Abstract
The utility model discloses a tail pipe's rain-proof structure belongs to the tail pipe field, a tail pipe's rain-proof structure, including the blast pipe, blast pipe upper end outer wall fixedly connected with drainage cover, be provided with the cavity between blast pipe and the drainage cover, the blast pipe is located the tip fixedly connected with apron in the drainage cover, the square hole has been seted up on the exhaust pipe outer wall of apron below, it is fixed continuous with the blast pipe through the shrouding to drain the cover bottom, set up multiunit hole that leaks on the shrouding, the apron through the blast pipe top blocks the rainwater, makes the rainwater fall into the cavity between drainage cover and the blast pipe, then discharges the drainage cover outside through the hole that leaks on the shrouding, can prevent that the rainwater from entering into in the blast pipe, improves the protection to parts such as exhaust silencer, aftertreatment ware.
Description
Technical Field
The utility model relates to a tail pipe technical field, concretely relates to tail pipe's rain-proof structure.
Background
In some vehicles or engineering machinery, due to the arrangement requirement of the whole machine, the exhaust muffler is designed to be high. Generally, two structures of the tail pipe are provided, one structure exhausts upwards, and a rain-proof cap which is switched according to whether exhaust airflow exists is additionally arranged; one is provided with a bent pipe for exhausting air to the side or the side rear part; the two structures can not effectively prevent rainwater from entering parts such as an exhaust silencer, an aftertreatment device and the like in a rainstorm environment; particularly for vehicles discharged by more than four countries, the high-temperature ceramic carrier in the post-processor is in cracking risk due to the entering of rainwater.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model aims to provide a tail pipe's rainproof structure blocks the rainwater through the apron on blast pipe top, makes the rainwater fall into the cavity between water drainage cover and the blast pipe, then falls into on the shrouding of cavity bottom, discharges the water drainage cover outside through the hole that leaks on the shrouding, can prevent that the rainwater from entering into in the blast pipe, improves the protection to parts such as exhaust silencer, aftertreatment ware.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides a tail pipe's rain-proof structure, includes the blast pipe, blast pipe upper end outer wall fixedly connected with drainage cover, be provided with the cavity between blast pipe and the drainage cover, the blast pipe is located the tip fixedly connected with apron in the drainage cover, the square hole has been seted up on the apron below blast pipe outer wall, the drainage cover bottom is passed through the shrouding and is fixed continuous with the blast pipe, the multiunit hole that leaks has been seted up on the shrouding.
As a further aspect of the present invention: the diameter of the cover plate is 10mm larger than that of the exhaust pipe.
As a further aspect of the present invention: the top of the drainage cover is fixedly connected with a bent pipe.
The utility model has the advantages that:
the utility model discloses in, the apron through the blast pipe top blocks the rainwater, makes in the rainwater falls into the cavity between water drainage cover and the blast pipe, and the hole that leaks on the rethread shrouding discharges the water drainage cover outside, can prevent that the rainwater from entering into in the blast pipe, improves the protection to parts such as exhaust silencer, aftertreatment ware.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the internal structure of the drain cover of the present invention;
fig. 3 is a schematic view of the overall structure of the middle exhaust pipe of the present invention.
In the figure: 1. an exhaust pipe; 101. a square hole; 102. a cover plate; 2. a drain cover; 201. a cavity; 202. closing the plate; 2021. a water leakage hole; 3. and (5) bending the pipe.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-3, a rain-proof structure of tail pipe, including exhaust pipe 1, exhaust pipe 1 upper end outer wall fixedly connected with drain cover 2, drain cover 2 top fixedly connected with return bend 3, be provided with cavity 201 between exhaust pipe 1 and the drain cover 2, the tip fixedly connected with apron 102 that exhaust pipe 1 is located drain cover 2, square hole 101 has been seted up on the exhaust pipe 1 outer wall below apron 102, drain cover 2 bottom is passed through shrouding 202 and is fixed continuous with exhaust pipe 1, multiunit hole 2021 that leaks has been seted up on shrouding 202.
The apron 102 diameter is 10mm bigger than the diameter of blast pipe 1, is convenient for carry out the separation to the rainwater, prevents to enter into inside blast pipe 1 from square hole 101.
The utility model discloses a theory of operation: the rainwater enters into drainage cover 2 through return bend 3 in, apron 102 through 1 top of blast pipe blocks the rainwater, make the rainwater fall into drainage cover 2 and blast pipe 1 between cavity 201 in, then fall into on the shrouding 202 of cavity 201 bottom, discharge the drainage cover 2 outside through the hole 2021 that leaks on the shrouding 202, can prevent that the rainwater from entering into blast pipe 1 in, the improvement is to the exhaust silencer, the protection of parts such as aftertreatment ware, simultaneously during the work exhaust of blast pipe 1, gas enters into in the blast pipe 1, then discharge in the cavity 201 through the square hole 101 of 1 upper end both sides of blast pipe, then discharge through return bend 3.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
