Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to a column combination and a photovoltaic tracking bracket. Background Art

[0002] In the sub-field of photovoltaics, namely agricultural light (i.e. the combination of photovoltaics and agriculture), the agricultural light tracking system meets the lighting needs of different crops through solar panels with different light transmittances or different panel layout designs, and flexibly creates an environment suitable for the growth of different crops. The agricultural light tracking system does not occupy additional land for power generation, nor does it change the nature of use. While generating photovoltaic power, it makes rational use of land resources, uses electricity nearby, reduces the loss caused by power transmission, and greatly improves the comprehensive utilization rate of energy. The organic combination of photovoltaics and agriculture can not only promote farmers' income, but also effectively solve the bottleneck problem of occupying a large amount of land for the development of photovoltaic power generation projects, and achieve a win-win situation of agricultural planting income and energy generation benefits. In the agricultural light tracking system, the agricultural light bracket is a very important component. The main function of the agricultural light bracket is to support and fix the solar panels in the agricultural light tracking system to ensure its normal operation and optimal performance.

[0003] At present, agricultural photovoltaic supports on the domestic market are all raised by prefabricated pipe piles (such as PHC pipe piles). Specifically, holes are pre-drilled on the ground, and then the prefabricated pipe piles are inserted into the pre-drilled holes. The bracket structure is then fixed on top of the prefabricated pipe piles to increase the height of the agricultural photovoltaic support. This design is more common in China, and prefabricated pipe piles are relatively easy to buy. However, such prefabricated pipe piles are not available abroad (such as Africa), and due to their heavy weight, prefabricated pipe piles are not convenient to transport abroad. In the absence of prefabricated pipe piles, foreign countries can only adopt the method of raising the pile columns, and the method of raising the pile columns is prone to buckling problems in the pile columns. In recent years, foreign countries have also paid more and more attention to the development of the agricultural photovoltaic field. How to achieve the height increase of agricultural photovoltaic supports abroad is an urgent problem to be solved. Utility Model Content

[0039] Please refer to Figures 1 to 20 As shown, the utility model first discloses a column assembly 100, which includes a plurality of pile columns 1 arranged in an array. The tops of two adjacent rows of two pile columns 1 are connected by a transverse beam 21, and the tops of two adjacent columns of two pile columns 1 are connected by a longitudinal beam 22, and the transverse beam 21 and the longitudinal beam 22 are vertically and horizontally connected to form a frame structure 2. The top of the frame structure 2 is used to set photovoltaic modules 200 to form an array arrangement of photovoltaic modules 200. The column assembly 100 of the utility model also includes a pile foundation support 3, which is arranged below each pile column 1, and the bottom of each pile column 1 is connected to the top of the corresponding pile foundation support 3 by a hinged manner. The column assembly 100 of the utility model includes a plurality of pile columns 1 arranged in an array and a frame structure 2 formed above the plurality of pile columns 1 for supporting a photovoltaic module 200. The bottom of each pile column 1 is connected to the top of a corresponding pile foundation bracket 3 by a hinged manner. Therefore, the utility model can be moved as a whole to a site where installation is required for assembly, and can be heightened by hinged pile foundation brackets 3 at the bottom of the pile column 1 according to actual needs. It does not rely on prefabricated pipe piles for heightening, avoids the buckling problem caused by heightening the pile column 1, is easy to operate, and reduces costs.

[0040] Please refer to Figure 8 , Figures 18 to 20 As shown, the column assembly 100 of the utility model also includes a top seat 10. The top seat 10 includes a top seat top plate 101 and a top seat side plate 102. The top of the top seat top plate 101 is fixedly connected to the longitudinal beam 22. The two top seat side plates 102 extend from both sides of the top seat top plate 101 in a direction away from the top seat top plate 101 and are fixed on the pile column 1. The top seat top plate 101 is connected between the tops of the two top seat side plates 102 along a first direction (longitudinal direction). Such a configuration facilitates the longitudinal beam 22 of the frame structure 2 to be fixed above the pile column 1 along the first direction in which the top seat top plate 101 extends through the top seat 10. In addition, a rectangular connecting plate 103 is provided in the space below the top seat top plate 101 between the two opposite inner sides of the two top seat side plates 102, and a triangular connecting plate 104 is provided on the two opposite outer sides of the two top seat side plates 102 and below the top seat top plate 101. The rectangular connecting plate 103 and the triangular connecting plate 104 both play a role in reinforcing the strength of the top seat 10 .

[0041] Please continue to refer to Figure 8 , Figures 14 to 19As shown, due to the presence of the rectangular connecting plate 103, in the space where the rectangular connecting plate 103 continues downward, the column assembly 100 of the utility model also includes a fixing frame 11. The two ends of the fixing frame 11 are respectively fixed on the inner sides of the two top seat side plates 102; preferably, the fixing frame 11 includes two symmetrically arranged up and down, and the end of the transverse beam 21 is first inserted into the space formed by the upper and lower two fixing frames 11 and then fixedly connected with the fixing frame 11. In this way, the end of the longitudinal beam 22 is fixed at a position above the top seat top plate 101, and the end of the transverse beam 21 is fixed at a position below the top seat top plate 101, which is convenient for fixing the transverse beam 21 and the longitudinal beam 22 of the frame structure 2 in a staggered manner above the pile column 1 through the fixing frame 11. That is, it is convenient for the transverse beam 21 and the longitudinal beam 22 to be connected vertically and horizontally to form the frame structure 2. The vertical and horizontal connection described here, due to the presence of the rectangular connecting plate 103, actually forms a certain height difference in the up and down directions, so the transverse beam 21 and the longitudinal beam 22 are still arranged in a staggered manner.

[0042] In a specific embodiment, a reinforcing support beam 20 is also connected between the bottom wall of the longitudinal beam 22 and the top seat side plate 102 / pile column 1. For example, the top seat side plate 102 is integrally formed with a first ear 1020, and the bottom wall of the longitudinal beam 22 is fixedly connected with a connecting seat 23, and the connecting seat 23 is integrally extended with a second ear 230. The opposite ends of the reinforcing support beam 20 are respectively fixedly connected to the first ear 1020 and the second ear 230 by a bolt 24. In other embodiments, a reinforcing support beam 20 can also be connected between the transverse beam 21 and the fixed frame 11 / pile column 1, and the specific connection method can also be fixed by similar bolts. It is self-evident that the role of the reinforcing support beam 20 is to support and strengthen the frame structure 2.

[0043] The above describes the connection method between the top of each pile column 1 and the frame structure 2; the following focuses on how the bottom of each pile column 1 is connected to the top of the corresponding pile foundation support 3 in a hinged manner.

[0044] Please refer to Fig. 9 and Fig.10 As shown, the pile foundation support 3 includes a pile foundation 30 fixed on the ground and a pile foundation column 31 with adjustable height, and the pile foundation column 31 is detachably mounted on the pile foundation 30. Therefore, the utility model can perform different degrees of heightening at the bottom of the pile column 1 according to actual needs, and only needs to replace the pile foundation columns 31 of different heights. The utility model does not rely on prefabricated pipe piles for heightening, and also avoids the buckling problem caused by heightening the pile column 1.

[0045] In a specific embodiment, the pile column 1 and the pile foundation column 31 are both metal structures. Preferably, the pile column 1 and the pile foundation column 31 are both steel "I" shaped structures, for example: the pile foundation column 31 includes a base plate 310 and a pair of side plates 311 integrally formed at both ends of the base plate 310, which can effectively ensure the structural strength of the product; the pile column 1 also has a structure basically similar to the pile foundation column 31, but usually has a greater height; of course, the height of the pile foundation column 31 is not the only determined height in the figure, and can be adjusted as needed, that is, as mentioned above, only by replacing pile foundation columns 31 of different heights, the bottom of the pile column 1 can be heightened to different degrees by replacing pile foundation columns 31 of different heights. The pile column 1 and the pile foundation column 31 are both metal structures, which are easier to transport and install than prefabricated pipe piles (such as PHC pipe piles) in the prior art.

[0046] Please refer to Figures 9 to 12 As shown, the column assembly 100 of the utility model further includes a first shaft member 4, a hinge plate 5 and a hinge seat 6. The hinge plate 5 is connected to the pile column 1 and extends downward from the bottom of the pile column 1. The hinge seat 6 is clamped on the top of the pile foundation bracket 3 and has a support plate portion 611 extending upward. The hinge plates 5 are two and a clamping space of the support plate portion 611 is formed between the two hinge plates 5. The first shaft member 4 passes through the hinge plate 5 and the support plate portion 611 to form a hinge. The upper part of the hinge plate 5 is fixed to the opposite sides of the pile column 1. Specifically, the upper part of the hinge plate 5 is fixed to the opposite sides of the pile column 1 by bolts; in other embodiments, the upper part of the hinge plate 5 can also be fixed to the opposite sides of the pile column 1 by welding. Through holes are provided on the hinge plate 5 and the support plate portion 611. In this way, the first shaft member 4 of the utility model can pass through the through holes on the hinge plate 5 and the through holes on the support plate portion 611 to form a hinge. Of course, in other embodiments, the hinge plate 5 can be provided as one, and can also be hinged with the hinge seat 6 , but the hinge effect is not as good as that of two hinge plates 5 sandwiching the support plate portion 611 .

[0047] Please refer to Fig. 9 and Fig.10 As shown, the articulated seat 6 includes an upper seat body 61 and a lower seat body 62. The upper seat body 61 includes a horizontal bottom plate 610, and a support plate portion 611 protrudes upward from the horizontal bottom plate 610. The lower seat body 62 includes a horizontal top plate 620 and a pair of side arm portions 621, and the side arm portions 621 extend downward from opposite sides of the horizontal top plate 620. The support plate portion 611 and the pair of side arm portions 621 are extended in opposite directions, and the horizontal bottom plate 610 is fixed to the horizontal top plate 620, so that the upper seat body 61 and the lower seat body 62 are connected as a whole. Specifically, the horizontal bottom plate 610 and the horizontal top plate 620 are fixed by welding. In other embodiments, the horizontal bottom plate 610 and the horizontal top plate 620 can also be fixed by bolts or the like.

[0048] Please refer to Figures 9 to 13 As shown, the column assembly 100 of the utility model further includes a second shaft member 7. The pile foundation column 31 includes a base plate 310 and a pair of side plates 311 integrally formed at both ends of the base plate 310. The side arm portion 621 is closely arranged with the side plates 311 in a one-to-one correspondence, and the horizontal top plate 620 is laterally arranged across the top of the base plate 310. The side arm portion 621 is provided with a first through hole 6210, and the side plate 311 is provided with a second through hole 3110. The second shaft member 7 is passed through the first through hole 6210 and the second through hole 3110 to connect the hinge seat 6 to the pile foundation column 31. The second shaft member 7 has the same basic structure as the first shaft member 4, but has different functions (to be described in detail later).

[0049] Please refer to Fig.10 As shown, each side plate 311 includes a plurality of second through holes 3110 divided into two rows, and each row of second through holes 3110 is arranged at intervals in the vertical direction of the pile foundation column 31. The purpose of the vertical intervals is mainly to adjust the height.

[0050] Please continue to refer to Fig.10 As shown, the first through hole 6210 includes a circular through hole 62101, and the circular through hole 62101 corresponds to one of the rows of the second through holes 3110. There are at least two second shaft members 7, and one of the second shaft members 7 passes through one of the circular through hole 62101 and one of the rows of the second through holes 3110 to adjust the installation height of the pile column 1 relative to the pile foundation column 31. And / or, the first through hole 6210 includes an arcuate through hole 62102, and the arcuate through hole 62102 corresponds to another row of the second through holes 3110. There are at least two second shaft members 7, and another second shaft member 7 passes through the arcuate through hole 62102 and one of the rows of the second through holes 3110 to adjust the installation angle of the pile column 1 relative to the pile foundation column 31. The change of the installation angle means the change of the slope.

[0051] It can be understood that the through holes on the hinge plate 5 and the support plate portion 611 through which the first shaft member 4 passes are fixed, not multiple; while the first through hole 6210 on the side arm portion 621 of the lower seat body 62 through which the second shaft member 7 passes is fixed, and the second through hole 3110 on the side plate 311 of the pile foundation column 31 is not fixed, and one can be selected from multiple second through holes 3110. Therefore, the main function of the first shaft member 4 is to be used for hinge connection (it can rotate while connected), and the main function of the second shaft member 7 is to connect first, and on the basis of connection, it is also used to adjust the height or slope. Although the second shaft member 7 also rotates a little during the slope adjustment process, it is different from the rotation of the first shaft member 4. The difference is that the through hole through which the first shaft member 4 passes is a circular through hole, so it can theoretically rotate 360 ​​degrees; the first through hole 6210 through which the second shaft member 7 passes includes an arc-shaped through hole 62102, so the angle at which the second shaft member 7 can rotate will be limited by the arc of the arc-shaped through hole 62102. That is, generally speaking, the angle at which the first shaft member 4 can rotate is greater than the angle at which the second shaft member 7 can rotate.

[0052] Please refer to Figures 1 to 20 As shown, the utility model also discloses a photovoltaic tracking bracket 300, which includes a first main shaft 201, a second main shaft 202, a bearing assembly 205, a driving device 204 and the column assembly 100 as described above. The driving device 204 is installed on the pile column 1 and drives the first main shaft 201; the first main shaft 201 and the second main shaft 202 are arranged in parallel, and the first main shaft 201 and the second main shaft 202 are installed on the transverse beam 21 or the longitudinal beam 22 through the bearing assembly 205. For details, please refer to Figure 5 The bearing assembly 205 includes a bearing 2051 covered outside the first main shaft 201 / second main shaft 202 and a bearing seat 2052 covered outside the bearing 2051. The bearing seat 2052 is fixedly mounted on the transverse beam 21 or the longitudinal beam 22. Due to the rolling connection effect of the bearing 2051 between the first main shaft 201 / second main shaft 20 and the bearing seat 2052, the first main shaft 201 / second main shaft 20 can be driven to rotate relative to the transverse beam 21 / longitudinal beam 22.

[0053] Since the first main shaft 201 and the second main shaft 202 are arranged in parallel, the “first main shaft 201 / the second main shaft 20 can be driven to rotate relative to the transverse beam 21 / the longitudinal beam 22” means that the first main shaft 201 and the second main shaft 20 either rotate relative to the transverse beam 21 or rotate relative to the longitudinal beam 22, and there is no situation where the first main shaft 201 and the second main shaft 20 rotate alternately.

[0054] Please refer to Figures 1 to 7 as well as Figures 14 to 16As shown, the photovoltaic tracking bracket 300 of the utility model further includes a linkage shaft 203, which connects the first main shaft 201 and the second main shaft 202. The first main shaft 201 is located above each row of transverse beams 21 or above each column of longitudinal beams 22 in the vertical direction, and is used to install a row or a column of photovoltaic modules 200. The second main shaft 202 is arranged in parallel between two adjacent rows of transverse beams 21 or between two adjacent columns of longitudinal beams 22, and is used to add a row or a column of driven photovoltaic modules 200'. The driving device 204 actively drives a row or a column of photovoltaic modules 200 and drives the added row or column of driven photovoltaic modules 200' through the linkage shaft 203. Therefore, the photovoltaic tracking bracket 300 of the utility model can install as many photovoltaic modules 200 / 200' as possible in a limited space.

[0055] For example: if the lateral extension direction along the transverse beam 21 is calculated as rows, there are four rows of pile columns 1 in the tracking bracket 300 of the utility model and four rows of first main shafts 201. The driving device 204 on each pile column 1 corresponds to driving a row of photovoltaic components 200 fixed by the first main shaft 201; the second main shaft 202 is additionally added between two adjacent first main shafts 201, and there are no corresponding pile columns 1 and transverse beams 21 below it. Therefore, the photovoltaic component 200' fixed by the second main shaft 202 has no direct driving force and can only rely on the linkage shaft 203 to drive it to rotate to track sunlight. Such an arrangement ensures that the driving device 204 actively drives a row or a column of photovoltaic components 200 and drives the added row or column of driven photovoltaic components 200' through the linkage shaft 203, thereby increasing the density of photovoltaic components and making rational use of space; since the driving device 204 on a row of pile columns 1 actively drives a row or a column of photovoltaic components 200 and drives a row or a driven photovoltaic component 200', the driving device 204 will not drive too many photovoltaic components and cause a situation where it cannot be driven.

[0056] Since the first main axis 201 and the second main axis 202 are arranged in parallel, the “one row or one column” mentioned here means that the photovoltaic components 200 and the photovoltaic components 200 ′ are either arranged in rows or in columns, and there is no staggered arrangement of some in rows and some in columns.

[0057] The photovoltaic tracking bracket 300 of the present invention, wherein the column combination 100 includes a plurality of pile columns 1 arranged in an array, and a frame structure 2 for supporting the photovoltaic module 200 is formed above the plurality of pile columns 1, and the bottom of each pile column 1 is connected to the top of the corresponding pile foundation bracket 3 by a hinged manner. Therefore, the column combination 100 of the photovoltaic tracking bracket 300 of the present invention can be conveniently moved to the installation site for assembly in the form of a plurality of pile columns and a plurality of beams, and can be heightened by hingedly connecting the pile foundation bracket 3 at the bottom of the pile column 1 according to actual needs, which does not rely on prefabricated pipe piles for heightening, avoids the buckling problem caused by heightening the pile column 1, is easy to operate, and reduces costs.

[0058] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
