Description

A new type of withdrawable power distribution cabinet

Technical field

The utility model relates to the technical field of power distribution equipment, specifically a new type of withdrawable power distribution cabinet.

Background technique

The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. According to different structural types, power distribution cabinets are divided into withdrawable power distribution cabinets and fixed power distribution cabinets. In particular, withdrawable power distribution cabinets have a small footprint and are easy to maintain, and are widely used. At present, when the existing withdrawable power distribution cabinet is in use, the cabinet will be in a suspended state when it is completely pulled out. It does not have a corresponding support structure and has poor stability. Under the action of gravity, it is easy to cause damage to the device and affect the power distribution cabinet. service life.

A Chinese patent discloses a pull-out power distribution cabinet (Authorization Announcement No. CN215732887U). This utility model uses rollers to cooperate with the first chute, and combined with the cooperation of the slide block and the second chute to realize the sliding extraction of the power distribution cabinet. One spring effectively prevents the power distribution cabinet from colliding with the device when it is pulled out and slid in, which improves the buffering effect of the power distribution cabinet. When the power distribution cabinet is pulled out, the piston rod combines the hook and the hook under the action of the second spring. The mutual cooperation of the rings supports the power distribution cabinet and ensures the stability of the device. The heat dissipation holes ensure the heat dissipation effect of the device. However, due to the compact internal structure of the drawer-type power distribution cabinet, the internal heat cannot be completely dissipated by relying on the heat dissipation holes alone, and it is easy for rain or dust to enter the interior due to rainy or sandy days, causing damage to electronic components.

In order to achieve the above purpose, the utility model provides the following technical solution: a new type of withdrawable power distribution cabinet, including a cabinet body, a cabinet door is rotatably connected to one side of the front end of the cabinet body, and symmetrically installed on both sides of the cabinet body. Dust-proof and heat dissipation mechanism, a number of drawers are arranged at equal distances inside the cabinet, roller slide rails are symmetrically fixed on both sides of the drawer, one side of the roller slide rail is fixed to the inside of the cabinet, and the cabinet Two heat dissipation boxes are fixed at the rear end, and fans are fixed inside the heat dissipation boxes.

As a further solution of the present invention: the dust-proof and heat dissipation mechanism includes two worms symmetrically connected to both sides of the cabinet. A number of worm gears are equidistantly arranged on one side of the worm gear, and the interior of the worm gear is connected through There is a rotating shaft, and a baffle is fixed on the outer layer of the rotating shaft.

As a further solution of the present invention: the bottom outer layer of the worm is covered with a pulley, a belt is rotatably connected between the two pulleys, and a motor is fixedly connected to one of the pulleys.

As a further solution of the present invention: slots are provided on both sides of the cabinet at positions corresponding to the baffles, and a dust filter is provided inside the slots.

As a further solution of the present invention: a through hole is provided at the rear end of the cabinet and the rear end of the dustproof net corresponding to the position of the fan, and a dustproof net is fixed inside the through hole.

As a further solution of the present invention: the top end of the worm is inserted and connected with a bearing seat fixed on the top layer inside the cabinet.

Compared with the existing technology, the beneficial effects of the present utility model are: the interior of the utility model is configured as a drawer-type structure, which can slide freely, thereby facilitating the installation of electrical components inside the drawer and the maintenance of the electrical components inside the drawer. It is more convenient because the drawer structure is relatively compact, and the demand for heat dissipation will also increase. The dust-proof heat dissipation mechanism and the fan can effectively dissipate the internal heat, and a large amount of dust will not enter the inside of the cabinet to avoid dust. Too much can cause circuit problems with electronic components.

Detailed ways

Please refer to Figures 1 to 6. In the embodiment of the present utility model, a new type of withdrawable power distribution cabinet includes a cabinet 1. A cabinet door 4 is rotatably connected to one side of the front end of the cabinet 1. The two sides of the cabinet 1 are symmetrically installed. There is a dust-proof heat dissipation mechanism 3. The dust-proof heat dissipation mechanism 3 includes two worms 8 that are symmetrically rotated and connected to both sides of the cabinet 1. The top of the worm 8 is inserted and connected to a bearing seat fixed to the top layer of the cabinet 1. A number of worm gears 9 are arranged equidistantly on one side. The rotation of the worm gear 8 drives the rotation of the worm gear 9. The inside of the worm gear 9 is connected with a rotating shaft 10. The rotation of the worm gear 9 drives the rotating shaft 10 to rotate. A baffle 12 is fixed on the outer layer of the rotating shaft 10, and the rotating shaft 10 rotates. The baffle 12 is driven to swing, so that the opening and closing of the slot can be controlled. There are slots on both sides of the cabinet 1 corresponding to the position of the baffle 12. A dust filter is provided inside the slot, and the outer layer of the bottom of the worm 8 is sleeved. There are pulleys 7 connected. The rotation of the two pulleys 7 drives the rotation of the two worms 8 at the same time. A belt 11 is connected to the rotation between the two pulleys 7. The pulley 7 rotates the belt 11 to rotate. The rotation of the belt 11 drives the other pulley 7 to rotate. One of the pulleys 7 rotates. A motor 6 is fixedly connected to the pulley 7. The starting motor 6 drives one of the pulleys 7 to rotate. There are a number of drawers 2 equidistantly arranged inside the cabinet 1.
