Diesel locomotive power room and transmission room sealing isolation device

Abstract

The invention discloses a device for sealing and isolating a dynamic chamber and a transmission chamber of an internal combustion locomotive. The device has a baffle-type structure which is in a partition wall with a hole shape. The periphery of a baffle 1 is fastened to a partition wall 5 through a bolt 7, a round hole is arranged in the center of the baffle 1 and the round hole corresponds with the ventilation opening of a main generator 6, the baffle 1 is prepared from rigid materials such as steel plates, a cylinder 2, which is concentric with the round hole, is arranged around the round hole on the side which faces the dynamic chamber on the baffle 1, a sealing adhesive tape 3 is embedded in the free end of the cylinder 2, a filter screen 4 which is composed of two semi-circle is arranged on the side which faces the transmission chamber, and a round hole, which matches with the output shaft 8 of the main generator, is arranged in the center of the filter screen 4. The device has a good sealing effect, and provides a high guarantee for the air insulation between a dynamic chamber and a transmission chamber. In the assembly process, the number of the blots that need to be tightened is largely reduced, and thus the operation is more convenient. Furthermore, a filter screen is added, so that the cleaning period of the main generator is prolonged.

Description

technical field [0001] The invention relates to a sealing isolation device for a power chamber and a transmission chamber of a diesel locomotive, belonging to the technical field of railway locomotives. Background technique [0002] The diesel generator set of the diesel locomotive is placed in the power room, and the output end of the main generator passes through the partition wall to the transmission room. The air intake end of the main generator is also facing the transmission room, and the clean air with a lower temperature is sucked in the transmission room for cooling; because the air temperature in the power room is higher, the air pressure is often higher than that in the transmission room, so it must be installed between the power room and the transmission room. The partition walls between the chambers should be sealed to prevent the hot air in the power chamber from entering the transmission chamber and keep the air in the transmission chamber at a lower temperatu...

AI Technical Summary

Problems solved by technology

[0004] (1) The baffle cloth is made of flexible material. Even if denser bolts are used to pass through the round holes to connect and fix the partition wall and the main generator, it cannot ensure the close fit and tightness of the baffle cloth with the partition wall and the main generator. sex is not ideal

[0005] (2) The operation of tightening the bolts during the installation process is relatively large

Before installing the baffle cloth, first remove the bolts from the main generator end cover one by one, and then screw these bolts through the small round holes on the main generator baffle cloth to the main generator end cover, the operation is very troublesome
