Pipeline power generation micro hydraulic turbine set

Abstract

The invention discloses a pipeline power generation micro hydraulic turbine set. The pipeline power generation micro hydraulic turbine set comprises hydraulic turbine set units located inside and outside a pipeline, and a power generation rectification unit. Each hydraulic turbine set unit is composed of a spindle and at least two impellers, wherein the spindle is connected with the impellers, theimpellers and the spindle are in clearance fit, and the flow incident faces of the impellers are perpendicular to the inflowing direction so that the impellers can rotate to drive the spindle to rotate. At least two spindles are arranged in the pipeline. The power generation rectification unit comprises a gear speed-increasing box, a permanent magnet generator and a rectification circuit. Bearings for positioning the spindles are arranged in the positions where the spindles penetrate through the outer wall of the pipeline, and sealing rings are arranged between the bearings and the gear speed-increasing box and used for preventing liquid from entering the permanent magnet generators. According to the pipeline power generation micro hydraulic turbine set, aiming at the problems of low power generation efficiency and poor stability of a single pipeline hydraulic turbine, the hydraulic kinetic energy is extracted through the hydraulic turbine set adopting an array distribution mode and converted into electric energy, and thus power storage and power supply to small-power electric facilities are achieved.

Description

technical field [0001] The invention belongs to the technical field of pipeline power generation, and in particular relates to a micro water turbine unit for pipeline power generation. Background technique [0002] As a common device for conveying liquids, pipeline devices are widely used in modern society. The pipeline system includes domestic water supply pipelines, sewage discharge pipelines, industrial water pipelines, and large-scale water pipeline projects. The pipelines contain objective energy, such as the flow of water, which has great kinetic energy. In today's situation of energy shortage and increasingly serious environmental pollution problems, the recycling and sustainable utilization of energy has become a hot spot in energy development. Fluid power generation has the advantages of no pollution and high utilization rate. The fluid in the pipeline contains considerable energy. If the energy can be reused instead of wasted, it is of great significance to the su...
