[0002] As a core guarantee for safe operation, the communication system of passenger ropeways is frequently exposed to high-thunderstorm environments such as high mountains and canyons. Current lightning protection solutions mostly employ:

[0036] First Embodiment

[0037] Please refer to Figure 1-4 This embodiment provides a lightning protection device for a passenger ropeway communication line, including an inner frame and modular lightning protection components installed within the inner frame.

[0038] The inner frame 110 has an open-top frame structure, with longitudinally extending grooves 111 on both inner walls. The inner frame 110 is equipped with a pair of assembly guide rails 120. On the left side of the assembly guide rails 120, a convex slider 121 is provided that slides in conjunction with the groove 111, and on the right side, multiple assembly slots 122 are arranged in a linear array. Specifically, the longitudinal groove 111 has a T-shaped groove structure, and the convex slider 121 is equipped with T-shaped protrusions that match the cross-sectional shape of the T-shaped groove.

[0039] The assembly slot 122 is a stepped rectangular slot, including a wide upper slot and a narrow lower slot. All corners of the slot are rounded to avoid stress concentration and facilitate the fixing of the double-row connectors and the intermediate partition block, making it easy to plan the assembly area. The top opening is closed by a removable top cover 112, which is connected to the side wall of the inner frame 110 via clips or screws, allowing for easy assembly and removal of the assembly guide rail 120 to adapt to the position of the internal modular lightning protection components. The back panel of the inner frame 110 has a metal heat sink 130 with heat dissipation fins to actively dissipate heat from the heat-generating units. To further improve the heat dissipation effect of the protection device, a fan can also be installed in the inner frame 110; if necessary, the fan can be activated to accelerate heat dissipation.

[0040] The modular lightning protection safety component includes a security wiring module 140, a security unit module 150 disposed within and electrically connected to the security wiring module 140, a double-row connector 170 electrically connected to the security wiring module 140, and an intermediate partition block 160 for cable management.

[0041] In this embodiment, a pair of intermediate partition blocks 160 are provided. At both ends of the intermediate partition blocks 160 are fixing blocks 161 that engage with the mounting slots 122. The shape of the fixing blocks 161 perfectly matches the shape of the mounting slots 122. Multiple equally spaced cable management holes 162 are arranged horizontally inside to ensure physical isolation between high-voltage and low-voltage cables. Each cable management hole 162 has a corresponding hinged cable management door 163. One end of the hinged cable management door 163 is hinged to the open sidewall of the cable management hole 162, and the opposite end engages with the cable management hole 162. When organizing the cable bundle, the hinged cable management door 163 can be opened for organization, avoiding problems such as narrow perforation positions, difficulty in passing the cable bundle, or accidental damage to the cable ends during the threading process.

[0042] The inner wall of the cable management hole 162 is also equipped with a silicone anti-wear bushing 164, and the inner side of the hinged cable management door 163 is also equipped with a silicone anti-wear bushing 164 to protect the cable harness, realize visual management of opening and closing, and avoid cable bending damage. An electromagnetic isolation baffle is also installed between adjacent cable management holes 162 to enhance protection and block electromagnetic interference between cables.

[0043] In this embodiment, two safety wiring modules 140 are provided, making them suitable for use in large cableways. Multiple elastic locking blocks 141 are provided on both sides to engage with the mounting slots 122. During assembly, the elastic locking blocks 141 pop out to lock the safety wiring module 140 into the lower narrow slot. When removal is needed, the safety wiring module 140 is lifted upwards, releasing the elastic locking blocks 141 into the upper wide slot, allowing for easy replacement of the safety wiring module 140. The structure of the elastic locking blocks 141 is not limited; it can be the simple spring structure disclosed in this embodiment, or a slightly more complex elastic buckle structure, as long as the elastic locking blocks 141 can retract or partially retract into the safety wiring module 140.

[0044] The front of the security wiring module 140 is provided with a rectangular array of 10x10 distributed wiring troughs 142. For ease of use, horizontal and vertical coordinates 143 are also provided in the security wiring module 140 to facilitate counting the installed security unit modules 150. Each wiring trough 142 is equipped with one security unit module 150, and the wiring trough 142 and the security unit module 150 are plug-in connected. The wiring trough 142 of the security wiring module 140 has an embedded shielding layer, which is connected to the grounding port of the inner frame 110 through a grounding terminal to enhance protection, eliminate electrostatic coupling, and conduct induced lightning current.

[0045] The double-row connector 170 is fixedly installed in the middle of the two assembly guide rails 120. The intermediate partition block 160 and the security wiring module 140 are symmetrically distributed vertically around the double-row connector 170, forming a modular assembly unit. The double-row connector 170 is provided with double-row interfaces 171 symmetrically arranged vertically based on the horizontal centerline. Each row of interfaces is symmetrically distributed at equal intervals, which can bidirectionally expand the capacity of the lightning protection unit and adapt to cableway stations of different sizes.
