Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mooring systems, and particularly relates to a new heavy block and pulley energy storage mooring system and a marine floating platform. BACKGROUND

[0002] The fixed mooring system design of a marine floating platform structure as a marine structure bearing carrier is particularly crucial. The mooring system is a system for fixing a ship, a floating platform or other marine structure in a water body, usually composed of anchors, mooring lines, connectors, anchor chains and floating platform structures, to prevent the marine structure facility from drifting due to tides, wind, waves or ocean currents. The mooring system ensures the stability and position control of these structures in the water through anchoring, ropes or chains, and plays a crucial role in scenarios such as ship berthing, marine platform operation, floating facility maintenance, etc.

[0003] Traditional mooring system designs vary according to different platform carriers, including catenary mooring systems, tension mooring systems, single-point mooring systems and multi-point mooring systems. However, due to various objective factors such as the large size and heavy weight of the designed platform, the existing mooring system has a large number of designed mooring chains, and the single mooring chain has a large carrying capacity, which requires strict material selection, resulting in expensive mooring system design and construction. In addition, the existing mooring system usually only considers how to stably constrain the overall floating platform structure in the design, without considering the energy-saving effect at the same time, resulting in low energy utilization efficiency.

[0028] Please refer to Figures 1 to 4 The embodiment of the present application provides a new heavy block and pulley energy storage mooring system, which comprises a floating body 10, an energy conversion assembly 20 arranged on the floating body 10, a counterweight assembly 30 located below the floating body 10 and a mooring chain 40 connected with the counterweight assembly 30, one end of the mooring chain 40 is anchored to the bottom of water, the other end of the mooring chain 40 is connected with the counterweight assembly 30, the energy conversion assembly 20 comprises a rotating shaft 21 arranged in rotation, a traction rope 22 wound on the rotating shaft 21 and a generator 23 in transmission connection with the rotating shaft 21, one end of the traction rope 22 is connected with the counterweight assembly 30, the counterweight assembly 30 keeps the traction rope 22 in tension through its own gravity, the rotating shaft 21 has a first state of keeping still and a second state of being rotatable, when the rotating shaft 21 is in the first state, the rotating shaft 21 fixes the traction rope 22, when the rotating shaft 21 is in the second state, the counterweight assembly 30 falls under the action of gravity to drive the rotating shaft 21 to rotate, and the generator 23 converts the rotational kinetic energy of the rotating shaft 21 into electrical energy.

[0029] Understandably, the floating body 10 is floated on the water surface under the action of buoyancy, the counterweight assembly 30 has a certain weight, so the counterweight assembly 30 sinks into water under the action of its own gravity, and the position of the counterweight assembly 30 in water can be raised and lowered. One end of the mooring chain 40 is anchored to the bottom of water, specifically, one end of the mooring chain 40 can be connected with an anchoring structure 60, so that one end of the mooring chain 40 can be anchored to the bottom of water through the anchoring structure 60.

[0030] It should be noted that in the initial state without power generation, the rotating shaft 21 is in the first state, at which the rotating shaft 21 is locked and cannot rotate, the traction rope 22 is wound on the rotating shaft 21, and the height of the counterweight assembly 30 will not change, at which the counterweight assembly 30 is at a preset height relative to the water bottom, and when power generation starts, the rotating shaft 21 is switched from the first state to the second state, the locking state of the rotating shaft 21 is released so that the rotating shaft 21 can rotate, at which the counterweight assembly 30 falls under the action of gravity, the traction rope 22 is released, and the friction between the traction rope 22 and the rotating shaft 21 drives the rotating shaft 21 to rotate, and the generator 23 converts the rotational kinetic energy of the rotating shaft 21 into electrical energy, so as to realize the conversion of the gravitational potential energy of the counterweight assembly 30 into electrical energy.

[0031] The novel heavy block and pulley energy storage mooring system provided by the application can utilize the gravity of the counterweight assembly 30 to offset the buoyancy of the ocean floating platform in the ocean, effectively reduce the constraint load of the design of the ocean floating platform, further reasonably reduce the number of mooring chains 40 in the mooring system and the design use load size of each mooring chain 40, and due to the reduction of the design number and design strength of the mooring chain 40, the design cost is significantly reduced, the overall cost of the entire ocean floating platform is greatly reduced, and the cost is effectively reduced. In addition, the counterweight assembly 30 also has the function of a damper, which can consume the force received by the ocean floating platform when the entire ocean floating platform is affected by extreme wind and wave load, thereby ensuring the safety and stability of the structure above the sea level. Furthermore, by arranging the energy conversion assembly 20, when the counterweight assembly 30 falls under the action of gravity, the traction rope 22 drives the rotating shaft 21 to rotate, and the generator 23 converts the rotational kinetic energy of the rotating shaft 21 into electrical energy, thereby realizing the conversion of the gravitational potential energy of the counterweight assembly 30 into electrical energy, providing additional energy for the overall stability of the mooring system, and the energy conversion efficiency is high, pollution-free, which is conducive to improving energy utilization rate and environmental benefits.

[0032] In some embodiments, as shown in Figure 1 The counterweight assembly 30 includes a pulley 31 and a heavy block 32, the pulley 31 is connected to the traction rope 22, the mooring chain 40 is arranged around the pulley 31, one end of the mooring chain 40 is anchored to the water bottom, and the other end of the mooring chain 40 is connected to the heavy block 32. By arranging the pulley 31, when the floating body 10 is displaced under the action of external force, the mooring chain 40 is pulled under the action of gravity of the heavy block 32, and the pulled mooring chain 40 can change the direction of force through the pulley 31. By the pulley 31, the tension of the mooring chain 40 remains stable, and the sudden large tension of the mooring chain 40 when the mooring system is subjected to extreme wind and waves is avoided.

[0033] In some embodiments, as shown in Figure 3As shown, the energy conversion assembly 20 further comprises a bracket 24 and a transmission member 25, the bracket 24 is connected to the floating body 10, the rotating shaft 21 is rotatably connected to the bracket 24, and the transmission member 25 connects the rotating shaft 21 and the rotor of the generator 23 to make the rotating shaft 21 and the rotor of the generator 23 rotate synchronously, thereby realizing power generation. It should be noted that the rotor of the generator 23 is usually a rotating magnet or a current-carrying conductor, which together with the stator (fixed part) constitutes the basic structure of the generator 23. When the rotor rotates in the stator, the magnetic field generated by the rotor also rotates together, causing the magnetic flux in the stator winding to change. According to the law of electromagnetic induction, when the magnetic flux in the closed circuit changes, an induced electromotive force will be generated in the circuit. If the stator winding is a closed loop, an induced current will be generated under the action of the induced electromotive force, thereby realizing the generation of electric energy. By connecting the rotating shaft 21 and the rotor of the generator 23 through the transmission member 25, the rotating shaft 21 and the rotor of the generator 23 are made to rotate synchronously, which is simple in structure and high in transmission efficiency, and is conducive to improving the power generation efficiency.

[0034] In a specific embodiment, the rotating shaft 21 and the bracket 24 can constitute a winch, which is compact in structure, small in size, light in weight, easy to move and install between different positions, and simple to operate, and the use method is intuitive; the winch also has high carrying capacity, can lift or pull heavy objects, and can realize precise operation and control through an intelligent control system. Of course, in other possible implementations, the rotating shaft 21 and the bracket 24 can constitute an electric capstan or the like, and the embodiments are not limited to this.

[0035] It can be understood that in order to prepare for the next power generation, the traction rope 22 can be tightened by rotating the rotating shaft 21, so as to lift the pulley 31 and the weight 32, and make the pulley 31 and the weight 32 reach a high enough height, so that the pulley 31 and the weight 32 have a large gravitational potential energy, thereby making the final generator 23 convert more electric energy.

[0036] In some embodiments, the energy conversion assembly 20 further comprises an energy storage device for storing the electric energy generated by the generator 23. By providing the energy storage device to store the electric energy, the energy storage device can flexibly allocate the electric energy according to the power generation of the generator 23 and the electricity demand, thereby realizing the optimal allocation of energy. Since the power generation of the generator 23 may not completely match the actual load demand, when the load is low, if the generator 23 continues to generate power at a high power, it will cause energy waste. The energy storage device can store excess electric energy when the load is low, and release electric energy when the load is high, so that the generator 23 can stably operate in the high-efficiency power generation interval, thereby improving the energy utilization efficiency of the entire power generation system.

[0037] Optionally, the energy storage device can be an electrochemical capacitor. The electrochemical capacitor refers to a new type of energy storage element based on high specific surface area carbon materials, metal oxides and conductive polymers and other electrode materials. In the initial stage of the movement of the counterweight assembly 30, the speed of the counterweight assembly 30 is relatively small, and the power is relatively low. At this time, the electrochemical capacitor can release the stored electric energy to meet the power generation demand. Compared with the traditional capacitor, the electrochemical capacitor has larger capacity, higher energy, wider working temperature range and extremely long service life. Of course, in other possible embodiments, the energy storage device can also be a storage battery. The storage battery has stable performance and high reliability, can be used for long-term stable operation under various environmental conditions, and provides reliable protection for the energy storage device. In addition, the storage battery can be repeatedly used, reduces the impact of discarded batteries on the environment, and can also output stable electric energy to avoid damage to equipment caused by power fluctuations.

[0038] In some embodiments, the energy conversion assembly 20 is arranged on the surface of the floating body 10 away from the counterweight assembly 30. The floating body 10 is provided with a through hole through which the traction rope 22 passes, and the traction rope 22 is connected to the counterweight assembly 30 through the through hole. By arranging the energy conversion assembly 20 on the surface of the floating body 10 away from the counterweight assembly 30, i.e., on the top surface of the floating body 10, the influence of sea waves and the like on the energy conversion assembly 20 can be reduced, thereby improving the service life of the energy conversion assembly 20.

[0039] In some embodiments, as shown in Figure 1 The bottom surface of the floating body 10 is provided with a buffer structure 50. The buffer structure 50 is arranged on the movement path of the counterweight assembly 30. The buffer structure 50 can be elastically deformed under pressure to buffer the impact of the counterweight assembly 30, thereby avoiding the collision between the pulley 31 and the bottom surface of the floating body 10. In addition, through the buffering effect, the impact of the counterweight assembly 30 can be buffered, and the service life of the counterweight assembly 30 can be improved.

[0040] In some embodiments, the buffer structure 50 is a spring. The spring is sleeved on the traction rope 22, and one end of the spring away from the counterweight assembly 30 is connected to the bottom surface of the floating body 10. When the pulley 31 moves upward and presses the spring, the spring is compressed to generate a force opposite to the pressing direction of the pulley 31, thereby buffering the impact of the pulley 31. In addition, when the weight 32 moves downward under the action of gravity, the spring pushes the counterweight assembly 30 to move downward under the action of the elastic restoring force of the spring. The counterweight assembly 30 obtains more energy and has more kinetic energy, thereby making the finally converted electric energy and stored energy more, and further improving the energy utilization rate.

[0041] In some embodiments, as shown in Figure 4As shown, multiple pulleys 31 are arranged at intervals, multiple energy conversion assemblies 20 are arranged at intervals, each pulley 31 corresponds to each energy conversion assembly 20 one by one, multiple mooring chains 40 are arranged, each mooring chain 40 is arranged around each pulley 31, and each mooring chain 40 is connected to the same weight 32. Understandably, the energy conversion assembly 20, the pulley 31 and the mooring chain 40 correspond one by one, the number of the energy conversion assembly 20, the pulley 31 and the mooring chain 40 is the same, but the number of the weight 32 is arranged as one, and each mooring chain 40 is connected to the weight 32.

[0042] By connecting multiple mooring chains 40 to the same weight 32, compared with connecting multiple mooring chains 40 to multiple weights 32 respectively and the multiple weights 32 being in a scattered state, it is equivalent to integrating multiple weights 32 arranged in a scattered state into a large weight 32, so that the overall strength of the mooring system is higher, the gravity center of the weight 32 is reduced, the stability of the mooring system is further improved, and interference or collision between multiple weights 32 arranged in a scattered state during movement can be avoided, thereby improving the safety of the mooring system. In addition, by arranging multiple mooring chains 40 to connect the same weight 32, the weight 32 can be pulled in multiple directions, so that the tension on the weight 32 is more balanced, and the weight 32 is prevented from being unbalanced and colliding with the pulley 31 or the floating body 10, thereby further improving the safety of the mooring system.

[0043] Alternatively, in the embodiment of the present application, the number of energy conversion assemblies 20, pulleys 31 and mooring chains 40 is three, and the weight 32 is pulled in three directions, thereby further improving the stability of the mooring system. Of course, in other possible embodiments, the number of energy conversion assemblies 20, pulleys 31 and mooring chains 40 can also be four, five, six or more, and the number of energy conversion assemblies 20, pulleys 31 and mooring chains 40 is not uniquely limited in the embodiment of the present application.

[0044] In some embodiments, the floating body 10 has a receiving cavity 11, and the energy conversion assembly 20 is arranged in the receiving cavity 11, that is, a protective structure is formed outside the floating body 10, and the protective structure covers the outside of the energy conversion assembly 20. The protective structure can resist the interference of wind and waves in the receiving cavity 11, and prevent the energy conversion assembly 20 from being damaged or contaminated, thereby prolonging the service life of the energy conversion assembly 20.

[0045] The present application also proposes a marine floating platform, which comprises a new type of weight-pulley energy storage mooring system. The specific structure of the new type of weight-pulley energy storage mooring system is referred to the above-mentioned embodiments. Since the marine floating platform adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0046] In summary, the new heavy block and pulley energy storage mooring system provided by the present application can use the gravity of the counterweight assembly 30 to offset the buoyancy of the offshore floating platform in the sea, effectively reducing the constraint load of the offshore floating platform design, further reasonably reducing the number of mooring chains 40 in the mooring system and the design use load of each mooring chain 40, and due to the reduction of the design number and design strength of the mooring chain 40, the design cost is significantly reduced, the overall cost of the entire offshore floating platform is greatly reduced, and the cost is effectively reduced. In addition, the counterweight assembly 30 also has the function of acting as a damper, which can consume the force received by the offshore floating platform when the offshore floating platform is affected by extreme wind and wave load, thereby ensuring the safety and stability of the structure above sea level. Moreover, by setting the energy conversion assembly 20, when the counterweight assembly 30 falls under the action of gravity, the traction rope 22 will drive the rotating shaft 21 to rotate, and the generator 23 will convert the rotating kinetic energy of the rotating shaft 21 into electrical energy, thereby realizing the conversion of the gravitational potential energy of the counterweight assembly 30 into electrical energy, providing additional energy for the overall stability of the mooring system, and the energy conversion efficiency is high, pollution-free, which is conducive to improving energy utilization and environmental benefits.
