Flexible joint for large-sized water-taking pump boat

Abstract

The invention relates to a flexible joint for a large-sized water-taking pump boat comprising a vertical sleeve joint, a vertical rotary sleeve, a horizontal sleeve joint and a horizontal rotary sleeve, wherein a water discharging opening is formed in the side wall or the bottom of the vertical sleeve joint; the vertical rotary sleeve is arranged at the top of the vertical sleeve joint in a rotary sealed state through a turning wheel supporting device; the horizontal sleeve joint is fixedly connected onto the vertical rotary sleeve; the horizontal rotary sleeve is movably connected to one side or two sides of the horizontal sleeve joint in a sealed manner, and is provided with water feeding openings. The vertical rotary sleeve and the vertical sleeve joint, and the horizontal rotary sleeve and the horizontal sleeve joint, which are mutually and rotatably connected, are adopted to respectively realize the rotary flexible connection of water conveying pipes between the pump boat and a shore base along a vertical axis and a horizontal axis; and the flexible joint can be used under movement, swinging and rotation of the pump boat in vertical and horizontal directions, and has the advantages of simple structure, low manufacturing cost, safety in use, long service life, good applicable performance and wide application range.

Description

technical field [0001] The invention relates to an active joint, in particular to an active joint used by a large pump boat to safely take water at different water levels in rivers, lakes or mountain reservoirs. Background technique [0002] At present, water intake pump boats are widely used for water intake in rivers, lakes or mountain reservoirs. Advantages: simple structure, convenient construction, short cycle, low cost; high water intake efficiency, good water quality, not affected by factors such as changes in water level and fluctuation frequency influences. The difficulty in the design of water pumping ships is how to solve the impact of water level fluctuations on the water delivery pipes connecting the hull and shore piers. There are two methods currently in use: [0003] 1. A metal hose is installed at the connection between the water delivery pipe and the hull and shore pier. When the water level changes and the hull moves and swings, the metal hose bends. Di...

Problems solved by technology

[0005] In order to solve the problem of automatic adjustment of the connection between the large-diameter water pipe pump ship and the shore pier as the water level changes, the invention provides a simple structure and firm connection, which can meet the needs of the pump ship due to changes in water flow, wind and waves, and water level fluctuations. It is used for water intake in the environment of vertical and horizontal movement, swing and rotation, which improves the safety and efficiency of water intake by pump ships and prolongs the service life of water pipes.
