Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, in particular to an underwater carrying device based on a power generation device. Background Art

[0002] The development of marine energy is of great significance for alleviating national energy pressure, supporting economic development, safeguarding marine rights and interests, and promoting the development of strategic industries. In particular, ocean current energy has attracted attention for its huge reserves, strong renewability and environmental friendliness. Nevertheless, due to the high cost of marine energy development, complex technical requirements, and its dispersion and low energy density, its actual development and utilization are limited. Therefore, effectively utilizing marine energy and responding to related challenges have become important tasks at present. Traditional marine energy conversion methods mainly rely on renewable resources such as tidal energy, temperature difference energy and wave energy. The current technology for applying marine energy conversion usually has the problem of large size. Although it can provide stable energy output, it lacks flexibility and must be deployed in a specific marine environment to ensure operational efficiency, which limits its wide application in different sea areas.

[0003] Based on this, a Chinese invention patent with publication number CN114109708A discloses a universal swinging power generation device under complex incoming flow, wherein a lifting arm is installed on the top surface of the spherical shell, and the lower part is connected to a flexible sealing cover to form an inner cavity, wherein an electromagnetic coil frame, a universal ball, and a sliding part are respectively placed in the inner cavity, wherein the upper part of the electromagnetic coil frame is connected to the inner top surface of the spherical shell, and the universal ball cover is arranged on the outside of the electromagnetic coil frame, one end of the piston connecting rod vertically penetrates from the bottom of the flexible sealing cover and is connected to the bottom surface of the universal ball, and the other end of the piston connecting rod is connected to the swinging oscillation mechanism, and a plurality of sliding parts are installed on the outer circumference of the universal ball, and the sliding parts are in contact with the inner circumference of the spherical shell, a plurality of electromagnetic coils are arranged on the outer circumference of the electromagnetic coil frame, and a plurality of permanent magnet blocks are correspondingly arranged on the inner circumference of the universal ball.

[0004] The device is suitable for installation on offshore platforms, wind power piles or large cruise ships. However, in this solution, the supporting structure is complex, resulting in high equipment costs. At the same time, its power generation is limited, and the value generated is difficult to match the cost.

[0005] In addition, the Chinese invention patent with publication number CN116404846A discloses an omnidirectional electromagnetic mechanical energy collection device, including a base, at least two grooves are arranged on the base, an energy collector is arranged in the groove, a cover is fixedly arranged on the upper side of the groove, at least two rectifier modules are arranged inside the base, and the energy collector is connected to the rectifier module accordingly. The present invention arranges multiple energy collectors on the base, when the base is subjected to a force in any direction in the environment, the base will move under the action of the force, the permanent magnet in the energy collector will slide relative to the coil, thereby converting the mechanical energy received by the device into electrical energy, and the multi-faceted spherical base is very easy to move after being subjected to an external force, thereby improving the energy conversion efficiency.

[0006] The omnidirectional electromagnetic mechanical energy collection device has a simple structure. As the main body of the power generation device, it can convert mechanical energy into electrical energy. However, its structure lacks external protection and is difficult to be directly applied in scenarios where ocean currents are used to generate electricity. Therefore, it is necessary to design an underwater carrying device for carrying the power generation device to protect the internal power generation device. Utility Model Content

In this embodiment, the flexible connection outlet connector 3 adopts a conventional rotating conductive slip ring, and a sealant is provided between the rotating conductive slip ring and the through hole to achieve sealing and fixation between the flexible connection outlet connector 3 and the through hole. When in use, an omnidirectional electromagnetic mechanical energy collection device such as the invention patent with the existing publication number CN116404846A or an all-round multi-layer electromagnetic energy collection device in the utility model patent with the announcement number CN219499189U is placed between the upper sealed spherical shell and the lower sealed spherical shell as a power generation device, and the blades are provided on the spherical shell. This design allows the device to effectively capture and convert energy in the marine environment and achieve continuous energy supply. The device can play a very good protective role, and at the same time it can isolate the water body to avoid corrosion, liquid ingress and other problems. At the same time, it can fully utilize the water flow power to transmit to the internal power generation device. It has a simple structure, is reliable and durable, and is highly economical.

[0028] As a further embodiment, a sealing ring is provided between the upper sealing spherical shell 4 and the lower sealing spherical shell 5.

When connecting, the plug-in ring is inserted into the plug-in groove Ⅰ13 and the sealing ring is squeezed when the bolts or screws are tightened to achieve sealing.

[0029] Embodiment 2, an underwater carrying device based on a power generation device, based on embodiment 1, such as Figure 3 As shown, the connection structure includes connection slots 7 which are circumferentially evenly spaced and arranged in pairs on the upper sealing spherical shell 4 and the lower sealing spherical shell 5. The connection slots 7 on the upper sealing spherical shell 4 and the lower sealing spherical shell 5 are staggered, and each pair of connection slots 7 is connected to the blade 2 by bolts.

The L-shaped positioning portion is a protrusion provided on the upper sealing spherical shell 4 and the lower sealing spherical shell 5, which can play a role in positioning and supporting the blade base.

[0033] Embodiment 3, an underwater carrying device based on a power generation device, based on embodiment 2, such as Figure 5 As shown, the blade 2 includes an arc-shaped blade body 11, and the arc-shaped blade body 11 is connected to the plug-in portion 12. The inner side wall of the arc-shaped blade body 11 is arranged to fit the upper sealing spherical shell 4 and the lower sealing spherical shell 5, so that the connection positioning is accurate and the stability of the blade support is improved. In this embodiment, the plug-in portion is arranged to facilitate the connection and fixation, and the blade is arranged in an arc shape, which can make the blade more susceptible to the disturbance of water flow in all directions and drive the spherical shell to move. When in use, the device is placed under the sea surface, and can achieve uninterrupted rotational motion with the help of the power of the ocean current, driving the internal dodecahedron structure to generate continuous electrical energy output. In addition, the soft connection technology used in the outlet part of the device gives it the ability to move freely in the water with the change of water flow in any direction, which effectively promotes the continuous generation of electrical energy.
