Technical Field

[0002] A river organophosphorus residue sampling and detection device is a device used to collect and detect organophosphorus residues in river water. Its main function is to collect samples from the water body and transmit them to the detection instrument for analysis through a specific sampling mechanism. This device has a wide range of applications in the fields of environmental monitoring and water quality management, and can help monitor whether there are organophosphorus pollutants in river water to protect the safety and sustainability of water resources. It helps to monitor river water quality in real time, detect potential environmental problems early, and provide scientific data support for environmental protection. The design and application of this device helps to maintain the health of the river ecosystem and ensure the safety of humans and the ecological environment.
[0003] At present, there are some limitations in the existing detection devices for organophosphorus residues in rivers. For example, it is impossible to conduct free-flowing random sampling in river water bodies, and it is difficult to effectively filter out impurities in the water. These problems have led to some challenges in the detection of organophosphorus residues in river water bodies. First, the organophosphorus residues in river water bodies are unevenly distributed, so it is difficult to truly reflect the pollution situation using traditional fixed-point sampling methods, which may introduce deviations; secondly, impurities such as suspended matter and algae in the water will interfere with the detection results, reducing the accuracy and credibility of the detection. In order to solve these technical problems, we proposed a sampling and detection device for organophosphorus residues in rivers. Utility Model Content
[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.
[0005] Therefore, the purpose of the utility model is to provide a river organophosphorus residue sampling and detection device, which can solve the technical problems that the existing river sampling and detection devices cannot achieve free flow, random sampling and effective impurity filtration.
[0006] In order to solve the above technical problems, the utility model provides a sampling and detection device for organic phosphorus residues in rivers, which adopts the following technical solutions: comprising a suspension component and a sealing component, the sealing component is installed on the top of the suspension component, the suspension component comprises a suspension barrel body, a water storage liner is installed inside the suspension barrel body, and a gravity center sphere is also connected to the bottom of the suspension barrel body;
[0007] The sealing assembly comprises a suspension cover plate, and a detection component for detecting organophosphorus residues is installed on the top of the suspension cover plate.
[0008] By adopting the above technical scheme, the sampling and detection device designed in this scheme mainly consists of two parts: a suspension component and a sealing component, wherein the suspension component includes a suspension barrel, a water storage liner and a center of gravity sphere. The center of gravity sphere installed at the bottom of the suspension barrel and two sets of buoyancy rings connected to the outside of the suspension barrel can effectively increase the buoyancy of the sampling and detection device as a whole in the water, and at the same time help to keep the sampling and detection device stably suspended in the water, and avoid the sampling and detection device from capsizing during the floating process in the river water; by installing a two-way pump in the middle of the vacuum cavity, river water can be pumped into the water storage liner installed inside the suspension barrel, and the detected water sample can also be discharged from the inside of the water storage liner to the outside; by installing a detection head element at the bottom of the connecting screw, the detection head element can detect and analyze the river water pumped into the water storage liner for organic phosphorus residues;

At the same time, the structural design of the sampling and detection device enables convenient disassembly and maintenance of the various components, thereby improving the overall maintainability of the device. Through this device, we can more accurately and efficiently collect and detect organic phosphorus residues in river water, providing strong technical support for environmental protection. At the same time, its stable transmission and efficient filtration design have also solved the technical problems existing in existing devices to a certain extent, providing a reliable tool for river water quality monitoring.

This design ensures that the filter screen is firmly connected to the suspension barrel body, while allowing the filter screen to be easily disassembled and replaced when necessary. The filter screen can be easily disassembled and cleaned, which is helpful for maintenance and maintenance of the device. Regular cleaning of the filter screen can ensure that it always maintains efficient filtering performance and will not block or reduce the speed of water flow.
