Lifting bridge for collecting garbage on river surface

The invention discloses a lifting bridge for collecting garbage on a river surface. The lifting bridge comprises a bridge body, wherein the bridge body is provided with a passing space with front, back, left and right openings, lifting spaces with downward openings are symmetrically arranged on a left side and a right side of the passing space, a linkage space and a power space are arranged on anupper side wall of the passing space in a bilateral symmetry mode, a left-right opening space is formed in the lower side of the lifting spaces, a transmission space is arranged on the upper side of the lifting spaces, and a transportation space with a downward opening is formed in the right side of the linkage space. The lifting bridge is advantaged in that a problem that a traditional large shipcannot pass through a bridge body is solved, the transportation speed is increased, a method for solving the problem is provided for all regions with different terrains, moreover the bridge is simplein structure, ingenious in
