Description

Technical Field

[0002] Switchgear is an electrical product used to switch, control or protect the power generation, transmission, distribution, power conversion and consumption of the power system. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] At present, switch cabinets (circuit breaker switch cabinets) mainly include fixed switch cabinets (fixed cabinets), central or removable switch cabinets (handcart cabinets), inflatable cabinets (inflatable cabinets) and solid insulation switch cabinets. The above-mentioned high-voltage switch cabinets have their own advantages and disadvantages. The main function of the switch cabinet is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices.

[0004] Since a large number of electronic components are arranged in the switch cabinet, a lot of heat will be generated during use. If the accumulated heat is not discharged in time, the electronic components that are exposed to high temperature for a long time may accelerate aging and affect the service life of the switch cabinet. However, the existing switch cabinets generally have normally open heat dissipation holes. When dissipating the heat inside the cabinet, most of them use fans to blow air directly, so that the heat inside the switch cabinet is discharged from the heat dissipation holes. The heat dissipation effect of this heat dissipation method is general, and it may not be possible to achieve all-round cooling of the cabinet. Utility Model Content

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0042] See also Figures 1 to 8 In an embodiment of the utility model, a power switch cabinet with conduction delayed heat dissipation includes a cabinet body 1 and two first vents 101 and second vents 102 symmetrically arranged on the side walls of the cabinet body 1, wherein a plurality of shutters 2 are rotatably arranged inside the first vent 101, wherein the plurality of shutters 2 are mutually staggered and stacked and the first vent 101 is in a sealed state under the action of a reset structure, and two adjacent shutters 2 are connected by a connecting rod 3;

[0043] A driving mechanism is disposed behind the cabinet 1, an air induction component is disposed inside the second vent 102, a swing component is disposed inside the cabinet 1, the air induction component and the swing component are both connected to the driving mechanism, and the swing component is connected to any one of the plurality of shutters 2;

[0044] When the driving mechanism starts to start, the air induced component will run synchronously and accelerate the air circulation rate at the second vent 102, so that the air is blown into the interior of the cabinet 1. When the driving mechanism reaches a preset speed, the driving mechanism will drive the swing component to run, and the swing component will cause the louver 2 to swing back and forth, so that the cabinet 1 is connected to the outside world to facilitate the removal of internal heat.

[0045] In this solution, the air induction component can synchronously accelerate the air circulation rate at the second vent 102 when the driving mechanism starts to start, so that the air is blown into the interior of the cabinet 1. Then, when the driving mechanism reaches a preset speed, the swing component will follow the driving mechanism and drive the shutter 2 to swing back and forth, so that the cabinet 1 is connected to the outside through the first vent 101 to facilitate the evacuation of internal heat.

[0046] Since the first vent 101 is in a closed state when the air induction assembly is in operation, the cold air will first blow to the top and bottom of the cabinet 1, so that the interior of the cabinet 1 can be cooled in all directions, thereby improving the heat dissipation effect;

[0047] When the driving mechanism reaches a preset speed, the swing assembly drives the shutter 2 to swing back and forth, and the first vent 101 is in an open and closed state. At this time, the heat in the cabinet 1 is discharged from the first vent 101;

[0048] In summary, by delaying the turn-on of the cabinet 1 , the cabinet 1 can be cooled in all directions, so that the heat dissipation effect in the cabinet 1 is better.

[0049] As a further solution of the utility model, the driving mechanism includes a rotating rod 4 rotatably arranged on the rear side wall of the cabinet 1 and a rotating disk 5 movably arranged on the rotating rod 4;

[0051] In this embodiment, when the rotating rod 4 just starts to rotate, due to the low rotation speed, the first slide bar 7 has a small centrifugal force and cannot overcome the elastic force of the first spring 8, so that the first slide bar 7 and the first sleeve 6 are relatively stationary, that is, the roller 9 rotates normally in the rotating disk 5, and the rotating disk 5 does not rotate with it;

[0052] When the rotation speed of the rotating rod 4 reaches a preset value, the first slide bar 7 has a large centrifugal force, which can overcome the elastic force of the first spring 8, that is, the first slide bar 7 will further compress the first spring 8 and slide outward from the first sleeve 6, so that the roller 9 rotates while tightly contacting the inner wall of the turntable 5. When the roller 9 rotates to the slot 10, it will extend into the slot 10 and engage with each other. At this time, the turntable 5 will rotate with the rotating rod 4.

[0055] A first bevel gear 16 is disposed at one end of the first rotating shaft 13 .

[0056] In this embodiment, the motor 11 is started first, and the output end of the motor 11 will drive the rotating rod 4 to rotate, and the first pulley 12 will rotate following the rotating rod 4. During this process, the first rotating shaft 13 will rotate following the first pulley 12 through the second pulley 14 and the first belt 15. Since the first bevel gear 16 is arranged on the first rotating shaft 13, the first bevel gear 16 will also rotate.

[0057] As a further solution of the utility model, the swing assembly includes a rotating plate fixing frame 17 arranged on the inner wall of the cabinet 1, and the internal rotation of the rotating plate fixing frame 17 is matched with a rotating plate 18, and the rotating plate 18 is fixedly connected to the turntable 5 by a connecting column 19, and an eccentric column 22 is eccentrically arranged on one side wall of the rotating plate 18 away from the turntable 5.

[0058] In this embodiment, during the rotation of the turntable 5 , the rotating plate 18 will rotate along with the turntable 5 via the connecting column 19 , so that the eccentric column 22 rotates along with the turntable 18 .

[0059] As a further solution of the utility model, the swing assembly further includes a bracket 20 arranged on the inner wall of the cabinet 1 and a slider 21 slidably matched with the bracket 20, and a rotating rod 23 is movably arranged between the slider 21 and the eccentric column 22;

[0061] In this embodiment, since the slider 21 is rotatably connected to the eccentric column 22 via the rotating rod 23, and the slider 21 and the bracket 20 are slidably matched with each other, the slider 21 will slide back and forth on the bracket 20 when the eccentric column 22 rotates following the rotating plate 18.

[0062] Because the sliding column 25 rotatably connected to the side wall of one of the shutters 2 slides with the slide groove 24 provided on the side wall of the slider 21, during the reciprocating sliding of the slider 21, the sliding column 25 slides with the slide groove 24 to drive one of the shutters 2 to swing back and forth;

[0063] Since two adjacent shutters 2 are connected via the connecting rod 3, when one of the shutters 2 swings back and forth, all other shutters 2 will also swing back and forth.

[0064] As a further solution of the utility model, the air induced assembly includes a fixed frame 26 arranged inside the second vent 102, a second rotating shaft 27 is rotatably arranged at the center of the fixed frame 26, and an impeller 28 and a fourth pulley 31 are respectively arranged on the outer wall of the second rotating shaft 27.

[0065] In this embodiment, when the fourth pulley 31 rotates, the fourth pulley 31 will drive the impeller 28 to rotate through the second rotating shaft 27, thereby accelerating the air flow rate at the second ventilation port 102, so that the external air is blown into the interior of the cabinet 1.

[0066] As a further solution of the utility model, the air induction assembly also includes a third rotating shaft 29 rotatably arranged on the side wall of the cabinet 1, and the outer wall of the third rotating shaft 29 is provided with a third pulley 30, and the third pulley 30 and the fourth pulley 31 are connected by a second belt 32;

[0067] A second bevel gear 36 is disposed at one end of the third rotating shaft 29 , and the second bevel gear 36 and the first bevel gear 16 are meshed with each other.

[0068] In this embodiment, since the second bevel gear 36 and the first bevel gear 16 are meshed with each other, when the first bevel gear 16 rotates, the second bevel gear 36 will drive the third pulley 30 to rotate accordingly. When the third pulley 30 rotates, the fourth pulley 31 will rotate along with the third pulley 30 via the second belt 32.

[0069] As a further solution of the utility model, the reset structure includes a second sleeve 33 and a second slide rod 34 slidably matched with the second sleeve 33, one end of the second sleeve 33 is rotatably connected to the side wall of the cabinet 1, and one end of the second slide rod 34 is rotatably connected to the shutter 2 located at the bottom;

[0070] The second sleeve 33 is provided with a second spring 35 , and the second spring 35 makes the second sliding rod 34 always have a tendency to approach the second sleeve 33 .

[0071] In this embodiment, since the second spring 35 is in a compressed state, during the reciprocating swing of the shutter 2, the shutter 2 will drive the second slide bar 34 to slide and retract relative to the second sleeve 33, so that the second spring 35 is continuously switched between further compressed and released states;

[0072] When the shutter 2 stops swinging, due to the action of the second spring 35 , the shutter 2 returns to the initial state, that is, the first ventilation opening 101 is sealed.
