Automatic smoke exhaust device for vehicle-mounted oil machine

Abstract

The invention discloses an automatic smoke discharge device for a vehicle-mounted oil engine. The automatic smoke discharge device comprises a fixed air flue, a movable air flue, a seal ring and a movable air flue automatic-resetting mechanism, wherein the fixed air flue is fixed on a carriage wall, the movable air flue is embedded in the fixed air flue, multiple smoke evacuation openings are radially and uniformly distributed at in the front end of the movable air flue, the seal ring is fixed on the front end face of the fixed air flue, the rear end of the movable air flue is connected with a vehicle-mounted oil engine power station air outlet; the movable air flue automatic-resetting mechanism comprises a pair of support rods and a pair of seal pipes, the pair of seal pipes are symmetrically fixed on two sides of the fixed air flue, the pair of support rods are respectively embedded in the pair of seal pipes, pistons radially extend from the middles of the support rods, the front ends of the support rods pass through the seal ring and then are fixedly connected with end enclosure end plates, and the rear ends of the support rods penetrate pass out of the rear end of the fixed flue; the front end diameter of each support rod in a front cavity of the corresponding each seal pipe is smaller than the rear end diameter of each support rod in a rear cavity of the corresponding seal pipe. The automatic smoke discharge device is simple in structure, convenient to make, low in cost, high in reliability and convenient to use and maintain, and automatic exhaust gas discharge of the vehicle-mounted oil engine is realized.

Description

technical field [0001] The invention relates to a smoke exhaust device for a vehicle-mounted generator set, in particular to a smoke exhaust device for an internal combustion engine-generator set installed in a shelter or a van, and belongs to the technical field of vehicle accessory equipment. Background technique [0002] At present, the application of special vehicles or equipment for field operations and combat, such as shelters or vans, is becoming more and more widely used. Limited by the fact that there is often no electricity supply in the field, shelters or vans are equipped with on-board oil motors. station (internal combustion engine-generator unit) to meet work needs. The vehicle-mounted diesel engine power station is installed in the enclosed space of the shelter or van. The suction and exhaust device of the diesel engine is a necessary guarantee for the normal operation of the personnel and equipment in the shelter or van. Therefore, the demand for automatic s...
