Automatic open-close flap gate provided with longitudinal oblique shaft

Abstract

The invention provides an automatic open-close flap gate provided with a longitudinal oblique shaft. The automatic open-close flap gate comprises a barrage, a gate pier, a gate, a downstream panel, anupstream panel, a baffle bar, the oblique shaft, an oblique shaft support plate, a drainage hole, a bracket, a bracket hole, an upper oblique shaft hole, a lower oblique shaft hole, a floating box, floating box guide rails, a water inlet hole, floating box turning wheels, upper hook plates, lower hook plates, a sliding door, vertical plates, a horizontal baffle, a control board, a control board groove, sliding door turning wheels, an adjusting screw, a gate cavity, a contact support, sliding door guide rails and a limiting block. The flap gate is automatically opened and closed in the lateraldirection, and mounting of oil pressure opening and closing facilities is not required; the gate constitutes a damping system, additional damping is not required, the problems that the gate is damaged and the service life of the gate is affected due to the fact that the flap gate is flapped, vibrated and impacted in the turnover process can be solved, the problem of shielding and blocking due tosuspending of the gate in the middle of the gate chamber after the horizontal flap gate is opened is solved, water discharging is smoother, and the potential risk that gate closure is affected by thefact that floating objects are hooked on the gate is eliminated.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, in particular to an inclined-axis longitudinal automatic opening and closing flap gate. Background technique [0002] The hydraulic flap gate is a kind of energy-saving and environment-friendly gate with completely independent intellectual property rights developed by our country's water conservancy engineering technicians after more than 50 years of hard work; the most widely used flap gate is the hydraulic transverse flap The working principle of the gate is lever balance and rotation. Specifically, the hydraulic horizontal flap gate uses hydraulic power and the weight of the gate to check and balance each other, and the purpose of regulating the water level is achieved by adding a damping feedback system: when the upstream water level rises, the gate will "wind" The "horizontal axis" gradually opens to discharge; on the contrary, when the upstream water level drops, the g...

[0002] The hydraulic flap gate is a kind of energy-saving and environment-friendly gate with completely independent intellectual property rights developed by our country's water conservancy engineering technicians after more than 50 years of hard work; the most widely used flap gate is the hydraulic transverse flap The working principle of the gate is lever balance and rotation. Specifically, the hydraulic horizontal flap gate uses hydraulic power and the weight of the gate to check and balance each other, and the purpose of regulating the water level is achieved by adding a damping feedback system: when the upstream water level rises, the gate will "wind" The "horizontal axis" gradually opens to discharge; on the contrary, when the upstream water level drops, the gate gradually closes around the "horizontal axis" to store water, so that the upstream water level is always kept within the scope of the design requirements; that is, when the upstream flow increases, the upstream water level of the gate rises. High, when the torque of the water pressure to the fulcrum is greater than the torque of the door weight and various damping to the fulcrum, the gate will automatically open; and when the upstream flow is reduced to a certain extent, the torque of the door weight to the fulcrum is greater than the water pressure and various damping to the fulcrum When the torque is high, the hydraulic transverse flap gate can return and close by itself; the hydraulic transverse flap gate has the advantages of no external energy, simple structure, self-opening and closing under unmanned operation, reliable operation, convenient management and maintenance, and low cost. Many successful experiences have been accumulated in the operation, but there are still many problems in the operation, such as the gate is prone to beating, vibration and impact during the flipping process, which is likely to cause damage to the gate and affect the life of the gate; in addition, due to In the open state, the gate hangs in the middle of the lock chamber, occupying a large water-passing area and affecting the water-passing capacity. Floating objects are also easy to jam the gate and cause the gate to fail to close.
