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

Detailed description of the invention
Below contrast accompanying drawing and combine preferred embodiment the invention will be further described.
As shown in Figure 3, a kind of dredge boat, comprises the suction of dredge pump suction inlet tube connector 1, topside suction inlet pipe 3 and outboard rake and to dredge pipe 4, also comprise topside suction inlet pipe neck bush 7, gas tube 10 and air pressure testing agency 9; Dredge pump suction inlet tube connector 1, topside suction inlet pipe 3 and outboard rake suction pipe 4 of dredging are connected successively, wherein, are provided with slide valve 2 between dredge pump suction inlet tube connector 1 and topside suction inlet pipe 3; The outboard rake suction on right side is dredged pipe 4, it is the joint sliding into topside suction inlet pipe 3 with the rake pipe crane on ship above the slideway 102 on bulwark 101 side, the fixing of pipe 4 of dredging inhaled by outboard rake, be rely on gradient downward between slideway and bulwark and outboard to harrow the weight and downward rake suction of inhaling pipe 4 of dredging, outboard harrowed suction pipe 4 of dredging and be tightly fixed between topside suction inlet pipe 3 and slideway.
Topside suction inlet pipe neck bush 7 is arranged in topside suction inlet pipe 3, forms enclosure space between the outer wall of topside suction inlet pipe neck bush 7 and topside suction inlet pipe 3 inwall.In a preferred embodiment, the both sides outer wall of topside suction inlet pipe neck bush 7 is respectively equipped with annular boss 701, the middle concave of annular boss 701 circularizes groove, sealing ring 6 is provided with between annular boss 701 and topside suction inlet pipe 3 inwall, sealing circle 6 is set in annular groove, thus form aforementioned enclosure space based on this boss 701 and sealing ring 6, avoid air leakage.Described annular boss 701 realizes by pricking a circle steel plate on neck bush, also can be integrative-structure with neck bush main part.Sealing ring 6 can select the existing encapsulant such as rubber ring, elastoplast to be prepared from.
The first end of described gas tube 10 is communicated with described enclosure space, and the second end is used for being connected with inflation mechanism, and wherein the second end is provided with charge valve 8 for completing inflation rear enclosed gas tube.
Described air pressure testing agency 9 is for detecting the air pressure in described enclosure space by described gas tube.Air pressure testing agency 9 directly can adopt pressure meter, can judge the atmospheric pressure value of enclosure space by reading manometric force value.
When using dredge boat of the present invention, utilize inflation mechanism, the space closed to this by charge valve 8 and gas tube 10 is filled with the compressed air of about 1kg and closes charge valve 8 or carry out pressurize.When dredge boat is when carrying out dredging operation, the pressure of pressure meter 9 once be shown as zero or lower than predetermined pressure, then shows that the damaged needs of anti-wearing liner 7 are changed.At this moment need to stop dredge pump work immediately, as shown in Figure 4, first outboard being harrowed suction pipe 4 of dredging hangs on main deck, again sealing plate 5 is hung in topside suction inlet pipe 3 place and carry out shutoff, and then dredge pump suction inlet tube connector 1 and slide valve 2 are pulled down successively, then damaged anti-wearing liner 7 is extracted out, the anti-wearing liner 7 more renewed, after being connected by other pipeline successively, dredge boat just can dredging operation immediately.
