Abstract

The utility model relates to a flowing water sample field, specific spot sampling robot for water quality testing that says so, including base member and outer support, outer support and sewage flow through the passageway and be connected mutually, the outer support is used for fixing this device, the base member be connected with the outer support, and be connected through interference fit between base member and the base member, the sample requires the decision to base member installation quantity according to sewage, the base member of this device can be dismantled, when having relatively high expectations to the area detection that waits to take a sample, when the flat rate of sample is great the quantity of base member need relatively more, otherwise the quantity of base member is less. The utility model discloses can the not timing, what need not to prepare takes a sample to sewage, can realize the periodic sampling test to sewage, also can carry out the sample of irregular ambiguity to sewage, can detect the sewage discharge situation of sewage discharge unit constantly, just the utility model discloses a collection system inner structure is simple, and it is effectual to absorb water.

Description

A kind of water quality detection spot sampling robot

Technical field

This utility model relates to the flowing water sampling field of hydraulic engineering, a kind of water quality detection spot sampling robot.

Background technology

At present, along with the high development of industry degree, sewage discharge phenomenon remains incessant after repeated prohibition, for most of production enterprises, Sewage discharge is inevitable, these relevant departments of China has put into effect relevant policy and has carried out enterprise's sewage discharge restriction, but Effect always can not reach perfect condition, and weighing apparatus multiple enterprises overtly agrees but covertly oppose, and ecological balance is brought serious by a large amount of sewage effluents Harm, on the other hand, sewage carries out detection sampling when, is mostly artificial variable interval sampling, when can frequently result in sampling Normally, people leaves the phenomenon appearance that after stain continues.

Sewage sampling is also occurred in that relevant detection device, the China of Application No. ZL201310533736.0 by prior art Patent discloses a kind of batch (-type) sewage automatic sampling device, but it be timing sampling in work process again, for sewage discharge enterprise For industry, the rule of sewage discharge still can be had to follow, the effect for sewage discharge detection sampling is not the most fairly obvious.

The Chinese patent of Application No. 201520844805.4 discloses a kind of for mobility sewage batch (-type) sampler, its The sampling detection of the periodicity to sewage can be realized, it is possible to sewage is carried out irregular ambiguity sampling, it is possible to moment detection sewage The sewage discharge situation of discharge unit；But, this described harvester include housing, upper supporting column seat, pillar, piston plate, Vertical support, connecting rod, horizontal seat, No. two connecting rods, No. three connecting rods, stopper, lower supporting rod seat and fixing seben, pass through Under the effect of the transmission of connecting rod, inlet opening is blocked by stopper；Said structure has open defect, because existing sample acquisitions device Volume is the least, installs so many bar linkage structure, extremely wastes time and energy, increase connecting rod in the harvester of small size Manufacture and the installation difficulty of personnel, simultaneously as this harvester is internally installed multiple connecting rod, connecting rod rotate appearance for a long time Easily causing the instability of structure, consequently, it is possible to cause connecting rod cracking and cannot work, enabling to gather dress so being now badly in need of one Put the relatively simple firm sewage sample collection equipment of internal structure.

Summary of the invention

For the problems of the prior art, this utility model provides a kind of water quality detection spot sampling robot, and it can not Regularly, it is not necessary to preparation sewage is sampled, the sampling detection of the periodicity to sewage can be realized, it is possible to sewage is carried out nothing The ambiguity sampling of rule, it is possible to the sewage discharge situation of moment detection sewage discharge unit, is conducive to combining sewage discharge Conjunction manages, and this utility model internal structure is relatively simple simultaneously, practical, and sewage is easily accessible collection of the present utility model In device.

This utility model solves its technical problem and be the technical scheme is that a kind of water quality detection spot sampling robot, bag Including matrix and support arm, described support arm flows through passage with sewage and is connected mutually, and support arm is for being fixed this device；Institute The matrix stated is connected with support arm, and is connected by interference fit between matrix with matrix, and matrix installs quantity according to sewage Sampling requirement determines, the matrix of this device can be dismantled, and when requiring higher for region detection to be sampled, samples flat rate bigger The quantity of Shi Jiti needs more relatively, otherwise, the negligible amounts of matrix.
