Problems solved by technology

[0006] However, the inventors have found that: on the one hand, at present, there is insufficient investment in the research of liquid metal magnetic fluid power generation technology, resulting in the lack of guidance for the design of liquid metal magnetic fluid power generation channels; on the other hand, for liquid metal magnetic fluid power generation The characteristic research experiments lack systematic and standardized experimental devices and devices, and the flexible experimental parameter conditions are also limited by the experimental devices, which cannot promote the research on the theory of liquid metal magnetic fluid power generation and the characteristics of power generation channels

[0041] second embodiment ,refer to image 3 and 4 , the power generation channel 14 is composed of an insulating channel plate 17, an intermediate insulating flange 18, a connecting flange 19, a transition flange 21 and an electrode 22. A pair of insulating channel plates 17 and a pair of electrodes 22 are connected by screws, forming a square shape in the middle When the liquid metal magnetic fluid flows through the channel, an induced electromotive force will be generated under the action of the magnetic field. The intermediate insulating flanges 18 are divided into two groups, which are symmetrically arranged at both ends of the electrode 22 . The connecting flange 19, the reducer pipe 20 and the transition flange 21 are sealed and fixed together sequentially. The transition flange 21, the intermediate insulating flange 18, and the insulating channel plate 17 are fixed together. A wiring hole 22a is opened on the outer end surface of the electrode, which is used for con...

[0043] third embodiment ,refer to Figure 5 , the magnetic gathering device 15 is a structure with a square through hole in the middle, the upper and lower opposite sides of the square through hole are respectively fixed with an N pole magnet 15c and an S pole magnet 15d, and the electrode 22 and the insulating channel plate 17 are arranged on the N pole. In the gap between the pole magnet and the S pole magnet.

[0044] The magnetic gathering device 15 of this structure can be replaced with magnets of different strengths, and the influence of different magnetic field strengths on the characteristics of the power generation channel can be studied. In addition, during installation, since the power generation channel and the magnet are a separate design, it is convenient to replace magnets of different strengths in the progress of subsequent experiments, and to study the influence of different magnetic field strengths on the characteristics of the power generation channel. The...
