Detection device for detecting harmful gas in smart pipe gallery

Abstract

The invention relates to a detection device for detecting a harmful gas in a smart pipe gallery. The detection device comprises a base and at least two moving wheels, and also comprises a displacementmechanism and a detection mechanism, wherein the displacement mechanism comprises a first driving component, a steering component, an air cylinder, two first drive rods, two second drive rods and twofirst slide blocks; the first driving component comprises a driving unit, a supporting rod, a drive unit and two third drive rods; the detection mechanism comprises a shell, a piston, an air inlet, an air outlet, a gas sensor, a supporting frame, a second driving component and a first driving rod. In the detection device for detecting the harmful gas in the smart pipe gallery, through the displacement mechanism, the position regulation of the detection mechanism is realized; thus, a detection range of the detection mechanism is expanded; the accuracy of the detection device is improved; the detection of the harmful gas is carried out on a proper amount of air sample through the detection mechanism; an influence, on a detection result, of an air mass flow is decreased, and the precision ofa detection apparatus is improved.

Description

technical field [0001] The invention relates to the field of detection equipment for a smart pipe gallery, in particular to a detection device for detecting harmful gases in a smart pipe gallery. Background technique [0002] The smart pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure to ensure the operation of the city. [0003] Because the smart pipe gallery is in a sealed state for a long time, harmful gas will be generated inside the smart pipe gallery. Generally, the harmful gas detection device is fixed in one place of the smart pipe gallery. Due to the poor air flow inside the smar...

Problems solved by technology

[0003] Because the smart pipe gallery is in a sealed state for a long time, harmful gas will be generated inside the smart pipe gallery. Generally, the harmful gas detection device is fixed in one place of the smart pipe gallery. Due to the poor air flow inside the smart pipe gallery, the detection device is reduced. The accuracy of the detection results is not only that, but the sensors of the general detection device are directly in contact with the air. During the detection process, the air flow will have a greater impact on the detection results, thereby reducing the accuracy of the detection device.
