Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a waterproof air inlet device for a generator set. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a sound insulation system, a shock absorption system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine or other power machinery, and converts the energy generated by the flow of water, air flow, or fuel combustion into mechanical energy and transmits it to the generator, which then converts it into electrical energy and outputs it for use by electrical equipment. Generators have a wide range of applications in industrial and agricultural production, national defense, science and technology, and daily life.

[0003] At present, for the convenience of air intake, a generator set usually has an air intake structure on the air intake side. For example, in the Chinese patent document with the publication number CN202991298U and the patent name of a double-layer sound insulation air intake system for a super silent generator set, it is mentioned that "it includes a first sound insulation board, a second sound insulation board, and sound absorption cotton. There is an air inlet on the first sound insulation board, and an air outlet on the second sound insulation board. The first sound insulation board and the second sound insulation board are buckled to form a sound insulation door. The inside of the sound insulation door is hollow to form an air intake channel, and sound absorption cotton is installed in the air intake channel".
