Description

Technical Field

[0001] The utility model relates to the technical field of ocean current power generation, in particular to an ocean universal array power generation device. Background Art

[0002] Ocean current power generation is a technology that utilizes the kinetic energy of constant or periodically flowing ocean currents in the ocean to generate electricity. With the continuous growth of global energy demand and the increasing demand for renewable energy, ocean current power generation technology has become an important research direction in the field of renewable energy. Its main advantage is that ocean currents are relatively stable, capable of providing continuous and reliable energy output. Traditional ocean power generation methods can only utilize wave energy for power generation or utilize the temperature difference energy based on phase change materials, and cannot fully utilize the energy brought by ocean currents below the sea surface.

[0003] For example, the Chinese invention patent with the publication number CN112360672A discloses an ocean current power generation device. By utilizing ocean currents for power generation, it can effectively improve the functional diversity of the device, increase the operating speed of the device, effectively increase the power generation amount, improve the energy absorption rate, and at the same time, the device can effectively divert ocean currents, reduce the reverse blocking force of the device on ocean currents, facilitate the smooth entry of ocean currents into the device, improve the absorption effect of ocean current kinetic energy, improve the operating efficiency of the device, and improve the practicability and reliability; it includes a power cylinder, a flow concentrating hopper, a lower support ring, three groups of support rods, three groups of anchor feet, and a fixing plate. The flow concentrating hopper is installed on the left side of the power cylinder, and a secondary energy absorption device is communicated with the right side of the power cylinder. The lower support ring is located below the power cylinder, and the lower support ring is fixed on the power cylinder and the secondary energy absorption device respectively through three groups of support rods. The three groups of anchor feet are evenly installed at the bottom of the lower support ring.

[0004] However, this solution cannot meet the power generation utilization of ocean currents at different depth layers, and at the same time, it can only utilize ocean currents in a fixed direction for power generation, and is not applicable in the ocean where ocean currents are unstable.

[0005] The Chinese utility model patent with the publication number CN219643776U discloses a spherical eccentric multi-directional energy collection device. This device can convert external mechanical motion into the rotation of an eccentric rotor, thereby collecting energy from all directions in the environment and continuously powering sensors or other devices, avoiding the use of external power supplies. However, its structure lacks external protection and is difficult to be directly applied to the scenario of using ocean currents to generate electricity. Therefore, a supporting structure for protecting and carrying the internal power generation device needs to be designed. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As shown in Figure 1 and 3 Embodiment 1, a marine universal array power generation device includes a base 1. A plurality of telescopic rods 2 are provided at the bottom of the base 1. In this embodiment, the plurality of telescopic rods are arranged in an array state. A cable is provided on the telescopic rod 2, and the cable is connected to a rotary joint 3 at the telescopic end of the telescopic rod 2. The rotary joint 3 is arranged on a spherical shell 4. A blade assembly 5 and a counterweight assembly 6 are provided on the outer wall of the spherical shell 4. A power generation module 7 connected to the cable is provided inside the spherical shell 4. The spherical shell can protect the internal power generation module, playing a role in waterproofing and support. Specifically, the spherical shell 4 in this embodiment includes two hemispherical shells 8 that are buckled with each other. The power generation module 7 is arranged inside the spherical shell formed by the two hemispherical shells 8. The rotary joint is arranged at the center of one of the hemispherical shells. The rotary joint can ensure that the power generated by the power generation module during the rotational movement of the spherical shell can be stably transmitted to the cable, and at the same time can avoid the cable being wound due to rotation.

[0025] In this embodiment, the power generation module 7 adopts a spherical eccentric multi-directional energy harvesting device in a Chinese utility model patent with the existing publication number CN219643776U, an omnidirectional electromagnetic mechanical energy harvesting device in an invention patent with the publication number CN116404846A, or an omnidirectional multi-layer electromagnetic energy harvesting device in a utility model patent with the publication number CN219499189U and places them between the two hemispherical shells 8. With the design of setting blades on the spherical shell, the device can effectively capture and convert energy in the marine environment, realizing continuous energy supply. And this device can play a good protective role, and at the same time can isolate the water body, avoiding problems such as corrosion and liquid ingress. At the same time, it can also make full use of the water flow power to transmit to the internal power generation device. It has a simple structure, is reliable and durable, and has strong economy.

[0026] As a further implementation manner, as shown in Figure 4 a plurality of connection holes Ⅰ9 are provided on both of the two hemispherical shells 8 and are fixedly connected by bolts passing through the connection holes Ⅰ9. The connection holes Ⅰ9 are arranged at equal intervals along the circumferential direction of the hemispherical shell 8, and a gasket or sealing ring is provided between the opposite surfaces of the two hemispherical shells, so as to play a better sealing role.

[0027] As a further embodiment, the base 1 includes a plate electrode 17. The telescopic rod 2 is fixedly arranged at the bottom of the plate electrode 17. An energy storage unit is arranged on the plate electrode 17. The upper end of the cable is connected to the energy storage unit. The energy storage unit adopts a conventional battery and a battery circuit board. The electric energy generated by multiple power generation modules is transmitted to the battery circuit board through the cable, and the battery is charged and stored after being regulated and controlled by the battery circuit board.

[0028] When this embodiment is in use, first, according to the set ocean current depth, set the corresponding number of counterweight components so that the spherical shell can be suspended in the ocean current at the corresponding depth layer in a suspended state. Subsequently, adjust the telescopic length of the telescopic rod to control the vertical position of the spherical shell connected to its telescopic end so that it is in the ocean current at the set depth layer. Under the action of the counterweight components, the suspended posture of the spherical shell is maintained. Under the action of the ocean current impacting the blade assembly, the spherical shell is driven to rotate, thereby driving the internal power generation module to move to achieve the power generation purpose. When this implementation is in use, the length of different telescopic rods 2 can also be adjusted according to the actual distribution range of the ocean current so that the spherical shells connected to different telescopic rods are located in the ocean currents at different depth layers for power generation.

[0029] In addition, during actual use, this device can be attached to fixed marine devices such as lighthouses and buoys to generate electricity underwater and stably supply energy to the marine devices. Secondly, compared with a single universal power generation device, the energy of different ocean current layers can be effectively collected through an array setting method to collect more energy, thereby improving the utilization rate of ocean currents. Furthermore, the collected electric energy can be stored through the energy storage unit for convenient use at any time.

[0030] Embodiment 2: On the basis of Embodiment 1, the counterweight component 6 includes mounting grooves equally spacedly arranged in the circumferential direction of the hemispherical shell 8, and counterweight blocks 10 are arranged on the mounting grooves. In this embodiment, the counterweight blocks are made of lead blocks. During actual use, according to the ocean current depth at the set position, install the corresponding number of counterweight blocks in the mounting grooves, and adjust the suspended depth through the weights of different counterweight blocks, thereby achieving an array form at different height layers in the water. As an alternative solution, the mounting grooves can be optionally arranged only on one of the hemispherical shells or on both hemispherical shells.

[0031] As a further embodiment, such as Figure 4 、 5As shown in the figure, the hemispherical shell 8 is circumferentially provided with connecting holes II 11. The connecting holes II 11 on the two hemispherical shells 8 are arranged in pairs and staggered from each other. The blade assembly 5 is respectively connected to the hemispherical shell 8 through the connecting holes II 11. Specifically, the blade assembly 5 includes a plurality of arc-shaped blades 12. The arc-shaped blades 12 are provided with connecting parts 13. The connecting parts 13 of each arc-shaped blade 12 are respectively connected to each pair of connecting holes II 11 on the two hemispherical shells 8 through bolts. In this embodiment, the connecting holes and the installation grooves are arranged alternately. The staggering of the connecting holes II 11 on the two hemispherical shells 8 enables the connecting parts of the arc-shaped blades to be presented and fixed in an inclined form when connected to the two hemispherical shells, realizing a larger impact area for receiving water. As a further implementation manner, a reinforcing plate 20 is arranged outside the connecting part 13, so that the bolt sequentially passes through the reinforcing plate 20, the connecting part 13 and the connecting hole II 11 for connection, thereby achieving the purpose of reinforcing the connection of the connecting part.

[0032] Embodiment 3. On the basis of Embodiment 2, the rotary joint 3 includes a conventional rotary conductive slip ring. A through hole is arranged at the axis of the hemispherical shell. The fixed end 14 of the rotary conductive slip ring is fixedly arranged on the through hole at the axis of the hemispherical shell 8, and the rotating end 15 is connected to the cable. Moreover, the fixed end 14 of the rotary conductive slip ring is connected to the power generation module 7, so that the electric energy generated by the power generation module is transmitted to the cable through the rotary conductive slip ring for output use. In addition, for the purpose of waterproofing, a sealing glue is arranged between the fixed end of the rotary conductive slip ring and the hemispherical shell.

[0033] Embodiment 4. On the basis of Embodiment 3, as Figure 2 shown in the figure, the telescopic rod 2 includes at least two sections of pipe bodies. The cable is arranged inside the pipe bodies. The upper pipe body is fixedly connected to the base 1, and the lower pipe body is provided with an elbow 16. Moreover, the lower end of the cable passes out from the elbow 16. The cable plays a role in connecting between the rotary joint and the elbow. The upper end of the cable is connected to the energy storage unit arranged on the electrode plate for power supply.

[0034] As an optional implementation manner, the elbow and the pipe body are rotationally matched. When the ocean current direction changes, the elbow can be driven to rotate to adapt to the ocean current direction.

[0035] As a further implementation manner, a locking nut is cooperatively arranged between adjacent pipe bodies. The locking nut is threadedly connected to the outer pipe body. When locking the position between the two pipe bodies to lock the length of the long telescopic rod, rotate the locking nut. The locking nut penetrates into the outer pipe body and abuts against the side wall of the inner pipe body to realize the locking of the positions of the two pipe bodies.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
