Abstract
Description
Technical Field
[0001] The utility model relates to an oil tank for a generator set, in particular to a special-shaped oil tank. Background Art
[0002] The fuel tank of a generator set is a device for storing fuel for the unit. Common fuel tanks have a flat bottom structure, such as Figure 1 and Figure 2 As shown, the refueling port, the oil inlet 10, the oil return port 20 and the electronic liquid level gauge 30 are all integrated on the fuel tank cover 40. The oil inlet 10 is connected to the oil suction pipe to suck oil to supply the generator set, and the excess fuel returns to the fuel tank from the oil return port 20. Since the distance between the refueling port 10 and the oil inlet 20 is too close, the oil residue in the return oil may be sucked away again by the oil suction pipe. In addition, the return oil temperature is high and will be re-extracted before it has time to dissipate the heat, which is not conducive to the heat dissipation of the engine. In addition, when the fuel tank is not used for a long time or is cleaned regularly, it is necessary to drain the fuel tank through the oil drain port, and the flat bottom structure will cause the fuel to be discharged uncleanly. Utility Model Content
[0003] In order to solve the problems in the prior art, the utility model provides a special-shaped oil tank.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A special-shaped oil tank comprises a tank body, wherein a refueling cover plate, an oil inlet cover plate and an oil return cover plate are arranged on the upper part of the tank body, and the oil inlet cover plate and the oil return cover plate are arranged at a distance; a refueling port is arranged on the refueling cover plate, an oil inlet port is arranged on the oil inlet cover plate, an oil suction pipe extending into the oil tank is connected to the oil inlet port, and an oil return port is arranged on the oil return cover plate;
[0006] The bottom surface of the box body is an inclined structure.
[0007] Preferably, the bottom surface of the box body is in the shape of a single slope, and the oil drain port is close to the lower bottom surface.
[0008] Preferably, when the fuel tank is a narrow structure, the fuel filling cover plate, the oil inlet cover plate and the oil return cover plate are all located on the same straight line.
[0009] Preferably, when the oil tank is preferably a wide structure, the oil inlet cover plate is arranged on the side with a higher bottom surface, and the oil return cover plate is arranged on the side with a lower bottom surface.
[0010] Preferably, the bottom surface of the box body is in the shape of a double inclined plane that is bilaterally symmetrical, the intersection of the two inclined planes is the low position of the box body, and the oil drain port is arranged between the two inclined planes.
[0011] Preferably, an L-shaped connection seat is provided on the outer side of the box body, and a through hole connected to the unit base frame is provided on the connection seat.
[0012] Preferably, the oil inlet cover plate is provided with a fuel heater pipe seat; the oil filling cover plate is provided with a mechanical liquid level gauge, and the oil inlet cover plate and the oil return cover plate are installed with electronic liquid level gauges.
[0013] Preferably, a plurality of partitions are arranged at intervals in the oil tank along the front-to-back direction, and holes are arranged on the partitions, wherein one or more partitions are located between the oil suction port and the oil return port.
[0014] Preferably, the partitions are staggered in the box body so that the return oil forms an S-shaped route.
[0015] Preferably, the unit is provided with one or more groups, and the number of oil inlets and oil return ports on the oil inlet cover plate and the oil return cover plate is consistent with the number of units.
[0016] Beneficial effects of the utility model:
[0017] 1. In the utility model, the oil inlet and return oil are arranged separately, which is more conducive to the heat dissipation of the return oil compared to the form in which the oil inlet and return oil are integrated on a cover plate, and is also more suitable for the use scenario where multiple units share a common oil tank.
[0018] 2. In the utility model, the bottom surface of the box body is a single slope or a symmetrical double slope. When the bottom surface of the box body is a single slope, the oil drain port of the box is close to the lower bottom surface. When the bottom surface of the box body is a double slope, the intersection of the two slopes is low, and the intersection of the slope and the box body is high. The oil drain port is arranged between the two slopes. The positions of the oil drain ports of both types are located at the lowest position of the oil tank. Under the action of the slope, the oil gathers to the lowest point of the oil tank and flows out from the oil drain port, which effectively ensures that the oil can be emptied when draining the oil, facilitates the outflow of oil residue, and facilitates internal cleaning.
[0019] 3. In the utility model, a partition is provided in the oil tank, which separates the oil inlet from the oil return port. A plurality of holes are opened on the partition. The partition will block the oil residue and iron chips from moving to the oil inlet, while not hindering the oil from flowing from the holes to the oil inlet, effectively blocking the oil residue and iron chips from flowing to the oil inlet, thereby ensuring the fuel quality at the oil inlet; the partition is connected to the oil tank wall, and the heat of the return oil is not only directly dissipated through the oil tank wall, but also conducted to the oil tank wall through the partition, thereby accelerating the heat dissipation of the return oil.
[0020] When the box body is limited by the unit space and cannot ensure that the oil inlet cover and the oil return cover are set far apart, multiple partitions are staggered in the box body, so that the return oil can flow to the oil inlet only after passing through an S-shaped route, extending the route and time of the return oil flow, that is, extending the time available for the return oil to dissipate heat.

[0038] Embodiment 1:
[0039] like Figures 3 to 9As shown, this embodiment provides a special-shaped oil tank, including a box body 1, the box body 1 is a long structure, with its front-to-back direction as the long direction, and a refueling cover plate 2, an oil inlet cover plate 3 and an oil return cover plate 4 are arranged in sequence at intervals on the upper part of the box body from front to back, and the oil inlet cover plate 3 and the oil return cover plate 4 are arranged far apart.
[0040] The fuel filling cover plate 2 is provided with a fuel filling port 21 and a vent 22 .
[0041] The oil inlet cover plate 3 is provided with an oil inlet port 31, and the oil inlet port 31 is connected to an oil suction pipe 34 extending into the oil tank, and the oil suction pipe 34 extends to the bottom of the oil tank. The oil inlet cover plate 3 is also provided with a fuel heater pipe seat 32. When the unit is started at low temperature, a fuel heater is required to assist in starting the engine. The fuel heater requires fuel as energy, so a pipe seat dedicated to the fuel heater is provided in the oil tank to provide energy for the fuel heater.
[0042] The oil return cover plate 4 is provided with an oil return port 41 .
[0043] The utility model adopts the separate arrangement of the oil inlet and the oil return, which is more conducive to the heat dissipation of the return oil compared with the form in which the oil inlet and the return oil are integrated on a cover plate.
[0044] A mechanical level gauge 23 is provided on the refueling cover plate 2, an electronic level gauge 33 is installed on the oil inlet cover plate 3, and an electronic level gauge 42 is installed on the oil return cover plate 4. The mechanical level gauge and the electronic level gauge monitor simultaneously to play a complementary backup role.
[0045] The bottom surface 11 of the box body is in a single inclined plane shape, and the oil drain port 5 is close to the lower bottom surface. Like this, the oil drain port 5 is located at the lowest position of the oil tank, and the oil is gathered to the lowest point of the oil tank under the effect of the inclined plane and flows out from the oil drain port.
[0046] Specifically, during processing, the bottom surface 11 of the box body is composed of a fixed and spliced straight plate and an inclined plate, the inclined angle of the inclined plate is 3-5 degrees, the straight plate is located at the lower end, and the straight plate is set horizontally. The inclined plate part effectively ensures that the oil flows to the lower part, and gravity is applied to the straight plate part, which ensures that the oil tank will not slide down and squeeze the side wall of the unit chassis.
[0047] The housing 1 of this embodiment is limited by the space of the unit, and the housing 1 is selected to be a narrow structure, and the oil filling cover plate 2, the oil inlet cover plate 3 and the oil return cover plate 4 are all located on the same straight line.
[0048] A plurality of partitions 6 are arranged in the oil tank 1 along the front-to-back direction, wherein one or more partitions are located between the oil suction port and the oil return port. The partition 6 separates the oil inlet from the oil return port. Holes 61 are arranged on the partition 6. The partition will block the oil residue and iron filings from moving toward the oil inlet while not hindering the oil from flowing from the holes to the oil inlet.
[0049] At the same time, the partition 6 is connected to the wall of the oil tank 1. In addition to being directly dissipated through the oil tank wall, the heat of the return oil is also conducted to the oil tank wall through the partition, thereby accelerating the heat dissipation of the return oil.
[0050] An L-shaped connection seat 12 is arranged outside the box body 1, and a through hole for connecting with the unit bottom frame is formed on the connection seat 12.
[0051] Embodiment 2:
[0052] like Fig.10 As shown, the difference between this embodiment and the first embodiment is that the bottom surface 11 of the box body is a double inclined surface that is bilaterally symmetrical.
[0053] When the bottom surface 11 of the box body is a double slope, the intersection of the two slopes is low and the intersection of the slope and the box body is high. The oil drain port is set between the two slopes. Such an oil drain port is located at the lowest position of the oil tank. Under the action of the slope, the oil gathers to the lowest point of the oil tank and flows out from the oil drain port.
[0054] Embodiment three:
[0055] like Figures 11 to 13 As shown, the difference between this embodiment and the first embodiment is that: when the unit has enough space to place the oil tank, the oil tank 1 is selected as a wide structure. At this time, it is preferred to set the oil inlet cover plate 3 on the side with a higher bottom surface, and the oil return cover plate 4 on the side with a lower bottom surface, so that the oil residue is settled at the lower end of the bottom surface, protecting one side of the oil suction pipe to have good fuel quality.
[0056] Embodiment 4:
[0057] like Fig.14 As shown, the difference between this embodiment and the first embodiment is that: when the box body 1 is limited by the unit space and cannot ensure that the oil inlet cover plate 3 and the oil return cover plate 4 are set far apart, a plurality of partitions 6 are staggered in the box body, so that the return oil can flow to the oil inlet only after passing through an S-shaped route, thereby extending the route and time of the return oil flow, that is, extending the time available for the return oil to dissipate heat.
[0058] Embodiment five:
[0059] like Fig.15 As shown, this embodiment discloses a dual-unit shared oil tank state, where two units 71 and 72 share one oil tank.
[0060] For dual or multiple units, the number of oil inlets and oil return ports should be consistent with the number of units.
