Radial type flexible smoke exhausting device

Abstract

The invention belongs to the field of auxiliary systems of engine compartments of special vehicles, and particularly relates to a radial type flexible smoke exhausting device. The radial type flexible smoke exhausting device comprises a connecting part in a compartment and a smoke exhausting part outside the compartment, the connecting part in the compartment is formed by a conical air ducting cylinder, a flexible corrugated tube and a heat insulating asbestosed wire gauze from inside out, the smoke exhausting part outside the compartment is formed by a conical air ducting cylinder and a heat insulating asbestosed wire gauze, via the connecting part and the smoke exhausting part which serve as two connecting units, a smoke exhausting pipe of an engine is extended by penetrating through a power station compartment to outside of the power station compartment, so that smoke exhausting requirements of a vehicle-mounted power station mounted on a special vehicle are met. By the aid of the radial type flexible smoke exhausting device, the defect of a smoke exhausting structure of an existing vehicle-mounted power station engine is overcome, exhaust resistance of the power station is lowered, breakage of the smoke exhausting device is avoided, assembling is simplified, smoke exhausting thermal radiation is lowered, and water resisting performance is improved.

Description

technical field [0001] The invention belongs to the field of special vehicle engine compartment auxiliary systems, and in particular relates to a radial flexible smoke exhaust device. Background technique [0002] The vehicle-mounted power station is installed in an independent and airtight compartment inside the special vehicle. When the power station is working, the engine will discharge hot exhaust gas out of the cabin. The existing method is to insert one end of the smoke exhaust extension pipe into the engine smoke exhaust pipe and fasten it with a clamp, and the other end directly passes the smoke exhaust port out of the cabin, or the other end is transition welded to the smoke exhaust port on the inner wall of the cabin through a bellows . The defects in the existing methods are as follows: 1. In the first way, the smoke exhaust extension pipe is hard-connected and installed without buffering. The vibration causes the smoke exhaust device to break and damage easily;...

AI Technical Summary

Problems solved by technology

The defects in the existing methods are as follows: 1. The smoke exhaust extension pipe in the first method is hard-connected and installed without buffering. The vibration causes the smoke exhaust device to break and damage easily; seal

2. In the second method, the smoke exhaust extension pipe needs to be welded and fixed first, which increases the difficulty of welding process and assembly

3. The smoke exhaust extension pipe adopts the pipeline with the same aperture, and the extended pipeline leads to enhanced smoke exhaust resistance (reduces engine power)

4. There is no effective heat insulation treatment on the outer surface of the smoke exhaust extension pipe, and the heat radiation of the smoke exhaust increases (the cabin is overheated, and the power station cannot work normally; the external heat radiation of the vehicle increases, reducing the concealment)

5. There is no rainproof measure for the external smoke exhaust port, and rainwater is easy to pour back into the engine from the smoke exhaust port
