Description

Technical Field

[0001] The present invention relates to the technical field of gates, and in particular to a quick-assembly gate mechanism and method that are easy to maintain. Background Art

[0002] Gates are control devices used to close and open discharge channels. They are important parts of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. We usually install regulating cast iron gates on the water pipelines of some water intake and supply projects to regulate and control flow as needed. Inspection gates are generally installed at the water inlet of pump stations and the inlet and outlet of some tunnels, culverts, inverted siphons, etc. to provide conditions for the maintenance of hydraulic structures and pump equipment. Flood discharge working gates are generally installed on the overflow dam or spillway of the reservoir to control the water level of the reservoir and the flood flow discharged to the downstream, so as to maximize the functional benefits of the reservoir. In water conservancy projects, gates are one of the important components of hydraulic structures. They can close the orifices of the building as needed, or open the orifices completely or partially to regulate the upstream and downstream water levels and flows, thereby obtaining benefits such as flood control, irrigation, water supply, power generation, navigation, and rafting. It can also be used to remove floating objects, silt, ice, etc., or provide the necessary conditions for the maintenance of related buildings and equipment. Cast iron gates are usually set at the inlets and outlets of water intake and water transfer buildings. The gates are flexibly and reliably opened and closed to exert their functions and benefits and maintain the safety of the buildings. The gates on the market are generally steel gates, cast iron gates, reinforced concrete gates and prefabricated gates. Among them, prefabricated gates are the most widely used because of their light structure, which can meet the bearing capacity requirements of the foundation and can be used for soft silt with extremely poor geological conditions; they can adapt to the uneven settlement of the foundation, and the gate chamber section, water inlet section, and water outlet section have strong integrity and greater rigidity; the more sluices are built, the more obvious the benefits are, and they are suitable for centralized prefabrication and processing, the pouring quality is easy to guarantee, and a large amount of templates can be saved.

[0003] However, traditional prefabricated gates have the following disadvantages:
