Description

Specifications Method for providing electricity using wind energy to electric devices on freeway Technical field 5 This invention involves new energy, especially a method for providing electricity using wind energy to electric devices on freeway. Background technology 10 Existing wind energy generator having a vertical axis mainly use wind energy technology and rectification technology. They serve as the wind-solar complementary road lamp along the freeway or provide electricity for highway monitoring equipment. They are mostly provided on both sides of a freeway or applied for the electric equipment on both is sides of a freeway. Such method has disadvantages such as low wind energy efficiency and low wind energy generator full load rate etc. Invention content 20 The technical problems to be solved in this invention is to provide a method for providing electricity using wind energy to electric devices on freeway, with the focus on the deficiencies of the existing technology. According to one aspect of this invention, a method for providing 25 electricity using wind energy to electric devices on freeway is provided, comprising: providing wind energy generator having a vertical axis on freeways, and converting energy from the wind generated by the moving vehicles on the freeway into electricity, the position of the wind energy generator having a vertical axis including the middle of the freeway; 30 converting the unstable alternating current generated by the wind energy generator having a vertical axis into a stable direct current via a rectifying and filtering unit; outputting via a conversion circuit unit the direct current voltage outputted by the rectifying and filtering unit separately as a voltage necessary for a battery and a voltage necessary for a load, and providing electricity to the battery and the load, Alternatively, wind energy generator having a vertical axis includes: 5 Savonius wind energy generator having a vertical axis and/or H type wind energy generator having a vertical axis with straight blades. Alternatively, the position for wind energy generator having a vertical axis also includes both sides of freeway. Alternatively, supply to load includes: controlling the output current to 1m load via load control unit, where conversion circuit unit, load control unit and load are successively coupled. Alternatively, supply to load includes: controlling the on-off status of load circuit, via load control unit based on the time set and on-off status of load circuit so as to realize the control of load. is Alternatively, charging a battery includes: charging a battery by the conversion circuit unit via anti-reflux diode. Alternatively, the method for providing electricity using wind energy to electric devices on freeway also includes: discharging the surplus electricity by opening the unloading circuit of unloading unit when a 2o battery is fully charged if the electric energy is surplus; where conversion circuit unit, unloading unit and a battery are successively coupled. Compared with the existing technology, this invention has the following advantages: this invention provides a method that does not require 25 electricity access, only use the natural wind resources along the freeway and the wind energy created by moving vehicles on freeway in the isolated green belt in the middle of freeway to generate power, store the electric energy generated by wind energy via energy storage module, and provide the electricity supply for the electric equipment along the 30 freeway. This invention makes up for the deficiencies of the existing technology in the related field so that the road public electricity system itself has become a green energy loop control system. 2 of 8 Description of figures Figures 1-2 are the schematic diagrams of Savonius wind energy generator having a vertical axis; 5 Figures 3-4 are the schematic diagrams of H type wind energy generator having a vertical axis with straight blades; Figure 5 is a structure diagram of freeway wind energy generation system based on wind energy generator having a vertical axis provided according to an embodiment of this invention; io Figure 6 is a structure diagram of freeway wind energy generation system based on wind energy generator having a vertical axis provided according to another embodiment of this invention; Figure 7 is a flowchart of the method for providing electricity using wind energy to electric devices on freeway provided according to an 15 embodiment of this invention. Specific embodiments To better clarify the purpose, technical proposal and advantages of this invention, combined with the following figures, this invention is specified. 20 It should be understood that the specific embodiments described here are to explain this invention but not to limit this invention. The research conducted by the inventor shows that though the surroundings of freeway is broad with strong natural winds, the method 25 of placing wind energy generator on both sides of freeway doesn't take full advantage of the wind energy driven by moving vehicles on freeway. In addition, the natural wind energy is changing from time to time so that the generator unit is often under the operation, instead of full load and the distributed power supply will easily cause electricity overflow of a 3o battery, which is not conducive to the maximum utilization of wind energy. The research conducted by the inventor also shows that in order to take 3 of 8 full advantage of the wind energy driven by moving vehicles on freeway, wind energy generator having a vertical axis can be provided in the middle of freeway. According to different aerodynamic force that drives the wind energy generator having a vertical axis rotating, and there are 5 two kinds of energy generators: Savonius wind energy generator having a vertical axis (also known as S type wind energy generator) and H type wind energy generator having a vertical axis with straight blades. Savonius wind energy generator having a vertical axis, also known as S type wind energy generator, mainly uses the resistance caused by air to 1o drive the S type blades rotating so as to lead the rare earth permanent magnet generator to generate electricity. As shown in Figure 1-2, Savonius wind energy generator having a vertical axis generally comprises two axis staggered semi-terete blades, a brake unit and rare earth permanent magnet generator, There is also a 15 kind of energy generator with more than 3 blades overlapping for multiple layers to improve the power and avoid starting the dead zone. Its advantages are large pull-in torque and easy startup in weak wind, H type wind energy generator having a vertical axis is a lift type wind generator under the aerodynamic principle and acting with the lift force 20 caused by air. H type wind energy generator having a vertical axis comprises blades, a brake unit and rare earth permanent magnet generator. It mainly has 3-5 vertical line blades, fixed by quadrilateral or quinquangular hub, and a wind wheel comprising rods that connect blades, which drives the rare 25 earth permanent magnet generator to generate. For example, as shown in Figure 3, H type wind energy generator having a vertical axis comprises 3 blades 011 and spindle 012. As show in Figure 4, blades are in the aircraft airfoil shape. The resultant force arising from air flowing around blades forms the torque, driving the 30 blade wheel rotating. When the wind wheel rotates, it won't change its efficiency due to deformation. 4 of 8 In conclusion, if wind energy generator having a vertical axis is provided in the middle of freeway, it can take full advantage of the wind energy driven by moving vehicles on freeway to realize the stable supply of power, 5 According to an embodiment of this invention, a highway wind energy generation system based on wind energy generator having a vertical axis is provided. As shown in Figure 5, this system comprises: Wind energy generation module 11, consisting wind energy generator having a vertical axis, is used to convert wind energy into electricity; io Energy storage module 13 is used to store the electricity generated by the wind energy generation module; Load 14 includes the electrical load equipment along the freeway, such as advertising board, light box, road lamp, vehicle detector, variable message sign, weather detector, environment detector and camera Is equipment etc.; and Integrated control module 12, coupling/electrically connecting to the wind energy generation module 11, energy storage module 13 and load 14, is used to adjust the current output by the wind energy generation module 11 into the current separately suitable for the energy storage 20 module 13 and load 14, and the energy storage module 13 is suitable to supply electricity to load 14 via the integrated control module 12, According to another embodiment of this invention, the energy storage module 13 includes a battery for energy storage. 25 As shown in Figure 6, according to another embodiment of this invention, the integrated control module further comprises: Rectifying and filtering unit 121 converts the unstable Alternating current generated by the wind energy generator having a vertical axis into stable direct current via a rectifying and filtering unit; 30 Conversion circuit unit 122 outputs the DC voltage output by the rectifying and filtering unit as separately the voltage required by a battery and the voltage required by load by conversion circuit unit to 5 of 8 provide power supply for a battery and load, such as outputting the DC voltage out by the rectifying and filtering unit 121 via the conversion circuit unit uniformly as 12 V (the voltage required by a battery in this embodiment) to charge a battery; 5 Load control unit 123 receives the output of conversion circuit unit 122 to output stable current to the load and is able to control the size of output current. Wherein, load control unit 123 and a battery 14, load 13 constitute a series circuit, and as one unit in this series circuit, load control unit 123 1o can control the on-off status of load 13 by controlling its own on-off status. Meanwhile, the load control unit 123 equals to a resistance in a circuit and it can control the size of output current by controlling its own value of resistance. Also, the load in this embodiment is a DC load. If it is an AC load, it is 15 required to add a conversion circuit unit and a filter unit in the link of DC output to realize the conversion between DC and AC, and then connected to the load.
