Description

Technical Field

[0001] The present invention relates to the technical fields of environmental protection energy and green power, and a power generation method and device based on renewable energy. Background Art

[0002] In recent years, in order to reduce global environmental pollution, countries have vigorously developed green power mainly based on wind power and photovoltaics, and advocated the use of new energy. Against this background, environmentally friendly and energy-saving consumer goods represented by new energy vehicles have emerged! Although new energy vehicles use electricity as a clean energy source and have the effect of reducing environmental pollution, the current new energy vehicles are limited in driving range due to insufficient battery energy storage. In this regard, this is a major drawback for new energy vehicles.

[0003] Some people have proposed using a traditional wind turbine to generate electricity for a vehicle during driving. However, the traditional wind turbine will cause a certain direct resistance to the vehicle moving forward, and the exposed fan also poses a significant safety risk. Although there are already patent documents in the prior art that can change the wind direction, such as the patent number: "201810212060.8" titled: "Variable-direction Convex Airfoil Power Generation Device", which can solve the safety hazard of the exposed fan, this simple variable-direction power generation device only aims to solve the problem of the exposed fan and does not consider efficiency and its applicable scenarios. Therefore, its efficiency is relatively low and its applicable scenarios are limited.

[0004] However, during the inventor's research on different airfoil aircraft, it was found that the airfoil has the characteristics of small resistance, can reduce the resistance caused by the oncoming wind during driving, and reduce the safety hazard caused by the exposed fan.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0021] An embodiment of the present invention provides a power generation method based on renewable energy. Figure 1This is the overall framework diagram of a power generation method based on renewable energy according to an embodiment of the present invention. As Figure 1 shown, a power generation method based on renewable energy according to an embodiment of the present invention includes: Step S101, establish a lift channel between the upper and lower surfaces of the first airfoil; the lift channel is kept consistent with the lift direction of the first airfoil; Step S102, set one or more fans in the lift channel; Step S103, then drive the wind turbine by the wind in the lift channel to convert wind energy into electrical energy.

[0022] Normally, traditional wind power equipment is fixedly installed and used, and is not installed on a movable object to move therewith (for example: installed on the roof of a car and moving forward with the driving of the car); taking the movable object as a car, if the traditional wind power equipment is installed on the roof of the car, due to the relatively high height of the traditional wind power equipment, there will be obvious instability during the driving of the car, and it may even break and fall during high-speed driving, causing potential safety hazards; at the same time, because the traditional wind power equipment is not designed in a streamlined shape, when used on the roof of a car, it will increase the resistance of the car against the headwind during driving and consume more energy. Figure 2 This is a schematic diagram of the application scenario of hanging and installing on the top of a car for a power generation method based on renewable energy according to an embodiment of the present invention. In the embodiment of the present invention, through the streamlined design of the airfoil, using the pressure difference between the upper and lower surfaces of the airfoil, guide and change the direction of obtaining kinetic energy, reduce the direct wind resistance in the front, and enhance the stability during movement; and keep the lift channel consistent with the lift direction of the first airfoil, placing it on another airfoil (or it can also be placed on the roof of the car) can improve the lift, and at the same time can reduce the starting wind speed of the wind power equipment, enabling it to operate and generate electricity at low wind speeds; in addition, one or more fans can be set in the lift channel. When the fans in the lift channel start to rotate, an upward lift will be generated, and at the same time, part of the gravity can be offset; if other fans (including: exhaust fans, etc.) are also set in the lift channel, accelerate the intake of air from below and exhaust from above, which can indirectly increase the lift; among them, the one or more fans can be turbine fans, ordinary fans, or other fans. Specifically, whether to choose one or more fans and what type of fan to choose depends on the space of the lift channel and whether the purpose of increasing the efficiency can be achieved.

[0023] According to an implementation manner of a power generation method based on renewable energy, the lift in the lift channel is increased by changing the angle of attack of the first airfoil. The embodiment of the present invention utilizes the characteristic of the relationship between the lift of the airfoil and the angle of attack to increase the lift in the lift channel, so as to achieve the purpose of reducing the starting wind speed of power generation and improving the power generation efficiency.

[0024] According to an embodiment of a power generation method based on renewable energy, the lift channel is configured as a fluid acceleration channel with a Venturi effect. The fluid is inhaled from the lower inlet, accelerated through the narrow section, and then released from the upper outlet. The lift channel in the embodiment of the present invention belongs to the channel design of the Venturi effect. The fluid (such as air) is inhaled through the lower inlet, accelerated at the narrow section in the middle, and then discharged from the upper outlet to achieve the purpose of accelerating the fluid passing through the lift channel.

[0025] According to an embodiment of a power generation method based on renewable energy, a second airfoil is provided below the first airfoil. In the embodiment of the present invention, by referring to biplanes and ground effect, the lift in the lift channel is increased; the upward suction force on the upper surface of the second airfoil is increased and conducted to the lift channel and inhaled into the lift channel together to increase the lift; as long as it has the characteristics of an airfoil and can provide upward suction force, it can be used as the second airfoil; since the car roof is designed as an airfoil to reduce wind resistance during driving, such a car roof can be used as the second airfoil, but for some car roofs with less obvious airfoil characteristics or non-airfoil designs, in order to obtain better lift effects, the second airfoil needs to be reselected; in terms of manufacturing and use, the first airfoil and the second airfoil can be manufactured and used together, or the first airfoil can be manufactured first and then installed on the second airfoil for use; in either case, the second airfoil can be used to increase the lift; specifically, due to different vehicle models and different first airfoils, the front-back position and height setting of the first airfoil and the second airfoil may be different, but the setting standard is to minimize or eliminate the interference between the first airfoil and the second airfoil to provide greater lift for the lift channel, thereby improving the overall power generation efficiency.

[0026] According to an embodiment of a power generation method based on renewable energy, a support base is provided below the first airfoil, and the support base can guide the oncoming wind to the air inlet of the lift channel. In the embodiment of the present invention, by providing a support base below the first airfoil, not only the stability of the first airfoil can be increased, but also the angle of attack of the first airfoil can be maintained stable, increasing the lift in the lift channel; in addition, the support base can also be provided between the first airfoil and the second airfoil to obtain better effects.

[0027] According to an embodiment of a power generation method based on renewable energy, the support base divides the lower surface of the first airfoil into two parts, the front part being the part containing the lift channel, and the rear part being the part without the lift channel; and, a plurality of small holes can be provided on the rear part of the lower surface and / or both side surfaces of the first airfoil. Under the action of the pressure difference, the fluid will be sucked in from the small holes and guided to the lift channel to be accelerated. In the embodiment of the present invention, a support base is provided below the first airfoil, and a plurality of small holes can be respectively provided on the rear part of the lower surface and both side surfaces of the first airfoil. Under the action of the pressure difference, the fluid will be sucked in from the small holes and guided to the lift channel to be accelerated, so as to further increase the lift and improve the efficiency.

[0028] According to an embodiment of a power generation method based on renewable energy, a semi-circular cover is provided above the first airfoil; the semi-circular cover is connected to the first airfoil or the second airfoil to form a fluid acceleration annular channel. In the embodiment of the present invention, the semi-circular cover is connected to the first airfoil or the second airfoil to form an annular fluid acceleration channel. When the incoming wind passes through this channel, it will be accelerated, and the wind discharged from the lift channel will also be sucked, thereby indirectly accelerating the fluid flow in the lift channel again; in addition, the embodiment has unexpected technical effects. For example: after the wind passes through the acceleration channel, the disordered wind outside becomes parallel wind. In this way, the lift direction of the first airfoil can be kept stable, and the lift of the lift channel will be stable, and it can be applied to the installation on non-movable objects (such as: the roof, or when the car is parked, that is, when it is not moving). Compared with the prior art, the present application can obtain parallel wind better, determine the lift direction, so the efficiency is higher.

[0029] According to an embodiment of a power generation method based on renewable energy, the upper surface of the semi-circular cover can be a photovoltaic module, or a photovoltaic module is provided above the semi-circular cover. In the embodiment of the present invention, by providing a photovoltaic module above the semi-circular cover, or directly using the photovoltaic module as the upper surface of the semi-circular cover, solar energy can be obtained simultaneously. However, since the power generation efficiency of the photovoltaic module will decrease with the increase of temperature, the acceleration channel formed by the semi-circular cover can also cool the photovoltaic module to improve the power generation efficiency of the photovoltaic module, and then the overall power generation amount will increase accordingly, and the overall power generation effect will also be better.

[0030] On the other hand, the embodiment of the present invention further provides a power generation device based on renewable energy. Figure 3 It is the overall framework diagram of a power generation device based on renewable energy according to an embodiment of the present invention. As Figure 3 shown, a power generation device based on renewable energy according to an embodiment of the present invention includes: The lift module 100 is used to establish a lift channel between the upper and lower surfaces of the first airfoil; the lift channel is aligned with the lift direction of the first airfoil; The lift strengthening module 200 is used to increase the lift in the lift channel. The lift strengthening module includes: the lift strengthening module implemented by the method of increasing lift by changing the angle of attack of the first airfoil; the lift strengthening module implemented by setting the lift channel as a fluid acceleration channel with a Venturi effect, where fluid is inhaled from the lower inlet, accelerated through the narrow section, and then released from the upper outlet; the lift strengthening module implemented by arranging a second airfoil below the first airfoil; the lift strengthening module implemented by arranging a support base below the first airfoil, and the support base can guide the oncoming wind to the air inlet of the lift channel; the lift strengthening module implemented by arranging a number of small holes on the rear part of the lower surface and / or both side surfaces of the first airfoil, and under the action of pressure difference, the fluid will be inhaled from the small holes and guided to the lift channel to be accelerated; and the lift strengthening module implemented by arranging a semi-circular cover above the first airfoil, and the semi-circular cover is connected to the first airfoil or the second airfoil to form a fluid acceleration annular channel; the lift strengthening module implemented by at least one of the methods; The wind power generation module 300 is used to arrange one or more fans in the lift channel; then the wind in the lift channel drives the fans, and then drives the wind turbine to convert wind energy into electrical energy.

[0031] According to an embodiment of a power generation device based on renewable energy, the lift strengthening module is implemented by the method of arranging a semi-circular cover above the first airfoil, and the semi-circular cover is connected to the first airfoil or the second airfoil to form a fluid acceleration annular channel; The lift strengthening module is implemented by using any one or more of the following five methods together; the five methods include: The method of increasing lift by changing the angle of attack of the first airfoil; The method of setting the lift channel as a fluid acceleration channel with a Venturi effect, where fluid is inhaled from the lower inlet, accelerated through the narrow section, and then released from the upper outlet; The method of arranging a second airfoil below the first airfoil; The method of arranging a support base below the first airfoil, and the support base can guide the oncoming wind to the air inlet of the lift channel; And the method of arranging a number of small holes on the rear part of the lower surface and / or both side surfaces of the first airfoil, and under the action of pressure difference, the fluid will be inhaled from the small holes and guided to the lift channel to be accelerated.

[0032] One of the technical solutions in the above technical solution has the following advantages or beneficial effects: This application can be installed on a moving object. Compared with traditional wind power equipment, due to the use of an airfoil design in this application, during the movement process, the wind resistance of the oncoming wind can be reduced, and the lift can be converted into kinetic energy, so electricity can be generated during the movement process. Moreover, compared with traditional wind power equipment, the installation height on a moving object is lower, and it has better stability and safety. Furthermore, since the lift channel in this application is consistent with the lift direction of the first airfoil, compared with the prior art where the vertical channel is perpendicular to the bottom of the airfoil, the efficiency is higher.

[0033] Another technical solution in the above technical solution has the following advantages or beneficial effects: By using the Venturi effect, the fluid flowing through the lift channel can be effectively accelerated, further improving the power generation efficiency; a second airfoil is arranged below the first airfoil to increase the upward lift (especially when the first airfoil is installed on the car roof, the car roof can serve as the second airfoil); a base is arranged below the first airfoil to enhance its stability, ensure the angle of attack, avoid excessive angle increasing the resistance, and suck air through the small holes at the tail and both sides of the first airfoil and guide it to the lift channel for acceleration to further increase the lift; a circular cover can also be used to form a closed-loop channel to further accelerate the fluid flow rate in the channel to increase the lift. After several increases in lift, the starting requirement of the wind turbine for wind power can be indirectly reduced; cooperating with placing photovoltaic modules on the cover, wind-solar complementary can be achieved to enhance the power generation effect.

[0034] In the embodiments of the present invention, the streamlined design of the airfoil is utilized to reduce the resistance of the oncoming wind from the front; and according to the characteristic of the pressure difference between the upper and lower surfaces of the airfoil, a lift channel is established between the upper and lower surfaces of the first airfoil to guide the oncoming wind into an upward lift; also referring to the biplane, the lift channel is arranged above the second airfoil to obtain more lift, so as to obtain more kinetic energy required for power generation for the wind power generation equipment arranged in the lift channel (the present invention can be particularly applied to automobiles and can be installed in an embedded manner, that is, an overall design is made during the design of the automobile and the present invention is designed into it and embedded into the automobile during production, for example: embedded in the roof and integrated with the roof design, embedded in the engine hood of the automobile, etc.; it can also be installed and fixed on the roof in a later hanging form, and when the roof of the automobile has the airfoil characteristic and can be used as the second airfoil, no other second airfoil is required); wherein, to obtain greater lift, the lift channel can be arranged at the maximum thickness position, or the pressure center, and the lift action point, etc. of the first airfoil, which are positions of special significance, and the lift channel can also be arranged as a fluid acceleration channel with a Venturi effect, the fluid is sucked in from the lower inlet, accelerated through the narrow section, and then released from the upper outlet; considering that the lift of the airfoil is also related to the angle of attack, in order to keep the first airfoil within the range of the angle of attack with small resistance and large lift, it can be fixed with a base, and at the same time, the base can also guide part of the wind to the inlet of the lift channel and convert it into an upward lift. Moreover, when small holes are arranged on the two side surfaces and / or the lower surface of the first airfoil, due to the pressure difference, the fluid (such as air) will be sucked in from the small holes and guided to the lift channel to be accelerated; in order to further increase the conversion rate of electric energy, also referring to the concept of the annular wing aircraft, a semi-circular cover is added outside the airfoil, which can form an acceleration channel with the first airfoil or the second airfoil. After the oncoming wind is accelerated, it will suck the fluid in the lift channel and then be discharged along with the acceleration channel, indirectly increasing the lift of the lift channel; finally, a photovoltaic module is placed on the upper surface of the semi-circular cover. Through the complementary form of wind and solar energy, the conversion rate of electric energy can be greatly increased. At the same time, this technical solution of wind-solar complementary, in the case of the same usage area, is more space-saving and has higher power generation efficiency compared with single wind power generation or photovoltaic power generation. In addition, the application scenarios of the technical solution of the present invention, in addition to being applicable to installation on moving objects, can also be installed on fixed objects such as rooftops and buildings to realize an energy-saving building with wind-solar complementary, low-carbon and environmental protection!
