[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1 As shown, the present invention provides an island reef solar energy and wind energy complementary power generation device, comprising a box body 1, a spherical solar energy power generation unit 2, a plurality of vertical axis wind energy power generation units 3, a battery 4, a controller 5, a follower unit 6, a second photovoltaic panel 7 and a positioning system module 8, wherein the box body 1 is provided with a spherical solar energy power generation unit 2, the box body 1 is surrounded by a plurality of vertical axis wind energy power generation units 3, and the battery 4 and the controller 5 are fixedly arranged inside the box body 1; the output ends of the spherical solar energy power generation unit 2 and the vertical axis wind energy power generation unit 3 are both electrically connected to the battery 4, and the spherical solar energy power generation unit 2 and the battery 4 are also electrically connected to the controller 5;

[0034] The spherical solar power generation unit (2) follows the sun's trajectory and gathers incident sunlight to generate photovoltaic power, and stores the generated electrical energy in a storage battery (4);

[0035] The vertical axis wind power generation unit 3 is driven by wind energy to generate electricity and stores the generated electric energy in the storage battery 4;

[0036] The storage battery 4 stores the electric energy generated by the spherical solar power generation unit 2 and the vertical axis wind power generation unit 3;

[0037] The controller 5 enables the storage battery 4 to output electric energy. When the storage battery 4 is fully charged, if the spherical solar power generation unit 2 or the vertical axis wind power generation unit 3 continues to charge, the controller 5 can guide the excess electric energy into the unloader, merge it into the power grid or use it in the electric equipment, so as to prevent the storage battery 4 from being overcharged. Through the complementary characteristics of solar power generation and wind power generation, the spherical solar power generation unit 2 and the vertical axis wind power generation unit 3 are set up at the same time on the island or seaside area. When the sunlight is strong during the day, solar power generation is mainly used, and wind power generation is mainly used at night, so that electric energy can be continuously obtained at different time periods.

[0038] like Figure 2 Combination Figure 4As shown, the spherical solar power generation unit 2 includes a base 21, a first motor 22, a bracket 23, a spherical condensing lens 24 and a first photovoltaic panel 25. The base 21 is fixedly arranged on the box 1, the first motor 22 is arranged in the box 1, and the output shaft of the first motor 22 is fixedly connected to the base 21; the bracket 23 is fixedly arranged on the base 21, the condensing lens 24 is fixedly arranged on the bracket 23, and the first photovoltaic panel 25 is arranged on the output light path of the condensing lens 24; the first motor 22 is electrically connected to the controller 5, and the first motor 22 drives the bracket 23, the condensing lens 24 and the first photovoltaic panel 25 to rotate relative to the box 1. As can be seen from the figure, the first motor 22 can drive the base 21, the bracket 23, the condensing lens 24 and the first photovoltaic panel 25 to rotate clockwise or counterclockwise relative to the longitudinal central axis of the box 1, so as to realize the single-axis tracking of the bracket 23 as a whole and the first photovoltaic panel 25 relative to the sun's trajectory. However, in the spherical solar power generation unit 2 of this structure, the sunlight collected by the focusing lens 24 does not always fall completely on the first photovoltaic panel 25, and some of the collected sunlight is wasted. The spherical solar power generation unit 2 is preferably arranged on the top of the box 1 to fully receive sunlight.

[0039] In order to further improve the first photovoltaic panel 25 to follow the sun's trajectory and improve the power generation effect, a following unit 6 is also provided in the spherical solar power generation unit 2, and the first photovoltaic panel 25 is fixedly connected to the following unit 6. The following unit 6 can drive the first photovoltaic panel 25 to rotate relative to the center of the focusing lens 24, so that the sunlight gathered by the focusing lens 24 is completely projected on the first photovoltaic panel 25, further improving the utilization rate of sunlight.

[0040] like Figure 4 As shown, a specific structure of the following unit 6 is provided. The following unit 6 includes an arc track 61, a box body 62, a running wheel 63 and a second motor 64. The arc track 61 is fixedly arranged on the bracket 23, and the arc track 61 is concentrically arranged with the focusing lens 24. The box body 62 is arranged on the side of the arc track 61 close to the focusing lens 24. The box body 62 is hingedly connected with the running wheel 63. The running wheel 63 is embedded in the arc track 61 and is rollingly connected with the arc track 61; the second motor 64 is fixedly arranged in the box body 62, and the output shaft of the second motor 64 passes through the box body 62 and extends in the direction of the arc track 61. A driven gear disc is arranged on the wheel axle of the running wheel 63, and a driving gear disc is arranged on the output shaft of the second motor 64, and the driving gear disc is meshed with the driven gear disc; the first photovoltaic panel 25 is fixedly arranged at one end of the box body 62 close to the focusing lens 24; the second motor 64 is electrically connected to the controller 5.

[0041] The focusing lens 24 shown in the figure is fixed on the bracket 23, and the two ends of the arc track 61 are respectively fixed to the fixed bracket 23. The arc track 61 is arranged to semi-surround the focusing lens 24. The box body 62 and the first photovoltaic panel 25 can move in a large range of 180° along the arc track 61 relative to the center of the focusing lens 24, that is, rotate relative to the central axis of the focusing lens 24, so as to further realize the tracking function of the incident solar light. The first photovoltaic panel 25 on the arc track 61 is perpendicular to the light emitting direction of the focusing lens 24. The energy density of the focused sunlight is higher. Compared with photovoltaic panels of the same area, the first photovoltaic panel 25 has a higher power generation efficiency.

[0042] In the present invention, the second motor 64 drives the travel wheel 63 by adopting a gear drive structure, or by adopting a pulley, chain or other transmission methods.

[0043] The condenser lens 24 used in the present invention is a spherical lens. The sunlight irradiated on the surface of the condenser lens 24 passes through the center of the sphere and converges on the light-emitting side thereof. The spherical lens structure is completely symmetrical, and its installation on the fixing bracket 23 is more convenient.

[0044] like Figure 1 , Figure 2 Combination Figure 5 and Figure 6 As shown, the vertical axis wind power generation unit 3 includes a generator 31, a transmission shaft 32, a rotating frame 33 and a plurality of blades 34. The generator 31 is fixedly arranged relative to the housing 1. A vertical transmission shaft 32 is arranged on the top of the generator 31, and one end of the transmission shaft 32 is fixedly connected to the generator 31. A rotating frame 33 is fixedly arranged on the top of the transmission shaft 32, and a plurality of blades 34 are arranged at the edge of the rotating frame 33. The blades 34 are fixedly connected to the rotating frame 33, and the blades 34 extend outward along the length direction of the transmission shaft 32. The edges of the blades 34 are located on the circumference of the same virtual cylindrical surface. The blades 34 and the rotating frame 33 drive the transmission shaft 32 to rotate together, so that the generator 31 generates an induced current through electromagnetic induction. The vertical axis structure adopted by the vertical axis wind power generation unit 3 allows each blade 34 to be driven by wind alone. The blades 34 can extend outward along the axial direction of the transmission shaft 32, that is, parallel to the transmission shaft 32; or they can be at a certain inclination angle to the axial direction of the transmission shaft 32, so that it is easier to drive the rotating frame 33 and the transmission shaft 32 to rotate when exposed to wind. The electrical part is arranged at the bottom of the vertical axis wind power generation unit 3, which is convenient for repair and maintenance. Each vertical axis wind power generation unit 3 in the figure has three blades 34, which can actually be arranged as 4, 6 or more, not limited by the figure.

[0045] As a further improvement of the present invention, a baffle 35 is also provided on each blade 34, and the two ends of the baffle 35 are fixedly connected to the side of the blade 34, and the middle part of the baffle 35 protrudes in the direction away from the surface of the blade 34. Since the protruding direction of the baffle 35 is different from the windward surface of the blade 34, the windward area of ​​the blade 34 can be increased, so that the blade 34, the rotating frame 33 and the transmission shaft 32 can be involved in the rotation and power generation at a lower wind speed, thereby realizing the start-up and power generation at a low wind speed. The vertical axis wind power generation units 3 shown in the figure of the present invention are two, symmetrically arranged on the side of the box body 1. In actual use, more vertical axis wind power generation units 3 can be arranged without affecting the lighting of the spherical solar power generation unit 2. For example, 4, 8, etc. vertical axis wind power generation units 3 are arranged around the spherical solar power generation unit 2.

[0046] In order to facilitate the maintenance of the vertical axis wind power generation unit 3 and provide protection for it under severe weather conditions, the vertical axis wind power generation unit 3 also includes a linear lifting mechanism 36 and a cylinder 37 with a position locking function. The linear lifting mechanism 36 is fixedly arranged at the bottom of the generator 31, and the linear lifting mechanism 36 drives the generator 31 and the transmission shaft 32 to move along the axial direction of the transmission shaft 32; the cylinder 37 is arranged around the linear lifting mechanism 36, and the size of the cylinder 37 is larger than the diameter of the virtual cylindrical surface where the blades 34 are located. When severe weather such as typhoons come, the linear lifting mechanism 36 will be lowered, and the vertical axis wind power generation unit 3 will be completely hidden in the cylinder 37 to prevent strong winds or foreign objects from causing damage to the vertical axis wind power generation unit 3. Correspondingly, in order to measure the wind speed, an anemometer can be configured on the vertical axis wind power generation unit 3 to measure the wind speed in real time. If the wind speed exceeds 32m / s, it is considered that there is a typhoon, and the linear lifting mechanism 36 will lower the vertical axis wind power generation unit 3. The linear lifting mechanism 36 can be implemented by a hydraulic mechanism, a cylinder mechanism or a screw mechanism.

[0047] In addition, in order to make full use of the limited space of the equipment, a second photovoltaic panel 7 is fixedly arranged on the outer surface of the box body 1, the spherical solar power generation unit 2 and the cylinder 37, and the second photovoltaic panel 7 is electrically connected to the battery 4. The second photovoltaic panel 7 is fixedly arranged and can be used as a further supplement to the spherical solar power generation unit 2, making full use of the limited space of the equipment and converting more electric energy.

[0048] In order to better achieve the tracking effect of the sun's trajectory, the present invention also includes a positioning system module 8, which is electrically connected to the controller 5. The positioning system module 8 sends the current longitude and latitude information to the controller 5, and the controller 5 converts the longitude and latitude information into the solar azimuth after receiving the longitude and latitude information, and makes the spherical solar power generation unit 2 face the direction of sunlight. The positioning system module 8 can use a GPS module or a Beidou module to provide the current time and longitude and latitude information at a regular interval. The controller 5 converts the current position of the sun's trajectory according to the current time and longitude and latitude information, and controls the first motor 22 and the second motor 64 to act respectively, driving the first photovoltaic panel 25 to face the direction of the sun.

[0049] The current position of the sun's trajectory can be determined by the longitude and latitude of the observation point and the marked time. The positioning system module 8 can regularly obtain the local longitude and latitude information and the current time. The controller 5 converts the longitude and latitude information into the solar azimuth as follows:

[0050] The orbit of the Earth around the Sun is an ellipse, with the Sun located at one of the foci of the ellipse. r is used to represent the distance between the Sun and the Earth, and r0 is used to represent the average distance between the Sun and the Earth. r0 = 1.496 × 10 8 km, distance between the sun and the earth E R It can be expressed by the following formula:

[0051] E R =1.000426+0.032359sinθ+0.000086sin2θ-0.008349cosθ+0.000115cos2θ;

[0052] The θ in the above formula is the day angle, that is, θ = 2πt / 365.2422, where t = N-N0, N is the cumulative day, that is, the serial number of the date in a year, the cumulative day of January 1 is 1, the cumulative day of December 31 is 365, and the cumulative day of December 31 in a leap year is 366. N0 = 79.6764 + 0.422 × (year-1985)-INT[(year-1985) / 4], that is, the day angle θ is related to the year and date.

[0053] The solar declination angle δ can be expressed by the following formula:

[0054] δ=0.3732+23.2567sinθ+0.1149sin2θ-0.1712sin3θ-0.758cosθ+0.3656cos2θ+0.0201cos3θ;

[0055] The speed of the sun on the ecliptic is not constant, and the length of the true solar day varies. The imaginary sun moves at a constant speed. The time it takes for this imaginary sun to pass twice in the sky is called a mean solar day. 1 / 24 of the mean solar day is the mean solar time. One true solar day is different from one mean solar day. 1 / 24 of the true solar day is the true solar time. The time difference between the true solar time and the mean solar time is expressed by E. t express:

[0056] S0=S+E t ; S0 is true solar time, S is mean solar time. Time difference E t It can be expressed by the following formula:

[0057] E t =0.0028-1.9857sinθ+9.9059sin2θ-7.0924cosθ-0.6882cos2θ;

[0058] The sun's altitude h0 can be calculated using the following formula:

[0059] Where δ is the solar declination angle, The geographical latitude provided by the positioning system module 8; τ is the local solar hour angle;

[0060] τ=(S0+F0 / 60-12)×15°; where S0 is true solar time and F0 is true solar minute, which is 1 / 60 of true solar time.

[0061] To calculate the true solar time S0, it is necessary to convert the Beijing time represented by the mean solar time S into the local time S d :

[0062] S d =S+{F-[120°-(JD+JF / 60)]×4} / 60;

[0063] Where S is the current hour of Beijing time expressed by mean solar time, and F is the current minute of Beijing time; JD is the local longitude, and JF is the local longitude and minute; 120° is the standard accuracy of Beijing time, multiplying by 4 is to convert the angle into time, that is, one degree is equivalent to 4 minutes; dividing by 60 is to convert minutes into hours;

[0064] Then the local time S d Correct the time difference, S0 = S d +E t / 60; that is, the true solar time after the time difference correction, based on this S0, the local solar hour angle τ and solar altitude h0 are calculated.

[0065] After obtaining the local solar altitude h0, calculate the solar azimuth A:

[0066]

[0067] The solar azimuth angle A has two values, when cosA≤0, 90°≤A≤180°; when cosA≥0, 0≤A≤90°, and the latter A value is 360°-A. The corresponding position of the first photovoltaic panel 25 can be adjusted by the solar azimuth angle and the solar altitude so that it faces the direction of the sun's radiation. The present invention uses the solar trajectory based on time and longitude and latitude to realize the tracking function of the first photovoltaic panel 25. Late at night, such as midnight, the following unit 6 drives the first photovoltaic panel 25 back to the initial position, such as the horizontal position, and waits for the sun to rise the next day before tracking and generating electricity again.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
