Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented under premised on technical solution of the present invention, gives detailed embodiment, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1 to 4, the microcomputerized control automatic sampling apparatus involved by the present embodiment, is made up of Temporal Sampling electronic control mechanism 1, water distribution mechanism 2, sample storage space 3, automatic sampling pump 4 and 12V accumulator 5; Described Temporal Sampling electronic control mechanism 1 is located at the top in sample storage space 3, and adopt poly (methyl methacrylate) plate to make shell, bosom dividing plate connects up, and connects one to two ten six micro computer time controller 1-1 and to two 16 solenoid valve.Described micro computer time controller 1-1 can enroll one to two ten four group of start-stop time, can set, proofread and displaying time, comprise year, month, day and time, minute, second, period of switching time, opens the cycle, can set every day same time and every day different time.
Described water distribution mechanism 2 is connected by annulus line, at the middle part of automatic sampling apparatus.Arrange one to two ten four water filling port respectively, one to two ten four solenoid valve is arranged on water filling port front end, and solenoid valve is connected to micro computer time controller 1-1 by cable.A described solenoid valve 2-1 controls water inlet, entering water electromagnetic valve 2-2 is the Water filling valve of sampling jar, No. two solenoid valve 2-3 are flowing water Valve, when water inlet solenoid valve 2-1 and water outlet No. two solenoid valve 2-3 opens, entering water electromagnetic valve 2-2 closes, No. two solenoid valve 2-3 are closed after continuum micromeehanics 30s ~ 60s, open the entering water electromagnetic valve 2-2 of corresponding time period, this process completes auto-flushing and sampling automatically.
