Embodiment 1

[0038] Such as figure 1 , figure 2 As shown, the spark detection probe performance testing device is equipped with a thermal radiation source 2, an optical component and a clamping device from left to right. The optical assembly includes a light shielding part, a distance attenuator 4 and an aperture 5 . The probe 6 to be tested is clamped on the clamping device.

[0039] The device can detect various types of spark detection probes. According to different types of probes 6 to be tested, different heat radiation sources 2 can also be selected, such as blackbody radiation sources, resistance wires, gas welding torches, and the like.

[0040] As the propagation distance increases, thermal radiation will naturally attenuate. The distance attenuator 4 is used to attenuate heat radiation, so that the overall footprint of the device is small, and the resulting heat signal is weakened within a relatively short distance. The distance attenuator 4 can be of optical fiber type, suc...

Embodiment 2

[0053] Like Embodiment 1, the belt 3 is a net-like or frame-like structure, on which a base is detachably connected. The connection method can be bonding, clamping and the like.

[0054] In this way, various types of light-transmitting regions can be replaced without changing the belt 3 . The material of the substrate can be selected from heat-resistant materials, and cooling devices can be arranged at other positions of the light-shielding part for cooling the belt 3 . For example, a cooling device is installed at pulley 1.

Embodiment 3

[0056] Such as Figure 3 to Figure 6 As shown, the style of the light transmission area can be selected and adjusted according to the actual performance to be measured, such as the porous first light transmission area 3a, the circular hole-shaped second light transmission area 3b, the rectangular third light transmission area 3c, The elliptical fourth light-transmitting region 3d.

Abstract

The invention relates to a method for testing the performance of a spark detection probe, which comprises: a heat source device, an optical component and a clamping device arranged in sequence; the heat source device is used to generate heat radiation, and the heat radiation propagates toward the clamping device; the optical component is located at In the thermal radiation propagation path, the thermal radiation is used to form different types of thermal radiation signals; the clamping device is used to clamp the spark detection probe to be detected. The spark detection probe performance testing device provided by the present invention can flexibly and accurately detect the response time, sensitivity and other properties of the spark detection probe. It is suitable for different spark detection probes and suitable for different working conditions.

Description

technical field [0001] The invention relates to the field of equipment testing devices, in particular to a performance testing device and method for a spark detection probe, and also to a performance testing device for a spark detection and extinguishing system. Background technique [0002] In recent years, incalculable economic losses have been caused due to the tiny sparks generated in the industrial production process being transmitted to the dust removal system through pipelines and causing explosions. In order to reduce the occurrence of the above problems, the application of spark detection and extinguishing system was born. The performance of spark detection and extinguishing systems sold on the market is uneven, and there are even some inferior spark detection and extinguishing devices. The invention provides a device that can be used to detect the overall response time of the spark detection and extinguishing system and the performance test of the probe. The devic...
