Description

Technical Field

[0001] The present invention relates to the technical field of power boxes, and specifically to a power box for power engineering. Background Art

[0002] A power box refers to a device used for distributing and controlling electric energy, usually including components such as switches, protection devices, and measuring instruments to ensure the safe, stable, and efficient operation of the power system. The power box is also known as a distribution box or an electric control box, which is a device integrating electrical components such as switches, protection devices, and measuring instruments. Its main function is to distribute, control, and protect electric energy to ensure that the electric energy can be safely and stably transmitted to each electrical device. In the power system, the power box is an important component, undertaking the key tasks of distributing and controlling electric energy.

[0003] A power box is a device for distributing electric energy, and contains multiple electrical components inside, such as circuit breakers, fuses, contactors, etc. During the process of receiving current from the power source and distributing the electric energy to different load electrical appliances, these electrical components will generate a certain amount of heat. If the heat accumulates too much, it will cause the component temperature to be too high, and may even cause the component to burn out, thus affecting the normal operation of the entire power box.

[0004] In addition, the high-temperature environment will also accelerate the aging of electrical components, shorten their service life, and increase the failure rate. Therefore, in order to ensure the normal operation of the power box and extend its service life, effective heat dissipation measures must be taken to timely dissipate the heat generated inside and keep the components within the appropriate working temperature range.

[0005] In the prior art, in order to reduce the temperature inside the power box, ventilation holes are generally provided on the power box. Although it has a certain heat dissipation function, its effect is not good. In addition, due to the ventilation holes making the power box conduct with the outside world for a long time, dust will also enter the box through the ventilation holes. A large amount of dust accumulates inside the power box, which not only affects the normal heat dissipation of the power box, reduces the insulation performance, but also will cause failures and increase potential safety hazards.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] In this solution, the two provided sealing components can respectively seal the air inlet and the air outlet, thus preventing dust from entering the cabinet when heat dissipation is not required. When the temperature inside the cabinet is too high and heat dissipation is needed, the driving component is activated. The driving component and the connecting rod cooperate with each other to make the two sealing components act synchronously, so that the air inlet and the air outlet are in an open state, that is, the cabinet is in communication with the outside world. At the same time, the heat dissipation component will work driven by the driving component, continuously blowing cold air into the cabinet through the air inlet, thereby taking away the heat inside the cabinet and achieving rapid cooling. In addition, the driving component will also drive the air sweeping component to act through the transmission structure. The operating air sweeping component will reciprocally guide the cold air entering the cabinet through the air inlet up and down, thereby enhancing the cooling effect of the cold air on the inside of the cabinet. When the temperature inside the cabinet drops, the driving component stops operating, and the two sealing components will reset, so that the air inlet and the air outlet return to the closed state again to prevent dust from entering the cabinet.

[0031] In this application, through the mutual mechanical cooperation among the provided sealing component, heat dissipation component, driving component, air sweeping component and transmission structure, when heat dissipation is required, the cabinet switches from the sealed state to the state of being in communication with the outside world, and continuously blows cold air into the cabinet. At the same time, it can reciprocally guide the cold air blown into the cabinet up and down. When the temperature of the cabinet drops, it returns to the sealed state. This solution not only improves the heat dissipation efficiency, but also avoids the situation where the cabinet is in communication with the outside world for a long time and dust enters the cabinet, reducing potential safety hazards.

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] In addition, the components in the present invention are referred to as "fixed to" or "disposed on" another component, which can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0049] Please refer to Figures 1 to 14 , in an embodiment of the present invention, a power box for a power project includes a cabinet body 1, an air inlet 101 and an air outlet 102 symmetrically arranged on the side walls of the cabinet body 1 on the left and right. Two sealing components are symmetrically arranged on the cabinet body 1. The two sealing components can respectively close the air inlet 101 and the air outlet 102. The two sealing components are connected by a connecting rod 2;

[0050] A heat dissipation component is arranged on the cabinet body 1. The heat dissipation component is located at the air inlet 101. When the heat dissipation component operates, it can blow the air outside the cabinet body 1 towards the air inlet 101;

[0051] A driving component is arranged on the cabinet body 1, and the driving component is respectively connected to the heat dissipation component and one of the sealing components. When the driving component operates, the heat dissipation component will act, and one of the sealing components will drive the other sealing component to act synchronously through the connecting rod 2, so that the air inlet 101 and the air outlet 102 are in an open state;

[0052] A wind sweeping component is arranged on the cabinet body 1 and at the air inlet 101. The wind sweeping component is connected to the driving component through a transmission structure. When the driving component operates, the wind sweeping component will cooperate with the driving component through the transmission structure to be able to guide the cold air entering the cabinet body 1 through the air inlet 101 up and down reciprocally.

[0053] In this solution, the two provided sealing components can respectively seal the air inlet 101 and the air outlet 102, thereby preventing dust from entering the cabinet 1 when heat dissipation is not required. When the temperature inside the cabinet 1 is too high and heat dissipation is needed, the driving component is activated. The driving component and the connecting rod 2 cooperate with each other to make the two sealing components act synchronously, so that the air inlet 101 and the air outlet 102 are in an open state, that is, the cabinet 1 is in communication with the outside world. At the same time, the heat dissipation component will work driven by the driving component, continuously blowing cold air into the cabinet 1 through the air inlet 101, thereby taking away the heat inside the cabinet 1 and achieving rapid cooling. In addition, the driving component will also drive the air sweeping component to act through the transmission structure. The operating air sweeping component will reciprocally guide the cold air entering the cabinet 1 through the air inlet 101 up and down, thereby enhancing the effect of the cold air in cooling the cabinet 1. When the temperature inside the cabinet 1 decreases, the driving component stops operating, and the two sealing components will reset, so that the air inlet 101 and the air outlet 102 return to the closed state again to prevent dust from entering the cabinet 1.

[0054] Please refer to Figure 3 、 Figure 4 、 Figure 11 The sealing component includes a frame plate 3 and a plurality of louver blades 4 stacked layer by layer from bottom to top. The frame plate 3 is fixedly connected to the cabinet 1, and one ends of the plurality of louver blades 4 are all rotatably connected to the inner wall of the frame plate 3;

[0055] Two adjacent louver blades 4 are rotatably connected through a connecting plate 5, and the plurality of connecting plates 5 are arranged at the other ends of the plurality of louver blades 4;

[0056] The connecting rod 2 is horizontally arranged, and two ends of the connecting rod 2 are respectively rotatably connected to the other end of one of the louver blades 4 near the air inlet 101 and the other end of one of the louver blades 4 near the air outlet 102.

[0057] In this embodiment, since the plurality of louver blades 4 are stacked layer by layer from bottom to top and one ends of them are all rotatably connected to the inner wall of the frame plate 3, and two adjacent louver blades 4 are rotatably connected through a connecting plate 5, when one of the louver blades 4 rotates to a horizontal state, the other plurality of louver blades 4 will also rotate to the horizontal state through the plurality of connecting plates 5;

[0058] Also, because the connecting rod 2 is horizontally arranged, and the other end of one of the louver blades 4 near the air inlet 101 and the other end of one of the louver blades 4 near the air outlet 102 are rotatably connected through the connecting rod 2, when one of the louver blades 4 near the air inlet 101 rotates to the horizontal, one of the louver blades 4 near the air outlet 102 will also rotate to the horizontal through the connecting rod 2, so that the air inlet 101 and the air outlet 102 are in an open state.

[0059] Please refer to Figure 6 and Figure 7 , the heat dissipation component includes a housing 6 fixed on the cabinet 1 and located at the air inlet 101, and a rotating shaft 7 rotatably arranged on the housing 6;

[0060] An impeller 8 is fixedly arranged on the outer wall of the rotating shaft 7, and a first bevel gear 9 is fixedly arranged at one end of the rotating shaft 7.

[0061] In this embodiment, since the impeller 8 is fixedly arranged on the outer wall of the rotating shaft 7 and the first bevel gear 9 is fixedly arranged at one end of the rotating shaft 7, when the first bevel gear 9 rotates, the rotating shaft 7 will drive the impeller 8 to rotate, and the rotating impeller 8 can blow air into the cabinet 1 through the air inlet 101.

[0062] Please refer to Figure 6 and Figure 9 and Figure 13 , the driving component includes a rotating rod 10 vertically rotatably arranged on the cabinet 1 and a second bevel gear 11 fixedly arranged at one end of the rotating rod 10, and the second bevel gear 11 meshes with the first bevel gear 9;

[0063] A motor 12 is fixedly arranged on the cabinet 1, and the output end of the motor 12 is fixedly connected to the other end of the rotating rod 10.

[0064] In this embodiment, since the second bevel gear 11 fixed at one end of the rotating rod 10 meshes with the first bevel gear 9, when the rotating rod 10 rotates, the second bevel gear 11 will drive the first bevel gear 9 to rotate;

[0065] Also, because the other end of the rotating rod 10 is fixedly connected to the output end of the motor 12, when the motor 12 is started, the output end of the motor 12 will drive the rotating rod 10 to rotate.

[0066] Please refer to Figure 6 and Figure 9 and Figure 13 , retaining rings 13 and discs 14 are fixedly arranged on the outer wall of the rotating rod 10 from top to bottom, a rotating seat 15 is movably arranged on the outer wall of the rotating rod 10, and the rotating seat 15 is located between the retaining ring 13 and the disc 14;

[0067] A frame 16 is rotatably arranged on the outer wall of the rotating seat 15, a spring 17 is sleeved on the outer wall of the rotating rod 10, and both ends of the spring 17 are abutted against the retaining ring 13 and the rotating seat 15 respectively.

[0068] In this embodiment, due to the presence of the spring 17 and it being in a compressed state, the swivel base 15 will always have a tendency to move towards the disc 14; and because the frame body 16 is rotatably arranged on the swivel base 15, therefore, the frame body 16 will also have a tendency to move towards the disc 14 driven by the swivel base 15.

[0069] Please refer to Figure 6 、 Figure 9 、 Figure 13 , a chute 18 is provided on the disc 14 along its diameter direction, the number of the chutes 18 is multiple, and the multiple chutes 18 are evenly distributed;

[0070] A T-shaped block 19 is slidably arranged inside each of the multiple chutes 18, and a connecting rod 20 is rotatably connected between each of the multiple T-shaped blocks 19 and the frame body 16.

[0071] In this embodiment, since a connecting rod 20 is rotatably connected between each of the multiple T-shaped blocks 19 and the frame body 16, and the multiple T-shaped blocks 19 are slidably arranged in the multiple chutes 18 provided along the diameter direction of the disc 14, wherein, due to the elastic force of the spring 17, the multiple T-shaped blocks 19 are all located at one end of the chute 18 close to the center of the disc 14;

[0072] Also, because the disc 14 is fixed on the rotating rod 10, when the rotating rod 10 rotates, the disc 14 will also rotate accordingly. As the rotation speed of the rotating rod 10 increases, the disc 14 will cause the multiple T-shaped blocks 19 to generate centrifugal force, so that the multiple T-shaped blocks 19 will slide towards the end away from the center of the disc 14 in the multiple chutes 18. The sliding T-shaped blocks 19 will drive the frame body 16 to rotate and move upward through the connecting rod 20; and because the frame body 16 and the swivel base 15 are rotationally matched, therefore, the frame body 16 will drive the swivel base 15 to move upward.

[0073] Please refer to Figure 9 、 Figure 11 , an L-shaped rod 21 is fixedly arranged on the swivel base 15, and a connecting column 22 is rotatably connected between the L-shaped rod 21 and the other end of one of the louvers 4 close to the air inlet 101;

[0074] A sealing cover 23 is arranged on the outer wall of the cabinet body 1, and the sealing cover 23 wraps the driving assembly inside it.

[0075] In this embodiment, since an L-shaped rod 21 is fixedly arranged on the swivel base 15, and a connecting column 22 is rotatably connected between the L-shaped rod 21 and the other end of one of the louvers 4 close to the air inlet 101, when the swivel base 15 moves upward, the connecting column 22 will drive one of the louvers 4 close to the air inlet 101 to rotate to a horizontal state;

[0076] The provided sealing cover 23 is used to wrap the driving component to prevent external interference with the operating driving component.

[0077] Please refer to Figure 6 、 Figure 10 、 Figure 14 , the air-sweeping component includes a U-shaped frame 24 fixedly arranged on the inner wall of the cabinet body 1 and a plurality of air guide plates 25 rotatably arranged on the U-shaped frame 24. One ends of two adjacent air guide plates 25 are rotatably connected through a connecting piece;

[0078] A rotating column 26 is vertically rotatably arranged on the cabinet body 1. A sleeve 27 is movably sleeved on the outer wall of the rotating column 26. A ball 28 is rollingly fitted inside the sleeve 27. A track groove 2601 is formed on the outer wall of the rotating column 26 along its length direction, and the ball 28 is also rollingly fitted in the track groove 2601.

[0079] In this embodiment, since a plurality of air guide plates 25 are rotatably arranged on the U-shaped frame 24, and one ends of two adjacent air guide plates 25 are rotatably connected through a connecting piece, when one of the air guide plates 25 swings up and down reciprocally, a plurality of air guide plates 25 will swing up and down reciprocally synchronously, thereby guiding the cold air up and down;

[0080] Also, because the ball 28 is rollingly fitted inside the sleeve 27, and the ball 28 is also rollingly fitted in the track groove 2601 formed on the outer wall of the rotating column 26 along its length direction, when the rotating column 26 rotates and the sleeve 27 cannot rotate, the sleeve 27 will move vertically reciprocally.

[0081] Please refer to Figure 10 , a column 29 is fixedly arranged on the outer wall of the sleeve 27. The column 29 and one of the air guide plates 25 are rotatably connected through a linkage rod 30.

[0082] In this embodiment, since the column 29 is fixedly arranged on the sleeve 27, and the column 29 and one of the air guide plates 25 are rotatably connected through the linkage rod 30, the sleeve 27 cannot rotate, and when the sleeve 27 moves vertically reciprocally, it will also drive one of the air guide plates 25 to swing up and down reciprocally through the linkage rod 30.

[0083] Please refer to Figure 6 , the transmission structure includes a first transmission wheel 31 fixedly arranged on the rotating rod 10 and a second transmission wheel 32 fixedly arranged on the rotating column 26. The first transmission wheel 31 and the second transmission wheel 32 are connected by a belt 33.

[0084] In this embodiment, since the first transmission wheel 31 fixed on the rotating rod 10 and the second transmission wheel 32 fixed on the rotating column 26 are connected by a belt 33, when the rotating rod 10 rotates, the rotating column 26 will rotate accordingly.
