Description

Technical Field

[0001] This utility model relates to the field of river sampling technology, specifically to an evaluation sampling device. Background Technology

[0002] Water samplers can conveniently collect water samples from rivers and other water sources to monitor whether the water quality meets relevant standards. They can also monitor changes in water quality upstream and downstream of water conservancy projects, assess the impact and scope of these projects on the river's ecological environment, and ensure that water quality meets relevant standards and requirements. Furthermore, regular collection and analysis of water samples can promptly identify potential problems with water conservancy facilities, such as leakage and pollution, providing a scientific basis for the maintenance and management of water conservancy projects. However, existing water samplers all use a method where a rope is tied to a bucket, which is then placed on the water surface and allowed to slowly sink. This method makes it difficult to accurately control the sampling depth, and it requires operators to be close to the bank, posing a safety hazard. Therefore, a device is needed that can collect water from a distance and allows the bucket to be placed on the lower water surface before sampling.

[0003] Chinese Patent Publication No. CN217638186U discloses a river ecological environment assessment sampling device, including a collection box, a transmission box, and a suction tube. The transmission box is located at the top of the collection box, and the suction tube is located at the bottom of the collection box. The collection box is equipped with an extraction mechanism, and the suction tube is equipped with a blocking mechanism. This utility model, by setting up an extraction mechanism, a blocking mechanism, and a limiting mechanism, uses the extraction mechanism to extract water from the river into the collection box, the blocking mechanism to prevent the extracted water from spilling, and the limiting mechanism to limit the blocking plate. It has the advantage of facilitating sampling and solves the problem that existing river environmental sampling methods use buckets, which require throwing the bucket into the river, and the bucket may float directly on the water surface, requiring the user to manually adjust the position of the bucket before filling, thus reducing the practicality of existing sampling devices.

[0004] However, this utility model has the following problems in actual use:

[0005] In practical use, due to its strong airtightness, this utility model is difficult to open, making it difficult to remove residual water samples, dirt, and impurities inside. Over time, this accumulation will affect the performance and sampling accuracy of the collector. If the inside of the collector is not thoroughly cleaned during multiple sampling processes, it will lead to cross-contamination between different water samples, thereby affecting the reliability of the data.

At this time, the baffle 3 is lifted, and water flows into the glass cover 5 from the inner wall of the limiting ring 18. Wait for a period of time to allow the glass cover 5 to be filled with enough water sample. When extracting the device, hold the handle 8 with your left hand and the anti-slip sleeve 11 with your right hand and press down so that the bottom of the baffle 3 contacts the top of the limiting ring 18 to block the water inlet base 6 to prevent water leakage. After lifting the glass cover 5 out of the water, drain the water sample from the glass cover 5 through the water outlet pipe 16 and collect the water sample into a suitable container for subsequent evaluation and analysis. When cleaning the device, simply pull the glass cover 5 directly off the bottom of the cover 4 for cleaning.
