[0003] At present, the application of energy recovery in the field of rotating machinery is also relatively extensive. For example, in order to understand the operating health status of rotating machinery, a monitoring system is usually embedded in the machinery to monitor the operating status of rotating machinery, and the detection system requires an external power supply or a battery. Power supply, the wiring is difficult, and it is inconvenient to replace the battery. It has become a popular development direction to use the energy recovered from the rotating machinery to power the detection system; the current energy recovery method is usually mechanical, and the rotation of the rotating machinery drives other mechanical parts to move. Energy recovery, this type of recovery device has a complex structure and low energy recovery efficiency

Embodiment Construction
[0023] figure 1 It is a schematic diagram of the explosion structure of the present invention; figure 2 It is a schematic diagram of the plane structure; image 3 for figure 2 Schematic diagram of radial section structure;
[0024] This embodiment provides a rotational energy recovery device based on the principle of electromagnetic induction, which includes an outer ring assembly and an inner ring 1 located inside the outer ring assembly. It is installed in the outer ring assembly in a manner of rotating along its own axis. A coil 2 is fixed inside the outer ring assembly. A magnet 3 is connected to the side of the inner ring axially close to the coil. When the outer ring assembly rotates relative to the inner ring assembly Electric energy is generated by changing the magnetic flux through the coil; combined with figure 1 As shown, the magnet is preferably a permanent magnet. In this embodiment, the permanent magnet is made of NdFeB; the permanent magnet made of this ma...

The invention discloses a rotating energy recovery device based on the principle of electromagnetic induction, which includes an outer ring assembly and an inner ring located in the outer ring assembly, the inner ring and the outer ring assembly are coaxially arranged and can be positioned along the outer ring assembly relative to the outer ring assembly. It is installed in the outer ring assembly in the way of axial rotation. The inner side of the outer ring assembly is fixed with a coil. The side of the inner ring axially close to the coil is connected with a magnet. When the outer ring assembly rotates relative to the inner ring assembly, the magnetic flux passing through the coil Changes to generate electric energy; the energy recovery device of the present invention has no intermediate mechanical transmission parts, simplifies the intermediate transmission link, and avoids energy loss in the intermediate transmission link. Poor energy recovery.
Description
technical field [0001] The invention belongs to the technical field of energy recovery, in particular to a rotating energy recovery device based on the principle of electromagnetic induction. Background technique [0002] With the gradual strengthening of environmental protection awareness, energy recovery has attracted more and more attention from various disciplines and application fields. Energy recovery is to convert energy forms that cannot be stored and reused, such as thermal energy, mechanical energy, light energy, etc., into electrical energy for storage. Utilization; such as solar energy recovery, vehicle braking energy recovery, geothermal energy recovery, etc.; [0003] At present, the application of energy recovery in the field of rotating machinery is also relatively extensive. For example, in order to understand the operating health status of rotating machinery, a monitoring system is usually embedded in the machinery to monitor the operating status of rotatin...
