Water gate for heating and freezing prevention in water conservancy project

Abstract

The invention discloses a water gate for heating and freezing prevention in a water conservancy project. The water gate comprises a portal frame, dam matrixes, a wire winder, a gate plate and sealingguide rails. The wire winder is arranged on the portal frame. The sealing guide rails are vertically arranged on the side faces of the dam matrixes correspondingly. The gate plate is arranged betweenthe two sealing guide rails. Lifting rings are arranged at the top of the gate plate. Steel wire ropes connected with the lifting rings are arranged on the wire winder. Each sealing guide rail comprises C-shaped box iron and T-shaped steel, wherein the T-shaped steel is arranged on the back face of the C-shaped box iron. The two sides of the gate plate extend into openings of the C-shaped box ironcorrespondingly. Electric heating bars are axially arranged in each piece of T-shaped steel. In this manner, according to the water gate for heating and freezing prevention in the water conservancy project, when the sealing guide rails are frozen due to low air temperature, power supply circuits of the electric heating bars are started, the interiors of the sealing guide rails are heated, and therefore frost on the surfaces of the sealing guide rails is thawed, and the gate plate can smoothly ascend and descend.

Description

technical field [0001] The invention relates to the technical field of sluice construction, in particular to a heating and anti-freezing sluice in water conservancy projects. Background technique [0002] A sluice is a low-head hydraulic structure built on a river channel or channel using a gate to control flow and adjust water level. Closing the gate can block flood, keep tide or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industrial and domestic water; opening the gate can vent flood, waterlogging, abandoned water or waste water, or Supply water to downstream channels or channels. In water conservancy projects, sluices are widely used as structures for retaining, releasing or taking water. [0003] When the sluice is closed, the lower part of the ram is immersed in water. In cold seasons, the water flow near the ram is easy to freeze and affect the normal opening and closing, whic...

AI Technical Summary

Problems solved by technology

[0003] When the sluice is closed, the lower part of the gate is immersed in water. In cold seasons, the water flow near the gate is easy to freeze and affect the normal opening and closing. Improvement is needed.
