[0032] Example 1

[0033] Reference Figure 1 A positioning water quality sampler includes a telescopic rod 1, a sampler body 2, a water inlet part 3 and a water storage part 4. The water inlet part 2, the water storage part 3 and the telescopic rod 1 are connected as a whole through the sampler body 2, wherein the telescopic rod 1 is installed on the right side of the sampler body 2, and the length of the telescopic rod 1 can be extended, and the sampler body 2 can be extended to the required position of the pipeline. The water inlet part 3 is detachably installed on one side wall of the sampler body 2, and the water storage part 4 is detachably installed on the other side wall of the sampler body 2.

[0034] For ease of understanding and description, the left and right directions mentioned above are all in Figure 1 It should be understood that this orientation is only set for the convenience of description and understanding, and cannot be understood as a limitation of the present invention.

[0035] Reference Figure 3 and Figure 4 The telescopic rod 1 includes three sleeve rods 14 with different inner diameters, wherein the sleeve rod 14 with a small diameter is installed inside the sleeve rod 14 with a large diameter, and then the two can be fixed by a limiting clamp, which includes a U-shaped clamping plate. The U-shaped clamping plate is sleeved on the end of each sleeve rod 14, and the two slidable sleeve rods can be fixed by bolts.

[0036] Further, the two ends of the telescopic rod 1 are respectively connected to the lower connecting member 15 and the upper connecting member 13, wherein the upper connecting member 13 is installed with an upper connecting nut 11, and the upper connecting nut 11 is used to thread the extension rod 5, and the lower connecting member 15 can be threadedly connected to the sampler body 2 through the lower connecting nut 16;

[0037] Furthermore, a chain 12 is laterally passed through the interior of the telescopic rod 1 (see Figure 3 and Figure 4 ), wherein both ends of the chain 12 can extend out of the lower connecting piece 15 and the upper connecting piece 13 respectively, and both ends of the chain 12 are provided with pull rings, which are respectively used to connect the blocking slider 21 in the sampler body 2 and the chain in the extension rod 5.

[0038] Reference Figure 5and Figure 6 The sampler body 2 includes a blocking slider 21, a water inlet connection port 22, a water outlet connection port 23, a connection buckle 24 and a sampler cover 25. It should be noted that the sampler body 2 is a rectangular frame structure, and the interior is hollow, and the upper and lower openings (the upper and lower directions refer to Figure 5 or Figure 6 ) are detachably connected to the sampler cover 25 by bolts, and a slidable blocking slider 21 is provided inside the sampler body 2, and a connecting buckle 24 is provided on the top of the blocking slider 21, wherein the connecting buckle 24 is a rod-shaped structure, and its top can penetrate the sampler cover 25 and be connected to the pull ring on the chain 12, so that the blocking slider 21 can be pulled by the chain 12 to slide inside the sampler body 2;

[0039] Further, a water inlet connection port 22 is provided at a lower position of one of the side walls of the sampler body 2, and the water inlet connection port 22 is used to connect the water inlet member 3, and a water outlet connection port 23 is provided at a lower position of the other side wall of the sampler body 2, and the water outlet connection port 23 is used to connect the water storage member 4. Under normal circumstances, the blocking slider 21 is blocked inside the sampler body 2, so the water inlet member 3 and the water storage member 4 are not connected;

[0040] It should be noted that the height of the blocking slider 21 is less than or equal to 1 / 2 of the sampler body 2, so when the chain 12 pulls the blocking slider 21 upward (here, the height of the blocking slider 21 is only 1 / 2 of the sampler body 2).

[0043] Example 2

[0044] Reference Figure 1 On the basis of Example 1, according to the actual size of the pipeline to be detected, the user can add an extension rod 5 as needed. The extension rod 5 has the same structure as the telescopic rod 1, and the extension rod 5 is also telescopic. The chain in the extension rod 15 is first connected to the chain 12 in the telescopic rod 1, and then the lower connecting piece on the extension rod 15 is detachably connected to the upper connecting piece 13 on the telescopic rod 1 through the upper connecting nut 11. Similarly, if the length of the extension rod 15 is not enough, another extension rod can be added on the basis of the extension rod 15, and so on.

[0045] The specific operating principles of this application are as follows:

[0046] When in use, the sampling personnel need to put it into the inspection well, and adjust the length of the telescopic rod 1 according to the depth of the drainage pipe, and send the water inlet 3, the water storage part 4 and the cross bar 31 into the pipe mouth to be sampled; use the cross bar 31 to tightly hook the top of the pipe, and record the scale reading of the telescopic rod 1 at the inspection well mouth at this time; pull the sealing slider 21 upward through the pull ring to form a passage between the water inlet 3 and the water storage part 4, and the water sample automatically enters the sampling bottle 41 under the action of water pressure, so as to realize the water sample collection at a specific position, that is, to achieve "first positioning, then sampling" of the water sample in the pipeline.

[0047] In the above process, it is necessary to ensure that the sewage flows to the water inlet pipe 32 , the sewage flows into the water inlet pipe 32 through the grid, and then flows into the sampling bottle 41 through the sampler body 2 .

[0048] After recording the scale reading of the telescopic rod 1 at the inspection well mouth at the same time, the telescopic rod 1 can be moved downward to adjust the sampling position and take water. The sampling position at this time can be determined by simply recording the scale reading of the telescopic rod 1 at the inspection well mouth at this time.
