Description

Technical Field

[0001] The present application relates to the technical field of line detection equipment, and more specifically, to an electric drive fault detection device. Background Art

[0002] Electric traction refers to a method of using an electric motor to drive the working mechanism of production machinery. It involves a power source, an electric motor, control equipment, and a transmission mechanism. To achieve a specific process, the motor must rotate in different ways, as required by the process. These circuits, connected to the control equipment to achieve these requirements, are the electric traction control circuits. The safe operation of power circuits is crucial. However, during use, power circuits can become damaged due to various factors, such as scratches, wear, and corrosion, which can seriously affect their safe operation.

[0003] The document with prior art publication number CN 220019428 U provides an electric traction fault line detection device, which unwinds the line from a unwinding roller, passes through an opening at one end of the shell into the shell, and then passes through the opening at the other end of the shell and is rewound by a reeling roller. A first motor can drive the reeling roller to rotate. When the line is in the shell, it passes between each image acquisition component, and each image acquisition component takes pictures of the line from multiple angles. The controller determines whether the line is damaged based on the line images collected by the image acquisition component. When the line is damaged, the controller controls the first motor to shut down and controls the alarm component to sound an alarm. The staff can know that the line is damaged. In this way, the surface of the power line can be inspected to improve the safety of the power line during operation.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, when it relies solely on two brush rollers to clean the line surface, there will be cleaning dead corners in the upper and lower areas between the two brush rollers, resulting in incomplete cleaning.

[0005] In view of this, we propose an electric traction fault detection device. Utility Model Content
