Description

Technical Field

[0001] The utility model relates to the field of magnetic isolation, and more specifically, to a magnetic isolation plate. Background Art

[0002] In most of the prior art, mechanical energy is generated by converting the attraction and repulsion between two permanent magnets of the same volume, thereby replacing the loss of coal, electricity and fuel and reducing energy consumption. However, when the attraction and repulsion between the two permanent magnets are used, the magnetic poles of the two permanent magnets of the same volume remain unchanged. In certain scenarios, the two permanent magnets need to be brought close to each other. Since the repulsion of the permanent magnets always exists, the repulsion and the mechanical energy generated when the permanent magnets are close to each other will cancel each other out.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a magnetic isolation plate, which can isolate the repulsive force of two permanent magnets to a large extent by arranging a magnetic conductive layer and an anti-magnetic layer, thereby allowing the two permanent magnets to approach quickly without the repulsive force between the permanent magnets offsetting the converted mechanical energy.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a magnetic isolation plate, comprising a supporting layer, a magnetic conductive layer and an anti-magnetic layer arranged in sequence, wherein a nanolayer for mutual bonding is arranged between the supporting layer, the magnetic conductive layer and the anti-magnetic layer, and the weight and volume ratio of the magnetic conductive layer and the anti-magnetic layer to the weight and volume of the required blocking magnetic block is 0.2-0.5:1.

[0013] The utility model is further configured as follows: the contents of titanium, magnesium, tin and zinc in step 3 are: 12%-22% titanium, 4%-8% magnesium, 5%-7% tin and 2% zinc.

[0014] The utility model is further configured as follows: the support layer accounts for 48%-54%, the magnetic conductive layer accounts for 12%-20%, and the antimagnetic layer accounts for 34%-42%.

[0015] In summary, the utility model has the following beneficial effects:

[0016] The magnetic field of the permanent magnet is guided and blocked by the magnetic conductive layer and the anti-magnetic layer, thereby reducing the magnetic field of the two permanent magnets, so that the magnetic isolation plate can weaken the repulsion between the two permanent magnets during the process of converting mechanical energy, so that the repulsion is reduced when the two permanent magnets are close to each other. The weight ratio of the magnetic conductive layer and the anti-magnetic layer to the volume of the required blocking magnetic block is 0.2-0.5:1. When the magnetic isolation plate is in effect, the ratio of the magnetic isolation plate to the volume of the magnet can well weaken the repulsion between the two permanent magnets.
