Embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
One embodiment of the present of invention provides a kind of floating body guide pile, reference picture 1, including connecting pole 110 and connected respectively
It is connected to the buoyancy compartment 120 and ballast tank 130 at the both ends of connecting pole 110.Buoyancy compartment 120 has and disconnected first cavity of seawater
121；Ballast tank 130 defines a cavity 131, when floating body guide pile works in the seawater, the cavity 131 of ballast tank 130
Connected with seawater；Also include truss 160, be fixedly connected between buoyancy compartment 120 and connecting pole 110, or be fixedly connected on ballast
Between cabin 130 and connecting pole 110, or connecting pole 110 is separated into two sections vertically and is fixedly connected on two sections of connecting poles 110
Between, truss 160 can allow ocean current to pass through.Here " floating body ", refers to suspending in water to sink, but will not also float
The object of shifting；" floating body " is different from " bleaching body ", and " bleaching body " refers to floating on the water surface, and the thing of drift can be acted on external force
Body.
Buoyancy compartment 120 does not connect with seawater, refers to that the first cavity 121 of buoyancy compartment does not connect with seawater, it can
To be closing, can also be connected with ambient atmosphere.
There is top a and bottom b, top a to be located at buoyancy compartment 120 away from connecting pole 110 for reference picture 1, floating body guide pile 100
One end, bottom b is located at the other end of the floating body guide pile relative to top a；(i.e. buoyancy compartment is complete for the displacement of buoyancy compartment 120
When being immersed in seawater, the quality of the water arranged) it is not less than the gross mass of floating body guide pile, the gross mass of floating body guide pile is not small
In 50 tons.The displacement of buoyancy compartment 120 is the quality that buoyancy compartment 120 is completely immersed in the water arranged in seawater, quality here
(1 ton=1000 kilograms) are represented with tonnage with displacement, therefore, when floating body guide pile is located in seawater, suffered is floating
Power can offset gravity, therefore floating body guide pile can suspend in the seawater.When the floating body guide pile works in the seawater,
Inclination angle caused by external physical force effect is lower is not more than 1 degree, is requiring the strict application scenario of stability requirement, can also lead to
Cross change pile parameter so that the floating body guide pile is not more than 0.1 degree in caused inclination angle under external physical force effect.
The displacement of buoyancy compartment 120 is not less than the gross mass of floating body guide pile, and quality and displacement here use tonnage
To represent.Therefore, when floating body guide pile is located in seawater, suffered buoyancy can offset gravity, therefore floating body guide pile energy
It is enough to suspend in the seawater.In certain embodiments, the total displacement of buoyancy compartment 120 is greater than 200t (1t=1000Kg).One
In a little embodiments, in the case of no ballast, the quality of buoyancy compartment 120 accounts for the gross mass of floating body guide pile no more than 1/3.It is floating
The shape in power cabin 120 can be cube shaped, cuboid.When floating body guide pile works in the seawater, with centre of buoyancy M and again
Heart G, center of gravity G is between centre of buoyancy M and bottom b.The centre of buoyancy M of buoyancy compartment 120 will the center of gravity away from pile body, and its draining as far as possible
Amount is big, the two comprehensive conditions, and the structure of buoyancy compartment 120 is preferably rectangular parallelepiped structure of the section for square, and cuboid
Height be more than section width, i.e. the height of buoyancy compartment 120 should be suitably larger.
Further, full light weight (density is less than water) can be filled in the first cavity 121 of buoyancy compartment 120 and is not absorbed water
Material, can so avoid buoyancy compartment 120 when being corroded or external force is destroyed, avoid seawater or other materials from entering the
One cavity 121, ensure the function of buoyancy compartment 120.Light weight and material its quality for not absorbing water is for floating body guide pile
It can be ignored, as one embodiment, light weight and the material not absorbed water, for example can be polyvinyl chloride, foam etc.
Organic material.
Reference picture 3, it is contemplated that the influence of ocean current, truss 160 is provided between buoyancy compartment and connecting pole, when floating body positions
When stake works in the seawater, energy by ocean current passes through out of truss 160.Truss 160 be located at floating body guide pile along prolonging direction with sea
Position corresponding to stream, the length of truss 160 are not less than the depth or substantially suitable with ocean current depth of ocean current, that is to say, that truss
160 length is typically determined by the ocean current depth for specifying marine site and preferably not less than specifies the ocean current depth in marine site, but is considered
To actual ocean current depth and cost control, of length no more than 50 meters of truss 160, the length of truss 160 refers in stake
Its height when body works in the seawater.
When sea is acted on by wind-force, surface seawater athletic meeting forms stormy waves, even if in the case of wind-force maximum, its energy
The surface seawater depth enough influenceed is typically not more than 10 meters, therefore the center of gravity G of floating body guide pile will be less than stormy waves depth.Center of gravity
G should be more than 10 meters apart from sea level S distance, and the distance between center of gravity G and centre of buoyancy M should be more than 8 meters.In addition, in order to keep away
Exempt from ocean current influence, center of gravity G should also avoid the position of truss 160.In certain embodiments, it is assumed that truss 160 is 50 meters, and purlin
Frame 160 between buoyancy compartment 120 and connecting pole 110, then the center of gravity of the floating body guide pile will apart from sea level S up to 60 meters with
On, up to more than 100 meters, the centre of buoyancy M of floating body guide pile is located in buoyancy compartment 120 and between centre of buoyancy M and center of gravity G pile body total length
Distance be not less than 58 meters, then center of gravity G and sea level S distance are bigger than the length of truss 160 more than 10 meters, centre of buoyancy M and center of gravity G
The distance between it is bigger than the length of truss 160 more than 8 meters.
Reference picture 1 simultaneously combines Fig. 2, and truss 160 can be made up of more vertical first purlin posts 161, more first purlin posts 161
Between there is space, one end of more first purlin posts 161 is connected with the buoyancy compartment 120, and the other end connects with the connecting pole 110
Connect.Connected between adjacent first purlin post 161 by one or more second purlin posts 162.More first purlin posts 161, the second purlins
The lateral dimension of every in post 162 is much smaller than connecting pole, i.e., thin more than connecting pole 110, when floating body guide pile in the seawater
During work, energy by ocean current passes through from the space between more first purlin posts 161, the second purlin post 162.The transverse direction of overall truss 160
Size, i.e., perpendicular to connecting pole 110 prolonging direction size, can be identical with the lateral dimension of connecting pole 110.Due to truss
160 every first purlin post 161, the second purlin post 162 are thinner, in order to ensure will not to break under ocean current or stormy waves impact, often
The first purlin of root post 161, the intensity of the second purlin post 162 are sufficiently high.
Further, through hole (not marking) is also provided with the side wall of ballast tank 130, the quantity of through hole should not mistake
More, general one to two, the size of through hole is also unsuitable excessive, as long as seawater can be made smoothly to enter ballast tank 130 and caused
The cavity 131 that ballast tank 130 limits connects with extraneous seawater.In certain embodiments, through hole can also use seal
(not shown) is sealed, to isolate cavity 131 and the external world.So in transportation, ballast tank 130 can seal,
In order to transport.Ballast tank 130 can be unloaded, floating body guide pile can also be increased weight by loading weight, to float
The center of gravity G of body guide pile is further dragged down, to increase centre of buoyancy away from (i.e. the distance between center of gravity G and centre of buoyancy M), therefore connecting pole
110 length need not set very long, and floating body guide pile in the seawater also can stable position.The shape of ballast tank 130 can
With using any shape, for example, it is square, cylindrical etc..The quality of ballast tank 130 is as far as possible big, and volume is small.In some implementations
In example, when ballast tank 130 is unloaded, the quality sum of ballast tank 130 and connecting pole 110 is more than the 2/3 of whole pile quality；Ballast
The quality sum of the full load of cabin 130, ballast tank 130 and ballast accounts for the proportion of the quality of whole pile body more than 1/2.
When unloaded, the quality of connecting pole 110 accounts for the proportion of floating body guide pile gross mass more than 1/3.In certain embodiments,
Uniform quality of the connecting pole 110 along its prolonging direction, even intensity.Floating body guide pile is when seawater works, in vertical state, i.e.,
When without stormy waves or without ocean current, floating body guide pile and sea level S are substantially vertical.Floating body guide pile 100 must have enough matter
Amount could be stablized.Because the bottom of pile body in embodiments of the invention has ballast tank 130, by being filled into ballast tank 130
Ballast, therefore connecting pole 110 need not have the requirement that very big length may also meet quality, in certain embodiments, if
Floating body guide pile 100 is steel construction, i.e. buoyancy compartment 120 and connecting pole 110 is stainless steel, in order to realize stable position, such as
In the case of the width that connecting pole 110 can be arranged on is 3 meters, the length of connecting pole 110 is greater than 35 meters.
In certain embodiments, in order to fill ballast into ballast tank 130, passage 140 can also be set.In some realities
Apply in example, passage 140 is located in connecting pole 110 and extended along connecting pole 110, through connecting pole 110 and buoyancy compartment 120, passage
For loading ballast, when floating body guide pile works in the seawater, one end across the sea of passage connects with 140 ambient atmospheres
The logical, other end of passage 110 is connected by ballast tank 130 with seawater, and passage 140 does not connect with the gas of buoyancy compartment 120.Ballast can
To be the larger material of stone, iron block isodensity.
With reference to figure 4, in certain embodiments, floating body guide pile can also include deposit cabin 150, be fixedly connected on buoyancy compartment
Between 120 and truss 160.Deposit cabin 150 defines second cavity 151, when floating body guide pile works in the seawater, storage
Standby cabin 150 can connect with seawater or not connect.When laying in tote (such as seawater or other objects) in cabin 150
Wait, deposit cabin 150 can increase the quality of pile body as connecting pole is served as.When load increase, need to increase floating body guide pile
During the load capacity that can be born, the tote laid in cabin 150 can be discharged to the part use for serving as buoyancy compartment, so
The buoyancy of floating body guide pile can be increased, so as to increase the load capacity of floating body guide pile.Cabin so is laid in by setting, can be with
Flexibly controlled according to extraneous circumstance pile body floating and sinking, so as to controlling the load capacity of pile body.Lay in the loading in cabin 150

When such as preceding floating body guide pile has deposit cabin 150, the first resistance piece 111 and the second resistance can also be set
Power part 112, will not be described in detail herein.
As one embodiment, ocean positioning 100 can be integrally steel construction, i.e.,：Connecting pole 110, buoyancy compartment 120 with
And ballast tank 130, truss 160 are steel construction.
The operation principle of the floating body guide pile of the embodiment of the present invention is as follows, when floating body guide pile is (i.e. flat not by lateral external forces
Row is in the active force in sea level S direction, such as the power applied by wind or wave, and the motion of ocean current is very slow, and it is to floating
Body guide pile apply power can be ignored for wind-force) effect when, it is perpendicular to sea level S, in initial shape
State；When being acted on by lateral external forces, lateral external forces will produce heeling moment, according to Ship Statics, floating body guide pile itself
Gravity will produce righting moment；In addition, pile body is in underwater part also by the effect of hydraulic pressure (pressure of seawater), hydraulic pressure
Produce resistance torque.Righting moment and resistance torque can resist heeling moment, promote floating body guide pile to return back to original shape
State.
When only considering wind-force effect, it is assumed that floating body guide pile tilts 0.1 ° (angle), and it is by wind-force, gravity and hydraulic pressure
The active force of (only considering centre of buoyancy M to the hydraulic pressure of bottom b parts here) three aspects, with reference to Fig. 1, specific force analysis is as follows.
Wind-force is acted on into floating body guide pile exposed to more than sea level S part, and the center for defining wind-force effect is wind
Power center P；The Center of Pressure of seawater is hydraulic pressure center.
It is H that wind-force center P, which is defined, apart from centre of buoyancy M distance1, center of gravity G is H apart from centre of buoyancy M distance2, hydraulic pressure center is with floating
Heart M distance is H3, definition wind-force is FP, buoyancy FM, gravity FG, the pressure of seawater is FW。
Wind-force FPOne heeling moment T is applied to floating body guide pilep, TpAbout：
Tp=FP·BC·H1
Wherein B is wind area, and C is coefficient of streamline shape (C=0.5).
Gravity FGOne righting moment T is applied to floating body guide pileG, TGAbout：
TG=FG·H2·Sin0.1°
Hydraulic pressure FWOne resistance torque T is applied to floating body guide pileW, as a simplified example, the resistance torque T of waterWCan
To be calculated using equation below：
TW=FW·H3=ρ VTH3
Wherein ρ is density of sea water, and V is the volume that floating body guide pile tilts the water arranged at 0.1 °, H3For hydraulic pressure center extremely
Centre of buoyancy M distance, T be hydraulic pressure coefficient (when the floating body guide pile of 50 meters of depths is fully immersed in seawater, suffered average water pressure
Equivalent to 2.5 atmospheric pressure, i.e. hydraulic pressure coefficient are 2.5.Here T=2 is taken).
When only considering gravity, when floating body guide pile can keep not tilting, righting moment T need to be metGNot less than tilting force
Square Tp, and in critical condition, righting moment TG=heeling moment Tp, i.e.,：
FG·H2Sin0.1 °=FP·BC·H1(formula one)
When only considering hydraulic pressure, when floating body guide pile can keep not tilting, resistance torque T need to be metWNot less than tilting force
Square Tp, and in critical condition, resistance torque TW=heeling moment Tp, i.e.,：
ρ·V·T·H3=FP·BC·H1(formula two)
By calculating, there is no the situation of truss compared with the situation for having truss in pile body, the weight of pile body is smaller, eats
Water depth is lower, and the area of exposure across the sea is then larger, and the distance between pile body center of gravity and centre of buoyancy also want small by one
A bit.If that is, according to formula one, there is no the situation of truss compared with the situation for having truss in pile body, heeling moment will
It is larger, and righting moment then can be smaller, that is to say, that when having truss, the stability of pile body is than no truss
When it is more preferable.
In the case that lower surface analysis floating body guide pile does not have truss, its stressing conditions：
Assuming that the parameters of floating body guide pile are as follows：Top a to bottom b distance is 51m；Total matter of floating body guide pile
Amount is about 60t；The cross section of connecting pole, ballast tank and buoyancy compartment is square, and connecting pole is arranged to the wide 3m in cross section, height
38m cylinder, buoyancy compartment 120 are arranged to the wide 5m in cross section, high 11m cylinder, and ballast tank 130 is arranged to the wide 4m in cross section, high
2m cylinder；Buoyancy compartment, connecting pole, ballast tank are made of the steel of same size.
When ballast tank 130 is unloaded, reference picture 2, floating body guide pile draft is about 43m, and buoyancy compartment 120 is exposed to sea
Plane S level above is about 8m, is calculated：
Wind area B=40m2；
Center of gravity G is about 32.5m apart from bottom b height；Then centre of buoyancy M is 41.5m apart from bottom b height, hydraulic pressure center
Height apart from bottom b is about 14.3m.
Then H1=5.5m, H2=8.5m, H3=27.2m；
Parameters are substituted into formula one, then obtain FP≈0.01t/m2。
Note：In the present embodiment each power suffered by floating body guide pile with ton (t) for unit, similarly hereinafter.
Parameters are substituted into formula two, then obtain FP≈2.4t/m2。
So, under the no-load condition of ballast tank 130, gravity and hydraulic pressure are considered, floating body guide pile tilts 0.1 degree of needs
Wind-force be at least about 2.41t/m2.Angle of inclination is bigger, then the wind-force needed is bigger.
Generally, the wind-force maximum on sea is only capable of reaching 1t/m2, because every square metre of people when reaching 1t will be by
Blow to and go in the air, the blast more than every square metre of 1t is seldom.It can be seen that floating body guide pile is in the unloaded state, even if plus sea
The active force of wave, can also realize stable position.
When pile body uses as buoy, (such as 1 degree is tilted because it is not strict for stability requirement
Also have no relations, as long as not being shifted over can), above-mentioned pile body can meet to require completely；When the stability requirement to pile body
When comparing strict, for example, as drilling platform, man-made island etc. positioning when, then can be by into ballast tank 130
Increase ballast or increase pile body length are to increase the centre of buoyancy of pile body away from or by setting up first, second flaps to increase
The modes such as seawater resistance, to strengthen the stability of pile body.
As before, ballast tank 130 by loading weight can also further increase weight so that its work to floating body guide pile
Make more stable under state.When the full load of ballast tank 130, the gross mass of floating body guide pile can reach about 200t, now floating body
The draft increase most 50m of guide pile, buoyancy compartment 120 are reduced to 1m, wind area exposed to more than sea level S height
B '=5m2, centre of buoyancy M is 45m apart from bottom b height, and center of gravity G is about 10.5m apart from bottom b height；Then H1'=5.5m,
H2'=34.53m, H3'=30m.
It can be seen that full load, centre of buoyancy M has risen when more unloaded, the distance of center of air pressure and centre of buoyancy in whole pile body
Constant, the distance of center of gravity and centre of buoyancy increases, and the distance of hydraulic pressure center and centre of buoyancy also increases.So, when floating body guide pile tilts 0.1
When spending, it is necessary to wind-force it is bigger, that is to say, that floating body guide pile is more stable in full load.
As above, when floating body guide pile does not have truss, extraordinary stability can be kept, then when it has truss,
Extraordinary stability can still be kept.
To sum up, the effect of in general wind-force and wave, floating body guide pile run-off the straight, embodiments of the invention can not be made
Floating body guide pile can overcome wind-force enough and wave is to its caused lateral external forces as caused by wind-force, so as to realize stabilization
Positioning.
In other embodiments, the gross mass of floating body guide pile can also be other values, but in order to ensure that stably, floating body is fixed
Gross mass during the stake zero load of position should be not less than 50 tons, in addition, the bottom b of floating body guide pile to top a distance can be more than
50 meters, the upper limit of the distance is defined by the sea water advanced of different waters, specifies the seawater in marine site deep as long as meeting that the distance is less than
Degree.
To sum up, the ocean floating body guide pile in the present embodiment utilizes the inline pass of the buoyancy being subject in ocean and gravity
System, realizes effect and the purpose of positioning and fixation of the pile body in ocean, and floating body guide pile can be achieved to fix not without locking bolt
Drift or only fine motion；Easy to use for the anchoring system of prior art, overall structure size is smaller, avoids
Interference between different floating body guide piles, and due to need not be anchored with sea bed, to sea bed fanout free region.
The floating body guide pile of the present embodiment can be applied to oceanographic buoy, beacon positioning is fixed etc., but be not limited only to above-mentioned answer
With.It should be noted that around floating body guide pile be when having loaded article, for example, as ship anchor point and mooring has ship
When, now a part of the loaded article as floating body guide pile, loaded article will increase the wind area of whole floating body guide pile,
Cause floating body guide pile to bear the ability of blast to have declined, it is assumed for example that floating body guide pile original wind area is 150m2, often put down
It is 10t that Fang meter Ke, which bears blast, and the wind area of loaded article is 300m2, such as loaded article wind area and floating body guide pile wind-engaging
When area overlaps, wind area is still 300m2, as wind surface center and the centre of buoyancy are constant, then at this moment every square metre is held
Blast energy then reduces, and has reduced compared to non-loaded situation.Therefore in actual use, it is necessary to which rationally limitation floating body is determined
The load capacity that position stake can be born, ensures its stability.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, this is not being departed from
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
