Test device and method for detecting smoke alarm

Abstract

The invention discloses a test device and method for detecting a smoke alarm. The test device comprises a telescopic rod and a smoke generating part located at the front end of the telescopic rod, wherein the interior of the telescopic rod is a hollow cavity; the smoke generating part is composed of a bearing seat, a tray and a smoke source; a concave pit is formed in the upper end face of the tray, and a smoke source is arranged in the concave pit; a plurality of through holes are formed in the side edge of the bearing seat, and the through holes are communicated with the cavity of the telescopic rod; hollow guide rods are further arranged in the through holes; a vacuum suction disc is arranged at the top end of each hollow guide rod; and a pull rope sequentially penetrates through the hollow guide rods, the through holes and the cavity to extend to the tail end of the telescopic rod to be fixed. According to the device, the smoke source is simulated, the smoke alarm is more accurately tested through the structure supported by the tray, and the practical simulation requirement can be almost met. Meanwhile, the vacuum suction disc is utilized, so that the stability of the device isincreased, and the problem that the simulated smoke source is not flowing regularly is solved; and the whole structure adopts an insulating material, so that the safety of a human body and a chargingdevice is ensured, and the test device is a time-saving and labor-saving and high-efficiency test device for detecting the smoke alarm.

Description

technical field [0001] The invention relates to a smoke detection device, in particular to a test device and method for detecting a smoke alarm. Background technique [0002] The smoke detector realizes fire prevention by monitoring the concentration of smoke. The internal use of ionic smoke sensor is widely used in power distribution room for fire prevention. The smoke detector is hung on the ceiling all the year round, and it is prone to failure in the past. Therefore, it is necessary to perform analog alarm detection on a regular basis. The installation height of the existing power distribution room workshop is as high as 6 meters, and it is difficult for inspection personnel to hold an external smoke source to simulate the smoke alarm; some use a smoke gun to be close to the smoke alarm, but the smoke gun is too long to hold The tester is unstable, and it is easy to hit the live equipment, which poses a safety hazard; the hand-held smoke source is unstable, so the detec...
