Description
Technical field
The present invention relates to topside suction inlet and a kind of dredge boat of dredge boat.
Background technology
At present, the design scheme (seeing Fig. 1) of the topside suction inlet pipe of general dredge boat is by the topside suction inlet pipe 3 of dredge boat, directly is welded on the hull bulwark of dredge boat; The dredge pump suction inlet tube connector 1 in left side is to be connected with topside suction inlet pipe 3 by slide valve 2 use flanges; The outboard rake on right side is inhaled the pipe 4 of dredging, with the rake pipe crane on ship, to slide into the joint of topside suction inlet pipe 3 above the other slideway of bulwark, the outboard rake is inhaled the fixing of the pipe 4 of dredging, to rely on gradient downward between slideway and bulwark and outboard rake to inhale the dredge weight of pipe 4 and downward rake suction, the outboard rake is inhaled to the pipe 4 of dredging and tightly be fixed between topside suction inlet pipe 3 and slideway, in figure, 100 is hull bottom.
Dredge boat is when harrowing the suction dredging operation: in due to seabed silt, contain a large amount of hard grains of sand and rock etc., by mud inlet 410, entered, by outboard, harrow inhale dredge pipe 4, topside suction inlet pipe 3 and dredge pump suction inlet tube connector 1 after in the process that dredge pump mud suction mouth 110 is discharged, to heavy wear can be cause to its all inner-walls of duct, even breaking of pipeline can be caused.But, when outboard rake is inhaled the pipe 4 of dredging and caused wearing and tearing production pipeline breaking, this pipeline can be hung on the dredge boat main deck and repairs.When dredge pump suction inlet tube connector 1 causes wearing and tearing production pipeline breaking, can close immediately slide valve 2, then pull down this pipeline and aboard ship repair.And when topside suction inlet pipe 3 caused wearing and tearing production pipeline breaking, external dynamic sea will directly enter in cabin and cause the accident.Therefore require regularly topside suction inlet pipe 3 to be carried out to special survey, and especially topside suction inlet pipe 3 is thickeied when shipbuilding, to increase its antiwear property.
Therefore, when dredge boat is being harrowed while inhaling dredging operation, topside suction inlet pipe 3 is once serious wear occurs, should stop dredging operation, and the outboard rake is inhaled to the pipe 4 of dredging and sling, carry out shutoff (seeing accompanying drawing 2) sealing plate 5 being inserted into to topside suction inlet pipe 3 places, then return shipyard topside suction inlet pipe 3 is repaired specially.Will have influence on the dredging operation engineering like this, increase maintenance cost, reduce dredge boat work production efficiency.
