Description

Technical Field

[0001] The present invention relates to the technical field of piston internal combustion engines, in particular to an integrated diesel generator set. Background Art

[0002] A diesel generator set is a small power generation device that uses an internal combustion engine powered by diesel to drive an AC generator. It consists of core components such as the diesel engine, generator, control box, and fuel tank, and is suitable for emergency power supply or mobile scenarios. During operation, a piston internal combustion engine reciprocates in a cylinder. Two air rings and an oil ring are mounted on the piston. As the piston gradually descends, the oil ring scrapes the oil from the inner wall of the cylinder below. As the two air rings descend synchronously, they slide against the oil film on the inner wall of the cylinder. The presence of the oil film ensures smooth piston movement and a tight seal in the air chamber above the piston.

[0003] The air ring in the prior art is a C-shape with a notch. Although the influence of the air ring notch on the sealing is avoided by symmetrically arranging the two air rings, the problem of the oil film at the notch notch notching always exists. That is, when the two air rings move synchronously, the oil film on the local cylinder inner wall is normally scraped twice, while the path oil film at the notch of one air ring is only scraped once, and this scraped oil film comes from the non-notch part of the other air ring. To further understand, the cylinder inner wall uniform ring is set as multiple vertical sections. The vertical section through which the air ring notch passes is always scraped once, and the other vertical sections are always scraped twice. In this way, the oil film thickness left on the cylinder inner wall is uneven.

[0004] Uneven cylinder oil film thickness can cause many problems. One is that the oil film thickness at the section at the ring gap is specified as normal, so other sections are scraped twice, and the oil films in other sections become thinner. When the ring at the corresponding position slides in the cylinder, the friction between the ring and the cylinder increases, and the ring wears faster. At the same time, the temperature of the cylinder wall will rise higher. If the oil film thickness on the inner wall of the cylinder that has been scraped twice is specified as normal, then the section at the ring gap is only scraped once, and the oil film left at the section at the ring gap is relatively thicker. The excess oil film is burned in the air chamber above the piston, resulting in oil burning.

[0005] If the two air rings can rotate on the piston, the problem of the oil film in some local sections on the inner wall of the cylinder being always thicker or thinner than other sections can be avoided. The thickness of the oil film left after being scraped by the two air rings is almost the same, thereby making the oil film distribution on various parts of the inner wall of the cylinder more even. For this purpose, the present invention provides an integrated diesel generator set. Summary of the Invention

[0058] The spring part 18 is mounted on the joint control shaft 17, and the shaft wheel set 16 is driven on one side of the spring part 18;

[0059] The oil delivery part 14 is driven by one side of the shaft-wheel group 16, and the scattering ring group 20 is driven by the other side of the shaft-wheel group 16. The oil delivery part 14 is connected between the annular oil storage tank 10 and the scattering ring group 20. The oil sprayed from the scattering ring group 20 surrounds and sprinkles onto the inner wall of the cylinder 3.

[0060] refer to Figure 8It is understood that the scattering ring group 20 includes a ring cover 24 connected to the oil delivery part 14, a ring concave shell 23 that cooperates with the ring cover 24 to form a ring box, a plurality of unit tubes 25 connected to the outside of the ring concave shell 23, and an inner ring gear 22 fixed inside the ring concave shell 23.

The neck shaft 34 is movably sleeved in the shaft hole opened on the inner frame 15. One overlapping gear 35 is engaged with the inner ring gear 22 for transmission, and the other overlapping gear 35 is driven by the spring part 18.

[0062] refer to Figure 9 It is understood that the spring part 18 includes a spring 31 fixed on the joint control shaft 17, an outer ring gear 30 fixed on the outside of the spring 31, a back plate 32 fixed on the bottom surface of one side of the outer ring gear 30, and a J-shaped spring clip 33 intercepting the back plate 32.

[0064] The oil delivery portion 14 includes an oil delivery box 36 having one end fixedly connected to the annular oil storage tank 10, an impeller 37 disposed in the oil delivery box 36, and an impeller shaft 38 fixed at the axis of the impeller 37. One end of the impeller shaft 38 extends to the outside of the oil delivery box 36, and the end of the impeller shaft 38 is meshed with the lap gear 35 through a fixed gear. The other end of the oil delivery box 36 passes through the ring cover 24 and extends to the inside of the annular concave shell 23. Figure 10It is understood that the impeller shaft 38 drives the impeller 37 to rotate, causing the fluid in the oil box 36 to be directionally transported. The impeller 37 is located in a circular box set in the middle of the fork frame 26. The oil in the annular oil storage tank 10 is sucked into the oil box 36, and then the oil is injected into the ring box composed of the ring cover 24 and the ring concave shell 23, and then diffused and discharged through multiple unit tubes 25. During the process, the inner ring gear 22 rotates to drive the ring concave shell 23, and then the multiple unit tubes 25 move synchronously. The oil sprayed from the unit tube 25 circularly impacts the inner wall of the cylinder 3, so that the amount of oil attached to the inner wall of the cylinder 3 in all directions is the same. After being scraped by the oil ring 9, the oil on the inner wall of the cylinder 3 is burned and heated, and the oil film thickness generated at various places on the inner wall of the cylinder 3 is the same.

[0065] The adjuster 13 includes a control tube 41 arranged in a ring inside the barrel-shaped piston 7, a shift ring 40 fixedly mounted on both ends of the outer wall of the control tube 41, a limit ring 42 fixedly mounted in the middle of the outer wall of the control tube 41, a plurality of T-seats 43 evenly arranged on the outside of the limit ring 42, and a plurality of adjustment groups 39 evenly arranged on the outside of the shift ring 40.

[0066] The shift ring 40 includes a ring body and multiple arc-shaped protrusions evenly arranged on the outside of the ring body. The end of the joint control shaft 17 is engaged with the internal gear ring fixed inside the centralized control tube 41 through a fixed shaft gear. The T seat 43 is fixed on the barrel-shaped piston 7, and the limit ring 42 is stuck in the arc-shaped slide groove opened on the T seat 43.

[0067] The direction adjustment group 39 includes a T-shaped column 48 with one end in contact with the shift ring 40, a unit rack 46 fixed to the other end of the T-shaped column 48, an arc spring piece 47 fixed to one side of the T-shaped column 48, a second one-way bearing 45 provided on one side of the unit rack 46, and a lead-out shaft 44 fixed in the middle of the second one-way bearing 45. The outside of the second one-way bearing 45 is engaged with the unit rack 46 through a fixed sleeve cylindrical gear, and one end of the lead-out shaft 44 is engaged with the convex teeth arranged on the inner side of the C-shaped gas ring 8 through a fixed gear. Space is opened in the housing of the barrel piston 7 for the lead-out shaft 44, the second one-way bearing 45, the unit rack 46 and the T-shaped column 48 to move. Figure 14 It is understood that the second one-way bearing 45 is movably sleeved in the axial hole opened on the barrel piston 7 housing, the second one-way bearing 45 and the unit rack 46 are arranged in a plate cavity opened in the barrel piston 7 housing, and space is reserved in the plate cavity for the unit rack 46 to move, and the T-shaped column 48 slides through the square hole opened on the barrel piston 7 housing, and the arc spring piece 47 is cushioned between the inner wall of the barrel piston 7 and the T-shaped column 48, so that the T-shaped column 48 and the shift ring 40 are always in contact.

[0068] When the internal combustion engine is running, the internal barrel piston 7 rises and falls continuously, and inertia causes the weight 19 to move back and forth relative to the barrel piston 7. The weight 19 drives the fork frame 26. The reciprocating movement of the fork frame 26 causes the first one-way bearing 28 to rotate intermittently in a directional manner, and then drives the joint control shaft 17 to rotate through the worm 29. On the one hand, the joint control shaft 17 transmits the centralized control cylinder 41, and the centralized control cylinder 41 drives the two dial rings 40 to rotate. When the arc-surface protrusion on the dial ring 40 encounters the T-shaped column 48, it will push the T-shaped column 48, and then the T-shaped column 48 slides back and forth to drive the unit rack 46. Next, the second one-way bearing 45 rotates intermittently in a directional manner to drive the lead-out shaft 44, and then the transmission causes the C-shaped gas ring 8 to rotate, so that the two C-shaped gas rings 8 on the barrel piston 7 rotate synchronously.

[0069] On the other hand, the rotation of the linkage shaft 17 causes the mainspring 31 to contract and store force. When the stored force pressure is sufficient, it will break through the position of the J-shaped spring 33 on the back plate 32. After breaking through, the mainspring 31 releases power, and the outer ring gear 30 completes one circle of rotation. During this process, the outer ring gear 30 drives the shaft wheel group 16, and the shaft wheel group 16 simultaneously drives the inner ring gear 22 and the impeller shaft 38. As mentioned earlier, the rotation of the impeller 37 causes the engine oil to be transported in the oil box 36. The engine oil in the oil box 36 is supplied to the ring box and then sprayed out through the unit pipe 25.

[0070] Since the outer ring gear 30 rotates intermittently, the circular spraying method of the engine oil has an interruption period. During the interruption period, the engine oil is gradually stored in the annular oil storage tank 10 and the engine oil is collected through multiple long oil pipes 11. The engine oil in the annular oil storage tank 10 will automatically lose due to gravity, but the loss rate is lower than the rate of supplying the engine oil. In this way, the annular oil storage tank 10 is gradually filled with engine oil to supply the next circular spraying of engine oil.

[0071] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
