Description

Technical Field

[0001] The invention relates to an underwater power generation device, in particular to an automatic power generation device utilizing the energy of fish swimming. Background Art

[0002] The long-term operation of underwater robots and submersibles has been plagued by insufficient energy sustainability. Taking advantage of on-site underwater energy generation is one of the effective solutions. Underwater power generation devices can be roughly divided into two categories. One is to use the natural energy contained in seawater to generate electricity, including waves, temperature differences, concentration differences and other forms of power generation, such as "A deep-sea self-fixed wave power generation device" (CN201611214809.X), "A seawater temperature difference power generation circulation system based on a single screw expander" (CN201921796733.5), and the Korean patent "Electric Energy Conversion System for Salinity Gradient Power Generation" (KR1020210101222). Due to the limitations of the ocean hydrological distribution, this type of power generation device generally requires a larger size and working span, and the deployment area is also relatively fixed, which is used for equipment with poor flexibility in high-power charging. Another type of underwater power generation is to use underwater biological energy to generate electricity, such as "A device and method for enriching and multi-level purification of deep-sea microorganisms in a high-pressure environment" (CN202210266114.5). This patent provides a millivolt-level power generation device with low power, which can only meet the needs of low-power equipment such as sensors. The considerable energy generated by the movement of fish can fully meet the high-power supply of underwater equipment, but currently only one invention under review by China Power Construction Group Guiyang Survey and Design Institute Co., Ltd., "A fishway power generation integrated system" (CN116877315A, application date 2023-10-13), is retrieved. The device relies on the inherent migratory fishway of the river dam, and arranges dispersed turbines on the side walls of the fishway to achieve the use of the water flow driven by the migrating fish in the fishway to impact the turbine for power generation. However, the device has the following shortcomings:

[0003] (1) It is not portable and flexible to obtain energy, and has poor applicability. It can only be built on river dams, with fixed power generation sites and limited by the migration season, and cannot generate electricity continuously. It is especially difficult to capture the energy of fish swimming in deep sea areas to power marine equipment at any time.

[0004] (2) Energy utilization is inefficient and extensive. It can only utilize the energy of fast water flow driven by a large number of fish swimming together, and is inefficient in collecting energy from the swimming of a single fish. In addition, the device has a single power generation function and can only collect wake energy through a turbine. The swimming propulsion of fish accounts for the main part of the energy of fish swimming, and the device cannot convert this part to generate energy. Summary of the invention

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations.

[0040] The present application embodiment discloses an underwater power generation device, such as Figure 1As shown, it includes a fish swimming channel base 1, a fish swimming channel top cover 2, an underwater camera 3, a fish screening gate 4, a fish catching and attracting light 5, a memory telescopic mechanism 6, a fish suction plate 7, a telescopic fish cover 8, a follow-up turbine generator 9, a wire towline 10, a motor base 11, a fish swimming tail energy collector 12, a fish driving and attracting light 13, an ultrasonic fish driving generator 14, a power transmission-control cable 15, a transmission support frame 16, an energy storage module 17, an intelligent integrated controller 18, an outer rotor assembly 19, an inner stator assembly 20, a fish suction plate 21, a fish suction plate frame 22, an electropolymer brush 23 and a magnetic steel pair I 24.

[0041] like Figure 1 As shown, the fish swimming channel base 1 and the fish swimming channel top cover 2 are annular structures, and annular channels are arranged on opposite sides of the fish swimming channel base 1 and the fish swimming channel top cover 2, and the fish swimming channel base 1 and the fish swimming channel top cover 2 are hinged. When the fish swimming channel base 1 and the fish swimming channel top cover 2 are rotated to relative to each other, the fish swimming channel base 1 and the fish swimming channel top cover 2 are locked, and the annular channels of the fish swimming channel base 1 and the fish swimming channel top cover 2 are opposite to each other to form a fish swimming channel.

[0042] like Figure 1 As shown, a driving device is arranged between the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel. The driving device is an electromagnetic switch. The electromagnetic switch is arranged on the base 1 of the fish-swimming flow channel and / or the top cover 2 of the fish-swimming flow channel, and is located near the hinged side of the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel; the electromagnetic switch generates suction or repulsion in different directions of power supply. When repulsion is generated, the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel are driven to open. When suction is generated, the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel are driven to close, and the electromagnetic switch locks the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel by suction. A limiting device is arranged between the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel to limit the maximum angle of opening between the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel, so as to avoid the opening angle being too large and unable to be closed by suction.

[0043] like Figure 1As shown, the fish-driven generator includes a motor base 11, an outer rotor assembly 19, an inner stator assembly 20, and a water-lubricated bearing. The fish-driven generator is connected to the center of the fish-swimming flow channel base 1 through a plurality of transmission support frames 16. The motor base 11 is fixedly connected to the fish-swimming flow channel base 1, the inner stator core and the coil 20 are fixedly connected to the motor base 11, and the inner stator assembly 20 is connected to the outer rotor assembly 19 through a water-lubricated bearing, and the outer rotor assembly 19 can rotate freely around the inner stator assembly 20. A fish-repelling and fish-luring lamp 13 and an ultrasonic fish-repelling generator 14 form a group of repelling components. A plurality of groups of fish tail energy collectors 12 and repelling components are sequentially arranged in the annular channel of the fish-swimming channel base 1 and the fish-swimming channel top cover 2, and the fish tail energy collectors 12 in the fish-swimming channel base 1 and the fish tail energy collectors 12 in the fish-swimming channel top cover 2 are arranged alternately; the repelling components and the fish tail energy collectors 12 in the annular channel of the fish-swimming channel base 1 are arranged alternately, and the repelling components and the fish tail energy collectors 12 in the annular channel of the fish-swimming channel top cover 2 are arranged alternately. The energy storage module 17 and the intelligent integrated controller 18 are both connected to the motor base 11. The fish tail energy collector 12 is a hydro-turbine generator, and the fish tail energy collector 12 is connected to the power transmission-control cable 15, and the other end of the power transmission-control cable 15 is connected to the energy storage module 17. The power transmission-control cable 15 can pass through the transmission support frame 16. When the fish swims in the fish swimming channel, the flowing seawater driven by the fish will drive the fish tail energy collector 12 to rotate, and the electricity generated by the fish tail energy collector 12 is transmitted to the energy storage module 17 for storage.

[0044] The base 1 of the fish-swimming flow channel is provided with a lower box body, and the top cover 2 of the fish-swimming flow channel is provided with an upper box body. When the base 1 of the fish-swimming flow channel and the top cover 2 of the fish-swimming flow channel are rotated to be relative to each other, the lower box body and the upper box body are opposite to each other to form a fishing box. The underwater camera 3 is connected to the outer side of the lower box body, and is used to detect the size of the fish so as to select the fish of the appropriate size to enter the fish-swimming flow channel; the fish-selecting door 4 and the telescopic fish cover 8 are installed on the lower box body, and the fish-selecting door 4 is rotatably connected to the base 1 of the fish-swimming flow channel through a rotatable hinge, and the hinge is attached with a miniature electromagnetic switch relay, and the fish-selecting door 4 is open when the power is on, and closed when the power is off.

[0045] like Figure 2As shown, the telescopic fish cover device 8 is composed of a soft cover 25, two fish cover brackets 26 and a magnetic steel pair II 27. The soft cover 25 is made of a composite material and can be telescopically deformed. The fish cover bracket 26 is a pair of rigid metal materials with a shape similar to a semi-elliptical circle, and the magnetic steel pair II 27 is a pair of strong magnetic steels with N and S poles respectively. One end of the soft cover 25 is fixedly connected to the middle of the board surface of the fish screening door 4, and the other end is connected to a pair of fish cover brackets 26, which support an approximately elliptical outline that can accommodate the fish body. The two fish cover brackets 26 are arranged relatively, and the magnetic steel pair II 27 is connected in the middle. The magnetic steel pair II 27 is matched with the magnetic poles of the layout magnetic steel pair I 24 on the fish suction plate 7. When the fish suction plate is close enough, the N pole and S pole of the magnetic steel pair I 24 and the magnetic steel pair II 27 are mutually attracted head to tail, and the strict magnetic suction force is used to ensure that the telescopic fish cover can be in the aligned and stretched state, and will not be twisted or entangled, so that the fish is trapped in the cover, and the suction action of the suction cup is not affected, that is, it approaches and adsorbs from the front to the fish belly. When the stretching fish cover is not close enough to the fish suction plate, it is shortened by the attraction between the magnetic steel pair I and the fish screening door.

[0046] The fish-catching and luring light 5 is arranged in the lower box body, so that when the fish-selecting door 4 is opened, the fish-catching and luring light 5 can be used to lure the fish into the lower box body.

[0047] like Figure 2 As shown, the adsorption system includes a memory expansion piece 6 and a fish suction plate 7, the fish suction plate 7 and the memory expansion piece 6 are integrated, the memory expansion piece 6 is made of shape memory metal, and the other end of the memory expansion piece 6 is slidably connected to the inner wall of the lower box body facing the fish gate 4 and the inner wall of the fish swimming channel base 1, so that the memory expansion piece 6 and the fish suction plate 7 can follow the fish in the fish swimming channel. The memory expansion piece 6 is provided with a temperature control component, the temperature control component includes a resistance wire and a temperature sensor, the temperature sensor is used to detect the temperature of the memory expansion piece 6, the resistance wire is arranged inside the memory expansion piece 6, and the resistance wire is connected to the energy storage module 17. When the fish enters the lower box, the fish screening door 4 is closed, and the temperature of the memory expansion sheet 6 is increased by the temperature control component, the memory expansion sheet 6 is extended, and the memory expansion sheet 6 drives the fish suction plate 7 to move, and the fish suction plate 7 applies a certain pressure to the fish belly, and the fish suction plate 7 quickly undergoes internal polymerization deformation to form suction. After the suction is detected, the temperature of the memory expansion sheet 6 is reduced by controlling the temperature control component, and the memory expansion sheet 6 can automatically shrink and become smaller. As the memory expansion sheet 6 shrinks, the magnetic steel pair I24 and the magnetic steel pair II27 are separated, and the magnetic steel pair II27 is re-adsorbed on the fish screening door 4 to save space and reduce the resistance when the fish swims. When it is detected that the top cover 2 of the fish swimming channel is opened, the suction cup is aggregated and deformed to reset, the adsorption force is eliminated, and the tired fish is released. Among them, the strong suction cup is adsorbed on the fish body, and the internal polymer shape is adjusted to achieve automatic adjustment of the suction force and separation from the fish body.

[0048] The follow-up hydro-turbine generator 9 is fixedly connected to the side of the fish suction plate 7 facing the memory expansion plate 6. The follow-up hydro-turbine generator 9 is fixedly connected to the outer rotor assembly 19 of the drag motor through the wire tow rope 10, so that the outer rotor assembly 19 rotates as the fish swims. The outer rotor assembly 19 is composed of an iron core, a coil, and a sealed shell covering the outside of the two. The energized wire of the wire tow rope 10 is connected to the coil in the outer rotor assembly 19 through a through-cabin sealed waterproof form. The wire tow rope 10 can withstand the force of the drag motor driven by the fish swimming to rotate, and can also transmit current. When the base 1 of the fish swimming channel and the top cover 2 of the fish swimming channel are locked, there is a gap between the base 1 of the fish swimming channel and the top cover 2 of the fish swimming channel, and the wire tow rope 10 passes through the gap. After the fish suction plate 7 attracts the fish, the fish swims in the fish swimming channel, driving the memory expansion plate 6, the fish suction plate 7 and the follower water turbine generator 9 to move together. During the movement, the water flow will impact the follower water turbine generator 9 to rotate and generate electricity. The electric energy is converted into direct current after rectification and inversion, and is transmitted to the coil in the outer rotor assembly 19 through the wire of the wire tow rope 10, and the wire tow rope 10 is pulled to drive the outer rotor assembly 19 to rotate. The coil in the outer rotor assembly 19 is wound on the magnetic core. After the coil receives the direct current generated by the follower water turbine generator 9, it generates a magnetic field and a magnetic circuit. The magnetic field and the magnetic circuit rotate with the follower outer rotor assembly 19 dragged by the fish, thereby periodically cutting the coil in the inner stator assembly 20 to achieve drag power generation. The electric energy is transmitted to the energy storage module 17 through the wire built into the drag motor base 11.

[0049] like Figure 3 As shown, the fish suction plate 7 includes a fish suction plate 21, a fish suction plate frame 22, an electric polymer brush 23 and a magnetic steel pair Ⅰ24. The fish suction plate frame 22 is connected to one end of the memory telescopic sheet 6. The fish suction plate 21 is provided with a groove to form an adsorption cavity with an eight-shaped texture. The cavity is evenly filled with a polymer brush 23. The polymer brush 23 is fixedly connected to the bottom of the adsorption cavity and is connected to the intelligent integrated controller 18 through a conductive cable built into the tow rope to realize intelligent control of the suction cup function. Each strand of the polymer brush is coated with a sealing enameled wire to ensure sealing and waterproofing. The magnetic steel pair Ⅰ24 is connected to the edge of the fish suction plate frame 22 facing the surface of the fish screening gate 4. The magnetic steel pair Ⅰ24 has N and S pole magnetism respectively, which is used to stretch the fish cover when approaching the telescopic fish cover and trap the fish therein. After the polymer brush 23 is energized, the volume changes to discharge water outward, and a low-pressure area appears in the adsorption cavity, producing an adsorption effect. A plurality of annular grooves are provided on the outer side of the groove of the fish suction plate 21 to increase the contact area between the fish suction plate 21 and the belly of the fish.

[0050] The principle is: after the base 1 of the fish swimming channel and the top cover 2 of the fish swimming channel are closed, a full-circle swimming channel is formed between the fishing box and the fish swimming channel. At this time, the fish selection door 4 is opened, and the intelligent fishing attracts the fish to the vicinity through the capture and attracting fish lights 5 arranged on it. With the help of the underwater camera 3, the telescopic fish cover 8 coordinates with the fish suction plate to force the fish to the wall of the box, and the strong fish suction plate 7 is pressed onto the body of the fish, and the fish of suitable size are selected and captured to enter the swimming channel of the energy capture device. The catching process includes: after the fish swims into the fishing box, the fish screening door 4 is closed, and when the fish is located between the telescopic fish cover 8 and the fish suction plate, the memory telescopic sheet 6 is controlled to extend through the temperature control component, and the memory telescopic sheet 6 drives the fish suction plate to approach the telescopic fish cover 8 until the magnetic steel pair II 27 on the telescopic fish cover 8 is adsorbed onto the magnetic steel pair I 24, and then the memory telescopic sheet 6 drives the fish suction plate 7 to continue to extend, and the fish suction plate 7 is pressed tightly onto the belly of the fish, and the polymer brush 23 is controlled to be energized through the intelligent integrated controller 18, and the fish suction plate 7 generates suction to suck the fish tightly, and then the memory telescopic sheet 6 is controlled to retract through the temperature control component until the magnetic steel pair II 27 is separated from the magnetic steel pair I 24, and the magnetic steel pair II 27 is re-adsorbed onto the fish screening door 4; afterwards, as the fish swims, since the strong fish suction plate 7 is fixedly installed with a duct-type follower hydro-turbine generator 9, the follower hydro-turbine generator 9 rotates and generates electricity under the impact of the water flow. The follow-up hydro-turbine generator 9 is connected to the drag generator rotor 19 arranged at the axis of the annular flow channel through the conductor tow rope 10. The conductor of the conductor tow rope 10 can transmit electricity and also has the ability of line transmission. The conductor is a soft conductor, which can meet the free swimming of the fish. The conductor pulls the drag generator rotor 19 to rotate, which not only realizes that the fish drives the outer rotor generator to generate electricity, but also transmits the electricity generated by the follow-up hydro-turbine generator 9 to the inner coil of the drag generator rotor 19 as an excitation current, and finally indirectly converts electrical energy; and a number of fish tail energy collectors 12 are arranged along the wall of the flow channel for the flowing fish, which further utilizes the energy of the water flow driven by the fish when swimming to generate electricity. The device of the present invention can fully utilize the swimming energy of the fish, and can continuously update the energy-capturing fish, and can perform long-term energy capture. The device can be fixed to the fuselage of the aircraft, operation robot, etc., to realize its self-power supply for long-term deep-sea missions.
