Description

Technical Field

[0001] This invention belongs to the fields of fluid machinery, wind power generation and multi-energy complementary green energy development technology. Specifically, it relates to a fluid and kinetic energy conversion power generation system based on Euler body topology that utilizes geometric topological shapes to convert multi-dimensional, non-directional, irregular swaying energy into electrical energy through an internal spatial directional closed-loop pipe. Background Technology

[0002] Energy in nature (such as ocean wave energy and wind turbulence energy), as well as the kinetic energy generated by human or animal activities and the kinetic energy from off-road vehicle vibrations, typically exhibit low-frequency, highly random, multi-directional, and irregular "directional swaying" characteristics. Traditional water turbines, wind turbines, or oscillating energy transducers can usually only respond to advection in a single direction (such as steady water flow or fixed wind direction) or simple harmonic motion with a specific degree of freedom. When faced with multi-dimensional, interwoven, irregular swaying, the energy capture efficiency of traditional equipment drops precipitously, and may even lead to structural damage due to uneven stress. Furthermore, existing equipment cannot adaptively switch and regulate between dense water media and rarefied air media.

[0003] Currently, in existing specialized underwater devices (such as a fully enclosed eutectic underwater intelligent cruise device, application number: 2026112891086), although a preliminary concept of using internal coils and magnetic blocks for auxiliary self-generation has been proposed, these prior technologies all suffer from significant hydrodynamic and electromagnetic dead zones: their internal design lacks specific guiding tracks, or they only employ traditional non-closed linear reciprocating pipes. This causes the magnetic material to frequently impact the pipe ends axially when the outer shell sways, resulting in severe mechanical fatigue and kinetic energy loss, and also exhibiting severe "motion dead points," leading to extremely low energy conversion efficiency.

[0004] Meanwhile, in traditional designs, the mutual magnetic repulsion between multiple magnets, as well as the back electromotive force and "electromagnetic braking" losses caused by Lenz's law within the continuous winding coils, result in a "dead zone" where such devices cannot start when faced with weak energy swaying such as low-speed fluids or light winds. Therefore, how to overcome the limitations at the underlying physical mechanism level and design a universal power generation system that can efficiently convert omnidirectional irregular swaying into directional continuous energy conversion, while also having ultra-low threshold start-up capabilities, is a core technical challenge that urgently needs to be solved in this field. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this invention provides a fluid and kinetic energy conversion power generation system based on Europoid topology. This invention uses a Europoid as the core energy-absorbing shape. When this shape is subjected to any external force and experiences irregular, directionless swaying, the outer shell 1 naturally generates multi-degree-of-freedom three-dimensional motion. The core innovation lies in the inclusion of a spatial closed-loop guide pipe 4 within the outer shell 1, conforming to the geometric trend of the Europoid's topological surface. Due to the irregular interlacing and torsional characteristics of the Europoid surface, this invention incorporates a spatial closed-loop guide pipe 4 within the cavity, conforming to the geometric trend of the Europoid's topological surface. Because of the irregular interlacing and torsional characteristics of the Europoid surface, the closed-loop guide pipe 4 of this invention forms a three-dimensional irregular closed track in space, with continuously changing slopes in multiple dimensions and a perpetual gravitational drop. This spatial closed-loop trajectory not only includes the energy-efficient Europoid's maximum outer edge skeleton line but also effectively protects all inwardly recessed, deformed, or internally spiraling multi-axial closed torsional curves, preventing malicious design evasion.

[0006] When the outer casing 1 shakes in any direction, the spatial orientation of the entire internal closed pipe 4 changes drastically, and no point inside the pipe can become a dead point for mechanical balance. This physically forces the single strong magnetic slider, i.e., the magnetic body 6, inside the pipe to perform high-speed, continuous, and unimpeded directional closed-loop cyclic rolling within the unobstructed spatial closed-loop guide pipe 4 under the combined force of gravity and inertia. Since only a single magnetic block is set in the system, the risk of multiple magnets getting stuck is fundamentally eliminated. By arranging physically discontinuous segmented independent coil units 7 at intervals outside the pipe 4, and each unit is equipped with an independent low-voltage drop unidirectional rectifier circuit 9 and a distributed DC bus 10, when this single magnetic body 6 is violently scouring inside the pipe, it will alternately and frequently cut off each coil unit 7. The working coils output independently, and the non-working coils automatically reverse and cut off, completely solving the problem of internal current backflow and electromagnetic braking loss caused by back electromotive force, and reducing the starting threshold to the limit.

[0007] This invention features three specialized structural modes to cope with different media environments: In the "rigid hydrodynamic model," thick-walled pressure-resistant composite materials are used to withstand high water pressure and strong water hammer impact; in the "rigid aerodynamic model," the outer shell 1 is specialized into an ultra-lightweight, ultra-thin rigid form of carbon fiber or engineering plastic (not requiring mechanical pressure resistance like underwater), and the inside of the pipe 4 is configured with a high vacuum to eliminate air resistance, reducing the cut-in wind speed threshold to an astonishing 1.2 m / s ~ 1.5 m / s, allowing it to start automatically in urban breezes; in the "vehicle-mounted adaptive variable structure mode," it is specially customized for RV off-road camping, and the internal airbags and circuits can switch freely between lightweight vehicle-mounted wind power and high-density off-vehicle stream power generation.

Detailed Implementation

[0010] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The final sequentially numbered embodiments and the logic of the drawings of the present invention will be explained in a matching manner.

[0011] like Figure 1 As shown, the core of this energy capture system relies on a 100% mechanically sealed hollow cavity structure, namely the energy-receiving shell unit 1. Universal ball hinges 3 are symmetrically arranged at both ends of its long axis, flexibly suspending it from a stationary external mounting bracket mechanism 2. When impacted by external waves, natural wind, or human / vehicle movement, the energy-receiving shell unit 1 generates a 360-degree unidirectional rotation or multi-axial reciprocating oscillation composite energy-transforming motion around its central axis in a three-dimensional flow field. To prevent environmental marine fouling, a miniature ultrasonic generator chip 5 is also built into the sealed cavity inside the energy-receiving shell unit 1, which periodically emits low-amplitude high-frequency ultrasonic waves to the shell surface for acoustic vibration and anti-fouling.

[0012] In order to capture multi-dimensional and multi-directional kinetic energy on a macroscopic level, such as Figure 1 As shown, one or more spatial closed-loop guiding pipes 4 can be arranged within the internal cavity of the energy-receiving outer shell unit 1. When multiple pipes are used, they are arranged in a spatial three-dimensional staggered pattern or in a multi-layered concentric recessed arrangement. Figure 1In the macroscopic spatial assembly, its specialization manifests as a three-dimensional staggered arrangement of a solid line and a dashed line to increase the spatial distance between the sliding magnets on each track, completely eliminating the risk of magnetic interference between multiple channels. Each pipe is configured to operate under a high vacuum. When all pipes in the system generate electricity, the electrical energy is transmitted through the interface at the universal joint system, via the distributed DC bus 10 (i.e., Figure 1 The electrical output line segment 10) is led out from the outside of the bracket to the external downstream electrical module.

[0013] like Figure 2 As shown in the structural breakdown of the single-tube transducer, each spatially closed-loop guide pipe 4 contains a single, independently housed magnetic body 6 within its vacuum. This single magnetic body 6 can preferably be a miniature, strongly polarized cylindrical magnet at both ends, a spherical strong magnetic bead, or a connected structure composed of multiple magnets linked together by flexible connectors. When the outer shell is disturbed and experiences spatial swaying in any dimension, the orientation of the pipe 4 changes drastically. Driven by a combination of gravity and inertia, the single magnetic body 6 undergoes high-speed closed-loop cyclic scouring and rolling within the vacuum track without end-point obstruction. The pipe 4 is externally encased in an induction coil assembly, composed of multiple independently spaced coil units 7. These coil units 7 are physically discontinuous, with electromagnetic buffer zones 8 completely exposed between each pair of coil units. This allows the magnetic body 6 to accelerate under gravity in a zero electromagnetic resistance region after detaching from the coil, thereby eliminating the resistance lock-up caused by Lenz's law.

[0014] like Figure 3 As shown in the block diagram of the pure electric energy flow principle, the output of each independent coil unit 7 is individually connected to a set of low-dropout unidirectional rectifier circuits 9. Subsequently, all circuits are connected in parallel bus structure to the same distributed DC bus 10. The current transmitted from the distributed DC bus 10 is first input to the supercapacitor array 11 for physical peak shaving and valley smoothing, and then input to the bidirectional BMS battery management system 12 for safe control logic balancing of charging and discharging, and finally stored in the energy storage lithium battery pack 13 with high density. The energy storage lithium battery pack 13 is connected to two parallel electric energy flow branches: the most core and robust main flow is connected to the [power output terminal] below the battery pack to release high-saturation main power for use by external large loads; while the other highly intelligent auxiliary bypass self-power consumption branch is independently connected in parallel from the side wall of the bidirectional BMS battery management system 12 to deliver weak current to the miniature ultrasonic wave generator chip 5 fixed in the corner of the cavity inside the energy receiving shell 1. A tiny portion of the low-voltage electrical circuitry, diverted from the BMS control center, sustains the ultrasonic chip 5 to emit low-amplitude, high-frequency sound waves around the clock, enabling the entire system to operate autonomously, maintenance-free, and protected against contamination. The entire system achieves a highly hierarchical and perfectly logical closed loop in terms of physical, hardware, and electrical flow.
