Description

Technical Field

[0001] This utility model relates to the field of offshore wind turbine equipment technology, and in particular to a highly stable offshore wind turbine translation and sliding mechanism. Background Technology

[0002] Offshore wind energy, as a clean and renewable energy source, plays an important role in the transformation of the energy structure, and the installation and maintenance of offshore wind turbines are becoming increasingly frequent. During the installation and maintenance of offshore wind turbines, it is often necessary to move and adjust the main body of the turbine or key components on the offshore platform or installation carrier to achieve precise alignment or relocation, which requires the reliance on translation and sliding mechanisms.

[0003] Existing offshore wind turbine translation and sliding mechanisms mostly employ a simple track and slider structure, with a drive device propelling the slider to move the turbine components along the track. However, the offshore environment is complex and harsh, with continuous wave impacts, sea wind disturbances, and platform swaying. Existing translation and sliding mechanisms have the following shortcomings:

[0004] 1. Poor stability: Under swaying conditions at sea, the slider is prone to lateral displacement or vertical jumping, which causes the wind turbine components to shake violently during the translation process. This not only affects the alignment accuracy, but may also cause collision damage to the components.

[0005] 2. Low positioning accuracy: After translation, positioning relies solely on the braking function of the drive unit. Braking gaps and sea swaying can easily cause positional deviations, failing to meet the high-precision positioning requirements during wind turbine installation and maintenance. Therefore, designing a marine wind turbine translation and sliding mechanism that can adapt to complex marine conditions, possesses high stability, strong impact resistance, and accurate positioning is crucial to solving the current challenges of marine wind turbine translation operations. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings mentioned above by proposing a highly stable offshore wind turbine translation and sliding mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A highly stable offshore wind turbine translation and sliding mechanism includes an offshore platform. A base is fixedly connected to the top of the offshore platform. A support platform for placing the wind turbine equipment is provided on the top of the base. A drive assembly, a sliding assembly, and a positioning assembly are provided between the support platform and the base. Multiple anti-slip protrusions are fixedly connected to the top of the support platform. A baffle is fixedly provided on the top edge of the support platform. The drive assembly includes a servo motor, a reducer, a drive gear, a rack fixedly connected to the top of the base, and a high-precision distance sensor fixedly connected to the top of the base.

[0009] In a preferred embodiment of this invention, the servo motor is fixedly connected to the bottom of the support platform, and two support plates are fixedly connected to the bottom of the support platform. The two support plates are rotatably connected to the same rotating shaft. The drive gear is fixedly sleeved on the outside of the rotating shaft. The reducer is fixedly connected to one side of the left support plate. The output shaft of the servo motor is fixedly connected to the input shaft of the reducer. The output shaft of the reducer is fixedly connected to one end of the rotating shaft. The drive gear meshes with a rack. An encoder is fixedly connected to one side of the servo motor.

[0010] In a preferred embodiment of this invention, a vertical plate is fixedly connected to the top of the base, and the high-precision ranging sensor is fixedly connected to the front side of the vertical plate.

[0011] As a preferred embodiment of this utility model, the sliding assembly includes two slide rails fixedly connected to the top of the base and four upper plates fixedly connected to the bottom of the support platform. The bottom of each upper plate is detachably and sequentially fixedly connected to a shock-absorbing rubber pad and a lower plate. The bottom of each lower plate is fixedly connected to two connecting plates, and the same guide wheel is rotatably connected between the two connecting plates. The guide wheel is rolled within the slide rails.

[0012] In a preferred embodiment of this invention, the shock-absorbing rubber pad is movably abutted between the upper plate and the lower plate, and the bottom of the lower plate is threaded with two upper screws. The shock-absorbing rubber pad and the lower plate are fixedly connected to the bottom of the upper plate by the two upper screws.

[0013] As a preferred embodiment of this utility model, both sides of the slide rail are provided with slide grooves, and slide rods are fixedly connected to the side of the two connecting plates that are close to each other, with the two slide rods slidingly sleeved in the corresponding slide grooves respectively.

[0014] As a preferred embodiment of the present invention, the positioning component includes multiple wide-mouth slots formed on the top of the base, and two cylinders fixedly connected to the bottom of the support platform. A positioning groove is formed on the bottom inner wall of the wide-mouth slot, and a positioning rod is fixedly connected to the output shaft of the cylinder, and the positioning rod cooperates with the positioning groove.

[0015] As a preferred embodiment of this invention, the top of the base is threaded with four screws, and the base is fixedly connected to the top of the offshore platform by the four screws.

[0016] In this utility model, a high-stability offshore wind turbine translation and sliding mechanism is described. The base is stably installed on the offshore platform using screws. The main body or key components of the offshore wind turbine to be translated are placed on the support platform. Anti-slip protrusions and baffles ensure stable placement of the components. A servo motor is started, and after being reduced in speed by a reducer, it drives the rotating shaft and drive gear to rotate. The drive gear meshes with a rack and pinion, driving the support platform slide rail to move smoothly. During this process, stable guidance is achieved through the rolling of guide wheels on the slide rail and the sliding of slide rods in the slide grooves. Simultaneously, shock-absorbing rubber pads are installed between the upper and lower plates to absorb vibrations from swaying and translation, further improving the stability during translation and sliding.

[0017] In this invention, a highly stable offshore wind turbine translation and sliding mechanism is described. Through an encoder, the speed and angle of the servo motor can be precisely controlled, thereby achieving precise adjustment of the translation speed and displacement of the support platform. At the same time, through the measurement of a high-precision distance sensor, the accuracy of the support platform's movement is further improved. When the support platform is detected to have moved to the target position, the servo motor stops running and brakes, while the cylinder starts, driving the positioning rod to move downward. Guided by the wide slot and the tip of the positioning rod, the positioning rod is precisely inserted into the positioning slot, completing the precise positioning of the support platform. After the translation operation is completed, the cylinder drives the positioning rod to be pulled out of the positioning slot, the servo motor rotates in the reverse direction, and drives the support platform to return to the initial position, waiting for the next operation.

[0018] This utility model features a reasonable structural design. Through the guiding and limiting of the sliding component, the lateral offset and vertical movement of the sliding component are effectively restricted. The shock-absorbing rubber pads can absorb the vibration and impact generated during the swaying and translation process at sea, further improving the stability of the sliding component. The setting of servo motor, encoder and high-precision distance sensor realizes the precise control of the translational displacement of the support platform. The mechanical positioning of the support platform is realized by the insertion of the positioning rod and the positioning slot. The dual positioning guarantee ensures that the support platform can accurately stop at the target position, meeting the high-precision positioning requirements in the installation and maintenance of offshore wind turbines.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A highly stable offshore wind turbine translation and sliding mechanism includes an offshore platform 1, a base 2 fixedly connected to the top of the offshore platform 1, a support platform 4 for placing the wind turbine equipment on the top of the base 2, a drive assembly 5 and a sliding assembly 6 and a positioning assembly 7 are arranged between the support platform 4 and the base 2, a plurality of anti-slip protrusions 9 are fixedly connected to the top of the support platform 4, and a baffle 8 is fixedly arranged on the top edge of the support platform 4. The drive assembly 5 includes a servo motor 53, a reducer 56, a drive gear 55 and a rack 58 fixedly connected to the top of the base 2, and a high-precision distance sensor 51 fixedly connected to the top of the base 2.

[0026] Furthermore, refer to Figures 1-4 The servo motor 53 is fixedly connected to the bottom of the support platform 4. Two support plates 57 are fixedly connected to the bottom of the support platform 4. The two support plates 57 are rotatably connected to the same rotating shaft 59. The drive gear 55 is fixedly sleeved on the outside of the rotating shaft 59. The reducer 56 is fixedly connected to one side of the left support plate 57. The output shaft of the servo motor 53 is fixedly connected to the input shaft of the reducer 56. The output shaft of the reducer 56 is fixedly connected to one end of the rotating shaft 59. The drive gear 55 meshes with the rack 58. An encoder 54 is fixedly connected to one side of the servo motor 53.

[0027] The above scheme is adopted as follows: servo motor 53 is started. After being reduced in speed by reducer 56, servo motor 53 drives shaft 59 and drive gear 55 to rotate. Drive gear 55 meshes with rack 58 to drive the carrier platform 4 to move smoothly along slide rail 61. Through encoder 54, the speed and angle of servo motor 53 can be finely controlled, thereby realizing the precise adjustment of translation speed and displacement of carrier platform 4. At the same time, through the measurement of high-precision distance sensor 51, the precise movement of carrier platform 4 is further improved. When carrier platform 4 is detected to have moved to the target position, servo motor 53 stops running and brakes.

[0028] Furthermore, a vertical plate 52 is fixedly connected to the top of the base 2, and a high-precision ranging sensor 51 is fixedly connected to the front side of the vertical plate 52, which facilitates the support and fixation of the high-precision ranging sensor 51.

[0029] Furthermore, refer to Figures 1-4 The sliding assembly 6 includes two slide rails 61 fixedly connected to the top of the base 2 and four upper plates 69 fixedly connected to the bottom of the support platform 4. The bottom of the upper plate 69 is detachably fixedly connected to a shock-absorbing rubber pad 68 and a lower plate 67. The bottom of the lower plate 67 is fixedly connected to two connecting plates 65. The two connecting plates 65 are rotatably connected to the same guide wheel 63. The guide wheel 63 is rolled in the slide rail 61. The shock-absorbing rubber pad 68 is movably abutted between the upper plate 69 and the lower plate 67. The bottom of the lower plate 67 is threaded with two upper screws 66. The shock-absorbing rubber pad 68 and the lower plate 67 are fixedly connected to the bottom of the upper plate 69 by the two upper screws 66. The slide rails 61 are provided with slide grooves 62 on both sides. The two connecting plates 65 are fixedly connected to the side that is close to each other. The two slide rods 64 are slidably sleeved in the corresponding slide grooves 62.

[0030] The above solution is adopted: during the translation and sliding process, stable guidance can be achieved by the rolling of the guide wheel 63 on the slide rail 61 and the sliding of the slide rod 64 in the slide groove 62. At the same time, a shock-absorbing rubber pad 68 is installed between the upper and lower plates to absorb the vibration of sea swaying and translation, and further improve the stability during translation and sliding.

[0031] Furthermore, refer to Figures 2-4 The positioning component 7 includes multiple wide slots 72 opened on the top of the base 2, and two cylinders 73 fixedly connected to the bottom of the support platform 4. The bottom inner wall of the wide slot 72 is provided with a positioning groove 71, and a positioning rod 74 is fixedly connected to the output shaft of the cylinder 73. The positioning rod 74 cooperates with the positioning groove 71.

[0032] Using the above scheme: When the carrier platform 4 is detected to have moved to the target position, the servo motor 53 stops running and brakes, while the cylinder 73 starts, driving the positioning rod 74 to move downward. Guided by the wide slot 72 and the tip of the positioning rod 74, the positioning rod 74 is precisely inserted into the positioning slot 71, completing the precise positioning of the carrier platform 4. After the translation operation is completed, the cylinder 73 drives the positioning rod 74 to be pulled out of the positioning slot 71, and the servo motor 53 rotates in the opposite direction, driving the carrier platform 4 to reset to the initial position, waiting for the next operation.

[0033] Furthermore, the top of the base 2 is threaded with four screws 3, which fix the base 2 to the top of the offshore platform 1, facilitating stable installation of the base 2.

[0034] In this invention, during use, the base 2 is stably installed on the offshore platform 1 by screwing down the screws 3. The main body or key components of the offshore wind turbine to be moved are placed on the support platform 4. The anti-slip protrusions 9 and the baffle 8 ensure the stable placement of the components. The servo motor 53 is started. After being reduced in speed by the reducer 56, the servo motor 53 drives the rotating shaft 59 and the drive gear 55 to rotate. The drive gear 55 meshes with the rack 58 to drive the support platform 4 to move smoothly along the slide rail 61. During this process, stable guidance can be achieved by the rolling of the guide wheel 63 on the slide rail 61 and the sliding of the slide rod 64 in the slide groove 62. At the same time, a shock-absorbing rubber pad 68 is installed between the upper and lower plates to absorb the vibration during the swaying and translation at sea. When the swaying and translation occur at sea, there will be a tendency for vibration movement. The shock-absorbing rubber pad 68 can absorb and cancel this vibration movement tendency, further improving the stability during translation and sliding.

[0035] The encoder 54 allows for precise control of the rotation speed and angle of the servo motor 53, thereby enabling accurate adjustment of the translation speed and displacement of the platform 4. Simultaneously, the high-precision distance sensor 51 further enhances the accuracy of the platform 4's movement. When the platform 4 reaches the target position, the servo motor 53 stops and brakes, while the cylinder 73 activates, driving the positioning rod 74 downwards. Guided by the wide slot 72 and the tip of the positioning rod 74, the positioning rod 74 precisely inserts into the positioning groove 71, completing the precise positioning of the platform 4. After the translation operation is completed, the cylinder 73 drives the positioning rod 74 out of the positioning groove 71, and the servo motor 53 reverses its rotation, resetting the platform 4 to its initial position, ready for the next operation.
