Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy exploration, and more specifically, to a water sampling device. Background Technology
[0002] In the field of water exploration, water sampling is a crucial step, playing an indispensable role in water quality analysis, water resource assessment, and water conservancy project design. Water sampling devices, as the tools for achieving this key step, directly affect the accuracy and efficiency of water sample collection. With the continuous development of water exploration technology, the requirements for water sampling devices are also increasing. They not only need to possess efficient and stable sampling capabilities but also require ease of operation, strong adaptability, and the ability to adapt to various complex aquatic environments.
[0003] Existing water sampling devices still have some problems in use:
[0004] Existing water sampling devices often lack effective filtration mechanisms when extracting water samples, which may result in the presence of various impurities such as suspended solids, silt, and plant and animal remains in the extracted water samples. The presence of these impurities not only affects the clarity and transparency of the water samples, but may also interfere with the subsequent water quality analysis process, leading to inaccurate or misleading analysis results.
[0005] Existing water sampling devices typically use manual methods to pump water through pipes. However, in actual operation, it is often difficult to keep the pipes vertical. When the operator holds the pipe deep into the water to pump water, the pipe is easily tilted or deflected due to external factors such as water flow and wind. This makes it difficult for the operator to accurately judge the actual pumping depth of the pipe, and the unstable position of the pipe may also result in the pumped water samples not being representative.
[0006] Therefore, we have made improvements to this and proposed a water sampling device. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a water sampling device that solves the problems mentioned in the background section.
[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0009] A water sampling device includes a water pump, a pumping pipe fixedly installed on one side surface of the pump, and a drain pipe fixedly connected to the other side surface of the pump. A connector is fixedly installed at the other end of the pumping pipe. A filter mechanism is installed on the surface of the connector, and a connector is fixedly installed on the upper surface of the connector. A connecting block is fixedly installed on the upper surface of the connector, and several fixing rods are connected to the upper surface of the connecting block. A connecting mechanism is provided between the connecting block and the fixing rods and between the fixing rods.
[0010] As a preferred technical solution of this application, the filtering mechanism includes a fixing head, which is disposed outside one end of the connector. A fixing ring is engaged inside the fixing head, and a filter screen is fixedly installed inside the fixing ring.
[0011] As a preferred technical solution of this application, the inner surface of the fixing head is provided with a threaded groove, and the connecting head is threadedly connected to the fixing head through the threaded groove.
[0012] As a preferred technical solution of this application, the connecting mechanism includes a slot and a block, with the slot being formed on the upper surface of the fixed head and several fixed rods, and the block being fixedly installed on the lower surface of the several fixed rods, and the block and the slot being connected by a snap-fit connection.
[0013] As a preferred technical solution of this application, protrusions are fixedly installed on both sides of the inner wall of the card slot, and two L-shaped sliding grooves are opened on the outer surface of the card block, and the connection between the protrusions and the sliding grooves is a sliding connection.

[0015] As a preferred technical solution of this application, the external sliding connection of the fixing rod has several buckles, and the buckles are connected to the water pipe by a snap-fit connection.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The filtration mechanism consists of a fixed head, a fixed ring, and a filter screen, which are securely installed on the connector head via a threaded connection. This ensures that the water sample must pass through the filter screen during the extraction process, effectively removing suspended solids, silt, plant and animal remains, and other impurities from the water sample. This improves the clarity and transparency of the water sample and significantly reduces the interference of impurities on subsequent water quality analysis, thereby improving the accuracy and reliability of the analysis results.
[0018] 2. The connection mechanism, which combines a slot and a block design, allows the fixing rod to be securely connected to the connecting block. It also allows for flexible adjustment of the length of the fixing rod as needed. The scale lines on the outer surface of the fixing rod can accurately determine the actual pumping depth of the pipeline, avoiding sampling errors caused by pipeline tilting or deflection.
