    The invention relates to wind energy and can be used to secure the blades of a large diameter wind turbine / bin rotor.
    A retaining device for the rotor blade of a large-diameter wind turbine is known, which contains an inner rod with a hollow cylindrical shank, a cylindrical metal sleeve protruding inward beyond the inner edge of the shank and a cylindrical metal box. installed with emphasis in the outer periphery of the shanks connecting bolts L o
    However, in such a holding device, the rod is combined with the mechanism for adjusting the inclination of the blades, as a result of which the device absorbs considerable loads.
    The aim of the invention is to evenly distribute the load.
    The goal is achieved by the fact that in a holding device for the rotor blade of a large-diameter wind turbine containing an inner rod with a hollow cylindrical shank, a cylindrical metal sleeve protruding inward beyond the inner edge of the shank, a cylindrical metal sleeve installed with an emphasis on the outer periphery of the shank, and connecting bolts, the latter located on the periphery of the shank, and each of them is installed radially, the passage through the sleeves and shank, while one of the sleeves has φ. An 11-pin with an emphasis on another sleeve, adjacent to the inner edge of the shank, and sleeves in the flange zone are connected by a second row of radially mounted bolts.
    The device also contains an intermediate connecting element with a circular end flange and a third row of bolts located in the flange of the connecting element and the flange of one of the sleeves.
    In the device, at least one of the bolts of the third row is made in the form of a pressed-in stud.
    In addition, the bar of the blade is made of a composite material with fiber winding.
    In the device, the shanks on the side of the sleeves are made in the form of a truncated cone with a smaller base with. side flange.

    FIG. 1 shows a section of a wind tunnel along a holding device Oz in FIG. 2, a section A-A in FIG. 1 shows.
    The holding device for the rotor blade of a large-diameter wind turbine contains an inner rod 1 with a hollow cylindrical shank 2 "cylindrical metal sleeve Sj protruding inward beyond
    The outer edge of the shank 2, the cylindrical metal sleeve Dd installed with emphasis in the outer periphery of the shank 2, and the connecting bolts 5o Bolts 5 are located on the periphery of the coaxial 2 and are installed radially through the sleeve 3 and 4 and the shank 2s at the same time 4 has a flange 6 with emphasis in another sleeve 3;
    adjacent to the inner edge of the carrier, and both sleeves 3 and 4 in area 6 are connected by a second row of radially mounted bolts 7 "The device contains an intermediate
    connecting element 8 with a round end flange 9 and the third row of bolts 10, placed in the flange 9 of the connecting element 8 and the flange of the sleeve 3 "
    In the device, at least one of the bolts 10 of the third row is made in the form of a pressed-in pin 11. The bar of the blade in the device is made of a composite material with
    winding fiber.
    The shanks 2 from the side of the sleeves 3 and 4 are made in the form of a truncated cone with a smaller base from the side of the flange 6 o
    In the holding device for
    The rotor blades of the large-diameter wind turbine of the liner are used as part of the core on which fiberglass is wound, then on
    The surface of the liner is applied with epoxy adhesive, the required thickness is achieved by laying layers of fibrous fabric. The bar thus obtained is vulcanized at room temperature.
    temperature within 48 hours, so that the material in the retention area of the rod can be processed.
    During operation of the wind turbine, the retention of the blade is ensured by the efforts
    created by the blade on the y; gerzhirayuschey device.
    The cutting forces extend from the shank to sleeves 3 and 4 of the communication connection.
    neKjv / them fuutTW 7, pos. to the connecter e / hemsig 8, the boita 10. In addition to Toio, the load is perceived by the Oolt 5, due to which the restraint of the restraint is sufficiently large.
    Thus, with such a vortex holding device for the rotor blade of a large-diameter wind turbine, the loads across the connecting elements are evenly distributed.
