[0001] One or more embodiments of the present specification relate to the field of electrical control technology, and in particular to an electrical control box that can be placed outdoors. Background Art

[0002] An electrical control box contains one or more switchgear and related control, measurement, signal, protection, regulation and other equipment. The equipment in the electrical control box requires a reasonable temperature environment for operation, and a heat sink needs to be installed to dissipate heat.

[0003] Existing electrical control boxes dissipate heat by opening ventilation holes on the box body, and dust filters are installed in the ventilation holes. However, the inventors found that the outside air contains a large amount of dust and other impurities, which causes a large amount of difficult-to-clean dust and impurities to adhere to the dust filter. The accumulation of dust and impurities over a long period of time will block the ventilation holes and affect the heat dissipation effect. Summary of the Invention

[0004] In view of this, the purpose of one or more embodiments of this specification is to provide an electrical control box that can be placed outdoors to prevent dust and impurities from accumulating for a long time and blocking the ventilation holes, thereby affecting the heat dissipation effect.

[0029] Based on the above objectives, one or more embodiments of this specification provide an electrical control box that can be placed outdoors, characterized by including:

[0030] The control box 1 has a ventilation hole 2 at the top of the left and right side walls respectively;

[0031] There are two dust filters 3, one at the outer end of each ventilation hole 2. The top of the dust filter 3 is clamped by a fixing clip 4, and the other end of the fixing clip 4 is fixed with a connecting block 5;

[0032] There are two knocking shafts 6, each of which is rotatably provided with a knocking shaft 6 on the upper side wall of the ventilation hole 2 inside the dust filter 3. The top end of the knocking shaft 6 is rotatably provided on the upper side wall of the ventilation hole 2. A knocking disk 7 is rotatably provided on the knocking shaft 6. A rope drum 8 is fixed on the knocking shaft 6 on the lower side of the knocking disk 7. A rotating rope 9 is wound on the rope drum 8. A receiving plate 10 is fixed on the top wall of the ventilation hole 2 next to the top end of the knocking shaft 6. The knocking shaft 6 is elastically connected to the receiving plate 10 through a clockwork spring 11;

[0033] The swing shaft 12 is movable and passes through the top wall of the control box 1. Two longitudinal first wind shields 13 are fixed on both sides of the swing shaft 12 outside the control box 1. The two first wind shields 13 are in the same plane. The side of the swing shaft 12 is also fixed with a longitudinal second wind shield 14. The second wind shield 14 is perpendicular to the first wind shield 13. The bottom end of the swing shaft 12 is slidably sleeved with a pulling cylinder 15. Two pull rings 16 are fixed on both sides of the pulling cylinder 15. Each pull ring 16 is connected to a pulling rope 17. The other end of the pulling rope 17 is connected to the connecting block 5 on the same side, and the other end of the rotating rope 9 is connected to the pull ring 16 on the same side.

[0034] The present invention provides an electrical control box that can be placed outdoors. The dust filter 3 is arranged in the ventilation hole 2 by opening a ventilation hole 2 on the opposite side wall of the control box body 1. The top of the dust filter 3 is connected to the connecting block 5 by a fixing clip 4. When there is wind outdoors, the first wind shield 13 is blown to make the swing shaft 12 swing. The pulling cylinder 15 at the bottom end of the swing shaft 12 swings and pulls the pulling rope 17 and the rotating rope 9 back and forth. Under the back and forth pulling of the pulling rope 17, the dust filter 3 is straightened and vibrated many times, so that the attached dust and impurities fall off. The rotating rope 9 makes the knocking shaft 6 rotate and drives the knocking plate 7 to rotate. The offset knocking plate 7 rotates and continuously knocks the dust filter 3 on the side, so that the attached dust is fully shaken off, effectively achieving cleaning, preventing the accumulation of dust and impurities, and effectively ensuring the heat dissipation effect.

[0035] Among them, when the wind direction changes or the wind direction is not facing the first wind shield 13, the wind blows towards the second wind shield 14. The single-piece second wind shield 14 is forced to drive the swing shaft 12 to rotate, driving the first wind shield 13 to rotate to face the wind direction, effectively adjusting the direction of the first wind shield 13 according to the wind direction.

[0036] As an optional embodiment, the lower side wall of the ventilation hole 2 is inclined toward the outside of the control box body 1, and a funnel-shaped dust exhaust hole 18 is opened on the lower side wall of the ventilation hole 2 inside the dust filter 3. A dust exhaust channel 19 is opened at the lower end of the dust exhaust hole 18. The dust exhaust channel 19 is inclined toward the outside of the control box body 1, and the other end of the dust exhaust channel 19 is connected to the outside of the control box body 1.

[0037] The inclined lower side wall of the ventilation hole 2 prevents the dust and impurities that are shaken off from sliding into the control box 1.

[0038] As an optional embodiment, a through hole 20 is opened on the top wall of the ventilation hole 2 on the upper side of the dust filter 3. The top end of the through hole 20 is arc-shaped and bent toward the inner side of the control box body 1. One end of the arc-shaped through hole 20 is connected to a narrowed positioning hole 21. The other end of the positioning hole 21 is connected to the control box body 1 through a movable hole 22. The positioning hole 21 is movably provided with a fixing clip 4, and the connecting block 5 is movably provided in the movable hole 22.

[0039] The connecting block 5 pulls the dust filter 3 through the fixing clamp 4 , and the pulling rope 17 causes the connecting block 5 to move back and forth in the movable hole 22 to continuously straighten or relax the dust filter 3 .

[0040] Specifically, the width of the movable block is greater than the width of the locking hole 21 .

[0041] The width of the movable block is greater than the width of the locking hole 21 to prevent the movable block from retracting into the ventilation hole 2 when the dust filter 3 becomes loose.

[0042] As an optional embodiment, a plurality of hemispherical striking blocks 23 are fixed to the edge of the striking plate 7 .

[0043] The hemispherical knocking block 23 enables the knocking plate 7 to continuously vibrate the dust filter 3 and increase the frequency of vibration when knocking the dust filter 3, so that dust and impurities fall off quickly.

[0044] As an optional embodiment, protective discs are fixed to both ends of the rope drum 8 , and the diameter of the protective discs is larger than the outer diameter of the rope drum 8 .

[0045] As an optional embodiment, a plurality of wiring tubes 24 are provided on the inner side wall of the control box 1 .

[0046] As an optional implementation, the width of the swing shaft 12 is smaller than the inner diameter of the swing hole 25 .

[0047] Specifically, a swing hole 25 is opened in the center of the top wall of the control box body 1, and an annular rolling groove 26 is extended from the side of the swing hole 25 to the top wall of the control box body 1 on the horizontal circumferential side. Correspondingly, two horizontal support rods 27 are symmetrically fixed on the side of the swing shaft 12, and the two support rods 27 are located on the same straight line. The ends of both ends of each support rod 27 are rotatably provided with rotating wheels 28, and the rotating wheels 28 are rotatably set in the rolling groove 26.

[0048] Furthermore, the bottom end of the swing shaft 12 is connected to a counterweight rope 29 , and the bottom end of the counterweight rope 29 is connected to a counterweight block 30 .

[0049] The rotating wheel 28 rotates in the rolling groove 26, thereby driving the swing shaft 12 to rotate according to the wind direction. The counterweight block 30 pulls the bottom end of the swing shaft 12 through the counterweight rope 29, so that the swing shaft 12 can maintain vertical balance when there is no wind, and is always ready to receive the wind. When the swing shaft 12 swings, the counterweight block 30 also swings accordingly. When the wind weakens or disappears, the counterweight block 30 continues to swing, thereby driving the swing shaft 12 to continue swinging, achieving a good force storage effect.
