DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , a metering and detection device for measuring liquid, comprising a base 1, a water tank 2 is fixedly mounted on the base 1, a sampling bucket 3 is fixedly mounted on the side wall of the water tank 2, a water inlet hole connected to the water tank 2 is opened on the inner wall of the sampling bucket 3, a blocking component is provided at the water inlet, the blocking component comprises a U-shaped frame 9 fixedly mounted in the sampling bucket 3, a rectangular plate 10 slidably mounted between the U-shaped frame 9 and the inner wall of the sampling bucket 3, and a locking component for locking the rectangular plate 10, the surface of the rectangular plate 10 is in sliding contact with the inner wall of the sampling bucket 3, a rectangular opening is opened on the side wall of the limiting plate 7, the rectangular plate 10 is slidably inserted in the rectangular opening, the locking component comprises a spring rod 11 fixedly mounted on the water tank 2 horizontally and a U-shaped rod 12 fixedly mounted at one end of the spring rod 11, two positioning holes are opened on the rectangular plate 10, and the vertical spacing of the two ends of the U-shaped rod 12 is equal to the vertical spacing of the two positioning holes;

[0024] When the lower end of the U-shaped rod 12 is inserted into the upper positioning hole of the two positioning holes opened on the rectangular plate 10, the lower end of the rectangular plate 10 just contacts the bottom wall of the sampling bucket 3, thereby blocking the water inlet hole. When the rectangular plate 10 is driven to move vertically upward and the two ends of the U-shaped rod 12 are respectively inserted into the two positioning holes, the rectangular plate 10 will be separated from the water inlet hole. At this time, the liquid in the water tank 2 will pass through the water inlet hole and enter the sampling bucket 3.

[0025] A U-shaped support frame 4 is fixedly installed on the water tank 2, and a threaded hole is opened on the support frame 4, and a threaded rod 5 is inserted into the threaded hole. An adjusting block 6 is fixedly installed on the upper end of the threaded rod 5, and a limit plate 7 is rotatably installed on the lower end. The limit plate 7 is slidably inserted in the sampling barrel 3, and the side wall of the limit plate 7 is in close contact with the inner wall of the sampling barrel 3;

[0026] The threaded rod 5 can be driven to rotate by rotating the adjusting block 6, and then the threaded rod 5 can be driven to move vertically up and down through the threaded hole provided on the supporting frame 4, and then the limiting plate 7 can be driven to move up and down in the sampling barrel 3 through the threaded rod 5. The side wall of the limiting plate 7 is in airtight contact with the inner wall of the sampling barrel 3, so that the sampling volume of the sampling barrel 3 can be adjusted by the height of the limiting plate 7 in the sampling barrel 3, and the amount of liquid sampled each time can be adjusted. When sampling, there is no need for the operator to observe with the eyes, so the accuracy of the amount of liquid sampled each time is guaranteed, thereby improving the accuracy of the detection structure.

[0027] A detector 8 is fixedly installed on the base 1 (the detector 8 is a prior art and will not be introduced in detail here), a water outlet pipe is fixedly connected to the sampling barrel 3, a visual window is installed on the sampling barrel 3, a scale is engraved on the visual window, and a control valve is installed on the water outlet pipe. It only needs to open the control valve and add the liquid in the sampling barrel 3 to the detector 8 through the water outlet pipe, and the detection result can be analyzed by the detector 8.

[0028] The limiting plate 7 is symmetrically provided with moving holes, and moving rods 13 are vertically slidably inserted in the two moving holes. Push plates 14 are fixedly installed at the lower ends of the two moving rods 13, and the upper surface of the push plate 14 contacts the lower surface of the limiting plate 7. An elastic component for driving the push plate 14 to move upward is provided on the limiting plate 7. The elastic component includes a connecting block 15 fixedly installed at the upper ends of the two moving rods 13 and two telescopic springs 16 respectively sleeved on the two moving rods 13. A circular hole is provided on the connecting block 15, and the threaded rod 5 is inserted in the circular hole. The two ends of the telescopic spring 16 are respectively fixedly connected to the connecting block 15 and the limiting plate 7;

[0029] Under the action of the elastic force of the telescopic spring 16, the moving rod 13 drives the push plate 14 to move vertically upward, so that the upper surface of the push plate 14 fits together with the lower surface of the limiting plate 7. When opening the control valve, it is only necessary to push the connecting block 15 downward to drive the two moving rods 13 to move vertically downward, and then drive the push plate 14 to move vertically downward through the two moving rods 13. The telescopic spring 16 is compressed, and the push plate 14 is used to scrape the residual liquid on the inner wall of the sampling barrel 3 and squeeze it out of the sampling barrel 3 to prevent the liquid from remaining on the inner wall of the sampling barrel 3, thereby ensuring that the actual liquid intake is the same as the required liquid intake.

[0030] A sealing gasket is fixedly installed on the lower surface of the push plate 14. The sealing gasket is made of rubber. The sealing gasket can reduce the gap between the side wall of the push plate 14 and the inner wall of the sampling barrel 3, so as to scrape the residual liquid on the inner wall of the sampling barrel 3 more cleanly.

[0031] In the utility model, the threaded rod 5 can be driven to rotate by rotating the adjustment block 6, and the threaded rod 5 can be driven to move vertically up and down, and then the threaded rod 5 can drive the limiting plate 7 to move up and down in the sampling barrel 3. The sampling volume of the sampling barrel 3 can be adjusted by the height of the limiting plate 7 in the sampling barrel 3, and the amount of liquid sampled each time can be adjusted. When sampling, the operator does not need to observe with his eyes, so the accuracy of the liquid sampled each time is guaranteed, thereby improving the accuracy of the detection structure.

[0032] In general, in response to the technical problem: manual extraction is required during sampling, and real-time observation can only be performed through visual observation during extraction, and the amount of liquid taken cannot be flexibly adjusted, which can easily cause inaccurate liquid amount, thus affecting the test results; a technical solution is adopted: the internal space size of the sampling barrel 3 is adjusted through the cooperation of the sampling barrel 3, the support frame 4, the threaded rod 5, the adjustment block 6 and the limit plate 7; because the implementation process of the technical solution is: the threaded rod 5 can be driven to rotate by rotating the adjustment block 6, and the threaded rod 5 can be driven to move vertically up and down, and then the limit plate 7 can be driven by the threaded rod 5 to move up and down in the sampling barrel 3, and the sampling volume of the sampling barrel 3 can be adjusted by the height of the limit plate 7 in the sampling barrel 3, and the amount of liquid sampled each time can be adjusted; so the technical problem can definitely be solved, and the technical effect achieved is: there is no need for the operator to observe with the eyes, and the accuracy of the amount of liquid taken each time is guaranteed, thereby improving the accuracy of the detection structure.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
