Description

Technical Field

[0001] The utility model relates to the technical field of hovercraft equipment, and in particular to a controllable speed-removing impurity exhaust duct structure for a hovercraft engine room. Background Art

[0002] A hovercraft is a modern water vehicle that uses an air cushion and fan technology for suspension and propulsion. It is widely used in water rescue, military patrols, tourism and other related fields.

[0003] At present, hovercraft are usually equipped with air propellers and engines that can provide power, and the ventilation volume of the engine compartment is an important indicator for evaluating the quality of a compartment design. If the ventilation performance of the compartment is poor, the heat generated by the engine cannot be quickly discharged, and the temperature inside the compartment rises sharply, which in turn causes the engine to automatically shut down due to excessive temperature, affecting the normal operation of the hovercraft; at the same time, the excessively high temperature inside the compartment will also increase the risk factor of the circuit, electrical components and oil supply pipelines, affecting the safety of the hull operation.

[0004] The existing hovercraft cabin ventilation device includes a cabin cover with an engine installed inside, and an exhaust duct installed on the cabin cover for ventilation. The traditional exhaust duct structure usually only relies on the exhaust channel to correspond to the air inlet of the cabin cover for ventilation, and no special dust removal and cleaning structure design is set. During the operation of the exhaust fan blades, dust and other particles in the air are easy to gradually accumulate along the air guide path to the fan blades. When the dust and impurities reach a certain level, the ventilation performance will be reduced, thereby affecting the engine efficiency. Utility Model Content
