Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, specifically a leak-proof outdoor power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Currently, some outdoor power distribution cabinets are equipped with ventilation openings to improve their heat dissipation. However, this results in poor protection performance in rainy weather. During rainy weather, rainwater can easily enter the power distribution cabinet through the ventilation openings. In addition, when rainy weather comes, the humidity in the air increases, and a large amount of moisture enters the power distribution cabinet, which can easily damage the internal parts.

By setting a shielding mechanism 5, when the cabinet 1 needs ventilation, the baffle 502 can be adjusted to remove the sealing plug 505 from the ventilation shell 3, thus releasing the seal on the ventilation shell 3. Subsequently, the cabinet 1 can dissipate heat through the ventilation shell 3. When encountering rainy weather or high humidity, the baffle 502 can be adjusted to allow the sealing plug 505 to enter the ventilation shell 3, sealing the ventilation shell 3. This can block external moisture and prevent moisture from entering the cabinet 1, improving the safety of the cabinet 1.

[0018] Reference Figure 2 and Figure 3 One end of the screw 510 is rotatably connected to the inner wall of the adjusting seat 501 via a bearing. The threads on the surfaces of the two screws 510 are opposite. The adjusting block 504 is trapezoidal in shape. One side of the pressure roller 512 contacts the surface of the adjusting block 504. By setting the bearing, one end of the screw 510 can be supported, improving the stability of the screw 510 and facilitating the rotation of the screw 510. By setting the opposite threads, the two screw sleeves 511 can be adjusted to move closer or further apart. By setting the adjusting block 504, the pressure roller 512 can be adjusted to adjust the push plate 503. Reference Figure 4 and Figure 5The anti-blocking mechanism 6 includes a fixed box 601. One side of the fixed box 601 is fixedly connected to the inner wall of the cabinet 1. A pressure block 602 is provided on the top of the fixed box 601. A flipping frame 603 is provided on the surface of the pressure block 602. The front and rear sides of the flipping frame 603 are rotatably connected to the mounting block 604 via a pivot. One side of the mounting block 604 is fixedly connected to the inner wall of the cabinet 1. Five striking blocks 605 are fixedly connected to the top of one side of the flipping frame 603. One side of the striking block 605 extends into the inner cavity of the ventilation shell 3. By setting the pressure block 602, it can be used to squeeze the flipping frame 603, which facilitates the adjustment of the flipping frame 603. By setting the mounting block 604 and the pivot, it is easy to adjust the flipping frame 603. By setting the striking block 605, it can be used to knock the filter plate 4 and shake off the dust on the surface of the filter plate 4. Reference Figure 4 and Figure 5 A second motor 606 is fixedly connected to one side of the fixed box 601. The output end of the second motor 606 passes through the inner cavity of the fixed box 601 and is fixedly fitted with a cam 607. A lifting plate 608 is provided on the top of the cam 607. A second spring 609 is fixedly connected between the top of the lifting plate 608 and the inner wall of the fixed box 601. Lifting rods 610 are fixedly connected to both sides of the bottom of the pressure block 602. The bottom of the lifting rods 610 passes through the fixed box 601 and is fixedly connected to the lifting plate 608. A third spring 611 is fixedly connected to the surface of the flipping frame 603. A positioning frame 612 is fixedly connected to one end of the third spring 611. One side of the positioning frame 612 is fixedly connected to the inner wall of the cabinet 1. By setting the cam 607, the lifting plate 608 can be adjusted. By setting the second spring 609, the lifting plate 608 can be moved downward to reset. By setting the third spring 611, the flipping frame 603 can be reset. By setting the positioning frame 612, one end of the third spring 611 can be fixed.

[0019] Working Principle: When encountering rainy weather or excessive external humidity, the first motor 509 can be controlled to drive the screw 510 to rotate. The rotation of the screw 510, through the cooperation of the screw sleeve 511, can drive the two pressure rollers 512 to move towards the center, gradually releasing the pressure on the adjusting block 504. At this time, the first spring 508 resets, and through the cooperation of the pressure plate 507, it can drive the two push plates 503 to move towards the center. The push plates 503, through the cooperation of the moving frame 506, can drive the two baffles 502 to move towards the center until the baffles 502 are released from the ventilation shell 3. The sealing plug 505 will also enter the ventilation shell 3. The ventilation shell 3 can be sealed by the baffles 502 and the sealing plug 505, which can block external humidity and prevent excessive external humidity from affecting the internal equipment of the cabinet 1. When heat dissipation is required through the ventilation shell 3, the first motor 509 can be controlled to drive the screw 510 to reverse. The reverse rotation of the screw 510, through the cooperation of the screw sleeve 511... The combined action can move the pressure roller 512 to press the adjusting block 504. With the cooperation of the adjusting block 504, the two push plates 503 can be moved away from each other. With the cooperation of the moving frame 506, the push plate 503 can move the baffle 502 away from the ventilation shell 3. The baffle 502 moves the sealing plug 505 out of the ventilation shell 3, releasing the seal on the ventilation shell 3. At this time, the cabinet 1 can dissipate heat through the ventilation shell 3. During ventilation, in order to prevent the filter plate 4 from being blocked, the second motor 606 can be turned on. The second motor 606 can turn the cam 607. The rotation of the cam 607 can drive the pressure block 602 to move up and down repeatedly through the cooperation of the lifting plate 608 and the lifting rod 610. The movement of the pressure block 602 can drive the flipping frame 603 to flip left and right repeatedly through the cooperation of the third spring 611. The flipping frame 603 can drive the striking block 605 to continuously strike the filter plate 4, which can shake off the dust on the surface of the filter plate 4, prevent the filter plate 4 from being blocked, and improve the heat dissipation effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
