Working process and principle: when the semi-trailer is running normally, the air injection mechanism 5 is shrunk in the storage slot 14, and the rectangular block 3 is completely shrunk in the storage slot 2. When the semi-trailer is turning, firstly, the first motor 41 starts to drive the locking lever 42 Rotate in the upper rotation groove 43 and the lower rotation groove 44, when the locking lever 42 rotates to the center position of the fixed block 47 and the center position of the sliding groove 46 are in the same straight line, the first motor 41 stops rotating, and at this moment the second motor 41 is started. The three motors 9 drive the gear 10 to rotate, and then drive the rectangular block 3 to move outward through the gear bar on the moving plate 7. At the same time, the fixed block 47 slides on the sliding groove 46. When the storage grooves 14 on the rectangular block 3 are all moved to the storage groove 2 outside, the third motor 9 stops rotating, and then starts the cylinder 51, the output shaft of the cylinder 51 drives the lifting plate 51 to move downward, when the lifting plate 51 is completely moved out to the outside of the storage tank 14, the cylinder 51 stops, and at this time, the cylinder 51 is opened. The second air valve 13 also closes the first air valve 12, and the exhaust gas in the exhaust pipe 11 will enter the air injection pipeline 55 along the heat-resistant air pipe, and then, the exhaust gas will be ejected along the air injection port 56, like this , will form an uninterrupted outward erupting hot air flow on both sides of the trailer plate 1, and start the second motor 57 at this time, which will drive the air spray bar 53 to rotate, and the second motor 57 will continue to rotate 30 degrees back and forth, heat The airflow will also swing in such a range. When pedestrians enter this range, they will feel the smell of hot airflow and exhaust gas, so they will notice the driving route of the semi-trailer and take evasive measures in time. The water enters the water spray pipe 61, and is sprayed vertically to the ground by the high-pressure nozzle 62 to form a water column. When the LED color light 63 is turned on, the light of the LED color light 63 passes through the water column to make the water column present a certain color, which can even cause pedestrians to panic. Note that when driving at night, such colored light beams can remind pedestrians in time. When turning and driving on a normal road surface, first turn off the LED lights 63 and the water tank of the semi-trailer, and then open the first air valve 12 and close the second. After the air valve 13 is completed, the second motor 57 drives the air spray rod 53 to return to the original position and then closes, and then starts the air rod 51 to bring the lifting plate 52 back to the original position and then closes, and finally the third motor 9 starts to shrink the rectangular block 3 In the storage groove 2, the fixed block 47 returns to the locking groove 45, and at this moment, the first motor 41 is started to drive the locking lever 42 to rotate 90 degrees, and the fixed block 47 is completely in the locking groove 45 and does not slide Groove 46 is connected, like this, can prevent vehicle from shaking, and rectangular block 3 is shaken out of receiving groove 2.

Based on the above, adopting the semi-trailer with turning reminding function of the present invention, by setting the air spray mechanism and the water spray mechanism on both sides of the semi-trailer, when the semi-trailer is turning, the air spray mechanism and the water spray mechanism are activated, so that pedestrians can walk within half a distance. The driving situation of the semi-trailer can be noticed when the trailer is at a safe distance, so that avoidance measures can be taken in time, which solves the risk of pedestrians being involved in the bottom of the vehicle and protects the safety of personnel.

It can be known from common technical knowledge that the present invention can be realized through other embodiments without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are embraced by the present invention.
