Deformable Oscillating Float Wave Energy Generation Device Applicable to Ocean Probes

Abstract

The present invention provides a deformable oscillating buoy wave energy generation device applicable to ocean detectors, which relates to the fields of ocean detectors and new energy. The device includes an air storage cabin, an energy capture and power generation cabin, a main control cabin, a power cabin, a front fairing, and a rear fairing. The detector has two working modes: underwater navigation and detection, and sea surface energy capture and power generation. In the detection mode, the deformable buoy folds, and the detector performs ocean detection tasks. When the power supply of the detector is insufficient, it floats to the sea surface, the deformable buoy unfolds, and the detector automatically changes from a horizontal attitude to a vertical attitude, realizing the mode switch from navigation to power generation. In the power generation mode, the flat deformable buoy and the slender detector body form an oscillating double buoy. The present invention realizes the wave self-power supply of ocean detectors by using deformable buoys, improving the power supply level and endurance of the detectors without affecting their navigation maneuverability.

Description

Technical Field

[0001] The present invention relates to the fields of ocean detectors and new energy, and particularly to a deformable oscillating buoy wave energy power generation device applicable to ocean detectors. Background Art

[0002] Ocean detectors are important carriers for carrying out tasks such as ocean environmental monitoring, ocean scientific research, and ocean military operations. Currently, most ocean detectors are powered externally by cables or by self - carried batteries, but the length of the cables and the capacity of the batteries are limited, restricting the movement range, load level, and endurance of the detectors.

[0003] Wave energy is the ocean energy with the highest energy density, and the oscillating buoy type wave energy device has a higher power generation efficiency compared to other wave energy devices. However, since capturing wave energy requires relatively moving components, most existing wave energy oscillating buoy devices have a fixed structural form and a large size, and can only be moored in the near - shore area. Their own maneuverability is limited, making it difficult to perform tasks such as ocean exploration.

[0004] In summary, the power supply problem of ocean detectors restricts their further development. At the same time, due to the functional and scale differences between ocean detectors and oscillating buoy wave energy devices, existing designs are difficult to effectively endow the detectors with the ability to capture wave energy for power generation while ensuring their movement ability, resulting in no precedent for well - applying oscillating buoy wave energy devices to ocean detectors.

Specifically, the link component is composed of eight sets of crank - slider mechanisms with exactly the same structural dimensions in parallel. The eight sets of crank - slider mechanisms are symmetric about the detector axis; the eight sets of crank - slider mechanisms share the first slider 221. The end face of the first slider 221 is provided with an axial sealing groove, and eight hinge supports are circumferentially distributed on the first slider 221 and are respectively hinged to the connecting rods of the eight sets of crank - slider mechanisms.

[0069] In the power generation mode, the deformable float moves relative to the detector body along the axis under the excitation of waves, drives the screw nut 219 to move relative to the screw 220, thereby driving the screw 220 to rotate, and further driving the generator 210 to rotate through the coupling 212 to generate electric energy.

[0076] Working principle:

[0077] Such as Figure 4As shown in the figure, the wave self-powered ocean detector based on a deformable oscillating float has two working modes: underwater navigation and surface power generation. The core structural component is the deformable float in the energy-harvesting and power-generation section. The deformable float consists of a deployable framework composed of a folding mechanism and a flexible outer shell composed of a flexible film. Therefore, the deformable float is airtight and can change its shape between the folded state and the deployed state. The wave self-powered ocean detector usually operates in the underwater navigation mode and can perform underwater tasks such as ocean exploration and resource exploration. When the power supply is insufficient, the detector floats to the sea surface. The drive assembly in the energy-harvesting and power-generation section drives the deformable float to deploy. At the same time, the air pump in the air storage chamber pumps the pre-stored gas in the gas storage tank into the deformable float, increasing the air pressure in the power-generation section that has decreased due to the increase in the volume of the deformable float, so that the deformable float has a full shape and is conducive to energy harvesting. In addition, the deployment of the deformable float increases the overall buoyancy of the detector, making it in a positive buoyancy state. At the same time, the main control chamber adjusts the center of gravity of the detector to move backward along the axis. At this time, the buoyancy and gravity of the detector are not collinear, and the buoyancy is greater than the gravity. The detector is affected by the resultant moment of the two, and the detector rotates from the horizontal attitude to the vertical attitude and reaches a new equilibrium state, realizing the mode switch of the detector from navigation to power generation. When the detector is fully charged, the deformable float folds, and the air pump pumps the excess gas in the deformable float back, realizing the mode switch of the detector from power generation to navigation.

[0078] As Figure 5 shown in the figure, the principle of the wave self-powered ocean detector based on a deformable oscillating float for capturing wave energy to generate electricity is a double-float oscillating wave energy device. The detector body and the deployed deformable float form a double-float. The detector body is slender and the deformable float is flat. They have different motion responses under the excitation of incident waves. Due to the characteristics of structural constraints, considering the relative motion of the two in the vertical heaving motion perpendicular to the sea surface, the linear motion of the deformable float relative to the detector body is converted into the rotational motion of the screw rod relative to the detector by a ball screw mechanism, and further drives the generator to rotate. After rectification and voltage regulation, stable electric energy is charged into the storage battery carried by the detector, realizing the function of the ocean detector capturing wave energy to supply itself.

[0079] In summary, the present invention uses a connecting rod mechanism, a screw rod mechanism, etc., introduces a deformable float into the ocean detector, endows the ocean detector with the ability to capture wave energy to generate electricity and supply itself. At the same time, since the energy-harvesting body, the deformable float, can be folded, it does not affect the maneuverability of the detector in the navigation mode.
