Description
Technical Field
[0001] This utility model belongs to the technical field of refueling equipment, and mainly relates to a telescopic integrated electrostatic discharge device for gas stations. Background Technology
[0002] Petroleum products possess hazardous properties such as flammability, explosiveness, evaporation, flowability, leakage, static electricity accumulation, thermal expansion, and a certain degree of toxicity. Industrial and construction sectors rely heavily on petroleum products for sales, and these companies generally lack the capacity to construct oil tanks to meet their needs. They primarily rely on portable containers (oil drums) of approximately 220L to transfer petroleum products. Currently, the commonly used refueling method, namely splash-type refueling, generates significant static electricity through intense collisions and friction between oil particles and between the oil and the container walls. Meanwhile, according to relevant data, the average flow velocity of the oil is 2.6 m / s, and the oil surface potential is 2300 V; the average flow velocity is 1.7 m / s, and the oil surface potential is 580 V. GB 50156-2012 (2014 edition) specifies a fuel dispenser flow rate of 50 L / min, and the calculated flow velocity is 0.7351 m / s [GB 50156-2002 (2006 edition) specifies a fuel dispenser flow rate of 60 L / min, and the calculated flow velocity is 0.8822 m / s. Standards from different eras have continuously improved the safety of refueling operations]. This meets the requirement of AQ2310-2007 that the flow velocity is less than 1 m / s. However, in the case of spray-type fuel dispensing, the oil is accelerated out of the hole. During the fall, gravity accelerates the oil. The larger the container and the larger the fall space, the faster the speed will become, possibly exceeding 1 m / s, thus creating a danger.
[0003] The nozzles of existing gas station refueling nozzles are short, which can cause splashing during the refueling of mobile containers, easily generating and accumulating static electricity and causing accidents. Utility Model Content

[0031] Specific operating instructions:
