Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
The present embodiment is applied to the utility model in Dutch bio-toxicity automatic monitor, as shown in Figure 1, the utility model automatic monitor constant current speed automatic water-replenishing device comprises: two water tanks, liquid level sensor, electrically-controlled valve and control modules 6, wherein two water tanks are respectively the first reference water tank 1 and the second reference water tank 2, the bottom level of the first reference water tank 1, higher than the high liquid level (HLL) of the second reference water tank 2, is communicated with by water lines between two water tanks; Liquid level sensor is located on the second reference water tank 2; Electrically-controlled valve is located between the first reference water tank 1 and the second reference water tank 2; The signal wire of liquid level sensor is connected to the input end of control module 6, and electrically-controlled valve is connected with the output signal of control module 6.
As shown in Figure 3, control module 6 has main control module, signal acquisition module, signal output module and power module, and wherein, the control signal of main control module is connected to signal acquisition module and signal output module; Signal acquisition module is connected to the collection signal of liquid level sensor transmission; The control signal of signal output module output is connected with electrically-controlled valve; Power module is connected with the working power of main control module, signal acquisition module, signal output module, liquid level sensor and electrically-controlled valve.
In the present embodiment, liquid level sensor is two optoelectronic switches, is located at respectively high water stage and the low-water level of the second reference water tank 2; Electrically-controlled valve is solenoid valve 5.
