The bottom of the semi-circular ring slider 26 contacts the inclined protrusion 25. A connecting rod 27 is fixed to the middle position of the top of the semi-circular ring slider 26. A fixing ring 28 is fixed to the top of the embedded part 10 in a left-right symmetrical manner. The connecting rod 27 slides upward from the fixing ring 28 to pass through the top of the embedded part 10. A fourth spring 30 is connected between the bottom of the semi-circular ring slider 26 and the bottom of the annular groove.
[0027] like Figure 2 and Figure 4-Figure 6As shown, the indicator light also includes a ventilation mechanism, which includes a ventilation pipe 11, a second servo motor 12, a gear 13, a slide rail 14, a gear ring 15, a traction rope 16, a waterproof cover 17, a breathable partition 18, a first spring 19, a support rod 20 and a telescopic rod 21. Several ventilation pipes 11 are buried circumferentially inside the embedded part 10. One end of the ventilation pipe 11 passes through the embedded part 10, and the other end of the ventilation pipe 11 passes through the bottom of the shell 2. The lower end opening of the ventilation pipe 11 is flush with the bottom of the shell 2. The second servo motor 12 is fixedly connected to the left side of the shell 2. The bottom of the output shaft of the second servo motor 12 is fixedly connected to the gear 13. The bottom of the shell 2 is fixedly connected to the slide rail 14. The slide rail 14 is slidably connected to the gear ring 15. A ventilation gap is left between the gear ring 15 and the lower end opening of the ventilation pipe 11. The wheel 13 is engaged with the ring gear 15. Several traction ropes 16 are fixed to the bottom of the ring gear 15 along the circumferential direction. The traction ropes 16 pass through the lower end of the ventilation pipe 11 and pass through the upper end of the ventilation pipe 11. A breathable baffle 18 is fixed to the upper side of the interior of the ventilation pipe 11 near the upper end outlet. Several support rods 20 are fixed to the top of the breathable baffle 18. A telescopic rod 21 is connected to the inside of the support rod 20 in an upward sliding manner. A waterproof cover 17 is fixed between the tops of the telescopic rods 21. The waterproof cover 17 is made of arc-shaped polypropylene. The top of the traction rope 16 is fixedly connected to the bottom of the waterproof cover 17. A first spring 19 is connected between the waterproof cover 17 and the middle of the breathable baffle 18. The support rod 20 surrounds the outside of the first spring 19. The first servo motor 6, the thermal sensor 9 and the second servo motor 12 are all electrically connected to the controller 7.
[0028] like Figure 9 As shown, the indicator light further includes a fixing member 29 . Circular holes are provided in the middle of the connecting rod 27 and the fixing ring 28 . The fixing member 29 is inserted into the connecting rod 27 and the fixing ring 28 through the circular holes.
[0029] When installing the indicator light, first dig a circular pit on the ground, bury the embedded part 10 in the circular pit, put the shell 2, lamp panel 4 and lamp beads 5 and other components into the embedded part 10, the second spring 22 is compressed by the bottom of the shell 2, and the lamp beads 5 light up and shine upward, thereby helping the aircraft to accurately locate the corresponding runway during flight. When the lamp beads 5 start to heat up after long-term use, the thermal sensor 9 detects the high temperature and then transmits the high temperature signal to the controller 7. The controller 7 controls the first servo motor 6 to start, and the output shaft of the first servo motor 6 drives the fan 8 to rotate. The fan 8 draws the hot air in the lampshade 1 downward into the shell 2, and the hot air is dissipated to the outside through the open ventilation pipe 11. At the same time, some external gas can also enter the embedded part 10 from the ventilation pipe 11, and the external gas in the embedded part 10 enters the lampshade 1 from the circular air vent 3, thereby realizing gas circulation, dissipating heat inside the indicator light, and drying water vapor that accidentally penetrates into the lampshade.
[0030] In rainy weather, the controller 7 is remotely controlled to start the second servo motor 12 through the controller 7. The output shaft of the second servo motor 12 drives the gear 13 to rotate, and the gear 13 engages with the ring gear 15 to drive the ring gear 15 to rotate. One end of the traction rope 16 follows the ring gear 15 and pulls the waterproof cover 17 downward. At this time, the telescopic rod 21 is retracted into the support rod 20, the first spring 19 is compressed, and the waterproof cover 17 and the ventilation pipe 11 form a closed space. In thunderstorm weather, rainwater falls on the surface of the arc lampshade 1 and slides onto the ground, thereby draining water. The evacuated rainwater is isolated from the outside by the waterproof cover 17 and will not enter the ventilation pipe 11.
[0031] When the component is damaged and needs to be replaced, the traction rope 16 fixed to the waterproof cover 17 is disconnected, the fixing piece 29 is pulled out from the circular hole of the connecting rod 27 and the fixing ring 28, and the connecting rod 27 is pressed downward to drive the semi-circular ring slider 26 to move downward. The fourth spring 30 is compressed, and the bottom of the semi-circular ring slider 26 squeezes the inclined protrusion 25, so that the block 24 moves outward, the third spring 23 is compressed, and the block 24 is pushed back into the slot and no longer blocks the housing 2. The second spring 22 rebounds, and the housing 2, the lamp panel 4 and the lamp beads 5 and other components pop out from the embedded part 10. The repaired component is placed in the embedded part 10, the second spring 22 is compressed, the fourth spring 30 rebounds, the semi-circular ring slider 26 is reset, the third spring 23 rebounds, and the block 24 is stuck in the groove on the upper part of the housing 2. The fixing piece 29 is re-inserted to fix the housing 2, the traction rope 16 is passed through the upper end of the ventilation pipe 11, and the top of the traction rope 16 is connected to the waterproof cover 17. In this way, the indicator light can be quickly disassembled or replaced.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
