[0002] The existing new energy technologies in China are generally scaled and commercialized, and all of them are single wind power generation or photovoltaic power generation, which cannot effectively utilize wind and light to generate power. For example, wind power generation can only generate power in windy conditions, and cannot generate power when there is no wind. Photovoltaic power generation can only generate power in sunny days and during the day, which forms intermittent power supply and unstable power supply. Even though some street lamps or some lighting devices use small wind and light power generation devices, the devices cannot be scaled and commercialized, or the wind power generation and photovoltaic power generation are simply combined, such as being fixed together, which has poor correlation and low integration. SUMMARY

[0005] A impeller shaft 1 is arranged in the wind channel, and the impeller shaft 1 is connected to a generator 8, so that the generator 8 is driven to generate power through the rotation of the impeller shaft 1.

[0006] As a kind of scheme, the impeller shaft 1 is arranged at the rear end of the wind channel.

[0007] As a kind of scheme, the impeller shaft 1 is arranged at the front end of the wind channel.

[0008] Further, the impeller shaft 1 comprises a rotating shaft 4, a blade 102 is fixedly connected to the outer periphery of the rotating shaft 4, one end plate 101 is fixedly connected to the two ends of the blade 102 respectively, at least one intermediate partition plate 103 is fixedly connected to the middle of the blade 102, a first bearing seat 401 is rotatably connected to the two ends of the rotating shaft 4 respectively, the first bearing seat 401 is fixedly connected to the rack 7, and the rotating shaft 4 extends from the first bearing seat 401 at one end and is fixedly connected to a driving bevel gear 402.

[0009] Furthermore, at least one second bearing seat 501 is fixedly connected to the side of the frame 7, and a transmission shaft 5 is rotatably connected inside the second bearing seat 501.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] As attached Figures 1-7 As shown, a wind-solar combined power generation device includes a frame 7, on which at least one photovoltaic panel 201 is fixedly connected, and on which at least one guide plate 202 corresponding to the photovoltaic panel 201 is fixedly connected, and a wind duct is formed between the guide plate 202 and the photovoltaic panel 201, the cross-sectional area of ​​the wind duct decreasing from the rear end of the guide plate 202 to the front end of the guide plate 202.

[0025] An impeller shaft 1 is installed inside the air duct, and the impeller shaft 1 is connected to a generator 8, so that the rotation of the impeller shaft 1 drives the generator 8 to generate electricity.

[0026] Preferably, baffles are provided on both sides of the air duct and fixed to the guide plate 202 and the photovoltaic panel 201 respectively, so as to form a variable diameter (closed flow tube) structure and reduce lateral air leakage.

[0027] Preferably, the photovoltaic panels 201 are arranged in a stepped manner as shown in the figure, and the front end of the guide plate 202 that forms an air duct with the photovoltaic panels 201 abuts against the rear end of another photovoltaic panel 201 below.

[0028] In existing photovoltaic power generation structures, there is an integrated photovoltaic panel structure. The photovoltaic panel has a large volume, and when subjected to wind pressure, stress concentration is easily formed in the middle and near the photovoltaic panel. Excessive wind pressure can lead to damage. Therefore, this utility model preferably arranges the photovoltaic panels 201 in a dispersed or even stepped manner, and forms a corresponding dispersed wind duct structure to reduce the damage caused by stress concentration.

[0029] Preferably, the width of the impeller shaft 1 matches the width of the duct where it is located, and the working clearance is less than 10mm.

[0030] The following solutions are proposed for different usage scenarios: For operating conditions with large air volumes, as shown in the attached... Figure 1 As shown, the impeller shaft 1 is located at the rear end of the air duct, that is, between the rear end of the guide plate 202 and the photovoltaic panel 201. Natural wind energy first enters from the large air inlet at the rear end of the air duct to drive the impeller shaft 1 to rotate and work. Then, the airflow after the impeller shaft 1 has worked enters the air outlet and overflows, cooling the photovoltaic panel 201. Under the condition of large air volume, the air volume loss can be ignored (at the same time, the airflow flowing out from the air outlet diagonally downwards can also serve as a cleaning function for the photovoltaic panel 201). The transmission mechanism drives the photovoltaic generator to generate electricity, and then connects to the photovoltaic inverter through wires and is connected to the grid or energy storage device. Part of the airflow rushes out of the air outlet, and the other part of the airflow that does not have time to overflow will turn back and impact the fan blades in the opposite direction to continue driving the fan to rotate clockwise, realizing the effect of reciprocating airflow. The inclined stepped photovoltaic panel 201 is divided into several parallel blocks, each preferably inclined at 30-35 degrees and staggered at the top and bottom, and then connected end to end. The inclined arrangement of the photovoltaic panel can increase the light-receiving area of ​​the photovoltaic panel and increase the power generation, thereby increasing the power generation. Then, it is connected to the photovoltaic inverter and connected to the grid or energy storage device through wires. Preferably, the bottom of the frame 7 can be equipped with a height-adjustable vertical telescopic support leg, which can be a structure with cylinder as the main body. The output end of the support leg is connected to the frame 7 through a ball shaft. The height of the device can be adjusted according to the airflow intensity of the terrain.

[0031] Another solution: For operating conditions with low airflow (light breeze), as shown in the attached... Figure 2 As shown, the impeller shaft 1 is located at the front end of the air duct. Through the narrow tube effect, the wind speed and wind pressure are increased, ensuring the cooling effect on the photovoltaic panel 201, and driving the smaller impeller shaft 1 to generate electricity and ensure rotation.

[0032] Further details are attached. Figure 4As shown, the impeller shaft 1 includes a rotating shaft 4, with blades 102 fixedly connected to the outer periphery of the rotating shaft 4. An end sealing plate 101 is fixedly connected to each end of the blades 102 to reduce side flow (forming a closed guide tube). At least one intermediate partition plate 103 is fixedly connected to the middle of the blades 102. A first bearing seat 401 is rotatably connected to each end of the rotating shaft 4. The first bearing seat 401 is fixedly connected to the frame 7. One end of the rotating shaft 4 extends out from the first bearing seat 401 and is fixedly connected to the drive bevel gear 402.

[0033] Further details are attached. Figure 5 As shown, at least one second bearing seat 501 is fixedly connected to the side of the frame 7. A drive shaft 5 is rotatably connected inside the second bearing seat 501. A driven bevel gear 502 is fixedly connected to the drive shaft 5. A drive gear 503 is fixedly connected to the end of the drive shaft 5. A driven gear 81 that meshes with the drive gear 503 is fixedly connected to the input end of the generator 8. This allows multiple impeller shafts 1 to drive the same drive shaft 5 to rotate and generate electricity.

[0034] Furthermore, a set of impeller shafts 1 are respectively installed at the front and rear ends of the air duct. Two solutions are proposed for this situation:

[0035] 1. As attached Figure 6 As shown, a set of impeller shafts 1 at the front end of the duct is driven by a drive shaft 5, and another set of impeller shafts 1 at the rear end of the duct is driven by another drive shaft 5. The driving gears 503 of the two drive shafts 5 mesh with the driven gears 81 of the same generator 8. The advantage of this scheme is that it uses the same generator 8, which saves costs. However, the disadvantage is that due to the meshing relationship of the gears, the two sets of impeller shafts 1 at the front and rear ends of the duct must maintain a certain proportional relationship for rotation. If the gear transmission ratio is not designed properly, it will cause the machine to jam.

[0036] 2. As attached Figure 7 As shown, a set of impeller shafts 1 are respectively installed at the front and rear ends of the air duct. The set of impeller shafts 1 at the front end of the air duct is driven by a transmission shaft 5. The driving gear 503 of the transmission shaft 5 meshes with the driven gear 81 of a generator 8.

[0037] Another set of impeller shafts 1 at the rear end of the air duct is driven by another drive shaft 5. The drive gear 503 of the drive shaft 5 meshes with the driven gear 81 of another generator 8. This design is more reasonable, but it also means that an additional generator 8 needs to be provided.

[0038] The generator 8 is preferably fixed on the frame 7, and its output is connected to the inverter and then connected to the power grid or energy storage device via a wire.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
