[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Place the electronic control equipment in a protective box. Start multiple cooling fans to effectively accelerate air circulation. Use the filter to effectively prevent dust from entering the protective box. Pull the filter and the square sleeve off the surface of the square mounting plate, release the four elastic snap-in grooves and the four elastic snap-in strips, and remove the filter for cleaning.

[0024] 2. When the temperature of the electronic control equipment in the protective box is high and the cooling fan cannot effectively dissipate heat, the first drive motor can be started to drive the rotating rod to rotate. The rotating rod rotates to drive the first slider to perform circular motion. The first slider performs circular motion while sliding back and forth in the first slide groove. Since the position of the first slider is limited by the first slide groove, the circular motion of the first slider is a change in the horizontal position and the vertical position. The horizontal motion of the first slider can be completed by sliding in the first slide groove, but the vertical motion of the first slider cannot be performed in the first slide groove. Since the reciprocating plate is slidably connected to the circumferential surface of the two third limit rods When the first slider moves longitudinally, it will drive the reciprocating plate as a whole to perform reciprocating linear motion on the circumferential surface of the two third limit rods, thereby achieving the purpose of the reciprocating plate driving the two push plates to perform reciprocating linear motion. The push plate performs reciprocating linear motion to drive the connecting plate and the piston to perform linear reciprocating motion in the air bin through the push rod. The piston moves to one side in the air bin to extract the hot air in the protection box through multiple air inlet pipes and air inlet cylinders and store it in the air bin. When the piston moves to the other side in the air bin, it squeezes the hot air stored in the air bin and discharges it through multiple air outlet pipes and air outlet cylinders. The hot air in the protection box can be discharged faster to achieve the purpose of heat dissipation.

[0025] 3. On rainy days or when the sunlight intensity is too high, you can turn the hand-tightened screw head to drive the drive screw to rotate. The drive screw rotates to drive the L-shaped plate to move. The L-shaped plate moves outward to drive the stretching plate to stretch the awning to unfold, so that the awning can cover the protection box and the outer edge of the protection box, which can prevent rainwater from leaking into the protection box, and can also prevent direct sunlight from shining on the protection box and causing a high temperature inside the protection box.

[0026] In the present invention, multiple cooling fans are used to replace traditional cooling ports to dissipate heat, which accelerates the air circulation in the protective box and increases the heat dissipation effect. At the same time, the setting of the air filter mechanism can effectively prevent external dust from entering the protective box. At the same time, the setting of the exhaust mechanism can cooperate with multiple cooling fans to dissipate heat when the temperature is high, effectively ensuring the safety and stability of the protective box. Through the linkage control of the smoke sensor and the extrusion opening and closing component, the delivery component and the swing component, the intelligent fire extinguishing operation is realized. When fire smoke is detected, the relevant mechanism can be quickly started to extinguish the fire, which improves the efficiency and accuracy of fire extinguishing. BRIEF DESCRIPTION OF THE DRAWINGS

The purpose of the driving mechanism is that the fourth groove 31 is provided in the protection box body 1, and two third limit rods 32 are fixedly connected in the fourth groove 31, and the circumferential surfaces of the two third limit rods 32 are slidably connected with a reciprocating plate 34, and a first slide groove 36 is provided in the reciprocating plate 34, and a first slider 35 is slidably connected in the first slide groove 36, and a rotating rod 37 is rotatably connected in the fourth groove 31, and the first slider 35 is fixedly connected to the side end of the rotating rod 37, and a first driving motor 38 is fixedly connected to the bottom end of the protection box body 1, and the first driving motor 38 is connected to the rotating rod 37 through a coupling, and two push plates 26 are respectively fixedly connected to the two ends of the reciprocating plate 34;By starting the first driving motor 38 to drive the rotating rod 37 to rotate, the rotating rod 37 drives the first slider 35 to perform circular motion. While the first slider 35 performs circular motion, it slides back and forth in the first slide groove 36. Since the position of the first slider 35 is limited by the first slide groove 36, the circular motion of the first slider 35 is a change of the horizontal position and the longitudinal position. The horizontal motion of the first slider 35 can be completed by sliding in the first slide groove 36, but the longitudinal motion of the first slider 35 cannot be performed in the first slide groove 36. Since the reciprocating plate 34 is slidably connected to the circumferential surface of the two third limit rods 32, the first slider 35 will drive the reciprocating plate 34 as a whole to perform reciprocating linear motion on the circumferential surface of the two third limit rods 32 when performing longitudinal motion, so as to achieve the purpose of the reciprocating plate 34 driving the two push plates 26 to perform reciprocating linear motion; the upper inner wall of the protective box 1 is fixedly connected with a lighting lamp 5 for lighting; the lighting lamp 5 can provide lighting when repairing and replacing the electric control equipment in the protective box 1, which is convenient for work. ;

The rotating rod 37 rotates, and the rotating rod 37 rotates to drive the first slider 35 to perform a circular motion. The first slider 35 performs a reciprocating slide in the first slide groove 36 while performing a circular motion. Since the first slider 35 is limited by the first slide groove 36, the circular motion of the first slider 35 is a change in the lateral position and the longitudinal position. The lateral motion of the first slider 35 can be completed by sliding in the first slide groove 36, but the longitudinal motion of the first slider 35 cannot be performed in the first slide groove 36. Since the reciprocating plate 34 is slidably connected to the circumferential surface of the two third limit rods 32, the first slider 35 performs a circular motion. When the reciprocating plate 34 is moved longitudinally, it will drive the reciprocating plate 34 as a whole to perform reciprocating linear motion on the circumferential surface of the two third limit rods 32, so as to achieve the purpose of the reciprocating plate 34 driving the two push plates 26 to perform reciprocating linear motion. The push plate 26 performs reciprocating linear motion and drives the connecting plate 29 and the piston 30 to perform linear reciprocating motion in the air bin 28 through the push rod 27. The piston 30 moves to one side in the air bin 28 and extracts the hot air in the protection box 1 through multiple air inlet pipes and the air inlet cylinder 18 and stores it in the air bin 28. When the piston 30 moves to the other side in the air bin 28, it squeezes the hot air stored in the air bin 28 The hot air in the protective box 1 can be discharged through multiple air outlet pipes and air outlet tubes 17 to accelerate the discharge of the hot air to achieve the purpose of heat dissipation; on rainy days or in weather with high sunlight intensity, the hand-screwed screw head 15 can be turned to drive the driving screw 14 to rotate, and the driving screw 14 can drive the L-shaped plate 9 to move, and the L-shaped plate 9 moves outward to drive the stretching plate 10 to stretch the canopy 11 to unfold, so that the canopy 11 can cover the protective box 1 and the outer edge of the protective box 1, which can prevent rainwater from leaking into the protective box 1, and can also prevent sunlight from directly shining on the protective box 1 to cause a high temperature in the protective box 1;

[0052] The box body 1 is provided with a smoke sensor, which is used to drive the extrusion opening and closing component and the delivery component to start; by starting the second drive motor 56 to drive the bidirectional screw rod 49 to rotate, the bidirectional screw rod 49 drives the two threaded plates 48 to move towards each other, and the two threaded plates 48 respectively drive the two limit columns 40 to move towards the direction of approaching, and the two limit columns 40 slide in the limit slide groove 41, and the limit column 40 drives the sealing plate 42 to move upward to open the accommodating groove 43, and at the same time the threaded plate 48 continues to move, and the threaded plate 48 squeezes the two extrusion plates 51 to move towards the direction of approaching, and the two extrusion plates 51 respectively drive the two adjustment blocks 50 to move towards the direction of approaching, and the two adjustment The block 50 drives the two driving rods 54 to move in the direction of approaching each other, and the two driving rods 54 drive the driving plate 62 to move outward, and the driving plate 62 drives the U-shaped frame 57 to move outward, and sends the nozzle 44 out of the accommodating groove 43. By starting the third driving motor to drive the rotating plate 60 to rotate, the rotating plate 60 drives the second slider 65 to perform a circular motion. The second slider 65 slides in the third slide groove 61 during the circular motion, and drives the reciprocating block 59 to move up and down in the seventh groove 58, thereby driving the driving rack 64 to move up and down, and the driving rack 64 drives the driven gear 63 to swing back and forth, thereby driving multiple nozzles 44 to swing and spray carbon dioxide for fire extinguishing.
