Abstract
The utility model discloses a repulsion force friction reducing device of a windmill. A magnetic ring with brute force is sheathed on a rotary shaft of windmill blades, and a semicircular magnetic body is arranged below the corresponding magnetic ring. An outer ring of the magnetic ring and an inner ring of the semicircular magnetic body have the same magnetic polarity. The semicircular magnetic body is fixed to a supporting frame. Because the magnetic ring is arranged on the blade shaft of a windmill, the semicircular magnetic body is arranged below the blade shaft of the windmill and one surface of the magnetic ring and one surface of the semicircular magnetic body, which faces the surface of the magnetic ring, have the same polarity; the repulsion force generated by the same polarity is used for supporting the rotary shaft of the windmill, thereby, the frictional force under the condition of the rotation of the windmill is decreased and the conversion efficiency of the windmill is improved.
Description
Technical field
The utility model relates to the device that a kind of windmill is reduced friction, particularly a kind of device of reducing friction by the repulsive force of magnetic force.
Background technique
Because wind energy is pollution-free, low cost and other advantages, the utilization of wind energy more and more is subjected to people's attention.Existing Wind Power Utilization device generally all is to be mechanical energy by windmill with wind energy transformation, and then utilizes direct mechanical can or mechanical energy be converted into electric energy, so windmill is the most crucial parts that utilize wind energy.
When windmill is set, windmill must be set to certain height, and because the huge blade of windmill can produce bigger gravity, the existence of this gravity will produce bigger frictional force, and this frictional force can consume bigger energy, thereby reduce the transformation efficiency of windmill, also can influence the working life of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of windmill repulsion antifriction apparatus, and it can effectively overcome the existing low defective of windmill transformation efficiency.
Windmill repulsion antifriction apparatus of the present utility model is a sheathed powerful magnet ring in the air vane rotating shaft, and semicircle magnet is set below corresponding magnet ring, the interior ring of the outer shroud of magnet ring and semicircle magnet has identical magnetic polarity, and semicircle magnet is fixed on the support.
Above-mentioned device also comprises column, and an end of rotating shaft is arranged on the column by bearing, and support also is fixedly installed on the column.
The length of described semicircle magnet is greater than the length of magnet ring, and the thickness of semicircle magnet is greater than the thickness of magnet ring.
Described semicircle magnet axis and magnet ring axis are not parallel, and an end of close air vane is a little more than the other end.
The axis of described semicircle magnet and magnet ring axis are 20 degree angles.
Because the utility model is to be provided with magnet ring on the sharf of windmill, and semicircle magnet is set thereunder, magnet ring has identical polarity with semicircle magnet one side in opposite directions, hold up the rotating shaft of windmill with the repulsive force of this identical polar generation, thereby reduce the windmill frictional force in when running, can improve the transformation efficiency of windmill.
Description of drawings
Fig. 1 is the structural representation of windmill repulsion antifriction apparatus of the present utility model;
Fig. 2 is magnet ring of the present utility model and magnet arrangement schematic representation.
Embodiment
As shown in Figure 1, windmill repulsion antifriction apparatus of the present utility model is that the main shaft 2 at windmill is arranged with powerful magnet ring 3 near on the positions of blade 1, and the other end at main shaft 2 is provided with column 6 simultaneously, this end of rotating shaft 2 by bearing fixing on column 6.Below the position of corresponding and magnet ring 3, the magnet 4 of semi-circular cross-section is set, this magnet 4 is fixed on the support 5, and 5 on support is fixed on the column 6.
As shown in Figure 2, the inner ring surface of semicircle magnet has identical polarity with the outer ring surface of magnet ring, thereby can between magnet ring and semicircle magnet, produce magnetic repulsion force, under the effect of this magnetic repulsion force, the main shaft 2 of windmill is upwards held up, thereby can reduce windmill frictional force in the running, improve the utilization ratio of wind energy.
As shown in Figure 1, because the weight of windmill is mainly produced by air vane, so semicircle magnet slightly upwards can be carried near an end of blade, be formed axis and the uneven state of magnet ring axis, the so better effect of equilibrium magnetism repulsion of semicircle magnet.In the present embodiment will and the angle of axis be made as 20 the degree.
As shown in Figure 1, 2, be to improve the effect of repulsion, the length greater than magnet ring that the length of semicircle magnet can be provided with, the thickness that the thickness of semicircle magnet is provided with simultaneously greater than magnet ring.
The utility model is a principle of utilizing the magnetic substance same sex to repel each other, the power of reducing friction after main shaft is held up by magnetic force.
