[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, the utility model provides an emergency broadcast terminal with lightning protection, including a column 2, a broadcaster 3 is fixedly provided on the top of the column 2, the broadcaster 3 receives signals for broadcasting, a connecting column 6 is fixedly provided on the top of the broadcaster 3, and the connecting column 6 is provided with an insulating material to protect the broadcaster 3 below, and a protective shed 4 is fixedly provided on the top of the connecting column 6. The protective shed 4 protects against rainwater and prevents rainwater from seeping in. The protective shed 4 can be provided in a plastic cone shape, and a lightning protection component 5 is also provided on the top of the protective shed 4.

[0027] The lightning protection assembly 5 includes a positioning seat 51 fixedly set on the top of the protective shed 4, and a rod 52 is inserted inside the positioning seat 51. A circular plate 54 is fixedly set on the top of the rod 52, and a fuse column 57 is fixedly set on the top of the circular plate 54. The fuse column 57 is made of a material with a low melting point, such as lead-antimony alloy. An insulating cover 55 is fixedly set on the top of the fuse column 57 to isolate the lightning rod 56 above and the broadcaster 3 below. The lightning rod 56 is fixed on the top of the insulating cover 55, and an anti-slip ring 14 is fixedly set on the bottom side of the insulating cover 55. The anti-slip ring 14 is connected to the lightning protection cable 7 to guide the lightning. The bottom end of the anti-slip ring 14 is fixedly provided with the lightning protection cable 7, and the other end of the lightning protection cable 7 is fixedly provided with a grounding block 10, which is released through the grounding block 10.

[0028] Specifically, a base 1 is fixedly provided at the bottom end of the column 2 and cast with cement. The base 1 is cast on the ground surface, and the grounding block 10 is buried in the ground. The base 1 casts the column 2 above.

[0029] The outer side of the insertion rod 52 is provided with a spring 53 that fits on the top surface of the positioning seat 51, and the spring 53 fits with the circular plate 54. The fuse column 57 is set to a symmetrical cone structure, and the middle position is thinner, which is more convenient for rapid melting and disengagement under high temperature conditions. The middle position of the fuse column 57 is made of high-temperature fuse material. The outer side of the lightning protection cable 7 is provided with a shell 15 fixed to the insulating cover 55. The inside of the shell 15 is provided with a spring 2 8 that is sleeved on the outside of the lightning protection cable 7. The spring 2 8 structure can be set inside the shell 15 to provide auxiliary support for the lightning protection cable 7 and the anti-slip ring 14 above to prevent disengagement.

[0030] The top of the second spring 8 is fitted with an anti-slip plate 9 fixed to the lightning protection cable 7. The anti-slip plate 9 structure can contact the second spring 8 for stabilization to prevent the lightning protection cable 7 from detaching from the inside of the outer shell 15. The lightning protection cable 7 is slidably arranged near the outer side of the protective shed 4 and is fixed to the protective shed 4 with a positioning frame 11. The positioning frame 11 limits the lightning protection cable 7 to prevent it from falling off. A third spring 13 is fixed between the top notches of the positioning frame 11. A positioning ring 12 slidingly arranged with the lightning protection cable 7 is fixed at the middle position of the third spring 13. The third spring 13 is connected to the lightning protection cable 7 through the positioning ring 12 for traction and limiting, thereby buffering the shaking of the lightning protection cable 7.

[0031] The broadcaster 3 receives wireless signals to broadcast information, which is a prior art technology and will not be described in detail. Meanwhile, the present invention also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its operating principle is a well-known technology. The model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0032] Working principle and process:

[0033] The staff completed the casting of the base 1 and buried the grounding block 10 in the ground. The lightning protection cable 7 was connected to the bottom of the lightning protection component 5 for lightning diversion. When lightning hits the top of the broadcaster 3, the lightning can be guided by the lightning rod 56 through the lightning protection cable 7 passing through the bottom of the insulating cover 55 to guide the lightning into the grounding block 10 buried in the ground, thereby protecting the broadcaster 3. When the intensity of the lightning bombardment is too large or lightning escapes, the high temperature generated by the escaped lightning will quickly melt in the process of passing through the fuse column 57. The broken fuse column 57 cooperates with the insulating cover 55 structure below to increase the resistance of lightning in the conductive medium, thereby reducing the occurrence of further lightning escape to the broadcaster 3 below, protecting the broadcaster 3 on the lower column 2, and the protective shed 4 can also enhance the protection effect.

[0034] When an external force pulls the lightning protection cable 7, the anti-slip ring 14 inside the lightning protection cable 7 positioning frame 11 is used to limit the position, and the spring three 13 structure is used to pull and restrain the lightning protection cable 7, reducing the risk of the lightning protection cable 7 falling. The lightning protection cable 7 can be squeezed by the anti-slip plate 9 inside the shell 15 to deform the spring two 8 on the outside of the lightning protection cable 7, which can effectively reduce the deviation caused by the shaking of the lightning protection cable 7, and also avoid direct connection too tight, which may cause the lightning protection cable 7 to break directly.
