Description

Technical Field

[0001] The invention relates to the field of wind power generation, and in particular to a wind-driven generator set. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Conventional wind turbines include wind rotors and generators. The wind rotors contain blades, hubs, reinforcements, etc. The wind rotors are supported by a tower, and the wind source drives the wind rotors to rotate. The rotation of the wind rotors drives the generators to rotate through the transmission shaft, thereby generating electricity. Conventional wind turbines have large wind rotors, low wind flow utilization, and low conversion rates. They are also troublesome to transport and assemble.

[0003] Furthermore, conventional wind turbines are generally installed in relatively flat areas, such as plains with abundant wind sources. In some steeper canyons or mountain walls, where the wind sources are abundant and the wind direction is fixed, the installation is difficult if the conventional wind turbine structure is used. The wind rotor needs to be extended a certain distance, and the tower and wind rotor structure are easily damaged, resulting in a short maintenance cycle, which increases the difficulty and cost of maintenance.

Figure 7 and Fig.10 A similar schematic diagram is shown here.

[0072] Embodiment 2

The above-mentioned one air inlet channel, one nozzle, a corresponding number of driving recesses and corresponding secondary flow channels, exhaust ports and one exhaust channel form an independent work unit.

[0074] The gas power device also includes a shaft 2, on which the outer ring 1 and the core 3 are coaxially arranged. The shaft 2 is provided with air inlet channels 21, 22 and air outlet channels 210, 220 which are respectively connected to the air inlet channels 31, 32 and the air outlet channels 310, 320 of the core.

[0075] Furthermore, in order to further increase the intake volume, in this embodiment, a wind boosting device is also included, specifically a conventional turbocharger, the compressor air outlet of the turbocharger is connected to the intake channels 31, 32 of the gas power device, the turbine inlet of the turbocharger is connected to the exhaust channels 310, 320 of the gas power device, and the exhaust gas flowing out of the exhaust channels 310, 320 of the gas power device drives the compressor impeller of the turbocharger to rotate, thereby supercharging the wind flow input into the intake channels 31, 32 of the gas power device. No power source is required, it is directly driven by the input airflow, and no other energy is consumed. Of course, in other embodiments, the wind boosting device can also use a mechanical supercharger device driven by electricity with lower energy consumption.

[0076] Embodiment 3

[0077] The present embodiment provides a wind-driven generator set, the structure of which is substantially the same as that of the embodiment 1 or the embodiment 2, except that: Fig.11 As shown, in this embodiment, it also includes a wind source collection component, which includes a collection port 71 and a wind-guiding and pressurizing flow channel 72. One end of the wind-guiding and pressurizing flow channel 72 is connected to the collection port 71, and the other end is connected to the air intake channel of the gas power device. The collection port 71 corresponds to the wind flow direction and collects the wind flow. The collected wind flow is guided by the wind-guiding and pressurizing flow channel 72 to the air intake channel of the gas power device.

[0078] Furthermore, the collecting port 71 is a bell-shaped structure, wherein the large bell-shaped portion of the collecting port 71 corresponds to the wind flow direction, and the small bell-shaped portion is connected to the wind guiding and pressurizing flow channel 72 .

[0079] The wind source collection component is added, and its collection port 71 can be set at a location where the wind flow is more concentrated, so as to better collect the wind flow and conduct it to the air intake channel of the gas power device through the wind guide and boost flow channel 72, so that the gas power device and the power generation component can be placed in a safer and more convenient location for easy operation and maintenance. For example, when it is set on a steeper mountain wall, the collection port 71 can be set at a higher position on the mountain wall to collect more wind flow, and the wind guide and boost flow channel 72 can be set along the mountain wall to extend to the foot of the mountain, and the gas power device and the power generation component can be set at the foot of the mountain.

[0080] Embodiment 4

[0081] The wind-driven generator set provided in this embodiment has the same structure as that of the first embodiment, except that, in this embodiment, the outer ring of the gas power device replaces the rotor shaft of the power generation component and is directly connected to the coil of the power generation component, and the rotation of the outer ring drives the coil to rotate to achieve power generation.

[0082] In this way, the gas power device can be directly installed on the power generation component without the need for an additional transmission device for power transmission. It is simpler in structure and smaller in size.

[0083] Through the wind-driven generator set provided above, the structure of the conventional wind wheel is replaced by the gas power device of this case. The core of the gas power device is provided with multiple-stage flow channels, that is, the air inlet channel serves as the first-stage flow channel, and each secondary flow channel serves as the second-, third-, fourth-...,..., flow channels. The air flow acts on the driving recess of the outer ring from the first-stage flow channel, and the driving recess is connected to the second-stage flow channel. Then, it returns to the second-stage flow channel and acts on another driving recess of the outer ring, and so on, until the air flow is discharged from the exhaust channel. The whole process is carried out in the forward direction of the rotation direction of the outer ring, with large torque, high transmission efficiency, high air flow utilization rate, and the output torque further increases with the increase of the rotation speed.

[0084] At the same time, the flow channels arranged around the core effectively reduce the volume of the entire device. The more inlet flow channels are set on the core, the lower the overall weight is, which further improves the output speed and efficiency of the device. On the basis of the same wind flow rate, the wind flow utilization rate is high, the torque is large, the speed is high, and the transmission efficiency is high. The whole machine has a simple structure and a small volume, which makes transportation and assembly simple; at the same time, the significant reduction in volume allows it to be well used in special terrains, such as steep canyons or mountain walls.

[0085] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
