Detailed Description

Referring to fig. 1 and 2, an embodiment of the wind power generation method with air compression assistance according to the present invention is suitable for being performed by matching at least one main wind power generator 1 and one auxiliary wind power generator 2. The main wind power generator 1 includes a first shaft 11, a first blade module 12 connected to the first shaft 11, and a main power generation module 13 connected to the first shaft 11. The first blade module 12 is driven by wind to rotate, so that the first rotating shaft 11 also rotates, and the rotational kinetic energy of the first rotating shaft 11 is transmitted to the main power generation module 13 to be converted into electric energy for output. The main power generation module 13 includes a coil, a magnetic element, and the like, and since the structure thereof is not the point of improvement of the present invention, it will not be described. The electric energy output by the main power generation module 13 can be stored or output to a power utilization end.

The auxiliary wind power generator 2 includes a second shaft 21, a second blade module 22 connected to the second shaft 21, an auxiliary power generation module 23 detachably connected to the second shaft 21, a first clutch 24 for detachably connecting the second shaft 21 and the auxiliary power generation module 23, and an air compression module 25.

When the first clutch 24 is connected, the power generation operation principle among the second shaft 21, the second blade module 22 and the auxiliary power generation module 23 is the same as the power generation operation principle of the main wind turbine 1, and thus the description thereof is omitted. When the first clutch 24 is disengaged, the second shaft 21 is not connected to the auxiliary power generation module 23, and even if the second shaft 21 rotates, the power is not transmitted to the auxiliary power generation module 23.

The air pressure module 25 includes a detection control unit 251 signal-connected to the auxiliary power generation module 23, an air compressor 252 signal-connected to the detection control unit 251 and detachably connected to the second shaft 21, a second clutch 253 signal-connected to the space between the second shaft 21 and the air compressor 252 and connected to the detection control unit 251, an air storage container 254 connected to the air compressor 252 and used for storing high pressure air, and an air pressure motor 255 connected to the air storage container 254 and the first shaft 11 of the main wind turbine 1. The detection control unit 251 can detect the gas storage amount of the gas storage container 254 and the power storage amount of the auxiliary power generation module 23, and control the clutch state of the first clutch 24 and the second clutch 253. The operation of the air compression module 25 will be described later.

Referring to fig. 1 to 3, the wind power generation method of the present embodiment includes:

step 31: a wind-receiving operation step is performed. When the wind power is enough, the main wind power generator 1 is continuously driven by the wind power to operate, and the rotating energy is converted to generate electric energy, and the electric energy can be stored or output to a power utilization end. The auxiliary wind power generator 2 operates and converts wind power into high pressure air to be stored, and further, when the high pressure air is full, the auxiliary wind power generator 2 is driven by wind power to operate continuously, thereby converting kinetic energy to generate electric energy.

Specifically, in the wind operation step, the second blade module 22 of the auxiliary wind power generator 2 and the second shaft 21 are driven by wind to start operation, and at this time, the first clutch 24 is disconnected, and the second clutch 253 is connected, so that the rotation power of the second shaft 21 drives the air compressor 252 to operate, and the air compressor 252 generates high-pressure air and transmits the high-pressure air to the air storage container 254 for storage. When the air container 254 is full of high pressure air, the detecting and controlling unit 251 detects the full state of high pressure air, and the detecting and controlling unit 251 further controls the second clutch 253 to be disconnected and controls the first clutch 24 to be connected, so that the subsequent rotation power of the second blade module 22 and the second shaft 21 is transmitted to the auxiliary power generating module 23 to generate electric energy. The electric energy generated by the auxiliary wind power generator 2 can be stored first, and when the electric power output to the power utilization end by the main power generation module 13 is insufficient, the electric energy generated by the auxiliary power generation module 23 is used in cooperation.

Step 32: an air compression assisting step is performed. When the wind is insufficient to drive the main wind power generator 1 to operate, the auxiliary wind power generator 2 releases the stored high-pressure air, thereby driving the main wind power generator 1 to operate to generate electric power.

Specifically, the detection control unit 251 continuously detects the air storage amount of the air storage container 254 and the electric storage amount of the auxiliary power generation module 23, and if the air storage amount of the air storage container 254 is full and the electric storage amount of the auxiliary power generation module 23 continuously increases, indicating that the external wind power continuously acts, the main wind power generator 1 and the auxiliary wind power generator 2 can both continuously operate in the wind receiving operation step. If the power storage capacity of the auxiliary power generation module 23 is not increased any more, which means that the second blade module 22 is not rotated by the wind force any more, which means that the wind force is insufficient, the air pressure assisting step is performed, the detecting and controlling unit 251 controls the air container 254 to release the high pressure air to the air pressure motor 255, and the air pressure motor 255 is driven by the high pressure air to operate, which is equivalent to converting the energy of the high pressure air into kinetic energy. Then, the pneumatic motor 255 drives the first shaft 11 of the main wind power generator 1 to rotate, the first blade module 12 further rotates, and the main power generation module 13 converts the kinetic energy of the first shaft 11 into electric energy. That is, when the wind is insufficient, the main wind power generator 1 cannot be operated originally, but the air compression assisting step is performed, so that the main wind power generator 1 can be driven to operate by the high-pressure air stored in the air compression module 25, and the main wind power generator 1 can continuously generate electric energy.

Further, when the wind force is sufficient again to drive the main wind power generator 1 to operate during the air pressure assisting step, the auxiliary wind power generator 2 stops releasing the high pressure air, and then the wind receiving operation step is performed. That is, the main wind power generator 1 can be driven by wind power again to operate, and the auxiliary wind power generator 2 is driven by wind power to store high-pressure air again until the high-pressure air is full, and then the high-pressure air is converted to drive the auxiliary power generation module 23 to generate electric energy. Thus, the wind receiving operation step and the air compression assisting step are continuously and circularly performed, so that the electric energy of the main wind driven generator 1 can be ensured to be stably and continuously output.

It should be noted that the structure and connection relationship of the elements of the main wind turbine 1 and the auxiliary wind turbine 2 shown in the drawings of the present invention are merely exemplary, and the connection and transmission structure between the mechanical elements can have many designs, so the drawings and the foregoing description are not necessarily limited. For example, the relative relationship between the first rotating shaft 11 and the main power generation module 13 is not limited to that shown in the drawings, as the arrangement relationship between the two is only required to enable the main power generation module 13 to generate electric energy after the first rotating shaft 11 rotates. In the above description, the auxiliary wind power generator 2 and the main wind power generator 1 are in a one-to-one relationship, but the present invention is not limited to this, and referring to fig. 4, a one-to-many relationship may be adopted, and parameters such as blade size, related element size, power, and the like of each generator are appropriately designed, so that the high-pressure air stored in the auxiliary wind power generator 2 can drive a plurality of main wind power generators 1, so that a plurality of main wind power generators 1 can continuously and stably generate electric energy.

In summary, the wind power generation method of the present invention matches the wind-receiving operation step with the air compression auxiliary step, so that the main wind power generator 1 can still be driven by the high-pressure air stored in the auxiliary wind power generator 2 to operate when the wind power is insufficient, and further can continuously generate electric energy, therefore, the electric energy can be stably output to be stored or transmitted to the electricity-consuming end for use no matter there is wind or no wind.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
