Rapid and precise guiding and sealing flood gate

Abstract

A rapid and precise guiding and sealing flood gate is mainly composed of a starting and stopping device, a sealing door frame and a gate body, wherein the starting and stopping device is fixed to a concrete foundation, the gate body is driven by the starting and stopping device to move up and down in the sealing door frame, the upper ends, arranged at the hole opening position, of the two sides of the gate body are respectively connected through a vertically-arranged lead screw through transmission pair fixing pieces, the upper ends of the lead screws are connected with commutators arranged on the concrete foundation and are respectively connected with a speed reducer through a horizontally-arranged coupler, the speed reducer is arranged in the middle, the two sides of the gate body are tightly matched with side sealing grooves of the sealing door frame respectively through strip-shaped side bearing devices which are connected together, and the side bearing devices move up and down in the side sealing grooves. A strip-shaped upper bearing device and a lower bearing device which are transversely arranged are arranged on the upper portion and the lower portion of the gate body respectively, and an upper sealing groove and a lower sealing groove which are matched with the upper bearing device and the lower bearing device respectively and are transversely arranged are formed in the upper portion and the lower portion of the sealing door frame respectively. The rapid and precise guiding and sealing flood gate has the advantages of being reasonable in structure, convenient to mount and use, capable of being rapidly started and stopped, reliable in sealing and the like.

Description

technical field [0001] The invention relates to a fast, precise guiding and sealing flood control gate used in urban flood control projects, and belongs to the technical field of gates in water conservancy projects. Background technique [0002] Because cities are often bordered by rivers, lakes or oceans, they are all threatened by different types of floods. Due to the dense population and high wealth density in cities, it is often required that the urban flood control gates be fast and reliable within the embankment range of hundreds of meters or even thousands of meters. At present, the gates used for urban flood control in water conservancy projects mainly include the following forms: [0003] 1. Mobile flood gate. This kind of gate is generally composed of movable vertical steel columns and aluminum alloy stacked beams. Before the flood comes, the vertical steel columns are manually fixed on the embankment by bolts, and the aluminum alloy stacked beams are inlaid one ...

AI Technical Summary

Problems solved by technology

This kind of gate is widely used in Europe, such as Prague, the capital of the Czech Republic. However, the assembly and disassembly of this flood control gate requires a lot of manpower for protection, which is time-consuming and laborious. It cannot be installed in a short time, and it also faces troubles in water leakage, storage, transportation and management.

[0004] 2. Traditional plane steel gate

This kind of gate is a new technology that has emerged in recent years. It combines the characteristics of rubber dams and steel gates. By inflating the rubber dam bags, the steel gates can be erected to achieve the purpose of flood protection. It is easy to use, but it has high cost and rubber dam The dam bag is vulnerable to damage and aging, and its reliability needs to be improved
