Device for reducing silt diffusion during construction of dredger
The device is arranged on a large sand pumping arm above a cutter suction head, the large sand pumping arm is made of a hollow steel pipe, the cutter suction head is arranged at the lower end of the large sand pumping arm, a sand pumping pipe is arranged in the large sand pumping arm, and the lower end of the sand pumping pipe is connected with the top of the cutter suction head. Comprising a flexible flange which is sleeved and fixed on a sand pumping big arm, the bottom of the flexible flange is provided with an anti-diffusion cover with a bottom opening for covering a cutter suction head, and the anti-diffusion cover is provided with a jet flow sand breaking device which sprays towards the lower end opening of the anti-diffusion cover. The device is simple and clear in structure, adopted equipment is easy to manufacture, construction is convenient to operate, diffusion of silt can be effectively prevented when a desilting ship is used for desilting, secondary pollution to clean water during desilting is reduced, reservoir water quality is protected, environment-friendly desilting is achieved, desilting and desilting efficiency is effectively improved, and the device is suitable for popularization and application. And the desilting cost is reduced.
本发明公开了一种减少清淤船施工时泥沙扩散的装置，设置在绞吸头上方的抽沙大臂上，抽沙大臂采用中空钢管制成，绞吸头设在抽沙大臂下端，抽沙大臂内部设置抽沙管，抽沙管下端与绞吸头顶部连接，包括套装并固定在抽沙大臂上的柔性法兰，柔性法兰底部设有底部敞口将绞吸头罩住的防扩散罩，防扩散罩上设有朝向防扩散罩下端敞口喷射的射流碎砂装置。本发明结构简明，所采用的设备易于制作，施工起来方便操作，可以有效的防止清淤船在清淤时防止淤泥的扩散，减少了清淤时对清洁水体的二次污染，保护了水库水体质量，实现了环保清淤，同时有效提高了清淤排沙作业效率，降低了清淤成本。
