Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a modular power unit for an open container ship. Background Art

[0002] Open-top container ships are hatchless container ships designed to transport containers and facilitate loading and unloading, effectively improving loading and unloading efficiency. Conventional open-top container ships mostly use diesel generators for power generation. To meet the demands of shipping, these generators are extremely large, not only limiting vessel space but also making them difficult to replace if damaged, leading to delays in shipping operations. Utility Model Content

[0003] The purpose of the utility model is to provide a modular power unit for an open container ship, wherein the power unit module adopts a gas generator to burn LNG to generate electricity, and the power unit is modularly designed and can be detachably installed on the main deck. When the power unit module is damaged, the entire module can be directly disassembled, hoisted and replaced, thereby effectively improving the replacement efficiency of the power unit module and avoiding affecting the transportation and navigation of the ship.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A modular power unit for an open container ship, comprising at least three groups of power unit modules arranged in parallel along the width direction of the hull, each group of power unit modules being arranged along the length direction of the hull and being fixed to the main deck of the hull via a detachable mounting structure;

[0006] Each group of power unit modules includes a box arranged along its length, with lifting rings provided at the four corners of the top of the box, at least three gas generators arranged in an array along its length inside the box, and a plurality of double doors corresponding to the gas generators on one side wall along its length; a first connector, a second connector, and a third connector are provided on the side wall of the box, and the first connector, the second connector, and the third connector are respectively connected to the three gas generators through pipes; a power output unit connected to the gas generator is provided at one end of the box, and the power output unit is connected to an output connector provided on the outside of the side wall of the box;

[0007] The detachable mounting structure includes longitudinal fixing bars arranged at both ends of the box body along the width direction of the box body, the longitudinal fixing bars are fixed on the main deck, the bottom of the box body is provided with a base integrally formed therewith, and the bottom ends of the base are provided with longitudinal fixing grooves that cooperate with the longitudinal fixing bars; the two side walls of the base along its length direction are provided with transverse fixing grooves arranged along its length direction, and a transverse fixing bar that cooperates with the transverse fixing groove is installed between the two longitudinal fixing bars; when the power unit module is installed on the main deck, the longitudinal fixing bar is clamped in the corresponding longitudinal fixing groove, and the transverse fixing bar is clamped in the corresponding transverse fixing groove and fixed on the longitudinal fixing bar.

[0008] By adopting the above technical solution, multiple groups of power unit modules are fixed to the main deck of the hull through a detachable mounting structure. The longitudinal fixing bars are clamped in the corresponding longitudinal fixing grooves to achieve horizontal and perpendicular positioning of the power unit modules in the length direction of the longitudinal fixing bars. The transverse fixing bars are clamped in the corresponding transverse fixing grooves to achieve vertical positioning of the power unit modules. The transverse fixing bars are fixed to the longitudinal fixing bars. The transverse fixing bars on both sides of the power unit modules cooperate to achieve positioning of the power unit modules along the length direction of the longitudinal fixing bars, thereby achieving fixed installation of the power unit modules. When working, multiple gas generators are connected to the external LNG fuel tank box through the first connector, the second connector and the third connector and the corresponding pipelines to achieve LNG fuel supply to the gas generators. The multiple gas generators in each group of power unit modules work simultaneously to generate electricity through combustion, and transmit the electricity generated by combustion to the battery through the power output unit and the output connector for ship propulsion or daily electricity use.

[0009] When a power unit module fails, disconnect its first connector, second connector, third connector and output connector from the outside, release the connection between the horizontal and vertical fixing bars, remove the horizontal fixing bars from the corresponding horizontal fixing grooves, connect the external lifting equipment to the lifting ring on the corresponding power unit module, and then the failed power unit module can be lifted and removed as a whole and replaced with a workable power unit module.

[0010] In the present invention, multiple groups of power unit modules are directly fixed on the main deck of the hull through a detachable mounting structure. Multiple gas generators that burn LNG are used in the power unit modules to generate electricity. The design of the modules and the special detachable mounting structure make it possible to quickly release the fixation of the power unit modules by simply disconnecting the connection with the outside and removing the cross-fixing bars when a power unit module fails. The modules can then be directly hoisted and replaced as a whole without having to troubleshoot the fault points one by one and then repair them. This greatly improves the replacement efficiency of the power unit modules and avoids delays in the ship's navigation and transportation time.

[0011] Furthermore, the upper end surface of the longitudinal fixing bar is provided with a locking groove arranged along its length direction, and the side of the transverse fixing bars at both ends of the longitudinal fixing bar away from each other is respectively provided with locking blocks integrally formed with them and slidably installed in the locking groove; a locking screw arranged along its length direction is positioned and rotatably installed in the locking groove, the two locking blocks are threadedly connected to the locking screw and the thread rotation directions are opposite, and one end of the locking screw is connected to a locking motor that drives it to rotate.

[0012] By adopting the above technical solution, the locking motor drives the locking screw to rotate. Under the limiting and guiding effect of the locking groove on the locking block, and the threaded connection between the locking screw and the two locking blocks with opposite rotation directions, the two locking blocks are driven to cause the two cross-fixing bars to slide synchronously towards or away from each other, and the cross-fixing bars are automatically driven into or out of the corresponding cross-fixing grooves, quickly securing or releasing the power unit module. The use of a screw drive method to adjust and secure the position of the cross-fixing bar eliminates the need for additional screw fixing operations, greatly improving operation speed. It can also secure power unit modules of different widths, effectively expanding the scope of application.

[0013] Furthermore, positioning rings with vertical axes are provided at both ends of the base, and the axes of the positioning rings are located on the symmetry plane of the two locking blocks; the side walls of the longitudinal reinforcement strips are provided with connecting rods perpendicular to them, and the end of the connecting rod away from the longitudinal reinforcement strip is provided with a vertically arranged positioning rod that cooperates with the positioning ring, and the bottom of the box body is provided with a yield groove that cooperates with the connecting rod and is connected to the longitudinal reinforcement groove.

[0014] By adopting the above technical solution, when hoisting the power unit module, the positioning rod and the positioning ring are aligned so that the longitudinal fixing bar is inserted into the longitudinal fixing groove, and the positioning rod is inserted into the corresponding positioning ring. The axis of the positioning ring is located on the symmetrical plane of the two locking blocks. The positioning rod and the positioning ring are coordinated to achieve the positioning installation of the power unit module, ensuring that when the two transverse fixing bars are driven to slide synchronously close to each other, the two transverse fixing bars can be smoothly inserted into the corresponding transverse fixing grooves, thereby ensuring the fixed installation effect of the power unit module.

[0015] Furthermore, ventilation holes are provided at both ends of the box body, and blinds are installed in the ventilation holes. The blinds are connected to an adjustment mechanism that drives the adjustment of the ventilation area of ​​the ventilation holes. Multiple thermometers are evenly arranged in the box body, and the thermometers are connected to the adjustment mechanism for communication feedback control.

[0016] By adopting the above technical solution, multiple thermometers detect the temperature inside the box in real time. When the temperature inside the box is too high, the feedback control adjustment mechanism drives the blinds to work and adjust the ventilation area of ​​the vents to dissipate heat from the box, while preventing the vents from always maintaining a large area of ​​ventilation. In bad weather conditions, foreign matter or rainwater can easily enter the box through the vents.

[0017] Furthermore, the venetian blind includes a rectangular frame fixedly installed in the vent, and a plurality of blades arranged along the width direction of the box are arranged in an array from top to bottom in the rectangular frame; both ends of the blades are provided with rotating shafts whose axes are arranged along their length direction and are positioned and rotatably installed on the rectangular frame, and the adjusting mechanism drives the plurality of rotating shafts to drive the corresponding blades to rotate; when the blades rotate to a vertical state, the ventilation area of ​​the vent is minimized, and when the blades rotate to a horizontal state, the ventilation area of ​​the vent is maximized.

[0018] By adopting the above technical solution, the adjustment mechanism drives the shaft to rotate the blades, adjusting the blades' tilt angle, and thus adjusting the distance between adjacent blades to adjust the ventilation area of ​​the vent. When the blades are rotated to a vertical position, the ventilation area of ​​the vent is minimized, while when the blades are rotated to a horizontal position, the ventilation area of ​​the vent is maximized. The ventilation area can be adjusted to the appropriate size based on the temperature inside the box fed back by the thermometer, ensuring effective ventilation and heat dissipation while preventing foreign matter and rainwater from entering the box and affecting the service life of the internal components.

[0019] Furthermore, the adjustment mechanism includes several rotating gears installed on corresponding rotating shafts, and the rotating gears are coaxially arranged with the corresponding rotating shafts; the inner wall of the rectangular frame is provided with an adjustment rack vertically arranged and meshed with several rotating gears, and the adjustment rack is vertically slidably installed in the rectangular frame and is located on the side of the rotating gear close to the box body; the rectangular frame also positions and rotatably installs an adjustment gear that meshes with the adjustment rack and is located on the side of the adjustment rack away from the rotating gear, and the adjustment gear is connected to an adjustment motor that drives it to rotate, and several of the thermometers are connected to the adjustment motor for communication feedback control.

[0020] By adopting the above technical solution, the thermometer controls the operation of the regulating motor according to the real-time temperature detected by it through communication feedback, and the regulating motor drives the regulating gear to rotate. Under the meshing action of the regulating gear and the regulating rack, the regulating rack is driven to slide vertically. Under the meshing action of the regulating rack and several rotating gears, several rotating gears are driven to drive the corresponding rotating shafts to rotate, thereby driving several blades to rotate and adjusting the ventilation area of ​​the vent. The structure is simple, easy to operate and has obvious effects.

[0021] Furthermore, a vertically arranged shielding strip is provided on the outside of the rectangular frame and is located at both ends of the blade. The shielding strip is an L-shaped structure with its opening facing the rotating gear, and several rotating gears located on the same side are located in the opening of the corresponding shielding strip; the upper end and bottom end of the shielding strip abut against the inner top wall and inner bottom wall of the rectangular frame, and the two ends of the blade abut against the side wall close to the shielding strip.

[0022] By adopting the above technical solution, the shielding strip is in an L-shaped structure with its opening facing the rotating gear, the upper and lower ends abut against the top wall and the inner bottom wall of the rectangular frame, the two ends of the blade abut against the side walls close to the shielding strip, and the rotating gear is located in the opening of the shielding strip. In this way, the shielding strip is used to protect the rotating gear to avoid direct exposure of the rotating gear, which is prone to rust under harsh navigation conditions for a long time, affecting the normal engagement of the rotating gear and the adjustment rack, and affecting the adjustment of the ventilation area of ​​the vent.

[0023] Furthermore, a cooling fan near the ventilation port is installed inside the box, and the thermometer is connected to the cooling fan for communication feedback control; a plurality of raindrop sensors are installed outside the box, and the raindrop sensors are connected to the cooling fan and the regulating mechanism for communication feedback control.

[0024] By adopting the above technical solution, when the temperature inside the box detected by the thermometer is too high, the cooling fan can be controlled by communication feedback, and the ventilation area of ​​the vents can be adjusted to increase the air flow speed inside the box to improve heat dissipation efficiency. A raindrop sensor is used to detect the amount of rain outside the box. If the rainfall is too heavy, the adjustment mechanism can be controlled by communication feedback to drive the blinds to reduce the ventilation area of ​​the vents. Communication feedback is also used to control the operation of the cooling fan. The cooperation between the cooling fan and the vents ensures effective heat dissipation while preventing rain from entering the box through the vents.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. In the present invention, multiple power unit modules are directly fixed on the main deck of the ship through a detachable mounting structure. The power unit modules use multiple LNG-burning gas generators to generate electricity. The module design and special detachable mounting structure ensure that when a power unit module fails, the module can be quickly released by simply disconnecting the external connection and removing the cross-fixing bar. The module can then be directly hoisted and replaced as a whole, eliminating the need to sequentially troubleshoot the fault points for repair. This greatly improves the efficiency of power unit module replacement and avoids delays in the ship's navigation and transportation time.

[0027] 2. In the present invention, the locking groove, locking block, locking screw, locking motor and other structures are used to drive the cross-fixing bar to automatically snap into or out of the corresponding cross-fixing groove, quickly fixing or releasing the power unit module without the need for additional screw fixing operations, greatly improving the operating speed. It can also fix power unit modules of different widths, effectively expanding the scope of application.

[0028] 3. In the utility model, vents are set at both ends of the box body, and the adjustment mechanism is used to drive the blinds to adjust the ventilation area of ​​the vents. A thermometer, a cooling fan, a raindrop sensor, etc. are also provided. While achieving heat dissipation of the box body, it also prevents the vents from always maintaining a large area of ​​ventilation. In bad weather conditions, foreign matter or rainwater can easily enter the box through the vents. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] A modular power unit for an open container ship, such as Figure 1As shown, it includes at least three groups of power unit modules 2 arranged in parallel along the width of the hull. Each group of power unit modules 2 is arranged along the length of the hull and is fixed to the main deck 1 of the hull via a detachable mounting structure 3. In this embodiment, three groups of power unit modules 2 are provided. In other embodiments, the number of power unit modules 2 can be selected according to actual usage requirements.

[0036] like Figure 1 and Figure 2 As shown, each power unit module 2 includes a housing 21 extending along its length. Within housing 21, at least three gas generators 22 are arrayed along its length. A first connector 24, a second connector 25, and a third connector 26 are provided on the sidewalls of housing 21. These connectors are each connected to the three gas generators 22 via pipes 221. These connectors are used to connect to external LNG fuel tanks, thereby supplying LNG fuel to the multiple gas generators 22. A power output unit 27 connected to all gas generators 22 is provided at a corner of one end of housing 21. This power output unit 27 is connected to an output connector 271 provided on the outside of the sidewalls of housing 21. This output connector 271 is used to connect to a battery.

[0037] like Figure 2 As shown, in this embodiment, each power unit module 2 is equipped with three gas generators 22. These three gas generators 22 operate simultaneously, burning LNG fuel to generate electricity. The generated electricity is then stored in a battery via a power output unit 27 and an output connector 271 for use in the propulsion system or daily electricity consumption. The structure and operating principle of the gas generators 22 are similar to those in the prior art and are only briefly illustrated in the figure. Of course, in other embodiments, the number of gas generators 22 can be increased based on actual usage requirements.

[0038] Among them, such as Figure 2 As shown, one of the longitudinal side walls of the box 21 is provided with multiple sets of bi-directional doors 23 corresponding to the gas generators 22. The specific structure of the bi-directional doors 23 is the same as that of the prior art, and is mainly used to close the box 21 under normal conditions and to open the box 21 when maintaining the equipment inside the box 21. In addition, there are lifting rings 211 at the four corners of the top of the box 21, which are connected to external equipment such as cranes through the lifting rings 211 to facilitate lifting and moving the box 21.

[0039] In this embodiment, if Figure 2 and Figure 3As shown, the detachable mounting structure 3 includes longitudinal reinforcement bars 31 arranged at both ends of the box body 21 along the width direction of the box body 21. The longitudinal reinforcement bars 31 are fixed to the main deck 1 by welding or screwing. A base 28 is integrally formed at the bottom of the box body 21, and longitudinal reinforcement grooves 281 are provided at both ends of the bottom of the base 28 to cooperate with the longitudinal reinforcement bars 31. Horizontal reinforcement grooves 282 are provided along the length of the two side walls of the base 28. A horizontal reinforcement bar 32 is installed between the two longitudinal reinforcement bars 31 to cooperate with the horizontal reinforcement grooves 282.

[0040] like Figure 1 and Figure 3 As shown, when the power unit module 2 is installed on the main deck 1, the longitudinal fixing bar 31 is clamped in the corresponding longitudinal fixing groove 281 to realize the horizontal limit fixation of the power unit module 2 perpendicular to the length direction of the longitudinal fixing bar 31, and the transverse fixing bar 32 is clamped in the corresponding transverse fixing groove 282 and fixed on the longitudinal fixing bar 31 to realize the vertical limit fixation of the power unit module 2 and the limit fixation along the length direction of the longitudinal fixing bar 31, thereby realizing the fixed installation of the power unit module 2.

[0041] like Figure 2 and Figure 3 As shown, to further improve the efficiency of rapid assembly and disassembly of the power unit module 2 by the detachable mounting structure 3, in this embodiment, a locking groove 311 is provided on the upper end surface of the longitudinal fixing bar 31 along its length. Locking blocks 321 are provided on the sides of the transverse fixing bars 32 at both ends of the longitudinal fixing bar 31, which are formed integrally with the longitudinal fixing bar 31 and slidably mounted within the locking groove 311. A locking screw 33, which is arranged along its length, is positioned and rotatably mounted within the locking groove 311. Two locking blocks 321 are threadedly connected to the locking screw 33, and their threads rotate in opposite directions. One end of the locking screw 33 is connected to a locking motor 34 that drives its rotation.

[0042] like Figure 2 and Figure 3 As shown, the locking motor 34 drives the locking screw 33 to rotate, thereby driving the two locking blocks 321 to drive the two cross-fixing bars 32 to slide synchronously towards or away from each other, thereby driving the two cross-fixing bars 32 to automatically snap into or move out of the corresponding cross-fixing grooves 282, quickly fixing or releasing the power unit module 2. Not only does it not require additional screw fixing operations, it greatly improves the operating speed, but it can also fix power unit modules 2 of different widths, effectively improving the scope of application.

[0043] Among them, such as Figure 2 and Figure 3As shown, to ensure that the two transverse fixing bars 32 can be simultaneously inserted into the transverse fixing grooves 282, positioning rings 283 with vertical axes are provided at both ends of the base 28. The axes of the positioning rings 283 are located on the symmetrical planes of the two locking blocks 321. A connecting rod 35 perpendicular to the longitudinal fixing bar 31 is provided on the side wall thereof. A positioning rod 36 vertically arranged and cooperating with the positioning ring 283 is provided at the end of the connecting rod 35 away from the longitudinal fixing bar 31. A clearance groove 284 cooperating with the connecting rod 35 and communicating with the longitudinal fixing groove 281 is provided at the bottom of the box body 21. When hoisting the power unit module 2, the positioning rod 36 and the positioning ring 283 are aligned so that the longitudinal fixing bar 31 is inserted into the longitudinal fixing groove 281, the positioning rod 36 is inserted into the corresponding positioning ring 283, and the connecting rod 35 is inserted into the clearance groove 284, thereby achieving the positioning installation of the power unit module 2 and ensuring the fixed installation effect of the power unit module 2.

[0044] like Figure 2 and Figure 4 As shown, to achieve heat dissipation of the power module unit, vents 4 are provided at both ends of the housing 21. Venetian blinds 5 are installed within the vents 4. Venetian blinds 5 are connected to an adjustment mechanism 6 that drives them to adjust the ventilation area of ​​the vents 4. Multiple thermometers 7 are evenly distributed within the housing 21 and communicate with the adjustment mechanism 6 for feedback control. Specifically, the vents 5 include a rectangular frame 51 fixedly mounted within the vents 4. Within the rectangular frame 51, a plurality of blades 52 are arranged in an array from top to bottom along the width of the housing 21. At each end of the blades 52 are shafts 53 with axes extending along their lengths and rotatably mounted on the rectangular frame 51. The adjustment mechanism 6 drives the shafts 53 to rotate the corresponding blades 52. When the blades 52 are rotated to a vertical position, the ventilation area of ​​the vent 4 is minimized. When the blades 52 are rotated to a horizontal position, the ventilation area of ​​the vent 4 is maximized.

[0045] like Figure 4 As shown, the adjustment mechanism 6 includes a plurality of rotating gears 54 mounted on corresponding rotating shafts 53, and the rotating gears 54 are coaxially arranged with the corresponding rotating shafts 53; an adjustment rack 61 is vertically arranged and meshed with the plurality of rotating gears 54 on the inner wall of the rectangular frame 51, and the adjustment rack 61 is vertically slidably mounted in the rectangular frame 51 and is located on the side of the rotating gear 54 close to the inside of the box 21. An adjustment gear 62 is also positioned and rotatably mounted in the rectangular frame 51 and meshed with the adjustment rack 61 and located on the side of the adjustment rack 61 away from the rotating gear 54. The adjustment gear 62 is connected to an adjustment motor 63 that drives it to rotate. A plurality of thermometers 7 (marked on Figure 2 Middle) is connected to the regulating motor 63 for communication feedback control.

[0046] like Figure 2 and Figure 4As shown, the thermometer 7 controls the adjustment motor 63 to work according to the real-time temperature detected by it through communication feedback. The adjustment motor 63 drives the adjustment gear 62 to rotate. Under the meshing action of the adjustment gear 62 and the adjustment rack 61, the adjustment rack 61 is driven to slide vertically. Under the meshing action of the adjustment rack 61 and the plurality of rotating gears 54, the plurality of rotating gears 54 are driven to drive the corresponding rotating shafts 53 to rotate, thereby driving the plurality of blades 52 to rotate and adjusting the inclination angle of the blades 52. The ventilation area of ​​the vent 4 can be adjusted by adjusting the distance between adjacent blades 52. While ensuring the heat dissipation effect of the box body 21, it also avoids the ventilation area of ​​the vent 4 being too large, which may cause foreign matter or rainwater to easily enter the box body 21 through the vent 4 under bad weather conditions.

[0047] Among them, such as Figure 3 and Figure 4 As shown, vertical shielding bars 55 are provided on the outside of the rectangular frame 51, located at both ends of the blades 52. The shielding bars 55 are L-shaped, with their openings facing the rotating gears 54. Several rotating gears 54 on the same side are located within the openings of the corresponding shielding bars 55. The top and bottom of the shielding bars 55 abut against the inner top and bottom walls of the rectangular frame 51, while the ends of the blades 52 abut against the side walls adjacent to the shielding bars 55. This shielding bar 55 protects the rotating gears 54, preventing them from being directly exposed, which could easily rust under harsh navigation conditions over time, affecting the proper meshing of the rotating gears 54 and the adjustment rack 61, and thus affecting the adjustment of the ventilation area of ​​the vent 4.

[0048] In this embodiment, if Figure 2 and Figure 4 As shown, cooling fans 8 are installed at both ends of the housing 21 near the vents 4. A thermometer 7 is connected to the cooling fans 8 for communication feedback control. When the internal temperature of the housing 21, as detected by the thermometer 7, is too high, the cooling fans 8 are activated through communication feedback control. This, in conjunction with the adjustment of the ventilation area of ​​the vents 4, accelerates the air flow rate within the housing 21, thereby improving heat dissipation efficiency. Raindrop sensors 9 are installed on the top of the housing 21 and on both sides of the housing 21 where the vents 4 are located. The raindrop sensors 9 are connected to the cooling fans 8 and the regulating mechanism 6 for communication feedback control. The raindrop sensors 9 detect the amount of rainfall outside the housing 21. If the rainfall is too heavy, the regulating mechanism 6 is controlled through communication feedback control to drive the blinds 5 to reduce the ventilation area of ​​the vents 4 and to control the cooling fans 8 for communication feedback control. The coordination between the cooling fans 8 and the vents 4 ensures effective heat dissipation while preventing rainwater from entering the housing 21 through the vents 4.

[0049] The working principle and usage of this utility model:

[0050] Multiple groups of power unit modules 2 are fixed to the main deck 1 of the hull through a detachable mounting structure 3, the positioning rod 36 is inserted into the positioning ring 283, the longitudinal fixing bar 31 is clamped in the corresponding longitudinal fixing groove 281, and the transverse fixing bar 32 is clamped in the corresponding transverse fixing groove 282 to achieve fixed installation of the power unit module 2.

[0051] During operation, multiple gas generators 22 are connected to the external LNG fuel tank through the first connector 24, the second connector 25 and the third connector 26 and the corresponding pipeline 221. Multiple gas generators 22 work simultaneously to generate electricity through combustion, and transmit the electricity generated by combustion to the battery through the power output unit 27 and the output connector 271 for ship propulsion or daily electricity use.

[0052] According to the temperature inside the box 21 detected in real time by the thermometer 7 and the amount of rainfall detected in real time by the raindrop sensor 9, the control regulating mechanism 6 adjusts the ventilation area of ​​the vent 4 and cooperates with the cooling fan 8 to achieve heat dissipation of the box 21.

[0053] When a power unit module 2 fails, disconnect the first connector 24, the second connector 25, the third connector 26 and the output connector 271 from the outside, start the locking motor 34 to drive the two cross-fixing bars 32 to slide away from each other and out of the cross-fixing groove 282, release the limiting cooperation between the cross-fixing bars 32 and the cross-fixing groove 282, and connect the external lifting equipment to the lifting ring 211 on the corresponding power unit module 2. Then, the faulty power unit module 2 can be lifted and removed as a whole, and replaced with a workable power unit module 2.

[0054] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
