Description

Technical Field

[0001] This invention relates to the field of ocean energy power generation technology, and in particular to a fixing device for ocean energy power generation equipment based on a wind turbine tower. Background Technology

[0002] In recent years, offshore wind farms have formed large-scale wind turbine tower infrastructure clusters. To improve the comprehensive energy utilization efficiency per unit sea area, integrating tidal or wave energy generation equipment onto existing wind turbine towers to simultaneously capture wind and ocean energy in the same sea area has become an important technological direction in the field of ocean energy utilization.

[0003] Currently, the common practice for mounting tidal or wave power generation equipment on wind turbine towers is to use a fixed support structure connected by welding or bolts. Although this method is simple in structure and reliable in connection, once the support is installed, the working height and horizontal orientation of the power generation equipment it supports are locked, and it cannot be adaptively adjusted according to actual operating conditions.

[0004] However, the offshore operating environment is complex and ever-changing. Tidal fluctuations cause frequent changes in water levels, and under different tidal conditions, the power generation equipment needs to be positioned in the corresponding water depth range to obtain the optimal energy capture efficiency; under different inflow conditions, the power generation equipment also needs to be positioned in the corresponding orientation to obtain the optimal energy capture efficiency; when extreme sea conditions such as typhoons occur, the power generation equipment needs to be urgently raised above the water surface to avoid structural damage caused by wave impact or collision with floating objects; in addition, during routine maintenance or troubleshooting of the power generation equipment, it also needs to be raised to a safe and convenient maintenance position to reduce the difficulty of offshore operations and personnel risks.

[0005] The aforementioned multi-dimensional engineering requirements place dynamic adjustment demands on the working height and orientation of the power generation equipment. However, the existing fixed support system cannot meet these requirements. If the spatial position of the power generation equipment needs to be adjusted, it is only possible to rely on large crane vessels to carry out overall hoisting and relocation. This method is not only cumbersome in operation and has a long construction period, but also has high costs per operation, making it difficult to achieve a rapid response to sudden working conditions.

[0006] In summary, there is an urgent need to propose a fixed device for marine energy power generation equipment based on wind turbine towers, which can not only ensure reliable support for the tower, but also flexibly and conveniently adjust the working height and orientation of the mounted power generation equipment, so as to make up for the significant shortcomings of existing fixed supports in terms of environmental adaptability and operation and maintenance operability. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a fixing device for ocean energy power generation equipment based on wind turbine towers. This solves the technical problem that the existing technology of using fixed brackets to install power generation equipment on towers cannot adaptively adjust the working height and orientation of the power generation equipment according to actual working conditions.

[0008] To achieve the above-mentioned technical objectives, the present invention provides a fixing device for ocean energy power generation equipment based on a wind turbine tower, comprising: Tower body; A guiding mechanism includes at least one guide member, which is vertically arranged and fixedly connected to the tower body; At least two rotating mechanisms are arranged at intervals along a vertical direction. Each rotating mechanism includes a fixed ring, a rotating ring, and a driving assembly. The fixed ring is sleeved on the outer wall of the tower body and slidably connected to the guide member. The rotating ring is rotatably sleeved on the outer wall of the fixed ring and used to mount the power generation equipment. The driving assembly connects the fixed ring and the rotating ring and is used to drive the rotating ring to rotate around the tower body. At least two drive mechanisms are connected to each of the fixed rings respectively, for driving the fixed rings to move up and down along the guide member.

[0011] Furthermore, the fixing ring includes an intermediate body and two limiting bodies. The two limiting bodies are fixedly sleeved on the outer side wall of the intermediate body and are respectively close to the upper and lower ends of the intermediate body. The rotating ring is rotatably sleeved on the outer side wall of the intermediate body and abuts against the two limiting bodies respectively.

[0012] Furthermore, the drive assembly includes a track and at least one moving trolley. The track is a circular structure and is fitted onto the outer side wall of the tower body and is coaxially and fixedly connected to the fixed ring. The moving trolley is connected to the track and the movable ring and is used to move along the track.

[0013] Furthermore, the track is fixedly connected to the upper end face of the intermediate body, and the two limiting bodies have protruding edges that extend to the end face of the intermediate body and are used to abut against the top of the moving trolley.

[0014] Furthermore, when the mobile carts comprise at least three, each mobile cart is arranged in a circular array structure.

[0015] Furthermore, the drive assembly also includes multiple hanging rods, multiple hooks, and multiple telescopic drive components. Each hanging rod is arranged in a circular array and is fixedly connected to the inner or outer side wall of the track. The middle part of each hook is hinged to each of the moving trolleys. The fixed end of each telescopic drive component is hinged to each of the moving trolleys, and the telescopic end of each telescopic drive component is hinged to one end of each hook, for driving the hook to rotate so that the other end of the hook hooks onto or release the hanging rod.

[0016] Furthermore, the drive mechanism includes at least two ropes and at least two winches. The lower end of each rope is connected to the fixed ring, and each winch is fixedly connected to the top of the tower body or to the top of each guide member, and is fixedly connected to the upper end of each rope to wind up or unwind the ropes.

[0017] Furthermore, the guide has a channel that extends vertically, through which the rope passes.

[0018] Compared with the prior art, the beneficial effects of the present invention include: In use, power generation equipment is mounted on each rotating ring. When it is necessary to adjust the working height and orientation of the power generation equipment, by controlling each drive mechanism, each drive mechanism drives each fixed ring to move up and down along the guide, thereby driving the rotating ring to move up and down, that is, driving the power generation equipment to move up and down, thereby realizing the adjustment of the height of the power generation equipment.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] This invention provides a fixing device for ocean energy power generation equipment based on a wind turbine tower, the structure of which is as follows: Figure 1 - Figure 3 As shown, the structure includes a tower body 100, a guide mechanism 200, at least two rotating mechanisms 300, and at least two driving mechanisms 400. The guide mechanism 200 includes at least one guide member 210, which is vertically arranged and fixedly connected to the tower body 100. The rotating mechanisms 300 are spaced apart in the vertical direction. Each rotating mechanism includes a fixed ring 310, a rotating ring 320, and a driving assembly 330. The fixed ring 310 is sleeved on the outer wall of the tower body 100 and slidably connected to the guide member 210. The rotating ring 320 is rotatably sleeved on the outer wall of the fixed ring 310 and is used to mount the power generation equipment. The driving assembly 330 connects the fixed ring 310 and the rotating ring 320 and is used to drive the rotating ring 320 to rotate around the tower body 100. Each driving mechanism 400 is connected to each fixed ring 310 and is used to drive the fixed ring 310 to move up and down along the guide member 210.

[0022] In use, power generation equipment is mounted on each rotating ring 320. When it is necessary to adjust the working height and orientation of the power generation equipment, each drive mechanism 400 is operated. Each drive mechanism 400 drives each fixed ring 310 to move up and down along the guide member 210, thereby moving the rotating ring 320 up and down, and thus moving the power generation equipment up and down, to achieve the adjustment of the height of the power generation equipment. By operating the drive component 330, the drive component 330 drives the rotating ring 320 to rotate around the tower body 100, thereby moving the power generation equipment around the tower body 100, to achieve the adjustment of the orientation of the power generation equipment. This marine energy power generation equipment fixing device based on the wind turbine tower can adaptively adjust the working height and orientation of the power generation equipment according to the actual working conditions.

[0023] As a preferred embodiment, please refer to Figure 1When the guide member 210 includes at least three, each guide member 210 is distributed in a ring array structure. Each guide member 210 together constitutes a structural component surrounding the tower body 100, providing a stable lifting track 331 for the fixed ring 310, thereby making the fixed ring 310 uniformly stressed and move smoothly.

[0024] As a preferred embodiment, please refer to Figure 1 The guide component 210 is a guide rail, which is welded to the outer wall of the tower body 100.

[0025] In another embodiment, the guide member 210 is a guide rod, which is welded to the outer wall of the tower body 100.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 3 The fixed ring 310 has at least one connecting part 311, and each connecting part 311 is slidably connected to each guide member 210 in a one-to-one correspondence. Thus, the sliding connection between the connecting part 311 and the guide member 210 forms a guiding and limiting function, thereby improving the stability of the fixed ring 310 moving up and down.

[0027] As a preferred embodiment, please refer to Figure 3 When the guide member 210 is a guide rail, the connecting part 311 is a sliding groove, which slides and connects with the guide rail to form a guiding and limiting function.

[0028] As a preferred embodiment, please refer to Figure 3 The groove is formed by two protrusions, which are spaced apart in the horizontal direction, and a groove is formed between the two protrusions.

[0029] In a preferred embodiment, the groove is formed by two rollers spaced horizontally apart, forming a groove between the two rollers.

[0030] In a preferred embodiment, when the guide member 210 is a guide rod, the connecting part 311 is a sleeve hole, which is slidably connected to the guide rod through the sleeve hole to form a guiding and limiting function.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 3The fixed ring 310 includes an intermediate body 312 and two limiting bodies 313. The two limiting bodies 313 are fixedly sleeved on the outer wall of the intermediate body 312, respectively close to the upper and lower ends of the intermediate body 312. The rotating ring 320 is rotatably sleeved on the outer wall of the intermediate body 312 and abuts against the two limiting bodies 313. Thus, the two limiting bodies 313 can limit the axial movement of the rotating ring 320, preventing axial displacement. The load of the power generation equipment is simultaneously transmitted to the intermediate body 312 and the two limiting bodies 313 through the rotating ring 320, and then from the intermediate body 312 and the two limiting bodies 313 to the guide member 210 and the tower body 100, achieving multi-stage distributed load transmission. If the power generation equipment is connected to the rotating rings 320 of each rotating mechanism 300 at the same time, when the power generation equipment is subjected to water flow or wave load, the force generated is transmitted to each rotating mechanism 300 through each connection area. The load inside each rotating mechanism 300 is then distributed to the intermediate body 312 and the two limiting bodies 313 through the rotating rings 320, thus forming a multi-level force distribution system. This avoids the stress concentration problem caused by excessive force on a single structure, significantly improves the stress state of the overall structure, and enhances the reliability and safety of the device. The two limiting bodies 313 clamp and wrap the intermediate body 312 in the middle, forming a closed support surface, which effectively improves the overall stiffness and torsional performance of the fixed ring 310.

[0032] As a preferred embodiment, please refer to Figure 3 The intermediate body 312 has at least one connecting part 311.

[0033] As a preferred embodiment, please refer to Figure 3 The inner wall of the rotating ring 320 and the outer wall of the intermediate body 312 are rotatably connected via a bearing. That is, the inner ring of the bearing is fitted onto the outer wall of the intermediate body 312 and is interference-fitted with the outer wall of the intermediate body 312, and the rotating ring 320 is fitted onto the outer wall of the outer ring of the bearing and is interference-fitted with the outer wall of the outer ring of the bearing.

[0034] As a preferred embodiment, please refer to Figure 3 and Figure 5 The drive assembly 330 includes a track 331 and at least one movable trolley 332. The track 331 is a circular structure and is fitted onto the outer side wall of the tower body 100 and is coaxially fixedly connected to the fixed ring 310. The movable trolley 332 is connected to the track 331 and the movable ring and is used to move along the track 331. The movement of the movable trolley 332 along the track 331 drives the movable ring to rotate around the fixed ring 310.

[0035] As a preferred embodiment, please refer to Figure 5The track 331 is fixedly connected to the upper end face of the intermediate body 312. The two limiting bodies 313 have protruding edges 3131 that extend to the end face of the intermediate body 312 and are used to abut against the top of the moving trolley 332. This can limit the upward movement of the moving trolley 332, prevent the moving trolley 332 from jumping upward on the track 331, and improve the stability of the moving trolley 332.

[0036] In a preferred embodiment, the wheels of the mobile trolley 332 are driven by a motor and have a locking function. When the wheels of the mobile trolley 332 stop rotating, the position of the mobile trolley 332 can be locked by the friction between the wheels of the mobile trolley 332 and the track 331, so that the rotating ring 320 can be maintained in that position, and the power generation equipment can be maintained in that orientation.

[0037] As a preferred embodiment, please refer to Figure 3 When the mobile cart 332 includes at least three, each mobile cart 332 is distributed in a ring array structure, which improves the stability of the rotation of the rotating ring 320, thereby making the rotating ring 320 uniformly stressed and moving smoothly.

[0038] As a preferred embodiment, please refer to Figure 5 The drive assembly 330 also includes multiple hanging rods 333, multiple hooks (not shown in the figure), and multiple telescopic drive components (not shown in the figure). The hanging rods 333 are arranged in a ring array and are all fixedly connected to the inner or outer side wall of the track 331. The middle part of each hook is hinged to each moving trolley 332. The fixed end of each telescopic drive component is hinged to each moving trolley 332, and the telescopic end of each telescopic drive component is hinged to one end of each hook to drive the hook to rotate so that the other end of the hook hooks onto or release the hanging rod 333. When the moving trolley 332 moves to a certain position, the wheels of the moving trolley 332 stop rotating, and the telescopic drive component drives the hook to rotate so that the other end of the hook hooks downwards onto the hanging rod 333, thereby locking it with the track 331 and ensuring the stability of the orientation of the power generation equipment.

[0039] In another embodiment, the drive assembly 330 includes a transmission gear ring (not shown in the figure), a drive gear (not shown in the figure), and a rotation drive member (not shown in the figure). The transmission gear ring is rotatably sleeved on the outer wall of the fixed ring 310 and fixedly connected to the movable ring. The drive gear meshes with the transmission gear ring. The fixed end of the rotation drive member is fixedly connected to the fixed ring 310, and the output end of the rotation drive member is coaxially fixedly connected to the drive gear to drive the drive gear to rotate. When the rotation drive member is activated, the output end of the rotation drive member rotates, driving the drive gear to rotate, which in turn drives the transmission gear ring to rotate, thereby driving the movable ring to rotate, thus realizing the adjustment of the orientation of the power generation equipment mounted on the movable ring.

[0040] As a preferred embodiment, please refer to 1 and Figure 2 The rotating mechanism 300 also includes a connecting seat 340, which has a central hole and is sleeved on the outer side wall of the rotating ring 320 through the central hole. The connecting seat 340 abuts against two limiting bodies 313 respectively, and the connecting seat 340 is used to mount the power generation equipment.

[0041] As a preferred embodiment, please refer to Figure 2 The connector 340 includes two semi-ring seats, each of which has a semi-circular slot. The two semi-ring seats are detachably and fixedly connected, and can form a central hole by enclosing the two slots.

[0042] In a preferred embodiment, the two semi-ring seats are detachably fixed together by bolts.

[0043] As a preferred embodiment, please refer to Figure 2 and Figure 3 The drive mechanism 400 includes at least two ropes 410 and at least two winches 420. The lower end of each rope 410 is connected to a fixed ring 310. Each winch 420 is fixedly connected to the top of the tower body 100 or to the top of each guide member 210, and is also fixedly connected to the upper end of each rope 410 to wind up or unwind the ropes 410. When each winch 420 of the drive mechanism 400 is started simultaneously, each winch 420 winds up or unwinds each rope 410, thereby driving the fixed ring 310 to move up and down, and in turn driving the rotating ring 320 to move up and down, realizing the flexible lifting and lowering of the fixed ring 310. This is convenient to operate and also drives the power generation equipment to move up and down, realizing the adjustment of the height of the power generation equipment. By using the drive method of winches 420 and ropes 410, the up and down movement of the power generation equipment mounted on the fixed ring 310 and rotating ring 320 can be easily realized. The working height of the power generation device can be flexibly adjusted according to different tide levels and different working conditions, making it highly adaptable.

[0044] As a preferred embodiment, please refer to Figure 3 The lower ends of ropes 410 are all connected to intermediate body 312.

[0045] As a preferred embodiment, please refer to Figure 3 and Figure 4 The guide component 210 has a channel 211 that extends vertically. The rope 410 passes through the channel 211. The channel 211 can both guide the rope 410 and protect it, reducing the corrosion and interference of wind, waves and salt spray in the marine environment on the rope 410 and extending its service life.

[0046] In another embodiment, the drive mechanism 400 includes a plurality of linear motors, each of which is slidably connected to each guide member 210 and fixedly connected to the fixed ring 310. By moving each linear motor up and down along the guide member 210, the fixed ring 310 can be moved up and down, which in turn can drive the rotating ring 320 to move up and down, that is, drive the power generation equipment to move up and down, thereby realizing the adjustment of the height of the power generation equipment.

[0047] To better understand this invention, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of the present invention will be described in detail below: In use, power generation equipment is mounted on each rotating ring 320. When it is necessary to adjust the working height and orientation of the power generation equipment, each winch 420 of the drive mechanism 400 starts simultaneously. Each winch 420 winds up or unwinds each rope 410, thereby driving the fixed ring 310 to move up and down, which in turn drives the rotating ring 320 to move up and down, realizing the flexible lifting and lowering of the fixed ring 310. This is convenient to operate and also drives the power generation equipment to move up and down, realizing the adjustment of the height of the power generation equipment. At the same time, each moving trolley 332 of the drive assembly 330 moves along the track 33 1. The movement causes the movable ring 310 to rotate, which in turn causes the power generation equipment to rotate around the tower body 100, thereby adjusting the orientation of the power generation equipment. When the moving trolley 332 moves to a certain position, the wheels of the moving trolley 332 stop rotating, and the telescopic drive drives the hook to rotate, so that the other end of the hook can hook down onto the hanging rod 333, thereby locking it with the track 331 and ensuring the stability of the orientation of the power generation equipment. This marine energy power generation equipment fixing device based on the wind turbine tower can adaptively adjust the working height and orientation of the power generation equipment according to the actual working conditions.

[0048] The present invention provides a fixing device for ocean energy power generation equipment based on a wind turbine tower, which has the following beneficial effects: (1) When the trolley 332 moves to a certain position, the wheels of the trolley 332 stop rotating, and the telescopic drive drives the hook to rotate, so that the other end of the hook can hook the hanging rod 333 downward, thereby locking it with the track 331 and ensuring the stability of the orientation of the power generation equipment. (2) The power generation equipment is connected to the rotating ring 320 of each rotating mechanism 300. When the power generation equipment is subjected to water flow or wave load, the force generated is transmitted to each rotating mechanism 300 through each connection area. The load inside each rotating mechanism 300 is distributed to the intermediate body 312 and the two limiting bodies 313 through the rotating ring 320, thus forming a multi-level force distribution system. This avoids the stress concentration problem caused by excessive force on a single structure, significantly improves the stress state of the overall structure, and improves the reliability and safety of the device. (3) The fixed device for marine energy power generation equipment based on wind turbine tower can adaptably adjust the working height and orientation of the power generation equipment according to the actual working conditions.

[0049] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
