[0002] In recent years, wind power generation technology has developed rapidly, and wind power generation can be achieved normally in areas where wind resources are not very abundant. However, traditional wind power generation devices have low efficiency and a single power generation method, and cannot truly be started by a breeze.

[0003] The Chinese invention with the announcement number CN217462415U discloses a breeze generator, including a street light pole and a power generation unit; the street light pole: the upper end of the outer arc surface thereof is provided with a mounting rod, the front end of the mounting rod is provided with an LED lamp, the upper end of the outer arc surface of the street light pole is provided with a uniformly distributed mounting plate, the left side of the upper end of the inner cavity of the street light pole is provided with a rectifier, the bottom wall of the inner cavity of the street light pole is provided with a battery, and the front side of the upper end of the inner cavity of the street light pole is provided with an inverter; the power generation unit is arranged on the upper surface of the mounting plate; wherein: it also includes a timer switch, the timer switch is arranged on the rear side of the upper end of the inner cavity of the street light pole, and the input end of the timer switch is electrically connected to the output end of the inverter. The breeze generator can be used for street lights in tourist attractions, outdoor highway street lights, township streets, outdoor communication base stations and other areas. For places where cables are pulled over long distances, the electricity cost is greatly reduced, sustainable power generation and sustainable development can be formed, energy is greatly saved, and investment costs are reduced. The device adopts a vertical axis breeze generator, which has a simple structure and is easy to start, but has low power and low power generation efficiency.

[0004] The Chinese invention with the publication number CN106194586A discloses a wind power generation device, including a support frame, a wind power generation system arranged in the support frame, a battery structure connected to the wind power generation system, and a wind volume guide system arranged in the support frame, wherein: the support frame includes an upper clamping plate, a lower clamping plate and a plurality of support columns supporting and connecting the upper and lower clamping plates; the wind power generation system includes a wind receiving drum located between the upper and lower clamping plates and a generator connected to the wind receiving drum shaft; the wind volume guide system includes a plurality of wind guide swing blades evenly spaced and arranged around the outer periphery of the wind receiving drum and a swing blade regulating component for regulating the size of the gap between adjacent wind guide swing blades. The present invention combines wind power generation and photovoltaic power generation in one, and greatly improves the wind collection area of ​​wind power generation, greatly improves the efficiency of wind power generation, and reduces the waste of wind energy. As long as there is air flow or breeze, the present invention can be driven to work and generate electricity, providing 50 to 300 watts of electricity to users. Although the device uses solar energy and wind energy to generate electricity, which improves the energy utilization efficiency to a certain extent, the wind-guiding blades used for wind power generation are set perpendicular to the wind-receiving rotor, and the efficiency of wind power generation is still relatively low.

[0005] Therefore, it is necessary to design a wind power generation device that can generate electricity under light wind conditions and has high power generation efficiency. Summary of the invention

[0006] Therefore, in view of the low power generation efficiency of wind power generation devices in the prior art and the inability to truly achieve breeze start-up, the purpose of the present invention is to provide a wind power generation device and an array-compensated solar-wind power generation equipment to solve the problem that traditional wind power generation devices have low power generation efficiency and cannot achieve breeze start-up.

[0007] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0008] A wind power generation device comprises a rotating shaft and a plurality of impellers connected to the outer circumference of the rotating shaft, the rotating shaft being rotatable around its own axial direction, and the plurality of impellers being arranged in a circumferential array around the rotating shaft; the impeller comprises tapered blades and a connecting rod, the connecting rod being fixedly connected between the rotating shaft and the tapered blades, and the length extension direction of the tapered blades does not intersect with the rotating shaft; the end of the tapered blade close to the rotating shaft is a blade root end, and the end away from the rotating shaft is a blade tip end, and in the direction from the blade root end to the blade tip end, the outer diameter of the tapered blade gradually increases; a guide slope is also cut to form on the tapered blade, and the inclination direction of the guide slope is set at an angle to the length extension direction of the tapered blade; when the air flow blows on the tapered blade, a part of the air flow drives the tapered blade to rotate, and the other part of the air flow flows to another adjacent tapered blade under the guidance of the guide slope.

[0009] Furthermore, the guide slope is inclined from the tip end of the tapered blade toward the root end.

[0010] Furthermore, the guide slope includes a flared side for air to flow toward the guide slope, and a narrow side for air to flow out of the guide slope; the narrow side is located on a side of the guide slope close to the blade root end.

[0011] Furthermore, it also includes a support rod, a first collector slip ring installed above the support rod, and a generator rotatably arranged on the first collector slip ring; the rotating shaft is connected to the generator, and the generator is electrically connected to the first collector slip ring.

[0012] Furthermore, a solar film is pasted on the outer periphery of the impeller.

[0013] Furthermore, a second collector slip ring is provided on a side of the generator facing the impeller, and the solar film is electrically connected to the second collector slip ring.

[0014] Furthermore, a wind-fixing tail wing for automatic wind alignment is installed on a side of the generator facing away from the impeller.

[0015] An array-compensated solar-wind power generation device comprises a frame and the above-mentioned wind power generation devices distributed on the frame in an array manner.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The wind power generation device provided by the present invention comprises an impeller composed of tapered blades and connecting rods, the length extension direction of the tapered blades does not intersect with the rotation axis, a guide slope is cut on the tapered blades, and the inclination direction of the guide slope is set at an angle to the length extension direction of the tapered blades; when the air flow blows on the tapered blades, a part of the air flow pushes the tapered blades to rotate and then disappears, and the other part of the air flow flows to another adjacent tapered blade under the guidance of the guide slope to form a compensating wind, and the compensating wind will drive the middle part of the other tapered blade and push it to rotate. Therefore, each tapered blade will be subjected to two forces, one is given by the breeze, and the other is given by the compensating wind blown out by the previous tapered blade. Such an impeller design effectively solves the problems of small breeze collection and low efficiency of traditional wind power generation devices, so that the generator can be started at a lower wind speed to achieve efficient wind power generation.

[0018] 2. In the wind power generation device provided by the present invention, the outer diameter of the tapered blade gradually increases in the direction from the root end to the tip end of the blade, and the guide slope is structurally arranged to be inclined from the tip end to the root end of the blade. When the mass of the tapered blade is as small as possible, the guide slope can have a larger wind guide area, which is beneficial to blowing more compensating wind to adjacent tapered blades, thereby improving the efficiency of wind power generation.

[0019] 3. The wind power generation device provided by the present invention has a design in which the air flow passes through the guide slope and flows in from the expanded side and out from the narrow side, which is convenient for converging the air flow, and is conducive to more air flow forming compensating wind to blow to the next tapered blade, which is conducive to achieving breeze start-up.

[0020] 4. In the wind power generation device provided by the present invention, the generator is installed on the first collector slip ring, and the first collector slip ring is fixed on the support rod. In addition to the rotation function, the first collector slip ring can also conduct the electricity generated by the solar film and the generator.

[0021] 5. In the wind power generation device provided by the present invention, the solar film is pasted on the outer surface of the tapered blade, the second collector slip ring is installed in front of the generator, the solar film is connected to the second collector slip ring, and the electricity generated by the solar film is conducted through the second collector slip ring, avoiding the winding problem during the rotation process. Combining solar energy and wind energy to achieve dual-path coupled power generation is conducive to improving the comprehensive utilization efficiency of energy, and the method of pasting the solar film on the impeller can effectively reduce the footprint of the power generation device, making the power generation device more widely applicable.

[0022] 6. The wind turbine generator provided by the present invention can have a fixed-wind tail wing that can automatically face the wind, so that the natural wind can blow the impeller in a direction that is directly opposite to the impeller to drive it to rotate.

[0023] 7. The array-compensated solar-wind power generation equipment provided by the present invention has an array of wind power generation devices distributed on a frame, and the size and quantity can be adjusted according to actual working conditions and electricity needs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 An array-compensated solar-wind power generation device as shown in FIG. 4 includes a frame 10 and an array of wind power generation devices 20 distributed on the frame.

[0034] In this embodiment, the wind power generation device 20 includes three impellers 21, a solar film 22, a rotating shaft 23, a second collector slip ring 24, a generator 25, a fixed wind tail 26, a first collector slip ring 27 and a support rod 28. It can be understood here that the number of impellers 21 can also be set to four or more as needed.

[0035] like Figure 2As shown, the first collector slip ring 27 is installed above the support rod 28, the generator 25 is rotatably arranged on the first collector slip ring 27, and the generator 25 is electrically connected to the first collector slip ring 27. The rotating shaft 23 is connected to the side of the generator 25 facing the impeller 21, and the rotating shaft 23 is rotatably arranged around its own axis. The three impellers 21 are arranged in a circumferential array around the rotating shaft 23. The solar film 22 is pasted on the surface of the impeller 21, and the side of the generator 25 facing the impeller 21 is provided with a second collector slip ring 24, and the solar film 22 is electrically connected to the second collector slip ring 24. The electricity generated by the solar film 22 is conducted out through the second collector slip ring 24, avoiding the winding problem during the rotation of the rotating shaft 23. The fixed wind tail 26 is installed behind the generator 25, which plays an automatic wind-facing role. In addition to the rotation function, the first collector slip ring 27 can also conduct the electricity generated by the solar film 22 and the generator 25. This wind power generation device 20 combines solar energy and wind energy to achieve dual-path coupled power generation, which is beneficial to improving the comprehensive utilization efficiency of energy. In addition, by pasting the solar film 22 on the impeller 21, the footprint of the wind power generation device 20 can be effectively reduced under the condition of the same power generation capacity, so that the application range of the wind power generation device 20 is wider.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the impeller 21 is specifically a self-compensating wind impeller. The impeller 21 is composed of a tapered blade 211 and a connecting rod 212. The tapered blade 211 is cut from a plane of a tapered tube at a certain angle to the tube axis. The tapered blade 211 is rotated inward at a certain angle and fixed to the rotating shaft 23 with a connecting rod 212. Then, a plurality of impellers 21 are arranged in a circular array to form a self-compensating wind impeller.

[0037] Specifically, the length extension direction of the tapered blade 211 does not intersect with the rotation axis 23; the tapered blade 211 is cut to form a guide slope 211a, and the inclination direction of the guide slope 211a is set at an angle with the length extension direction of the tapered blade 211. When the air flow blows on the tapered blade 211, a part of the air flow pushes the tapered blade 211 to rotate and then disappears, and the other part of the air flow flows to another adjacent tapered blade 211 under the guidance of the guide slope 211a to form a compensation wind, which blows to the middle of another tapered blade 211 and pushes it to rotate. Therefore, each tapered blade 211 will be subjected to two forces, one is given by the breeze, and the other is given by the compensation wind blown out by the previous tapered blade 211a. Such an impeller design effectively solves the problem of small breeze collection and low efficiency of traditional wind power generation devices, so that the generator can be started at a lower wind speed to achieve efficient wind power generation.

[0038] Among them, one end of the tapered blade 211 close to the center or the rotation axis is the blade root end 211b, and the other end away from the rotation axis is the blade tip 211c. In the direction from the blade root end 211b to the blade tip 211c, the outer diameter of the tapered blade 211 gradually increases; the guide slope 211a is inclined from the blade tip 211c of the tapered blade 211 to the blade root end 211b. In this way, when the mass of the tapered blade 211 is as small as possible, the guide slope 211a can have a larger wind guide area, which is conducive to blowing more compensation wind to the adjacent tapered blades 211, which is convenient for achieving breeze start and improving wind power generation efficiency.

[0039] The guide slope 211a includes an expanded side 211d for air to flow toward the guide slope 211a, and a narrow side 211e for air to flow out of the guide slope; the narrow side 211e is located on the side of the guide slope 211a close to the blade root end 211b. This arrangement facilitates the narrow side 211e to gather air, which is conducive to more air to form compensating wind to blow to the next tapered blade 211, thereby achieving breeze start.

[0040] The wind power generation device and array compensation type solar-wind power generation equipment provided in this embodiment have the following advantages:

[0041] 1. The impeller 21 is a self-compensating wind impeller, which is composed of a tapered blade 211 and a connecting rod 212. The tapered blade 211 is cut from a plane of a tapered tube at a certain angle to the tube axis. The tapered blade 211 is rotated inward at a certain angle and fixed to the rotating shaft 23 by a connecting rod 212. A plurality of them are arranged in a circular array to form a self-compensating wind impeller. When wind blows on the impeller 21, part of the wind pushes the impeller 21 to rotate and then is lost, and the other part of the wind enters from the expanded side of the tapered blade 211 under the action of pressure and blows out from the narrow side. The blown compensating wind acts on the middle part of the next tapered blade 211 and pushes it to rotate. Therefore, each tapered blade is subjected to two forces, one is given by the breeze, and the other is given by the compensating wind blown out from the narrow side of the previous tapered blade 211. Such an impeller 21 design effectively solves the problem of small breeze collection and low efficiency of the breeze power generation device, so that the generator 25 can be started at a lower wind speed to achieve breeze power generation.

[0042] 2. The solar film 22 is pasted on the outer surface of the impeller 21, and the second collector slip ring 24 is installed in front of the generator 25. The solar film 22 is connected to the second collector slip ring 24, and the electricity generated by the solar film 22 is transmitted through the second collector slip ring 24, avoiding the winding problem during the rotation process. Combining solar energy and wind energy to achieve dual-path coupled power generation is conducive to improving the comprehensive utilization efficiency of energy, and the method of pasting the solar film 22 on the impeller 21 can effectively reduce the floor space of the wind power generation device 20, so that the application range of the wind power generation device 20 is wider.

[0043] 3. The wind-fixing tail wing 26 is installed behind the generator 25, which plays an automatic wind-proof role. The generator 25 is installed on the first collector slip ring 27, and the first collector slip ring 27 is fixed to the frame 10 through the support rod 28. In addition to the rotation function, the first collector slip ring 27 can also conduct the electricity generated by the solar film 22 and the generator 25.

[0044] 4. The wind power generation devices 20 are distributed in an array on the frame 10, and their size and quantity can be adjusted according to actual working conditions and power requirements.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
