Description

Technical Field

[0001] This utility model relates generally to the technical field of containers, and more specifically to a wind power operation and maintenance cabin. Background Technology

[0002] Operation and maintenance of wind turbines is an important area in the wind power industry. There are generally two existing operation and maintenance methods: one is to use maintenance vessels at sea to perform maintenance on offshore wind power equipment through multiple dockings; the other is to use multiple large hoisting and maintenance equipment on land to perform multiple hoisting and disassembly operations to replace large components and repair specific components.

[0003] Existing maintenance vessels integrate wind power maintenance equipment and are used when wind turbines need to be inspected and maintained. However, when there is no need for inspection and maintenance, the maintenance vessels cannot be used for other purposes such as transportation, resulting in waste of maintenance vessels and increasing the maintenance cost of wind turbines.

[0004] Similarly, large land-based crane operation and maintenance equipment vehicles are difficult to disassemble and use for other purposes when there is no need for operation and maintenance, which increases operation and maintenance costs and makes them difficult to use for the operation and maintenance of offshore wind turbines.

[0059] According to the wind power maintenance cabin 160 of this utility model, maintenance equipment 140 is integrated inside a container body 110. The container body 110 is connected to the nacelle 101 of the wind turbine 100 via a mounting component 130, allowing the container body 110 to fit snugly against the side of the nacelle 101 of the wind turbine 100. This ensures a stable connection between the container body 110 and the side of the nacelle 101 of the wind turbine 100, enabling maintenance work on the wind turbine 100 to be performed using the maintenance equipment 140, such as a lifting device 141. This eliminates the need for long-term occupation of maintenance vessels or other large lifting equipment, improving maintenance efficiency and reducing maintenance costs. Furthermore, the container body 110 can be installed on various ships, vehicles, and equipment, offering flexible installation and thus expanding the applicability of the wind power maintenance cabin 160. In addition, when the container body 110 is attached to the nacelle 101 of the wind turbine 100, the maintenance port 126 of the wind power maintenance cabin 160 can be aligned with the maintenance hatch of the nacelle 101 of the wind turbine 100, thereby facilitating maintenance personnel to perform maintenance on the wind turbine 100.

[0060] According to a specific embodiment of this utility model, the container body 110 of the wind power operation and maintenance cabin 160 can be a 40-foot standard container, which makes it easy to install the wind power operation and maintenance cabin 160 on various ship or vehicle bodies and has a wide range of applications. The container body 110 will be described below with reference to the accompanying drawings.

[0061] Reference Figure 2 and Figure 4 The container body 110 includes bottom longitudinal beams 118, bottom end beams 117, and steel floor 120 (see...). Figure 1The container includes bottom corner brackets 114, top corner brackets 112, corner posts 113, top longitudinal beams 116, top beams 115, end wall panels 124, and side wall panels 123. The bottom longitudinal beam 118 extends along the length direction (second direction D2) of the container body 110, and the bottom transverse beam extends along the width direction (first direction D1) of the container body 110. The bottom end beam 117 is located at the end of the bottom longitudinal beam 118, and the bottom corner brackets 114 are connected to the ends of the bottom longitudinal beam 118 and the bottom end beam 117, respectively. A steel floor 120 is positioned above the bottom longitudinal beam 118 and the bottom end beam 117 along the height direction Z, and the bottom surface of the steel floor 120 is connected to the bottom longitudinal beam 118 and the bottom end beam 117. Corner post 113 extends along the height direction Z, with its bottom end connected to bottom corner piece 114 and its top end connected to top corner piece 112 (for corner posts 113 without the hanging assembly 130). Top longitudinal beam 116 extends along the second direction D2 and connects to top corner piece 112, with top beam 115 located at the end of top longitudinal beam 116 and connected to top corner piece 112. Side wall panel 123 is located at both ends of bottom beam 117 along the second direction D2, positioned between top longitudinal beam 116 and bottom longitudinal beam 118, and both ends of side wall panel 123 are connected to corner post 113. End wall panel 124 is located at both ends of bottom longitudinal beam 118 along the second direction D2, positioned between top beam 115 and bottom beam 117, and both sides of end wall panel 124 are connected to corner post 113.

[0062] Combination Figure 5 As shown above, the container body 110 is not equipped with a top plate, which makes the top structure of the container body 110 form an opening 111, which facilitates the lifting device 141 of the maintenance equipment 140 to extend out of the container body 110 for maintenance work.

[0063] Reference Figure 4 For the side wall panel 123 of the container body 110 along the first direction D1 near the wind turbine 100, a manhole 125 is also provided. When the wind power maintenance cabin 160 is connected to the side of the nacelle 101 of the wind turbine 100, maintenance personnel can enter the nacelle 101 of the wind turbine 100 through the manhole 125 to carry out maintenance work, and can also inspect the wind turbine 100 through the inspection port 126.

[0064] Optionally, refer to Figure 1 and Figure 5The lifting device 141 can be a telescopic double crane, which includes a long boom crane 142 and a short boom crane 143. When the wind turbine maintenance cabin 160 is working, the short boom crane 143 can lift the top cover of the nacelle 101 of the wind turbine 100, and the long boom crane 142 can lift the equipment of the wind turbine 100. The chassis of the lifting device 141 is fixed to the bottom frame (bottom longitudinal beam 118, steel floor 120 or bottom end beam 117) of the container body 110, and the crane can be switched according to the lifting needs.

[0065] Optionally, refer to Figure 1 The maintenance equipment 140 also includes a maintenance toolbox 144, which contains maintenance tools such as wrenches, jacks, and digital multimeters. The bottom of the toolbox is fixed to the base frame of the container body 110 through the mounting interface at the bottom of the box body to ensure the smooth operation of equipment maintenance.

[0066] Optionally, the maintenance equipment 140 also includes a fire toolbox 145, which contains fire extinguishers and other fire-fighting equipment. The fire toolbox 145 can be fixed to the base frame of the container body 110 through an installation interface to ensure fire safety during maintenance.

[0067] Optionally, the maintenance equipment 140 also includes a work platform 146, which can be fixed to the base frame of the container body 110 via an installation interface. The work platform 146 can be located on one side of the maintenance toolbox 144 to facilitate the inspection and maintenance of parts.

[0068] In addition, refer to Figure 1 The container body 110 can also be equipped with a fixing bracket 119, which can be used to fix the long boom crane 142 and short boom crane 143 of the lifting device 141 by means of fasteners or binding components. The fixing bracket 119 can be arranged on the top longitudinal beam 116, the side wall plate 123 or the bottom longitudinal beam 118, which can provide a fulcrum for fixing the lifting device 141, thus enhancing safety.

[0069] Optionally, the container body 110 may also be equipped with and have reserved installation interfaces or fastening points for the lifting device 141, maintenance toolbox 144, fire toolbox 145 and work platform 146 of the maintenance equipment 140, thereby speeding up the installation of the maintenance equipment 140.

[0070] Optionally, the wind power operation and maintenance cabin 160 also includes a soft canopy 150, which is disposed on the top of the container body 110. At least one end of the soft canopy 150 is movably connected to the container body 110 along the length direction (second direction D2) of the container body 110, so that the soft canopy 150 closes the opening 111 when unfolded, thereby reducing the impact of external rainwater or dust on the operation and maintenance equipment 140 inside the container body 110. For example, the first end of the soft canopy 150 can be fixed to one end of the container body 110, and the second end of the soft canopy 150 can be movably connected to the container body 110 (specifically, it can be the top longitudinal beam 116) along the length direction (second direction D2) of the container body 110, which can also realize the opening and closing of the container body 110. Alternatively, both ends of the soft canopy 150 can be movably connected to the container body 110 along the length direction of the container body 110, which can also realize the opening and closing of the container body 110.

[0071] Furthermore, the top longitudinal beam 116 of the container body 110 can be equipped with a slide rail or slide groove to cooperate with the end of the soft tarpaulin 150 to realize the opening and closing of the soft tarpaulin.

[0072] The specific structure of the mounting component 130 will now be described in conjunction with the accompanying drawings.

[0073] Optionally, refer to Figure 2 and Figure 3 The mounting assembly 130 includes a hook tongue 132 and a hook 131. One of the hook tongue 132 and the hook 131 is located on the side of the container body 110, and the other of the hook tongue 132 and the hook 131 is used for mounting on the nacelle 101 of the wind turbine 100. The hook tongue 132 is connected to the hook 131, thereby connecting the container body 110 to the nacelle 101 of the wind turbine 100, which is convenient to operate and has a stable structure.

[0074] Furthermore, the hook 131 is disposed on the side of the nacelle 101 of the wind turbine 100, and the hook tongue 132 is disposed on the side of the container body 110. The top structure of the hook 131 forms a mounting groove 133, which is a recess. When the wind turbine maintenance cabin 160 is connected to the nacelle 101 of the wind turbine 100, the hook tongue 132 enters the mounting groove 133, so that the mounting groove 133 can limit the hook tongue 132 along the first direction D1, thereby fixing the container body 110.

[0075] Optionally, the hook tongue 132 is disposed on the inner side of the side wall of the container body 110 for attaching to the nacelle 101 of the wind turbine 100. In other words, the hook tongue 132 does not protrude from the container body 110, thereby further protecting the hook tongue 132. It can also be retracted to reduce the distance between the container body 110 and the nacelle 101 of the wind turbine 100 when the container body 110 is attached to the nacelle 101 of the wind turbine 100, making the attachment of the container body 110 to the nacelle 101 of the wind turbine 100 more stable.

[0076] Optionally, the container body 110 can be twist-locked to the nacelle 101 of the wind turbine 100 via the bottom corner fittings 114, and the bottom of the container body 110 can also be connected to the nacelle 101 of the wind turbine 100 via fasteners, which can further stabilize the wind power operation and maintenance cabin 160.

[0077] Combination Figure 4 As shown, the first direction D1 is perpendicular to the length of the container body 110, and the hook tongue 132 extends along the second direction D2, which is parallel to the length of the container body 110, making it easy for the hook tongue 132 to engage with the hook 131. The hook tongue 132 is arranged at both ends of the container body 110 along the second direction D2, which is parallel to the length of the container body 110, so that both ends of the container body 110 are connected to the nacelle 101 of the wind turbine 100, making the connection between the wind turbine maintenance cabin 160 and the wind turbine 100 more stable.

[0078] Optionally, refer to Figure 3 The mounting assembly 130 also includes a housing 134, which is disposed on the container body 110 (specifically, the top corner piece 112 and the corner post 113, detailed below) and forms an accommodating space 121 with the container body 110. The hook tongue 132 is disposed in the accommodating space 121. A mounting interface 122 is provided on the side of the accommodating space 121 away from the container body 110 along the first direction D1. The mounting interface 122 is used to connect the hook tongue 132 and the hook 131 together through the hook 131, thereby protecting the hook tongue 132 and preventing the wind power maintenance cabin 160 from damaging the hook tongue 132 during transportation.

[0079] Optionally, along the first direction D1, the box body 134 does not protrude from the container body 110, which can keep the side of the container body 110 flat and also help protect the box body 134.

[0080] Optionally, refer to Figure 3On the side of the container body 110 near the wind turbine 100, the box body 134 is located between the top corner piece 112 and the corner post 113. The top of the box body 134 is open and connected to the bottom surface of the top corner piece 112, while the bottom of the box body 134 is connected to the top of the corner post 113. The hook tongue 132 is connected to the bottom surface of the top corner piece 112. This ensures that the stress of the container body 110 when connected to the wind turbine 100 is not concentrated in the box body 134, but is transferred to the top corner piece 112 through the hook tongue 132, making it more stable and safer.

[0081] Specifically, refer to Figure 3 The housing 134 includes three side wall panels 135 and a bottom panel 136. The three side wall panels 135 are connected together, and the top of each of the three side wall panels 135 is connected to the bottom surface of the corner piece 112, and the bottom of each of the three side wall panels 135 is connected to the corner post 113. The cross-section of the three side wall panels 135 perpendicular to the height direction Z is U-shaped, and the bottom panel 136 is connected to the side wall panels 135. Thus, the inner wall of the side wall panels 135, the top surface of the bottom panel 136, and the bottom surface of the corner piece 112 form a receiving space 121. The hanging interface 122 of the receiving space 121 is arranged on the side of the housing 134 near the wind turbine 100, so that when the wind power operation and maintenance cabin 160 is installed, the hook 131 is inserted into the receiving space 121 to engage with the hook tongue 132.

[0082] Optionally, refer to Figure 3 The end of the bottom panel 136 near the hanging interface 122 along the first direction D1 is lower than the end of the bottom panel 136 away from the hanging interface 122 along the first direction D1, thereby draining rainwater accumulated in the box 134 and reducing erosion of the box 134 and the hook tongue 132. The bottom panel 136 can be constructed as an inclined plate structure, and the lower end of the bottom panel 136 can also extend along the height direction Z to the top of the corner post 113, which can prevent rainwater from entering the corner post 113.

[0083] A specific embodiment of this utility model also provides a maintenance vessel, including a hull and a wind power maintenance cabin 160 as described above. The wind power maintenance cabin 160 includes a container body 110, which is detachably connected to the hull. According to this utility model, the maintenance vessel can transport the wind power maintenance cabin 160 to the location of the wind turbine 100 for maintenance work, or use hoisting equipment to connect the wind power maintenance cabin 160 to the wind turbine 100. The hull can also continue to install and transport other wind power maintenance cabins 160 to other wind turbine 100 locations for maintenance work, resulting in high maintenance efficiency and low maintenance costs.

[0084] A specific embodiment of this utility model also provides a maintenance vehicle, including a vehicle body and a wind power maintenance cabin 160 as described above. The wind power maintenance cabin 160 includes a container body 110, which is detachably connected to the vehicle body. According to this utility model, the maintenance vehicle can transport the wind power maintenance cabin 160 to the location of the wind turbine 100 for maintenance work, or use hoisting equipment to connect the wind power maintenance cabin 160 to the wind turbine 100.
