Description

Technical Field

[0001] This utility model belongs to the technical field of water quality samplers, and in particular relates to an anti-clogging structure for water quality samplers. Background Technology

[0002] Artificial water samplers are simple to use and have low cost. They are suitable for collecting large amounts of water samples for preliminary observation or simple analysis. They are commonly used in sampling locations such as ponds and shallow water areas of rivers. They can collect water samples directly from or near the surface of the water body.

[0003] Due to the different water quality samples, small floating objects or impurities may be introduced into the sampling tube when the water sample is poured in, resulting in a large mixture and blockage at the inlet of the sampling tube, which increases the difficulty of sampling. In order to avoid blockage at the sampling port, we propose an anti-clogging structure for a water quality sampler with a filtering function to solve the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging structure for a water sampler, which filters the sampling port to prevent clogging, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A water quality sampler anti-clogging structure includes a sampling cylinder. A hollow threaded disc is fixedly connected to the top of the inner cavity of the sampling cylinder. A filter cylinder is threadedly connected to the surface of the threaded disc. A vertical cylinder is rotatably connected to the top axis of the filter cylinder via a bearing. A sliding plate is slidably connected to the inner cavity of the vertical cylinder. A vertical rod is fixedly connected to the top of the sliding plate. A horizontal plate is fixedly connected to the top of the vertical rod. Vertical plates are fixedly connected to both sides of the horizontal plate. A scraper is fixedly connected to the bottom of the vertical plate. A spring is fixedly connected to the bottom of the inner cavity of the vertical cylinder. The top of the spring is fixedly connected to the bottom of the sliding plate. A limiting shaft is fixedly connected to both the bottom of the sliding plate and the bottom of the inner cavity of the vertical cylinder. The limiting shaft is sleeved on the inner surface of the spring.

[0006] Preferably, guide grooves are provided on both sides of the inner cavity of the vertical cylinder, and guide blocks that are adapted to and slidably connected to the guide grooves are fixedly connected to both sides of the surface of the sliding plate.

[0007] Preferably, a drain pipe is connected to the bottom of the sampling tube surface, and a valve is movably connected to the opening of the drain pipe.

[0008] Preferably, when the horizontal plate is pressed, the bottom of the scraper contacts the convex edge of the threaded disc.

[0009] Preferably, the scraper is shovel-shaped and is centrally symmetrical about the axis of the filter cartridge.

[0010] Preferably, the surface of the filter cartridge is provided with a filter screen structure, and the top end face of the filter cartridge is lower than the top end face of the sampling cartridge.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model involves inserting a sampling tube into the desired sampling location. A certain amount of water is poured into the inlet of the sampling tube. As the water passes through the filter tube, it is filtered, blocking some floating objects or debris. Smaller impurities accumulate between the threaded disc and the sampling tube. At this point, simply press the horizontal plate to make the vertical rod slide on the inner surface of the vertical tube through the sliding plate and press the spring. At the same time, rotate the horizontal plate to make the scraper at the bottom of the vertical plate rotate, thereby using the scraper to clean the accumulated debris, thus ensuring the filtration effect of the filter tube and filtering the sampling port to prevent clogging.

[0013] 2. This utility model guides the up-and-down movement of the sliding plate by sliding the guide block on the inner surface of the guide groove. At the same time, it can limit the vertical rod, so that the vertical rod drives the vertical cylinder to rotate, and drives the vertical plate to rotate through the bearing.

[0014] 3. This utility model can discharge the sampled water by setting up a drain pipe;

[0015] 4. This utility model uses a scraper in the shape of a shovel to scrape away debris generated in the gap between the sampling cylinder and the threaded disc, thus facilitating cleaning. Attached Figure Description

[0028] Working Principle: When using this invention, the user inserts the sampling tube 1 into the desired sampling location. A certain amount of water is poured into the opening of the sampling tube 1. As the water passes through the filter tube 3, it is filtered, blocking some floating objects or debris. Smaller impurities accumulate between the threaded disc 2 and the sampling tube 1. At this point, simply press the horizontal plate 7, causing the vertical rod 6 to slide on the inner surface of the vertical tube 4 via the sliding plate 5, and press the spring 10. The limiting shaft 11 supports the position of the spring 10. Simultaneously, rotating the horizontal plate 7, through the guide block 13 sliding connection on the inner surface of the guide groove 12, limits the vertical rod 6, causing the vertical rod 6 to drive the vertical tube 4 to rotate, and through the bearing, driving the vertical plate 8 to rotate, causing the scraper 9 at the bottom of the vertical plate 8 to rotate, thereby using the scraper 9 to clean the accumulated debris. After cleaning, the spring 10 springs up, causing the horizontal plate 7 to return to its original position, thus ensuring the filtration effect of the filter tube 3, thereby filtering the sampling port and preventing blockage.
