[0002] Optoelectronic composite high-voltage cable is a transmission line suitable for broadband network systems.

The pore size ranges from nanometer to micrometer, and has a good fireproof effect, so that the cable can be more fire-resistant when in use, which not only improves the service life of the cable, but also avoids the leakage of the cable core 2. The surface of the fireproof shell 4 is provided with a PVC protective layer 6, under the action of the PVC protective layer 6, the fireproof shell 4 and its internal parts can be protected, which can not only isolate water and foreign matter, but also has a certain heat-resistant effect. The inner wall of the PVC protective layer 6 is fixedly connected with a connecting plate 7, and a connecting groove 5 is provided on the surface of the fireproof shell 4. The inner wall of the connecting groove 5 and the connecting plate 7 are connected. The surface of the fireproof shell 4 is fixedly connected, and under this action, the fireproof shell 4 can be blocked, so that it will not move easily, and the stability of the connection between the fireproof shell 4 and the PVC protective layer 6 is effectively improved. The number of connecting grooves 5 and connecting plates 7 is several, and they are all distributed in a circular array at the center of the fireproof shell 4. Under this action, the limiting effect of the fireproof shell 4 can be improved, so that the fireproof shell 4 will not move easily. The surface of the PVC protective layer 6 is provided with a fireproof layer 8, and the inner wall of the fireproof layer 8 is fixedly connected to the surface of the PVC protective layer 6. The fireproof layer 8 is phosphoric acid. Ammonium salt material has good fire resistance and will not easily burn, so as to protect the surface of the cable, thereby improving the fire resistance of the cable. The surface of the fireproof layer 8 is fixedly connected with a fixing ring 9, and the surface of the fixing ring 9 is provided with a mounting groove 10. A blocking mechanism 11 is installed inside the mounting groove 10. The blocking mechanism 11 can adjust its position according to gravity, so that the blocking mechanism 11 can block the bottom of the surface of the fireproof layer 8, thereby blocking the fire and preventing it from easily contacting the fireproof layer 8, thereby improving the fire resistance of the cable.

[0023] The blocking mechanism 11 includes a movable ball 111, the surface of the movable ball 111 is slidably connected to the inner wall of the mounting groove 10, the surface of the movable ball 111 is fixedly connected to a connecting rod 112, the surface of the connecting rod 112 is slidably connected to the inner wall of the mounting groove 10, the diameter of the movable ball 111 is larger than the diameter of the connecting rod 112, the mounting groove 10 is a T-shaped structure design, the mounting groove 10 is used in conjunction with the movable ball 111 and the connecting rod 112, under this action, the movable ball 111 can be moved inside the mounting groove 10 without being moved out from the inside, and under the action of the movable ball 111, the movable ball 111 can also be lowered to the mounting groove. 10 The friction between the inner walls makes the movable ball 111 smoother when moving. The bottom of the connecting rod 112 is fixedly connected with a protective plate 113. Under the action of the protective plate 113, the fire below can be blocked so that it will not easily contact the fireproof layer 8. The protective plate 113 is designed to be arc-shaped. The inner diameter of the protective plate 113 is larger than the outer diameter of the fireproof layer 8. Under this action, the fireproof layer 8 can be blocked, and with the cooperation of the movable ball 111 and the connecting rod 112, it can move freely according to its own gravity, so that the cable does not need to adjust the position of the protective plate 113 when in use.

[0024] It is worth noting that the technical features such as the battery cell 2 and the support block 1 proposed in this technical solution should be regarded as the prior art. The specific structure, working principle, and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, during installation, under the action of gravity, the protective plate 113 will slide inside the installation groove 10 through the cooperation of the connecting rod 112 and the movable ball 111 until the protective plate 113 is vertically downward, thereby protecting the fireproof layer 8. In the event of a fire, the protective plate 113 can block the fire below so that it will not easily contact the fireproof layer 8, thereby improving the fireproof effect of the cable. In the cooperation of the fireproof layer 8 and the fireproof shell 4, the fire can be further blocked, so that the cable will not easily expose the battery cell 2 to the outside when encountering a fire, thereby improving the safety of the cable when encountering a fire.
