The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The structure of a wind power generator 100 according to an embodiment of the present application is described below with reference to fig. 1 to 14.

As shown in fig. 1, a wind power generator 100 according to an embodiment of the present application includes: vane means, vane stop means, truss 3 and tube assembly.

The vane device comprises inflatable vanes 11, the inflatable vanes 11 are composed of double-layer air bags, wherein when the inflatable vanes 11 are inflated with air, as shown in fig. 1 and 5, the inflatable vanes 11 can form a hemispherical shape under the action of the air, and the inflatable vanes 11 can be contracted to a very small size when not inflated with air, as shown in fig. 4, the inflatable vanes 11 naturally fall under the action of gravity when no air is inflated, and a user can contract and stack the inflatable vanes 11.

The blade limiting device comprises a reed 21 which can be elastically bent, and the bending and straightening actions can be repeated for many times without permanent deformation. The inflatable vane 11 is mounted to the spring 21 in an expandable manner. The reed 21 is made of metal sheet with good memory function, the reed 21 can be bent and deformed after being stressed and can keep a straight state when not stressed, and the inflatable vane 11 can be adhered to the edge of the reed 21.

The first end of the spring plate 21 is rotatably connected with the truss 3, the second end of the spring plate 21 is slidably mounted on the truss 3, and the wind power generator 100 is configured such that the inflatable vane 11 inflates and forms a resistance chamber after the second end of the spring plate 21 is slid to a set position toward the first end of the spring plate 21. That is, the first end of the spring 21 is mounted to the truss 3, and the spring 21 can rotate relative to the truss 3 at the first end thereof, and the second end of the spring 21 can slide relative to the truss 3 to enable the spring 21 to be deformed. Wherein the set position may be a position where the spring 21 is bent to a circular shape.

As shown in fig. 3, the first end of the spring plate 21 is rotatably connected to the end of the truss 3, and the second end of the spring plate 21 is slidably engaged with the middle position of the truss 3. As shown in fig. 3, the reed 21 is in a flat state, and at this time, the inflatable vane 11 is housed in the reed 21, and the inflatable vane 11 and the reed 21 occupy a smaller space, which is convenient for housing; as shown in fig. 4, the second end of the spring plate 21 slides along the truss 3 towards the first end thereof, so that the spring plate 21 is bent and deformed, and the inflatable vane 11 is in an expanded state, and the resistance chamber formed by the inflatable vane 11 has a large wind resistance surface.

It should be noted that the user can manually push the second end of the spring plate 21 to move relative to the first end of the spring plate 21, so as to bend the spring plate 21 as a whole. Thus, when the wind driven generator needs to be carried out, a user can directly push the second end of the reed 21 to slide, so that the reed 21 can be bent and deformed, the inflatable blades 11 can be expanded, and the power generation effect is realized. When the power generation of the gas-filled generator 100 is not needed, the gas in the gas-filled blades 11 can be discharged, and the reeds 21 are restored to the straight state under the action of the elastic restoring force, so that the gas-filled blades 11 can be folded and contracted into the reeds 21. It should be noted that, an installation cavity with one open side is arranged in the truss 3, and the inflatable vane 1 can be folded into the installation cavity after being deflated.

Truss 3 is rotatably mounted to the tube assembly, which has a first receiving slot 41 for receiving truss 3, the first receiving slot 41 being provided in the outer peripheral wall of the tube assembly. Wherein the tube assembly comprises a tube 4 and a hub 6, as shown in fig. 2, the hub 6 is rotatably mounted at the upper end of the tube 4, the truss 3 is rotatably mounted at the hub 6, the first receiving groove 41 is provided at the outer circumferential wall of the tube 4, and the first receiving groove 41 extends along the axial direction of the tube 4.

It should be noted that the generator 8 is disposed inside the tube 4 of the tube assembly, wherein the inflatable vane 11 is in power connection with the generator 8 through the reed 21, the truss 3 and the hub 6, so that the inflatable vane 11 can drive the generator 8 to generate electricity under the action of wind power.

Therefore, when the wind turbine 100 is in normal use, the truss 3 and the spring plate 21 can be opened, and the inflatable vane 11 is inflated to form a resistance chamber, so that the wind turbine 100 can perform an effective power generation function, and when the wind turbine 100 is not in use, the gas in the inflatable vane 11 can be discharged, the inflatable vane 11 is accommodated in the spring plate 21 and is vertically mounted on the truss 3, and further, the truss 3, the spring plate 21 and the inflatable vane 11 are accommodated in the first accommodating groove 41. That is to say, aerogenerator 100 in this application can be in the nimble switching under two kinds of states, both can realize wind power generation, can fold when unoperated state again and receive and put, and aerogenerator 100 of this application is small in size, the quality is light promptly, has environmental suitability, the breeze can generate electricity and conveniently carries advantages such as.

According to the wind driven generator 100 of the embodiment of the application, the two states can be flexibly switched, the wind driven generator can be used for generating power, and can be folded and stored in a non-working state, and the wind driven generator 100 is simple in structure, small in size, light in weight, strong in environmental adaptability, capable of generating power by breeze, convenient to carry and the like.

In some embodiments, as shown in fig. 1, 4-6, the spring plate 21 comprises an upper spring plate 221 and a lower spring plate 222, the upper spring plate 221 and the lower spring plate 222 are disposed opposite to each other, the shape of the upper spring plate 221 and the lower spring plate 222 during operation can be designed to be a shuttle shape, an oval shape or other shapes besides an approximately circular shape, the inflatable vane 11 is installed between the upper spring plate 221 and the lower spring plate 222, and after the upper spring plate 221 and the lower spring plate 222 are bent in a direction away from each other, the inflatable vane 11 is inflated towards the inside of the inflatable vane 11 so that the inflatable vane 11 defines a resistance chamber between the upper spring plate 221 and the lower spring plate 222.

Wherein, the user can manually push the second end of the upper spring 221 to slide relative to the first end of the upper spring 221, and the second end of the lower spring 222 slides relative to the first end of the lower spring 222, so as to facilitate the bending deformation of the upper spring 221 and the lower spring 222 in the direction away from each other, and the operation is convenient.

As shown in fig. 1, the inflatable vane 11 is located between the upper spring leaf 221 and the lower spring leaf 222, and the upper spring leaf 221 and the lower spring leaf 222 have the same length, such that the upper spring leaf 221 and the lower spring leaf 222 are respectively disposed at the upper side and the lower side of the truss 3, the first end of the upper spring leaf 221 and the first end of the lower spring leaf 222 are both rotatably connected to the free end of the truss 3, the second end of the upper spring leaf 221 and the second end of the lower spring leaf 222 are both slidably fitted to the middle of the truss 3, the upper half portion of the inflatable vane 11 is connected to the upper spring leaf 221, and the lower half portion of the inflatable vane 11 is connected to the lower spring leaf 222, wherein the installation cavity of the truss 3 is opened towards the side between the upper spring leaf 221 and the lower spring leaf 222, so that the inflatable vane 11 can be folded into the installation cavity of the truss 3 from between the upper.

Thus, when the wind turbine 100 generates electricity, the upper spring leaf 221 and the lower spring leaf 222 are bent and deformed upwards and downwards respectively, so that the inflatable blade 11 is expanded between the upper spring leaf 221 and the lower spring leaf 222, at this time, the inflatable blade 11 is inflated, and the inflatable blade 11 is expanded between the upper spring leaf 221 and the lower spring leaf 222 to form a resistance cavity for wind power generation. When the wind driven generator 100 is in a non-wind power generation state, the inflatable blade 11 can be retracted between the upper spring leaf 221 and the lower spring leaf 222, so that a user can conveniently retract the inflatable blade 11, the upper spring leaf 221 and the lower spring leaf 222 into the truss 3, and then the inflatable blade 11, the upper spring leaf 221 and the lower spring leaf 222 are collectively retracted into the first accommodating groove 41 of the pipe barrel 4.

That is to say, the upper spring leaf 221 and the lower spring leaf 222 are both rotatably mounted on the truss 3 through the tenon 23, and the sliding of the tenon 23 relative to the truss 3 can drive the upper spring leaf 221 and the lower spring leaf 222 to switch between the semicircular state and the straight state, so that the upper spring leaf 221 and the lower spring leaf 222 can smoothly slide relative to the truss 3, and the inflatable blade 11 can be smoothly opened, thereby ensuring that the wind turbine 100 can rapidly enter the power generation state.

It should be noted that one end of the spring 25 is connected to the first end of the truss 3, the other end of the spring 25 is connected to the trip 23, so that the spring 25 elastically extends and contracts between the trip 23 and the truss 3, the second ends of the upper spring leaf 221 and the lower spring leaf 222 are both connected to the trip 23, and the first ends of the upper spring leaf 221 and the lower spring leaf 222 are both rotatably connected to the second end of the truss 3. Thus, after the inflatable vane 11 is inflated, the gas pressure in the inflatable vane 11 acts on the upper spring 221 and the lower spring 222, so that the inflatable vane 11 and the upper spring 221 and the lower spring 222 are supported with each other; after the inflatable vane 11 is switched from the inflation state to the deflation state, the spring 25 elastically contracts and the upper reed 221 and the lower reed 222 deform towards the straight state, wherein the elastic force of the contraction of the spring 25 can directly act on the upper reed 221 and the lower reed 222 to ensure that the upper reed 221 and the lower reed 222 can recover to the straight state, so that the problem that the upper reed 221 and the lower reed 222 are seriously deformed to cause incapability of recovery is solved, the normal operation of the wind driven generator 100 is ensured, and the rationality of the structural design is improved. As shown in fig. 13, a truss hook 34 is provided at a position close to the end of the truss 3, and a hook is provided at the end of the spring 25, and the hook is connected to the truss hook 34 in a snap-fit manner.

In some embodiments, wind turbine 100 further comprises a stop block 24, wherein stop block 24 is rotatably mounted on tenon 23, and stop block 24 is in limit fit with truss 3.

In this way, the stopper 24 can slide together with the latch 23 relative to the truss 3, and the stopper 24 can lock the latch 23 on the truss 3, specifically, when the wind turbine 100 is generating power, the upper spring 221 and the lower spring 222 are bent and deformed, and the inflatable blade 11 is opened to the maximum state, at this time, the stopper 24 can lock the latch 23, so that the inflatable blade 11, the upper spring 221 and the lower spring 222 are all kept in the current state, that is, the inflatable blade 11 can be stably kept in the expanded state to the maximum state, thereby ensuring that the wind turbine 100 has a stable power generation state.

In some embodiments, the truss 3 has a sliding cavity, the tenon 23 is slidably installed in the sliding cavity, the side wall of the sliding cavity is provided with a limiting groove 35, and the stop block 24 is in limiting fit with the limiting groove 35.

As shown in fig. 14, the sliding cavity is a hollow cavity of the truss 3, and the sliding cavity can extend along the length direction of the truss 3, so that the tenon 23 can slide along the length direction of the truss 3 in the sliding cavity, and further drives the upper spring 221 and the lower spring 222 to slide and bend and deform in the sliding process.

As shown in fig. 14, the limiting groove 35 is disposed on and penetrates through the side wall of the sliding cavity, wherein the limiting groove 35 extends along the length direction of the truss 3, wherein the stopper 24 slides in the limiting groove 35 when the tenon 23 slides relative to the truss 3, and can be locked in the limiting groove 35 by the stopper 24 so that the upper spring piece 221, the lower spring piece 222 and the inflatable blade 11 are all kept in the current state, so that the inflatable blade 11 is in a stable state, and the power generation state of the wind turbine 100 is kept stable.

It should be noted that a stop surface is formed in the stop groove, that is, when the wind turbine 100 generates electricity, the stop boss enters the stop groove and abuts against the stop surface in the stop groove, so as to keep the state of the inflatable vane 11 stable. When power generation is not needed, the stop boss can be disengaged from the stop groove and slides along the movable groove, so that the inflatable blade 11 can be conveniently contracted and expanded, and the upper reed 221 and the lower reed 222 can be conveniently switched between a straight state and a bent state.

In some embodiments, the stop block 24 is circular, the stop block 24 is rotatably mounted on the side surface of the tenon 23, the stop boss is configured to be long-strip-shaped, the movable groove is a strip-shaped groove, the stop groove is configured to be semi-circular, a flat part of the inner wall surface of the stop groove is connected with the movable groove, a curved part of the inner wall surface of the stop groove is opposite to the movable groove, and the stop boss is adapted to rotate in the stop groove to abut against the flat part of the inner wall surface of the stop groove, that is, the flat part of the stop groove is formed as a stop surface, so that the stop boss can be locked in the stop groove.

As shown in fig. 13, the stopping groove is connected to the end of the movable groove, the stopping boss extends into the movable groove and is adapted to slide in the movable groove, and when the inflatable vane 11 is spread to the maximum extent, the tenon 23 drives the stopping block 24 to move so that the stopping boss moves from the movable groove to the stopping groove. It should be noted that the width of the movable groove is greater than the width of the stop boss and less than the length of the stop boss, so that the stop boss can slide smoothly along the movable groove, and the radius of the semicircle of the stop groove is greater than the length of the stop boss, so that after the stop boss enters the stop groove along the sliding groove, the stop boss rotates 90 degrees under the action of the curved surface of the stop groove and gradually abuts against the plane part of the stop groove, and the locking of the latch 23 is realized. It can be understood that the latch 23 is connected to the spring 25, and at this time, the upper spring 221 and the lower spring 222 are in a semicircular state, so that the stop boss is constantly and stably contacted with the stop surface under the tension state of the spring 25, thereby stably limiting the stop block at the current position.

In some embodiments, the tenon 23 is provided with an upper tenon tab 231, a lower tenon tab 232 and a tenon hook 233 which are arranged at intervals, the upper tenon tab 231 and the lower tenon tab 232 are respectively positioned at the upper side and the lower side of the tenon hook 233, the upper tenon tab 231 and the lower tenon tab 232 are respectively used for connecting with the upper spring leaf 221 and the lower spring leaf 222, and the tenon hook 233 is used for connecting with the spring 25.
