[0023] The present invention has the following beneficial effects:

[0024] The present invention provides a heat dissipation component inside the explosion-proof control cabinet. The heat dissipation component is started to perform heat dissipation treatment on the explosion-proof control cabinet, so that the heat generated by the electrical components can be dissipated in time. The dust-proof component can protect the explosion-proof control cabinet to prevent dust from entering the interior of the explosion-proof control cabinet and accumulating on the surface of the electrical components, resulting in the heat generated by the electrical components cannot be discharged in time. An isolation component is provided on the surface of the explosion-proof control cabinet. The isolation component and the sealing component cooperate with each other to seal the explosion-proof control cabinet. When explosion and combustion occur inside the explosion-proof control cabinet, the explosion-proof control cabinet can be sealed in time to prevent the flow of gas from causing the fire to become larger and larger.

[0025] The starting motor of the present invention drives the rotating rod to rotate, and the rotating rod drives the exhaust fan to rotate above the interior of the explosion-proof control cabinet when rotating. The air pressure generated by the exhaust fan when rotating will flow downward, and will be mixed with the heat generated by the electrical components during the flow process. As the exhaust fan continues to rotate, the gas inside the explosion-proof control cabinet will be discharged through the dustproof frame, thereby performing heat dissipation treatment on the interior of the explosion-proof control cabinet.

[0026] The rotating rod of the present invention drives the circular groove frame to rotate through the driving frame when rotating, and the circular groove frame pushes the extrusion rod to extrude the contact rod when rotating. At this time, the contact rod pushes the sliding block to slide inside the sliding hole through pressure, and the sliding block pushes the scraper to move upward through the connecting plate when moving. The scraper cleans the surface of the dustproof frame when moving to prevent dust from accumulating on the surface of the dustproof frame and affecting the heat dissipation effect. The scraper slides on the surface of the positioning frame through the sliding groove, thereby improving the stability of the scraper when moving.

[0027] When the electric push rod of the present invention moves upward, it pushes the bent plate upward through the lifting frame, and at the same time, the lifting frame pushes the two inclined plates to move in the merging direction through the pulling plate. When moving, the inclined plate pushes the moving frame to slide on the surface of the limit plate, and pushes the bent plate to tilt upward during movement, so that the bent plate can drive the isolation frame to separate from the surface of the explosion-proof control cabinet, so as to centrally process the dust inside the isolation frame. When the electric push rod moves downward, it pushes the isolation frame to squeeze the surface of the explosion-proof control cabinet. When explosion and combustion occur inside the explosion-proof control cabinet, the isolation frame will play an isolation role to prevent the electrical components inside the explosion-proof control cabinet from being ejected and causing greater damage.

[0028] When the present invention starts the motor to reverse, the sliding block moves with the rotation of the motor and pushes the bending plate to move downward. When the bending plate moves downward, the sealing plate is pushed downward by the synchronous plate. After the sealing plate contacts the bottom of the inner wall of the isolation frame, the air hole is sealed. When combustion occurs inside the explosion-proof control cabinet, the air hole is sealed to avoid the flow of air, thereby gradually reducing the intensity of the combustion.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

An isolation component 6 is provided on the surface of the explosion-proof control cabinet 1. The isolation component 6 and the sealing component 7 cooperate with each other to seal the explosion-proof control cabinet 1. When explosion and combustion occur inside the explosion-proof control cabinet 1, the explosion-proof control cabinet 1 can be sealed in time to prevent the flow of gas from causing the fire to become larger and larger.

[0047] The heat dissipation component 4 includes a fixing hole 13, which is opened on the surface of the explosion-proof control cabinet 1, and a dustproof frame 14 is fixedly connected to the inner wall of the fixing hole 13.

When the rotating rod 17 of the present invention rotates, the circular groove frame 30 is driven to rotate by the driving frame 20. When the circular groove frame 30 rotates, it pushes the extrusion rod 29 to squeeze the contact rod 21. At this time, the contact rod 21 will push the sliding block 22 to slide inside the sliding hole 12 through pressure. When the sliding block 22 moves, it pushes the scraper 24 to move upward through the connecting plate 26. When the scraper 24 moves, it cleans the surface of the dustproof frame 14 to prevent dust from accumulating on the surface of the dustproof frame 14 and affecting the heat dissipation effect. The scraper 24 slides on the surface of the positioning frame 25 through the slide groove 23, thereby improving the stability of the scraper 24 when moving. The end of the scraper 24 away from the positioning frame 25 contacts the surface of the dustproof frame 14, and the end of the sliding block 22 extends to the outer end of the explosion-proof control cabinet 1, and the contact rod 21 is located inside the explosion-proof control cabinet 1.

At the same time, the lifting frame 41 will push the two inclined plates 43 to move in the merging direction through the pull plate 42. When moving, the inclined plate 43 pushes the moving frame 45 to slide on the surface of the limit plate 44, and pushes the bent plate 46 to tilt upward during movement so that the bent plate 46 can drive the isolation frame 48 to separate from the surface of the explosion-proof control cabinet 1, so as to centrally process the dust inside the isolation frame 48. When the electric push rod 40 moves downward, it pushes the isolation frame 48 to squeeze the surface of the explosion-proof control cabinet 1. When explosion and combustion occur inside the explosion-proof control cabinet 1, the isolation frame 48 will play an isolation role to prevent the electrical components inside the explosion-proof control cabinet 1 from being ejected and causing greater damage. The bottom of the electric push rod 40 is fixedly connected to the top of the motor housing 10.

When the bending plate 57 moves downward, the sealing plate 54 is pushed downward by the synchronous plate 50. After the sealing plate 54 contacts the bottom of the inner wall of the isolation frame 48, the air hole 49 is sealed.

The rotating rod 17 is driven to rotate. When the rotating rod 17 rotates, the exhaust fan 16 is driven to rotate above the interior of the explosion-proof control cabinet 1. The air pressure generated when the exhaust fan 16 rotates will flow downward, and in the process of flowing, it will be mixed with the heat generated by the electrical components. As the exhaust fan 16 continues to rotate, the gas inside the explosion-proof control cabinet 1 will be discharged through the dustproof frame 14, thereby performing heat dissipation treatment on the interior of the explosion-proof control cabinet 1. When the rotating rod 17 rotates, it drives the circular groove frame 30 to rotate through the driving frame 20. When the circular groove frame 30 rotates, it pushes the extrusion rod 29 to squeeze the contact rod 21. At this time, the contact rod 21 will push the sliding block 22 to slide inside the sliding hole 12 through pressure. When the sliding block 22 moves, it pushes the scraper 24 through the connecting plate 26. When the electric push rod 40 moves upward, the scraper 24 cleans the surface of the dust frame 14 to prevent dust from accumulating on the surface of the dust frame 14 and affecting the heat dissipation effect.

The inclined plate 43 pushes the moving frame 45 to slide on the surface of the limit plate 44 when moving, and pushes the bent plate 46 to tilt upward when moving, so that the bent plate 46 can drive the isolation frame 48 to separate from the surface of the explosion-proof control cabinet 1, so as to centrally process the dust inside the isolation frame 48. When the rod 40 moves downward, it pushes the isolation frame 48 to squeeze the surface of the explosion-proof control cabinet 1. When explosion and combustion occur inside the explosion-proof control cabinet 1, the isolation frame 48 will play an isolating role to prevent the electrical components inside the explosion-proof control cabinet 1 from being ejected and causing greater damage. When the motor 11 is started to reverse, the sliding block 22 will move with the rotation of the motor 11 and push the bending plate 57 to move downward. When the bending plate 57 moves downward, it pushes the sealing plate 54 to move downward through the synchronous plate 50. The sealing plate 54 contacts the bottom of the inner wall of the isolation frame 48 and seals the air hole 49. When combustion occurs inside the explosion-proof control cabinet 1, sealing the air hole 49 can prevent the flow of air, thereby gradually reducing the intensity of the burning fire.
