Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an environmental monitoring sampling device with filtration and storage functions. Background Technology

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. It involves monitoring and measuring indicators that reflect environmental quality to determine the level of environmental pollution and environmental quality. Environmental monitoring is the foundation for scientific environmental management and environmental law enforcement supervision, and it is also an essential basic task for environmental protection. Environmental monitoring requires quantitative analysis of various pollutants in the environment, and sampling is one of the key steps to ensure the accuracy of the analysis results. Through reasonable sampling methods and operating procedures, accurate and reliable analysis results can be obtained.

[0003] A search revealed a Chinese patent, "Environmental Monitoring Sampling Device with Filtering and Storage Function," which discloses an environmentally friendly gas sampling device for environmental monitoring with filtering and storage function. This patent addresses the shortcomings of existing environmental monitoring gas sampling devices, such as the inhalation of dust and impurities during gas extraction, which can affect monitoring. Furthermore, the inlet cannot be sealed after extraction, leading to leakage and contamination. This patent addresses these issues by allowing the door to be opened and closed for easy cleaning and maintenance. A pipe clamp secures the inlet pipe, preventing it from becoming cluttered or contaminated with dust. A one-way valve opens inwards during intake, allowing the gas to be stored in the storage tank. Simultaneously, the piston compresses downwards, sealing the ventilation passage to prevent backflow.

[0004] The aforementioned environmental monitoring sampling device is convenient for sampling the gas environment. However, when sampling the water environment, such as rivers, it is necessary to use a sampling tube to draw water from the river. River water usually contains a lot of mud, sand, algae, and floating debris. When sampling river water, it is not convenient to filter out large particles of impurities such as algae and tree branches. This can easily cause impurities to enter the sampling tube, leading to blockage and making it difficult to sample. This increases the difficulty of the sampling process and reduces the sampling efficiency. Utility Model Content

[0037] As attached Figure 4 As shown, an underwater motor 13 is fixedly installed on one side of the sampling tube 5. A gear 14 is fixedly connected to the output end of the underwater motor 13. The gear 14 and the gear ring 12 are meshed. A protective shell 15 is fixedly connected to the outside of the sampling tube 5.

[0038] As attached Figure 2 As shown, a disassembly assembly is provided on one side of the storage tank 2. The disassembly assembly includes an internally threaded tube 16, which is connected through to one side of the storage tank 2. An externally threaded tube 17 is connected to the internal thread of the internally threaded tube 16. The externally threaded tube 17 is rotatably connected to one end of the flow tube 3. Handles 18 are fixedly connected to both sides of the storage tank 2. A second limiting plate 25 is fixedly connected to the upper surface of the base plate 1.

[0043] Working principle: When sampling water, this utility model is first transported to the shore of the water body, and then the sampling tube 5 is inserted into the water body. The water pump 4 is then turned on, using its input end to draw water. Before entering the sampling tube 5, the water flows through the spherical filter frame 9, where large particles of impurities are intercepted and retained on the outside. The filtered water then flows into the sampling tube 5. When the spherical filter frame 9 is covered with impurities, the underwater motor 13 is turned on. When the output end of the device is turned on, the gear 14 rotates, and the gear 14 meshes with the gear ring 12, causing the gear ring 12 to rotate. The gear ring 12 then causes the rotating ring 7 to rotate. When the rotating ring 7 rotates, it causes the arc-shaped scraper 10 and the inner brush plate 11 to move synchronously. The arc-shaped scraper 10 scrapes the outside of the spherical filter frame 9 to remove impurities, while the inner brush plate 11 scrapes the inner wall of the spherical filter frame 9 to prevent impurities from being scraped into the spherical filter frame 9 by the arc-shaped scraper 10.

[0044] When the storage tank 2 is full of water and needs to be replaced, first turn the handle 22. The handle 22 drives the stud 21 to rotate inside the mounting groove 19, so that the stud 21 drives the moving block 23 to slide inside the mounting groove 19, thereby causing the first limiting plate 24 to move away from the side of the storage tank 2. Then, hold the handles 18 on both sides and lift the storage tank 2, so that the caster 27 is lifted from inside the placement groove 20. Then, turn the external thread tube 17 to separate the external thread tube 17 from the internal thread tube 16, thereby separating the storage tank 2. Then, use the threaded cap to cover one end of the internal thread tube 16 to prevent water from overflowing. With the help of the caster 27, it is easy to transport the storage tank 2.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
