Embodiment Construction

[0009] like figure 1 As shown in the figure, a retractable exhaust pipe cabin is composed of a heat insulating material 1 and a sleeve 2. The sleeve 2 is placed on both sides of the exhaust pipe 6 through the heat insulating material 1. On the sleeve 2 A bulkhead 8 is provided, the bulkhead 8 is vertically provided with an installation seat plate 3, and the installation seat plate 3 is horizontally provided with a rainproof cover 5, and the other end of the rainproof cover 5 is placed on the exhaust pipe 6, and the rainproof cover A water retaining ring 4 is provided between 5 and the casing 2 .

[0010] The rainproof cover 5 is provided with a drain hole 7 .

[0011] The principle is as follows:

[0012] The casing 2 is welded on the opening of the bulkhead 8, and the water retaining ring 4 is spot welded on the exhaust pipe 6 when the pipe is prefabricated. After the exhaust pipe 6 is positioned, it is adjusted to a suitable position and then the water retaining ring 4 is ...

Abstract

The invention relates to a retractable type exhaust pipe penetration piece. The retractable type exhaust pipe penetration piece includes a heat insulation material and a bushing; the bushing is arranged at two sides of an exhaust pipe through the heat insulation material; the bushing is provided with a bulkhead; the bulkhead is vertically provided with a mounting base plate; the mounting base plate is horizontally provided with a rain cover; one end of the rain cover is arranged on the exhaust pipe; and a water deflector is arranged between the rain cover and the bushing. With the retractable type exhaust pipe penetration piece of the invention adopted, heat emitted by the exhaust pipe can be isolated, so that the heat will not be transferred to the bulkhead and can be prevented from damaging the paint of the bulkhead; rain water can be prevented from entering the inner side of the bulkhead, and thermal expansion of the exhaust pipe will not be transferred to the bulkhead assuredly, and the exhaust pipe can stretch and contract axially.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a retractable exhaust pipe opening. Background technique [0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust The pipe generally includes a front exhaust pipe and a rear exhaust pipe. [0003] There is a hatch on the exhaust pipe to protect the exhaust pipe, but the traditional hatch cannot prevent rain well, nor does it have a good heat insulation effect, and it cannot be easily changed, and its performance is poor. SUMMARY OF THE INVENTION [0004] In order to overcome the above problems, the present invention adopts the following technical solutions: [0005] A retractable exhaust pipe cabin, which consists of he...
