Abstract
The utility model relates to a drainage mechanism of a muffler, which comprises a drainer, wherein the drainer is arranged in the muffler near a gas outlet, and the drainer comprises vanes which can rotate to the vicinity of the gas outlet and bottom accessories of the muffler. The gas exhausted from the muffler drives the vanes to rotate. In the rotating process of the vanes, the vanes which rotate from the lowest point lift the accumulated water in the muffler to an exhaust cycle channel near the gas outlet, thus the accumulated water is taken out of the muffler by the exhausted gas.
Description
Technical field
The utility model relates to the mechanism in a kind of silencing apparatus, and especially, the utility model relates to a kind of drainage mechanism of silencing apparatus.
Background technique
On automobile, the effect of silencing apparatus is the noise that reduces engine exhaust, and the noise when making vehicle operating reduces.Continuous development along with the three-element catalytic technology contains a large amount of water vapour in the vehicle exhaust, when tail gas moved in silencing apparatus, along with the reduction of temperature, part water vapour will condense into water and stay in the silencing apparatus, thereby forms ponding in the silencing apparatus bottom.Because the shell of silencing apparatus is a metal solder mechanism, long-term ponding can make silencing apparatus get rusty, and especially can cause weld to get rusty, and makes the weld Cracking Failure when serious, influences the working life of silencing apparatus.
For the ponding problem in the silencing apparatus, a kind of solution known today is that the outlet end pipeline to silencing apparatus designs, such as the design of trend, pipeline special entity.By this design, when making driving, the ponding near gas outlet in the silencing apparatus is taken out of by flowing of exhaust.But also there is following deficiency in this solution, advances or is in idling operation for a long time when the long-time low speed of vehicle, and when air-flow velocity was very little, ponding still can't fully be discharged.
Another kind of solution is to carry out artificial drainage, promptly in the process of travelling, step on the gas suddenly after high rotating speed gear shift or the parking, by strengthening the exhaust flow velocity ponding in the silencing apparatus is taken out of, but this method needs driver people for carrying out draining, has increased driver's workload.
The model utility content
The utility model proposes at the problems referred to above, and purpose provides a kind of drainage mechanism of silencing apparatus, and the drainage mechanism of this silencing apparatus can be realized good drainage effect with a kind of simple mechanism.
The drainage mechanism of silencing apparatus of the present utility model comprises hydathode, and described hydathode is arranged in the silencing apparatus near gas outlet, and described hydathode comprises and can rotate near the described gas outlet and the blade of the bottom annex of described silencing apparatus.
The beneficial effects of the utility model are: in the drainage mechanism of this silencing apparatus, because described hydathode is arranged in the silencing apparatus near gas outlet, and described hydathode comprises and can rotate near the described gas outlet and the blade of the bottom annex of described silencing apparatus, drive vane rotation when therefore the gas in the silencing apparatus is discharged, in rotary course, blade contacts with the ponding of silencing apparatus bottom when minimum point turns over and ponding is taken up near the gas outlet the exhaust circulation path, and the gas that ponding is discharged from is taken silencing apparatus out of.

Embodiment
Embodiment one
As shown in Figure 1 to Figure 3, the drainage mechanism of the silencing apparatus of present embodiment comprises hydathode 2, and hydathode 2 comprises: runner 21, rotating shaft 24, left socle 25a, right support 25b, left bearing 26a, right bearing 26b, left rotary shaft back-up ring 29a, right spindle back-up ring 29b, left bearing back-up ring 28a, right bearing back-up ring 28b, left wheel back-up ring 27a and right wheel back-up ring 27b.Hydathode 2 is installed in close gas outlet 11 places in the silencing apparatus 1, and its left socle 25a and right support 25b are fixed on the bottom of silencing apparatus 1 by welding or bolted mode.Arrow among Fig. 1 represents to discharge the gas flow direction.
6 equally distributed blades 22 are arranged on the excircle of runner 21, and there is a big square opening 23 centre of each blade 22, and the effect of square opening 23 is the resistances that reduce to discharge air-flow in silencing apparatus 1 when hydathode 2 is rotated.Blade 22 reaches near the bottom of silencing apparatus 1 near can rotate to gas outlet 11.
Left rotary shaft back-up ring 29a, right spindle back-up ring 29b, left bearing back-up ring 28a, right bearing back-up ring 28b, left wheel back-up ring 27a and right wheel back-up ring 27b are the elastic caoutchouc back-up ring.
Be connected with 26b by two bearing 26a between runner 21 and the rotating shaft 24, the outer ring of bearing 26a and 26b is installed in the center hole of runner 21, the inner ring of bearing 26a and 26b is installed in the rotating shaft 24, two end ring 28a and 28b is installed in rotating shaft 24 is used for limiting bearing 26a and 26b moving along the axial direction of rotating shaft 24 respectively.Two runner back-up ring 27a and 27b also are installed in rotating shaft 24, the end face of two runner back-up ring 27a and 27b respectively with the left and right sides end surfaces of runner 21, with restriction runner 21 moving along the axial direction of rotating shaft 24.The two ends of rotating shaft 24 are respectively installed in the mounting hole of left socle 25a and right support 25b, near the left side of left socle 25a and the place, right side of right support 25b two rotating shaft back-up ring 29a and 29b are installed respectively in rotating shaft 24, the effect of rotating shaft back-up ring 29a and 29b is to prevent rotating shaft 24 moving relative to left socle 25a and right support 25b.
When engine running produced exhaust, the gas of discharge arrived silencing apparatus 1 through various pipelines and discharges from the gas outlet 11 of silencing apparatus 1.Because hydathode 2 is installed in the silencing apparatus 1 near gas outlet 11 places, so the gas in the silencing apparatus 1 drives the blade 22 on the runner 21 when discharging, and makes blade 22 24 rotations around the shaft; In blade 22 rotary courses, because blade 22 can rotate near the bottom of silencing apparatus 1, so if ponding is arranged at silencing apparatus 1 bottom, the blade 22 that then turns over from minimum point contacts with ponding certainly and part ponding is taken up near the discharge gas passageway of gas outlet 11, and the gas that ponding is discharged from is taken silencing apparatus 1 out of.
Embodiment two
Shown in Figure 4 is the schematic appearance of hydathode 2 among the utility model second embodiment.In a second embodiment, use with first embodiment in identical reference character represent corresponding with it constituting component, the repetitive description thereof will be omitted, wherein different parts described.
There is a big square opening 23 different with the centre of each blade 22 on the runner 21 among first embodiment, in a second embodiment, on each blade 22 on the runner 21 many apertures 33 are arranged all, the effect of these apertures 33 is identical with the effect of square opening 23 among first embodiment, also is the resistance that reduces to discharge air-flow in silencing apparatus 1 when hydathode 2 is rotated.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
