The purpose of this utility model provides a kind of underwater silt remover, and its good stability is difficult for tilting; It rises and falls controlled good, both has been easy to emerge, and can provide preferable specific pressure to soil layer again; And the foreign material at its suction inlet place are very easily removed.

The purpose of this utility model is achieved through the following technical solutions, a kind of underwater silt remover, comprise a fuselage, with the relatively-stationary driver part of fuselage, be installed in rotation on both sides, fuselage below and respectively with described driver part in two running gears that motor links to each other, one with fuselage relative fixed and the dredge pump that links to each other with dredge pump motor in the described driver part, be fixed on the buoyant device on the fuselage symmetrically, and the mud pipe that is communicated with the dredge pump outlet.Wherein, dredge pump and dredge pump motor are horizontal and are installed on the fuselage basal surface, establish a storage glove compartment that is communicated with it before the dredge pump suction inlet; This storage glove compartment lower end is uncovered, and a dismountable cover plate is installed in the upper end; And the dredge pump suction inlet place in this storage glove compartment establishes a filter screen.

In above-mentioned underwater silt remover, described buoyant device can be a pair of fuselage front and back or the both sides buoyant device place, variable volume that is installed in symmetrically.The buoyant device of described variable volume can be an air bag, also can be to be that rigid material, top or side are the container that flexible material is made by the bottom.

The utility model has the advantages that because dredge pump and dredge pump motor are to be horizontal to be installed on the fuselage basal surface, machine gravity is reduced greatly, stability improves greatly, like this, after machine is subjected to the external force run-off the straight, can automatically reset in case external force is removed.Because at dredge pump suction inlet front installing storage glove compartment, mud can suck from storage glove compartment lower ending opening, enter dredge pump by the dredge pump suction inlet again, the filter screen at dredge pump suction inlet place can (be store glove compartment but be positioned at) outside with the foreign material retaining, open the cover plate at storage glove compartment top, can take out these foreign material easily.Again owing to be provided with the buoyant device of variable volume, change aeration quantity and change the buoyancy size thereby can utilize, like this, when running into fault, machine can make its emerge back towing disembarkation and place under repair easily; In addition, can how much change the specific pressure of machine, thereby can make machine adapt to the soil layer condition of underwater complex according to venting to mud.

Below in conjunction with accompanying drawing an embodiment of the present utility model is done detailed explanation, so that more clearly understand feature and advantage of the present utility model.
