According to Securities Star news, data from the Tianyancha APP shows that China Petroleum & Chemical Corporation (Sinopec) (600028) has recently obtained a new invention patent authorization. The patent is titled “Vortex Disk Wind Collecting Wind Power Generation Device,” with the application number CN202210849964.8, and the authorization date is March 24, 2026.

Patent Abstract: This invention relates to the field of wind power generation technology, specifically to a vortex disk wind collecting wind power generation device. It includes a generator, an impeller, and an overspeed brake device arranged between the two. The outer side of the impeller is equipped with a vortex disk wind collecting device; this device comprises a top vortex disk and a bottom vortex disk that are respectively located at the upper and lower ends of the impeller, with a flow channel partition module arranged between the top and bottom vortex disks. By using streamlined fixed partitions and sliding partitions to adjust the natural wind field, the wind force is applied to the downwind blade section, eliminating the reverse wind resistance loss during the impeller’s rotation and increasing the overall wind energy-to-electricity conversion efficiency by more than 20%.
