Technical Field

[0001] This utility model relates to the technical field of under-mounted diesel generator sets for railway passenger cars and engineering vehicles, and in particular to a generator set and its anti-sand and snow protection device. Background Technology

[0002] Currently, oil bath air filters are commonly used in under-mounted diesel generator sets for railway passenger cars and engineering vehicles. However, they are not very effective at preventing dust and sand when the vehicles are out in operation. Working in dusty environments can easily cause diesel engine cylinder scoring, resulting in a high failure rate of the generator set. Furthermore, it is inconvenient to change the oil in the air filter and clean the filter element while the vehicle is in operation.

[0003] In terms of protective structure, the current units generally use door panels and baffles with waist holes to protect the diesel engine, generator and other unit components. In the environment of strong winds, sandstorms and snow, a large amount of sand and snow can accumulate inside the unit, which can cause the moving parts inside the unit to jam and the insulation of electrical components to drop, resulting in the unit not being able to work normally and reducing its service life.

[0038] Another implementation method is, as Figure 1-9 As shown, a generator set of this utility model has the aforementioned generator set anti-sand and snow device.

[0039] This invention replaces the door panels and baffles around the unit, which require high-flow-rate air intake and exhaust for heat dissipation, with air intake and exhaust regulating valves. Because the installation structure is the same as the original door panels and baffles, they can be quickly disassembled and replaced. The regulating valve handle is a toggle type or handwheel type, allowing for manual and rapid adjustment of the blade opening to control the ventilation volume. Multi-mesh stainless steel wire mesh plates are installed on the top of the unit, on the door panels, baffles, and regulating valves. This satisfies the unit's heat dissipation requirements while effectively preventing strong winds, sandstorms, and snow from entering the unit. The mesh plates behind the door panels, baffles, and regulating valves are connected to the unit base 1 or the door panels, baffles, and regulating valves by bolts, screws, or rivets, allowing for easy disassembly and replacement.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
