[0002] During use, reverse osmosis membrane elements require regular testing of the water quality to determine whether they need cleaning or replacement. Existing reverse osmosis membrane element water quality testing primarily relies on manual testing, where operators manually insert a test tube into the membrane element to take a sample, then send the sample to testing equipment for analysis.

[0003] This manual testing method has multiple problems: the testing process requires continuous manual operation, which is labor-intensive and has low testing efficiency; the depth and position of the manually inserted test tube are difficult to accurately control, affecting the accuracy of sampling; the sealing between the test tube and the membrane element is poor, which easily causes water sample contamination; water samples often overflow during the sampling process, causing pollution to the testing environment.

[0004] Furthermore, existing testing equipment is bulky and difficult to move, and the connections between components are illogical, which can easily lead to leakage. Recording and analyzing test data also requires manual effort, which is prone to errors and inefficient. These issues severely impact the effectiveness of reverse osmosis membrane element testing and maintenance. Utility Model Content

The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0044] Specifically, the turntable 21 is provided with a central channel; the sampling hose 22 is arranged on the turntable 21, and one end thereof extends into the central channel; the feeding device is arranged on the outer periphery of the sampling hose 22 and abuts against it, and is used to control the feeding of the sampling hose 22; one end of the connecting pipe 24 is connected to the central channel, and the other end is connected to the water quality analysis device 25.

[0045] The sampling hose 22 is made of a flexible material, which is easy to bend and deform, and can adapt to the requirements of different detection positions.

[0046] In this embodiment, the feeding device includes a feeding wheel 231 and a stepper motor 232. Specifically, the feeding wheel 231 is disposed on the outer periphery of the sampling hose 22 and abuts against it; the stepper motor 232 is connected to the feeding wheel 231 to drive the feeding wheel 231 to rotate. The speed of the stepper motor 232 can be adjusted according to actual needs to achieve precise feeding control of the sampling hose 22.

[0047] In one embodiment, a control valve 26 is further included to control the flow of the water sample. Specifically, the control valve 26 is disposed on the connecting pipe 24 .

[0048] In a specific example, the water quality analysis device 25 includes a detection probe 251, an analytical instrument 252, a water tank 253, a drain pipe 254, and a drain valve 255. Specifically, the detection probe 251 is connected to the other end of the connecting pipe 24 and is used to detect various parameters of the water sample. The analytical instrument 252 is mounted on the detection probe 251 and is used to display and record the detection data. The analytical instrument 252 is conventional, and the analysis process performed using the analytical instrument 252 is also conventional. The detection probe 251 is connected to the water tank 253 via a connecting pipe. The drain pipe 254 has one end connected to the water tank 253 and the other end extending outside the water quality analysis device 25 to facilitate wastewater discharge. The drain valve 255 is mounted on the drain pipe 254 to control drainage. The detection probe 251 in this embodiment can be of different types, such as a conductivity probe, a pH probe, etc., depending on actual needs. The detection probe 251 is connected to the water tank 253 through a connecting pipe and is used to temporarily store water samples after detection.

[0049] Those skilled in the art will appreciate that the type of the drain valve 255 can be selected according to actual needs, such as a ball valve, a butterfly valve, etc.

[0050] In addition, this embodiment further includes a housing 27 for accommodating the turntable 21, the feed device, the connecting pipe 24, and the water quality analysis device 25. Specifically, the other end of the sampling hose 22 extends outside the housing 27 to facilitate insertion of the membrane element to be tested, for example, through the reverse osmosis membrane housing end cap 105 and into the integrated reverse osmosis water production connector. The other end of the drain pipe 254 extends outside the housing 27 to facilitate wastewater discharge.

[0051] In order to improve the mobility of the device, this embodiment further includes universal wheels 28. Specifically, the universal wheels 28 are arranged at the bottom of the chassis 27.

The material of the sealing ring 29 can be selected based on actual needs, such as rubber or polytetrafluoroethylene. The connecting pipe 24 is connected to the water quality analysis device 25 via a pipe clamp 241 to ensure a stable connection.

[0054] In this embodiment, the connecting pipe 24 can be connected to the water quality analysis device 25 via a pipe clamp 241 .

It is known to those skilled in the art that the material of the connecting pipe 24 can also include other corrosion-resistant materials, such as engineering plastics, etc., which can be set according to actual needs.

[0056] In this embodiment, when working, the sampling hose 22 is first inserted into the membrane element to be tested (for example, it can pass through the integrated reverse osmosis water production connector and the reverse osmosis membrane shell end cover 105 in sequence to enter the membrane element to be tested; or directly pass through the reverse osmosis membrane shell end cover to enter the membrane element to be tested), and the stepper motor 232 is controlled to operate through the display panel 271, driving the feed wheel 231 to rotate, thereby achieving precise feeding of the sampling hose 22. Open the control valve 26, and the water sample flows into the detection probe 251 through the sampling hose 22, the central channel and the connecting pipe 24, and the detection data is displayed by the analyzer 252. After the test is completed, the water sample flows into the water tank 253 (for example, it can be stored in the water tank 253 first), and finally discharged through the drain pipe 254. The whole process has a high degree of automation, which can improve the detection efficiency and accuracy.

[0057] In summary, the reverse osmosis membrane element detection device proposed in this utility model has the following advantages:

[0058] Through the coordinated structure of the turntable, sampling hose, feeding device and connecting pipe, accurate feeding of the sampling hose and effective collection of water samples can be achieved. Combined with the detection function of the water quality analysis device, the detection process of the RO reverse osmosis membrane element can be automatically completed, thereby improving the detection efficiency and accuracy.
