[0051] As shown in Figures 1-8, the present application provides a vertical generator set, including an engine, a generator 100, a first cooling mechanism, a second cooling mechanism and a third cooling mechanism.

[0052] The engine is a bedroom engine, which includes an engine body, a crank-connecting rod mechanism, a valve mechanism, a fuel supply mechanism, etc. These are all existing technologies and will not be described in detail here. The engine body includes a box body 210 and an oil pan 220.

[0053] The housing 210 has a first mounting cavity in which a cylinder and a crank-connecting rod mechanism are disposed. An oil pan 220 is disposed below the housing 210 and is used to store engine oil.

[0054] The housing 210 has a second mounting cavity, located above or below the first mounting cavity. In this embodiment, the second mounting cavity is located above the first mounting cavity. The generator 100 is mounted within the second mounting cavity and is transmission-connected to the engine's power output. By placing the generator 100 within the engine's housing, the generator's protection is enhanced.

[0055] The first cooling mechanism is used to cool the generator 100 using the oil stored in the oil pan 220. When in use, the first cooling mechanism cools the generator 100 using the oil in the oil pan 220, thereby improving the cooling effect on the generator 100.

[0056] In one embodiment, the first cooling mechanism includes an oil spray device 310 , an oil pump 320 , and an oil return structure.

[0057] An oil sprayer 310 is installed in the second mounting cavity and is used to spray oil into the generator 100. The oil pump 320 has its oil inlet connected to the oil pan 220 and its oil outlet connected to the oil sprayer 310. The oil return structure has its oil inlet connected to the second mounting cavity and its oil outlet connected to the oil pan 220. This structure is used to return the oil in the second mounting cavity to the oil pan 220.

[0058] When in use, the oil pump 320 pumps the oil in the oil pan 220 to the oil spraying device 310 , and the oil spraying device 310 sprays the oil to the generator 100 , thereby achieving the purpose of cooling the generator 100 .

[0059] The first cooling mechanism of this structure has a simple structure and a reasonable design.

[0060] In one embodiment, a first oil passage 211 is defined on the sidewall of the housing 210. The oil inlet of the first oil passage 211 communicates with the oil outlet of an oil pump 320, which in turn communicates with the oil inlet of the oil injection device 310. Specifically, the oil inlet of the first oil passage 211 communicates with the oil outlet of the oil pump 320 via an oil pipe (not shown). During operation, the oil pump 320 sprays the oil in the oil pan 220 from the oil injection device 310 toward the generator 100, thereby cooling the generator 100.

[0061] This structure achieves the purpose of making the structure of the first cooling mechanism simpler and more compact by providing the first oil channel 211 on the side wall of the box body 210 .

[0062] In one embodiment, the oil outlet end of the first oil passage 211 includes a first oil outlet hole 212 and a second oil outlet hole 213 .

[0063] An annular oil guide groove 214 is provided on the inner side of the housing 210. The oil guide groove 214 communicates with the first oil outlet hole 212. The oil sprayer 310 is adapted to the oil guide groove 214 and is detachably connected and sealed to the oil guide groove 214. The first side arm of the second mounting cavity is provided with a first axial hole, and the second oil outlet hole 213 communicates with the first axial hole.

[0064] During use, the engine oil enters the oil guide groove 214 from the first oil outlet hole 212 and is then sprayed out from the oil spray device 310. At the same time, the engine oil enters the first shaft hole from the second oil outlet hole 213, thereby achieving the purpose of lubricating the transmission shaft (for example, the crankshaft, the generator 100 shaft, etc.).

[0065] In one embodiment, the housing 210 is further provided with a second oil passage 215. A second axial hole is provided on the second sidewall of the first mounting cavity (i.e., the sidewall opposite the first sidewall). The oil inlet of the second oil passage 215 is connected to the oil outlet of the oil pump 320, and the oil outlet is connected to the second axial hole. The provision of the second oil passage 215 allows lubrication of the connection between the second sidewall and the drive shaft.

[0066] In one embodiment, the housing 210 is further provided with a third oil passage 216, a first end of which is in communication with the first oil passage 211, and a second end of which is in communication with the second oil passage 215. The provision of the third oil passage 216 connects the first oil passage 211 and the second oil passage 215, thereby facilitating the flow of engine oil into the first oil passage 211 or the second oil passage 215 even if the oil inlet of the first oil passage 211 or the oil inlet of the second oil passage 215 is blocked.

[0067] Because the second mounting cavity is located above the oil pan 220, in one embodiment, the oil return structure includes an oil return passage 330. A first end of the oil return passage 330 communicates with the bottom of the second mounting cavity, and a second end communicates with the oil pan 220. During operation, the oil in the second mounting cavity flows back into the oil pan 220 through the oil return passage 330 under the action of gravity.

[0068] The second cooling mechanism is used to cool the engine. When in use, the second cooling mechanism takes away the heat generated when the engine is working, thereby cooling the engine body and the engine oil in the oil pan 220, thereby achieving the purpose of ensuring the temperature of the engine oil.

[0069] Preferably, the oil pan 220 is provided at the air outlet of the second cooling mechanism.

[0070] In one embodiment, the second cooling mechanism includes an air guide cover 410 , an impeller 420 and an outer cover 430 .

[0071] An air scoop 410 is disposed at the first end of the housing. It has an air inlet, and the scoop 410 and the housing enclose a first air duct 440. An impeller 420 is disposed inside the scoop 410. An outer cover 430 is hollow and open at both ends. It fits over the housing. The first end of the outer cover 430 is fixedly connected to the air scoop 410, and the second end has an air outlet. The outer cover 430 and the housing enclose a second air duct 450. The air inlet of the second air duct 450 communicates with the air outlet of the first air duct 440.

[0072] Preferably, the inner side of the air scoop 410 has a plurality of air guide grooves 411, which are arranged around the axis of the air scoop 410. When in use, the air guide grooves 411 divert the cooling air entering the air scoop 410, and allow the diverted cooling air to reach a designated area and remove heat from the engine body in the designated area. At the same time, more cooling air is sent to the area with a higher temperature of the engine body, while less cooling air is sent to the area with a lower temperature of the engine body, thereby achieving the purpose of improving the cooling effect on the engine.

[0073] Preferably, the air guide groove 411 is spiral-shaped. By providing the spiral-shaped air guide groove 411, the wind entering the air guide cover 410 can be better accelerated, thereby achieving the purpose of improving the cooling effect.

[0074] Preferably, the air inlet end of the second air duct 450 is in an open trumpet shape. When air enters the second air duct 450 from the first air duct 440, the air inlet end of the second air duct 450 is in an open trumpet shape, thereby accelerating the air entering the second air duct 450, thereby improving the cooling effect on the engine.

[0075] Preferably, a plurality of first heat sinks 217 are provided on the outer side of the box body 210 . By providing the first heat sinks 217 on the outer side of the box body 210 , the heat dissipation effect of the box body 210 is improved.

[0076] Preferably, the first heat sink 217 is annular and is located on a side of the box body 210 where the cylinder is provided.

[0077] Preferably, a plurality of first heat sinks 217 are sequentially spaced apart on the outside of the box body 210 along the axis of the cylinder.

[0078] Preferably, a plurality of second cooling fins 221 are provided on the outside of the oil pan 220. Preferably, the second cooling fins 221 are L-shaped, with a first end extending axially along the oil pan 220 and a second end extending radially toward the axis of the oil pan 220. The air is divided and redistributed by the second cooling fins 221 and directed toward the bottom of the oil pan 220, removing heat from the oil pan 220 before being released through designated air outlets. This forms a complete air duct, removing heat from the engine.

[0079] In one embodiment, the third cooling mechanism includes a radiator 510, which is positioned at the air inlet of the second cooling mechanism. The oil inlet of the radiator 510 is connected to the oil outlet of the oil pump 320, and the oil outlet is connected to the oil sump 220. During operation, cooling air enters the cooling air duct, dissipating heat from the radiator 510 and thereby cooling the engine oil.

However, it is understood that the embodiments of the present application can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
