Description

Technical Field

[0001] This invention relates to the field of diesel generator set technology, and in particular to a high-efficiency diesel generator set. Background Technology

[0002] A diesel generator consists of two parts: a diesel engine and a generator. The engine generates a high-temperature, high-pressure environment using compressed air, injecting diesel fuel into the cylinder and igniting it. The energy from combustion drives the piston to do work, rotating the crankshaft. The generator then uses the mechanical energy of the crankshaft to drive the rotor, converting the mechanical energy into electrical energy through electromagnetic induction, thus outputting alternating current. It features high efficiency, high reliability, rapid start-up, and wide adaptability, and is widely used in backup power, emergency power supply, construction sites, and remote areas.

[0003] Existing technologies typically connect the diesel engine crankshaft to the generator rotor via a coupling. If the generator rotor suddenly jams due to poor lubrication (due to various reasons, such as the increased viscosity of lubricating oil in cold regions, leading to increased rotor rotation resistance), the increased rotor rotation resistance will, according to Newton's third law (action and reaction), generate a reaction torque on the diesel engine driving it. This reaction torque is opposite in direction to the engine's output driving torque. This increased reaction torque will be directly and completely transmitted back to the diesel engine crankshaft. Consequently, the diesel engine will not only have to overcome the load torque required for normal generator operation at room temperature, but also the additional resistance torque generated by the high-viscosity engine oil. This significantly increases the actual output load of the diesel engine, leading to increased stress on internal components during engine startup, thus increasing the risk of damage. In severe cases (seizure), it may even cause irreversible damage to the crankshaft or rotor. Summary of the Invention

[0004] To overcome the above problems, the present invention provides a high-efficiency diesel generator set.

[0005] Technical solution: A high-efficiency diesel generator set includes a frame, on which a diesel engine and a generator are fixedly connected.

[0009] Preferably, the system also includes a flexible drive mechanism to prevent jamming during initial startup.

Detailed Implementation

[0029] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may 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 to fully convey the scope of the invention to those skilled in the art.

[0030] Example 1

[0031] This embodiment discloses a high-efficiency diesel generator set, which is used to prevent the power connection between the crankshaft and rotor from failing when the generator load is too high or the crankshaft, rotor, etc. suddenly seize, so as to prevent greater damage.

[0032] like Figures 1-5As 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 fixedly connected to the frame 1. The turbine mounted 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 stable rotation, maintaining stable intake pressure, ensuring efficient operation of the diesel engine 2, and reducing the probability of incomplete combustion of fuel, thus achieving energy saving and emission reduction. The rotor of the generator 3 is fixedly connected to a power housing 4, and the power housing 4 is rotatably and sealed to a transfer housing 5. The power housing 4 and the transfer housing 5... Both are equipped with through holes, allowing the power housing 4 and the transfer housing 5 to be rigidly connected with bolts in an emergency to maintain power transmission. The space between the power housing 4 and the transfer housing 5 is filled with a fluid for transmission (this fluid has antifreeze properties). A receiving housing 6 is fixedly connected to the transfer housing 5, and the crankshaft of the diesel engine 2 is fixedly connected to the receiving housing 6. The receiving housing 6 is also a high-strength steel structure to ensure stable transmission under high-intensity rotation. The power housing 4 is equipped with a fitting unit to ensure transmission safety; the fitting unit includes four first fitting members 7 arranged in a circumferential array, and four second fitting members 7... Each of the first and second fittings 7 is fixedly connected to the power housing 4. Four second fittings 8, arranged in a circumferential array, are slidably connected to the transfer housing 5. Each second fitting 8 has a limit ring to restrict its sliding range and ensure stable contact between the first and second fittings 7 and 8. Both the first and second fittings 7 and 8 have two mirror-image inclined surfaces that interlock (V-shaped). The angle between the two inclined surfaces on the first fitting 7 is obtuse. All four second fittings 8 are fixedly connected to a fixing frame 9. Located inside the receiving shell 6, a sliding frame 10 is slidably connected to the fixed frame 9. A fastening spring 11 is fixed between the sliding frame 10 and the transfer shell 5. The fastening spring 11 is a tension spring, used to provide fastening force between the first fitting 7 and the second fitting 8. An adjusting rod 12 that is rotatably connected to the sliding frame 10 is threaded onto the fixed frame 9. Before use, the tension of the fastening spring 11 can be adjusted according to the power and load parameters of the diesel engine and generator (i.e., the tension provided by the fastening spring 11). A high-speed limiting mechanism for protecting the drive shaft is provided on the fixed frame 9.

[0033] like Figures 4-6As shown, the high-speed limiting mechanism includes four centrifugal blocks 13 arranged in a circumferential array. Each centrifugal block 13 consists of a rectangular block and a round rod, with the round rod having two mirror-distributed inclined surfaces. All four centrifugal blocks 13 are slidably connected to the fixed frame 9. A spring is provided between the centrifugal blocks 13 and the fixed frame 9. When the diesel generator starts, the four centrifugal blocks 13 rotate together. During rotation, the centrifugal blocks 13 are moved away from the axis of the central transfer shell 5 by centrifugal force, while simultaneously compressing the adjacent spring. Four fixed plates 14 arranged in a circumferential array are fixedly attached to the receiving shell 6. Two limiting members 15 are slidably connected to the fixed plates 14, and the centrifugal blocks 13 are used to compress the corresponding two limiting members 15. The two limiting members 15 on the same fixed plate 14 have inclined surfaces on opposite sides. The limiting members 15 have through holes to limit the position of the centrifugal blocks 13. The inclination angle of the inclined surface on the limiting member 15 is the same as the inclination angle of the adjacent inclined surface of the round rod of the adjacent centrifugal block 13. A tension spring is provided between the two limiting members 15.

[0034] The working principle of a high-efficiency diesel generator set in this embodiment is as follows:

[0035] Preparation phase: (hereinafter referred to as preparation phase) Figure 4 (Taking the orientation as an example) First, lay the power housing 4 flat and inject transmission fluid into the power housing 4. Then, seal and rotate the power housing 4 and the intermediate housing 5. After the two are sealed, install the receiving housing 6 and the intermediate housing 5 and their parts on the crankshaft of the diesel engine 2 with bolts. Then, adjust the fastening force between the first fitting 7 and the second fitting 8 according to the power load of the diesel engine 2 and the generator 4: rotate the adjusting rod 12, and the adjusting rod 12 drives the sliding frame 10 to move to the right, thereby increasing the tension of the fastening spring 11 (that is, increasing the fastening force between the first fitting 7 and the second fitting 8). After the adjustment is completed, connect the receiving housing 6 to the right side of the intermediate housing 5 with bolts. Then connect the generator 3 rotor to the right side of the receiving housing 6 with bolts. At this time, the preparation is completed.

[0036] Working Phase: After preparation, start diesel engine 2. The crankshaft of diesel engine 2 drives the receiving housing 6 to rotate, which in turn drives the intermediate housing 5 to rotate. The intermediate housing 5, through the interlocking first fitting 7 and second fitting 8, drives the power housing 4 to rotate synchronously. The power housing 4 drives the rotor of generator 3 to rotate, thereby generating electricity. If the rotor resistance of generator 3 is too high or jammed during initial startup, and the fastening force between the first fitting 7 and the second fitting 8 is insufficient to drive the intermediate housing 5 to rotate, the first fitting 7 will press against the adjacent second fitting 8, causing it to move to the right, thus allowing the intermediate housing 5 to rotate. The first fitting 7 disengages from the adjacent second fitting 8 (i.e., the crankshaft and rotor lose power connection) and simultaneously stretches and tightens the tension spring 11. As the first fitting 7 passes the adjacent second fitting 8, the second fitting 8 moves to the left and resets under the action of the tension spring 11. The second fitting 8 continues to rotate and contacts the next first fitting 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 "frozen" due to excessive cold). After the lubricating oil in the motor is restored, normal power generation is carried out.

[0037] During high-speed rotation, the fixed frame 9 drives the four centrifugal blocks 13 to move away from the axis of the central rotating shell 5, simultaneously compressing the spring between the centrifugal blocks 13 and the fixed frame 9. If the crankshaft or rotor suddenly jams, the first fitting 7 compresses the second fitting 8 to move to the right. The second fitting 8 drives the fixed frame 9 and its four centrifugal blocks 13 to move to the right. The centrifugal blocks 13 compress and drive the two adjacent limiting pieces 15 away from each other, while stretching the tension spring between the two limiting pieces 15 until the cylindrical part of the centrifugal block 13 is embedded in the through hole on the limiting piece 15, thereby preventing the second fitting 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 irreversible damage to the crankshaft or rotor caused by jamming. Then, technicians are called to carry out maintenance. After maintenance, all parts of this device are reset to facilitate continued use.

[0038] Example 2

[0039] This embodiment discloses a high-efficiency diesel generator set, which is a further improvement on the basis of Embodiment 1.

[0040] The structure, connection relationship and working process of the diesel generator set in Example 1 will not be described again. The working principle of the following structure will be explained in detail. The same applies to subsequent examples.

[0041] like Figure 4 , Figure 7 and Figure 8As shown, it also includes a flexible drive mechanism for preventing jamming during initial startup. The flexible drive mechanism is mounted on the transfer shell 5 and includes circumferentially arrayed agitators 16. The circumferentially arrayed agitators 16 are all slidably and rotatably connected to the transfer shell 5. A fan blade is provided on the left side of the agitator 16 to drive the fluid flow in the power shell 4. A first sliding ring 17 is slidably connected to the receiving shell 6. A second fitting 8 passes through the first sliding ring 17. The circumferentially arrayed agitators 16 are all rotatably connected to the first sliding ring 17. A circumferentially arrayed transmission groove 171 is provided in the power shell 4. The transmission groove 171 is an L-shaped groove used to cooperate with the fan blade of the agitator 16 for transmission. A tension spring is provided between the first sliding ring 17 and the transfer shell 5, and the tension spring between the two is initially in a stretched state. A limiting component is provided on the transfer shell 5 to limit the position of the first sliding ring 17.

[0042] like Figure 8 and Figure 10 As shown, the limiting component includes four limiting blocks 18 arranged in a circumferential array. The limiting blocks 18 are all slidably connected to the transfer shell 5. An inclined surface is provided on the side of the limiting block 18 away from the axis of the transfer 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 transfer 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 transfer shell 5. A triggering component for changing the position of the limiting block 18 is provided on the receiving shell 6. The triggering component includes four traction ropes 20 arranged 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 near the transfer shell 5. A second sliding ring 21 is slidably connected to the receiving shell 6. Before the centrifugal block 13 moves to align with the corresponding two limiting components 15 due to centrifugal force, the centrifugal block 13 can contact and push the second sliding ring 21. The traction ropes 20 are fixed to the second sliding ring 21.

[0043] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: (hereinafter referred to as...) Figure 4(Taking the orientation as an example) In the above embodiment, when the resistance is too high or the machine jams during the initial start-up, the second fitting 8 is squeezed by the first fitting 7, causing the fixed frame 9 and its four centrifugal blocks 13 to move to the right. 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 limiting blocks 18 to move towards the axis of the transfer 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 transfer shell 5 drives the first sliding ring 17 and its agitator 16 to move to the left. After the agitator 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 continuous circumferential 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 and causing excessive load on the first fitting 7 and the second fitting 8. When friction occurs between the first fitting 7 and the second fitting 8, the fluid in the power shell 4 can also dissipate heat. If the lubricating oil in the motor is restored, the second fitting 8 drives the first fitting 7 to move. It rotates, thus generating electricity normally.

[0044] Example 3

[0045] This embodiment discloses a high-efficiency diesel generator set, which is a further improvement on the basis of Embodiment 2.

[0046] 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 disposed on the transfer shell 5 and includes four buffer shells 22 arranged in a circumferential array. The four buffer shells 22 are all fixed to the transfer shell 5. The buffer shells 22 are slidably connected to the connecting rod 23 and the resistance plate 24. There is a dynamic seal between the buffer shells 22 and the connecting rod 23. The buffer shells 22 are filled with buffer fluid. The connecting rod 23 is fixed to the fixing frame 9. The resistance plate 24 is provided with six through holes arranged in a circumferential array. Three through holes on the resistance plate 24 are provided with one-way valves. The through holes with one-way valves and the through holes without one-way valves are spaced apart. The flow direction of the one-way valves is that the flow can only be from back to front. Figure 9 (Direction), the through holes distributed in the circumferential array of the resistance plate 24 are all fan-shaped, and the center of the circle corresponding to the fan shape is located on the central axis of the resistance plate 24. The area change of the fan-shaped through hole is the same as the area change of the resistance plate 24, which gradually increases from the inside to the outside. This is to ensure that the resistance plate 24 is subjected to uniform force when providing resistance, thereby improving the service life of the resistance plate 24 and the connecting rod 23.

[0047] The working principle of a high-efficiency diesel generator set in this embodiment is as follows: (hereinafter referred to as...) Figure 4(Taking the orientation as an example) When the first fitting 7 squeezes the second fitting 8 and the fixing frame 9 to move to the right, the buffer fluid in the buffer shell 22 flows to the left side of the resistance plate 24 through the through hole and the one-way valve on the resistance plate 24. When the fastening spring 11 drives the fixing frame 9 and the second fitting 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 prolonging the reset time of the second fitting 8. This prolongs the time for the fluid in the power shell 4 in the above embodiment 2 to perform continuous circumferential flexible impact on the power shell 4 through the transmission groove 171.

[0048] Example 4

[0049] This embodiment discloses a high-efficiency diesel generator set, which is a further improvement on the basis of Embodiment 3.

[0050] 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 disposed on the first sliding ring 17. The angle adjustment mechanism includes a gear ring 25, which is rotatably connected to the first sliding ring 17. One of the agitators 16 is equipped with a hexagonal block that is easy to rotate. The agitator 16 is provided with a gear 27, which meshes with the gear ring 25. The first sliding ring 17 is provided with a locking component for locking the rotation angle of the gear ring 25.

[0051] like Figure 10 and Figure 11 As shown, the locking assembly includes a rotating housing 28, which is fixed to the front side of the first sliding ring 17. Figure 10 (As shown in the direction), the rotating shell 28 is slidably connected to the limiting frame 29. A tension spring is provided between the rotating shell 28 and the limiting frame 29. The limiting frame 29 is used to limit the gear ring 25. The tension spring between the rotating shell 28 and the limiting frame 29 is used to ensure that the limiting frame 29 is in contact with the gear ring 25. When the limiting frame 29 is not needed to limit the gear ring 25, the limiting frame 29 is pulled, and at the same time the tension spring between the limiting frame 29 and the rotating shell 28 is pulled until the limiting frame 29 loses its limit on the gear ring 25.

[0052] 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 tilt angle of the fan blades on the agitator 16 (this tilt angle affects the agitation force of the fan blades on the agitator 16 on the fluid inside the power shell, that is, affects the power transmission efficiency), first pull the limit bracket 29 so that the limit bracket 29 loses its limit on the gear ring 25, and at the same time stretch the tension spring between the rotating shell 28 and the limit bracket 29. Then, the agitator 16 is rotated by the hexagonal block on the single agitator 16, and the gear 27 on the agitator 16 drives the other agitators through the gear ring 25. 16 rotate together. After the angle of the agitator 1 is adjusted, the limit frame 29 is released. The tension spring between the rotating shell 28 and the limit frame 29 drives the limit frame 29 to reset, thereby limiting the gear ring 25. At this time, the angle of the agitator 16 is adjusted, preventing the agitator 16 from affecting the state of the agitator 16 when it drives the fluid to transmit power. The tilt state of the agitator 16 is adjusted according to the requirements by the gear ring 25 and the gear 27. After the adjustment is completed, the tilt angle of the agitator 16 is locked by the limit frame 29, which improves the application range of this device.

[0053] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
