Electrostatic grounding device capable of ensuring tank truck to be effectively grounded

Abstract

The invention discloses an electrostatic grounding device capable of ensuring a tank truck to be effectively grounded. The electrostatic grounding device comprises a resistance detection module, a capacitance detection module, a controller, an alarm, a clip and a wiring board. The wiring board is at least provided with four wiring terminals, a first wiring terminal and a second wiring terminal are respectively connected with two clip heads of the clip, and a third wiring terminal and a fourth wiring terminal are connected with a grounding stud. The first wiring terminal is respectively connected with the resistance detection module and the capacitance detection module, the resistance detection module and the capacitance detection module are respectively connected with the controller, the controller is connected with the fourth wiring terminal, the alarm is connected with the controller, a detection switching circuit, which is used for switching on or off the second wiring terminal and the third wiring terminal, is connected between the second wiring terminal and the third wiring terminal, and the detection switching circuit is connected with the controller. According to the electrostatic grounding device capable of ensuring the tank truck to be effectively grounded, the phenomenon of poor grounding can be judged, an operator is prompted in a manner of audible alarm, whether the clip is connected onto a main body of the truck or not can be judged, and the circumstances that the clip is not connected with the truck or in virtual connection with the truck are then avoided.

Description

technical field [0001] The invention relates to an electrostatic grounding device, in particular to an electrostatic grounding device capable of ensuring effective grounding of tank cars. Background technique [0002] In the process of loading and unloading oil at gas stations and oil depots, the friction between the oil and the tank will generate static electricity in real time, and the operation of the machine will also generate static electricity. In order to prevent unsafe hazards caused by excessive static electricity, during the process of loading and unloading oil, timely Ground the tank truck body to conduct away excess static electricity. The grounding of the tank truck body requires the use of an electrostatic grounding device. The grounding clamp is clamped to the vehicle body, and the static electricity is guided away through the wire connected to the ground. The existing equipment cannot judge whether the grounding clamp is reliable and in contact with the vehic...

Problems solved by technology

The grounding of the tank truck body requires the use of an electrostatic grounding device. The grounding clamp is clamped to the vehicle body, and the static electricity is guided away through the wire connected to the ground. The existing equipment cannot judge whether the grounding clamp is reliable and in contact with the vehicle body. Good, and occasionally the grounding clip is clamped to the handle attached to the main body of the tanker, or the place where the connection with the main body of the tanker is not good, and there are situations where the operator does not operate according to the specifications and clamps the grounding clip on the vehicle. None of the above situations can Effective grounding, conduct away the generated static electricity
