Description

Technical Field

[0001] This utility model relates to the technical field of gas detection, and in particular to a gas leak detection device. Background Technology

[0002] Natural gas is a common fuel in daily life, making life more convenient. However, accidents caused by gas leaks pose a significant threat to people's lives and property. Liquefied natural gas (LNG) stations and refueling stations require daily inspections during operation. If leaks go undetected for extended periods, large amounts of natural gas can leak and be released, posing a significant safety hazard and causing economic losses to businesses. Existing technology announcement CN219530588U discloses a portable gas leak detection device, comprising: a primary rod, a placement box, a clamping assembly, an olfactory sensor body, and a detection rod. The placement box is movably mounted on the upper left side of the primary rod via a connecting sleeve. However, this device requires the detection rod to be adjusted to a certain height for testing, making it inconvenient to adjust during testing, has a limited detection range, and is relatively inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a gas leak detection device that improves inspection speed, allows for height adjustment during detection, increases the detection range, and enhances practicality.

[0004] This utility model discloses a gas leak detection device, comprising an odor sensor body, two laser methane telemeters, a detection box, a height adjustment component, a support component, a cleaning component, and a rotating component. The odor sensor body is installed inside the detection box, and a processor is located at the bottom of the detection box. A perforated groove is formed on the outer wall of the detection box, and a screen is installed outside the perforated groove. The bottom of the detection box is connected to the top of the height adjustment component, and a support component is installed at the bottom of the height adjustment component. A cleaning component is installed on the top of the detection box. The laser methane telemeters are located below the detection box and are mounted on the rotating component, which is connected to the cleaning component. The support component allows the device to be mounted on a mobile device, improving inspection speed. The height adjustment component allows for easy adjustment of the height of the odor sensor body during detection, enhancing usability. The cleaning component cleans the screen outside the detection box, ensuring detection accuracy. The cleaning component drives the rotating component, enabling the two laser methane telemeters to emit infrared lasers and receive reflected light to measure methane gas in the optical path, increasing the detection range and improving practicality.

[0005] Preferably, the support assembly includes a base, a base box, and connecting plates. The base box is fixedly connected to the bottom of the base, and multiple connecting plates are evenly fixedly installed on the outer wall of the bottom of the base box. The connecting plates have fixing holes. The connecting plates can fix the base box, and the base box and the base support the equipment to ensure stability during use.

[0006] Preferably, the height adjustment assembly includes a vertical pole, an explosion-proof motor, a threaded rod, a support plate, a guide rod, a support slider, a lifting rod, and a second adjustment component. The bottom of the vertical pole is mounted on the top of the base, and a height adjustment cavity is formed inside the vertical pole. An explosion-proof motor is fixedly installed at the bottom of the base, and the output end of the explosion-proof motor is connected to the threaded rod. The threaded rod is rotatably installed in the height adjustment cavity.

The support slider is slidably installed in the guide groove and is connected to the bottom outer wall of the lifting rod. The detection box is located above the top of the lifting rod. When the explosion-proof motor is started, it drives the threaded rod to rotate. The threaded rod pushes the lifting rod to move within the height adjustment chamber, which allows the height of the olfactory sensor to be adjusted at any time during detection, improving the convenience of use. When the threaded rod rotates, it drives the support plate to rotate within the support rotation chamber, reducing the pressure on the explosion-proof motor. When the lifting rod moves, it slides on the guide rod to ensure stability.

[0007] Preferably, the second adjustment component includes a secondary rod, an electric telescopic rod, a telescopic sleeve, and multiple limiting sliders. The secondary rod is fixedly connected to the top of the lifting rod, and an installation cavity is formed inside the secondary rod.

When the forward and reverse motor is started, it drives the conical turntable to rotate, and the conical turntable drives the multiple cleaning frames to rotate. The cleaning brushes scrape and clean the screen outside the detection box, avoiding blockage and improving detection accuracy.

[0009] Preferably, the rotating assembly includes a support ring, a support rotating ring, and a rotating sleeve. The support ring is installed on the outer wall of the telescopic sleeve, and a support rotating groove is opened inside the support ring. The support rotating ring is rotatably installed in the support rotating groove. The rotating sleeve is fixedly installed on the outer wall of the support rotating ring. The top of the rotating sleeve is connected to the bottom of the cleaning frame. Two laser methane telemeters are symmetrically installed on the left and right sides of the rotating sleeve. The forward and reverse motors drive the conical turntable to reciprocate and rotate the lifting rod by 0 degrees. The conical turntable drives the rotating sleeve to rotate through the cleaning frame, thereby adjusting the position of the two laser methane telemeters.
