Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation components, and specifically relates to a light-tracking photovoltaic support. Background Art

[0002] With the continuous development of renewable energy technologies, photovoltaic power generation, as a clean and renewable energy form, has received extensive attention and applications. In a photovoltaic power generation system, the photovoltaic support, as a key component for supporting photovoltaic panels, its performance and stability are directly related to the power generation efficiency and safety of the entire system.

[0003] Chinese Patent CN218734013U discloses a photovoltaic installation support and its cable collection device, which relates to the technical field of photovoltaic installation components, including an installation support. A support leg is fixedly connected to the bottom end of the installation support, a fixed support is fixedly connected to the top of the installation support, and a cable collection device is fixedly connected to the bottom of the front end of the installation support. Through the mutual cooperation among the fixed frame, the top block, the driving rod, the first bevel gear, the second bevel gear, the threaded rod, the threaded slider, the push rod, and the fixed clamping plate, the photovoltaic panel is placed inside the fixed frame. By rotating the driving rod, the first bevel gear can drive the second bevel gear to rotate, and the threaded rod can drive the threaded slider to move. Thus, the fixed clamping plate can be pushed out by the push plate and clamped on the side of the photovoltaic panel, which can fix the photovoltaic panel, improve the fixing effect on the photovoltaic panel, and facilitate the installation of the photovoltaic panel.

[0004] The above device realizes the storage of cables through the cable collection device. However, in recent years, in order to improve the power generation efficiency of photovoltaic panels, light-tracking photovoltaic supports have emerged. The light-tracking photovoltaic support can automatically adjust the angle and orientation of the photovoltaic panel according to the real-time position of sunlight, so as to capture sunlight to the maximum extent and improve the power generation efficiency. In practical applications of the light-tracking photovoltaic support, one important problem is the collection and management of cables. Since the light-tracking photovoltaic support needs to adjust the position and angle of the photovoltaic panel in real time, the cables connected to the photovoltaic panel will also continuously change in length as the photovoltaic panel moves. Although the above cable collection device can realize the storage of cables to a certain extent, it cannot adaptively adjust the length of the cables to adapt to the real-time movement of the photovoltaic panel. When the photovoltaic panel adjusts its position as the sunlight moves, if the reserved length of the cable is too short, it may limit the movement range of the photovoltaic panel and even cause the cable to be pulled off; if the reserved length of the cable is too long, too many cables will accumulate in the collection device, affecting the storage effect and aesthetics, and at the same time, it may also increase the risk of the cable being entangled or damaged. In addition, since the light-tracking photovoltaic support is usually installed in an outdoor environment, the cables are exposed to sunlight and wind and rain for a long time, and are also prone to damage and aging. Summary of the Invention

[0005] To solve the above problems, a light-tracking photovoltaic bracket is provided. Through the adaptive collection device, the risk of cable winding or damage can be effectively reduced, and comprehensive cable protection performance can be achieved.

[0006] To solve the problems of the existing technology, the present invention provides a light-tracking photovoltaic bracket, which includes an adaptive collection device installed beside the light-tracking photovoltaic bracket. The adaptive collection device includes a guiding wire-passing shell. One end of the guiding wire-passing shell has an inlet, and the end of the guiding wire-passing shell away from the inlet is provided with an outlet. The inlet and the outlet provide a path for the cable to pass through the guiding wire-passing shell. A fixed cable-winding mechanism for winding the cable is installed inside the guiding wire-passing shell. An adaptive pulling-back mechanism is installed beside the fixed cable-winding mechanism. The adaptive pulling-back mechanism has a movable end that extends and retracts outside the outlet, and the movable end of the adaptive pulling-back mechanism is fixedly connected to the cable.

[0007] Preferably, the adaptive pulling-back mechanism includes a folding and distributing component installed inside the guiding wire-passing shell. The folding and distributing component is used for folding and distributing the cable. A pulling and rebounding mechanism is installed beside the folding and distributing component, and the movable end of the pulling and rebounding mechanism is fixedly connected to the cable.

[0008] Preferably, the folding and distributing component is composed of a plurality of elastic pressing mechanisms. Each elastic pressing mechanism is provided with a guiding roller that can move elastically. The plurality of elastic pressing mechanisms are divided into two groups. The elastic pressing mechanisms in each group are evenly spaced, and the two groups of elastic pressing mechanisms are distributed in a relative and staggered state.

[0009] Preferably, the pulling and rebounding mechanism includes a pulling-back component with a reset and stretching function. The pulling and rebounding mechanism further includes a plurality of assembling and fixing parts, and the plurality of assembling and fixing parts are connected to the pulling-back component through a winding strip.

[0010] Preferably, the assembling and fixing part is assembled by a connecting sleeve and a pressing sleeve. A clamping port for clamping and fixing the cable is provided between the connecting sleeve and the pressing sleeve.

[0011] Preferably, the fixed cable-winding mechanism includes a rotating cable-winding shaft installed on the guiding wire-passing shell. A wire-passing channel is provided on the rotating cable-winding shaft, and the wire-passing channel is used to provide a wire-passing path.

[0012] Preferably, the fixed cable-winding mechanism further includes an auxiliary cable-winding bracket installed inside the guiding wire-passing shell. A plurality of elastically telescopic pressing rollers are provided on the auxiliary cable-winding bracket. The pressing rollers approach the outer wall of the rotating cable-winding shaft, and the pressing rollers are used to assist in pressing the cable on the rotating cable-winding shaft.

[0013] Preferably, a detachable limit cover plate is provided on the side of the guiding wire-passing shell. A limit frame is provided on the inner side of the limit cover plate, and the limit frame is used to press the cable inside the guiding wire-passing shell.

[0014] Preferably, the adaptive collection device further includes a wiring sleeve sleeved outside the cable.

[0015] Preferably, several folding marks are provided on the outer side of the wiring sleeve, and several air holes are also provided on the outer side of the wiring sleeve.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. By integrating the adaptive collection device, the present invention realizes the adaptive length adjustment of the cable. The fixed winding mechanism and the adaptive pulling-back mechanism inside the adaptive collection device work together, and can release or recycle the cable in real time according to the change requirements of the cable length when the photovoltaic panel moves. It ensures that the cable always maintains an appropriate tension and distribution state during the movement of the photovoltaic panel, avoiding both excessive accumulation or slack of the cable and ensuring that the photovoltaic panel can move freely to capture sunlight to the maximum extent. This not only improves the flexibility and stability of the photovoltaic support system, but also optimizes the cable storage effect and aesthetics, while reducing the risk of the cable being entangled or damaged.

[0017] 2. By introducing the wiring sleeve and the wiring buckle, the present invention provides comprehensive protection for the cable. The wiring sleeve is made of wear-resistant and corrosion-resistant materials, tightly wraps the cable, effectively reduces the direct contact area between the cable and the external environment, thereby reducing the aging speed of the cable caused by factors such as ultraviolet radiation. At the same time, the wiring sleeve also has certain insulation performance, which can prevent the cable from short-circuiting or being damaged due to accidental contact. The wiring buckle fits tightly with the wiring sleeve, provides stable guidance for the wiring sleeve, and can support the wiring sleeve to a certain extent, reducing the sag of the cable caused by its own weight or external tension. This comprehensive cable protection design ensures the normal operation of the photovoltaic support system and the long service life of the cable, and improves the reliability and safety of the entire system.

[0029] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] See Figures 1 to 10As shown in the figure, a light-tracking photovoltaic support includes an adaptive collection device installed beside the light-tracking photovoltaic support. The adaptive collection device includes a guiding wire threading housing 3. One end of the guiding wire threading housing 3 has an inlet 31, and the end of the guiding wire threading housing 3 away from the inlet 31 is provided with an outlet 32. The inlet 31 and the outlet 32 provide a path for the cable 5 to pass through the guiding wire threading housing 3. A fixed cable winding mechanism 2 for winding the cable 5 is installed inside the guiding wire threading housing 3. An adaptive retraction mechanism 1 is installed beside the fixed cable winding mechanism 2. The adaptive retraction mechanism 1 has a movable end that extends outside the outlet 32, and the movable end of the adaptive retraction mechanism 1 is fixedly connected to the cable 5.

[0031] In the initial installation stage, the staff passes one end of the cable 5 through the guiding wire threading housing 3 and adjusts the length of the cable 5 as needed. The excess unused part of the cable 5 is wound and stored by driving the fixed cable winding mechanism 2, while the part of the cable 5 that needs to be used immediately remains extended and is connected to the photovoltaic panel. The adaptive retraction mechanism 1 pre-stores a certain length of cable 5 that can be actively pulled out to adapt to the change in the length of the cable 5 when the photovoltaic panel moves.

[0032] When the light-tracking photovoltaic support adjusts the angle and orientation of the photovoltaic panel according to the real-time position of the sun, the length of the connected cable 5 will change accordingly. When the cable 5 is stretched, the adaptive retraction mechanism 1 can synchronously release the pre-stored cable 5 to ensure that the cable 5 can smoothly extend following the movement of the photovoltaic panel. When the light-tracking photovoltaic support resets or the photovoltaic panel moves to a new position, the adaptive retraction mechanism 1 will retract the cable 5 to keep the cable 5 in a proper tension and distribution state, avoiding excessive accumulation or slack of the cable 5.

[0033] In this way, the adaptive collection device can adaptively adjust the length of the cable 5 to meet the real-time movement requirements of the photovoltaic panel. This not only ensures that the photovoltaic panel can move freely to capture sunlight to the maximum extent, but also guarantees the storage effect and aesthetics of the cable 5, while reducing the risk of the cable 5 being entangled or damaged. In addition, due to the presence of the adaptive collection device, the exposure degree of the cable 5 in the outdoor environment is effectively controlled, thereby extending the service life of the cable 5.

[0034] The light-tracking photovoltaic support is an existing technology and will not be elaborated here.

[0035] See Figures 2 to 4 As shown in the figure, the adaptive retraction mechanism 1 includes a folding and distributing component 11 installed inside the guiding wire threading housing 3. The folding and distributing component 11 is used for folding and distributing the cable 5. A pulling and rebounding mechanism 12 is installed beside the folding and distributing component 11. The movable end of the pulling and rebounding mechanism 12 is fixedly connected to the cable 5.

[0036] The adaptive retraction mechanism 1 includes a folding and distributing component 11 and a pulling and rebounding mechanism 12. The folding and distributing component 11 is installed inside the guiding wire threading housing 3 and is used for folding and distributing the cable 5, effectively increasing the storage length of the cable 5. The movable end of the pulling and rebounding mechanism 12 is fixedly connected to the extended cable 5.

[0037] When the light-tracking photovoltaic support adjusts the angle and orientation of the photovoltaic panel according to the real-time position of the sun, the length of the cable 5 connected thereto will change accordingly. When the cable 5 is stretched, it will drive the movable end of the pulling and rebounding mechanism 12 to stretch and move synchronously. At this time, the folding and distributing component 11 is affected by the pulling and releases the pre-stored cable 5 synchronously to ensure that the cable 5 can smoothly extend following the movement of the photovoltaic panel.

[0038] When the light-tracking photovoltaic support resets, the pulling and rebounding mechanism 12 will rebound, driving the cable 5 to contract towards the inside of the guiding wire threading housing 3. The cable 5 that contracts and enters is then refolded and stored by the folding and distributing component 11, keeping the cable 5 in a proper tension and distribution state and avoiding excessive accumulation or slack of the cable 5.

[0039] The adaptive collection device can adaptively adjust the length of the cable 5 to meet the real-time movement requirements of the photovoltaic panel.

[0040] See Figure 4 、 Figure 8 and Figure 9 As shown in

[0041] The folding and distributing component 11 is composed of a plurality of elastic pressing mechanisms 111. Each elastic pressing mechanism 111 is provided with a guiding roller 114 that can move elastically. The plurality of elastic pressing mechanisms 111 are divided into two groups. The elastic pressing mechanisms 111 in each group are evenly spaced, and the two groups of elastic pressing mechanisms 111 are distributed in a relative and staggered state.

[0042] The gap between the two groups of elastic pressing mechanisms 111 forms a folding wiring track. The elastic pressing mechanism 111 includes an internal mounting base 112 fixedly installed in the guiding wire threading housing 3. A first telescopic bracket 113 is slidably installed on the mounting base 112. A guiding roller 114 is installed on the first telescopic bracket 113. A first spring 115 is installed between the first telescopic bracket 113 and the mounting base 112, and the first spring 115 is used to provide an elastic pressing force for the first telescopic bracket 113.

[0043] The elastic pressing mechanism 111 is divided into two groups. The elastic pressing mechanisms 111 in each group are evenly spaced, and the two groups of elastic pressing mechanisms 111 are distributed in a relative and staggered state. This layout forms a folded wiring track between the two groups of elastic pressing mechanisms 111, and the folded wiring track provides an orderly folding path for the cable 5. Each elastic pressing mechanism 111 is composed of a mounting base 112 fixedly installed inside the guiding wire passing housing 3, a first telescopic bracket 113 slidably installed on the mounting base 112, and a first spring 115 connected between the first telescopic bracket 113 and the mounting base 112. The first spring 115 provides an elastic pressing force for the first telescopic bracket 113, so that the guiding roller 114 can maintain an appropriate pressure on the cable 5, thereby realizing the elastic folding of the cable 5.

[0044] When the light-tracking photovoltaic support adjusts the angle and orientation of the photovoltaic panel according to the real-time position of the sun, the length of the cable 5 connected thereto will change accordingly. When the cable 5 is stretched, it will drive the movable end of the pulling and rebounding mechanism 12 to stretch and move synchronously. At this time, the elastic pressing mechanism 111 in the folding distribution assembly 11 will be affected by the stretching of the cable 5, and the first telescopic bracket 113 will adaptively contract, thereby releasing the pre-stored cable 5 to ensure that the cable 5 can smoothly extend following the movement of the photovoltaic panel.

[0045] When the light-tracking photovoltaic support resets, the pulling and rebounding mechanism 12 will rebound, driving the cable 5 to contract towards the inside of the guiding wire passing housing 3. As the cable 5 contracts, the first spring 115 will push the first telescopic bracket 113 to rebound and reset. During the reset process, the guiding roller 114 will push the cable 5 to fold along the folded wiring track, thereby realizing the re-folding and storage of the cable 5. It ensures that the cable 5 can be effectively folded and stored inside the guiding wire passing housing 3 when the pulling force is lost, avoiding excessive accumulation or slack of the cable 5.

[0046] See Figure 4 and Figure 5 As shown in

[0047] The pulling and rebounding mechanism 12 includes a pulling-back component with a reset and stretching function. The pulling and rebounding mechanism 12 also includes a plurality of assembling and fixing parts 124, and the plurality of assembling and fixing parts 124 are connected to the pulling-back component through a winding strip 123.

[0048] During the process of the photovoltaic support adjusting the angle and orientation of the photovoltaic panel according to the sunlight position, the cable 5 connected thereto will experience a change in length. When the cable 5 is subjected to a tensile force, it will pull the assembled fixing part 124 to move accordingly. The movement of the assembled fixing part 124 further drives the winding strip 123 to stretch. The stretching action of the winding strip 123 causes the coil spring 122 to be stretched and simultaneously contract and compress, thereby generating a resilience force. During this process, the series structure of multiple assembled fixing parts 124 and the winding strip 123 ensures the stability of the cable 5 during stretching and moving.

[0049] When the photovoltaic support and the photovoltaic panel are reset and no longer apply a tensile force to the cable 5, the resilience force accumulated by the coil spring 122 begins to be released, driving the winding strip 123 to contract and move. The contraction of the winding strip 123, through the cooperation of multiple assembled fixing parts 124, guides the cable 5 to contract and reset inside the guiding wire threading housing 3. At the same time, the folding distribution component 11 synchronously releases or accommodates the cable 5 during the stretching and contraction of the cable 5 to adapt to the change in the length of the cable 5 and ensure that the cable 5 maintains an appropriate tension and distribution state inside the guiding wire threading housing 3.

[0050] See Figure 5 and Figure 6 As shown, the assembled fixing part 124 is assembled by a connecting sleeve 1241 and a pressing sleeve 1244. There is a clamping opening 1246 for clamping and fixing the cable 5 between the connecting sleeve 1241 and the pressing sleeve 1244.

[0051] On both sides of the connecting sleeve 1241, there are docking slots 1242. Inside the docking slots 1242, there are evenly arranged clamping protrusions 1243. On both sides of the pressing sleeve 1244, there are installation buckles 1245. The inner walls of the clamping opening 1246 are anti-slip contact surfaces, and the anti-slip contact surfaces are used to increase the friction force in contact with the outer wall of the cable 5.

[0052] The clamping protrusions 1243 of the connecting sleeve 1241 cooperate with the installation buckles 1245 on the pressing sleeve 1244 during the assembly process to form a firm clamping structure. This ensures the stable installation of the assembled fixing part 124 on the cable 5 and prevents the assembled fixing part 124 from falling off or loosening during the movement of the cable 5.

[0053] The pressing sleeve 1244 is installed by the installation buckles 1245 on both sides cooperating with the docking slots 1242 of the connecting sleeve 1241. During the installation process, the user only needs to align the buckle part of the pressing sleeve 1244 with the slot of the connecting sleeve 1241 and apply appropriate pressure to make the buckle closely cooperate with the clamping protrusions 1243 in the slot, thereby realizing the assembly of the assembled fixing part 124.

[0054] The clamping opening 1246 is located between the connecting ferrule 1241 and the pressing ferrule 1244. The anti-slip contact surface on the inner wall of the clamping opening 1246 increases the frictional force in contact with the outer wall of the cable 5, thus ensuring that the cable 5 is firmly fixed within the clamping opening 1246. Even when the cable 5 is subjected to tensile or contraction forces, the anti-slip design of the clamping opening 1246 can effectively prevent the cable 5 from slipping or displacing.

[0055] Through the ingenious design of the connecting ferrule 1241 and the pressing ferrule 1244 of the assembled fixing part 124, as well as the anti-slip contact surface of the clamping opening 1246, the stable fixation of the cable 5 is achieved. It not only improves the stability of the cable 5 during the stretching and contraction processes, but also facilitates the installation and maintenance by the user. During the process of adjusting the angle and orientation of the photovoltaic panel according to the sunlight position by the photovoltaic bracket, the assembled fixing part 124 provides a reliable fixed connection point for the winding strip 123.

[0056] See Figure 2 、 Figure 4 and Figure 7 As shown in

[0057] The rotating winding shaft 21 of the fixed winding mechanism 2 is rotatably connected to the guiding wire passing housing 3. A winding handle 212 is also installed on the rotating winding shaft 21, and the winding handle 212 facilitates the staff to drive the rotation of the rotating winding shaft 21.

[0058] The rotating winding shaft 21 is designed with a wire guiding channel 211, which provides a clear wire passing path for the cable 5. The inlet end of the wire guiding channel 211 is located on the outer wall of the rotating winding shaft 21, and the outlet end is arranged at the axial center position of the rotating winding shaft 21. Such a design ensures that the cable 5 can enter from the inlet 31 of the guiding wire passing housing 3, pass through the wire guiding channel 211 on the rotating winding shaft 21, and finally pass out from the outlet 32 and enter the adaptive pulling-back mechanism 1.

[0059] In order to drive the rotation of the rotating winding shaft 21 to wind the redundant cable 5 when needed, a winding handle 212 is also installed on the rotating winding shaft 21. The design of the winding handle 212 facilitates the manual operation by the staff, and the rotation of the rotating winding shaft 21 is driven by applying a torque.

[0060] In actual operation, if there is excess cable 5 to be wound up, the operator can drive the rotating winding shaft 21 to rotate by operating the winding handle 212. As the rotating winding shaft 21 rotates, the cable 5 is gradually wound onto the rotating winding shaft 21 until the required winding degree is reached. Through this process, the excess cable 5 is effectively fixed and stored on the rotating winding shaft 21, which not only keeps the cable 5 tidy but also avoids excessive exposure of the cable 5 in the outdoor environment, thereby extending the service life of the cable 5.

[0061] See Figure 4 and Figure 7 As shown, the fixed winding mechanism 2 further includes an auxiliary winding bracket 22 installed inside the guiding wire housing 3. A plurality of elastically telescopic pressing rollers 221 are provided on the auxiliary winding bracket 22. The pressing rollers 221 approach the outer wall of the rotating winding shaft 21, and the pressing rollers 221 are used to assist in pressing the cable 5 on the rotating winding shaft 21.

[0062] The auxiliary winding bracket 22 further includes a plurality of second telescopic brackets 222. The second telescopic brackets 222 are slidably connected to the auxiliary winding bracket 22. A second spring 223 is provided between the second telescopic brackets 222 and the auxiliary winding bracket 22. The extending end of the second telescopic bracket 222 is connected to the pressing roller 221.

[0063] The function of the second spring 223 is to push the second telescopic bracket 222 to perform elastic telescopic movement. The extending end of the second telescopic bracket 222 is connected to the pressing roller 221. Through the pushing action of the second spring 223, it is ensured that the pressing roller 221 can elastically press the cable 5.

[0064] When the rotating winding shaft 21 rotates to wind up the excess cable 5, the cable 5 will be pressed by the pressing roller 221, thereby ensuring that the cable 5 can be neatly and tightly wound around the outside of the rotating winding shaft 21. The winding effect of the cable 5 is effectively improved, ensuring that the wound cable 5 is both neat and compact, and avoiding the possible loosening or irregularity of the cable 5 during the winding process.

[0065] See Figures 1 to 5 As shown, a detachable limit cover plate 33 is provided on the side of the guiding wire housing 3. A limit frame 331 is provided on the inner side of the limit cover plate 33, and the limit frame 331 is used to press the cable 5 inside the guiding wire housing 3.

[0066] A plurality of sliding rollers 321 are installed at the wire outlet 32 of the guiding wire housing 3 to reduce the frictional resistance between the cable 5 and the edge of the wire outlet 32 during the telescopic process.

[0067] During the cable 5 threading process, the staff first removes the limit cover 33 to facilitate the arrangement and threading of the cable 5. After the cable 5 passes smoothly through the internal channel of the guide threading housing 3, the staff resets and installs the limit cover 33. At this time, the limit frame 331 structure inside the limit cover 33 will tightly fit and press the cable 5, ensuring that the cable 5 maintains a stable arrangement and distribution inside the guide threading housing 3, and at the same time forms a good connection and cooperation with the fixed winding mechanism 2 and the adaptive pull-back mechanism 1.

[0068] The sliding roller 321 at the cable outlet 32 ​​further reduces the friction resistance of the cable 5 during the extension and retraction action by means of rolling contact, thereby improving the smoothness and efficiency of the movement of the cable 5 .

[0069] See also Figure 1 As shown, the adaptive collecting device further comprises a wiring sleeve 4 which is sleeved on the outside of the cable 5 .

[0070] A plurality of wiring buckles 41 are installed on the outside of the wiring sleeve 4. The wiring sleeve 4 is used to be sleeved on the cable 5 exposed to the outside of the guide wire housing 3 to protect the cable 5 from damage by the external environment. The wiring sleeve 4 is made of wear-resistant and corrosion-resistant materials to ensure that the cable 5 is effectively protected. The wiring sleeve 4 extends along the length direction of the cable 5, wraps the cable 5, reduces the direct contact area between the cable 5 and the external environment, and thus reduces the aging speed of the cable 5 due to ultraviolet radiation. In addition, the wiring sleeve 4 also has certain insulation properties, which can effectively prevent the cable 5 from short circuiting or damage caused by accidental touch. On the outside of the wiring sleeve 4, multiple wiring buckles 41 are evenly distributed. The wiring buckle 41 is made of sturdy and durable materials, and the wiring buckle 41 can fit the wiring sleeve 4 tightly and provide stable guidance for the wiring sleeve 4. At the same time, the wiring buckle 41 can also support the wiring sleeve 4 to a certain extent, reduce the sagging phenomenon of the cable 5 caused by its own weight or external tension, maintain the straightness and tension of the cable 5, and ensure that the connection between the photovoltaic panel and the cable is stable and reliable. The wiring sleeve 4 tightly wraps the cable 5 and provides effective protection, and the wiring buckle 41 guides and supports the wiring sleeve 4 stably, which jointly realizes the comprehensive protection of the cable 5, ensuring the normal operation of the photovoltaic support system and the long-term service life of the cable 5.

[0071] See also Figure 1 and Figure 10 As shown, a plurality of folding marks 42 are provided on the outer side of the wiring sleeve 4 , and a plurality of air holes 43 are also provided on the outer side of the wiring sleeve 4 .

[0072] On the outer side of the wiring sleeve 4, there are also several folding marks 42. The design of the folding marks 42 enables the wiring sleeve 4 to be easily folded or bent when needed to adapt to the installation requirements in different scenarios. At the same time, the existence of the folding marks 42 also enhances the flexibility and durability of the wiring sleeve 4, making it less likely to be damaged or broken during use. In addition, several air holes 43 are provided on the outer side of the wiring sleeve 4. The main function of the air holes 43 is to balance the air pressure inside and outside the wiring sleeve 4 and prevent the expansion or contraction of the wiring sleeve 4 caused by air pressure differences. By reasonably setting the size and quantity of the air holes 43, it can be ensured that the wiring sleeve 4 always maintains a stable shape and performance during long-term use.

[0073] Specific working principle: In the initial installation stage, the staff passes one end of the cable 5 through the guiding wire threading shell 3 and adjusts the length of the cable 5 as needed. The redundant unused part of the cable 5 is wound and stored by driving the fixed winding mechanism 2, while the part of the cable 5 that needs to be used immediately remains extended and is connected to the photovoltaic panel. The adaptive pulling-back mechanism 1 pre-stores a certain length of the cable 5 that can be actively pulled out to adapt to the change in the length of the cable 5 when the photovoltaic panel moves.

[0074] When the light-tracking photovoltaic bracket adjusts the angle and orientation of the photovoltaic panel according to the real-time position of the sun, the cable 5 connected to it will change in length accordingly. When the cable 5 is stretched, the adaptive pulling-back mechanism 1 can synchronously release the pre-stored cable 5 to ensure that the cable 5 can smoothly extend following the movement of the photovoltaic panel. When the light-tracking photovoltaic bracket resets or the photovoltaic panel moves to a new position, the adaptive pulling-back mechanism 1 will pull back the cable 5 to keep the cable 5 in a proper tension and distribution state, avoiding excessive accumulation or slack of the cable 5.

[0075] In this way, the adaptive collection device can adaptively adjust the length of the cable 5 to meet the real-time movement requirements of the photovoltaic panel. This not only ensures that the photovoltaic panel can move freely to capture sunlight to the maximum extent, but also guarantees the storage effect and aesthetics of the cable 5, while reducing the risk of the cable 5 being entangled or damaged. In addition, due to the existence of the adaptive collection device, the exposure degree of the cable 5 in the outdoor environment is also effectively controlled, thus extending the service life of the cable 5.

[0076] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
