Description

Technical Field

[0001] This utility model relates to the field of energy equipment technology, and in particular to a solar power generation device. Background Technology

[0002] With the global energy crisis and environmental pollution becoming increasingly severe, solar and wind energy, as renewable energy sources, are being used more and more widely. Photovoltaic modules and wind turbines, as core components of solar and wind power generation systems, directly affect the overall power generation efficiency of the system.

[0003] Traditional photovoltaic (PV) modules are mostly planar structures. While simple in structure, they suffer from drawbacks such as limited light-receiving area and low light energy utilization. To improve the power generation efficiency of PV modules, various improvement schemes have been proposed, such as using tracking brackets and concentrating PV modules. However, these schemes are often complex in structure and expensive, making large-scale application difficult.

[0004] To increase the light-receiving area and improve the utilization rate of solar energy, a frustum-shaped photovoltaic module has been proposed, such as the frustum-shaped photovoltaic module with a hexagonal or octagonal bottom surface disclosed in patent CN222089799U. This module features unlimited installation location and multi-angle, multi-directional light reception. However, because the photovoltaic panel is arranged on six or eight sides, some photovoltaic panels do not receive sunlight when receiving light. Therefore, the effective utilization rate of the entire photovoltaic module is approximately 59%-67%. Meanwhile, in some scenarios, such as when there are obstructions (e.g., buildings) blocking one side, this type of photovoltaic module is not suitable. Therefore, the market needs a solar power generation device that can reduce the impact of obstructions and has a high effective utilization rate of the photovoltaic panels.

[0005] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a solar power generation device with high photovoltaic panel utilization efficiency.

[0007] This utility model is achieved through the following technical solution:

[0008] A solar power generation device includes a main pole and several power generation mechanisms connected to the main pole. The power generation mechanisms include photovoltaic modules. The photovoltaic modules are prism-shaped structures or frustum-shaped structures with a rhomboid cross-section. The photovoltaic modules are composed of several photovoltaic units arranged around the outside of the main pole. The photovoltaic units are used to convert light energy into electrical energy.

[0009] As described above, the solar power generation device further includes a light source for illumination and / or supplemental lighting for the photovoltaic unit, the light source being positioned above the photovoltaic unit.

[0010] As described above, in a solar power generation device, the main rod is equipped with a cleaning device for spraying liquid onto the outer surface of the photovoltaic unit to clean the photovoltaic unit.

[0011] As described above, the solar power generation device further includes a wind turbine structure located at the upper end of the main pole and used for wind power generation.

[0017] As described above, in a solar power generation device, an electrical control room is provided at the lower part of the main pole, a first hanging lug is provided at the upper end of the main pole, a second hanging lug is provided above the electrical control room, and a cable for increasing the stability of the main pole is provided between the first hanging lug and the second hanging lug.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The photovoltaic module of this invention has a rhomboid prism or frustum pyramidal cross-section, which reduces the impact of shading, resulting in a larger light-receiving area, improved light energy utilization, and more uniform sunlight reception, reducing light energy loss and thus improving overall power generation efficiency. Compared to traditional hexagonal or octagonal frustum pyramidal photovoltaic modules, this design can generate more electricity under the same lighting conditions. The structure of this solar power generation device is relatively simple, requiring no complex tracking brackets or concentrating modules, reducing manufacturing costs and maintenance difficulty, facilitating large-scale application, and making it suitable for use in various environments. The photovoltaic units are arranged around the outside of the main pole, making the entire solar power generation device more space-efficient.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 7The solar power generation device shown includes a main pole 1 and several power generation mechanisms connected to the main pole 1. Each power generation mechanism includes a photovoltaic module 2, which is a prismatic or frustum-shaped structure with a rhomboid cross-section. The photovoltaic module 2 consists of several photovoltaic units 21 arranged around the outside of the main pole 1. These photovoltaic units 21 are used to convert light energy into electrical energy. The photovoltaic module 2 can be a frustum-shaped structure with a rhomboid cross-section, narrower at the top and wider at the bottom; alternatively, it can be a right prismatic structure with a rhomboid cross-section.

[0031] The photovoltaic module 2 of this utility model adopts a prism-shaped structure or a frustum-shaped structure with a rhomboid cross-section, which can reduce the influence of shading objects, thereby having a larger light-receiving area, improving the utilization rate of light energy, and also receiving sunlight more evenly, reducing the loss of light energy, thereby improving the overall power generation efficiency. The effective utilization rate of the photovoltaic panel of the entire photovoltaic module 2 reaches 75%-90%, and the overall power generation efficiency is high.

[0032] In one embodiment, such as Figure 6-7 As shown, when the solar power generation device of this scheme is installed on one side of an obstruction, the acute angle α of the rhomboid cross-section of the photovoltaic module 2 faces the obstruction, thereby reducing the obstruction of the photovoltaic module 2 and improving the light collection effect of the photovoltaic module 2. The obstruction can be a wall, fence, barrier, etc.

[0033] In one embodiment, the acute angle α of the rhomboid cross-section of the photovoltaic module 2 ranges from 1° ≤ α ≤ 60°, and the obtuse angle b of the rhomboid cross-section of the photovoltaic module 2 ranges from 120° ≤ b ≤ 179°. This effectively reduces the shadow coverage area of ​​the photovoltaic module 2 caused by obstructions, ensuring that more photovoltaic units 21 can receive sunlight, thereby improving the overall light collection effect. The design of angle α allows the photovoltaic module 2 to receive oblique light at a smaller angle when facing obstructions, maximizing the use of limited light resources and reducing light energy loss.

[0034] In one embodiment, the power generation mechanism further includes a light source 3 for illumination and / or supplemental lighting of the photovoltaic unit 21, the light source 3 being positioned above the photovoltaic unit 21. This device can achieve the effect of a street lamp by emitting light through the light source 3. Simultaneously, the light source 3 can also provide supplemental lighting to the photovoltaic unit 21 at night or in situations of insufficient light, enabling it to continue generating electricity, thereby extending the effective operating time of the photovoltaic module 2 and increasing the overall power generation. The light source 3 can be an energy-saving lamp such as an LED light, reducing energy consumption while providing supplemental lighting.

[0035] In one embodiment, an electrical control room 8 is provided at the lower part of the main pole 1. A cleaning device 4 is provided on the main pole 1 for spraying liquid onto the outer surface of the photovoltaic unit 21 to clean it. Specifically, the cleaning device 4 includes nozzles mounted on the main pole 1 or the assembly plate 11. The nozzles are connected to an air source and a water source via pipelines, and the pipelines control the spraying of water and air via electromagnetic pumps and solenoid valves. Further, the air source can be an air tank or air compressor located within the electrical control room 8, or it can be an external air tank or air compressor. The water source can be a water storage tank located within the electrical control room 8, or it can be an external water tank or a tap water network. Further, a water tank and a filter device can be provided at the lower part of the photovoltaic unit 21 to return the cleaning water or external rainwater to the water storage tank.

[0036] In one embodiment, the power generation mechanism further includes a wind turbine structure 5 located at the upper end of the main pole 1 for wind power generation. The wind turbine structure 5 can be the same as or similar to the wind power generation mechanism in patent number CN202411167317.4, entitled "A Wind Power Generation Device and its Wind Power Generation Control Method." Alternatively, the wind turbine structure 5 can be a conventional wind turbine available on the market. The electrical control room 8 or the main pole 1 is equipped with a battery for storing electrical energy. This device integrates solar and wind power generation functions, enabling complementary power generation under different weather conditions, thereby improving the continuity and stability of energy utilization. Whether in environments with abundant sunlight or strong winds, the device can generate electricity efficiently, reducing energy waste.

[0037] In one embodiment, the main rod 1 is provided with an assembly plate 11, and the lower end of the photovoltaic unit 21 is connected to the assembly plate 11. The main rod 1 is provided with a support member 12 for supporting the assembly plate 11, and a pressure strip 6 for pressing the photovoltaic unit 21 is connected to the support member 12. The support member 12 can be a support column, and the end of the pressure strip 6 is connected to the support member 12 by threaded fasteners or other connecting structures. Pressing the photovoltaic unit 21 with the pressure strip 6 enhances the structural stability of the entire solar power generation device, enabling it to withstand severe weather conditions such as strong winds, rain, and snow, and reducing damage caused by structural loosening or deformation. The assembly plate 11 can be connected to the main rod 1 and the support member 12 by threaded fasteners or other connecting structures. The photovoltaic module is composed of several photovoltaic units 21 and assembly plates 11 spliced ​​together.

[0038] Furthermore, the pressure strip 6 has slots 61 on both sides that mate with the side edges of the photovoltaic unit 21, and a thickened portion 62 between the two slots 61 to enhance the stress resistance of the pressure strip 6. The slots 61 on both sides of the pressure strip 6 can tightly engage with the side edges of the photovoltaic unit 21, ensuring the photovoltaic unit is firmly fixed to the main rod 1. This effectively prevents the photovoltaic unit 21 from loosening or shifting due to vibration, wind, or other external forces, improving the stability and reliability of the device. The thickened portion 62 between the two slots 61 significantly enhances the stress resistance of the pressure strip 6. The thickened portion 62 can withstand greater external forces, preventing the pressure strip from deforming or breaking due to long-term stress, thereby extending the service life of the pressure strip and ensuring the long-term stable fixation of the photovoltaic unit. The slots 61 make the installation of the photovoltaic unit 21 simpler. Simply embed the side edge of the photovoltaic unit 21 into the slot 61 for quick fixation, without the need for complex installation tools or steps. This design reduces installation difficulty and improves installation efficiency. Meanwhile, the pressure strip 6 can also cover the gap between the two photovoltaic units 21, making the appearance neater and more beautiful. While ensuring the fixing effect, it also improves the overall visual effect of the device.

[0039] The photovoltaic unit 21 described above includes a photovoltaic panel and a frame that connects the photovoltaic panel to the main rod 1. The slot 61 is adapted to the side edge of the frame.

[0040] In one embodiment, a top cover 7 is provided at the top of the main pole 1. At least two sets of power generation mechanisms are provided on the main pole 1, distributed vertically. A light source 3 for supplementing light to the uppermost photovoltaic module 2 is located at the lower part of the top cover 7, and a light source 3 for supplementing light to the lower photovoltaic module 2 is located above it on the assembly plate 11 of the adjacent photovoltaic module 2. This fully utilizes vertical space, enabling the deployment of more photovoltaic modules 2 within a limited footprint, significantly improving space utilization and power generation capacity. By providing light sources 3 at the lower part of the top cover 7 to supplement light to the uppermost photovoltaic module 2, and by providing light sources 3 on the assembly plate 11 of the lower photovoltaic module 2 to supplement light to the lower photovoltaic module 2, a multi-layer supplementary lighting function is achieved, ensuring that each photovoltaic module 2 can receive supplementary light under insufficient illumination conditions, thus improving overall power generation efficiency. The top cover 7 can be connected to the main pole 1 via threaded fasteners or other connecting structures.

[0041] Furthermore, the light source 3 is electrically connected to a control system that can control its activation to perform lighting or supplemental lighting work, and the photovoltaic unit 21 is electrically connected to the control system.

[0042] In one embodiment, the upper and lower ends of the photovoltaic unit 21 can be installed by hinges, so that the photovoltaic unit 21 can be flipped open to facilitate maintenance.

[0043] The main rod 1 can be cylindrical or a columnar structure with an N-sided cross-section, where N is greater than or equal to 3. Of course, the main rod 1 can also be a multi-faceted pyramidal rod or a conical rod.

[0044] In one embodiment, a functional box 71 is provided at the lower part of the top cover 7. The functional box 71 is equipped with a light source 3 or a disinfection nozzle for spraying disinfectant. The disinfection nozzle is connected to a storage tank for storing disinfectant via a pipe, and an electromagnetic pump is provided on the pipe. Of course, monitoring or other functional components can also be installed on the functional box to achieve more functions. The functional box 71 can be connected to the top cover 7 by threaded fasteners or other connection structures.

[0045] In one embodiment, the front side of the photovoltaic unit 21 is a light-transmitting glass plate, the back side of the photovoltaic unit 21 is a light-transmitting glass plate, and the solar cells of the photovoltaic unit 21 are located inside the double-sided glass plate; or the front side of the photovoltaic unit 21 is a light-transmitting glass plate, the back side of the photovoltaic unit 21 is a light-transmitting film, and the solar cells of the photovoltaic unit 21 are located inside the glass plate and the film.

[0046] The photovoltaic units 21 are connected in parallel to maintain a consistent voltage. This consistent voltage ensures that the photovoltaic module 2 is unaffected by weather changes; regardless of the individual power output of each photovoltaic unit 21, it can be fully utilized for efficient energy collection and application, thus preventing energy waste. Since winds are stronger at higher altitudes and weaker at lower altitudes, photovoltaic units 21 of different sizes can be arranged from top to bottom. When the size of each photovoltaic unit 21 differs, the number of cells inside will also differ. Voltage consistency is achieved by calculating the number of cells connected in series and parallel. For example, assuming each cell has a voltage of 0.6V and the total output voltage is 14.4V, and the three photovoltaic units 21 have 48, 72, and 96 cells respectively, the first photovoltaic unit 21 has 24 cells connected in series and 2 cells connected in parallel per circuit; the second photovoltaic unit 21 has 24 cells connected in series and 3 cells connected in parallel per circuit; and the third photovoltaic unit 21 has 24 cells connected in series and 3 cells connected in parallel per circuit. This ensures that the total output voltage of each photovoltaic unit 21 is the same, which is 14.4V.

[0047] In one embodiment, the upper end of the main rod 1 is provided with a first hanging lug 91, the upper part of the electrical control room 8 is provided with a second hanging lug 92, and a cable 93 for increasing the stability of the main rod 1 is provided between the first hanging lug 91 and the second hanging lug 92.

[0048] The solar power generation device of this utility model can also be installed on the median strip in the middle of the driveway, or on the sidewalk or green belt next to the driveway.
