Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

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.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Combination Figures 2 to 7 A water sample multi-point collection device includes a bottom disc 1, a collection mechanism 2 fixedly connected to the top of the bottom disc 1, and a lifting mechanism 3 fixedly connected to the top of the collection mechanism 2.

[0031] The data acquisition mechanism 2 includes a threaded disc 21, which is located on top of the bottom disc 1. Pull ropes 22 are fixedly connected to the surface of the threaded disc 21. An ear plate seat 23 is fixedly connected to the bottom edge of the bottom disc 1. Torsion springs 24 are fixedly connected to both ends of the ear plate seat 23. An I-shaped rod 25 is fixedly connected to one end of each torsion spring 24. An L-shaped frame 26 is fixedly connected to the surface of the I-shaped rod 25. A data acquisition device 27 is fixedly connected to one end of the top of the L-shaped frame 26. A support strip 28 is fixedly connected to the middle of the top of the L-shaped frame 26. A support rod 29 is fixedly connected to the bottom of the bottom disc 1. A first pulley 291 is fixedly connected to the top of the bottom disc 1 near the surface of the threaded disc 21. A second pulley 292 is fixedly connected to the top edge of the bottom disc 1. A sliding hole is opened inside the threaded disc 21. The surface of the support rod 29 is slidably connected to the inside of the sliding hole. The upper surface of the pull rope 22 is tightly attached to the surface of the first pulley 291. The lower surface of the pull rope 22 is tightly attached to the surface of the second pulley 292. One end of the pull rope 22 is fixedly connected to the inside of the left end of the L-shaped frame 26.

[0032] Furthermore, a rotating hole is opened inside the ear plate seat 23, and the surface of the I-shaped rod 25 is rotatably connected to the inside of the rotating hole. Pulling the pull rope 22 moves the device and, with the support of the ear plate seat 23 and the first pulley 291, drives one end of the L-shaped frame 26 to rotate with the support of the I-shaped rod 25. This rotates the collection device 27 at one end of the L-shaped frame 26 from the top to the bottom of the L-shaped frame 26. At this time, the L-shaped frame 26 has been flipped, so the collection device 27 can be unfolded and multi-point water body collection can be performed simultaneously, thereby improving the water body sample collection efficiency. After the collection is completed, the above structure facilitates its storage.

[0033] Example 2

[0034] See Figure 1-7 Furthermore, based on Embodiment 1, the lifting mechanism 3 includes a ring 31, which is fixedly connected to the top of the support rod 29. A threaded ring 38 is rotatably connected to the top of the ring 31. A cylinder 32 is provided at the top of the threaded ring 38. A limiting ring 33 is slidably connected inside the cylinder 32. A positioning rod 34 is fixedly connected to the bottom end of the limiting ring 33. A second spring 35 is fixedly connected to the front of the cylinder 32 near the bottom end. A T-shaped rod 36 is fixedly connected to one end of the second spring 35. A handle 37 is fixedly connected to the top of the cylinder 32. A lever 37 is rotatably connected to the bottom end of the positioning rod 34. The lead screw 39 has its upper surface fixedly connected to the inside of the threaded ring 38, its bottom end rotatably connected to the top of the bottom disc 1, and its surface threadedly connected to the middle of the inside of the threaded disc 21. A through hole is opened inside the ring 31, and the surface of the lead screw 39 passes through the through hole opened inside the ring 31. The top end of the lead screw 39 is rotatably connected to the bottom end of the positioning rod 34. A through hole is opened on the front side of the cylinder 32 near the bottom end, and the surface of the T-shaped rod 36 passes through the through hole opened on the front side of the cylinder 32 near the bottom end. A positioning hole is opened on the surface of the positioning rod 34, and the surface of the T-shaped rod 36 matches the inside of the positioning hole.

[0035] Furthermore, a circular groove is formed inside the cylinder 32, and the surface of the positioning rod 34 is slidably connected to the inside of the circular groove. A limiting groove is formed inside the circular groove, and the surface of the limiting circular bar 33 is slidably connected to the inside of the limiting circular groove. By moving the cylinder 32 upward and allowing the limiting circular bar 33 to slide inside the cylinder 32, the length of the positioning rod 34 and the cylinder 32 can be increased. After adjusting to a certain length, the T-shaped rod 36 can be inserted into the positioning rod 34, ultimately realizing the collection operation at different water depths.

[0036] In actual operation, when this device is used and multiple water level points need to be detected, the device is submerged in the water and can be unfolded. Rotating the threaded ring 38 drives the screw 39 to rotate, thereby causing the threaded disc 21 to move upward under the limiting action of the support rod 29. This pulls the rope 22 to move and, with the support of the ear plate seat 23 and the first pulley 291, drives one end of the L-shaped frame 26 to rotate with the support of the I-shaped rod 25. This rotates the collection device 27 at one end of the L-shaped frame 26 from the top to the bottom of the L-shaped frame 26. At this time, the L-shaped frame 26 has been rotated 180 degrees, so the collection device 27 can be unfolded and multi-point water level collection can be performed. After the collection is completed, the above structure makes it easy to store the device.

[0037] In addition, when it is necessary to collect water samples at different depths, the T-shaped rod 36 can be pulled out and disengaged from the locking position inside the positioning rod 34. Then, the cylinder 32 can be moved upward and the limiting bar 33 can be slid inside the cylinder 32, thereby increasing the length of the positioning rod 34 and the cylinder 32. After adjusting the length to a certain extent, the T-shaped rod 36 can be locked into the positioning rod 34, thus realizing the collection operation at different water depths.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used merely 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. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
