Detailed Implementation

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-7 As shown, a sampling device for wastewater treatment testing includes: a vertical rod 1, four sampling tubes 101 arranged on the outside of the vertical rod 1, and an installation assembly between the sampling tubes 101 and the vertical rod 1 for fixing the sampling tubes 101. The installation assembly includes: a mounting block 2, a threaded hole 201, a through hole 202 and a threaded rod 203. A water inlet assembly is provided at the bottom of the sampling tubes 101 for allowing wastewater to enter the sampling tubes 101. The water inlet assembly includes: a detachable cover 4, a water inlet hole 401, a movable rod 402 and a movable hole 403.

[0023] Each of the four sampling tubes 101 has a mounting block 2 connected to one side of its outer end. The mounting block 2 has a threaded hole 201 on its inner side, and the vertical rod 1 has multiple through holes 202 on its outer side. A threaded rod 203 is threadedly connected inside the threaded hole 201. When it is necessary to install the sampling tube 101 on the outer side of the vertical rod 1, the sampling tube 101 and the mounting block 2 are placed on one side of the vertical rod 1, and the threaded hole 201 is aligned with one of the through holes 202. Then, one end of the threaded rod 203 is passed through the through hole 302 and the through hole 202 and turned into the threaded hole 201 and threadedly connected to the threaded hole 201. At this time, the sampling tube 101 and the mounting block 2 can be fixed on one side of the vertical rod 1. Through the multiple through holes 202 of different heights, the sampling tube 101 can be fixed at different heights on one side of the vertical rod 1. According to the sampling requirements, it is possible to choose whether to install all four sampling tubes 101 on the outer side of the vertical rod 1. When all four sampling tubes 101 are installed, they need to be installed on one side of the vertical rod 1 respectively.

[0024] The vertical rod 1 is connected to four sliders 3 on all four sides, and two sliding plates 301 are connected to the inner side of each of the four mounting blocks 2. The eight sliding plates 301 are located on both sides of the four sliders 3. A through hole 302 is opened on one side of the outer end of each of the four sliders 3. When the sampling tube 101 and the mounting block 2 are installed on the outside of the vertical rod 1, since the vertical rod 1 is equipped with sliders 3 on all four sides, the mounting block 2 can slide on the outside of the sliders 3 through the sliding plates 301, thereby positioning the mounting block 2 and facilitating the fixed installation of the mounting block 2.

[0025] Each of the four sampling tubes 101 has a disassembly cover 4 at its bottom. A water inlet 401 is provided on one side of the bottom of the disassembly cover 4. A movable rod 402 is provided inside the water inlet 401. A movable hole 403 is provided on one side of the top of the sampling tube 101. When the sampling tube 101 is placed in sewage and sampling is required, the movable rod 402 is moved upward by the lifting block 601 until the bottom end of the movable rod 402 slides out from inside the water inlet 401. At this time, sewage can enter the sampling tube 101 from the water inlet 401. After the sewage is sampled, the bottom end of the movable rod 402 is inserted into the water inlet 401 to block the water inlet 401. The movable hole 403 allows the movable rod 402 to pass through the sampling tube 101, ensuring the mobility of the movable rod 402. Both the movable hole 403 and the water inlet 401 are piston-connected to the movable rod 402, thereby preventing sewage in the sampling tube 101 from leaking from the water inlet 401 and the movable hole 403.

[0026] The movable rod 402 is connected to a metal plate 5 with a circular structure on the outside, and a magnetic plate 501 with a circular structure is connected to the top of the disassembly cover 4. The magnetic plate 501 and the metal plate 5 are magnetically attracted to each other. The top of the disassembly cover 4 is connected to a connecting ring 502, and the outer side of the connecting ring 502 is threaded to the inner wall of the sampling cylinder 101. When the bottom end of the movable rod 402 is reinserted into the water inlet 401, it is ensured that the movable rod 402 drives the metal plate 5 to stick together with the magnetic plate 501 and attracts them magnetically, thereby fixing the position of the movable rod 402.

[0027] The movable rod 402 has a disassembly hole 6 at its top and a lifting block 601 at its top. The bottom of the lifting block 601 is connected to the disassembly rod 602, which is threaded to the disassembly hole 6. When it is necessary to clean the inside of the sampling tube 101, the movable rod 402 is moved to separate the metal plate 5 from the magnet plate 501. Then, the disassembly cover 4 is rotated to drive the connecting ring 502 to rotate until the connecting ring 502 is separated from the sampling tube 101. At this time, it is convenient to clean the inside of the sampling tube 101. The lifting block 601 can be rotated to drive the disassembly rod 602 to be removed from the disassembly hole 6. At this time, the movable rod 402 can be separated from the sampling tube 101.

[0028] The top of the vertical rod 1 is connected to a top plate 7, and the top of the top plate 7 is connected to a handle 701. When using the device, the staff uses the handle 701 to sink the vertical rod 1 and the sampling tube 101 into the sewage. Then, multiple movable rods 402 are used to control multiple sampling tubes 101 to sample the sewage. The top plate 7 is used to install the handle 701 on the top of the vertical rod 1.

[0029] Working principle:

[0030] When using this device, place the sampling tube 101 and mounting block 2 on one side of the vertical rod 1, align the threaded hole 201 with one of the through holes 202, and then pass one end of the threaded rod 203 through the through hole 302 and the through hole 202 into the threaded hole 201 for threaded connection. At this point, the sampling tube 101 and mounting block 2 can be fixed to one side of the vertical rod 1. Through the multiple through holes 202 at different heights, the sampling tube 101 can be fixed at different heights on one side of the vertical rod 1. Furthermore, depending on the sampling requirements, it can be selected whether all four sampling tubes 101 are installed on the outside of the vertical rod 1. When installing all four sampling tubes 101, install them on one side of the vertical rod 1. Then, the staff uses the handle 701 to submerge the vertical rod 1 and the sampling tubes 101 into the sewage. Then, the staff uses the lifting block 601 to move the movable rod 402 upward until the bottom of the movable rod 402 slides out from the inlet hole 401. At this time, the sewage can enter the sampling tube 101 from the inlet hole 401. After the sewage is sampled, the bottom of the movable rod 402 is inserted into the inlet hole 401 to block the inlet hole 401. Then, the staff uses the handle 701 to lift the vertical rod 1 and the sampling tubes 101 out of the sewage.
