Description

Technical Field

[0001] This invention relates to the field of high mast lighting technology, and more particularly to a sub-panel for a high mast lighting system. Background Technology

[0002] The dual-lift system high mast light uses a main lifting system and a secondary lifting system operating in parallel. The main lifting system controls the raising and lowering of the main panel along the mast, while the secondary lifting system controls the raising and lowering of the secondary panel. The main panel is located at the top of the mast and is used to install lighting and control equipment. The secondary panel is located in the middle of the mast and is used to install monitoring equipment.

[0003] In existing technology, both the main and auxiliary disks adopt a fixed frame structure, and the dimensions of the two disks remain unchanged. Furthermore, the dimensions of the main and auxiliary disks are similar. This fixed frame structure has the following drawbacks.

[0004] (1) When the main plate needs to be lowered to the bottom of the pole for maintenance, the secondary plate must be lowered first. Otherwise, the main plate will not be able to pass through the secondary plate because the diameters of the two plates are close. Therefore, the secondary plate must be lowered to the bottom of the pole first, and then the main plate is lowered to the bottom of the pole, resulting in low maintenance efficiency and increased maintenance costs.

[0005] (2) When the main panel is lowered to the bottom of the pole for maintenance, the secondary panel must be lowered first, which will cause the monitoring equipment on the secondary panel to malfunction and the monitoring must be interrupted. That is, when the main panel is being repaired or the main panel is lowered in windy weather, the monitoring equipment installed on the secondary panel will not work properly, thus making it impossible to maintain the monitoring status in bad weather or when the equipment on the main panel is being maintained.

[0006] (3) The sub-disc adopts a fixed frame structure with a fixed diameter, while the rod is a tapered rod with a diameter that gradually decreases from bottom to top. Therefore, the inner diameter of the sub-disc needs to be matched with the maximum diameter at the bottom of the rod. As a result, when the sub-disc is raised to a high position, there is a large space between the inner diameter of the sub-disc and the rod, which affects the aesthetics.

[0007] (3) The auxiliary panel adopts a rectangular bending process. The equipment wiring on the auxiliary panel is laid on the surface of the panel profile and exposed to the outside. It is susceptible to corrosion from ultraviolet rays and rainwater, which affects the cable life.

[0008] (4) The installation position of the monitoring equipment on the sub-panel cannot be adjusted. Summary of the Invention

[0009] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a secondary panel for a high mast light that can achieve the goal of lowering the secondary panel without lowering the main panel to the bottom of the mast.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] This invention provides a sub-disc for a high-mast light, which is vertically and flexibly mounted on the pole. It includes multiple fixed buffer structures spaced circumferentially along the pole. The upper end of each fixed buffer structure is connected to the pole and can rotate relative to it, allowing the lower end of the fixed buffer structure to swing in a direction away from or towards the pole. Each pair of adjacent fixed buffer structures is connected at their lower ends by a pair of telescopic structures, thus forming a disc. One end of each telescopic structure is a fixed end fixedly connected to the lower end of the fixed buffer structure, and the other end is a movable end that can extend or retract. The movable ends of each pair of telescopic structures are hinged together. The diameter of the disc increases or decreases as the movable ends of the telescopic structures extend or retract.

[0012] Preferably, the telescopic structure includes a fixed side ring, a folding arm, a connecting arm, and a telescopic drive component. The first end of the fixed side ring is the fixed end of the telescopic structure. The second end of the fixed side ring is connected to the first end of the folding arm and forms an angle. The second end of the folding arm is hinged to the first end of the connecting arm. The second end of the connecting arm is the movable end of the telescopic structure. The folding arm is driven by the telescopic drive component to open or fold along the circumference of the disc, causing the second end of the connecting arm to extend or retract.

[0013] Preferably, the folding arm includes a first arm and a second arm. The first end of the first arm is connected to the second end of the fixed side ring at an angle. The second end of the first arm is hinged to the first end of the second arm and forms a V-shape. The second end of the second arm is hinged to the first end of the connecting arm.

[0014] Preferably, the telescopic drive has a support end rotatably mounted on the first arm and a telescopic end that is hinged to the first end of the connecting arm.

[0015] Preferably, a connector is provided on the first end of the connecting arm, and the telescopic end of the telescopic drive is hinged to the connector. The connection position of the connector on the first end of the connecting arm is adjustable.

[0016] Preferably, the second end of the first arm and the first end of the second arm, as well as the second end of the second arm and the first end of the connecting arm, are hinged by damping hinges.

[0017] Preferably, the angle between the fixed side ring and the folding arm is adjustable.

[0018] Preferably, the connecting arm is used to install monitoring equipment, and the connecting arm is made of aluminum profile. The installation position of the monitoring equipment on the aluminum profile is adjustable.

[0019] Preferably, both the fixed side ring and the connecting arm are hollow structures with internal through-holes, and the internal space of the fixed side ring and the connecting arm is used to arrange cables.

[0020] Preferably, the fixed buffer structure includes a slider that is slidably connected to the rod, a pulley frame that is fixedly connected to the slider, a fixed arm that is hinged to the pulley frame at its upper end, a connecting frame that is hinged to the lower end of the fixed arm, a guide rod that is suspended on the connecting frame at its upper end, a fixed plate located at the lower end of the guide rod, and a spring sleeved on the guide rod. The spring elastically presses against the connecting frame and the fixed plate. A main pulley is installed inside the pulley frame. A wire rope driven by a winch passes through the connecting frame and the fixed arm in sequence, goes around the main pulley, passes through the fixed arm and the connecting frame again, and is connected to the fixed plate. The fixed end of the telescopic structure is fixedly connected to the connecting frame.

[0021] Compared with the prior art, the present invention has significant progress:

[0022] The secondary panel of the high-mast light of the present invention is formed by connecting the lower end of an adjacent fixed buffer structure through an extendable or retractable telescopic structure. The diameter of the panel is adjustable by the extension or retraction of the telescopic structure and the swinging of the lower end of the fixed buffer structure in a direction away from or towards the pole. This allows the diameter of the secondary panel to be adjusted according to usage needs. When the main panel needs to be lowered to the bottom of the pole for maintenance, the secondary panel does not need to be lowered. The main panel can be directly lowered to the bottom of the pole by adjusting the diameter of the secondary panel to the minimum. This can significantly improve maintenance efficiency and reduce maintenance costs. Furthermore, the secondary panel is not affected when the main panel is lowered, so that the monitoring equipment on the secondary panel can operate normally and maintain monitoring status.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0069] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0070] like Figures 1 to 9As shown, this embodiment of the invention provides a sub-panel 100 for a high mast light, which is applied to a high mast light with a dual-lifting system. The dual-lifting system high mast light also includes a main pan 200 and a pole 300 serving as the light pole. The pole 300 is vertically arranged and is a tapered pole with a diameter gradually decreasing from bottom to top. The main pan 200 is movably mounted on the pole 300, with its working position at the top of the pole 300. The main pan 200 is driven by a matching main lifting system and can move up and down along the pole 300. The main pan 200 is mainly used for installing lighting and control equipment. The sub-panel 100 is movably mounted on the pole 300, with its working position at the middle of the pole 300, thus the sub-panel 100 is located below the main pan 200. The sub-panel 100 is driven by a matching secondary lifting system and can move up and down along the pole 300. The sub-panel 100 is mainly used for installing monitoring equipment. To address the issue in existing technologies where the auxiliary panel 100 needs to be lowered before maintenance is performed when the main panel 200 is lowered to the bottom of the pole 300, the auxiliary panel 100 of the high-mast light in this embodiment of the invention is designed as a telescopic frame structure with an adjustable panel diameter, so that the auxiliary panel 100 does not need to be lowered when the main panel 200 is lowered to the bottom of the pole 300.

[0071] The sub-panel 100 of the high-mast light in this embodiment includes multiple fixed buffer structures 1, which are evenly spaced along the circumference of the pole 300. Each fixed buffer structure 1 has the same structural composition. Preferably, two fixed buffer structures 1 may be provided, symmetrically arranged on the outer peripheral side of the pole 300.

[0072] See Figure 1 and Figure 5 The upper end of the fixed buffer structure 1 is connected to the rod 300 and can rotate relative to the rod 300, causing the lower end of the fixed buffer structure 1 to swing in a direction away from or towards the rod 300. Simultaneously, the upper end of the fixed buffer structure 1 slides against the rod 300, allowing the sub-disc 100 to rise and fall along the rod 300. Each pair of adjacent fixed buffer structures 1 are connected by a pair of telescopic structures 2, forming a disc that surrounds the outer periphery of the rod 300. Each pair of telescopic structures 2 comprises two connected telescopic structures 2. One end of each telescopic structure 2 is a fixed end fixedly connected to the lower end of the fixed buffer structure 1, and the other end of each telescopic structure 2 is a movable end that can extend or retract relative to its fixed end. The movable ends of each pair of telescopic structures 2 are hinged together. The diameter of the disc increases or decreases as the movable end of the telescopic structure 2 extends or retracts: When the movable end of the telescopic structure 2 extends or retracts, each pair of telescopic structures 2 simultaneously pushes and pulls the lower ends of the two fixed buffer structures 1 connected to it, causing the lower ends of the fixed buffer structures 1 to swing in a direction away from or closer to the rod 300. The radial distance between the lower end of the fixed buffer structure 1 and the rod 300 increases or decreases accordingly. Combined with the extension or retraction of the telescopic structure 2 itself, the diameter of the disc increases or decreases accordingly.

[0073] Therefore, the auxiliary panel 100 of the high mast light in this embodiment can have its diameter adjusted according to usage needs. The maximum and minimum adjustable diameter of the auxiliary panel 100 are determined based on the diameter of the mast 300 and the inner diameter of the main panel 200. When the auxiliary panel 100 is equipped with the monitoring device 400 and is located in the working position in the middle of the mast 300, the diameter of the auxiliary panel 100 is adjusted to its minimum value. The minimum adjustable diameter of the auxiliary panel 100 ensures that the diameter of the outermost circle of the overall outer perimeter of the auxiliary panel 100 and the monitoring device 400 is smaller than the inner diameter of the main panel 200, while reserving a safe distance (e.g., ...). Figure 2 As shown in the diagram, when the main panel 200 needs to be lowered to the bottom of the pole 300 for maintenance, there is no need to lower the auxiliary panel 100. The main panel 200 can be directly lowered to the bottom of the pole 300 via the auxiliary panel 100. The reserved safety distance can prevent the main panel 200 from colliding with the auxiliary panel 100 due to the shaking of the light panel (main panel 200 or auxiliary panel 100) when passing the auxiliary panel 100. This can significantly improve maintenance efficiency and reduce maintenance costs. Furthermore, the auxiliary panel 100 is not affected when the main panel 200 is lowered, and the monitoring equipment 400 on the auxiliary panel 100 can operate normally and maintain monitoring status. At the same time, the minimum adjustable panel diameter of the auxiliary panel 100 makes the inner diameter of the auxiliary panel 100 as close as possible to the diameter of the middle part of the pole 300, thereby leaving a small gap space between the inner circle of the auxiliary panel 100 and the pole 300, increasing aesthetics. When the auxiliary panel 100 needs to be lowered to the bottom of the pole 300 for maintenance or installation of monitoring equipment 400, due to the large diameter of the bottom of the pole 300, the diameter of the auxiliary panel 100 is adjusted to its maximum value. The maximum adjustable diameter of the auxiliary panel 100 ensures that the inner diameter of the auxiliary panel 100 is larger than the diameter of the bottom of the pole 300 (e.g., ...). Figure 6 As shown), so that the auxiliary plate 100 can be smoothly lowered to the bottom of the pole 300. After the auxiliary plate 100 has been maintained or the monitoring equipment 400 has been installed at the bottom of the pole 300, the auxiliary plate 100 is raised to the working position in the middle of the pole 300 and then the diameter of the auxiliary plate 100 is adjusted to the minimum value.

[0074] See Figure 3 , Figure 4 , Figure 7 and Figure 8 In this embodiment, preferably, the telescopic structure 2 includes a fixed side ring 21, a folding arm 22, a connecting arm 23, and a telescopic drive member 24. The fixed side ring 21, the folding arm 22, and the connecting arm 23 are connected end-to-end along the circumference of the sub-disk 100. The folding arm 22 can open or fold along the circumference of the disk body, and the telescopic drive member 24 acts on the folding arm 22 and drives the folding arm 22 to open or fold along the circumference of the disk body. The extension or contraction of the telescopic structure 2 is achieved by the folding arm 22 opening or folding along the circumference of the disk body.

[0075] Specifically, the first end of the fixed side ring 21 is the fixed end of the telescopic structure 2 and is fixedly connected to the lower end of the fixed buffer structure 1. Preferably, a side ring flange 21a is welded to the first end of the fixed side ring 21, and the side ring flange 21a is fastened to the lower end of the fixed buffer structure 1 by bolts. The second end of the fixed side ring 21 is connected to the first end of the folding arm 22 at an angle, and the second end of the folding arm 22 is hinged to the first end of the connecting arm 23. The second end of the connecting arm 23 is the movable end of the telescopic structure 2, which can extend or retract relative to the fixed end of the telescopic structure 2. The second ends of the connecting arms 23 of each pair of telescopic structures 2 are hinged to each other by a connecting hinge 23a. When the folding arm 22 is driven by the telescopic drive member 24 to open or fold along the circumference of the disc, it drives the second end of the connecting arm 23 to extend or retract, thus realizing the extension or retraction of the telescopic structure 2.

[0076] The folding arm 22 preferably includes a first arm 22a and a second arm 22b. The first end of the first arm 22a is connected to the second end of the fixed side ring 21 at an angle. The second end of the first arm 22a is hinged to the first end of the second arm 22b in a V-shape. The second end of the second arm 22b is hinged to the first end of the connecting arm 23. To ensure the stability of the telescopic structure 2, preferably, the second end of the first arm 22a and the first end of the second arm 22b are hinged together by a damping hinge 25a, and the second end of the second arm 22b and the first end of the connecting arm 23 are hinged together by a damping hinge 25b. When the telescopic structure 2 is extended or retracted, the damping hinges 25a and 25b can provide a certain frictional force to maintain a rigid and wobbly connection between the first arm 22a and the second arm 22b, and between the second arm 22b and the connecting arm 23, thereby ensuring the stability of the telescopic structure 2 and ensuring that the monitoring equipment 400 mounted on the sub-panel 100 maintains a good working condition.

[0077] The angle between the fixed side ring 21 and the folding arm 22 is preferably adjustable. That is, the angle between the second end of the fixed side ring 21 and the first end of the first support arm 22a is adjustable, thereby adjusting the telescopic range of the telescopic structure 2. This allows for the adjustment of the diameter of the auxiliary disk 100 to its maximum and minimum values ​​according to the different diameters of the rod body 300 and the inner ring diameter of the main disk 200. Preferably, the second end of the fixed side ring 21 is provided with two parallel connecting pins 21b, and the first end of the first support arm 22a is provided with multiple connecting pin holes 22c for connecting with the two connecting pins 21b. The first connecting pin hole 22c is connected to the first connecting pin 21b, and the other connecting pin holes 22c are spaced apart on an arc centered on the first connecting pin hole 22c. The second connecting pin 21b is connected to one of the connecting pin holes 22c on this arc, so that the second end of the fixed side ring 21 and the first end of the first support arm 22a are connected at an angle. By changing the connecting pin hole 22c on the arc connected by the second connecting pin 21b, the angle between the second end of the fixed side ring 21 and the first end of the first support arm 22a can be adjusted.

[0078] The telescopic drive member 24 has a support end 24a and a telescopic end 24b that can extend or retract relative to the support end 24a. The support end 24a of the telescopic drive member 24 is rotatably mounted on the first support arm 22a, and the telescopic end 24b of the telescopic drive member 24 is hinged to the first end of the connecting arm 23. The extension or retraction of the telescopic end 24b of the telescopic drive member 24 drives the first end of the connecting arm 23 to move, which in turn drives the second end of the second support arm 22b to move, causing the second end of the second support arm 22b to swing towards or away from the first support arm 22a, thereby opening or closing the folding arm 22 circumferentially around the disc. With the movement of the first end of the connecting arm 23 and the second end of the second support arm 22b, the support end 24a of the telescopic drive member 24 will rotate relative to the first support arm 22a. Preferably, the first arm 22a has an internally hollow structure to accommodate the support end 24a of the telescopic drive member 24 and provide space for the rotation of the support end 24a relative to the first arm 22a. A mounting base 26 is fixedly mounted on the first arm 22a, and the support end 24a of the telescopic drive member 24 is rotatably connected to the mounting base 26 within the internal hollow space of the first arm 22a via a first connecting shaft 26a.

[0079] Preferably, a connector 27 is provided on the first end of the connecting arm 23. The telescopic end 24b of the telescopic drive member 24 is hinged to the connector 27 via a second connecting shaft 27a. The connection position of the connector 27 on the first end of the connecting arm 23 is adjustable, thereby adjusting the telescopic range of the telescopic structure 2. This allows for the adjustment of the diameter of the sub-disc 100 to the maximum and minimum values ​​depending on the diameter of the rod 300 and the inner diameter of the main disc 200. More preferably, both the connector 27 and the first end of the connecting arm 23 have multiple connecting holes along the extension direction of the connecting arm 23. By fastening one connecting hole on the connector 27 to one connecting hole on the first end of the connecting arm 23 with a bolt, the connector 27 can be fixedly connected to the first end of the connecting arm 23. By changing the position of the connecting hole connected to the bolt, the connection position of the connector 27 on the first end of the connecting arm 23 can be adjusted.

[0080] In this embodiment, the telescopic drive components 24 in all telescopic structures 2 extend and retract synchronously at each node. By controlling the extension and retraction length of the telescopic end 24b of the telescopic drive component 24, the extension or contraction range of the telescopic structure 2 can be controlled, thereby controlling the change range of the disc diameter of the sub-disc 100. Preferably, the telescopic drive component 24 is an electric actuator, which is communicatively connected to a controller. The controller can be a conventional PLC controller or a microcontroller. The controller controls the rotation angle of the electric actuator motor, and can adjust and control the extension and retraction length of the electric actuator, thereby regulating the extension or contraction range of the telescopic structure 2. At the same time, the electric actuator has a limit and self-locking function, and can stop and hold at any position during the extension and retraction process, thereby ensuring that the disc of the sub-disc 100 will not deform or contract due to its own weight or wind force, maintaining a certain stability, and giving the disc of the sub-disc 100 a self-locking function.

[0081] To prevent malfunction or failure of the limit switch built into the electric actuator, preferably, a limit switch is installed at the angle between the first arm 22a and the second arm 22b of the folding arm 22 to detect the size of the angle between them. This limit switch is communicatively connected to the controller and transmits the detected angle signal to the controller. The controller determines whether the opening or closing angle of the folding arm 22 is too large or too small based on the received angle signal. If so, it controls the motor of the electric actuator to reduce or increase the rotation angle or stop rotation. This provides a double safety measure, preventing damage caused by friction or collision between the two components of the telescopic structure.

[0082] In this embodiment, the axes of the connecting pin 21b between the second end of the fixed side ring 21 and the first end of the first support arm 22a, the hinge axis (axis of damping hinge 25a) between the second end of the first support arm 22a and the first end of the second support arm 22b, the hinge axis (axis of damping hinge 25b) between the second end of the second support arm 22b and the first end of the connecting arm 23, the axis of the first connecting shaft 26a between the support end 24a of the telescopic drive member 24 and the mounting base 26, and the axis of the second connecting shaft 27a between the telescopic end 24b of the telescopic drive member 24 and the connecting member 27 are parallel to each other and extend approximately horizontally. The hinge axis (axis of connecting hinge 23a) of the second end of the connecting arm 23 of each pair of telescopic structures 2 extends approximately vertically to achieve the best overall extension or retraction effect of the sub-disc 100.

[0083] In this embodiment, preferably, the connecting arm 23 is used to install the monitoring device 400. The connecting arm 23 is made of aluminum profile, and the installation position of the monitoring device 400 on the aluminum profile is adjustable. The installation position of the monitoring device 400 on the aluminum profile can be easily adjusted by the grooves on the four edges of the aluminum profile. In addition, the fixing side ring 21 can also be used to install equipment such as cameras.

[0084] In this embodiment, preferably, the fixed side ring 21 and the connecting arm 23 are both hollow structures with internal through-holes. The internal space of the fixed side ring 21 and the connecting arm 23 is used to arrange the cable. The cable is placed in the drag chain and can be bent and twisted with the deformation of the telescopic structure 2, thereby avoiding the cable from being scratched by the disc structure components due to the expansion and contraction of the sub-disc 100. It can also prevent the cable from being exposed to the outside, thus playing a good protective role for the cable.

[0085] Combination Figure 9In this embodiment, preferably, the fixed buffer structure 1 includes a slider 11 slidably connected to the rod 300, a pulley frame 12 fixedly connected to the slider 11, a fixed arm 13 hinged to the pulley frame 12 at its upper end, a connecting frame 14 hinged to the lower end of the fixed arm 13, a guide rod 15 suspended vertically on the connecting frame 14 at its upper end, a fixed plate 16 located at the lower end of the guide rod 15, and a spring 17 sleeved on the guide rod 15. The spring 17 elastically presses against the connecting frame 14 and the fixed plate 16. A main pulley 18 is installed inside the pulley frame 12. A wire rope (not shown in the figure) driven by a winch passes through the connecting frame 14 and the fixed arm 13 in sequence, goes around the main pulley 18, passes through the fixed arm 13 and the connecting frame 14 again, and is connected to the fixed plate 16. The winch is located inside the pole cavity of pole 300. The wire rope connected to the winch passes through the top of the pole cavity of pole 300 and extends downwards from the outside of pole 300 to the fixed buffer structure 1. From the bottom of the connecting frame 14, it passes through the connecting frame 14 and the fixed arm 13 to reach the main pulley 18. After passing around the main pulley 18, it passes downwards through the fixed arm 13 and the connecting frame 14 to reach the fixed plate 16, where it is fixedly connected. The cable runs in the same direction as the wire rope. The fixed end of the telescopic structure 2 is fixedly connected to the connecting frame 14, that is, the side flange 21a on the first end of the fixed side ring 21 is fastened to the connecting frame 14 by bolts. Thus, when the winch drives the wire rope to move, the wire rope acts on the fixed buffer structure 1, which can drive the auxiliary disc 100 to rise and fall along pole 300. During the process of the wire rope driving the fixed buffer structure 1 to rise and fall, the spring 17 is elastically compressed or extended, playing a buffering role.

[0086] In this embodiment, the pulley frame 12 and the slider 11 are fastened together by bolts. The upper end of the fixed arm 13 is rotatably connected to the pulley frame 12 by bolts, and the lower end of the connecting frame 14 is rotatably connected to the fixed arm 13 by bolts. An auxiliary pulley 19 is preferably installed inside the connecting frame 14. When the wire rope and cable pass through the connecting frame 14, they pass through and contact the auxiliary pulley 19, which provides auxiliary support for the wire rope and cable. A pressure plate 16a is preferably provided on the fixing plate 16 for fixing the wire rope and cable.

[0087] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
