Description
Technical field
The present invention relates to a kind of ice resistant device, be suitable for the protection of marine site, ice formation ocean engineering structure spud leg.
Background technology
The ice resistant device of existing ice formation ocean engineering structure is the bullet that is installed on the spud leg, just has to put, be inverted or just be inverted combination.Some is fixed on the spud leg, and some can lean on floating drum along with tidal undulation.Rely on the effect of cone angle to make ice raft change bending failure into by squeeze and destroy, reach open ice, the effect of trash ice.Yet existing ice resistant device all is a shell structure, and additional bevels makes the contact area of ice raft and structure increase, and positive back taper form also may cause card ice phenomenon.In a word, existing ice resistant device all belongs to passive protection, does not play absolute good anti-ice cushioning effect.For settling the matter once and for all, the needs design is a kind of can to adapt to tidal range, can initiatively resist ice again, and the good effective ice resistant device of damping effect.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of self-lifting active ice-resistant damping device, this ice resistant device not only can be complied with tidal range, autonomous lifting, and can eliminate the effect of icing excited vibration, protect marine site, ice formation ocean engineering structure effectively.
For achieving the above object, the present invention takes following technical scheme:
A kind of self-lifting active ice-resistant damping device comprises, neutralizes and descends shellring shape wing plate and be erected at passive liner plate between each layer wing plate, offers porose on the middle wing plate; Be distributed with anti-ice cable between three layers of wing plate, described anti-ice cable passes middle wing plate, and is fixed in upper and lower wing plate; Upper flange links to each other with lifting gear; Below lower wing plate, be fixed with floating drum.
Self-lifting active ice-resistant damping device of the present invention, in three layers of wing plate, it is maximum that the wing centre section board diameter is preferably.Be weight reduction, middle wing plate can be made of inner ring plate and outer ring plate, connects by junction plate between the described inside and outside ring flat-plate.
For further improving anti-ice effect, anti-ice filler preferably is set between three layers of wing plate in anti-ice cable, described anti-ice filler has elasticity and corrosion-resistant.Described anti-ice filler can be rubber.
The electric winch that the lifting gear that the present invention adopts, its formation can comprise the cable that is fixed on the upper flange, be connected with cable by pulley.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention adopts the method that elastic materials such as anti-ice cable wire and rubber combine, both saved the steel material consumption of ice resistant device, and can effectively eliminate the adverse effect of ice excited vibration to ocean engineering structure, reach good protective action.2, adopt the people of ice resistant device to be lifting among the present invention, can reach the effect that initiatively opens ice.3, the wing plate among the present invention, liner plate and anti-ice cable can assemble in split, have both simplified the build process of ocean engineering structure, also provide method and thinking for the anti-immediately ice of marine structure.4, adopt floating drum among the present invention, regulated the floating position of ice resistant device, can adapt to the variation of tidal range.5, each parts are conventional products among the present invention, and convenient production reduces cost.

The specific embodiment
Below in conjunction with drawings and Examples, the inventive method and device are described in detail.
The present invention mainly comprises several sections: ice-resistant damping device, lifting gear, self-buoyant unit.
Ice-resistant damping device comprises upper flange 3, middle wing plate 4, lower wing plate 5 and liner plate 11, shuttle back and forth in addition between three layers of wing plate anti-ice cable 6 and be full of the elasticity corrosion resistant substance such as rubber in gap.Anti-ice cable 6 is fixed on upper flange 3 and the lower wing plate 5 by the tight device of rope, the aperture during the centre is passed on the wing plate 4.When ice sheet extruding ice resistant device, a part is split disconnected by cable wire or is suffered bending failure along inclined-plane climbing (or decline), thereby reaches the purpose that opens ice.Also have the part ice sheet to be expressed on the rubber material, because elasticity is so slow down or eliminated the effect of ice excited vibration.This ice-resistant damping device is a kind of form of passive anti-ice, can deal with for less ice condition.
Lifting gear comprises lifting cable 8, pulley 9 and electric winch 10.Pulley 9 is distributed in the relevant position of Platform Deck 2, and the electric winch setting above deck.When the serious ice condition of pre-generation, the staff can open electric winch, and ahead and astern makes ice-resistant damping device move up and down along spud leg 1 repeatedly, thereby makes near the seawater the leg post to freeze.This has just reached the initiatively purpose of anti-ice, and effect is more effective than the anti-ice of simple structure itself.
Self-buoyant unit is exactly undersea floating drum 7, and when lifting gear did not start, lifting cable 8 was in relaxed state, and the ice-resistant damping device of this moment leans on the buoyancy of floating drum 7 and floats on the water surface, complies with the variation of tidal range.
In order to satisfy the technology of partial installation, ice-resistant damping device can be processed into the part of two symmetries, every part is semi-ring, three liner plates, 11 upper, middle and lower wing plates are respectively arranged, in 0 degree, 90 degree and the 180 degree position welding of ring, utilize screw bolt and nut to be assembled together by the pilot hole on the liner plate 11 12 then respectively.Do like this and make ice-resistant damping device after ocean engineering structure installs, can assemble up very easily.
