Double-leaf flap gate

Abstract

The invention provides a double-leaf flap gate. The double-leaf flap gate comprises an upper leaf gate leaf and a lower leaf gate leaf, the upper leaf gate leaf and the lower leaf gate leaf are both horizontal gates and are both arranged at a river channel gate opening, the upper leaf gate leaf is rotated upwards to be opened, and the lower leaf gate leaf is rotated downwards to be opened. The double-leaf flap gate further comprises an upper hoist driving the upper leaf gate leaf to rotate upwards to be opened or rotate downwards to be closed and a lower hoist driving the lower leaf gate leafto rotate downwards to be opened or rotate upwards to be closed, one end of the upper hoist is hinged to the upper leaf gate leaf, one end of the lower hoist is hinged to the lower leaf gate leaf, theother end of the upper hoist and the other end of the lower hoist are both hinged to a hoist base, and the joint of the upper leaf gate leaf and the lower leaf gate leaf is flush with the landscape water level of the inland river.

Description

technical field [0001] The invention relates to the technical field of hydraulic gates, in particular to a double-leaf flap gate. Background technique [0002] Gates are widely used in flood control, drainage, water storage, irrigation and other fields. Many sluices in coastal areas often take into account the functions of flood protection (tide) and drainage. The water level meets the landscape and ecological requirements, so many sluices also take into account the function of maintaining the water level of the inland river landscape. Due to the large changes in the flood (tide) water level of the outer river in the coastal area, and the need to take into account the navigation function, the scale of the gate is relatively large. At present, the landscape gates suitable for this type of function are mainly upper or lower horizontal gates. Hydraulic hoist, this type of gate has no towering structure across the water surface, and the landscape coordination is better. [000...

AI Technical Summary

Problems solved by technology

[0005] The tide in the Pearl River Delta is a semi-diurnal tide, that is, there are two tides and ebbs and flows every day, and affected by the ebb and flow of the tide, the sluice needs to change frequently between the tide-blocking and drainage conditions, and the gate needs to be opened and closed frequently, which affects the gate and hoist service life, while installation and maintenance are very inconvenient, increasing management and operating costs
