DETAILED DESCRIPTION

[0035] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated. The special word "exemplary" here means "used as an example, embodiment or illustrative". Any embodiment described here as "exemplary" is not necessarily interpreted as being superior or better than other embodiments. In addition, in order to better illustrate the present application, those skilled in the art will understand that numerous specific details are given in each embodiment below. The present application can also be implemented without certain specific details. In some embodiments, methods, means and elements well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0036] As shown in Figures 1 to 3, an embodiment of the present application provides a traffic light, including a lamp pole 100, a cantilever 102 and a lamp body 104. The lamp pole 100 is arranged vertically, the cantilever 102 is arranged horizontally and one end is fixedly connected to the upper end of the lamp pole 100, and the lamp body 104 is connected to the cantilever 102. It also includes a guide rail 106, a seat 108, and a traction assembly. The guide rail 106 extends upward from the lower end of the lamp pole 100, then turns to the cantilever 102 at the upper end of the lamp pole 100, and then extends along the cantilever 102. The guide rail 106 is fixedly connected to the lamp pole 100 and the cantilever 102 respectively; the lamp body 104 is fixedly connected to the seat 108, and the seat 108 is slidably connected to the guide rail 106. One end of the traction assembly is connected to the seat 108, and the other end of the traction assembly extends along the cantilever 102 and the lamp pole 100 to the lower end of the lamp pole 100. The traction assembly is suitable for pulling the seat 108 to slide along the guide rail 106.

[0037] The traffic light provided in this embodiment can drive the seat 108 to slide along the guide rail 106 to the lower end of the lamp pole 100 by pulling the traction assembly at the lower end of the lamp pole 100 when the lamp body 104 needs to be maintained. After the seat 108 slides to the lower end of the lamp pole 100, the lamp body 104 is maintained. After the maintenance of the lamp body 104 is completed, the seat 108 is pulled in the opposite direction by the traction assembly to slide the seat 108 along the guide rail 106 to the cantilever 102. The entire maintenance process does not require height work (i.e., there is no need to climb up the cantilever 102 with a larger height), is easy to operate, and helps to improve maintenance work efficiency and reduce the risk of maintenance operations.

[0038] As shown in Figures 4 and 5, in some exemplary implementations of this embodiment, the base body 108 includes a slider 110 and a mounting plate 112. The cross-sectional shape of the guide rail 106 is an inverted T-shape. The upper surface of the slider 110 is provided with a slide groove 114 that matches the guide rail 106. The guide rail 106 is inserted into the slide groove 114 and is slidably connected to the slide groove 114. The mounting plate 112 is vertically arranged, and the lamp body 104 is fixedly connected to one side of the mounting plate 112.

[0039] Through the above exemplary implementation of this embodiment, the guide rail 106 can guide the base 108 while also supporting the base 108 , so that the base 108 is suspended on the guide rail 106 .

[0040] In some exemplary implementations of this embodiment, the base 108 also includes a solar cell 116, which is fixedly connected to the mounting plate 112. The solar cell 116 and the lamp body 104 are respectively located on both sides of the mounting plate 112. The solar cell 116 is connected to the circuit board in the lamp body 104 and is used to power the LED lamp beads in the lamp body 104. The mounting plate 112 is located directly below the central axis of the cantilever 102, and the weight of the solar cell 116 is equal to the weight of the lamp body 104.

[0041] Through the above exemplary implementation of this embodiment, the weight of the solar cell 116 is equal to that of the lamp body 104 , which helps to improve the stability of the base body 108 suspended below the guide rail 106 (the forces on both sides of the mounting plate 112 are more balanced).

[0042] As shown in Figures 6 to 11, in some exemplary implementations of the present embodiment, the traction assembly includes a delivery traction rope 118, a first guide wheel 120, and a second guide wheel 122. The first guide wheel 120 is located at one end of the cantilever 102 away from the lamp pole 100 and is rotatably connected to the cantilever 102. The second guide wheel 122 is located at the upper end of the lamp pole 100 and is rotatably connected to the lamp pole 100. The second guide wheel 122 is aligned with the axial direction of the cantilever 102. One end of the delivery traction rope 118 is fixedly connected to the base body 108. The other end of the delivery traction rope 118 is sequentially overlapped on the first guide wheel 120 and the second guide wheel 122, and then extends downward along the lamp pole 100 to the lower end of the lamp pole 100.

[0043] Through the above exemplary implementation of this embodiment, when the delivery traction rope 118 is pulled downward at the lower end of the lamp pole 100, the delivery traction rope 118 generates an upward pulling force on the seat body 108, causing the seat body 108 to slide upward along the guide rail 106 to the upper end of the lamp pole 100, and then continue to pull the delivery traction rope 118 downward. Under the guidance of the guide rail 106, the seat body 108 slides along the guide rail 106 to the cantilever 102, and slides toward the end of the cantilever 102 away from the lamp pole 100, completing the delivery of the lamp body 104.

[0044] In some exemplary implementations of this embodiment, the cantilever 102 and the lamp pole 100 are hollow structures, and one end of the traction rope 118 extends along the inside of the cantilever 102 and the lamp pole 100 to the lower end of the lamp pole 100 .

[0045] Through the above exemplary implementation of this embodiment, the traction rope 118 is routed (or wired) along the inside of the cantilever 102 and the lamp pole 100, which helps to improve the neatness of the wiring harness and can prevent the traction rope 118 from being exposed to sunlight.

[0046] In some exemplary implementations of this embodiment, the traction assembly also includes a recovery traction rope 124 and a third guide wheel 126. The third guide wheel 126 is located at the lower end of the lamp pole 100 and is rotatably connected to the lamp pole 100. The lamp pole 100 is a hollow structure. One end of the recovery traction rope 124 is fixedly connected to the seat body 108. The other end of the recovery traction rope 124 is overlapped on the third guide wheel 126 and then extends into the interior of the lamp pole 100 (a through hole is provided on the side wall of the lamp pole 100, and the end of the recovery traction rope 124 passes through the through hole and extends into the interior of the lamp pole 100) and extends downward along the lamp pole 100 to the lower end of the lamp pole 100.

[0047] Through the above exemplary implementation of this embodiment, when the recovery traction rope 124 is pulled downward at the lower end of the lamp pole 100, the seat body 108 is subjected to tension and slides along the guide rail 106 toward the upper end of the lamp pole 100, and then slides downward along the guide rail 106 to the lower end of the lamp pole 100.

[0048] In some exemplary implementations of this embodiment, a wiring channel 128 is provided inside the guide rail 106, and a notch 130 is provided on the side wall of the guide rail 106, and the notch 130 is located on the top side of the wiring channel 128. A traction block 132 is fixedly connected to the inner side wall of the slider 110, and the traction block 132 passes through the notch 130 and extends into the wiring channel 128. The end of the delivery traction rope 118 close to the seat body 108 is located in the wiring channel 128 and is fixedly connected to the traction block 132, and the end of the recovery traction rope 124 close to the seat body 108 is located in the wiring channel 128 and is fixedly connected to the traction block 132.

[0049] Through the above exemplary implementation of this embodiment, the recovery traction rope 124 is arranged in the wiring channel 128, which helps to improve the neatness of the recovery traction rope 124 and prevent the recovery traction rope 124 from being exposed to sunlight.

[0050] In some exemplary implementations of this embodiment, a plurality of drainage holes 134 are provided on the bottom surface of the wiring channel 128 , and the drainage holes 134 are evenly distributed along the guide rail 106 .

[0051] Through the above exemplary implementation of this embodiment, the drainage through hole 134 facilitates the drainage of rainwater flowing into the wiring channel 128 , which helps to avoid water accumulation in the wiring channel 128 .

[0052] In some exemplary implementations of this embodiment, a maintenance window 136 is provided on the side wall of the lower end of the lamp pole 100 , and the delivery traction rope 118 and the recovery traction rope 124 extend to the lower end of the lamp pole 100 and pass through the maintenance window 136 .

[0053] Through the above exemplary implementation of this embodiment, a window door is provided on the maintenance window 136, and the window door is locked on the lamp pole 100 using a lock. After the staff uses a key to open the window door, they pull the delivery traction rope 118 or the recovery traction rope 124 from the maintenance window 136, which helps to avoid non-staff from performing erroneous operations.

[0054] In some exemplary implementations of this embodiment, the delivery traction rope 118 and the recovery traction rope 124 are respectively equipped with power cord harnesses.

[0055] Through the above exemplary implementation of this embodiment, for example, the delivery traction rope 118 adopts a live wire harness, and the recovery traction rope 124 adopts a neutral wire harness. The wire harness can not only provide power to the lamp body 104, but also serve as a traction component for the staff to drive the seat body 108 to slide along the guide rail 106, and there is no need to set up an additional rope for traction.

[0056] The guide rail 106 is shaped as a quarter arc at the portion where the cantilever 102 and the lamp pole 100 are close to each other, which facilitates the base 108 to slide from the lamp pole 100 to the cantilever 102 or from the cantilever 102 to the lamp pole 100, thereby achieving smooth turning. At the same time, it can also serve as a diagonal brace for the cantilever 102, thereby improving the structural strength of the connection between the cantilever 102 and the lamp pole 100.

[0057] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
