Description

Technical Field

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

[0002] A flexible photovoltaic bracket is a type of photovoltaic bracket used to fix solar panels. A flexible photovoltaic bracket usually consists of flexible load-bearing cables, steel columns, steel inclined columns or stay cables, steel beams and foundations, and has advantages such as simple structure, less material use, light weight, and short construction period that traditional brackets lack;

[0003] For example, a cable force adjusting device for a flexible photovoltaic bracket of "CN116915137B" includes a first base plate and a second base plate. A support column is fixedly installed at the top of the first base plate. A telescopic column is movably installed inside the support column. A connecting frame and a connecting shaft seat are respectively fixedly installed on the outer side of the top of the telescopic column. A first connecting rope is movably connected between two connecting frames on the same horizontal line. Through the operation of the first motor, the first motor can drive the first threaded column to rotate through a driving gear and a driven gear. When the first threaded column rotates, it will drive the telescopic column to rise and fall in the support column through a first moving block and a first threaded groove. When one telescopic column descends in height and the other telescopic column does not move and does not change height, the first connecting rope will be inclined, and thus the photovoltaic panel will also change the inclination angle, and the angle change of the photovoltaic panel can be achieved;

[0004] However, in the prior art, as shown in the above patent, the adjustment of the stay cable only relies on the drive of the motor to drive the stay cable to wind. The stay cable has strong toughness, and multiple flexible photovoltaic brackets need to be slidably installed on each stay cable. After installation, the stay cable has a large weight. In the adjustment step of tightening it, the simple process of winding the stay cable easily causes the stay cable to slip or even be difficult to wind to a tight state. If you want to wind the stay cable to a tight state, it may require extra effort. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem that in the prior art, the simple process of winding the stay cable easily causes the stay cable to slip or even be difficult to wind to a tight state.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a cable force adjusting device for a flexible photovoltaic support, which includes two groups of support seats, a top adjusting mechanism and a bottom adjusting mechanism. The top adjusting mechanism is arranged at the top end of the support seat, and the bottom adjusting mechanism is arranged on the ground on one side of the support seat. A main cable for installing a photovoltaic panel is arranged between the two groups of top adjusting mechanisms. The end face of the main cable penetrates through the top adjusting mechanism and is assembled and connected with the bottom adjusting mechanism. The top adjusting mechanism includes a top seat and a one-way wheel. The top seat is arranged at the upper end of the support seat, and the one-way wheel is rotatably arranged on the top seat. The main cable is wound on the one-way wheel. The bottom adjusting mechanism includes a base, an adjusting wheel, a gear ring, a worm gear and a worm. The lower end of the base is buried in the ground. The adjusting wheel is rotatably arranged inside the base. A slideway is arranged inside the base. The gear ring is slidably arranged in the slideway. The lower part of the adjusting wheel meshes with the gear ring. An installation frame is arranged inside one end of the base. The worm gear and the worm are respectively rotatably arranged in the installation frame and mesh with each other. The worm gear is linked with a first gear through a chain, and the first gear meshes with the gear ring. The worm is driven to rotate by a first motor.

[0009] Further, the number of turns of the main cable wound on the one-way wheel is not less than ten. Positioning members are respectively arranged at the feeding end and the discharging end of the top seat. The positioning members include fixed tubes, push blocks and first springs. A plurality of push blocks are provided and are rotatably arranged at one end away from the base inside the fixed tubes. The main cable slidably passes between the plurality of push blocks. The other end of the push block is assembled and connected with the inner wall of the fixed tube through the first spring. When the main cable is tightened, the moving direction of the main cable can push the push blocks away, the first spring is compressed, and the main cable moves smoothly. When the main cable moves in the reverse direction, the tip of the push block applies pressure to the surface of the main cable to squeeze the main cable. With the push of the first spring, it is difficult for the main cable to slip off.

[0010] Further, the fixed tube is composed of two half tubes. One side of the two half tubes is rotatably connected and the other side is assembled and connected through a first bolt. A fixed frame is arranged on the top seat. The fixed tube is arranged in the fixed frame and fixed through a second bolt. When disassembling the fixed tube, by removing the second bolt, taking the fixed tube out of the fixed frame, and taking out the first bolt, the two half tubes are opened, so that the internal push blocks are separated from the main cable, which is convenient for disassembling the main cable.

[0011] Furthermore, a first ratchet is provided on the end face of the one-way wheel, and a first pawl is rotatably provided on the top seat, the end face of the first pawl is engaged with the side edge of the first ratchet, the first pawl is assembled and connected to the top seat through a second spring, and a second motor is provided on the top seat, and the one-way wheel is driven to rotate by the second motor. When the second motor is driven, the one-way wheel and the first ratchet on its end face are driven to rotate. Under the action of the second spring, the end face of the first pawl is always against the side edge of the first ratchet, and when the main cable is pulled, the first ratchet can rotate smoothly. When rotating in the opposite direction, the first pawl resists the ratchet teeth on the side edge of the first ratchet to prevent it from rotating, thereby preventing the one-way wheel from reversing and slipping.

[0012] Furthermore, toothed discs meshing with toothed rings are symmetrically provided at both ends of the adjusting wheel, a second ratchet is provided on the outer side of the toothed disc, a second pawl adapted to the second ratchet is rotatably provided on the upper inner side of the base, and the second pawl is assembled and connected to the base through a third spring. Through the cooperation of the second pawl and the second ratchet, the adjusting wheel rotates to drive the main cable to be wound and is difficult to rotate in the opposite direction, causing the main cable to be derailed, thereby ensuring the stability of the main cable and the tension of the main cable after the cable force is adjusted.

[0013] Furthermore, the slide is arranged in a ring-shaped structure, and a plurality of supporting gears arranged to mesh with the gear ring are rotatably provided on the inner side of the slide. The lower side of the gear ring meshes with the lower side of the inner ring of the supporting gear, and the first gear meshes with the outer ring of the gear ring. The plurality of supporting gears are arranged to support the gear ring during rotation, thereby ensuring the stability of rotation and avoiding tooth disengagement.

[0014] Furthermore, the worm wheel is rotatably connected to the mounting frame via a rotating shaft, a sprocket is linked to the rotating shaft, a diameter of the sprocket is much larger than a diameter of the first gear, the first gear and the sprocket are linked via a chain, the worm wheel is driven to rotate by rotating the worm, and then the sprocket is driven to rotate, and the first gear is driven to rotate by the chain. In addition, since the diameter of the sprocket is larger than the diameter of the first gear, the rotation of the first gear is more labor-saving and the first gear rotates faster.

[0015] Furthermore, an assembly groove is provided inside one end of the base, and the mounting frame is slidably arranged in the assembly groove. The side of the mounting frame away from the adjusting wheel is assembled and connected to the inner wall of the base through a fifth spring. An insertion strip is slidably penetrated through the base on the side of the mounting frame away from the adjusting wheel. The insertion strip has a wide upper part and a narrow lower part structure and is located between the mounting frame and the assembly groove. In the initial state, the fifth spring pulls the mounting frame to move toward the side away from the adjusting wheel. When the insertion strip is inserted, the insertion strip pushes the mounting frame to the other side until the first gear is meshed with the outer wall of the gear ring. In this state, the insertion strip is just inserted to the bottom. When disassembling, it only needs to pull out the insertion strip, and the fifth spring pulls the mounting frame to separate the first gear from the gear ring.

[0016] Furthermore, the disassembly structures of the first ratchet disc and the first ratchet pawl are the same as those of the second ratchet disc and the second ratchet pawl. A bracket is provided below the second ratchet pawl. The bracket is slidably connected to the inner wall of the base. A third gear meshing with the side of the bracket is rotatably provided in the base on one side of the bracket. An extraction bar is provided above the outside of the base. The lower end of the extraction bar is slidably arranged inside the base and meshes with the third gear on one side. By pushing and moving the extraction bar downward, the third gear is driven to rotate, and then the bracket is driven to move upward. When the bracket moves upward, one end of the second ratchet pawl close to the second ratchet disc can be lifted and separated from it. At this time, the second ratchet disc can rotate freely, and the main cable can also be smoothly disengaged. On the contrary, when moving downward, the second ratchet pawl can be pushed to be close to the second ratchet disc. When the second ratchet disc continues to rotate, the second ratchet pawl can mesh with it.

[0017] Furthermore, a protective film is provided on the outer wall of the base. The extraction bar is located inside the protective film. One end of the extraction bar arranged outside the base is assembled and connected to the base through a fourth spring. The provided protective film is used to protect the extraction bar and the fourth spring. In addition, the setting of the fourth spring can push the extraction bar to always move toward the outside of the base.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. When the cable force of the present invention is adjusted, by driving the adjusting wheel to rotate, more main cables are wound around the adjusting wheel. The cooperation of the worm gear and the worm has a self-locking effect, making it difficult for the toothed ring to be pushed to slide reversely, ensuring the stability of the main cable and being more labor-saving. When winding the cable, the main cable will pass through the one-way wheel. When the one-way wheel rotates, it will pull the main cable toward the base, making the main cable between the two support seats tightened. And the one-way rotation of the one-way wheel makes it difficult for it to rotate reversely to reset the main cable. In addition, the setting of the positioning member can lock the main cable, effectively saving the labor for preventing the main cable from slipping during the process of pulling the main cable to the bottom adjusting mechanism.

[0020] 2. When the main cable of the present invention is tightened, the moving direction of the main cable can push the push block away, and the first spring is compressed. The main cable moves smoothly. When the main cable moves reversely, the tip of the push block exerts pressure on the surface of the main cable to squeeze the main cable. With the push of the first spring, it is difficult for the main cable to slip off.

[0021] 3. Through the cooperation of the second ratchet pawl and the second ratchet disc of the present invention, it is difficult for the adjusting wheel to rotate reversely after driving the main cable to wind, resulting in the situation of the main cable slipping off, ensuring the stability of the main cable and the tightened state of the main cable after the cable force is adjusted.

[0022] 4. Through the multiple support gears provided in the present invention, they are used to support the toothed ring during the rotation process, ensuring the stability of the rotation and avoiding the situation of tooth disengagement. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Secondly, as referred to herein, "one embodiment" or "an embodiment" means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0037] Please refer to Figures 1-8, the present invention provides a technical solution: a cable force adjustment device for a flexible photovoltaic support, which includes two groups of support seats 1, a top adjustment mechanism and a bottom adjustment mechanism. The top adjustment mechanism is arranged at the top of the support seat 1, and the bottom adjustment mechanism is arranged on the ground on one side of the support seat 1. A main cable 2 for installing a photovoltaic panel is arranged between the two groups of top adjustment mechanisms. The end face of the main cable 2 penetrates through the top adjustment mechanism and is assembled and connected with the bottom adjustment mechanism. The top adjustment mechanism includes a top seat 311 and a one-way wheel 312. The top seat 311 is arranged at the upper end of the support seat 1, and the one-way wheel 312 is rotatably arranged on the top seat 311. The main cable 2 is wound around the one-way wheel 312. The bottom adjustment mechanism includes a base 411, an adjustment wheel 412, a toothed ring 413, a worm gear 414 and a worm 415. The lower end of the base 411 is buried in the ground. The adjustment wheel 412 is rotatably arranged inside the base 411. A slideway 416 is arranged inside the base 411. The toothed ring 413 is slidably arranged in the slideway 416. The lower part of the adjustment wheel 412 meshes with the toothed ring 413. An installation frame 417 is arranged inside one end of the base 411. The worm gear 414 and the worm 415 are respectively rotatably arranged inside the installation frame 417 and mesh with each other. The worm gear 414 is linked with a first gear 422 through a chain 421, and the first gear 422 meshes with the toothed ring 413. The worm 415 is driven to rotate by a first motor 423.

[0038] As Figures 1-8 shown, the number of turns of the main cable 2 wound around the one-way wheel 312 is not less than ten turns. Positioning members 5 are respectively arranged at the feeding end and the discharging end of the top seat 311. The positioning members 5 include fixed tubes 511, push blocks 512 and first springs 513. A plurality of push blocks 512 are provided and are rotatably arranged at one end away from the base 411 inside the fixed tube 511. The main cable 2 slidably passes through between the plurality of push blocks 512. The other end of the push block 512 is assembled and connected with the inner wall of the fixed tube 511 through the first spring 513. When the main cable 2 is tightened, the moving direction of the main cable 2 can push open the push block 512, and the first spring 513 is compressed, so that the main cable 2 can move smoothly. When the main cable 2 moves in the reverse direction, the tip of the push block 512 applies pressure to the surface of the main cable 2 to squeeze the main cable 2. With the push of the first spring 513, it is difficult for the main cable 2 to slip off.

[0039] As Figures 1-8 shown, the fixed tube 511 is composed of two half tubes 521. One side of the two half tubes 521 is rotatably connected and the other side is assembled and connected through a first bolt 522. A fixed frame 523 is arranged on the top seat 311. The fixed tube 511 is arranged inside the fixed frame 523 and fixed through a second bolt 524. When disassembling the fixed tube 511, by removing the second bolt 524, taking the fixed tube 511 out of the fixed frame 523 and taking out the first bolt 522, the two half tubes 521 are opened, so that the internal push block 512 is separated from the main cable 2, which is convenient for disassembling the main cable 2.

[0040] like Figures 1-8 As shown, a first ratchet 611 is provided on the end face of the one-way wheel 312, and a first pawl 612 is rotatably provided on the top seat 311. The end face of the first pawl 612 is engaged with the side of the first ratchet 611, and the first pawl 612 is assembled and connected to the top seat 311 through a second spring 613. A second motor 614 is provided on the top seat 311, and the one-way wheel 312 is driven to rotate by the second motor 614. When the second motor 614 is driven, the one-way wheel 312 and the first ratchet 611 on its end face are driven to rotate. Under the action of the second spring 613, the end face of the first pawl 612 is always against the side of the first ratchet 611. When the main cable 2 is pulled, the first ratchet 611 can rotate smoothly. When rotating in the opposite direction, the first pawl 612 presses against the ratchet teeth on the side of the first ratchet 611 to prevent it from rotating, thereby preventing the one-way wheel 312 from reversing and slipping.

[0041] like Figures 1-8 As shown, toothed discs 711 meshing with the toothed ring 413 are symmetrically provided at both ends of the adjusting wheel 412, a second ratchet 712 is provided on the outer side of the toothed disc 711, and a second pawl 713 adapted to the second ratchet 712 is rotatably provided on the upper inner side of the base 411, and the second pawl 713 is assembled and connected to the base 411 through a third spring 714. Through the cooperation of the second pawl 713 and the second ratchet 712, the adjusting wheel 412 is rotated to drive the main cable 2 to be difficult to rotate in the opposite direction after winding, causing the main cable 2 to be off-line, thereby ensuring the stability of the main cable 2 and the tension of the main cable 2 after the cable force is adjusted.

[0042] like Figures 1-8 As shown, the slide 416 is arranged in a ring-shaped structure, and a plurality of supporting gears 721 arranged to mesh with the gear ring 413 are rotatably arranged on the inner side of the slide 416. The gear ring 413 meshes with the lower part of the inner ring of the supporting gear 721, and the first gear 422 meshes with the outer ring of the gear ring 413. The plurality of supporting gears 721 are arranged to support the gear ring 413 during the rotation process, thereby ensuring the stability of the rotation and avoiding the situation of tooth disengagement.

[0043] like Figures 1-8 As shown, the worm wheel 414 is rotatably connected to the mounting frame 417 via a rotating shaft 732, and a sprocket 733 is linked to the rotating shaft 732. The diameter of the sprocket 733 is much larger than the diameter of the first gear 422. The first gear 422 and the sprocket 733 are linked via a chain 421, and the worm wheel 414 is driven to rotate by rotating the worm 415, thereby driving the sprocket 733 to rotate, and the chain 421 cooperates to drive the first gear 422 to rotate. In addition, since the diameter of the sprocket 733 is larger than the diameter of the first gear 422, the first gear 422 can be rotated more labor-saving and faster.

[0044] like Figures 1-8As shown, an assembly groove 741 is provided inside one end of the base 411. The mounting bracket 417 is slidably disposed in the assembly groove 741. The side of the mounting bracket 417 away from the adjusting wheel 412 is assembled and connected to the inner wall of the base 411 through a fifth spring 743. A plug 742 is slidably inserted through the base 411 on the side of the mounting bracket 417 away from the adjusting wheel 412. The plug 742 has a structure that is wider at the top and narrower at the bottom and is located between the mounting bracket 417 and the assembly groove 741. In the initial state, the fifth spring 743 pulls the mounting bracket 417 to move away from the adjusting wheel 412. When the plug 742 is inserted, the plug 742 pushes the mounting bracket 417 to the other side until the first gear 422 meshes with the outer wall of the toothed ring 413. In this state, the plug 742 just inserts to the lowest position. When disassembling, just pull out the plug 742, and the fifth spring 743 pulls the mounting bracket 417 to separate the first gear 422 from the toothed ring 413.

[0045] As Figures 1-8 shown, the disassembly structure of the first ratchet disc 611 and the first ratchet pawl 612 is the same as that of the second ratchet disc 712 and the second ratchet pawl 713. A bracket 751 is provided below the second ratchet pawl 713. The bracket 751 is slidably connected to the inner wall of the base 411. A third gear 752 meshing with the side of the bracket 751 is rotatably provided inside the base 411 on one side of the bracket 751. A disassembly strip 753 is provided above the outside of the base 411. The lower end of the disassembly strip 753 is slidably disposed inside the base 411 and meshes with the third gear 752 on one side. By pushing and moving the disassembly strip 753 downward, the third gear 752 is driven to rotate, and then the bracket 751 is driven to move upward. The upward movement of the bracket 751 can lift and separate the end of the second ratchet pawl 713 close to the second ratchet disc 712. At this time, the second ratchet disc 712 can rotate freely, and the main cable 2 can also be smoothly detached. On the contrary, when moving downward, the second ratchet pawl 713 can be pushed to be close to the second ratchet disc 712. When the second ratchet disc 712 continues to rotate, the second ratchet pawl 713 can mesh with it.

[0046] As Figures 1-8 shown, a protective film 761 is provided on the outer wall of the base 411. The disassembly strip 753 is located inside the protective film 761. The disassembly strip 753 is assembled and connected to the base 411 through a fourth spring 762 at the outer end of the base 411. By providing the protective film 761, it is used to protect the disassembly strip 753 and the fourth spring 762. In addition, the setting of the fourth spring 762 can push the disassembly strip 753 to always move toward the outside of the base 411.

[0047] Working principle: When adjusting the cable force, by driving the adjusting wheel 412 to rotate, more main cables 2 are wound around the adjusting wheel 412. When winding the cable, the main cable 2 passes through the one-way wheel 312. When the one-way wheel 312 rotates, it will pull the main cable 2 towards the base 411, making the main cable 2 between the two support seats 1 taut. And the one-way rotation of the one-way wheel 312 makes it difficult to reverse-rotate to reset the main cable 2. In addition, the setting of the positioning member 5 can lock the main cable 2. During the process of pulling the main cable 2 to the bottom adjusting mechanism, it effectively saves the labor for preventing the main cable 2 from slipping during pulling. The specific steps for driving the rotation of the adjusting wheel 412 are as follows: By driving the first motor 423, the worm 415 is driven to rotate, and then the worm gear 414 meshed with it is driven to rotate. The first gear 422 is driven to rotate through the chain 421. The first gear 422 drives the tooth ring 413 to slide in the slideway 416. The tooth ring 413 moves smoothly towards the bottom of the adjusting wheel 412. When moving, the tooth ring 413 meshes with the bottom of the adjusting wheel 412, driving the adjusting wheel 412 to rotate, realizing further winding of the main cable 2 on the adjusting wheel 412. Among them, the cooperation of the worm gear 414 and the worm 415 has a self-locking effect, making it difficult for the tooth ring 413 to be pushed to slide in the reverse direction, ensuring the stability of the main cable 2 and being more labor-saving.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
