Lifting tilting flapgate

Abstract

A lifting tilting flapgate relates to a gate used in hydraulic engineering and comprises a gate leaf and a gate pier, wherein beams at two sides of the gate leaf are respectively provided with a protruding hanger shaft and an upper and a lower protruding cantilever roller wheel; and the gate pier is provided with two vertical gate slots respectively matched with respective corresponding lower cantilever roller wheels and two tracks respectively matched with respective corresponding upper cantilever roller wheels. The lower cantilever roller wheel can be used as a trunnion so that the gate leaf can rotate around the center of the trunnion, or the lower cantilever roller wheel can roll in the gate slot so that the gate leaf can rise and tilt out of the water surface to overhaul position. The regular start or close operation of a gate is the same as that of the flapgate. When overhaul is needed and the gate is in close position, the upper cantilever roller wheel of the gate is put in place and the gate topples over to form a lifting tilting gate. By adopting the roller wheels to substitute for the fixed trunnion in the prior art, the gate simultaneously has the advantages of the flapgate and the lifting tilting gate and overcomes the defects that the flapgate is difficult to overhaul and the lifting tilting gate affects navigation.

Description

【Technical field】 [0001] The invention relates to a water conservancy engineering gate. 【Background technique】 [0002] In water conservancy projects, the more widely used are rising-horizontal gates and flap gates. in, [0003] The flap gate is a rotary flat gate, that is, the gate leaf rotates around the hinge fixed on the foundation (gate pier or bottom sill) to open and close the gate. The hinge can be set in the middle or bottom of the gate leaf. [0004] The horizontal gate is also a plane gate. When the gate is closed, it stands upright in the orifice. After the gate is lifted and opened, the door leaf moves along a certain track, and finally lies on the top of the orifice. [0005] Problems and disadvantages of the existing gates: the flap gate with a hinge at the bottom is operated by a hoist, rotates around the hinge, turns over and sinks into the water and lies on the gate bottom plate to open, and stands up to close. When the gate is fully open, there is no bu...

AI Technical Summary

Problems solved by technology

[0005] Problems and shortcomings of existing gates: the flap gate with bottom hinge is operated by hoist, rotates around the hinge, turns over and sinks into the water, lies on the bottom plate of the gate to open, and stands upright to close

However, the gate is connected to the foundation by a support hinge, so it is impossible to propose water surface maintenance.

When the horizontal gate is fully opened, it lies on the top of the hole, which limits the navigation height, especially the navigation hole with high channel level
