Description

Technical Field

[0001] The present invention relates to the technical field of power generation equipment, and more particularly to a high-efficiency generator set for an offshore platform. Background Art

[0002] Ships are the main means of transportation for economic trade in various countries. In order to be able to perform transportation tasks reliably and long-term, ships cannot do without electricity supply. The existing power supply systems on ships are divided into main power supply systems and backup power supply systems. The main power supply system mainly relies on the shaft generator system to generate electricity for the ship's load. For example, the main shaft is driven by the ship's main power supply unit to provide driving force for the shaft generator system, and then the shaft generator system converts the mechanical energy of the propulsion shaft into electrical energy to power the ship's load. However, the main power supply system is greatly affected by the power factors of the ship's main shaft. Once the ship's main power supply unit fails, it will directly affect the safety of the ship's navigation at sea. The backup power supply system mainly relies on backup diesel generators to generate electricity. Diesel generator sets have become the preferred backup power source for ship backup power supply systems due to a series of advantages such as high thermal efficiency, reliable operation, and long life.

[0003] The International Maritime Organization (IMO) stipulates that ships undertaking long-distance voyages must be equipped with backup generator sets in case of emergency. The IMO has formulated specific regulations based on the type of vessel. For example, some large oil tankers and cargo ships require three or more backup generator sets to meet their energy needs. However, installing three or more backup generator sets requires more space on board, resulting in low space utilization and power generation efficiency. This significantly increases purchase costs, complexity, and maintenance costs, reducing the economic efficiency of shipping. Summary of the Invention

DETAILED DESCRIPTION

[0032] The technical solutions of the present invention will be described in detail below by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist at the same time. The term " / and" in this article describes another type of association object relationship, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0034] according to Figures 1-9 As shown, a high-efficiency generator set for an offshore platform includes a first backup generator assembly, a second backup generator assembly, and a transmission switching element. The first backup generator assembly is mounted on a vessel via a shock-absorbing platform, the transmission switching element is mounted on the first backup generator assembly, and the second backup generator assembly is mounted on the shock-absorbing platform. The shock-absorbing platform provides shock absorption for the first and second backup generator assemblies. Furthermore, the shock-absorbing platform utilizes existing shock absorption technology, which will not be further described here.

[0035] The first standby generator assembly includes a first diesel engine 1, a first active transmission member, a first generator 2 and a first driven transmission member. The first diesel engine 1 is arranged on the shock-absorbing platform to output power. The first active transmission member is arranged on the first diesel engine 1. The first generator 2 is arranged on the shock-absorbing platform. The first driven transmission member is arranged on the first generator 2, and the first driven transmission member is connected to the first active transmission member for transmission through the transmission switching member.

[0036] The first active transmission component includes a first friction active transmission component, a first meshing active transmission component and a first axial stabilizing component. The first friction active transmission component, the first meshing active transmission component and the first axial stabilizing component are all arranged on the first diesel engine 1.

[0037] The first friction active transmission element comprises a first friction active transmission tube 3, a first magnetic coil, and a first friction disc 4. The first friction active transmission tube 3 is slidably mounted on the free end of the output shaft 35 of the first diesel engine 1. A first slider on the inner wall of the first friction active transmission tube 3 engages with a first groove on the output shaft 35 of the first diesel engine 1, enabling the first friction active transmission tube 3 to transmit circumferentially and slide axially on the output shaft 35 of the first diesel engine 1 via the first slider and the first groove. The first magnetic coil is fixedly mounted within a first spiral groove on the inner wall of the first friction active transmission tube 3. When DC current is input into the first magnetic coil to generate a magnetic field, it forces the first friction active transmission tube 3 to slide axially on the output shaft 35 of the first diesel engine 1. The first friction disc 4 is shaped like a truncated cone and is fixedly mounted on one end of the first friction active transmission tube 3 for follower movement. Driven by the first friction active transmission tube 3, the first friction disc 4 slides axially, frictionally transmitting circumferentially with the transmission switching element, thereby facilitating meshing and transmission between the first meshing active transmission element and the transmission switching element.

[0038] The first meshing active transmission member includes a first meshing active transmission tube 5, a second magnetic coil, a first meshing active transmission slot 6, and a first end gear plate 7. The first meshing active transmission tube 5 is slidably mounted on the free end of the output shaft 35 of the first diesel engine 1, and a second slider on the inner wall of the first meshing active transmission tube 5 cooperates with the first slot, allowing the first meshing active transmission tube 5 to transmit circumferentially and slide axially on the output shaft 35 of the first diesel engine 1 via the second slider and the first slot. Furthermore, one end of the first meshing active transmission tube 5 is slidably mounted within a first bearing on one end of a switching transmission housing 8, allowing the first meshing active transmission tube 5 to slide axially and sealed within the inner ring of the first bearing. The switching transmission housing 8 is disposed on the damping platform.

[0039] The second magnetic coil is fixedly embedded in the second spiral groove on the inner wall of the first meshing active transmission tube 5. When direct current is input into the second magnetic coil to generate a magnetic field, the first meshing active transmission tube 5 will be pushed to slide axially on the output shaft 35 of the first diesel engine 1. The first meshing active transmission groove 6 is in the shape of a circular groove, and the groove depth of the first meshing active transmission groove 6 is greater than the length of the first friction active transmission tube 3, and the inner diameter of the first meshing active transmission groove 6 is greater than the bottom diameter of the first friction disk 4. The bottom of the first meshing active transmission groove 6 is fixedly sleeved on one end of the first meshing active transmission tube 5 and moves with it, and the axis of the first meshing active transmission groove 6 coincides with the axis of the first meshing active transmission tube 5. The first end toothed disc 7 is fixedly set on the notch of the first meshing active transmission groove 6 and moves with it, and the axis of the first end toothed disc 7 coincides with the axis of the first meshing active transmission groove 6.

[0040] The first axial stabilizing member includes a first return spring and a first stabilizing shaft 10. The first return spring is embedded in the first stabilizing hole on the output shaft 35 of the first diesel engine 1. The axis of the first stabilizing hole is parallel to the radial line of the output shaft 35 of the first diesel engine 1. One end of the first stabilizing shaft 10 is slidably embedded in the first stabilizing hole, and one end of the first stabilizing shaft 10 is connected to the free end of the first return spring. The other end of the first stabilizing shaft 10 is in the shape of an arc surface. The other end of the first stabilizing shaft 10 is pushed by the first return spring to fit into the first stabilizing groove on the inner wall of the first meshing active transmission tube 5. The first stabilizing groove is in the shape of an arc groove, and the groove depth of the first stabilizing groove is less than the height of the arc surface at the other end of the first stabilizing shaft 10. This facilitates the axial stability of the first meshing active transmission tube 5 on the output shaft 35 of the first diesel engine 1.

[0041] When the magnetic field generated by the first magnetic coil drives the first meshing active transmission tube 5 to slide axially with a force greater than the axial resistance of the first stabilizing shaft 10 to the first meshing active transmission tube 5 through the first stabilizing groove, the first meshing active transmission tube 5 will compress the first stabilizing shaft 10 through the first stabilizing groove and retract it into the first stabilizing hole, thereby achieving axial sliding of the first meshing active transmission tube 5. When the first end gear disc 7 is fully engaged with the transmission switching member, the other end of the first stabilizing shaft 10 is aligned with the second stabilizing groove on the inner wall of the first meshing active transmission tube 5 and is pushed in by the first return spring. This ensures that the first end gear disc 7 is stably engaged with the transmission switching member, preventing the first end gear disc 7 from disengaging from the transmission switching member and preventing the meshing transmission from becoming unstable when the ship is bumping on the sea or when the first diesel engine 1 is reducing or increasing its speed.

[0042] The first generator 2 is fixedly mounted on the vibration-damping platform to be driven to generate electricity. The first driven transmission member includes a first friction driven transmission member, a first meshing driven transmission member, and a second axial stabilizing member. The first friction driven transmission member is mounted on the first generator 2, and the first meshing driven transmission member and the second axial stabilizing member are both mounted on the first friction driven transmission member.

[0043] The first friction driven transmission element comprises a driven tube 11, a first friction driven transmission tube 12, a third magnetic coil, and a second friction disc 13. One end of the driven tube 11 is fixedly mounted on the free end of the input shaft of the first generator 2, and the other end of the driven tube 11 is rotatably mounted on the free end of the output shaft 35 of the first diesel engine 1. The first friction driven transmission tube 12 is slidably mounted on the other end of the driven tube 11. A third slider on the inner wall of the first friction driven transmission tube 12 engages with a second groove on the outer wall of the driven tube 11, enabling the first friction driven transmission tube 12 to circumferentially transmit power and slide axially on the driven tube 11 via the third slider and second groove. The third magnetic coil is fixedly mounted within a third spiral groove on the inner wall of the first friction driven transmission tube 12. When DC current is input into the third magnetic coil to generate a magnetic field, it forces the first friction driven transmission tube 12 to slide axially on the driven tube 11. The second friction disc 13 is shaped like a truncated cone and is fixedly mounted on one end of the first friction driven transmission tube 12. The second friction disc 13 is then driven by the first friction driven transmission tube 12 to slide axially, causing friction between the second friction disc 13 and the transmission switching element to generate circumferential transmission, thereby preventing tooth chattering during engagement between the first meshing driven transmission element and the transmission switching element.

[0044] The first meshing driven transmission member includes a first meshing driven transmission tube 14, a fourth magnetic coil, a first meshing driven transmission groove 15, and a second end gear plate 16. The first meshing driven transmission tube 14 is slidably mounted on the other end of the driven tube 11, and a fourth slider on the inner wall of the first meshing driven transmission tube 14 cooperates with a second slide groove on the driven tube 11, so that the first meshing driven transmission tube 14 is circumferentially driven and slides axially on the driven tube 11 via the fourth slider and the second slide groove. Furthermore, one end of the first meshing driven transmission tube 14 is slidably mounted in a second bearing on the other end of the switching transmission housing 8, so that the first meshing driven transmission tube 14 slides axially and sealed in the inner ring of the second bearing.

[0045] The fourth magnetic coil is fixedly embedded in the fourth spiral groove on the inner wall of the first meshing driven transmission tube 14. When direct current is input into the fourth magnetic coil to generate a magnetic field, it will push the first meshing driven transmission tube 14 to slide axially on the driven tube 11. The first meshing driven transmission groove 15 is circular, and the groove depth of the first meshing driven transmission groove 15 is greater than the length of the first friction driven transmission tube 12. The inner diameter of the first meshing driven transmission groove 15 is greater than the bottom diameter of the second friction disk 13. The bottom surface of the first meshing driven transmission groove 15 is fixedly mounted on one end of the first meshing driven transmission tube 14 and moves with it, and the axis of the first meshing driven transmission groove 15 coincides with the axis of the first meshing driven transmission tube 14. The second end gear disc 16 is fixedly set on the notch of the first meshing driven transmission groove 15 and moves with it, and the axis of the second end gear disc 16 coincides with the axis of the first meshing driven transmission groove 15.

[0046] The second axial stabilizing member includes a radial tube, a second return spring, and a second stabilizing shaft 19. One end of the radial tube extends through the driven tube 11 and is disposed on the sidewall of the driven tube 11. The other end of the radial tube is closed, and the axis of the radial tube coincides with the radial line of the driven tube 11. The second return spring is embedded in the radial tube, and one end of the second stabilizing shaft 19 is slidably embedded in the other end of the radial tube. One end of the second stabilizing shaft 19 is connected to the free end of the second return spring. The other end of the second stabilizing shaft 19 is in the shape of an arc. The other end of the second stabilizing shaft 19 is pushed by the second return spring to fit into a third stabilizing groove on the inner wall of the first meshing driven transmission tube 14. The third stabilizing groove is in the shape of an arc, and its depth is less than the height of the arc surface at the other end of the second stabilizing shaft 19. This facilitates axial stabilization of the first meshing driven transmission tube 14 on the driven tube 11.

[0047] When the magnetic field generated by the third magnetic coil drives the first meshing driven transmission tube 14 to slide axially with a force greater than the axial resistance of the second stabilizing shaft 19 to the first meshing driven transmission tube 14 through the third stabilizing groove, the first meshing driven transmission tube 14 will compress the second stabilizing shaft 19 through the third stabilizing groove and retract it into the radial tube, thereby achieving axial sliding of the first meshing driven transmission tube 14. When the second end gear disc 16 is fully engaged with the transmission switching member, the other end of the second stabilizing shaft 19 is aligned with the fourth stabilizing groove on the inner wall of the first meshing driven transmission tube 14 and is pushed in by the second return spring, so that the second end gear disc 16 is stably engaged with the transmission switching member, thereby preventing the second end gear disc 16 from disengaging from the transmission switching member and preventing the meshing transmission from becoming unstable when the ship is bumping at sea or when the first diesel engine 1 is reducing or increasing its speed.

[0048] The second backup generator assembly includes a second diesel engine 20, a second active transmission member, a second generator 21, and a second driven transmission member.
