Description

Technical Field

[0001] The utility model relates to the technical field of wind-solar power generation and energy storage, and in particular to a multi-axis tracking folding wind-sheltered tree-shaped wind-solar integrated power generation system. Background Art

[0002] The use of fossil fuels has also brought about serious environmental pollution and ecosystem damage. In recent years, humans have gradually realized the importance of energy to humans, and have become more aware of the damage to the environment and ecosystem during the use of conventional energy. In order to manage and alleviate the deteriorating environment, the development and utilization of renewable, pollution-free new energy sources have gradually become an important part of sustainable development.

[0003] Photovoltaic power generation has been widely promoted as a renewable, clean and efficient form of energy. In the navigation energy system, solar navigation lights that use photovoltaic power generation have emerged. When there is sufficient light, the solar panels generate current and voltage under the light to charge the battery. However, the lighting effect of this type of solar navigation light is easily affected by the environment, and the power generation efficiency of photovoltaic power generation fluctuates greatly: in continuous adverse weather conditions, insufficient solar power generation can easily cause over-discharge of the battery and light outage, affecting the performance of the battery or even damaging it; and solar power generation is greatly affected by the season, and the problem of insufficient solar power generation is particularly serious in winter and spring.

[0004] In order to improve power generation efficiency and stability, the prior art proposes a wind-solar hybrid power generation system. The wind-solar hybrid power generation system fully utilizes the complementarity of wind and solar energy resources and is a cost-effective new energy power generation system with good application prospects.

[0005] However, the existing wind-solar hybrid power generation system has the following problems:

[0006] 1. The overall structure is fixed, and it is impossible to flexibly adjust the on and off status of the wind power generation system and the photovoltaic power generation system according to the environmental characteristics of day and night, weather and seasons, resulting in low resource utilization. In addition, the wind-solar hybrid power generation system is usually in the on state for a long time, and the exposed solar panels are easily damaged in bad weather;

[0007] 2. Land occupation problem. Wind-solar hybrid power generation systems are generally complex in structure and occupy a large area. Due to the scarcity of offshore land resources, the large structure of wind-solar hybrid power generation systems hinders the popularization of wind-solar hybrid power generation systems in navigation energy application scenarios;

[0008] 3. High installation and maintenance costs and limited service life. Utility Model Content

[0009] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a multi-axis tracking folding wind-proof tree-shaped wind-solar integrated power generation system.

DETAILED DESCRIPTION

[0030] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs.

[0032] Embodiment 1

[0033] like Figure 1 As shown, this embodiment provides a multi-axis tracking folding wind-proof tree-shaped wind-solar integrated power generation system, comprising a tree trunk 1, a plurality of photovoltaic panel groups 2 arranged at different heights of the tree trunk, and a wind turbine 5 arranged at the top of the tree trunk 1;

[0034] Each photovoltaic panel group 2 includes two photovoltaic panel units 21 symmetrically distributed along the trunk 1; the photovoltaic panel unit 21 includes a bracket 211 and a photovoltaic panel; the photovoltaic panel unit 21 is connected to the trunk 1 through a lever arm assembly 22; the lever arm assembly 22 includes an electric push rod 222, which is used to adjust the photovoltaic panel unit 21 to fold upward, fold downward, and face the angle.

[0035] This embodiment is a wind-solar hybrid power generation system, which is a derivative product of the photovoltaic tree. It integrates wind power generation on the basis of realizing solar power generation. The overall structure is a tree-shaped structure, the bottom occupies a small area, and the overall structure is stable and balanced. It can be used in navigation scenes to withstand the invasion of sea breeze without swaying or falling.

[0036] The wind turbine 5 on the top of the trunk 1 is a vertical axis wind turbine that extends longitudinally, which is convenient for installation on the top of the wind-solar integrated power generation system, and its vertical axis blades rotate in a simple cylindrical shape, making it easier to receive wind energy from all directions. It uses the industry's top technology: a multi-layer, multi-blade breeze wind power generation system, with low starting wind speed, stable operation, stable all-weather power generation, and high power generation efficiency.

[0037] A plurality of support members 4 are arranged around the bottom of the trunk 1 to ensure that the system is stably fixed on the ground to prevent shaking or falling in windy weather.

[0038] The middle part of the trunk 1 is longitudinally distributed with photovoltaic panel groups 2, and each photovoltaic panel group 2 includes two photovoltaic panel units 21 that operate synchronously or independently. Figure 2 As shown, the photovoltaic panel unit 21 includes a bracket 211 and a photovoltaic panel, which is used to realize photovoltaic power generation. The bracket 211 includes an extension frame 2111 connected to the trunk 1, and the extension frame 2111 is hinged with the cross beam 3 set at different heights of the trunk 1 to limit the height of the photovoltaic panel group 2; the extension frame 2111 is provided with a horizontal brace 2112 and a vertical brace 2113 for installing the photovoltaic panel; a connecting beam 2114 is provided between the extension frames 2111, and the connecting beam 2114 is connected to a hinge bracket 2115; the hinge bracket 2115 is used to connect with the arm assembly 22.

[0039] Among them, Figure 3 As shown, the structure of the hinge bracket 2115 is a sheet metal structure with multiple nodes. The original multiple assembly nodes are completed through one bracket, which greatly reduces the material cost, production cost and assembly cost. Moreover, the assembly is convenient and stable, which greatly improves the strength of the assembly nodes, achieves horizontal and vertical, and ensures the straightness, parallelism, verticality and position requirements.

[0040] The lever assembly 22 includes an upper lever 221, an electric push rod 222 and a lower lever 223. The lower lever 223 is hinged to the trunk 1; the two ends of the electric push rod 222 are respectively hinged to the upper lever 221 and the lower lever 223; one end of the upper lever 221 is hinged to the hinge bracket 2115. The electric push rod 222 can drive the opening and closing between the upper lever 221 and the lower lever 223, driving the photovoltaic panel unit 21 to rotate 180 degrees around the crossbeam 3 to adjust the angle between the photovoltaic panel unit 21 and the trunk 1.

[0041] It should be understood that the electric push rod 222 can be implemented using conventional drive components in the art.

[0042] Since the power generation system of this embodiment has both the photovoltaic panel group 2 covering the solar panel and the wind turbine 5 capable of wind power generation, it combines the advantages of photovoltaic power generation and wind power generation; the photovoltaic power generation system and the wind power generation system and the coordination between the components can be adjusted according to the changes of day and night, weather and seasons, so that the power generation system as a whole can achieve a balance between ensuring maximum power generation and extending service life in different environments. Specifically:

[0043] (1) Day and night changes

[0044] At night, there is no available solar heat, the photovoltaic power generation system stops working, and the photovoltaic panel group 2 is folded and retracted to avoid unnecessary use losses and to prevent strong winds at night from invading the photovoltaic panels and affecting the performance of solar energy conversion; the wind turbine 5 is turned on, and wind power generation is mainly used at night.

[0045] The photovoltaic panel group 2 can be folded and retracted, and can be folded upward, at which time the two photovoltaic panel units 21 in each photovoltaic panel group 2 are opposite to each other, so as to protect the photovoltaic panel from direct damage to the photovoltaic panel by the external environment, such as raindrops washing or branches scratching; it can also be folded downward, at which time the backs of the two photovoltaic panel units 21 in each photovoltaic panel group 2 are opposite to each other, and the photovoltaic panels are all facing outward. In this embodiment, it is preferred that the photovoltaic panel units are folded and retracted downward at night, so as to gradually adjust the angle of the photovoltaic panel units toward the sunlight when the sun rises.

[0046] During the day, when the light intensity is sufficient, photovoltaic power generation is mainly used, and at least one group of photovoltaic panels 2 is turned on, and the wind turbine 5 may not be started to reduce its use loss, thereby ensuring a balance between power generation and service life.

[0047] (2) Weather changes

[0048] In case of bad weather, such as strong winds, wind power generation is mainly carried out, the wind turbine 5 is turned on, and the photovoltaic panel group 2 is preferably folded up and retracted.

[0049] At the same time, in order to protect the normal use of the power generation system, the wind turbine 5 is stopped when the wind force exceeds level 12. Since the present invention can intelligently convert the AC power of wind power and the DC power of photovoltaic power into grid-connected power and store energy when the system is generating electricity normally, power supply can still be guaranteed in extremely bad weather.

[0050] It should be understood that the conversion, grid connection and energy storage are achievable with existing technologies.

[0051] If it is rainy or snowy, the electric push rod 222 can drive the upper force arm 221 to quickly extend and retract, that is, simulate a shaking action to shake off snow and rain.

[0052] (3) Seasonal changes

[0053] The electric push rod 222 can sense the external weather conditions through the wind speed sensor and the light sensor (not shown in the figure) to track the environment and adjust the angle and the number of photovoltaic panel units 21. The two photovoltaic panel units 21 of each photovoltaic panel group 2 can move synchronously or independently to ensure the best light angle.

[0054] In summer and autumn, the daytime sunshine time is long and the light intensity is sufficient, photovoltaic power generation is mainly used, and the wind turbine 5 can be kept off to reduce its use loss; in spring and winter, when the solar power generation power is insufficient, it is often the time when wind energy is most abundant. At this time, wind power generation is mainly used, and the wind turbine 5 is turned on in combination with a small number of photovoltaic panels 2, so as to ensure a balance between power generation power and service life.

[0055] This embodiment integrates the advantages of multi-axis tracking folding wind-proof tree-shaped photovoltaic power generation and vertical axis power generator, and brings together the advantages of the two. The wind-solar complementary power generation system can cater to the characteristics of day and night, weather and seasonality in navigation applications, and improve power generation efficiency and resource utilization.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
