Embodiment Construction

[0034] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as Figure 1-12 As shown, a combustible gas concentration detection probe includes a probe body 1, a probe cover 2, a connecting body 3 and an upper joint 4; the probe body 1, the connecting body 3 and the upper joint 4 are all cylindrical, arranged from bottom to top, The upper part of the probe body 1 is connected to the upper joint 4 through the connecting body 3 . The probe body 1 and the connecting body 3, the connecting body 3 and the upper joint 4 are all threaded.

[0036] Such as figure 1 , 2 , 7, the probe cover 2 is an arc-shaped cover, which is placed outside the probe body 1, and the bottom end of the probe cover 2 is higher than the bottom end of the probe body 1;

[0037] Such as Figure 5-6 As shown, the upper center of the probe body 1 is provided with an upper groove 6, and the side wall of the u...

Abstract

The invention provides a combustible gas concentration detection probe. The combustible gas concentration detection probe comprises a probe body, a probe outer cover, a connector and an upper connector, wherein the probe body, the connector and an upper connector are arranged from bottom to top; the upper part of the probe body is connected with the upper connector through the connector. The probeouter cover is an arc-shaped outer cover and sleeves the outer part of the probe body; the bottom end of the probe outer cover is higher than the bottom end of the probe body; an upper groove is formed in the center of the upper part of the probe body; a plurality of inclined through holes which are inclined downward are formed in a side wall of the upper groove; openings of the inclined throughholes in the probe body are located at the upper part of the probe body. External gas enters a gas sensor through a gas channel formed by the probe; when the probe is placed in water, gas seal can beformed between the upper part of the probe and the outer cover and is used for preventing water from entering the probe; the probe can be used for detecting the gas in a pipeline well; the water levelheight in the pipeline well exceeds the probe, the water cannot enter a detection element and the detection element is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of combustible gas detection, in particular to a combustible gas concentration detection probe. Background technique [0002] Combustible gas detection and alarm devices are widely used in petroleum, gas, chemical, oil depots and other petrochemical industries where toxic gases exist, and can detect leakage in indoor and outdoor and dangerous places in pipelines. [0003] In the prior art, there are many combustible gas detection and alarm devices, but because the internal circuit boards and gas sensors (such as methane concentration sensors) cannot enter water, combustible gas detection and alarm devices generally cannot be used in places with water. occasion. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the present invention provides a combustible gas concentration detection probe. The gas sensor is placed in the cavity inside the probe, and connected to the...
