Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 3, according to the silencing apparatus of a kind of rainwater-proof of the specific embodiment of the invention, comprise muffler body 1, draining ring 2, smoke-ejecting pipe 3 and hoop 4.Particularly, the bottom of muffler body 1 has exhaust gas intake port end 14, and its top is provided with exhaust outlet end 13.As a kind of preferred embodiment, the outer wall of muffler body 1 is cylindrical shell 11, the two ends of cylindrical shell 11 are closed by end buckle 12, the inner chamber interval of cylindrical shell 11 arranges two dividing plates 16, the inner chamber of cylindrical shell 11 is divided into the first chamber, the second chamber and the 3rd chamber (unmarked in figure) by these two dividing plates 16 successively, be provided with two groups of hush tubes 17 between these two dividing plates 16, often organize hush tube 17 and at least comprise three, the present embodiment is for 3.Particularly, hush tube 17 can design according to shown in Fig. 1, often organize hush tube 17 tube wall on be through with some through holes, wherein the chamber (the first chamber) of the left end (inlet end) of one group of hush tube 17 dividing plate and left end that run through left end is communicated with, the right-hand member of this group hush tube 17 is closed by the dividing plate of right-hand member, namely this group hush tube is communicated with intermediate cavity (the second chamber), equally, the chamber (the 3rd chamber) of dividing plate and right-hand member that another right-hand member (outlet side) organizing hush tube 17 runs through right-hand member is communicated with, the left end of this another group hush tube 17 is closed by the dividing plate of left end, namely this another group hush tube is communicated with right-hand member chamber (the 3rd chamber).In addition, cylindrical shell 11 is thin-wall parts, exhaust gas intake port end 14 and the first chamber are connected, exhaust outlet end 13 and the 3rd chamber, the muffler body of such design, operationally, engine exhaust enters the first chamber of silencing apparatus by exhaust gas intake port end 14, the second chamber is entered again by three hush tubes 17, then be also enter the 3rd chamber by three hush tubes 17, discharge finally by exhaust outlet end 13, the filtration of waste gas to acoustic energy in the propagation of sound process by three resonant cavities and 6 hush tubes, principle of reflection has cut down kinetic energy, thus noise is reduced in the scope of regulation permission.
In addition, draining ring 2 is sleeve-shaped, is axially arranged with some grooves 21 (see Fig. 4) along sleeve on the outer wall of this sleeve, and draining ring 2 is located at exhaust outlet end 13.In the present embodiment, exhaust outlet end 13 has adapter, and draining ring 2 is welded on (see Fig. 1) on the outer wall of adapter.Finally, the bottom of smoke-ejecting pipe 3 is plugged on the outer wall of draining ring 2, groove 21 forms flow channel (not shown) with the tube wall of smoke-ejecting pipe 3, and with hoop 4 by the bottom banding of smoke-ejecting pipe 3 on draining ring 2, as a kind of preferred embodiment, the top of smoke-ejecting pipe 3 has bending section 31 (see Fig. 3), and the bottom tube wall of smoke-ejecting pipe 3 has some distortion grooves 32, distortion groove 32 is U-groove bevel, U-groove bevel spaced set (see Fig. 7).
As shown in Figure 5, hoop 4 by hoop body 41, nut 42, spring washer 43, bolt on 44, square flat gasket 45 forms, its function is the deformable by hoop body 41, then by nut 42, bolt on 44 and lock.
As shown in Figure 6, when concrete installation smoke-ejecting pipe 3, unclamp hoop 4, and be enclosed within the bottom of smoke-ejecting pipe 3, then the bottom of smoke-ejecting pipe 3 is enclosed within the outer wall of draining ring 2 together with hoop 4, bottom due to smoke-ejecting pipe 3 has distortion groove, and distortion groove has elasticity, finally, locking ring collar 4, can be fixed on the outer wall of draining ring 2 by smoke-ejecting pipe 3, now, the groove 21 on the outer wall of draining ring 2 is just combined into the passage of discharging rainwater with the inwall of the bottom of smoke-ejecting pipe 3.
So far, such silencing apparatus, the bending section 31 on the top of its smoke-ejecting pipe 3 makes rainwater can not vertically drop into smoke-ejecting pipe 3, and the rainwater tiltedly waftd can be fallen after entering smoke-ejecting pipe 3 on smoke-ejecting pipe 3 inwall, then the inwall along smoke-ejecting pipe 3 flows down, discharged by above-mentioned drainage channel, and the waste gas of motor is when flowing through smoke-ejecting pipe 3, air-flow velocity in smoke-ejecting pipe 3 is higher, air pressure is low, outside air enters smoke-ejecting pipe 3 by the groove 21 of draining ring 2, and the waste gas of motor can not be caused to flow out from the groove 21 of draining ring 2.Even if there is few part rainwater to enter in the cylindrical shell of silencing apparatus; because exhaust gas intake port end 14 is located at the bottom of cylindrical shell 11; and the inwall of cylindrical shell 11 is protruded in the adapter of exhaust gas intake port end 14; so rainwater can not enter in motor; can evaporate when engine operation, thus the use safety of protection motor.
In addition, the bottom of muffler body 1 is also provided with support tube 15, the end of support tube 15 is provided with pivot flange 151, exhaust gas intake port end 14 has adapter, the end of this adapter has mounting flange 141, the joint of the adapter of exhaust outlet end 13 and the joint of cylindrical shell 11, the adapter of exhaust gas intake port end 14 and the joint of cylindrical shell 11 and support tube 15 and cylindrical shell 11 is equipped with stiffening ring (see unmarked in Fig. 1, figure).
To sum up, the present embodiment, by providing a kind of draining ring 2, can realize the rainwater-proof function of silencing apparatus, neither changes original complete machine and arranges, its cost is suitable with common silencing apparatus cost again, is that a kind of structure is simple, practical silencing apparatus.Meanwhile, by arranging three resonant cavities and hush tube 17, rainproof function can be reached, meet decrease of noise functions again.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
