Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a multi-level sampling device for water environment engineering testing. Background Technology

[0002] Environmental engineering is a branch of environmental science that mainly studies how to protect and rationally utilize natural resources, and uses scientific methods to solve increasingly serious environmental problems, improve environmental quality, and promote environmental protection and social development. It is the science and technology that studies and engages in the prevention and control of environmental pollution and the improvement of environmental quality. Water sampling is the collection of water samples from polluted water bodies, which are then analyzed to obtain basic data on water pollution. The water samples used for analysis should be representative and reflect the chemical composition and characteristics of the water body.

[0003] To prevent foreign matter and impurities from entering the sampling container, existing water sampling devices typically have a filter screen at the inlet to block these impurities. However, when there is a large amount of foreign matter and impurities, the filter screen can easily become clogged, hindering normal water sampling and reducing sampling efficiency. Therefore, we propose a multi-level water sampling device for water environment engineering testing. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a multi-level sampling device for water environment engineering testing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-level sampling device for water environment engineering testing, comprising a sampling cylinder and a collection bottle. Several sets of partitions are installed inside the sampling cylinder, and the inside of the sampling cylinder is divided into several storage cavities by these partitions. The collection bottle is placed inside the storage cavity. An installation groove is provided on the periphery of the sampling cylinder, and a liquid inlet guide pipe is installed inside the installation groove. A barrier net is provided at the port of the guide pipe. A circular component is provided inside the guide pipe, and an opening is provided inside the barrier net. A through-hole insertion shaft is installed at one end of the circular component, and a hook for hooking and trapping foreign objects is installed around the insertion shaft. The periphery of the circular component is supported and connected to the inside of the guide pipe by a support mechanism.

[0006] Preferably, when the water source enters the collection bottle through the guide pipe, foreign objects in the water source are punctured and intercepted by multiple sets of insert shafts, and several sets of hooks on the outside of the insert shafts provide auxiliary interception for the foreign objects in the water source.

[0007] Preferably, the collection bottle has a connection interface on its periphery, and the periphery of the collection bottle is connected and installed with the outside of the guide tube through the connection interface.

[0008] Preferably, the sampling tube has a connecting groove on its periphery, and a closing cover is rotatably connected to one side of the connecting groove. A pull ring is installed on the periphery of the closing cover.

[0009] Preferably, rectangular grooves are provided at both the connecting groove and the edge of the closed cover, and magnetic suction components are installed inside the rectangular grooves, with the magnetic suction components having magnetic attraction properties.

[0012] Beneficial effects:

[0013] 1. A multi-level sampling device for water environment engineering testing. In this paper, the barrier net has multiple sets of openings through which insert shafts pass, and several sets of hooks are installed on the outside of the insert shafts. After the sampling tube is placed in the water source, the water source can enter the collection bottle through the barrier net inside the guide tube. Larger foreign objects mixed in the water source will be pierced and blocked by the multiple sets of insert shafts when they approach the barrier net, while smaller foreign objects will be intercepted and blocked by the multiple sets of hooks when they approach the barrier net. This allows the water source to be filtered normally through the barrier net and enter the collection, avoiding blockage caused by foreign objects, thereby improving the water source sampling efficiency.

A liquid inlet guide pipe 4 is installed inside the installation groove 3. A barrier net 5 is installed at the end of the guide pipe 4. A circular component 6 is installed inside the guide pipe 4. An opening 7 is provided inside the barrier net 5. A through-hole shaft 8 is installed at one end of the circular component 6, and a hook for trapping and retaining foreign objects is installed around the shaft 8. The hook 9 and the outer periphery of the circular part 6 are supported and connected to the inner side of the guide tube 4 through the support mechanism 10. The outer periphery of the collection bottle 2 is provided with a docking interface 11, and the outer periphery of the collection bottle 2 is connected to the outer side of the guide tube 4 through the docking interface 11.

After the sampling tube 1 is placed in the water source, the water source can enter the collection bottle 2 through the barrier net 5 inside the guide pipe 4. Larger foreign objects mixed in the water source will be pierced and blocked by the multiple sets of insert shafts 8 when they approach the barrier net 5, while smaller foreign objects will be intercepted and blocked by the multiple sets of hooks 9 when they approach the barrier net 5. This allows the water source to pass through the barrier net 5 normally for filtration and collection, avoiding blockage by foreign objects, thereby improving the water source sampling efficiency.
