[0021] Embodiment 1

[0022] See also Figure 1-5 , an alarm device for preventing a power supply vehicle from being pulled or hung, comprising a dump sensor 70, a buzzer alarm 60, and a closed proximity switch 40,

[0023] The tipping sensor 70 is fixedly connected to the cable connector, and the tipping sensor is linearly connected to the cigarette lighter interface end 100 in the cab 10 of the power supply vehicle through the connecting wire, and the power supply for the tipping sensor 70 is provided through the cigarette lighter;

[0024] The buzzer alarm 60 is fixedly connected to the center console 50 in the cab 10 of the power supply vehicle. The buzzer alarm 60 is also linearly connected to the cigarette lighter interface 100 in the cab 10 of the power supply vehicle through a connecting wire, and the power supply for the buzzer alarm 60 is provided through the cigarette lighter.

[0025] The closed proximity switch 40 is composed of contacts of the closed proximity switch and contacts of the closed proximity switch; the contacts of the closed proximity switch are fixedly connected to the ventilation cover plate of the power supply vehicle, and the contacts of the closed proximity switch are fixedly connected to the dust protection cover 90 of the power supply vehicle, and the contacts of the closed proximity switch are in contact with the contacts of the closed proximity switch; the contacts of the closed proximity switch are also linearly connected to the cigarette lighter interface terminal 100 in the cab 10 of the power supply vehicle through connecting wires, and the power for the closed proximity switch 40 to work is provided by the cigarette lighter.

[0026] Since the cigarette lighter voltage is 24V, a DC transformer needs to be installed between the tipping sensor 70 and the cigarette lighter interface terminal 100 to convert the required voltage into 12V to enable the tipping sensor 70 to work normally.

[0027] In order to extend the service life of the tipping sensor 70 and the closed proximity switch 40, a travel limit switch 30 is installed at the handbrake 20 of the cab 10 of the power supply vehicle to control the on and off of the tipping sensor 70 and the closed proximity switch 40. The travel limit switch 30 is also linearly connected to the cigarette lighter interface end 100 through a connecting wire.

[0028] The travel limit switch 30 serves as a master control switch, and determines whether the alarm device is powered on by the state of the handbrake 20 (because the state of the handbrake 20 generally determines whether the power supply vehicle is to move or stop).

[0029] The cigarette lighter interface end 100 is also linearly connected to the controller 80 via connecting wires. The controller 80 serves as a main control module and is linearly connected to the tipping sensor 70 , the buzzer alarm 60 , the closed proximity switch 40 and the travel limit switch 30 .

[0030] The tipping sensor 70 is used to measure the angle of the cable connector. When the cable connector is plugged into the aircraft in an upright state, if the operator starts the vehicle and releases the handbrake 20, the tipping sensor 70 will give a signal to the controller 80, which will trigger the buzzer alarm 60 to remind the operator in the cab. After the cable connector is unplugged from the aircraft and placed on the vehicle, the cable connector changes to a vertical state, thereby turning off the buzzer alarm 60.

[0031] During the actual operation of the embodiment of the present application, when the power supply vehicle needs to leave the aircraft after the operation is completed, the operator in the cockpit releases the handbrake 20. As the handbrake 20 is lowered, the travel limit switch 30 receives a signal and energizes the tipping sensor 70, the buzzer alarm 60, and the closed proximity switch 40 via the controller 80. If the cable connector is not unplugged from the aircraft (the cable connector is upright on the aircraft at this time), the tipping sensor 70 will transmit a signal to the controller 80, and the buzzer alarm 60 will be operated via the controller 80. At the same time, if the ventilation cover is not closed or not tightly closed, the closed proximity switch contact is separated from the closed proximity switch contact, and its signal is transmitted to the controller 80, and the buzzer alarm 60 is operated via the controller 80, thereby reminding the operator (the cable connector is not unplugged from the aircraft or the ventilation cover is not closed or not tightly closed, any one of which will cause the buzzer alarm to sound).

[0032] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: by adding an alarm device to the power supply vehicle, it can serve as a reminder to the power supply vehicle operator, effectively preventing the risk of scratching or hanging the aircraft shell when the power supply vehicle leaves the aircraft.

[0033] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
