[0026] The embodiment of the present application provides a water quality sampling device, which effectively solves the technical problem that during the sampling process, if impurities enter the gap and block the gap, it will be difficult to disassemble the filter plate 4.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution in the embodiment of the present application effectively solves the technical problem that, during the sampling process, if impurities enter the gap and block the gap, it will make the removal of the filter plate 4 difficult. The overall idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides a water quality sampling device, which comprises a sampling tube 1, the outside of the sampling tube 1 is rotatably connected to a handle 2, and the inner side of the sampling tube 1 is provided with a filtering mechanism;

[0030] The filtering mechanism comprises a limiting plate 3, a filtering plate 4 and a mounting cylinder 5;

[0031] The limiting plate 3 is fixedly installed on the inner side of the sampling tube 1, the filter plate 4 is placed on the upper surface of the limiting plate 3, and the mounting tube 5 is fixedly installed on the outside of the filter plate 4;

[0032] Threaded holes 6 are provided at both ends of the sampling tube 1 , and a fixing bolt 7 is threadedly connected inside each threaded hole 6 . A fixing block 8 is rotatably connected to one end of each fixing bolt 7 close to the upper surface of the mounting tube 5 .

[0033] By setting the filter plate 4 and cooperating with the fixing block 8, when the staff has finished sampling, the fixing bolt 7 is rotated to make the fixing bolt 7 drive the fixing block 8 away from the top of the installation tube 5. At this time, the installation tube 5 is pulled upward to release the connection between the installation tube 5 and the sampling tube 1. At this time, the material accumulated on the filter plate 4 can be poured out, and the installation tube 5 is installed in the sampling tube 1 after pouring out. At this time, the fixing bolt 7 is rotated to drive the fixing block 8 to move until the fixing block 8 is located on the upper surface of the installation tube 5. At this time, the installation tube 5 is confined in the sampling tube 1, and there are not many gaps between the structures of the fixed filter plate 4, so as not to affect the disassembly and assembly of the filter plate 4, reduce the difficulty of disassembly of the filter installation, and prevent affecting the removal of samples.

[0034] A connection hole 9 is formed on the outside of each fixing block 8, and a connection rod 10 is fixedly mounted on the outside of each fixing bolt 7;

[0035] The connecting rod 10 is rotatably connected to the inside of the connecting hole 9, and the connection between the connecting rod 10 and the connecting hole 9 facilitates the fixing bolt 7 to drive the fixing block 8 to move.

[0036] A cover plate 11 is provided outside the mounting tube 5;

[0037] The cover plate 11 is composed of a cylinder and a U-shaped body, so as to close the installation tube 5 .

[0038] An internal thread 12 is formed on the inner side of the mounting tube 5, and an external thread 13 is formed on the outer side of the cover plate 11;

[0039] The cover plate 11 is threadedly connected to the inner side of the installation tube 5 , so as to facilitate the assembly and disassembly of the cover plate 11 .

[0040] The outside of the handle 2 is fixedly connected with a connecting rope 14;

[0041] The other end of the connecting rope 14 is fixedly connected with a mounting ring 15, so that the staff can throw the sampling tube 1 to a distant place for sampling.

[0042] The inner side of the mounting ring 15 is movably connected with a fixing screw 16;

[0043] Among them, the fixing screw 16 is threadedly connected to the outside of the handle 2. When the connecting rope 14 is not in use, the connecting rope 14 is wrapped around the outside of the handle 2, and then the mounting ring 15 is put on the outside of the fixing screw 16. At this time, the fixing screw 16 is connected to the outside of the handle 2 to fix the connecting rope 14.

[0044] By setting the cover plate 11 and cooperating with the external thread 13, when sampling, the cover plate 11 is rotated to release the threaded connection between the external thread 13 and the internal thread 12, and sampling can be carried out at this time. After sampling is completed, the cover plate 11 is fixed to the inner side of the mounting tube 5 through the external thread 13 and the internal thread 12. At this time, the cover plate 11 is pulled upward to drive the mounting tube 5 to release the connection between the mounting tube 5 and the sampling tube 1. At this time, the connection between the cover plate 11 and the mounting tube 5 can be released to pour out the impurities. After pouring out, the cover plate 11 is connected to the mounting tube 5 again. At this time, the mounting tube 5 is reset and fixed in the sampling tube 1 to avoid impurities from contaminating the hands of the staff during the process of pulling the mounting tube 5. At the same time, the cover plate 11 closes the mounting tube 5 to avoid the sample flowing out of the sampling tube 1 due to bumps when carrying the sampling tube 1, resulting in sampling failure.

[0045] Working principle:

[0046] The first step is to rotate the cover plate 11 to release the threaded connection between the external thread 13 and the internal thread 12 when sampling. Then sampling can be performed. After sampling is completed, the cover plate 11 is fixed to the inner side of the mounting tube 5 through the external thread 13 and the internal thread 12. At this time, the fixing bolt 7 is rotated to make the fixing bolt 7 drive the fixing block 8 away from the top of the mounting tube 5. At this time, the cover plate 11 is pulled upward to drive the mounting tube 5 to release the connection between the mounting tube 5 and the sampling tube 1. At this time, the connection between the cover plate 11 and the mounting tube 5 can be released to pour out the impurities.

[0047] In the second step, after the impurities are poured out, the cover plate 11 is connected to the mounting tube 5, and the mounting tube 5 is reset and fixed in the sampling tube 1. At this time, the fixing bolt 7 is rotated to drive the fixing block 8 to move until the fixing block 8 is located on the upper surface of the mounting tube 5. At this time, the mounting tube 5 is confined in the sampling tube 1, and the cover plate 11 seals the mounting tube 5 to prevent the sample from flowing out of the sampling tube 1 due to bumps when carrying the sampling tube 1, resulting in sampling failure.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
