The invention discloses a flood prevention water retaining belt which comprises a first base body, a second base body and a plurality of connecting pieces. In the unfolded state, the second base body is downwards attached to the first base body under the action of gravity, and correspondingly, the connecting piece is folded. In the winding and folding state, the second base body is also attached to the first base body, and correspondingly, the connecting piece is in the folding state. When the flood prevention water retaining belt in the unfolded state is used for retaining water, water enters the position between the first base body and the second base body, the second base body is jacked upwards, namely, the second base body swings around the long edge connected with the first base body, and the connecting piece is also unfolded. The more the water is, the larger the swing amplitude of the second base body is until the connecting piece is straightened, and when the connecting piece is in a tightened state, the angle between the first base body and the second base body is smaller than 90 degrees. Water is blocked through the second base body, after the connecting piece is straightened, a stable triangular structure is formed among the first base body, the second base body and the connecting piece, and water blocking is guaranteed.
本发明公开了一种防汛挡水带，包括第一基体、第二基体和多个连接片。在铺展开状态下，第二基体在重力作用下，向下贴合到第一基体，相应的，连接片就为折叠起来。在卷绕收拢状态下，第二基体也贴合到第一基体，相应的，连接片为折叠状态。当铺展开状态下的防汛挡水带用于挡水时，水进入到第一基体和第二基体之间，将第二基体向上顶起，即第二基体绕着和第一基体连接的长边摆动，连接片也伸展开。随着水越多，第二基体摆动的幅度越大，直到连接片绷直，连接片在绷紧状态下，第一基体和第二基体之间的角度小于90度。通过第二基体来挡住水，连接片绷直后，第一基体、第二基体和连接片之间形成稳定的三角结构，保证对水的阻挡。
