Description

Technical Field

[0001] The present invention relates to the technical field of energy recovery, and in particular to a ship kinetic energy recovery system. Background Art

[0002] When large ships encounter emergencies and need to avoid obstacles or dock at ports, they need to slow down or stop sailing. Large ships such as oil tankers and cargo ships have great inertia due to their heavy weight. To overcome their own inertia and slow down or stop the ship, a lot of energy is consumed to provide reverse thrust. Usually, the propulsion propeller is reversed and auxiliary tugboats are used to slow down and stop the ship. This process requires a lot of additional energy, which further increases the energy consumption of large ships and reduces the economic efficiency of large ships. If the large inertia characteristics of the ship and the power that cannot be used during deceleration and stopping can be fully utilized, the economy of large ships will be improved.

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Combine the following Figure 1 A kinetic energy recovery system for a ship according to the present invention is described.

[0020] like Figure 1As shown, in an embodiment of the present invention, a ship kinetic energy recovery system includes: a gravity generating device, a kinetic energy generating device and a power generation device. The gravity generating device forms a circulation loop with the kinetic energy generating device through a pipeline, and the power generation device is connected to the kinetic energy generating device. The gravity generating device has a switchable first position and a second position. When the ship is in a navigation state, the gravity generating device is in the first position, and the gravity generating device is located in the cabin 100. When the ship is in a state of navigation using inertia, the gravity generating device is in the second position, and the gravity generating device is located outside the cabin 100. Seawater enters the kinetic energy generating device from the gravity generating device to drive the kinetic energy generating device to move, thereby driving the power generation device to operate to generate electrical energy.

[0021] Specifically, when the ship is sailing normally, the gravity generating device is located in the first position, that is, the gravity generating device is located in the cabin 100 to reduce the resistance of the ship when sailing; when the ship is docked, due to the large inertia of the ship, even if the power system stops working, the ship will continue to sail for a certain distance. At this time, the gravity generating device extends outside the cabin 100 and is in the second position. The gravity generating device is immersed in seawater. Since the flow direction of seawater is opposite to the navigation direction of the ship, seawater flows into the gravity generating device by gravity, and the seawater enters the kinetic energy generating device along the pipeline, driving the kinetic energy generating device to move, and the kinetic energy generating device drives the power generating device to move to generate electrical energy. The electrical energy can be used by electrical equipment on the ship to improve the economy of the ship.

[0022] The ship kinetic energy recovery system provided by the embodiment of the present invention, by providing a gravity generating device, a kinetic energy generating device and a power generating device, can utilize the inertia of the ship to allow seawater to flow into the gravity generating device and the kinetic energy generating device by gravity when the ship is at a standstill, thereby driving the kinetic energy generating device to move, so that the power generating device moves to generate electrical energy to supply electrical equipment on the ship, thereby reducing the energy consumption of the ship and improving the economy of large ships.

[0023] 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 driving mechanism 13. The inlet structure 11 is connected to the kinetic energy generating device through a pipeline, and the kinetic energy generating device is connected to the outlet structure 12 through a pipeline. When the ship uses inertia to navigate, the driving mechanism 13 drives the inlet structure 11 and the outlet structure 12 to extend outside the cabin 100, and the seawater enters the pipeline from the inlet structure 11, and then enters the kinetic energy generating device to do work, so that the kinetic energy generating device moves, and then drives the power generation device to move, and then the seawater flows out from the outlet structure 12. When the ship uses inertia to navigate, seawater continuously enters the kinetic energy generating device to do work, and then flows out from the outlet structure 12 to form a circulation loop. During the circulation process, the seawater continues to do work and the power generation device continues to generate kinetic energy.

[0024] As the speed of the ship decreases, the flow of seawater entering the water intake structure 11 gradually decreases, and the generated mechanical energy gradually decreases, until the ship stops sailing and the kinetic energy generating device stops running.

[0025] 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, and the water inlet pipe and the water outlet pipe are both connected to the kinetic energy generating device through pipelines. The driving mechanism 13 can be an oil cylinder or an air cylinder, and when the driving mechanism 13 is extended or retracted, 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.

[0026] like Figure 1 As shown, in an embodiment of the present invention, a filter screen 14 is provided at the water inlet of the water inlet structure 11 and the water outlet of the water outlet structure 12 to prevent larger impurities in the water from entering the gravity generating device and affecting the operation of the kinetic energy generating device.

[0027] Furthermore, the gravity flow generating device also includes a pair of shells 15, which are located in the cabin 100, the water inlet structure 11 and the water outlet structure 12 are respectively arranged in one shell 15, and the driving mechanism 13 passes through the shell 15 and is connected with the water inlet structure 11 and the water outlet structure 12.

[0028] Specifically, when the ship is in a normal navigation state, the water inlet structure 11 and the water outlet structure 12 are respectively located in a shell 15 to reduce resistance. In this embodiment, the shell 15 is located in the cabin 100, and the shell 15 is fixed. The shell 15 is surrounded by a plurality of plates, and the bottom plate 151 of the shell 15 is rotatably connected to the side plate. When the ship is sailing in an inertial state, the driving mechanism drives the water inlet structure 11 and the water outlet structure 12 to push open the bottom plate 151 and extend outside the cabin 100; and when the ship is in a normal navigation state, the driving mechanism drives the water inlet structure 11 and the water outlet structure 12 to be retracted into the shell 15, and the free end of the bottom plate 151 automatically abuts against the side plate to enclose the water inlet structure 11 and the water outlet structure 12 in the shell 15.

[0029] like Figure 1 As shown, in an embodiment of the present invention, the kinetic energy generating device includes: a turbine unit, a meshing gear unit and a main shaft 45, the meshing gear unit is sleeved on the outside of the main shaft 45, the turbine unit is connected to the pipeline and the meshing gear unit, and the main shaft 45 is connected to the power generation device.

[0030] Specifically, when the ship uses inertia to navigate, 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, and then drives the main shaft 45 to rotate. The main shaft 45 drives the power generation device to move and generate electrical energy.

[0031] Furthermore, the meshing gear set includes: a first gear 43 and a second gear 44 , the first gear 43 is connected to the turbine set, the first gear 43 meshes with the second gear 44 , and the second gear 44 is connected to the main shaft 45 .

[0032] Specifically, when seawater flows through the turbine unit, it drives the turbine unit to rotate, and then drives the first gear 43 to rotate, the first gear 43 drives the second gear 44 to rotate, the second gear 44 drives the main shaft 45 to rotate, and then drives the power generation device to move and generate electricity.

[0033] 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 pipeline 21, a first branch pipeline 22, a second branch pipeline 23 and an outlet pipeline 24. The first end of the inlet pipeline 21 is connected to the gravity generating device, the second end of the inlet pipeline 21 is connected to the first branch pipeline 22 and the second branch pipeline 23, the first branch pipeline 22 is connected to the first turbine 41, the second branch pipeline 23 is connected to the second turbine 42, and the outlet pipeline 24 is connected to the first turbine 41 and the second turbine 42.

[0034] Specifically, seawater flows into the water inlet pipe 21 through the water inlet structure 11, then enters the first water turbine 41 through the first branch pipe 22, and enters the second water turbine 42 through the second branch pipe 23. The seawater drives the first water turbine 41 and the second water turbine 42 to rotate, and then drives the first gear 43 and the second gear 44 to rotate. The seawater is discharged into the sea through the water outlet pipe 24.

[0035] Furthermore, in an embodiment of the present invention, the ship kinetic energy recovery system also includes: a pair of switch valves 31 and a pair of regulating valves 32, the pair of switch valves 31 are respectively arranged in the water inlet pipeline 21 and the water outlet pipeline 24, and the pair of regulating valves 32 are respectively arranged in the first branch pipeline 22 and the second branch pipeline 23.

[0036] Specifically, the switch valve 31 is used to control the on / off of the water inlet pipe 21 and the water outlet pipe 24, and the regulating valve 32 is used to adjust the flow of seawater entering the first water turbine 41 and the second water turbine 42. When the power generation device supplies power to different electrical equipment, different electrical equipment has different power requirements. By adjusting the regulating valve 32, the flow of seawater entering the first water turbine 41 and the second water turbine 42 can be adjusted to adjust the electrical energy generated by the power generation device.

[0037] like Figure 1 As shown, in the embodiment of the present invention, there are multiple water turbine sets, each of which is connected to a meshing gear set, and the multiple meshing gear sets are all sleeved with the main shaft 45.

[0038] Specifically, the water inlet structure 11 is connected to a plurality of water inlet pipelines 21, and each water inlet pipeline 21 is connected to a water turbine unit through a first branch pipeline 22 and a second branch pipeline 23. Seawater enters each water turbine unit from the water inlet structure 11, driving the plurality of water turbine units to rotate, and then driving each meshing gear unit to rotate, and the rotation of the meshing gear unit drives the main shaft 45 to rotate, and then drives the power generation device to move and generate electrical energy.

[0039] In this embodiment, the flow of seawater entering each turbine can be adjusted according to the power supply demand to achieve the adjustment of different operating power levels. At the same time, when the ship's speed is fast, the valve core opening of the regulating valve 32 can be increased to increase the flow of seawater entering the turbine; when the ship's speed is low, the valve core opening of the regulating valve 32 can be reduced to reduce the flow of seawater entering the turbine, so as to adapt to the kinetic energy recovery power level of the ship during the process of gradually reducing the speed, so that the ship's kinetic energy recovery system can operate smoothly and safely; on the other hand, each turbine unit operates independently, so that the ship's kinetic energy recovery system has better reliability, and it is also easy to repair when a single turbine unit fails, which can further improve the operating efficiency of the entire ship's kinetic energy recovery system.

[0040] It should be noted that: when the ship is in a normal navigation state, the switch valve 31 and the regulating valve 32 are both closed, and the entire ship kinetic energy recovery system has no effect on the operation of the ship. The ship kinetic energy recovery system will only work when the ship uses inertia to navigate.

[0041] like Figure 1 As shown, in the embodiment of the present invention, the power generation device includes: a generator 51 and a rectifier 52, the generator 51 is connected to the 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 run and generate electricity, and the electric energy is converted into electric energy that meets the user's needs after passing through the rectifier 52, and is provided to the power supply equipment through the power supply network 53.

[0042] The ship kinetic energy recovery system provided by the embodiment of the present invention is based on the gravity circulation technology. Seawater is introduced into the turbine unit through a gravity generating device, so that the resistance of the ship increases during the forward movement, thereby achieving the effect of auxiliary braking; at the same time, the introduced seawater drives the turbine to do work, converts kinetic energy into mechanical energy, and then converts it into electrical energy through a generator, thereby making full use of the excess kinetic energy during the deceleration and stop of large ships, thereby improving the economy of the operation of large ships. On the other hand, the use of distributed turbines improves the adjustability of the power level during the kinetic energy recovery process, so that the process can fully adapt to the changes in ship speed, and has better flexibility in equipment and subsequent maintenance, further improving the efficiency of the ship's kinetic energy recovery system.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
