A three-scraper wiper blade hydraulic windscreen wiper with flexible wall supporting comprises a windscreen wiper motor, a wiper driving mechanism and a wiper and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe, torque is transmitted between the two blade swing oil cylinders through the hydraulic oil pipe, and a forward and reverse rotation gear intermittent transmission mechanism is arranged on the driving blade swing oil cylinder. The three-scraper wiper blade hydraulic windscreen wiper has the advantages that as flexible pipeline hydraulic transmission is adopted in the wiper driving mechanism of the windscreen wiper, the transmitted torque is large, and structural limit is small when the windscreen wiper is installed; as the windscreen wiper is of a completely closed structure, the windscreen wiper is particularly suitable for the complex external environmental structure and long-distance transmission and not affected by external factors, and the defect that the windscreen wiper motor is burnt due to external obstacles is overcome; windscreen wiper rubber strips are supported by flexible walls and therefore can fit windscreen better, and the scraping efficiency of the three-scraper structure is three times that of a general single scraper.
