Description

Technical Field

[0001] The utility model relates to the technical field of ocean current power generation, in particular to a movable charging device for omnidirectional underwater ocean current energy collection. Background Art

[0002] In submarine channels and straits, geographical factors such as tides or monsoons cause seawater to flow regularly. Therefore, the flowing seawater generates kinetic energy, which has the advantages of high energy density, strong predictability, stable load, and rich reserves. Compared with wave energy on the sea surface, it is more stable. When the sea current speed is greater than 1 m / s, it has the value of development and utilization. It has currently become one of the key points for the development and utilization of marine renewable energy at home and abroad. However, due to the influence of factors such as temperature, climate, and salinity on underwater ocean currents, the flow direction has the characteristics of non-periodic and random changes. In addition, currently, equipment such as unmanned underwater vehicles, underwater sonars, underwater buoys, and environmental monitoring sensors that have been lurking underwater for a long time rely on replaceable lithium batteries to provide electrical energy for their long-term operation. And according to the mission requirements, they need to carry out mobile detection work underwater. Facing scenarios where traditional solar energy is difficult to cover, management agencies need to regularly salvage underwater equipment or perform underwater operations to replace the batteries, consuming a large amount of manpower and material resources. Therefore, it is extremely urgent to solve the problem of self-power supply for underwater small equipment during underwater movement.

[0003] The Chinese invention patent with the publication number of CN110925127A discloses a new type of water current generator, which includes a cylindrical protective cover and a water current generator set composed of one or more water current generators located inside the protective cover. The protective cover is fixedly connected to the water current generator. The water inlet end of the protective cover is provided with a horn pipe for collecting water current. The small end of the horn pipe is fixedly connected to the protective cover, and the large end is provided with a filter screen fixedly connected thereto. The present invention collects ocean currents through the horn pipe, accelerates the ocean currents, and then guides them to the water current generator, which can drive a water current generator with a larger capacity and generate more electrical energy.

[0004] In this solution, the power generation device can only generate electricity when the ocean current direction is horizontal and the ocean current flows towards the horn pipe. When the ocean current is inclined or perpendicular to the horn pipe, the power generation device is likely to only be able to move translationally without rotating, resulting in failure, and it cannot follow small equipment to complete mobile charging.

[0005] The Chinese utility model patent with the publication number of CN219643776U discloses a spherical eccentric multi-directional energy collection device, which 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 scenarios where ocean currents are used for power generation. Therefore, a supporting structure for protecting and carrying the internal power generation device needs to be designed. Summary of the Utility Model

[0006] In view of the deficiencies in the above-mentioned background art, the present utility model proposes a movable charging device for omnidirectional underwater ocean current energy collection, which solves the problem that the existing ocean current power generation devices cannot adapt to the multi-directionally changing ocean current environment and flexibly move to supply power to equipment.

[0007] The technical solution of the present utility model is realized as follows: A movable charging device for omnidirectional underwater ocean current energy collection includes a spherical housing. A power generation module is provided inside the spherical housing. The power generation module is connected to a transmission line, and the end of the transmission line passes through the spherical housing. A first blade group and a second blade group are provided on the outer side wall of the spherical housing, and the axes of the first blade group and the second blade group are perpendicular.

[0010] Preferably, the spherical housing includes two hemispherical shells arranged in a snap-fit manner, and the two hemispherical shells are connected by bolts. A sealing gasket is provided between the mating surfaces of the two hemispherical shells.

[0011] Preferably, through holes for the transmission line to pass through are correspondingly provided on one of the disc seats and the connected hemispherical shell. A rotary joint for satisfying rotational movement is provided on the transmission line, and the fixed end of the rotary joint is fixedly arranged at the through hole of the disc seat.

[0012] Preferably, a flange is fixedly provided on the rotating end of the rotary joint, and a fixing block is provided on the flange. The fixing block is connected to a connecting rope. The connecting rope is a steel wire rope.

[0013] Advantages of the present utility model: By providing a spherical housing, protection and waterproof capabilities can be provided for the internal power generation module; by providing a first blade group and a second blade group with perpendicular axes, under the action of ocean currents in any direction, on the side where the outer normal direction of the blade group is consistent with the water flow direction, a larger rotational torque is generated in one of the blade groups, while the rotational torque of the other blade group is smaller.

This device can be flexibly arranged around the device to be charged, omnidirectionally collect the kinetic energy of nearby ocean currents, and provide electrical energy for underwater electrical equipment in real time without human presence. The manager can recycle or move the device according to needs, configure it in a new environment, and supplement electrical energy for other devices, with high flexibility.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some 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.

[0020] Such as Figure 1 、 2, as shown in FIGS. 3, Embodiment 1, a movable charging device for omnidirectional ocean current energy collection underwater, includes a spherical housing 1. Inside the spherical housing 1, there is a power generation module, which is connected to a power transmission line 2 and the end of the power transmission line 2 passes through the spherical housing 1. The spherical housing 1 can provide protection and waterproof ability for the internal power generation module. In this embodiment, the spherical housing 1 includes two hemispherical shells arranged in a snap-fit manner, and the two hemispherical shells are connected by bolts. A sealing gasket is provided between the mating surfaces of the two hemispherical shells to play a sealing role. On the outer side wall of the spherical housing 1, there are a first blade group 3 and a second blade group 4, and the axes of the first blade group 3 and the second blade group 4 are perpendicular. By setting the first blade group 3 and the second blade group 4 with perpendicular axes, under the action of ocean currents in any direction, the blade group on the side where the outer normal direction of the blade group is consistent with the water flow direction generates a larger rotational torque, while the rotational torque of the blade group on the other side is smaller. The energy collection device can generate an unstable state and produce a reciprocating rotation effect, driving the internal power generation module to generate attitude changes and generate electricity.

[0021] Specifically, in this embodiment, both the first blade group 3 and the second blade group 4 include a pair of disc seats 5 respectively arranged at both ends of the spherical housing 1, and the disc seats 5 are connected to the spherical housing 1 by bolts. And the axes of the disc seats 5 of the first blade group 3 and the second blade group 4 are perpendicular, and a plurality of blades 6 are connected between each pair of disc seats 5. Specifically, as an implementation manner, in this embodiment, one pair of disc seats is correspondingly arranged at the outer shell vertex positions of the two hemispherical shells, and the other pair of disc seats is correspondingly arranged at the joint of the two hemispherical shells. Each disc seat is respectively connected to the two hemispherical shells by bolts.

[0022] As a further implementation manner, the blade 6 is a torsion body. In this embodiment, both the first blade group 3 and the second blade group 4 include 5 to 10 blades. The blades are coaxially and equally angularly arranged relative to the disc seats 5. The two ends of the blades are fixed to the side walls of the two disc seats, and the inner side of the blade 6 is attached to the spherical housing 1.

[0023] In this embodiment, as Figure 3 shown, the power generation module adopts a spherical eccentric multi-directional energy collection device in a Chinese utility model patent with the existing publication number CN219643776U, or an omnidirectional electromagnetic mechanical energy collection device in an invention patent with the publication number CN116404846A, or an omnidirectional multi-layer electromagnetic energy collection device in a utility model patent with the publication number CN219499189U and is placed inside the spherical housing 1. With this design of setting blades on the spherical housing, the device can effectively capture and convert energy in the marine environment, realizing flexible movement and continuous energy supply. And this device can play a good protective role, and at the same time can isolate the water body to avoid problems such as corrosion and liquid ingress. At the same time, it can also make full use of the water flow power to transfer to the internal power generation module, with a simple structure, reliable and durable, and strong economy.

[0024] This device can be flexibly set in the water body around the device to be charged. When impacted by water flow, it can omnidirectionally collect the kinetic energy of nearby ocean currents and provide electrical energy to underwater electrical devices in real time without human presence. The manager can recycle or move the device according to needs and configure it in a new environment to supplement electrical energy for other devices, with high flexibility and applicability.

[0025] Embodiment 2: On the basis of Embodiment 1, through holes for the power transmission line 2 to pass through are correspondingly provided on one of the disc seats 5 and the connected hemispherical shell. A rotary joint 8 for accommodating rotational movement is provided on the power transmission line 2, and the fixed end of the rotary joint 8 is fixedly arranged at the through hole of the disc seat 5. In this embodiment, the through hole is arranged at the axis of one of the hemispherical shells. A sealant is provided between the rotary joint 8 and the through hole. The sealant can play a sealing role to prevent water flow from entering the interior of the spherical shell through the through hole. When the internal power generation module rotates, flips or moves due to the impact of water flow on the first blade group 3 and / or the second blade group 4 on the spherical shell, electrical energy is generated by the power generation module and is output to the power consumption end through the power transmission line and the rotary joint. The rotary joint can accommodate the rotation of the spherical shell and avoid the winding of the power transmission line.

[0026] As a further implementation manner, a flange plate 7 is fixedly arranged on the rotating end of the rotary joint 8, and a fixing block 9 is arranged on the flange plate 7. The fixing block 9 is connected to a connecting rope 10. In this embodiment, the connecting rope 10 is a steel wire rope. The connecting rope can play a traction role. During use, one end of the connecting rope is connected to the fixing block, and the other end is tied to a fixed foundation to fix the position of the entire device, prevent it from being washed away by ocean currents, and at the same time avoid the long-term load-bearing stress of the power transmission line during the power generation process impacted by ocean currents, causing damage.

[0027] 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 within the protection scope of the present invention.
