Description

Technical Field

[0001] The utility model belongs to the field of flat single-axis tracking brackets, and in particular relates to a flat single-axis tracking bracket with adjustable inclination angle. Background Art

[0002] In recent years, with the continuous attention and support for new energy, photovoltaic power generation technology has made great strides. However, at the same time, the wasteland, barren mountains, wasteland and rooftops that can be used for the construction of photovoltaic power stations are becoming increasingly scarce, which is far from meeting the needs of the market. The photovoltaic industry is facing transformation and upgrading, and coordinated development with other industries has become an important way out. On the other hand, agriculture is also constantly seeking self-breakthroughs. The new industry of photovoltaic agriculture has pioneered the combination of photovoltaic power generation with agricultural development and resource conservation. Due to the commonality and complementarity of photovoltaics and agriculture in land use, the scientific and reasonable combination model of "agriculture + photovoltaics" is regarded as one of the important ways out for the photovoltaic industry in the difficult problem of transformation and development.

[0003] In agricultural-photovoltaic complementary projects, the selection of photovoltaic brackets is crucial, which not only affects the efficiency of photovoltaic power generation, but also is related to the growth of crops and the sustainability of agricultural production.

[0004] Most flat single-axis tracking brackets are now used, but traditional flat single-axis tracking brackets only allow rotation in the east-west direction and cannot take into account the changes in the solar altitude angle within a year. Therefore, in order to further increase power generation, flat single-axis with inclination, inclined single-axis and dual-axis tracking are usually used. These forms are suitable for mid- and high-latitude regions.

[0005] The photovoltaic modules with tilted flat single-axis and inclined single-axis tracking brackets have a small and fixed north-south tilt angle and cannot track changes in the sun's north-south incident angle, resulting in limited improvement in power generation. The dual-axis tracking bracket can simultaneously track changes in the sun's east-west and north-south incident angles, significantly improving power generation, but the cost is relatively high.

DETAILED DESCRIPTION

[0034] like Figure 1-7 As shown, a flat single-axis tracking bracket with adjustable inclination angle comprises a main shaft 1 arranged on an existing flat single-axis tracking bracket, and the main shaft 1 extends in the north-south direction, a photovoltaic module 2 is arranged above the main shaft 1, and an inclination adjustment device for adjusting the inclination angle of the photovoltaic module 2 in the north-south direction is arranged between the photovoltaic module 2 and the main shaft 1;

[0035] The tilt adjustment device includes two purlins 3 that are detachably installed at the bottom of the photovoltaic module 2, and the two purlins 3 extend in the east-west direction and are distributed in the north-south direction. The bottoms of the two purlins 3 are respectively detachably connected with a first connecting component 4 and a second connecting component 5. The main shaft 1 is detachably sleeved with a first fastening component 6 and a second fastening component 7 along its length direction. The first connecting component 4 is connected to the first fastening component 6 through a plurality of first bolt kits 8, and the second connecting component 5 is connected to an inclined support frame 10 through a plurality of second bolt kits 9. The other end of the inclined support frame 10 is connected to the second fastening component 7 through a plurality of third bolt kits 11.

[0036] When it is necessary to adjust the north-south inclination angle of the photovoltaic assembly 2 to improve the power generation efficiency due to changes in lighting conditions, seasonal changes, etc., first use a tool to loosen the bolt kit between the first connecting assembly 4 and the first fastening assembly 6 and between the inclined support frame 10 and the second connecting assembly 5 and the second fastening assembly 7, but do not remove it completely. Then, before moving the second fastening assembly 7, the current position of the second fastening assembly 7 can be marked on the main shaft 1 so that it can be restored to the initial state when needed.

[0037] Subsequently, according to the size of the inclination angle to be adjusted, the moving direction and distance of the second fastening component 7 on the main shaft 1 are determined, and then the second fastening component 7 is loosened and moved along the main shaft 1 to a predetermined position, and then the second fastening component 7 is tightened, and one end of the inclined support frame 10 is connected to the second connecting component 5 through the second bolt kit 9, and the other end of the inclined support frame 10 is connected to the second fastening component 7 through the third bolt kit 11, and then the first connecting component 4 is reconnected to the first fastening component 6 through the first bolt kit 8 to ensure a firm connection. At this time, the inclination adjustment of the photovoltaic component 2 in the north-south direction is realized.

[0038] This design, firstly, adjusts the north-south inclination angle of the photovoltaic module 2 through a simple mechanical structure, and combines the existing east-west tracking technology to achieve full tracking of the solar incidence angle within a day and a year. The effect is equivalent to that of a dual-axis tracking bracket, which increases power generation, but greatly reduces the cost compared to a dual-axis tracking bracket.

[0039] Secondly, it can adapt to the lighting characteristics of different latitudes, greatly expanding the application scope of traditional flat single-axis and flat single-axis tracking brackets with inclination. Therefore, whether in high-latitude areas or low-latitude areas, it can be accurately adjusted according to the local solar trajectory to ensure that the photovoltaic module 2 always receives sunlight at the best angle, thereby achieving efficient power generation.

[0040] Thirdly, each component is detachably connected to facilitate installation and disassembly. Therefore, during the installation process, each component can be transported to the installation site separately and then assembled, which reduces the difficulty of transportation and installation. In addition, when a component fails, it can be easily replaced or repaired without having to replace the entire tracking bracket, saving maintenance costs and time.

[0041] Fourthly, the various components are connected by bolt kits, and the connection is firm and reliable, thereby ensuring that the tracking bracket can maintain a stable structure under various harsh environmental conditions and ensure the safe operation of the photovoltaic module 2.

[0042] The first fastening assembly 6 and the second fastening assembly 7 have the same structure. The first fastening assembly 6 includes two fastening plates 61 symmetrically arranged on both sides of the main shaft 1 .

[0043] A fourth bolt set 62 is symmetrically arranged between the two fastening plates 61 and on both sides of the main shaft 1 , and the fourth bolt set 62 squeezes and fixes the two fastening plates 61 and the main shaft 1 together.

[0044] Two fifth connecting ear plates 63 are symmetrically fixedly connected to the top of the fastening plate 61 located above the main shaft 1, and a first serration structure is provided on one side wall of the two fifth connecting ear plates 63 which are away from each other.

[0045] With this design, firstly, the symmetrical arrangement of the fastening plates 61 can make the main shaft 1 bear the force evenly to avoid displacement or deformation, and the bolt kit provides a strong clamping force to prevent loosening, thereby ensuring the stability and reliability of the equipment. At the same time, the fourth connecting ear plate 107 is convenient for connection with other components.

[0046] Secondly, the symmetrical design makes installation simple and intuitive, and the bolt kit can be easily removed, saving maintenance time and cost.

[0047] Furthermore, the specifications of the fastening plate 61 and the bolts and nuts can be adjusted according to the different sizes and requirements of the main shaft 1 to adapt to various application scenarios and meet the needs of frequent adjustment or replacement of the main shaft 1 equipment.

[0048] In addition, the first serration structure provided on the fifth connecting ear plate 63 can increase friction and improve the reliability of the connection, so that during the connection process, the serration structure can engage with the corresponding structure of other components to prevent the connection from loosening and ensure the firmness of the connection.

[0049] The first connecting assembly 4 includes a first connecting plate 41 detachably mounted on the corresponding purlin 3 , two first connecting ear plates 42 are symmetrically arranged at the bottom middle position of the first connecting plate 41 , and the first connecting ear plate 42 and the corresponding fifth connecting ear plate 63 are fastened together by a first bolt kit 8 .

[0050] A second sawtooth structure is provided on one side wall of the two first connecting ear plates 42 that are close to each other, and the second sawtooth structure matches the first sawtooth structure.

[0051] With this design, firstly, the first connecting plate 41 can be detachably installed on the purlin 3, so that the position can be flexibly adjusted according to actual conditions during the installation process, which is convenient for accurate docking with other components; at the same time, when maintenance or replacement of components is required, it can be quickly disassembled, reducing maintenance costs and time.

[0052] Secondly, the first connecting ear plate 42 and the fifth connecting ear plate 63 are fastened together by the first bolt set 8. The bolt connection method is simple and reliable, easy to operate, convenient for installation and disassembly, and improves work efficiency.

[0053] Again, the two symmetrically arranged first connecting ear plates 42 and the two fifth connecting ear plates 63 located on the top of the fastening plate 61 above the main shaft 1 cooperate with each other to increase the contact area of ​​the connection, making the connection more stable. At the same time, the second serration structure on the first connecting ear plate 42 matches the first serration structure on the fifth connecting ear plate 63. When the two are fastened together by a bolt kit, the serration structures bite each other to increase the friction force, effectively preventing the connection parts from sliding relative to each other under stress, thereby improving the stability and reliability of the connection.

[0054] In addition, as the connecting part between the photovoltaic module 2 and the main shaft 1, the reliable connection design ensures the stability of the position and inclination of the photovoltaic module 2 in various environments, thereby improving the reliability and stability of the photovoltaic power generation system. The detachable connection facilitates adjustment and fixation when adjusting the inclination, thereby improving the adaptability and flexibility of the overall structure.

[0055] Finally, the second serration structure on the first connecting ear plate 42 matches the first serration structure on the fifth connecting ear plate 63 on the top of the upper fastening plate 61. This design can increase the friction and bite force of the connection part, so that when the two parts are connected together, the serration structures bite each other, effectively preventing the connection from loosening and slipping, and improving the stability and reliability of the connection.

[0056] The second connecting assembly 5 includes a second connecting plate 51 detachably mounted on the corresponding purlin 3, two second connecting ear plates 52 are symmetrically arranged at the middle position of the bottom of the second connecting plate 51, and two second connecting ear plates 52 are also symmetrically arranged near the two ends of the bottom of the second connecting plate 51.

[0057] The second connecting ear plates 52 are detachably connected to the oblique support frame 10 via the second bolt set 9 .

[0058] With such a design, firstly, the second connecting plate 51 is detachably connected to the purlin 3, and the second connecting ear plate 52 is detachably connected to the diagonal support frame 10 through the second bolt kit 9, so that it is convenient to handle each component before assembling it during installation, thereby reducing the difficulty and complexity of installation and improving the installation efficiency; it can be quickly separated during maintenance, replacement of components or adjustment of structure, thereby improving work efficiency.

[0059] Secondly, the second bolt set 9 ensures a tight connection and is not easy to loosen or fall off, thereby providing reliable support for the photovoltaic component 2; the symmetrically arranged multiple second connecting ear plates 52 share the load and increase the connection stability.

[0060] Furthermore, the detachable design allows the second connecting plate 51 or the second connecting ear plate 52 to be replaced according to different needs to adapt to purlins 3 or inclined support frames 10 of different sizes. Appropriate bolt and nut specifications and materials can also be selected according to the installation environment and stress conditions to ensure connection strength and durability.

[0061] Then, when a fault or damage occurs, it can be easily disassembled and replaced without large-scale disassembly of the entire tracking bracket, saving maintenance costs and time; the second connecting component 5 can be checked and repaired separately, improving the targetedness and efficiency of maintenance.

[0062] Finally, as the connecting part between the photovoltaic module 2 and the inclined support frame 10, the reliable connection design ensures the stability of the position and inclination of the photovoltaic module 2 in various environments, thereby improving the reliability and stability of the photovoltaic power generation system; the detachable connection with the inclined support frame 10 facilitates adjustment and fixation when adjusting the inclination, thereby improving the adaptability and flexibility of the overall structure.

[0063] The inclined support frame 10 includes a cross bar 101, and a plurality of third connecting ear plates 102 are arranged on the top of the cross bar 101, and the third connecting ear plates 102 correspond to the second connecting ear plates 52 one by one, and the third connecting ear plates 102 and the corresponding second connecting ear plates 52 are fastened together by a second bolt kit 9.

[0064] Two vertical rods 103 are symmetrically arranged at the bottom of the cross bar 101. An oblique rod 104 is connected to the side wall of the two vertical rods 103 facing away from each other and near the other end of the vertical rod 103 through a fifth bolt kit 105. The other end of the oblique rod 104 is fastened to the cross bar 101 through a sixth bolt kit 106.

[0065] One end of the vertical rod 103 away from the horizontal rod 101 is fixedly connected with a fourth connecting ear plate 107 , and the fourth connecting ear plate 107 is fastened together with the corresponding fifth connecting ear plate 63 by a third bolt set 11 .

[0066] A third sawtooth structure is provided on one side wall of the two fourth connecting ear plates 107 that are close to each other, and the third sawtooth structure matches the first sawtooth structure.

[0067] With this design, firstly, the top of the crossbar 101 is connected to the second connecting component 5 at multiple points to disperse the load, and the bottom triangular structure enhances stability, providing stable support for the photovoltaic component 2.

[0068] Secondly, the bolt kit connection makes it easy to connect and separate the components, which is not only convenient for transportation and assembly, but also improves installation efficiency; at the same time, when maintaining, replacing components or adjusting the structure, they can be quickly disassembled and handled separately, reducing maintenance costs.

[0069] Again, the inclined support frame 10 is an important connecting part. Its stable design and reliable connection ensure the stability of the position and inclination of the photovoltaic component 2, thereby improving the reliability of the power generation system. At the same time, its detachable connection with the second connecting component 5 and its own adjustability facilitate operations such as adjusting the inclination angle, thereby improving the adaptability and flexibility of the overall structure.

[0070] Finally, the fourth connecting ear plate 107 and the fifth connecting ear plate 63 are fastened by the third bolt set 11, and the third sawtooth structure matches the first sawtooth structure, which increases the tightness and firmness of the connection. The sawtooth structures bite each other, increase the friction, effectively prevent the connection parts from sliding relative to each other under stress, and ensure that the structure can remain stable under various working conditions.

[0071] During specific use, when it is necessary to adjust the north-south inclination angle of the photovoltaic component 2 to improve the power generation efficiency due to changes in lighting conditions, seasonal changes, etc., first use a tool to loosen the bolt kit between the first connecting component 4 and the first fastening component 6 and between the inclined support frame 10 and the second connecting component 5 and the second fastening component 7, but do not remove it completely. Then, before moving the second fastening component 7, the current position of the second fastening component 7 can be marked on the main shaft 1 so that it can be restored to the initial state when needed.

[0072] Subsequently, according to the size of the inclination angle to be adjusted, the moving direction and distance of the second fastening assembly 7 on the main shaft 1 are determined, and then the fourth bolt kit 62 in the second fastening assembly 7 is loosened, and the second fastening assembly 7 is moved to a predetermined position along the main shaft 1, and then the fourth bolt kit 62 in the second fastening assembly 7 is tightened, and one end of the inclined support frame 10 is connected to the second connecting assembly 5 through the second bolt kit 9, and the other end of the inclined support frame 10 is connected to the second fastening assembly 7 through the third bolt kit 11, and then the first connecting assembly 4 is reconnected to the first fastening assembly 6 through the first bolt kit 8 to ensure a firm connection. At this time, the inclination adjustment of the photovoltaic assembly 2 in the north-south direction is achieved.

[0073] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
