Description

Technical Field

[0001] The utility model belongs to the technical field of water turbines, and in particular relates to a bidirectional water turbine device. Background Art

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery among fluid machinery. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, water from the upstream reservoir is led to the water turbine through a water diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has completed the work is discharged downstream through the tailwater pipe. The higher the water head and the greater the flow rate, the greater the output power of the water turbine.

[0003] Aquatic animals and plants can easily enter the turbine inlet, which can negatively impact the turbine's operating efficiency and aquatic ecosystem. For example, Chinese patent application number 202323068168.X discloses a turbine designed for easy assembly and disassembly. This mechanism allows the outlet pipe to be tightly connected to the external pipe when the turbine is in use, enabling efficient operation. It also allows for quick assembly and disassembly of the outlet pipe, improving debris removal efficiency. However, the turbine lacks a filtering function, making it easy for aquatic animals and plants to enter, impacting normal operation.

[0004] It is desirable to provide an improved bidirectional water turbine arrangement. Utility Model Content
