Abstract
Description
A deep-water sampler capable of filtration Technical Field
[0001] This utility model relates to the field of sampler technology, specifically a deep-water sampler capable of filtration. Background Technology
[0002] Deep-water samplers are made of colorless and transparent plexiglass and are suitable for collecting water samples during water quality or plankton analysis by environmental protection and other relevant departments. They are a commonly used tool for manual water sampling and are primarily used in environmental protection, disease control, water supply, and chemical industries. Deep-water samplers are designed to facilitate sampling and research in deeper water areas, storing water sources internally for easy sampling and analysis.
[0003] For example, Chinese utility model patent CN213516462U discloses a water quality sampler for easy sampling in deep water areas. The sampler includes a cylindrical body and a water level observation window. A counterweight is located at the bottom of the cylindrical body, and a water outlet pipe is connected to the side of the cylindrical body near the counterweight. Fixing grooves are formed at both ends of the inner side of the through-hole. The water level observation window is located inside the through-hole and is installed in the fixing groove via a connecting strip. A sleeve is fixed to the bottom of the cylindrical body, and the sleeve is connected to one end of the water outlet pipe. A collection bucket is located inside the cylindrical body near the top of the sleeve. This water quality sampler facilitates sampling in deep water areas. By rotating a fixing rod perpendicular to the inside of the collection bucket, the bottom of the collection bucket and the sleeve are threaded together, causing the collection bucket and sleeve to disassemble and detach. The collection bucket can then be removed from the inside of the cylindrical body using the fixing rod, thus facilitating regular cleaning of the sampler's interior.
[0004] However, existing deep-water sampler filtration devices place the filter screen inside the housing, making it inconvenient to remove the filter screen for more thorough cleaning or replacement when the collection cylinder is removed, which can easily lead to impurities remaining.
[0005] To address these issues, we propose a filtered deep-water sampler. Summary of the Invention

[0008] An annular mounting groove is formed on the bottom surface of the upper cover plate. Limiting grooves are formed on both sides of the annular mounting groove. A connecting block contacts the annular mounting groove. A filter frame is fixedly installed on the bottom surface of the connecting block. Limiting blocks are fixedly connected to both sides of the connecting block. The limiting blocks are engaged with the limiting grooves. A horizontal through hole one is formed in the upper cover plate. A through hole two is formed on one side of the connecting block. A through hole three is formed on one side of the limiting block. A connecting rod passes through the through holes one, two, and three. A limiting rod is fixedly connected to the end of the connecting rod. A limiting nut is threadedly connected to the threaded part of the connecting rod.
[0009] Preferably, two fixing seats are fixedly connected to both ends of the top surface of the upper cover plate, and two horizontal shafts are horizontally fixed between the two fixing seats on the side that is close to each other.
[0010] Preferably, the outer walls of the two horizontal axes are respectively rotatably connected to rotating blocks, and a water intake cover is fixed to one side of each rotating block.
[0011] Preferably, the through hole one, the limiting groove, and the annular mounting groove are internally connected, and the through hole one, through hole two, and through hole three are internally connected.
[0012] Preferably, the outer wall of the sampling tube is provided with a water level scale line, and a water outlet is fixedly installed at the bottom of the sampling tube, and the water outlet is connected to the inside of the sampling tube.
[0013] Preferably, two mounting bases are fixedly installed on both sides of the top of the sampling tube, and each mounting base is equipped with a lifting ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model can filter sampled water by setting a filter screen frame.
