Description

Technical Field

[0001] The utility model relates to the technical field of grounding detection devices for electric locomotives, and particularly relates to a grounding detection device for electric locomotives. Background Technique

[0002] The grounding detection device for electric locomotives is a key safety monitoring tool, specially designed to ensure that electric locomotives can safely and effectively conduct current into the ground during operation. The device monitors the grounding status in real time, detects the contact situation between the carbon brush and the rotating shaft of the electric locomotive, and ensures the integrity of the current loop. Once it detects problems such as carbon brush wear or other factors causing poor grounding, the device will promptly issue an alarm to prompt the staff to perform necessary maintenance or replacement, thereby avoiding electric locomotive failures and improving operation safety. In addition, such devices usually have good environmental adaptability, can reduce dependence on external power supplies, and reduce labor costs through automated monitoring, improving maintenance efficiency and economic benefits. Some advanced models also include a data recording function to help analyze historical data on the grounding status and optimize future maintenance plans.

[0003] After retrieval, the text of the publication number "CN220872639U" mentions that "the utility model discloses a grounding detection device for electric locomotives, which relates to the technical field of grounding detection devices for electric locomotives and includes a rear cover plate arranged at the rear end of the main body shell, and the main body shell is fixedly connected to the rear cover plate. The device can convert external solar energy into electrical energy for powering the alarm by installing a solar panel, greatly reducing the use cost of the device. Installing a compression spring can push the carbon brush to move, so that the carbon brush always fits with the rotating shaft of the electric locomotive. When the carbon brush wears to a certain extent, the monitoring board will gradually move, and then the monitoring board will contact the contact button, and then the alarm will sound, enabling the staff to know in time that the carbon brush needs to be replaced, avoiding the occurrence of the phenomenon that the electric locomotive is not grounded, and ensuring the safe driving of the electric locomotive. This device is not affected by external dust and debris and will not have an error reporting phenomenon. At the same time, it does not require the use of a displacement sensor, has a simple structure and low cost". When in use, it has a simple structure and low cost, but the above device is prone to being interfered by external electromagnetic signals and external vibrations during use, resulting in false alarms.

[0004] Therefore, we provide a grounding detection device for electric locomotives to solve the above problems. Content of the Utility Model

[0005] This application provides a grounding detection device for electric locomotives, which solves the problem that the device is prone to being interfered by external electromagnetic signals and external vibrations during use, resulting in false alarms.

[0006] This application provides a grounding detection device for electric locomotives, including a base and a working mechanism. The working mechanism is arranged above the base.

[0007] The working mechanism includes an anti-interference component arranged above the base. An anti-vibration component is arranged inside the anti-interference component.
