Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator sets, and in particular to a high-efficiency diesel generator set. Background Art

[0002] A diesel generator consists of a diesel engine and a generator. It generates high temperature and pressure by compressing air, injecting diesel into the cylinder and igniting it. The combustion energy pushes the pistons to produce work, driving the crankshaft. The generator, in turn, uses the crankshaft's mechanical energy to rotate the rotor, converting this energy into electrical energy through electromagnetic induction, thus outputting alternating current. These generators offer high efficiency, strong reliability, rapid startup, and wide adaptability, making them widely used in backup power supplies, emergency power supplies, construction sites, and remote areas.

[0003] Existing technologies often connect the diesel engine's crankshaft to the generator's rotor through a coupling. If the generator's rotor suddenly gets stuck due to poor lubrication (for various reasons, such as use in extremely cold regions causing the lubricating oil to become viscous, resulting in increased resistance to rotor rotation), when the resistance to rotation of the generator rotor increases, according to Newton's third law (action and reaction), the generator will generate a reaction torque on the diesel engine that drives it. The direction of this reaction torque is opposite to the driving torque output by the engine. This increased reaction torque will be directly and completely transmitted back to the diesel engine's crankshaft, causing the diesel engine to not only overcome the load torque required for normal power generation by the generator at room temperature, but also to overcome the additional resistance torque caused by the high-viscosity engine oil, thereby significantly increasing the actual output load of the diesel engine and causing increased stress on internal components when the diesel engine is started, thereby increasing the risk of damage. In severe cases (jamming), it may even cause irreversible damage to the crankshaft or rotor. Summary of the Invention

DETAILED DESCRIPTION

[0018] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0019] Example 1

[0020] This embodiment discloses a high-efficiency diesel generator set, which is used to disable the power connection between the crankshaft and the rotor when the generator load is too large or the crankshaft, rotor, etc. are suddenly stuck, so as to prevent further damage.

[0021] like Figure 1-Figure 5As shown, the diesel generator set includes a frame 1, which is a high-strength steel structure. A diesel engine 2 and a generator 3 are fixed to the frame 1. The turbine installed on the diesel engine 2 is a variable cross-sectional area turbine, which can adjust the angle of its internal guide vanes according to the exhaust volume, thereby ensuring its stable rotation, maintaining stable intake pressure, ensuring efficient operation of the diesel engine 2, and reducing the probability of incomplete combustion of fuel, thereby achieving the purpose of energy conservation and emission reduction. The rotor of the generator 3 is fixed to a power shell 4, which is sealed and rotatably connected to a transfer shell 5. The power shell 4 and the transfer shell 5 are connected in a sealed manner. There are through holes on both sides. In case of emergency, the power shell 4 and the transfer shell 5 can be rigidly connected by bolts to maintain power transmission. The power shell 4 and the transfer shell 5 are filled with a fluid for transmission (the fluid has antifreeze properties). The transfer shell 5 is fixed with a receiving shell 6. The crankshaft of the diesel engine 2 is fixed with the receiving shell 6. The receiving shell 6 is also a high-strength steel structure to ensure its stable transmission during high-intensity rotation. The power shell 4 is provided with a chimeric unit for ensuring transmission safety; the chimeric unit includes four first chimeric members 7 distributed in a circumferential array, four second chimeric members 7, and four third chimeric members 7. Each of the first and second interlocking parts 7 is fixed to the power shell 4. The intermediate shell 5 is slidably connected to four second interlocking parts 8 distributed in a circumferential array. A limit ring is provided on the second interlocking part 8 to limit the sliding range of the second interlocking part 8 to ensure stable contact between the first interlocking part 7 and the second interlocking part 8. The first interlocking part 7 and the second interlocking part 8 are both provided with two inclined surfaces distributed in a mirror image, and the two adjacent ones are interlocked with each other (V-shaped interlocking). The angle between the two inclined surfaces on the first interlocking part 7 is an obtuse angle. The four second interlocking parts 8 are commonly fixed to a fixing frame 9. The fixing frame 9 Located in the receiving shell 6, a sliding frame 10 is slidably connected to the fixed frame 9, and a fastening spring 11 is fixed between the sliding frame 10 and the transfer shell 5. The fastening spring 11 is a tension spring and is used to provide a fastening force between the first fitting 7 and the second fitting 8. An adjusting rod 12 rotatably connected to the sliding frame 10 is threadedly connected to the fixed frame 9. Before use, the degree of stretching of the fastening spring 11 (i.e., the tension provided by the fastening spring 11) can be adjusted according to the power, load and other parameters of the diesel engine and generator. A high-speed limit mechanism for protecting the drive shaft is provided on the fixed frame 9.

[0022] like Figure 4-Figure 6As shown, the high-speed limiting mechanism includes four centrifugal blocks 13 distributed in a circumferential array. The centrifugal block 13 consists of a rectangular block and a round rod, and the round rod part is provided with two inclined surfaces distributed in a mirror image. The four centrifugal blocks 13 are all slidably connected to the fixed frame 9. A spring is provided between the centrifugal block 13 and the fixed frame 9. When the diesel generator is started, the four centrifugal blocks 13 rotate together, and the centrifugal blocks 13 move to the side away from the axis of the transfer shell 5 under the action of centrifugal force during rotation, while squeezing the adjacent springs. Four fixed plates 14 distributed in a circumferential array are fixed to the receiving shell 6. Two limiting members 15 distributed in a mirror image are slidably connected to the fixed plate 14. The centrifugal block 13 is used to squeeze the corresponding two limiting members 15. The opposite sides of the two limiting members 15 on the same fixed plate 14 are provided with inclined surfaces. The limiting member 15 is provided with a through hole for limiting the position of the centrifugal block 13. The inclination angle of the inclined surface on the limiting member 15 is the same as the inclination angle of the inclined surface adjacent to the round rod part of the adjacent centrifugal block 13. A tension spring is provided between the two limiting members 15.

[0023] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: Preparation stage: (hereinafter referred to as Figure 4 (Taking the orientation as an example), first lay the power housing 4 horizontally and inject transmission fluid into the power housing 4. Then, seal and rotate the power housing 4 and the transfer housing 5 together. After the two are sealed, install the receiving housing 6 and the transfer housing 5 and the parts thereon on the crankshaft of the diesel engine 2 with bolts. Then, adjust the tightening force between the first insert 7 and the second insert 8 according to the power load of the diesel engine 2 and the generator 4. Turn the adjusting rod 12, and the adjusting rod 12 drives the sliding frame 10 to the right, thereby increasing the tension of the tightening spring 11 (that is, increasing the tightening force between the first insert 7 and the second insert 8). After the adjustment is completed, connect the receiving housing 6 to the right side of the transfer housing 5 with bolts. Then, connect the rotor of the generator 3 to the right side of the receiving housing 6 with bolts. At this time, preparation is complete.

[0024] Working stage: After the preparation work is completed, the diesel engine 2 is started, and the crankshaft of the diesel engine 2 drives the receiving shell 6 to rotate, and the receiving shell 6 drives the intermediate shell 5 to rotate. The intermediate shell 5 drives the power shell 4 to rotate synchronously through the first interlocking part 7 and the second interlocking part 8 that are interlocked with each other, and the power shell 4 drives the rotor of the generator 3 to rotate, thereby generating electricity. If the rotor resistance of the generator 3 is too large or stuck during the initial startup, and the fastening force between the first interlocking part 7 and the second interlocking part 8 is insufficient to drive the intermediate shell 5 to rotate, the first interlocking part 7 will squeeze the adjacent second interlocking part 8, causing it to move to the right, thereby causing the second interlocking part 8 to move to the right. A fitting part 7 is disengaged from the adjacent second fitting part 8 (i.e., the crankshaft and the rotor lose power connection), and the tension spring 11 is stretched and tightened simultaneously. As the first fitting part 7 passes over the adjacent second fitting part 8, the second fitting part 8 moves to the left and resets under the drive of the tension spring 11. The second fitting part 8 continues to rotate and contacts the next first fitting part 7, thereby "loosening" the generator rotor again through the mutual squeezing of the two (i.e., attempting to perform intermittent "soft impact" on the rotor in the circumferential direction to prevent the lubricating oil from being overcooled and "frozen"). If the lubricating oil in the motor is restored, normal power generation will be carried out.

[0025] During high-speed rotation, the fixing frame 9 drives the four centrifugal blocks 13 to move in the direction away from the axis of the transfer shell 5, and synchronously squeezes the spring between the centrifugal blocks 13 and the fixing frame 9. If the crankshaft or rotor suddenly gets stuck, the first insert 7 squeezes the second insert 8 to move to the right, and the second insert 8 drives the fixing frame 9 and the four centrifugal blocks 13 thereon to move to the right. The centrifugal blocks 13 squeeze and drive the two adjacent limit members 15 away from each other, and at the same time stretch the tension spring between the two limit members 15 until the cylindrical part of the centrifugal block 13 is embedded in the through hole on the limit member 15, thereby preventing the second insert 8 from resetting to the left. At this time, the power connection between the crankshaft of the diesel engine 2 and the generator 3 is completely disconnected, thereby preventing the jamming from causing irreversible damage to the crankshaft or rotor. Then find a technician to perform maintenance. After the maintenance is completed, reset the various parts of the device to facilitate subsequent continued use.

[0026] Example 2

[0027] This embodiment discloses a high-efficiency diesel generator set, which is further improved on the basis of the first embodiment.

[0028] The structure, connection relationship and working process of the diesel generator set in Example 1 will not be described in detail. The working principle of the following structure will be explained in detail, and the same applies to subsequent embodiments.

[0029] like Figure 4 、 Figure 7 and Figure 8As shown, it also includes a flexible driving mechanism for preventing jamming during initial startup. The flexible driving mechanism is arranged on the intermediate shell 5. The flexible driving mechanism includes a stirring member 16 distributed in a circumferential array. The stirring members 16 distributed in the circumferential array are all slidably and rotatably connected to the intermediate shell 5. A fan blade for driving the fluid flow in the power shell 4 is provided on the left side of the stirring member 16. The receiving shell 6 is slidably connected with a first sliding ring 17. The second fitting 8 passes through the first sliding ring 17. The stirring members 16 distributed in the circumferential array are all rotatably connected to the first sliding ring 17. A transmission groove 171 distributed in a circumferential array is provided in the power shell 4. The transmission groove 171 is an L-shaped groove for cooperating with the fan blades of the stirring member 16 for transmission. A tension spring is provided between the first sliding ring 17 and the intermediate shell 5, and the tension spring between the two is initially in a stretched state. A limiting component for limiting the position of the first sliding ring 17 is provided on the intermediate shell 5.

[0030] like Figure 8 and Figure 10 As shown, the limiting assembly includes four limiting blocks 18 distributed in a circumferential array. The limiting blocks 18 distributed in the circumferential array are all slidably connected to the intermediate shell 5. An inclined surface is provided on the side of the limiting block 18 away from the axis of the intermediate shell 5. The limiting block 18 is used to limit the first sliding ring 17. A return spring 19 is provided between the limiting block 18 and the intermediate shell 5. The elastic force provided by the return spring 19 is greater than the tension of the tension spring between the first sliding ring 17 and the intermediate shell 5. A trigger assembly for changing the position of the limiting block 18 is provided on the receiving shell 6. The trigger assembly includes four traction ropes 20 distributed in a circumferential array. The traction ropes 20 are made of soft and non-stretchable material. The four traction ropes 20 are respectively fixed to the side of the adjacent limiting block 18 close to the intermediate shell 5. The receiving shell 6 is slidably connected to the second sliding ring 21. Before the centrifugal block 13 moves to align with the corresponding two limiting members 15 due to centrifugal force, the centrifugal block 13 can contact and push the second sliding ring 21, and the traction rope 20 is fixed to the second sliding ring 21.

[0031] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: Figure 4As an example) in the above embodiment, when the resistance is too large or stuck during the initial startup of the whole, the second insert 8 is squeezed by the first insert 7, driving the fixed frame 9 and the four centrifugal blocks 13 thereon to move to the right together. The cylindrical part of the centrifugal block 13 squeezes and drives the second sliding ring 21 to move to the right. The second sliding ring 21 drives the four limit blocks 18 to move toward the axis of the intermediate shell 5 through the traction rope 20, and at the same time squeezes the return spring 19, so that the tension spring between the first sliding ring 17 and the intermediate shell 5 drives the first sliding ring 17 and the stirring member 16 thereon to move to the left. After the stirring member 16 moves to the left, it drives the fluid in the power shell 4 to rotate. The fluid in the power shell 4 performs a circumferential continuous flexible impact on the power shell 4 through the transmission groove 171, which is also used to prevent the initial load from being too large at startup from generating excessive load on the first insert 7 and the second insert 8. When friction occurs between the first insert 7 and the second insert 8, the fluid in the power shell 4 can also dissipate heat. If the lubricating oil in the motor is restored, the second insert 8 drives the first insert 7 Rotate to generate electricity normally.

[0032] Example 3

[0033] This embodiment discloses a high-efficiency diesel generator set, which is further improved on the basis of the second embodiment.

[0034] like Figure 8 and Figure 9 As shown, it also includes a slow-reset mechanism for slowly resetting the second fitting 8. The slow-reset mechanism is arranged on the intermediate shell 5. The slow-reset mechanism includes four buffer shells 22 distributed in a circumferential array. The four buffer shells 22 are all fixed to the intermediate shell 5. The buffer shell 22 is slidably connected to the connecting rod 23 and the resistance plate 24. There is a dynamic seal between the buffer shell 22 and the connecting rod 23. The buffer shell 22 is filled with a buffer fluid. The connecting rod 23 is fixed to the fixing frame 9. The resistance plate 24 is provided with six through holes distributed in a circumferential array. One-way valves are provided in three through holes on the resistance plate 24, and the through holes with one-way valves are spaced apart from the through holes without one-way valves. The flow direction of the one-way valve is only from back to front ( Figure 9 direction), the through holes distributed in the circumferential array on the resistance plate 24 are all fan-shaped, and the center of the circle corresponding to the fan-shaped is located on the central axis of the resistance plate 24. The area change of the fan-shaped through holes is the same as the area change of the resistance plate 24, and both gradually increase from the inside to the outside, which is used to ensure that the resistance plate 24 is evenly stressed when providing resistance, thereby improving the service life of the resistance plate 24 and the connecting rod 23.

[0035] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: Figure 4For example, when the first insert 7 squeezes the second insert 8 and the fixing frame 9 to move to the right, the buffer fluid in the buffer shell 22 flows leftward to the left side of the resistance plate 24 through the through holes and the one-way valve on the resistance plate 24. When the fastening spring 11 drives the fixing frame 9 and the second insert 8 to reset, the buffer fluid on the left side of the resistance plate 24 can only flow to the right side of the resistance plate 24 through the three through holes, thereby extending the reset time of the second insert 8, and extending the time for the fluid in the power shell 4 in the above-mentioned embodiment 2 to perform a circumferential continuous flexible impact on the power shell 4 through the transmission groove 171.

[0036] Example 4

[0037] This embodiment discloses a high-efficiency diesel generator set, which is further improved on the basis of the third embodiment.

[0038] like Figure 8 and Figure 10 As shown, it also includes an angle adjustment mechanism for controlling the rotation of the agitator 16. The angle adjustment mechanism is arranged on the first sliding ring 17. The angle adjustment mechanism includes a ring gear 25. The ring gear 25 is rotatably connected to the first sliding ring 17. A hexagonal block for easy rotation is installed on one of the agitators 16. A gear 27 is provided on the agitator 16. The gear 27 is meshed with the ring gear 25. A locking component for locking the rotation angle of the ring gear 25 is provided on the first sliding ring 17.

[0039] like Figure 10 and Figure 11 As shown, the locking assembly includes a rotating shell 28, which is fixed to the front side of the first sliding ring 17 ( Figure 10 In the direction shown), the rotating shell 28 is slidably connected to the limit frame 29, and a tension spring is provided between the rotating shell 28 and the limit frame 29. The limit frame 29 is used to limit the ring gear 25. The tension spring between the rotating shell 28 and the limit frame 29 is used to ensure that the limit frame 29 is in contact with the ring gear 25. When the limit frame 29 is no longer needed to limit the ring gear 25, the limit frame 29 is pulled, and at the same time, the tension spring between the limit frame 29 and the rotating shell 28 is pulled until the limit frame 29 loses its limit on the ring gear 25.

[0040] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: before installing the receiving shell 6, if it is necessary to adjust the inclination angle of the fan blades on the stirring member 16 (the inclination angle affects the stirring intensity of the fluid in the power shell by the fan blades on the stirring member 16, that is, affects the power transmission efficiency), first pull the limit frame 29 to make the limit frame 29 lose the limit on the ring gear 25, and at the same time stretch the tension spring between the rotating shell 28 and the limit frame 29, then rotate the stirring member 16 through the hexagonal block on the stirring member 16, and the gear 27 on the stirring member 16 drives the remaining stirring members through the ring gear 25. 16 rotates together. When the angle of the agitator 1 is adjusted, the limit frame 29 is released, and the tension spring between the rotating shell 28 and the limit frame 29 drives the limit frame 29 to reset, thereby limiting the ring gear 25. At this time, the angle of the agitator 16 is adjusted, preventing the subsequent agitator 16 from affecting the state of the agitator 16 when driving the fluid to transmit power. The inclination state of the agitator 16 is adjusted according to needs through the cooperation of the ring gear 25 and the gear 27. After the adjustment is completed, the inclination angle of the agitator 16 is locked by the limit frame 29, which improves the scope of use of the device.
