Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example (b): as shown in fig. 1 and 2, an automatic waterproof device for an automobile exhaust pipe comprises a connecting pipe 1, a silencing plug 13 arranged in the connecting pipe 1, a tail end exhaust plate 2 arranged in the connecting pipe 1 and having a plurality of tail end exhaust holes, a sliding rod 3 inserted in the tail end exhaust plate 2, a sealing piston 6 fixedly connected with the sliding rod 3, a front end exhaust plate 4 arranged in the connecting pipe 1, a front end exhaust hole 5 arranged on the front end exhaust plate 4, and a sealing piston 6 arranged on the sliding rod 3, wherein a piston ring cavity 7 for placing the sealing piston 6 is arranged in the connecting pipe 1, and a lateral spring 9 acting on the sealing piston 6 to keep a gap 8 between the sealing piston 6 and the front end exhaust hole 5 is arranged in the piston ring cavity 7; a sealing ring cavity 10 is arranged in the connecting pipe 1, and a quick sealing mechanism 11 is arranged in the sealing ring cavity 10; the front end exhaust hole includes a front end center hole and a front end circumferential hole, the tail end exhaust plate includes a tail end center hole and a tail end exhaust hole, and the sealing piston is capable of sealing the front end exhaust hole, but in this embodiment, under normal conditions; because of the action of the lateral spring, the sealing piston 6 can not seal the front end exhaust hole, thereby ensuring the normal exhaust of the exhaust pipe; particularly, when exhausting, the piston also applies a force on the piston; in order to further guarantee the sealing effect, a quick sealing mechanism is arranged, and the exhaust pipe is quickly and effectively sealed once water enters the exhaust pipe.
The quick sealing mechanism 11 comprises a connecting rod 1101 fixedly connected with the sealing piston 6, a barb 1102 arranged at the end of the connecting rod 1101 and positioned in the sealing ring cavity 10, a thin-walled water sac 1103 arranged in the sealing ring cavity 10, water-absorbent resin 1104 and a plurality of weak portions 1105 arranged at the bottom of the sealing ring cavity 10, wherein the connecting rod 1101 penetrates through the side wall of the sealing ring cavity 10, the side wall is provided with a through hole for the connecting rod to pass through, a sealing ring 1106 for sealing the connecting rod is arranged in the through hole to prevent the moisture from entering, and the weak portions 1105 comprise a pair of upper side inclined surfaces and a pair of lower side inclined surfaces, so that the connecting rod is easy to break; a movable gap 1107 is arranged between the barb 1102 and the thin-walled water sac 1103; the sliding rod 3 is sleeved with a compression spring 12, and the elastic force of the compression spring is smaller than that of the lateral spring. When the exhaust pipe sealing device works, once water enters the exhaust pipe, the sealing piston moves towards the front end under the pressure of the water to seal the front end exhaust hole, meanwhile, the sealing piston drives the connecting rod to move forwards, so that the barb punctures the thin-wall water bag, water in the thin-wall water bag flows out and contacts with water-absorbing resin, the water-absorbing resin is preferably high-temperature water-absorbing resin, the water-absorbing resin expands instantly, the weak part is extruded and broken, and then the water-absorbing resin enters the exhaust pipe, and sealing is achieved.
