All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, 2 and 3, the present embodiment provides a harmonic compensation device with efficient ventilation, which includes a power distribution cabinet housing 1, an air inlet 2 is provided on one side of the power distribution cabinet housing 1, an air outlet 3 is provided on the other side of the power distribution cabinet housing 1, and a fan 5 is provided at the air inlet 2. The external drive drives the fan 5 to rotate, so that the air inlet 2 is in a negative pressure state, suction is generated to the outside, external air flows and enters the power distribution cabinet shell 1, hot air in the power distribution cabinet shell 1 is driven to flow, and the hot air flows outwards from the air outlet 3, so that the hot air in the power distribution cabinet shell 1 is continuously exchanged, and the effect of ventilation and cooling of the power distribution cabinet is realized.
Referring to fig. 1, to increase the range of air flowing in the power distribution cabinet, more heat is carried away as much as possible and faster passes through the inside of the power distribution cabinet housing 1. The inlet is located the lower half of switch board casing 1, and air outlet 3 is located the upper half of switch board.
Referring to fig. 1 and 3, in the process of heat exchanging between hot air in the power distribution cabinet housing 1 and external air through the air inlet 2 and the air outlet 3, impurities (such as dead leaves or small granular impurities) in the external environment may enter the power distribution cabinet housing 1 along with the flow of air. To solve the technical problems. The air inlet 2 is provided with a filter circular plate 4, and the filter circular plate 4 is provided with a filter hole 41. Through setting up filtering plectane 4 in the air flow's way, when some debris or dust that the air carried pass through filtering plectane 4, will be blocked by filtering plectane 4 to avoid debris entering switch board casing 1 inside, influence the normal work of the interior equipment of switch board casing 1.
After the filter circular plate 4 blocks dust or sundries for a long time, the surface of the filter circular plate 4 is gradually covered by some sundries, and further the filter holes 41 through which air passes are covered, so that the flowing flow of the air is gradually reduced, and the heat in the power distribution cabinet shell 1 is difficult to dissipate in time.
Please refer to fig. 3, 4 and 5, in order to solve the above-mentioned technical problems. The filter circular plate 4 outside is provided with and walks around filter circular plate 4 central axis pivoted and scrapes strip 6, scrapes strip 6 on fixed mounting have the brush hair 61 that is used for the clearance filter circular plate 4, and the one end that scrapes strip 6 and is close to filter circular plate 4 center fixed mounting has axostylus axostyle 43, has offered the through-hole that is used for axostylus axostyle 43 to pass on the filter circular plate 4, and the one end that the strip 6 was scraped in axostylus axostyle 43 is kept away from is provided with driving motor.
The equipment in the switch board begins to work, and driving motor drives axostylus axostyle 43 and rotates together for scrape strip 6 on the filter plectane 4 drives brush hair 61 and walks around the rotation of filter plectane 4 central axis, thereby clear up debris or dead leaf etc. that filter plectane 4 surface covered, avoid debris to block up filter plectane 4, reduce the air flow, thereby make the condition that the air can't in time scatter in the switch board casing 1.
In the process of cleaning the filter circular plate 4, the brush hair 61 sweeps through the filter hole 41 in the filter circular plate 4 and dredges the filter hole 41, but the filter circular plate 4 is generally arranged at the air inlet, so that when dust in the filter hole 41 is cleaned, the dust easily enters the power distribution cabinet along with wind, a large amount of dust is attached to the electronic component, and heat dissipation of the electronic component is easily affected.
Please refer to fig. 3, 4 and 5, in order to solve the above-mentioned technical problems. The filter holes 41 are formed in a plurality of groups, the filter holes are circumferentially distributed around the axis of the filter circular plate 4, a plurality of moving plates 7 corresponding to each group of filter holes 41 are arranged on the inner side of the filter circular plate 4, a plurality of push nails 71 for inserting the filter holes 41 are fixedly arranged on the side faces of the moving plates 7, guide posts 72 for guiding the moving plates 7 to move are arranged on the moving plates 7, springs 73 are fixedly arranged between the moving plates 7 and the filter circular plate 4, arc-shaped protruding blocks 74 are arranged in the middle of one side, far away from the filter plates, of the moving plates 7, arc-shaped frames 8 are fixedly arranged on the side faces of the shaft rods 43, and arc-shaped pressing blocks 81 for pushing the arc-shaped protruding blocks 74 to move towards the filter circular plate 4 are fixedly arranged on one side, close to the filter circular plate 4, of the arc-shaped frames 8.
In the rotation process of the shaft lever 43, the scraping strip 6 and the brush hair 61 are driven to clearly remove foreign matters on the surface of the filter circular plate 4, and meanwhile, the arc frame 8 is driven to rotate, so that the arc pressing block 81 on the arc frame 8 is contacted with the arc convex block 74 in the rotation process, and along with the continued rotation of the arc pressing block 81, the arc pressing block 81 pushes the arc convex block 74 to move towards the filter circular plate 4, so that the moving plate 7 is driven to move towards the filter circular plate 4, the push nail 71 on the moving plate 7 is inserted into the filter hole 41, and therefore dust in the filter hole 41 is dredged and cleaned to the outer side of the filter circular plate 4, and when the scraping strip 6 drives the brush hair 61 to sweep, the dust in the filter hole is cleaned timely, so that the effect of dredging and cleaning the dust outside the filter hole is achieved;
meanwhile, the moving plate 7 compresses the spring 73 when moving towards the direction of the filter circular plate 4, after the arc-shaped pressing block 81 bypasses the arc-shaped protruding block 74, the moving plate 7 drives the push pins 71 to be pulled away from the filter holes 41 under the elastic force of the spring 73, and when the arc-shaped pressing block 81 rotates to the arc-shaped protruding block 74 again and contacts with the arc-shaped protruding block 74, the operation is repeated.
Referring to fig. 3, 4 and 5, the filter holes 41 are formed in plural groups and have a plurality of moving plates 7 corresponding thereto, and the arc pressing blocks 81 for pushing the arc protrusions 74 are formed in one group, and the arc pressing blocks 81 contact only one arc protrusion 74 at a time. Thereby reach when carrying out dust clearance to the multiunit filtration pore 41 on the filtration plectane 4, multiunit filtration pore 41 clear up one by one in proper order, avoid appearing all filtration pore 41 and block up the back entirely, outside air has transient flow obstacle, influences the condition that the switch board can interior radiating efficiency, and through clear up one by one in proper order, ensure that the air is in circulation state all the time in the switch board casing 1 to reach stable radiating effect.
Referring to fig. 3, ash guiding grooves 42 are formed between two adjacent groups of filter holes 41 on the outer side of the filter circular plate 4, and one end of each ash guiding groove 42 near the center of the filter circular plate 4 is communicated.
When the scraper blade rotates around the central line of the filter circular plate 4, the brush hair 61 on the scraper blade moves to the ash guiding groove 42 after cleaning dust on the surface of the filter circular plate 4, and the ash guiding groove 42 is concave, so that the dust on the brush hair 61 shakes at the ash guiding groove 42, and the dust on the brush hair 61 falls into the ash guiding groove 42, thereby cleaning the dust attached to the brush hair 61, avoiding the brush hair 61 from adhering excessive dust, and coating the filter circular plate 4 again.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
