A marine diesel generator set with a fire pump

Abstract

This utility model discloses a marine diesel generator set with a fire pump, within the technical field of marine generator sets. It includes a diesel engine, with the output end of the diesel engine connected to the generator. The key feature is that the diesel engine is positioned in the middle of an extended base, the generator is positioned at the front of the extended base, and the free end of the diesel engine is connected to the fire pump via a switching connection mechanism. This switching connection mechanism and the fire pump are located at the rear of the extended base. By connecting the fire pump to the free end of the diesel engine while the output end of the diesel engine remains connected to the generator, under normal operating conditions, the diesel engine only drives the generator to provide power to the ship. If another vessel catches fire, the fire pump can be started via the switching connection mechanism to facilitate rescue operations while simultaneously continuing to supply power. This not only reduces the space occupied by marine equipment but also effectively lowers the cost of marine equipment without affecting the ship's normal power supply.

Description

Technical Field

[0001] This utility model relates to a marine diesel generator set with a fire pump in the field of marine generator set technology. Background Technology

[0002] When ships are navigating on water, ensuring fire safety and facilitating mutual rescue among vessels is crucial. Therefore, fire pumps are essential, allowing nearby ships to respond to a fire on one vessel. In current technology, the fire pump is connected to the output of a diesel engine, while the ship also has a generator set installed for power supply, connected to the diesel engine's output. This reliance on independent diesel engines for both firefighting and power generation not only occupies more cabin space but also indirectly increases the cost of marine equipment. Utility Model Content

[0003] The purpose of this invention is to provide a marine diesel generator set with a fire pump, which can not only reduce the space occupied by marine equipment, but also effectively reduce the cost of marine equipment, and will not affect the normal power supply of the ship.

[0004] To achieve the above objectives, this utility model provides a marine diesel generator set with a fire pump, including a diesel engine, the output end of which is connected to the generator. The diesel engine is located in the middle of the extended base, the generator is located in the front of the extended base, the free end of the diesel engine is connected to the fire pump via a switching connection mechanism, and the switching connection mechanism and the fire pump are located in the rear of the extended base.

[0005] Compared with the prior art, the beneficial effects of this utility model are that by connecting the fire pump to the free end of the diesel engine, while the output end of the diesel engine remains connected to the generator, the diesel engine only drives the generator to work during normal operation, providing normal power to the ship. However, if another ship is on fire, the fire pump can be started by switching the connection mechanism to achieve rescue, and at the same time, it can continue to supply power to the outside. This not only reduces the space occupied by marine equipment, but also effectively reduces the cost of marine equipment, and does not affect the normal power supply of the ship.

[0006] As a further improvement of this utility model, the switching connection mechanism includes a shock absorber connected to the free end of the diesel engine, the shock absorber being connected to a high-elasticity coupling, the high-elasticity coupling being connected to a clutch, and the clutch being connected to a fire pump.

[0007] This damper reduces the vibration output from the free end of the diesel engine, while the highly flexible coupling compensates for misalignment caused by the transmission connection, ensuring the synchronization of the transmission and ultimately connecting the diesel engine and the clutch.

[0008] As a further improvement of this utility model, the extended base includes a pair of long frames, a pair of front longitudinal beams are provided between the front parts of the long frames, with a gap between the front longitudinal beams, and the generator is installed on the front longitudinal beams. A pair of middle longitudinal beams are provided between the middle parts of the long frames, with a gap between the middle longitudinal beams, and the diesel engine is installed on the middle longitudinal beams. A pair of rear longitudinal beams are provided between the rear parts of the long frames, with a gap between the rear longitudinal beams, and the clutch and the fire pump are respectively installed on the pair of rear longitudinal beams.

[0009] This extended base, consisting of long side frames and longitudinal beams, allows fire pumps, clutches, diesel engines, and generators to be installed and secured as a whole inside the ship's cabin.

[0010] As a further improvement of this utility model, a pair of reinforcing ribs are connected between the rear longitudinal beam where the clutch is located and the adjacent middle longitudinal beam.

[0011] This can improve the structural strength of the middle and rear of the extended base.

[0012] As a further improvement of this utility model, a protective cover is provided on the outer periphery of the shock absorber and the high-elasticity coupling, and the bottom of the protective cover is installed on the reinforcing rib.

[0013] This protects the shock absorber and the high-elasticity coupling by using a protective cover, preventing the fire pump from failing to start due to impacts or other reasons.

[0014] As a further improvement of this utility model, multiple vibration isolators are installed at the bottom of the long frame.

[0015] This can reduce and eliminate the vibration force transmitted from the equipment to the foundation and the vibration transmitted from the foundation to the equipment, further improving the overall stability of the equipment operation. Attached Figure Description

[0018] Figure 3 This is a structural schematic diagram of the extended base of this utility model.

[0019] Among them, 1 is a fire pump, 2 is a clutch, 3 is a protective cover, 4 is a diesel engine, 5 is a generator, 6 is a long frame, 7 is a shock absorber, 8 is a high-elasticity coupling, 9 is a vibration isolator, 10 is a rear longitudinal beam, 11 is a middle longitudinal beam, 12 is a front longitudinal beam, and 13 is a reinforcing rib. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-3The marine diesel generator set with a fire pump shown includes a diesel engine 4, the output end of which is connected to a generator 5. The diesel engine 4 is located in the middle of an extended base, the generator 5 is located in the front of the extended base, the free end of the diesel engine 4 is connected to a fire pump 1 via a switching connection mechanism, and the switching connection mechanism and the fire pump 1 are located at the rear of the extended base.

[0021] The switching connection mechanism includes a shock absorber 7 connected to the free end of the diesel engine 4, which is connected to a high-elasticity coupling 8. The high-elasticity coupling 8 is connected to a clutch 2, which is connected to the fire pump 1.

[0022] The extended base includes a pair of long frame frames 6, a pair of front longitudinal beams 12 are provided between the front parts of the long frame frames 6, with a gap between the front longitudinal beams 12, the generator 5 is mounted on the front longitudinal beams 12, a pair of middle longitudinal beams 11 are provided between the middle parts of the long frame frames 6, with a gap between the middle longitudinal beams 11, the diesel engine 4 is mounted on the middle longitudinal beams 11, a pair of rear longitudinal beams 10 are provided between the rear parts of the long frame frames 6, with a gap between the rear longitudinal beams 10, the clutch 2 and the fire pump 1 are respectively mounted on the pair of rear longitudinal beams 10.

[0023] A pair of reinforcing ribs 13 connect the rear longitudinal beam 10, where the clutch 2 is located, to the adjacent middle longitudinal beam 11. A protective cover 3 is provided around the outer periphery of the shock absorber 7 and the high-elasticity coupling 8, with the bottom of the protective cover 3 mounted on the reinforcing ribs 13. Multiple vibration isolators 9 are installed at the bottom of the long frame 6.

[0024] In this utility model, an extended base is formed by a long frame 6 and longitudinal beams. The fire pump 1 is installed on the rear longitudinal beam 10 closest to the rear end of the base, the clutch 2 is installed on another rear longitudinal beam 10, the diesel engine 4 is straddling a pair of middle longitudinal beams 11, and the generator 5 is straddling a pair of front longitudinal beams 12. The long frame 6 base is fixedly connected to the foundation of the ship's cabin through vibration isolators 9. This design can ensure the overall structural strength of the equipment installation, effectively reduce the weight of the base, and save costs.

[0025] The free end of the diesel engine 4 is connected to the clutch 2 via the shock absorber 7 and the high-elasticity coupling 8. The clutch 2 is connected to the fire pump 1, and the output end of the diesel engine 4 is still connected to the generator 5. The shock absorber 7 can reduce the vibration output of the free end of the diesel engine 4, while the high-elasticity coupling 8 can compensate for the misalignment caused by the transmission connection, ensure the synchronization of the transmission, and finally connect the diesel engine 4 and the clutch 2.

[0026] When operating normally, clutch 2 is in neutral, allowing diesel engine 4 to drive generator 5 to provide power to the ship. However, if another vessel catches fire, the speed of diesel engine 4 needs to be reduced to a low speed, and then clutch 2 is shifted to allow diesel engine 4 to drive fire pump 1, continuously outputting high-pressure water jets to help extinguish the fire. At the same time, the power output of diesel engine 4 to generator 5 is the rated power minus the output power of fire pump 1, still enough to continue supplying power. Furthermore, multiple generator sets 5 are equipped on board. Generally, only the free ends of two diesel engines 4 need to be connected to fire pump 1, while the output ends of the remaining diesel engines 4 are only connected to generator 5. Therefore, when the ship stops and fire pump 1 is started to extinguish the fire, the output power of all generator sets 5 can still guarantee the power supply to the entire ship.

[0027] This invention not only reduces the space occupied by marine equipment, but also effectively reduces the cost of marine equipment, and does not affect the normal power supply of the ship.

[0028] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
