Description

Water quality monitoring water tank

Technical field

This utility model is related to water quality monitoring water tank.

Background technology

In order to detect reservoir and river water quality index in river basin, need to be in the diverse location in stack room and river course and difference depth Degree collection water sample, usual way is that device for fetching water is placed in the sampling of sampled point water intaking under water using rope by manpower；At present, water sample is adopted Storage mostly is the tubular construction of closing, and its bottom surface and top surface are equipped with flat one-way check turnover panel, or cylinder underseal closes cover and sets Have versions such as board-like check turnover panel, during device for fetching water decentralization, (or leaning on rope power) opens up turnover panel all automatically, water fill after on Extract hydrophone, turnover panel is automatically switched off, until leaving the water；These device for fetching water are because water inlet structure design is preferable not to the utmost, sealing Can be poor, so these device for fetching water are difficult to the water body avoiding institute's water sampling will not mix other different layers positions, cause water sample not reach Monitoring accuracy, increases difficulty to monitoring.

Utility model content

This utility model aims to solve the problem that the problems referred to above, there is provided water quality monitoring water tank, and it is by setting to each spring Different deformation quantities, and then control the different levels of water intaking water sample；When this water quality monitoring water tank is transferred to water, with depth Intensification, spring compression in the presence of hydraulic pressure, stop part promotes connecting rod and sealing ring to move upwards in the presence of hydraulic pressure Dynamic, water enters accommodating intracavity by through hole, and when accommodating intracavity is full of by water sample, stop part is contacted with connection lid bottom just When, cavity of resorption is closed, the water intaking end-of-job of this water layer；The technical scheme that it adopts is as follows：

Water quality monitoring water tank, including casing, connection lid and balancing weight, described box house cavity is divided into several simultaneously The containing cavity of row's arrangement, each containing cavity joins to fit case lid, and case lid is threadedly connected on casing；Described case lid is provided with water flowing Hole, described connection lid is threadedly connected at the limbers of case lid, described connection lid include exterior circular column, inner cylinder, sealing ring, Connecting rod and spring, are provided with horizontal dividing plate in described inner cylinder, and the internal cavities of inner cylinder by dividing plate be divided into epicoele and Cavity of resorption；Described dividing plate is provided with the through hole for connecting epicoele and cavity of resorption, and described connecting rod is threaded onto in the through hole of dividing plate, described close Seal is fixed in connecting rod top, and sealing ring overlapping edges are in inner cylinder top；Described spring is set on connecting rod, and is located at Lower intracavity, described connecting rod end is formed with stop part, the diameter with diameter greater than cavity of resorption of described stop part, described balancing weight dismounting It is connected on casing lateral wall.

On the basis of technique scheme, also include drainage mouth, described drainage mouth be internally formed for by connecting rod to The cylinder of upper jack-up, described drainage mouth top is provided with hook, described connection lid bottom outside wall is formed with and matches with hook Link.

On the basis of technique scheme, also include drainage screen, it is arranged at accommodating intracavity.

This utility model has the advantage that：By different deformation quantities are set to each spring, and then control water intaking water The different levels of sample；When this water quality monitoring water tank is transferred to water, with the intensification of depth, spring is pressed in the presence of hydraulic pressure Compression deformation, stop part promotes connecting rod and sealing ring to move up in the presence of hydraulic pressure, and water enters accommodating intracavity by through hole, when When accommodating intracavity is full of by water sample, when stop part is contacted with connection lid bottom just, cavity of resorption is closed, the water intaking work of this water layer Terminate；When needing part water sample to be detected, drainage can be played by drainage mouth, only need to by its cylinder by stop part to Upper jack-up；By balancing weight, water quality monitoring water tank is transferred to required water layer；By drainage screen, water sample is entered Row filters, and prevents excessive pasture and water and algae from adding heavily to the difficulty of the work, and affects accuracy of detection；Total is simple, easy to use, real Strong with property.
