Description

A kind of exhaustor sealing device

Technical field

This utility model relates to exhaustor technical field, particularly relates to a kind of exhaustor sealing device.

Background technology

Exhaustor is a part for engine exhaust system, primarily serves discharge waste gas, reduces the effect of noise.Existing exhaust system is arranged on bottom of car mostly, and automobile chassis is relatively low, the problem that therefore automobile exhaust port water inlet often occurs, and then affects the normal operation of electromotor.In particularly rainwater season, a lot of surface gathered waters are serious, then easily lead to rainwater and enter engine interior as automobile parking place has hydrops from air vent；If running car is on hydrops road surface, then the problem facing automobile flameout, again start up the car and easily lead to electromotor detonation, bring unnecessary loss, entail dangers to personal safety time serious.

Utility model content

This utility model purpose is contemplated to solve the problems referred to above, propose a kind of exhaustor sealing device, it is arranged on bottom of car for existing automobile exhaust system (particularly exhaustor), face the problem into water, run Modern mechanical design theory and theory, on the basis of existing exhaustor, by exhaustor tail end being carried out the Curve guide impeller of structure, thus solving the problem that hydrops enters electromotor from air exit.

To achieve these goals, this utility model adopts the following technical scheme that

A kind of exhaustor sealing device, including exhaustor；Described exhaustor tip designs has escape pipe；Described escape pipe end face is plane；In described escape pipe, design has screw thread；Described screw thread can install rainproof plug；Described rainproof plug design has end cap；Described end cap coordinates with escape pipe end face；Carry out thread seal with escape pipe be connected by designing rainproof plug, it is possible to effectively stop rainwater to enter in electromotor, it is adaptable to automobile parking state.

Preferably, described escape pipe end face is plane；On the outer wall of described escape pipe, design has shaft seat；Described shaft seat is provided with lid of paddling；Described lid of paddling rotate axle bed rotate；Described lid of paddling coordinates with escape pipe end face.Described lid of paddling is fitted with escape pipe end face under gravity；When gas discharged by exhaustor, lid of paddling under the effect of gas separates with escape pipe end face；Forming certain aerofluxus angle, the size of aerofluxus angle depends on the pressure discharging gas；Therefore, it is possible to when not affecting aerofluxus, effectively stop hydrops thus escape pipe enters electromotor, it is adaptable to motoring condition.

Described lid of paddling is connected with shaft seat by rotating shaft.

Described rainproof plug is corrosion-resistant water proof rubber plug.

Described lid of paddling is made up of stainless steel alloy corrosion-resistant, resistant to elevated temperatures.

The end face design of described escape pipe is fluted.

Described groove be shaped as triangle or rectangle or trapezoidal or circular arc etc..

The end cover designs of described rainproof plug has projection；Described projection and the groove fit of end face, prevent rainwater from flowing in escape pipe further.

The beneficial effects of the utility model are:

This utility model is a kind of exhaustor sealing device, by designing rainproof plug, effectively prevents rainwater from entering in exhaustor, by adopting thread connecting mode, improves sealing effectiveness further, be particularly well-suited to the automobile of parked state；By designing rotating lid of paddling, make full use of the pressure discharging gas, can not only ensure that aerofluxus is discharged, moreover it is possible to effectively stop rainwater to enter in exhaustor, be particularly well-suited to the automobile of transport condition；This utility model carries out Curve guide impeller on the basis of existing exhaustor and has simple in construction, with low cost, waterproof effect clear advantage.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of this utility model escape pipe；

Fig. 3 is the structural representation of the rainproof plug of this utility model；

Wherein, 1. exhaustor, 2. acoustic filter, 3. escape pipe, 31. female threads, 32. grooves, 33. shaft seats, 34. rotating shafts, 4. rainproof plug, 41. end caps, 42. projections, 43. external screw threads, lid of 5. paddling.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, this utility model is described further:

As it is shown in figure 1, a kind of exhaustor sealing device, including exhaustor 1；Exhaustor 1 tip designs has escape pipe 3；Escape pipe 3 end face is plane；In escape pipe 3, design has female thread 31；Female thread 31 can install rainproof plug 4；The design of rainproof plug 4 has end cap 41；End cap 41 coordinates with escape pipe 3 end face；Carry out thread seal with escape pipe be connected by designing rainproof plug, it is possible to effectively stop rainwater to enter in electromotor, it is adaptable to automobile parking state.Acoustic filter 2 it is connected between exhaustor 1 and escape pipe 3.

As shown in Figure 2, it is preferred that, escape pipe 3 end face is plane；On the outer wall of escape pipe 3, design has shaft seat 33；Shaft seat 33 is provided with lid 5 of paddling；Lid 5 shaft seat 33 that rotates of paddling rotates；Lid 5 of paddling coordinates with escape pipe 3 end face；Lid 5 of paddling is fitted with escape pipe 3 end face under gravity；When gas discharged by exhaustor 1, lid 5 of paddling under the effect of gas separates with escape pipe 3 end face；Forming certain aerofluxus angle, the size of aerofluxus angle depends on the pressure discharging gas；Therefore, it is possible to when not affecting aerofluxus, effectively stop hydrops thus escape pipe enters electromotor, it is adaptable to motoring condition.

Lid 5 of paddling is connected with shaft seat 33 by rotating shaft 34.
