Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gas management detection, specifically to a coal mine underground gas management detection device. BACKGROUND

[0002] Gas is a flammable and explosive, colorless and odorless gas, which determines the danger of gas in the process of coal mine production. Gas explosion is one of the most important safety hazards in coal mine. Prevention and control of gas can greatly reduce the occurrence of gas explosion accidents and protect the safety of miners. Therefore, during the construction process in the coal mine, the content of gas needs to be detected in time, and the gas needs to be removed by keeping ventilation.

[0003] Patent No. CN 221351383 U discloses a coal mine underground gas management detection device. The detector is installed inside the space formed by the installation frame, two fairings, two dust screen installation frames and two dust screens, and the gas in the coal mine can enter the inside of the installation frame and be detected by the fan. This avoids exposing the detector to the outside environment and avoids the influence of dust on the detector, ensuring the service life of the detector. The connection block, connection slot and mounting plate make it easy to install and remove the dust screen. When the dust screen is covered with a lot of dust, it can be easily removed and cleaned. The cooperation of the lifting structure, adjustment hole, adjustment bolt, support rod, lifting rod and lifting ring can adjust the height of the guide wheel, so that the coal mine underground gas management detection device can perform a wider range of detection operations, further improving the detection range of the coal mine underground gas management detection device and improving the practicality and structural flexibility of the coal mine underground gas management detection device.

[0004] However, in use, it has the following defects:

[0005] Although the detector is installed inside the installation frame and the dust screen is used for dust treatment, the device loses its dustproof ability when the dust screen is removed for cleaning, allowing dust from the outside to enter. Moreover, the device can only perform air extraction detection in one direction, with a limited range and low detection efficiency. UTILITY MODEL CONTENTS

[0008] In this technical scheme, two air inlets are arranged in four directions of the isolation cylinder, so that air suction and detection can be carried out in four directions, thereby increasing the range of air suction and detection and improving the detection efficiency. During use, the baffle blocks one air inlet, and when the dust filter element in the other air inlet needs to be replaced or cleaned, the rotary table is rotated to move the baffle to the other air inlet, thereby allowing normal replacement and cleaning of the dust filter element. In addition, normal air suction and detection can be carried out during replacement, and dust entering is minimized, thereby improving dust prevention and detection efficiency.
