Description

Technical Field

[0001] The utility model relates to the technical field of drain devices, and more specifically, to a drain device used in water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. On dams and riverbanks, the water level rises due to flood conditions. The water level will reach the warning level of the dam and the river bank, but sometimes for the sake of the downstream and outside the river bank, the dam and the river bank cannot be opened to discharge flood water, resulting in more and more water in the dam and the river bank, making the pressure on the dam body and the river bank greater and greater. People usually use water pumps to pump out the water in the dam body and transport it to other places through pipes to reduce the pressure on the dam body. However, the use of water pumps not only consumes a lot of electricity, but also cannot be used when there is a power outage during the flood season, resulting in the inability to drain water. Therefore, how to propose an energy-saving drainage device suitable for dams and river banks is particularly important. In view of this, we propose a drainage device for water conservancy projects.
