This embodiment provides an automobile alternating current generator with amortization ring structure, and during operation, generator 7 begins to rotate, and radiator fan 12 synchronous revolution is to the inside air-cooled cooling of generator 7, and the motor shaft of generator 7 drives disc 13 and rotates, and disc 13 drives piston rod 16 reciprocating motion, and piston 18 reciprocating motion in cylinder 17 compresses the air in the cylinder 17, then makes it pass through intake pipe 3 transmission and get into in seal box 2.
Gas enters one of the chambers. When the second chamber 26 is located at the air inlet pipe 3 and the air inlet opening as shown in fig. 5, the air is transmitted into the second chamber 26, and since the air inlet opening is directed to the lower right, the air entering the second chamber 26 gives an impact force to the rotating plate 20 on the right side of the second chamber 26, and the air pressure in the second chamber 26 increases, pressing the rotating plate 20 on the right side of the second chamber 26 to rotate clockwise, thereby rotating all the rotating plates 20.
As shown in fig. 6, the initial position of the cooling water in the water storage tank 24 is flush with the uppermost surface of the cooling water tank 1, and the rotary plate 20 rotates to stir the cooling water to rotate clockwise. When the rotating plate 20 is located between the water storage tanks 24, a part of the cooling water (located in the fourth cavity 28 on the right side of the lowermost rotating plate 20) flows back into the water storage tanks 24, and the other part of the cooling water (located in the fifth cavity 29 on the left side of the lowermost rotating plate 20) rotates by the rotating plate 20.
Referring to fig. 5 again, when the rotating plate 20 at the right side of the fifth chamber 29 contacts the inner wall of the seal box 2, the cooling water (in the fifth chamber 29) cannot flow back, the rotating plate 20 continues to drive the cooling water to rotate, when reaching the liquid outlet of the circulating pipe 4, the cooling water flows out from the liquid outlet of the circulating pipe 4 through centrifugal force, and part of the liquid continues to rotate along with the rotating plate 20 until the liquid enters the water storage tank 24 when rotating to the position of the water storage tank 24 again. The cooling water flowing out from the circulation pipe 4 cools the outside of the generator 7 and then flows into the water storage tank 24 through the third check valve 23, the cooling water circulates in and out through the circulation pipe 4, and the third check valve 23 prevents the cooling water from flowing out from the water storage tank 24.
As shown in fig. 7, when the rotating plate 20 is about to rotate for one revolution, the chamber of the second chamber 26 rotates to the position of the relief valve 9, the air pressure in the second chamber 26 exceeds the threshold set by the relief valve 9, the relief valve 9 relieves the pressure, and the rotating plate 20 continues to rotate. The second chamber 26 reaches the position of the first one-way valve 10, cooling water can be added into the water storage tank 24 as required, the cooling water is sucked into the second chamber 26 through the first one-way valve 10 due to the fact that the pressure relief air pressure in the second chamber 26 is small, and the arc-shaped baffle plate 22 prevents liquid flowing in from the first one-way valve 10 from being sucked out when the pressure relief valve 9 relieves the pressure. At this time, the third chamber 27 rotates to the air outlet position of the air inlet pipe 3, and the third chamber 27 starts to supply air to continue rotating the rotating plate 20.
The generator 7 is operated all the time, causing the rotating plate 20 to rotate all the time. When the generator 7 rotates slowly, the reciprocating speed of the piston 18 is slow, the compressed gas speed is slow, the rotating plate 20 rotates slowly, and only air cooling and external cooling are needed for cooling the generator 7.
When the rotating speed of the generator 7 is accelerated, the rotating speed of the rotating plate 20 is also accelerated, and after the rotating plate reaches a certain speed, by taking a picture 5 as an example, the rotating plate 20 stirs part of cooling water to move towards the direction of the liquid inlet pipe 5, and the liquid is subjected to the pressure of air pressure, the rotating plate 20 and the water, so that part of the cooling water flows out from the liquid inlet pipe 5 and is sprayed out through the spray head 15 to cool the inside of the generator 7 and the rectifier bridge support body 11, and the external circulation cooling and the internal cooling of the cooling water are performed simultaneously. When not in use, the nozzle 15 can prevent the cooling water in the water storage tank 24 from flowing out along the water pipe, and the waste of the cooling water is avoided.

When rotor plate 20 and seal box 2 sealing contact, go out liquid hole 32 and be stopped up, and the cooling water can't be thrown away from rotor plate 20 in, goes out liquid hole 32 and avoids the setting of 3 air inlets of intake pipe, produces the noise when preventing that gas from entering into feed liquor groove 31 through going out liquid hole 32.
When the rotating plate 20 is about to rotate for one circle, the chamber of the second chamber 26 rotates to the position of the pressure release valve 9, the air pressure in the second chamber 26 exceeds the threshold set by the pressure release valve 9, the pressure release valve 9 releases the pressure, at this time, the third chamber 27 rotates to the air outlet position of the air inlet pipe 3, and the third chamber 27 starts to admit air to enable the rotating plate 20 to continue to rotate. At this time, cooling water can be added into the water storage tank 24 according to needs, the cooling water flows into the hollow pipe 33 through the first one-way valve 10, when the through hole in the rotating shaft 21 corresponds to the through hole in the hollow pipe 33, the cooling water flows into the rotating plate 20 through the through hole in the rotating shaft 21, and when the rotating plate 20 rotates into the water storage tank 24, the cooling water flows into the water storage tank 24 from the liquid outlet hole 32 of the rotating plate 20.
