Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a stackable multi-angle light-collecting photovoltaic panel. Background Technology

[0002] With increasing environmental awareness and the advancement of carbon neutrality goals, photovoltaic (PV) power generation, as a representative of clean energy, is widely used in the power generation field. It converts solar energy into electricity, reducing dependence on traditional fossil fuels and demonstrating environmental friendliness and sustainability. In agro-photovoltaic power plants that combine agriculture and PV, photovoltaic panels are installed above farmland to achieve comprehensive land utilization. However, existing PV power plants still have certain shortcomings in their application.

[0003] Currently installed agricultural-solar hybrid photovoltaic power stations have a certain installation spacing between each group of photovoltaic panels to increase power generation efficiency and prevent their shadows from affecting each other. However, since the position of the sun and the intensity of sunlight gradually change over time, and the area of ​​shadow covered by the photovoltaic panels gradually decreases as the position of the sun changes, crops planted between the photovoltaic panels are still easily exposed to strong direct sunlight at certain times, such as at noon. Excessive sunlight may cause them to grow poorly and hinder their growth. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0025] According to an embodiment of the present invention, a stackable multi-angle light-collecting photovoltaic panel is provided, comprising: a mounting frame 1, a tilt adjustment mechanism, and a support column 3. The mounting frame 1 has a first mounting cavity 11 and a second mounting cavity 12 with an opening on one side. The first mounting cavity 11 is located above the second mounting cavity 12. A first photovoltaic panel 13 is disposed in the first mounting cavity 11, and a second photovoltaic panel 14 is disposed in the second mounting cavity 12. The first photovoltaic panel 13 or the second photovoltaic panel 14 can slide out of the first mounting cavity 11 or the second mounting cavity 12 along the opening. A first auxiliary frame 15 is provided at the bottom end of the mounting frame 1, and the first auxiliary frame 15 has a first receiving cavity 15. 1; The tilt adjustment mechanism includes: a rotating component 21 and a first connecting rod 22, the fixed end of the rotating component 21 is connected to the inner wall of the first receiving cavity 151, and the driving end of the rotating component 21 is connected to one end of the first connecting rod 22; the top outer wall of the support column 3 is connected to the other end of the connecting rod; the first photovoltaic panel 13 or the second photovoltaic panel 14 has the rotating component 21 driving the mounting frame 1 to tilt, so that the first photovoltaic panel 13 or the second photovoltaic panel 14 slides out of the unfolded state of the mounting frame 1, and the rotating component 21 driving the mounting frame 1 back to the upright state, so that the first photovoltaic panel 13 or the second photovoltaic panel 14 slides into the retracted state of the mounting frame 1.

[0026] The outer wall of one side of the mounting frame 1 has a first mounting cavity 11 and a second mounting cavity 12 arranged vertically. The first mounting cavity 11 is used to install the first photovoltaic panel 13, and the second mounting cavity 12 is used to install the second photovoltaic panel 14. The first photovoltaic panel 13 or the second photovoltaic panel 14 is slidably disposed in the first mounting cavity 11 or the second mounting cavity 12, so that the first photovoltaic panel 13 or the second photovoltaic panel 14 can slide along the length direction of the mounting frame 1. When the mounting frame 1 is driven by the tilt adjustment mechanism to tilt the openings of the first mounting cavity 11 and the second mounting cavity 12 downward, the first photovoltaic panel 13 or the second photovoltaic panel 14 slides outward under the action of gravity and slides out of the first mounting cavity 11 or the second mounting cavity 12 to form an unfolded state; when the mounting frame 1 is driven by the tilt adjustment mechanism to return to the center and tilt upward at a small angle, the first photovoltaic panel 13 or the second photovoltaic panel 14 returns to the first mounting cavity 11 by its own weight, forming a retracted state, thereby realizing the unfolding and folding storage of the first photovoltaic panel 13 or the second photovoltaic panel 14. In this embodiment, the first photovoltaic panel 13 can slide along the first mounting cavity 11, and the second photovoltaic panel 14 is fixed in the second mounting cavity 12.

[0027] The mounting frame 1 can tilt and rotate around the top of the support column 3. The fixed end of the rotating component 21 is fixedly connected to the auxiliary frame. When the rotating component 21 is activated, the driving force of the rotating component 21 is transmitted to the mounting frame 1 through the first connecting rod 22, causing the mounting frame 1 to tilt relative to the support column 3. During the tilting process of the mounting frame 1, the first photovoltaic panel 13 or the second photovoltaic panel 14 slides out of the first mounting cavity 11 to form an unfolded state, thereby increasing the light-receiving area and improving the incident angle, while also shading crops to prevent them from receiving excessive sunlight. When the rotating component 21 rotates in the opposite direction to drive the mounting frame 1 back to the upright position, the first photovoltaic panel 13 or the second photovoltaic panel 14 slides back into the first mounting cavity 11 or the second mounting cavity 12 to form a retracted state, reducing the wind-receiving area and facilitating the protection and maintenance of the first photovoltaic panel 13 or the second photovoltaic panel 14.

[0028] In one embodiment, a second auxiliary frame 16 is also provided at the bottom of the mounting frame 1. The second auxiliary frame 16 has a second receiving cavity 161. A fixing mechanism is provided in the second receiving cavity 161. The fixing mechanism includes a first pushing member 41 and a second connecting rod 42. The fixed end of the first pushing member 41 is connected to the inner wall of the second receiving cavity 161. The driving end of the first pushing member 41 is connected to one end of the second connecting rod 42. The other end of the second connecting rod 42 is connected to the top outer wall of the support column 3.

[0029] Specifically, the first pushing member 41 is an electric push rod, with its fixed end fixed to the side wall of the receiving cavity of the auxiliary frame. The position of the support column 3 and the mounting frame 1 is fixed by the telescopic movement of the driving end. When the rotating member 21 drives the mounting frame 1 to adjust the tilt angle, the driving end of the first pushing member 41 retracts. When it is necessary to fix the mounting frame 1, the driving end of the first pushing member 41 extends and connects with the second connecting rod 42, so that the second connecting rod 42 forms a stable force channel between the support column 3 and the mounting frame 1, thereby supporting and fixing the current pitch angle of the mounting frame 1, keeping the mounting frame 1 stable at the target angle, and preventing the mounting frame 1 from shifting its attitude due to wind load, inertia, or vibration. When it is necessary to adjust the tilt angle of the mounting frame 1 again, the driving end of the first driving member retracts again to continue the tilt angle adjustment of the mounting frame 1.

[0030] In one embodiment, a rotating hole 221 is provided at one end of the connecting rod, and a plurality of retaining strips 222 are provided in the rotating hole 221. The plurality of retaining strips 222 are arranged circumferentially along the inner wall of the rotating hole 221. The driving end of the rotating member 21 is inserted into the rotating hole 221 on the first connecting rod 22, and the driving end of the first pushing member 41 is inserted into the rotating hole 221 on the second connecting rod 42.

[0031] Specifically, a circular rotating hole 221 is provided at one end of the first connecting rod 22 and the second connecting rod 42. The diameter of the rotating hole 221 matches the size of the driving end of the rotating member 21 and the first pushing member 41 to ensure a tight fit after insertion and to form a fixed connection. The rotating hole 221 serves to limit the connection, forming a stable connection interface between the rotating member 21 and the first connecting rod 22, and between the first pushing member 41 and the second connecting rod 42, preventing the mounting frame 1 from loosening, shifting, or detaching during tilt adjustment or fixing. The retaining strips 222 are evenly distributed on the inner wall of the rotating hole 221, with multiple retaining strips 222 spaced apart along the circumference of the rotating hole 221. The retaining strips 222 are integrally formed by machining, and each retaining strip 222 can be strip-shaped, arc-shaped, or wedge-shaped. In this embodiment, the retaining strip 222 is strip-shaped, ensuring a stable positioning fit after the driving end of the rotating member 21 or the first pushing member 41 is inserted into the rotating hole 221.

[0032] During installation, after the driving ends of the rotating component 21 and the first pushing component 41 are inserted into the rotating hole 221, they abut against the outer wall of the retaining strip 222, forming multi-point support and precise positioning. Multiple retaining strips 222 are arranged circumferentially within the rotating hole 221, making it less prone to displacement or wobbling of the driving ends of the rotating component 21 and the first pushing component 41 under stress, thereby improving the stability and anti-loosening ability of the fixed connection. Simultaneously, the retaining strips 222 can also absorb mechanical vibration to a certain extent, reducing stress concentration at the connection and preventing structural loosening or wear due to long-term operation.

[0033] In one embodiment, a light-transmitting plate 5 is provided at the bottom of the mounting frame 1, and an annular baffle 51 is provided in both the first accommodating cavity 151 and the second accommodating cavity 161. The bottom of the light-transmitting plate 5 is connected to the outer wall of the annular baffle 51. An annular rotating member 6 is sleeved on the outer wall of both the first connecting rod 22 and the second connecting rod 42. The outer wall of the annular rotating member 6 is connected to the inner wall of the annular baffle 51.

[0034] Specifically, the light-transmitting plate 5 is a flat, transparent component, which can be made of tempered glass, polycarbonate sheet, or transparent composite material. It is installed at the bottom of the mounting frame 1, ensuring the structural strength of the mounting frame 1 while allowing light to pass through and maintaining the lighting environment in the area below the mounting frame 1. An auxiliary frame is installed at the bottom of the light-transmitting plate 5, and an annular baffle 51 is set in the receiving cavity of the auxiliary frame. The bottom surface of the light-transmitting plate 5 is connected to the outer wall of the annular baffle 51, and the inner wall of the annular baffle 51 is in contact with the outer wall of the annular rotating component 6.

[0035] The annular rotating component 6 is made of bearing, and its outer wall is connected to the inner wall of the annular baffle 51. The inner wall is connected to the outer wall of the first connecting rod 22, so that a stable rotational force transmission path is formed between the first connecting rod 22 and the mounting frame 1, ensuring that the mounting frame 1 has good anti-deformation ability and wear resistance during the tilt adjustment process.

[0036] In one embodiment, an annular groove 511 is formed on the inner wall of the annular baffle 51, an auxiliary groove 223 is formed on the outer wall of the connecting rod, the outer wall of the annular rotating member 6 is fitted into the annular groove 511, and the inner wall of the annular rotating member 6 is fitted into the auxiliary groove 223.

[0037] Specifically, the annular groove 511 is circumferentially opened along the inner wall of the annular baffle 51, and its cross-section is a rectangular slot, used to limit the lateral displacement of the annular rotating member 6. The auxiliary groove 223 is also annular, opened on the outer wall of the first connecting rod 22, and its opening position matches that of the annular groove 511, forming a circumferential fitting space. The annular rotating member 6 is placed between the annular groove 511 and the auxiliary groove 223, with its outer wall fitting against the inner wall of the annular groove 511 and its inner wall fitting against the outer wall of the auxiliary groove 223, thereby forming a stable fitting position in the radial direction.

[0038] In one embodiment, two mounting slots 17 are provided on both sides of the top of the mounting frame 1. Two second pushers 18 are respectively provided in the two mounting slots 17. Sliding grooves 131 are respectively provided on both sides of the top surface of the first photovoltaic panel 13. The driving end of the second pusher 18 is slidably connected to the sliding groove 131.

[0039] Specifically, the second pusher 18 is also an electric push rod, whose output end can slide and connect with the groove 131 on the first photovoltaic panel 13 when it extends, so as to provide sliding guidance during the process of the first photovoltaic panel 13 sliding into or out of the first mounting cavity 11.

[0040] In one embodiment, fixing holes 132 are respectively provided at both ends of the slide 131, and the output end of the second pusher 18 can be inserted into the fixing holes 132 to fix the first photovoltaic panel 13.

[0041] Specifically, the output end of the second pusher 18 can be inserted into the fixing hole 132 to fix the first photovoltaic panel 13. When the first photovoltaic panel 13 is in the unfolded or retracted state, the output end of the second pusher 18 engages with the fixing hole 132 to fix the first photovoltaic panel 13. When the first photovoltaic panel 13 is sliding, the output end of the second pusher 18 retracts from the fixing hole 132 and slides into the slide groove 131 to prevent the first photovoltaic panel 13 from sliding out of the first mounting cavity 11 or detaching from the mounting frame 1.

[0042] In one embodiment, a plurality of detection slots 19 are spaced apart on one side of the top surface of the mounting frame 1, and each detection slot 19 is provided with a photosensitive detector 191, which is electrically connected to the rotating member 21.

[0043] Specifically, multiple detection slots 19 are formed along the width of one side of the top surface of the mounting frame 1, and photodetectors 191 are installed in the detection slots 19. The depth of the detection slots 19 can be determined according to the size of the photodetectors 191, so that the photosensitive surface of the photodetectors 191 is basically flush with the top surface of the mounting frame 1, ensuring direct detection of external light.

[0044] The photodetector 191 is used to detect the distribution of light intensity from different directions in real time. When the photodetector 191 in the detection slot 19 collects the light intensity change signal, the signal is transmitted to the control terminal of the rotating component 21 via a wire. The rotating component 21 adjusts its rotation direction and angle according to the signal difference output by the photodetector 191, thereby driving the mounting frame 1 to achieve pitch adjustment.

[0045] The photodetector 191 can be a photodiode, a photoresistor, or an integrated light sensing module, and its electrical connection lines can be led out to the control circuit module of the rotating component 21 through a waterproof connector. The detection slot 19 can be equipped with a transparent cover to prevent dust, moisture, or foreign objects from entering, while ensuring the cleanliness of the photosensitive surface of the photodetector 191 and the detection sensitivity.

[0046] In one embodiment, a plurality of photovoltaic power generation units 133 are spaced apart on the first photovoltaic panel 13 and the second photovoltaic panel 14 along their width direction, and the photovoltaic power generation units 133 on the first photovoltaic panel 13 and the second photovoltaic panel 14 are alternately arranged.

[0047] Specifically, both the first photovoltaic panel 13 and the second photovoltaic panel 14 adopt a semi-transparent photovoltaic structure. Multiple rectangular photovoltaic power generation units 133 are arranged sequentially along the width direction on each photovoltaic panel. Light transmission gaps are provided between adjacent photovoltaic power generation units 133 to allow some light to pass through the photovoltaic panel and illuminate the area below.

[0048] To improve the overall uniformity of light reception, the photovoltaic power generation units 133 on the first photovoltaic panel 13 and the second photovoltaic panel 14 are arranged in an alternating staggered manner. That is, when the position corresponding to a photovoltaic power generation unit 133 on the first photovoltaic panel 13 is empty, a photovoltaic power generation unit 133 is placed at the same position on the second photovoltaic panel 14; conversely, when the second photovoltaic panel 14 is in an empty position, a photovoltaic power generation unit 133 is placed at the corresponding position on the first photovoltaic panel 13. Through this staggered arrangement structure, the two photovoltaic panels can achieve a balanced distribution of light when they are stacked or unfolded, avoiding power loss caused by local shading. Since multiple multi-angle light-collecting photovoltaic panels are evenly spaced in the farmland, even if the first photovoltaic panel 13 is located below the second photovoltaic panel 14 of the adjacent multi-angle light-collecting photovoltaic panel after it slides out, the alternating arrangement of the photovoltaic power generation units 133 will not significantly affect the power generation efficiency, and it can still generate a certain amount of power.

[0049] In one embodiment, a rubber pad 111 is provided at the opening of the first mounting cavity 11.

[0050] Specifically, rubber pads 111 are provided at both ends of the opening of the first mounting cavity 11. The rubber pads 111 can be made of weather-resistant rubber materials, such as silicone rubber, fluororubber, or EPDM rubber. The cross-sectional shape of the rubber pads 111 is rectangular, and its thickness is determined according to the gap size between the first photovoltaic panel 13 and the first mounting cavity 11, so as to ensure that appropriate contact pressure is formed when the first photovoltaic panel 13 slides in or out.

[0051] The rubber pad 111 serves as a buffer and limiter, preventing the first photovoltaic panel 13 from impacting the inner wall of the mounting frame 1 due to excessive inertia, effectively reducing the impact force at the sliding end. The rubber pad 111 also has good elastic recovery properties, maintaining a stable sealing state during the sliding out or in process of the first photovoltaic panel 13, preventing external impurities such as dust and moisture from entering the interior of the first mounting cavity 11.

[0052] Adjustment process: When the light-receiving angle of the photovoltaic panel needs to be adjusted, the rotating component 21 is activated. Since the fixed end of the rotating component 21 is fixed in the inner cavity and the driving end of the rotating component 21 is fixed to the support column 3, under the action of its driving force, the fixed end of the rotating component 21 drives the mounting frame 1 to make a slight tilt adjustment, causing the mounting frame 1 to pitch and rotate around the support column 3 as the fulcrum. As the mounting frame 1 tilts, the first photovoltaic panel 13 gradually slides out from the first mounting cavity 11 under the action of gravity and the guide structure, forming an unfolded state. At this time, the two photovoltaic panels are relatively staggered, which expands the overall light-receiving area of ​​the photovoltaic panel array and increases the shading area of ​​crops.

[0053] In the evening or during periods of weak sunlight, the rotating component 21 rotates in the opposite direction, causing the mounting frame 1 to return to its upright position. The first photovoltaic panel 13 slides back into the first mounting cavity 11 under its own weight, forming a retracted state to reduce the wind-exposed area and facilitate protection. The fixing mechanism uses the first pushing component 41 and the second connecting rod 42, which are set in the auxiliary frame, to fix the angle between the mounting frame 1 and the support column 3, preventing the mounting frame 1 from swaying due to wind or inertia.

[0054] A second pusher 18 is provided in the mounting groove 17 at the top of the mounting frame 1. The output end of the second pusher 18 is inserted into the fixing holes 132 at both ends of the sliding groove 131 on the top surface of the first photovoltaic panel 13. It plays a fixing role after the photovoltaic panel slides in or out, preventing the first photovoltaic panel 13 from sliding out excessively or detaching from the mounting frame 1.

[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
