Description

Technical Field

[0001] This utility model relates to the field of chassis and fuel tank technology, specifically to a common chassis for generator sets with fuel tanks. Background Technology

[0002] In the overall structural design of generator sets, the generator set requires a dry-sump oil tank attached to a common base frame. This necessitates transferring the circulating lubricating oil from the diesel generator's oil sump to the tank on the common base frame. The common base frame is the core load-bearing component, requiring the fixing of the diesel generator, generator, fuel tank, and related auxiliary devices. Existing generator set common base frames generally employ an independent fuel tank and a dedicated lubricating oil pump. This means that lubricating oil is stored in a separate tank, and a dedicated lubricating oil pump is additionally configured to draw lubricating oil from the diesel generator's oil sump to the fuel tank, achieving oil recycling and replenishment.

[0003] However, the dedicated lubricating oil pump increases the manufacturing cost of the generator set, requiring the design of corresponding mounting brackets, connecting pipelines and control circuits. The common base frame also needs to reserve sufficient vertical installation space, resulting in an increase in the overall height of the base frame. Consequently, during the operation of the diesel generator, the vibration load will be amplified due to the higher center of gravity, which will change the center of gravity distribution of the generator set and reduce the stability of its overall structure.

[0004] Therefore, this utility model proposes a common base frame for generator sets with oil tanks to solve the above-mentioned problems. Utility Model Content

[0008] Furthermore, the base frame body is provided with lifting holes and forklift slots. The lifting holes are symmetrically arranged on both sides of the base frame body, and the forklift slots are arranged through the base frame body.

[0009] Furthermore, the base frame body is also connected to multiple reinforcing beams, which are connected to the bottom of the mounting plate, and multiple auxiliary support ribs are provided below the reinforcing beams.

[0020] Furthermore, a baffle 10 is connected inside the lubricating oil tank 4, and the interior of the lubricating oil tank 4 is divided into a sedimentation zone and an oil outlet zone by the baffle 10. A gap is provided between the upper end of the baffle 10 and the inner wall of the top of the lubricating oil tank 4. The bottom surface of the sedimentation zone inside the lubricating oil tank 4 is inclined, and multiple guide ribs 11 are provided on the bottom surface of the sedimentation zone. A filter screen 12 is installed inside the lubricating oil tank 4 near the oil outlet 7, and the filter screen 12 is slidably connected to the inner wall of the lubricating oil tank 4.

[0021] Furthermore, the top of the lubricating oil tank 4 is provided with an inspection port 13, and a sealing end cap 14 is connected to the inspection port 13. The sealing end cap 14 is bolted to the edge of the inspection port 13, and a rubber sealing ring 15 is provided between the sealing end cap 14 and the inspection port 13. A venting device is detachably connected to the sealing end cap 14. The venting device includes a housing 16, with an air inlet pipe 17 connected to the bottom of the housing 16 and an air outlet pipe 18 connected to the top of the housing 16. The air inlet pipe 17 and the air outlet pipe 18 are arranged alternately. A desiccant 19 is provided inside the housing 16, and the housing 16 is threadedly connected to the sealing end cap 14.

[0022] Furthermore, elastic supports are provided at the four corners of the bottom of the base frame body 1. Each elastic support includes an upper connecting plate 20, a lower support seat 21, and a rubber damping block 22. The upper connecting plate 20 is welded and fixed to the base frame body 1, and the rubber damping block 22 is connected between the upper connecting plate 20 and the lower support seat 21. The base frame body 1 is provided with lifting holes 23 and forklift slots 24. The lifting holes 23 are symmetrically arranged on both sides of the base frame body 1, and the forklift slots 24 are arranged through the base frame body 1. Multiple reinforcing beams 25 are also connected to the base frame body 1. The reinforcing beams 25 are connected to the lower part of the mounting plate 2, and multiple auxiliary support ribs 26 are provided below the reinforcing beams 25.

[0023] The working process of this utility model is as follows: During diesel generator operation, lubricating oil used in the lubrication system collects in a dry oil sump 3 mounted on a common base frame. The dry oil sump 3 is positioned higher than the lubricating oil tank 4 below. Under its own gravity, the lubricating oil automatically flows into the inlet 6 of the lubricating oil tank 4 through the connecting pipe 5. Before flowing into the connecting pipe 5, the lubricating oil passes through a connecting component 8. The magnetic block 9 within the connecting component 8 strongly adsorbs ferromagnetic metal shavings mixed in with the lubricating oil, completing the first purification of the lubricating oil. The lubricating oil then enters the sedimentation zone of the lubricating oil tank 4 through the inlet 6. A baffle 10 within the lubricating oil tank 4 divides the internal space into a sedimentation zone and an outlet zone. The lubricating oil flows through the gaps above the baffle 10, slowing the flow rate and facilitating the settling of impurities within the lubricating oil tank 4. The inclined bottom surface of the sedimentation zone and the guide ribs 11 above it guide the settled impurities to slide to the lowest point of the tank bottom for easy collection and cleaning. Finally, the lubricating oil, after initial sedimentation, slowly flows into the outlet zone through the gaps above the baffle 10. The lubricating oil then passes through the filter screen 12 installed near the oil outlet 7. The filter screen can intercept finer impurities. The filter screen 12 adopts a sliding connection, which makes it easy to remove it from the inspection port 13 for cleaning or replacement. When it is necessary to clean the impurities at the bottom of the oil tank or replace the filter screen 12, the sealing end cover 14, which is fixed to the inspection port 13 by bolts, can be opened for replacement.

[0024] Meanwhile, as the oil level and temperature change, the internal pressure of the lubricating oil tank 4 will change. The venting device maintains the internal and external pressure balance through the air inlet pipe 17 and the air outlet pipe 18. The desiccant 19 in the venting device can absorb the moisture in the incoming air and prevent water vapor from condensing and contaminating the lubricating oil. The venting device is threadedly connected to the sealing end cap 14, which facilitates the replacement of the desiccant 19.

[0025] During operation, the weight and operational vibration of the diesel generator and the entire lubrication system are borne by the common base frame. The elastic supports at the bottom of the base frame 1 effectively absorb and isolate vibrations, improving the smoothness and stability of generator operation. The lifting holes 23 and forklift slots 24 on the base frame 1 facilitate the handling and positioning of the entire generator set.
