Abstract
The invention discloses an exhaust pipe protection cover arranged at the top end of a vertical exhaust pipe. The exhaust pipe protection cover comprises a protection cover body and a protection hood. The protection cover body is a hollow pipe. The inner diameter of the protection cover body is larger than the outer diameter of the exhaust pipe. The protection hood is arranged at one end of the protection cover body, shields a gas outlet of the exhaust pipe and is kept a certain distance away from the gas outlet of the exhaust pipe. The protection hood is a hollow conical hood cap. Hoops are further arranged on the protection cover body and clamped on the exhaust pipe through bolts. Multiple through gas holes are formed in the protection cover body. A poor heat conductor, namely, air, exits between the protection cover body and the exhaust pipe, and therefore the temperature of the protection cover body can be greatly lowered. Because the gas holes are formed in the protection cover body, the cooling speed of the exhaust pipe is high, and the service life is prolonged; by means of the shielding effect of the protection hood, it is avoided that sundries fall into the exhaust pipe, and normal operation of an engine is ensured; and because the protection hood is kept a certain distance away from the gas outlet of the exhaust pipe, the exhaust gas emission cannot be influenced.
