Embodiment
Now, describe embodiment of the present utility model in detail in conjunction with Figure of description:
As shown be branch sampling instruments such as branch up-to-date style sewage, rack 19 becomes three zones, upper, middle and lower by last shelf 13, following shelf 18 with space segmentation, rack 19 top area install be provided with microcomputerized controller 11 and with the GPRS module 12 of its circuit control linkage, GPRS module 12 is used for the sampled signal of receiving remote control center.The central region of rack 19 is installed pretreatment unit 8, low temperature chamber 17 is set, pretreatment unit 8 is used for the gas of draining-off sewage, separate the solid waste in the sewage, guarantee to gather the quality of water sample, entrance point is connected with water inlet pipe 1 by water inlet motorized valve 6, be equipped with suction pump 4 on the water inlet pipe 1 before the water inlet motorized valve 6, suction pump 4 places the lower region of rack 19, and water inlet motorized valve 6, suction pump 4 are respectively by relay control interface 7 and microcomputerized controller 11 circuit control linkages; The connection of pretreatment unit 8 bottoms is provided with drainpipe 2, is equipped with water outlet motorized valve 5 on the drainpipe 2, and water outlet motorized valve 5 is by relay control interface 7 and microcomputerized controller 11 circuit control linkages; Be equipped with the level switch 9 with microcomputerized controller 11 circuit control linkages in the pretreatment unit 8, and the run-down pipe 3 that is connected with drainpipe 2; The connection of pretreatment unit 8 endpiece is provided with peristaltic pump 10, peristaltic pump 10 is by relay control interface 7 and microcomputerized controller 11 circuit control linkages, extract the water sample of constant flow rate or flow by constant rotating speed, usually under the condition of constant rotational speed, can obtain required sampling quantity by the working time of setting peristaltic pump 11; Cooperate and obtain the value of water sample the switching time of controlling preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13; Peristaltic pump 10 output terminals are connected with preposition two-position three way motorized valve 14 input ports, and a delivery outlet of preposition two-position three way motorized valve 14 is connected with preposition sampling bottle 16 pipelines, and another delivery outlet is connected with the input port pipeline of rearmounted two-position three way motorized valve 13; A delivery outlet of rearmounted two-position three way motorized valve 13 is connected with rearmounted sampling bottle 15 pipelines, another delivery outlet is connected with pretreatment unit 8 pipelines, and preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13 are respectively by relay control interface 7 and microcomputerized controller 11 circuit control linkages.Preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13 and preposition sampling bottle 16, rearmounted sampling bottle 15 place respectively in the low temperature chamber 17, can keep gathering the sewage sample not because of the deterioration failure of temperature height, guarantee the stability of water sample.Described level switch 9 is a signal triggering device, if still indicate lack of water through one section time of pumping process level switch 9, the expression flow is too small, and this moment, sampling instrument was not sampled, to avoid unreliable sampled result; If be triggered at this section period level switch 9, microcomputerized controller 11 control suction pumps 4 motorized valve 6 that stops, intaking cuts out, represent that sewage sample to be sampled is ready to, startup peristaltic pump 10, preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13 are sampled; Before sampling action was finished, water outlet motorized valve 5 cut out always, opened water outlet motorized valve 3 after each sampling finishes and bled off sewage.
When beginning to sample, at first control peristaltic pump 10 counter-rotatings, remaining on preposition two-position three way motorized valve 14 and preposition sampling bottle 16 connecting lines, and the sewage back suction on rearmounted two-position three way motorized valve 13 and rearmounted sampling bottle 15, pretreatment unit 8 connecting lines is finished the automatic cleaning to pipeline in pretreatment unit 8.Open into water motorized valve 6, start suction pump 4 water samplings in pretreatment unit 8, unnecessary overflows after drainpipe 2 is discharged from run-down pipe 3.If pretreatment unit 8 pretreaters the inside does not reach enough liquid levels, level switch 9 can not be triggered, and samples with regard to not starting peristaltic pump 10, and suction pump 4 and water inlet motorized valve 6 continue to open extraction water sample in pretreatment unit 8.Reach set liquid level, sewage sample and fully mix after, water inlet motorized valve 6 cuts out, suction pump 4 quits work.Level switch 9 is triggered, and starting peristaltic pump 10 is just changeing, and extracts water sample from pretreatment unit 8.Before water sample injects sampling bottle, needing to confirm does not have air in the sampling connecting line, so when peristaltic pump 10 is just changeing, preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13 and preposition sampling bottle 16, the connection outlet of rearmounted sampling bottle 15 is all closed, so just formed from pretreatment unit 8 through peristaltic pump 10, preposition two-position three way motorized valve 14, rearmounted two-position three way motorized valve 13 flows back to the pipeline loop of pretreatment unit 8, water sample flows back to pretreatment unit 8, show in the whole connecting line and no longer include air, in the pipeline cleaning process that begins to sample at every turn, be exactly cleaning to this whole connecting line.Then the outlet that preposition two-position three way motorized valve 14 is connected preposition sampling bottle 16 is communicated with, and finishes sampling to preposition sampling bottle 16 through the operation setting sampling time.Open the outlet of the rearmounted two-position three way motorized valve 13 of preposition two-position three way motorized valve 14 connections, be connected the outlet of rearmounted sampling bottle 15 with rearmounted two-position three way motorized valve 13, inject rearmounted sampling bottle 15, move the identical sampling time and finish sampling rearmounted sampling bottle 15.Rearmounted two-position three way motorized valve 13 is opened the outlet that is connected with pretreatment unit 8, finishes sampling.Because of identical, so the water sample amount of injecting two sampling bottles by peristaltic pump 10 is the same at the time set of preposition sampling bottle 16,15 samplings of rearmounted sampling bottle; Though injecting the action of two sampling bottles is not to carry out simultaneously, but the water sample that injects two sampling bottles all obtains from pretreatment unit 8, and the water sample of pretreatment unit 8 is to come from a time period sampling water body, for once obtaining together and mixing equal, therefore concerning once sampling, the water sample in preposition sampling bottle 16, the rearmounted sampling bottle 15 is identical.After sampling is finished, open water outlet motorized valve 3, the sewage in the pretreatment unit 8 is bled off through drainpipe 2.Sample lines is cleaned in the peristaltic pump counter-rotating again, prepares sampling next time.
