The drainage device of the dredged sand transport ship comprises a cavity and a water suction pump, the cavity communicates with the water inlet end of the water suction pump, a drainage pipe is installed at the water inlet end of the water suction pump through a flange, and a cover plate structure is fixedly installed in the cavity; the cover plate structure comprises a water permeable plate, a permeation plate and a permeation bin, the water permeable plate is fixedly installed on the inner wall of the cavity, the permeation plate is installed on the water permeable plate through bolts, the permeation bin is formed in the upper portion of the water permeable plate, and permeation holes are formed in the permeation bin; a drainage hole is formed in the side wall of the drainage pipe, and the drainage hole is communicated with the permeation hole and the drainage pipe; a buffer part is arranged between the drainage pipe and the cavity and is positioned below the permeable plate; the bottom of the water suction pump is fixedly connected with a damping mechanism used for damping when the water suction pump pumps water. Dredged sand can be effectively prevented from entering the drainage pipe, and the situations that the drainage pipe is blocked and a water suction pump is caused are avoided.
本发明公开了一种疏浚砂运输船排水装置,包括腔体和抽水泵,腔体与抽水泵进水端连通,抽水泵的进水端通过法兰安装有排水管,腔体内固定安装有盖板结构;盖板结构包括透水板、渗透板和渗透仓,透水板固定安装在腔体的内壁上,渗透板通过螺栓安装在透水板上,渗透仓开设在透水板的上部,渗透仓内开设有渗透孔;排水管的侧壁上开设有排水孔,排水孔与渗透孔连通,且排水孔与排水管连通;排水管与腔体之间设置有缓冲件,缓冲件位于透水板的下方;抽水泵的底部固定连接有用于对抽水泵抽水时减震的减震机构。该发明可以有效防止疏浚砂进入到排水管内,避免堵塞排水管以及造成抽水泵的情况发生。
