Description

Technical Field

[0001] The present invention relates to the technical field of power generation equipment, and more specifically, to a high-efficiency power generation unit 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 for a long time, ships cannot do without power 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 belt generator system to generate electricity for the ship load. For example, the main shaft is driven by the ship power supply main engine to provide driving force for the shaft belt generator system, and then the shaft belt generator system converts the mechanical energy of the propulsion shaft into electrical energy to power the ship load. However, the main power supply system is greatly affected by the power factor of the ship's main shaft. Once the ship's power supply main engine 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 their high thermal efficiency, reliable operation, and long life.

[0003] The International Maritime Organization stipulates that ships should be equipped with backup generators when sailing long distances in case of emergency. The International Maritime Organization has formulated corresponding regulations based on different types of ships. For example, some large tankers and cargo ships require three or more backup generators to meet their energy needs. However, the installation of three or more backup generators requires more ship space, has low space utilization, low power generation efficiency, and significantly increases the purchase cost, maintenance complexity and maintenance cost, reducing the economic efficiency of ship transportation.

[0034] according to Figure 1-Figure 9 As shown, a high-efficiency generator set for an offshore platform includes a first standby generator assembly, a second standby generator assembly and a transmission switching member, wherein the first standby generator assembly is arranged on a ship through a shock absorbing platform, the transmission switching member is arranged on the first standby generator assembly, and the second standby generator assembly is arranged on the shock absorbing platform. The shock absorbing platform provides shock absorbing effect for the first standby generator assembly and the second standby generator assembly. Furthermore, the shock absorbing platform adopts existing shock absorbing technology, which will not be described in detail 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 member includes a first friction active transmission member, a first meshing active transmission member and a first axial stabilizing member, and the first friction active transmission member, the first meshing active transmission member and the first axial stabilizing member are all arranged on the first diesel engine 1 .

[0037] The first friction active transmission member includes 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, and the first slider on the inner wall of the first friction active transmission tube 3 cooperates with the first slide groove on the output shaft 35 of the first diesel engine 1, so that the first friction active transmission tube 3 is circumferentially transmitted and axially slid on the output shaft 35 of the first diesel engine 1 through the first slider and the first slide groove. The first magnetic coil is fixedly embedded in the first spiral groove on the inner wall of the first friction active transmission tube 3. When a direct current is input into the first magnetic coil to generate a magnetic field, the first friction active transmission tube 3 is pushed to slide axially on the output shaft 35 of the first diesel engine 1. The first friction disc 4 is in the shape of a truncated cone, and the first friction disc 4 is fixedly mounted on one end of the first friction active transmission tube 3 and moves with it. Then, the first friction disc 4 is driven by the first friction active transmission tube 3 to slide axially, and frictionally transmits circumferentially with the transmission switching member, so as to facilitate the first meshing active transmission member to mesh with the transmission switching member for transmission.

[0038] The first meshing active transmission member includes a first meshing active transmission tube 5, a second magnetic coil, a first meshing active transmission groove 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 the second slider on the inner wall of the first meshing active transmission tube 5 cooperates with the first slide groove, so that the first meshing active transmission tube 5 is circumferentially transmitted and axially slid on the output shaft 35 of the first diesel engine 1 through the second slider and the first slide groove. Further, one end of the first meshing active transmission tube 5 is slidably embedded in the first bearing on one end of the switching transmission housing 8, so that the first meshing active transmission tube 5 axially seals and slides in the inner ring of the first bearing. The switching transmission housing 8 is arranged 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 arc surface height of the other end of the first stabilizing shaft 10. So that the first meshing active transmission tube 5 can be axially stabilized 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 in the axial direction with a force greater than the axial resistance of the first stable shaft 10 to the first meshing active transmission tube 5 through the first stable groove, the first meshing active transmission tube 5 will compress the first stable shaft 10 through the first stable groove and retract it into the first stable hole, thereby achieving the axial sliding of the first meshing active transmission tube 5. When the first end gear plate 7 is fully meshed with the transmission switching member, the other end of the first stable shaft 10 is aligned with the second stable groove on the inner wall of the first meshing active transmission tube 5 and is pushed in by the first return spring. This allows the first end gear plate 7 to stably mesh with the transmission switching member, preventing the first end gear plate 7 from disengaging from the transmission switching member and unstable meshing transmission when the ship is bumping on the sea or when the first diesel engine 1 reduces or increases its speed.

[0042] The first generator 2 is fixedly arranged on the vibration-absorbing 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 arranged on the first generator 2, and the first meshing driven transmission member and the second axial stabilizing member are both arranged on the first friction driven transmission member.

[0043] The first friction driven transmission member includes a driven tube 11, a first friction driven transmission tube 12, a third magnetic coil and a second friction disk 13. One end of the driven tube 11 is fixedly sleeved on the free end of the input shaft of the first generator 2, and the other end of the driven tube 11 is circumferentially sleeved on the free end of the output shaft 35 of the first diesel engine 1. The first friction driven transmission tube 12 is slidably sleeved on the other end of the driven tube 11, and the third slider on the inner wall of the first friction driven transmission tube 12 cooperates with the second slide groove on the outer wall of the driven tube 11, so that the first friction driven transmission tube 12 is circumferentially transmitted and axially slid on the driven tube 11 through the third slider and the second slide groove. The third magnetic coil is fixedly embedded in the third spiral groove on the inner wall of the first friction driven transmission tube 12. When direct current is input into the third magnetic coil to generate a magnetic field, the first friction driven transmission tube 12 will be pushed to slide axially on the driven tube 11. The second friction disc 13 is in the shape of a truncated cone, and is fixedly mounted on one end of the first friction driven transmission tube 12. The second friction disc 13 is driven by the first friction driven transmission tube 12 to slide axially, so that the second friction disc 13 and the transmission switching member are frictionally transmitted in a circumferential direction, thereby preventing the first meshing driven transmission member from hitting the teeth during the meshing process with the transmission switching member.

[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 the fourth slider on the inner wall of the first meshing driven transmission tube 14 cooperates with the second slide groove on the driven tube 11, so that the first meshing driven transmission tube 14 is circumferentially transmitted and axially slid on the driven tube 11 through the fourth slider and the second slide groove. Further, one end of the first meshing driven transmission tube 14 is slidably embedded in the second bearing on the other end of the switching transmission housing 8, so that the first meshing driven transmission tube 14 is axially sealed and slid 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, the first meshing driven transmission tube 14 will be pushed to slide axially on the driven tube 11. The first meshing driven transmission groove 15 is in the shape of a circular groove, 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, and 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 sleeved 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 toothed 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 toothed 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 is set on the side wall of the driven tube 11 through the inside of the driven tube 11, and the other end of the radial tube is closed. 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, and 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 surface. The other end of the second stabilizing shaft 19 is pushed by the second return spring to fit into the 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 groove, and the groove depth of the third stabilizing groove is less than the arc surface height of the other end of the second stabilizing shaft 19. So that the first meshing driven transmission tube 14 can be axially stabilized 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 stable shaft 19 to the first meshing driven transmission tube 14 through the third stable groove, the first meshing driven transmission tube 14 will compress the second stable shaft 19 through the third stable groove to retract into the radial tube, thereby achieving the axial sliding of the first meshing driven transmission tube 14. When the second end gear plate 16 is fully meshed with the transmission switching member, the other end of the second stable shaft 19 is aligned with the fourth stable groove on the inner wall of the first meshing driven transmission tube 14 and pushed in by the second return spring, so that the second end gear plate 16 is stably meshed with the transmission switching member, so as to prevent the second end gear plate 16 from being disengaged from the transmission switching member and the meshing transmission from being unstable when the ship is bumping at sea or when the first diesel engine 1 is reducing or increasing its speed.
