Drawer type portable slope runoff sampler and sampling method thereof

Abstract

The invention relates to a drawer type portable slope runoff sampler and a sampling method thereof. The sampler consists of a water storage device and a collection device, wherein the water storage device comprises a water tank and a stirrer; a flow sensor is arranged at a water inlet of the water tank; the collection device comprises a box seat and a box cover; a distribution pipe valve group in sliding fit is arranged on an electric lead screw guide rail in the box cover; drawers in which multiple rows of built-in sampling bottles are arranged are arranged in the box seat; a row of water injection nozzles of the distribution pipe valve group is aligned with openings of any row of sampling bottles in the drawers; the water tank is connected to a peristaltic pump through a guide tube; the peristaltic pump is connected to the distribution pipe valve group through the guide tube; the flow sensor, a stirring motor of the stirrer, a driving motor of the electric lead screw guide rail, the distribution pipe valve group and a driving motor of the peristaltic pump are electrically connected to a control device. According to the sampler, effects of saving manual labor, conveniently collecting and monitoring in real time are achieved, the water sample collection reliability and accuracy are guaranteed, and the water quality conditions are conveniently and accurately judged.

Description

technical field [0001] The invention relates to a drawer-type portable slope runoff sampler and a sampling method thereof, belonging to the technical field of slope runoff sampling. Background technique [0002] At present, most areas in China mainly use manual sampling for slope runoff sampling, which has poor working conditions, low efficiency, and large errors. It is impossible to record the water volume and speed of slope runoff in real time. Although some companies at home and abroad have launched some water quality samplers, the existing water quality samplers cannot meet the sampling requirements of slope runoff, and are generally heavy and difficult to carry, high manufacturing costs, single sampling mode, and built-in sampling bottles. Convenient extraction and placement and other disadvantages. Most of the samplers use a peristaltic pump connected to the rotary head for water supply, and they have some tightness and corrosion problems. In addition, the existing c...

Problems solved by technology

[0002] At present, the sampling of slope runoff in most areas of China mainly adopts manual manual sampling, the working conditions are poor, the efficiency is low, and the error is large, and it is impossible to record the water volume and speed of slope runoff in real time.

Although some companies at home and abroad have launched some water quality samplers, the existing water quality samplers cannot meet the sampling requirements of slope runoff, and are generally heavy and difficult to carry, high manufacturing costs, single sampling mode, and built-in sampling bottles. Disadvantages such as easy extraction and placement

Most of the samplers use a peristaltic pump connected to the swivel head for water supply, they have some tightness issues and corrosion issues

In addition, the existing collector only has the collection part, which has a single function and is not suitable for intelligent sampling
