Description

Technical Field

[0001] The present invention relates to the technical field of offshore mooring structures, and more specifically, to a four-point connector and a mooring system provided with the same. Background Art

[0002] Ocean buoys are generally fixed at designated positions in the sea area by buoy mooring devices. Traditional buoy mooring devices mainly connect the buoy and the iron anchor through steel anchor chains, thereby fixing the position of the buoy. However, due to the high cost of steel anchor chains and the fact that they are likely to sink to the bottom of the sea after being unfixed, making recovery difficult, a mooring device combining part of the anchor chain and part of the rope is generally used for fixation.

[0003] However, the texture of the rope is always not as hard as that of the steel anchor chain, so it is easily worn. For example, in the prior art, the bottom end of the rope is directly connected to the iron anchor, and the iron anchor is inserted into the seabed. On the one hand, the connection position between the rope and the iron anchor is easily worn due to the impact of sea waves. On the other hand, the iron anchor is also easily loosened by the pulling of the rope, resulting in instability. Moreover, if the iron anchor sinks deeper, the rope is also easily rubbed against the seabed, leading to more damage.

[0004] In addition, the existing mooring device combining the anchor chain and the rope generally uses an S-shaped connection method for fixation, that is, the first end of the anchor chain is connected to the buoy, and the second end of the anchor chain hangs vertically into 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 iron anchor on the seabed; but in order to quickly find the position of the rope during secondary use, a floating ball is connected in the middle area of the rope, so as to find the position of the rope through the floating ball. Since the floating ball pulls up the middle area of the rope towards the sea surface, the rope is distributed in an S shape in the sea. Such a setting method, when used in deep sea, on the one hand, will make the actual required length of the rope far exceed the distance between the anchor chain and the iron anchor, resulting in the prefabricated length of the rope not meeting the actual required length requirements and also leading to a high cost of the rope. More importantly, since the position where the floating ball is set is in the middle area of the rope, the distance between the position of the floating ball and the first end of the rope is relatively long, making it difficult to find the specific position of the first end of the rope during secondary use, resulting in inconvenience in use. Summary of the Invention

[0005] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art, and provides a four-point connector for solving the problem that the rope is easily worn.

[0006] The present invention also provides a mooring system, and the mooring system of the present technical solution has the beneficial effects of stably fixing the buoy and reducing the wear of the rope.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A four-point connector is provided on a mooring system, including: a four-eye plate and connecting parts arranged in the directions of the four vertices of the four-eye plate, namely a left connecting part and a right connecting part arranged in the horizontal direction, and an upper connecting part and a lower connecting part arranged in the vertical direction. The four-eye plate includes a columnar body and a plate-shaped body arranged perpendicular to each other, and a reinforcing plate is provided between the columnar body and the plate-shaped body. The reinforcing plate is perpendicular to the columnar body and the plate-shaped body respectively, and the columnar body, the plate-shaped body and the reinforcing plate are integrally formed.

[0009] In this technical solution, by providing a four-point connector on the mooring system to facilitate the connection of various components on the mooring system, including ropes, anchors or floats, etc., on the one hand, the connection position is made more concise, and on the other hand, it can effectively avoid the wear of the rope by metal objects, resulting in affecting the service life of the rope. Specifically, for the four-point connector of this technical solution, by setting the four-eye plate, the stability of the connection position can be effectively improved, making the mooring system more adaptable at sea. Specifically, the columnar body, the plate-shaped body and the reinforcing plate provided on the four-eye plate can more effectively ensure the stability of the four-eye plate. And the connecting parts on the four-point connector can stably connect with various components on the mooring system simply and quickly.

[0010] Further, the connecting part and the components on the mooring system are in a detachable connection relationship. Further, the connecting part and the four-eye plate are movably connected, which can make the connection between the mooring system and the four-eye plate more movable and more adaptable to the impact of sea waves.

[0011] In one embodiment, holes for connecting with the connecting parts are provided at both ends of the columnar body and the plate-shaped body; there are four groups of the reinforcing plates, and they are respectively arranged in the angular directions of the columnar body and the plate-shaped body, and the planar structure of the reinforcing plate is a right triangle.

[0012] In one embodiment, the thickness of the two end positions of the columnar body is less than the thickness of the middle position of the columnar body, and the thickness of the middle position of the columnar body is less than the transverse width of the plate-shaped body.

[0013] Such a setting can make the center of the four-eye plate more balanced, capable of bearing greater force and more balanced in force.

[0014] Further, a slope is provided at the junction of the two end positions and the middle position of the columnar body. By setting the slope, it can effectively prevent the interference between the middle convex position of the columnar body and the connecting part, resulting in wear.

[0015] In one embodiment, the four-eye plate and the connecting parts are made of metal, and the ends of the columnar body and the plate-shaped body have arcs.

[0016] A four - point connector made of metal, which is stronger in rigidity and higher in lifespan. By setting arcs at the ends of the columnar body and the plate - like body, the top of the four - eye plate is made softer, making the connection with the components of the mooring system more friendly.

[0017] A mooring system for fixing a buoy, including the above - mentioned four - point connector, and also including an anchor chain, a rope, and an anchor. The rope is divided into the front - middle part and the middle - rear part. The middle - rear part of the rope is fixedly connected to the anchor, the front - middle part of the rope is connected to one end of the anchor chain, and the other end of the anchor chain is connected to the buoy.

[0018] The anchor includes at least two groups, which are arranged in sequence at the middle - 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. The number of the middle anchors corresponds one - to - one with the number of the four - point connectors.

[0019] The four - point connector is arranged at the middle - rear part of the rope. The middle - rear part of the rope is divided into several segments by the four - point connector, and the adjacent two segments of the rope are respectively connected to the left connecting part and the right connecting part on the four - point connector. The lower connecting part of the four - point connector is connected to the middle anchor. An anchor chain is provided on the middle anchor and is connected to the lower connector of the four - point connector through the anchor chain.

[0020] By setting the middle anchor, the position of the rope can be better fixed, and then the rope can fix the buoy more firmly. And setting the middle anchor can also increase the grip and make the bottom of the rope more stable.

[0021] Since the position where the rope is fixed to the middle anchor is subject to greater wear, by setting the four - point connector, the wear of the rope can be effectively avoided, and it is also more convenient to fix the middle anchor and the buoy at the same position. While achieving the horizontal suspension state of the rope, the force on the rope can be made more uniform. In addition, the setting of the four - point connector is also convenient for increasing or shortening the length of the rope to make the rope adapt to different deep - water depth requirements.

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

[0023] Preferably, the rope between two adjacent four - point connectors is in a straight state.

[0024] In one embodiment, a float ball is connected to the upper connecting part of the four - point connector. An anchor chain is provided on the float ball and is connected to the upper connecting part of the four - point connector through the anchor chain.

[0025] Furthermore, through the middle iron anchor and the floating ball, the middle and rear parts of the rope are arranged in a quasi-linear form, which not only avoids the friction between the rope and the seabed and the resulting wear, but also makes the fixation of the middle and rear parts of the rope more stable and more resistant to the disturbance of seawater.

[0026] In one embodiment, an anchor chain is provided on the bottom iron anchor and is connected to the bottommost part of the rope through the anchor chain; the middle and rear parts of the rope are connected to the front middle part of the rope in a quasi-linear shape, close to the seabed and suspended above the seabed under the action of the anchor chain and the floating ball.

[0027] Furthermore, a four-point connector or a three-point connector can also be provided at the bottommost part of the rope as needed to make the connection between the rope and the bottom iron anchor more stable.

[0028] In one embodiment, several groups of counterweight blocks are provided in the front middle part of the rope. Anchor chains are provided on the counterweight blocks and are connected to the rope through the anchor chains, so that the front middle part of the rope is connected to the middle and rear parts of the rope in a parabolic shape.

[0029] By providing the counterweight blocks, 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 be more stably fixedly connected to 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, since the rope is connected to the iron anchor in a way that infinitely approaches the seabed, it can play a buffering role for the iron anchor, avoiding the rigid stretching between the iron anchor and the rope, resulting in the iron anchor being unstable or the rope being easily worn. On the other hand, the parabolic form of the rope makes the rope 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, and then make the connection between the anchor chain and the rope more stable and less worn; and the buoy can also be more stable, avoiding too much shaking.

[0030] Moreover, by fixing the rope in a parabolic form, compared with the traditional S-shaped way of fixing the rope, it can also shorten the required rope length under the same seawater depth, thereby saving costs.

[0031] In one embodiment, the front middle part of the rope is divided into several sections, and a three-point connector is provided between adjacent sections of the rope. The three vertices of the three-point connector are respectively provided with a first connection part, a second connection part and a third connection part. The first connection part and the second connection part are arranged oppositely for connecting adjacent sections of the rope; the third connection part is arranged downward for connecting the anchor chain on the counterweight block and then connecting to the counterweight block.

[0032] By providing the three-point connector, the wear of the counterweight block on the rope can be effectively avoided.

[0033] In one embodiment, the counterweight blocks include at least two groups, and the closer the anchor chain on the counterweight block is to the middle and rear part of the rope, the shorter its length is, and the farther the anchor chain is from the middle and rear part of the rope, the longer its length is.

[0034] Through the setting of the anchor chain on the counterweight block, the counterweight block is connected to the rope, and it is ensured that the front and middle parts of the rope are arranged in a parabolic shape. Through the change of the length of the anchor chain, it is also beneficial to adapt to the changes of the sea waves, so that the rope is more stable.

[0035] In one embodiment, the middle iron anchors include at least two groups, and each group of middle iron anchors is connected to the rope through the four-point connector.

[0036] By setting two groups of counterweight blocks and middle iron anchors, it is beneficial to fix the rope more stably, so that the buoy has stronger tensile resistance and anti-displacement ability.

[0037] Further, the iron anchor of this technical solution is a Hall anchor. Using the Hall anchor to grip the ground can better adhere to the ground and form a strong horizontal gripping force.

[0038] Further, the rope of this technical solution can be a polypropylene rope, a nylon rope or a high-molecular high-strength rope. Among them, the length of the rope is determined according to the water depth, the maximum wave height, the maximum tidal range, the spring tide, and the rope length required for hoisting.

[0039] Further, the anchor chain of this technical solution can be a steel anchor chain, which can effectively fix the buoy and can effectively resist the mechanical wear caused by the sea water fluctuation. Specifically, the anchor chain of this technical solution is a studded steel anchor chain, and the length of the studded steel anchor chain can be adjusted according to needs to better meet the user's requirements.

[0040] In one embodiment, a float ball can be selectively connected to the top of the rope. When the connection between the anchor chain and the rope is disconnected, the top of the rope is connected to the float ball, and the float ball floats on the sea surface after being connected to the rope.

[0041] In this technical solution, the setting of the float ball is beneficial for people to quickly find the positioning point of the buoy during 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 float in the sea, if it needs to be used again, it still needs to be searched within a certain range. By fixing a float ball on the rope and making the float ball float on the sea surface, the position of the float ball is the position for fixing the buoy again, so that the position for fixing the buoy can be quickly found, which better meets the user's needs.

[0042] Further, a fastening device is provided at the top of the rope for quickly fastening and fixing with the anchor chain or the float ball. Further, the float ball can also be provided with an anchor chain or other connecting parts for easy connection and fixing with the rope.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0044] By providing a four-point connector, the present invention can effectively ensure the connection strength between the rope and the middle iron anchor / float, and avoid wear of the rope at the connection position with the middle iron anchor / float due to multiple impacts of sea waves, thereby effectively extending the service life of the rope.

[0045] By providing a counterweight, a middle iron anchor and a float, the present invention restricts the shape of the rope in the sea, ensuring that the front and middle parts of the rope are arranged in a parabolic shape, while the middle and rear parts of the rope are arranged in a shape similar to a straight line and are close to and suspended above the seabed. This can make the rope more adaptable to sea waves and grip the ground more firmly.

[0046] By providing multiple groups of iron anchors, the present invention can effectively ensure that the mooring system has a strong horizontal grip.

[0047] The mooring system of the present invention can be widely applied to various fields such as buoy fixing, wind power devices, and marine ranch equipment-type aquaculture, and has strong stability and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The drawings of the present invention are only for illustrative purposes and should not be construed as a limitation of the present invention. For better illustration of the following embodiments, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0054] Embodiment 1

[0055] As Figure 1 and Figure 2As shown in the figure, this embodiment discloses a four-point connector, which is arranged on a mooring system and includes: a four-eye plate 710 and connecting parts 720 arranged in the four vertex directions of the four-eye plate 710, namely a left connecting part and a right connecting part arranged in the horizontal direction, and an upper connecting part and a lower connecting part arranged in the vertical direction. Among them, the left and right connecting parts in the horizontal direction are generally connected to two adjacent ropes on the mooring system, and the upper and lower connecting parts arranged in the vertical direction can be connected to other components on the mooring system as needed.

[0056] Specifically, the four-eye plate 710 includes a columnar body 711 arranged horizontally and a plate-shaped body 712 arranged vertically, and a reinforcing plate 713 is provided between the columnar body 711 and the plate-shaped body 712. The reinforcing plate 713 includes a total of four groups and is arranged in the included angle direction of the columnar body 711 and the plate-shaped body 712 to play a role in strengthening and fastening; in addition, the reinforcing plate 713 is respectively perpendicular to the columnar body 711 and the plate-shaped body 712, and the plane structure of the reinforcing plate 713 is a right triangle. The columnar body 711, the plate-shaped body 712 and the reinforcing plate 713 are integrally formed; holes 730 are respectively provided at both end positions of the columnar body 711 and the plate-shaped body 712 for connecting the four connecting parts 720 on the four-eye plate 710. Such a structure of the four-eye plate 710 has a more balanced force and a more stable connection with the four connecting parts, and is not easy to tip over.

[0057] Furthermore, the connecting part 720 and the components on the mooring system are in a detachable connection relationship, and the connecting part 720 and the four-eye plate 710 are in a movable connection, so that the connection between the mooring system and the four-eye plate 710 has better mobility and can better adapt to the impact of sea waves.

[0058] Preferably, the thickness of both end positions of the columnar body 711 is less than the thickness of the middle position of the columnar body 711, and the thickness of the middle position of the columnar body 711 is less than the horizontal width of the plate-shaped body 712. Such a setting can make the center of the four-eye plate 710 more balanced, can bear greater force, and has a more balanced force.

[0059] Preferably, the four-eye plate 710 and the connecting part 720 are made of metal, and the ends of the columnar body 711 and the plate-shaped body 712 have arcs. The four-point connector 700 made of metal has stronger rigidity and higher service life. By setting arcs at the ends of the columnar body 711 and the plate-shaped body 712, the top of the four-eye plate 710 can be made softer and the connection with the components of the mooring system is more friendly.

[0060] Embodiment 2

[0061] As Figure 1 、 Figure 3 and Figure 4As shown in the figure, this embodiment discloses a mooring system for fixing a buoy 400, which includes an anchor chain 100, a rope 200, and an iron anchor. It also includes the four-point connector 700 of Embodiment 1. Among them, the rope 200 is divided into the front-middle part and the 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 chain 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 as to facilitate pulling the rope 200 by the iron anchor and then fixing the buoy 400. When it is necessary to tow the buoy 400 back to the shore, the connection between the top of the rope 200 and the anchor chain 100 can be released, and then the buoy 400 can be released.

[0062] Furthermore, in order to more firmly fix the rope 200, resist the impact of sea waves, and provide greater gripping force, this technical solution also sets a bottom iron anchor 310 in the middle-rear part of the rope 200 and a middle iron anchor 320 between the bottom iron anchor 310 and the counterweight 500. Specifically, in this embodiment, the middle iron anchor 320 includes i groups, and the i groups of counterweights 500 are arranged in sequence from the front-middle part to the middle-rear part of the rope 200, and are named the first middle iron anchor, the second middle iron anchor... the i-th middle iron anchor in turn.

[0063] Furthermore, in order to prevent the middle-rear part of the rope 200 from contacting and rubbing against the seabed, which may affect the service performance and lifespan, this technical solution also sets several groups of floats 600 on the middle-rear part of the rope 200, so that the middle-rear part of the rope 200 is in a quasi-straight shape and is connected to the front-middle part of the connecting rope 200 in a form close to and suspended above the seabed.

[0064] By setting the floats 600, the bottom end of the rope 200 can also be lifted to avoid the friction between the lowest end of the rope 200 and the seabed. Specifically, the number of floats corresponds one-to-one with the number of middle iron anchors.

[0065] Furthermore, the middle-rear part of the rope 200 is divided into several small segments, and adjacent small segments of the rope are connected by the four-point connector 700. Specifically, the four-point connector 700 is set at the connection position between the rope 200 and the middle iron anchor 320. Further, the left connection part and the right connection part of the four-point connector 700 in the horizontal direction are respectively connected to adjacent small segments of the rope 200; and the upper connection part of the four-point connector 700 is connected to the float 600 to fix the position of the float 600; the lower connection part is connected to the middle iron anchor 320 to fix the middle iron anchor 320. Specifically, both the float 600 and the middle iron anchor 320 are provided with anchor chains 100, and are respectively connected to the upper connection part and the lower connection part of the four-point connector through the anchor chains 100.

[0066] Among them, by setting the floating ball 600 on the four-point connector 700, the floating ball 600 can be better fixed, and the friction of the floating ball 600 against the rope 200 can be avoided. In addition, by setting the floating ball 600 above the middle anchor 320, the rope 200 can be better pulled up, avoiding the friction between the rope 200 and the seabed and affecting the service life. By setting the four-point connector 700, the floating ball 600 and the middle anchor 320 can be effectively fixed, and the friction against the rope 200 can be effectively avoided, improving the service life of the rope 200. Preferably, the connecting parts of the four-point connector 700 are detachably connected to the rope 200, the floating ball 600 and the middle anchor 320 respectively for easy replacement.

[0067] Further, to make the force on the rope 200 between adjacent anchors more uniform, the four-point connectors 700 are evenly distributed on the rope 200. That is, the lengths of the ropes 200 between adjacent four-point connectors 700 are the same.

[0068] Further, to better fix the buoy 400, two groups of middle anchors 320 are provided in the middle and rear parts of the rope 200, and two groups of four-point connectors 700 and floating balls 600 are correspondingly provided on the two groups of middle anchors 320.

[0069] Specifically, the length of the anchor chain on the floating ball 600 is 3 - 5 meters, and the length of the anchor chain on the middle anchor 320 is 4 - 6 meters.

[0070] As Figure 3 and Figure 5 shown, further, n groups of counterweight blocks 500 are also provided in the front and middle parts of the rope 200 in this embodiment. Specifically, the n groups of counterweight blocks 500 are sequentially fixed on the rope 200 between the anchor chain 100 and the anchor to weight the rope 200, so that the front and middle parts of the rope 200 are connected in a parabolic form between the anchor chain 100 and the anchor. Among them, the n groups of counterweight blocks 500 are arranged in the order from the top of the rope 200 to the middle and rear parts of the rope 200, and are sequentially named the first counterweight block, the second counterweight block... the nth counterweight block.

[0071] Specifically, the front-middle part of the rope 200 is divided into several segments. A three-point connector 900 is provided between adjacent segments of the rope 200 and they are connected through the three-point connector 900. Further, at least three connection positions are provided on the three-point connector 900, 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 caused by the counterweight 500 can be effectively avoided. Among them, anchor chains 100 are provided on the counterweights 500, and the counterweights 500 are detachably connected to the third connection position of the three-point connector 900 through the anchor chains 100. Further, the length of the anchor chain 100 on the first counterweight is longer than the length of the anchor chain 100 on the second counterweight. Such a setting can better ensure the parabolic form of the front half of the rope 200, and can also make the setting of the rope 200 closer to the wave form of the sea wave, so that the rope 200 is more stable and the buoy 400 is more firm.

[0072] Further, an anchor chain 100 is provided on the bottom iron anchor 310, and the bottom iron anchor is connected to the rope 200 through the anchor chain 100. Further, the bottom iron anchor can also be connected to the anchor chain 100 by connecting a three-point connector or a four-point connector.

[0073] Preferably, the anchor chain 100 is a studded steel anchor chain, and its length can be set as required. The property of steel can also play a better role in fixing and buffering.

[0074] Further, the rope 200 in this embodiment is a polypropylene rope, a nylon rope or a high-molecular high-strength rope. Among them, the length of the rope 200 is determined according to the water depth, the maximum wave height, the maximum tidal range, the spring tide, and the rope length required for hoisting.

[0075] Further, the anchor chain 100 in this embodiment is a studded steel anchor chain, and the length of the studded steel anchor chain can be adjusted as required, and it can also effectively resist mechanical wear caused by the fluctuation of seawater.

[0076] Further, the number and weight of the counterweights 500 can be set according to the undulation of the waves to ensure that the rope 200 is connected in a parabolic form between the iron anchor and the anchor chain 100.

[0077] Specifically, in actual operation, when disconnecting the connection between the anchor chain 100 and the rope 200, a floating ball can be fixed at the top of the rope 200. After the floating ball is connected to the rope 200, it floats on the sea surface. When it is necessary to fix the buoy 400 again, the positioning point of the buoy 400 can be quickly found through the floating ball.

[0078] Further, a fastening device can be provided at the top of the rope 200 for quickly fastening and fixing with the anchor chain 100 or the floating ball.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solutions of the present invention, rather than limitations on the specific implementation manners of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the claims of the present invention shall be included within the protection scope of the claims of the present invention.
