A large-size wind power blade having a multi-beam structure. The blade adopts a hollow layout structure and comprises a blade skin suction edge (11), a blade skin pressure edge (12), main load-carrying structure cross beams (1, 2, 4, 5) and anti-shearing webs (7, 8). The blade skin suction edge (11) and the blade skin pressure edge (12) are combined to form a cavity structure having a streamlined section. Both the blade skin suction edge (11) and the blade skin pressure edge (12) adopt a multi-segment combined structure, and the multiple segments are connected to the side surfaces of the main load-carrying cross beams (1, 2, 4, 5) to integrally form the blade skin suction edge (11) and the skin pressure edge (12). According to the large-size wind power blade having the multi-beam structure, high-modulus carbon fiber overlay is used, so the weight of the blade is reduced, the fatigue load of the blade is lowered, and the anti-buckling-instability capability of the blade structure is improved ...
