Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Example 1
As shown in fig. 1-3; an integrated automobile exhaust pipe comprises a connecting flange 1 and an exhaust pipe 5, wherein the connecting flange 1 is connected to one end of the exhaust pipe 5, a heat insulation cover 2, a flexible joint 3, a catalyst 4 and a silencer 7 are sequentially arranged at one end, close to the connecting flange 1, of the exhaust pipe 5, and a breathable waterproof partition plate 6 is connected to one side face, close to one end of the connecting flange 1, of the exhaust pipe 5; the breathable waterproof partition plate 6 comprises an omega-shaped outer plate 61, a U-shaped inner plate 62, a plurality of fixing strips 63, a fixing rod 67 and bolts, wherein the fixing strips 63 are welded at two ends of the omega-shaped outer plate 61, the fixing strips 63 and the U-shaped inner plate 62 are connected with fixing blocks 65, fixing holes 66 are formed in two ends of each fixing block 65 and two ends of each fixing rod 67, and the fixing blocks 65 are connected with the fixing rods 67 through the bolts; a plurality of heat dissipation holes 69 are formed in the U-shaped inner plate 62, a plurality of breathable convex hulls 64 are formed in the omega-shaped outer plate 61, and negative pressure holes 68 are formed in one sides of the breathable convex hulls 64; the negative pressure hole 68 is formed at one side close to the silencer 7; the middle part of the omega-shaped outer plate 61 is welded with the middle part of the U-shaped inner plate 62; the heat dissipation holes 69 are arranged at two sides close to the U-shaped inner plate 62; the width of the negative pressure hole 68 is less than 10 mm; at least 2 fixing holes 66 are formed in the two ends of the fixing rod 67.
When being discharged through the exhaust pipe 5, the high-temperature tail gas is discharged through the heat shield 2, the flexible joint 3, the catalyst 4 and the silencer 7 on the exhaust pipe in sequence, the led-out high-temperature tail gas is gradually cooled along with the leading-out of the exhaust pipe, but the temperature of the front end of the exhaust pipe is relatively high; the air flow generated by the running of the automobile in the running process can enable the surface of the omega-shaped outer plate 61 to generate a negative pressure state, so that the air between the omega-shaped outer plate 61 and the U-shaped inner plate 62 is led out through the negative pressure holes 68, and the air between the exhaust pipe 5 and the U-shaped inner plate 62 is led out through the heat dissipation holes 69, so that a cycle is formed, and hot air can be quickly dissipated; the omega-shaped outer plate 61 blocks rainwater of foreign objects and rainwater of saline-alkali soil, so that the rainwater with corrosion is prevented from contacting the high-temperature exhaust pipe 5 to cause corrosion, and the service life of the exhaust pipe 5 is shortened after the corrosion occurs; fixing blocks 65 connected with the fixing strips 63 and two ends of the U-shaped inner plate 62 are fixed on the fixing rod 67 through bolts, so that the breathable waterproof partition plate 6 can be fixed on the exhaust pipe 5, and the fixing rod 67 can be directly fixed on the frame by arranging at least 2 fixing holes 66 on two ends of the fixing rod 67; the negative pressure hole 68 is formed at one side close to the silencer 7, so that the negative pressure hole 68 can generate negative pressure when the automobile runs, and rainwater splashed in the running process of the automobile is prevented from being splashed between the U-shaped inner plate 62 and the omega-shaped outer plate 61 through the negative pressure hole 68; the width of the negative pressure hole 68 is less than 10mm, so that the probability that splashed rainwater splashes between the U-shaped inner plate 62 and the omega-shaped outer plate 61 is reduced; the middle part of the omega-shaped outer plate 61 and the middle part of the U-shaped inner plate 62 are welded together, so that abnormal sound caused by collision between the middle part of the omega-shaped outer plate 61 and the U-shaped inner plate 62 in the driving process can be avoided; the U-shaped inner plate 62 and the exhaust pipe 5 are locked with two ends of the fixing rod 67 through two ends of the U-shaped inner plate 62 and the exhaust pipe 5, so that the U-shaped inner plate 62 is tightly attached to the exhaust pipe 5 to ensure that no abnormal sound occurs.
