sleeve. A through hole is provided inside the gate plate.

[0007] Furthermore, the diversion flow grooves are provided in a plurality of groups, and the sizes of the plurality of diversion flow grooves are equal and they are symmetrically provided on the front and rear end surfaces of the water baffle.
