Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a retractable lighting structure for sports stadiums and its usage method. Background Technology

[0002] To ensure the lighting effect of stadiums or large buildings, openable light stands are usually used, on which a large number of chandeliers are installed. When lighting is needed, the light stands are unfolded and raised; when not in use, the light stands are closed to protect the chandeliers.

[0003] However, the existing light fixtures do not have any windproof devices when unfolded. When encountering strong winds, the closure of the light fixtures will be affected, and the light fixtures cannot protect the chandeliers from the wind, which poses a risk of the chandeliers falling and a certain safety hazard. Summary of the Invention

[0004] In view of this, the present invention discloses a structure and method for using a sports stadium opening and closing light frame, the purpose of which is to solve the problem that the existing light frames do not have a windproof structure, and the closing of the light frame is affected.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A retractable lighting structure for a sports stadium includes a support base fixed to the top of the building. A lighting frame is hinged to one end of the support base, and several pendant lights are installed on the lower end of the lighting frame. An adjustable push rod is hinged between the support base and the lighting frame. A control device for controlling the length change of the push rod is installed on the support base. Two guide rails symmetrically arranged about the support base are fixed to the upper end of the support base. A slide block is slidably arranged on each guide rail. A support rod is hinged between each slide block and the lighting frame. A limiting structure for restricting the sliding of the slide block is provided on the slide block. A protective structure is provided on the slide block. The protective structure includes recesses at both ends of the slide block facing the guide rail. A transmission rod facing the guide rail is horizontally rotatably connected to each recess. A torsion spring is provided between the transmission rod and the recess. A horizontally inclined brake rod is fixed on each transmission rod, and adjacent brake rods face opposite directions. Several brake blocks abutting against the transmission rod are evenly distributed on both sides of the guide rail. A foldable windproof structure is provided on the lighting frame.

[0007] When lighting is required, the limiting structure is released from the slide block, and the push rod is extended via the control device. The push rod pushes the lamp holder to deflect and lift. When the lamp holder is lifted, the support rod drives the slide block to slide along the guide rail until the lamp holder deflects to the required lighting angle. The push rod is then stopped extending via the control device. At this time, the limiting structure fixes the slide block to the guide rail, and the support rod provides auxiliary support for the lamp holder, enhancing the stability of the lamp holder structure. When the lamp holder encounters strong winds during use, the windproof structure is deployed to protect the chandelier and prevent it from falling during the closing process of the lamp holder.

[0008] Furthermore, when the lamp holder closes or unfolds, the slide slides relative to the guide rail, and the transmission rod on the slide abuts against the brake block, causing the transmission rod to deflect. The transmission rod then drives the brake rod to deflect synchronously. The brake rod on the opposite side of the slide's movement direction deflects away from the guide rail and never contacts the brake block, while the brake rod on the other side deflects closer to the guide rail. When the lamp holder closes or unfolds normally, the slide slides at a low speed relative to the guide rail. At this time, the brake rod is reset by the torsion spring before contacting the adjacent brake block, allowing the slide to slide normally. When the lamp holder closes or unfolds too quickly, the slide slides rapidly relative to the guide rail. At this time, the brake rod has not yet been reset by the torsion spring and is in contact with the adjacent brake block. Instead, the corresponding transmission rod abuts against the inner wall of the cavity, causing the brake rod to abut against the brake block, limiting the continued sliding of the slide and thus preventing the lamp holder from closing or unfolding too quickly, which could damage the lamp holder.

[0009] Furthermore, the windproof structure includes side wind deflectors respectively disposed on both sides of the lamp holder. Each side wind deflector has a parallel rotating shaft fixed to its top. The rotating shafts are rotatably connected to the corresponding side walls of the lamp holder. A driving device for driving the rotating shafts is disposed on the side walls of the lamp holder. A parallel slide rail is hinged to the bottom of each side wind deflector. Several connecting rods are horizontally and vertically disposed between the slide rails. Connecting seats are slidably disposed at both ends of each connecting rod along its axial direction. The connecting seats are slidably connected to the corresponding slide rails. A power device for driving the connecting seats to slide on the slide rails is disposed on each connecting seat. Windproof plates are hinged to both sides of each connecting rod, and adjacent windproof plates are hinged together. The length and width of the lamp holder are both greater than the support base, and the chandelier is disposed on the end of the lamp holder that extends beyond the support base.

[0010] When the light fixture is in its extended state and encounters strong winds, the drive mechanism rotates the shaft in the forward direction until it causes the side wind deflector to tilt vertically downwards. When the wind is directly facing the side wind deflector, it tilts downwards to prevent strong winds from hitting it directly and to prevent the light fixture from being subjected to lateral forces that could affect its rapid closure. As the side wind deflector unfolds, it causes the slide rail to move diagonally downwards, which in turn causes the connecting seat to slide relative to the connecting rod, causing the connecting rod to move downwards relative to the light fixture. After the side wind deflector unfolds, the power mechanism drives the connecting seat to slide the connecting rod along the slide rail, causing the windproof panels between the connecting rods to unfold. The side wind deflector and windproof panels effectively shield the chandelier, preventing it from falling due to strong winds. Furthermore, the unfolded windproof structure can also serve as a maintenance access point for the light fixture, allowing maintenance personnel to directly access the chandelier and perform maintenance in a safer manner.

[0011] After the strong wind subsides, the drive device drives the rotating shaft to deflect in the opposite direction until the rotating shaft drives the side wind deflector to fit against the lower end of the lamp holder. As the side wind deflector closes, it drives the slide rail to move diagonally upward, and the slide rail drives the connecting seat to slide relative to the connecting rod, causing the connecting rod to return to its original position. After the side wind deflector unfolds, the power device drives the connecting seat to drive the connecting rod to slide back to its original position along the slide rail, causing the windproof plate between the connecting rods to fold and reveal the chandelier.

[0012] Furthermore, mounting seats are symmetrically arranged on the end face of the windbreak plate, and a rotating shaft parallel to the windbreak plate is rotatably connected between the mounting seats. Several blades are fixed on the rotating shaft, and coaxial circular cavities are opened at both ends of the rotating shaft. Wavy annular grooves are opened on the periphery of the circular cavities. Hydraulic dampers facing the rotating shaft are fixed on the opposite end faces of the mounting seats. The output end of the hydraulic damper passes through the mounting seat and extends into the circular cavity. Several support rods extending into the annular grooves are fixed on the periphery of the output end of the hydraulic damper.

[0013] During the closing process of the light fixture, if the wind direction is directly facing the windbreak plate, the wind blows towards the windbreak plate. At this time, the wind blows the blades and drives the rotating shaft to rotate. During the rotation of the rotating shaft, the support rod output by the hydraulic damper rotates continuously along the annular groove. Since the annular groove is wavy, the support rod continuously reciprocates along its axis during rotation, which in turn drives the hydraulic damper to dissipate hydraulic energy, preventing strong winds from blowing onto the lower end of the light fixture and giving the light fixture the kinetic energy to lift it, thus affecting the closing of the light fixture.

[0014] Furthermore, the limiting structure includes through holes formed on the slide, all of which face the guide rail. A telescopic rod is provided inside the through hole, and the guide rail is provided with a plurality of limiting holes that cooperate with the telescopic rod.

[0015] Furthermore, an auxiliary support structure is provided between adjacent connecting rods. The auxiliary support structure includes two support rods that are hinged to each other in the middle. Both ends of the support rods are hinged to supports, which are slidably connected to the adjacent connecting rods along their axial direction.

[0016] Furthermore, the side wind deflector is a telescopic structure.

[0017] Furthermore, a front windshield is provided on one end of the lamp holder that extends out of the support base.

[0018] A method for using a retractable lighting fixture structure for a sports stadium includes the following steps:

[0019] 1) Lamp holder opening: When lighting is required, the telescopic rod is shortened and disengaged from the limiting hole, thereby releasing the limiting structure from the slide block. The push rod is then extended by the control device, pushing the lamp holder to deflect and lift. When the lamp holder is lifted, the slide block slides along the guide rail through the support rod until the lamp holder deflects to the required lighting angle. The push rod is then stopped by the control device. At this time, the telescopic rod is extended and inserted into the limiting hole. The limiting structure fixes the slide block to the guide rail, and the support rod provides auxiliary support for the lamp holder.

[0020] 2) Windproof Structure Deployment: In strong wind conditions, the drive device drives the rotating shaft to deflect until the shaft drives the side wind deflector to a vertical downward position. When the wind direction is directly opposite the side wind deflector, the side wind deflector tilts downward to prevent strong winds from directly hitting the side wind deflector and to prevent the lamp holder from being subjected to lateral forces, which would affect the lamp holder's rapid closure. As the side wind deflector deploys, it drives the slide rail to move diagonally downward. The slide rail then drives the connecting seat to slide relative to the connecting rod, causing the connecting rod to move downward relative to the lamp holder. After the side wind deflector is deployed, the power device drives the connecting seat to move the connecting rod along the slide rail, causing the windproof plate between the connecting rods to deploy. The side wind deflector, front wind deflector, and windproof plate effectively shield the chandelier, preventing the chandelier from falling due to strong winds.

[0021] 3) Lamp Stand Closure: The limiting structure restricts the slide block, and the push rod is shortened by the control equipment. The push rod drives the lamp stand to deflect and descend. When the lamp stand descends, the slide block slides along the guide rail through the support rod until the lamp stand closes. At this time, the limiting structure fixes the slide block on the guide rail, which plays a role in fixing the lamp stand. During the closure process, when the wind direction is directly facing the windproof plate, the wind blows the blades and drives the rotating shaft to rotate. During the rotation of the rotating shaft, the support rod at the output end of the hydraulic damper rotates continuously along the annular groove. Since the annular groove is wavy, the support rod continuously reciprocates along its axis during rotation, which in turn drives the hydraulic damper to dissipate hydraulic energy and prevent strong winds from blowing onto the lower end of the lamp stand, giving the lamp stand the kinetic energy to lift it and affecting the closure of the lamp stand. In addition, when the lamp stand is closed or unfolded, the slide block relative to the guide rail... When the slide rail slides, the transmission rod on the slide block abuts against the brake block, causing the transmission rod to deflect. The transmission rod then drives the brake rod to deflect synchronously. The brake rod on the opposite side of the slide block's direction of movement deflects to a position away from the guide rail, and this brake rod never contacts the brake block. Meanwhile, the brake rod on the other side deflects to a position closer to the guide rail. When the lamp holder closes or opens normally, the slide block slides at a low speed relative to the guide rail. At this time, the brake rod is reset by the torsion spring before contacting the adjacent brake block, allowing the slide block to slide normally. When the lamp holder closes or opens too quickly, the slide block slides rapidly relative to the guide rail. At this time, the brake rod has not yet been reset by the torsion spring before contacting the adjacent brake block. Instead, the corresponding transmission rod abuts against the inner wall of the cavity, causing the brake rod to abut against the brake block, limiting the continued sliding of the slide block and thus preventing the lamp holder from closing or opening too quickly, which could damage the lamp holder.

[0022] 4) Windproof structure closure: After the strong wind ends, the drive device drives the rotating shaft to deflect in the opposite direction until the rotating shaft drives the side wind deflector to fit against the lower end of the lamp holder; at the same time as the side wind deflector closes, it drives the slide rail to move obliquely upward, and the slide rail drives the connecting seat to slide relative to the connecting rod, causing the connecting rod to return to its original position synchronously; after the side wind deflector closes, the power device drives the connecting seat to drive the connecting rod to slide along the slide rail to return to its original position, so that the windproof plate between the connecting rods folds and exposes the chandelier.

Detailed Implementation

[0032] like Figures 1-5 As shown:

[0033] A retractable lighting fixture 2 structure for a sports stadium includes a support base 1 fixed to the top of the building. A lighting fixture 2 is hinged to one end of the support base 1, and several pendant lights 3 are mounted on the lower surface of the lighting fixture 2. An adjustable push rod 4 is hinged between the support base 1 and the lighting fixture 2. In this embodiment, the push rod 4 is a hydraulic push rod. A control device (a conventional technique for those skilled in the art, therefore not shown in the figure) is installed on the support base 1. The control device controls the length change of the push rod 4 by controlling the hydraulic pressure change. Two guide rails 5 are fixed to the upper end of the support base 1, symmetrically arranged about the support base 1. Sliding blocks 6 are slidably mounted on each guide rail 5, and support rods 7 are hinged between each sliding block 6 and the lighting fixture 2. The slide block 6 is provided with a limiting structure to restrict the sliding of the slide block 6; the slide block 6 is provided with a protective structure, the protective structure includes a cavity at both ends of the slide block 6 facing the guide rail 5, a transmission rod 24 facing the guide rail 5 is horizontally rotatably connected in the cavity, and a torsion spring (not shown in the figure) is provided between the transmission rod 24 and the cavity; a horizontally inclined brake rod 25 is welded and fixed on the transmission rod 24, and the adjacent brake rods 25 face opposite directions; several brake blocks 26 are evenly distributed on both sides of the guide rail 5 to abut against the transmission rod 24; when the transmission rod 24 is not deflected, the brake rod 25 does not contact the brake block 26; the lamp holder 2 is provided with a foldable windproof structure.

[0034] When lighting is required, the limiting structure is released from the slide block 6, and the push rod 4 is extended by the control device. The push rod 4 pushes the lamp holder 2 to deflect and lift. When the lamp holder 2 is lifted, the slide block 6 slides along the guide rail 5 through the support rod 7 until the lamp holder 2 deflects to the required lighting angle. The push rod 4 is then stopped extending by the control device. At this time, the slide block 6 is fixed on the guide rail 5 by the limiting structure, and the support rod 7 provides auxiliary support for the lamp holder 2, enhancing the stability of the lamp holder 2 structure. When the lamp holder 2 encounters strong winds during use, the windproof structure is deployed to protect the chandelier 3 and prevent the chandelier 3 from falling due to strong winds during the closing process of the lamp holder 2.

[0035] Furthermore, when the lamp holder 2 is closed or unfolded, the slide 6 slides relative to the guide rail 5. The transmission rod 24 on the slide 6 abuts against the brake block 26, causing the transmission rod 24 to deflect. The transmission rod 24 then drives the brake rod 25 to deflect synchronously. The brake rod 25, which is opposite to the direction of movement of the slide 6, deflects to a position away from the guide rail 5. This brake rod 25 never contacts the brake block 26, while the brake rod 25 on the other side deflects to a position closer to the guide rail 5. When the lamp holder 2 is normally closed or unfolded, the slide 6 slides at a low speed relative to the guide rail 5. At this time, the brake lever 25 is reset by the torsion spring before it comes into contact with the adjacent brake block 26, allowing the slide block 6 to slide normally. When the lamp holder 2 closes or opens too quickly, the slide block 6 slides rapidly relative to the guide rail 5. At this time, the brake lever 25 has not yet been reset by the torsion spring and is in contact with the adjacent brake block 26. Instead, the corresponding transmission rod 24 abuts against the inner wall of the cavity, causing the brake lever 25 to abut against the brake block 26, thus restricting the continued sliding of the slide block 6 and preventing the lamp holder 2 from closing or opening too quickly, which could damage the lamp holder 2.

[0036] In this embodiment, the windproof structure includes side wind deflectors 8 respectively disposed on both sides of the lamp holder 2. A rotating shaft 9 is fixed to the top of each side wind deflector 8, and the rotating shaft 9 is parallel to the side wind deflector 8. The rotating shaft 9 is rotatably connected to the corresponding side wall of the lamp holder 2. A driving device for driving the rotating shaft 9 is disposed on the side wall of the lamp holder 2 (in this embodiment, a motor drive is used, which is a conventional technical means and is therefore not shown in the figure). A slide rail 10 is hinged to the bottom of each side wind deflector 8, and the slide rail 10 is parallel to the side wind deflector 8. Several connecting rods 11 are horizontally and vertically arranged between the slide rails 10. 1. Connecting seats 12 are slidably provided at both ends along their axial direction. The connecting seats 12 are slidably connected to the corresponding slide rails 10. The connecting seats 12 are provided with a power device to drive them to slide on the slide rails 10 (in this embodiment, a motor drive is used, which is a conventional technical means and is not shown in the figure); Windproof plates 13 are hinged on both sides of the connecting rod 11, and adjacent windproof plates 13 are hinged together; The length and width of the lamp holder 2 are both greater than the support base 1. The chandelier 3 is set on the end of the lamp holder 2 that extends out of the support base 1, so that the windproof structure does not contact the support base 1 after it is unfolded, so that the lamp holder 2 can be closed normally.

[0037] When the lamp holder 2 encounters strong winds while in its extended state, the drive device drives the rotating shaft 9 to deflect in the forward direction until the rotating shaft 9 drives the side wind deflector 8 to deflect vertically downwards. When the wind direction is directly opposite the side wind deflector 8, the side wind deflector 8 deflects downwards to prevent strong winds from directly hitting the side wind deflector 8, thus preventing the lamp holder 2 from being subjected to lateral forces and affecting the rapid closing of the lamp holder 2. As the side wind deflector 8 unfolds, it drives the slide rail 10 to move diagonally downwards, and the slide rail 10 drives the connecting seat 12 to slide relative to the connecting rod 11, causing the rod 11 to move downwards synchronously. After the side wind deflector 8 unfolds, the power device drives the connecting seat 12 to drive the connecting rod 11 to slide along the slide rail 10, causing the windproof plate 13 between the connecting rods 11 to unfold. The side wind deflector 8 and the windproof plate 13 effectively shield the chandelier 3, preventing the chandelier 3 from falling due to strong winds. In addition, after the windproof structure is unfolded, it can also be used as a maintenance passage for the lamp holder 2, making it easier for maintenance personnel to directly access the chandelier 3 and perform maintenance on the chandelier 3 in a safer manner.

[0038] After the strong wind subsides, the drive device drives the rotating shaft 9 to deflect in the opposite direction until the rotating shaft 9 drives the side wind deflector 8 to deflect to fit against the lower end of the lamp holder 2. As the side wind deflector 8 closes, it drives the slide rail 10 to move obliquely upward. The slide rail 10 then drives the connecting seat 12 to slide relative to the connecting rod 11, causing the connecting plate 11 to reset synchronously. After the side wind deflector 8 unfolds, the power device drives the connecting seat 12 to drive the connecting rod 11 to slide and reset along the slide rail 10, causing the windproof plate 13 between the connecting rods 11 to fold and expose the chandelier 3.

[0039] In this embodiment, two symmetrically arranged mounting seats 14 are integrally formed on the end face of the windproof plate 13 away from the chandelier 3. The mounting seats 14 are rotatably connected by a rotating shaft 15 parallel to the windproof plate 13. Several blades 16 are welded on the rotating shaft 15. Both ends of the rotating shaft 15 have coaxial circular cavities. The circumference of the circular cavities is provided with wavy annular grooves 17. Hydraulic dampers 18 facing the rotating shaft 15 are fixed on the opposite end faces of the mounting seats 14. The output end of the hydraulic damper 18 passes through the mounting seat 14 and extends into the circular cavity. Several support rods 19 extending into the annular grooves 17 are fixed on the circumference of the output end of the hydraulic damper 18.

[0040] During the closing process of the lamp holder 2, if the wind direction is directly facing the windproof plate 13, the wind blows towards the windproof plate 13. At this time, the wind blows the blades 16, which drive the rotating shaft 15 to rotate. During the rotation of the rotating shaft 15, the support rod 19 output by the hydraulic damper 18 rotates continuously along the annular groove 17. Since the annular groove 17 is wavy, the support rod 19 continuously reciprocates along its axis during rotation, thereby driving the hydraulic damper 18 to dissipate hydraulic energy and prevent strong winds from blowing onto the lower end face of the lamp holder 2, giving the lamp holder 2 the kinetic energy to lift, and affecting the closing of the lamp holder 2.

[0041] In this embodiment, the limiting structure includes a through hole opened on the slide 6, all of which face the guide rail 5. A telescopic rod 20 is provided in the through hole, and the guide rail 5 is provided with a plurality of limiting holes that cooperate with the telescopic rod 20.

[0042] When the lamp holder 2 needs to be opened or closed, the control telescopic rod 20 is shortened and disengaged from the limiting hole, thereby releasing the limiting structure from limiting the slide 6, allowing the slide 6 to slide along the guide rail 5; when the lamp holder 2 is opened or closed, the control telescopic rod 20 is extended and inserted into the limiting hole, fixing the slide 6 to the guide rail 5 through the limiting structure, and using the support rod 7 to provide auxiliary fixation for the lamp holder 2.

[0043] In this embodiment, an auxiliary support structure is provided between adjacent connecting rods 11. The auxiliary support structure includes two support rods 21 that are hinged to each other in the middle. Both ends of the support rods 21 are hinged to supports 23, and the supports 23 are slidably connected to the adjacent connecting rods 11 along the axial direction. By providing support rods 21, the windproof plate 13 is supported after it is unfolded.

[0044] In this embodiment, the side wind deflector 8 is a telescopic structure; by controlling the length of the side wind deflector 8, the unfolding space of the windproof structure is controlled, so as to facilitate the use of maintenance personnel.

[0045] In this embodiment, a front windshield 22 is integrally formed on one end of the lamp holder 2 that extends out of the support base 1. The front windshield 22 forms a more enclosed space for the windproof structure after it is unfolded, further avoiding the impact of strong winds on the chandelier 3.

[0046] A method of using an openable lamp holder 2 includes the following steps:

[0047] 1) Lamp holder 2 opening: When lighting is required, control the telescopic rod 20 to shorten, and the telescopic rod 20 disengages from the limiting hole, thereby releasing the limiting structure from limiting the slide 6. Then, control the push rod 4 to extend through the control device. The push rod 4 pushes the lamp holder 2 to deflect and lift. When the lamp holder 2 is lifted, the support rod 7 drives the slide 6 to slide along the guide rail 5 until the lamp holder 2 deflects to the required lighting angle. Control the push rod 4 to stop extending through the control device. At this time, control the telescopic rod 20 to extend and insert it into the limiting hole. The limiting structure fixes the slide 6 on the guide rail 5, and the support rod 7 provides auxiliary support for the lamp holder 2.

[0048] 2) Windproof structure deployment: In strong wind conditions, the drive device drives the rotating shaft 9 to deflect until the rotating shaft 9 drives the side wind deflector 8 to deflect vertically downward; when the wind direction is directly opposite the side wind deflector 8, the side wind deflector 8 deflects downward to avoid strong winds directly hitting the side wind deflector 8, preventing the lamp holder 2 from being subjected to lateral force and affecting the rapid closing of the lamp holder 2; at the same time as the side wind deflector 8 is deployed, it drives the slide rail 10 to move obliquely downward, and the slide rail 10 drives the connecting seat 12 to slide relative to the connecting rod 11, causing the connecting rod 11 to move downward relative to the lamp holder 2; after the side wind deflector 8 is deployed, the power device drives the connecting seat 12 to drive the connecting rod 11 to slide along the slide rail 10, so that the windproof plate 13 between the connecting rods 11 is deployed, and the side wind deflector 8, the front wind deflector and the windproof plate 13 effectively shield the chandelier 3 to prevent the chandelier 3 from falling due to strong winds;

[0049] 3) Closing of the lamp holder 2: The limiting structure is released from the sliding block 6, and the push rod 4 is shortened by the control device. The push rod 4 drives the lamp holder 2 to deflect and descend. When the lamp holder 2 descends, the sliding block 6 slides along the guide rail 5 through the support rod 7 until the lamp holder 2 closes. At this time, the limiting structure fixes the sliding block 6 on the guide rail 5, which plays a role in fixing the lamp holder 2. During the closing process, when the wind direction is facing the windproof plate 13, the wind blows the blade 16 to drive the rotating shaft 15 to rotate. During the rotation of the rotating shaft 15, the support rod 19 at the output end of the hydraulic damper 18 rotates continuously along the annular groove 17. Since the annular groove 17 is wavy, the support rod 19 continuously reciprocates along its axis during the rotation, thereby driving the hydraulic damper 18 to dissipate hydraulic energy and prevent strong winds from blowing onto the lower end of the lamp holder 2, giving the lamp holder 2 the kinetic energy to lift it and affecting the closing of the lamp holder 2. In addition, when the lamp holder 2 is closed or unfolded, the sliding block 6 slides relative to the guide rail 5. The transmission rod 24 on the slide block 6 abuts against the brake block 26, causing the transmission rod 24 to deflect. The transmission rod 24 then drives the brake rod 25 to deflect synchronously. The brake rod 25, which is away from the direction of movement of the slide block 6, deflects to a position away from the guide rail 5. This brake rod 25 never contacts the brake block 26, while the brake rod 25 on the other side deflects to a position close to the guide rail 5. When the lamp holder 2 closes or opens normally, the slide block 6 slides at a low speed relative to the guide rail 5. At this time, the brake rod 25 is reset by the torsion spring before it contacts the adjacent brake block 26, allowing the slide block 6 to slide normally. When the lamp holder 2 closes or opens too quickly, the slide block 6 slides quickly relative to the guide rail 5. At this time, the brake rod 25 has not yet been reset by the torsion spring before it contacts the adjacent brake block 26, and the corresponding transmission rod 24 abuts against the inner wall of the cavity, causing the brake rod 25 to abut against the brake block 26, limiting the continued sliding of the slide block 6, thereby preventing the lamp holder 2 from closing or opening too quickly and causing damage to the lamp holder 2.

[0050] 4) Windproof structure closure: After the strong wind ends, the drive device drives the rotating shaft 9 to deflect in the opposite direction until the rotating shaft 9 drives the side wind deflector 8 to deflect to fit against the lower end face of the lamp holder 2; at the same time as the side wind deflector 8 closes, it drives the slide rail 10 to move obliquely upward, and the slide rail 10 drives the connecting seat 12 to slide relative to the connecting rod 11 to make the connecting rod 11 return to its original position synchronously; after the side wind deflector 8 closes, the power device drives the connecting seat 12 to drive the connecting rod 11 to slide and return to its original position along the slide rail 10, so that the windproof plate 13 between the connecting rods 11 folds, exposing the chandelier 3.

[0051] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.

6. The retractable light fixture structure for a sports stadium according to claim 5, characterized in that: A front windshield is provided on one end of the lamp holder that extends out of the support base.

7. The method of using the retractable lighting structure for a sports stadium according to claim 6, characterized in that, Includes the following steps: 1) Lamp holder opening: When lighting is required, the telescopic rod is shortened and disengaged from the limiting hole, thereby releasing the limiting structure from the slide block. The push rod is then extended by the control device, pushing the lamp holder to deflect and lift. When the lamp holder is lifted, the slide block slides along the guide rail through the support rod until the lamp holder deflects to the required lighting angle. The push rod is then stopped by the control device. At this time, the telescopic rod is extended and inserted into the limiting hole. The limiting structure fixes the slide block to the guide rail, and the support rod provides auxiliary support for the lamp holder. 2) Windproof Structure Deployment: In strong wind conditions, the drive device drives the rotating shaft to deflect until the shaft drives the side wind deflector to a vertical downward position. When the wind direction is directly opposite the side wind deflector, the side wind deflector tilts downward to prevent strong winds from directly hitting the side wind deflector and to prevent the lamp holder from being subjected to lateral forces, which would affect the lamp holder's rapid closure. As the side wind deflector deploys, it drives the slide rail to move diagonally downward. The slide rail then drives the connecting seat to slide relative to the connecting rod, causing the connecting rod to move downward relative to the lamp holder. After the side wind deflector is deployed, the power device drives the connecting seat to move the connecting rod along the slide rail, causing the windproof plate between the connecting rods to deploy. The side wind deflector, front wind deflector, and windproof plate effectively shield the chandelier, preventing the chandelier from falling due to strong winds. 3) Lamp Stand Closure: The limiting structure restricts the slide block, and the push rod is shortened by the control equipment. The push rod drives the lamp stand to deflect and descend. When the lamp stand descends, the slide block slides along the guide rail through the support rod until the lamp stand closes. At this time, the limiting structure fixes the slide block on the guide rail, which plays a role in fixing the lamp stand. During the closure process, when the wind direction is directly facing the windproof plate, the wind blows the blades and drives the rotating shaft to rotate. During the rotation of the rotating shaft, the support rod at the output end of the hydraulic damper rotates continuously along the annular groove. Since the annular groove is wavy, the support rod continuously reciprocates along its axis during rotation, which in turn drives the hydraulic damper to dissipate hydraulic energy and prevent strong winds from blowing onto the lower end of the lamp stand, giving the lamp stand the kinetic energy to lift it and affecting the closure of the lamp stand. In addition, when the lamp stand is closed or unfolded, the slide block relative to the guide rail... When the slide rail slides, the transmission rod on the slide block abuts against the brake block, causing the transmission rod to deflect. The transmission rod then drives the brake rod to deflect synchronously. The brake rod on the opposite side of the slide block's direction of movement deflects to a position away from the guide rail, and this brake rod never contacts the brake block. Meanwhile, the brake rod on the other side deflects to a position closer to the guide rail. When the lamp holder closes or opens normally, the slide block slides at a low speed relative to the guide rail. At this time, the brake rod is reset by the torsion spring before contacting the adjacent brake block, allowing the slide block to slide normally. When the lamp holder closes or opens too quickly, the slide block slides rapidly relative to the guide rail. At this time, the brake rod has not yet been reset by the torsion spring before contacting the adjacent brake block. Instead, the corresponding transmission rod abuts against the inner wall of the cavity, causing the brake rod to abut against the brake block, limiting the continued sliding of the slide block and thus preventing the lamp holder from closing or opening too quickly, which could damage the lamp holder. 4) Windproof structure closure: After the strong wind ends, the drive device drives the rotating shaft to deflect in the opposite direction until the rotating shaft drives the side wind deflector to fit against the lower end of the lamp holder; at the same time as the side wind deflector closes, it drives the slide rail to move obliquely upward, and the slide rail drives the connecting seat to slide relative to the connecting rod, causing the connecting rod to return to its original position synchronously; after the side wind deflector closes, the power device drives the connecting seat to drive the connecting rod to slide along the slide rail to return to its original position, so that the windproof plate between the connecting rods folds and exposes the chandelier.
