Description of drawings
Fig. 1 is the structural representation of multifunctional small waterplane area ship of the present invention.
The specific embodiment
Multifunctional small waterplane area ship is mainly by platform 6, submerged body 8 with captive joint their column 7 and form all welded construction.Platform 6 is made of watertight structure, and four work piles 5, gadder 4, head and the tail anchor 2, side anchor 3, operator's compartment, daily life storehouse etc. are arranged on the platform; There is the well that encloses that operation is used under the water supply middle part above deck; The watertight compartment that a plurality of separations are arranged in the buoyancy aid 8 is joined powerful ballasting system, establishes ballast tank; Adding upper mounting plate has very big buoyancy reserve, no matter platform, column or buoyancy aid are subjected to symmetry or imparity is destroyed, all can have very strong existence to ensure power; On submerged body afterbody both sides a spiral pushing device 1 is arranged respectively, the submerged body stem respectively has a spiral lateral thruster 9; Be distributed with four sinker weights 10 at the bottom of the submerged body.
Two Bower Anchors before and after this multifunctional small waterplane area ship has, about four side anchors, Bower Anchor is by winch 2 folding and unfoldings, side anchor is by winch 3 folding and unfoldings, numerous ship anchor, it is steadily fixing that ship is able to.
4 tens of tons of cast steel weight 10 hangings are in the submerged body bottom, by the winch folding and unfolding of weight.Behind the heavy seat of the weight sea bed, half submerged body buoyancy of diving and weight tension force increase, and reach accurate location, and restrict the unsteady lifting that this ship is subjected to wave effect to greatest extent, reach the smooth conditions of operation.
Ballast tank water filling in submerged body, submerged body can sink, and center of gravity reduces, and stability increases.Six anchors are grabbed the end and are discharged weight simultaneously and can satisfy the inaccessible super dark location of work pile, and weight sinks to the bottom also can keep the platform sink-float that a part of buoyancy causes because of load change when overcoming operation.With this way, the tons per centimeter immersion that overcomes little line water surface partially surfaced condition little (susceptibility to drinking water is big), need strict control changes in weight to prevent the problem that rises and falls significantly.
This multifunctional small waterplane area ship, there are 4 work piles to insert the seabed fixed platform, six Bower Anchors in front and back, side anchors are coordinated the location, the weight sinker is pricked the end and is prevented platform sink-float and mobile, submerged body sinks to reducing the stormy waves interference in addition, integrate multiple location way, can under different condition, select one or more locate modes for use, significantly reduced the construction restriction.
Advance or when mobile, because of screw propeller dive dark big, water surface exciting force is little, water depth pressure is big, can improve propulsion coefficient and anti-cavity ability, and can save energy consumption greatly; Its power not only has two main spiral propellers 1, also has two side spiral propellers 9, has improved the speed of a ship or plane of ship, alerting ability and the speed that Chuan Bo Hui changes and locatees greatly.
