[0019] In summary, the complete workflow and principle of the present invention are as follows: Process 1: First, when a thief approaches the traffic signal cabinet 1 to steal, at this time, an identification camera 14 is installed above the traffic signal cabinet 1. The identification camera 14 can be used to automatically identify human faces. When non-related staff members approach, the identification camera 14 will capture the picture and transmit the signal from the controller to the electromagnet 23, that is, the electromagnet 23 is powered on at this time, and then the electromagnet 23 generates a large magnetic force and quickly absorbs the anti-theft cover 24 slidably connected to the slide rail 21 upwards, so that through the real-time monitoring of the identification camera 14 and the controller and the emergency treatment of the anti-theft cover 24, the anti-theft cover 24 is used to quickly cover the locking area 13, and the source protection is carried out from the place where the thief is easy to start, so that the thief cannot start from the locking area 13, thereby improving the safety of the traffic signal cabinet 1 and reducing the risk of theft; Process 2: At the same time, when the anti-theft cover 24 rises, it will synchronously drive the pin 32 located in front of it to rise synchronously, and when the anti-theft cover 24 completely covers the locking area 13, the pin 32 is now completely inserted into the interior of the locking cavity 31.

Note: The lock ball 35 is magnetic and will drive the lock core 34 compression spring to move upward along the inner wall of the locking cavity 31. As the pin 32 is gradually inserted, the lock ball 35 moves to both sides and embeds The inside of the ball groove 36, and when the engaging portion 33 at the lower end of the pin 32 gradually moves to between the locking balls 35, since the opposing surfaces at the upper and lower ends of the engaging portion 33 are both inclined surfaces, under the negative elastic force of the spring, the locking ball 35 is matched to the engaging portion 33, that is, the locking is completed, that is, the anti-theft cover 24 is completed quickly after the emergency action is completed, thereby improving the firmness of the anti-theft cover 24 after being adsorbed on the electromagnet 23, preventing thieves from trying to open the anti-theft cover 24 again, and further improving the safety of the traffic signal cabinet 1; When the relevant staff needs to unlock the anti-theft cover 24, the staff puts a magnet above the locking cavity 31, so that under the adsorption effect of the magnet and the lock ball 35, the lock core 34 and the lock ball 35 are gradually compressed and the spring is raised, and then under the cooperation of the locking part 33 and the lock ball 35, the unlocking is automatically completed.

[0020] As shown in the process three, the buffer power mechanism 4 is symmetrically arranged on the left and right sides of the traffic signal cabinet 1. In this illustration, the buffer power mechanism 4 is closer to the traffic signal cabinet 1 in consideration of the aesthetics of the drawing. However, in the actual use process, the buffer power mechanism 4 can be arranged farther away from the traffic signal cabinet 1. Since the traffic signal cabinet 1 is generally installed near a road intersection and there are often vehicles passing by, when a vehicle drives to the semi-arc cavity plate 41, the semi-arc cavity plate 41 will warn the driver to appropriately reduce the speed at this point, thereby reducing the possibility of traffic accidents caused by excessive speed, thereby reducing the accidental damage to the traffic signal cabinet 1, thereby improving the safety of the environment where the traffic signal cabinet 1 is located on the road; When the vehicle passes over the top of the semi-arc cavity plate 41, it will press each group of piston spring arc plates 45 to move downward. In the process of the piston spring arc plates 45 moving downward, the springs will be compressed and under the cooperative connection between the connecting piece 2 44 and the connecting piece 1 43, the connecting piece 2 44 will convert the downward movement into a movement that drives the rotating shaft 42 to rotate. After being pressed down once, the piston spring arc plate 45 will automatically reset upward again under the negative elastic force of the spring. After completing a cycle of pressing down and resetting, the rotating shaft 42 will complete the rotation movement. Since the intersection of the rotating shaft 42 and the transmission shaft 47 is equipped with a bevel gear 1, and the outer end of the transmission shaft 47 is meshed with the bevel gear 1 on the rotating shaft 42 through the bevel gear 2, that is, the rotating shaft 42 can be connected to the transmission shaft through the bevel gear 1. 47 is matched with the transmission, so at this time the rotating shaft 42 drives the transmission shaft 47 to rotate synchronously, and then because bevel gear three is installed at the lower end of the heat dissipation fan 48, and bevel gear four is meshed below the bevel gear three, and the bevel gear four is fixedly installed on the inner end of the transmission shaft 47, that is, the transmission shaft 47 drives the bevel gear three to transmit through the bevel gear four, that is, drives the heat dissipation fan 48 to rotate, so that the heat dissipation fan 48 rotates at this time, and when the heat dissipation fan 48 rotates, an upward airflow is generated, and the airflow flows into the interior of the traffic signal cabinet 1 through the heat dissipation grille 15, so that the airflow generated by the heat dissipation fan 48 assists the interior of the traffic signal cabinet 1 to effectively dissipate heat, thereby improving the heat dissipation of the traffic signal cabinet 1 during operation and the stability of the working of the internal components.
