[0028] An embodiment of the utility model provides a lightning protection device for a medium wave transmitting antenna.

[0030] Please refer again Figure 1 、 Figure 2 and Figure 3 A support mechanism 2 for reducing shaking is provided above the lightning protection outer box 1. The support mechanism 2 includes a fixed base plate 201. The inner wall of the fixed base plate 201 is fixedly connected with a damper 202. The setting of the damper 202 can provide resistance to the movement of the hinged sliding plate 203, thereby effectively consuming the movement energy of the hinged sliding plate 203.

[0031] The telescopic end of the damper 202 is fixedly connected to a hinged sliding plate 203, the outer surface of the hinged sliding plate 203 is slidably connected to the lightning protection outer box 1, and the inner wall of the hinged sliding plate 203 is hinged to a swing plate 204 through a pin shaft. When the swing plate 204 swings, it can effectively drive the hinged sliding plate 203 to slide in the inner wall of the fixed base plate 201.

[0032] A buffer spring 205 is sleeved on the outer surface of the damper 202, one end of the buffer spring 205 is fixedly connected to the hinged sliding plate 203, and the end of the buffer spring 205 away from the hinged sliding plate 203 is fixedly connected to the damper 202. When the hinged sliding plate 203 slides, it can effectively drive the two buffer springs 205 on both sides thereof to perform relative extension and contraction deformation, thereby effectively buffering the kinetic energy of the hinged sliding plate 203.

[0033] One end of the swing plate 204 away from the hinged sliding plate 203 is hinged to a hinged fixing ring 206 through a pin shaft. The inner wall of the hinged fixing ring 206 is fixedly connected to a lightning rod 207. The outer surface of the lightning rod 207 is fixedly connected to the lifting platform 301. The upper end of the lightning rod 207 is fixedly installed with a lightning tip and a lightning ball, which can effectively prevent lightning strikes.

[0034] The outer surface of the lightning rod 207 is slidably connected to the lightning connecting tube 208, one end of the lightning connecting tube 208 is fixedly connected to the lightning protection outer box 1, and one end of the lightning connecting tube 208 is fixedly connected to the down conductor 209, and the outer surface of the down conductor 209 is fixedly connected to the lightning protection outer box 1. By sliding the lightning rod 207 up and down in the inner wall of the lightning connecting tube 208, the lightning rod 207 can be effectively raised. By adjusting the lightning rod 207 to make its height higher than the medium wave transmission line 5, the probability of damage to the medium wave transmission line 5 in lightning and strong wind weather can be effectively reduced.

[0035] The outer surface of the fixed base plate 201 is fixedly connected with a support slide 210, and the end of the support slide 210 away from the fixed base plate 201 is slidably connected to the lightning protection outer box 1. Through the setting of the support slide 210, the fixed base plate 201 is effectively fixed and supported, making it more stable on the top surface of the lifting platform 301.

[0036] Please refer again Figure 1 and Figure 4 The interior of the lightning protection outer box 1 is provided with a protective mechanism 3 for lifting protection. The protective mechanism 3 includes a lifting platform 301. The top surface of the lifting platform 301 is fixedly connected to the fixed bottom plate 201. The outer surface of the lifting platform 301 is slidingly connected to the lightning protection outer box 1. The outer surfaces of the lightning protection outer box 1 and the lifting platform 301 are fixedly coated with anti-corrosion insulating material, which effectively improves the service life of the lightning protection outer box 1 and the lifting platform 301.

[0037] An electric push rod 302 is fixedly connected to the inner bottom wall of the lightning protection outer box 1, and the telescopic end of the electric push rod 302 is fixedly connected to the lifting platform 301. A control button of the electric push rod 302 is fixedly installed inside the lightning protection outer box 1. The control button is electrically connected to the wind speed sensor. When the wind speed sensor senses that the wind speed is accelerating, it can automatically turn on the electric push rod 302 to make it extend and retract up and down.

[0038] The bottom surface of the lifting platform 301 is fixedly connected with a blocking plate 303, the outer surface of the blocking plate 303 is slidably connected to the lightning protection outer box 1, the inner wall of the lifting platform 301 is fixedly installed with a cooling fan 304, and the inner bottom wall of the lightning protection outer box 1 is fixedly connected with the lightning protection inner box 305. Through the setting of the cooling fan 304, when it is sunny, the lifting platform 301 is moved downward to effectively blow air and dissipate heat to the signal transmission box 4. When there is thunder and lightning and strong winds, the lifting platform 301 drives the blocking plate 303 to move upward, which can effectively block the air inlet and outlet on the surface of the lightning protection outer box 1, so that the signal transmission box 4 is sealed and isolated from the outside world, thereby greatly improving the safety of the signal transmission box 4.

[0039] The inner wall of the lightning protection inner box 305 is fixedly connected to the signal transmission box 4, the top surface of the signal transmission box 4 is fixedly connected to the medium wave transmission line 5, the outer surface of the medium wave transmission line 5 is fixedly connected to the fixed sleeve 6, one end of the fixed sleeve 6 is fixedly connected to the lightning protection inner box 305, and the outer surface of the fixed sleeve 6 is slidably connected to the lifting platform 301. The setting of the fixed sleeve 6 effectively protects the medium wave transmission line 5, avoiding the phenomenon of damage to the medium wave transmission line 5 caused by friction when the lifting platform 301 slides up and down.

[0040] The electric push rod 302 in this application is a common electrical device in the prior art. This application will not go into too much detail about its model or internal structure, and it can also be replaced by other power sources.

[0041] Working principle: When encountering thunderstorm and strong wind weather, by turning on the operation of the electric push rod 302, it stretches and drives the lifting platform 301 to move upward in the inner wall of the electric push rod 302, and the lifting platform 301 moves upward and drives the lightning rod 207 to slide upward in the inner wall of the lightning connecting tube 208, so that the height of the lightning rod 207 is higher than the medium wave emission line 5, effectively making the lightning rod 207 guide the lightning and prevent the medium wave emission line 5 from being struck by lightning. When the lightning rod 207 shakes against the wind force, the swing plate 204 in the inner wall of the hinged fixing ring 206 will swing, and the swinging plate 204 drives the hinged sliding plate 203 to slide in the inner wall of the fixed bottom plate 201. Through the damping characteristics of the two dampers 202 on both sides of the hinged sliding plate 203 and the buffer spring 20 5 interacts with each other, thereby effectively slowing down the movement of the hinged sliding plate 203, making the lightning rod 207 more stable to guide the lightning, and effectively avoiding the shaking of the lightning rod 207, which causes its overall shape to bend and seriously affects the lightning protection effect. At the same time, during the upward movement of the lifting platform 301, the blocking plate 303 and the cooling fan 304 will move up at the same time. The upward movement of the blocking plate 303 will block the air inlet and outlet on the surface of the lightning protection outer box 1, so that the signal transmission box 4 is sealed and isolated from the outside world. By making the height of the medium wave transmission line 5 lower than the lightning rod 207 and the signal transmission box 4 closed and isolated, the signal transmission box 4 and the medium wave transmission line 5 are effectively protected to avoid damage caused by lightning strikes.
