For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Combination Figures 2 to 7 A water quality sampling device includes a water tank 1, a filter mechanism 2 fixedly connected to the bottom of the water tank 1, and a lifting mechanism 3 fixedly connected to the top of the water tank 1.

[0034] Filter mechanism 2 includes a hard water pipe 21, which is fixedly connected to the top of the water tank 1. A tapered tube 22 is fixedly connected to the bottom of the hard water pipe 21. A supporting base cylinder 23 is fixedly connected to the bottom of the tapered tube 22. A filter screen 24 is installed at the bottom of the supporting base cylinder 23. An L-shaped strip 25 is fixedly connected to the bottom of the filter screen 24. An arc-shaped socket 26 is fixedly connected to the top of the L-shaped strip 25. T-shaped strips 251 are fixedly connected to the left and right sides of the supporting base cylinder 23. Arc-shaped limiting strips 29 are fixedly connected to the front and rear sides of the surface of the supporting base cylinder 23. A rotating ring 27 is installed on the surface of the arc-shaped limiting strip 29. An arc-shaped strip 271 is fixedly connected to the inner side of the rotating ring 27. A support plate 273 is fixedly connected to the top of the rotating ring 27. A first spring 272 is fixedly connected to one end of plate 273. A ring 274 is fixedly connected to one end of the first spring 272. The inner side of the ring 274 is fixedly connected to the upper surface of the support base cylinder 23. A second spring 282 is fixedly connected to the top of the support base cylinder 23. A cross ring 28 is fixedly connected to the bottom of the second spring 282. A telescopic tube 281 is fixedly connected to the top of the cross ring 28 and the top of the support base cylinder 23. Sliding grooves are opened at the four ends of the support base cylinder 23. The four ends of the cross ring 28 are slidably connected to the inside of the sliding grooves. A limiting groove is opened inside the L-shaped strip 25. The surface of the T-shaped strip 251 is slidably connected to the inside of the limiting groove. A round hole is opened inside the cross ring 28. The surface of the filter screen 24 is tightly fitted to the inside of the round hole.

[0035] Furthermore, an arc-shaped hole is opened inside one end of the arc-shaped socket 26, and one end of the surface of the arc-shaped strip 271 matches the inside of the arc-shaped hole. An annular groove is opened on the inner side of the rotating ring 27, and the surface of the arc-shaped limiting strip 29 is slidably connected to the inside of the annular groove. When the filter screen 24 is disassembled and cleaned, rotating the rotating ring 27 will cause the arc-shaped strip 271 to disengage from the inside of the arc-shaped socket 26, thereby releasing the limiting of the arc-shaped socket 26. Then, the L-shaped strip 25 can be used to move the arc-shaped socket 26 downward and cause the filter screen 24 to disengage from the inside of the supporting bottom cylinder 23. This makes it easy to disassemble and clean the filter screen 24, and ensures normal water sampling.

[0036] Example 2

[0037] See Figure 1-7Furthermore, based on Embodiment 1, the lifting mechanism 3 further includes a support base 31, which is fixedly connected to the top of the water tank 1. A cross block 33 is slidably connected inside the support base 31. A support rod 32 is fixedly connected to the top of the cross block 33. A top plate 391 is fixedly connected to the top of the support rod 32. A third spring 34 is fixedly connected inside the cross block 33. A limit plate 35 is fixedly connected to one end of the third spring 34. A T-shaped rod 36 is fixedly connected inside the limit plate 35. A connecting strip 37 is fixedly connected to one end of the back of the T-shaped rod 36. A retaining strip 38 is fixedly connected to both ends of the connecting strip 37. A positioning plate 39 is fixedly connected to the back of the support base 31. A cross groove is opened inside the support base 31. The surface of the cross block 33 is slidably connected to the inside of the cross groove. A rectangular groove is opened inside the cross block 33. The surface of the limit plate 35 is slidably connected to the inside of the rectangular groove.

[0038] Furthermore, a positioning hole is opened inside the positioning plate 39, and the surface of the locking strip 38 matches the inside of the positioning hole. When the T-shaped rod 36 is pressed and the connecting strip 37 is moved, the locking strip 38 is disengaged from the locking position inside the positioning plate 39, so that the cross block 33 can slide arbitrarily inside the support base 31, and the distance between the top plate 391 and the support base 31 can be changed. In this way, the support bottom cylinder 23 can be adjusted to different depths, which makes it convenient to sample water quality at different water depths.

[0039] In actual operation, when this device is in use, a water pump is installed inside the water tank 1, and a water intake port is opened on the top back of the water tank 1. During water quality sampling and testing, when pumping water for testing, the top plate 391 is fixed outside the water surface. At this time, the water pump installed inside the water tank 1 pumps water and extracts it from the bottom of the supporting base cylinder 23. During the extraction process, it is necessary to filter water impurities. The filter screen 24 can be used for corresponding filtration to ensure the quality of water sampling. In addition, when it is necessary to clean the filter screen 24, it can be put into the filter. Disassembly and cleaning are performed by rotating the rotating ring 27 to disengage the arc-shaped strip 271 from the arc-shaped socket 26, thereby releasing the limit of the arc-shaped socket 26. Then, the L-shaped strip 25 can be used to move the arc-shaped socket 26 downward and disengage the filter screen 24 from the support base cylinder 23, thus facilitating the disassembly and cleaning of the filter screen 24. This effectively ensures normal extraction during each water quality sampling. Furthermore, the elasticity of the second spring 282 can be used to tightly fit the cross ring 28 with the surface of the filter screen 24, ensuring the water quality is sealed.

[0040] Furthermore, when sampling is required for water quality at different depths, pressing the T-shaped rod 36 causes the connecting strip 37 to move, which in turn causes the locking strip 38 to disengage from the locking position inside the positioning plate 39. This allows the cross block 33 to slide freely inside the support base 31 and changes the distance between the top plate 391 and the support base 31. Consequently, the support base cylinder 23 can be adjusted to different depths, making it convenient to sample water quality at different depths.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
