[0057] 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 .

[0058] In a specific example, the water quality analysis device 25 includes: a detection probe 251, an analysis meter 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 for detecting various parameters of the water sample; the analysis meter 252 is arranged on the detection probe 251 for displaying and recording the detection data.

[0061] In order to improve the mobility of the device, the present embodiment further includes universal wheels 28. Specifically, the universal wheels 28 are arranged at the bottom of the chassis 27.

[0064] In this embodiment, the connecting pipe 24 can be connected to the water quality analysis device 25 via a pipe clamp 241 .

[0065] The connecting pipe 24 may be made of stainless steel, which has good corrosion resistance and mechanical strength. It is known to those skilled in the art that the connecting pipe 24 may also be made of other corrosion-resistant materials, such as engineering plastics, etc., which may be set according to actual needs.

[0066] In this embodiment, when working, first insert the sampling hose 22 into the membrane element to be tested (for example, it can pass through the integrated reverse osmosis water production connector 1 and the reverse osmosis membrane shell end cover 105 in sequence to enter the reverse osmosis membrane element), and control the stepper motor 232 to operate through the display panel 271, driving the feeding wheel 231 to rotate, so as to achieve accurate 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 detection, 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.

[0067] In addition, if Figure 7 As shown, this embodiment also provides a water sample detection method for a reverse osmosis membrane element, using the water sample detection system of the reverse osmosis membrane element as described above, specifically comprising the following steps:

[0068] S1, collecting water samples of the reverse osmosis membrane element in the reverse osmosis membrane shell 100 through the sampling hose 22 of the reverse osmosis membrane element detection device 2;

[0069] S2. Use the water quality analysis device 25 to detect and analyze the water sample and display the detection results.

[0070] In this embodiment, it also includes: driving the feeding device to control the sampling hose 22 to move within the reverse osmosis membrane element according to a preset distance.

[0071] During the sampling process, the sampling hose 22 can be controlled by the feeding device to move within the reverse osmosis membrane element at a preset distance to achieve accurate sampling at different positions. It is known to those skilled in the art that the preset distance can be adjusted according to actual detection requirements to obtain more accurate detection data.

[0072] In a preferred embodiment, the method of this embodiment further includes a step of pre-cleaning the system before sampling. Specifically, a cleaning liquid can be injected into the sampling pipeline and discharged after circulating it for a certain period of time to ensure the cleanliness of the sampling pipeline. It is known to those skilled in the art that the type of cleaning liquid and the cleaning time can be adjusted according to the actual pollution situation.

[0073] In another preferred embodiment, the method of this embodiment further includes the step of adjusting the feeding speed of the sampling hose 22 when sampling at different positions.

[0074] In another preferred embodiment, the method of this embodiment further includes the step of analyzing and processing the detection data.

It can be known to those skilled in the art that the data analysis method can select different algorithms and models according to actual application requirements.

[0075] In this embodiment, first, the sampling hose 22 of the reverse osmosis membrane element detection device 2 is inserted into the reverse osmosis membrane element through the sampling end cover 15 of the integrated reverse osmosis water production connector 1. During the insertion process, the insertion depth of the sampling hose 22 can be accurately controlled by the feeding device. It is known to those skilled in the art that the insertion depth can be adjusted according to actual needs to adapt to reverse osmosis membrane elements of different specifications.

[0076] Secondly, the feeding device is started to control the sampling hose 22 to move within the reverse osmosis membrane element according to a preset distance. Specifically, the stepping motor 232 drives the feeding wheel 231 to rotate, driving the sampling hose 22 to perform feeding movement. It can be known to those skilled in the art that the preset distance can be a fixed interval or a different interval set according to actual detection requirements to achieve focused detection of a specific position.

[0077] Then, after the sampling hose 22 reaches the designated position, the water sample is transported to the water quality analysis device 25 through the central channel of the turntable 21 and the connecting pipe 24. During the transportation process, the representativeness of the water sample can be ensured by controlling the sampling time. It is known to those skilled in the art that the sampling time can be adjusted according to the actual flow rate and detection requirements.

[0078] Next, the water sample is tested and analyzed using the detection probe 251 in the water quality analysis device 25. The detection parameters may include but are not limited to water quality indicators such as pH value, conductivity, turbidity, etc. It is known to those skilled in the art that different types of detection probes 251 may be selected according to actual needs to meet different detection requirements.

[0079] Finally, the detection results are displayed in real time through the display panel 271, and the detection data can be selectively stored. The water sample after the detection is discharged through the water tank 253 and the drain pipe 254, and the drainage speed can be controlled by the drain valve 255. It can be known to those skilled in the art that the data storage format and cycle can be set according to actual application requirements.

[0080] Through the above method, the water quality at different positions inside the reverse osmosis membrane element can be automatically detected and analyzed, the detection efficiency and accuracy can be improved, and important technical support can be provided for the operation and maintenance of the reverse osmosis membrane element.

[0081] In summary, the water sample detection system and method of the reverse osmosis membrane element proposed by the present invention has the following advantages:

[0082] By setting up the structure of reverse osmosis membrane shell, integrated reverse osmosis water production joint and reverse osmosis membrane element detection device, the collection, detection and analysis of water samples inside the reverse osmosis membrane element are realized, and the water quality conditions at various locations inside the reverse osmosis membrane element can be accurately grasped.
