Noise reduction and smoke guiding device for vehicle-mounted square cabin diesel generator set

Abstract

The invention relates to a noise reduction and smoke guiding device for a vehicle-mounted square cabin diesel generator set, and is characterized in that: a fixing flange (2) is fixed to the vehicle-mounted square cabin roof (1) by a first bolt (10), one end of the sound-absorbing elbow (3) is welded with the fixing flange (2), the other end of the sound-absorbing elbow (3) is connected with one end of the diameter-changing muffler pipe (4), the other end of the variable diameter muffler pipe (4) is inserted and fixed into an air inlet hole (11) on the inlet side of the expansion chamber (5),a single-layer micro-perforated plate (6) is arranged on the exhaust side of the expansion chamber (5), and a smoke guide groove (7) is oppositely arranged on the exhaust side of the expansion chamber(5), and the smoke guide groove (7) is fixed on the cabin top (1) of the vehicle by a fixing frame (8) by a second bolt (12). The invention solves the noise reduction problem of the smoke exhaust device under the condition of limited space, and can effectively prevent rainwater from entering the smoke exhaust pipe, thereby ensuring the normal and stable operation of the vehicle-mounted square cabin diesel generator set.

Description

technical field [0001] The invention belongs to the technical field of smoke exhaust devices for vehicle-mounted shelter generator sets, and in particular relates to a noise-reducing, noise-reducing and smoke-guiding device for vehicle-mounted shelter diesel generator sets. Background technique [0002] The vehicle-mounted shelter diesel generator set uses a diesel engine as the power source. The energy generated by diesel combustion is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy by the generator to realize the power supply of the vehicle-mounted equipment. When the diesel engine is working, part of the fuel energy is used to generate power, and most of the fuel energy is converted into combustion exhaust gas and body heat. The vehicle-mounted shelter diesel generator set is installed at the bottom of the shelter, the smoke exhaust is connected to the top of the shelter through pipes, and fixed to the top ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of exhausting smoke on the top of the vehicle-mounted shelter diesel generator set and improve the working environment of the operators. A noise reduction and noise-reducing smoke-guiding device for the vehicle-mounted shelter diesel generator set is designed. The device passes through the flange It is connected and installed on the top of the vehicle shelter, and the exhaust gas generated by the diesel generator set is discharged out of the vehicle shelter through the exhaust pipe
