Device for detecting substances in closed space

Abstract

The invention relates to the technical field of closed space detection, and particularly discloses a device for detecting substances in a closed space, comprising an unmanned aerial vehicle, the bottom of the unmanned aerial vehicle body is connected with a transverse plate through a buffer mechanism, the bottom of the transverse plate is rotatably provided with a collection mechanism, and the top of the unmanned aerial vehicle body is provided with a detection mechanism. The ground is drilled through the drill bit, soil drilled by the drill bit can be conveyed upwards through the spiral conveying blade, and the soil drilled by the drill bit is scattered all around under the blocking effect of the connecting disc and the centrifugal force effect of the spiral conveying blade; according to the unmanned aerial vehicle, blocky soil is thrown out by a short distance under the action of heavy gravity and falls onto the ground again, and fine granular soil falls into the collecting box, so that later detection of the soil by workers is facilitated, and meanwhile, the weight of the soil carried by the unmanned aerial vehicle is also reduced.

Description

technical field [0001] The invention relates to the technical field of confined space detection, in particular to a substance detection device in a confined space. Background technique [0002] Confined space is an industrial safety term, which refers to a sealed and closed environment, such as manholes, tunnels and pump rooms, etc.; because access to the site is restricted, and the confined space is usually full of indoor air pollution; from the perspective of fire protection to make a risk assessment, There are huge dangers in confined spaces, including fatal phenomena such as flashback and flashover; therefore, training and assessment are usually required before working in confined spaces. [0003] In the process of mine survey, it is often encountered that there are karst caves in the mountains. The karst caves are naturally formed cavities in the mountains. The interior is a closed space before it is developed. Before entering the karst cave for exploration, it is neces...

Problems solved by technology

[0003] In the process of mine survey, it is often encountered that there are karst caves in the mountains. The karst caves are naturally formed cavities in the mountains. The interior is a closed space before it is developed. Before entering the karst cave for exploration, it is necessary to detect the materials in the karst cave. In order to ensure that the substances in the cave will not cause harm to the human body after human contact, most of them are to detect the air and soil at the opening of the cave, but this detection method is difficult to detect whether there are other harmful substances in the depth of the cave. The detection is not comprehensive enough, so in order to solve such problems, we propose a material detection device in a confined space
