Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to an electric control cabinet with a ventilation structure. Background Art

[0002] An electrical control cabinet, or electronic control cabinet, is a device used to house, control, and protect electrical equipment. It typically consists of one or more cabinets, each housing various electrical components such as switches, relays, contactors, and protectors. Electrical control cabinets are widely used in industries such as industry, construction, transportation, and communications. Ventilation-equipped cabinets ensure that heat generated by electrical equipment is dissipated promptly, maintaining optimal operating temperatures. Prolonged exposure to high temperatures can lead to performance degradation or even damage, shortening the lifespan of electrical equipment. Therefore, ventilation is crucial for electrical control cabinets.

[0003] A search revealed a publication numbered CN203457461U that discloses an electric control cabinet comprising a cabinet body and a cabinet door. A mounting plate for fixing the cabinet body is provided on the back of the cabinet body. A tenon-shaped sealing flange is provided around the cabinet door opening, and the cabinet door is snap-fitted to the sealing flange. A waterproof flange is provided around the cabinet top plate, and a louvered ventilation window connected to the upper portion of the cabinet body is provided below the waterproof flange. A tenon-shaped sealing flange is provided around the cabinet door opening, and a groove is provided on the sealing flange. A rubber layer is provided in the groove. The cabinet door snaps completely onto the flange, providing a good sealing effect. Conventional cabinet doors, closed within the cabinet body, are susceptible to water seepage at the hinge, seriously endangering the safety of the electronic equipment in the electric control cabinet. The utility model provides a waterproof flange around the top plate of the cabinet, and a louvered ventilation window connected to the upper part of the cabinet is provided below the waterproof flange. Not only is the ventilation effect good, but rainwater cannot invade the electric control cabinet, and the waterproof effect is good. In this application, the interior of the electric control cabinet is only ventilated through the louvered ventilation window. Such a setting will result in less than ideal ventilation of the electric control cabinet, and the heat generated during operation cannot be dissipated in time, resulting in increased equipment temperature, affecting performance and life.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 - Figure 2, the utility model provides an embodiment: an electric control cabinet with a ventilation structure, including a cabinet body 1, characterized in that: a ventilation hole 2 is opened inside the cabinet body 1, the top of the filter bin 4 is fixedly connected to an air supply pipe 5, the inner wall of the air supply pipe 5 is fixedly connected to a fan 6, the outer wall of the filter bin 4 is fixedly connected to a motor 7, the output end of the motor 7 is fixedly connected to a fan blade 8, both ends of the fan blade 8 are rotatably connected to the inside of the filter bin 4, the inner wall of the filter bin 4 is fixedly connected to a dust collecting plate 9, the inner wall of the filter bin 4 is fixedly connected to a guide plate 10, the inside of the filter bin 4 is fixedly connected to a filter plate 11, the inside of the filter bin 4 is fixedly connected to a diverter pipe 12, the outer wall of the diverter pipe 12 is fixedly connected to the top of the cabinet body 1, a ventilation component is provided inside the cabinet body 1, the ventilation component includes a ventilation plate 3, and the outer wall of the ventilation plate 3 is fixedly connected to the inside of the cabinet body 1;

[0024] Specifically, starting the fan 6 first is a key step. The function of the fan 6 is to suck the external air into the filter bin 4 through the air supply pipe 5. In this process, the motor 7 plays a power role, driving the fan blades 8 to rotate inside the filter bin 4, so that the air can diffuse to both sides along the direction of the guide plate 10. In the process of air flow, the dust collecting plate 9 inside the filter bin 4 plays a vital role. It can effectively adsorb the dust in the air, thereby ensuring that the air entering the filter plate 11 has undergone preliminary purification. The dust collecting plate 9 and the guide plate 10 work together to guide the purified air to the filter plate 11. The filter plate 11 is the core component of the air purification system, which purifies the air more deeply to ensure that the discharged air meets environmental protection standards. The air filtered by the filter plate 11 is finally evenly transported to the interior of the cabinet 1 through the diversion pipe 12, thereby realizing ventilation treatment of the internal environment of the cabinet 1.

[0025] Reference Figure 3 and Figure 4 The cabinet 1 is rotatably connected to a rotating shaft 21, the outer wall of the rotating shaft 21 is fixedly connected to an arc-shaped gear ring 13, the outer wall of the rotating shaft 21 is fixedly connected to an L-shaped plate 14, the outer wall of the L-shaped plate 14 is fixedly connected to a fixed block 15, the internal rotation of the fixed block 15 is connected to a telescopic rod 16, the outer wall of the telescopic rod 16 is provided with a spring 17, both ends of the spring 17 are fixedly connected to the outer wall of the fixed block 15, the outer wall of the L-shaped plate 14 is fixedly connected to a telescopic rod 2 18, the outer wall of the telescopic rod 2 18 is provided with a spring 2 19, one end of the spring 2 19 is fixedly connected to the outer wall of the L-shaped plate 14, and the other end of the spring 2 19 is fixedly connected to the L-shaped plate 20;

[0026] Specifically, the wiring harness is first pushed between the L-shaped plate 1 14 and the L-shaped plate 2 20. During this pushing process, the L-shaped plate 1 14 will drive the arc-shaped gear rings 13 on both sides to rotate. At the same time, the spring 17 will contract. When the wiring harness completely enters between the L-shaped plate 1 14 and the L-shaped plate 2 20, the spring 1 17 will begin to rebound. This rebound process will drive the two L-shaped plates 20 to fit together again, thereby realizing the collection of the wiring harness, making the wiring harness more orderly during the sorting process and avoiding the disorder of the wiring harness. However, when the number of wiring harnesses is too large, the L-shaped plate 1 14 and the L-shaped plate 2 20 will move relative to each other. At this time, the spring 2 19 will begin to stretch. The spring 2 19 will generate a contraction force during the stretching process. This contraction force can clamp and fix the wiring harness, so that even if the number of wiring harnesses is large, they can remain neat and orderly, avoiding entanglement and confusion of the wiring harness.

[0027] Working principle: When it is necessary to use an electric control cabinet with a ventilation structure, first start the fan 6 to suck the external air into the filter bin 4 through the air supply pipe 5, and at the same time drive the fan blades 8 to rotate inside the filter bin 4 through the output end of the motor 7, so that the air is blown to both sides along the guide plate 10. In this process, the dust in the air is adsorbed by the dust collecting plate 9 inside the filter bin 4, and at the same time, the air is sent to the filter plate 11 through the guide plate 10, and filtered by the filter plate 11. Finally, the filtered air is evenly transported to the inside of the cabinet 1 through the diversion pipe 12, and then the air circulation is realized in conjunction with the ventilation holes 2 and the ventilation plates 3 to ventilate the inside of the cabinet 1. Then the wiring harness inside the cabinet 1 is pushed between the two L-shaped plates 20 to between the L-shaped plates 1 14 and 20. This process will drive the arc-shaped gear rings 13 on both sides to rotate through the L-shaped plate 1 14, and at the same time make the spring 1 17 shrink. When the wiring harness completely enters between the L-shaped plate 1 14 and the L-shaped plate 2 20, the spring 1 17 rebounds, thereby driving the two L-shaped plates 20 to fit together again, and then collecting the wiring harness. When there are too many wiring harnesses, the L-shaped plate 1 14 and the L-shaped plate 2 20 will move relative to each other, thereby stretching the spring 2 19, and then the wiring harness is clamped and fixed by the contraction force generated by the stretching of the spring 2 19, thereby achieving the effect of wiring harness organization.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
