Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the rainproof type muffler includes a muffler main body 3 fixed on the top of a soundbox 2 through a mounting base 1 and a pipe 4 for communicating the muffler main body 3 with a generator set, the pipe 4 passes through the soundbox 2 through a flange hole, the pipe 4 is sleeved with a rainproof assembly 5, the rainproof assembly 5 covers the flange hole, the rainproof assembly 5 is in an umbrella shape with an opening at the top, the rainproof assembly 5 includes a first slope 6, a second slope 7 and a third slope 8 which are sequentially arranged from top to bottom, and both opening angles of the first slope 6 and the third slope 8 towards the top of the soundbox 2 are greater than those of the second slope 7 towards the top of the soundbox 2; that is to say, when the rain water contacts the rain-proof component 5, the rain water firstly passes through the first slope 6 with a smaller gradient, and then passes through the second slope 7 with a larger gradient, and then the gradient is increased, so that the downward sliding speed of the rain water is increased, and finally the rain water passes through the third slope 8 with a smaller gradient, so that the acceleration of the second slope 7 in the horizontal direction enables the rain water to rapidly flow through the rain-proof component, and the rain water on the mute box 2 and the periphery of the third slope 8 can also impact the rain water on the mute box 2, so that the rain water on the mute box 2 does not permeate towards the flange hole, and the rain-proof effect; the rain-proof component 5 can be formed into an umbrella shape by welding a first slope surface 6, a second slope surface 7 and a third slope surface 8, or an integral section can be processed into the umbrella shape with three slope surfaces by equipment;

be equipped with external screw thread 9 on the pipeline 4 outer wall, still be equipped with on the pipeline 4 through the knob 10 of external screw thread 9 swivelling joint, knob 10 supports and presses the top of first domatic 6, knob 10 with be equipped with rubber gasket 11 between the top of first domatic 6. By rotating the knob 10 downwards, the distance between the knob 10 and the top of the mute box 2 is reduced, so that the rubber gasket 11 is reliably compacted, meanwhile, the contact gap between the third slope surface 8 and the top of the mute box 2 is reduced, rainwater is ensured not to permeate into the rainproof assembly 5 from the joint of the first slope surface 6 and the pipeline 4 and the joint of the third slope surface 8 and the top of the mute box 2, and rainwater is also prevented from permeating into the mute box 2 from the flange hole; further, the rainproof performance of the rainproof assembly 5 can be reinforced only by jacking the screwing knob 10, the replacement period of the rubber pad is reduced, the structure is exquisite, the rainproof effect is remarkable, and the later maintenance is simple and convenient.

A water absorbing felt 12 is clamped between the inner wall of the flange hole and the outer wall of the pipeline 4, a water receiving kettle 14 is installed on the pipeline 4 through a support frame 13, the water receiving kettle 14 is located in the mute box 2, an opening 15 is formed in the top of the water receiving kettle 14, the upper portion of the water absorbing felt 12 is clamped in the flange hole, and the lower portion of the water absorbing felt penetrates through the opening 15 and is suspended in the water receiving kettle 14. When the waterproof assembly is damaged or is not maintained for a long time, rainwater can be absorbed by the water absorbing felt 12 when permeating from the flange hole, the absorbed rainwater moves to the lower part of the water absorbing felt 12 under the action of gravity, and after the water absorbing felt 12 is saturated, the rainwater can enter the water receiving pot 14 along the water absorbing felt 12, so that the rainwater is prevented from permeating into the sound box 2 and then damaging the generator set; connect and do not have the contact between kettle 14 and the pipeline 4, because the felt 12 parcel that absorbs water is in the periphery of pipeline 4 for connect the opening 15 at kettle 14 top also to become corresponding annular, through the felt 12 that absorbs water with connect the cooperation of kettle 14, effectively prevent that the defence subassembly from damaging the back, the rainwater gets into in the silence case 2, provides the second for the rain-proof performance of silence case 2 and ensures again.

A supporting plate 16 is further arranged between the water receiving kettle 14 and the top of the silence tank 2, the supporting plate 16 inclines downwards, and the supporting plate 16 supports the water absorbing felt 12 in a supporting mode. The supporting plate 16 is arranged between the water absorbing felt 12 and the pipeline 4, the outer edge of the supporting plate 16 is in contact with the water absorbing felt 12, the water absorbing felt 12 is lifted due to the fact that the supporting plate 16 inclines downwards, on one hand, the lower portion of the water absorbing felt 12 enters the water receiving pot 14 in a vertical state, on the other hand, a small amount of rainwater dropping on the supporting plate 16 flows downwards in an inclined mode and is absorbed by the water absorbing felt 12 again, therefore, the rainwater absorbed by the water absorbing felt 12 can all enter the water receiving pot 14, namely, the rainwater can only flow along the water absorbing felt 12 after being absorbed by the water absorbing felt 12 at the flange hole and does not contact with the outer wall of the pipeline 4 any more, and the rainproof reliability is guaranteed.

The bottom of the water receiving kettle 14 is provided with a water outlet valve 17. The outlet valve 17 is opened at intervals to take away the rainwater dropping from the water-absorbing felt 12, so as to prevent the rainwater from overflowing from the water receiving pot 14.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
