Abstract

The invention discloses an electric energy and pipe interior fluid kinetic energy conversion device, and belongs to the technical field of motors. The electric energy and pipe interior fluid kinetic energy conversion device is invented for simplifying a structure and reducing the fault rate. The electric energy and pipe interior fluid kinetic energy conversion device comprises a motor and a fluidmachine. The motor is provided with a rotor and a stator. The fluid machine comprises rotation blades (2) and a rotation shaft (3) of the rotation blades (2). The electric energy and pipe interior fluid kinetic energy conversion device is characterized in that the rotor and the rotation blades are mutually fixedly arranged in a pipe; and the position, corresponding to the rotor, of the stator anda pipeline (1) are positioned and installed outside the pipe. A bearing between the rotation shaft of the rotation blades and the pipeline is a magnetic suspension bearing. A permanent magnet is fixedly arranged on the outer edge part of the rotation blades, so that the rotor is formed. The stator can be dismounted along the generatrix.

Description

technical field [0001] This patent application relates to motors (including motors and generators), in particular to a conversion device for electric energy and fluid kinetic energy in a tube. In one conception, its application field is natural convection power generation in a low temperature difference environment. Background technique [0002] Taking the electric pipeline axial flow pump as an example, the common structure of the electric pipeline axial flow pump is that the rotor and stator of the motor are outside the pipeline, and the impeller is inside the pipeline. The mechanical energy output by the motor is transmitted to the impeller through the transmission mechanism. The structure requires frequent maintenance. Contents of the invention [0003] The purpose of this patent application is to provide a conversion device for electric energy and fluid kinetic energy in the pipe, which can greatly reduce the failure rate and maintenance frequency. [0004] This obj...
