The pressure plate 3 and the support table 4 are in a vertical plane. The detection circuit comprises adjustable resistors RP1 and RP, voltmeters V1 and V and a pair of photovoltaic resistors RL which are connected through circuit board wiring, wherein one end of the pair of photovoltaic resistors RL is connected with one end of the first adjustable resistor RP and the positive power supply input end of the first voltmeter V, one end of the second adjustable resistor RP1 and the positive power supply input end of the second voltmeter V1 are connected, the other ends of the two adjustable resistors RP1 and RP are connected with the negative power supply input ends of the two voltmeters V and V1, the pair of photovoltaic resistors VL (and the detected photovoltaic resistors have the same specification, and when the photovoltaic resistors with different types are measured in batches, the pair of photovoltaic resistors VL with the same type are selected to be singly arranged at the left lower end in the shell 1 and the light receiving surface faces upwards.
As shown in fig. 1 and 2, the power input terminals 1 and 2 pins of the power module A1 and the power input terminals 1 and 2 frames of the voltage regulator A2 are respectively connected with two poles of an ac 220V power supply through wires. The power output end of the power module A1, the power input ends 1 and 2 pins of the 3-pin and 4-pin power switch S and the power input end of the detection circuit are respectively connected with the other end of the photovoltaic resistor RL and the other end of the adjustable resistor RP through wires.

The novel portable electric power generating device is shown in figures 1 and 2, and is simple and compact in structure, convenient to carry and low in cost.

Before a worker detects a corresponding photovoltaic resistor RL1, the movable door 5 is opened, then the worker respectively places two pins (holding the front ends of the photoresistors) of the photovoltaic resistor RL1 on the supporting table 4 (the two pins are positioned on the two metal sheets T), then the worker dials the handle of the power switch S leftwards, the 1 pin, the 2 pin, the 3 pin and the 4 pin of the power switch S (the handle is positioned outside the open hole at the front end of the element box) are respectively communicated, thus, the movable column of the positive pole and the negative pole of the electric telescopic rod M is powered by the power input ends to push the pressing plate 3 to move downwards, and after the pressing plate 3 effectively presses the two pins of the photovoltaic resistor RL1, the power switch is closed (the lower ends of the pins are in contact with the metal sheets T, and the two pins of the photovoltaic resistor RL1 are respectively communicated with one end of the adjustable resistor RP1 and the other end of the photoresistor RL). Then, the worker closes the movable door 5 (the movable door is attached to the front end of the housing by magnet attraction). During testing, a worker manually adjusts the handle of the voltage regulator A2 to adjust the voltage output by the voltage regulator A2, so that the voltage input into the illuminating lamp B changes, the intensity of the electric light emitted by the illuminating lamp B is different, the intensity of the light irradiated on the light receiving surface of the photovoltaic resistor R1L and the light receiving surface of the photovoltaic resistor RL also changes, the resistance values of the light Fu Dianzu RL1 and the photovoltaic resistor RL change, and the resistance value is relatively large when the light is high, and is relatively small when the light is high.

By observing the voltage data of the two voltmeters V1 and V, the staff can observe that the values displayed by the voltmeters V1 and V are close, and the quality of the detected photovoltaic resistor RL1 is relatively good (on the basis of ensuring that the quality of the detected photovoltaic resistor RL is good). When the voltage gauges V1 and V show a difference in value, this represents a relatively poor quality of the photovoltaic resistor RL1 to be detected. After detection, a worker opens the movable door 5 and then dials the handle of the power switch S rightwards, and the pins 1, 2, 5 and 6 of the power switch S are respectively communicated, so that the movable column of the power input end of the negative electrode and the positive electrode of the electric telescopic rod M is electrified to drive the pressing plate 3 to move upwards, and when the distance between the pressing plate 3 and the two pins of the photovoltaic resistor RL1 is kept, the power switch is closed to take out the light Fu Dianzu RL1 to be detected, and all detection flows are completed.
