Description

[0001] The present application relates to the technical field of ocean engineering, and particularly relates to a wind power installation platform. BACKGROUND

[0002] China is rich in offshore wind energy resources, and the development of offshore wind turbines is developing rapidly. Offshore wind turbine installation ships have also emerged accordingly. However, due to the poor sea state adaptability of floating ships, the bottom sitting type wind power installation ship has high requirements for water depth and seabed geology. Therefore, most of the newly built wind power installation ships on the market are self-elevating wind power installation platforms. With the increasing large-scale of offshore wind turbines, the requirements for the lifting height of the self-elevating wind power installation platform are also increasing. If the lifting height of the crane configured on the wind turbine installation platform cannot meet the lifting height requirements of the future large-scale wind turbines, the height of the main hull of the wind turbine installation platform needs to be increased to make up for the insufficient lifting height of the crane.

[0003] However, increasing the height of the main hull of the wind turbine installation platform will cause a large air gap in the main hull, increase the height of the deck from the water surface, and make it difficult for personnel to quickly reach the water surface, thereby causing difficulties in personnel escape and evacuation. SUMMARY

DETAILED DESCRIPTION

[0030] Typical embodiments embodying the features and advantages of the present application will now be described in detail. It should be understood, however, that the application can be practiced in various ways without being limited to any particular embodiment, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

[0031] In the description of the present application, it is to be understood that the indications of directions or positional relationships (such as up, down, left, right, front, and back, etc.) in the embodiments shown in the drawings are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation. When the positions of these elements are changed, the indications of directions are also changed accordingly.

[0032] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features referred to. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0033] When working at sea, the personnel escape system is usually configured with lifeboats and rafts, and equipped with boarding ladders. However, the boarding ladders are suitable for use with the support of the main hull plate or structure. If there is no main hull plate as support, the boarding ladders will sway and twist when in use, which will cause safety hazards to the boarding personnel. For self-elevating platforms with small air gaps, portable mobile boarding steel ladders can be set and used. However, the portable steel ladders need to be temporarily arranged within the hoisting range of the crane for use, so that the portable steel ladders can be moved for use by the crane. However, the length of the portable steel ladders is not suitable for large air gap platforms. In addition, when the crew chooses to use the maintenance steel ladders on the pile legs to get to the water surface, and the distance between the steel ladders on the pile legs and the lifeboats lowered from the ship side is far, the personnel will have difficulty boarding the lifeboats.

[0034] In addition, in actual use, in addition to the requirement that the wind power installation platform can install large wind turbines, the wind power installation platform is also required to have the functions of module transportation and installation. If the lifting height of the crane configured on the wind turbine installation platform itself cannot meet the future lifting height requirement of large wind turbines, the height of the main hull of the wind turbine installation platform needs to be increased to compensate for the insufficient lifting height of the crane. This will cause a large air gap on the wind turbine installation platform, and further cause difficulties in personnel escape and evacuation.

[0035] Therefore, the wind power installation platform is proposed to solve the above problems.

[0036] The scheme is further illustrated by the following embodiments:

[0037] In this embodiment, the up-down direction of the Figure 3 is the horizontal direction, the left-right direction is the vertical direction, the outward direction perpendicular to the paper is the upward direction, and the inward direction perpendicular to the paper is the downward direction.

[0038] Please refer to Figure 1 , Figure 2 , the wind power installation platform of the present embodiment includes a main hull 10, a life-saving ladder 20, a pile leg 31, a pile shoe 32, and a crane 33. The pile shoe 32 is installed at the bottom of the pile leg 31, the main hull 10 is installed on the pile leg 31, and the crane 33 is installed on the main hull 10 and located at the tail of the main hull 10. The life-saving ladder 20 is installed on the main hull 10 and can be extended to the water surface to allow escape personnel to get to the water surface through the life-saving ladder 20.

[0039] It should be noted that the pile shoe 32 is used to prevent the pile leg 31 from sinking due to gravity, and the pile leg 31 is used to support the main hull 10 and the crane 33 to prevent the main hull 10 and the crane 33 from sinking. The crane 33 is used to hoist cargo. And the crane 33 is also connected at the top of the pile leg 31 to disperse the weight of the crane 33 to the pile leg 31, preventing the crane 33 from damaging the main hull 10 due to excessive weight.

[0040] In addition, the main hull 10 is provided with a bow living area 34 and an escape system 35. The bow living area 34 is arranged at the bow of the main hull 10, and the escape system 35 is located on the same deck and is in communication with each other to enable personnel to move to the escape system 35 in time. It should be noted that in this embodiment, the escape system 35 includes lifeboats, life rafts, etc.

[0041] Referring to Figures 1-4 The main hull 10 is also provided with a main deck 11 and an outer plate 12 connected to each other, that is, the two side edges of the main deck 11 are connected to the top of the outer plate 12.

[0042] The escape valve ladder 20 includes a support 21, a plurality of slides 22, and a slide rail 24. In this embodiment, the escape valve ladder 20 is provided with four slides 22 of the same height. It should be noted that in other embodiments, the number of slides 22 can be set to other numbers.

[0043] In addition, the support 21 is installed on the main deck 11 and located at the top of the outer plate 12, that is, the support 21 is located at the edge of the main deck 11 and at the top of the outer plate 12. A plurality of slides 22 are connected in sequence in the direction away from the outer plate 12, and each slide 22 is provided with a pulley 23 on the transverse side wall thereof. The slide rail 24 includes a first slide rail 241 fixed on the support 21 and a second slide rail 242 fixed on the slide 22.

[0044] As Figure 4As shown, in the embodiment, between two adjacent slides 22, the second slide rails 242 are fixed on the slide 22 close to the outer plate 12, that is, the slide 22 close to the outer plate 12 in the longitudinal direction is provided with the second slide rails 242. And the second slide rails 242 are transversely spaced on the side of the slide 22 away from the outer plate 12, that is, the second slide rails 242 are provided with two, and the two second slide rails 242 are transversely spaced on the side of the slide 22 away from the outer plate 12 in the longitudinal direction. The first slide rails 241 are transversely spaced on the support 21, that is, the first slide rails 241 are also provided with two, and the two first slide rails 241 are spaced on the support 21. That is, in the embodiment, the first slide rails 241 are spaced on the support 21, the pulleys 23 are respectively arranged on the two lateral walls of the slide 22 in the transverse direction, and the second slide rails 242 are also spaced on the side away from the outer plate 12 in the longitudinal direction. But it should be noted that among the plurality of slides 22, the slide 22 farthest away from the outer plate 12 is not provided with the second slide rail 242.

[0045] As shown in FIG. 1, Figure 5 , Figure 6 The pulley 23 is slidably connected in the slide rail 24, so that the slide 22 can extend along the outer plate 12 to the water surface. Among them, in the embodiment, the pulley 23 on the slide 22 closest to the outer plate 12 is slidably connected to the first slide rail 241 arranged on the support 21, and the pulleys 23 on the remaining plurality of slides 22 are slidably connected to the second slide rails 242 on each slide 22 in the longitudinal direction away from the outer plate 12, so that the pulleys 23 of each slide 22 can slide along the slide rail 24, so that each slide 22 extends downward in turn until reaching the water surface, thereby facilitating personnel escape. At the same time, the pulleys 23 of each slide 22 can also slide upward along the slide rail 24, so that each slide 22 is folded on the support 21 to prevent seawater from corroding the slide 22.

[0046] As shown in FIG. 3, Figure 4 , Figure 9 Between two adjacent slides 22, the distance between the two slide rails 24 on the slide 22 away from the outer plate 12 is less than the distance between the two slide rails 24 on the slide 22 close to the outer plate 12. That is, in the embodiment, the distance between the adjacent slide rails 24 decreases in the longitudinal direction away from the outer plate 12. That is, the distance between the second slide rails 242 on the slide 22 closest to the outer plate 12 is less than the distance between the first slide rails 241 on the support 21, and the distance between the adjacent second slide rails 242 on the plurality of slides 22 also decreases in the longitudinal direction away from the outer plate 12.

[0047] It should be noted that, since the spacing between the adjacent slide rails 24 decreases in turn in the longitudinal direction away from the outer plate 12, the spacing between the pulleys 23 connected with the slide rails 24 also decreases in turn, that is, the lateral length of each slide 22 also decreases in turn, so that each slide 22 can be connected in turn and can be extended downward or folded together upward.

[0048] Referring to Figure 5 , the lateral two side walls of the slide 22 are provided with a plurality of pulleys 23, and the plurality of pulleys 23 are distributed along the vertical direction. Among them, the plurality of pulleys 23 are distributed along the vertical two sides of the slide 22, which can increase the contact points between the pulleys 23 on the slide 22 and the slide rails 24 on the adjacent slide 22 or the support 21, thereby increasing the smoothness when the two adjacent slides 22 or the slide 22 and the support 21 slide, preventing the phenomenon of being stuck. And enhance the connection stability between the two adjacent slides 22 or the slide 22 and the support 21, so as to reduce the shaking of the slide 22.

[0049] Referring to Figure 4 , the slide rail 24 is provided with a first side wall 243 and a second side wall 244 which are arranged in parallel along the longitudinal direction, and a connecting wall 245 connected between the first side wall 243 and the second side wall 244. Among them, the first side wall 243 is located on the side of the connecting wall 245 close to the outer plate 12, and the second side wall 244 is located on the side of the connecting wall 245 away from the outer plate 12. That is, the first side wall 243, the second side wall 244 and the connecting wall 245 jointly form a rectangular groove. At the same time, the first side wall 243, the second side wall 244 and the connecting wall 245 all extend along the vertical direction and form the slide rail 24, so that the pulley 23 can slide along the slide rail 24 in the vertical direction. It should be noted that, on the support 21 or on the same slide 22, the grooves of the two slide rails 24 arranged symmetrically in the lateral direction are oppositely arranged, so that the pulley 23 of the same slide 22 can slide in the slide rail 24 through the groove.

[0050] Further, in the embodiment, the pulley 23 is provided with a first roller 231, a second roller 232 and a third roller 233. The first roller 231, the second roller 232 and the third roller 233 roll along the first side wall 243, the second side wall 244 and the connecting wall 245 respectively. That is, in the embodiment, the first roller 231 and the second roller 232 are arranged at the end of the slide 22 in the longitudinal direction, and the third roller 233 is arranged at the end of the slide 22 in the transverse direction, that is, the first roller 231, the second roller 232 and the third roller 233 are arranged in a "pin" shape at the end of the slide 22, so that the first roller 231, the second roller 232 and the third roller 233 roll along the first side wall 243, the second side wall 244 and the connecting wall 245 respectively. It should be noted that the first roller 231, the second roller 232 and the third roller 233 roll along the first side wall 243, the second side wall 244 and the connecting wall 245 respectively, so that the first roller 231, the second roller 232 and the third roller 233 are limited between the first side wall 243, the second side wall 244 and the connecting wall 245, so that the pulley 23 can smoothly slide along the slide rail 24, reducing the shaking of the slide when sliding. And after the plurality of slides 22 are extended, the rollers of the pulley 23 and the side walls of the slide rail 24 are limited to each other, which can also ensure the stability of the connection between the slide 22 and the support 21 or between the slides 22, thereby reducing the shaking.

[0051] It should be noted that in the embodiment, the first roller 231, the second roller 232 and the third roller 233 are all rubber rollers. Of course, in some other embodiments, the first roller 231, the second roller 232 and the third roller 233 can also be arranged as rigid rollers and the like.

[0052] Referring to Figure 5 and Figure 7 , the slide 22 close to the outer plate 12 is provided with a supporting roller 25. The supporting roller 25 is installed on the side of the slide 22 facing the outer plate 12, and is located between the two first slide rails 241 in the transverse direction. After the slide 22 slides out of the support 21, the supporting roller 25 can slide along the outer plate 12 and support the slide 22.

[0053] It should be noted that in the embodiment, the supporting roller 25 is provided with a plurality of supporting rollers 25, and the plurality of supporting rollers 25 are installed on the side of the slide 22 closest to the outer plate 12 and facing the outer plate 12 in the vertical direction, so that the slide 22 can always be parallel to the outer plate 12, thereby increasing the stability of the slide 22. At the same time, the supporting roller 25 is a rubber roller, so that when the slide 22 is lowered or extended, the slide 22 avoids colliding with the outer plate 12, thereby preventing the slide 22 from damaging the paint layer of the outer plate 12 during sliding or when the ship is inclined and shaken.

[0054] Referring to Figure 4 ,Figure 7 and Figure 10 The bottom outer side of the second side wall 244 is provided with a positioning lug 246 extending in the longitudinal direction, and the top outer side of the connecting wall 245 is provided with a limiting block 247 extending in the transverse direction, the positioning lug 246 and the limiting block 247 can abut each other to limit two adjacent slide ladders 22. Wherein, the positioning lug 246 extends in the longitudinal direction and away from the side of the outer plate 12, and the limiting block 247 extends in the transverse direction and away from the side of the connecting wall 245, so that the two adjacent slide ladders 22 can abut each other during sliding, so as to prevent the pulley 23 on the adjacent slide ladder 22 from disengaging from the slide rail 24.

[0055] Referring to Figure 3 , Figure 5 and the drawings, the lifesaving valve ladder 20 further comprises a winch mechanism 26. Wherein, the winch mechanism 26 comprises a hand winch 261, a pulley block 262 and a steel wire rope 263. In the embodiment, the hand winch 261 is fixedly installed on the bottom of the support 21, i.e. on the main deck 11. The pulley block 262 is rotatably installed on the top of the support 21, one end of the steel wire rope 263 is connected to the hand winch 261, and the other end is connected to the slide ladder 22 farthest from the outer plate 12, and passes through the pulley block 262, so as to drive the plurality of slide ladders 22 to slide vertically by rotating the hand winch 261, so as to extend the plurality of slide ladders 22 to the water surface, or to retract the plurality of slide ladders 22 on the support 21.

[0056] Referring to Figure 6 and Figure 8 The slide ladder 22 farthest from the outer plate 12 is provided with a connecting frame 27. The connecting frame 27 is fixedly installed on the bottom of the slide ladder 22 and extends towards the side of the outer plate 12. One end of the steel wire rope 263 is connected to the slide ladder 22 through the connecting frame 27, and the longitudinal length of the projection of the plurality of slide ladders 22 in the vertical direction is less than the longitudinal length of the connecting frame 27, so that the connecting frame 27 drives the plurality of slide ladders 22 to slide and retract on the support 21 under the pulling of the steel wire rope 263. In the embodiment, one end of the steel wire rope 263 is connected to the end of the connecting frame 27 towards the outer plate 12, so that the connecting frame 27 is driven by the steel wire rope 263.

[0057] Therefore, when the connecting frame 27 moves upward, the connecting frame 27 and the slide ladder 22 fixed with the connecting frame 27 move upward together, and in the process of moving, the connecting frame 27 can abut against the bottom of the remaining plurality of slide ladders 22 and drive them to slide upward together, so as to retract the plurality of slide ladders 22 on the support 21. When the connecting frame 27 moves downward, the connecting frame 27 and the slide ladder 22 fixed with the connecting frame 27 move downward together, and the remaining plurality of slide ladders 22 also slide downward under the action of gravity, so as to extend the slide ladders 22.

As such, it is submitted that the foregoing description and examples have been apparent in terms of their structures and functions, and are susceptible to various changes without departing from the spirit or essence thereof.
