Water sample collector for discharge port and rain sewage well and water sample sampling method of water sample collector

Abstract

The invention provides a water sample collector for a discharge port and a rain sewage well and a water sample sampling method of the water sample collector, and belongs to the technical field of water sample collection equipment. The problem that water samples at a discharge port and water samples at the bottom of a well are inconvenient to collect by existing water sample collecting equipment is solved. The invention relates to a water sample collector for a discharge port and a rain sewage well. The water sample collector comprises a telescopic assembly, a rotating rod, a collecting assembly and an integration assembly. According to the water sample collector, by adjusting the angle of the collecting assembly, driving the collecting assembly to rotate through the rotating assembly and adjusting through the telescopic assembly, collection of water samples at a discharge port and collection of water samples at the bottom of a well are achieved; In addition, in the water sample collecting process of the water sample collector, the basic water quality parameters of the water sample and the internal condition of the discharge port can be accurately obtained through the integrated assembly, the property and the source of the collected water sample can be preliminarily judged on site, and a reference can be conveniently provided for lab detection of the water sample by people in the later period.

Description

technical field [0001] The invention belongs to the technical field of water sample collection equipment, and relates to a water sample collector used for drain outlets and rainwater wells and a water sample sampling method thereof. Background technique [0002] There is an essential difference between the collection of pipe outlets and rainwater well water samples and surface water samples, which determines that the following problems need to be solved for outlet and rainwater well samplers: [0003] 1. The nature of water samples from outfalls and rainwater wells is more complex and diverse than that of surface water, with many uncertainties. For example, there may be oily, alkaline, acidic and more impurity-rich water samples in outfalls and rainwater wells , during continuous sampling, the sampler body is not easy to clean or it is difficult to achieve a comprehensive cleaning under outdoor conditions, which will affect the water quality of subsequent water samples.

Problems solved by technology

[0003] 1. The nature of water samples from outfalls and rainwater wells is more complex and diverse than that of surface water, with many uncertainties. For example, there may be oily, alkaline, acidic and more impurity-rich water samples in outfalls and rainwater wells , during continuous sampling, the sampler body is not easy to clean or it is difficult to achieve a comprehensive cleaning under outdoor conditions, which will affect the water quality of subsequent water samples

At the same time, when collecting water bodies with particulate matter (such as sewage wells, rural domestic sewage treatment terminal rainwater wells, etc.), the particulate matter in the water body will affect the seal of the water quality sampler, making it difficult to collect water samples conduct;

[0004] 2. The water sample collection of the outlet water needs to enter the water from the top down, while the conventional surface water sampler mostly enters the water from the bottom. Therefore, the water sample collector in the prior art cannot be used for the water sample at the outlet collection;

[0005] 3. The depth of the water body of the rainwater well is uncertain. When the rainwater well and the sewage well are not full of pipe flow, the water in the bottom of the well is very shallow, and the water sample collector in the prior art cannot be used for the collection of such water samples;

[0006] 4. When collecting water samples from outfalls and rainwater wells, we often need to pay attention to the internal conditions of the pipe network and some routine pollution indicators of the collected water samples (such as: pH value, conductivity, temperature, turbidity, etc. ), it is helpful for us to make a preliminary judgment on the nature and source of the collected water samples on the spot, but the water sample collectors in the prior art are not equipped with this function and the corresponding equipment
