Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a flood discharge device for water conservancy projects. Background Art

[0002] As an important means for mankind to cope with water resource utilization and flood prevention and disaster reduction, water conservancy projects play an irreplaceable role in protecting people's lives and property and promoting economic and social development. With the intensification of global climate change and the frequent occurrence of extreme weather events, flood disasters have become one of the severe challenges facing the world.

[0003] For example, Chinese patent CN202222693497.2 discloses a flood diversion channel for water conservancy projects. By setting supporting poles, mounting base blocks, stacking blocks, insertion grooves, docking grooves, docking strips, frame slots, protective net frames and protective nets, the upper end of the channel plate is installed with mounting base blocks and stacking blocks through the supporting poles. When the water level of the flood rises, the number of stacking blocks can be increased, and the stacking blocks can be installed on the outside of the supporting poles using the insertion grooves, and stacked and installed in conjunction with the connection of the docking strips and the docking grooves, so that the height of the flood diversion channel can be increased by using the increased stacking blocks, and flood diversion can be carried out to cope with higher water levels. In addition, the supporting poles can also serve as guardrails to prevent unauthorized personnel from slipping into the flood diversion channel, thereby playing a protective role.

[0004] However, in actual use, the flood diversion channel needs to be constructed by adding stacking blocks. However, the addition of stacking blocks requires a lot of manpower and time, which will delay the response time when floods come. Secondly, the stacking blocks are not well sealed after installation, which can easily lead to leakage and blockage, thereby reducing the flood discharge efficiency.

[0005] Based on this, the utility model designs a flood diversion and discharge device for water conservancy projects to solve the above problems. Utility Model Content
