Description

TECHNICAL FIELD

[0002] In the process of factory environmental impact assessment that may produce harmful substances, wastewater discharge water quality monitoring is an important content of environmental impact assessment. Toxic and harmful substances may be contained in wastewater, which poses a potential threat to the surrounding environment and ecological system. Therefore, the accuracy of wastewater sampling directly affects the reliability of subsequent test data and the scientificity of environmental assessment conclusions. As the first step of water quality testing, the quality of the sampling process determines the credibility of the analysis results, thereby affecting the environmental assessment and compliance of the project. Under this background, the performance and efficiency of the sampling equipment are particularly critical, as they directly affect the ability to accurately and effectively assess the impact of factory wastewater discharge on the environment.

[0003] Traditional water sampling devices usually adopt a piston design, and the operator needs to manually press down the piston to form a negative pressure to suck the water sample into the sampling barrel. Although this method has a certain reliability, manually operating the piston is not only time-consuming and labor-intensive, but also inconvenient to operate, especially when sampling in deep water, which can cause inaccurate sampling depth or unstable manual operation, thereby affecting the representativeness of the water sample. In addition, the traditional piston sampler can only achieve basic sample collection, and cannot achieve synchronous mixing of the liquid during sampling, which means that after sampling is completed, the water sample may appear stratification, especially water samples containing suspended solids, particulate matter or other multiple components, which can easily form an uneven state in the sampling barrel due to factors such as gravity and density difference. This can cause additional secondary stirring after sampling to ensure the uniformity of the sample composition and thus ensure the accuracy of the test results. However, secondary stirring not only increases the additional operation steps, but also prolongs the time cost of the sampling process, reduces the work efficiency, and is difficult to meet the actual needs of frequent and multi-point sampling in the environmental assessment process.

[0039] Working principle: when sampling and testing the wastewater discharged by the factory, first of all, the sampling bucket 2 is thrown into the water area to be sampled through the pull rope 1. As the sampling bucket 2 gradually sinks, when reaching a certain depth, the buoyancy blocks 3 on both sides of the sampling bucket 2 gradually float up under the action of the water buoyancy. Due to the rising of the buoyancy blocks 3, the sealing door 4 is slowly opened, so that water can flow into the bucket through the openings on both sides of the sampling bucket 2. As water continues to enter, the buoyancy plate 9 inside the sampling bucket 2 also gradually floats up, and this process is driven by buoyancy without additional external intervention. In this design, the sealing door 4 is connected to the buoyancy plate 9 through the rope 13 on the fixed pulley 14, when the buoyancy plate 9 floats up, the sealing door 4 gradually moves downward through the traction of the rope 13, until the opening is completely closed, so as to realize automatic sealing and ensure that the water sample will not change due to external water flow interference. After completing the sample collection, the operator again uses the pull rope 1 to take the sampling bucket 2 out of the water. During the process of the sampling bucket 2 rising out of the water, the water flow impacts the impeller 10 in the base 6, pushing the impeller 10 to rotate. The rotation of the impeller 10 drives the stirring plate 12 connected thereto to rotate synchronously, so as to fully stir the sample in the bucket during the lifting process, so as to homogenize the water sample and avoid affecting the representativeness of the sample due to static or stratification during the sampling process. Through this automatic stirring design, the operation steps of secondary stirring after sampling are reduced, and the working efficiency of the sampling process is effectively improved. This design not only reduces the operation difficulty and physical exertion during sampling, but also realizes the dual functions of automatic sampling and sample homogenization treatment through the ingenious buoyancy drive and mechanical linkage. The overall design has high efficiency and simple operation, provides a more convenient and reliable sampling equipment for water quality testers, and greatly improves the working efficiency and data accuracy in monitoring the wastewater discharged by the factory.
