Description

[Technical field]

[0001] The present invention relates to the field of energy, and in particular to an energy conversion device. The present invention also relates to an autonomous energy device, and the present invention also relates to an energy use control method of the autonomous energy device. [Background Technology]

[0002] There are many energy sources in nature, such as solar energy, wind energy, and water energy. Taking advantage of the geographical location of different regions, photovoltaic panels are used to receive sunlight, wind turbines are used to rotate, water wheels are used to rotate, and other mechanical equipment is used to convert the above natural energy into electrical energy. The converted electrical energy in the region is transmitted to each household and outdoor functional equipment through the power grid. At present, the power supply of various functional equipment in the home or outdoors is mainly powered by the power grid. Some household electrical appliances, such as water heaters and outdoor street lights, are powered by photovoltaic panels or fans, but the conversion efficiency is limited and they still rely on the power supply of the municipal grid to maintain their use.

[0003] In addition, the photovoltaic panels of existing solar water heaters are generally placed on the roof, which limits their installation. The photovoltaic panels on street lamps are generally made smaller to take into account the influence of wind, and their energy conversion is limited. They rely on power supply from the grid to maintain lighting. Moreover, the photovoltaic panels of such street lamps are mainly fixed on the brackets of the poles, which are easily tilted by the wind. Even if they are firmly fixed, the light absorption efficiency is low due to the fixed direction. Even if there are steering tracking devices, their cost is high.

[0004] Therefore, there is a need for an energy conversion device that has low manufacturing cost, stable and reliable use, and can improve energy conversion efficiency.

[0005] The patent application with publication number CN114128134A, entitled "Pillar with at least one photovoltaic element and use of photovoltaic element on a pillar", discloses that the photovoltaic element is arranged on the surface of the pillar in a form-fitting manner, especially bonded to the surface of the pillar, and the pillar can be used to generate energy efficiently, and in particular the effectiveness of the wind power facility is not affected. The solar cell is advantageously placed on the pillar in a form-fitting manner and is therefore not susceptible to damage by wind or other weather effects. Compared with the conventional protruding solar panels, the noise generated by the wind is advantageously reduced. The existing area of ​​the pillar is used to arrange the photovoltaic element, and therefore no additional area is required. The photovoltaic element is advantageously adapted to the shape of the pillar, thereby achieving greater stability with respect to strong winds and damage caused thereby. The flexible photovoltaic element is advantageously particularly light, so that a larger number of photovoltaic elements can be attached to the pillar without exceeding a certain weight. However, the photovoltaic element, which is limited to a flexible photovoltaic element, has a high manufacturing cost, and the sunlight can only illuminate the photovoltaic panel from the front, and only one side absorbs light, and the light absorption efficiency is low. In addition, when installing photovoltaic panels, it is necessary to set an inclination angle, that is, the angle at which the photovoltaic panels face the sun to receive sunlight. Therefore, the photovoltaic panels can have the best reception efficiency within 10 to 14 hours from sunrise to sunset. When installing outdoors, the outdoor environment is more complicated, and there may be buildings or trees around to block the sunlight. Some photovoltaic panels will not receive sunlight, which will cause waste of photovoltaic panels. Therefore, it is necessary to solve the above technical problems.

[0006] In addition, in some remote areas, there is currently no power grid supply, and energy equipment that can sustainably maintain power supply is particularly needed. Therefore, it is necessary to develop an autonomous energy device that can adapt to different environments, regions, and climates at home and abroad, and flexibly and comprehensively utilize natural energy such as solar energy, wind energy, and water energy, and can achieve high-efficiency energy conversion, generator power generation, power storage, and use.

Each light guide component 3 is provided with a light-incoming surface 300 exposed from the left and right sides of the photovoltaic unit 21, for receiving light irradiated from the gap 20 between the left and right photovoltaic units 21.

[0065] Preferably, the photovoltaic unit 21 is arranged to be tilted outward and upward to facilitate receiving light.

[0067] As one of the embodiments of the photovoltaic unit of the present invention, the photovoltaic unit 21 can be attached and fixed on the surface of the main pole 1. Fig.16 shown.

[0068] The photovoltaic unit is packaged on the surface of the main pole 1. The main pole can adopt various structures, and has various implementations listed below:

[0069] Embodiment 1: The main rod 1 is an integrated structure, such as Fig.16 As shown, the photovoltaic unit 21 is packaged on the outer wall of the main pole 1.

It is easy to assemble and stable and reliable to use.

[0071] like Figures 18 to 20 As shown, the main rod 1 can also be designed as a polygonal structure such as a triangle, a quadrilateral, a pentagon, etc.

[0072] As another embodiment of fixing the photovoltaic unit: it can also be fixed on the main pole by sleeve connection, such as Figures 1 to 6 As shown in Figure 15, specifically, the upper and lower ends of the plurality of photovoltaic units 21 in the same layer are provided with connectors 22 for connecting and fixing the plurality of photovoltaic units 21 into a photovoltaic module 2, and the middle of the photovoltaic module 2 is provided with a through hole 23 that can be inserted into the main pole 1, and the main pole 1 is provided with a plurality of groups of photovoltaic modules 2 on the upper and lower ends.

[0074] In the present invention, a lighting device 4 can be additionally provided on the energy conversion device. The lighting device can be used for nighttime lighting and can also enable the photovoltaic unit to continue to work and convert electrical energy at night. A lighting device 4 capable of illuminating the photovoltaic unit 21 of the lower layer is installed below the photovoltaic unit 21 of the upper layer. When the lighting device is set, the upper end of the photovoltaic unit 21 of the lower layer is located on the inner side of the lower end of the photovoltaic unit 21 of the upper layer. Because the lighting device is installed at different heights of the main pole, lighting devices with different powers and different illumination angles can be set according to the installation position. Furthermore, the lighting device 4 can be installed at the bottom of the photovoltaic unit 21, such as Fig.12 It is also possible to provide a mounting seat 13 for mounting electronic equipment on the main rod 1, and the lighting device 4 is mounted on the mounting seat 13, such as Figure 6 and 14 As shown.

The main pole wind turbine can be a vertical axis wind turbine. A hydroelectric generator can also be set on the main pole to flexibly use multiple energy sources such as light, wind and water for electrical energy conversion.

[0076] As an embodiment of the energy conversion device of the present invention using hydroelectric power generation, a hydroelectric generator is provided on the main pole 1, and a water receiving funnel 51 and a water receiving pipe for collecting and directing the water flow collected by the water receiving funnel 51 to the hydroelectric generator are provided at the bottom of the photovoltaic unit 21 located above the hydroelectric generator. Fig.15 Of course, the water funnel can also be installed on the side of the main rod. Fig.16 As shown. The water receiving funnel can be made of light-transmitting or non-light-transmitting materials. When a lighting device is installed below the photovoltaic unit, such as when the lighting device is arranged at the bottom of the photovoltaic unit and is covered by the water receiving funnel, the water receiving funnel is made of light-transmitting materials. By arranging a water receiving funnel at the bottom of the photovoltaic unit, the photovoltaic unit can collect water while converting light energy. The structure is simple and the spatial structure of the main pole is fully utilized. The water flows to the hydroelectric generator through the water receiving pipe. The main pole has a high height. The water flow collected from top to bottom has a high gravitational potential energy, which can realize hydroelectric power generation. Therefore, the energy conversion device can generate both photovoltaic and hydroelectric power, and the energy conversion rate is high.

[0077] In order to adapt to high temperature environment, the energy conversion device of the present invention can also be provided with a heat dissipation component 6 for heat dissipation at the bottom of the photovoltaic unit 21, such as Fig.13 As shown. The heat dissipation component cools and dissipates the heat for the photovoltaic unit to maintain the high conversion efficiency of the photovoltaic unit and prevent the risks caused by continuous high temperature. The heat dissipation component can be set as an exhaust fan, etc.

[0078] In order to prevent lightning strikes from affecting the energy conversion device, a lightning protection device 400 is installed on the upper end of the main pole.

[0079] The present invention also shows an autonomous energy device, which has an energy conversion device as described above, and an energy control cabinet 7 is provided at the bottom of the main pole 1. A battery pack 8 and a controller 9 for energy storage are provided in the energy control cabinet 7, and the battery pack 8 and the energy conversion device are electrically connected to the controller 9. The autonomous energy device of the present invention has a high energy conversion efficiency of the photovoltaic unit. In addition, on a main pole, photovoltaic units, wind turbines and / or hydroelectric generators can be flexibly combined to make full use of various energy sources in nature, which are then converted into electrical energy and stored in the battery pack. A large amount of electrical energy can be converted and stored, and when supplying power to other electrical equipment, it can maintain operation for a long time.

[0080] Furthermore, a magnetic energy generator 10 is installed in the energy control cabinet 7. The magnetic energy generator can be started to work when the energy conversion device fails seriously or the power storage of the battery pack is too low, and is used for backup power generation.

[0081] The energy control cabinet 7 is provided with an inspection door.

[0082] A method for controlling energy use of an autonomous energy device as described above, wherein the battery pack 8 comprises a first battery 81 and a second battery 82 which are electrically connected, and the autonomous energy device comprises a lighting device 4,

[0083] When the controller detects that the electric energy stored in the first storage battery 81 is lower than the preset minimum electric energy value of the first storage battery 81, the controller controls the second storage battery 82 to replenish the electric energy stored therein into the first storage battery 81, and the controller controls the lighting device 4 to work;

[0084] When the controller detects that the electric energy stored in the second storage battery 82 is lower than the preset minimum electric energy value of the second storage battery 82, the controller controls the magnetic energy generator to start working;

[0085] When the total electric energy stored in the second storage battery 82 reaches the preset maximum electric energy value of the second storage battery 82, the magnetic energy generator stops working.

[0086] The electric energy converted by the autonomous energy device of the present invention can be processed to supply electricity to electrical equipment, while natural light energy, water energy, wind energy, etc. are limited by time and other objective factors. For example, when there is insufficient light on a cloudy day, or at night, or when there is no wind or rain, the autonomous energy device converts less electric energy, or is unable to perform energy conversion. The electrical equipment only relies on the electric energy stored in the battery, and the electric energy is quickly consumed. Therefore, it is necessary to set up power generation equipment such as a magnetic energy generator as supplementary power generation, and the lighting device illuminates at night. The photovoltaic unit can also continue to work at night to convert electric energy to supplement the battery pack. Through the above-mentioned approach, the power supply of the autonomous energy device can be maintained for a certain period of time.
