The present invention relates to a modular wind power blade tangential partition connection structure. A blade body comprises a windward side (1) and a leeward side (2); and a front edge housing (3) and a rear edge housing (2) which are formed by skins of the windward side (1) and the leeward side (2) in the tangential direction of the blade. Spar caps (5) are arranged on the windward side (1) and the leeward side (2). A shear web (6) is arranged in the cavity of the blade body, extends between the windward side (1) and the leeward side (2), and is used for supporting the spar caps (5). The spar caps (5) located on the windward side (1) and the leeward side (2) are bonded and fixed to the skin structure at the connection positions of the front edge housing (3) and the rear edge housing (4), so that the front edge housing (3) and the rear edge housing (4) are connected to the spar caps (5) to form a wind power blade contour. Compared with existing connection modes, the bonding structure at the skin structure i
