Detailed implementation mode
[0026] The technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are only examples, and the extendable probe rod for water sample collection involved in the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0027] Referring to Figure 1-7 , the present utility model provides an extendable probe rod for water sample collection, including:
[0028] A telescopic structure 1, the telescopic structure 1 includes a telescopic cylinder 12, a telescopic rod 13 and a connecting ring 14, and there are three groups of connecting rings 14, and a rope body 3 is inserted inside the four groups of connecting rings 14. The telescopic structure 1 is used for the telescoping of the device. The telescopic structure 1 further includes a handle 11, and the handle 11 is fixedly connected to the surface of one end of the telescopic cylinder 12, and the telescopic rod 13 is inserted inside the other end of the telescopic cylinder 12. One ends of the three groups of connecting rings 14 are respectively fixedly connected to the outer surfaces of one side of the handle 11, the telescopic cylinder 12 and the telescopic rod 13. A square groove is opened on the upper surface of the other end of the telescopic cylinder 12, and a limiting strip is arranged on the lower surface inside the telescopic cylinder 12. A clamping groove is opened on the upper surface of the telescopic rod 13, and a limiting groove is opened on the lower surface of the telescopic rod 13, and the size of the limiting groove is adapted to the size of the limiting strip arranged on the lower surface inside the telescopic cylinder 12. According to Figure 2 And Figure 3 As shown, when the telescopic rod 13 telescopes inside the telescopic cylinder 12, due to the arrangement of the limiting strip and the limiting groove, the telescopic rod 13 will not rotate inside the telescopic cylinder 12. This design makes the telescoping process of the telescopic rod 13 more stable and prevents the water source collected inside the collection cylinder 5 from spilling out.
[0029] Engaging structure 2, the engaging structure 2 includes a fixed ring 21, and the inner surface of the fixed ring 21 is fixedly connected to the outer surface of one end of the telescopic cylinder 12. The engaging structure 2 is used to fix the telescopic state of the telescopic structure 1. The engaging structure 2 also includes a fixed seat 22, and the fixed seat 22 is fixedly connected to the upper surface of the fixed ring 21. And a fixed column 23 is fixedly connected inside the fixed seat 22. A pressing column 24 is sleeved on the outer surface of the middle position of the fixed column 23. And a handle 25 is fixedly connected to the outer surface of one side of the pressing column 24. A pressing block 26 is inserted into the upper end of the fixed ring 21. And the lower end of the pressing block 26 fits into the engaging groove opened on the upper surface of the telescopic rod 13. And the pressing block 26 is inserted into the square groove opened on the upper surface of the other end of the telescopic cylinder 12. The lower surface of the pressing column 24 fits on the upper surface of the pressing block 26. And an anti-slip pad is arranged at the lower end of the pressing block 26. And the material of the anti-slip pad is rubber. According to Figure 4 and Figure 5 shown, the center of the fixed column 23 deviates from the center of the pressing column 24. This design makes the pressing column 24 move downward against the pressing block 26 when rotating around the fixed column 23. When the pressing block 26 moves downward, its lower surface will abut against the engaging groove opened on the upper surface of the telescopic rod 13. And the rubber material has certain viscosity and elasticity, and can generate a large frictional force during the friction process. This design enables the engaging structure 2 to fix the telescopic state of the rope body 3.
[0030] Rope body 3, a floating structure 4 is clamped on the outer surface of the rope body 3. And a collecting cylinder 5 is inserted into the inside of one end of the rope body 3. The rope body 3 is used to adjust the height of the collecting cylinder 5;
[0031] Floating structure 4, the floating structure 4 includes a clamping column 45 and clamping arms 47. And there are two groups of clamping arms 47. And the outer surfaces of one end of the clamping column 45 and the two groups of clamping arms 47 are clamped with the outer surface of the rope body 3. The floating structure 4 is used to fix the depth of the collecting cylinder 5 entering the water. The floating structure 4 also includes a housing 41. And inflatable rafts 42 are fixedly connected to the outer surfaces of both sides of the housing 41. And a connecting column 43 and a limiting plate 44 are arranged at one end inside the housing 41. There are two groups of both the connecting column 43 and the limiting plate 44. The clamping column 45 is inserted into the inner surface of the opposite side surfaces of the two groups of limiting plates 44. And a rotating screw 46 is connected to the other end of the clamping column 45 through a bearing. The two groups of clamping arms 47 are respectively sleeved on the outer surfaces of the two groups of connecting columns 43. And rollers 48 are sleeved inside the other ends of the two groups of clamping arms 47. Anti-slip patterns are respectively arranged on the outer surfaces of one end of the clamping column 45 and the two groups of clamping arms 47. And the material of the anti-slip patterns is rubber. A threaded hole is opened inside the surface of the other end of the housing 41. And the inner part of the threaded hole is threadedly connected to the outer surface of the middle position of the rotating screw 46. The shape of the other end of the clamping column 45 is trapezoidal. And the outer surfaces of both sides of the trapezoid are in contact with the outer surfaces of the two groups of rollers 48. According to Figure 6 and Figure 7As shown, when the rotating screw 46 rotates inside the inner surface of one side of the housing 41, it can push the clamping post 45 to move. Then, when the clamping post 45 moves, the outer surfaces on both sides of the trapezoid can push the two groups of rollers 48 and drive the two groups of clamping arms 47 to rotate around the two connecting columns 43 as the centers. At the same time, one ends of the two groups of clamping arms 47 approach each other. This design can clamp the floating structure 4 on the outer surface of the rope body 3.

When the telescopic rod 13 is extended to an appropriate length, pull down the handle 25, drive the pressing post 24 to rotate inside the fixed seat 22 with the fixed column 23 as the center. Then, when the pressing post 24 rotates, it abuts against the upper surface of the pressing block 26. The pressing block 26 moves downward inside the upper end of the fixed ring 21 and abuts against the groove inside the upper surface of the telescopic rod 13, so that the extended length of the telescopic rod 13 is fixed;
[0033] According to the requirement of the collection depth, select an appropriate position on the scale on the outer surface of the rope body 3. Hold the floating structure 4 through the housing 41, and attach the outer surfaces of the clamping post 45 and one ends of the two groups of clamping arms 47 to the outer surface of the rope body 3. Then, rotate the rotating screw 46 inside the inner surface of the other end of the housing 41. Then, one end of the rotating screw 46 pushes the clamping post 45 to move. Then, the clamping post 45 pushes the two groups of rollers 48, so that the two groups of clamping arms 47 rotate around the two connecting columns 43 as the centers respectively, and one ends of the two groups of clamping arms 47 approach each other. Then, the surfaces of the clamping post 45 and one ends of the two groups of clamping arms 47 are clamped on the outer surface of the rope body 3;
[0034] Hold the device by the handle 11, align the collection cylinder 5 with an appropriate water source position, lower the rope body 3 inside the three connecting rings 14, so that the collection cylinder 5 enters the water source. When the two inflatable rafts 42 contact the water surface, they float on the water surface due to buoyancy, restricting the descending depth of the collection cylinder 5. After the sampling is completed, pull the rope body 3 inside the three connecting rings 14, so that the collection cylinder 5 is separated from the water source. Tilt the collection cylinder 5 to collect the water source inside the collection cylinder 5 in a container. The above is all the working principles of this utility model.
