Embodiment 1

[0060] This embodiment provides a flood gate 500, such as figure 1 , 2 As shown, it includes a panel structure that is rotatably blocked on the flood discharge hole 402, the panel structure has a panel body 501, the direction of the panel body 501 facing the water flow is the water-facing surface, and the water-facing surface of the panel body 501 is at least two It is arc-shaped in different directions; at the same time, a support structure is arranged on the side of the panel body away from the water-facing surface, one end of the support structure is connected with the side of the panel body away from the water-facing surface, and the other end is connected to the side wall of the flood discharge hole. The support blocks are connected in rotation, and the setting of the support structure can increase the bearing capacity of the panel body 501;

[0061] When a surface is under pressure, in theory, the more severe the bending, the greater the pressure it can withstand; when ...

Embodiment 2

[0069] This embodiment provides a flood discharge system, such as Figure 4 , 5 As shown in the figure, it includes a lock chamber, and a flood discharge hole is opened on the lock chamber; the flood discharge gate 500 described in the embodiment is rotated and arranged in the lock chamber; There is a second state that avoids the opening of the spill hole.

[0070] The upper end of the flood discharge hole is the lintel 400 of the flood discharge hole. The matching surface of the flood discharge hole lintel 400 and the panel body is an arc surface, and the matching surface of the flood discharge hole lintel 400 is matched with the upstream surface of the panel body. Lintel 400 turn setting.

[0071] A sealing plate 403 protruding toward the panel body is provided on the flood discharge hole lintel 400, and cooperates with the top water stop 502. When the panel body is blocked in the flood discharge hole, the flood discharge hole lintel 400 and the panel body are sealed again...

Embodiment 3

[0074] This embodiment provides a water jet prevention device, which is applied in the flood discharge system in the second embodiment. This embodiment provides a water jet-proof sealing device, which is suitable for sealing the hyperboloid gate 500, such as Image 6 , 7 As shown, it includes: a movable water seal assembly 100, a fixed water seal assembly 200 and a drive assembly 300; one end of the fixed water seal assembly 200 is connected to the lintel 400 of the flood discharge hole, and the other end is provided with a movable water seal assembly 100. The movable water seal assembly 100 is driven by the drive assembly 300 to move the fixed water seal assembly 200; the movable water seal assembly 100 has a main seal 102, and the shape of the main seal 102 matches the shape of the panel of the gate 500, which can achieve tightness Sealing; the drive assembly 300 has multiple groups, which are arranged at intervals along the extending direction of the fixed water seal assem...

Abstract

The invention provides a flood discharge gate and a flood discharge system, and belongs to the technical field of hydraulic engineering, and the flood discharge gate comprises a panel structure rotationally arranged on a flood discharge opening in a blocking mode; the panel structure is provided with a panel body, and the upstream face of the panel body is in a cambered surface shape in at least two different directions. One end of the supporting structure is connected with the side, away from the upstream face, of the panel body, and the other end of the supporting structure is rotationally connected with the supporting block between the flood discharge hole side walls; according to the flood discharge gate, the upstream face of the panel body is in the cambered surface shape (called hyperbolic curved surface) in at least two different directions, so that the stress state is optimal, the mechanical property is improved, the thickness of the panel is reduced, and manufacturing materials are saved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a flood discharge gate and a flood discharge system. Background technique [0002] The flood gate is mainly used to release flood water and adjust and control the water level of the reservoir. It has the ability to withstand various static and dynamic loads, the ability to open and close in dynamic water, and has good structural and hydraulic characteristics. It has become an indispensable and important structure, and it can be seen everywhere in major rivers at home and abroad. [0003] At present, the height of the retaining dam is getting higher and higher, and the requirements for the flood gate are also getting higher and higher. The low head flood gate generally adopts the flat gate, and the medium and high head flood gate generally adopts the arc gate. [0004] However, the force-bearing surface of the flat gate is flat, and the force-bearing surface of the ...
