[0002] Reverse osmosis membrane elements are widely used in pure water treatment, water for the pharmaceutical industry, seawater desalination, sewage treatment, cooling tower feed water, boiler feed water, bioengineering, environmental protection engineering and other fields. After a period of operation, pollutants are easily deposited on the reverse osmosis membrane elements, affecting the purification effect. Therefore, during use, maintenance cleaning is required, but due to the deterioration of water quality, the cleaning frequency of the reverse osmosis membrane will also increase, so a cleaning device is needed for cleaning.

[0004] Although the above-mentioned prior art realizes the cleaning of the reverse osmosis membrane, in actual use, the above-mentioned prior art still has the following shortcomings: the device supplies water to the inside of the device through the upper water pipe to flush the internal reverse osmosis membrane, but since the position of the reverse osmosis membrane is fixed, it is impossible to flush all parts of the osmosis membrane, thereby reducing the cleaning efficiency of the reverse osmosis membrane, and it is impossible to clean all parts of the reverse osmosis membrane. The degree of intelligence is low and the cleaning effect is not good. In view of this, we propose an intelligent cleaning reverse osmosis membrane device to solve the above problems.
