Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a small wind power generation energy storage device. Background Art

[0002] A wind turbine is a device that uses wind power to rotate the blades on the machine, thereby driving the internal generator rotor to rotate. The essence of the generator is to rotate the rotor, driving the internal metal coil to cut the magnetic lines of force in the magnetic field, thereby generating electric current. Therefore, whether it is a wind turbine or a steam turbine, you only need to make the rotor rotate in the correct direction.

[0003] Common large wind turbines are usually installed in open mountainous areas, grasslands and other places. This type of power generation equipment is not convenient to be arranged in urban areas and densely populated areas. Therefore, in some densely populated areas, if wind power generation is to be adopted, a smaller power generation device is required. However, in densely populated areas, the wind direction is also prone to change. Changing the wind box will make the fan blades of the power generation device unable to rotate, and thus unable to generate electricity. Therefore, a new type of power generation device is needed to solve this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a small wind power generation energy storage device, which can be installed in densely populated areas and can avoid the device from being unable to generate electricity due to changes in wind direction.

[0005] The technical solution for achieving the purpose of the utility model is: a small wind power generation and energy storage device, including a shell, the shell is provided with ventilation holes, a pneumatic component and a power generation component are arranged inside the shell, the pneumatic component includes a rotating sleeve, a rotating plate and a rotating shaft, the rotating sleeve is rotatably connected to the inner wall of the shell, a plurality of rotating plates are fixedly connected to the rotating sleeve, the rotating shaft is fixedly connected to the inside of the rotating sleeve, the power generation component includes a generator and a rotating rod, the generator is fixedly connected to the bottom inner wall of the shell, and the rotating rod is fixedly connected to the rotor of the generator.

[0006] Preferably, the pneumatic component further includes a ventilation net, and the ventilation net is arranged at the bottom of the shell.

[0007] Preferably, the power generation assembly further includes a fixed plate, a rotating drum and a first gear, the two fixed plates are fixedly connected to the inner wall of the outer shell, the two rotating drums are rotatably connected to the two fixed plates respectively, and the two first gears are fixedly connected to the two rotating drums respectively.

[0008] Preferably, the power generation assembly further includes a second gear, the second gear is fixedly connected to the rotating rod, and the two first gears are meshed with the second gear.

[0009] Preferably, the power generation assembly further includes a ratchet and a pawl, the two ratchets are fixedly connected to the rotating shaft, the two pawls are respectively fixedly connected to the inside of the two rotating drums, and the two pawls are respectively engaged with the two ratchet wheels.

[0010] Preferably, the two ratchet wheels and the two pawls are arranged in opposite directions, and the rotating shaft passes through the two first gears but does not contact the two first gears.

[0011] Compared with the prior art, the utility model has the following significant advantages:

[0012] In the utility model, when the rotating shaft rotates clockwise, it will drive one of the ratchet wheels to rotate, and the ratchet wheel will drive the pawl in contact with it to rotate, thereby causing the rotating drum to rotate, and the rotating drum will drive the first gear thereon to rotate, and then drive the second gear to rotate. When the second gear rotates, it will drive the rotating rod to rotate, thereby causing the rotor inside the generator to rotate, thereby generating electricity and storing energy. When the rotating shaft rotates counterclockwise, although the above-mentioned ratchet wheel rotates, because the direction of rotation changes, the pawl connected thereto no longer rotates, and the above-mentioned rotating drum will not rotate either, and the other ratchet wheel will rotate counterclockwise with the rotating shaft at this time, thereby driving the other ratchet wheel through the other pawl, The cylinder rotates counterclockwise, and at this time the other first gear rotates counterclockwise, thereby driving the second gear to rotate. Therefore, when the rotating shaft rotates clockwise or counterclockwise, it can drive the two first gears to rotate clockwise or counterclockwise respectively, but the meshing position of the two first gears and the second gear is such that when the two first gears rotate in clockwise and counterclockwise directions respectively, the second gear can rotate in the same direction. Therefore, the problem of being unable to generate electricity when the rotor rotates in different directions due to changes in wind direction is avoided, that is, when the wind direction is reversed, the rotating rod can still drive the rotor of the generator to rotate in the same direction, thereby continuing to generate electricity.

[0020] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a small wind power generation energy storage device through improvement. The technical solution of the utility model is:

[0022] like Figure 1-Figure 4 As shown, a small wind power generation and energy storage device includes a shell 1, a ventilation hole 2 is opened on the shell 1, a pneumatic component 3 and a power generation component 4 are arranged inside the shell 1, the pneumatic component 3 includes a rotating sleeve 31, a rotating plate 32 and a rotating shaft 33, the rotating sleeve 31 is rotatably connected to the inner wall of the shell 1, a plurality of rotating plates 32 are fixedly connected to the rotating sleeve 31, the rotating shaft 33 is fixedly connected to the inside of the rotating sleeve 31, and the power generation component 4 includes a generator 41 and a rotating rod 42, the generator 41 is fixedly connected to the bottom inner wall of the shell 1, and the rotating rod 42 is fixedly connected to the rotor of the generator 41.

[0023] The generator 41 is provided with a rotor inside. The generator 41 can generate electricity and store electricity only if the rotor rotates. The rotor is connected to the rotating rod 42. The generator 41 can generate electricity only if the rotating rod 42 rotates. However, according to the power generation principle of the generator 41, the rotating rod 42 can only generate electricity when it rotates in one direction. If the rotating rod 42 rotates in the opposite direction, it cannot generate electricity. Therefore, the rotating rod 42 needs to always rotate in the same direction.

[0024] Furthermore, the pneumatic assembly 3 also includes a ventilation net 34, which is arranged at the bottom of the housing 1. The ventilation net 34 is used to allow air to circulate so that the rotating plate 32 can rotate without being unable to rotate due to airflow obstruction.

[0025] Furthermore, the power generation component 4 also includes a fixed plate 43, a rotating drum 44 and a first gear 47. The two fixed plates 43 are fixedly connected to the inner wall of the outer shell 1, the two rotating drums 44 are respectively rotatably connected to the two fixed plates 43, and the two first gears 47 are respectively fixedly connected to the two rotating drums 44. The two first gears 47 are symmetrically arranged.

[0026] Furthermore, the power generation component 4 also includes a second gear 48, which is fixedly connected to the rotating rod 42. The two first gears 47 are both meshed with the second gear 48. The first gear 47 and the second gear 48 are both bevel gears. Since the two first gears 47 are symmetrically arranged and both mesh with the second gear 48, when the second gear 48 rotates, the directions of the two first gears 47 will be opposite, that is, when the second gear 48 rotates, one of the two first gears 47 will rotate counterclockwise and the other will rotate clockwise. Conversely, when the two first gears 47 rotate in different directions, the second gear 48 can be rotated in the same direction, so that the rotating rod 42 and the rotor in the generator 41 can always rotate in one direction.

[0027] Furthermore, the power generation assembly 4 also includes a ratchet 45 and a pawl 46 . The two ratchet wheels 45 are fixedly connected to the rotating shaft 33 . The two pawls 46 are respectively fixedly connected to the inside of the two rotating cylinders 44 . The two pawls 46 are respectively engaged with the two ratchet wheels 45 .

[0028] Furthermore, the two ratchet wheels 45 and the two pawls 46 are arranged in opposite directions, the rotating shaft 33 passes through the two first gears 47 but does not contact the two first gears 47, and the two ratchet wheels 45 are arranged in different directions, so that the two pawls 46 can be rotated respectively when the rotating shaft 33 rotates in different directions, that is, when the rotating shaft 33 rotates in a certain direction, one of the pawls 46 moves while the other remains stationary, and when the rotating shaft 33 rotates in another direction, the situation is opposite. Therefore, when the rotating shaft 33 rotates clockwise, one of the first gears 47 will eventually rotate with it, and when the rotating shaft 33 rotates counterclockwise, the other first gear 47 will rotate counterclockwise together with it.

[0029] The specific working method is: firstly, the device is arranged at a suitable position, and the two ends of the vent 2 are moved to a suitable direction according to the local wind direction law. When wind blows, airflow is formed in the vent 2, and the airflow causes the rotating plate 32 inside the housing 1 to rotate. However, since the device is suitable for densely populated areas, and densely populated areas are often close to inland and urban areas, the wind direction is easy to change, and the wind direction may be reversed at any time, so the direction of the rotating plate 32 may change at any time, and the direction of the rotating shaft 33 may also change, but two ratchets 45 with different directions are fixed on the rotating shaft 33, so:

[0030] When the rotating shaft 33 rotates clockwise, it will drive one of the ratchet wheels 45 to rotate, and the ratchet wheel 45 will drive the pawl 46 in contact with it to rotate, thereby causing the rotating drum 44 to rotate, and the rotating drum 44 will drive the first gear 47 thereon to rotate, and then drive the second gear 48 to rotate. When the second gear 48 rotates, it will drive the rotating rod 42 to rotate, thereby causing the rotor inside the generator 41 to rotate, thereby generating electricity and storing energy.

[0031] When the rotating shaft 33 rotates counterclockwise, although the above-mentioned ratchet 45 rotates, the pawl 46 connected thereto no longer rotates due to the change in direction, and the above-mentioned rotating drum 44 also does not rotate. At this time, the other ratchet 45 will rotate counterclockwise with the rotating shaft 33, and then drive the other rotating drum 44 to rotate counterclockwise through the other pawl 46. At this time, the other first gear 47 rotates counterclockwise, thereby driving the second gear 48 to rotate. Therefore, when the rotating shaft 33 rotates clockwise or counterclockwise, it can drive the two first gears 47 to rotate clockwise or counterclockwise respectively, but the meshing position of the two first gears 47 and the second gear 48 makes it possible for the second gear 48 to rotate in the same direction when the two first gears 47 rotate in the clockwise and counterclockwise directions respectively. Therefore, the problem of being unable to generate electricity when the rotor rotates in different directions due to wind direction changes is avoided, that is, when the wind direction is reversed, the rotating rod 42 can still drive the rotor of the generator 41 to rotate in the same direction, thereby continuously generating electricity.

[0032] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
