Description

Technical Field

[0001] This utility model relates to the field of wind-solar hybrid power generation technology, specifically to a wind-solar hybrid power generation device. Background Technology

[0002] Wind-solar hybrid power generation is a combined power generation system that utilizes both wind and solar energy. In areas where both solar and wind energy are abundant, wind-solar hybrid power generation equipment can be installed to collect wind and solar energy for power generation, thereby improving the utilization rate of clean energy. However, in order to meet the needs of wind power generation, wind-solar hybrid power generation equipment is generally installed at a certain height. Therefore, scaffolding or ladders are required to maintain the solar power generation components. To address this, a wind-solar hybrid power generation equipment is proposed. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a wind-solar hybrid power generation device.

[0004] The present invention proposes a wind-solar hybrid power generation device, including a support guide rod, wherein a wind power generation device is fixedly connected to the top of the support guide rod by a support rod, and a solar power generation component is provided on the front of the support guide rod;

[0005] The support guide rod is internally equipped with a drive lifting assembly for raising and lowering the solar power generation module. The drive lifting assembly includes a transmission chain, with a second sprocket meshing on the inner wall near the top end of the transmission chain, and a first sprocket meshing on the inner wall near the bottom end. A guide slider is fixedly connected to the outer wall of the transmission chain on one side, and the guide slider is fixedly connected to the back of the solar power generation module via a connecting frame. A worm gear is fixedly connected to the first sprocket via a connecting rod, and a worm is meshed on the bottom surface of the worm gear.

[0006] The front of the support guide rod is provided with a guide groove, and the inner wall of the guide groove is slidably connected to the outer wall of the guide slider.

[0007] A further improvement of the present invention is that the connecting frame includes a locking plate, one side of which is fixedly connected to one end of a guide slider, and the other side of which is fixedly connected to a docking frame, and the side of the docking frame away from the locking plate is fixedly connected to the back of the solar power generation module.

[0008] A further improvement of this utility model is that: the bottom surface of the docking frame is fixedly connected to an inclined support frame, and the bottom end of the inclined support frame is fixedly connected to the side of the card limiting plate near the bottom end.

[0009] A further improvement of this utility model is that a drive motor is fixedly connected to one end of the worm gear.

[0010] A further improvement of the present invention is that both sprocket two and sprocket one are rotatably connected to the inner wall of the support guide rod via a bearing seat.

[0011] A further improvement of this utility model is that an auxiliary rotating disk is fixedly connected to the other end of the worm gear.

[0012] The wind power generation device includes a vertically arranged main wind turbine shaft, with a four-bladed wind turbine fixedly connected to the top of the main wind turbine shaft. The main wind turbine shaft is connected to the rotor shaft of a generator via a speed-increasing gearbox, and the generator is fixedly installed in a nacelle at the top of a support rod. The solar power generation module includes multiple monocrystalline silicon solar panels connected in series, each with heat dissipation fins on its back. The solar panels are connected to a connecting frame via a fixing plate. The output terminals of both the wind power generation device and the solar power generation module are connected to the same combiner box, which is connected to an energy storage battery pack via an inverter. During the day when there is sufficient sunlight, the solar power generation module generates electricity first, and excess energy is stored in the energy storage battery pack. At night or when there is insufficient sunlight, if the wind speed reaches the start-up threshold, the wind power generation device starts working, and the generated electricity and the electricity stored in the energy storage battery pack jointly power the load, realizing wind-solar complementary power generation.

[0013] The wind-solar hybrid power generation device proposed in this utility model has the following technical effects:

[0014] 1. This utility model provides a wind-solar hybrid power generation device. By driving a motor or manually rotating an auxiliary turntable, the worm gear, worm wheel, sprocket, and transmission chain can be driven to operate, achieving the raising and lowering of the solar power generation modules. When maintenance is required, the solar power generation modules can be lowered to a suitable height for easy operation by staff, greatly improving the convenience of maintenance and reducing its difficulty and cost.

[0015] 2. This utility model provides a wind-solar hybrid power generation device. The guide slider moves vertically under the restriction of the guide groove, ensuring the stability of the solar power generation module during the lifting process. The locking plate slides in close contact with the outer wall of the support guide rod, further enhancing the stability of the structure. The inclined support frame connects the docking frame and the locking plate, reinforcing the connecting frame structure and making the solar power generation module more stable and reliable during operation.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, this utility model provides a wind-solar hybrid power generation device, including a support guide rod 1, a wind power generation device 5 fixedly connected to the top of the support guide rod 1 by a support rod, and a solar power generation component 4 provided on the front of the support guide rod 1.

[0025] The guide rod 1 houses a drive lifting assembly 3 for raising and lowering the solar power generation module 4. The drive lifting assembly 3 includes a transmission chain 12. A second sprocket 11 meshes with the inner wall of the transmission chain 12 near its top end, and a first sprocket 10 meshes with the inner wall of the transmission chain 12 near its bottom end. A guide slider 14 is fixedly connected to the outer wall of the transmission chain 12 near one side. The guide slider 14 is fixedly connected to the back of the solar power generation module 4 via a connecting frame 6. A worm gear 9 is fixedly connected to the first sprocket 10 via a connecting rod, and a worm 8 meshes with the bottom surface of the worm gear 9.

[0026] The front of the support guide rod 1 is provided with a guide groove 2, and the inner wall of the guide groove 2 is slidably connected to the outer wall of the guide slider 14. The transmission chain 12 can be made of high-strength alloy steel with a material of 40Mn and a pitch of 15.875mm. It can withstand large tensile forces, ensuring stable operation when the solar power generation module is heavy, and it meshes well with the sprocket to reduce wear and jamming.

[0027] Example 2

[0028] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the connecting frame 6 includes a locking plate 15, one side of the locking plate 15 is fixedly connected to one end of the guide slider 14, and the other side of the locking plate 15 is fixedly connected to a docking frame 16, and the side of the docking frame 16 away from the locking plate 15 is fixedly connected to the back of the solar power generation module 4.

[0029] An inclined support frame 17 is fixedly connected to the bottom surface of the docking frame 16. The bottom end of the inclined support frame 17 is fixedly connected to the side of the locking plate 15 near the bottom end. The inclined support frame 17 is made of aluminum alloy 6061-T6, which has high strength and good corrosion resistance.

[0030] One end of the worm gear 8 is fixedly connected to the drive motor 7. If the solar power module weighs 80 kg, a 750W YE2 series three-phase asynchronous motor can be selected to ensure smooth lifting and lowering of the module. This model of motor has high efficiency and good starting performance, which can meet the requirements for smooth lifting and lowering of the solar power module.

[0031] Both sprocket 2 11 and sprocket 1 10 are rotatably connected to the inner wall of the support guide rod 1 via a bearing seat.

[0032] An auxiliary rotating disk 13 is fixedly connected to the other end of the worm gear 8.

[0033] The drive motor 7 can be controlled by an automated control system, which uses temperature sensors and current sensors installed on the solar power module. When the temperature sensor detects that the solar power module temperature exceeds 70°C, or the current sensor detects an abnormal current, the system automatically sends a signal to the controller of the drive motor 7, starting the motor to lower the solar power module for inspection and maintenance. Simultaneously, it is equipped with a wireless communication module, supporting remote control via a mobile app or computer software. Operators can remotely operate the raising and lowering of the solar power module within a 500-meter range.

[0034] The working principle of this wind-solar hybrid power generation equipment will be explained in detail below.

[0035] like Figure 1-4 As shown, when maintenance is required on the solar power generation module 4, the drive motor 7 is started by connecting the power supply, or the auxiliary rotating disk 13 is manually rotated, which in turn drives the worm gear 8 to rotate. The worm gear 8 then drives the worm wheel 9 to rotate clockwise, which in turn drives the sprocket 10 to rotate. During the clockwise rotation of the sprocket 10, the transmission chain 12 will start to rotate. Under the rotation of the transmission chain 12, the guide slider 14 will start to move the solar power generation module 4 downward through the connecting frame 6.

[0036] When the solar power generation module 4 is lowered to a suitable height, the rotation of the worm gear 8 can be stopped. At this time, the solar power generation module 4 has reached a height that is convenient for the staff to operate.

[0037] During the lifting and lowering process, the guide slider 14 will maintain vertical movement under the constraint of the guide groove 2, while the locking plate 15 will fit against the outer wall of the support guide rod 1, forming a sliding connection. The support guide rod 1 has inwardly recessed grooves on all four sides.

[0038] Buffer structures can be installed at both ends of the guide slider 14. If the solar power generation module has a high lifting speed, such as 0.8 m / s, a spring buffer structure can be installed at both ends of the guide slider 14. A compression spring made of 65Mn material with a wire diameter of 5 mm, an outer diameter of 30 mm, and 10 effective coils can be used to provide a large buffer force and ensure the safe operation of the equipment. If high requirements are placed on operational stability and noise control, a rubber buffer structure can be used. A 10 mm thick nitrile rubber buffer pad with a Shore A50 hardness can be attached to both ends of the guide slider 14 to effectively absorb vibration and noise.

[0039] The guide groove 2 on the front of the support guide rod 1 cooperates with the guide slider 14, which is fixed to the solar power generation module 4 via the connecting frame 6. When the drive lifting assembly 3 moves the guide slider 14 within the guide groove 2, the guide groove 2 restricts the guide slider 14 to move only in a specific direction, thereby guiding and initially positioning the lifting of the solar power generation module 4, ensuring that it moves up and down along the front of the support guide rod 1 without lateral deviation.

[0040] The transmission system, consisting of sprocket 10, sprocket 11, and drive chain 12, can precisely control the movement of drive chain 12 under the action of drive motor 7. Since guide slider 14 is fixed on drive chain 12, the lifting and lowering position of solar power generation module 4 can be controlled relatively accurately. However, this requires a high meshing precision between the sprockets and drive chain 12 to ensure the accuracy of transmission.

[0041] The meshing transmission between the worm 8 and the worm wheel 9 has a certain degree of self-locking. When the drive motor 7 stops rotating, the worm wheel 9 and worm 8 mechanism can maintain its current position, preventing the solar power generation module 4 from sliding down or moving on its own due to gravity or other factors, thus playing a role in positioning and locking.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
