The invention relates to the technical field of excavation, and discloses a device for preventing an underwater-operation water suction pump from sinking into sludge. The device comprises a water pump; a traction rope is fixedly connected to the upper end of the water pump; a bidirectional ratchet gear is movably connected to the end, far away from the water pump, of the traction rope; a floatingblock is fixedly installed at the upper end of the bidirectional ratchet gear; high and low U-shaped pipes are fixedly installed in the floating block; a connection relation is generated between the floating block and the water pump through buoyancy of the floating block; the bidirectional ratchet gear is fixedly installed at the lower end of the floating block; the water pump is kept not to sinkdownwards by winding the traction rope; and thus the underwater-operation water suction pump is prevented from sinking into sludge. the high and low U-shaped pipes with different pipe heights are fixedly installed in the floating block, the height of the horizontal plane in a water pit is affected until a horizontal height difference occurs in the pipes, and therefore a rotary switch of the bidirectional ratchet gear is triggered, thus normal work of the water pump is guaranteed, sludge is prevented from affecting the work progress, and the service life of the water pump is prolonged as well.

    本发明涉及挖方技术领域,且公开了一种防止水中作业抽水泵陷入淤泥的装置,包括抽水机,抽水机的上端固定连接有牵引绳,牵引绳远离抽水机的一端活动连接有双向棘齿轮双向棘齿轮的上端固定安装有浮块,浮块的内部固定安装有高低U形管,通过浮块自身浮力于抽水机产生连接关系,浮块下端固定安装有双向棘齿轮,通过对牵引绳的收卷,保持抽水机不向下深陷,实现了防止水中作业的抽水泵向淤泥深陷。通过浮块内固定安装管高不等的高低U形管,通过将水坑内的水平面高度影响至管内出现水平高度差,从而触发双向棘齿轮的转动开关,进而保证了抽水机的正常工作,防止了淤泥影响了工作进度,也延长了抽水机的使用寿命。
