Description

A variety of clean energy combined power generators

technical field

The utility model relates to a generator, in particular to a generator which adopts multiple clean energy sources to generate power together.

Background technique

Currently used wind generators are generally generators utilizing large wind power. For example, the large-scale wind turbines on Lamma Island in Hong Kong have the advantages of large torque, large rotational force, and high power; the disadvantage is that the wind speed requires more than 6 meters per second, and the use is limited. There are other wind generators with a power of 10KW. The advantage is that it can use the medium and small wind speeds that blow the most, and can automatically adjust the windward angle to improve the utilization rate of wind energy. The disadvantage is that the torque is relatively small and the power is small.

But the area that blows 3 meters per second or above wind is wide on the earth, and there are many days, the small wind of this wind speed can't be utilized by big wind-driven generator. And the natural wind is sometimes strong, sometimes small, sometimes not, which makes the continuity of the wind generator rotation poor. Moreover, the current function of automatically adjusting the windward angle is only suitable for small wind turbines. When the diameter of the wind rotor is slightly larger, the wind rotor will swing when rotating, resulting in poor typhoon resistance of the generator and a high failure rate.

Detailed ways

The preferred embodiments of the present utility model are described in detail below in conjunction with the drawings.

The overall structure of the various clean energy combined power generators in a preferred embodiment of the present invention is shown in Figure 1, and referring to Figures 2 and 3 at the same time, the multiple clean energy combined power generators include a wind wheel 10 and a connecting wind wheel The generator 13 of 10 is used to convert the rotational force of the wind wheel 10 into electrical energy. The wind wheel 10 is composed of a plurality of wind blades 11 and a rotating shaft 12, and the wind blades 11 can rotate around the rotating shaft 12 under the action of wind force. An electromagnet 14 and a cutting coil 15 are arranged on one end of each blade 11 that radiates outward (that is, the end away from the rotating shaft). N permanent magnets 20 are evenly arranged on the lower half circumference of the rotation diameter of the wind wheel 10 , and the magnetic field directions of the N permanent magnets 20 are alternately arranged, wherein N is an even number greater than or equal to 2.

As shown in Figure 3, when the wind blade 11 is driven by the wind to rotate, the cutting coil 15 on the wind blade 11 cuts the magnetic force lines of the permanent magnet 20, and an induced current is supplied to the electromagnet 14 coil on the adjacent wind blade 11 to generate induction. electromotive force. As the wind blade 11 continues to rotate, since the magnetic field directions of the N permanent magnets 20 on the lower half circumference of the wind wheel 10's rotation diameter are arranged alternately, when the cutting coil 15 moves to the magnetic field of different permanent magnets 20, the magnetic lines of force in different directions are cut , so that the magnetic poles of the electromagnet 14 also change accordingly, and generate an interaction force with the magnetic field of the corresponding permanent magnet 20, and use the magnetic field force to push the wind blade 11 to rotate, so that the wind wheel 10 can rotate even in the case of a small wind To generate electricity, the wind rotor can continue to rotate even when the outside wind is intermittent.

Since the monsoons on the earth mostly change in positive and negative directions or approximately positive and negative directions, the shape of each magnetic field and wind blade designed by this machine can adapt to the changes in the monsoon, which can further enhance the anti-typhoon ability of the machine. Taking the value of N as 10 and four wind blades 11 arranged centrally symmetrically with the rotation axis 12 as the center of symmetry as an example, the situation that the wind blades 11 are subjected to magnetic force will be analyzed and explained below.

As shown in Figure 2, the four wind blades 11 include the first wind blade 111, the second wind blade 112, the third wind blade 113 and the fourth wind blade 114. Ten permanent magnets 20 are respectively arranged on the rotation diameter of the wind wheel 10 Positions of 0°, 20°, 40°, 60°, 80°, 100°, 120°, 140°, 160°, 180° of the lower half circle.

The current generated by the cutting coil 15 on each wind blade 11 is only supplied to the coils of the electromagnets 14 on two adjacent wind blades 11 . As shown in Figure 3, current line a is the electromagnet 14 coils that the cutting coil 15 from the 4th wind blade 114 produces for the electromagnet 14 coils of this wind blade (being the first wind blade 111), and current line b is this wind blade ( That is, the induced current produced by the cutting coil 15 of the first wind blade 111) is for the second wind blade 112 and the fourth wind blade 114, and the current line c is for the induced current produced by the cutting coil 15 from the second wind blade 112 for the wind blade (that is, the coil of the electromagnet 14 of the first wind blade 111).

The magnetic force f experienced by each wind blade 11 can be expressed by the following formula:

$\mathrm{<span\; class="notranslate">\; f</span>}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; mm</span>}}^{<span\; class="notranslate">\; \&prime;</span>}}{\mathrm{<span\; class="notranslate">\; 4</span>}\mathrm{<span\; class="notranslate">\; \&pi;</span>}{\mathrm{<span\; class="notranslate">\; \&mu;</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}{\mathrm{<span\; class="notranslate">\; r</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 6.3</span>}<span\; class="notranslate">\; \&times;</span>{\mathrm{<span\; class="notranslate">\; 10</span>}}^{\mathrm{<span\; class="notranslate">\; 4</span>}}<span\; class="notranslate">\; \&times;</span>\frac{{\mathrm{<span\; class="notranslate">\; mm</span>}}^{<span\; class="notranslate">\; \&prime;</span>}}{{\mathrm{<span\; class="notranslate">\; r</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span>$

In the above formula (1), m represents the magnetic charge of the permanent magnet, m' is the magnetic charge of the electromagnet, and r is the distance between the electromagnet and the permanent magnet.

Wherein, when the permanent magnet 20 used is selected, m is a constant, while m' and r are variables when the wind wheel rotates, these three parameters together determine the size of f. And the size of f is proportional to mm' and inversely proportional to ^r2 . Therefore, what the wind wheel 10 is subjected to is a constantly changing, regular, and cyclic magnetic field force, which can be decomposed into a rotational force along the tangential direction of the rotation circle of the wind wheel 10 and an upward magnetic levitation force to the wind wheel 10. force, and jointly promote the rotation of the wind wheel 10.

When the second wind blade 112 shown in Fig. 2 moves from point C to point C', when the position of point C is f=100N, m=169×10 ^-3 , m'=6×10 ^-3 , other points The magnetic field force f of the position is shown in Table 1 below.

Table 1 Analysis of the stress on the second wind blade from point C to point C'

The total force f' at each point is shown in Table 2 below.

Table 2 The total force on each point of the second wind blade from point C to point C'

Location C B A 0 A' B' C'

The sum of the forces 2×(100+100) 2×(200+20) 2×(400+0) →0 2×(400+0) 2×(200+20) 2×(100+100) total f' 400N 440N 800N →0N 800N 440N 400N

When the wind wheel 10 rotated to the position shown in Figure 2, the cutting coils 15 of the first wind blade 111 and the third wind blade 113 were cutting the magnetic lines of force of the permanent magnet 20, generating an induced current, and the two induced currents flowed through the first wind blade simultaneously. The electromagnet 14 coils on the two wind blades 112 produce an induced magnetic field, and the front end of the induced magnetic field is a positive pole, and the rear end is a negative pole. One front end of the two magnetic fields of adjacent permanent magnets 20 is a positive pole, and the rear end is a negative pole. The front end is the negative pole, and the back end is the positive pole. According to the principle that same-sex magnetic charge repels each other and opposite-sex attracts each other, the second wind blade 112 receives repulsive force and suction force at points C and C', and suction force at points B and A, and points A' and B' What is received is mainly repulsive force, so that the wind wheel 10 can continue to rotate.

When the second wind blade 112 shown in Fig. 2 rotates to point C, it is at the position of the weakest magnetic field, cutting the magnetic field line produces a weak current, and the weak current is supplied to the adjacent first wind blade 111 and the third wind blade 111 at the same time. The electromagnet 14 coils on the blade 113, and the electric current of the cutting coil 15 on the second wind blade 112 approaches 0, the electromagnet coil current on the wind blades 111 and 113 also approaches 0, and the magnetic field force also approaches 0, It can ensure that the wind blades 111 and 113 pass through the dead point of the magnetic field smoothly, and ensure the continuous rotation of the wind wheel 10 .

In this embodiment, the material for making the electromagnet 14 is a silicon steel sheet.

根据能量守恒定律，切割阻力应与m’x相同，即阻力为

从理论上看，控制m’，就可以控制切割阻力的大小。Next, the resistance generated by the cutting coil 15 on the wind blade cutting the magnetic force lines of the permanent magnet 20 will be analyzed. If the magnetic charge ratio between m and m' is 100:1, that is, m:m'=100:1, since the magnetic field force is determined by the magnetic charge, then mx:m'x=100. Since f=mx+m'x, f=100m'+m', m'

According to the law of energy conservation, the cutting resistance should be the same as m'x, that is, the resistance is

Theoretically, by controlling m', the cutting resistance can be controlled.

Preferably, as shown in FIG. 4 , the cross section of the wind blade 11 is designed in a shape in which both ends of a straight line bend in opposite directions. When the wind blows, the curved position of the wind blade 11 holds the wind, which slows down the flow velocity of the air on the front surface of the wind blade 11, while the back of the wind blade 11 is negative pressure, and the curved position cannot hold the wind, but flows through it. The entire curved surface increases the air velocity at the back, forming a large pressure difference between the front and back of the wind blade, improving the utilization factor of wind energy and improving the power generation efficiency.

Since the monsoons on the earth mostly change in positive and negative directions or approximately positive and negative directions, the use of wind blades with cross-sections that are curved in opposite directions at both ends of a straight line segment can adapt to wind forces that change in positive directions, reverse directions, or large angles. The rigidity and stability when the wind wheel 10 rotates can be improved, and the anti-typhoon ability of the generator can be enhanced. More preferably, a plurality of vent holes 16 are arranged on the busbar of the curved part on the wind blade 11, the wind on the front of the wind blade 11 will pass through the vent holes 16, and produce a reaction force to the wind blade 11, so that the wind blade 11 remains stable and balanced; When the wind blows in the opposite direction, the vent hole 16 can also play the role of stabilizing balance. The number and arrangement of vent holes 16 can be designed according to needs, for example, in areas with more typhoons, wind blades 11 with more vent holes 16 can be used.

In order to make the wind rotor 10 rotate with a greater thrust, the size of the wind blade 11 is generally designed to be larger, preferably 10-30m ² , more preferably 20m ² , in order to increase the force-bearing area and increase the force received by the wind rotor 10. The thrust allows it to take advantage of the medium and low-speed winds that blow most on the earth, making up for the shortcomings of existing wind turbines. Of course, the size of the wind blade 11 is not limited thereto, and can be manufactured according to the actual conditions of the area where it needs to be used.

Preferably, as shown in Figure 1, the multiple clean energy combined power generator of this embodiment also includes a solar panel 30 that converts solar energy into electrical energy, and the solar panel 30 is connected to the permanent magnet 20 through a storage battery 31 for providing permanent magnets. The magnet 20 is magnetized to make full use of natural clean energy to ensure the continuous and effective operation of multiple clean energy synergy generators.

Preferably, the multi-clean energy combined power generator also includes a centrifugal force switch, which is used to cut off the current of the coil of the electromagnet 14 on each wind blade 11 when the natural wind speed exceeds a predetermined value. For example, when the wind speed exceeds 12 m/s, that is, when the natural wind speed is large enough, the centrifugal force switch cuts off the current of the coil of the electromagnet 14, so that m'→0, and the magnetic field force f→0 received by the wind blade 11 at each position, At this moment, the wind wheel 10 can be driven to rotate by natural wind force alone.

When utilizing the force of the earth's magnetic field, it is preferable to use conductive fibers to make each wind blade 11 of the wind wheel 10. The magnetic flux density of the earth's magnetic field is very low, and an induced electromotive force of several volts to more than ten volts can be generated in the wind blade 11 for power generation. The exciting coil reduces the resistance of the strong magnetic field when starting.

It should be noted that the number of wind blades 11 of the wind rotor 10 and the number of 20 permanent magnets on the lower half circle or the entire circumference of the wind rotor rotation diameter are not limited to those listed in the above embodiments, and can realize the present invention. Any number of utility model purposes. And the analysis data of the magnetic field force of the wind blade listed in the above embodiments is only an example, the real force data is different according to the different sizes of wind wheels manufactured, and the nature and arrangement of the different permanent magnets selected. Not limited by the above examples.
