A diesel generator set with a buffer support mechanism

Abstract

This invention relates to the field of generator buffering and discloses a diesel generator set with a buffer support mechanism, including a generator set and a base mechanism disposed below the generator set. Four sets of vertical rod mechanisms are disposed above the base mechanism. The base mechanism includes a connecting seat assembly disposed below the vertical rod mechanisms, a base assembly disposed below the connecting seat assembly, and a connecting assembly disposed between the base assembly and the connecting seat assembly. A lower chamber is disposed within the base assembly, and a fixing assembly is disposed within the lower chamber. Two sets of buffer assemblies are disposed on both sides of the fixing assembly. This invention uses the downward pressure of a sliding plate to push a rotating rod to move a sliding rod within a groove, generating a damping effect through a high coefficient of friction. Simultaneously, the axial movement of the sliding rod compresses the sealed space inside the fixing plate, allowing air pressure to form a controllable airflow buffer through the exhaust port. This air-solid coupling buffering method can absorb more impact energy compared to traditional purely mechanical structures.

Description

Technical Field

[0001] This invention relates to the field of generator buffer technology, specifically to a diesel generator set with a buffer support mechanism. Background Technology

[0002] The patent application with publication number CN221524950U includes a housing, a cleaning device, a buffer structure, a diesel generator set, and a striking device. The cleaning device is located on the inside left side of the housing, the buffer structure is located at the inside bottom of the housing, the diesel generator set is located at the top of the buffer structure, and the striking device is located on the inside left side of the housing. The cleaning device consists of a support base, a motor, a rotating rod, a connecting frame, a striking plate, an outer frame, and a filter screen. The support base is fixedly installed on the inside left side of the housing, the motor is fixedly installed on the right side of the support base, and the rotating rod is fixedly installed on the output shaft of the motor. The housing structure of this diesel generator set, by being equipped with a filter screen, can filter the air entering the housing, and the surface of the filter screen has many small diameter through holes to effectively prevent rainwater from entering the device. Combined with a rain shelter, the waterproof effect is even better.

[0003] In the aforementioned patents, some existing generator set bases adopt a single-stage buffer design, such as absorbing vibration energy through springs or hydraulic dampers. However, such structures are prone to buffer failure due to excessive instantaneous impact when the unit starts up or the load changes suddenly, which may even cause damage to the support structure. In addition, traditional shock absorption structures have low efficiency in dissipating vibration energy and cannot effectively suppress the transmission of vibration to the ground or surrounding equipment, thus reducing the lifespan of key components of the generator set. Summary of the Invention

[0004] The purpose of this invention is to provide a diesel generator set with a buffer support mechanism to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a diesel generator set with a buffer support mechanism, comprising a generator set and a base mechanism disposed below the generator set, four sets of vertical rod mechanisms disposed above the base mechanism, the base mechanism including a connecting seat assembly disposed below the vertical rod mechanism, a base assembly disposed below the connecting seat assembly, a connecting assembly disposed between the base assembly and the connecting seat assembly, a lower chamber disposed inside the base assembly, a fixing assembly disposed inside the lower chamber, and two sets of buffer assemblies disposed on both sides of the fixing assembly;

[0006] The base assembly includes a base with an upper chamber on top. The connecting assembly includes a fixed plate fixedly connected to the lower part of the upper chamber. Multiple sliding grooves are respectively provided on both sides of the fixed plate. Sliding rods are slidably connected in the multiple sliding grooves. A rotating rod is rotatably connected to the other end of the sliding rod, and a connecting block is rotatably connected to the other end of the rotating rod.

[0007] Preferably, the base assembly further includes a limiting frame fixedly connected to the upper part of the upper chamber, a through hole is provided in the lower part of the upper chamber, the through hole is located directly below the fixing plate, a fixing plate is fixedly connected inside the through hole, and a plurality of exhaust holes are provided on the fixing plate.

[0008] Preferably, the connecting seat assembly includes a sliding plate slidably disposed inside the upper cavity, a connecting seat fixedly connected to the upper end of the sliding plate, and a plurality of connecting blocks fixedly connected to the lower part of the sliding plate.

[0009] Preferably, the lower chamber is located inside the lower part of the base, and the lower chamber is connected to the through hole.

[0010] Preferably, the fixing component includes a connecting ring fixedly connected to the upper part of the lower cavity, a sliding disk slidably connected inside the connecting ring, a limiting disk fixedly connected to the lower end of the sliding disk, a plurality of thick springs fixedly connected to the lower end of the limiting disk, the other end of the thick springs fixedly connected to the lower part of the lower cavity, and the connecting ring being disposed below the through hole.

[0011] Preferably, the buffer assembly includes connecting short plates fixedly connected to both sides of the limiting plate, a lower pressure plate fixedly connected to the other side of the connecting short plates, an airbag fixedly connected to the lower end of the lower pressure plate, a connecting tube connected to one side of the airbag, the connecting tube consisting of two short tubes and one long tube, a sliding rod slidably connected inside the long tube of the connecting tube, a connecting shell fixedly connected to the other end of the connecting tube, the connecting shell fixedly connected to the lower part of the lower cavity, a sliding shell slidably connected to the upper part of the connecting shell, and two springs fixedly connected between the sliding shell and the connecting shell.

[0012] Preferably, the vertical rod mechanism includes a vertical rod fixedly connected to the upper end of the connecting seat. The vertical rod has multiple regular hexagonal slots on the side facing the generator set, and the regular hexagonal slots are filled with sound-absorbing cotton. Multiple liquid injection nozzles are fixedly installed on the side of the vertical rod away from the generator set.

[0013] Preferably, the vertical rod has multiple liquid storage chambers inside, each of the injection nozzles corresponds to a liquid storage chamber, and multiple baffles are provided inside the liquid storage chamber, each of the baffles having a different shape.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0015] (1) A base assembly is installed below the generator set. The base assembly contains a connecting assembly, a lower chamber, a fixing assembly, and a buffer assembly. Through the innovative multi-stage buffer structure design, the vibration energy of the diesel generator set is efficiently dissipated. When the vibration is transmitted to the sliding plate through the connecting seat, the first-stage buffer mechanism is immediately activated. The sliding plate presses down, causing the rotating rod to push the sliding rod to move in the groove. At this time, the specially made rubber pad in the groove not only provides a sealing function, but also generates a damping effect through the high friction coefficient. At the same time, the axial movement of the sliding rod compresses the sealed space inside the fixing plate, so that the air pressure forms a controllable airflow buffer through the exhaust hole. This gas-solid coupling buffer method can absorb more impact energy than the traditional pure mechanical structure. The second-stage buffer is achieved by a coarse spring. When the compressed air pushes the sliding plate down, it squeezes the coarse spring, providing a gentle buffer in the initial stage. The third-stage liquid-gas composite buffer is achieved when the lower pressure plate synchronously compresses the air bag, pushing the damping liquid into the connecting shell through the sliding rod in the connecting pipe. The three-stage buffer system can reduce the amplitude, reduce the maximum instantaneous impact force when the generator set starts, and greatly extend the fatigue life of the key components of the generator set.

[0016] (2) The regular hexagonal groove set by the vertical rod mechanism in this invention is not a simple sound absorption structure. Its hexagonal honeycomb arrangement can form a Helmholtz resonance effect. The gradient density sound-absorbing cotton filled in the groove can achieve wide frequency sound absorption. In terms of solid sound transmission control, the damping liquid design in the liquid storage chamber breaks through the traditional single DC channel mode. Multiple irregular baffles enable the damping liquid to convert sound energy into heat energy. When the sliding plate moves down, it drives the airbags on both sides to press down synchronously through the connecting short plate, converting the vibration energy into air pressure. This air pressure pushes the slide rod through the connecting pipe to squeeze the damping liquid in the connecting shell, forcing the sliding shell to overcome the spring resistance and rise, thereby further converting the remaining vibration energy into the damping liquid flow resistance and spring deformation energy, realizing multi-level energy consumption and significantly improving the buffering and vibration reduction performance of the diesel generator set.

[0030] like Figures 1 to 10 As shown, the present invention provides a diesel generator set with a buffer support mechanism, including a generator set 1 and a base mechanism 2 disposed below the generator set 1.

[0033] The connecting seat assembly 22 includes a sliding plate 222 that is slidably disposed inside the upper chamber 213. A connecting seat 221 is fixedly connected to the upper end of the sliding plate 222, and a plurality of connecting blocks 235 are fixedly connected to the lower part of the sliding plate 222.

[0034] The lower chamber 24 is located inside the lower part of the base 211 and is connected to the through hole 214.

[0035] The fixing component 25 includes a connecting ring 251 fixedly connected to the upper part of the lower chamber 24. A sliding disk 252 is slidably connected inside the connecting ring 251. A limiting disk 253 is fixedly connected to the lower end of the sliding disk 252. A plurality of coarse springs 254 are fixedly connected to the lower end of the limiting disk 253. The other end of the coarse springs 254 is fixedly connected to the lower part of the lower chamber 24. The connecting ring 251 is located below the through hole 214.

[0036] The buffer assembly 26 includes connecting short plates 261 fixedly connected to both sides of the limiting plate 253. A pressure plate 262 is fixedly connected to the other side of the connecting short plates 261. An airbag 263 is fixedly connected to the lower end of the pressure plate 262. A connecting tube 264 is connected to one side of the airbag 263. The connecting tube 264 consists of two short tubes and one long tube. A sliding rod 265 is slidably connected inside the long tube of the connecting tube 264. A connecting shell 266 is fixedly connected to the other end of the connecting tube 264. The connecting shell 266 is fixedly connected to the lower part of the lower chamber 24. A sliding shell 267 is slidably connected to the upper part of the connecting shell 266. Two springs 268 are fixedly connected between the sliding shell 267 and the connecting shell 266. Damping fluid is injected between the connecting shell 266 and the sliding shell 267.

[0037] The vertical rod mechanism 3 includes a vertical rod 31 fixedly connected to the upper end of the connecting seat 221. The vertical rod 31 has multiple regular hexagonal slots 311 on the side facing the generator set 1. The regular hexagonal slots 311 are filled with sound-absorbing cotton. Multiple liquid injection nozzles 312 are fixedly provided on the side of the vertical rod 31 away from the generator set 1.

[0038] The vertical rod 31 has multiple liquid storage chambers 313 inside, and each of the liquid injection nozzles 312 corresponds to a liquid storage chamber 313. Multiple baffles 314 are provided inside the liquid storage chamber 313, and the cross-sectional shape of each baffle 314 is different.

[0039] The working principle of this invention is as follows: When the generator set 1 is running, it generates vibration. The vibration is transmitted to the sliding plate 222 through the connecting seat 221, causing it to move up and down in the upper chamber 213. When the sliding plate 222 is pressed down, it is driven by the connecting block 235 and the rotating rod 234. The sliding rod 233 slides inward into the sliding groove 232. The rubber pad in the sliding groove 232 consumes part of the vibration energy through friction damping, achieving initial buffering. The sliding rod 233 squeezes the internal space of the fixed plate 231, making the internal pressure of the fixed plate 231 increase. The air in the fixed plate 231 is discharged into the through hole 214 through the exhaust hole 216, and then enters the connecting ring 251, pushing the sliding plate 252 downward to squeeze the coarse spring 254. The coarse spring 254 further absorbs the vibration energy.

[0040] When the sliding plate 252 moves down, it drives the limiting plate 253. The connecting short plates 261 on both sides press down the airbag 263 simultaneously. After being compressed, the airbag 263 enters the connecting pipe 264 through air pressure. The air pressure pushes the slide rod 265 in the connecting pipe 264 to move towards the connecting shell 266. The slide rod 265 squeezes the damping fluid in the connecting shell 266. The damping fluid in the connecting shell 266 is squeezed, and the damping fluid pushes the sliding shell 267 to rise. The sliding shell 267 pulls the spring 268 to undergo elastic deformation, further consuming energy.

[0041] The sound-absorbing cotton in the hexagonal groove 311 of the vertical rod 31 absorbs sound waves, and the injection nozzle 312 can inject damping fluid into the storage cavity 313. The sound energy is consumed by the flow of damping fluid and the disturbance of the baffle 314, reducing the operating noise. The irregular cross section of the baffle 314 changes the flow path of the damping fluid in the storage cavity 313, generating turbulence to enhance energy absorption.

[0042] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
