DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0021] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0023] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0024] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0025] As mentioned in the background technology, in the related technology, wind power operation and maintenance vessels usually use a top-to-bottom method to berth so that staff can board the wind power platform, that is, a top-to-bottom member is arranged on the wind power operation and maintenance vessel, and after the wind power operation and maintenance vessel approaches the wind power platform, the top-to-bottom member is docked with the berthing component of the wind power platform to achieve the berthing of the wind power operation and maintenance vessel.

[0026] However, in some application scenarios, wind power operation and maintenance vessels berthed in the above manner are prone to swaying and have poor stability, and there are safety hazards when workers board the wind power platform.

[0027] For example, when waves appear on the sea surface, the wavelength of the surge waves at sea is usually greater than 80 meters. However, in order to take into account both sailing power and wind and wave resistance, the current wind power operation and maintenance vessels are usually designed to be less than 40 meters in length. Due to the length of the ship, the wind power operation and maintenance ship cannot cover a long surge wave, causing the wind power operation and maintenance ship to float up and down with the waves when it leans against the mooring structure of the wind power platform, and cannot stay steadily to ensure that the operation and maintenance personnel can go up and down the wind turbine foundation.

[0028] In view of this, an embodiment of the present application provides an offshore wind power operation and maintenance vessel, which is provided with an operation and maintenance vessel body and a rotor device. The operation and maintenance vessel body is provided with a top support member for connecting with the mooring member of the wind power platform. The rotor device is provided with a plurality of drive assemblies and a plurality of rotor assemblies, so that the drive assemblies and the rotor assemblies are connected one by one. A storage cabin is opened on the operation and maintenance vessel body, and the drive assembly is arranged in the storage cabin. In this way, when the operation and maintenance vessel body drives the top support member to move toward the mooring member on the sea surface, the drive assembly and the rotor assembly are placed in the storage cabin so that To maintain the streamlined design of the operation and maintenance ship body, reduce the resistance during the route, and help improve the navigation efficiency; when the top support member moves to dock with the berthing member, the drive assembly is started by operating the drive assembly to drive the corresponding rotor assembly to move, so that the rotor assembly is extended out of the storage cabin, and then the rotor assembly is started to provide lift for the operation and maintenance ship body through the rotor assembly, so that the operation and maintenance ship body is out of contact with the sea surface, thereby avoiding the operation and maintenance ship body from being affected by the waves. The offshore wind power operation and maintenance ship provided in the embodiment of the present application has good berthing stability and small safety hazards.

[0029] Hereinafter, the present application will be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] See also Figure 1 and Figure 2The offshore wind power operation and maintenance vessel provided in the embodiment of the present application includes an operation and maintenance vessel body 100 and a rotor device 200; the operation and maintenance vessel body 100 is provided with a top support member 110 for connecting with the mooring member 710 of the wind power platform 700, and the operation and maintenance vessel body 100 is used to drive the top support member 110 to move toward the mooring member 710 on the sea surface 300 to connect with the mooring member 710; the rotor device 200 includes a plurality of drive assemblies 210 and a plurality of rotor assemblies 220, and the drive assemblies 210 and the rotor assemblies 220 are connected. 20 are connected in a one-to-one correspondence, a storage cabin 120 is opened on the maintenance ship body 100, and a driving component 210 is arranged in the storage cabin 120; the driving component 210 is configured to drive the corresponding rotor assembly 220 to move when the top support member 110 is docked with the berthing member 710, so that the rotor assembly 220 is extended out of the storage cabin 120; the rotor assembly 220 is configured to drive the maintenance ship body 100 to move when it is extended out of the storage cabin 120, so that the maintenance ship body 100 is out of contact with the sea surface 300.

[0031] Specifically, the top support member 110 is used to dock with the mooring member 710 of the wind power platform 700 to achieve the connection between the operation and maintenance ship and the wind power platform 700, forming a safe transition channel to facilitate the transfer of personnel and materials.

[0032] The rotor assembly 220 is used to provide additional lift during the berthing process of the maintenance ship body 100, so that the maintenance ship body 100 is separated from the sea surface 300 and avoids direct impact of waves on the ship body. In this way, the impact force of waves on the abutment member 110 can be reduced, the stability of the maintenance ship body 100 berthing can be improved, and the service life of the offshore wind power maintenance ship can be extended.

[0033] The storage cabin 120 is used to accommodate the drive assembly 210 and the rotor assembly 220. The drive assembly 210 is used to drive the corresponding rotor assembly 220 to extend out of the storage cabin 120. Through the design of the storage cabin 120, when the rotor assembly 220 is not needed, that is, when the maintenance ship body 100 is traveling normally on the sea surface 300, the drive assembly 210 and the rotor assembly 220 are located in the storage cabin 120. In this way, the maintenance ship body 100 reduces wind resistance and protects the rotor assembly 220 from damage by the external environment. At the same time, the streamlined design of the maintenance ship body 100 is maintained to improve navigation efficiency.

[0034] The embodiment of the present application does not limit the specific type of the drive assembly 210. For example, the drive assembly 210 provided in the storage cabin 120 may be started by a staff member to achieve the purpose of the drive assembly 210 driving the rotor assembly 220 connected thereto to move.

[0035] For example, the driving assembly 210 may include a crank for the staff to hold and operate, the crank is connected to a gear or a pulley, the gear or the pulley is connected to a rotating shaft, and the gear or the pulley is fixed in the storage cabin 120 through a configured wheel frame; in specific implementation, the staff operates the crank to rotate, and the crank drives the gear or the pulley connected thereto to rotate, and then the rotating shaft is driven by a mechanical structure such as a spiral mechanism or a connecting rod mechanism provided thereon, which can convert the rotational motion of the rotating shaft into linear motion, so that the rotor assembly 220 is extended out of the storage cabin 120.

[0036] Alternatively, the drive assembly 210 may also include a manual hydraulic pump and a hydraulic cylinder, the pump body of the manual hydraulic pump is connected to the hydraulic cylinder, the hydraulic cylinder is fixed in the storage cabin 120, and the piston rod of the hydraulic cylinder is connected to the rotor assembly 220; in specific implementation, the staff repeatedly presses the handle of the manual pump to press the hydraulic oil into the hydraulic cylinder, pushes the piston rod to move, and then drives the rotor assembly 220 to extend out of the storage cabin 120. In this way, the drive assembly 210 can provide greater force and more precise control, which is suitable for scenes requiring high thrust.

[0037] Of course, the driving assembly 210 can also be configured as a gear and a rack meshing with the gear, the rack being slidably disposed in the storage compartment 120 through a limiter, wherein the limiter is used to prevent the rack from being out of contact with the storage compartment 120 during sliding, and the rack is connected to the rotor assembly 220; in specific implementation, an operating lever for the staff to hold can be provided on the gear, and the staff rotates the gear to move the rack along a trajectory toward the outside of the storage compartment 120, thereby pushing the rotor assembly 220 to extend out of the storage compartment 120. In this way, the gear-rack structure provides smooth and continuous movement, which can meet the occasions where the moving distance of the rotor assembly 220 needs to be accurately controlled.

[0038] It should be noted that the specific structure of the above-mentioned driving assembly 210 is only given as an example. In actual application, the driving assembly 210 can be set to other structures that can drive the rotor assembly 220 to move, and the embodiment of the present application does not limit this.

[0039] It should also be noted that the structural design of the above-mentioned drive assembly 210 can also operate the drive assembly 210 to further retract the rotor assembly 220 into the storage compartment 120 after the use of the rotor assembly 220. In this way, the functions of the drive assembly 210 are diversified, which facilitates the staff's storage operation of the rotor assembly 220.

[0040] In specific implementation, the driving direction of the maintenance ship body 100 on the sea surface 300 is Figure 2 In the X direction shown, the wind power platform 700 is located on the left side of the operation and maintenance ship body 100. Figure 1The left side of the X direction is the bow, and the right side is the stern; the maintenance ship body 100 has a main cabin 130 above along the Z direction, that is, a cabin for staff to control the movement of the maintenance ship body 100, and a propeller 101 is provided at the stern to provide forward movement of the maintenance ship body 100.

[0041] It is understandable that when the storage cabins 120 are opened on the maintenance ship body 100, the positions and numbers of the storage cabins 120 can be reasonably set to ensure that their distribution does not affect the overall hydrodynamic performance of the hull. For example, the storage cabins 120 can be arranged in areas where the streamline of the hull is less affected, that is, a storage cabin 120 is opened in an area of ​​the maintenance ship body 100 close to the main cabin 130, and the storage cabins 120 are connected to the opposite sides of the maintenance ship body 100, that is, Figure 1 The front and rear sides in the Y direction are shown.

[0042] In this way, on the one hand, a passage can be conveniently set up for the staff to enter and exit between the main cabin 130 and the storage cabin 120 on the maintenance ship body 100. When the top support member 110 is docked with the berthing component 710, the staff can enter the storage cabin 120 through the passage to operate each driving component 210 to start.

[0043] On the other hand, the rotor device 200 disposed in the storage cabin 120 is configured by placing two drive assemblies 210 at a distance at the front side of the storage cabin 120 and two drive assemblies 210 at a distance at the rear side of the storage cabin 120. Then, when the maintenance ship body 100 is moved along the propeller 101, Figure 1 When the vessel moves left in the X direction as shown to dock with the berthing structure 710, the four rotor assemblies 220 are extended out of the storage cabin 120 under the drive of the corresponding drive assemblies 210, and the rotor assemblies 220 are symmetrically arranged on both sides of the maintenance ship body 100. Thus, the staff operates the rotor assemblies 220 to start, and the lift provided by the rotor assemblies 220 to the maintenance ship body 100 can make the maintenance ship body 100 leave the sea surface 300 in a balanced and stable manner.

[0044] In summary, in the offshore wind power operation and maintenance vessel of the embodiment of the present application, when the operation and maintenance vessel body 100 drives the top support member 110 to move toward the berthing member 710 on the sea surface 300, the drive assembly 210 and the rotor assembly 220 are placed in the storage cabin 120 so as to maintain the streamlined design of the operation and maintenance vessel body 100, reduce the resistance during the route, and help improve the navigation efficiency; when the top support member 110 moves to dock with the berthing member 710, the drive assembly 210 is operated to start, so as to use the drive assembly 210 to drive the corresponding rotor assembly 220 to move, so that the rotor assembly 220 is extended out of the storage cabin 120, and then, the rotor assembly 220 is started, and the rotor assembly 220 provides lift for the operation and maintenance vessel body 100, so that the operation and maintenance vessel body 100 is out of contact with the sea surface 300, thereby avoiding the operation and maintenance vessel body 100 from being affected by waves. The offshore wind power operation and maintenance vessel provided by the embodiment of the present application has good berthing stability and small safety hazards.

[0045] In order to facilitate the staff to operate the drive assembly 210 to start, refer to Figure 2 and Figure 3 In some embodiments, the offshore wind power operation and maintenance vessel also includes a first control component 400, the driving assembly 210 includes a driving component 211 and a pushing component 212 connected to the driving component 211, the driving component 211 is fixed in the storage cabin 120, and the pushing component 212 is connected to the corresponding rotor assembly 220; each driving component 211 is communicatively connected to the first control component 400; the first control component 400 is configured to control each driving component 211 to start when the supporting component 110 is docked with the berthing component 710; the driving component 211 is used to drive the corresponding pushing component 212 to move in a direction away from the driving component 211 when starting, so that the pushing component 212 drives the corresponding rotor assembly 220 to extend out of the storage cabin 120.

[0046] Specifically, the drive member 211 and the push member 212 are arranged to realize the precise extension and retraction of the rotor assembly 220. The drive member 211 is used to provide a power source, and the push member 212 is directly connected to the rotor assembly 220 to convert the power of the drive member 211 into the extension and retraction movement of the rotor assembly 220.

[0047] The first control member 400 is used to control the start of the driving member 211 when the top support member 110 is docked with the docking member 710. Exemplarily, the first control member 400 can be a programmable logic controller (PLC), and the PLC is equipped with a control panel for human-computer interaction. In specific implementation, multiple buttons or a touch screen can be set on the control panel, and each button or icon on the screen corresponds to controlling a different driving member 211. By connecting each driving member 211 to the PLC communication, when the staff presses the button on the control panel, the PLC reads the information and performs parsing and logical processing, and then sends the processed instruction to the driving member 211 corresponding to the button, so that the driving member 211 is started to drive the corresponding pushing member 212 to move. In this way, there is no need for the staff to enter and exit the storage cabin 120, saving operation time. It can be understood that the PLC here can be replaced by a microcontroller.

[0048] Alternatively, the first control member 400 can be a wireless remote control, and each driving member 211 is communicatively connected to the wireless remote control. In a specific implementation, the wireless remote control has multiple control axes and buttons for controlling different driving members 211. The staff controls the start and stop of the driving member 211 through buttons, and adjusts the extension and retraction speed and position of the pushing member 212 through the control axis.

[0049] Of course, in order to make the control of the driving component 211 more convenient, in actual application, the maintenance ship body 100 is provided with a detection component for detecting the distance between the top support component 110 and the berthing component 710. When the first control component 400 is a PLC or a microcontroller, the detection component is connected to the PLC for communication. In this way, the PLC reads the sensor data and automatically controls the start-up of the driving component 211 according to the preset program logic, thereby realizing the automatic control of the driving component 210 by the first control component 400.

[0050] It should be noted that, in a specific implementation, the number of the storage compartments 120 can also be set to multiple, and the storage compartments 120 correspond one to one with the driving components 210.

[0051] Further, see Figure 3 The offshore wind power operation and maintenance vessel also includes multiple second control components 500, each of which corresponds to the rotor assembly 220 one by one. The second control component 500 is communicated with the corresponding rotor assembly 220, and each second control component 500 is communicated with the first control component 400; the first control component 400 is used to send a first instruction to each second control component 500 when the pusher 212 drives the corresponding rotor assembly 220 to extend out of the storage cabin 120; the second control component 500 is configured to control the corresponding rotor assembly 220 to start according to the first instruction.

[0052] Specifically, the second control component 500 is used to respond quickly according to the instructions of the first control component 400 and accurately control the rotor assembly 220. The communication connection between the first control component 400 and the second control component 500 and between the second control component 500 and the rotor assembly 220 ensures rapid transmission and feedback of instructions. In this way, the start and stop of each rotor assembly 220 can be achieved without the staff's laborious operation.

[0053] The embodiment of the present application ensures that each rotor assembly 220 can respond to the command of the first control member 400 and realize the synchronous start of the rotor member 223 through the independent control of the second control member 500, thereby improving the accuracy and response speed of the overall control, and at the same time providing a more stable lift for the maintenance ship body 100, ensuring that the maintenance ship body 100 can smoothly leave the sea surface 300. On this basis, in specific implementation, in order to adapt to different sea conditions or load conditions, by setting multiple second control members 500, the second control members 500 correspond to the rotor assembly 220 one by one, so that the second control member 500 can be used to adjust the power output of a single rotor assembly 220 according to the actual situation, thereby improving the operation efficiency.

[0054] The embodiment of the present application does not limit the specific structure of the second control component 500. Exemplarily, the second control component 500 may be one of a microcontroller unit, a digital signal processor, and a programmable logic controller.

[0055] In some embodiments, see Figure 3 and Figure 4 The rotor assembly 220 includes a connecting seat 221, a first motor 222 and a rotor member 223 coaxially connected to the first output shaft of the first motor 222. The first motor 222 is arranged on the connecting seat 221, the connecting seat 221 is connected to the pushing member 212, and the first motor 222 is communicatively connected to the corresponding second control member 500; the second control member 500 is used to control the corresponding first motor 222 to start according to the first instruction, so that the rotor member 223 rotates with the first output shaft to drive the maintenance ship body 100 to break contact with the sea surface 300.

[0056] Specifically, the connecting seat 221 serves as the basic structure of the rotor assembly 220 and is used to fix the first motor 222 , and realizes the movement of the rotor assembly 220 by connecting with the pushing member 212 .

[0057] The first motor 222 is used as a power source. Through its first output shaft, it is coaxially connected to the rotor member 223, and is responsible for driving the rotor member 223 to rotate and generate lift. The second control member 500 is connected to the first motor 222 in communication. According to the first instruction sent by the first control member 400, the first motor 222 is controlled to start, so that the first motor 222 can smoothly drive the rotor member 223 to rotate. Exemplarily, the first motor 222 can provide precise and controllable power output, so that the rotor member 223 can generate sufficient lift as needed, ensuring that the maintenance ship body 100 can smoothly leave the sea surface 300 when docking with the wind power platform 700, reducing the impact of waves.

[0058] The rotor 223 is used to rotate under the drive of the first motor 222 to generate an upward airflow, overcome the impact of gravity and waves, provide necessary lift for the maintenance ship body 100, and make the maintenance ship body 100 break away from contact with the sea surface 300, thereby improving stability during operation.

[0059] In some embodiments, the driving member 211 is a second motor, the pushing member 212 is a push rod, the second motor is communicatively connected to the first control member 400, a transmission part (not shown) is provided on the second output shaft of the second motor, the transmission part is used to move along the axis of the second output shaft when the second output shaft rotates, the push rod is connected to the transmission part, and the push rod is connected to the rotor assembly 220; or, the driving member 211 is a hydraulic oil tank 2111, the pushing member 212 is a hydraulic cylinder 2121, the hydraulic oil tank 2111 includes a tank body 2112 and an electric hydraulic pump 2113, the tank body 2112 is connected to the hydraulic cylinder 2121 via the electric hydraulic pump 2113, the electric hydraulic pump 2113 is communicatively connected to the first control member 400, and the piston rod 2122 of the hydraulic cylinder 2121 is connected to the rotor assembly 220.

[0060] Here, by setting the driving member 211 as the second motor and the pushing member 212 as the push rod, the driving assembly 210 as a whole is used as an electric push rod, which has a simple structure, low maintenance cost and good operation stability, and can meet the working environment that requires frequent extension and retraction of the rotor assembly 220. Among them, the second motor can adjust the moving speed and position of the rotor assembly 220 more accurately according to the instructions of the first control member 400, thereby improving the efficiency and safety of driving the rotor assembly 220 to move.

[0061] Exemplarily, the transmission part may be a screw-nut mechanism or a ball screw mechanism, as long as it can move along the axis of the second output shaft when the second output shaft rotates, and the embodiments of the present application are not limited to this.

[0062] See also Figure 4By setting the driving member 211 as a hydraulic oil tank 2111 and the pushing member 212 as a hydraulic cylinder 2121, the hydraulic drive can meet the needs of the scene where the rotor assembly 220 is heavy and requires high thrust. Among them, the piston rod 2122 of the hydraulic cylinder 2121 can move relatively smoothly, which can reduce the vibration during the extension and retraction process and improve the smoothness and stability of the movement of the rotor assembly 220.

[0063] Considering that when the maintenance ship body 100 is out of contact with the sea surface 300, the maintenance ship body 100 is not affected by the waves and floats, but under the influence of environmental factors such as wind, the maintenance ship body 100 may deviate and shake, thereby affecting the stability when berthing. Therefore, in some examples, refer to Figure 1 The offshore wind power operation and maintenance vessel also includes an inertial measurement device 600, which is arranged on the operation and maintenance vessel body 100; the inertial measurement device 600 is used to detect whether the operation and maintenance vessel body 100 is in a balanced state when the operation and maintenance vessel body 100 is out of contact with the sea surface 300.

[0064] Specifically, the inertial measurement device 600 is used to monitor the posture of the maintenance ship body 100, including the tilt angle, offset, etc. By detecting the posture changes of the maintenance ship body 100, the inertial measurement device 600 can quickly identify the imbalance state of the maintenance ship body 100, thereby providing guidance for the subsequent necessary stabilization measures of the maintenance ship body 100 to protect the safety of personnel and the like.

[0065] In specific implementation, the inertial measurement device 600 can be set as a micro-electromechanical system (MEMS), which integrates a gyroscope, an accelerometer and a magnetometer, and has a small size and low power consumption. Among them, the gyroscope is used to measure the angular velocity, that is, the speed at which an object rotates around an axis. In this way, the gyroscope can detect the rotation of the maintenance ship body 100 around three axes of pitch, roll and yaw; the accelerometer is used to detect the acceleration change of the maintenance ship body 100, which can help determine the tilt angle and vertical movement of the maintenance ship body 100, and assist in stable control.

[0066] For a specific example, see Figure 1 and Figure 5 Each second control component 500 is communicatively connected with the inertial measurement component 600. The inertial measurement component 600 is used to send a second instruction to each second control component 500 when it detects that the maintenance ship body 100 is in an unbalanced state; the second control component 500 is also configured to control the speed and direction of the corresponding first motor 222 according to the second instruction to adjust the posture of the maintenance ship body 100.

[0067] Specifically, the detection data of the inertial measurement component 600 can be used to optimize the control strategy of the second control component 500 on the rotor assembly 220. By setting the second control component 500 to communicate with the inertial measurement component 600, the operation state of the first motor 222 is controlled according to the second instruction sent by the inertial measurement component 600, and the rotor component 223 is precisely controlled. In this way, it is ensured that the maintenance ship body 100 that is out of contact with the sea surface 300 can maintain balance under different wind speeds, wind directions and other environmental conditions, making it more stable to berth.

[0068] Exemplarily, the maintenance ship body 100 is provided with Figure 6 The four rotor components 223 shown are arranged in a rectangular shape, and each rotor component 223 is located at the four vertices of the rectangle. It can be understood that during the rotation of the rotor component 223, a reverse torque opposite to the rotation direction will be generated due to the air resistance. In order to overcome the influence of the reverse torque, two of the four rotor components 223 can be made to rotate forward and two reversely through the second control component 500, wherein the two rotor components 223 located on the diagonal of the rectangle have the same rotation direction.

[0069] The magnitude of the counter torque is related to the rotation speed of the rotor 223. When the rotation speeds of the four rotors 223 are the same, the counter torques generated by the four rotors 223 are balanced, and the maintenance ship body 100 does not rotate. When the rotation speeds of the four propellers 101 are not exactly the same, the unbalanced counter torque will cause the maintenance ship to rotate. Figure 7 When the Z axis is rotated in one direction, the direction of rotation is Figure 7 The two rotors 223 in the X direction shown have the same direction of rotation. The rotation speed of the two rotors 223 in the X direction is increased and the rotation speed of the two rotors 223 in the Y direction is decreased by the second control member 500, wherein the rotating arrow indicates the direction of rotation, the upper arrow indicates the increase of the rotation speed, and the lower arrow indicates the decrease of the rotation speed; the counter-torque of the two rotors 223 in the X direction on the maintenance ship body 100 is greater than the counter-torque of the two rotors 223 in the Y direction on the maintenance ship body 100, and the maintenance ship body 100 overcomes the effect of the wind force under the effect of the surplus counter-torque and rotates in the opposite direction around the z-axis, wherein the direction of the reverse rotation is opposite to the direction of the two rotors 223 in the X direction.

[0070] Furthermore, when the maintenance ship 100 is berthed to allow staff to board the wind turbine platform 700, the maintenance ship 100 may become unbalanced due to the movement of staff or the transport of equipment, causing the maintenance ship 100 to separate from the sea surface 300 and move along the sea surface 300. Figure 8 The Y direction pitch rotation shown in the figure is controlled by the second control member 500 Figure 8 One of the two rotor members 223 in the X direction shown in the figure has a rotation speed that increases, while the other has a rotation speed that decreases, wherein the rotation speed changes of the two are equal in magnitude. Figure 8 The rotating arrow in the figure indicates the direction of rotation, the upward arrow indicates the increase of the rotation speed, and the downward arrow indicates the decrease of the rotation speed; the rotation speed of the two rotor members 223 in the Y direction remains unchanged. In this way, the unbalanced torque generated by the change of the rotation speed of the two rotor members 223 in the X direction causes the maintenance ship body 100 to overcome the imbalance of gravity and rotate in the opposite direction, thereby achieving the balance of the maintenance ship body 100.

[0071] For specific implementation, see Figure 1 and Fig. 9 The storage cabin 120 has a storage cavity 121 with an opening 122 on one side. The driving assembly 210 is arranged in the corresponding storage cavity 121. The storage cabin 120 is movably connected with a cabin door 123; the cabin door 123 is configured to move relative to the storage cabin 120 before the driving assembly 210 moves to drive the corresponding rotor assembly 220 to move, so as to open the opening 122 and form an avoidance channel for the rotor assembly 220 to extend out of the storage cabin 120.

[0072] Here, by providing a hatch 123, the hatch 123 is movably connected to the storage cabin 120, and is used to open the opening 122 of the storage cabin 120 when the rotor assembly 220 needs to be extended, providing an escape channel for the rotor assembly 220, and ensuring that it can be smoothly extended out of the storage cabin 120. Such a design not only ensures the streamlined design of the hull during navigation, but also enables the storage cabin 120 to be quickly opened when necessary, providing convenience for the extension of the rotor assembly 220; in addition, the movable connection design of the hatch 123 is also convenient for maintenance and inspection, and improves the overall maintainability.

[0073] The embodiment of the present application does not limit the connection method between the hatch 123 and the storage cabin 120, as long as the hatch 123 can move relative to the storage cabin 120 to open the opening 122. For example, the bulkhead of the storage cabin 120 is provided with a slide groove extending toward the maintenance ship body 100, part of the hatch 123 is slidably set in the slide groove, and the other part of the hatch 123 is exposed in the slide groove and closes the opening 122. In this way, the staff applies a thrust toward the slide groove to the hatch 123 to slide the hatch 123 relative to the storage cabin 120, and slides the other part of the hatch 123 into the slide groove to open the opening 122; or, the hatch 123 can also be hinged on the storage cabin 120, and the staff applies a pulling force to the hatch 123 to rotate the hatch 123 relative to the storage cabin 120 to open the opening 122.

[0074] In specific implementation, on the basis of setting the first control component 400, the cabin door 123 can be set as a control door that wirelessly communicates with the first control component 400. Before the first control component 400 controls each driving component 211 to start, that is, before the driving assembly 210 moves to drive the corresponding rotor assembly 220 to move, the first control component 400 first controls the cabin door 123 to open the opening 122 to form an avoidance channel for the rotor assembly 220 to extend out of the storage cabin 120.

[0075] Continue reading Fig. 9 In some embodiments, the rotor assembly 220 further includes an air deflector 224 , and the air deflector 224 is disposed on the rotor member 223 .

[0076] By providing the air deflector 224, the air deflector 224 can guide the airflow to flow through the rotor member 223 more effectively, reduce the generation of turbulence and eddy currents, thereby increasing the ratio of the lift generated by the rotor member 223 to the required power and reducing energy consumption.

[0077] In addition, the air deflector 224 can improve the airflow distribution around the rotor 223, reduce the impact of airflow disturbance caused by sea breeze on the performance of the rotor 223, and improve the stability of the maintenance ship body 100.

[0078] In a specific example, the supporting member 110 is a rubber pad, or the supporting member 110 is a tire.

[0079] By setting the top support member 110 as a rubber pad, the rubber pad has good elasticity and can absorb the impact force when the operation and maintenance ship body 100 and the mooring component 710 are docked, reduce vibration, and protect the structure of the operation and maintenance ship body 100 and the mooring component 710; the rubber material can provide sufficient friction to prevent the operation and maintenance ship body 100 from sliding relative to the wind power platform 700 in wet or wavy conditions, thereby improving stability during docking; the rubber pad is easy to replace and maintain, reducing the difficulty and cost of maintenance.

[0080] By setting the supporting member 110 as a tire and the adjustable inflation volume inside the tire, the supporting force can be adjusted according to the actual situation to adapt to different sea conditions and docking requirements; the circular structure of the tire makes it adaptable when the contact surface is not completely flat, maintaining stable contact with the berthing member 710 and improving the reliability of the supporting.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
