Seepage-proofing and water-stopping structure for water conservancy project

ZHANG HONG / LIU XUEFENG / XI JIANQIANG

The seepage-proofing and water-stopping structure for the water conservancy project comprises an adjusting mechanism, the adjusting mechanism comprises two vertical plates, the lower sides of the opposite side walls of the two vertical plates are fixedly connected with transverse plates, the upper ends of the two transverse plates are fixedly connected with adjusting blocks, the same adjusting plate is arranged above the two adjusting blocks, and the adjusting blocks are fixedly connected with the adjusting plates. An open groove is formed in the lower end of the adjusting plate, two bidirectional threaded rods are rotationally connected in the open groove, the two bidirectional threaded rods both penetrate through the two adjusting blocks in a threaded mode, the two bidirectional threaded rods are in transmission connection through a first transmission mechanism, and a rotating rod is arranged in the open groove; the rotating rod and the bidirectional threaded rod are in transmission connection through a bevel gear set, and the upper end of the rotating rod rotationally penetrates through the adjusting plate and is coaxially and fixedly connected with a first rotating handle. The device can be used for mounting and protecting channels with different shoulder widths, is wide in application range and can be reused.

本发明公开了一种水利工程用防渗止水结构，包括调节机构，调节机构包括两块竖板，两块所述竖板相对侧壁下侧均固定连接有横板，两块所述横板的上端均固定连接有调节块，两块所述调节块的上方设有同一块调节板，所述调节板的下端设有开槽，所述开槽内转动连接有两根双向螺纹杆，两根所述双向螺纹杆均螺纹贯穿两块调节块设置，两根所述双向螺纹杆之间通过第一传动机构传动连接，所述开槽内设有转动杆，所述转动杆与双向螺纹杆之间通过锥齿轮组传动连接，所述转动杆的上端转动贯穿调节板并同轴固定连接有第一转柄。本发明可以对不同肩宽度的渠道进行安装和防护，适用的范围较广且可以二次利用。
