The middle part of the spring sheet will be lifted up due to the temperature increase, and the spring sheet triggers the second switch to cut off the power of the electromagnet, thereby causing the electromagnet to lose its repulsive effect on the magnetic block. The resetting of the spring causes the reset of the limit block, thereby causing the limit block to enter the fixed frame, and the limit block fails to limit the heat collecting plate. The heat collecting plate moves downward, thereby causing the cross plate to move downward. When the cross plate abuts against the top of the guide bar, the trigger rod touches the first switch to cause the second motor to operate, and the output shaft of the second motor rotates to drive the winding drum to rotate, and the winding drum pays off the rolling curtain. The rolling curtain moves under the action of the counterweight bar and closes the carport. When the counterweight bar moves to the bottom, the third switch in the counterweight bar contacts the trigger block, thereby causing the first motor to operate. 2. In the present invention, when the first motor is running, the output shaft of the first motor rotates to drive the rotating drum to rotate, and at the same time, the two rotating drums are rotated through the pulley and the belt. The rotation of the rotating drum causes the protrusion to move on the guide groove, and then the mounting block drives the connecting pipe to reciprocate. The connecting pipe diverts the water in the water tank transported by the hose to multiple nozzles for spraying. The nozzles spray the outside of the roller shutter to cool it down. At the same time, the fire-fighting agent in the fire-extinguishing agent storage tank is sprayed through the nozzle to extinguish the fire inside the carport, thereby isolating the fire in the electric carport and preventing the fire from spreading.

[0020] Working principle: In normal use, the electromagnet 33 is energized and the magnetic poles produced are the same as those of the magnetic block 34; In the present application, when the electric vehicle in the roof 5 catches fire, the temperature in the roof 5 rises, and the heat is collected by the heat collecting plate 6, thereby increasing the temperature of the spring piece 27. The middle part of the spring piece 27 will be lifted up due to the temperature increase, and the spring piece 27 triggers the second switch 47 to cut off the power of the electromagnet 33, so that the repulsive effect of the electromagnet 33 on the magnetic block 34 fails, and the reset of the spring 31 resets the limit block 30, thereby causing the limit block 30 to enter the fixing frame 32, and the limit block 30 fails to limit the heat collecting plate 6.

When the counterweight bar 24 moves to the bottom, the third switch 49 in the counterweight bar 24 contacts the trigger block 7, thereby operating the first motor 43. In the present application, when the first motor 43 is running, the output shaft of the first motor 43 rotates to drive the rotating drum 41 to rotate, and at the same time, the two rotating drums 41 are rotated through the pulley 42 and the belt. The rotation of the rotating drum 41 causes the protrusion 39 to move on the guide groove 40, and then the mounting block 36 drives the connecting pipe 15 to reciprocate. The connecting pipe 15 diverts the water in the water tank 13 transported by the hose 14 to multiple nozzles 16 for spraying. The nozzle 16 sprays and cools the outside of the roller shutter 22.
