The application relates to the technical field of wind turbine units, and particularly provides a blade deformation rapid evaluation method and system, an electronic device and a storage medium, and aims to solve the technical problems of a complex calculation process and a long time consumption of an existing method. To this end, the blade deformation rapid evaluation method comprises the following steps: acquiring a previously constructed aeroelastic model and a tip loss coefficient database; constructing a first mapping relationship based on the aeroelastic model and the tip loss coefficient database, wherein the first mapping relationship represents a linear response relationship between a blade deformation amount and aerodynamic force; constructing a second mapping relationship based on the aeroelastic model and the tip loss coefficient database, wherein the second mapping relationship represents a linear response relationship between the aerodynamic force and the blade deformation amount; and determining a blade deformation evaluation result based on the first mapping relationship and the second mapping relationship. The application can rapidly evaluate the deformation of a blade under different wind speed conditions, and effectively reduces the calculation amount.

This application relates to a folding and sewing method, a folding device, and a bag-attaching machine. The folding and sewing method uses a folding device to sew a fabric bag and includes the following steps: a tongue-pressing plate is placed on the worktable; a tongue-pressing plate driver drives the tongue-pressing plate to extend outward and places the bag on the tongue-pressing plate; a bracket driver drives a mounting bracket to move towards the tongue-pressing plate; when the tongue-pressing plate contacts an elastic body, the mounting bracket stops moving; a magnet driver drives a magnetic suction component to move towards the tongue-pressing plate; when the magnetic suction component passes through a perforated hole and is magnetically attracted to the bag and the tongue-pressing plate, the magnet driver drives the tongue-pressing plate to press against the elastic body, causing the tongue-pressing plate to be recessed into the elastic body. The folding and sewing method, folding device, and bag-attaching machine provided by this application solve the problem of high manufacturing costs caused by the need to frequently change the concave mold when changing bag styles.

The utility model relates to the technical field of earphones, in particular to a self-adaptive springback earphone and an earphone module. The self-adaptive springback earphone comprises an earphone body, an air bag and an adjusting assembly, the air bag is connected with the earphone body, the side, away from the earphone body, of the air bag is used for being attached to the ear contour, an air bag cavity is formed in the side, close to the earphone body, of the air bag, and the adjusting assembly comprises a main exhaust groove which is formed in the side, close to the earphone body, of the air bag. The first end of the main exhaust groove is located in the air bag cavity, and the second end of the main exhaust groove communicates with the outside so that the air bag cavity can communicate with the outside. By applying the technical scheme of the invention, the air bag can realize rapid self-adaptive rebound, so that the air bag can be stably attached to the ear contour in various use scenes, and the wearing comfort and stability of the earphone are further improved.

The invention discloses a connector technology, and aims to provide a four-core beam-expanding oil-filled optical fiber connector and an assembling method thereof. According to the technical scheme, the oil-filled plug is characterized by comprising a threaded sleeve, a plug shell, a four-optical-fiber beam expanding insulator, a pressure compensator, an oil-filled plug tail clamp, a sealing assembly and a calibration gasket which is clamped between the butt joint end faces of the oil-filled plug tail clamp and the plug shell and used for adjusting the pre-compression stroke of the pressure compensator. The screw sleeve, the plug shell, the four-optical-fiber beam expanding insulator, the pressure compensator, the oil-filled plug tail clamp, the sealing assembly and the calibration gasket jointly define a completely-closed oil-filled cavity, fluorinated oil or synthetic hydrocarbon oil subjected to degassing treatment is injected into the oil-filled cavity through a valve, and the oil-filled cavity is matched with the pressure compensator to construct an active pressure compensation sealing system. The invention is suitable for the technical field of connectors.
