Description

Technical Field

[0001] This invention relates to the field of photovoltaic module support technology, specifically an adjustable photovoltaic column. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic power generation has been widely used as an efficient and environmentally friendly energy solution. In photovoltaic power generation systems, photovoltaic pillars are a key component of photovoltaic support structures. Their main function is to support photovoltaic panels and ensure that the photovoltaic panels can maintain stable and efficient operation under different terrain and environmental conditions. Photovoltaic pillars not only need to have sufficient strength and stability to withstand the weight of the photovoltaic panels and the influence of external environmental factors, but also need to have a certain degree of flexibility to adapt to different terrains and installation requirements.

[0003] Traditional adjustable photovoltaic (PV) columns typically consist of a lower embedded steel pipe and an upper movable column located within the embedded steel pipe. The height of the PV column is adjusted by changing the position of the movable column. The upper part of the embedded steel pipe has three bolt holes spaced at 120-degree angles, into which corresponding bolts are installed. After the movable column's height is adjusted, it can be locked in place using the bolts in each direction to accommodate PV panels in complex terrain. However, in actual construction, it is difficult for a single person to adjust the height of the PV column. After adjustment, someone needs to hold the movable column to maintain its position before locking it in place with bolts. If the movable column has a large diameter and is heavy, it is difficult for a single person to maintain its position with one hand, requiring multiple people to adjust it simultaneously. This is inconvenient and wastes manpower. Therefore, to address these issues, an adjustable PV column is proposed. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, through the structure of clamping module, transmission roller assembly, and control module, the clamping module fixed on the pile can guide the vertical displacement of the movable column smoothly. On the other hand, when used in conjunction with the detachable transmission roller assembly and control module, the clamping module can be controlled by the construction worker's feet to clamp and position the adjusted movable column, thereby freeing the construction worker's hands. While maintaining the position of the movable column, the construction worker can tighten the positioning bolts in various directions to secure the movable column. This realizes that the various detachable mechanisms of the adjustable photovoltaic column allow the construction worker to easily and quickly adjust the height by a single person. It can be directly applied to existing adjustable photovoltaic columns with minimal changes in shape, eliminating the need for additional modifications during production, construction, and transportation. This solves the problem that existing adjustable photovoltaic columns require multiple operators for height adjustment, which is inconvenient and wastes manpower.

[0015] 2. In this invention, the transmission reset unit, clamping member, and positioning bolt are designed to ensure that the clamping member clamps and positions the loose positioning bolt under normal conditions. When the height of the movable column needs to be adjusted and the adjustment is completed, the clamping module of the clamping unit will cause the transmission reset unit to drive the clamping member to move, causing the clamping member to disengage from the positioning bolt. At this time, tightening the positioning bolt will fix the adjusted movable column. When the transmission roller assembly and control module installed on the clamping module are removed, the unrestricted transmission reset unit will simultaneously reset the clamping module and the clamping member, so that the reset clamping member automatically clamps and positions the positioning bolt, preventing the positioning bolt from loosening due to external factors such as vibration, thereby ensuring the fixing effect of the movable column.

A transmission roller assembly 5 is installed on the front side of the gear ring 42, inside the mounting port 416. The transmission roller assembly 5 includes a pair of pins 52 inserted into pin holes 43. This arrangement allows the transmission roller assembly 5 to be disassembled and assembled on the gear ring 42 according to the needs of the construction personnel. A middle plate 51 that fits against the front curved surface of the gear ring 42 is fixedly connected to the front end of the pins 52. Several rollers 53 arranged at equal intervals and angles are rotatably connected to the front side of the middle plate 51. A control module 6 is installed on the front side of the transmission roller assembly 5.Control module 6 includes a support frame 61, a drive unit 62, an extension plate 63, a pedal 64, a spring 65, a housing 66, and a clock spring 67. The support frame 61 is located on the front side of the frame 41. The support frame 61 includes a base frame 611 located on the front side of the pile tube 21. The upper and rear ends of the left and right side folding plates of the base frame 611 are provided with pin slots 612 that are open at the rear. The circular plates of the left and right side folding plates of the base frame 611 are provided with through shaft holes 613. The left and right side folding plates of the base frame 611 are provided with rail grooves 614 located below the shaft holes 613. The inner side of the crossbeam plate of the base frame 611 is provided with longitudinally spaced rail grooves. A through-type rail opening 615 is provided. A pair of upward-opening grooves 616 are formed on the inner side of the crossbeam plate of the base frame 611. Sleeves 66, fixedly connected to the base frame 611, are provided on the opposite sides of the left and right shaft holes 613. A drive unit 62 is installed on the front side of the transmission roller assembly 5. The drive unit 62 includes a reel 621 whose two ends are located inside the sleeves 66 on both sides and rotatably connected to the shaft holes 613. An arc-shaped cam 622 is fixedly connected to the outer side of the reel 621. One end of a pair of pull ropes 623 is fixedly connected to the outer side of the reel 621, and the pull ropes 623 are both wound around the outer side of the reel 621. The lower end of the pull ropes 623 is fixedly connected to... Simultaneously, the extension plate 63, which is slidably connected to the rail groove 614 and the rail opening 615, has a pedal 64 fixedly connected to its lower end. This configuration allows construction personnel to drive the control module 6 via foot, and in conjunction with the transmission roller assembly 5, drive the clamping module 4 to perform clamping actions. The height dimension of the toothed ring 42 is the same as the height dimension of the toothed groove 414. The upper and lower end faces of the toothed ring 42 are rotatably connected to the upper and lower inner walls of the toothed groove 414.

The curvature of the back strip 453 and the damping strip 454 is the same as the curvature of the outer curved surface of the movable column 3. This setting allows the damping strip 454 of each rotated clamping arm 45 to fully fit with the outer curved surface of the movable column 3 when the clamping module 4 performs the clamping action, thereby improving the clamping effect. The diameter of the movable column 3 is the same as the inner diameter of the guide port 412. This setting allows the guide port 412 to stably guide the vertical displacement of the movable column 3. The front side of the movable column 3 is provided with scale lines. This setting allows the construction personnel to adjust the position of the movable column 3 more accurately.The positioning pin 417 consists of a central pin body and damping plates fixed on the left and right sides of the central pin body. The positioning pin 417 is located inside the pin groove 612, and its outer end face is tightly fitted against the inner wall of the pin groove 612. This arrangement allows the control module 6 to be more stably mounted on the clamping module 4. The rollers 53 are all configured to cooperate with the arc-shaped cam 622. The front end of the roller 53 is located at the helical blade of the arc-shaped cam 622.

[0037] like Figure 3 , Figure 5 , Figures 14-18As shown, the upper part of the transmission reset part 7 is installed on the inner side of the annular groove 413. The transmission reset part 7 includes a base plate 71 fixedly connected to the inner wall of the annular groove 413. A limiting arc guide rod 72 is fixedly connected to the outer side of the base plate 71. A linkage block 73 fixedly connected to the toothed ring 42 is slidably connected to the outer side of the limiting arc guide rod 72. A spring 74 sleeved on the outer side of the limiting arc guide rod 72 is provided between the opposing surfaces of the linkage block 73 and the base plate 71. A linkage rod 75 located inside the pile tube 21 is fixedly connected to the lower end of the linkage block 73. Each of the connecting rods 75 has a clamping member 8 installed at its lower end to clamp and position the positioning bolt 24. The clamping member 8 includes a base block 81 fixed to the lower end of the connecting rod 75. A middle clamping block 82 is fixedly connected to the side of the base block 81 near the positioning bolt 24. An elastic damping pad 83 that fits tightly against the positioning bolt 24 is fixedly connected to the side of the middle clamping block 82 away from the base block 81. A pair of rod guide grooves 84 with back-to-back openings are opened on both sides of the interior of the middle clamping block 82. A limit guide rod 85 is slidably connected to the inner side of each rod guide groove 84. Each of the limiting guide rods 85 has a spring 86 in a tightened state fitted on its outer side. Side clamping blocks 87 are fixedly connected to the opposite ends of the upper and lower limiting guide rods 85. Elastic damping pads 88, which are tightly fitted to the positioning bolts 24, are fixedly connected to the inclined curved surfaces of the side clamping blocks 87. This arrangement ensures that the clamping component 8 will clamp and position the loose positioning bolts 24 under normal conditions. When the height of the movable column 3 needs to be adjusted and the adjustment is completed, the construction personnel will clamp the movable column 3 using the clamping module 4, which will cause the transmission reset part 7 to... The drive clamping member 8 is displaced, causing it to disengage from the positioning bolt 24. At this point, the movable column 3 can be fixed by tightening the positioning bolt 24. When the transmission roller group 5 and control module 6 installed on the clamping module 4 are removed, the transmission reset part 7, which is no longer restricted, will simultaneously reset the clamping module 4 and the clamping member 8, so that the reset clamping member 8 automatically clamps and positions the positioning bolt 24, preventing the positioning bolt 24 from loosening due to external factors such as vibration, thereby ensuring the fixing effect of the movable column 3.A notch is provided on the side of the base plate 71 away from the movable column 3. The toothed ring 42 is located inside the notch of the base plate 71. This arrangement ensures that the rotation of the toothed ring 42 is not interfered with by the base plate 71. The limiting guide rod 85 consists of a square rod and a square limiting washer. This arrangement ensures that the side clamping block 87 will only move longitudinally and will not rotate. Springs 86 are all located between the square limiting washer of the limiting guide rod 85 and the inner wall of the rod guide groove 84. Springs 86 are sleeved on the outside of the square rod of the limiting guide rod 85. This arrangement allows the elastic force of the upper and lower springs 86 to move the upper and lower side clamping blocks 87 toward each other, allowing the elastic damping pad 88 to fully and tightly fit with the positioning bolt 24. The elastic force of spring 74... The force is greater than the elastic force of spring 3 86. This setting allows the elastic force of spring 2 74 to overcome the elastic force of spring 3 86, enabling the clamping member 8 to automatically unfold and semi-enclose the positioning bolt 24 for clamping and positioning during reset. The outer side of the square limiting pad of the limiting guide rod 85 is provided with notches. This setting prevents the displacement of the limiting guide rod 85 from being affected by the air pressure inside the rod guide groove 84. The side of the side clamping block 87 away from the base block 81 is fixedly connected to a guide block 89. The arc surface of the guide block 89 is smoothly transitioned to the arc surface of the elastic damping pad 2 88. This setting allows the arc surface of the guide block 89 to provide guidance for the positioning bolt 24, allowing the positioning bolt 24 to smoothly slide into the interior of the clamping member 8.

[0038] Workflow: The construction, adjustment, and operation of the photovoltaic (PV) pillar are as follows. Note: The various detachable mechanisms in this application, including clamping module 4, transmission roller assembly 5, control module 6, transmission reset part 7, and clamping component 8, can be directly applied to existing adjustable PV pillars. During production, the manufacturer only needs to weld and fix the clamping module 4 to the top of the pile 2 to complete the modification of the existing adjustable PV pillar. During construction, construction personnel only need to use a single transmission roller assembly 5 and control module 6 to adjust and use all modified adjustable PV pillars. First, dig a suitable-sized pile pit according to construction requirements. Then, completely place the pillar burial cage 1 from this application into the pile pit, ensuring that the pile 2 remains above ground level. Next, pour concrete into the pile pit. After the concrete dries, the combined action of the concrete and the burial cage 1 will hold the pillar in place. The pile 2 is securely fixed; clamping operation during height adjustment: As part of the photovoltaic support, when the height of the column needs to be adjusted according to the construction design, the construction personnel first insert the pin 52 of the transmission roller group 5 into the pin hole 43 opened on the outside of the toothed ring 42 through the installation port 416, so that the transmission roller group 5 and the toothed ring 42 form a linkage relationship, completing the initial preparation operation. Then, the construction personnel hold the support guide 61 of the control module 6 and match the pin grooves 612 on both sides of the support guide 61 with the positioning pin block 417 of the frame 41, so that the positioning pin block 417 is inserted into the pin groove 612 of the support guide 61, and the arc cam 622 of the drive unit 62 matches each roller 53 of the transmission roller group 5, so that the control module 6 is hung on the clamping module 4 and the pile 2, and at the same time, the drive unit 62 and the transmission roller group 5 form a linkage relationship, completing all the preparation operations;At this point, the construction worker can hold the movable column 3 with both hands to adjust its vertical displacement. The height of the column can be precisely controlled based on the markings on the movable column 3. Once the position of the movable column 3 is adjusted, the worker presses down on the pedal 64 of the control module 6 with one foot. The downward movement of the pedal 64 causes the extension plate 63 to move downward, compressing the spring 65 (spring 65 is used for the subsequent automatic reset of the pedal 64). Simultaneously, the extension plate 63 pulls the pull rope 623 of the drive unit 62 downward, thereby causing the winding shaft 621 of the drive unit 62 to rotate backward. The backward rotation of the winding shaft 621 tightens the spring 67 (the spring...). The spring 67 is subsequently used to reset the reel 621, so that the reel 621 automatically rewinds the pull rope 623. On the other hand, it will drive the arc cam 622 to rotate backward, so that the transmission roller group 5 that cooperates with it will drive the gear ring 42 to rotate slightly clockwise from a top-down perspective under the drive of the arc cam 622. The slight clockwise rotation of the gear ring 42 will simultaneously drive each gear 44 that meshes with it to rotate clockwise from a top-down perspective, thereby driving each clamping arm 45 connected to it to rotate towards the movable column 3, until the damping strip 454 of each clamping arm 45 is tightly attached to the outer curved surface of the movable column 3, thus completing the clamping module 4 clamping the movable column 3. Figure 16 As shown; at this time, even if the worker loosens the movable column 3, it can maintain its height position, freeing the worker's hands and preparing for the subsequent tightening operation; at the same time, the rotation of the gear ring 42 will also synchronously drive the linkage blocks 73 of each transmission reset part 7 to move towards the base plate 71 with the limit arc guide rod 72 as the guide, and squeeze the spring 74. The displacement of each linkage block 73 will synchronously drive each clamping member 8 to move through each linkage rod 75, so that the clamping member 8 after displacement will disengage from the positioning bolt 24 and no longer clamp and position the positioning bolt 24, preparing for the subsequent tightening operation. The side clamping block 87 and the limit square guide rod 85 of each clamping member 8 will also move towards the center clamping block 82 under the elastic unfolding of the spring 86, completing the folding of the clamping member 8. Figure 18As shown, through the above operations, the various detachable mechanisms of the adjustable photovoltaic column allow construction personnel to easily and quickly adjust the height by a single person. It can be directly applied to existing adjustable photovoltaic columns. Since it is a design improvement on existing photovoltaic columns without altering the original structure, its dimensional changes are minimal, thus eliminating the need for additional modifications during construction and transportation, as well as during production. Only a production line for each detachable mechanism needs to be added. This solves the problem that existing adjustable photovoltaic columns require multiple operators for height adjustment, which is inconvenient and wastes manpower. Tightening operation: After the previous operation is completed, the construction personnel can tighten the positioning bolts 24 surrounding the movable column 3. This allows the positioning bolts 24 to initially tighten and clamp the movable column 3 from all directions, thus completing the first fixing of the movable column 3. Subsequently, the construction personnel release the pedal 64 that has been pressed down and remove the control module 6 and transmission roller assembly 5 from the clamping module 4. The removed control module 6 and transmission roller assembly 5 can continue to be used for subsequent adjustment work on other modified adjustable photovoltaic columns. After the control module 6 and transmission roller assembly 5 are removed, the springs 74 of each transmission reset part 7, which were originally restricted, immediately perform elastic reset. Their elastic force pushes each linkage block 73 to move back along the guide trajectory of each limit arc guide rod 72. The return movement of each linkage block 73 drives the gear ring 42 to rotate in the opposite direction, thereby driving the gear 4 meshing with it. 4. The clamping arm 45 is returned to its initial position. At the same time, the return of each linkage block 73 is also pulled by the linkage rod 75 to move each clamping member 8 toward the positioning bolt 24. During this process, the guide blocks 89 on the upper and lower sides of the clamping member 8 first contact the positioning bolt 24. Using the guiding effect provided by the arc surface of the guide block 89, the positioning bolt 24 can be smoothly slid into the clamping member 8. Since the elastic force of spring 2 74 is greater than that of spring 3 86, spring 2 74 can overcome the elastic force limitation of spring 3 86. Under the continuous push of the elastic force of spring 2 74, the side clamping blocks 87 on the upper and lower sides will drive the limiting guide rod 85 to move backward along the rod guide groove 84 and compress spring 3 86, so that the clamping member 8 changes from the closed state to the closed state. In the unfolded state, the upper and lower side clamping blocks 87 and the middle clamping block 82, under the combined action of the elastic damping pad 1 83, the elastic damping pad 2 88, and the spring 3 86, semi-enclose and clamp the positioning bolt 24, thereby preventing the positioning bolt 24 from loosening due to external vibrations or other adverse factors, and ensuring that the positioning bolt 24 reliably fixes the movable column 3. Finally, the construction personnel insert the drill rod of the external drilling equipment into the bolt hole 26 to precisely pierce the movable column 3 in the pile pipe 21. After the piercing is completed, the external pin is then inserted through the bolt hole 26 into the movable column 3 to complete the final fixation of the movable column 3, ensuring that the photovoltaic column can maintain the set height for a long time even in harsh environments.
