Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
One embodiment of the present of invention provide a kind of buoyancy aid work pile, with reference to Fig. 1, comprise joint pin 110 and are connected to the buoyancy compartment 120 at two ends and the ballast tank 130 of joint pin 110.Buoyancy compartment 120 has disconnected first cavity 121 with seawater; Ballast tank 130 defines a cavity 131, and when buoyancy aid work pile works in the seawater, the cavity 131 of ballast tank 130 is communicated with seawater; Also comprise truss 160, be fixedly connected between buoyancy compartment 120 and joint pin 110, or be fixedly connected between ballast tank 130 and joint pin 110, or joint pin 110 is separated into two sections vertically and is fixedly connected between two sections of joint pins 110, truss 160 can allow ocean current to pass.Here " buoyancy aid ", refers to and can suspend in water to sink, but the object that also can not drift about; " buoyancy aid " is different from " drift body ", and " drift body " refers to and float on the water surface, and can with the object of External Force Acting drift.
Buoyancy compartment 120 is not communicated with seawater, and the first cavity 121 referring to buoyancy compartment is not communicated with seawater, and it can be closed, also can be communicated with ambient atmosphere.
With reference to Fig. 1, buoyancy aid work pile 100 has top a and bottom b, and top a is positioned at buoyancy compartment 120 one end away from joint pin 110, and bottom b is positioned at the other end of buoyancy aid work pile relative to top a; The displacement (when namely buoyancy compartment is immersed in seawater completely, the quality of the water arranged) of buoyancy compartment 120 is not less than the total mass of buoyancy aid work pile, and the total mass of buoyancy aid work pile is not less than 50 tons.The displacement of buoyancy compartment 120 and buoyancy compartment 120 immerse the quality of the water arranged in seawater completely, here quality and displacement all represent (1 ton=1000 kilograms) with tonnage, therefore, when buoyancy aid work pile is arranged in seawater, suffered buoyancy can offset gravity, and therefore buoyancy aid work pile can suspend in the seawater.When described buoyancy aid work pile works in the seawater, the leaning angle produced under external physical force effect is not more than 1 degree, in the application scenario requiring stability requirement strict, can also by changing pile parameter, the leaning angle that described buoyancy aid work pile is produced under external physical force effect is not more than 0.1 degree.
The displacement of buoyancy compartment 120 is not less than the total mass of buoyancy aid work pile, and quality here and displacement all represent with tonnage.Therefore, when buoyancy aid work pile is arranged in seawater, suffered buoyancy can offset gravity, and therefore buoyancy aid work pile can suspend in the seawater.In certain embodiments, the total displacement of buoyancy compartment 120 is greater than 200t (1t=1000Kg).In certain embodiments, do not having in ballasted situation, the total mass that the quality of buoyancy compartment 120 accounts for buoyancy aid work pile is no more than 1/3.The shape of buoyancy compartment 120 can be cube shaped, cuboid.When buoyancy aid work pile works in the seawater, have centre of buoyancy M and center of gravity G, center of gravity G is between centre of buoyancy M and bottom b.The centre of buoyancy M of buoyancy compartment 120 will as far as possible away from the center of gravity of pile body, and its displacement wants large, comprehensively these two conditions, it is foursquare rectangular structure that the structure of buoyancy compartment 120 is preferably cross section, and the height of cuboid is greater than the width in cross section, namely the height of buoyancy compartment 120 should be suitably larger.
Further, full quality light (density is less than water) can be filled and the material do not absorbed water in first cavity 121 of buoyancy compartment 120, can avoid like this buoyancy compartment 120 be corroded or outside destroy time, avoid seawater or other materials to enter the first cavity 121, ensure the function of buoyancy compartment 120.Quality gently and its quality of the material do not absorbed water relative to negligible buoyancy aid work pile, as an embodiment, quality gently and the material do not absorbed water, can be such as polyvinylchloride, foam etc. organic material.
With reference to Fig. 3, consider the impact of ocean current, be provided with truss 160 between buoyancy compartment and joint pin, when buoyancy aid work pile works in the seawater, ocean current energy passes in truss 160.Truss 160 is positioned at buoyancy aid work pile along position corresponding with ocean current on prolonging direction, the length of truss 160 is not less than the degree of depth of ocean current or basic suitable with the ocean current degree of depth, that is the length of truss 160 is generally by specifying the ocean current degree of depth in marine site to determine and being preferably not less than the ocean current degree of depth of specifying marine site, but consider the actual ocean current degree of depth and cost control, the length of truss 160 is no more than 50 meters, and the length of truss 160 refers to its height when pile body works in the seawater.
When sea is subject to wind-force effect, surface seawater sport forms stormy waves, even if when wind-force is maximum, the surface seawater degree of depth that it can affect is typically not more than 10 meters, and therefore the center of gravity G of buoyancy aid work pile will lower than the stormy waves degree of depth.The distance of center of gravity G distance sea level S should be greater than 10 meters, and the distance between center of gravity G and centre of buoyancy M should be greater than 8 meters.In addition, in order to avoid ocean current impact, center of gravity G also should avoid the position of truss 160.In certain embodiments, suppose that truss 160 is 50 meters, and truss 160 is between buoyancy compartment 120 and joint pin 110, then the center of gravity of described buoyancy aid work pile will reach more than 60 meters apart from sea level S, pile body total length reaches more than 100 meters, the distance of the centre of buoyancy M of buoyancy aid work pile in buoyancy compartment 120 and between centre of buoyancy M and center of gravity G is not less than 58 meters, so center of gravity G with the distance of sea level S larger than truss 160 length more than 10 meters, larger than truss 160 length more than 8 meters of the distance between centre of buoyancy M and center of gravity G.
With reference to Fig. 1 composition graphs 2, truss 160 can be made up of many vertical first purlin posts 161, and have space between many first purlin posts 161, one end of many first purlin posts 161 is connected with described buoyancy compartment 120, and the other end is connected with described joint pin 110.Connected by one or more second purlin posts 162 between adjacent first purlin post 161.The lateral dimension of the every root in many first purlin post 161, second purlin posts 162 is less than joint pin far away, namely thin more than joint pin 110, when buoyancy aid work pile works in the seawater, ocean current energy passes from the space between many first purlin post 161, second purlin posts 162.The lateral dimension of overall truss 160, namely perpendicular to the size of the prolonging direction of joint pin 110, can be identical with the lateral dimension of joint pin 110.Because every root first purlin post 161, second purlin post 162 of truss 160 is thinner, in order to ensure can not to break under ocean current or stormy waves impact, the intensity of every root first purlin post 161, second purlin post 162 is enough high.
Further, the sidewall of ballast tank 130 can also be provided with through hole (mark), the quantity of through hole is too much unsuitable, general one to two, the size of through hole is also unsuitable excessive, as long as seawater can be made to enter ballast tank 130 smoothly and the cavity 131 making ballast tank 130 limit is communicated with extraneous seawater.In certain embodiments, through hole can also adopt sealing member (not shown) to seal, to isolate cavity 131 and the external world.Like this in transportation, ballast tank 130 can seal, so that transport.Ballast tank 130 can be unloaded, also can increase weight to buoyancy aid work pile by adding loads, the center of gravity G of buoyancy aid work pile is dragged down further, to increase centre of buoyancy apart from (distance namely between center of gravity G and centre of buoyancy M), therefore the length of joint pin 110 does not need to arrange very long, and buoyancy aid work pile in the seawater also can stable position.The shape of ballast tank 130 can adopt any shape, such as square, cylindrical etc.The quality of ballast tank 130 will be tried one's best greatly, and volume is little.In certain embodiments, when ballast tank 130 is unloaded, ballast tank 130 is greater than 2/3 of whole pile quality with the quality sum of joint pin 110; Ballast tank 130 at full load, ballast tank 130 accounts for the proportion of the quality of whole pile body more than 1/2 with the quality sum of ballast.
Time unloaded, the proportion that the quality of joint pin 110 accounts for buoyancy aid work pile total mass is greater than 1/3.In certain embodiments, joint pin 110 along the uniform quality of its prolonging direction, even intensity.Buoyancy aid work pile is when seawater works, and in vertical state, namely when without stormy waves or without ocean current, buoyancy aid work pile is substantially vertical with sea level S.Buoyancy aid work pile 100 must have enough quality to stablize.Because in embodiments of the invention, the bottom of pile body has ballast tank 130, by filling ballast in ballast tank 130, therefore joint pin 110 need not have the requirement that very large length also may meet quality, in certain embodiments, if buoyancy aid work pile 100 is steel structure, namely buoyancy compartment 120 and joint pin 110 are corrosion-resistant steel, in order to realize stable position, the width that such as can be arranged on joint pin 110 is in 3 meters of situations, and the length of joint pin 110 is greater than 35 meters.

When such as front buoyancy aid work pile has deposit cabin 150 time, the first resistance piece 111 and the second resistance piece 112 also can be set, be not described in detail in this.
As an embodiment, location, ocean 100 entirety can be steel structure, that is: joint pin 110, buoyancy compartment 120 and ballast tank 130, truss 160 are steel structure.
The principle of work of the buoyancy aid work pile of the embodiment of the present invention is as follows, when buoyancy aid work pile (is not namely parallel to the application force in the direction of sea level S by lateral external forces, the power such as applied by wind or wave, the motion of ocean current slowly, its power applied buoyancy aid work pile is relative to negligible wind-force) effect time, it, perpendicular to sea level S, is in initial condition; When being subject to lateral external forces effect, lateral external forces will produce tilting moment, and according to Ship Statics, the gravity of buoyancy aid work pile self will produce righting moment; In addition, the pile body part be under water is also subject to the effect of hydraulic pressure (pressure of seawater), and hydraulic pressure produces resistance torque.Righting moment and resistance torque all can resist tilting moment, impel buoyancy aid work pile to return back to virgin state.
When only considering wind-force effect, suppose that buoyancy aid work pile tilts 0.1 ° (angle), it is subject to the application force of wind-force, gravity and hydraulic pressure (only considering the hydraulic pressure of centre of buoyancy M to bottom b part here) three aspects, and composition graphs 1, concrete force analysis is as follows.
Be exposed to the part of sea level more than S in wind-force effect to buoyancy aid work pile, the center of definition wind-force effect is wind-force center P; The center of pressure of seawater is hydraulic pressure center.

Through calculating, do not have the situation of truss in pile body compared with the situation having truss, the weight of pile body is smaller, and draft is lower, and the area exposed across the sea is then larger, and the distance between pile body center of gravity and centre of buoyancy is also smaller.That is, if according to formula one, do not have the situation of truss in pile body compared with the situation having truss, tilting moment is larger, and righting moment then can be smaller, and that is, when having truss, the stability of pile body is than better when not having a truss.
When lower surface analysis buoyancy aid work pile does not have a truss, its stressing conditions:
Suppose that the parameters of buoyancy aid work pile is as follows: the distance of top a to bottom b is 51m; The total mass of buoyancy aid work pile is about 60t; The cross-sectional plane of joint pin, ballast tank and buoyancy compartment is square, and joint pin is set to the cylinder of transversal face width 3m, high 38m, and buoyancy compartment 120 is set to the cylinder of transversal face width 5m, high 11m, and ballast tank 130 is set to transversal face width 4m, the cylinder of high 2m; Buoyancy compartment, joint pin, ballast tank are all made with the steel of same size.
When ballast tank 130 is unloaded, with reference to Fig. 2, buoyancy aid work pile draft is about 43m, and buoyancy compartment 120 is exposed to sea level more than S and is highly about 8m, calculates:
Area exposed to the wind B=40m
2;
The height of center of gravity G distance bottom b is about 32.5m; Then the height of centre of buoyancy M distance bottom b is 41.5m, and the height of hydraulic pressure centre distance bottom b is about 14.3m.
Then H
1=5.5m, H
2=8.5m, H
3=27.2m;
Parameters is substituted into formula one, then obtain F
p≈ 0.01t/m
2.
Note: in the present embodiment each power suffered by buoyancy aid work pile with ton (t) for unit, lower with.
Parameters is substituted into formula two, then obtain F
p≈ 2.4t/m
2.
So, under ballast tank 130 no-load condition, consider gravity and hydraulic pressure, buoyancy aid work pile inclination 0.1 degree of wind-force needed is at least about 2.41t/m
2.Angle of inclination is larger, then the wind-force needed is larger.
Generally, the wind-force on sea is maximum only can reach 1t/m
2, because people will be blown to and goes in the air when every sq m arrives 1t, the blast being greater than every sq m 1t is little.Visible buoyancy aid work pile in the unloaded state, even if add the application force of wave, also can realize stable position.
When pile body uses as buoy time, due to its for stability requirement be not strict (such as tilt 1 degree and also have no relations, only otherwise occur to be shifted just can), above-mentioned pile body can meet the demands completely; When stricter to the stability requirement of pile body time, such as, when it can be used as the location of creeping into platform, artificial island etc., then can by increasing ballast or increase pile body length to increase the centre of buoyancy distance of pile body in ballast tank 130, or by setting up first, second flaps to increase the modes such as seawater resistance, strengthen the stability of pile body.
As front, ballast tank 130 can also by adding loads and carry out increasing weight further to buoyancy aid work pile thus more stable under making its mode of operation.When ballast tank 130 at full load, the total mass of buoyancy aid work pile can reach about 200t, now the draft increase most 50m of buoyancy aid work pile, and the height that buoyancy compartment 120 is exposed to sea level more than S is reduced to 1m, area exposed to the wind B '=5m
2, the height of centre of buoyancy M distance bottom b is that 45m, center of gravity G are about 10.5m apart from the height of bottom b; Then H
1'=5.5m, H
2'=34.53m, H
3'=30m.
Can see, at full load, rise to some extent when centre of buoyancy M is more unloaded, the distance of whole pile body Wind pressure center and centre of buoyancy is constant, and 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 buoyancy aid work pile inclination 0.1 degree, the wind-force of needs is larger, and that is buoyancy aid work pile is more stable at full load.
As above, when buoyancy aid work pile does not have a truss, extraordinary stability can be kept, so when it has truss, still can keep extraordinary stability.
To sum up, general wind-force and the effect of wave, cannot make the run-off the straight of buoyancy aid work pile, and the buoyancy aid work pile of embodiments of the invention enough can overcome the lateral external forces that wind-force and the wave that produced by wind-force produce it, thus realizes stable position.
In other embodiments, the total mass of buoyancy aid work pile also can be other values, but in order to ensure to stablize, total mass when buoyancy aid work pile is unloaded should be not less than 50 tons, in addition, the distance of the bottom b to top a of buoyancy aid work pile can be greater than 50 meters, and the upper limit of this distance is as the criterion with the sea water advanced of different waters, as long as meet this distance to be less than the sea water advanced of appointment marine site.
To sum up, ocean buoyancy aid work pile in the present embodiment utilizes the inside-connecting relation of buoyancy and the gravity be subject in ocean, realize the location of pile body in ocean and fixing effect and object, buoyancy aid work pile need not can realize fixingly not drifting about or only having fine motion by locking bolt; Relative to the mooring system of prior art, easy to use, integral structure size is less, avoids the interference between different buoyancy aid work pile, and owing to not needing to be anchored with sea bed, to sea bed fanout free region.
The buoyancy aid work pile of the present embodiment can be applicable to oceanographic buoy, beacon location is fixed, but is not limited only to above-mentioned application.It should be noted that, be when having loaded article around buoyancy aid work pile, such as, when as boats and ships anchor point, mooring has boats and ships, now loaded article is as a part of buoyancy aid work pile, loaded article will increase the area exposed to the wind of whole buoyancy aid work pile, the ability causing buoyancy aid work pile to bear blast declines to some extent, such as, suppose that the former area exposed to the wind of buoyancy aid work pile is 150m
2, it is 10t that every sq m can bear blast, and the area exposed to the wind of loaded article is 300m
2, as loaded article area exposed to the wind and buoyancy aid work pile area exposed to the wind overlap time, area exposed to the wind is still 300m
2, as wind surface center and center of buoyance constant, so at this moment every sq m holds blast energy and then reduces, and reduces to some extent compared to non-loaded situation.Therefore, when reality uses, the load capacity needing reasonable limits buoyancy aid work pile to bear, ensures its stability.
Although the present invention discloses as above, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
