Detailed Description
Referring to fig. 1 to 4, a portable liquid level display lamp dedicated detection device according to the present embodiment includes a case 2, and the case 2 is provided with an external power plug 7, a lithium battery 8, a push button switch 4, a slide rheostat 5, and a connector. The external power plug 7 charges the lithium battery 8 through a 220V alternating current power supply, the lithium battery 8 outputs a 24V direct current power supply, the push button switch 4 is connected with the anode of the lithium battery 8 and a connector in series, the sliding rheostat is connected with the cathode of the lithium battery and the connector in series, and the connector is connected with the liquid level display lamp 9 to be tested.
In this embodiment, the connectors have two connectors with different specifications. Six-core connector I2 and four-core connector II 3 can be respectively adopted.
In this embodiment, the case 1 is provided with a handle 6.
The detection device according to the present embodiment operates on the following principle: the external power plug 7 is connected with an external 220V alternating current power supply to charge the lithium battery 8, and the lithium battery 8 outputs a 24V direct current power supply to supply power for the two connectors; to the liquid level display lamp of different specifications, use the connector of two kinds of different corresponding specifications to be connected with the liquid level display lamp 9 that waits to detect, slide rheostat 5 establishes ties with the connector, through the size of adjustment slide rheostat 5, liquid level display lamp 9 that awaits measuring also correspondingly lights up, when output 24V high level, all liquid level display lamps all light up, when reducing output voltage, liquid level display lamp goes out in proper order, when output 0V low level, all liquid level display lamps go out.
