Description

Technical Field

[0001] The present invention relates to the technical field of offshore mooring systems, and more particularly to a mooring system. Background Art

[0002] Ocean buoys are generally fixed to designated locations in the sea using buoy mooring devices. Traditional buoy mooring devices mainly use steel anchor chains to connect buoys and iron anchors to fix the position of buoys. However, due to the high cost of steel anchor chains and the tendency to sink to the seabed after being released, making recovery difficult, mooring devices that combine part of the anchor chain and part of the rope are generally used for fixing.

[0003] However, the existing mooring device combining anchor chain and rope is generally fixed in an S-shaped connection mode, that is, the first end of the anchor chain is connected to the buoy, and the second end of the anchor chain is vertical to the sea water due to gravity; the first end of the rope is connected to the second end of the anchor chain, and the other end is connected to the anchor on the seabed; but in order to quickly find the position of the rope during secondary use, a buoy is connected to the middle area of ​​the rope so that the position of the rope can be found through the buoy. Because the buoy pulls the middle area of ​​the rope to the sea surface, the rope is distributed in an S shape in the sea. When such a setting method is used in the deep sea, on the one hand, the actual required length of the rope will far exceed the distance between the anchor chain and the anchor, resulting in the prefabricated length of the rope not meeting the actual required length requirements, and also resulting in a high cost of the rope. More importantly, since the position of the buoy is located in the middle area of ​​the rope, the distance between the position of the buoy and the first end of the rope is long. When it is used for the second time, it is difficult to find the specific position of the first end of the rope, resulting in inconvenience in use. Moreover, due to the pulling force of the buoy on the middle and rear sections of the rope, the grip of the anchor is not stable enough, the rope is also worn and has a short service life. Summary of the invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a mooring system for solving the problem of how to stably fix the buoy and reduce rope wear.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A mooring system used to secure a buoy, including anchor chains, ropes and anchors.

[0007] The rope is divided into a front middle part and a middle rear part, the middle rear part of the rope is fixedly connected to the iron anchor, the front middle part of the rope is connected between the anchor chain and the iron anchor, and the bottom end of the front middle part of the rope is fixedly connected to the iron anchor, the top end of the front middle part of the rope is detachably connected to one end of the anchor chain, and the other end of the anchor chain is fixedly connected to the buoy;

[0008] It also includes a plurality of counterweight blocks, which are fixed on the rope between the anchor chain and the iron anchor and are used to counterweight the rope so that the front middle part of the rope is in the shape of a parabola.

[0009] In this technical solution, by setting a counterweight, the rope is connected between the anchor chain and the iron anchor in a parabolic form, which can make the rope better adapt to the height change from the seabed to the sea surface, and then more stably fixedly connected with the anchor chain and the iron anchor. Specifically, the rope is connected between the anchor chain and the iron anchor in a parabolic form. On the one hand, because the rope is connected to the iron anchor in a way that is infinitely close to the seabed, it can play a buffering role on the iron anchor, avoiding the rigid stretching between the iron anchor and the rope, causing the iron anchor to be not stable enough or the rope to be easily worn; on the other hand, the parabolic form of the rope allows the rope to connect to the anchor chain in a slowly upward manner, and then connect to the buoy, which can better buffer the impact of seawater disturbance on the rope, thereby making the connection between the anchor chain and the rope more stable and less worn; and the buoy can also be more stable to avoid excessive shaking.

[0010] Moreover, fixing the rope in a parabola form can shorten the required rope length at the same sea depth compared to the traditional S-shaped method, thereby saving costs.

[0011] Furthermore, the rope is a polypropylene rope, a nylon rope or a high-strength polymer rope. The length of the rope is determined according to the water depth, the maximum wave height, the maximum tidal range, the astronomical high tide, and the rope length required for lifting.

[0012] Furthermore, the anchor chain is a steel anchor chain, which can effectively fix the buoy and effectively resist mechanical wear caused by sea water fluctuations.

[0013] Furthermore, the number and weight of the counterweights can be set according to the wave conditions to ensure that the rope is connected between the anchor and the anchor chain in a parabolic form.

[0014] In one embodiment, a buoy is provided on the middle and rear part of the rope for pulling up the rope and making the middle and rear part of the rope be in a straight-line shape, close to the seabed and suspended above the seabed and connected to the front and middle part of the rope.

[0015] Specifically, the form in which the rope is close to the seabed and suspended above the seabed means that the rope is close to the seabed but does not contact the seabed. This form can not only ensure the stability of the middle and rear parts of the rope, but also effectively avoid friction between the rope and the seabed.

[0016] In one embodiment, the anchors include at least two groups, which are sequentially arranged at the middle and rear part of the rope, and are divided into a bottom anchor arranged at the bottom of the rope and a middle anchor arranged between the bottom anchor and the counterweight block, and the middle anchor includes at least one group.

[0017] Preferably, the buoy is arranged at the connection position between the middle iron anchor and the rope.

[0018] By setting the middle iron anchor, the position of the rope can be better fixed, so that the rope can fix the buoy more firmly. And setting the middle iron anchor can also increase the grip and make the bottom of the rope more stable. Furthermore, by using the middle iron anchor and the buoy, the middle and rear parts of the rope are arranged in a straight line, which not only avoids the friction between the rope and the seabed and causes wear, but also makes the middle and rear parts of the rope more firmly fixed and more resistant to the disturbance of sea water.

[0019] In one embodiment, a four-point connector is provided on the middle and rear part of the rope, and the rope is divided into several small sections by the four-point connector. The four-point connector is provided with at least four connection positions, including two horizontal connection positions arranged in the horizontal direction and an upper connection position and a lower connection position arranged perpendicular to the horizontal connection positions, and the horizontal connection positions respectively connect two adjacent small sections of the rope; the float is connected to the upper connection position; and the middle iron anchor is connected to the lower connection position.

[0020] Since the position where the rope is fixed to the middle iron anchor is subject to greater wear, the setting of a four-point connector can effectively avoid rope wear and can also make it more convenient to fix the middle iron anchor and the buoy at the same position, so as to achieve a horizontal suspension state of the rope while making the force on the rope more uniform; in addition, the setting of the four-point connector is also convenient for increasing or shortening the length of the rope so that the rope can adapt to different deep water depth requirements.

[0021] In one embodiment, the distance between every two adjacent four-site connectors is consistent.

[0022] The distance between two adjacent four-point connectors is consistent, which can more effectively ensure that the force on the middle and rear part of the rope is stable and uniform.

[0023] In one embodiment, the rope between two adjacent four-position connectors is in a straight line.

[0024] In one of the embodiments, a first connecting member is provided at the connection position between the anchor and the rope, a second connecting member is provided at the connection position between the float and the rope, and the first connecting member and / or the second connecting member are provided with a plurality of length adjustment gears.

[0025] By setting the first connecting piece, the iron anchor can be prevented from directly stretching the rope, which would cause insufficient stability. The first connecting piece can also buffer the stretching between the iron anchor and the rope, which is more conducive to ensuring the stability and service life of the rope, and can also effectively ensure that the middle and rear parts of the rope are set in a horizontal suspended state. By setting the length adjustment gear to facilitate adjusting the length of the first connecting piece, it is more conducive to ensuring that the rope is in a horizontal suspended state.

[0026] Preferably, the first connecting member and the second connecting member are steel anchor chains.

[0027] In one embodiment, a three-point connector is provided on the front middle part of the rope, and the three-point connector is arranged at the connection position between the rope and the counterweight block, and at least three connection positions are provided on the three-point connector, including a first connection position for connecting the two ends of the rope, a second connection position and a third connection position for connecting the counterweight block, and the third connection position is arranged downward.

[0028] By setting a three-point connector, the wear of the rope by the counterweight can be effectively avoided.

[0029] In one of the embodiments, a third connecting member is provided at the connection position between the counterweight block and the rope, and the third connecting member corresponds to the counterweight block one by one. The closer the third connecting member is arranged to the front of the rope, the longer its length is, so as to adapt to the change in the distance between the parabolic rope and the counterweight block.

[0030] The third connecting piece is provided to connect the counterweight and the rope, and the front middle portion of the rope is provided in a parabolic shape. The length change of the third connecting piece is also conducive to adapting to the change of the undulation of the sea water, so that the rope is more stable.

[0031] In one embodiment, the top of the rope can be selectively connected to a buoy. When the connection between the anchor chain and the rope is disconnected, the top of the rope is connected to the buoy, and the buoy floats on the sea surface after being connected to the rope.

[0032] In this technical solution, the setting of the float helps people to quickly find the positioning point of the buoy during the secondary positioning. Specifically, when the buoy needs to return to the shore, the connection between the anchor chain and the rope needs to be released. At this time, although the rope can be suspended in the sea, if it needs to be used again, it still needs to be searched within a certain range. By fixing a float on the rope and making the float float on the sea surface, the position of the float is the position where the buoy is fixed again, and then the fixed position of the buoy can be quickly found, which is more in line with user needs.

[0033] Further, the top of the rope is provided with a buckling device for fastening and fixing with an anchor chain or a floating ball. Further, the floating ball can also be provided with an anchor chain or other connecting pieces for connecting and fixing with the rope.

[0034] In one of the embodiments, the counterweight blocks include two groups, and the iron anchors are Hall anchors; the middle iron anchors include two groups, and the buoys are arranged in a one-to-one correspondence with the middle iron anchors.

[0035] By setting two sets of counterweights and the middle iron anchor, it is conducive to more stable fixing of the rope, so that the buoy's tensile resistance and anti-displacement ability are stronger. The Hall anchor grip can better adhere to the ground and form a strong horizontal grip.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] The mooring system of the present invention limits the shape of the rope by arranging a counterweight block and a middle iron anchor, so that the rope can be more adaptable to waves; by arranging a four-point connector and a three-point connector, the wear between the rope and the counterweight block and the middle iron anchor can be effectively avoided; by arranging a second connecting piece and a buoy, it is effectively ensured that the middle and rear part of the rope is arranged in a horizontal suspended state, so that the grip of the rope is more stable and the wear of the rope and the bottom surface is avoided; by arranging multiple groups of iron anchors, it can also be ensured that the mooring system has a strong horizontal grip.

[0038] The present invention also has the beneficial effect of facilitating and quickly finding the buoy positioning position by selectively arranging a float at the top of the rope.

[0039] The mooring system of the present invention can be widely used in various buoy fixation, wind power installations, marine ranch equipment-type aquaculture and other fields, and has strong stability and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0044] Example 1

[0045] like Figure 1As shown, this embodiment discloses a mooring system for fixing a buoy 400, including an anchor chain 100, a rope 200 and an iron anchor, wherein the rope 200 is divided into a front middle part and a middle rear part, the middle rear part of the rope 200 is fixedly connected to the iron anchor, the front middle part of the rope 200 is connected between the anchor 100 and the iron anchor, and the bottom end of the front middle part of the rope 200 is fixedly connected to the iron anchor, the top end of the front middle part of the rope 200 is detachably connected to one end of the anchor chain 100, and the other end of the anchor chain 100 is fixedly connected to the buoy 400; so that the rope 200 is pulled by the iron anchor to fix the buoy 400. When the buoy 400 needs to be driven back to the shore, the buoy 400 can be released by releasing the connection between the top of the rope 200 and the anchor chain 100.

[0046] Furthermore, the mooring system of this embodiment is further provided with n sets of counterweights 500. Specifically, the n sets of counterweights 500 are sequentially fixed on the rope 200 between the anchor chain 100 and the iron anchor, and are used to counterweight the rope 200 so that the front middle portion of the rope 200 is connected between the anchor chain 100 and the iron anchor in a parabolic form. The n sets of counterweights 500 are arranged in order from the top of the rope 200 to the middle and rear portion of the rope 200, and are sequentially named as the first counterweight, the second counterweight, and the nth counterweight.

[0047] Furthermore, in order to more firmly fix the rope 200, resist the impact of waves, and provide greater grip, the present technical solution also provides a bottom anchor 310 and a middle anchor 320 provided between the bottom anchor 310 and the counterweight 500 at the middle and rear part of the rope 200. Specifically, in the present embodiment, the middle anchor 320 includes i groups, and the i groups of middle anchors are provided in sequence from the front middle part of the rope 200 to the middle and rear part of the rope 200, and are named as the first middle anchor, the second middle anchor, ... the i-th middle anchor.

[0048] Furthermore, in order to prevent the middle and rear part of the rope 200 from contacting and rubbing against the seabed, thereby affecting its performance and life, the present technical solution also provides several groups of buoys 600 on the middle and rear part of the rope 200, so that the middle and rear part of the rope 200 is in a straight-line shape, close to the seabed and suspended above the seabed, connected to the front and middle part of the rope 200.

[0049] By arranging the floating balls 600, the lowest end of the rope 200 can also be brought up to avoid friction between the lowest end of the rope 200 and the seabed. Specifically, the number of floating balls corresponds to the number of middle iron anchors.

[0050] like Figure 1 and Figure 2As shown, further, a four-point connector 700 is provided at the connection position between the rope 200 and the middle iron anchor 320, and the middle and rear part of the rope 200 is divided into several small sections, and two adjacent small sections of the rope are connected by the four-point connector 700. Specifically, the four-point connector 700 is provided with at least four connection positions, including two horizontal connection positions arranged in the horizontal direction and an upper connection position and a lower connection position arranged perpendicular to the horizontal connection position. Among them, the horizontal connection position connects two adjacent small sections of the rope 200 respectively; the upper connection position is connected to the floating ball 600 to fix the position of the floating ball 600; the lower connection position is connected to the middle iron anchor 320 to fix the middle iron anchor 320.

[0051] Among them, by setting the buoy 600 on the four-point connector 700, the buoy 600 can be better fixed, and the friction of the buoy 600 on the rope 200 can be avoided. In addition, the buoy 600 is set on the middle iron anchor 320, and the rope 200 can be better pulled up, avoiding the friction between the rope 200 and the seabed, which affects the service life. By setting the four-point connector 700, the buoy 600 and the middle iron anchor 320 can be effectively fixed, and the friction on the rope 200 can also be effectively avoided, thereby improving the service life of the rope 200. Preferably, the four-point connector 700 is detachably connected to the rope 200, the buoy 600 and the middle iron anchor 320, respectively, for easy replacement.

[0052] Furthermore, in order to make the rope 200 between adjacent anchors bear force more evenly, the four-point connectors 700 are evenly distributed on the rope 200. That is, the length of the rope 200 between adjacent four-point connectors 700 is consistent.

[0053] Furthermore, in order to make the iron anchor hold the seabed more firmly, the iron anchor is further provided with a first connecting member 810, so as to be connected to the rope 200 through the first connecting member 810. Preferably, the first connecting member 810 is a steel anchor chain. By providing the first connecting member 810, the direct impact of the sea waves on the rope 200 and the iron anchor can be better resisted, so as to play a better fixing and buffering role.

[0054] Furthermore, a second connector 820 may be provided between the connection between the float 600 and the rope 200 to better fix the float 600. Furthermore, the first connector 810 and the second connector 820 may be provided with a plurality of length adjustment gears to adjust the length of the first connector 810 and the third connector 820.

[0055] like Figure 1 and Figure 3As shown, further, a three-point connector 900 is provided at the connection position between the rope 200 and the counterweight 500. The three-point connector 900 also divides the rope 200 into several small sections and connects the rope 200 and the counterweight 500, so that the counterweight 500 is more firmly fixed. The three-point connector 900 includes three connection positions, namely, a first connection position and a second connection position for connecting the rope 200, and a third connection position for connecting the counterweight 500. By providing the three-point connector 900, the counterweight 500 can be better connected and fixed, and the wear of the rope 200 by the counterweight 500 can also be effectively avoided.

[0056] Furthermore, each set of counterweights 500 is provided with a third connector 830, and is connected to the three-point connector 900 on the rope 200 through the third connector 830. Specifically, the third connector 830 is a steel anchor chain, wherein the anchor chain 100 on the first counterweight is longer than the anchor chain on the second counterweight, so that the parabolic form of the front half of the rope 200 can be better ensured, and the setting of the rope 200 can also be closer to the wave form of the waves, so that the rope 200 is more stable and the buoy 400 is more stable.

[0057] Among them, the first connecting member 810, the third connecting member 830 and the third connecting member 830 are preferably steel anchor chains with gears.

[0058] Further, the rope 200 is a polypropylene rope, a nylon rope or a high-strength polymer rope. The length of the rope 200 is determined according to the water depth, the maximum wave height, the maximum tidal range, the astronomical high tide, and the rope length required for lifting.

[0059] Furthermore, the anchor chain 100 is a steel anchor chain, which can effectively fix the buoy 400 and effectively resist mechanical wear caused by sea water fluctuations.

[0060] Furthermore, the number and weight of the counterweights 500 can be set according to the wave conditions to ensure that the rope 200 is connected between the anchor and the anchor chain 100 in a parabolic form.

[0061] Specifically, in actual operation, when the connection between the anchor chain 100 and the rope 200 is untied, a buoy can be fixed at the top of the rope 200, and the buoy floats on the sea surface after being connected to the rope 200. When the buoy 400 needs to be fixed again, the positioning point of the buoy 400 can be quickly found through the buoy.

[0062] Furthermore, a buckling device may be provided at the top of the rope 200 for fast buckling and fixing with the anchor chain 100 or the buoy.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
