Hydroelectric Generation
★Exhibit Content: Hydroelectric Power Generation ★Interaction: Mechanical Interaction ★Operation: Turn the handwheel and observe the change of the ammeter. ★Exhibit Description: The exhibit mainly consists of a display stand, a glass water tank, and a power generation indicator device, demonstrating the working principle of hydroelectric power generation to the audience. Through the rotation of the water turbine, the exhibit realizes the conversion of mechanical energy into electrical energy. ★Scientific Principle: The audience turns the handle, driving the waterwheel to carry water from the lower tank to a higher level. The water gains potential energy and flows downward, doing work on the generator blades, driving the generator rotor to rotate. The rotor cuts the magnetic lines of force, generating an induced electromotive force and an induced current, which makes the ammeter swing. This is the basic principle of hydroelectric power generation. In practical applications, hydroelectric power generation converts the potential energy of water into mechanical energy of the waterwheel, and then uses the mechanical energy to drive the generator, thereby obtaining electricity. Hydroelectric power is a renewable energy source with minimal environmental impact.

★Exhibit Content: Hydraulic Energy Conversion, Comparison of Three Typical Water Turbine Working Principles ★Interaction: Electromechanical Interaction ★Operation: 1. Operate the water pump to fill the upper tank; 2. Open the corresponding valve to direct water flow to different water turbines; 3. Observe the power meters and compare the power generation efficiency of different water turbines. ★Exhibit Description: This exhibit mainly consists of a display cabinet, upper tank, lower tank, water supply pump, Pelton turbine, Francis turbine, Kaplan turbine, pipeline valves, and power display meters. It is a recommended exhibit from the KexMall exhibit mall. Visitors operate the exhibit's water pump to lift water from the lower tank to the upper tank, using the water level difference to form a water flow. By switching valves, the water flow impacts three different types of water turbines, which drive generators to output electrical energy. The meters display the corresponding power generation in real time. Through comparable physical models, the exhibit intuitively presents the energy conversion process of hydroelectric power generation. Visitors can directly see the performance differences of different water turbines under the same water flow conditions and understand the hydraulic conditions suitable for different water turbines. It is suitable for energy science education experiences. ★Scientific Principle: Hydroelectric power generation converts the gravitational potential energy of water into mechanical energy, which then drives a generator to convert it into electrical energy. The Pelton turbine relies on jet impact on bucket-shaped blades, suitable for high-head, low-flow conditions; the Francis turbine uses both water pressure and kinetic energy to do work, suitable for medium-head, medium-flow scenarios; the Kaplan turbine relies on adjustable-angle blades, suitable for high-flow, low-head conditions. The structural differences of the three turbines lead to differences in energy utilization efficiency. Through meter readings, the energy conversion effects of different turbines can be intuitively compared, helping to understand the basic physical logic of hydropower station selection and design.
