At present, the existing device that keeps sample that exceeds standard on the market all uses keeping sample or discharge of battery valve control sample, has the short and material pollution problems of failure rate height, life-span of battery valve like this, and the system that forms complexity comparatively.A kind of " sampling thief that keeps sample exceeds standard " disclosed in the prior art, publication number is: CN201138305, open day be: the Chinese patent of 2008.10.22, its unique point is: comprise housing, low temperature is preserved case and sampling bottle, described sampling bottle is positioned at low temperature and preserves case, the described storage sample overflow device that sampling thief also comprises and analysis water-like is gathered synchronously that keeps sample that exceeds standard, sampling pump and PLC controller, described storage sample overflow device is communicated with sampling bottle by pipeline, be provided with sampling pump at described pipeline, porch at described sampling bottle is provided with Controlled valve, connect evacuated tube at described pipeline, described evacuated tube is provided with exhaust-valve; The starting switch of described sampling pump, Controlled valve and exhaust-valve are connected with the PLC controller, described PLC controller comprises be used to after receiving analysis result, start the starting switch of sampling pump, as being the signal that exceeds standard, open Controlled valve simultaneously, as be normal signal, open the control module that keeps sample that exceeds standard of exhaust-valve simultaneously.This invention provides a kind of efficient high sampling thief that keeps sample that exceeds standard that keeps sample, keeps sample that links, starts with analytical instrument or supervisory system when analysis result exceeds standard.
A kind of " water sample on-line monitoring and overproof sample holding apparatus and method of operating thereof " also disclosed in the prior art, publication number is: CN101493471, open day be: the Chinese patent of 2009.07.29, this device comprises programmable controller (55), PH meter (52), equal proportion sampling instrument (51), determining instrument, water sample water inlet pipe (41) and water sample rising pipe (42), it is characterized in that, PH in parallel pond (31) and the multiparameter pond (32) that keeps sample that keeps sample is set between water sample water inlet pipe (41) and water sample rising pipe (42); PH meter detection probe is connected to the PH pond that keeps sample, and the detection probe of determining instrument is connected to the multiparameter pond that keeps sample.Wherein, water sample water inlet pipe (41) is connected to the PH pond (31) that keeps sample by water-supply-pipe (43), and water-supply-pipe upper edge water (flow) direction sets gradually solenoid valve (11) and water pump (21); Multiparameter keeps sample and is connected with drainpipe (45) between pond and the water sample rising pipe, and drainpipe is provided with solenoid valve (12).This invention can realize the real-time PH of water sample simultaneously and monitoring and the operation that keeps sample that exceeds standard of other parameters in certain mensuration cycle are arranged, the water sample of gathering that exceeds standard does not have the time difference, the accuracy height has real-time water sample representativeness, the operation that keeps sample of carrying out continuously, monitor accurately and exceed standard.
All there be keeping sample of battery valve control sample in above-mentioned two inventions or discharge, and have the short and material pollution problems of failure rate height, life-span of battery valve like this; And system architecture complexity.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of online device that keeps sample that exceeds standard, and the influence of having avoided the reason of battery valve to bring reduces the dustiness of the sample that exceeds standard.
The present invention is achieved in that a kind of online device that keeps sample that exceeds standard, and comprises logic controller, the pond that keeps sample, first sampling pipe, second sampling pipe, first sampling pump, second sampling pump, three-way connector and sampling bottle; Described logic controller is connected with second sampling pump with described first sampling pump respectively; Described first sampling pump is connected with first port of described three-way connector through described first sampling pipe; Second port of described three-way connector is connected with described sampling bottle; The 3rd port of described three-way connector is connected with described second sampling pump through described second sampling pipe; Described second sampling pump is connected with the described pond that keeps sample.
Further, described three-way connector is T-valve or three-way pipe.
Further, also comprise one for the rotten low temperature preservation case of the water sample that prevents from gathering, described sampling bottle places described low temperature to preserve case.
Further, described low temperature preservation case is refrigerator-freezer or refrigerator.
The invention has the advantages that: the present invention includes logic controller, the pond that keeps sample, first sampling pipe, second sampling pipe, first sampling pump, second sampling pump, three-way connector and sampling bottle; Logic controller is controlled first sampling pump and the second sampling pump work; First sampling pump extracts water from river after, by second sampling pump water sample that extracts is placed in the pond that keeps sample; By Water Test Kits water sample is carried out data analysis and judge whether water sample exceeds standard, and is, then control will keep sample water in the pond of second sampling pump by logic controller and extract and be discharged in the sampling bottle, to preserve sample; Not, then logic controller is controlled first sampling pump and second sampling pump rotates simultaneously, water sample is extracted be discharged in the river.The present invention does not use battery valve, directly operates by pump, and the influence of having avoided the reason of battery valve to bring reduces the dustiness of the sample that exceeds standard, and of the present invention simple in structure, easy to operate.
