Abstract

The invention provides smoldering smoke particle collecting equipment for an electrical conductor, which comprises a smoke generating device, a smoke collecting cover and a ventilating pipe, wherein the smoke generating device is provided with a power supply; the smoke collecting cover is arranged on the smoke generating device and further forms a smoke collecting chamber with the smoke generating device; the ventilating pipe is communicated with the smoke collecting chamber; the smoke collecting cover and the ventilating pipe are both provided with a smoke particle collector; the smoke particle collectors comprise collecting barrels, electromagnets, protecting sleeves and movable rods; springs and iron columns are arranged in the collecting barrels; one ends of the springs are connected with the bottom ends of the collecting barrels; the iron columns are connected with the springs; the electromagnets are connected with the power supply and are further all positioned at the other endsof the springs together with the iron columns; the protecting sleeves are connected with the collecting barrels; the movable rods are sleeved in the protecting sleeves in a sliding way and are further connected with the iron columns; and the movable rods are provided with smoke particle collecting meshes. By using the smoldering smoke particle collecting equipment for the electrical conductor, which is provided by the invention, the automatic collection of the smoldering smoke particles of the electrical conductor is achieved; a conventional manual collecting way is avoided; and the collection of the smoke particles in the environments of some environment simulating experimental devices (such as a hypobaric chamber and a drop tower) and the like, which are not applicable to manual collection, is achieved.

Description

technical field [0001] The invention relates to the technical field of research on smoldering smoke particles of electric wires, and more specifically relates to a collection device for smoldering smoke particles of electric wires. Background technique [0002] Smoldering is the phenomenon of slow burning without flame. It is a form of combustion of solids, which will generate smoke particles during slow combustion, and smoldering can be converted into flaming combustion under certain conditions. [0003] The study of smoke particles produced by smoldering electric wires provides theoretical guidance for improving electrical fire detection technology. However, the research on the smoke particles produced by the smoldering of electric wires first needs to obtain the smoke particles produced by the smoldering electric wires. In order to obtain the smoke particle samples required for research, researchers at home and abroad mostly use manual collection methods. However, in s...
