Description

Technical Field

[0001] This utility model relates to the field of offshore power generation technology, specifically a floating wind power and wave energy power generation device. Background Technology

[0002] A floating wind and wave power generation device is a new type of marine energy development device that integrates wind power and wave power generation technologies. It typically consists of a floating platform, a wind turbine, a wave power generation device, and related mooring and anchoring systems. The device can float at sea and be stabilized by the mooring and anchoring systems, while generating electricity using wind and wave power.

[0003] In existing technologies, wave energy generation devices come in various types, including oscillating float type, pendulum type, and raft type. Among them, the oscillating float type directly absorbs energy from the waves through the heave motion of the float and converts it into mechanical energy or electrical energy. Since the waves are in direct contact with the float, the energy conversion efficiency is relatively high, so it is widely used. However, in actual use, it is affected by different weather and environment. When the wind and waves are large, the float swings more in the vertical direction, which can easily cause collisions at both ends of the supporting structure, wasting some wave energy and causing instability of the structure. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a floating wind power and wave power generation device, which has the advantage that the support structure can move with the float, and solves the problem that the float is prone to hitting the support structure in the case of large wind and waves in the existing technology.

[0005] (II) Technical Solution: To achieve the goal of enabling the above-mentioned support structure to move together with the float, this utility model provides the following technical solution: A floating wind power and wave energy generation device, including a floating platform and an oscillating float, wherein the oscillating float is connected to a PTO system, and floating structures are provided at both the upper and lower ends of the floating platform, the number of which is not less than six, with the positions of two floating structures in the upper and lower directions corresponding to each other, and a connecting rod provided in the middle, wherein the oscillating float is sleeved on the outer circumference of the connecting rod; the floating structures are all sleeved inside a limiting frame, and the floating structures can move vertically inside the limiting frame, the limiting frame is fixedly connected to the floating platform, and the oscillating float can pass through the limiting frame.

[0006] Preferably, a limiting block is provided on the upper surface of the floating structure located at the upper end, and a limiting block is provided on the lower surface of the floating structure located at the lower end.

[0007] Preferably, the limiting block and the floating structure are integrally machined.

[0008] Preferably, the outer surface of the floating structure is provided with a groove, and the inner surface of the limiting frame is provided with a protrusion corresponding to the groove.

[0009] Preferably, the floating platform has an overall equilateral triangle structure, and each vertex of the floating platform is provided with a floating structure.

[0010] Preferably, the floating platform includes a wind power generation structure.

[0011] Preferably, the upper and lower ends of the connecting rod are provided with threads, and the connection between the connecting rod and the floating structure is threaded.

[0012] (III) Beneficial Effects: Compared with the prior art, this utility model provides a floating wind power and wave energy generation device, which has the following beneficial effects:

[0013] 1. This floating wind and wave power generation device connects the two ends of the connecting rod of the limiting oscillating float to the floating structure. This allows the floating structure to move with the oscillating float in accordance with wave changes without affecting its movement. When the oscillating float moves upward or downward under the influence of strong winds and waves, the floating structure can flexibly adjust its position according to the wave's undulations, moving in tandem with the oscillating float. Furthermore, the rigid connection between the floating structure and the connecting rod, along with the moving rod, lengthens the relative path of the oscillating float above or below. Compared to existing technologies, the oscillating float in this invention will not collide with the floating platform under extreme weather conditions, increasing the durability of both the platform and the oscillating float, and ensuring the long-term stable operation of the entire power generation device in complex and ever-changing marine environments.

[0014] 2. This floating wind and wave power generation device achieves the independence of the oscillating float during its movement by fixing a limiting frame to the floating platform and ensuring that the oscillating float can pass through the limiting frame when moving vertically. This prevents the oscillating float from being affected by the floating platform during its movement. Furthermore, matching protrusions and grooves are provided between the limiting frame and the floating structure. A limiting block is provided on the upper surface of the floating structure at the upper end, and a limiting block is provided on the lower surface of the floating structure at the lower end. This design not only ensures that the floating structure can move smoothly along the preset track inside the limiting frame, but also effectively prevents structural displacement or derailment caused by extreme marine environments (such as strong winds and waves), greatly improving the structural stability and operational safety of the entire power generation device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4A floating wind and wave energy generation device includes a floating platform 1 and an oscillating float 2. The oscillating float 2 is connected to a PTO system, which converts the mechanical energy of waves into electrical energy through a wave energy converter, such as a ring-shaped wave energy converter. The floating platform 1 has floating structures 3 at both its upper and lower ends, enabling it to float on the sea surface. There are at least six floating structures 3, specifically ten in this embodiment. Two floating structures 3 are positioned vertically opposite each other, and a connecting rod 4 is provided between them. In this embodiment, the connecting rod 4 has threads at both ends, connecting it to the floating structure 3. In practical use, a rigid connection can also be achieved by welding. The oscillating float 2 is fitted onto the outer circumference of the connecting rod 4, and the oscillating float 2 moves up and down along the outer surface of the connecting rod 4 under the action of waves. Each of the floating structures 3 is fitted inside a limiting frame 11, which limits the horizontal movement of the floating structures 3. The floating structure 3, located inside the limiting frame 11, can move vertically with the undulations of waves. The limiting frame 11 is fixedly connected to the floating platform 1. In this embodiment, the limiting frame 11 and the floating platform 1 are integrally machined structures. The oscillating float 2 can pass through the limiting frame 11. When the oscillating float 2 moves upward or downward under the influence of strong winds and waves, the floating structure 3 can flexibly adjust its position with the undulations of the waves and move in coordination with the oscillating float 2. In addition, the floating structure 3 is rigidly connected to the connecting rod 4, and moves together with the connecting rod 4, which makes the relative path of the oscillating float 2 above or below longer. At the same time, the oscillating float 2 can pass through the limiting frame 11, so that the oscillating float 2 is not affected by the floating platform 1 when it moves. Compared with the prior art, the oscillating float 2 in this utility model will not collide with the floating platform 1 under extreme weather conditions, which increases the durability of the platform and the oscillating float 2 and ensures that the entire power generation device can operate stably for a long time in a complex and changeable marine environment.

[0022] In this embodiment, please refer to Figure 2 and Figure 3 The limiting block 31 and the floating structure 3 are integrally machined structures; the outer surface of the floating structure 3 along its edge is provided with a groove 32, and the inner surface of the limiting frame 11 is provided with a protrusion 111 corresponding to the groove 32; the upper surface of the floating structure 3 at the upper end is provided with a limiting block 31, and the lower surface of the floating structure 3 at the lower end is provided with a limiting block 31; this design not only ensures that the floating structure 3 can move smoothly along the preset track inside the limiting frame 11, but also effectively prevents structural displacement or derailment caused by extreme marine environments such as strong winds and waves, greatly improving the structural stability and operational safety of the entire power generation device.

[0023] Please see Figure 1 and Figure 2The floating platform 1 has an overall equilateral triangle structure to ensure the stability of the structure. Each vertex of the floating platform 1 is equipped with a floating structure 3. The floating platform 1 includes a wind power generation structure 12, which integrates wind power generation and wave power generation. By taking advantage of the platform floating on the sea surface, the utilization rate of ocean energy is maximized and the work efficiency is improved.

[0024] Working principle: When the oscillating float 2 moves upward or downward under the influence of strong winds and waves, the floating structure 3 can flexibly adjust its position with the rise and fall of the waves and move in coordination with the oscillating float 2. At the same time, the floating structure 3 and the connecting rod 4 are rigidly connected, and the connecting rod 4 moves together, which makes the relative path of the oscillating float 2 above or below longer. In addition, the limiting frame 11 used to limit the movement track of the floating structure 3 is large, which can ensure the passage of the oscillating float 2. Thus, the independence of the oscillating float 2 in the process of movement is realized, so that the oscillating float 2 is not affected by the floating platform 1 when it moves and will not collide with the floating platform 1.

[0025] In summary, this floating wind and wave power generation device increases the durability of the platform and the oscillating float 2, ensuring that the entire power generation device can operate stably for a long time in complex and ever-changing marine environments; moreover, it effectively prevents structural displacement or derailment caused by extreme marine environments such as strong winds and waves, greatly improving the structural stability and operational safety of the entire power generation device.
