Example 1
Taking fig. 1 and 3 as examples, schematic diagrams of a first embodiment of the heat dissipation and dust removal type power distribution cabinet of the present application are shown. The switch board includes its cabinet body 1 body and ventilation unit and dust collector who sets up on it and is used for connecting above-mentioned two in order to realize the coupling assembling of linkage. The driving source of the ventilation assembly and the dust removal assembly is from a motor 2 in the ventilation assembly, the ventilation assembly is driven by the motor 2 to emit heat in the cabinet body 1 through air flow, and the dust removal assembly is further driven to avoid accumulation of impurities through vibration, so that smoothness of the air flow is guaranteed.
The mating process of the ventilation assembly and the dust removal assembly is described in further detail below. In particular, the motor 2 is activated for the purpose of synchronizing the rotation of the spindle 3 and of the impeller 4 connected to its output. The motor 2 is connected with a control component, the control component can be a control switch arranged outside the cabinet body 1, when the control component is needed, the motor 2 can be directly controlled manually to start and stop, or the control component can be a master control of series connection or parallel connection of the motors 2 in a single or a plurality of power distribution cabinets, so that the control component can be controlled manually, and can be controlled by a program only.
After the motor 2 is started, the main shaft 3 drives the impeller 4 to rotate, so that air in the cabinet is pumped out through the through position of the cabinet body 1 and the ventilation assembly, and outside air enters the power distribution cabinet through the wind window 5 formed in the side part of the cabinet body 1, so that heat is transferred from the inside of the power distribution cabinet to the external environment.
In the above process, the spindle 3 drives the impeller 4 to rotate and simultaneously drives the first follower 6 to rotate. In particular, the first follower 6 can distinguish between the movement states during rotation with respect to the second follower 8, wherein in the driving position the first follower 6 presses the second follower 8 away from the spindle 3, and in the removal position the first follower 6 is not in contact with the second follower 8, the elastic member 9 presses the second follower 8 close to the spindle 3. As the first follower 6 continues to rotate, its position is correspondingly changed between a driving position and a removal position, thereby driving the second follower 8 to slide back and forth in the chute 7 correspondingly, and the resilient member 9 acting as a return correspondingly changes the state of compression and recovery. With reference to fig. 3, the first follower 6 may be a roller, or may be another shape capable of driving the second follower 8 away from or toward each other by a change in rotational orientation, such as a cam.
The rotation of the first follower 6 drives the second follower 8 to slide back and forth in the chute 7, on the one hand, and on the other hand, the dust removal assembly moves back and forth in the vertical direction. Specifically, as the second follower 8 slides, the connecting string 10 having one end fixed thereto moves accordingly. Referring to fig. 3, a portion of the connecting rope 10 is disposed in the chute 7, and slides in the chute 7 along with the second follower 8; and a part extends into the cabinet body 1 and hangs the filter screen 11 at a position on the cabinet body 1 corresponding to the wind window 5, the part drives the filter screen 11 to move up and down in the horizontal direction under the driving of the second driven piece 8, and when the ventilation assembly is matched to realize air flow, the filter screen 11 can be prevented from being attached with greasy dirt, dust and the like in the external environment to obstruct the air flow.
As an implementation manner, the wind windows 5 may be disposed on two sides of the cabinet body 1, and the wind windows 5 may be disposed on one side of the cabinet door of the power distribution cabinet under the condition that the space is enough and the operation of other components or electrical equipment in the cabinet is not affected. The heat dissipation effect is enhanced by increasing the heat dissipation air duct to improve the efficiency of air convection in the cabinet.
As an implementation manner, an air duct 12 is disposed at the top of the cabinet body 1, and the air duct 12 is used for covering the ventilation assembly. The air duct 12 protects the ventilation assembly from foreign objects falling from the through position of the ventilation assembly and the cabinet body 1, and in addition, in order to ensure smoothness of the air duct, referring to fig. 1, the air duct 12 may have a mesh structure at one end, or may be integrally in a mesh structure.
As an implementation manner, a limiting groove 13 is formed in the sliding groove 7 along the sliding direction of the second driven member 8, a limiting block 14 is formed in the second driven member 8, and the limiting block 14 is arranged in the limiting groove 13.
In the process that the second driven member 8 is driven by the first driven member 6, the cooperation of the limiting groove 13 and the limiting block 14 ensures that the second driven member 8 slides in the sliding groove 7 more stably, and the shake between the second driven member 8 and the elastic member 9 in the process of mutual extrusion and resetting is reduced.
As an implementation, the louver 15 is detachably disposed on the louver 5. Through the arrangement of the shutter 15 and the adjustment of the angle thereof, the normal operation of the electric equipment in the power distribution cabinet is prevented from being influenced by the entering of some larger impurities or rainwater while the smoothness of air is ensured.
As an implementation manner, the connecting assembly comprises a sliding rod 16 arranged in the sliding groove 7, one end of the sliding rod 16 is fixed on the inner wall of the cabinet body 1, and the second driven piece 8 is slidably sleeved on the sliding rod 16.
Specifically, when the first follower 6 is in the removal position, the second follower 8 is restored to a position before being pressed away by the first follower 6 along the slide rod 16 by the elastic action of the elastic member 9 in the slide groove 7, and when the first follower 6 is in the driving position, the second follower 8 slides along the slide rod 16 in the slide groove 7 and reversely presses the elastic member 9. By the arrangement of the slide rod 16, the sliding of the second follower 8 in the slide groove 7 is more stable.
As an implementation manner, the elastic member 9 is a spring, the spring is uniformly wound on the sliding rod 16, and compared with the case that the sliding rod 16 and the spring are separately arranged, the spring is wound on the sliding rod 16, so that the matching of the sliding rod 16 and the spring is more stable, and correspondingly, the sliding of the second driven member 8 is also more stable.
Embodiment two:
