Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and in particular to an automatic leveling and buffering device for a floating offshore wind power boarding platform. Background Technology

[0002] During the maintenance and repair of offshore wind turbines, the boarding platform on the boarding vessel is usually connected to the ladder of the floating offshore wind turbine platform. This allows staff to enter the nacelle of the floating offshore wind turbine platform for maintenance and repair work. Due to the waves, in order to ensure the stability of the boarding platform during the boarding process, an automatic leveling and buffering device is usually used to connect the boarding platform to the boarding vessel to ensure the connection efficiency and quality of the boarding platform. Existing automatic leveling and buffering devices are usually composed of a support frame, hydraulic rods and the main body of the gangway.

[0003] For example, invention patent application CN202110904950.7 discloses an offshore wind power operation and maintenance boarding device, specifically including an operation and maintenance vessel and a pipe pile. The pipe pile is moored on one side of the operation and maintenance vessel, and a boarding component is provided on the pipe pile. The boarding component has an adjustment mechanism at its bottom. The boarding component includes two hand-held climbing frames, a climbing ladder, and a climbing support plate. The adjustment mechanism includes a base plate, with multiple elastic connecting rods fixed between the top of the base plate and the bottom of the climbing support plate. Four fixing plates are fixed at the bottom of the climbing support plate, and a placement plate is fixed between the four fixing plates. Two support bases are symmetrically arranged on the placement plate, and a first rotating shaft is provided between the two support bases. This invention allows the adjustment mechanism to adjust the tilt angle of the base plate, thereby increasing the deck position of the operation and maintenance vessel and the overlapping space of the climbing support plate. This provides safety protection for operation and maintenance engineers, and the climbing is less affected by the turbulence of the operation and maintenance vessel, improving safety.

[0004] However, in the marine environment, the salt naturally present in the air evaporates to form salt spray. At the same time, microorganisms and algal spores that are widely present in the ocean can adhere to the surface of the gangway's main steps with the sea breeze. The gangway's main steps are mostly made of metal and are in a humid environment for a long time. Although their surfaces are coated with anti-corrosion coatings, the coatings will break down with wear and natural aging, causing salt spray to accumulate directly on the metal body and cause corrosion. The microorganisms and algal spores attached to the steps will gradually form a biofilm. The biofilm not only has strong adhesion, but also further traps the salt spray, forming a local high concentration of salt water on the steps to accelerate corrosion. In the end, the steps will develop rust spots, pits, and become uneven, causing structural damage. At the same time, the biofilm and salt spray residue will make the steps more slippery, especially in humid conditions, which can easily cause people to fall. Summary of the Invention

[0005] In view of this, the present invention provides an automatic leveling and buffering device for a floating offshore wind power boarding platform, which has the feature of automatically breaking salt spray and biofilm adhesion during the leveling process.

[0010] Furthermore, a second drive motor is bolted to the right end face of the auxiliary frame; the output shaft of the second drive motor is coaxially and fixedly connected to the rotating shaft of the support frame.

[0011] Furthermore, two fixing hooks are symmetrically fixedly connected to the end of the main body of the gangway; a connecting rod is bolted between the two fixing hooks.

[0012] Furthermore, a control gear ring is fixedly connected to the left side of the auxiliary frame; the control gear ring is disposed inside the sealing shell; a control gear is coaxially fixedly connected to the left side of the transmission shaft; the control gear is disposed inside the sealing shell; the control gear meshes with the control gear ring.

[0013] Furthermore, a second bevel gear is coaxially fixedly connected to the outer center of the transmission shaft; a first bevel gear is coaxially fixedly connected to the top surface of the connecting shaft; the first bevel gear meshes with the second bevel gear.

[0014] Furthermore, a first pulley is coaxially fixedly connected to the lower part of the connecting shaft; a second pulley is coaxially fixedly connected to the lower part of the auxiliary shaft; the second pulley and the first pulley are connected by a transmission belt.

[0015] Furthermore, each of the multiple sets of receiving grooves has a sliding plate slidably connected to it; each of the multiple sets of mounting slides has a set of auxiliary protrusions fixedly connected to its top surface; each of the multiple sets of pedal bodies has a set of auxiliary holes on its top surface; the multiple sets of auxiliary holes are aligned with the positions of the multiple sets of auxiliary protrusions; each of the multiple sets of auxiliary protrusions is a hemispherical structure; a control cam is coaxially fixedly connected to the outside of the auxiliary rotating shaft; each of the multiple sets of mounting slides has a set of connecting springs fixedly connected to its bottom surface; the ends of the multiple sets of connecting springs are fixedly connected to the multiple sets of receiving grooves; an auxiliary rod is fixedly connected to the outside of each of the multiple sets of mounting slides; the end of the auxiliary rod is slidably connected to the support frame; a control push plate is fixedly connected to the end of the auxiliary rod; the control push plate is aligned with the position of the control cam.

[0016] Beneficial effects This invention, through the installation of a buffer plate, enables the buffer plate to actively compensate for the vertical swaying of the hull caused by waves. Combined with the elastic adjustment of the spring damper, it can counteract the impact of hull swaying on the boarding platform, buffering the boarding platform and keeping the main body of the gangway in a relatively horizontal state. This avoids the platform tilting or shaking due to severe hull undulations, allowing the main body of the gangway to dynamically adapt to the hull movement and maintain the stability of the gangway. This effectively improves the practicality of the automatic leveling and buffering device and makes it more convenient to use.

[0017] By activating the hydraulic push rod to move the fixed frame upward, the height of the gangway body is adjusted. By activating the first drive motor, the mounting plate is rotated, adjusting the horizontal angle of the gangway body. By activating the second drive motor, the support frame is rotated, adjusting the tilt angle of the gangway body. The coordinated adjustment of the height, horizontal angle, and tilt angle of the gangway body constitutes the complete leveling process of the floating offshore wind power boarding platform, ensuring that the gangway body reaches a horizontal state to meet the safety boarding requirements, and further improving the practicality of the automatic leveling and buffer device.

[0018] During the rotation of the support frame, a control gear ring drives a control gear, which in turn drives a transmission shaft. This, in turn, drives a series of transmissions to rotate a control cam. The cam's rotation pushes a control push plate, which in turn moves an auxiliary rod. This movement of the auxiliary rod causes the mounting slide to move within the receiving groove and stretches the connecting spring. As the mounting slide slides, it pushes the auxiliary protrusion out of the auxiliary hole. When the control push plate loses the pressure of the control cam, the mounting slide returns to its original position due to the spring's rebound. The interaction between the control cam and the connecting spring causes the auxiliary protrusion to repeatedly extend and retract within the auxiliary hole. During leveling, the auxiliary protrusion repeatedly extends and retracts, its spherical edge directly contacting the pedal surface, physically scraping away solid deposits such as sea salt crystals and sand. Furthermore, the continuous movement of the auxiliary protrusions disrupts the salt spray adhesion balance on the metal surface, reducing chloride ion accumulation. Simultaneously, mechanical scraping can peel off the initially formed biofilm, blocking its direct contact with the metal substrate and delaying corrosion and biofilm adhesion on the pedal body. Even with infrequent maintenance and repairs, salt spray accumulation and biofilm formation still require time. During maintenance and repair cycles, even if a thin salt film forms on the pedal, the auxiliary protrusions can shatter the initially formed thin salt film, disrupting the salt spray deposition balance and reducing the overall corrosion risk. Moreover, the periodic movement of the auxiliary protrusions provides real-time feedback on whether the support frame is operating normally. If the movement of the auxiliary protrusions is irregular, it indicates that the support frame is slightly stuck, reminding staff to lubricate the support frame in time, effectively improving the convenience of the automatic leveling and buffering device.

A sealing shell 113 is fixedly connected to the left side of the top surface of the rotating plate 108; the sealing shell 113 is located on the left side of the auxiliary frame 112; a transmission shaft 121 is rotatably connected inside the support frame 116; an auxiliary guide groove 111 is provided inside the fixed frame 106; a connecting shaft 123 is rotatably connected inside the support frame 116; the positions of the connecting shaft 123 and the transmission shaft 121 are aligned; an auxiliary shaft 127 is rotatably connected to the front of the support frame 116; the positions of the auxiliary shaft 127 and the connecting shaft 123 are aligned; and a receiving groove 131 is provided inside each of the multiple pedal bodies 118.

[0037] The buffer plate 101 is symmetrically fixedly connected to two guide sliders 104 on its exterior; two guide grooves 103 are symmetrically opened inside the mounting frame 1; the two guide sliders 104 are slidably connected in the two guide grooves 103 respectively; the bottom end face of the buffer plate 101 is fastened to multiple sets of spring dampers 102 in a rectangular array shape with screws; the ends of the multiple sets of spring dampers 102 are all bolted to the bottom end face of the inner wall of the mounting frame 1.

[0038] A first drive motor 107 is bolted to the bottom end face of the fixed frame 106; the output shaft of the first drive motor 107 is fixedly connected to the bottom end face of the mounting plate 108; the output shaft of the first drive motor 107 is located inside the fixed frame 106.

[0039] Two guide rods 109 are symmetrically fixedly connected to the output shaft of the first drive motor 107; both guide rods 109 are set inside the fixed frame 106; a guide ball 110 is fixedly connected to the end of each of the two guide rods 109; both guide balls 110 are set inside the fixed frame 106; and both guide balls 110 are slidably connected inside the auxiliary guide groove 111.

[0040] Among them, a second drive motor 115 is bolted to the right end face of the auxiliary frame 112; the output shaft of the second drive motor 115 is coaxially fixedly connected to the rotating shaft of the support frame 116.

[0041] The gangway body 117 has two fixed hooks 119 symmetrically fixed at its end; a connecting rod 120 is bolted between the two fixed hooks 119.

[0042] The specific usage and function of this embodiment: In this invention, the mounting frame 1 facilitates the fixing of the device at the boarding gate of the boarding vessel. When boarding the floating offshore wind power platform, the buffer plate 101 can slide vertically along the mounting frame 1. During the sliding process of the buffer plate 101, the guide slider 104 can slide within the guide groove 103 to provide a horizontal limit for the buffer plate 101. This allows the buffer plate 101 to actively follow the vertical sway of the hull caused by the waves to compensate for displacement. Combined with the elastic adjustment of the spring damper 102, the impact of the hull sway on the boarding platform can be offset. To cushion the boarding platform, when boarding the floating offshore wind power platform, the hydraulic push rod 105 is activated to move the fixed frame 106 upward, adjusting the height of the gangway body 117 so that it can better connect with the ladder of the floating offshore wind power platform. The first drive motor 107 is activated, causing the mounting plate 108 to rotate. As the mounting plate 108 rotates, the horizontal angle of the gangway body 117 is adjusted, ensuring better alignment between the gangway body 117 and the ladder of the floating offshore wind power platform. During the rotation of the output shaft of the first drive motor 107, the two guide rods 109 will rotate. As the two guide rods 109 rotate, the two guide balls 110 will slide along the auxiliary guide groove 111. The sliding of the guide balls 110 guides and limits the output shaft of the first drive motor 107, ensuring the stability of the mounting plate 108 during rotation. By starting the second drive motor 115, the second drive motor 115 drives the support frame 116 to rotate. The rotation of the support frame 116 adjusts the tilt angle of the gangway body 117, allowing the fixed hook 11 to... 9 can be better hooked onto the ladder of the floating offshore wind power platform. At the same time, through the coordinated adjustment of the height, horizontal angle and tilt angle of the main body 117 of the gangway, the main body 117 of the gangway is made to reach a horizontal state to meet the safety boarding requirements, so as to achieve the leveling of the main body 117 of the gangway. The setting of the step body 118 makes it convenient for workers to board the floating offshore wind power platform. The setting of the fixing hook 119 makes it easy to connect the main body 117 of the gangway to the ladder of the floating offshore wind power platform. The setting of the connecting rod 120 will strengthen the strength between the fixing hooks 119.

[0043] Example 2: Based on implementation one, please refer to Figures 7 to 14As shown, it includes: a control gear ring 114, a control gear 122, a first pulley 124, a first bevel gear 125, a second bevel gear 126, a second pulley 128, a control cam 129, an auxiliary hole 130, a receiving groove 131, a mounting slide plate 132, a connecting spring 133, an auxiliary rod 134, a control push plate 135, and an auxiliary protrusion 136. The control gear ring 114 is fixedly connected to the left side of the auxiliary frame 112. The control gear ring 114 is disposed inside the sealing shell 113. The control gear 122 is coaxially fixedly connected to the left side of the transmission shaft 121. The control gear 122 is disposed inside the sealing shell 113. The control gear 122 meshes with the control gear ring 114.

[0044] Among them, a second bevel gear 126 is coaxially fixedly connected to the outer center of the transmission shaft 121; a first bevel gear 125 is coaxially fixedly connected to the top surface of the connecting shaft 123; the first bevel gear 125 meshes with the second bevel gear 126.

[0045] The lower part of the connecting shaft 123 is coaxially fixedly connected to a first pulley 124; the lower part of the auxiliary shaft 127 is coaxially fixedly connected to a second pulley 128; the second pulley 128 and the first pulley 124 are connected by a transmission belt.

[0046] Each of the multiple sets of receiving grooves 131 has a sliding mounting plate 132 slidably connected within it; the top surfaces of the multiple sets of mounting plates 132 are fixedly connected to multiple sets of auxiliary protrusions 136; the top surfaces of the multiple sets of pedal bodies 118 are provided with multiple sets of auxiliary holes 130; the multiple sets of auxiliary holes 130 are respectively aligned with the positions of the multiple sets of auxiliary protrusions 136; the multiple sets of auxiliary protrusions 136 are all hemispherical structures; a control cam 129 is coaxially fixedly connected to the outside of the auxiliary rotating shaft 127; the bottom surfaces of the multiple sets of mounting plates 132 are fixedly connected to multiple sets of connecting springs 133; the ends of the multiple sets of connecting springs 133 are respectively fixedly connected within the multiple sets of receiving grooves 131; an auxiliary rod 134 is fixedly connected to the outside of the multiple sets of mounting plates 132; the end of the auxiliary rod 134 is slidably connected within the support frame 116; a control push plate 135 is fixedly connected to the end of the auxiliary rod 134; the control push plate 135 is aligned with the position of the control cam 129.

[0047] The specific usage and function of this embodiment: In this invention, during the rotation of the support frame 116, the control gear ring 114 drives the control gear 122 to rotate. As the control gear 122 rotates, it drives the transmission shaft 121 to rotate. Since the diameter of the control gear ring 114 is larger than that of the control gear 122, even with a small rotation amplitude, the control gear 122 will rotate multiple times during the rotation of the support frame 116. During the rotation of the transmission shaft 121, the second bevel gear 126 rotates. As the second bevel gear 126 rotates, it drives the first bevel gear 125, which meshes with it, to rotate. During the rotation of the connecting shaft 123, the first pulley 124 rotates. As the first pulley 124 rotates, it drives the transmission belt... The second pulley 128 rotates, which in turn drives the control cam 129 to rotate. As the control cam 129 rotates, it pushes the control push plate 135, causing the control push plate 135 to move the auxiliary rod 134. As the auxiliary rod 134 moves, it causes the mounting slide plate 132 to move within the receiving groove 131 and stretches the connecting spring 133. As the mounting slide plate 132 slides, it pushes the auxiliary protrusion 136 out of the auxiliary hole 130. When the control push plate 135 loses the pressure of the control cam 129, the mounting slide plate 132 will return to its original position with the rebound of the connecting spring 133. Thus, through the cooperation of the control cam 129 and the connecting spring 133, the auxiliary protrusion 136 repeatedly pushes out and retracts within the auxiliary hole 130.
