Railed arc double-door flood control gate

Abstract

The invention discloses a railed arc double-door flood control gate. The railed arc double-door flood control gate comprises door hinges which are symmetrically fixed on both banks of a river; fan-shaped gates are connected on the railed arc double-door flood control gate respectively through the two symmetrical door hinges; each fan-shaped gate is hinged to the corresponding door hinge through two main supporting arms; an arc rail corresponding to each fan-shaped gate is arranged at the bottom of the fan-shaped gate; each fan-shaped gate rotates along the arc rail, with the door hinge corresponding to the fan-shaped gate as a center, to close or open the two fan-shaped gates so as to close or open the control gate. The railed arc double-door flood control gate is simple in structure; the railed arc double-door flood control gate ensures barrier-free sailing inside a wide sailing channel, so that the river has relatively good passability; the railed arc double-door flood control gate can meet a requirement of a controller on relatively high passability; the railed arc double-door flood control gate is easy to maintain, low in cost and succinct in arrangement, and gives consideration to an attractive appearance, so that the railed arc double-door flood control gate can be harmonious with surrounding buildings better.

Description

technical field [0001] The invention relates to the technical field of flood control gates, in particular to a flood control gate with railed arc double doors. Background technique [0002] According to the requirements of engineering construction tasks, it is necessary to build flood control gates on wider waterways, and to ensure the free passage of ships in this waterway, that is, it is required that there are no structures hindering water flow in the wider waterway, the river surface is transparent, and the gates are required to have adequate control devices. Therefore, the determination of the gate type of the throttling gate is very critical. [0003] The selection of control gates needs to meet the requirements of safety, reliability and convenient operation, that is, under the premise of safety and reliability, it is convenient to operate and easy to maintain; the gate strives for economical and reasonable requirements, that is, the layout is simple and the cost is e...
