Abstract
The invention provides a tidal bore prevention exposed top type planar gate, which is characterized in that a tidal bore blocking gate for blocking water bodies between normal water storage levels and tidal bore water levels is additionally arranged at the upper part of the exposed top type planar gate in front of an exposed top type arc-shaped working gate. The problems that the prior art is difficult to meet requirements and the safety risk is high for hydropower stations or hydraulic engineering with large tidal bore or stormy waves are solved. Belongs to the technical field of hydraulic and hydroelectric engineering.
Description
Technical Field
The invention relates to an anti-tidal bore open top type plane gate, and belongs to the field of hydraulic and hydroelectric engineering.
Background
For hydropower stations or hydraulic engineering with larger tidal bore or stormy waves, because the tidal bore water level is larger than the normal water storage level, some projects can reach more than 10m, if the exposed top type arc-shaped working gates such as water retaining surface holes, water discharge gates, spillways and the like are designed according to the tidal bore water level, the height of the opening of the exposed top type arc-shaped working gate is too high to more than 30m, the stroke of the hydraulic machine is overlong than the prior art level, and the large scale of the gate causes more investment; if the water storage device is designed according to the normal water storage level, after the large tidal bore flows out from the top of the exposed top type arc-shaped working gate, negative pressure is formed at the rear part of the gate leaf of the gate, the air bag is generated to impact the gate to cause damage, and the arc gate support arm is sometimes unstable and damaged to cause large engineering accidents, so that the prior art is still imperfect and needs to be further improved.
Disclosure of Invention
The invention provides an anti-tidal bore open top type plane gate, which aims to solve the problems that the prior art is difficult to meet the requirements of hydropower stations or hydraulic engineering with larger tidal bore or stormy waves, and the safety risk is larger.
In order to solve the problems, the tidal bore protection top-exposed planar gate is designed to be adopted, and a tidal bore blocking gate for blocking water bodies between normal water storage levels and tidal bore levels is additionally arranged at the upper part of the top-exposed planar gate in front of the top-exposed arc-shaped working gate.
In the tidal bore prevention tidal bore blocking gate, a tidal bore blocking gate bottom water seal supporting seat is arranged at the upper part of the exposed top type plane gate;
the exposed top type plane gate and the tidal gate are in a closed water blocking state at ordinary times, the exposed top type arc-shaped working gate is in a non-pressure closed state, the tidal gate and the exposed top type plane gate are sequentially lifted out during water drainage, and then the exposed top type arc-shaped working gate is opened.
Compared with the prior art, the invention has the advantages that the upper part of the traditional top-exposed planar gate is provided with the tidal gate for blocking the water body between the normal water storage level and the tidal water level, the gate is used for blocking water at ordinary times, the arc-shaped working gate is in a pressureless closing state, when larger tidal or storm occurs, the water level can not be flushed out through the tidal gate at the upper part, the arc-shaped working gate is not influenced by tidal or storm, the investment is less, the top-exposed planar gate and the panel of the tidal gate are on the same plane, compressed air can not be generated at the joint of the two gates basically, the upper part of the tidal gate is higher than the tidal or storm, the ventilation is full, and compressed air can not be generated basically, so that the gate is impacted by the pressure of an air bag, and the safety of the gate structure is effectively ensured; the upper part of the exposed top type plane gate is provided with a tidal blocking gate bottom water seal supporting seat, so that the tight contact between the tidal blocking gate bottom water seal and the exposed top type plane gate is effectively ensured, and the water stopping effect is enhanced; when water is discharged, the tide gate and the exposed top type plane gate are sequentially provided, and then the arc-shaped working gate is opened, so that the water discharge flow and the water flow state are not influenced.

Detailed Description
For the purpose of promoting an understanding of the principles of the invention, reference will now be made in detail to the embodiments described herein, including examples, illustrated in the accompanying drawings.
Examples
Referring to fig. 1, the present embodiment provides a tidal bore protection top-exposed planar gate, which is characterized in that a tidal bore blocking gate 3 for blocking a water body between a normal water storage level and a tidal bore level is additionally arranged at the upper part of a top-exposed planar gate 2 in front of a top-exposed arc-shaped working gate 1, and a tidal bore blocking gate bottom water seal supporting seat 4 is arranged at the upper part of the top-exposed planar gate 2.
The exposed top type plane gate 2 and the tidal gate 3 are in a closed water blocking state at ordinary times, the exposed top type arc-shaped working gate 1 is in a non-pressure closed state, the tidal gate 3 and the exposed top type plane gate 2 are sequentially lifted out during water drainage, and then the exposed top type arc-shaped working gate 1 is opened.
