Description

Technical Field

[0001] The invention belongs to the technical field of power generation devices, and in particular relates to a power generation device utilizing water flow in a pipe. Background Art

[0002] A power generation device that uses water flow in a pipe is a device that converts the kinetic energy of water flow into electrical energy. It is a type of hydroelectric power generation. This device is usually installed inside a pipe and can use the natural flow of water in the pipe to drive a turbine or other mechanical devices to generate electrical energy. The working principle of this power generation is to use the flow rate of the water body to drive the blades to rotate, and convert the mechanical energy of the blade rotation into electrical energy. This conversion is based on the law of electromagnetic induction, that is, when a conductor cuts the magnetic lines of force in a magnetic field, an electromotive force will be generated in the conductor. If the conductor forms a closed loop, an electric current will be generated. The conversion is mainly composed of two parts: the stator and the rotor. The rotor rotates in the magnetic field and cuts the magnetic lines of force in the stator, thereby inducing an electromotive force in the stator winding and outputting electrical energy through an external circuit.

[0003] This type of power generation device is mainly used in urban water supply systems. It uses the water flow in the tap to generate electricity and provide power for low-power terminal devices such as smart water meters and induction faucets. It can also use the water flow in the pipe to generate electricity in the industrial production process to provide power for the production line. It can also be used in water conservancy projects to use the water flow in rivers or reservoirs to generate electricity and provide electricity to surrounding areas. This type of power generation method is environmentally friendly and energy-saving. It uses natural water flow to generate electricity, does not consume fossil fuels, and reduces environmental pollution. Compared with traditional thermal power generation, power generation devices that use water flow in pipes are cheaper and easier to install. They can be directly installed in existing pipeline systems without the need for additional infrastructure construction. However, in actual applications, the water flow velocity inside the water pipe is low and the power generation efficiency is low, especially in flat pipes. Therefore, the water flow velocity should be considered in the design to improve power generation efficiency and increase power generation capacity. Summary of the invention
