Description

Greenhouse solar power generation device Technical Field

[0001] The present invention relates to the technical field of solar power generation systems, and mainly relates to a greenhouse solar power generation device that can improve greenhouse solar power generation efficiency and appropriate light transmittance. Background Art

[0002] Greenhouses provide adequate insulation from external wind and rain, creating an optimal growth environment for organisms within. They typically feature a base frame consisting of several vertical frames and several horizontal racks. A semicircular or triangular top frame is placed above the base frame. Various roofing materials, such as agricultural film, mesh, and transparent panels, are placed on the outside and top of the base frame. These roofing materials also provide appropriate light transmittance, air permeability, and shading beneath the greenhouse.

[0003] To improve the efficiency of greenhouses, solar panels can be installed below or above the greenhouse's roof. Although the solar panels installed below the roof can block external wind and rain, external sunlight must first penetrate the roof material of the roof before being projected onto the light-receiving surface of the solar panels that can receive light and generate electricity, causing light energy attenuation and affecting power generation efficiency. When the solar panels are installed above the greenhouse, they are generally flat on the roof or a solar panel rack is installed on the roof, and the solar panels can be installed at an angle relative to the ground.

[0004] However, the aforementioned structure will cause a dark area to form under the solar panels, affecting the growth of organisms in the dark area of ​​the greenhouse. In addition, the fixed inclination of the solar panels cannot adapt to changes in wind speed, causing strong winds to cause the solar panels to be blown off, damaged, and lost.

[0005] For example, the solar power generation devices disclosed in Taiwan Patents TWI643446, TWI599788, TWM518820, and TWM517476 include an adjustment device disposed below one side of one or more solar panels, and the adjustment device can adjust the angle of the solar panel according to the direction of sunlight.

[0006] However, the aforementioned adjustment device can only drive one or a fixed number of solar panels to change their angles. When more solar panels are required for power generation, more adjustment devices must be installed, which increases costs and is inconvenient to install. Moreover, when the structure is installed above a greenhouse, it will occupy a large amount of space above the greenhouse, and it is still difficult to control the lighting effect below the greenhouse.

[0007] Summary of the Invention

[0008] The object of the present invention is to provide a greenhouse solar power generation device that can improve the power generation efficiency of solar panels and provide appropriate light transmittance, and can stably adjust the angle at low cost.

[0010] Furthermore, the two outer sides of the solar panel have a first light-receiving surface and a second light-receiving surface for receiving light to generate electricity.

[0011] Furthermore, the greenhouse body has multiple support columns, and horizontal frames in the front and rear directions are arranged above the support columns; the roof frame is combined with the horizontal frame and is arranged on one side above the horizontal frame; and the column is vertically arranged above the horizontal frame, and the bottom is fixed to the horizontal frame.

The upper frame and the lower frame are connected by the connecting plates, and space is provided between the upper frame, the lower frame, and the connecting plates for assembling a plurality of solar panels in series. A pivot seat is provided at the upper end of the column. The shaft joint is provided at the center of the front and rear ends of the combined frame and is engaged with the pivot seat. The shaft joints of adjacent combined frames are coaxially connected in series, so that the multiple combined frames rotate in conjunction.

[0013] Furthermore, a combination portion is protruded from one side of the connecting plate, and the shaft joint portion is a straight rod. The shaft joint portion is combined with a plurality of combination portions and is arranged on a side corresponding to the light-receiving surface of the solar panel.

[0014] Furthermore, at least one light-reflecting shielding reflective material is provided below the roof frame of the greenhouse body.

[0015] Furthermore, the invention further comprises at least one connecting member, which is arranged between two adjacent solar modules.

[0016] Furthermore, the combined frame has an upper frame, a lower frame, multiple vertical frames, and multiple axis joints. The upper frame and the lower frame are respectively arranged in parallel on the upper and lower sides of the solar panel, and multiple solar panels are continuously arranged between the upper frame and the lower frame; the vertical frame is arranged perpendicular to the upper frame and the lower frame, and the axis joint is arranged on the vertical frames on both sides of the axial direction of the solar module; the connecting member is arranged between the vertical frames of two adjacent solar modules, and the two sides of the connecting member are abutted and fixed to the two vertical frames.

[0017] Furthermore, a connecting portion is provided at the periphery of the solar panel, and a connecting hole is provided on the connecting portion; and a through-hole is provided on the vertical frame corresponding to the position of the connecting hole of the solar panel, and a joint element is inserted through the through-hole and the connecting hole to fix the vertical frame to the solar panel, and the upper and lower ends of the vertical frame are fixed to the upper frame and the lower frame respectively.

[0019] The solar panel of the present invention can stably adjust the angles of multiple serially arranged solar modules by means of the shaft joint with only one actuating device, thereby reducing costs, being easy to install, being able to extend the required light-receiving power generation area, and having better power generation efficiency.

[0020] During typhoons or other strong outdoor wind conditions, the actuator can rotate the solar modules to minimize wind resistance or position them horizontally relative to the ground. This prevents strong winds from directly impacting the solar panels, causing the racks, columns, and solar panels to shift or become damaged.

[0021] Furthermore, during normal operation, the solar panel can be positioned vertically relative to the ground. Therefore, when viewed from above the greenhouse body, the solar panel does not significantly obstruct the top of the greenhouse body, thereby maintaining the proper light transmittance of the greenhouse body and providing a favorable growth environment for sunlight-requiring organisms below. In the present invention, when sunlight is projected onto the roofing material above, if the roofing material has excellent light transmittance, most of the light can be projected downward into the greenhouse body. Furthermore, some of the sunlight can be reflected by the roofing material onto the first or second light-receiving surface of the solar panel to generate electricity. Furthermore, when the sun is in different directions in the morning or afternoon, the primary emitted light can be projected onto the first light-receiving surface or displaced to the second light-receiving surface on the other side. Furthermore, the present invention can be adjusted to an optimal sunlight angle, thereby providing improved power generation efficiency when sunlight is present. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] DETAILED DESCRIPTION

[0044] In the following embodiments, similar functional elements of the present invention are indicated by the same figure numbers. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0045] 1 to 4 , a first embodiment of the present invention includes at least one greenhouse body 1, a plurality of solar modules 2, a plurality of columns 3, and at least one actuating device 4. The greenhouse body 1 has a plurality of support columns 11 on the left and right sides. Horizontal frames 12 in the front and rear directions are arranged above the support columns 11. The horizontal frames 12 may have a drainage function and are combined with a semicircular roof frame 13 on one side of the upper portion. In other embodiments, the roof frame 13 may also have other shapes. A roofing material 14 is laid on the roof frame 13. The roofing material 14 may be agricultural film, a mesh, a transparent plate, an opaque plate, a translucent material, a semi-translucent material, an opaque material, or other appropriate materials. A reinforcing truss 15 is arranged below the roof frame 13. A light-shielding and reflective material 16 that can be deployed or retracted and can block and reflect light is also arranged below the roof frame 13.

[0046] The solar module 2 includes a plurality of combination frames 21 and a plurality of solar panels 22. The combination frame 21 is a straight bar body having an upper and lower parallel straight bar upper frame 211, a straight bar lower frame 212, and a plurality of connecting plates 213. The upper frame 211 and the lower frame 212 are connected by the connecting plates 213, and a setting space 214 is provided between the upper frame 211, the lower frame 212, and the connecting plates 213. A shaft joint 215 is provided at the center of the front and rear ends of the combination frame 2. In this embodiment, multiple The plurality of combination racks 21 are configured such that the shaft joints 215 of adjacent combination racks 2 are coaxially connected in series and assembled, and the plurality of combination racks 21 can be rotated in series. The two outer sides of the solar panel 22 have a first light-receiving surface 221 and a second light-receiving surface 222 for receiving light and generating electricity, and are arranged in series in the installation space 214 of the combination rack 21, so that one side of the combination rack 21 has a plurality of continuously arranged first light-receiving surfaces 221, and the opposite side has a plurality of continuously arranged second light-receiving surfaces 222.

[0047] The upright post 3 is vertically disposed above the horizontal frame 12 , with its bottom fixed to the horizontal frame 12 and a pivot seat 31 disposed at its upper end for engaging with the shaft engaging portion 215 of the assembly frame 21 of the solar module 2 .

[0048] The actuating device 4 has an actuating end 41 that engages with the shaft joint 215 of the assembly frame 21 of the solar module 2 located at the rear side, and can drive the solar module 2 located at the rear side to be positioned vertically, horizontally, or at another appropriate angle relative to the ground. The actuating device 4 can have a hydraulic rotation mechanism, a pneumatic rotation mechanism, or a motor mechanism (not shown), or a knob that can be manually rotated. It can also have a detection device (not shown) that can detect the direction of sunlight, and the detection result of the detection device can drive the solar module 2 to rotate to an appropriate sunlight angle.

[0049] The solar modules 2 of the present invention are mounted on the greenhouse body 1 at a location on the horizontal frame 12, which provides better support, by means of columns 3. Furthermore, the solar panels 22 of the present invention can be normally positioned vertically relative to the ground. Therefore, as shown in FIG3 , in this embodiment, when viewed from above the greenhouse body 1, each solar panel 22 has a width of W2, and the total width of the solar panels 22 is W2×6, which is much smaller than the width W1 of each greenhouse body 1. Given the same length, the solar panels 22 block minimal light. Furthermore, the solar panels 22 are positioned above the corresponding opaque horizontal frame 12, so they do not block the top of the greenhouse body 1. This allows the greenhouse body 1 to have a light transmittance similar to that of a plant without solar panels 22, providing a favorable growth environment for sunlight-requiring plants below the greenhouse.

[0050] Please refer to Figures 4 and 5, which respectively illustrate the power generation state of the present invention when the sun is located above and to the side of the greenhouse body 1. When sunlight is projected onto the roofing material 14 above, if the roofing material 14 has good light transmittance, most of the light can be projected downward into the greenhouse body 1, while part of the sunlight can be reflected by the roofing material 14 onto the first light-receiving surface 221 or the second light-receiving surface 222 of the solar panel 22 to generate electricity. Furthermore, when the sun is in different directions in the morning or afternoon, its main emitted light can be projected onto the first light-receiving surface 221 or shifted to the second light-receiving surface 222 on the other side. Therefore, the present invention can provide power generation by receiving sunlight when there is sunlight, and can also receive direct sunlight and reflect sunlight for better power generation efficiency. Furthermore, the present invention can also achieve both good light transmittance and power generation efficiency by using an actuator to shift the solar panel to a preferred sunlight angle (not shown) to improve power generation efficiency.

[0051] Please refer to FIG6 . When mushrooms or other organisms that do not require sunlight (not shown) are grown below the greenhouse body 1 of the present invention, the roof material 14 can be made of an opaque and highly reflective material. Therefore, in addition to directly irradiating the first and second light-receiving surfaces 221 and 222 of the solar panel 22 to generate electricity, most of the light from the external sunlight that irradiates the roof material 14 can be reflected to the first and second light-receiving surfaces 221 and 222 of the solar panel 22, thereby achieving better power generation efficiency.

[0052] Please refer to Figure 7. The present invention can deploy the shielding reflective material 16 in the greenhouse body 1 at noon when the sunlight is strong or as needed. The shielding reflective material 16 can prevent strong light from irradiating organisms and affecting their growth, and can provide a first light-receiving surface 221 or a second light-receiving surface 222 that reflects most of the light to the upper solar panel 22, thereby improving the efficiency of power generation by reflected light.

[0053] Please refer to Figures 8 and 9. When there is a typhoon or other strong outdoor wind conditions, the actuator 4 can rotate the shaft joint 215 to allow the solar panel 22 to have a minimum wind resistance angle or be set horizontally relative to the ground. This can prevent strong external wind from directly hitting the first light-receiving surface 221 or the second light-receiving surface 222, causing the combined frame 21, the column 3, and the solar panel 22 to deviate or be damaged. In addition, the solar panel 22 can have the effect of shielding the horizontal frame 12 below.

[0054] Please refer to Figure 10, which is a schematic diagram of the structure of the assembly rack 21 according to the second embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the assembly rack 21 has a protruding assembly portion 216 on one side of the connecting plate 213. The shaft joint portion 215 is a straight rod that is combined with the assembly portions 216 of the plurality of assembly racks 21 and is provided on the side of the first light-receiving surface 221 of the corresponding solar panel 22. One end of the shaft joint portion 215 is linked to the actuator 4 and can drive each solar module 2 to rotate corresponding to the vertical or horizontal displacement or other angular movement of the ground.

[0055] Please refer to Figure 11 which is a third embodiment of the present invention. The third embodiment is similar to the first embodiment, except that two expandable or retractable shielding reflective materials 16 are provided under the roof frame 13 on the greenhouse body 1. When the two shielding reflective materials 16 are expanded, one end is located on the side of the greenhouse body 1 and the other end is located at different heights in the center of the roof frame 13. When the two shielding reflective materials 16 are expanded, they can be arranged obliquely corresponding to the ground, and a breathable separation space 161 is provided between the two shielding reflective materials 16.

[0056] In the present invention, when the sunlight is strong or according to the needs, the shielding reflective material 16 can be unfolded, and its oblique angle can directly reflect most of the light to the solar panel 22 to have better power generation efficiency. The separation space 161 can improve the ventilation and heat resistance of the greenhouse body.

[0057] Please refer to Figures 12 and 13 which are the fourth embodiment of the present invention. The fourth embodiment is similar to the first embodiment, with the difference that the roof frame 13 is triangular in shape, and a straight column 131 on one side corresponding to the ground approximately perpendicular can be combined with the column 3 to improve the stability of the column 3 combination, and a retractable breathable or unfolded airtight curtain 132 can be set at the position of the straight column 131, and a shielding reflective material 16 that can be unfolded or retracted in a direction approximately parallel to the top of the roof frame 13 is set, and as shown in Figure 13, when the sunlight is strong or the shielding reflective material 16 can be unfolded as needed, it can be set obliquely corresponding to the ground, and its oblique angle can directly reflect most of the light to the solar panel 22 for better power generation efficiency.

[0058] Please refer to Figures 14 to 20 which are the fifth embodiment of the present invention. The fifth embodiment is the same as the first embodiment and is both installed on the greenhouse body. The main difference lies in the solar module and the column structure. The solar module 5 of the fifth embodiment includes a plurality of assembly frames 50 and a plurality of solar panels 22. The solar panels 22 are provided with connecting portions 223 on the periphery thereof, and the connecting portions 223 are provided with assembly holes 224.

[0059] The assembly frame 50 comprises a straight upper frame 51, a straight lower frame 52, a plurality of straight vertical frames 53, and a plurality of axis joints 55. The upper frame 51 and the lower frame 52 are arranged parallel to each other on the upper and lower sides of the solar panel 22, respectively. A plurality of solar panels 22 are arranged continuously between the upper frame 51 and the lower frame 52. The vertical frame 53 is arranged perpendicularly to the upper frame 51 and the lower frame 52. A first through-hole 531 is provided in the vertical frame 53 corresponding to the assembly hole 224 of the connecting portion 223 on the second light-receiving surface 222 of the solar panel 22. A joint member 54 is inserted through the first through-hole 531 and the assembly hole 224 to securely connect the vertical frame 53 to the solar panel 22. The vertical frame 53 and the upper frame 51 are provided with third engagement holes 532 and first engagement holes 511 at corresponding positions, respectively. The vertical frame 53 and the lower frame 52 are provided with fourth engagement holes 533 and second engagement holes 521 at corresponding positions, respectively. These two sets of engagement holes are secured by engagement elements 54. In other embodiments, the vertical frame 53, the upper frame 51, and the lower frame 52 can also be secured by welding or other means. Furthermore, the shaft engagement portion 55 is provided on the vertical frame 53 on both axial sides of the solar module 5 by engagement elements 54. In other embodiments, the shaft engagement portion 55 can also be secured to the vertical frame 53 by welding. In this embodiment, the shaft engagement portion 55 has a square second through-hole 551 protruding from the vertical frame 53 and is provided with a plurality of sixth engagement holes 552.

[0060] The fifth embodiment of the upright column 6 is vertically mounted relative to the ground, with a rectangular support platform 61 disposed at its top. A bearing 62 is centrally disposed within the support platform 61. The bearing 62 comprises a base 621 and a rotating shaft 622. The base 621 is fixed to the support platform 61, while the rotating shaft 622 is rotatable within the base 621. Square connecting posts 623 are projected from both ends. The upright column 63 further comprises a plurality of connecting blocks 63. Each connecting block 63 comprises a connecting plate 631 having a seventh engaging hole 632 corresponding to the sixth engaging hole 552 of the shaft engaging portion 55. Furthermore, a square engaging post 633 is projected from one side of the connecting plate 631, which is adapted to pass through the second through-hole 551 of the shaft engaging portion 55 and to engage with the shaft engaging portion 55. The engaging post 633 comprises a square fitting hole 634 that fits over the connecting plate 623 and engages with the rotating shaft 622. In other embodiments, the second through-hole 551 , the connecting post 623 , the engaging post 633 , and the fitting hole 634 may also be other non-circular shapes or shapes that can achieve the aforementioned linkage purpose, and are not limited to square shapes.

[0061] The connector 7 is a rectangular body, with two sides approximately corresponding to the length of the vertical frame 53 of the solar module 2, and a central reinforcement frame 71. In other embodiments, the connector 7 may also be a plate or other body. Eighth and fifth engagement holes 72 and 534 are provided on both sides of the connector 7 and at positions corresponding to the vertical frame 53 of the adjacent solar module 2, respectively. These are connected by a coupling element 54, and the actuating end 41 of the actuating device 4 of this embodiment is interlocked with the shaft coupling portion 55.

[0062] The present invention can be installed with an appropriate number of solar modules 5 to suit the installation environment and power generation requirements. The solar modules 5 can be prefabricated as shown in Figures 15 and 16. As shown in Figures 17 to 19, the column 6 has been previously positioned above the greenhouse body (not shown) and can be used to suspend the solar modules 5, with the shaft coupling portion 55 directly suspended on the support platform 61 of the column 6. The second through-hole 551 of the shaft coupling portion 55 aligns with the connecting post 623 of the bearing 62. The coupling post 633 of the connecting block 63 is inserted through the second through-hole 551, and the fitting hole 634 of the coupling post 633 fits the connecting post 623. The coupling element 54 is inserted through the seventh fitting hole 632 of the connecting block 63 and the sixth fitting hole 552 of the shaft coupling portion 55, allowing the shaft coupling portion 55 to interlock with the rotating shaft 622 of the bearing 62. Therefore, this embodiment is suitable for a hanging machine, which can hang the assembled solar modules 5 onto the supporting platform 61 above the greenhouse body for further assembly, and can be quickly installed on site.

[0063] After assembly, the present invention installs a connector 7 between two adjacent solar modules 5. The connector 7 is positioned so that its two sides abut against the vertical frames 53 of the two adjacent solar modules 5. The connector 7 is then secured to the two solar modules 5 by inserting the engaging elements 54 through the eighth engaging holes 72 and the fifth engaging holes 534. Furthermore, the actuator 4 is located at the outer end of the entire solar power generation device. The actuator end 41 is coupled to the shaft engaging portion 55 to complete the assembly shown in Figure 14, making installation easier. Furthermore, the actuator 4's location outside the solar power generation device facilitates maintenance.

[0064] After the assembly of the present invention, the centers of the first light-receiving surface 221 and the second light-receiving surface 222 of the solar panel 22 will not be covered by the assembly frame 50 or other components, so that the first and second light-receiving surfaces 221 and 222 can both receive light and generate electricity over a large area, and have better power generation efficiency than the second embodiment shown in Figure 10 where the long rod-shaped shaft joint 215 partially covers the first light-receiving surface 221.

[0065] Referring to Figures 14 and 20 , after the present invention is assembled, each solar module 5 can be stably supported by the supporting platform 61 of the column 6. Furthermore, when the actuator 4 drives the connected solar module 5 to rotate, the rotational torque can be transmitted to the connector 7 of relatively good strength, and then transmitted from the connector 7 to another adjacent solar module 5. The rotational torque can then be transmitted to the other connectors 7 and solar modules 5 in sequence. Furthermore, the side of the connector 7 is planar and fits in with the side of the vertical frame 53 of the solar module 5. Therefore, when the solar module 5 at one end rotates about the rotating shaft 622, it can stably link the other solar modules 5 to rotate synchronously, allowing each solar module 5 to be synchronously adjusted to the same light receiving angle, thus providing better adjustment stability.

[0066] When the solar modules 5 of this embodiment rotate, their torque is primarily applied to the connector 7, reducing the load on the rotating shaft 622. Furthermore, the force applied to the rotating shaft 622 can be transmitted to the connecting block 63 and the shaft joint 55, distributing the force and promoting smoother rotation of the solar modules 5. Therefore, this embodiment can simultaneously drive the rotation of all solar modules 5 when multiple solar modules 5 are arranged in series. Furthermore, this embodiment provides greater rotational stability than the first embodiment, which directly connects adjacent solar modules at their shaft joints.

[0067] Therefore, as described above, the present invention has the advantages of easy installation, extensibility to meet the requirements of the light-receiving power generation area, better power generation efficiency, and more stable adjustment angle. The aforementioned embodiments are illustrative of the present invention and are not limiting of the present invention. Any equivalent changes based on the present invention should also fall within the scope of the present invention.
