Description

Technical Field

[0001] This invention relates to the field of energy-saving diesel generator set technology, specifically to an energy-saving diesel generator set with a vibration damping structure. Background Technology

[0002] With the continuous growth of societal demand for electricity, especially in applications involving unstable power grids or remote areas without electricity, diesel generator sets have become widely used as a reliable and efficient backup power source. A diesel generator set is a device that uses diesel fuel to generate electricity through the principle of an internal combustion engine. Its core consists of two main parts: the diesel generator set and the generator. The diesel generator set generates mechanical energy by burning diesel fuel, driving the rotor of the generator to rotate. The stator of the generator then generates alternating current as the rotor rotates.

[0003] During the operation of a diesel generator set, factors such as engine imbalance, inconsistent fuel supply, and engine rotor imbalance can cause vibrations. When the vibrations are too severe, they may damage some parts of the entire unit, reduce the unit's efficiency, and generate loud noise. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an energy-saving diesel generator set with a shock-absorbing structure, including a housing, a cabinet door hinged to the front end of the housing, a radiator tank inside the housing, a diesel engine inside the housing, and a generator inside the housing, wherein the radiator tank, the diesel engine and the generator are arranged in sequence in the middle of the interior of the housing.

[0005] Ventilation components are fixedly mounted on the housing.

[0006] The base is fixedly installed at the bottom of the housing;

[0007] The base includes a fixed plate, with a trapezoidal elastic plate fixedly connected to its top. This elastic plate maintains stable support under long-term load, reducing changes in the distance between the upper and lower plates due to excessive deformation and ensuring consistent unit installation height. Furthermore, since the box-type unit may experience lateral moments due to center-of-gravity shift during operation, the fixed plate and top plate are connected by trapezoidal elastic plates at the edges, forming an edge support structure with an elastic frame. This enhances the overall anti-tilting stability of the base and prevents the unit from tilting under sudden vibrations or external impacts. A trapezoidal ring plate is also fixedly connected to the top of the fixed plate, with its open ends facing the elastic plate. By placing multiple elastic plates at the edge of the top plate, the force on the fixed plate and top plate is mainly concentrated in the vertical direction. When subjected to vertical pressure, the inclined structure of the plate transforms the vertical impact force into a lateral dispersion force through the elastic deformation of the inclined side, achieving one-step buffering and two-stage stress relief. This design can efficiently absorb the vertical vibration generated during unit operation, reduce the transmission of vibration to the foundation below the base or the unit above, and reduce component fatigue damage caused by long-term vertical vibration. When the unit vibrates during operation, the spring plate can absorb the impact energy through the deformation of the trapezoidal inclined side, effectively weakening the transmission of vibration to the base and installation foundation. It can adapt to vibration impacts of different frequencies, reducing the risk of component loosening and wear caused by long-term vibration of the unit. A top plate is set on the top of the fixed plate, and the top plate is fixedly connected to the end of the spring plate away from the fixed plate. There are multiple spring plates, which are evenly arranged around the four edges of the top plate.

[0008] Preferably, the cabinet door has a horizontally opened round hole inside, and there are two ventilation components. The two ventilation components are located at the ends of the left and right sides of the housing. There are two fans inside the housing near the ventilation components, and the two fans are located on the left and right sides of the housing.

[0009] Preferably, the top of the top plate is fixedly connected to the bottom of the housing. The ring plate is located inside multiple spring plates. A bottom plate is provided on the top of the fixed plate. There are two bottom plates, which are fixedly connected to the opposite sides of the fixed plate and the top plate, respectively. The bottom plates are located inside the ring plate. A fixed seat is fixedly connected to the opposite side of the bottom plates. A block is provided in the middle between the fixed plate and the top plate. The block and the fixed seat are magnetic. The magnetic properties of the block and the fixed seat are the same. When the unit vibrates during operation, the edge spring plates can efficiently cope with high-frequency, small-amplitude vibrations due to their elastic deformation. The shock is quickly buffered by the dispersion force of the trapezoidal structure. The mutual repulsion between the central spring and the block and the fixed seat absorbs low-frequency, large-amplitude vibrations, such as the overall shaking during unit startup or sudden load changes. The internal properties of the material are utilized. Friction converts vibration energy into heat energy, and the combination of the two can cover the main vibration frequency bands during unit operation, improve the overall vibration reduction effect, reduce the impact of vibration on the base and surrounding equipment, and the edge spring plate can cut off some of the solid vibration sound waves transmitted along the edge of the base, reducing resonance noise. The central spring can effectively attenuate the low-frequency vibration noise transmitted from the core components of the unit to the base, and reduce the vibration radiation at the contact point between the base and the foundation. The synergistic effect of the two can reduce the overall noise level of the unit during operation. The block is elliptical, and there are two sliding rods fixedly connected to the ends of the block. The two sliding rods are symmetrically arranged at both ends of the long side of the block. The end of the sliding rod away from the block is slidably connected to the fixed seat. A spring is sleeved on the outside of the block, and the two ends of the spring are fixedly connected to the two base plates.

[0010] Preferably, the housing includes a box body, which is fixedly connected to the top of the top plate. A through hole is provided at the front end of the box body, and a cabinet door is located inside the through hole. Two square grooves are provided at the middle of the ends of the box body, positioned on the left and right sides. A ventilation assembly is located inside the square grooves. Multiple partitions are fixedly connected to the inner wall of the box body, evenly distributed on the four sides inside the box body. Square plates are provided on the inner sides of the partitions. The box body, intermediate plate, and multiple partitions form multiple flow channels around the inner perimeter of the box body. When the cabinet door is closed, the circular hole on the door aligns with the flow channels on the side, creating a space between the box body and the intermediate plate. When the unit is running, a large amount of heat accumulates inside the intermediate plate due to the enclosed core components. The fan operates, allowing outside air to enter the box body through the ventilation assembly inside the square groove. The air then enters the gap between the intermediate plate and the box body along the chamfered edge of the intermediate plate, and is subsequently discharged from the other side. The air flowing through the gap can absorb heat through heat exchange. The heat from the surfaces of the partitions and baffles is dissipated from the right side, improving overall heat dissipation efficiency. The outer side of the square plate is fixedly connected to multiple baffles. The edge of the square plate near the fan is chamfered. There are two square plates, symmetrically arranged on the left and right sides of the enclosure. The radiator, diesel engine, and generator are located in the gap between the two square plates. The airflow from left to right can continuously remove heat from the gap space, forming a dual heat insulation mechanism of physical barrier and active heat dissipation. This can effectively reduce the surface temperature of the enclosure, prevent burns when personnel come into contact with it, and reduce the impact of the external ambient temperature on the internal components of the unit. It creates a more stable operating temperature environment for core components such as the engine and generator, ensuring their operating efficiency. At the same time, by setting baffles in the gap between the middle plate and the enclosure, the baffles can effectively prevent the heat transferred from the inner shell from spreading to the outside of the enclosure. The side of the square plate near the ventilation components is fixedly connected to the fan. There are multiple middle plates fixedly connected inside the baffles, and the multiple middle plates form a frame.

[0011] Preferably, the ventilation component includes a frame, which is fixedly installed on the box and located inside the square channel. Multiple limiting plates are fixedly connected inside the frame, arranged evenly and vertically on the inner side of the frame. When the fan operates, air enters the interior of the frame through the gap between adjacent limiting plates. Due to the diversion effect of the intermediate block, the air enters the box along the gap between the intermediate block and the limiting plates on both sides in the vertical direction. Because the channel shape is regular and the path length is consistent, the branches can maintain a stable flow velocity and advance synchronously, avoiding unilateral flow deviation or eddies. During the merging phase, the two branches, due to their consistent flow direction and balanced pressure, can smoothly merge into a single airflow, reducing energy loss caused by airflow collision. This results in a more significant improvement in overall flow efficiency compared to a design without diversion. Simultaneously, the parallel intermediate block and inclined plates form an equally spaced inclined layer structure, allowing this structure to cancel or disperse each other along parallel paths, improving the overall structure's shear resistance, reducing the risk of local deformation, and ensuring the frame maintains a stable shape under long-term dynamic loads. The ends of the limiting plates are fixedly connected to inclined plates. There are multiple inclined plates, evenly distributed inside the frame. The inclined plates slope from the outside to the inside of the frame, from bottom to top. A baffle is fixedly connected to the end of each inclined plate away from the limiting plate. When high-speed airflow enters the gap between two adjacent limiting plates, the middle block initially bears part of the impact force. Through flow diversion, the concentrated impact is converted into two dispersed lateral forces, which are then transmitted to the inclined plates on both sides. This distributed force-relieving mechanism reduces the stress on a single inclined plate, minimizing plate deformation or loosening of connections due to long-term impact. Simultaneously, the flow diversion... During the merging process, the kinetic energy of the airflow is guided in an orderly manner, avoiding the impact of violent turbulence on the internal structure of the frame and extending the service life of the equipment. The baffle is located on the side of the frame closer to the fan, and a middle block is fixedly connected to the inner side of the frame. The middle block is located at the interval between the two inclined plates. An arc-shaped groove is opened on the side of the middle block closer to the limiting plate. By opening an arc-shaped groove and a baffle on the middle block, when the airflow encounters the arc-shaped groove and the baffle, impurities will be intercepted due to inertial impact on the surface of the baffle and the arc-shaped groove, effectively preventing them from polluting the environment or entering subsequent equipment after being discharged with the airflow.

[0012] This invention provides an energy-saving diesel generator set with a vibration-damping structure. It has the following beneficial effects:

[0013] I. This energy-saving diesel generator set with a vibration damping structure has multiple spring plates at the edge of the top plate. The force on the fixed plate and the top plate is mainly concentrated in the vertical direction. When the inclined structure of the trapezoidal spring plate is subjected to vertical pressure, it will convert the vertical impact force into lateral dispersion force through the elastic deformation of the inclined side, realizing one-step buffering and two-stage stress relief. This design can efficiently absorb the vertical vibration generated during the operation of the unit, reduce the transmission of vibration to the foundation below the base or the unit above, and reduce component fatigue damage caused by long-term vertical vibration.

[0014] Second, this energy-saving diesel generator set with a shock-absorbing structure can maintain stable elastic support under long-term load conditions through elastic plates, reducing changes in the distance between the upper and lower plates due to excessive deformation, ensuring the consistency of the unit's installation height. Furthermore, since the box-type unit may generate lateral torque due to the shift of the center of gravity during operation, the fixed plate and the top plate are connected by edge trapezoidal elastic plates to form an edge support structure of elastic frame, which enhances the overall anti-tilting stability of the base and prevents the unit from tilting under sudden vibration or external impact.

[0015] Third, this energy-saving diesel generator set with a shock-absorbing structure can continuously remove heat from the space through the left and right airflow, forming a dual heat insulation mechanism of physical barrier and active heat dissipation. This can effectively reduce the surface temperature of the enclosure, prevent burns when personnel come into contact with it, and reduce the impact of the external ambient temperature on the internal components of the unit. It creates a more stable operating temperature environment for core components such as the engine and generator, ensuring their operating efficiency.

[0016] Fourth, this energy-saving diesel generator set with a shock-absorbing structure forms an equally spaced inclined layer structure through parallel intermediate blocks and inclined plates. This structure can cancel or disperse each other along parallel paths, improving the overall structure's shear resistance, reducing the risk of local deformation, and allowing the frame to maintain a stable shape under long-term dynamic loads.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] First embodiment, such as Figures 1 to 7 As shown, the present invention provides a technical solution: an energy-saving diesel generator set with a shock-absorbing structure, including a housing 2, a cabinet door 3 connected to the front end of the housing 2 by a hinge, a cooling water tank 5 inside the housing 2, a diesel engine 6 inside the housing 2, and a generator 7 inside the housing 2, wherein the cooling water tank 5, the diesel engine 6 and the generator 7 are arranged in sequence in the middle of the interior of the housing 2.

[0033] Ventilation component 4 is fixedly installed on housing 2;

[0034] Base 1 is fixedly installed at the bottom of housing 2;

[0035] The base 1 includes a fixed plate 11, with a spring plate 12 fixedly connected to the top of the fixed plate 11. The spring plate 12 is trapezoidal in shape, and its elasticity allows it to maintain stable elastic support under long-term load-bearing conditions, reducing changes in the distance between the upper and lower plates due to excessive deformation and ensuring the consistency of the unit's installation height. Furthermore, since the box-type unit may experience lateral torque due to center of gravity shift during operation, the fixed plate 11 and the top plate 14 are connected by the edge trapezoidal spring plates 12, forming an edge support structure with an elastic frame. This enhances the overall anti-tilting stability of the base 1 and prevents the unit from tilting under sudden vibrations or external impacts. A ring plate 13 is fixedly connected to the top of the fixed plate 11. The ring plate 13 is trapezoidal in shape, and its open end is opposite to that of the spring plate 12. By setting multiple spring plates 12 at the edge of the top plate 14, the force on the fixed plate 11 and the top plate 14 is mainly concentrated vertically. In the vertical direction, the inclined structure of the trapezoidal spring plate 12, when subjected to vertical pressure, will convert the vertical impact force into a lateral dispersion force through the elastic deformation of the inclined side, achieving one-step buffering and two-stage stress relief. This design can efficiently absorb the vertical vibration generated during unit operation, reduce the transmission of vibration to the foundation below the base 1 or the unit above, and reduce component fatigue damage caused by long-term vertical vibration. When the unit vibrates during operation, the spring plate 12 can absorb the impact energy through the deformation of the trapezoidal inclined side, effectively weakening the transmission of vibration to the base and the installation foundation. It can adapt to vibration impacts of different frequencies, reducing the risk of component loosening and wear caused by long-term vibration of the unit. The top plate 14 is provided on the top of the fixed plate 11. The top plate 14 is fixedly connected to the end of the spring plate 12 away from the fixed plate 11. There are multiple spring plates 12, which are evenly arranged around the four edges of the top plate 14.

[0036] The cabinet door 3 has a horizontally opened round hole inside. There are two ventilation components 4, which are located at the ends of the left and right sides of the housing 2. There are two fans 8 inside the housing 2 near the ventilation components 4, which are located on the left and right sides of the housing 2.

[0037] The top of the top plate 14 is fixedly connected to the bottom of the housing 2. The ring plate 13 is located inside the multiple spring plates 12. The top of the fixed plate 11 is provided with a bottom plate 15. There are two bottom plates 15, which are fixedly connected to the opposite sides of the fixed plate 11 and the top plate 14, respectively. The bottom plates 15 are located inside the ring plate 13. The opposite sides of the bottom plates 15 are fixedly connected with fixed seats 16. A block 19 is provided in the middle between the fixed plate 11 and the top plate 14. The block 19 is magnetic, and the fixed seat 16 is magnetic. The magnetic properties of the block 19 and the fixed seat 16 are the same. When the unit vibrates during operation, the edge spring plates 12 can efficiently cope with high-frequency, small-amplitude vibrations by means of elastic deformation. The shock is quickly buffered by the dispersion force of the trapezoidal structure. The mutual repulsion between the middle spring 17 and the block 19 and the fixed seat 16 absorbs low-frequency, large-amplitude vibrations, such as the overall shaking when the unit starts up or the load changes suddenly. The internal friction of the material is used to convert vibration energy into heat energy. The combination of the two can cover the main vibration frequency bands in the operation of the unit, improve the overall vibration reduction effect, reduce the impact of vibration on the base 1 and surrounding equipment, and the edge spring plate 12 can cut off some of the solid vibration sound waves transmitted along the edge of the base, reducing resonance noise. The central spring can effectively attenuate the low-frequency vibration noise transmitted from the core components of the unit to the base 1, and reduce the vibration radiation at the contact point between the base 1 and the foundation. The synergistic effect of the two can reduce the overall noise level of the unit during operation. The block 19 is elliptical, and the ends of the block 19 are fixedly connected to the slide rods 18. There are two slide rods 18, which are symmetrically arranged at both ends of the long side of the block 19. The end of the slide rod 18 away from the block 19 is slidably connected to the fixed seat 16. The outer side of the block 19 is fitted with a spring 17, and the two ends of the spring 17 are fixedly connected to the two base plates 15.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 8 to 10As shown, the housing 2 includes a box body 21, which is fixedly connected to the top of the top plate 14. A through hole 22 is provided at the front end of the box body 21, and a cabinet door 3 is located inside the through hole 22. Two square grooves 23 are provided at the middle of the end of the box body 21, and these two grooves are located on the left and right sides of the box body 21. A ventilation assembly 4 is located inside the square grooves 23. Multiple partitions 26 are fixedly connected to the inner wall of the box body 21, and these partitions 26 are evenly distributed on the four sides inside the box body 21. Square plates 24 are provided on the inner side of each partition 26. The intermediate plate 25 and multiple partitions 26 form multiple flow channels on the four sides of the interior of the housing 21. When the operator closes the cabinet door 3, the circular hole on the cabinet door 3 is aligned with the flow channels on the side. At this time, a space is formed between the housing 21 and the intermediate plate 25. When the unit is running, a large amount of heat will accumulate inside the intermediate plate 25 due to the core components being enclosed. The fan 8 will work, allowing outside air to enter the interior of the housing 21 through the ventilation component 4 inside the square slot 23. Thus, the air enters the gap between the intermediate plate 25 and the housing 21 along the chamfered edge of the side of the intermediate plate 25, and then the air is discharged from the other side, flowing through the gap. The circulating air absorbs heat from the surfaces of the intermediate plate 25 and partition 26 through heat exchange and is discharged from the right side, improving overall heat dissipation efficiency. The outer side of the square plate 24 is fixedly connected to multiple partitions 26. The edge of the square plate 24 near the fan 8 is chamfered. There are two square plates 24, symmetrically arranged on the left and right sides of the housing 21. The radiator 5, diesel engine 6, and generator 7 are located in the gap between the two square plates 24. The air flowing from left to right continuously carries away the heat in the gap space, forming a dual heat insulation mechanism of physical barrier and active heat dissipation, thereby achieving... The surface temperature of the enclosure 21 is reduced to prevent burns to personnel. It also reduces the impact of ambient temperature on the unit's interior, creating a more stable operating temperature environment for core components such as the engine and generator, ensuring their operating efficiency. Meanwhile, by setting a partition 26 between the intermediate plate 25 and the enclosure 21, the partition can effectively block the heat transferred from the inner shell from spreading to the outside of the enclosure. The square plate 24 is fixedly connected to the fan 8 on the side near the ventilation component 4. The partition 26 is fixedly connected to the intermediate plate 25. There are multiple intermediate plates 25, and the multiple intermediate plates 25 form a frame.

[0039] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 11 to 13As shown, the ventilation assembly 4 includes a frame 41, which is fixedly installed on the housing 21. The frame 41 is located inside the square groove 23. Limiting plates 42 are fixedly connected inside the frame 41. Multiple limiting plates 42 are evenly and vertically arranged on the inner side of the frame 41. When the fan 8 operates, air enters the interior of the frame 41 through the gap between adjacent limiting plates 42. Under the diversion effect of the intermediate block 43, the air enters the interior of the housing 21 along the gap between the intermediate block 43 and the limiting plates 42 on both vertical sides. Because the channel shape is regular and the path length is consistent, the support... The flow maintains a stable velocity and propagates synchronously, avoiding unilateral flow deviation or eddy currents. During the merging phase, the two branches, due to their consistent flow direction and balanced pressure, can smoothly merge into a single airflow, reducing energy loss caused by airflow collision. This results in a more significant improvement in overall flow efficiency compared to a design without branching. Simultaneously, the parallel intermediate blocks 43 and inclined plates 44 form an equally spaced inclined layer structure, allowing this structure to cancel or disperse each other along parallel paths, enhancing the overall structure's shear resistance, reducing the risk of local deformation, and ensuring the frame 41 maintains a stable shape under long-term dynamic loads. The end of the limiting plate 42 is fixedly connected to the inclined plate 44. There are multiple inclined plates 44 evenly distributed inside the frame 41. The inclined direction of the inclined plates 44 is from the outside to the inside of the frame 41, from bottom to top. A baffle 45 is fixedly connected to the end of the inclined plate 44 away from the limiting plate 42. When the high-speed airflow enters the gap between two adjacent limiting plates 42, the middle block 43 first bears part of the impact force and converts the concentrated impact into two dispersed lateral forces through flow diversion, which are then transmitted to the inclined plates 44 on both sides. This distributed force relief mechanism reduces the stress on a single inclined plate and reduces the deformation of the plate or loosening of the connection caused by long-term impact. At the same time, the dynamic flow of the airflow during the diversion and merging process is also reduced. It can be guided in an orderly manner, avoiding the impact of violent turbulence on the internal structure of the frame 41, and extending the service life of the equipment. The baffle 45 is located on the side of the frame 41 near the fan 8. The inner side of the frame 41 is fixedly connected to the middle block 43, which is located at the interval between the two inclined plates 44. The middle block 43 has an arc-shaped groove 46 on the side near the limiting plate 42. By having an arc-shaped groove 46 and a baffle 45 on the middle block 43, when the airflow encounters the arc-shaped groove 46 and the baffle 45, impurities will be intercepted due to inertial impact on the surface of the baffle 45 and the arc-shaped groove 46, effectively preventing them from polluting the environment or entering subsequent equipment after being discharged with the airflow.

[0040] When the unit vibrates during operation, the edge spring plate 12 can efficiently cope with high-frequency, low-amplitude vibrations by means of elastic deformation. The shock is quickly buffered by the dispersion force of the trapezoidal structure. The mutual repulsion between the central spring 17, the block 19, and the fixed seat 16 absorbs low-frequency, high-amplitude vibrations (such as the overall shaking when the unit starts up or the load changes suddenly). The vibration energy is converted into heat energy by the internal friction of the material. The combination of the two can cover the main vibration frequency bands in the operation of the unit and improve the overall vibration reduction effect.

[0041] The staff closes the cabinet door 3, aligning the round hole on the cabinet door 3 with the flow channel on the side. At this time, a space is formed between the housing 21 and the intermediate plate 25. When the unit is running, a large amount of heat will accumulate inside the intermediate plate 25 due to the core components being enclosed. The fan 8 will work, allowing outside air to enter the interior of the housing 21 through the ventilation component 4 inside the square slot 23. Thus, the air enters the gap between the intermediate plate 25 and the housing 21 along the chamfer on the side of the intermediate plate 25. Subsequently, the air is discharged from the other side. The air flowing in the gap can absorb the heat from the surface of the intermediate plate 25 and the partition plate 26 through heat exchange and is discharged from the right side, improving the overall heat dissipation efficiency.
