Description
Technical Field
[0001] This utility model relates to the field of water quality testing and extraction technology, and in particular to a water quality testing and extraction device. Background Technology
[0002] With the development of modern industry, environmental pollution is also constantly worsening. As water resources on which humans depend for survival are increasingly valued, water pollution is becoming more and more important. In order to ensure the sustainable development of water resources, water body testing and research have become essential tasks. When testing water quality, the first step is to collect water samples.
[0003] An existing water quality testing extraction device (publication number: CN221707011U) has at least the following drawbacks: Although the above device moves the drive box along the slide direction through the moving mechanism, so that the water quality extractor moves above the extraction point and then takes a sample, its operation relies on multiple motors and hydraulic cylinders, and the overall structure is relatively complex. This not only increases the weight and volume of the device, making it inconvenient to transport over long distances, but also makes rapid deployment in complex outdoor terrain difficult, thereby reducing the efficiency of water quality testing. Therefore, we propose this utility model. Utility Model Content

An extraction structure for extracting water quality is provided at the tail end of the rod. The connecting structure includes a connecting cylinder disposed between two adjacent rods. The rod on the left side is fixed inside the connecting cylinder, while the rod on the right side is slidably inserted inside the connecting cylinder. Two L-shaped sliding grooves are formed on the inner circular wall of the connecting cylinder. A sliding shaft is slidably disposed inside the sliding groove, and the sliding shaft is fixed to the outer circular wall of the corresponding rod.
[0007] As a further embodiment of this utility model, the right end of the connecting cylinder has two snap-fit holes, which are respectively connected to two sliding grooves. A limiting shaft is slidably inserted inside the snap-fit holes. The bottom surface of the limiting shaft is in contact with the outer circular wall surface of the sliding shaft. A magnetic sheet is fixed on one side of the inner wall of the sliding groove, and the magnetic sheet is magnetically connected to the corresponding end of the limiting shaft.
[0008] As a further embodiment of this utility model, the extraction structure is set in the water sampler below the pole body. The top of the water sampler is fixed with a traction rope by a buckle. The left end of the first section of the pole body is fixed with an installation plate. A winding shaft is rotatably installed inside the installation plate. A motor is fixed on one side of the installation plate. The output end of the motor passes through one side of the installation plate and is fixed to one end of the winding shaft. One end of the traction rope passes through the interior of several pole bodies and the installation plate and is wound and fixed to the outer circular wall of the winding shaft.
[0009] As a further embodiment of this utility model, the outer circular wall of the connecting cylinder is threaded with a bolt, and a connecting plate is rotatably provided at the bottom end of the bolt, with the connecting plate fitting against the outer circular wall of the corresponding two rods.

A motor is fixed on one side of the mounting plate 302. The output end of the motor passes through one side of the mounting plate 302 and is fixed to one end of the winding shaft 303. One end of the traction rope 301 passes through the interior of several rods 1 and the mounting plate 302 and is wound and fixed to the outer circular wall of the winding shaft 303. The water sampler 3 is existing technology. Through the setting of the connecting structure and the extraction structure, the user can select an appropriate number of rods 1 according to the sampling distance and insert the rods 1 into the corresponding connecting cylinder 2 in sequence. When the rods 1 are inserted into the connecting cylinder 2, the sliding shaft 202 slides along the sliding groove 201 to the designated position. Subsequently, The user rotates the rod 1 to accurately insert the sliding shaft 202 into the corresponding position of the sliding groove 201, completing the initial engagement. Next, the user inserts the limiting shaft 204 into the engagement hole 203, allowing it to enter the sliding groove 201 and be magnetically fixed with the magnetic piece 205, thereby limiting the sliding shaft 202 and preventing the rod 1 from accidentally rotating and sliding out of the connecting cylinder 2, further improving the connection stability.

When the rods 1 are inserted into the connecting cylinders 2, the sliding shaft 202 slides into the designated position along the sliding groove 201. Then, the user rotates the rods 1 so that the sliding shaft 202 is accurately embedded in the corresponding position of the sliding groove 201, completing the initial engagement. Next, the user inserts the limiting shaft 204 into the engagement hole 203, so that it enters the sliding groove 201 and is magnetically fixed with the magnetic piece 205, thereby limiting the sliding shaft 202 and preventing the rods 1 from accidentally rotating and sliding out of the connecting cylinder 2, further improving the connection stability.
