Embodiment

[0011] refer to figure 1 , the present embodiment provides an anti-surge and exposed-top planar gate. The gate is provided with a stack of barriers between the normal water storage level and the tidal water level on the upper part of the exposed-top planar gate 2 in front of the exposed-top arc-shaped working gate 1. The tide-blocking gate 3 of the inter-water body, the top of the open-top plane gate 2 is provided with a water-seal support seat 4 at the bottom of the tide-blocking gate.

[0012] The open-top planar gate 2 and the tide-blocking gate 3 are in the closed water-retaining state at ordinary times, and the open-top arc-shaped working gate 1 is in the closed state without pressure. 2. Open the open-top arc working gate 1 again.

Abstract

The invention provides a tidal bore resistance top-exposed plane gate, and belongs to the technical field of water resources and hydropower engineering. According to the tidal bore resistance top-exposed plane gate, a tidal bore blocking gate for blocking a water body between a normal pool level and a tidal bore water level is arranged on the upper part of a top-exposed plane gate in front of a top-exposed working gate in an addition mode, so as to solve the problems that an existing technology cannot meet needs of hydropower stations or water conservancy projects with large tidal bore or windwaves, and the safe risk is large.

Description

technical field [0001] The invention relates to a surge-proof and exposed-top planar gate, which belongs to the field of water conservancy and hydropower engineering. Background technique [0002] For hydropower stations or water conservancy projects with relatively large tidal surges or wind waves, due to the large difference between the tidal surge water level and the normal water storage level, some projects can reach more than 10m. If the curved working gate is designed according to the tidal water level, the opening height of the open-top arc working gate is too high, reaching more than 30m, resulting in a long stroke of the hydraulic press beyond the existing technical level, and the large scale of the gate leads to a large increase in investment; If it is designed according to the normal water storage level, a large tide gushing from the top of the open-top arc working gate will form a negative pressure at the rear of the gate leaf, causing airbags to impact the gate ...
