Problems solved by technology

The current discharge gates are only functional but not landscape and practical. The landscape discharge gates built in recent years are all vertical to the river and arranged along a straight line. The landscape is not strong, nor does it have high strength, corrosion resistance and timely operational technical effects

Embodiment 1

[0021] A discharge gate for water conservancy projects, comprising a first gate, a second gate, a first gate control device and a second gate control device;

[0022] The material of the first gate is high-strength steel plate, and its composition is calculated by weight percentage: C: 0.15%, Si: 0.18%, Mn: 1.6%, Ti: 0.06%, Ni: 1.69%, Cr: 11%, Nb: 0.03%, Mo: 0.52%, Ce: 0.03%, the balance is Fe and unavoidable impurities;

[0023] The volume percentage of acicular ferrite in the microstructure of the high-strength steel plate is 38%, and the volume percentage of island martensite is 21%;

[0024] The material of the second gate is high-alloy cast iron, and its composition is calculated by mass percentage: C: 2.8%, Si: 1.9%, Mn: 1.5%, Ni: 2.1%, Cr: 0.6%, RE: 0.11%, The balance is Fe and impurities;

[0025] The first gate is a plate-shaped object with neatly arranged through holes, the number of which is 30, arranged in animal patterns, and the second gate is a plate-shaped ob...

Embodiment 2

[0027] Drilling treatment is carried out after the first gate plate described in embodiment 1 is formed, and the following heat treatment steps are carried out after drilling:

[0028] (1) Put the semi-finished product of the first gate after drilling into the resistance furnace and heat it to 1080°C with the furnace, keep it warm for 39 minutes, and then take it out of the furnace for air cooling;

[0029] (2) Put the semi-finished product after the soaking treatment in step (1) into the annealing furnace and heat it to 760°C, and keep it warm for 39 minutes;

[0030] (3) Place the semi-finished product obtained in step (2) directly into a cryogenic box to cool down to -92°C without cooling after it is released from the oven, keep the temperature for 28 minutes, and return to room temperature after being released from the oven;

[0031] (4) Put the semi-finished product obtained in step (3) into a tempering furnace and heat it to 290°C, keep it warm for 32 minutes, and then t...

Abstract

The invention relates to an escape gate which is used for hydraulic engineering and flows through urban or scenic rivers. Through specific structure design and improvement on the material of the escape gate, the landscape property, high strength and safety are ensured under the condition of low cost.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering construction, in particular to a water discharge gate which can be applied to landscape land. Background technique [0002] The function of the water discharge gate is to block the river water in good time and open it when needed. The current discharge gates are only functional but not landscape and practical. The landscape discharge gates built in recent years are all vertical to the river and arranged along a straight line. The landscape is not strong, nor does it have high strength, corrosion resistance and timely Operational technical effects. Contents of the invention [0003] The object of the present invention is to propose a water discharge gate for water conservancy projects. [0004] Specifically, it is achieved through the following technical means: [0005] A discharge gate for water conservancy projects, comprising a first gate, a second gate, a first gate control dev...
