Domestic drinking water full-automatic sampler

Abstract

The invention relates to the technical field of drinking water sampling, in particular to a domestic drinking water full-automatic sampler which comprises a sampling box body, an upper mounting plateis arranged at the top of the sampling box body, a lower mounting plate is arranged at the bottom of the sampling box body, a plurality of screw rods are fixedly connected to the upper mounting plate,uncovering mechanisms are fixedly connected to the screw rods, a top plate is arranged at the tops of the uncovering mechanisms, and a plate is further arranged on the uncovering mechanisms. The PLCis arranged to control the first forward and reverse rotation motor and the second forward and reverse rotation motor, lifting and rotation of the uncovering buckle are achieved, the water outlet amount of the electromagnetic valve is arranged on the sampling water injection pipe, the driving mechanism is controlled to drive the sampling container to move, full-automatic sampling is achieved, timeand labor consumed by manual sampling are avoided, practicability is high, and sampling efficiency is high; and the toothed bar is arranged in the second linear bearing, so that the toothed bar drives the first bearing plate to lift vertically, the stability is good, and the uncovering buckle can be buckled on the sampling container more accurately.

Description

technical field [0001] The invention relates to the technical field of drinking water sampling, in particular to an automatic sampler for drinking water. Background technique [0002] Drinking water refers to water that can be directly supplied to the human body for drinking without treatment. Water is the main component of body fluid, and is an important substance that constitutes cells, tissue fluid, plasma, etc. As the medium of all chemical reactions in the body, water is a platform for the transportation of various nutrients and substances. Sampling devices are required for drinking water collection when testing drinking water. Drinking water is closely related to people's lives. Drinking water needs to be sampled and tested frequently to ensure the water quality for residents to drink. [0003] Most of the existing drinking water samplers are manually sampled by the staff, which is not only time-consuming and labor-intensive, but also the storage time of the sampler...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing drinking water samplers are manually sampled by the staff, which is not only time-consuming and labor-intensive, but also the storage time of the sampler after sampling is limited, and it should not be stored for too long; and the existing sampler is in the sampling process, due to The requirements for different water quality are different, and it is impossible to realize the disinfection treatment, and it is easy to cause secondary pollution during the sampling process, which has certain limitations. The existing sampler has poor stability during use and often requires manual adjustment.
