The utility model relates to the technical field of filling machines, and discloses a hazardous chemical substance filling machine with an anti-static structure, which comprises an outer frame, a roller conveyor belt is mounted on the surface of the outer frame, a portal frame is fixedly connected to the top of the outer frame, and an anti-static mechanism is mounted on one side of the portal frame. Extension blocks are fixedly connected to the two sides of the outer frame. According to the hazardous chemical substance filling machine with the anti-static structure, through the arrangement of the anti-static mechanism, when the hazardous chemical substance filling machine is used, a static voltmeter is installed on the surface of a portal frame, static voltage on the surface of equipment can be detected in real time, and when static electricity is too large, a signal can be transmitted to a PLC on one side; meanwhile, an electrode plate, a wire and a pestle are arranged on the surface of the portal frame, static electricity generated on the surface of the equipment can be guided into the ground, the anti-static capacity of the equipment is further enhanced, and the safety of the dangerous chemical filling process is guaranteed.

This utility model provides an electrostatic discharge (ESD) detection device for power transmission and distribution, including an electrostatic voltmeter. The ESD voltmeter is equipped with a probe, the upper end of which is fitted with a protective cap. A grounding wire is plugged into the grounding terminal of the ESD voltmeter, and a conductive clip is fixedly installed at the other end of the grounding wire. The ESD voltmeter is also equipped with a rangefinder assembly and a Y-shaped stop assembly. The rangefinder assembly includes a housing, with an infrared ranging sensor fixedly installed at the upper end of the housing. A display screen is fixedly installed on the side of the housing facing away from the infrared ranging sensor. The arrangement of the housing, display screen, and infrared ranging sensor in this utility model allows the user to find the effective detection distance, improving detection efficiency.
