[0002] With the acceleration of urbanization, the dredging and maintenance needs of various pipeline systems are growing, and traditional pipeline dredging technology generally relies on gas (such as compressed air) as a medium for dredging operations. However, such methods have significant limitations. The low density, weak viscosity and compressibility of gas result in insufficient energy transmission efficiency, making it difficult to effectively suspend and push the accumulated material. In addition, existing gas pressure dredgers usually use fixed pressure units, and the upper limit of the pressure is limited by the device structure and operation difficulty, which cannot flexibly expand the pressure parameters according to the working conditions, resulting in insufficient adaptability in complex blockage scenarios. In the pressure relief link, whether the traditional gas pressure dredger is successful or not, it uses an instantaneous pressure relief mechanism (≤1 second), which may cause secondary blockage or rebound of residual accumulated material, affecting the thoroughness of dredging.
