Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a wind power and photovoltaic complementary power generation system. Background Art

[0002] Energy shortage and climate change are severe challenges faced by all mankind. Vigorously developing renewable energy represented by photovoltaics and wind power is an effective means to achieve energy transformation, solve energy shortages, alleviate environmental pollution and other problems, and plays an important role in the process of sustainable development of my country's energy and economy.

[0003] Currently, the existing Chinese patent publication number CN114039528A discloses an automatic directional photovoltaic-wind power complementary power generation device, the existing Chinese patent publication number CN111441907A discloses an automatic directional photovoltaic-wind power complementary power generation device, and the existing Chinese patent publication number CN214626846U discloses an automatic directional photovoltaic-wind power complementary power generation device. The above-mentioned devices only achieve the function of complementary power generation by fixing the bracket supporting the solar panel at a certain position on the pillar body of the wind power generation device, and then connecting the solar panel and wind power to the grid. However, the device has some shortcomings: 1. The position of the solar panels is a fixed structure. Due to the different horizontal and vertical positions of the sun at different times, the utilization rate of the solar panels is low; 2. When the device encounters strong winds, especially when the angle between the airflow direction and the solar panel surface is large, such as an angle of more than 70 degrees, the columns are subjected to large radial forces, which increases the column load. Summary of the Invention

[0004] The purpose of the present invention is to provide a wind power and photovoltaic complementary power generation system in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A wind power and photovoltaic complementary power generation system, comprising a wind power generation system and a photovoltaic power generation system, both of which are connected to a power grid; the wind power generation system comprises a support column, a wind turbine body is provided on the top of the support column, and wind turbine blades are provided at the head end of the wind turbine body; the photovoltaic power generation system comprises a mounting tube and a photovoltaic panel, the mounting tube being coaxially rotatably connected to the support column body at a position below the wind turbine blades, the photovoltaic panel being rotatably connected to the outside of the mounting tube, and the rotation center axis of the photovoltaic panel being perpendicular to the rotation center of the mounting tube;

[0007] The photovoltaic power generation system also includes an adjustment system that can drive the installation cylinder and the photovoltaic panel to rotate, so as to increase the angle between the photovoltaic panel surface and the sunlight.

[0008] Preferably, the adjustment system includes a rotating shaft, a connecting column, and a connecting rod. The rotating shaft is arranged parallel to the support column and is rotatably connected to the support column, and the end of the rotating shaft is engaged with the mounting cylinder through a gear. The connecting column is spaced parallel to the support column, and one end is hinged to the photovoltaic panel. The rotating shaft body is connected to a connecting rod that can push the connecting column to move away from or closer to the support column when the rotating shaft rotates, so that the vertical tilt angle of the photovoltaic panel is first reduced and then increased during the day.

[0009] The adjustment system further comprises a driving device for driving the rotating shaft to rotate.

[0010] Preferably, the connecting rod is a horizontally arranged T-shaped rod, the belly of the connecting rod is movably connected to a movable block along its length direction, and the movable block is correspondingly connected to the shaft body of the rotating shaft, and the end of the connecting rod away from its belly is movably connected to the connecting column along the length direction of the connecting column.

[0011] Preferably, the regulating system includes a control system and a pressure detection system for detecting the pressure of the photovoltaic panel on the installation cylinder, the pressure detection system is connected to the control system by signal, and the control system is connected to the driving device by signal;

[0012] The speed detection system for detecting the speed of the wind turbine body shaft in the wind power generation system is connected to the control system signal in the regulation system.

[0013] Preferably, horizontal pillars are provided on two opposite sides of the mounting tube, and the two horizontal pillars are coaxially arranged. Each horizontal pillar body is rotatably connected to one of the photovoltaic panels, and a connecting seat is commonly connected between the two photovoltaic panels, and the connecting seat is driven and connected to the adjustment system.

[0014] Preferably, two mounting tubes are spaced apart along the length direction of the support column, and the photovoltaic panels on the two mounting tubes are respectively hinged to the two ends of the connecting column, and the rotation centers at both ends of the connecting column and the rotation centers of the upper and lower photovoltaic panels form a parallelogram structure.

[0015] The beneficial effects are:

[0016] 1. Due to the setting of the adjustment system, the driving device can drive the rotating shaft to rotate, the rotating shaft drives the installation cylinder to rotate, and the installation cylinder drives the photovoltaic panel to move along the circumference of the support column, so that the photovoltaic panel can face the sunlight in the horizontal direction; at the same time, the rotation of the rotating shaft drives the connecting rod to move away from or close to the support column. Using the principle of parallelogram, the up and down tilt angle of the photovoltaic panel also changes at this time, so that the photovoltaic panel faces the sunlight as much as possible in the vertical direction. This solves the technical problem of the existing technology that the position of the solar panel is fixed and the posture of the solar panel cannot be adjusted according to the position of the sun, and achieves the effect of improving the utilization rate of the photovoltaic panel of sunlight;

[0017] 2. Due to the setting of the pressure detection system and the speed detection system, in windy weather, the angle between the photovoltaic panel surface and the airflow direction can be reduced through the signal feedback of the pressure detection system and the speed detection system, and the adjustment system can adjust the position and posture of the photovoltaic panel. Even the photovoltaic panel can be parallel to the airflow direction, which not only reduces the force on the photovoltaic panel, but also reduces the radial force on the support column.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0030] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0031] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0033] In the present invention, unless otherwise expressly specified or limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being above, above, and above the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0034] Example 1, as Figure 1-5 As shown, a wind power and photovoltaic complementary power generation system includes a wind power generation system 1 and a photovoltaic power generation system 2, and the wind power generation system 1 and the photovoltaic power generation system 2 are both connected to the power grid; specifically, the wind power generation system 1 and the photovoltaic power generation system 2 can be connected to the power grid through a double-split transformer; the wind power generation system 1 includes a support column 11, a wind turbine body 12 is provided on the top of the support column 11, and a wind turbine blade 13 is provided at the head end of the wind turbine body 12; the photovoltaic power generation system 2 includes a mounting tube 21 and a photovoltaic panel 22, the mounting tube 21 is coaxially connected to the support column 11 at a position below the wind turbine blade 13, and the photovoltaic panel 22 is connected to the outside of the mounting tube 21, and the rotation center axis of the photovoltaic panel 22 is perpendicular to the rotation center of the mounting tube 21;

[0035] The photovoltaic power generation system 2 further includes an adjustment system 3 capable of driving the installation cylinder 21 and the photovoltaic panel 22 to rotate, so as to increase the angle between the surface of the photovoltaic panel 22 and the sunlight.

[0036] In some embodiments, as Figure 1-3 As shown, horizontal pillars 211 are provided on both opposite sides of the mounting tube 21, and the two horizontal pillars 211 are coaxially arranged. Each horizontal pillar 211 is rotatably connected to a photovoltaic panel 22. A connecting seat 23 is commonly connected between the two photovoltaic panels 22, and the connecting seat 23 is driven and connected to the adjustment system 3. In this way, the two photovoltaic panels 22 are symmetrically arranged on both sides of the support column 11, so that the two photovoltaic panels 22 exert the same force on the support column 11, and the support column 11 will not be subjected to a large deflection force.

[0037] In some embodiments, as Figure 2-5As shown, the adjustment system 3 includes a rotating shaft 31, a connecting column 32, and a connecting rod 33. The rotating shaft 31 is arranged parallel to the support column 11 and is rotatably connected to the support column 11, and the end of the rotating shaft 31 is engaged with the mounting cylinder 21 through a gear. Specifically, a bearing seat is provided on the side of the support column 11 corresponding to the rotating shaft 31, and the rotating shaft 31 is connected to the bearing seat through a bearing; the connecting column 32 is spaced parallel to the support column 11, and one end is hinged to the photovoltaic panel 22; the rotating shaft 31 is connected to the shaft body of the rotating shaft 31, which can push the connecting column 32 to move away from or close to the support column 11 when it rotates, so that the up and down tilt angle of the photovoltaic panel 22 is first reduced and then increased during the day;

[0038] The adjustment system 3 further includes a driving device 34 for driving the rotating shaft 31 to rotate;

[0039] Furthermore, the driving device 34 is a motor, and the motor output shaft is provided with a coaxial worm gear structure, which drives the rotating shaft 31 to rotate.

[0040] When in use, the driving device 34 can be used to drive the rotating shaft 31 to rotate, and the rotating shaft 31 can drive the installation tube 21 to rotate, and the installation tube 21 can drive the photovoltaic panel 22 to move in a circle along the support column 11, so that the photovoltaic panel 22 can face the sunlight in the horizontal direction; at the same time, the rotation of the rotating shaft 31 drives the connecting rod 33 to move away from or close to the support column 11. Using the principle of parallelogram, the up and down inclination angles of the photovoltaic panel 22 also change at this time, so that the photovoltaic panel 22 can face the sunlight as much as possible in the vertical direction, which solves the technical problem in the prior art that the position of the solar panel is fixed and the posture of the solar panel cannot be adjusted according to the position of the sun, thereby achieving the effect of improving the utilization rate of the photovoltaic panel 22 for sunlight.

[0041] Furthermore, the connecting rod 33 is a horizontally arranged T-shaped rod. The belly of the connecting rod 33 is movably connected to a movable block 35 along its length, and the movable block 35 is correspondingly connected to the axial body of the rotating shaft 31. The end of the connecting rod 33 away from the belly is movably connected to the connecting column 32 along the length direction of the connecting column 32. Specifically, the connecting rod 33 can only move along the length direction of the connecting column 32, and the two cannot rotate relative to each other.

[0042] Specifically, the distance between the movable block 35 and the rotating shaft 31 is designed according to the local sunlight inclination angle in the morning, noon and evening. Furthermore, the distance between the movable block 35 and the rotating shaft 31 can also be designed according to the local sunlight inclination angle at all times during the day.

[0043] Furthermore, the connecting rod 33 may be provided with a length-adjustable rod. Specifically, for example, in the northern hemisphere, the length of the connecting rod 33 in the summer season is shorter than the length in the winter season.

[0044] Specifically, the body of the rotating shaft 31 is provided with a horizontal connecting piece, and the movable block 35 is fixed to the body of the rotating shaft 31 through the connecting piece. For details, reference may be made to the working principle of a cam.

[0045] Furthermore, a mounting structure for mounting the driving device 34 is provided on the support column 11 , and the connecting rod 33 is slidably connected to the mounting structure along its axial direction.

[0046] During use, the rotation of the rotating shaft 31 drives the installation cylinder 21 to rotate, and the installation cylinder 21 drives the photovoltaic panel 22 to move in a circle along the support column 11, so that the photovoltaic panel 22 can face the sunlight in a horizontal direction; at the same time, the rotation of the rotating shaft 31 drives the movable block 35 to move along its circle, and the movable block 35 pulls or pushes the connecting rod 33, so that the connecting rod 33 moves away from or close to the support column 11. Using the principle of parallelogram, the up and down inclination angles of the photovoltaic panel 22 also change at this time, so that the photovoltaic panel 22 can face the sunlight as much as possible in the vertical direction, which solves the technical problem in the prior art that the position of the solar panel is fixed and the posture of the solar panel cannot be adjusted according to the position of the sun, thereby achieving the effect of improving the utilization rate of the photovoltaic panel 22 for sunlight.

[0047] Specifically, in my country, the sun rises from the east in the morning and is located in the south at noon, and during the morning period, the inclination angle of the sunlight gradually increases; the sun is located in the west in the evening, and during the afternoon period, the inclination angle of the sunlight gradually decreases; in this embodiment, when the sun rises in the morning, the surface of the photovoltaic panel 22 is facing east in the horizontal direction, and the movable block 35 is located at one end of the belly of the connecting rod 33 at this time, that is, at this time, the photovoltaic panel 22 has the largest vertical inclination angle, and then according to the above working principle, the surface of the photovoltaic panel 22 gradually rotates toward the south in the horizontal direction, and the movable block 35 moves toward the central position of the belly of the connecting rod 33 at this time, thereby making the photovoltaic panel 22 in the vertical direction gradually decrease. Similarly, in the afternoon, the surface of the photovoltaic panel 22 gradually moves from south to west in the horizontal direction, and the vertical inclination angle of the photovoltaic panel 22 surface gradually increases. Therefore, the setting of the adjustment system 3 can make the surface of the photovoltaic panel 22 as perpendicular to the sunlight as possible throughout the daytime.

[0048] Example 2, based on Example 1, Figure 2-5 As shown, two mounting tubes 21 are spaced apart along the length direction of the support column 11, and the photovoltaic panels 22 on the two mounting tubes 21 are respectively hinged to the two ends of the connecting column 32, and the rotation centers at both ends of the connecting column 32 and the rotation centers of the upper and lower photovoltaic panels 22 form a parallelogram structure.

[0049] When in use, the driving device 34 can be used to drive the rotating shaft 31 to rotate, the rotating shaft 31 drives the mounting tube 21 to rotate, and the mounting tube 21 drives the photovoltaic panel 22 to move in a circle along the support column 11, so that the photovoltaic panel 22 can face the sunlight in the horizontal direction; at the same time, the rotation of the rotating shaft 31 drives the connecting rod 33 to move in the direction away from or close to the support column 11, and the connecting rod 33 drives the connecting column 32 to move in the direction away from or close to the support column 11. Using the principle of parallelogram, the support column 11 moves up and down accordingly. At this time, the up and down inclination angles of the photovoltaic panel 22 also change, so that the photovoltaic panel 22 can face the sunlight as much as possible in the vertical direction, which solves the technical problem in the prior art that the position of the solar panel is fixed and the posture of the solar panel cannot be adjusted according to the position of the sun, thereby achieving the effect of improving the utilization rate of the photovoltaic panel 22 for sunlight.

[0050] In the third embodiment, based on the first embodiment, the regulating system 3 includes a control system and a pressure detection system for detecting the pressure of the photovoltaic panel 22 on the mounting cylinder 21. The pressure detection system is connected to the control system by signal, and the control system is connected to the driving device 34 by signal.

[0051] The speed detection system for detecting the speed of the shaft of the wind turbine body 12 in the wind power generation system 1 is connected to the control system signal in the regulation system 3 .

[0052] Specifically, the pressure detection system is annularly distributed and sleeved on the column body of the horizontal pillar 211, and the detection direction of the pressure detection system is set along the radial direction of the horizontal pillar 211.

[0053] Specifically, the priority of the speed detection system to the control system in the regulation system 3 is greater than the priority of the preset operation of the regulation system 3 itself; for example, when the speed detection system detects that the speed of the shaft of the wind turbine body 12 is relatively high, it means that the surrounding environment is in a strong wind environment. At this time, the speed detection system transmits the signal to the control system in the regulation system 3, and the control system in the regulation system 3 controls the driving device 34 to run quickly, and combines the signal detected by the pressure detection system to change the position and posture of the photovoltaic panel 22; for example, when in a strong wind environment, the driving device 34 drives the photovoltaic panel 22 to deflect in a certain direction. When the pressure detected by the pressure detection system gradually decreases, the driving device 34 continues to drive the photovoltaic panel 22 to deflect in this direction until the pressure value detected by the pressure detection system reaches a minimum; when the pressure detected by the pressure detection system gradually increases, the driving device 34 drives the photovoltaic panel 22 to deflect in another direction. At this time, the pressure detected by the pressure detection system begins to gradually decrease until the pressure value detected by the pressure detection system reaches a minimum.

[0054] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
