Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket adjusting device. Background Art

[0002] A photovoltaic panel mounting frame (also known as a photovoltaic bracket) is a structural system that supports photovoltaic modules, fixes their positions, and withstands environmental loads (such as wind, snow, and earthquake). Its design needs to consider strength, durability, installation convenience, and cost. In some large-scale ground power stations, a large number of photovoltaic panels are installed for power storage, and these photovoltaic panels need to be installed and fixed using brackets.

[0003] These large-scale ground power stations are mostly located in areas with sufficient sunlight, such as Xinjiang, Gansu, Qinghai, Ningxia, Inner Mongolia, etc. However, these areas are mostly plateau areas, and the ground is not as flat as that in plain areas. When installing photovoltaic panels, it is necessary to accurately adjust their tilt angles. If there is a deviation in the tilt angle of the photovoltaic panels, the sunlight reception efficiency will be reduced. A 5° inclination deviation may cause a 3% - 5% reduction in annual power generation. After the photovoltaic panel bracket structure is installed, it is affected by wind, sand, rain, and snow all year round. The structure used for fixing after the common bracket is adjusted is prone to looseness, which will affect the stability of the support for the photovoltaic panels, and even cause a change in the tilt angle of the photovoltaic panels, thus affecting the sunlight reception efficiency. Moreover, relying solely on the columns and diagonal braces at the four positions at the bottom of the bracket, the supporting effect is limited, and the frame for installing the photovoltaic panels has a large volume and weight. It is very difficult to adjust the angle of the photovoltaic panels manually. Therefore, this application proposes a photovoltaic bracket adjusting device. Summary of the Invention

When the two clamping rings are butted and closed, the two semi-circular limiting blocks are butted and together clamped in one of the limiting grooves on the outer wall of the column. Two second bolts are inserted through between the ends of the two clamping rings away from the collar.

[0010] Further, the diagonal bracing component includes a diagonal bracing rod, a second angle steel connecting plate and a first clamping hoop. The diagonal bracing rod is inclined between the diagonal beam and the sleeve. The second angle steel connecting plate is rotatably connected to the top end of the diagonal bracing rod, and the second angle steel connecting plate is connected to the bottom of the diagonal beam through a plurality of hexagonal bolts. The first clamping hoop is rotatably connected to the bottom end of the diagonal bracing rod, and the first clamping hoop is clamped and sleeved on the corresponding sleeve.

[0011] Further, the support mechanism includes a placing plate, a hydraulic cylinder and an anchor cone. The placing plate is arranged in a circular plate shape. A limiting ring is fixedly installed on the top of the placing plate. The bottom end of the hydraulic cylinder is inserted and tightened in the limiting ring. The top end of the hydraulic cylinder is rotatably connected to a third angle steel connecting plate.

[0015] Beneficial effects of the present invention: a. The overall stability of the bracket can be enhanced by installing the support mechanism and the reinforcement assembly. The anchor cone at the bottom of the storage plate in the support mechanism can be inserted into the ground, and then the threaded ring is twisted to squeeze the pressure ring and move it downward along the direction of the anchor cone. Under the squeezing action of the threaded ring, the pressure ring will be tightly pressed on the ground, and the hydraulic cylinder above the storage plate can connect and support the bottom plate in the photovoltaic panel outer frame, so as to support the center of the bottom of the photovoltaic panel outer frame. The two columns on the same side are connected by a cross bar, and the four reinforcement bars connected in the rotating groove of the side wall of the storage plate are respectively sleeved and clamped at the ends of the two cross bars through the second clamp, so that the reinforcement assembly will be supported on the two cross bar brackets in a cross shape, thereby further enhancing the stability of the four columns; b. When installing and adjusting the tilt angle of the photovoltaic panel frame, the hydraulic cylinder in the support mechanism is controlled so that the telescopic end of the hydraulic cylinder pushes the bottom plate, thereby adjusting the overall height of the photovoltaic panel frame, so that the sleeves connected to the four corners of the bottom of the photovoltaic panel frame are moved on the corresponding columns respectively, which can save some manpower and facilitate the angle adjustment of the photovoltaic panel frame, thereby improving the efficiency of the photovoltaic panel frame installation; c. After the angle of the photovoltaic panel frame is adjusted, the positioning assembly at the bottom of the sleeve can be used to stably fix the sleeve on the column. By flipping the two clamping rings in the positioning assembly, the two clamping rings are flipped around the corresponding second connecting piece and closed with the sleeve rings, so that the semicircular limit blocks on the inner walls of the two clamping rings can be engaged together in the limit grooves on the column, and then the two clamping rings can be connected together using the second bolt. The position of the sleeve can be stably fixed on the column through the engagement of the semicircular limit blocks and the limit grooves. As long as the second bolt does not detach from the two clamping rings, the positioning assembly will not loosen, thereby avoiding the deviation of the tilt angle of the photovoltaic panel caused by structural looseness.

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0018] Please refer to Figures 1-11, the present invention provides a technical solution: a photovoltaic bracket adjusting device, which includes four columns 1. The four columns 1 are distributed in pairs front and back. The heights of the two front columns 1 are less than those of the two rear columns 1. At the bottom ends of the four columns 1, embedded pipes 2 inserted into the ground are sleeved. At the top ends of the four columns 1, sleeves 3 are movably sleeved. At the top ends of the four sleeves 3, an inclined photovoltaic panel frame 4 is provided. A photovoltaic panel 5 is installed between the photovoltaic panel frames 4. Cross bars 71 are provided between the two columns 1 on the same side. A support mechanism 8 is provided below the photovoltaic panel frame 4. A reinforcement component 9 connected to the ends of the two cross bars 71 is provided on the support mechanism 8. Diagonal support components are provided at the bottoms of the four sleeves 3 and the bottom of the photovoltaic panel frame 4. Through the positioning component 32 at the bottom end of the sleeve 3, the position height of the sleeve 3 on the column 1 can be effectively fixed. The support mechanism 8 and the reinforcement component 9 can further improve the overall stability of the bracket. And by controlling the hydraulic cylinder 83, the photovoltaic panel frame 4 can be pushed to move up and down as a whole, which is convenient for workers to install and adjust the angle of the photovoltaic panel.

[0019] As Figure 1 and Figure 9 shown, the bottom ends of the four columns 1 are movably inserted into the top ends of the corresponding embedded pipes 2. A first bolt 21 is inserted through each of the four columns 1 and the corresponding embedded pipe 2. The bottom end of the embedded pipe 2 is set in a tapered shape. An outward expansion component is provided on the outer wall of each embedded pipe 2. The column 1 and the embedded pipe 2 can be connected together through the first bolt 21, and the outward expansion component on the outer wall of the embedded pipe 2 can enhance its stability when buried in concrete.

[0020] As Figure 1 and Figure 9As shown in the figure, the outward expansion component includes four first expansion plates 22, four second expansion plates 23, a fixed ring 25 and a lifting ring 26. Four first fixing members are evenly and fixedly installed at the lower position on the outer wall of the embedded pipe 2. The top ends of the four first expansion plates 22 are respectively rotatably sleeved on the corresponding first fixing members. A square-shaped first connecting member 24 is rotatably inserted at the top end of each of the four first expansion plates 22. The four second expansion plates 23 are respectively located at the top ends of the four first expansion plates 22, and the bottom ends of the four second expansion plates 23 are respectively rotatably sleeved on the corresponding first connecting members 24. The lifting ring 26 is movably sleeved on the embedded pipe 2. Four second fixing members are evenly and fixedly installed at the bottom of the lifting ring 26. The top ends of the four second expansion plates 23 are respectively rotatably sleeved on the corresponding second fixing members. The fixed ring 25 is fixedly installed on the embedded pipe 2 and is located below the lifting ring 26. Four notches are evenly formed in the fixed ring 25. The four second expansion plates 23 are respectively located in the notches corresponding to the positions on the fixed ring 25. Four studs 27 are evenly and fixedly installed on the top of the fixed ring 25. Nuts are threadedly sleeved on the four studs 27. Four through holes 28 are evenly formed in the lifting ring 26. The positions of the four through holes 28 are respectively aligned with the positions of the four studs 27 up and down. The lifting ring 26 can be lowered until the four through holes 28 are respectively sleeved on the four studs 27. When installing the embedded pipe 2, by lowering the lifting ring 26 to squeeze the second expansion plates 23 and the first expansion plates 22, the top end of the second expansion plate 23 will rotate around the second fixing member at the bottom of the lifting ring 26, the bottom end of the second expansion plate 23 and the top end of the first expansion plate 22 will rotate around the first connecting member 24 between them, and the bottom end of the first expansion plate 22 will rotate around the first fixing member, so that the second expansion plates 23 and the first expansion plates 22 expand outwards. When the lifting ring 26 moves to fit with the fixed ring 25, the four studs 27 on the fixed ring 25 will be respectively inserted into the four through holes 28 on the lifting ring 26, and then the nuts are screwed onto the studs 27 to squeeze the top of the lifting ring 26, and then the embedded pipe 2 can be concreted.

[0021] As Figures 2-5As shown in the figure, the outer frame 4 of the photovoltaic panel includes two inclined beams 41, two baffle plates 42, a bottom plate 43 and three support plates 45. The two inclined beams 41 are both L-shaped and symmetrically distributed left and right. The two baffle plates 42 are respectively installed between the two ends of the two inclined beams 41 through a plurality of hexagonal bolts. Three limit plates 44 are fixedly installed at the bottom of the two inclined beams 41. A plate groove is opened at the top end of each limit plate 44. The two ends of the three support plates 45 are respectively inserted into the plate grooves on the two relatively opposite limit plates 44. The top of the middle part of the three support plates 45 is flush with the top of the horizontal straight parts of the two inclined beams 41. In this way, the support plates 45 can cooperate with the two inclined beams 41 to effectively support the photovoltaic panel 5. The support plates 45 are installed in the plate grooves on the limit plates 44 through a plurality of hexagonal bolts. The two ends of the bottom plate 43 are respectively installed at the centers of the bottoms of the two baffle plates 42, and the top of the bottom plate 43 is in contact with the bottoms of the three support plates 45. The bottom plate 43 has the same inclination as the inclined beam 41 and is parallel to the inclined beam 41. The two ends of the bottom plate 43 are connected to the bottoms of the baffle plates 42 through a plurality of hexagonal bolts. The inclined beams 41, the baffle plates 42 and the support plates 45 are the main structural components of the outer frame 4 of the photovoltaic panel. Through the structure of the limit plates 44, the support plates 45 can be quickly installed between the two inclined beams 41, and the bottom plate 43 can support the bottoms of the three support plates 45 and the bottoms of the two baffle plates 42.

[0022] As Figure 6 , Figure 7 and Figure 8 shown in the figure, a first angle steel connecting plate 31 is rotatably installed at the top ends of the four sleeves 3. The four first angle steel connecting plates 31 are respectively fixedly installed at the bottoms of the two ends of the two inclined beams 41 through hexagonal bolts. Positioning components 32 are arranged at the bottom ends of the four sleeves 3. The positioning components 32 include a collar 321, two clamping rings 322 and two semi-circular limit blocks 324. The collar 321 is semi-circular. The upper half of the inner wall of the collar 321 is fixedly sleeved at the bottom end of the sleeve 3. The lower half of the inner wall of the collar 321 is movably sleeved on the column 1. The two clamping rings 322 are quarter-circular. Second connecting pieces 323 are fixedly installed at both ends of the collar 321. One ends of the two clamping rings 322 are respectively rotatably sleeved on the two second connecting pieces 323. A plurality of vertically arranged semi-circular limiting grooves 101 are evenly opened on the side wall of the column 1. The two semi-circular limit blocks 324 are respectively fixedly installed on the inner walls of the two clamping rings 322 far away from one end of the collar 321. When the two clamping rings 322 are butted and closed, the two semi-circular limit blocks 324 are butted and together clamped in one of the limiting grooves 101 on the outer wall of the column 1. Two second bolts 325 are inserted through between the two ends of the two clamping rings 322 far away from the collar 321.

[0023] After the angle adjustment of the photovoltaic panel outer frame 4 is completed, by flipping the two clamping rings 322 in the flipping positioning assembly 32, the two clamping rings 322 are flipped with the corresponding second connecting piece 323 as the center and closed with the collar 321. In this way, the semi-circular limiting blocks 324 on the inner walls of the two clamping rings 322 can be engaged in the limiting grooves 101 on the column 1 together. Then, use the second bolt 325 to connect the two clamping rings 322 together. Through the engagement of the semi-circular limiting block 324 and the limiting groove 101, the position of the sleeve 3 can be stably fixed on the column 1. As long as the second bolt 325 does not disengage from the two clamping rings 322, the positioning assembly 32 will not become loose, enabling the sleeve 3 to always stably support at the four corners at the bottom of the photovoltaic panel outer frame 4.

[0024] As Figure 3 and Figure 6 shown, the diagonal bracing assembly includes a diagonal bracing rod 61, a second angle steel connecting plate 62, and a first clamping member 63. The diagonal bracing rod 61 is inclined between the diagonal beam 41 and the sleeve 3. The second angle steel connecting plate 62 is rotatably connected to the top end of the diagonal bracing rod 61, and the second angle steel connecting plate 62 is connected to the bottom of the diagonal beam 41 through a plurality of hexagonal bolts. The first clamping member 63 is rotatably connected to the bottom end of the diagonal bracing rod 61, and the first clamping member 63 is clamped and sleeved on the corresponding sleeve 3. After adjusting the inclination angle of the photovoltaic panel outer frame 4, by rotating the diagonal bracing rod 61 to rotate with the second angle steel connecting plate 62 at the top end as the center, and then clamping and sleeving the first clamping member 63 at the bottom end of the diagonal bracing rod 61 on the corresponding sleeve 3. Through the diagonal bracing assembly, the stability of the support of the sleeve 3 on the photovoltaic panel outer frame 4 can be enhanced.

[0025] As Figure 2 , Figure 10 and Figure 11 shown, the support mechanism 8 includes a placement plate 81, a hydraulic cylinder 83, and an anchor cone 85. The placement plate 81 is set in a circular plate shape. A limiting ring 82 is fixedly installed on the top of the placement plate 81. The bottom end of the hydraulic cylinder 83 is inserted and tightened in the limiting ring 82. A third angle steel connecting plate 84 is rotatably connected to the top end of the hydraulic cylinder 83. The third angle steel connecting plate 84 is connected to the center of the bottom of the bottom plate 43 through a plurality of hexagonal nuts. The anchor cone 85 is fixedly installed at the center of the bottom of the placement plate 81. A pressure ring 86 is movably sleeved on the anchor cone 85, and a threaded ring 87 is threadedly sleeved on the anchor cone 85 above the pressure ring 86. Through the support mechanism 8, the stability of the support for the photovoltaic panel outer frame 4 can be enhanced. The anchor cone 85 at the bottom of the placement plate 81 in the support mechanism 8 can be inserted into the ground. Then, turn the threaded ring 87 to make it squeeze the pressure ring 86 to move downward along the direction of the anchor cone 85. Under the squeezing action of the threaded ring 87, the pressure ring 86 will tightly press on the ground, and the hydraulic cylinder 83 above the placement plate 81 can connect and support the bottom plate 43 in the photovoltaic panel outer frame 4, thereby being able to support the center of the bottom of the photovoltaic panel outer frame 4.

[0026] As Figure 2 , Figure 10 and Figure 11 shown, four rotating notches 88 are evenly formed on the side surface of the storage plate 81. Fixed shafts 89 are fixedly installed in the four rotating notches 88. The reinforcement assembly 9 includes four reinforcement rods 91 and four second clamp members 92. One ends of the four reinforcement rods 91 are respectively inserted into the four rotating notches 88 on the side wall of the storage plate 81 and rotatably sleeved on the corresponding fixed shafts 89. The four second clamp members 92 are respectively rotatably connected to one ends of the four reinforcement rods 91 away from the storage plate 81, and the four second clamp members 92 respectively clamp and sleeve on both ends of the two cross bars 71. The four reinforcement rods 91 connected in the rotating notches 88 on the side wall of the storage plate 81 are respectively sleeved and clamped on the ends of the two cross bars 71 through the second clamp members 92. In this way, the reinforcement assembly 9 will support in a cross shape between the two cross bars 71, thereby further enhancing the stability of the four columns 1.

[0027] As Figure 1 and Figure 2 shown, the second clamp member 92 includes two semi-circular clamping plates and a third connecting member. The two semi-circular clamping plates are butted and clamped on the cross bar 71. The third connecting member is rotatably inserted into the end of the reinforcement rod 91 and fixedly connected to the outer wall of one of the semi-circular clamping plates. Two fourth bolts are respectively inserted through between both ends of the two semi-circular clamping plates. The structure of the second clamp member 92 is the same as that of the first clamp member 63. By using the fourth bolts, the two semi-circular clamping plates can be butted and closed together, thereby fixedly clamping the second clamp member 92 on the cross bar 71. Similarly, the first clamp member 63 can also be fixedly clamped on the sleeve 3.

[0028] As Figure 6 and Figure 7 shown, screw grooves are formed at both ends of the two cross bars 71. Third bolts 72 are respectively inserted through the lower positions of the side walls of the four columns 1. The four third bolts 72 are respectively threadedly inserted into the screw grooves at the ends of the two cross bars 71. By using the third bolts 72, the two ends of the cross bar 71 can be respectively connected to the two columns 1 on the same side, so that the cross bar 71 horizontally supports between the two columns 1.

The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
