Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainproof technology for electrical control cabinets, and in particular to a rainproof device for electrical control cabinets. Background Art
[0002] An electrical control cabinet is a device used for centralized control, protection, and distribution of electrical equipment. It typically includes various electrical components and accessories for controlling motors, generators, transformers, switching equipment, etc., in a power system. The rainproof function of an electrical control cabinet is to protect the control equipment from damage or malfunction caused by rainwater intrusion. In outdoor or humid environments, if the electrical control cabinet lacks proper rainproofing, rainwater may seep into the cabinet, leading to short circuits, equipment damage, or even the risk of electric shock.
[0003] In existing technologies, rain protection measures for electrical control cabinets typically involve installing a rain shield on top of the cabinet and sealing it with sealing materials. However, when electrical control cabinets are used outdoors for extended periods, they are susceptible to erosion from external environmental factors, which can damage the sealing materials and significantly reduce the cabinet's waterproofness, thus deteriorating its rainproof performance. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a rainproof device for an electrical control cabinet, comprising an electrical control cabinet body and a rain shield disposed directly above the electrical control cabinet body. The rain shield is fixedly installed directly above the electrical control cabinet body and has a drainage mechanism. A water-blocking groove is fixedly installed at the lower end of the electrical control cabinet body via a connecting rod. Support legs are fixedly installed on both sides of the lower surface of the water-blocking groove. Ventilation components are provided inside the water-blocking groove and inside the electrical control cabinet body.
[0005] As an improvement to the above technical solution, water outlet pipes are fixedly installed on both outer surfaces of the water-blocking groove, and the water outlet pipes are connected to the interior of the water-blocking groove.
[0006] As an improvement to the above technical solution, the drainage mechanism includes an arc-shaped plate fixedly installed on the top of the rain shield. Several equally spaced water guide grooves are provided on both sides of the upper surface of the rain shield, and the several water guide grooves are located on both sides of the arc-shaped plate. Both sides of the rain shield are provided with convex plates, and the convex plates and the rain shield are integrally formed. Several equally spaced water outlets are opened inside the convex plates, and each water outlet corresponds to a water guide groove.
[0007] As an improvement to the above technical solution, the ventilation component includes two fans fixedly installed inside the water baffle. Each of the two fans has an air inlet 2 below it, and the air inlet 2 is located at the bottom of the water baffle. A filter screen is fixedly installed inside the air inlet 2. The bottom of the electrical control cabinet body has several air inlets 1 distributed at equal intervals. The air inlets 1 are connected to the interior of the electrical control cabinet body. The fans are located directly below the air inlets 1. Each air inlet 1 has a waterproof and breathable membrane installed inside it.
[0008] As an improvement to the above technical solution, the ventilation component further includes grooves formed on the outer surfaces of both sides of the electrical control cabinet body. The grooves are provided with a number of equally spaced ventilation openings, and the ventilation openings are connected to the interior of the electrical control cabinet body. An inclined plate is provided above the grooves. The inclined plate is fixedly installed on the outer surface of the electrical control cabinet body, and the inclined plate forms a 30-degree angle with the horizontal.
[0009] Beneficial effects of the utility model:
[0010] By installing a rain shield directly above the electrical control cabinet and a drainage mechanism on it, rainwater can be effectively drained in a timely manner, preventing excessive accumulation and ingress into the cabinet. A water-retaining groove below the cabinet effectively prevents rainwater from splashing onto the ground and entering the cabinet, thus increasing the overall waterproofness. Furthermore, ventilation components are installed in both the water-retaining groove and the cabinet itself to maintain proper ventilation, preventing condensation inside the cabinet in humid environments and further enhancing its waterproof performance.
