Description

Technical Field

[0001] The utility model relates to the field of water sample extraction devices, in particular to a water quality detection and extraction device for municipal water supply. Background Art

[0002] Municipal water supply is the urban water supply system and an integral part of urban public utilities. Urban water supply systems are usually composed of water sources, water pipelines, water plants and distribution networks. Water sources are divided into source water, travel water and terminal water. Source water is generally rivers, lakes, etc. When sampling water quality, staff are generally required to drive a boat and use a collection and extraction device to collect water samples.

[0003] At present, a Chinese utility model with the announcement number CN219870489U discloses a water quality detection sample extraction device, including a box body, a water storage shell is arranged on the left side of the box body, the right side of the water storage shell penetrates into the inner cavity of the box body, a partition is fixedly connected between the top and the bottom of the inner cavity of the water storage shell, a push rod is arranged on the right side of the partition, the left side of the push rod penetrates the partition and is fixedly connected with a rubber plate, a tension spring is sleeved on the surface of the push rod, a control box is arranged on the right side of the box body, the left side of the control box penetrates into the inner cavity of the box body, and a motor is fixedly connected to the rear side of the inner cavity of the control box. The utility model solves the problem that the existing water quality detection sample extraction device cannot sample sewage of different depths by arranging a water storage shell, a partition, a push rod, a rubber plate, a tension spring, a control box, a motor, a turntable, an adjustment rod, a movable plate, a push block and a spring. The water quality detection sample extraction device has the advantage of being able to extract sewage of different depths.

[0004] To sum up, although the extraction device can achieve the purpose of stratified sampling, there are still certain problems when using it. First, the extraction device is equipped with structures such as motors and batteries. The motors and batteries are used in conjunction with other structures to drive the rubber plate to seal the water inlet of the extraction device. The structure is complex, the production cost is high, and the practicality is poor. At the same time, the extraction device lacks a quantitative measurement structure. When the staff uses a rope to tie the extraction device and put it into the water body for sampling, they cannot know the depth of the extraction device in the water, and the purpose of quantitative depth sampling cannot be achieved. Utility Model Content

[0005] The utility model aims to provide a water quality detection and extraction device for municipal water supply, which has the advantages of strong practicability and fixed-depth sampling.
