Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy recovery, in particular to a ship kinetic energy recovery system. BACKGROUND

[0002] When a large ship encounters an emergency obstacle avoidance or enters a port, it needs to slow down or stop the ship in sailing. Large ships such as oil tankers and cargo ships have a large weight and a very large inertia. A large amount of energy is consumed to provide a counter-thrust to overcome the inertia of the ship to slow down or stop the ship. Usually, the propeller is reversed and assisted by a tugboat to slow down or stop the ship. This process consumes a large amount of additional energy, further increasing the energy consumption of the large ship and reducing the economy of the large ship. If the large inertia characteristics of the ship and the power that cannot be utilized during the slowing down or stopping process can be fully utilized, the economy of the large ship will be improved.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] The following is combined with Figure 1 The present invention describes a ship kinetic energy recovery system.

[0021] like Figure 1As shown in the embodiment of the present invention, the ship kinetic energy recovery system includes: a gravity flow generator, a kinetic energy generator, and a power generation device. The gravity flow generator forms a circulation loop with the kinetic energy generator through a pipeline, and the power generation device is connected to the kinetic energy generator. The gravity flow generator has a switchable first position and a second position. When the ship is in a sailing state, the gravity flow generator is in the first position, located inside the hull 100. When the ship is in a state of inertial navigation, the gravity flow generator is in the second position, located outside the hull 100. Seawater enters the kinetic energy generator from the gravity flow generator, driving the kinetic energy generator to move, thereby driving the power generation device to operate and generate electricity.

[0022] Specifically, during normal navigation, the gravity flow generator is in its first position, located within the hull (100), to reduce drag. When the ship docks, due to its greater inertia, it will continue to travel a certain distance even after the propulsion system stops. In this case, the gravity flow generator extends outside the hull (100), resuming its second position. Submerged in seawater, the gravity flow generator operates in the opposite direction to the ship's direction of travel. Seawater flows into the generator and then along pipes into the kinetic energy generator, driving it to move. This kinetic energy generator, in turn, drives the power generation device, producing electricity. This electricity can be used by the ship's electrical equipment to improve its economic efficiency.

[0023] The ship kinetic energy recovery system provided in this embodiment of the invention, by setting up a gravity flow generator, a kinetic energy generator, and a power generation device, can utilize the ship's inertia to allow seawater to flow into the gravity flow generator and the kinetic energy generator when the ship is at rest, thereby driving the kinetic energy generator to move, so that the power generation device moves to generate electricity to supply the ship's electrical equipment, thereby reducing the ship's energy consumption and improving the economy of large ships.

[0024] like Figure 1 As shown, in an embodiment of the present invention, the gravity flow generating device includes: an inlet structure 11, an outlet structure 12, and a drive mechanism 13. The inlet structure 11 is connected to a kinetic energy generating device via a pipeline, and the kinetic energy generating device is connected to the outlet structure 12 via a pipeline. When the ship is sailing using inertia, the drive mechanism 13 drives the inlet structure 11 and the outlet structure 12 to extend outside the hull 100. Seawater enters the pipeline through the inlet structure 11, then enters the kinetic energy generating device to do work, causing the kinetic energy generating device to move, which in turn drives the power generation device to move. Afterward, the seawater flows out through the outlet structure 12. When the ship is sailing using inertia, seawater continuously enters the kinetic energy generating device to do work, and then flows out through the outlet structure 12, forming a circulation loop. During the circulation process, the seawater continuously does work, and the power generation device continuously generates kinetic energy.

[0025] As the ship's speed decreases, the flow of seawater into the intake structure 11 gradually decreases, and the mechanical energy generated gradually decreases until the ship stops sailing, at which point the kinetic energy generating device stops operating.

[0026] In this embodiment, the water inlet structure 11 can be a water inlet pipe, and the water outlet structure 12 can be a water outlet pipe. Both the water inlet pipe and the water outlet pipe are connected to the kinetic energy generating device through pipelines. The drive mechanism 13 can be a hydraulic cylinder or a pneumatic cylinder. When the drive mechanism 13 extends or retracts, it can drive the water inlet structure 11 and the water outlet structure 12 to extend or retract, so that the water inlet structure 11 and the water outlet structure 12 are located outside the cabin 100.

[0027] like Figure 1 As shown, in the embodiments of the present invention, both the inlet of the water inlet structure 11 and the outlet of the water outlet structure 12 are provided with filter screens 14 to prevent large impurities in the water from entering the gravity flow generator and affecting the operation of the kinetic energy generator.

[0028] Furthermore, the gravity flow generating device also includes a pair of housings 15 located inside the cabin 100. The water inlet structure 11 and the water outlet structure 12 are respectively disposed in one housing 15. The drive mechanism 13 passes through the housing 15 and is connected to the water inlet structure 11 and the water outlet structure 12.

[0029] Specifically, when the ship is in normal navigation, the inlet structure 11 and the outlet structure 12 are each located within a shell 15 to reduce resistance. In this embodiment, the shell 15 is located within the cabin 100 and is fixed. The shell 15 is composed of multiple plates, and the bottom plate 151 of the shell 15 is rotatably connected to the side plates. When the ship is sailing under inertial conditions, the drive mechanism drives the inlet structure 11 and the outlet structure 12 to push open the bottom plate 151 and extend them outside the cabin 100; while when the ship is in normal navigation, the drive mechanism drives the inlet structure 11 and the outlet structure 12 to retract into the shell 15, and the free end of the bottom plate 151 automatically abuts against the side plates to enclose the inlet structure 11 and the outlet structure 12 within the shell 15.

[0030] like Figure 1 As shown, in an embodiment of the present invention, the kinetic energy generating device includes: a water turbine unit, a meshing gear set, and a main shaft 45. The meshing gear set is sleeved on the outside of the main shaft 45. The water turbine unit is connected to the pipeline and the meshing gear set, and the main shaft 45 is connected to the power generation device.

[0031] Specifically, when the ship is sailing by inertia, seawater enters the turbine unit through the water intake structure 11. When the seawater flows through the turbine unit, it drives the meshing gear set to rotate, which in turn drives the main shaft 45 to rotate. The main shaft 45 drives the power generation device to move and generate electricity.

[0032] Furthermore, the meshing gear set includes: a first gear 43 and a second gear 44, the first gear 43 is connected to the turbine unit, the first gear 43 meshes with the second gear 44, and the second gear 44 is connected to the main shaft 45.

[0033] Specifically, when seawater flows through the turbine unit, it drives the turbine unit to rotate, which in turn drives the first gear 43 to rotate. The first gear 43 drives the second gear 44 to rotate, and the second gear 44 drives the main shaft 45 to rotate, which in turn drives the power generation device to move and generate electricity.

[0034] like Figure 1 As shown, in an embodiment of the present invention, the turbine unit includes a first turbine 41 and a second turbine 42. The pipeline includes an inlet pipe 21, a first branch pipe 22, a second branch pipe 23, and an outlet pipe 24. The first end of the inlet pipe 21 is connected to a gravity flow generator, and the second end of the inlet pipe 21 is connected to the first branch pipe 22 and the second branch pipe 23. The first branch pipe 22 is connected to the first turbine 41, the second branch pipe 23 is connected to the second turbine 42, and the outlet pipe 24 is connected to both the first turbine 41 and the second turbine 42.

[0035] Specifically, seawater flows into the inlet pipe 21 through the inlet structure 11, then enters the first turbine 41 through the first branch pipe 22, and enters the second turbine 42 through the second branch pipe 23. The seawater drives the first turbine 41 and the second turbine 42 to rotate, which in turn drives the first gear 43 and the second gear 44 to rotate. The seawater is discharged into the sea through the outlet pipe 24.

[0036] Furthermore, in an embodiment of the present invention, the ship kinetic energy recovery system further includes: a pair of switching valves 31 and a pair of regulating valves 32, the pair of switching valves 31 being respectively disposed in the inlet pipe 21 and the outlet pipe 24, and the pair of regulating valves 32 being respectively disposed in the first branch pipe 22 and the second branch pipe 23.

[0037] Specifically, the on / off valve 31 is used to control the opening and closing of the inlet pipe 21 and the outlet pipe 24, and the regulating valve 32 is used to regulate the flow rate of seawater entering the first turbine 41 and the second turbine 42. When the power generation unit supplies power to different electrical devices, the different electrical devices have different power requirements. By adjusting the regulating valve 32, the flow rate of seawater entering the first turbine 41 and the second turbine 42 can be adjusted to regulate the electrical energy generated by the power generation unit.

[0038] like Figure 1 As shown, in an embodiment of the present invention, there are multiple turbine units, each turbine unit is connected to a meshing gear set, and the multiple meshing gear sets are all sleeved with the main shaft 45.

[0039] Specifically, the water intake structure 11 is connected to multiple water intake pipes 21, and each water intake pipe 21 is connected to a turbine unit via a first branch pipe 22 and a second branch pipe 23. Seawater enters each turbine unit through the water intake structure 11, driving the multiple turbine units to rotate, which in turn drives each meshing gear set to rotate. The rotation of the meshing gear set drives the main shaft 45 to rotate, which in turn drives the power generation device to move and generate electricity.

[0040] In this embodiment, the flow rate of seawater entering each turbine can be adjusted according to power supply requirements to achieve different operating power levels. Simultaneously, when the ship's speed is high, the valve core opening of regulating valve 32 can be increased to increase the seawater flow rate into the turbine; conversely, when the ship's speed is low, the valve core opening of regulating valve 32 can be decreased to reduce the seawater flow rate into the turbine. This adapts to the kinetic energy recovery power level as the ship's speed gradually decreases, ensuring smooth and safe operation of the ship's kinetic energy recovery system. Furthermore, the independent operation of each turbine unit enhances the reliability of the ship's kinetic energy recovery system and facilitates maintenance in case of individual turbine unit failure, further improving the overall operational efficiency of the ship's kinetic energy recovery system.

[0041] It should be noted that when the ship is in normal navigation, both the switch valve 31 and the regulating valve 32 are closed, and the entire ship kinetic energy recovery system has no impact on the ship's operation. The ship kinetic energy recovery system only works when the ship is sailing using inertia.

[0042] like Figure 1 As shown, in an embodiment of the present invention, the power generation device includes a generator 51 and a rectifier 52. The generator 51 is connected to a main shaft 45, and the rectifier 52 is connected to the generator 51. When the main shaft 45 rotates, it can drive the generator 51 to generate electricity. The electrical energy is rectified by the rectifier 52 to form electrical energy that meets the user's needs, and is provided to the power supply equipment through the power supply network 53.

[0043] The ship kinetic energy recovery system provided in this invention embodiment is based on gravity circulation technology. Seawater is introduced into the turbine unit through a gravity-flow generator, increasing the ship's resistance during forward movement and achieving an auxiliary braking effect. Simultaneously, the introduced seawater drives the turbine to perform work, converting kinetic energy into mechanical energy, which is then converted into electrical energy by a generator. This fully utilizes the excess kinetic energy during the deceleration and stopping of large ships, improving the economic efficiency of large ship operation. Furthermore, the use of distributed turbines enhances the adjustability of the power level during kinetic energy recovery, allowing the process to adapt to changes in ship speed. It also provides greater flexibility in equipment setup and subsequent maintenance, further improving the efficiency of the ship kinetic energy recovery system.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
