A telescopic double-impeller pipeline power generation device

Abstract

The invention discloses a telescopic double-impeller pipeline power generation device, which respectively includes a water turbine unit, a power generation control unit, an impeller protection unit, an electric valve and a storage battery. The water turbine unit is composed of a telescopic sleeve and an impeller. The sleeve is equipped with two impellers, and the two water wheels rotate independently; the impeller protection unit, the main body is a cylindrical inner shell, and the connecting part of the inner shell and the pipeline is equipped with an electric opening and closing door: power generation control The unit includes a gear speed increaser box, a permanent magnet generator, a rectification circuit, and a control system; the control system is connected to the storage battery, and supplies power to and controls other electric components. In view of the problems that the hydro turbine unit is in pipeline operation for a long time in the traditional pipeline power generation, resulting in large loss of pipeline water head, water pollution and pipeline blockage, the device adopts a double-impeller retractable pipeline power generation device, and realizes the intermittent operation of the power generation device by controlling various parts of the system , to ensure the long-term stable operation of the power generation device.

Description

technical field [0001] The invention relates to the technical field of pipeline power generation, and more specifically, relates to a scalable double impeller pipeline power generation device. Background technique [0002] With the continuous development of Internet of Things technology, the urban water delivery network has higher and higher requirements for pipeline water delivery, and various water supply pipelines are gradually realizing intelligent control. However, the power supply problem of pipeline sensors limits its further development. Generally, water supply pipes are mostly buried underground and widely distributed, making it difficult to supply power through traditional wiring methods. At present, most of the flowmeters, pressure sensors and other data acquisition equipment, communication equipment and control equipment installed on the water pipe network use batteries for power supply. However, the capacity of traditional batteries is limited, and they need t...
