Water stop device for water conservancy project of safe large aqueduct structure

Abstract

The invention relates to the technical field of water conservancy projects, and particularly relates to a water stop device for a water conservancy project of a safe large aqueduct structure. The water stop device comprises an aqueduct and a hoist arranged on the upper side of the aqueduct, wherein a top plate is arranged over the hoist; one end of the top plate is fixedly connected with a vertical plate; the upper surface of the top plate is provided with a penetrating hole concentric with a screw; two round holes are symmetrically formed in the upper surface of the top plate; a rotating rodis arranged in the round holes and sleeved with a bearing; the bearing is arranged on the upper sides of the round holes and fixedly connected with the top plate; three hemispherical covers are annularly installed on the outer surface of the upper end of the rotating rod at equal intervals; the lower end of the rotating rod is fixedly connected with a round rod; two supporting plates are symmetrically installed on the outer surface of the round rod; and bristles making contact with the screw are installed at the ends, away from the round rod, of the supporting plates. Compared with the prior art, the water stop device has the following beneficial effects that the purpose of sweeping rust stains on the screw is achieved, and the probability that the rust stains are attached to the screw isreduced.

Description

technical field [0001] The invention relates to a water stop device for water conservancy projects with a safe large-scale aqueduct structure, which belongs to the technical field of water conservancy projects. Background technique [0002] The aqueduct is an important link in the water conveyance project, and it is the realization condition for the river to cross valleys and rivers. In our country, aqueducts are mainly used for irrigation, water delivery, sand discharge, flood discharge, etc. Some large aqueducts can also be used for navigation. Aqueducts are playing an increasingly important role in my country's water delivery projects. With the continuous development of my country's construction technology and water delivery projects in recent years, large-scale aqueducts are more and more widely used in practice, and the construction technology of large-scale aqueducts directly affects whether the entire water delivery project can run smoothly. [0003] At present, the...

Problems solved by technology

[0003] At present, the hoist is often used to control the gate to cut off the water of the aqueduct, but the screw installed in the hoist is exposed to the outside for a long time and is prone to rust and rust. When using the hoist to drive the screw to move, it will cost more It takes less time to clean the rust stains on the screw. In an emergency, it is easy to cause a major accident due to failure to stop the water in time.
