Description

Technical Field

[0001] The utility model relates to an alarm device for placing a fuel tank cap, belonging to the technical field of refueling operations. Background Art

[0002] In the daily operation of a gas station, opening the fuel tank cap is a normal operation. After most vehicle fuel tank caps are opened, due to the lack of a fixed area for placing the fuel tank cap or good storage habits, the fuel tank cap is randomly placed in idle areas such as the ground of the fueling island, the multifunctional box, the gantry of the fuel dispenser, the trash can, and the trunk of the vehicle. The placement method is not only unsightly and non-standard, but also likely to cause the situation of forgetting to replace the fuel tank cap. Especially when there are fewer gas station service personnel, due to the busy scene and serving multiple vehicles at the same time, the fueler shuttles back and forth, and the frequency of abnormal service events of forgetting to cover the fuel tank cap is relatively high. Some employees, especially newly recruited employees, are also prone to such service habit events in the early stage of actual operation. Since it is troublesome to place the fuel tank cap and relies on spontaneous habits and detailed reminders, it indirectly leads to a decrease in the initiative of fueling employees to open and close the fuel tank for customers, and frequent occurrences of events such as the fuel tank cap not being rotated in place or being lost.

[0003] Forgetting to cover the fuel tank cap will cause three major problems: 1. Safety problems: During the driving process of a gasoline vehicle, shaking and jittering may generate small friction sparks or other static electricity at any time, which may trigger a safety accident at any time. As long as the fuel tank opening is open and there is an open flame or static electricity around, there will be serious safety problems, which will also cause great harm or potential hazards to people, vehicles or other things around. If the vehicle is parked in a closed space such as a garage, the volatilized oil gas will cause people to breathe poisoning, which is more like a time bomb; in case of rain or car wash, water runs into the fuel tank, which will cause problems with the power system, with high repair costs and high risk factors. 2. Fuel consumption: Since gasoline is a volatile substance and the fuel tank cap is not covered, the volatility is large, resulting in high fuel consumption. Especially when the vehicle is in motion, the open fuel tank opening will form an air current against the wind, creating a circulation loop between the internal space of the fuel tank and the outside world, accelerating the volatilization of the gas, just like installing a fan on the surface of the oil product to blow, doubling both the fuel consumption and the risk factor. 3. Pollution problems: Due to the open fuel tank cap without barrier, the oil gas contacts the atmosphere, and the volatilized oil gas enters the air, causing air pollution, which will affect the health of the contactors and damage the atmospheric environment.

[0021] The communication module of the fuel tank cap placement alarm device includes a WIFI, Bluetooth or GPRS module.

[0022] The fuel tank cap placement alarm device further includes a pressure sensor arranged on the fuel gun. When the fuel gun is hung, a signal is transmitted to the fuel dispenser gun hanging closed circuit module through the pressure sensor; this setting can eliminate the need for staff to manually adjust the state of pressing the fuel gun rack 4. That is, when the fuel gun is hung, since the pressure sensor is squeezed by the fuel gun, this alarm device is activated.

[0023] The working principle of the above-mentioned fuel tank cap placement alarm device is as follows:

[0024] First, in the case of refueling required, the staff picks up the fuel gun, and this fuel tank cap placement alarm device does not start. The staff places the fuel tank cap on the internal placement groove 3. After refueling is completed, the staff hangs the fuel gun on the fuel gun rack 4. At this time, the closed circuit of the fuel dispenser gun hanging closed circuit module sends a closed signal; the optocoupler switch amplification module receives the closed signal of the fuel dispenser gun hanging closed circuit module and amplifies it. This module is mainly used to enhance the signal strength and increase the conduction current of the power supply voltage; the photoelectric induction switch module continuously detects the state of the fuel tank cap; when the power is turned on after hanging the gun and the fuel tank cap is forgotten to be taken away, the induction switch module senses an object, and the signal of the induction switch module triggers the timing of the delay relay module. The delay relay module sets a predetermined time period; it can be set to send a signal after five seconds. During the delay time period, the delay relay module maintains the closed state and waits for the signal of the induction switch module to recover; if the signal of the induction switch module has not recovered at the end of the delay time period, the delay relay module triggers an alarm signal; the alarm signal will trigger the audio broadcast module to play the pre-recorded alarm voice to give a warning to the staff or the vehicle owner. The relay is set with double delays. If the fuel tank cap is not taken away within five seconds (the time can be set), an alarm is triggered. After the alarm, it stops, and after waiting for five seconds, the alarm is triggered again until the fuel tank cap is taken away. The sensor (the sensor can be replaced and is not necessarily optoelectronic) cannot sense the object signal and the signal is interrupted, and the fuel tank cap placement alarm device is open-circuited.
