[0003] Ultrapure water quality monitoring devices include detectors, sampling pumps, and equipment boxes. They are large and heavy, making them inconvenient to carry and move, especially when sampling locations need to be changed frequently. Therefore, a portable ultrapure water quality monitoring device is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the device is bulky and inconvenient to use in frequently changed locations. The invention provides a portable ultrapure water quality monitoring device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a water quality monitoring device for ultrapure water, including a base, a detection frame and an equipment frame;

[0006] The detection frame is connected between the base and the equipment frame, and the detector is fixed to the inner wall with bolts. The equipment frame is equipped with a power supply and controller that work with the detector, and the outer wall is equipped with a display screen.

[0007] After one side of the base is opened, it is sealed with a cover plate. The detection tube is then stored in the cavity of the base by a winding mechanism. One end is detachably connected to the detector, and the other end is connected to a sampling pump. The sampling pump is connected to the sample by opening the cover plate.

[0008] As an improvement, the winding mechanism includes a winding rod, which is vertically rotatable within the base, and the detection tube is wound around the winding rod.

[0009] As an improvement, a turntable is also included, with a groove in the center of the bottom surface of the base, and one end of the winding rod is connected to the turntable located in the groove.

[0010] As an improvement, one end of the detection tube is connected to a connecting hose that extends into the detection frame. After the connecting hose is fitted with the sample inlet of the detector, the ultrapure water sample enters the detection chamber of the detector through the sampling pump, the detection tube and the connecting hose.

[0011] As an improvement, a waste discharge pipe is also included. A waste discharge pipe is installed inside the detection frame. One end of the waste discharge pipe is fitted with the discharge end of the detector, and the other end extends to the outside of the base and is connected to a waste valve.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. The rewinding mechanism and modular layout significantly reduce the space occupied by the equipment, enhance portability, and store the test tube inside the base to avoid external contamination and ensure the accuracy of the test results;

[0014] 2. The design of the waste discharge pipe allows the waste liquid generated during the testing process to be discharged in a centralized manner, avoiding the risk of waste liquid leakage and facilitating the cleaning operation of the entire device. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1

[0023] A water quality monitoring device for ultrapure water, combined with an attached Figure 1 and 3 As shown in Figure 4, the device includes a base 1, a detection frame 2, and an equipment frame 3. The detection frame 2 is connected between the base 1 and the equipment frame 3, and the detector 4 is fixed to the inner wall by bolts. The equipment frame 3 is equipped with a power supply and controller that cooperate with the detector 4, and a display screen 5 is installed on the outer wall. After one side of the base 1 is opened, it is covered by a cover plate 6. The detection tube 7 is stored in the cavity of the base 1 by a winding mechanism. One end is detachably connected to the detector 4, and the other end is connected to a sampling pump 8. The sampling pump 8 is connected to the sample by opening the cover plate 6.

[0024] With the above structure, after opening the cover plate 6, take out the detection tube 7 and bring its sampling pump 8 close to the sample to be tested. Then, the sample is extracted by opening the sampling pump 8 and enters the detector 4 for testing. After the detector 4 tests the ultrapure water, the processing unit in the equipment frame 3 processes it and displays the test results on the display screen 5.

[0025] One end of the detection tube 7 is connected to a connecting hose 12 extending into the detection frame 2. After the connecting hose 12 is fitted with the sample inlet end of the detector 4, the ultrapure water sample enters the detection chamber of the detector 4 through the sampling pump 8, the detection tube 7 and the connecting hose 12. It also includes a waste discharge pipe 13. The detection frame 2 is provided with a waste discharge pipe 13. After one end of the waste discharge pipe 13 is fitted with the discharge end of the detector 4, the other end extends to the outside of the base 1 and is connected to a waste valve 14.

[0026] With the above structure, after the detector 4 is installed in the detection frame 2, the connecting hose 12 is fitted with the sample inlet end of the detector 4, and one end of the waste discharge pipe 13 is fitted with the discharge end of the detector 4. After use, the waste valve 14 is opened to discharge the test sample. At the same time, the detection tube 7 can be connected to clean water to clean the sampling pump 8, the detection tube 7, the connecting hose 12 and the inside of the monitor, so as to ensure the accuracy of subsequent test results.

[0027] Example 2

[0028] Based on Example 1, combined with Appendix Figure 2 As shown, the winding mechanism includes a winding rod 9, which is vertically rotatably mounted in the base 1. The detection tube 7 is wound around the winding rod 9. It also includes a turntable 11. A groove 10 is provided in the center of the bottom surface of the base 1. One end of the winding rod 9 is connected to the turntable 11 located in the groove 10.

[0029] With the above structure, during use, the detection tube 7 can be pulled and continuously released with the help of the winding rod 9 until it is close to the test sample. After the test, the detection tube 7 can be stored by rotating the winding rod 9 through the turntable 11, thereby storing the detection tube 7 into the base 1, reducing the size of the device and reducing the risk of damage to the detection tube 7.

[0030] In a specific implementation of this invention, after the detector 4 is installed inside the detection frame 2, the connecting hose 12 is fitted with the sample inlet end of the detector 4, and at the same time, one end of the waste discharge pipe 13 is fitted with the discharge end of the detector 4.

[0031] After opening the cover plate 6, the detection tube 7 is pulled and continuously released with the help of the winding rod 9, so that its sampling pump 8 is close to the sample to be tested. Then, the sample is extracted by opening the sampling pump 8 and enters the detector 4 for testing. After the detector 4 tests the ultrapure water, the processing unit in the equipment frame 3 processes it and displays the test results on the display screen 5.

[0032] After use, open the waste valve 14 to discharge the test sample. At the same time, connect the test tube 7 to clean water to clean the sampling pump 8, test tube 7, connecting hose 12 and the inside of the monitor to ensure the accuracy of subsequent test results.

[0033] By rotating the take-up rod 9 on the turntable 11, the detection tube 7 can be stored in the base 1, thereby reducing the size of the device and reducing the risk of damage to the detection tube 7.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
