Abstract
Description
Technical Field
[0001] The present invention relates to the field of magnetic levitation technology, and in particular to a magnetic levitation hybrid engine. Background Art
[0002] Magnetic levitation technology (English: electromagnetic levitation, electromagneticsuspension, referred to as EML technology or EMS technology) refers to a technology that uses magnetic force to overcome gravity to suspend an object; there are many forms of magnetic levitation technology, which can be mainly divided into passive suspension with self-stabilization of the system and active suspension with inability to stabilize the system. The first magnetic levitation car was developed by Japan. A rotating engine was installed in the middle of all the wheels of the magnetic levitation car, and two magnets were installed on the outside of the wheels; when the wheels rotate, the magnetic field on the magnetic levitation road surface changes, generating induced current, and the magnetic field of the magnetic levitation road surface interacts with the magnets on the wheels to generate buoyancy and driving force; the size of the tested miniature magnetic levitation car model (52cm×23cm×14cm), weighing 4kg, was successfully carried out in a driving test on a straight distance of 26m, with a speed of 25km per hour, and the car model was suspended 6 to 7mm from the magnetic levitation road surface. In 2014, Hendo invented the Hoverboard magnetic levitation skateboard. The Hoverboard magnetic levitation skateboard is equipped with four disc levitation engines at the bottom. The engines are equipped with miniature neodymium magnet discs controlled by DC motors. After starting the DC motor, the high-frequency alternating magnetic field generated by the rotation of the neodymium magnet discs is used to generate an induced magnetic field repulsion force on the non-magnetic metal ground, thereby achieving a magnetic levitation effect and allowing the skateboard to float 2.54 cm above the ground. However, the above-mentioned magnetic levitation engine has a complex structure, a high cost, and an unsatisfactory levitation height. It is too close to the ground and is easily adsorbed by metal objects such as iron blocks on the bottom. Summary of the invention
[0003] The purpose of the present invention is to provide a magnetic levitation hybrid engine, which can monitor in real time whether the screen machine is working normally, so as to prevent the failure of sewage treatment due to the operator's failure to find the damage of the screen machine in time.

Furthermore, it can also make the device carrying the engine suspend higher, reducing the impact of ground magnetic objects on the device carrying the engine; further, the rotating high-frequency alternating magnetic field generated by the twelve groups of electromagnets installed in the electromagnet mounting seat under the action of currents of different phases will generate an induced magnetic field repulsion force on the magnetic levitation road surface, thereby achieving a magnetic levitation effect; the setting of the electromagnet replaces the traditional neodymium magnet, effectively reducing the production cost.
