Description

Automatic disc type sampler

Technical Field

The utility model relates to a hydraulic engineering technical field, concretely relates to automatic disc type sampler.

Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in the nature to achieve the purposes of removing harmful substances and benefiting benefits, and is also called water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims.

In order to fully develop hydraulic resources and facilitate life of people, river water is often used, the quality of the river water directly influences the quality of life of urban residents, so that the water quality condition of the river water needs to be mastered in real time, and the river water needs to be sampled and detected in order to master the water quality condition of the river water in real time. At present, in the field sampling process, sampling personnel need to stand on a drainage pipeline extending out of a river bank for sampling, under the condition, safety accidents are easy to occur to the sampling personnel, and meanwhile, the sampling sample is easy to be polluted to influence the detection result. In actual sampling, a sampling barrel is often connected with a soft rope, but the mode has many defects and potential safety hazards. The sampling barrel is in flexible connection with the rope and is only suitable for sampling in the vertical direction, when an offshore drainage pipeline is sampled, a sampling person can only stand on the offshore pipeline for sampling, the barrel body is instantly filled with water flow due to large drainage flow of the pipeline, and the impact of water generates great downward pull force on the water barrel, so that the gravity center of the person is passively deviated, the safety of the sampling person is seriously threatened, and the sampling person can fall into a river in serious cases; the water flow impact force enables the rope to slide downwards quickly, the rope and the hand rub to generate high temperature, and the palm of a sampling person is easily burnt and abraded; the sampling barrel body is pulled right above the rope, water drops on the rope fall into the sampling barrel, and a water sample is easily polluted, so that the accuracy and the reliability of detection are reduced; especially, when the microorganism index is detected and sampled, the microorganism pollution is possibly brought in the process of transferring the sample barrel to the sterile bottle, and the detection result is deviated.

Through retrieval, the Chinese utility model with application number 2017207305885 discloses an automatic sample injector, which comprises a base, a first automatic lifting rod arranged on the left side of the upper part of the base, a cross arm arranged on the upper part of the first automatic lifting rod, a sample injection needle arranged at the end part of the cross arm, and a sample bearing mechanism arranged on the upper part of the base; the sample bearing mechanism comprises a bearing table arranged on the upper portion of a base through a slewing bearing, a rotating shaft is arranged at the bottom of the bearing table, the lower end of the rotating shaft is connected with the output end of a driving motor, the driving motor is located in a groove formed in the base, a stepped groove with a T-shaped cross section is formed in the center of the upper surface of the bearing table, an annular strong magnet is embedded in the shoulder of the stepped groove, a sample disc matched with the stepped groove is arranged in the stepped groove, and an annular iron sheet matched with the strong magnet is arranged at the bottom of the sample disc.
