Rainproof device applied to exhaust pipe of ship emergency generator

Abstract

The rainproof device comprises a sleeve and a rain shielding disc, the rain shielding disc is in a downward arc shape, a plurality of fixing columns are fixedly connected to the upper end of the sleeve, an annular groove is formed in the lower end of the rain shielding disc, and the fixing columns are slidably connected with the inner wall of the annular groove; two threaded rods are in threaded connection with the lower portion of the side wall of the sleeve, and the ends, close to each other, of the two threaded rods rotate the inner wall of the sleeve correspondingly and are rotationally connected with arc-shaped plates. According to the device, the edge of a rain shielding disc is in a downward arc shape, so that rainwater cannot enter a sleeve after passing through the rain shielding disc and falling down, and the situation that the normal service life of the generator is affected due to the fact that the rainwater enters the generator through an exhaust pipe is avoided; and at the moment, under the action of a plurality of second springs and sound absorption cotton, the noise generated by gas flowing in the exhaust pipe can be absorbed, and the noise is prevented from affecting the normal life of people.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a rainproof device applied to the exhaust pipe of a ship's emergency generator. Background technique [0002] A ship is a means of transportation that can sail or park in waters for transportation or operation. In order to ensure that it can be used normally in an emergency, it is necessary to install an emergency generator on the ship. However, since the exhaust pipe of the emergency generator is in the Some ships cannot be arranged horizontally, so the nozzle of the exhaust pipe is placed vertically. Therefore, in order to prevent rainwater from entering the generator through the exhaust pipe and causing damage to the generator, it is necessary to add a rainproof device to the nozzle of the exhaust pipe. [0003] At present, a rain shield is simply arranged on the rainproof device at the mouth of the exhaust pipe, and the edge of the rain shield is horizontally arranged, so that ...

[0002] A ship is a means of transportation that can sail or park in waters for transportation or operation. In order to ensure that it can be used normally in an emergency, it is necessary to install an emergency generator on the ship. However, since the exhaust pipe of the emergency generator is in the Some ships cannot be arranged horizontally, so the nozzle of the exhaust pipe is placed vertically. Therefore, in order to prevent rainwater from entering the generator through the exhaust pipe and causing damage to the generator, it is necessary to add a rainproof device to the nozzle of the exhaust pipe.

[0003] At present, a rain shield is simply arranged on the rainproof device at the mouth of the exhaust pipe, and the edge of the rain shield is horizontally arranged, so that rainwater can easily enter the exhaust pipe when it flows on the rain shield. The rainproof device has a simple structure and a single function, and cannot purify the gas discharged from the exhaust pipe, so that the gas is directly discharged into the atmosphere, thereby causing environmental pollution
