Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a double-layer silent diesel-electric hybrid generator set with high utilization rate. Background Art

[0002] The diesel-electric hybrid generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. The generator set consists of a power system, a control system, a silencer system, a shock absorption system, and an exhaust system. The principle is that when the diesel generator set shrinks in size, the temperature rises rapidly, reaching the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, and the volume expands rapidly, pushing the piston downward, which is called "work". Each cylinder works in a certain order, and the thrust acting on the piston is transformed into a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. Using the principle of "electromagnetic induction", the generator will output an induced electromotive force and generate current through a closed load circuit. The types of generator sets include diesel generator sets, gas generator sets, gasoline generator sets, etc.

[0003] Currently, most diesel-electric hybrid generator sets are arranged in a single layer, which occupies a large space. In order to solve the problem of low space utilization, diesel-electric hybrid generator sets are often arranged in a double-layer juxtaposition manner.

[0004] However, the double-layer diesel-electric hybrid generator set in the prior art generates large vibrations when working. When the vibrations act on the ground through the lower diesel-electric hybrid generator set, noise will be generated. The noise seriously affects the hearing of the workers in the working environment. Working in a noisy environment will affect work efficiency and production efficiency, which is very harmful. In view of this, we propose a high-utilization double-layer silent diesel-electric hybrid generator set. Utility Model Content
