Description

Power generation device and stator module

The present invention relates to a power generation device, and particularly to a power generation device and a stator module that can provide a large amount of power generation.

Most of the conventional power generators (for example: motors or generators) include a rotor module and a stator module. In addition, since the power generation amount is higher, all the conventional power generation devices tend to reduce the gap between the rotor module and the stator module. However, when the gap between the rotor module and the stator module is reduced, not only does the collision between the rotor module and the stator module easily occur, but in the configuration of the conventional power generator, the rotor module and the stator module It is not possible to have a gap of 0 (no gap). In view of this point, how to generate a larger amount of power generation by minimizing (for example: removing) the gap between the rotor module and the stator module under the assumption that the elements of the power generation device do not collide However, it became one of the issues that this area emphasizes.

Therefore, the present inventor considers that there is room for improvement of the above-mentioned drawbacks, particularly researches, and uses academic principles to finally improve the above-mentioned drawbacks reasonably and effectively. Created the present invention that can do things.

In this embodiment, it is necessary to explain the implementation method of the present invention concretely in correspondence with the related quantities and outlines that are discussed in the drawing. It is well understood, but does not limit the scope of the rights of the present invention.

As shown in FIGS. 1 to 3, this embodiment is a kind of power generation device 100, and in order to better understand the power generation device 100 of this embodiment, a power generation device of the following fluid (for example, wind power) is taken as an example. Explain, but not limited to this. That is, the power generation apparatus 100 of the present embodiment never excludes application to a generator or a motor. Among them, the power generation apparatus 100 includes one stator module 1 and one rotor module 2 attached in the stator module 1. The rotor module 2 can rotate with respect to the stator module 1. Thereby, the power generator 100 generates electric power. Hereinafter, the structures of the stator module 1 and the rotor module 2 will be described first, and then the correspondence between the stator module 1 and the rotor module 2 will be described.

2 and 3, the stator module 1 includes a casing 11 and a first magnetic guide module 12 installed on the casing 11. As shown in FIG. The casing 11 includes one elongated flow pipe 111 and both support portions 112. Among them, in the present embodiment, the flow pipe 111 is a circular pipe having a constant inner diameter, and has one flow passage 113 surrounded by the flow pipe 111. Further, the flow pipe 111 is defined as one axis L passing through the flow passage 113. The axis L corresponds to the center line of the flow pipe 111 in the present embodiment, but the present invention is not limited to this. Both the support portions 112 are installed in opposite sides of the flow pipe 111 (for example, the left and right sides of the flow pipe 111 in FIG. 1). The structure of all the support portions 112 is suitable for flowing a fluid (for example, wind) into and out of the flow passage 113.

The first magnetic guide module 12 includes several first magnetic guide units 121 and several flexible magnetic guide brushes 122. These first magnetic guide units 121 are distributed on the flow pipe 111 of the casing 11, and the quantity and density of the first magnetic guide units 121 distributed in the casing 11 are adjusted according to the demand of the designer. However, there are no particular restrictions here.

To put it one step further, all the first magnetic guide units 121 are connected to the core portions 1211 of both metals, the coils 1212 wound around the core portions 1211, and the core portions 1211, respectively. One guide part 1213 (for example: metal material, silicon steel plate, or iron plate) is included. Among them, the two core portions 1211 and the guide parts 1213 can be integrally connected or separated. In addition, all the first magnetic guide units 121 can be fixed to the flow pipe 111 of the casing 11 through the core portion 1211, and the central axis of all the core portions 1211 is one center which is substantially orthogonal to the axis L. It can be defined to be on line C.

The number of the flexible magnetic guide brushes 122 is approximately equal to the number of the core portions 1211 in the first magnetic guide module 12, so that one flexible magnetic guide brush 122 is installed in every core portion 1211. ing. That is, each of the flexible magnetic guide brushes 122 is mounted on the end of the core portion 1211 so as to be separated from the flow pipe 111 of the casing 11, and the flexible magnetic guide brush 122 is located in the flow passage 113. . Among them, in this embodiment, the flexible magnetic guide brush 122 is formed by arranging a plurality of flexible metal wires in parallel. Both ends of the flexible metal wire are defined as a fixed end and a free end, respectively. The fixed end of the flexible metal wire is fixed directly or indirectly on the corresponding core portion 1211, while the free end of the flexible metal wire has elasticity with the fixed end as a fulcrum. It can oscillate and does not damage the element (for example, the magnetic pole end 2211 of the magnet 221 described below) with which it can come into contact.

As shown in FIGS. 2 and 3, the rotor module 2 is rotatably installed in the flow passage 113 of the casing 11. Moreover, the rotor module 2 includes one rotating part 21 that rotates about the axis L and one first magnetic module 22 that is installed on the rotating part 21. Among them, the rotating part 21 includes one column body 211 and one spiral blade 212 connected to the outer edge of the column body 211. Both ends of the column body 211 are pivoted at the centers of both support portions 112 of the casing 11. In the present embodiment, the center line of the column body 211 overlaps the axis L. The edge of the spiral blade 212 is formed by indenting at least one storage tank 2121 (the radial direction is parallel to the center line C) along one radial direction of the vertical axis L. Further, the distance of the edge of the spiral blade 212 to the axis L is larger than the minimum distance to the axis L of the flexible magnetic guide brush 122 (that is, the distance between the free end of the flexible metal wire and the axis L).

In addition to this, the rotating part 21 shown in FIG. 3 is an example in which the spiral blade 212 is independently formed on the column 211, but this embodiment can also be adjusted and changed according to demand. . For example, as shown in FIG. 4, the rotating part 21 of the present embodiment can form a number of spiral blades 212 on the column body 211, and all the spiral blades 212 can be formed. The storage tank 2121 can be formed on a specific position according to a designer's request. Thus, the corresponding first magnetic force module 22 is provided for installation. In addition, the rotating part 21 is exemplified by the installation of the spiral blade 212. However, the rotating part 21 may be a non-spiral blade (not shown) such as a fan blade or a conventional generator or It is not excluded to adopt a disk cage (not shown) like a motor.

As shown in FIG. 5, the first magnetic module 22 includes two permanent magnets 221 (for example: magnets), one long bowl-shaped magnetic conductor 222 (for example: metal material, silicon steel plate, or iron block), and Both position adjustment units 223 are included. Among them, the both position adjusting units 223 are respectively installed in the two storage tanks 2121. The two magnets 221 are located in the two storage tanks 2121, respectively, and are installed on the two position adjusting units 223. The magnetic conductor 222 is embedded in the spiral blade 212, and both the magnets 221 are in contact with opposite ends of the magnetic conductor 222. Further, the opposite edges of the magnetic conductor 222 are relatively well cut off at the edges of the magnets 221 that are far away from each other, so that the magnetic force can be completely transmitted. However, the present invention is not limited to this.

It should be explained that both the magnets 221 far away from the column 211 are defined as both magnetic pole ends 2211, respectively. The first magnetic module 22 can generate different magnetic forces through the magnetic pole ends 2211 (for example: the top side of the left magnet 221 in FIG. The top side is the S pole). In addition, the magnetic force generated by one of the magnets 221 can be transmitted through the magnetic conductor 222 to the other magnet 221 therein.

Among them, in the present embodiment, all the position adjusting units 223 include one spring 2231, one fixed frame 2232, and one active frame 2233. However, it is not excluded even if it is replaced with a partial element or other member. Further, the spring 2231 may be replaced with a compression spring, an extension spring, or another recoverable member.

More specifically, when viewed from one of the magnets 221 and the corresponding position adjustment unit 223 (as shown in FIGS. 5 and 6), the fixed frame 2232 and the active frame 2233 each have one tubular portion. 2232a, 2233a and one

side wing portion

2232b, 2233b extending vertically outward from the edge of each of the

tubular portions

2232a, 2233a. The fixed frame 2232 is fixed to the top of the storage tank 2121 by its side wings 2232b (for example: Helisert coil screw), and a gap G is separated between the outer surface of the tubular part 2232a and the side wall of the storage tank 2121. Yes. The magnet 221 is attached to the inside of the tubular portion 2233a of the active framework 2233. The tubular portion 2233a of the active framework 2233 is movably installed in the tubular portion 2233a of the fixed framework 2232. The side wing 2233b of the active framework 2233 is provided adjacent to the bottom of the storage tank 2121. Thereby, through the above installation, the active framework 2233 has only one degree of freedom corresponding to the fixed framework 2232.

Further, the spring 2231 is installed in a gap G formed between the outer surface of the tubular portion 2232 a of the fixed frame 2232 and the side wall of the storage tank 2121. Further, opposite ends of the spring 2231 (for example, the top end and the bottom end of the spring 2231 in FIG. 5) are in contact with the side wing portion 2232 b of the fixed frame 2232 and the side wing portion 2233 b of the active frame 2233, respectively. Accordingly, the spring 2231 can be deformed when the magnet 221 is moved under a force (for example, a centrifugal force described below). The deformed spring 2231 tends to return the magnet 221 (or the active framework 2233) to the position before the displacement. As a result, the active frame 2233 reciprocates with respect to the fixed frame 2232 (or the magnetic conductor 222) through the centrifugal force and the force applied by the spring 2231.

The above is described for the structure of the stator module 1 and the rotor module 2 of this embodiment. The following will continue to introduce the operating principle between the stator module 1 and the rotor module 2 and the relative relationship between them.

As shown in FIG. 5, when the rotating part 21 is stationary, the magnet 221 and the active framework 2233 are all located on the groove bottom of the storage tank 2121. At this time, the rotating part 21 of the magnet 221 is positioned. The position relative to (or the storage tank 2121) is defined as the first position (as shown in FIG. 5).

When a fluid (for example, wind power) outside the power generation device 100 enters the flow passage 113 of the casing 11 and applies a driving force to the spiral blade 212 of the rotating part 21, the rotating part 21 moves along the axis L. Rotates as an axis. The two magnets 221 are moved to a second position (in FIG. 6) along the direction far from the axis L with respect to the rotating part 21 by the action of centrifugal force generated by the rotation of the rotating part 21. As shown). Then, a restoring force is stored in the springs 2231 of all the position adjustment units 223, thereby driving the tendency to restore both the magnets 221 to the first position. Among them, the second position where each of the magnets 221 is located is far from the groove bottom of the storage tank 2121 but protrudes from the edge of the rotating part 21 (that is, the inlet of the groove of the storage tank 2121). There is no position. In addition, when the magnet 221 of the present embodiment is moving, the tubular portion 2233a of the active frame 2233 is guided through the tubular portion 2232a of the fixed frame 2232, whereby the magnet 221 in the tubular portion 2233a of the active frame 2233 is guided. A linear motion can be performed with respect to the storage tank 2121.

Therefore, when the rotating part 21 is continuously rotating, the magnets 221 and the active framework 2233 are all held in the second position. That is, both the magnets 221 and the inner edge of the flow pipe 111 of the casing 11 are held at the closest distance. As a result, when the rotor module 2 has been rotated to one predetermined position, both the magnetic pole ends 2211 of the first magnetic module 22 are respectively in the radial direction and one of the first magnetic guide units 121 therein. The two core portions (as shown in FIG. 6, the center lines C of the core portions 1211 pass through the magnets 2213, respectively, when they are in a predetermined position). Further, the magnets 221 come into contact with the flexible magnetic guide brush 122 and further advance, so that the magnets 221 pass through the flexible magnetic guide brush 122 to the cores 1211. To communicate. As a result, an induced current is generated in the coil 1212 wound around the cores 1211 to generate power.

To go one step further, when the rotor module 2 has rotated to a predetermined position with the axis L as the axis, both magnetic pole ends 2211 of the first magnetic module 22 are arranged in the radial direction. Toward the two core portions 1211 of the first magnetic guide unit 121 of the first magnetic guide unit 121 and in contact with the free ends of the two flexible magnetic guide brushes 122 on the two core portions 1211 respectively. The magnetic force generated from the extreme 2211 is the first magnetic module 22 (that is, both the magnets 221 and the magnetic conductor 222), the flexible magnetic guide brush 122, and the first magnetic guide unit 121 (that is, both the core portion 1211 and the guide part 1213). ) To form one magnetic loop F. More specifically, since the first magnetic guide module 12 includes a plurality of first magnetic guide units 121, when the rotor module 2 rotates about the axis L, the first magnetic force The module 22 sequentially goes toward the first magnetic guide unit 121, and the magnetic force generated through the magnetic pole ends 2211 passes along the first magnetic module 22 and the first magnetic guide unit 121 facing the first magnetic guide unit 121. A magnetic loop F is formed.

As a result, the magnet 221 transmits the magnetic force to the core portion 1211 of the first magnetic guide unit 121 through the flexible magnetic guide brush 122, and thus between the core portion 1211 corresponding to the magnetic pole end 2211 of the magnet 221. The transmission of magnetic force becomes 0 gap, and thereby, the effect of raising the transmission of magnetic force can be achieved. In addition, the problem that the magnet 221 or the spiral blade 212 collides with the core portion 1211 due to an inappropriate design of the gap is avoided. When the rotor module 2 can rotate relative to the stator module 1, the power generation device 100 generates power with a magnetic loop F configured by the first magnetic module 22 and the first magnetic guide unit 121. Reach the effect of raising the amount. And the quantity of the 1st magnetic guide unit 121 can be increased according to a demand, and electric power generation amount can be raised further.

If the fluid (for example: wind power) outside the power generation device 100 no longer enters the flow passage 113 of the casing 11, the rotational speed of the rotating part 21 gradually decreases and rotates until the speed stops. At this time, the centrifugal force is smaller than the recovery force, and the spring 2231 gradually releases the recovery force at the same time, and thus the side wing portion 2232b of the fixed frame 2232 and the side wing portion 2233b of the active frame 2233 are pushed forward. The magnet 221 fixed to the active framework 2233 is driven to move from the second position to the first position.

Further, as shown in FIGS. 2 to 4, the stator module 1 of this embodiment can be provided with the second magnetic guide module 13 in the casing 11, and the second magnetic guide module 13 includes a plurality of second magnetic guide modules 13. Two magnetic guide units 131 may be included. In the rotor module 2 of the present embodiment, the second magnetic module 23 can be installed on the spiral blade 212 of the rotating part 21. Among them, the structure and installation principle of the second magnetic guide module 13 and the second magnetic module 23 are almost the same as those of the first magnetic guide module 12 and the first magnetic module 22 described above. The second magnetic module 23 will not be described in detail.

Furthermore, the position, quantity, and shape of the spring 2231 in the position adjustment unit 223 can also be adjusted according to the designer's demand. For example: As shown in FIGS. 7 and 8, the first magnetic module 22 includes only one positioning unit 223. The magnets 221, the magnetic conductor 222, and the position adjustment unit 223 of the first magnetic module 22 are all installed in the same storage tank 2121. Moreover, the magnets 221 are in contact with opposite ends of the magnetic conductor 222. The spring 2231 can be a substantially C-shaped or U-shaped plate (not shown), which is similar to a leaf spring. The central portion of the plate-shaped spring 2231 is fixed to the bottom of the groove of the storage tank 2121, and both ends of the plate-shaped spring 2231 are in contact with (attached to) the lower surface of the magnetic conductor 222 below the magnets 221. ), Thereby providing a corresponding restoring force between the magnet 221 and the magnetic conductor 222.

9 to 11 show a second embodiment of the present invention. The present embodiment is generally similar to the above embodiment, and the description of the same portion is omitted. The main difference between the two is the guide part 1213 of the first magnetic guide module 12.

Specifically, as shown in FIGS. 9 and 10, the first magnetic guide module 12 includes one guide part 1213. That is, one of the first magnetic guide units 121 includes the guide part 1213. The other first magnetic guide unit 121 simply includes a core portion 1211 and a coil 1212. Among them, the guide part 1213 is installed in the casing 11 and includes a circular magnetic guide ring 1213a and at least one magnetic guide connection portion 1213b for connecting the magnetic guide rings 1213a. In this embodiment, a plurality of the magnetic guide connecting portions 1213b are exemplified.

More specifically, both the cores 1211 of all the first magnetic guide units 121 are positioned inside the magnetic guide rings 1213a, respectively, and both the cores 1211 of all the first magnetic guide units 121 are respectively The magnets 221 of the first magnetic force module 22 are in phase connection with both the magnetic guide rings 1213a, and are located within the space surrounded by the magnetic guide rings 1213a. As a result, the magnetic force generated from the magnet 221 causes one core portion 1211 of all the first magnetic guide units 121, one magnetic guide ring 1213a therein, the adjacent magnetic guide connection portion 1213b, and the other one of them. One magnetic guide ring 1213a is transmitted in order to another core portion 1211 therein. That is, the magnetic force passes along the first magnetic force module 22, the core portions 1211 of all the first magnetic guide units 121, and the guide parts 1213, thereby forming one magnetic loop F.

Furthermore, the outer surface of the guide part 1213 does not protrude from the outer surface of the casing 11. That is, in this embodiment, the outer surface of the guide part 1213 is roughly cut into the outer surface of the casing 11. However, the present invention is not limited to this. For example, the guide part 1213 can be buried in the casing 11 (not shown) or can be protruded from the casing 11 (not shown). In addition, in the present embodiment, the guide part 1213 of the first magnetic guide module 12 has been described as an example. However, the guide part 1213 (not shown) of the second magnetic guide module 13 is also of the first magnetic guide module 12. A structure similar to that of the guide part 1213 can also be formed.

In addition, as shown in FIG. 11, the magnetic guide ring 1213a and the core part 1211 connected to each other are integrally molded or separated and can be joined together. And it is formed by stacking along the direction of the parallel axis L using a plurality of metal plates 1214 (for example: silicon steel plate, iron plate). That is, the circular ring-shaped portion 1214a of the metal plate 1214 is stacked on each other to form the magnetic guide ring 1213a, and the T-shaped protrusion connected to the ring-shaped portion 1214a in the metal plate 1214 is formed. The core portions 1211 are configured by stacking the portions 1214b that are present. The magnetic guide connecting portion 1213b can also be formed by stacking a plurality of metal plates (not shown), but there is no particular limitation here.

Based on this, through the design of the guide part 1213 of the present embodiment, the guide part 1213 is more easily coupled to the casing 11 when manufacturing the guide part 1213, thereby simplifying the processing difficulty and assembly complexity of the stator module 1. To further advance production and production.

As described above, when the power generation apparatus provided by the embodiment of the present invention has rotated to the position where the rotor module is located, the magnetic pole ends of the first magnetic module are each of the core portion along the radial direction. The free magnetic end of the upper flexible magnetic guide brush is substantially in contact with it, and the magnetic force generated from the magnet is transmitted to the core through the flexible magnetic guide brush. As a result, the transmission of magnetic force and the effect of raising the amount of power generation can be achieved, and the problem that the magnet or the spiral blade collides with the core due to the improper design of the gap is avoided.

What has been described above is a comparatively good embodiment of the present invention, and the present invention is not limited to the configuration and the specific usage method described in each of the above embodiments. The manner of use can be varied and should be included in the interpretation of the scope of the present invention.
