Spark detecting device with self-cleaning effect

Abstract

The invention discloses a spark detecting device with a self-cleaning effect. The spark detecting device comprises an outer casing, an inner casing, a detector body, an ultraviolet photodiode, an infrared photodiode, inner glass and outer glass, wherein the inner casing is fixedly disposed in the inner cavity of the outer casing; a protective layer is fixedly disposed between the outer casing andthe inner casing; the detector body is fixedly disposed in the inner cavity of the inner casing; the ultraviolet photodiode is fixedly disposed on a side of the surface of the detector body; and the infrared photodiode is fixedly disposed on the bottom of the ultraviolet photodiode; the inner glass is fixedly disposed on one side surface of the inner casing; the outer glass is fixedly disposed onone side surface of the outer casing; and a fan is fixedly disposed on the top surface of the outer casing. The outer glass of the spark detecting device can be cleaned by the fan and a ventilation head, and is further cleaned by a movable rod and a brush so that the normal operation of the spark detecting device is guaranteed.

Description

technical field [0001] The invention relates to a spark detection device, in particular to a spark detection device with self-cleaning effect. Background technique [0002] In order to cause a fire accident in the factory, a spark alarm device, that is, a spark detector, must be installed in the process flow. However, during the actual use of the Mars probe, due to the different working environments, the air contains dust, impurities, etc. With the increase of dust, impurities or short fibers and other light-blocking deposits, the light transmittance of the lens of the spark probe will gradually decrease. The drop will directly affect the detection effect of the spark probe. In severe cases, even if the raw material contains sparks, the spark probe cannot detect it. The spark detector cannot isolate the raw materials containing sparks in time. In this case, there is a risk of fire accidents. Reduce the occurrence of fire accidents. To this end, we propose a spark detection...
