A time-sharing automatic water sample collector

Abstract

The present invention discloses a time-sharing automatic water sample collection device, and belongs to water environment monitoring equipment. The time-sharing automatic water sample collection device comprises a water distribution system (a round disc, iron rods, a bottom disc, a water receiving funnel, a diversion pipe, water sample bottles and a tray), a power system (a rotation wheel and a rubber band), a transmission system (a threaded rod and a ball bearing) and a rotation control system (a cross beam, socket screws, screws, support columns, an escapement fork, a permanent magnet, an electromagnet and a stop rod). According to the present invention, the rotation wheel is pulled to rotate by using the rubber band, the water distribution system is driven to rotate through the transmission system, and the escapement fork is driven to rotate by using the suction and the repulsion between the electromagnet and the permanent magnet in the cases of power on and power off so as to control the rotation amplitude of the water distribution system; with the time-sharing automatic water sample collection device, the rain or river water in different periods can be separately collected into different water sample bottles so as to conveniently research the rainfall runoff process, the rotation driving force is provided by using the rubber band so as to provide the low power consumption, and the water pipe flushing function can be achieved so as to easily improve the water sample collection accuracy.

Description

technical field [0001] The invention belongs to the field of water environment monitoring equipment, in particular to a time-sharing automatic water sample collector used in hydrological testing. Background technique [0002] Since the reform and opening up, my country's society, economy, and people's living standards have developed rapidly, but at the same time, environmental pollution, especially water pollution, has become increasingly serious and has become the focus of attention in today's society. Vigorously strengthening water environment monitoring and protection has been put on the national development agenda. However, due to the high cost of monitoring, the current spatial scope and time intensity of water environment monitoring in my country are insufficient. Therefore, the present invention designs and develops water environment monitoring water sample collection equipment from the perspective of reducing monitoring cost and ensuring monitoring quality.

AI Technical Summary

Problems solved by technology

The (rotation) control system mostly uses electronic control methods, such as stepping motors, and torsion bar switches used by Cao Jiansheng, etc. However, these methods are difficult to effectively and accurately control the rotation range of the water distribution system

Most power systems use electric motors, but electric motors not only consume electricity, but also are difficult to control the speed and rotation angle

At the same time, almost all existing equipment on the market lacks a flushing function, which will cause the liquid remaining in the pipeline to pollute the water sample in the later stage, making it difficult to ensure the sampling accuracy, and its overly complicated design and high price make it difficult to popularize and use it on a large scale
