[0001] This invention relates to the field of wind turbine technology, specifically to a modular rapid docking device for wind turbine foundations. Background Technology

[0002] With the rapid development of the wind power industry, the installation efficiency and quality of wind turbines have become key factors restricting the construction progress and operational stability of wind farms. During wind turbine installation, the docking of the tower and foundation modules is a crucial step. Current methods for docking wind turbine towers and foundation modules mainly rely on manual operation and simple positioning tools, lacking effective guidance and precise positioning mechanisms. In actual installation, due to the large size and heavy weight of the tower and foundation modules, manual operation makes it difficult to ensure the accuracy of their position during docking, leading to installation position deviations.

[0005] Preferably, in the above-mentioned case: one end of the first connecting rod and the second connecting rod are both fixed to one side of the limiting frame, and when the vertical rod is inserted into the inner side of the guide frame, it slides along the surface of the guide inclined surface and inserts into one side of the second connecting rod; The base module has a connecting groove on one side and a connecting block fixed on the other side. When the outer side of the connecting block is inserted into the inner side of the connecting groove, the base modules are in a connected state.

[0006] Preferably, the second slide is slidably connected to the inner side of the second slide groove, and a pull rod that moves through one side of the limiting frame is fixed to the top of the second slide. A second spring is sleeved on the outer side of the pull rod.

[0007] Preferably, the two ends of the second spring are respectively connected to one side of the second slide plate and the second slide groove, and a locking rod is fixed to one side of the bottom of the second slide plate.

[0008] Preferably, the outer sides of both the first and second fixing brackets are adapted to be inserted into the inner side of the limiting groove. When the locking rod is inserted into the inner side of the locking groove, the guide assembly is in the installed state. When the locking rod leaves the inner side of the locking groove, the guide assembly is in the disassembled state.

[0009] Preferably, one side of the first fixing frame is fixed to the top outer side of the base foundation module, and one side of the second fixing frame is fixed to the bottom outer side of the tower.

[0010] Preferably, as described above: a screw is provided on one side of the second flange, and the top of the second flange is connected to the first flange via the screw, with a nut threaded onto the outer side of the screw.

[0011] Preferably, the above-mentioned prompting component includes a plurality of protective covers and a first sliding plate, wherein a protrusion is fixedly fixed at the bottom of the first sliding plate and extends through one side of the bottom of the first flange, and an indicator light is fixed on the inner wall of the protective cover.

[0012] Preferably, the first flange has a plurality of first grooves inside, the outer side of the first slide plate is slidably connected to the inner side of the first groove, a pressure sensor is fixed to the top of the inner wall of the first groove, and limiting blocks located on both sides of the pressure sensor are fixed to the inner wall of the first groove.

[0013] Preferably, the pressure sensor is fitted with a first spring on its outer side, with the two ends of the first spring connected to one side of the first slide plate and the first slide groove, the bottom of the protective cover is fixed to the top of the first flange, and the output signal of the pressure sensor is connected to the input of the indicator light.

[0014] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: 1. During the docking process between the tower and the base foundation module, the vertical rod is inserted into the inside of the guide frame and slides along the guide slope, eventually inserting into one side of the second connecting rod. The guide slope plays a guiding role, enabling the vertical rod to be accurately inserted, achieving the initial positioning and guiding docking between the tower and the base foundation module. This ensures the accuracy of their positions during the connection process, improves installation efficiency and quality, and avoids structural damage or performance degradation caused by installation position deviations.

[0015] Second, when disassembly is required, pulling the lever causes the second slide plate to slide in the second slide groove, compressing the second spring and causing the locking rod to leave the inside of the locking groove. The guide assembly is in the disassembly state, making the disassembly process simple and easy, reducing the disassembly difficulty and time cost. The guide assembly and connecting assembly can be installed and used for the next fan, realizing the reuse of parts, reducing installation costs, and improving resource utilization.

[0016] Third, during the connection of the first flange and the second flange, the first slide plate is driven to slide and compress the first spring by the compression of the protrusion. When the first slide plate contacts the pressure sensor, the pressure sensor can detect the pressure signal in time and transmit it to the indicator light to make it light up. This intuitively prompts the staff that the connection of the first flange and the second flange is complete, avoiding the problem of incomplete connection caused by inaccurate human judgment and ensuring the reliability of the flange connection.

Subsequently, concrete is poured on-site to connect multiple base foundation modules 1 into a single unit.

[0024] The base foundation module 1 has a pre-embedded steel reinforcement frame inside to enhance the overall structural strength. The prefabricated base foundation module 1 is manufactured in the factory, requiring only assembly on-site. It can be operated simply by following a plug-in method, reducing the technical requirements for construction personnel, minimizing quality problems caused by insufficient construction skills, and also reducing safety risks during construction.

[0025] The guide assembly 3 includes several first connecting rods 33 and second connecting rods 35. The first connecting rods 33 and second connecting rods 35 are symmetrically distributed around the tower 2. A vertical rod 32 is fixed to one side of the top of the first connecting rod 33, and the top of the vertical rod 32 is provided with rounded corners. A guide frame 31 is fixed to one side of the bottom of the second connecting rod 35. The guide frame 31 has a guide slope 34 that gradually decreases from the outside to the inside. The vertical rod 32 at the top of the first connecting rod 33 has rounded corners, and the guide frame 31 at the bottom of the second connecting rod 35 has a guide slope 34 that decreases from the outside to the inside. When the tower 2 is lowered, the vertical rod 32 slides along the guide slope 34 to automatically correct the position deviation and ensure that the axis of the tower 2 is aligned with the axis of the base. One end of the first connecting rod 33 and the second connecting rod 35 are fixed to one side of the limiting frame 68. When the vertical rod 32 is inserted into the inner side of the guide frame 31, it slides along the surface of the guide slope 34 and inserts into one side of the second connecting rod 35. The gradient design of the top rounded corner of the vertical rod (32) and the guide slope (34) can realize automatic correction. The inclination angle of the guide slope 34 is 15°-30°. In this embodiment, the spring is made of fatigue-resistant alloy spring steel.

[0026] The connecting assembly 6 includes several first fixing frames 61, second fixing frames 63, and limiting frames 68. Each of the first fixing frames 61 and second fixing frames 63 has a locking groove 64 on one side. The limiting frame 68 has a limiting groove 66 and a second sliding groove 67 inside. The first fixing frame 61 is fixed to the top outer side of the base module 1, and the second fixing frame 63 is fixed to the outer side of the tower 2. The limiting frame 68 encloses both components through the limiting groove 66. The second sliding plate 62 slides within the second sliding groove 67, causing the locking rod 65 to insert into the locking groove 64, thus completing the installation and locking of the guide assembly 3. The second sliding plate 62 is slidably connected to the inner side of the second sliding groove 67. A pull rod 69, which movably passes through one side of the limiting frame 68, is fixed to the top of the second sliding plate 62. A second spring 610 is sleeved on the outer side of the pull rod 69.

[0027] The two ends of the second spring 610 are respectively connected to one side of the second slide plate 62 and the second slide groove 67. A locking rod 65 is fixed to one side of the bottom of the second slide plate 62. The outer sides of the first fixing bracket 61 and the second fixing bracket 63 are adapted to be inserted into the inner side of the limiting groove 66. When the locking rod 65 is inserted into the inner side of the locking groove 64, the guide assembly 3 is in the installed state. When the locking rod 65 leaves the inner side of the locking groove 64, the guide assembly 3 is in the disassembled state. One side of the first fixing bracket 61 is fixed to the top outer side of the base base module 1, and one side of the second fixing bracket 63 is fixed to the bottom outer side of the tower 2. The second spring 610 provides preload force to the locking rod 65. When the second spring 610 is in the compressed state, it provides continuous preload force to the locking rod 65 to ensure a stable locking state. Pulling the pull rod 69 can compress the second spring 610, causing the locking rod 65 to disengage from the locking groove 64, achieving quick disassembly. After disassembly, the wear condition of the guide slope 34 should be checked, and surface treatment should be performed before reuse.

[0028] The second flange 8 is provided with a screw 4 on one side. The top of the second flange 8 is connected to the first flange 7 through the screw 4. A nut is threaded on the outside of the screw 4. The first flange 7 at the bottom of the tower 2 and the second flange 8 at the top of the base module 1 are connected by the screw 4 and the nut to achieve rigid fixation. The correction accuracy of the guide slope 34 is ±2mm. The diameter of the screw hole of the first flange 7 is 3mm larger than that of the screw 4.

[0029] The prompting component 5 includes several protective covers 51 and a first sliding plate 56. A protrusion 55 is fixed at the bottom of the first sliding plate 56 and extends through one side of the bottom of the first flange 7. An indicator light 52 is fixed on the inner wall of the protective cover 51. The protrusion 55 at the bottom of the first sliding plate 56 extends through the first flange 7. When the flange nut is tightened, the protrusion 55 is compressed, which drives the first sliding plate 56 to slide upward along the first slide groove 58. Several first slide grooves 58 are opened inside the first flange 7. The outer side of the first sliding plate 56 is slidably connected to the inner side of the first slide groove 58. A pressure sensor 53 is fixed at the top of the inner wall of the first slide groove 58. Limiting blocks 54 located on both sides of the pressure sensor 53 are fixed on the inner wall of the first slide groove 58.

[0030] A first spring 59 is sleeved on the outside of the pressure sensor 53. The two ends of the first spring 59 are respectively connected to one side of the first slide plate 56 and the first slide groove 58. The bottom of the protective cover 51 is fixed to the top of the first flange 7. The output signal of the pressure sensor 53 is connected to the input of the indicator light 52. When the first slide plate 56 contacts the pressure sensor 53, the sensor triggers a signal, illuminating the indicator light 52 inside the protective cover 51, visually indicating that the connection is complete. The first spring 59 provides a reset buffer, and the limit block 54 prevents excessive compression.

[0031] When the first slide plate 56 contacts the bottom side of the pressure sensor 53, the indicator light 52 lights up, indicating that the connection of the first flange 7 and the second flange 8 is complete. When all the indicator lights 52 light up at the same time, it means that the flange connection meets the design torque requirements.

[0032] Working principle: A connecting groove 11 is opened on one side of the base module 1, and a connecting block 12 is fixed on the other side. When installing multiple base modules 1, the outer side of the connecting block 12 of one base module 1 is inserted into the inner side of the connecting groove 11 of another base module 1. The multiple base modules 1 are connected through this plugging method, thereby constructing a stable foundation structure. The base module 1 is prefabricated and assembled on site. Before connection, the outer sides of the first fixing bracket 61 and the second fixing bracket 63 are both fitted and inserted into the inner side of the limiting groove 66. Under the elastic force of the second spring 610, the second sliding plate 62 drives the locking rod 65 to insert into the inner side of the locking groove 64. At this time, the guide assembly 3 is in the installation state, and the tower 2 and the base foundation module 1 are stably connected.

[0033] During the docking process between the tower 2 and the base foundation module 1, the vertical rod 32 is first inserted into the inner side of the guide frame 31, slides along the surface of the guide slope 34, and finally inserts into one side of the second connecting rod 35. The guide slope 34 guides the vertical rod 32, enabling the vertical rod 32 to be accurately inserted, thus achieving the initial positioning and guiding docking between the tower 2 and the base foundation module 1, and ensuring the positional accuracy of the two during the connection process.

[0034] When disassembly is required, pull the lever 69 to move the second slide plate 62 to slide within the second slide groove 67, compressing the second spring 610 and causing the locking lever 65 to leave the inside of the locking groove 64, thus disassembling the guide assembly 3. At this time, the guide assembly 3 and the connecting assembly 6 can be installed and used for the next fan, reducing installation costs. The base module 1 is connected to the top of the second flange 8, the top of the first flange 7 is fixed to the tower 2, and a screw 4 is provided on one side of the second flange 8. The top of the second flange 8 is connected to the first flange 7 through the screw 4, and a nut is threaded on the outside of the screw 4 to enhance the connection strength and stability between the tower 2 and the base module 1.

[0035] During the connection of the first flange 7 and the second flange 8, as they gradually approach and fit together, the protrusion 55 is compressed, causing the first sliding plate 56 to slide upward within the first groove 58, compressing the first spring 59. When the first sliding plate 56 contacts the bottom side of the pressure sensor 53, the pressure sensor 53 detects a pressure signal and transmits it to the indicator light 52, which illuminates, thus indicating to the operator that the connection of the first flange 7 and the second flange 8 is complete. In daily use, when the indicator light 52 goes out, the operator can check whether the screw 4 and nut near the corresponding indicator light 52 are loose.

[0036] In summary, during the docking process between the tower 2 and the base foundation module 1, the vertical rod 32 is inserted into the inside of the guide frame 31 and slides along the guide slope 34, eventually inserting into one side of the second connecting rod 35. The guide slope 34 plays a guiding role, enabling the vertical rod 32 to be accurately inserted, achieving the initial positioning and guiding docking between the tower 2 and the base foundation module 1. This ensures the accuracy of their positions during the connection process, improves installation efficiency and quality, and avoids structural damage or performance degradation caused by installation position deviations.

[0037] When disassembly is required, pulling the lever 69 causes the second slide plate 62 to slide within the second slide groove 67, compressing the second spring 610 and causing the locking lever 65 to leave the inside of the locking groove 64. The guide assembly 3 is in the disassembly state, making the disassembly process simple and easy, reducing the disassembly difficulty and time cost. The guide assembly 3 and the connecting assembly 6 can be installed and used for the next fan, realizing the reuse of components, reducing installation costs, and improving resource utilization.

[0038] During the connection of the first flange 7 and the second flange 8, the first slide plate 56 is slid and the first spring 59 is compressed by the pressure of the protrusion 55. When the first slide plate 56 contacts the pressure sensor 53, the pressure sensor 53 can detect the pressure signal in time and transmit it to the indicator light 52 to make it light up. This intuitively tells the staff that the connection of the first flange 7 and the second flange 8 is complete, avoiding the problem of incomplete connection caused by inaccurate human judgment and ensuring the reliability of the flange connection.
