[0015] In some embodiments, the residual line well is a rectangular parallelepiped structure.

[0016] In some embodiments, a cable maintenance platform is provided on the terminal tower body.

[0017] The beneficial effects of the technical solution provided by this application include:

[0018] An embodiment of the present application provides a novel cable terminal tower downline system, comprising a terminal tower body, a bracket group and a residual wire well; the bracket group is arranged in multiple layers at intervals along the height direction of the terminal tower body, and each layer of the bracket group includes at least two cable brackets arranged at an angle, and the angle between each of the cable brackets located above is greater than the angle between each of the cable brackets located below, and the cable brackets are all arranged on the same side of the terminal tower body; the residual wire well is arranged at the bottom of the terminal tower body, and the residual wire well is located on the side where the cable bracket is located.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a novel cable terminal tower downline system, which can solve the problem in the related art that the cable terminal tower downline system has a large overall footprint.

[0031] See also Figures 1 to 5 As shown, an embodiment of the present application provides a novel cable terminal tower downline system, comprising a terminal tower body 1, a bracket group and a residual wire well 3; the bracket group is arranged in multiple layers at intervals along the height direction of the terminal tower body 1, and each layer of the bracket group includes at least two cable brackets 2 arranged at an angle, and the angle between each cable bracket 2 located above is greater than the angle between each cable bracket 2 located below, and the cable brackets 2 are all arranged on the same side of the terminal tower body 1; the residual wire well 3 is arranged at the bottom of the terminal tower body 1, and the residual wire well 3 is located on the side where the cable bracket 2 is located.

[0032] In actual use, since there are multiple layers of bracket groups arranged at intervals along the height direction on the terminal tower body 1, each layer of bracket groups includes at least two cable brackets 2 set at an angle, and the angle between each cable bracket 2 located at the top is greater than the angle between each cable bracket 2 located at the bottom, so that when the cable is fixed on the terminal tower body 1, the distance between the two rows of cables from top to bottom gradually decreases, and each cable bracket 2 is set on the same side of the terminal tower body 1. When the cable reaches the ground, the two rows of cables can be in contact with each other side by side. At this time, a surplus wire well 3 is set at the bottom of the terminal tower body 1 on the same side as the cable bracket 2 to accommodate the cable. In this way, the fence 7 only needs to be set in a small circle around the bottom of the terminal tower body 1. While the cables are well stored, the area occupied by the fence 7 is reduced, so that the overall floor space of the cable terminal tower offline system is reduced to a very small range.

[0033] Specifically, the cable supports 2 on the terminal tower body 1 are usually arranged in multiple layers in a "one" shape, that is, the cable supports 2 are arranged in multiple layers at intervals along the height direction of the terminal tower body 1, and each layer is provided with two cable supports 2 arranged at 180 degrees. In this way, a circle of residual cable trenches are usually arranged around the bottom of the terminal tower to place and store cables, and in order to prevent potential safety hazards, a circle of walls 7 are arranged around the residual cable trenches to prevent others from entering. In this way, the area occupied by this circle of walls 7 will be relatively large, which may have a certain impact on the architectural layout of the city.

[0034] However, the cable supports 2 of the new cable terminal tower offline system of the present application are not all arranged in an "I" shape. The two cable supports 2 on each layer are arranged at an angle, and the angle between the two cable supports 2 on the lower layer is smaller than the angle between the two cable supports on the upper layer. The two cable supports 2 on the lowest layer are at an acute angle, that is, the angle is small, which can make the distance between the cables at both ends continuously decrease from top to bottom. When they reach the ground, the cables at both ends can be gathered together and stored in the residual wire well 3 at the bottom of the terminal tower. In this way, the wall 7 only needs to be set around a smaller circle at the bottom of the terminal tower, and it is only necessary to surround the opening of the residual wire well 3, that is, the place where the cable is exposed, and the part close to the terminal tower. The area of ​​the wall 7 can be reduced, that is, the overall footprint of the cable terminal tower offline system is reduced.

[0035] In actual use, the cable supports 2 of each layer are arranged on the same side of the terminal tower body 1, and the residual wire well 3 is also arranged on the side where the cable supports 2 are located, so as to ensure the rationality of the implementation of the scheme.

[0036] In some alternative embodiments, see Figure 2 and Figure 6As shown, the wellhead of the spare line well 3 faces the direction of the terminal tower body 1, and the wellhead faces the direction of the cable downline, which can ensure that the distance between the spare line well 3 and the terminal tower body 1 is small, thereby reducing the area of ​​the wall 7. The spare line well 3 is a rectangular parallelepiped structure, buried underground, which is convenient for accommodating cables.

[0037] See also Figure 2 As shown, a lower cable trench 6 is provided between the remaining cable well 3 and the terminal tower body 1. The lower cable trench 6 is a small cable trench for placing cables provided at the bottom of the terminal tower body 1 and located on the same side as the cable support 2. The cables at the bottom of the terminal tower body 1 can be bundled and placed so as to be stored in the remaining cable well 3.

[0038] In actual use, see Figures 3 to 5 As shown, each layer of the bracket group includes two cable brackets 2, the two cable brackets 2 on the top layer are arranged at 180 degrees, and the two cable brackets 2 on the bottom layer are arranged at an acute angle. In some optional embodiments, the bracket group is provided with at least three layers. Figure 3 , the two uppermost cable supports 2 are arranged 180° apart, such as Figure 4 The two cable supports 2 at the lower layer may form an obtuse angle, and as the height decreases, the angle between the two cable supports 2 decreases successively, which can ensure that the distance between the cables at both ends is continuously reduced, so that the cables at both ends are continuously brought closer, such as Figure 5 The two cable supports 2 at the bottom are arranged at an acute angle, and the distance between the two cables is minimized, so as to facilitate the gathering of the two cables at the bottom.

[0039] In some alternative embodiments, see Figures 1 to 5 As shown, the cable support 2 includes a support rod 21 fixedly connected to the terminal tower body 1 and a limit assembly 4 arranged at one end of the support rod 21 away from the terminal tower body 1, and the limit assembly 4 is used to limit the cable. In actual use, the limit assembly 4 includes a fixed rod 41 vertically fixed to the support rod 21 and a plurality of limit members 42 arranged along the length direction of the fixed rod 41. The limit member 42 is a clamp. The setting of the clamp can better limit the cable and ensure its stability. In addition, a cable maintenance platform 5 is provided on the terminal tower body 1 to facilitate later maintenance operations.

[0040] In summary, the new cable terminal tower downline system of the present application includes a terminal tower body 1, a bracket group and a residual wire well 3; the bracket group is arranged in multiple layers along the height direction of the terminal tower body 1, and each layer of the bracket group includes at least two cable brackets 2 set at an angle, and the angle between each cable bracket 2 located above is greater than the angle between each cable bracket 2 located below, and the cable brackets 2 are all arranged on the same side of the terminal tower body 1; the residual wire well 3 is arranged at the bottom of the terminal tower body 1, and the residual wire well 3 is located on the side where the cable bracket 2 is located. Since multiple layers of bracket groups are arranged at intervals along the height direction on the terminal tower body 1, each layer of bracket groups includes at least two cable brackets 2 arranged at an angle, and the angle between each cable bracket 2 located at the top is greater than the angle between each cable bracket 2 located at the bottom, so that when the cable is fixed on the terminal tower body 1, the distance between the two rows of cables from top to bottom gradually decreases, and each cable bracket 2 is arranged on the same side of the terminal tower body 1. When the cable reaches the ground, the two rows of cables can be in contact with each other side by side. At this time, a surplus wire well 3 is arranged at the bottom of the terminal tower body 1 on the same side as the cable bracket 2 to accommodate the cable. In this way, the enclosure 7 device only needs to be arranged in a small circle around the bottom of the terminal tower body 1, which can reduce the area of ​​the enclosure 7 while accommodating the cables.

[0041] The cable supports 2 of the new cable terminal tower downline system of the present application are not all arranged in an "I" shape. The two cable supports 2 on each layer are arranged at an angle, and the angle between the two cable supports 2 on the lower layer is smaller than the angle between the two cable supports on the upper layer. The two cable supports 2 on the lowest layer are at an acute angle, that is, the angle is small, which can make the distance between the cables at both ends continuously decrease from top to bottom. When they reach the ground, the cables at both ends can be gathered together and stored in the residual wire well 3 at the bottom of the terminal tower. In this way, the wall 7 only needs to be set around the smaller circle at the bottom of the terminal tower. It is only necessary to surround the opening of the residual wire well 3, that is, the place where the cable is exposed, and the part close to the terminal tower. The area of ​​the wall 7 can be reduced, that is, the overall footprint of the cable terminal tower downline system is reduced.
