[0018] The present invention provides an automatic temperature control dust removal device for a PLC control cabinet. It has the following beneficial effects:

[0019] 1. The automatic temperature-controlled dust removal device of the PLC control cabinet drives the connecting rod to rotate during the rotation of the air intake fan. The connecting rod rotates with two sweeping groove scrapers through the fixed rotating frame to scrape off the dust isolated on the surface of the elastic dustproof net, allowing the dust to pass through the groove inside the sweeping groove scraper, and be driven to rotate by the sweeping groove scraper. Under the action of centrifugal force, the dust is thrown into the dust accumulation groove. The dust falling into the dust accumulation groove overcomes the suction force between the two upper magnetic blocks and the lower magnetic blocks by pulling down the magnetic cover door, and the magnetic cover door is opened to process the dust, so as to process the dust on the surface of the elastic dustproof net to prevent excessive dust accumulation from affecting the heat dissipation effect of the PLC control cabinet.

[0020] 2. When the automatic temperature control dust removal device of the PLC control cabinet rotates through the connecting rod, the first inclined block cooperates with the first inclined block to push the pulling spring outward, and the two pulling magnetic blocks and the matching magnetic blocks attract each other to pull the elastic dustproof net to the right. When it is pulled to a certain limit, the two sweeping groove scrapers of the elastic dustproof net will be used to shake off the dust, and then it will be rotated again to repeatedly pull the elastic dustproof net, and continuously let the elastic dustproof net shake out the internal dust to the left to prevent dust from accumulating on the elastic dustproof net, thereby preventing the influence of dust on heat dissipation.

[0021] 3. The automatic temperature-controlled dust removal device of the PLC control cabinet allows the dust on the elastic dust-proof net to move to the left under the action of inertia, and the sweeping groove scraper rotates, which allows the sweeping groove scraper to collect the ejected dust and throw it into the dust storage groove, so that the sweeping groove scraper can more easily scrape the dust on the elastic dust-proof net, thereby improving the dust cleaning effect and the heat dissipation effect.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Embodiment 1

[0034] See also Figure 1-7 The present invention provides a technical solution: an automatic temperature control dust removal device for a PLC control cabinet, comprising a PLC control cabinet 1, an air inlet 2 fixedly connected to the left side of the PLC control cabinet 1, an air outlet 3 fixedly connected to the right side of the PLC control cabinet 1, an air inlet fan 5 fixedly connected inside the air inlet 2, an air outlet fan 4 fixedly connected inside the air outlet 3, a dust prevention mechanism 7 fixedly connected inside the air inlet 2, an impact mechanism 8 movably connected to the outer wall of the dust prevention mechanism 7, a temperature control device 6 fixedly connected inside the PLC control cabinet 1, the temperature control device 6 detects the temperature inside the PLC control cabinet 1, and adjusts the rotation speeds of the air inlet fan 5 and the air outlet fan 4 according to the temperature inside. When the temperature is high, the rotation speeds of the air inlet fan 5 and the air outlet fan 4 are accelerated to increase the circulating airflow so that the inside of the PLC control cabinet 1 can quickly dissipate heat. When the temperature inside the PLC control cabinet 1 is low, the rotation speeds of the air inlet fan 5 and the air outlet fan 4 are slowed down to reduce energy loss.

[0035] The dust-proof mechanism 7 comprises:

[0036] An elastic dustproof net 701, which is fixedly connected to the inside of the air inlet 2. The elastic dustproof net 701 is elastic and can be deformed by being pulled, and has the ability to restore its shape;

[0037] A connecting rod 702, the connecting rod 702 is fixedly connected to the right side of the air inlet fan 5 and the left side of the elastic dustproof net 701;

[0038] The fixed rotating frame 703 is fixedly connected to the outer wall of the connecting rod 702 .

[0039] The outer wall of the fixed rotating frame 703 is located on the left side of the elastic dustproof net 701 and is fixedly connected with a sweeping groove scraper 704, and two sweeping groove scrapers 704 are provided. The two sweeping groove scrapers 704 are in contact with the elastic dustproof net 701, and the connecting rod 702 is driven to rotate during the rotation of the air inlet fan 5. The connecting rod 702 rotates with the two sweeping groove scrapers 704 through the fixed rotating frame 703. The sweeping groove scraper 704 will rotate on the surface of the elastic dustproof net 701, scrape off the dust isolated on the surface of the elastic dustproof net 701, and process the dust, so as to process the dust on the surface of the elastic dustproof net 701 and prevent excessive dust accumulation from affecting the heat dissipation effect of the PLC control cabinet 1.

[0040] A dust storage groove 705 is fixedly connected to the bottom of the air inlet 2, and a magnetic cover door 706 is movably connected to the bottom of the dust storage groove 705. Dust passes through the groove inside the sweeping groove scraper 704, is driven to rotate by the sweeping groove scraper 704, and is thrown into the dust storage groove 705 under the action of centrifugal force.

[0041] The outer wall of the magnetic cover door 706 is fixedly connected to two lower magnetic blocks 708, and the outer wall of the dust storage tank 705 is fixedly connected to two upper magnetic blocks 707 corresponding to the two lower magnetic blocks 708. The magnetic cover door 706 is pulled down to overcome the suction force between the two upper magnetic blocks 707 and the lower magnetic block 708, and the magnetic cover door 706 is opened to process the dust. After the processing, the magnetic cover door 706 can be directly put back in place, and the magnetic cover door 706 can be fixed to the bottom of the dust storage tank 705 again through the upper magnetic blocks 707 and the corresponding lower magnetic blocks 708.

[0042] When in use, the air inlet fan 5 fills the gas into the PLC control cabinet 1 through the air inlet 2, and the air outlet fan 4 discharges the gas from the inside of the PLC control cabinet 1 through the air outlet 3 to realize the air circulation inside the PLC control cabinet 1 for heat dissipation. The temperature inside the PLC control cabinet 1 is detected by the temperature control device 6, and the rotation speeds of the air inlet fan 5 and the air outlet fan 4 are adjusted according to the internal temperature. When the temperature is high, the rotation speeds of the air inlet fan 5 and the air outlet fan 4 are accelerated to increase the circulating airflow so that the inside of the PLC control cabinet 1 can be quickly cooled. When the temperature inside the PLC control cabinet 1 is low, the rotation speeds of the air inlet fan 5 and the air outlet fan 4 are slowed down to reduce energy loss. When the airflow enters the inside of the PLC control cabinet 1 through the air inlet fan 5, it will pass through the elastic dustproof net 701, so that the elastic dustproof net 701 can intercept dust in the passing air to prevent accumulation inside the PLC control cabinet 1 Dust, during the rotation of the air intake fan 5, the connecting rod 702 is driven to rotate, and the connecting rod 702 rotates with the two sweeping groove scrapers 704 through the fixed rotating frame 703. The sweeping groove scrapers 704 rotate on the surface of the elastic dustproof net 701 to scrape off the dust isolated on the surface of the elastic dustproof net 701, and allow the dust to pass through the groove inside the sweeping groove scraper 704, and be driven to rotate by the sweeping groove scraper 704, and the dust is thrown into the dust accumulation groove 705 under the action of centrifugal force. The dust falling into the dust accumulation groove 705 overcomes the suction force between the two upper magnetic blocks 707 and the lower magnetic block 708 by pulling down the magnetic cover door 706, and the magnetic cover door 706 is opened to process the dust. After the processing, the magnetic cover door 706 can be directly put back to its original position, and the magnetic cover door 706 can be fixed to the bottom of the dust accumulation groove 705 by the upper magnetic block 707 and the corresponding lower magnetic block 708 again.

[0043] Embodiment 2

[0044] See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0045] The impact mechanism 8 includes a movable rod 801, which is movably connected to the inside of the connecting rod 702. The right side of the movable rod 801 is fixedly connected to a pulling spring 802 located inside the connecting rod 702. The right side of the pulling spring 802 is fixedly connected to a connecting head 810, and the right side of the connecting head 810 is movably connected to the inside of the connecting rod 702.

[0046] On the right side of the connecting rod 702, two second inclined blocks 808 are fixedly connected to the outer wall of the pulling spring 802, and the outer wall of the movable rod 801 is fixedly connected to two first inclined blocks 807 corresponding to the second inclined blocks 808. When the connecting rod 702 rotates, the movable rod 801 cannot rotate through the limiting column 805 and the limiting column 809. When the connecting rod 702 rotates, the pulling spring 802 will be pushed outward through the cooperation of the first inclined blocks 807 and the first inclined blocks 807.

[0047] The right side of the movable rod 801 is located on the right side of the elastic dustproof net 701 and is fixedly connected to a connecting frame 803. The right side of the connecting frame 803 is fixedly connected to a limiting column 805. The outer wall of the limiting column 805 is movably connected to a limiting frame 809, and the limiting frame 809 is fixedly connected to the inner wall of the PLC control cabinet 1.

[0048] The outer wall of the elastic dustproof net 701 is fixedly connected with a matching magnetic block 806, and the left side of the connecting frame 803 is located on the right side of the matching magnetic block 806 and is fixedly connected with two pulling magnetic blocks 804. The movable rod 801 pushes the connecting frame 803 outward. When the connecting frame 803 moves outward, the two pulling magnetic blocks 804 and the matching magnetic block 806 attract each other, thereby pulling the elastic dustproof net 701 to the right.

[0049] When in use, when the connecting rod 702 is rotated, the movable rod 801 cannot rotate by the limiting column 805 and the limiting column 809. When the connecting rod 702 rotates, the first inclined block 807 cooperates with the first inclined block 807 to push the pulling spring 802 outward, and at the same time, the connecting frame 803 is pushed outward through the movable rod 801. When the connecting frame 803 moves outward, the two pulling magnetic blocks 804 and the matching magnetic blocks 806 attract each other, and the elastic dustproof net 701 is pulled to the right. When the pulling force exceeds the suction force between the two pulling magnetic blocks 804 and the matching magnetic blocks 806, the elastic dustproof net 701 will rebound under the action of its own elastic force, and then hit the two sweeping groove scrapers 704, so that the elastic dustproof net 701 stops suddenly. The dust on the dust moves to the left under the action of inertia and moves downward under the action of gravity. Under the rotation of the sweeping groove scraper 704, the sweeping groove scraper 704 can collect the ejected dust and throw it into the dust storage groove 705. When the connecting rod 702 continues to rotate, the second inclined block 808 and the first inclined block 807 are no longer in effect, allowing the pulling spring 802 to pull the movable rod 801 to the left, so that the pulling magnetic block 804 on the connecting frame 803 will hit the elastic dustproof net 701, causing the elastic dustproof net 701 to vibrate and shake off the dust. Then rotate again to allow the two pulling magnetic blocks 804 to pull the elastic dustproof net 701 outward again by cooperating with the magnetic block 806, so as to repeatedly pull the elastic dustproof net 701, and continuously allow the elastic dustproof net 701 to shake out the internal dust to the left.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
