Detailed Description
As described in the background art, in a shallow and medium water sea area of 30-50m, the required length of the anchor chain 100 is short, so that sufficient restoring force cannot be provided only by its own weight, which causes the floating platform to frequently deviate from the movement range, affects the operation state of the floating wind turbine generator system, and reduces the stability of the floating wind turbine generator system.
If the weight of the anchor chain 100 is increased by increasing the size such as the diameter and length of the anchor chain 100, on the one hand, the manufacturing cost of the anchor chain 100 is drastically increased, and on the other hand, the manufacturer cannot produce the large-diameter anchor chain 100 due to the limited manufacturing capability; therefore, a counterweight 400 is generally added to the lying bottom section 103 of the anchor chain 100, increasing the restoring force of the anchor chain 100.
However, after the plurality of clump weights 400 with uniform weight are arranged on the lying bottom section 103 of the anchor chain 100, the joint of the first clump weight close to the anchor chain overhanging section 102 and the anchor chain 100 is often subjected to a large impact load, so that the anchor chain 100 is easily broken and fails due to fatigue failure, and the durability of the anchor chain 100 is reduced; in addition, when the first counterweight is pulled up, the larger instant impact force at the joint of the anchor chain 100 is not beneficial to the smooth operation of the floating platform, and the sudden change of the posture of the floating platform can be caused, so that the working state of the upper equipment is influenced.
In view of the above, the core of the present invention is to provide a mooring system to improve the stability of the floating wind turbine.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the purpose of description, first, the anchor chain 100 and the fibonacci number series will be described in detail, and as shown in fig. 1 and 3, the anchor chain 100 is formed by sequentially arranging the splash line 101, the overhang line 102, and the lying bottom line 103 from the floating column 200 toward the anchor base 300, a connection point of the splash line 101 to the floating column 200 is set as a first connection point a, a connection point of the splash line 101 to the overhang line 102 is set as a second connection point B, and a connection point of the overhang line 102 to the lying bottom line 103 is set as a third connection point C.
The fibonacci number series, also known as the golden section number series, starts with the third term, each term being equal to the sum of the first two terms.
As shown in fig. 1 to 5, the present invention discloses a mooring system comprising a chain 100 and a plurality of clump weights 400.
Wherein, the anchor chain 100 connects the floating upright column 200 and the anchoring base 300; the plurality of balancing weights 400 are arranged on the anchor chain 100, the balancing weights 400 are arranged at equal intervals on the bottom laying section 103 of the anchor chain 100, the self-floating vertical column 200 faces the direction of the anchoring foundation 300, and the weights of the balancing weights 400 are distributed in a Fibonacci sequence.
When the mooring system provided by the invention is used, the floating upright posts 200 and the anchoring foundation 300 are connected through the anchor chain 100, and as the anchor chain 100 is provided with the plurality of balancing weights 400 which are equidistantly arranged at the bottom laying section 103 of the anchor chain 100, the weight of the anchor chain 100 is increased compared with that of the existing anchor chain 100, the restoring force of the anchor chain 100 is increased, and the deviation degree of a floating type platform is reduced, so that the influence on the running state of the floating type wind generating set is reduced, and the stability of the floating type wind generating set is improved; meanwhile, because the self-floating upright posts 200 face the direction of the anchoring foundation 300, the weights of the multiple balancing weights 400 are distributed in a Fibonacci sequence, therefore, the first balancing weight of the lying bottom section 103 is relatively smaller, the weights of the multiple balancing weights 400 are gradually increased, when the balancing weights 400 are pulled away from the seabed, the instant impact force of the joint of the anchor chain 100 and the balancing weights 400 is smaller, the impact load of the joint of the anchor chain 100 and the balancing weights 400 is reduced, the fatigue durability of the anchor chain 100 is improved, and the posture mutation phenomenon of a floating platform is also reduced, so that the influence on the running state of the floating wind generating set is reduced, and the stability of the floating wind generating set is improved.
In addition, since the above mooring system improves the restoring force of the anchor chain 100 by adding the counter weight 400 to the anchor chain 100, the increase in weight of the anchor chain 100 by increasing the diameter and length of the anchor chain 100 is avoided, and the manufacturing cost and difficulty of the anchor chain 100 are reduced.
The weight member 400 may be in the shape of a sphere, a cube, a cylinder, etc., and any shape that can satisfy the use requirement is within the scope of the present invention; optionally, the weight block 400 provided in the embodiment of the present invention is spherical, so as to reduce the possibility that the weight block 400 is caught by objects such as a seabed, a stone, or a seabed plant during the bottom sinking process, which affects the posture of the anchor chain 100, and reduces the reliability of the mooring system.
The weight member 400 may be made of stainless steel, concrete, waste tires, or the like, as long as the weight member 400 can be distributed in a fibonacci sequence.
As shown in fig. 1 to 3, in one embodiment of the present invention, the weight 400 has a gravity f in sequence from the floating upright 200 toward the anchoring base 3001、f2、f3、f4、f5、f6、f7、f8、f9Because the gravity acceleration values are the same because the counterweights are all located on the seabed in the same environment, the gravity of the multiple counterweights 400 is in direct proportion to the mass of the corresponding counterweights 400, and when the mass of the first counterweight is 500kg, the masses of the subsequent counterweights 400 are 500kg, 1000kg, 1500kg, 2500kg, 4000kg and 7500kg in sequence, and so on according to the Fibonacci series.
Further, the mooring system further comprises a first safety link 500 and a second safety link 600, wherein two ends of the first safety link 500 are respectively connected to two ends of the splash section 101 of the anchor chain 100, namely, the first safety link is connected to the first connection point a and the second connection point B; the two ends of the second safety connecting piece 600 are respectively connected to the two ends of the overhanging section 102 of the anchor chain 100, that is, the second connecting point B and the third connecting point C, so that when the splashing section 101 and the overhanging section 102 are corroded to be broken, the first safety connecting piece 500 and the second safety connecting piece 600 respectively play a role in protection, and the floating upright column 200 is prevented from floating away after the splashing section 101 and the overhanging section 102 are broken, so that the stability of the floating wind turbine generator is reduced.
It should be understood that the first safety connector 500 and the second safety connector 600 may be of steel wire rope, anchor chain or fiber rope type, and the like, and the type of the first safety connector and the second safety connector is within the protection scope of the present invention as long as the type of the first safety connector and the second safety connector can meet the use requirement; optionally, the first safety connection element 500 and the second safety connection element 600 provided by the embodiment of the present invention are both steel wire ropes, and compared with an anchor chain with the same performance, the price of the steel wire ropes is about one third of that of the anchor chain, which not only can satisfy the protection effect on the chain splashing section 101 and the chain overhanging section 102, but also can reduce the cost and improve the benefit.
Moreover, the length of the wire rope connected to the splashing section 101 is greater than the length of the anchor chain 100 of the splashing section 101, and the diameter of the wire rope connected to the splashing section 101 is greater than the diameter of the anchor chain 100 of the splashing section 101, so that the wire rope connected to the splashing section 101 does not bear load when the anchor chain 100 is in normal use, and when the splashing section 101 of the anchor chain 100 is broken, the wire rope connected to the splashing section 101 bears instant impact force, thereby playing a role in protection.
The length of the wire rope connected to the overhanging section 102 is greater than the length of the anchor chain 100 of the overhanging section 102, and the diameter of the wire rope connected to the overhanging section 102 is greater than the diameter of the anchor chain 100 of the overhanging section 102, so that the wire rope connected to the overhanging section 102 does not bear load when the anchor chain 100 is in normal use, and when the overhanging section 102 of the anchor chain 100 is broken, the wire rope connected to the overhanging section 102 bears instant impact force, thereby playing a role in protection.
It should be noted that the anchor chain 100 may be a chain with a stopper or a chain without a stopper, and the present invention is not limited to the above-mentioned chain 100 as long as it can satisfy the use requirement; optionally, the anchor chain 100 provided in the embodiment of the present invention is a non-link anchor chain, and has a longer service life than a link anchor chain, and is less prone to cracking.
Specifically, in a specific embodiment of the present invention, the splash zone 101 is a stepless anchor chain with a diameter of 122mm and a length of 20m, and the steel wire rope connected to the splash zone 101 has a diameter of 132mm and a length of 24 m; the anchor chain of the suspension section 102 is a stepless anchor chain with the diameter of 122mm, the length of the stepless anchor chain is 131m, the diameter of a steel wire rope connected with the suspension section 102 is 132mm, and the length of the steel wire rope is 24 m; the anchor chain of the lying bottom section 103 adopts a stepless anchor chain with the diameter of 208mm and the length of 280 mm.
It should be understood that the present invention does not specifically limit the spacing distance between the adjacent weights 400 of the lying bottom section 103, and in practical applications, the spacing distance between the adjacent weights 400 can be adaptively adjusted; optionally, the distance between adjacent counterweights 400 in the present invention is 4-8 m.
Further, a weight 700 may be provided at catenary section 102 of chain to further increase the added weight of chain 100 and increase its return force.
It should be noted that the number of the above-mentioned suspension weights 700 is not specifically limited, and optionally, the number of the suspension weights 700 provided by the present invention is 1 to 6; and the weight of the suspended weight block 700 does not exceed the weight of the counterweight block 400, preventing the weight of the suspended weight block 700 from being too large, so that the joint of the anchor chain 100 and the suspended weight block 700 is subjected to sudden impact force, reducing the fatigue durability of the anchor chain 100 and shortening the service life of the anchor chain.
In addition, the invention also discloses a floating wind power generation system, which comprises the mooring system, so that all technical effects of the mooring system are considered, and the details are not repeated herein.
