Description

Technical Field

[0001] This utility model relates to the field of control device technology, and in particular to an electrical automation control device. Background Technology

[0002] Electrical control devices are generally referred to as secondary control circuits for electrical equipment. Different equipment has different control circuits, and the control methods for high-voltage electrical equipment and low-voltage electrical equipment are also different. Specifically, an electrical control system is a combination of several electrical components used to control one or more objects, thereby ensuring the safe and reliable operation of the controlled equipment. Most electrical control devices are placed in specific areas for personnel to use.

[0003] Existing electrical automation control devices, such as the one disclosed in Chinese Utility Model Publication No. CN216351884U, include an electrical automation control device, which is L-shaped and has an electrical control device at the top front end. The electrical control device is rectangular and its bottom is placed in the middle of the top of the base. The electrical control device includes a cover plate with a radiator at the top center and a square groove at the rear end. The length of the square groove is the same as the lateral length at the upper rear end of the corner base. The corner base includes a base, which is U-shaped and its bottom center is fixedly connected to the middle of the top of the corner base. Symmetrical through holes are provided at the front ends of both sides of the base. Two limiting rings are provided, each with a circular block on its inner side. The circular blocks are respectively placed in the through holes on both sides of the base. The outer side of the limiting ring has an inner groove with six claw grooves. A through hole is provided in the middle of the side of the limiting ring, and a bearing is placed inside the through hole.

[0004] While the aforementioned patent can prevent natural tipping, it lacks a tipping alarm function and cannot provide warnings during manual handling, making it prone to tipping damage. Furthermore, it only dissipates heat through the upper cover and ventilation holes, resulting in poor heat dissipation and potentially causing excessively high internal temperatures and component aging.

[0005] Therefore, this application proposes an electrical automation control device. Utility Model Content
