Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that human beings must be on duty in the existing water sample collection process, and it is impossible to realize multiple depths of water sample collection in one operation, and to provide a fully automatic water sample collector for layered collection of water samples. The operation can obtain multiple water layer water samples

Embodiment 1

[0023] see Figure 1-Figure 6 , the fully automatic water sample collector used for layered collection of water samples, comprising a bucket mechanism (B), a cam group mechanism (C), a rope mechanism, a bracket mechanism (A) and a control system, is characterized in that: ( 1) the support mechanism (A) is a cylindrical frame, and the water bucket mechanism (B) with n water buckets (17) evenly distributed in the vertical circumferential direction is fixedly installed in it, and n is a natural number equal to or greater than 1; (2 ) on the central axis of the support mechanism (A), fixedly install a cam group mechanism (C) driven by a motor (46) with n cams in series on one shaft; (3) n of the cam group mechanisms (C) The cams are connected to the upper and lower two seal covers (4) of n water buckets (17) in the water harvesting bucket mechanism (B) respectively via the rope system; (4) the control mechanism has n pressure sensors (11) connected through the control circuit The...

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0026] see figure 1, the control system is composed of a pressure sensor (11) and corresponding control circuits and programs; it is characterized in that: before the water collector starts to work, the pressure of each water layer to be collected is input in the control system, and the pressure to be collected is When the water heater enters the water, the pressure sensor continuously scans the pressure value of the water layer and returns the data to the control system. When the difference between the returned value and the set value is less than the set action value, the control system starts to control the motor (46) Rotate, when the return value of the pressure sensor (11) is just equal to the set value, the motor (46) just turns over the effective arc of the cam 1 (34), the first small chuck (26-1) pops up, and the first water layer After the water sample collection ...

Abstract

The invention discloses a fully-automatic water sampler used for layered collection of a water sample. The fully-automatic water sampler mainly comprises a sampled water barrel mechanism, a cam group mechanism, a rope system mechanism, a support mechanism and a control system part. The sampled water barrel mechanism is uniformly distributed on a small support circular ring, and is used for collecting the water sample; the cam mechanism controls movement of a small chuck under the driving of a moor in order to control closure of a water barrel sealing cover; the rope system mechanism plays a role in transmission of the force of the small chuck and amplification of the stroke; the supporting mechanism plays a role in fixed connection of the whole mechanism and hoisting in the working process; and the control system part plays a role in water depth identification and control of the running of the motor. The water sampler can realize control of the movement of a plurality of cams through one motor in order to realize collection of the water sample in different water layers, so the water sampler has the advantages of realization of whole-course fully-automatic working process, no artificial release of a hammer, realization of unattended operation, wide working area, reduction of interference of artificial factors, and realization of water collection of more water layers through conveniently developing the quantity of water collecting barrels and cams.

Description

technical field [0001] The invention relates to a fully automatic water sample collector for layered collection of water samples, which is used for sampling water samples at fixed depths of water bodies such as rivers, lakes and sea water, and belongs to the field of water sample collection. Background technique [0002] With the development of economy and society, environmental pollution is becoming more and more serious, and water resources, as an important resource for human survival, are now seriously polluted by various domestic sewage and industrial wastewater, which not only destroys the ecological environment, but also endangers human health. , environmental governance is imminent. For water quality monitoring, the collection of water samples is an important part. The collection of water samples often needs to collect water samples at different depths in different places, and then determine the quality of the water body. Most of the existing water sample collectors ...
