Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet heat dissipation, and specifically relates to a temperature-sensing sweeping air-cooled switch cabinet. Background Technique

[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set as required, such as meters, automatic controls, motor magnetic switches, various AC contactors, etc. The main function of the switch cabinet is to switch, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in the power system.

[0003] There are many classification methods for switch cabinets. For example, they can be divided into mobile switch cabinets and fixed switch cabinets according to the installation method of the circuit breaker; or according to different cabinet structures, they can be divided into open switch cabinets, metal-enclosed switch cabinets, metal-enclosed armored switch cabinets, etc.

[0004] A large amount of heat is generated during the operation of the switch cabinet, which makes the internal temperature rise. If the heat cannot be dissipated, it will affect the service life of the equipment inside the switch cabinet. In the prior art, usually a radiator or a fan is installed at the bottom of the switch cabinet, and the heat inside the switch cabinet will be discharged from the heat dissipation port under the action of the fan. If the area of the heat dissipation port opened on the switch cabinet is small, due to the small opening, the heat will be difficult to be quickly dissipated; if the area of the heat dissipation port opened on the switch cabinet is large, the air circulation rate will be affected due to the large opening. Content of the Utility Model

[0005] The purpose of the utility model is to provide a temperature-sensing sweeping air-cooled switch cabinet to solve the problems put forward in the above background technique.

A chute is opened inside one side wall of the cabinet body. The chute is communicated with the ventilation port, and a conduction plate is slidably arranged inside the chute in a sliding fit manner.

[0008] An air guiding component is arranged on the other side wall of the cabinet body. The conduction plate is connected to the air guiding component through a rotating structure. When the air guiding component operates, the conduction plate will reciprocate up and down inside the chute under the mutual cooperation of the rotating structure and the air guiding component, so that the cold air generated by the air guiding component will pass through a larger space inside the cabinet body without affecting the flow rate.

The sliding column is located inside the arc-shaped groove and is in sliding fit with each other. An elastic sheet is arranged inside the arc-shaped groove, and the elastic sheet will make the sliding column always tend to be at the same horizontal height as the central rotating shaft of the louver.

[0020] As a further scheme of the utility model:

[0021] A first gear is rotatably arranged on the frame plate. The center of the first gear is rotatably connected to the center of one of the louvers. A second gear is rotatably arranged on the frame plate. The second gear meshes with the first gear;

[0037] Please refer to Figures 1 to 8 , in the embodiment of the present invention, a temperature-sensing sweeping type heat dissipation switch cabinet includes a cabinet body 1 and a ventilation opening 2 penetrating through one side wall of the cabinet body 1. A sliding groove 3 is opened inside one side wall of the cabinet body 1. The sliding groove 3 is communicated with the ventilation opening 2, and a conduction plate 4 is slidably disposed inside the sliding groove 3;

[0038] An air guiding assembly is disposed on the other side wall of the cabinet body 1. The conduction plate 4 is connected to the air guiding assembly through a rotating structure. When the air guiding assembly operates, the conduction plate 4 will reciprocate up and down inside the sliding groove 3 under the mutual cooperation of the rotating structure and the air guiding assembly, so that the cold air generated by the air guiding assembly will pass through a larger space inside the cabinet body 1 without affecting the flow rate;

[0039] A wind-sweeping component is further arranged between the conducting plate 4 and the cabinet body 1. The wind-sweeping component includes a frame plate 17 arranged inside the conducting plate 4 and a plurality of louvers 5 rotatably arranged inside the frame plate 17. The wind-sweeping component will swing back and forth intermittently for the plurality of louvers 5 during the process of the conducting plate 4 moving up and down reciprocally.

[0040] In this solution, during the operation of the air induction component, air can be accelerated and blown into the cabinet body 1. At the same time, the rotating structure will cooperate with the air induction component, so that the conducting plate 4 will move up and down reciprocally inside the sliding groove 3, thereby continuously changing the position where the ventilation opening 2 is in communication with the cabinet body 1, so that a larger space inside the cabinet body 1 can be passed through by the cold air without affecting the flow rate of the cold air; in addition, the wind-sweeping component also swings back and forth intermittently for the plurality of louvers 5 during the process of the conducting plate 4 moving up and down reciprocally, so as to discharge the heat at the top and bottom of the cabinet body 1.

[0041] Wherein, the area of the conducting plate 4 is larger than the area of the ventilation opening 2, so that the cabinet body 1 can only communicate with the outside through the frame plate 17 on the conducting plate 4.

[0042] As a further solution of the present utility model, the rotating structure includes a bracket 6 arranged on the other side wall of the cabinet body 1. A rotating rod 7 is horizontally rotatably arranged between the bracket 6 and the cabinet body 1. A U-shaped frame 8 is arranged on the rotating rod 7.

[0043] In this embodiment, as Figure 7 shown, when the rotating rod 7 rotates, the U-shaped frame 8 will rotate following the rotating rod 7 as the rotation center; on the one hand, the bracket 6 is used to communicate the other side of the cabinet body 1 with the outside, and on the other hand, it is used to horizontally rotatably support the rotating rod 7 in cooperation with the cabinet body 1.

[0044] As a further solution of the present utility model, a sleeve 9 is rotatably arranged on the U-shaped frame 8. A cylinder 10 is horizontally arranged on the side wall of the frame plate 17. A transmission rod 11 is arranged on the outer wall of the sleeve 9. One end of the transmission rod 11 is rotatably connected to the outer wall of the cylinder 10.

[0045] In this embodiment, during the rotation of the rotating rod 7, the frame plate 17 will drive the conducting plate 4 to move up and down reciprocally inside the sliding groove 3 through the mutual cooperation of the cylinder 10, the transmission rod 11 and the sleeve 9 with the U-shaped frame 8, thereby continuously changing the position where the ventilation opening 2 is in communication with the cabinet body 1.

[0046] As a further solution of the present utility model, the air induction component includes an impeller 12 arranged on the outer wall of the rotating rod 7 and a motor 13 installed on the other side wall of the cabinet body 1;

[0047] The output end of the motor 13 is provided with a driving pulley 14, and the outer wall of the rotating rod 7 is provided with a driven pulley 15. The driving pulley 14 and the driven pulley 15 are connected by a belt 16.

[0048] In this embodiment, when the motor 13 is started, the output end of the motor 13 will drive the driving pulley 14 to rotate. During this process, the rotating rod 7 will rotate following the driving pulley 14 through the driven pulley 15 and the belt 16.

[0049] During the rotation of the rotating rod 7, the impeller 12 will rotate following the rotating rod 7, thereby driving the air at the bracket 6 to rotate rapidly and blow into the interior of the cabinet 1.

[0050] As a further solution of the present invention, the air-sweeping assembly further includes a plurality of connecting rods 18. One side of the ends of two adjacent louvers 5 is movably connected through the connecting rod 18, so that when any one of the louvers 5 rotates, the others will follow.

[0051] One end of one of the louvers 5 is provided with a sliding column 19. An arc-shaped groove 20 concentric with the central axis of the louver 5 is formed on the inner side wall of the frame plate 17. The sliding column 19 is located inside the arc-shaped groove 20 and is in sliding fit with each other. An elastic sheet 21 is arranged inside the arc-shaped groove 20, and the elastic sheet 21 will make the sliding column 19 always tend to be at the same horizontal height as the central axis of the louver 5.

[0052] In this embodiment, since one side of the ends of two adjacent louvers 5 is movably connected through the connecting rod 18, when any one of the louvers 5 rotates, the others will follow.

[0053] Moreover, because the sliding column 19 arranged on one of the louvers 5 makes the louver 5 always tend to be in a horizontal state under the action of the arc-shaped groove 20 and the elastic sheet 21, the other plurality of louvers 5 will also always tend to be in a horizontal state under the action of the plurality of connecting rods 18.

[0054] As a further solution of the present invention, a first gear 22 is rotatably arranged on the frame plate 17. The center of the first gear 22 is rotatably connected to the center of one of the louvers 5. A second gear 23 is rotatably arranged on the frame plate 17, and the second gear 23 meshes with the first gear 22.

[0055] A fixing frame 24 is arranged inside the cabinet 1. A lower toothed plate 25 and an upper toothed plate 26 are symmetrically arranged on the side of the fixing frame 24 close to the second gear 23, and the lower toothed plate 25 and the upper toothed plate 26 correspond to the position of the second gear 23.

[0056] In this embodiment, during the process that the frame plate 17 drives the conduction plate 4 to move downward in the sliding groove 3, the second gear 23 will engage with the lower tooth plate 25 and rotate counterclockwise. At the same time, the first gear 22 will drive one of the louvers 5 to rotate clockwise under the rotation of the second gear 23, so that a plurality of louvers 5 are all tilted upward, which is more conducive to the discharge of the heat at the bottom of the cabinet body 1;

[0057] Similarly, during the process that the frame plate 17 drives the conduction plate 4 to move upward in the sliding groove 3, the second gear 23 will engage with the upper tooth plate 26 and rotate clockwise. At the same time, the first gear 22 will drive one of the louvers 5 to rotate counterclockwise under the rotation of the second gear 23, so that a plurality of louvers 5 are all tilted downward, which is more conducive to the discharge of the heat at the top of the cabinet body 1;

[0058] During the process that the second gear 23 engages with the lower tooth plate 25 and the upper tooth plate 26 respectively, the rotating louvers 5 will drive the sliding column 19 to slide in the arc-shaped groove 20 and squeeze the elastic piece 21 to cause elastic deformation; when the second gear 23 separates from the lower tooth plate 25 and the upper tooth plate 26, under the action of the elastic piece 21, a plurality of louvers 5 will remain in a horizontal state.

[0059] As a further solution of the present utility model, a temperature sensor 27 and a controller 28 are respectively arranged inside the cabinet body 1, and the temperature sensor 27 and the motor 13 are both electrically connected to the controller 28.

[0060] In this embodiment, when the temperature sensor 27 monitors that the temperature inside the cabinet body 1 reaches a preset value, the temperature sensor 27 will send an electrical signal to the controller 28, and after receiving the signal, the controller 28 will start the motor 13 to perform heat dissipation operations.
