[0022] Offshore aquaculture vessels are a type of ship equipment used to cultivate deep-sea aquaculture in deep sea areas. Offshore aquaculture vessels need to inject seawater from the deep sea into the aquaculture cabin inside the hull and maintain a temperature and environment similar to that of the deep sea, so that different types of aquatic products can be cultivated in the aquaculture cabin. In the prior art, since there are abundant water kinetic energy resources such as sea waves and currents at sea, how to recycle and utilize their water kinetic energy and use it as a source of electricity for offshore aquaculture vessels has considerable development prospects.

[0023] In order to solve the above technical problems, the present invention proposes a water kinetic energy recovery system and an offshore aquaculture vessel.

[0024] See also Figure 1-2 In one embodiment of the present invention, the water kinetic energy recovery system is applied to an offshore aquaculture vessel (not shown in the drawings); specifically, the water kinetic energy recovery system comprises: Propeller assembly 100; A power assembly 200, the power assembly 200 is used to drive the propeller assembly 100 to rotate forward to drive the marine aquaculture vessel to travel; The energy storage assembly 300 is used to utilize the reverse rotation of the propeller assembly 100 due to the sea wave and current as a power source to generate electricity and store energy; The displacement drive assembly 400 is used to drive the propeller assembly 100 to move to the first position or the second position; when the propeller assembly 100 moves to the first position, the propeller assembly 100 is connected to the power assembly 200; when the propeller assembly 100 moves to the second position, the propeller assembly 100 is connected to the energy storage assembly 300.

[0025] The technical solution of the present invention is to set the propeller assembly 100 to a structure capable of forward and reverse rotation; and to provide a displacement drive assembly 400, which is used to drive the propeller assembly 100 to move to the first position or the second position; as shown in the attached Figure 1 As shown in the figure, when the propeller assembly 100 moves to the first position so that the propeller assembly 100 is connected to the power assembly 200, the power assembly 200 can drive the propeller assembly 100 to rotate forward to drive the marine aquaculture vessel to travel; when the marine aquaculture vessel travels to the designated marine aquaculture area, as shown in the figure Figure 2 As shown, the propeller assembly 100 is moved to the second position to connect the propeller assembly 100 with the energy storage assembly 300. At this time, the energy storage assembly 300 can use the reversal of the propeller assembly 100 caused by the action of waves and currents as a power source to generate electricity and store energy; thereby achieving the ability to recycle water kinetic energy such as waves and currents and use it as a source of electricity for offshore aquaculture vessels.

[0026] Specifically, the propeller assembly 100 includes a rotating seat 110, and a plurality of propeller blades 120 equidistantly mounted on the circumferential side of the rotating seat 110; the rotating seat 110 is provided with a rotating rod 130 extending axially, and one end of the rotating rod 130 away from the rotating seat 110 is movably connected to the offshore aquaculture vessel. In this way, the rotating rod 130 is movably connected to the offshore aquaculture vessel so that the propeller assembly 100 can be installed on the offshore aquaculture vessel. It can be understood that since the rotating rod 130 in the present application has two motion modes, namely sliding and rotating, the connection between the rotating rod 130 and the offshore aquaculture vessel is a combination of rotating connection and sliding connection. For example, the rotating rod 130 can be first installed on the rotating bearing 150, and then the rotating bearing 150 can be slidably connected to the bearing seat (not shown in the drawings) of the offshore aquaculture vessel, so as to achieve the purpose that the rotating rod 130 can be both rotatable and slidable relative to the offshore aquaculture vessel.

[0027] There are many specific structures of the power assembly 200. Figure 1-4The power assembly 200 includes a rotary drive device 210 and a first sleeve member 220, wherein the rotary drive device 210 is fixedly connected to the offshore aquaculture vessel, and the first sleeve member 220 is rotatably connected to the offshore aquaculture vessel; the first sleeve member 220 is coaxially sleeved on the outer side of the rotating rod 130, and a preset gap 230 is provided between the inner wall of the first sleeve member 220 and the outer side of the rotating rod 130; a first bevel gear ring 221 is fixedly sleeved on the side of the first sleeve member 220; a first bevel gear 211 is connected to the driving end of the rotary drive device 210, and the first bevel gear 211 is meshedly connected with the first bevel gear ring 221. In this way, when the propeller assembly 100 is located in the first position, the rotation drive device 210 is used as the power source, and the meshing transmission structure of the first bevel gear 211 and the first bevel gear ring 221 is used to enable the rotation drive device 210 to drive the first sleeve member 220 to rotate, thereby using the first sleeve member 220 to drive the rotating seat 110 to rotate, and the rotation of the rotating seat 110 drives the propeller blades 120 to rotate forward, and the water thrust generated by the forward rotation of the propeller blades 120 is used to drive the offshore aquaculture vessel forward. The structure is simple and practical.

[0028] At the same time, since there is a preset gap 230 between the inner wall of the first sleeve member 220 and the outer side of the rotating rod 130, that is, the first sleeve member 220 and the rotating rod 130 do not interfere with each other, when the propeller assembly 100 is in the second position, during the process of the rotating seat 110 driving the rotating rod 130 to reverse, the first sleeve member 220 is not affected by the rotating rod 130 and rotates accordingly, thereby avoiding the first sleeve member 220 driving the driving end of the rotating drive device 210 to reverse and causing damage to the rotating drive device 210.

[0029] Furthermore, the interior of the preset gap 230 is filled with a plurality of ball members 240, and the plurality of ball members 240 fit closely with the first sleeve member 220 and the rotating rod 130 and are movably connected to each other. In view of this arrangement, since in the above structure there is a preset gap 230 between the inner wall of the first sleeve member 220 and the outer side of the rotating rod 130, in order to better support the rotating rod 130 and improve the stability of the rotating rod 130, the present embodiment fills a plurality of ball members 240 in the preset gap 230. The ball members 240 are used to support the rotating rod 130 on the one hand, and on the other hand, the ball members 240 themselves can rotate to offset the rotation of the rotating rod 130, so that the rotation of the rotating rod 130 will not be transmitted to the first sleeve member 220, thereby ensuring that the rotation between the first sleeve member 220 and the rotating rod 130 interferes with each other, thus killing two birds with one stone.

[0030] Furthermore, the first sleeve member 220 is provided with a limit ring 250 at both axial ends, the inner side of the limit ring 250 is used for the rotation rod 130 to pass through, and the limit ring 250 is used to limit the ball member 240 inside the preset gap 230. In this way, the limit ring 250 is used to limit the ball member 240 inside the preset gap 230 to prevent the ball member 240 from falling from the first sleeve member 220.

[0031] There are many specific structures of the energy storage assembly 300. Figure 1-4 The energy storage assembly 300 includes an energy storage power generation device 310 and a second sleeve member 320, wherein the energy storage power generation device 310 is fixedly connected to the offshore aquaculture vessel, and the second sleeve member 320 is rotatably connected to the offshore aquaculture vessel; the second sleeve member 320 is coaxially sleeved on the outer side of the rotating rod 130, and the inner side of the second sleeve member 320 is provided with a plurality of axial grooves 322 arranged along the axial direction thereof; the outer side of the rotating rod 130 is provided with a plurality of axial ridges 131 arranged along the axial direction thereof, and the axial ridges 131 are slidably connected to the axial grooves 322; when When the propeller assembly 100 moves to the first position, the axial ridge 131 slides to the outside of the axial groove 322; when the propeller assembly 100 moves to the second position, the axial ridge 131 slides to the inside of the axial groove 322, so that the rotating rod 130 can drive the second sleeve member 320 to rotate; the side fixed sleeve of the second sleeve member 320 is equipped with a second bevel gear ring 321; the driving end of the energy storage and power generation device 310 is connected to the second bevel gear 311, and the second bevel gear 311 is meshed with the second bevel gear ring 321. In this way, when the propeller assembly 100 is in the second position, during the process of the propeller assembly 100 being reversed by the sea waves and currents, the axial ridge 131 slides into the inside of the axial groove 322 at this time, so that the rotating rod 130 can drive the second sleeve member 320 to rotate; then, through the meshing transmission structure of the second bevel gear 311 and the second bevel gear ring 321, the driving end of the energy storage and power generation device 310 is rotated to generate electricity and store energy, thereby achieving the recovery and utilization of water kinetic energy such as sea waves and currents.

[0032] In addition, refer to the attached Figure 6 In order to ensure that the axial ridge 131 of the rotating rod 130 can smoothly slide into the axial groove 322 of the second sleeve member 320 when the propeller assembly 100 moves from the first position to the second position; a guide channel 323 with a conical structure can be provided at the end of the axial groove 322, and an arc transition can be provided at the connection between two adjacent guide channels 323 to ensure that the axial ridge 131 can drive the rotating rod 130 to rotate slightly along the inclined edge of the guide channel 323, thereby ensuring that the axial ridge 131 can smoothly slide into the axial groove along the inclined edge, so that the rotating rod 130 and the second sleeve member 320 are combined to form a whole.

[0033] Furthermore, the power supply end of the rotation driving device 210 of the power assembly 200 is connected to the energy storage power generation device; with this arrangement, the electric energy generated by the energy storage power generation device is used as the power source of the rotation driving device 210, achieving self-production and self-sufficiency.

[0034] Furthermore, the power supply end of the rotation drive device 210 of the power assembly 200 is connected to the external power supply device 500, and the external power supply device 500 includes a wind power generation device and / or a photovoltaic power generation device. In this way, in addition to using water kinetic energy as a power source, this embodiment also uses wind power and solar energy, which are renewable energy sources, as power sources to ensure that the rotation drive device 210 has sufficient power source to drive the propeller assembly 100 to operate, and is also beneficial to energy saving and environmental protection.

[0035] There are many specific structures of the displacement drive assembly 400. Figure 1-5 The displacement driving device includes a first magnetic member 410 and a second magnetic member 420, the first magnetic member 410 is installed at the end of the rotating seat 110 facing the first sleeve member 220, and the second magnetic member 420 is installed at the end of the first sleeve member 220 facing the rotating seat 110; the displacement driving device also includes a magnetic control device, and the magnetic control device is used to switch the second magnetic member 420 to a first magnetic state or a second magnetic state; when the second magnetic member 420 is switched to the first magnetic state, the first magnetic member 410 and the second magnetic member 420 attract each other to drive the rotating seat 110 to move to fit with the first sleeve member 220, thereby moving the propeller assembly 100 to the first position; when the second magnetic member 420 is switched to the second magnetic state, the first magnetic member 410 and the second magnetic member 420 repel each other to drive the rotating seat 110 to move to separate from the first sleeve member 220, thereby moving the propeller assembly 100 to the second position. In this configuration, the magnetic attraction or repulsion between the first magnetic component 410 and the second magnetic component 420 is used as the displacement power source of the propeller assembly 100, and the structure is simple and practical. It can be understood that, taking the first magnetic component 410 as an example of N-pole polarity, the second magnetic component 420 in the first magnetic state is S-pole polarity, and the first magnetic component 410 and the second magnetic component 420 are attracted to each other according to the principle of opposites attracting; the second magnetic component 420 in the second magnetic state is N-pole polarity, and the first magnetic component 410 and the second magnetic component 420 are repelled from each other according to the principle of likes repelling. How to switch the magnetic state of the second magnetic component 420 belongs to the prior art, so this application will not elaborate on its structure in detail.

[0036] Specifically, As attached Figure 1As shown, when the propeller assembly 100 needs to be moved to the first position, the second magnetic member 420 is switched to the first magnetic state, at which time the first magnetic member 410 and the second magnetic member 420 attract each other, thereby driving the rotating seat 110 to approach the first sleeve member 220 until the two fit together, so that the rotating seat 110 and the first sleeve member 220 are combined to form a whole. Then the rotary drive device 210 drives the first sleeve member 220 to rotate, and the rotating seat 110 rotates forward accordingly, and the water propulsion force generated by the forward rotation of the propeller blades 120 drives the marine aquaculture boat forward. At the same time, because the axial ridge 131 slides to the outside of the axial groove 322 at this time, the forward rotation of the rotating rod 130 cannot drive the second sleeve member 320 to rotate, that is, at this time the energy storage power generation device 310 is in a standby state.

[0037] As attached Figure 2 As shown, when the propeller assembly 100 needs to be moved to the second position, the second magnetic member 420 is switched to the second magnetic state. At this time, the first magnetic member 410 and the second magnetic member 420 repel each other, thereby driving the rotating seat 110 away from the first sleeve member 220 until the two are separated from each other; at the same time, since there is a preset gap 230 between the inner wall of the first sleeve member 220 and the outer side of the rotating rod 130, that is to say, the first sleeve member 220 and the rotating rod 130 do not interfere with each other, so when the rotating rod 130 is reversed by the force of the sea wave current, the first sleeve member 220 is not affected by the rotating rod 130 and rotates accordingly, so as to avoid the first sleeve member 220 driving the driving end of the rotating drive device 210 to reverse and cause damage to the rotating drive device 210. At the same time, since the axial ridge 131 slides into the inside of the axial groove 322 at this time, the rotating rod 130 can drive the second sleeve member 320 to rotate by utilizing the concave-convex fit between the axial ridge 131 and the axial groove, so that the driving end of the energy storage and power generation device 310 rotates and generates electricity and stores energy.

[0038] Furthermore, a plurality of protrusions 140 are provided at the end of the rotating seat 110 facing the first sleeve member 220, and the plurality of protrusions 140 are distributed in a ring shape at equal distances around the axis of the rotating rod 130; a plurality of recessed hole portions 260 are provided at the end of the first sleeve member 220 facing the rotating seat 110, and the plurality of protrusions 140 are distributed in a ring shape at equal distances around the axis of the rotating rod 130; when the propeller assembly 100 moves to the first position, the protrusions 140 and the recessed hole portions 260 are engaged with each other, so that the first sleeve member 220 can drive the rotating seat 110 to rotate. In order to ensure that the first sleeve member 220 can drive the rotating seat 110 to rotate, the present embodiment respectively provides a protrusion 140 and a recessed hole portion 260 on the rotating seat 110 and the first sleeve member 220. When the rotating seat 110 and the first sleeve member 220 are in contact with each other, the protrusion 140 and the recessed hole portion 260 are fitted together; thereby utilizing the concave-convex transmission between the protrusion 140 and the recessed hole portion 260 to ensure that the first sleeve member 220 can effectively drive the rotating seat 110 to rotate.

[0039] Furthermore, the first sleeve member 220 is provided with a plurality of inclined channels 270 at the end portion facing the rotating seat 110, and each section of the inclined channel 270 is respectively provided between two adjacent recessed hole portions 260; the inclined track of each section of the inclined channel 270 is inclined along the clockwise or counterclockwise direction of the first sleeve member 220, so that the protrusion 140 can slide along the inclined channel 270 until it is interlocked with the recessed hole portion 260. In this way, in order to ensure that when the rotating seat 110 and the first sleeve member 220 are fitted together, the protrusion 140 and the recessed hole portion 260 can be interlocked and matched with each other, the present embodiment provides an inclined channel 270 between two adjacent recessed hole portions 260, so that the protrusion 140 can slide along the inclined surface of the inclined channel 270 into the recessed hole portion 260, thereby ensuring that the protrusion 140 and the recessed hole portion 260 are interlocked with each other, so as to ensure the smooth implementation of the technical solution of the present application.
