Description

Technical Field

[0001] The present invention relates to the technical field of installation bases, and specifically relates to a photovoltaic installation base. Background Art

[0002] Photovoltaic is a technology that uses the photovoltaic effect of semiconductor materials to directly convert solar energy into electrical energy. It is a core component in the field of renewable energy and is widely used in the global energy transition. Usually, photovoltaic panels receive sunlight and form an electric current. When installing photovoltaic panels, a base is usually set at the bottom to carry and install the photovoltaic panels and lift them off the ground, preventing the bottom of the photovoltaic panels from being affected by moisture and corrosion, which may affect their service life.

[0003] When installing traditional photovoltaic panels, the columns and crossbeams are usually assembled first, and the photovoltaic panels are fixed to the crossbeams using clamps. When it is necessary to adjust the tilt angle and height of the photovoltaic panels according to requirements such as terrain and lighting angle, since the column consists of two layers of steel pipes, inner and outer, and they are fixed by bolts, the height of the column can be adjusted by removing the bolts and staggering the inner and outer steel pipes up and down. Also, the tilt angle of the photovoltaic panels can be adjusted by changing the height difference between the front and rear columns. However, due to the constantly changing lighting angle in different seasons, in order to enable the photovoltaic panels to obtain the best lighting conditions, it is necessary for the operator to repeatedly remove the bolts and adjust the height of the columns, and then change the tilt angle of the photovoltaic panels, resulting in a cumbersome operation process and low installation or adjustment efficiency. When fixing the photovoltaic panels, the photovoltaic panels are usually laid flat on the crossbeams one by one, and bolts are used to fix the clamps at the edges of the photovoltaic panels, and the clamps are pressed against the edges of the photovoltaic panels. Therefore, it is necessary to drill multiple holes on the crossbeams to fix the bolts first. However, since the shapes and sizes of the photovoltaic panels are different, when installing photovoltaic panels of different sizes, it is necessary to re-drill holes on the crossbeams or adjust the position of the crossbeams, and at the same time, it is necessary to continuously adjust the positions of multiple clamps according to the size of the photovoltaic panels, resulting in a cumbersome operation process and poor flexibility. When using clamps to fix the photovoltaic panels, the clamps are usually fixed to the crossbeams using screws at the four corners of the photovoltaic panels in sequence. However, when a certain photovoltaic panel is damaged and needs to be disassembled, replaced, or repaired, it is necessary to remove the clamps at the four corners of the photovoltaic panel in sequence, and thus it is necessary to repeatedly remove and fix the screws, resulting in low operation efficiency.

Specific embodiments

[0021] 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 specific embodiments.

[0022] As Figures 2 - 4 and Figure 10As shown in the figure, a photovoltaic installation base according to the present invention includes a cement pier 1, a height adjustment structure 2 installed on the cement pier 1, an angle adjustment structure 3 fitted on the height adjustment structure 2, a load-bearing structure 4 connected to the angle adjustment structure 3, a shock absorption structure 5 arranged inside the angle adjustment structure 3, and a clamping structure 6 installed on the load-bearing structure 4. The clamping structure 6 includes a plurality of load-bearing frames 601 and second guide rods 602 fixedly connected to the load-bearing frames 601. A plurality of load-bearing frames 601 are installed on both of the first load-bearing beams 401 located on the side. The load-bearing frames 601 and the first load-bearing beams 401 are fixedly connected by second bolts 603. A guide plate 604 is slidably connected between two pairs of the second guide rods 602 located on both sides. The guide plate 604 is slidably connected with the load-bearing frames 601. A tension spring 605 is fixedly connected between the bottom surface of the guide plate 604 and the load-bearing frames 601. A first clamping plate 607 is slidably connected to each end of the guide plate 604. A second spring 608 is fixedly connected between the first clamping plate 607 and the end of the guide plate 604. Three second clamping plates 609 are slidably connected to the central position of the guide plate 604. A second knob 610 is threadedly connected to the bottom of the second clamping plate 609. The top of the second knob 610 abuts against the bottom surface of the guide plate 604. A first knob 606 is threadedly connected to one of the load-bearing frames 601. The first knob 606 is slidably connected with the inner wall of the guide plate 604. The end of the first knob 606 is in a "T" shape. The end of the first knob 606 abuts against the upper surface of the guide plate 604. A plurality of photovoltaic panels 7 are abutted between the three first load-bearing beams 401. Both the first clamping plate 607 and the second clamping plate 609 abut against the upper surface of the photovoltaic panel 7;Install multiple photovoltaic panels 7 on the base in sequence. First, only rotate the second knob 610 at the bottom of the second clamping plate 609 so that the top end of the second knob 610 no longer touches the bottom surface of the guide plate 604. At the same time, lift two adjacent guide plates 604 upward. At this time, adjust the positions of the three second clamping plates 609 according to the size of the photovoltaic panel 7 so that the three second clamping plates 609 cooperate with each other to clamp the two photovoltaic panels 7 at the central position. Then tighten the second knob 610. At this time, the position of the second clamping plate 609 can be quickly adjusted to facilitate adapting to photovoltaic panels 7 of different widths. Then, sequentially insert the photovoltaic panels 7 installed on both sides between the first clamping plate 607 and the second clamping plate 609. Since the second spring 608 is fixedly connected between the end of the first clamping plate 607 and the guide plate 604, the second spring 608 drives the first clamping plates 607 on both sides to slide towards the central position of the base under the reset action, so as to cooperate with the adjacent second clamping plates 609 to clamp and fix the sides of the photovoltaic panel 7. Then, simultaneously loosen two adjacent guide plates 604. Then, the guide plates 604 slide downward along the second guide rod 602 under the reset action of the tension spring 605. At the same time, the guide plates 604 drive the first clamping plates 607 on both sides and the second clamping plate 609 at the center to slide downward until the ends of the first clamping plate 607 and the second clamping plate 609 touch the upper surface of the photovoltaic panel 7. At this time, the preliminary fixation of four photovoltaic panels 7 in the same row is completed. Then, sequentially rotate the first knobs 606 on two adjacent load-bearing frames 601. Since the first knob 606 is threadedly connected to the load-bearing frame 601, the first knob 606 will move downward until the end of the first knob 606 touches the upper surface of the guide plate 604. At this time, the first knob 606 presses the guide plate 604 downward, so that the guide plate 604 drives the first clamping plate 607 and the second clamping plate 609 to move downward and press the photovoltaic panel 7, thereby further fixing the photovoltaic panel 7 and preventing the photovoltaic panel 7 from falling off due to factors such as vibration or strong wind, improving the stability.;

[0023] Specifically, such as Figures 1 - 4 、 Figure 6 and Figures 11 - 12As shown in the figure, the load-bearing structure 4 includes a first load-bearing beam 401 and a plurality of mounting holes 402 formed on the side surface of the load-bearing beam 401. Three first load-bearing beams 401 are mounted on the angle-adjusting structure 3. The mounting holes 402 are fitted with a clamping structure 6. A plurality of second load-bearing beams 403 are fixedly connected between the three first load-bearing beams 401, and the plurality of second load-bearing beams 403 are arranged at equal intervals. Since the load-bearing frames 601 on both sides are installed at the mounting holes 402 on the first load-bearing beam 401 by using the second bolts 603, the firmness is strong. At the same time, since a plurality of mounting holes 402 are equidistantly formed on the first load-bearing beam 401, it is convenient to flexibly adjust the mounting position of the load-bearing frame 601. When fixing photovoltaic panels 7 of different lengths, by adjusting the positions of the first clamping plate 607 and the second clamping plate 609, the stress points of the photovoltaic panels 7 can be flexibly adjusted, the firmness is improved, and at the same time, the problem that the first clamping plate 607 and the second clamping plate 609 are suspended due to the small length of the photovoltaic panel 7 is avoided. The flexibility is strong. And since a plurality of second load-bearing beams 403 are connected to the bottom of the three first load-bearing beams 401, the overall load-bearing capacity is enhanced and the firmness is improved.

[0024] Specifically, as Figures 1 - 12As shown in the figure, the height adjustment structure 2 includes a U-shaped bolt 201 and a first mounting sleeve 202 connected to the U-shaped bolt 201. The U-shaped bolts 201 are fixedly connected to the central positions of the six cement piers 1. Among them, mounting seats 211 are fixedly connected to the three U-shaped bolts 201 located on the front side. The first mounting sleeve 202 is rotatably connected to the mounting seat 211. The three U-shaped bolts 201 located on the rear side are fixedly connected with second mounting sleeves 204. The bottom surface of the second mounting sleeve 204 abuts against the cement pier 1. A first sliding column 203 is slidably connected inside the first mounting sleeve 202, and a second sliding column 205 is slidably connected inside the second mounting sleeve 204. First sliding grooves 206 are provided on the first mounting sleeve 202 and the second mounting sleeve 204 located at the central position. Second sliding grooves 207 are provided on the adjacent first sliding column 203 and second sliding column 205. First hydraulic rods 209 are fixedly connected to the first mounting sleeve 202 and the second mounting sleeve 204 located at the central position. The telescopic ends of the first hydraulic rods 209 are fixedly connected with drive plates 208. The two drive plates 208 are slidably connected between the first mounting sleeve 202 and the second mounting sleeve 204 respectively. A drive rod 210 is fixedly connected to the drive plate 208. The drive rod 210 is slidably connected with the adjacent first sliding groove 206. The drive rod 210 abuts against the top end of the second sliding groove 207. An angle adjustment structure 3 is provided on the drive rod 210 close to the first mounting sleeve 202. The first mounting sleeve 202 and the second mounting sleeve 204 are both in a "T" shape. The lengths of the second mounting sleeve 204 and the second sliding column 205 are both greater than the lengths of the first mounting sleeve 202 and the first sliding column 203. If the power generation efficiency of the photovoltaic panel 7 is affected by factors such as buildings, mountains or trees, etc., it is necessary to adjust the overall height of the photovoltaic panel 7. Since the first hydraulic rods 209 are installed on the first mounting sleeve 202 and the second mounting sleeve 204 located at the central position, the telescopic ends of the two first hydraulic rods 209 extend outwards simultaneously and drive the drive plates 208 to slide upwards. The two drive plates 208 drive the two drive rods 210 to slide upwards along the adjacent first sliding grooves 206 respectively. Since the drive rod 210 is at the topmost position of the second sliding groove 207 at this time, when the drive rod 210 slides upwards along the first sliding groove 206, the two drive rods 210 drive the first sliding column 203 and the second sliding column 205 to move upwards respectively. At the same time, the first sliding columns 203 and the second sliding columns 205 located on both sides slide upwards along the inner walls of the first mounting sleeve 202 and the second mounting sleeve 204 respectively. At this time, the three first sliding columns 203 located on the front side cooperate with the three second sliding columns 205 located on the rear side to lift the multiple photovoltaic panels 7 upwards as a whole by a certain distance until the obstacles in the surrounding environment no longer block the light on the photovoltaic panel 7, which is beneficial to improving the power generation efficiency of the photovoltaic panel 7 and has strong flexibility.

[0025] Specifically, asFigure 1 , Figures 3 - 5 , Figure 8 , Figure 9 , Figure 11 and Figure 12As shown in the figure, the angle adjustment structure 3 includes a support plate 301 and a second hydraulic rod 302 fixedly connected to the support plate 301. A support plate 301 is fixedly connected to the driving rod 210 near the first mounting sleeve 202. The support plate 301 is slidably connected to the outer wall of the first mounting sleeve 202. The telescopic end of the second hydraulic rod 302 is fixedly connected to a connecting plate 303. The connecting plate 303 and the first sliding column 203 are fixedly connected by a first bolt 305. The top of the first sliding column 203 is engaged with a docking head 304. A rotating shaft 306 is provided at the top of the docking head 304. An installation frame 307 is rotatably connected to the rotating shaft 306. The docking head 304 has a "convex" structure. The first bolt 305 passes through a groove formed at the bottom of the docking head 304. A first load-bearing beam 401 is fixedly connected between the front and rear installation frames 307; since factors such as latitude, longitude, season, and solar altitude angle in different regions will affect the angle and duration of sunlight received by the photovoltaic panel 7, it is necessary to adjust the tilt angle of the photovoltaic panel 7 in different seasons. The second hydraulic rod 302 provided on the first mounting sleeve 202 at the center of the base drives the connecting plate 303 to move upward. Since the connecting plate 303 is connected to the top of the first sliding column 203 by the first bolt 305, the second hydraulic rod 302 drives the first sliding column 203 to slide upward. And in the initial state, due to the action of gravity on the first sliding column 203, the top of the second chute 207 always contacts the driving rod 210. The setting of the second chute 207 can prevent the driving rod 210 from blocking the upward movement of the first sliding column 203. The first sliding column 203 drives the docking head 304, the installation frame 307, and the first load-bearing beam 401 at the top to move upward. And since the positions of the three second sliding columns 205 at the rear remain unchanged at this time, and the first sliding column 203 at the central position drives the other two first sliding columns 203 on both sides to move upward, effectively lifting the front part of the photovoltaic panel 7 upward. At the same time, since the installation frame 307 below the photovoltaic panel 7 is rotatably connected to the docking head 304 through the rotating shaft 306, and since the bottom of the first mounting sleeve 202 is rotatably connected to the mounting seat 211, it does not block the rotation of the photovoltaic panel 7, making the angle between the photovoltaic panel 7 and the horizontal plane gradually smaller, and can effectively adjust the tilt angle of the photovoltaic panel 7. The operation is simple. When both the height and the tilt angle need to be adjusted, since the support plate 301 at the bottom of the second hydraulic rod 302 is connected to the driving plate 208 through the driving rod 210, during the process of the first hydraulic rod 209 driving the first sliding column 203 to move upward, it can drive the second hydraulic rod 302 to move upward at the same time, not only increasing the adjustment range of the tilt angle, but also when the front and rear two first hydraulic rods 209 lift the photovoltaic panel 7 as a whole to the highest position, it can still adjust the tilt angle of the photovoltaic panel 7 through the second hydraulic rod 302, with strong practicability. And the U-shaped bolts 201 are buried in the central position in advance when pouring the cement pier 1, which is convenient for subsequent assembly of the base and improves the installation efficiency.

[0026] Specifically, as Figure 4 , Figure 9 and Figure 12 shown, the shock-absorbing structure 5 includes a first guide rod 501 and a carriage 502 slidably connected to the first guide rod 501. Two first guide rods 501 are fixedly connected inside the docking head 304. A first spring 503 is fixedly connected between the bottom surface of the carriage 502 and the docking head 304. A rotating shaft 306 is fixedly connected to the carriage 502. The top of the docking head 304 is engaged with a top cover 504. The carriage 502 is in a "U" - shaped structure. Since the rotating shaft 306 at the top of the docking head 304 is connected to the carriage 502, and the carriage 502 can slide up and down along the first guide rod 501. Then when encountering strong wind or vibration, the carriage 502 can drive the rotating shaft 306 and the mounting bracket 307 to move up and down, and at the same time compress the first spring 503. The mounting bracket 307 drives the first load-bearing beam 401 and the photovoltaic panel 7 to move up and down. At this time, the first spring 503 plays a shock-absorbing effect, avoiding the problem that when the photovoltaic panel 7 vibrates due to factors such as strong wind and earthquake, the connecting components of the photovoltaic panel 7 such as bolts and nuts become loose because the position of the photovoltaic panel 7 is fixed. And the top of the docking head 304 is engaged with a top cover 504, which plays a waterproof and dust-proof effect.

[0027] When the present invention is in use, multiple photovoltaic panels 7 are sequentially installed on the base. First, only need to rotate the second knob 610 at the bottom of the second clamping plate 609 so that the top of the second knob 610 no longer abuts against the bottom surface of the guide plate 604, and at the same time lift two adjacent guide plates 604 upward. At this time, then adjust the positions of the three second clamping plates 609 according to the size of the photovoltaic panel 7, so that the three second clamping plates 609 cooperate with each other to clamp the two photovoltaic panels 7 at the central position. Then tighten the second knob 610. At this time, the position of the second clamping plate 609 can be quickly adjusted to facilitate adapting to photovoltaic panels 7 of different widths. Then, sequentially insert the photovoltaic panels 7 installed on both sides between the first clamping plate 607 and the second clamping plate 609. Since a second spring 608 is fixedly connected between the end of the first clamping plate 607 and the guide plate 604, the two first clamping plates 607 on both sides are driven to slide towards the central position of the base under the reset action of the second spring 608, so as to cooperate with the adjacent second clamping plates 609 to clamp and fix the side surfaces of the photovoltaic panels 7. Then, simultaneously loosen two adjacent guide plates 604. Then, the guide plates 604 slide downward along the second guide rod 602 under the reset action of the tension spring 605. At the same time, the guide plates 604 drive the two first clamping plates 607 on both sides and the second clamping plate 609 at the center to slide downward until the ends of the first clamping plate 607 and the second clamping plate 609 abut against the upper surface of the photovoltaic panel 7. At this time, the preliminary fixation of four photovoltaic panels 7 in the same row is completed. Then, sequentially rotate the first knobs 606 on two adjacent load-bearing frames 601. And since the first knob 606 is threadedly connected to the load-bearing frame 601, the first knob 606 will move downward until the end of the first knob 606 abuts against the upper surface of the guide plate 604. At this time, the first knob 606 presses the guide plate 604 downward, so that the guide plate 604 drives the first clamping plate 607 and the second clamping plate 609 to move downward and press the photovoltaic panel 7, thereby further fixing the photovoltaic panel 7, avoiding the photovoltaic panel 7 from falling off under factors such as vibration or strong wind, improving the stability. And since the two load-bearing frames 601 on both sides are installed at the installation holes 402 on the first load-bearing beam 401 by using the second bolts 603, the firmness is strong. At the same time, since a plurality of installation holes 402 are equidistantly arranged on the first load-bearing beam 401, it is convenient to flexibly adjust the installation position of the load-bearing frame 601. When it is necessary to fix photovoltaic panels 7 of different lengths, by adjusting the positions of the first clamping plate 607 and the second clamping plate 609, the stress points of the photovoltaic panel 7 can be flexibly adjusted, improving the firmness, and at the same time avoiding the problem that the first clamping plate 607 and the second clamping plate 609 are suspended due to the small length of the photovoltaic panel 7, with strong flexibility. And since a plurality of second load-bearing beams 403 are connected to the bottom of the three first load-bearing beams 401, the overall load-bearing capacity is enhanced and the firmness is improved; When the power generation efficiency of the photovoltaic panel 7 is affected by factors such as buildings, mountains or trees, etc., it is necessary to adjust the overall height of the photovoltaic panel 7. Since the first hydraulic rods 209 are installed on both the first mounting sleeve 202 and the second mounting sleeve 204 located at the central position, the telescopic ends of the two first hydraulic rods 209 extend outward simultaneously and drive the driving plate 208 to slide upward. The two driving plates 208 respectively drive the two driving rods 210 to slide upward along the adjacent first sliding grooves 206. Since the driving rods 210 are at the topmost position of the second sliding grooves 207 at this time, during the process of the driving rods 210 sliding upward along the first sliding grooves 206, the two driving rods 210 respectively drive the first sliding column 203 and the second sliding column 205 to move upward. At the same time, the first sliding column 203 and the second sliding column 205 located on both sides slide upward along the inner walls of the first mounting sleeve 202 and the second mounting sleeve 204 respectively. At this time, the three first sliding columns 203 located on the front side cooperate with the three second sliding columns 205 located on the rear side to lift the plurality of photovoltaic panels 7 as a whole upward by a certain distance until the obstacles in the surrounding environment no longer block the light on the photovoltaic panels 7, which is beneficial to improving the power generation efficiency of the photovoltaic panels 7 and has strong flexibility; Since factors such as latitude, longitude, seasons, and solar altitude angles in different regions will affect the angle and duration of sunlight received by the photovoltaic panel 7, it is necessary to adjust the tilt angle of the photovoltaic panel 7 in different seasons. The second hydraulic rod 302 provided on the first mounting sleeve 202 at the center of the base drives the connecting plate 303 to move upward. Since the connecting plate 303 is connected to the top of the first sliding column 203 through the first bolt 305, the second hydraulic rod 302 drives the first sliding column 203 to slide upward. And in the initial state, due to the action of gravity on the first sliding column 203, the top of the second sliding groove 207 is always in contact with the driving rod 210. The setting of the second sliding groove 207 can prevent the driving rod 210 from blocking the upward movement of the first sliding column 203. The first sliding column 203 drives the docking head 304, the mounting bracket 307, and the first load-bearing beam 401 at the top to move upward. And since the positions of the three second sliding columns 205 at the rear remain unchanged at this time, and the first sliding column 203 at the central position drives the other two first sliding columns 203 on both sides to move upward, effectively lifting the front part of the photovoltaic panel 7 upward. At the same time, since the mounting bracket 307 below the photovoltaic panel 7 is rotatably connected to the docking head 304 through the rotating shaft 306, and since the bottom of the first mounting sleeve 202 is rotatably connected to the mounting seat 211, it does not block the rotation of the photovoltaic panel 7, making the angle between the photovoltaic panel 7 and the horizontal plane gradually smaller, and can effectively adjust the tilt angle of the photovoltaic panel 7, with simple operation. When both height adjustment and tilt angle adjustment are required, since the support plate 301 at the bottom of the second hydraulic rod 302 is connected to the driving plate 208 through the driving rod 210, during the process of the first hydraulic rod 209 driving the first sliding column 203 to move upward, it can simultaneously drive the second hydraulic rod 302 to move upward, not only increasing the adjustment range of the tilt angle, but also when the two first hydraulic rods 209 at the front and rear lift the entire photovoltaic panel 7 to the highest position, it is still possible to adjust the tilt angle of the photovoltaic panel 7 through the second hydraulic rod 302, with strong practicability. And the U-shaped bolt 201 is buried in the central position in advance when pouring the cement pier 1, which is convenient for subsequent assembly of the base and improves the installation efficiency; Since the rotating shaft 306 at the top of the docking head 304 is connected to the sliding frame 502, and the sliding frame 502 can slide up and down along the first guide rod 501, when encountering strong winds or vibrations, the sliding frame 502 can drive the rotating shaft 306 and the mounting bracket 307 to move up and down, while compressing the first spring 503. The mounting bracket 307 drives the first load-bearing beam 401 and the photovoltaic panel 7 to move up and down. At this time, the first spring 503 plays a shock-absorbing effect, avoiding the problem that when the photovoltaic panel 7 vibrates due to factors such as strong winds and earthquakes, the connecting components of the photovoltaic panel 7 such as bolts and nuts become loose due to the fixed position of the photovoltaic panel 7. And the top cover 504 is clamped on the top of the docking head 304, playing a waterproof and dust-proof effect.
