Description

Technical Field

[0001] The present invention relates to the technical field of mooring systems, and in particular to a flywheel energy storage type dock ship auxiliary mooring system and a control method. Background Art

[0002] Today, the water transportation industry is developing rapidly. As the size of ships increases, the traffic volume increases, the docks become busier, and the problem of ship berthing becomes increasingly prominent. Common severe weather conditions such as waves and strong winds, as well as the ship waves of passing ships, can lead to unsafe loading and unloading problems. As ports develop in the direction of "open, deep water, and large tonnage", the conditions for ship berthing are becoming more and more challenging. Even in good weather conditions, the changes in the ship's draft or tidal water level also require dynamic adjustment of the cables, which increases the possibility of accidents caused by human errors. Once the mooring configuration is improper or the operation is wrong, it may cause the ship's motion response to be too large, and even very serious accidents such as cable breakage, ship collision, and casualties may occur.

[0003] In the prior art, the shore-based mooring adjustment system is generally driven by a hydraulic system to perform reciprocating adjustment, but its response speed is slow, and the energy consumption is very large. The hydraulic oil pollution is also easy to cause great damage to the environment. At the same time, it occupies a large area on the dock. Summary of the invention

[0011] According to the above-mentioned flywheel energy storage dock ship auxiliary mooring system, the reverse gear has a forward gear and a reverse gear. When the flywheel is in an energy storage state, the reverse gear is in a forward gear state, and when the flywheel is in an energy release state, the reverse gear is in a reverse gear state.

[0016] S1: Mooring pre-tightening: After connecting the ship and the capstan with the loose mooring cable, the management module transmits the preset tension range information of the mooring cable to the electronic control module. The electronic control module controls the motor through the inverter to drive the flywheel to rotate, and drives the capstan to reverse the mooring cable through the flywheel until the tension of the mooring cable is adjusted to within the preset tension range;

[0017] S2: Real-time adjustment: Under the influence of wind and waves, the ship has a tendency to move away from the shore and towards the shore. The electronic control module obtains the real-time tension information of the mooring cable according to the real-time movement trend of the ship;

[0018] When the ship has a tendency to move offshore, if the tension of the mooring cable is greater than the maximum tension value of the preset tension range, the electronic control module controls the flywheel to store energy, at which time the capstan rotates forward and releases the mooring cable until the tension of the mooring cable is adjusted to the preset tension range;

[0019] When the ship has a tendency to move toward the shore, if the tension of the mooring cable is less than the minimum tension value of the preset tension range, the electronic control module controls the flywheel to release energy. At this time, the capstan reverses and winds the mooring cable until the tension of the mooring cable is adjusted to the preset tension range.

[0020] According to the control method of the flywheel energy storage type dock ship auxiliary mooring system described above, in step S1, while the electronic control module controls the motor to move, the electronic control module controls the continuously variable transmission to be in the lowest gear, the reverse gear to be in the reverse gear, and controls the brake to be opened, and the first clutch and the second clutch to be closed;

[0021] When the tension of the mooring cable is adjusted to within a preset tension range, the electronic control module controls the brake to close, and the first clutch and the second clutch are disconnected at the same time.

[0022] According to the control method of the flywheel energy storage dock ship auxiliary mooring system described above, in step S2, when the tension of the mooring cable is greater than the maximum tension value of the preset tension range, the electronic control module first controls the brake to open, the reverse gear to return to the forward gear, and gradually adjusts the reduction ratio of the continuously variable transmission. When the speed of the high-speed shaft of the continuously variable transmission is consistent with the speed of the flywheel, the electronic control module can control the first clutch to close;

[0023] When the tension of the mooring cable is adjusted to within a preset tension range, the electronic control module controls the brake to close and the first clutch to open.

[0024] According to the control method of the flywheel energy storage dock ship auxiliary mooring system described above, in step S2, when the tension of the mooring cable is less than the minimum tension value of the preset tension range, the electronic control module controls the brake to open, the reverse gear to switch to reverse gear, and the first clutch to close, and the flywheel drives the winch to wind the mooring cable through the reverse gear, wherein:

[0025] The electronic control module can control the continuously variable transmission to adjust the transmission ratio to control the speed at which the winch winds up the cable.

[0026] The present invention has the following beneficial effects:

[0027] 1. After mooring, if the ship moves offshore, the mooring cable will be straightened. Once the tension of the mooring cable is too large, the electronic control module can control the flywheel to switch to the energy storage state. At this time, the capstan starts to rotate forward and releases the mooring cable to reduce the tension of the mooring cable. At the same time, it can drive the flywheel to rotate. The motion energy can drive the flywheel to rotate and is stored in the flywheel in the form of rotational potential energy. When the tension of the mooring cable is too small, the electronic control module controls the flywheel to switch to the energy release state, and drives the capstan to reverse through the capacity stored in the flywheel, and can wind the mooring cable to increase the tension of the mooring cable to meet the mooring requirements. Therefore, most of the reciprocating motion is provided to the flywheel by the movement of the ship, which consumes very little energy and is more environmentally friendly.

[0028] 2. The management module can provide the electric control module with the preset tension range information of the mooring cable based on various factors, and obtain the mooring cable tension information through the electric control module to determine whether it is within the preset tension range, and immediately realize the control of other modules. It has a fast response speed and can improve the control accuracy;

[0029] 3. A continuously variable transmission is provided in the transmission module, through which the transmission ratio can be adjusted to achieve the maximum energy storage of the flywheel;

[0030] 4. A quick release device is provided on the capstan, which can completely release the mooring cable in an emergency situation to avoid locking the ship and ensure its safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0045] like Figure 1-3As shown, a flywheel energy storage dock ship auxiliary mooring system is arranged on a dock 8 and is used to connect the ship 7 and the dock 8 to achieve the mooring of the ship 7. It includes an energy storage module, a transmission module, a winch module, an electric control module 4, an energy supply module and a management module 6, wherein the winch module includes a capstan 31 and a mooring cable 32, one end of the mooring cable 32 is connected to the capstan 31, and the other end can be connected to the ship 7 to moor the ship 7, the energy storage module includes a flywheel 11, and the flywheel 11 has an energy storage state and an energy release state, the management system is used to determine the preset tension range of the mooring cable 32, and transmit the preset tension range information of the mooring cable 32 to the electric control module 4, and the electric When the control module 4 obtains the tension information of the mooring cable 32, it determines whether it exceeds the preset tension range, and switches the energy storage state and the energy release state of the flywheel 11 through the transmission module. When the tension of the mooring cable 32 is too large, that is, when the ship 7 has a tendency to move offshore, the flywheel 11 can absorb the ability of the ship 7 to release the mooring cable 32 due to the offshore movement. When the tension of the mooring cable 32 is too small, the flywheel 11 releases energy to drive the capstan 31 to wind the mooring cable 32, so as to tighten the mooring cable 32. The tension of the mooring cable 32 can be adjusted in real time, which is more in line with the mooring requirements of the ship 7. At the same time, the flywheel 11 is used to store and release energy, which can greatly save energy consumption and is more environmentally friendly.

[0046] In this embodiment, a mooring post is provided on the pier 8, and the flywheel 11 energy storage mooring auxiliary system is fixed on one side of the mooring post.

[0047] Specifically, the transmission module includes a reducer 21, a reverse gear 22 and a continuously variable transmission 23 connected in series in sequence, and the capstan 31 is rotatably fixed on the dock 8. The low-speed shaft of the reducer 21 is connected to the transmission shaft of the capstan 31 through a flexible coupling 24, and the high-speed shaft of the reducer 21 is connected to the low-speed shaft of the reverse gear 22, and a brake 25 is provided on the high-speed shaft of the reducer 21, and the high-speed shaft of the reverse gear 22 is connected to the low-speed shaft of the continuously variable transmission 23, and the high-speed shaft of the continuously variable transmission 23 is connected to the flywheel 11, wherein the reverse gear 22 is provided with a forward gear and a reverse gear. In a normal mooring state, that is, when the tension of the mooring cable 32 is within a normal range, the reducer 21, the reverse gear 22 and the continuously variable transmission 23 are all not working, and at this time the brake 25 is closed, and the flywheel 11 and the capstan 31 are not moving and remain in a stationary state.

[0048] Among them, the reducer 21 plays a role in changing the rotation speed and torque. From the side of the capstan 31 to the side of the flywheel 11, it can increase the rotation speed and reduce the output torque, accelerate the rotation of the flywheel 11, and from the opposite direction, reduce the rotation speed of the capstan 31, but increase the torque of the capstan 31; the low-speed shaft of the reducer 21 is connected to the transmission shaft of the capstan 31 through the flexible coupling 24, and the flexible coupling 24 can be used to absorb the impact of the tension change of the mooring cable 32 on the transmission module, which can reduce the overall vibration and noise; the continuously variable transmission 23 is used to adjust the transmission ratio so that the flywheel 11 can reach the maximum energy storage value; the reverse gear 22 has a forward gear and a reverse gear, which is used to switch whether the direction between its high-speed shaft and the low-speed shaft is consistent.

[0049] If there are wind and waves, the ship 7 may have a tendency to move away from the shore or to the shore. If the ship 7 has a tendency to move away from the shore, the tension of the mooring cable 32 will continue to increase. Once the tension exceeds the preset value, there may be a risk of the mooring cable 32 breaking. At this time, the electronic control module 4 controls the brake 25 to open, and the winch 31 releases the mooring cable 32. In this process, the electronic control module 4 controls the first clutch 12 to close, the reverse gear 22 to switch to the forward gear, and the flywheel 11 is in the forward loading state. At this time, the reverse gear 22 is in the forward gear. The high-speed shaft and the low-speed shaft have the same direction of rotation; if the ship 7 approaches, the tension of the mooring cable 32 will drop rapidly, and the mooring cable 32 cannot assist the mooring of the ship 7. Therefore, when the tension of the mooring cable 32 is too low, the electronic control module 4 controls the brake 25 to open and the first clutch 12 to close. At this time, the reverse gear 22 is switched to the reverse gear, and the flywheel 11 is in an energy release state, which drives the capstan 31 to reel in the mooring cable 32, thereby increasing the tension of the mooring cable 32. Therefore, the flywheel 11 can provide tension for the mooring cable 32.

[0050] The electric control module 4 uses a plurality of sensors to detect the tension of the mooring cable 32 .

[0051] Furthermore, in order to ensure that the mooring cable 32 plays a better mooring role and to improve the mooring safety performance, the winch module also includes a cable guide 33 and a quick release device 34. The cable guide 33 is located on one side of the capstan 31, and one end of the mooring cable 32 passes through the cable guide 33 and is connected to the ship 7, that is, the direction of the mooring cable 32 can be changed through the cable guide 33, so as to facilitate the application of a force in a specific direction to the ship 7. At the same time, the quick release device 34 is fixed on the capstan 31, and one end of the mooring cable 32 close to the capstan 31 is connected to the quick release device 34. When the tension of the mooring cable 32 is too large and exceeds the limit or when the ship 7 needs to be started urgently, the mooring cable 32 can be disconnected from the capstan 31 through the quick release device 34.

[0052] In order to ensure that the flywheel 11 has enough energy to provide the energy required for mooring, an energy supply module is also included. The energy supply module includes an electric motor 51 and an inverter 52. The electric motor 51 is connected to the flywheel 11 through the second clutch 13 and can drive the flywheel 11 to rotate. The electronic control module 4 can adjust the output speed of the electric motor 51 through the inverter 52. The output speed of the electric motor 51 is continuously adjusted to achieve the adjustment of the speed of the flywheel 11, and the energy provided to the flywheel 11 can be limited within a preset time.

[0053] like Figure 1-4 As shown, a control method of a flywheel energy storage type dock ship auxiliary mooring system is shown, wherein the flywheel energy storage type dock ship auxiliary mooring system is as described above, the flywheel energy storage type dock ship auxiliary mooring system is fixed on the dock 8, and the flywheel energy storage type dock ship auxiliary mooring system includes an energy storage module, a transmission module, a winch module, an electronic control module 4, an energy supply module and a management module 6, the winch module includes a capstan 31, a quick release device 34 and a mooring cable 32, one end of the mooring cable 32 is connected to the capstan 31 through the quick release device 34, the transmission module includes a reducer 21, a reverse gear 22 and a continuously variable transmission 23 connected in series in sequence, the low-speed shaft of the reducer 21 is connected to the capstan 31, and a brake 25 is provided on the high-speed shaft of the reducer 21, the energy storage module includes a flywheel 11, the flywheel 11 is connected to the continuously variable transmission 23 through a first clutch 12, the energy supply module includes a motor 51 and a frequency converter 52, and the motor 51 is connected to the flywheel 11 through a second clutch 13, and the control method includes the steps of:

[0054] S1: Mooring pre-tightening: After the vessel 7 and the capstan 31 are connected by the loose mooring cable 32, the management module 6 transmits the preset tension range information of the mooring cable 32 to the electric control module 4, and the electric control module 4 controls the motor 51 through the inverter 52 to drive the flywheel 11 to rotate, and drives the capstan 31 to reverse the mooring cable 32 through the flywheel 11, until the tension of the mooring cable 32 is adjusted to within the preset tension range, that is, when the flywheel 11 has not yet stored energy, the motor 51 supplies energy to the flywheel 11 of the electric control module 4, so that it can drive the capstan 31 to reverse the tension to tighten the mooring cable 32. The mooring cable 32, during this process, the electronic control module 4 needs to control the brake 25 to open, the first clutch 12 and the second clutch 13 to close, and the continuously variable transmission 23 to be in the lowest gear, and the reverse gear 22 to be in the reverse gear, so as to achieve the purpose of driving the winch 31 to reverse by the flywheel 11, and when the tension of the mooring cable 32 reaches within the preset tension range, the electronic control module 4 controls the brake 25 to close, and the first clutch 12 and the second clutch 13 to be disconnected at the same time. In this embodiment, the electronic control module 4 detects the tension of the mooring cable 32 through multiple sensors.

[0055] S2: Real-time adjustment: Under the influence of wind and waves or other external factors, the ship 7 will be in a state of motion, which can be roughly divided into two situations, that is, the ship 7 has an offshore motion trend and a shore motion trend. At this time, the electronic control module 4 obtains the real-time tension information of the mooring cable 32 according to the real-time motion trend of the ship 7, and controls according to the two situations:

[0056] When the ship 7 has a tendency to move offshore, the ship 7 will drive the mooring cable 32 to move toward the side away from the dock 8. At this time, the tension of the mooring cable 32 continues to increase. Once the tension of the mooring cable 32 increases to a maximum value greater than the preset tension range, the electronic control module 4 controls the winch 31 to rotate forward and release the mooring cable 32. In this process, the electronic control module 4 can control the brake 25 to open and the reverse gear 22 to return to the forward gear. The electronic control module 4 gradually adjusts the reduction ratio of the continuously variable transmission 23. When the speed of the high-speed shaft of the continuously variable transmission 23 is consistent with the speed of the flywheel 11, the electronic control module 4 can control the first clutch 12 to close. In this process, the winch 31 drives the flywheel 11 to rotate through the reducer 21, the reverse gear 22 and the continuously variable transmission 23, thereby realizing the energy storage of the flywheel 11. Until the tension of the mooring cable 32 is adjusted to the preset tension range, the electronic control module 4 controls the brake 25 to close and the first clutch 12 to disconnect. At this time, the winch 31 will also gradually stop moving.

[0057] Of course, in this case, in addition to braking with the brake 25, another way is to change the gear position of the reverse gear 22 so that the winch 31 cannot release the mooring cable 32, which can also achieve the purpose.

[0058] When the ship 7 has a tendency to move toward the shore, the mooring cable 32 moves with the ship 7 toward the side close to the pier 8, and its tension is gradually reduced. Once the tension of the mooring cable 32 is less than the minimum value of the preset tension range, the flywheel 11 starts to release energy. At this time, the electronic control module 4 controls the flywheel 11 to release energy, and drives the winch 31 to flip and wind the mooring cable 32 until the tension of the mooring cable 32 is adjusted to within the preset tension range. In this process, the electronic control module 4 controls the brake 25 to open, the reverse gear 22 to switch to reverse gear, and the first clutch 12 to close. The flywheel 11 drives the winch 31 to wind the mooring cable 32 through the reverse gear 22. The electronic control module 4 can control the continuously variable transmission 23 to adjust its transmission ratio to control the speed at which the winch 31 winds the mooring cable 32.

[0059] Of course, the above control method is only used when the energy stored in the flywheel 11 is greater than or equal to the energy required to wind the cable 32 to a preset tension value range. When the energy stored in the flywheel 11 is too low, the electronic control module 4 controls the motor 51 to function for the flywheel 11 to meet its requirements.

[0060] In this embodiment, the motor 51 may be connected to the shore power of the dock 8 to meet the power demand of the motor 51 .
