Description

Technical Field

[0001] This invention relates to the fields of renewable energy and power generation technology, and in particular to a simulated landscape tree wind energy utilization system based on deformation power generation. Background Technology

[0002] Wind power is a renewable energy source with enormous reserves, accounting for a significant proportion of the global energy mix. However, with the widespread commercial use and development of large wind turbines, the technical requirements for horizontal axis wind turbines are becoming increasingly stringent, leading to higher power generation costs and making it difficult to compete with traditional energy sources. This severely restricts the sustainable development of wind power. Furthermore, the development of large wind farms has gradually revealed its environmental and biological impacts. Statistics show that 600,000 birds die annually under wind turbines, and noise and visual pollution also cause considerable problems.

[0003] At the same time, with the rapid development of urbanization, large-scale wind farms cannot be widely used in densely populated cities. Due to the boundary layer effect of wind, wind turbine generators are inefficient in densely populated cities.

[0004] With the continuous development of society, urban greening and environmental protection are receiving increasing attention. Therefore, artificial landscape trees, as an indispensable part of urban greening, exist in a considerable number in cities. However, artificial landscape trees currently serve only a basic aesthetic purpose, and their other functions have not yet been fully utilized.

[0005] In conclusion, if simulated landscape trees can be used to address the problem of low wind energy utilization, and if they can be fully utilized, the utilization rate of new energy sources in cities can be further improved. Existing technologies do not yet have a method to improve the utilization rate of new energy sources in cities using this approach. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simulated landscape tree wind energy utilization system based on deformation power generation.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A wind energy utilization system based on deformation-generated simulated landscape trees includes a simulated landscape tree and a complete set of power equipment connected to the simulated landscape tree for collecting electrical energy. The simulated landscape tree includes a treetop, tree branches, and leaves. The outer wall of the treetop is provided with a tile-shaped flexible piezoelectric material component. The tree branches are composed of flexible, slender piezoelectric material components. One end of the flexible, slender piezoelectric material component is connected to the treetop, and the other end is connected to the leaves. The flexible, slender piezoelectric material component is internally connected to the treetop via a connecting wire, which is connected to the complete set of power equipment. The tile-shaped flexible piezoelectric material component is connected to the complete set of power equipment via the connecting wire.

[0009] Preferably, the bending arc of the tile-shaped flexible piezoelectric material is 90°, and the tile-shaped flexible piezoelectric material is evenly arranged on the outer wall of the treetop of the simulated landscape tree.

[0010] Preferably, the length and area of ​​the tile-shaped flexible piezoelectric material component match the size of the treetop of the simulated landscape tree.

[0011] Preferably, the amplitude of the flexible elongated piezoelectric material component deforms within the maximum allowable deviation angle, and the angle between the maximum allowable cross-sectional axis and the deformation direction is 30°.

[0012] Preferably, the vertical axis of the flexible, slender piezoelectric material component coincides with the axis of the treetop of the simulated landscape tree to which it is attached.

[0013] Preferably, the total area of ​​the two different types of piezoelectric materials, namely the tile-shaped flexible piezoelectric material and the flexible slender piezoelectric material, is 60%-80% of the area of ​​the simulated landscape tree that is prone to deformation.

[0014] Preferably, one end of the flexible, slender piezoelectric material is connected to the treetop of the simulated landscape tree in a spiral manner, and the other end is connected to the leaves of the simulated landscape tree in a spiral manner.

[0015] Preferably, the flexible, slender piezoelectric material component has a columnar structure.

[0017] Preferably, the outer layer of the flexible elongated piezoelectric material component and the outer layer of the tile-shaped flexible piezoelectric material component are provided with simulated tree bark.

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

[0019] I. This invention utilizes the deformation of treetops caused by wind blowing over landscape trees, which in turn causes piezoelectric material components on the treetop surface and branches made of piezoelectric material to deform and generate current through the piezoelectric effect. No additional power generation equipment is required, and existing urban items are utilized, thus improving the economic efficiency of piezoelectric materials.

[0020] Second, this invention is suitable for large-scale use in densely populated cities with buildings, solving the problem that existing wind turbines cannot make reasonable use of wind energy in cities, and does not affect the urban ecology, and can make full use of the simulated landscape trees in the city.

[0021] Third, the bending arc of the tile-shaped flexible piezoelectric material component of the present invention is 90°. The length and area of ​​the tile-shaped structure of the tile-shaped flexible piezoelectric material component match the size of the treetop of the simulated landscape tree. The amplitude of the flexible slender piezoelectric material component deforms within the maximum allowable deviation angle. The angle between the maximum allowable cross-sectional axis and the deformation direction is 30°. Furthermore, the vertical axis of the flexible slender piezoelectric material component coincides with the axis of the treetop of the simulated landscape tree to which it is combined. The structure, position and deformation angle of the two piezoelectric material components can achieve an effective and good match with the simulated landscape tree, which is conducive to making full use of the simulated landscape tree in the city.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0033] Example

[0034] This invention relates to a wind energy utilization system for simulated landscape trees based on deformation-induced power generation. The system's pulsed electrical energy originates from branches made of flexible, tile-like piezoelectric material covering the treetops and flexible, slender strip-shaped piezoelectric material. A certain amount of piezoelectric material is placed on the treetops and connected by wires that pass through the surface of the landscape tree and connect within its internal space. The energy is then collected into a combiner box via a rectification and filtering system, and subsequently used to charge a battery for use in urban public facilities.

[0035] like Figures 1-6 As shown, this invention relates to a wind energy utilization system based on deformation-generated simulated landscape trees. The system includes a tile-shaped flexible piezoelectric material component 3, a simulated landscape tree 9, and a complete set of power equipment. The complete set of power equipment includes a rectifier, filter, and combiner device 6 and an energy storage capacitor 7. The simulated landscape tree 9 consists of simulated landscape tree branches 2, simulated landscape tree tree tips, and simulated landscape tree leaves 8.

[0036] The simulated treetop 2 is a cylindrical hollow structure. A tile-shaped flexible piezoelectric material component 3 is fixed to the outer surface of the simulated treetop 2. This component is a tile-shaped thin-film piezoelectric material, which facilitates a tight fit with the cylindrical simulated treetop 2 and allows for the stacking of similar thin-film piezoelectric materials to increase power generation and wind energy utilization. The outer layer of the tile-shaped flexible piezoelectric material component 3 is covered with a bark-like structure. The bending radius of the tile-shaped flexible piezoelectric material component 3 is 90° (1 / 4 circle). Viewed in cross-section of the simulated treetop 2, with the treetop's axis as the origin, they are evenly distributed horizontally on the outer wall of the simulated treetop 2. The length and area of ​​the tile-shaped structure depend on the dimensions of the simulated treetop 2. The tile-shaped flexible piezoelectric material component 3 is connected to a rectifier-filter-combiner device 6 via connecting wires 5, and the rectifier-filter-combiner device 6 is connected to an energy storage capacitor 7. The inner layer of the simulated treetop 2 is equipped with flexible rubber to further improve its deformation capacity.

[0037] The branches of the simulated landscape tree are composed of a flexible, slender piezoelectric material component 1. Specifically, this invention uses the flexible, slender piezoelectric material component 1 to replace the branches of the simulated landscape tree 9. One end of the flexible, slender piezoelectric material component 1 is connected to the tip of the simulated landscape tree 2 via a spiral connection. This connection can be achieved using a fastening threaded structure 4, which can employ both external and internal threads. For example, one end of the flexible, slender piezoelectric material component 1 has an external thread, and the end of the simulated landscape tree tip 2 connected to it has a matching internal thread. The vertical axis of the flexible, slender piezoelectric material component 1 should coincide with the axis of the connected simulated landscape tree tip 2. The other end of the flexible, slender piezoelectric material component 1 is connected to the leaves 8 of the simulated landscape tree using a spiral connection. The outer layer of the flexible, slender piezoelectric material component 1 is covered with simulated bark for protection.

[0038] The flexible, slender piezoelectric material component 1 is internally connected to the treetop 2 of a simulated landscape tree via connecting wires 5. Connecting wires 5 are connected to a rectifier, filter, and combiner device 6, which is connected to an energy storage capacitor 7. The amplitude of the flexible, slender piezoelectric material component 1 deforms within the maximum allowable deviation angle, which is 30°. The deviation angle is defined as the angle between the cross-sectional axis and the deformation direction.

[0039] The piezoelectric materials used in the two different types of tile-shaped flexible piezoelectric material component 3 and flexible slender piezoelectric material component 1 can be existing piezoelectric materials. The proportion (including coverage and replacement rate) of the two different types of piezoelectric materials in the simulated landscape tree 9 that are prone to deformation (deformation criterion: the branches of the simulated landscape tree can deform under a 3-4 level wind) is 60%-80%.

[0040] The working principle of this invention is as follows:

[0041] The system of this invention generates wind power based on deformation. It utilizes the aerodynamic effect of wind energy, which is difficult to utilize in cities, on simulated landscape trees. The wind causes the branches (flexible, slender strip-shaped piezoelectric material components) of the simulated landscape trees to deform, thereby causing the piezoelectric material on the branches to generate pulsed electrical energy through the piezoelectric effect. The pulsed electrical energy is then rectified, filtered, and combined by a current-collecting device and fed into an energy storage capacitor.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
