Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a flexible fixed bracket for a photovoltaic power station. Background Art

[0002] With the increasing attention paid to renewable energy around the world, photovoltaic power stations, as one of the main forms of solar energy utilization, have seen rapid development in both construction scale and technology level. In the construction of photovoltaic power stations, the fixed brackets of photovoltaic panels are an indispensable key component, which is directly related to the installation stability, power generation efficiency and maintenance convenience of photovoltaic panels. Traditional photovoltaic power station fixed brackets mostly use rigid structures, such as steel frames. Although the structure is stable, its adaptability and installation efficiency are insufficient in scenarios with complex terrain, flexible layout or maximum space utilization.

[0003] In recent years, a new type of bracket system called "flexible fixed bracket for photovoltaic power station" has emerged to solve the above problems and provide a more flexible and efficient installation solution. The existing flexible fixed bracket for photovoltaic power station is mainly composed of steel columns, conical seats, tripods and wire ropes. As a supporting structure, the bottom of the steel column is firmly connected to the ground through a conical seat, and the top is connected to a tripod. The tripod is designed to provide multi-angle support to adapt to different lighting conditions and installation requirements. The two ends of the tripod are fixedly connected to the wire rope through bolts and arc pieces to form an integrated support system for hanging and fixing photovoltaic panels.

[0004] However, although this flexible fixed bracket has improved the flexibility of installation to a certain extent, it still faces a series of challenges in practical applications: the first is the installation height and hoisting problem: since the entire bracket system is relatively high, the steel column and its top components (such as the tripod) need to be hoisted and kept in a vertical state with the help of hoisting equipment during the installation process, which not only increases the installation cost, but also may increase the safety risk during the installation process; the second is the complicated way of fixing the wire rope: the wire rope is fixed to the tripod by bolts and arc pieces. This fixing method brings inconvenience when assembling the bracket. If the wire rope is installed in advance, it is difficult to erect the steel column smoothly. If it is installed later, high-altitude operations are required, which is not only complicated and inefficient, but also increases the safety risks of operators. In addition, the fixing method of bolts and arc pieces also increases the difficulty of later maintenance, especially when replacing the wire rope, it is necessary to repeat the tedious disassembly and installation steps; the third is the difficulty in adjusting the angle of the tripod: the angle of the tripod is usually fixed, but in practical applications, in order to maximize the light-receiving area of ​​the photovoltaic panel, it may be necessary to fine-tune the angle according to specific environmental conditions. The existing fixing method makes this process cumbersome, further reducing the installation efficiency. Summary of the invention

Its folding stepped design not only simplifies the photovoltaic panel angle adjustment steps and ensures that the preset angle is reached after installation, but also has a small volume after folding, which is convenient for transportation, and can flexibly adjust the number of unfolded frames according to the size of the photovoltaic panel.

The ladder frame 10 includes a first frame 11, a second frame 12, a third frame 13 and a fourth frame 14 which are arranged in sequence in the horizontal direction and whose height and width decrease in sequence. The second frame 12, the third frame 13 and the fourth frame 14 are respectively located in the installation cavity 15 of the first frame 11, the second frame 12 and the third frame 13, and a connecting rod 16 is arranged between the inner wall of the installation cavity 15, the surface of the first frame 11 is provided with a walking wheel 17, and the outer sides of the first frame 11, the second frame 12 and the third frame 13 are provided with a walking wheel 17. The surfaces are respectively provided with cross braces 18, one end of the cross braces 18 is connected to the connecting rod 16, and the other end of the cross braces 18 is respectively connected to the elastic clamps 19 on the surfaces of the second frame 12, the third frame 13 and the fourth frame 14, the inner surfaces of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are respectively provided with connecting parts 110, the lower end surface of the first frame 11 is rotatably connected with an outer frame 111, and the surface of the outer frame 111 is symmetrically provided with elastic limiters 112, which are respectively in contact with the surfaces of the second frame 12, the third frame 13 and the fourth frame 14; The connecting seat assembly 2 includes a steel cable seat 21 and a fixing seat 22. The steel cable seat 21 and the fixing seat 22 are respectively arranged on the connecting portion 110 and in corresponding positions. A winding and fixing mechanism 23 and a quick connection mechanism 24 are respectively arranged inside the steel cable seat 21 and on the surface of the fixing seat 22; Steel cable assembly 3: includes steel cables 31 and connecting columns 32. There are two groups of steel cables 31. One end of the two groups of steel cables 31 is connected to the winding and fixing mechanism 23, and the other end of the two groups of steel cables 31 is connected to the quick connection mechanism 24. The connecting columns 32 are evenly arranged on the inner wall of the steel cables 31. The inner wall of the connecting column 32 is symmetrically reversely threaded with a hook seat 33. The hook seats 33 on the two adjacent groups of steel cables 31 are connected by a cross elastic connecting belt 34.

[0022] Specifically, the present invention has a reasonable structure. Traditional bracket systems often need to rely on lifting equipment to lift the components to high altitudes for installation, which not only increases the installation cost but also is accompanied by higher safety risks. The bracket assembly 1 of the present invention is uniquely designed and can be installed directly on the ground without the need for lifting operations, thereby greatly reducing installation costs and safety risks. The bracket assembly 1 of the present invention adopts a folding ladder design, which enables the multiple sets of steel cables 31 to be automatically on the same oblique line after installation, without the need for additional adjustment of the angle of the photovoltaic panel, greatly simplifying the installation process, saving manpower and time. At the same time, the folding design greatly reduces the volume of the bracket assembly 1 during transportation, making it easier to transport. and storage. In addition, by adjusting the number of unfolded frames, the bracket assembly 1 can flexibly adapt to photovoltaic panels of different sizes, thereby improving the flexibility and versatility of use. In traditional bracket systems, steel wire ropes usually need to be fixed to the bracket one by one by bolts and arc-shaped sheets. This process is cumbersome and time-consuming. The present invention integrates the steel cable 31 on the connecting seat assembly 2, and realizes the rapid fixation of the steel cable 31 through the quick connection mechanism between the connecting seat assembly 2 and the bracket assembly 1. This design not only simplifies the installation steps and improves the installation efficiency, but also enables the entire connecting seat assembly 2 to be directly and quickly disassembled for replacement or repair when the steel cable 31 is damaged, thereby greatly reducing the difficulty and time cost of repair.

[0023] When in use, first drive the first frame body 11 to the set position through the walking wheel 17, then stand up the first frame body 11, then loosen and tighten the handle 600 to separate the top of the outer frame 111 from the top of the first frame body 11, and then slowly lower the outer frame 111 through the handle part 500, then open the fixing ring 300, and cooperate with the fixing bolt 400 with the fixing ring 300 to fix the outer frame 111 to the ground. After the fixing is completed, the second frame body 12 is pulled out of the installation cavity 15 of the first frame body 11 through the drawing groove 200 on the surface of the second frame body 12. After the second frame body 12 is pulled out, the slider 161 connected to the connecting rod 16 moves down along the inner wall of the installation cavity 15 and the surface of the second frame body 12 respectively, and triggers the cross brace 18 to rotate. When the second frame body 12 is pulled out to the maximum stroke, the elastic limit member 112 on the outer frame 111 limits the second frame body 12 to prevent it from moving horizontally, and the cross brace After the rotation, the other end of 18 is engaged and fixed with the elastic clamp 19 on the surface of the second frame 12, so as to connect and support the first frame 11 and the second frame 12. Then, the third frame 13 and the fourth frame 14 are pulled out in sequence according to the above steps. After all the frames are pulled out, the steel cable seat 21 and the fixing seat 22 are taken out from the drawer 100, and then the steel cable seat 21 and the fixing seat 22 are respectively connected to the connecting part 110. After the steel cable seat 21 and the fixing seat 22 are connected and fixed, the steel cable 31 is pulled out from the inside of the steel cable seat 21 and connected and fixed with the quick connection mechanism 24 on the surface of the fixing seat 22. The steel cable 31 can be quickly wound and fixed by the winding and fixing mechanism 23. After the steel cable 31 is pulled out, in order to improve the structural strength and stability between the two adjacent groups of steel cables 31, the cross elastic connecting belt 34 is taken out from the drawer 100 and connected to the hook seat 33 inside the connecting column 32 on the steel cable 31.

[0024] In one embodiment of the present invention, Figure 4 As shown, the lower end of the connecting rod 16 is hingedly fixed to the lower inner wall of the installation cavity 15, the second frame 12, the third frame 13 and the lower end surface of the fourth frame 14, respectively, and the upper end of the connecting rod 16 is hingedly fixed with a slider 161, and the slider 161 is vertically slidably connected to the upper inner wall of the installation cavity 15, the second frame 12, the third frame 13 and the upper end surface of the fourth frame 14, respectively, wherein the surface of the slider 161 located on the upper inner wall of the installation cavity 15 is provided with a tooth portion 162.

[0025] Specifically, the structure and connection relationship of the connecting rod 16 are further described. The connecting rod 16 plays a vital role in the overall structure through its sophisticated design and stable connection method. It can not only connect the various frames together tightly, but also realize specific transmission and control functions, thereby ensuring the stability and reliability of the overall structure. During the operation of the overall structure, the connecting rod 16 tightly connects the installation cavity 15, the second frame 12, the third frame 13 and the fourth frame 14 through the hinged connection at its upper and lower ends. When the frame is pulled out, the slider 161 will slide vertically on the inner wall of the installation cavity 15, the second frame 12, the third frame 13 and the fourth frame 14. At the same time, the tooth portion 162 on the surface of the slider 161 located on the inner wall of the upper end of the installation cavity 15 will engage and cooperate with other transmission components to achieve specific transmission or control functions. This design not only improves the stability and reliability of the overall structure, but also enhances its adaptability and flexibility.

[0026] In one embodiment of the present invention, Figure 4 As shown, one end of the cross support frame 18 is rotatably connected to the outer surfaces of the first frame 11, the second frame 12 and the third frame 13, respectively, and the other end of the cross support frame 18 is respectively clamped and fixed with the elastic clamps 19 on the surfaces of the second frame 12, the third frame 13 and the fourth frame 14. One end of the central axis of the cross support frame 18 passes through the installation cavity 15 and is fixedly connected with a driving gear 181. The driving gear 181 is located on one side of the tooth portion 162 and is meshed with the teeth on the surface of the tooth portion 162.

[0027] Specifically, the structure and connection relationship of the cross brace 18 are further explained. As a key component, the cross brace 18 is designed to improve the connection stability between the frames (such as the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14) and enhance the overall structural strength.

[0028] During use, when the slider 161 is moved downward by external force (such as manual operation), the tooth portion 162 thereon will contact and mesh with the driving gear 181. As the slider 161 continues to move, the driving gear 181 will drive the cross support frame 18 to rotate. When the slider 161 moves to a specific position (such as the lowest point), the tooth portion 162 separates from the driving gear 181. At this time, the connecting groove of the cross support frame 18 will be tightly engaged with the elastic clip 19 on the surface of the second frame 12, the third frame 13 and the fourth frame 14, thereby fixing the position of the cross support frame 18. This design not only improves the connection stability between the frames, but also enhances the overall structural strength, ensuring the use effect.

The first frame body 11, the second frame body 12, the third frame body 13 and the fourth frame body 14 have a first square groove 101 and a second square groove 102 respectively formed on the inner surface corresponding to the position of the connecting portion 110. The limiting shaft rod 1101 is symmetrically fixedly connected to the inner top wall of the first square groove 101. The conical clamp 1102 is symmetrically arranged on the surface of the limiting shaft rod 1101. The seat 1103 is vertically slidably connected to the inner wall of the second square groove 102, one end of the cylinder seat 1103 passes through the first square groove 101, and is sleeved on the outside of the limiting shaft 1101. A card groove is opened on the surface of the cylinder seat 1103, and is clamped and fixed with the conical clamp 1102. The limiting column 1104 is located in the second square groove 102 and fixedly connected to the surface of the cylinder seat 1103. The steel cable seat 21 and the fixed seat 22 are respectively clamped and fixed on the inner wall of the second square groove 102, and are sleeved on the outside of the limiting column 1104.

[0030] It should be noted that limiting column holes are provided on the surfaces of the steel cable seat 21 and the fixing seat 22 at locations corresponding to the positions of the limiting columns 1104 .

[0031] Specifically, the structure and connection relationship of the connection part 110 are further described. The connection part 110 realizes a quick connection and a firm fixation with the steel cable seat 21 and the fixing seat 22 by its sophisticated design and firm connection method.

[0032] During the installation process, first place the steel cable seat 21 and the fixing seat 22 into the second square groove 102, then lift the cylinder seat 1103 at one end inside the first square groove 101, and make the groove on its surface engage and fix with the conical clamp 1102. After engaging and fixing, the limiting column 1104 simultaneously enters the limiting column holes on the steel cable seat 21 and the fixing seat 22, and the steel cable seat 21 and the fixing seat 22 are quickly connected and fixed through the limiting column 1104. The operation is simple and the installation is convenient.

The guide tube 237 is movably connected to the surface of the cable seat 21 and is located at one side of the bottom of the guide tube 237. One end of the slide seat 238 penetrates into the guide tube 237 and is fixedly connected with a conical seat 239. The conical seat 239 is slidably connected to the inner wall of the guide tube 237, and its shape is adapted to the size of the conical groove inside the guide tube 237. The mounting holes 2310 are evenly opened on the surface of the conical portion of the conical seat 239. The bead 2311 is slidably connected to the inner wall of the mounting hole 2310. The synchronous extrusion rod 2312 is horizontally slidably connected to the surface of the cable seat 21. One end of the synchronous extrusion rod 2312 is threadedly connected to the cable. One end of the screw rod 2313 on the surface of the seat 21 is rotatably connected, and the other end of the synchronous extrusion rod 2312 is provided with a tapered portion and horizontally slidably connected in the tapered groove on the surface of the slide seat 238. The outer gear 2314 is symmetrically rotatably connected to the surface of the cable seat 21 and fixedly connected to one end of the central axis of the winding wheel 231. The middle gear 2315 is rotatably connected to the surface of the cable seat 21 and is located between the two groups of outer gears 2314. The middle gear 2315 is respectively meshed with the two groups of outer gears 2314. The adjustment handle 2316 is fixedly connected to the surface of the upper group of outer gears 2314. One end of the two sets of steel cables 31 are respectively wound and fixed on the surface of the two sets of winding wheels 231, and the other ends of the two sets of steel cables 31 are guided by the adjustment seat 235 and the guide wheel 236, pass through the outside of the conical seat 239 and the guide cylinder 237, and are fixedly connected with the connecting ring 30, and the connecting ring 30 is connected to the quick connection mechanism 24.

[0034] It should be noted that the surface of the adjustment seat 235 described in this embodiment is provided with a guide hole, and the bottom of the guide cylinder 237 is provided with a strip groove.

[0035] Specifically, the structure and connection relationship of the winding and fixing mechanism 23 are further explained. The winding and fixing mechanism 23 realizes efficient, flexible and stable control and fixation of the steel cable 31. Through the meshing relationship between the outer gear 2314, the middle gear 2315 and the adjusting handle 2316, the synchronous rotation of the winding wheel 231 and the rapid winding and release of the steel cable 31 are realized. Through the cooperation of the synchronous gear 232, the side gear 233, the reciprocating screw rod 234, the guide wheel 236, the conical seat 239 and the guide cylinder 237, the winding position and the exit position of the steel cable 31 can be flexibly controlled. Through the cooperation of the sliding seat 238, the mounting hole 2310, the card bead 2311, the synchronous extrusion rod 2312 and the screw rod 2313, the steel cable 31 can be flexibly fixed to prevent it from sliding or falling off due to external force.

[0036] When in use, one end of the steel cable 31 is wound and fixed on the surface of the winding wheel 231, and the other end is guided by the adjustment seat 235 and the guide wheel 236, passes through the outside of the conical seat 239 and the guide cylinder 237, and is fixedly connected with the connecting ring 30. The connecting ring 30 is connected to the quick connection mechanism 24 to realize the quick connection and fixation of the steel cable 31.

[0037] By turning the adjustment handle 2316, the outer gear 2314 is driven to rotate. Since the middle gear 2315 is meshed with the two sets of outer gears 2314, the two winding wheels 231 can be driven to rotate synchronously to achieve synchronous winding and release of the two sets of steel cables 31. The reciprocating screw rod 234 can rotate with the rotation of the winding wheel 231 through the meshing relationship between the side gear 233 and the synchronous gear 232, thereby driving the adjustment seat 235 to slide horizontally on the inner wall of the steel cable seat 21 and the surface of the reciprocating screw rod 234, thereby adjusting the winding position of the steel cable 31. The sliding seat 238 and the conical seat 239 can change the position of the conical seat 239 in the guide cylinder 237 by adjusting the synchronous extrusion rod 2312 and the screw rod 2313. The card bead 2311 is squeezed by the inner wall of the conical groove inside the guide cylinder 237 and slides on the inner wall of the mounting hole 2310, which can fix the steel cable 31 inside the conical seat 239 to prevent it from sliding due to vibration or external force.

[0038] In one embodiment of the present invention, Fig. 9As shown, the quick connection mechanism 24 includes an upper guide column 241, a lower guide column 242, a ring 243 and a spring 244. An L-shaped groove 221 is opened at the surface of the fixed seat 22 corresponding to the position of the quick connection mechanism 24. The upper guide column 241 is symmetrically fixedly connected to the top wall of the L-shaped groove 221, and the lower guide column 242 is symmetrically fixedly connected to the bottom wall of the L-shaped groove 221 and corresponds to the position of the upper guide column 241. A set spacing is set between the upper guide column 241 and the lower guide column 242 for the connecting ring 30 on one end surface of the steel cable 31 to pass through. The ring 243 is vertically slidably connected to the surface of the upper guide column 241, and a spring 244 is fixedly connected to the surface of the upper guide column 241. One end of the ring 243 is sleeved on the outside of the lower guide column 242 and is in contact with the top of the connecting ring 30.

[0039] Specifically, the structure and connection relationship of the quick-connect mechanism 24 are further explained. The quick-connect mechanism 24 is designed for quickly and easily connecting and fixing the steel cable 31 with the connecting ring 30. Compared with traditional operations, the design of the quick-connect mechanism 24 makes the installation process very simple and intuitive, and the operator does not need to have complex skills or knowledge to complete the installation. Due to the simplified installation process, the quick-connect mechanism 24 can significantly improve work efficiency, which is particularly important in large-scale installations or emergency situations. When the steel cable 31 needs to be replaced, the quick-connect mechanism 24 allows the operator to quickly and easily disconnect and replace the new steel cable 31, which reduces replacement time and improves equipment availability. The design of the quick-connect mechanism 24 also ensures a stable connection between the steel cable 31 and the fixing seat 22. This stability is crucial to ensuring the safety and reliability of the equipment. The quick-connect mechanism 24, with its unique structure and connection relationship, provides an efficient and simple solution for the quick connection and fixation of the steel cable 31, which not only reduces the difficulty of installation and improves work efficiency, but also facilitates the subsequent replacement of the steel cable 31 and ensures the safety and reliability of the equipment.

[0040] When in use, lift the ring 243 upward, the ring 243 moves up to expose the gap between the upper guide column 241 and the lower guide column 242, and compress the spring 244, then put the connecting ring 30 on the lower guide column 242 from the gap, and then release the ring 243, the ring 243 is reset under the elastic force of the spring 244, and is re-put on the lower guide column 242, and abuts against the top of the connecting ring 30.

[0041] In one embodiment of the present invention, Figure 1-Figure 3As shown, the surfaces of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are all provided with drawers 100, and are located on the top side of the installation cavity 15. The surfaces of the second frame 12, the third frame 13 and the fourth frame 14 are respectively provided with grooves 200, and are located between the drawers 100 and the installation cavity 15. The surfaces of the outer frame 111 and the elastic limiter 112 are respectively provided with fixing rings 300. The outer frame 111 is fixedly connected to the ground through the fixing bolt 400 and the fixing ring 300. A handle portion 500 is provided at one end of the outer frame 111 away from the lower end surface of the first frame body 11, and a tightening handle 600 is provided on the handle portion 500. The outer frame 111 is fixedly connected to the top of the first frame body 11 by tightening the handle 600. Arc grooves 700 are respectively provided on the surfaces of the first frame body 11, the second frame body 12 and the third frame body 13 at positions corresponding to the positions of the cross brace 18. A card slot is provided on the inner wall of the installation cavity 15 at positions corresponding to the positions of the elastic card member 19, and the elastic card member 19 is fixedly connected to the card slot.

[0042] It should be noted that the drawer 100 described in this embodiment is provided with a lock.

[0043] Specifically, the design of the drawer 100 allows key components such as the cable seat 21, the fixing seat 22 and the cross elastic connecting belt 34 to be transported together with the bracket assembly 1, which not only simplifies the transportation process, but also ensures that all necessary materials can arrive at the installation site together with the bracket assembly 1, effectively preventing the loss of materials. The pull groove 200 provides a clear force point, so that the frame can be pulled out more easily. This design improves the convenience of operation, especially when the frame position needs to be moved or adjusted. The foldable design of the fixing ring 300 not only prevents damage caused by impact when not in use, but also facilitates the stacking and storage of materials. This design improves space utilization and ensures that the fixing ring 300 can be quickly unfolded when needed, and the outer frame 111 can be quickly fixed by cooperating with the fixing bolt 400. The design of the handle 500 makes it easier to lift and lower the outer frame 111, which not only reduces the physical strength of the operator The design of tightening the handle 600 allows the outer frame 111 to be fixedly connected to the top of the first frame 11, thereby reducing the overall volume. This design makes the entire structure more compact and convenient for transportation and storage. The arc groove 700 provides a movable space for the cross brace 18, so that the frame can be freely retracted into the installation cavity 15. This design not only improves the flexibility of the structure, but also ensures that the frame can fit tightly with the inner wall of the installation cavity 15 after retraction. The slots opened at the inner wall of the installation cavity 15 corresponding to the position of the elastic clip 19 ensure that the frame can be fixed after retracting into the installation cavity 15. This design improves the stability of the structure and prevents the frame from accidentally moving during transportation or use. The design that the elastic force of the elastic clip 19 is less than the pulling force ensures that the frame can be easily pulled out. This design ensures the convenience of operation and prevents the difficulty of operation caused by excessive elastic force.

[0044] Through a series of ingenious functional and structural designs, convenience and efficiency are achieved during transportation, installation and use. The drawer 100, the pull groove 200, the fixing ring 300, the handle 500, the tightening handle 600, the arc groove 700, and the card slot and the elastic card 19 cooperate to form a bracket assembly 1 system that is both practical and efficient. This design not only improves operational efficiency, but also ensures the stability and safety of the structure, providing strong support for the installation of equipment such as photovoltaic panels.

[0045] In one embodiment of the present invention, Figure 1 As shown, the steel cables 31 on the first frame 11 , the second frame 12 , the third frame 13 and the fourth frame 14 are all arranged along the same oblique line.

[0046] Specifically, first, when both the large photovoltaic panel and the small photovoltaic panel need to be installed at a specific angle, the use of the steel cables 31 arranged along the same oblique line can ensure that they can all reach the required tilt angle. This design allows the photovoltaic panel to receive sunlight at the best angle, thereby improving the conversion efficiency of solar energy. Secondly, the arrangement of the same oblique line simplifies the installation process because the installer only needs to follow a clear path to install the steel cables 31 and the photovoltaic panel. This design reduces the possibility of installation errors because all photovoltaic panels follow the same tilt angle. Finally, by optimizing the installation angle of the photovoltaic panel, the absorption of solar energy can be maximized, thereby improving the power generation efficiency of the entire photovoltaic system. In addition, this design also helps to reduce damage to the photovoltaic panels caused by environmental factors such as wind and snow because they are all firmly installed on the same oblique line. The design of arranging multiple groups of steel cables 31 along the same oblique line not only ensures that the photovoltaic panels can be installed at the set angle, improves the conversion efficiency of solar energy, but also enhances the practicality and use effect of the system. This design simplifies the installation process, reduces installation errors, and helps protect the photovoltaic panels from damage by environmental factors.

[0047] In summary, the embodiment of the present invention is a flexible fixed bracket for a photovoltaic power station. The bracket assembly 1 of the present invention can be directly installed on the ground without the need for lifting operations, which greatly reduces the installation cost and safety risks. The folding ladder design not only simplifies the photovoltaic panel angle adjustment steps and ensures that the preset angle is reached after installation, but also has a small volume after folding, which is convenient for transportation, and can flexibly adjust the number of unfolded frames according to the size of the photovoltaic panel. In addition, the steel cable 31 is integrated in the connecting seat assembly 2 to achieve quick connection and fixation, and abandons the cumbersome bolt and arc-shaped sheet fixing method. During maintenance, only the connecting seat assembly 2 needs to be quickly disassembled, and the modular design makes maintenance more convenient and efficient.
