Intelligent modular electric shock proof angle grinder

Abstract

The invention relates to an intelligent modular electric shock proof angle grinder, belonging to the technical field of angle grinders. An anti-shock power supply box and a power supply wire with a shielding layer are adopted, so that the angle grinder is connected to the anti-shock power supply box through the power supply wire with the shielding layer; the anti-shock power supply box comprises apower supply current transforming unit and an intelligent detection unit; the power supply current transforming unit is connected to the mains supply to output a direct current to the angle grinder,and the intelligent detection unit detects whether the power supply wire and the angle grinder occur electric leakage or not. The anti-shock power supply box and the power supply wire with the shielding layer are adopted, and the angle grinder is connected to the anti-shock power supply box through the power supply wire with the shielding layer; therefore, when the shield layer is exposed due to the wear of the power supply wire skin, a detection module of the intelligent detection unit can detect the contact between the shield layer of the power supply wire and the object or position to be inspected; so that an alarm signal can be sent in time and the power supply can be cut off in time, and personal injury and equipment damage accidents caused by the electric leakage of the angle grindercan be avoided.

Description

technical field [0001] The invention relates to an intelligent modular anti-shock angle grinder, which belongs to the technical field of angle grinders. Background technique [0002] Angle grinder is an electric tool that is often used in our daily production and life, and is widely used in various industrial and mining enterprises and construction sites. In the prior art, the traditional angle grinder is directly powered by the mains. When the insulation is damaged and the human body touches the exposed live power line, an electric shock accident occurs, causing personal injury and equipment damage. Because the power cord of the angle grinder is exposed to the outside for a long time, the environment in which it is located is likely to cause the sheath of the power cord to wear and even leak electricity, resulting in safety accidents, and often cause leakage and electric shock accidents due to the entry of rainwater. In large-scale construction sites, many angle grinders a...

Problems solved by technology

In the prior art, the traditional angle grinder is directly powered by the mains. When the insulation is damaged, the human body touches the exposed live power line and an electric shock accident occurs, causing personal injury and equipment damage.

Since the power cord of the angle grinder is exposed to the outside for a long time, the environment in which it is located is likely to cause the sheath of the power cord to wear and even leak electricity, resulting in safety accidents, and often cause leakage and electric shock accidents due to the entry of rainwater.

In large-scale construction sites, many angle grinders are used. When an electric leakage or electric shock accident occurs, it is not easy to find out which angle grinder or which part of the circuit has a problem. If the fault cannot be eliminated in time, it may easily cause equipment burnout, fire and other consequences. , serious and even casualty consequences
