Description
Technical field
The present invention relates to one can the collapsible moon pool retaining device of opening and closing, belong to Naval Architecture and Ocean Engineering technical field。
Background technology
Along with mankind's increase in demand to the petroleum gas energy, the exploitation of land resources can not meet existing oil supply, offshore oil exploration and exploitation are very urgent, various novel marine settings continues to bring out under the new situation at this, drill ship and all kinds of drilling platforms as the main product of offshore drilling equipment also in constantly development and innovation。On drill ship and all kinds of drilling platforms, all can be provided with this structure of moon pool。Moon pool is normally in the middle part of platform, from the straight-through bottom of upper deck。Various drilling equipments and pipeline pass through to carry out exploitation work from moon pool。Owing to moon pool directly contacts with sea water, contact with sea water can produce climbing of whirlpool and wave after moon pool pool wall。Wind, ripple, stream combined effect under, sea water also can form vertical " piston " motion and move with " the rocking " of horizontal direction。Ocean operation and life on ordinary days are brought tremendous influence。
In order to tackle these adverse effects of moon pool, it is typically in moon pool structure adding additament and add in moon pool can the sideboard of open and close type, due to moon pool limited space, adding additament and will certainly reduce the effective operation space of moon pool, the layout of drilling equipment also can be had a certain impact by accrete existence。
For moon pool structure, when works navigates by water, first incoming flow meets with the forward position of moon pool, forms whirlpool, whirlpool constantly expands along water (flow) direction, reaching moon pool tailing edge place, and pool wall collision, cause climbing of wave, liquid level in moon pool is due to the effect of disturbance, also can produce violent oscillation action, therefore, design a kind of wave that can effectively reduce and climb and the device of wave oscillations is highly important。
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provide one can the collapsible moon pool retaining device of opening and closing, actively baffle plate can be opened and closed by driving device, thus avoiding the wave impact on moon pool。
Technical scheme: for achieving the above object, the present invention's can the collapsible moon pool retaining device of opening and closing, including actively baffle plate, driven baffle plate and driving device, described active baffle plate one end is hinged on crank, the other end is hinged with driven baffle plate one end, and described active baffle plate is hinged with driving device near one end of crank, and driving device and crank are fixed on works, works is provided with guide rail, driven baffle plate is provided with the guide wheel along guide rail movement；When driving device drives that actively baffle plate rotates around crank, the guide wheel of driven baffle plate is along guide rail movement。
As preferably, described driving device comprises oil cylinder and piston, and oil cylinder is fixed on works, piston one end and actively panel hinge, when piston is flexible, drives active baffle plate around crank rotation。
As preferably, described piston is by the first fixing axle and actively panel hinge, and oil cylinder is connected with works by the first rotating shaft。
As preferably, described crank comprises spectacle eye, the second rotating shaft and the second fixing axle, described spectacle eye one end is hinged on lower installation board by the second rotating shaft, the spectacle eye other end is connected by the second fixing axle is fixing with upper mounting plate, upper mounting plate is fixing with actively baffle plate to be connected, lower installation board is fixing with works to be connected, and spectacle eye relatively common hinge rotates more flexible, also can effectively prevent the concentration of stress simultaneously。
Beneficial effect: the present invention's can the collapsible moon pool retaining device of opening and closing, structure is ingenious, it is possible to effectively suppresses climbing of wave in moon pool, reduces the wave impact on moon pool internal structure, alleviate sea water platform is impacted, it is ensured that platform is the device of normal table work under various operating modes。

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described。
As shown in Figures 1 to 6, the present invention's can the collapsible moon pool retaining device of opening and closing, including actively baffle plate 1, driven baffle plate 2 and driving device, described active baffle plate 1 one end is hinged on crank 3, the other end is hinged by hinge 5 and driven baffle plate 2 one end, and described active baffle plate 1 is hinged with driving device near one end of crank 3, and driving device and crank 3 are fixed on works, works is provided with guide rail 7, driven baffle plate 2 is provided with the guide wheel 6 moved along guide rail 7；When driving device drives active baffle plate 1 to rotate around crank 3, the guide wheel 6 of driven baffle plate 2 moves along guide rail 7。
In the present invention, described driving device comprises oil cylinder 4 and piston, and oil cylinder 4 is fixed on works, and piston 41 one end is with actively baffle plate 1 is hinged, when piston 41 stretches, drives actively baffle plate 1 to rotate around crank 3。Described piston 41 is connected with actively baffle plate 1 is fixing by the first fixing axle 42, and oil cylinder 4 is connected with works by the first rotating shaft 43。
In the present invention, described crank 3 comprises spectacle eye the 31, second rotating shaft 32 and the second fixing axle 33, described spectacle eye 31 one end is hinged on lower installation board 35 by the second rotating shaft 32, spectacle eye 31 other end is connected by the second fixing axle 33 is fixing with upper mounting plate 34, upper mounting plate 34 is connected with actively baffle plate 1 is fixing, and lower installation board 35 is fixing with works to be connected。First rotating shaft 43 and the second rotating shaft 32 diameter take 15～20cm, and the first fixing axle 42 and the second fixing axle 33 diameter take 12～15cm, and the first fixing axle 42 and the second fixing axle 33 are provided with sealing device and axle sleeve。
In the present invention, actively baffle plate 1 and driven baffle plate 2, long limit is of a size of b, and short side dimension is c, long limit and minor face b:c=1～1.5。, when moon pool length is less than 15 meters, actively the thickness of baffle plate 1 and driven baffle plate 2 takes 8mm, and when length is more than 15 meters, actively the thickness of baffle plate 1 and driven baffle plate 2 takes 10mm, and material takes Q235 steel, for ensureing works intensity, can add vertical bone。
When drill ship is in drillng operation state, driving device drives actively baffle plate drive to be close to moon pool inwall from when baffle plate, in vertical state, does not affect normal drilling well mining operations；When boats and ships stop operation or are in operational configuration, driving device drives actively baffle plate and driven baffle plate to be the level of state, and now actively baffle plate can overcome the disadvantages that the deficiency of the big hatch frame sudden change of moon pool, effectively weakens whirlpool in moon pool, thus playing the effect of drag reduction。
The above is only the preferred embodiment of the present invention; it is noted that, for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
