Standing before you is the \u5012\u8679\u5438\u8fdb\u6c34\u53e3. It is more than just a water inlet. It is an engineering marvel.
Let’s delve into the purpose of the \u5012\u8679\u5438\u8fdb\u6c34\u53e3. It relates to ecological discharge. This discharge needs no newly built bottom hole inlets. The \u5012\u8679\u5438\u8fdb\u6c34\u53e3 provides ecological water downstream.
The \u5012\u8679\u5438\u8fdb\u6c34\u53e3 makes use of an inverted siphon system. This design overcomes the dam. It discharges water to the downstream river.
Imagine water flowing through a steel pipe. This pipe is a key component. The steel pipe closely adheres to the dam’s water surface. The pipe has vertical and horizontal sections. These sections ensure effective water flow.
This system uses atmospheric pressure. It uses the pressure difference with a vacuum. This removes the need for continuous pumping. It creates an energy-saving discharge system.
The \u5012\u8679\u5438\u8fdb\u6c34\u53e3 includes an inlet horn. This horn is welded to the steel pipe. Support rings and waterstop rings reinforce the structure. They add to its stability and durability.
The design incorporates air intake and water filling pipes. These are located above the horizontal section of the steel pipe. They help regulate water flow. An ultrasonic flow meter monitors the water. An electric butterfly valve controls it. Pressure gauges and transmitters provide real-time data. They allow for precise operation.
Consider how the system starts. First the downstream electric butterfly valve closes. Then the underwater sewage pump starts. Water fills the steel pipe through the water filling pipe. Once full the air vent valve closes.
Next the downstream electric butterfly valve opens. Gravity pulls the water towards the lower end. This creates negative pressure in the steel pipe. Water from the reservoir is drawn into the inlet due to atmospheric pressure. This creates a continuous flow.
This ingenious design requires no manual control. It is a self-flowing ecological discharge system. It harnesses atmospheric pressure. It creates a vacuum. The \u5012\u8679\u5438\u8fdb\u6c34\u53e3 provides ecological benefits. It is also energy efficient.
The \u5012\u8679\u5438\u8fdb\u6c34\u53e3 showcases modern engineering. It provides ecological water downstream. It uses existing dam infrastructure. This reduces construction costs. It minimizes environmental impact. It represents innovation. It offers a sustainable approach to water management.
