Description

Technical Field

[0001] This application relates to the field of marine power generation equipment technology, and in particular to a small, easy-to-maintain marine silent generator set. Background Technology

[0002] With the development of the shipping industry and the increasing demands for the quality of life of crew members, the control of operating noise of ship generator sets is becoming increasingly stringent.

[0003] In related technologies, existing marine silent generator sets typically consist of a sealed metal casing enclosing the engine and generator, filled with sound-absorbing cotton, and equipped with intake and exhaust silencers to reduce noise. However, in practical applications, to achieve ideal noise reduction targets and solve the unit's own heat dissipation problems, the design of traditional silent casings tends to be conservative and bulky. Currently, most products on the market use an integral welded structure or multiple panels fixed together with dense bolts. While this traditional structure ensures a certain degree of sealing and noise reduction, its structural defects gradually become apparent under the limited space and severe rolling and vibration conditions of ships. Especially when the equipment requires regular maintenance after long-term operation, the need to disassemble a large number of panels makes the existing casing structure a huge obstacle, resulting in high maintenance costs and long downtime, seriously affecting the normal operating efficiency of the ship. Summary of the Invention

[0004] This application provides a small, easy-to-maintain marine silent generator set, which aims to significantly improve the maintenance efficiency of the generator set. After the entire silent casing of the generator set is removed, key components such as the engine, generator and radiator can be completely exposed, allowing technicians to directly perform operations such as hoisting and replacing parts without having to work in a confined space.

[0005] This application provides a small, easy-to-maintain marine silent generator set, which adopts the following technical solution: A small, easy-to-maintain marine silent generator set includes a chassis, which consists of a silent outer shell and a base. The silent outer shell covers the top of the base, and an inspection door is provided on the side of the silent outer shell. A self-locking mechanism is provided between the silent outer shell and the base. The self-locking mechanism includes a locking rod and a locking seat. The locking rod is connected to the bottom of the silent outer shell, and the locking seat is located on the top of the base. The locking rod and the locking seat are engaged and connected.

[0006] By adopting the above technical solution, this configuration replaces the traditional method of fixing with a large number of bolts by using a self-locking mechanism consisting of a locking rod and a locking seat. This snap-fit ​​connection method enables quick installation and removal between the silent housing and the base, significantly shortening the unit's assembly and disassembly time. When deep maintenance is required, the housing can be quickly removed as a whole, eliminating the tedious screw-tightening operation, thereby significantly improving the maintenance efficiency of the generator set.

[0007] This design also allows for the complete removal of the soundproof enclosure, exposing critical components such as the engine, generator, and radiator. This completely breaks the limitations imposed by the narrow space inside traditional soundproof enclosures on maintenance work, allowing technicians to directly lift and replace parts on the unit without having to work in a confined space. This not only improves the convenience of operation but also enhances the safety and accuracy of the maintenance process.

[0008] Preferably, the locking rod has a slot along its length, and two locking members are provided in the slot. The two locking members are distributed on the left and right sides of the slot. The two locking members slide horizontally toward each other or away from each other. The top of the locking seat is integrally connected to a locking seat, and the locking seat and the two locking members are locked together.

[0009] By adopting the above technical solution, the locking rod and the locking seat are locked together using the locking seat and two locking parts, thereby achieving the locking between the silent shell and the base.

[0010] Preferably, the end of the clamping member near the clamping seat is wedge-shaped, and the clamping seat is semi-circular in shape. The clamping seat is used to drive the two clamping members to slide in a direction away from each other.

[0011] By adopting the above technical solution, during specific assembly, a hoisting machine is used to lift the silent shell, and the locking rod at the bottom of the silent shell is aligned with the corresponding locking seat. Then, the silent shell is lowered; as it continues to descend, the locking seat enters the locking groove, at which point the locking element is positioned above the locking seat.

[0012] As the mute housing continues to descend, when the clamping members abut against the top of the clamping seat, due to the wedge-shaped ends of the clamping members, the clamping seat drives the two clamping members to slide away from each other as the mute housing continues to descend. Then, as the mute housing continues to descend, when the two clamping members reach below the clamping seat, they slide towards each other.

[0013] At this point, the two clamping parts are locked at the bottom of the clamping seat. The cylinder then pushes the silent shell upwards. The clamping seat is fixed to the ground by fastening bolts. The cylinder pushes the silent shell upwards, so that the clamping parts and the clamping seat can always remain locked.

[0014] Preferably, a limiting groove is formed in the locking rod along the horizontal direction, the clamping member is slidably installed in the limiting groove along the horizontal direction, and a return spring is provided in the limiting groove.

[0015] By adopting the above technical solution, a return spring is used to make the two clamping parts slide towards each other or away from each other. When the two clamping parts slide away from each other, the clamping parts compress the return spring. When the two clamping parts descend below the clamping seat, the return spring releases its elastic force and drives the two clamping parts to slide towards each other.

[0016] Preferably, the bottom of the clamping seat is provided with a first movable groove, which is used to allow the two clamping members to slide toward the clamping seat.

[0017] By adopting the above technical solution, when the two clamping parts descend to below the clamping seat, the reset spring drives the two clamping parts to slide in the first movable groove until the two clamping parts are locked under the clamping seat.

[0018] Preferably, the bottom of the clamping seat is provided with a sliding member, which is used to drive the two clamping members to slide in a direction away from each other. The sliding member slides in a direction closer to or away from the clamping seat, and the process of the sliding member sliding closer to the clamping seat completes the unlocking between the clamping members and the clamping seat.

[0019] Specifically, by adopting the above technical solution, when unlocking the silent shell and base, the cylinder is removed, and the silent shell is hoisted using a hoisting machine. The silent shell is lowered by the hoisting machine, and simultaneously, the locking rod is lowered, which in turn lowers the clamping components. When the clamping components descend to the sliding components, the sliding components drive the two clamping components to slide away from each other. In this state, the clamping components compress the return spring.

[0020] As the clamping components continue to descend, the return spring releases its force, causing the two clamping components to slide closer to each other, and driving the sliding component to slide closer to the clamping seat. Subsequently, the hoisting machine begins to rise, causing the silent housing to rise as well. At this time, the sliding component unlocks the clamping components and the clamping seat as it slides closer to the clamping seat.

[0021] Preferably, the slider is cone-shaped.

[0022] By adopting the above technical solution, the sliding member is made into a cone shape with a cone surface on its periphery. When the two clamping members descend to the sliding member, since the two clamping members are wedge-shaped, they can slide in a direction away from each other under the drive of the sliding member. When the two clamping members slide in a direction closer to each other, they can drive the sliding member to slide in a direction closer to the clamping seat.

[0023] As the slider moves closer to the locking seat, when it comes into contact with the locking seat, the conical surface of the slider and the curved surface of the locking seat connect. At this point, the two locking components can smoothly slide upwards from the slider and the locking seat, thus unlocking the locking components and the locking seat. After unlocking, the slider resets under its own weight.

[0024] Preferably, a guide rod is installed vertically between the clamping seat and the sliding member, and the sliding member is sleeved around the guide rod.

[0025] By adopting the above technical solution, the sliding of the slider is guided by the guide rod, thereby effectively ensuring the stability of the slider during the sliding process.

[0026] Preferably, a first latch and a second latch are provided between the inspection door and the silent housing. The first latch is used to lock the inspection door onto the silent housing, and the second latch is used to set the inspection door and the silent housing to a pre-open state. A rotating handle is installed on the outside of the inspection door, and both the first latch and the second latch are connected to the rotating handle.

[0027] By adopting the above technical solution, the ship's engine room environment is typically confined and involves frequent personnel movement. Traditional single-latch structures are easily opened accidentally due to unintentional bumps, leaning, or clothing snagging, leading to exposed high-temperature components of the operating generator set or noise leakage. Utilizing a two-lock structure—the first and second latches—creates a "foolproof" procedure. Workers must sequentially unlock both latches to open the access door. This dual-confirmation mechanism effectively eliminates the risk of accidental opening due to accidental contact.

[0028] Preferably, the first latch and the inner wall of the silent housing are kept locked together, the second latch is in an "L" shape, and a second movable groove is provided on the second latch to provide corresponding movement space for the inspection door.

[0029] By adopting the above technical solution, when the access door is closed, the first latch and the inner wall of the soundproof enclosure remain locked, and the access door is in the closed state. When the access door needs to be opened, the operator rotates the handle counterclockwise. In this state, the first latch is moved away, causing the second latch to move between the access door and the soundproof enclosure. At this time, the second movable groove on the second latch allows the access door to have a certain amount of movement space, placing it in a pre-opening state.

[0030] In this state, even if the first latch is unlocked, when the access door is opened outwards, the second latch will press against the limiting surface on the door frame, thus restricting the opening angle of the access door to a small range (e.g., 5-10 mm), forming only a "half-closed" gap, and preventing it from fully opening. Then, the handle must be rotated counterclockwise again to move the second latch, allowing the access door to be fully opened.

[0031] In summary, this application includes at least one of the following beneficial technical effects: 1. This design replaces the traditional method of securing the generator set with numerous bolts by employing a self-locking mechanism consisting of a locking rod and a locking seat. This snap-fit ​​connection allows for quick installation and removal of the silent housing from the base, significantly reducing the unit's assembly and disassembly time. When deep maintenance is required, the housing can be quickly and completely removed, eliminating the need for tedious screw tightening and thus significantly improving the generator set's maintenance efficiency.

[0032] This design also allows the entire soundproof enclosure to be completely removed, exposing critical components such as the engine, generator, and radiator. This completely breaks the limitations imposed on maintenance work by the narrow space inside traditional soundproof enclosures, allowing technicians to directly lift and replace parts on the unit without having to work in a confined space. This not only improves the convenience of operation but also enhances the safety and accuracy of the maintenance process. 2. When unlocking the silent housing and base, remove the cylinder and use a hoist to lift the silent housing. Lower the silent housing using the hoist; as it lowers, the locking rod will also lower, causing the locking components to descend. When the locking components reach the sliding components, the sliding components drive the two locking components to slide away from each other. In this state, the locking components compress the return spring.

[0033] As the clamping components continue to descend, the return spring releases its force, causing the two clamping components to slide closer to each other, and driving the sliding component to slide closer to the clamping seat. Subsequently, the hoisting machine begins to rise, causing the silent housing to rise as well. At this time, the sliding component unlocks the clamping components and the clamping seat as it slides closer to the clamping seat. 3. When the access door is closed, the first latch and the inner wall of the soundproof enclosure remain locked, and the access door is in the closed position. When the access door needs to be opened, the operator rotates the handle counterclockwise. In this state, the first latch is disengaged, causing the second latch to move between the access door and the soundproof enclosure. At this time, the second movable groove on the second latch allows the access door to have a certain amount of movement space, placing it in a pre-opening state.

[0034] In this state, even if the first latch is unlocked, when the access door is opened outwards, the second latch will press against the limiting surface on the door frame, thus restricting the opening angle of the access door to a small range (e.g., 5-10 mm), forming only a "half-closed" gap, and preventing it from fully opening. Then, the handle must be rotated counterclockwise again to move the second latch, allowing the access door to be fully opened. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0038] Example: This application discloses a small, easy-to-maintain marine silent generator set, referring to... Figure 1 and Figure 2The system includes a chassis, which consists of a silent outer shell 1 and a base 2, with the silent outer shell 1 covering the top of the base 2. The corresponding generator and engine are installed inside the silent outer shell 1. The interior of the silent outer shell 1 is filled with sound-absorbing cotton, and silencers are installed at the air inlet and outlet to reduce noise during operation. Additionally, a maintenance door 3 is located on the side of the silent outer shell 1, allowing technicians to quickly open the maintenance door 3 for maintenance of the components, generator, and engine inside the chassis.

[0039] A self-locking mechanism is installed between the silent housing 1 and the base 2, which enables quick installation and removal of the silent housing 1 and the base 2, thereby significantly improving the maintenance efficiency of the generator set. After the entire silent housing 1 of the generator set is removed, key components such as the engine, generator, and radiator can be completely exposed, allowing technicians to directly perform hoisting, parts replacement, and other operations without having to work in a confined space.

[0040] The self-locking mechanism is set in multiple groups, which are evenly distributed around the periphery of the silent shell 1 and the base 2. The multiple self-locking mechanisms effectively ensure the locking effect between the silent shell 1 and the base 2.

[0041] Specifically, refer to Figure 1 and Figure 2 The self-locking mechanism includes a locking rod 4 and a locking seat 5. The locking rod 4 is connected to the bottom of the silent housing 1, and the locking seat 5 is located on the top of the base 2. The locking rod 4 and the locking seat 5 are snapped together, and the locking rod 4 and the locking seat 5 are used to realize the quick installation and removal between the silent housing 1 and the base 2.

[0042] This design, using a self-locking mechanism consisting of a locking rod 4 and a locking seat 5, replaces the traditional method of securing the generator set with numerous bolts. This snap-fit ​​connection allows for quick installation and removal between the silent housing 1 and the base 2, significantly reducing the unit's assembly and disassembly time. When deep maintenance is required, the housing can be quickly removed as a whole, eliminating the need for tedious screw tightening and thus significantly improving the generator set's maintenance efficiency.

[0043] This design also allows the entire soundproof enclosure 1 to be completely removed, exposing critical components such as the engine, generator, and radiator. This completely breaks the limitations imposed by the narrow space inside traditional soundproof enclosures on maintenance work, allowing technicians to directly lift and replace parts on the unit without having to work in a confined space. This not only improves the convenience of operation but also enhances the safety and accuracy of the maintenance process.

[0044] Specifically, refer to Figure 2 and Figure 3The locking rod 4 has a slot 6 along its length, and two locking elements 7 are provided in the slot 6. The two locking elements 7 are distributed on the left and right sides of the slot 6, and the two locking elements 7 slide horizontally in a direction that moves closer or further apart from each other. The top of the locking seat 5 is integrally connected to a locking seat 8, and the locking seat 8 and the two locking elements 7 are engaged. The locking rod 4 and the locking seat 5 are engaged by the locking seat 8 and the two locking elements 7, thereby achieving the locking between the silent shell 1 and the base 2.

[0045] Specifically, the end of the clamping member 7 near the clamping seat 8 is wedge-shaped, and the clamping seat 8 is semi-circular in shape. The clamping seat 8 is used to drive the two clamping members 7 to slide in a direction away from each other.

[0046] During assembly, the silent housing 1 is hoisted using a hoisting machine, and the locking rod 4 at the bottom of the silent housing 1 is aligned with the corresponding locking seat 5. Then, the silent housing 1 is lowered. As the silent housing 1 continues to descend, the locking seat 8 enters the locking groove 6. At this time, the locking element 7 is located above the locking seat 8.

[0047] As the silent housing 1 continues to descend, when the clamping member 7 abuts against the top of the clamping seat 8, since the end of the clamping member 7 is wedge-shaped, in this state, as the silent housing 1 continues to descend, the clamping seat 8 drives the two clamping members 7 to slide away from each other. At this time, the silent housing 1 continues to descend, and when the two clamping members 7 descend to below the clamping seat 8, in this state, the two clamping members 7 slide towards each other.

[0048] At this time, the two clamping parts 7 are locked at the bottom of the clamping seat 8. The cylinder pushes the silent shell 1 upward. The locking seat 5 is fixed to the ground by fastening bolts. The cylinder pushes the silent shell 1 upward, so that the clamping parts 7 and the clamping seat 8 can always remain locked.

[0049] Specifically, refer to Figure 2 and Figure 3 A limiting groove 9 is formed in the locking rod 4 along the horizontal direction. The clamping member 7 is slidably installed in the limiting groove 9 along the horizontal direction. The limiting groove 9 provides corresponding space for the sliding of the clamping member 7. A return spring 10 is provided in the limiting groove 9. The return spring 10 is used to realize the sliding of the two clamping members 7 towards each other or away from each other.

[0050] When the two clamping parts 7 slide away from each other, the clamping parts 7 compress the return spring 10. When the two clamping parts 7 descend below the clamping seat 8, the return spring 10 releases its elastic force and drives the two clamping parts 7 to slide closer to each other.

[0051] Specifically, refer to Figure 2 and Figure 3The bottom of the clamping seat 8 is provided with a first movable groove 11, which is used to allow the two clamping parts 7 to slide towards the clamping seat 8.

[0052] When the two locking parts 7 descend to below the locking seat 8, the return spring 10 drives the two locking parts 7 to slide in the first movable groove 11 until the two locking parts 7 are locked below the locking seat 8.

[0053] Specifically, refer to Figure 2 and Figure 3 The bottom of the clamping seat 8 is provided with a slider 12. The slider 12 is used to drive the two clamping parts 7 to slide away from each other. The slider 12 slides towards or away from the clamping seat 8, and the process of the slider 12 sliding towards the clamping seat 8 completes the unlocking between the clamping parts 7 and the clamping seat 8.

[0054] Specifically, when unlocking the silent housing 1 and the base 2, the cylinder is removed, and the silent housing 1 is hoisted using a hoisting machine. The silent housing 1 is lowered using the hoisting machine, and simultaneously, the locking rod 4 is lowered, which in turn lowers the clamping member 7. When the clamping member 7 descends to the sliding member 12, the sliding member 12 drives the two clamping members 7 to slide away from each other. In this state, the clamping member 7 compresses the return spring 10.

[0055] As the clamping parts 7 continue to descend, the return spring 10 releases its elastic force, causing the two clamping parts 7 to slide towards each other, and driving the sliding part 12 to slide towards the clamping seat 8. Subsequently, the hoisting machine begins to rise, causing the silent housing 1 to rise as well. At this time, the sliding part 12 completes the unlocking between the clamping parts 7 and the clamping seat 8 as it slides towards the clamping seat 8.

[0056] Specifically, the slider 12 is cone-shaped as a whole.

[0057] The slider 12 is cone-shaped with a cone-shaped surface on its periphery. When the two clamping parts 7 descend to the slider 12, they are wedge-shaped and can slide away from each other under the drive of the slider 12. When the two clamping parts 7 slide towards each other, the slider 12 can be driven to slide towards the clamping seat 8.

[0058] As the slider 12 slides closer to the locking seat 8, when it comes into contact with the locking seat 8, the conical surface of the slider 12 and the curved surface of the locking seat 8 connect. At this point, the two locking parts 7 can smoothly slide upwards from the slider 12 and the locking seat 8, thus unlocking the locking parts 7 and the locking seat 8. After the locking parts 7 and the locking seat 8 are unlocked, the slider 12 resets under its own gravity.

[0059] Furthermore, referring to Figure 2 and Figure 3 A guide rod 13 is installed vertically between the clamping seat 8 and the sliding member 12. The sliding member 12 is sleeved around the guide rod 13. The guide rod 13 guides the sliding of the sliding member 12, thereby effectively ensuring the stability of the sliding member 12 during the sliding process.

[0060] Furthermore, referring to Figure 2 , Figure 3 as well as Figure 4 A first latch 14 and a second latch 15 are provided between the access door 3 and the silent housing 1. The first latch 14 is used to lock the access door 3 onto the silent housing 1, and the second latch 15 is used to set the access door 3 and the silent housing 1 to a pre-open state. A rotating handle 16 is installed on the outside of the access door 3, and both the first latch 14 and the second latch 15 are connected to the rotating handle 16.

[0061] Ship engine rooms are typically cramped and have high foot traffic. Traditional single-latch structures are easily opened accidentally by personnel bumping into them, leaning against them, or having their clothing snag on them, leading to exposed high-temperature components of the operating generator set or noise leakage. By utilizing a two-lock structure—first latch 14 and second latch 15—a "foolproof" procedure is created. Personnel must sequentially unlock both latches 14 and 15 to open the access door 3. This dual-confirmation mechanism effectively eliminates the risk of accidental opening due to unintentional contact.

[0062] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 The first latch 14 and the inner wall of the silent housing 1 are kept locked together. The second latch 15 is in the shape of an "L". The second latch 15 is provided with a second movable groove 17, which is used to provide corresponding movement space for the inspection door 3.

[0063] When the access door 3 is closed, the first latch 14 and the inner wall of the silent housing 1 remain locked, and the access door 3 is in the closed state. When the access door 3 needs to be opened, the operator rotates the handle 16 counterclockwise. In this state, the first latch 14 is moved away, causing the second latch 15 to move between the access door 3 and the silent housing 1. At this time, the second movable groove 17 on the second latch 15 allows the access door 3 to have a certain amount of room to move, and it is in a pre-opening state.

[0064] In this state, even if the first latch 14 is unlocked, when the access door 3 is opened outwards, the second latch 15 will press against the limiting surface on the door frame, thus limiting the opening angle of the access door 3 to a small range (e.g., 5-10 mm), forming only a "half-closed" gap, and it cannot be fully opened. Then, the handle 16 must be rotated counterclockwise again to move the second latch 15, so that the access door 3 can be fully opened.

[0065] Meanwhile, a sealing strip is installed on the inner side of the inspection door 3 along its perimeter. The sealing strip is integrally formed without any joints in the middle, so there will be no shrinkage or breakage problem, thus effectively ensuring the sealing effect between the inspection door 3 and the silent shell 1.

[0066] The implementation principle of an easy-to-maintain small marine silent generator set according to an embodiment of this application is as follows: A self-locking mechanism is installed between the silent housing 1 and the base 2, which enables quick installation and removal of the silent housing 1 and the base 2, thereby significantly improving the maintenance efficiency of the generator set. After the entire silent housing 1 of the generator set is removed, key components such as the engine, generator, and radiator can be completely exposed, allowing technicians to directly perform hoisting, parts replacement, and other operations without having to work in a confined space.

[0067] The self-locking mechanism is set in multiple groups, which are evenly distributed around the periphery of the silent shell 1 and the base 2. The multiple self-locking mechanisms effectively ensure the locking effect between the silent shell 1 and the base 2.

[0068] Specifically, the self-locking mechanism includes a locking rod 4 and a locking seat 5. The locking rod 4 is connected to the bottom of the silent housing 1, and the locking seat 5 is located on the top of the base 2. The locking rod 4 and the locking seat 5 are snapped together, and the locking rod 4 and the locking seat 5 are used to realize the quick installation and removal between the silent housing 1 and the base 2.

[0069] This design, using a self-locking mechanism consisting of a locking rod 4 and a locking seat 5, replaces the traditional method of securing the generator set with numerous bolts. This snap-fit ​​connection allows for quick installation and removal between the silent housing 1 and the base 2, significantly reducing the unit's assembly and disassembly time. When deep maintenance is required, the housing can be quickly removed as a whole, eliminating the need for tedious screw tightening and thus significantly improving the generator set's maintenance efficiency.

[0070] This design also allows the entire soundproof enclosure 1 to be completely removed, exposing critical components such as the engine, generator, and radiator. This completely breaks the limitations imposed by the narrow space inside traditional soundproof enclosures on maintenance work, allowing technicians to directly lift and replace parts on the unit without having to work in a confined space. This not only improves the convenience of operation but also enhances the safety and accuracy of the maintenance process.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
