[0039] Working principle: When a fire accident occurs somewhere and need to remind people to stay away from here, the firefighters turn on the car 1 and control the deceleration motor 14 to drive the third rotation rod 22 to rotate counterclockwise, and the second slider 18 is on the second slide rail 17. Moving to the left, the first rack 19 and the second rack 20 also move to the left, the first gear 12 rotates, the first rotating rod 10 also rotates, and the first indicator 13 rotates. When the first rotating rod 10 rotates at a certain angle, the first sliding block 15 moves downward on the first sliding rail 4, and the second rack 20 is located directly behind the second gear 8. The first rack 19 and the second rack The rack 20 also moves downward, the second gear 8 rotates, and the second indicator 9 also rotates accordingly. When the first rotating rod 10 rotates by a certain angle, the second sliding block 18 moves to the right on the second sliding rail 17 . After the first rotating rod 10 is rotated by a certain angle, the first sliding block 15 moves upward on the first sliding rail 4 and moves to the initial position. The third rotating rod 22 is continuously rotated counterclockwise, so that the first indicator 13 and the second indicator 9 can be continuously rotated, thereby attracting people's attention. At the same time, firefighters broadcast relevant news through loudspeaker 21, reminding people to pay attention, raising people's awareness of firefighting, and reminding people to stay away from the accident area, which improves people's safety.
[0040] Because the third bearing seat 11 is also included, the third bearing seat 11 is provided in the middle of the right side of the automobile 1, the first rotating rod 10 passes through the third bearing seat 11, the third bearing seat 11 is a thrust bearing seat, and the third bearing seat 11 and the middle part of the right side of the automobile 1 are vertically fixed and welded, and the third bearing seat 11 can enhance the stability of the first rotating rod 10 when it rotates, thereby improving the stability of the entire device.
[0041] Because it also includes a fourth bearing seat 23, a fourth bearing seat 23 is connected to the right side of the bottom of the vehicle 1, the second rotating rod 7 passes through the fourth bearing seat 23, the fourth bearing seat 23 is a deep groove ball bearing seat, and the fourth bearing seat 23 is a deep groove ball bearing seat. The bearing seat 23 and the right side of the bottom of the car 1 are vertically fixed and welded. The horizontal distance between the fourth bearing seat 23 and the right end of the bottom of the car 1 is 20 cm. The fourth bearing seat 23 can enhance the stability of the second rotating rod 7 when it rotates. Thus, the stability of the whole device is improved.
[0042] Because the LED lights 24 are also included, the first indicator 13 and the second indicator 9 are evenly provided with LED lights 24. The working voltage of the LED lights 24 is 220 volts, the power of the LED lights 24 is 5 watts, and the power of the LED lights 24 is 5 watts. The model is G-CL-5730, and the weight of the LED light 24 is 5 grams. When the light is not good, turn on the LED light 24. The LED light 24 can improve the recognition of the first sign 13 and the second sign 9, so that the Broadcast is better.
