Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas detection, in particular to an industrial combustible gas detector. Background Art

[0002] Combustible gas refers to substances that can be ignited and are in a gaseous state under normal temperature and pressure. Combustible gas is dangerous and is a dangerous gas that needs to be detected in real time during industrial production. After the combustible gas reaches a certain concentration, it is dangerous and can even cause an explosion. Therefore, it is necessary to detect combustible gas during industrial production. However, the traditional fixed-position installed combustible gas detection device cannot be used after a fire. When a portable combustible gas detector is used for detection, it is necessary to hold it by hand to detect the surrounding air, which is difficult to free the hands; the electric drive increases the gravity of the hand-held device and is difficult to detect through a mechanical drive method; the detection module is easily affected by dust particles after a fire, making it difficult to maintain the accuracy of the detection result. Summary of the Utility Model

[0003] The embodiments of the present disclosure relate to an industrial combustible gas detector. By setting a threaded shaft and a fan blade, the filter cylinder can be driven to move into the fixed brush tube when walking, and the dust on the surface of the filter cylinder can be brushed off by the bristles to ensure cleanliness. The combustible gas in the air is detected by the combustible gas detection module, and the final detection result is wirelessly transmitted to the external mobile terminal, freeing the hands.

[0004] In a first aspect of the present disclosure, there is provided an industrial combustible gas detector, specifically including: a protective housing; the protective housing is of a cylindrical structure, and a fixed brush tube is fixedly connected inside the protective housing, and a threaded shaft is rotationally clamped inside the protective housing; a fan blade is fixedly connected to the threaded shaft; a filter cylinder is threadedly engaged with the threaded shaft inside the fixed brush tube; a combustible gas detection module is arranged inside the filter cylinder and is wirelessly connected to an external mobile terminal.

[0005] In at least some embodiments, a protective cap is fixedly connected to the front end face of the threaded shaft, a receiving groove is formed on the protective cap, a dial is rotationally connected to the inside of the threaded shaft through a shaft, the dial is received inside the receiving groove, and a baffle is fixedly welded to the threaded shaft, and the baffle is located behind the fan blade.

[0006] In at least some embodiments, an inner spring sleeve rod is installed inside the fixed brush tube, the front end of the moving rod of the inner spring sleeve rod is fixedly connected to the rear end face of the filter cylinder, and bristles are fixedly adhered to the inner wall of the fixed brush tube. When the filter cylinder moves to the rear side, the inner spring sleeve rod is compressed, and when the air flow cannot continue to push the filter cylinder to move backward, the spring pushes the filter cylinder to move forward to achieve automatic reset, so that the filter cylinder can move back and forth to ensure the accuracy of the detection result.

[0007] In at least some embodiments, a tapered hole is formed inside the fan blade, and the aperture of the rear side of the tapered hole is smaller than that of the front side. When the user walks with the protective housing, after the air flows into the interior of the protective housing, the fan blade can be driven to rotate like a windmill.

[0008] In at least some embodiments, an annular groove is formed inside the protective housing. The annular groove is located outside the fan blade and is in the same radial plane as the fan blade. The annular groove enables the fan blade to rotate freely, and the air can circulate normally inside the protective housing to ensure the accuracy of combustible gas detection.

[0009] The present utility model provides an industrial combustible gas detector, which has the following beneficial effects:

[0010] When the present utility model is in use, the user walks with the protective housing. The air flowing into the interior of the protective housing drives the fan blade to rotate, coaxially drives the threaded shaft to rotate, and drives the filter cartridge to move into the fixed brush tube through thread engagement. The bristles brush off the dust on the surface of the filter cartridge to ensure cleanliness. The combustible gas detection module detects the combustible gas in the air, and finally the detection result is wirelessly transmitted to the external mobile terminal, liberating the hands.

[0011] When the user walks with the protective housing, after the air flows into the interior of the protective housing, the fan blade can be driven to rotate like a windmill, coaxially drives the threaded shaft to rotate, and the tapered hole can accelerate the air flow speed, making it easier to drive the fan blade to rotate and realizing two power outputs.

[0012] In addition, when using the dial plate, it can be flipped out for use. After turning the dial plate open, the dial plate can be manually rotated to drive the threaded shaft to rotate, and the filter cartridge is driven to move through thread engagement. Without affecting the detection, the air around the detection module can be evenly circulated to ensure the accuracy of the detection result. Description of the Drawings

Brush hairs 402 are fixedly adhered to the inner wall of the fixed brush tube 4. After the filter cartridge 5 moves into the fixed brush tube 4, the brush hairs 402 can brush off the dust on the surface of the filter cartridge 5, thereby ensuring the cleanliness of the wall of the filter cartridge 5 and guaranteeing the detection accuracy. When the filter cartridge 5 moves to the rear side, the inner spring sleeve rod 401 is compressed. When the air flow can no longer push the filter cartridge 5 to move backward, the spring pushes the filter cartridge 5 to move forward to achieve automatic reset, and the filter cartridge 5 can be reciprocally moved to ensure the accuracy of the detection result.

[0031] In the embodiment of the present disclosure, as shown in the attached Figure 2 figure, an annular groove 101 is formed inside the protective housing 1. The annular groove 101 is located outside the fan blade 3 and is in the same radial plane as the fan blade 3. The annular groove 101 enables the fan blade 3 to rotate freely, and normal air circulation can occur inside the protective housing 1 to ensure the accuracy of combustible gas detection.

[0032] In the embodiment of the present disclosure, as shown in the attached Figure 4 figure, a tapered hole 301 is formed inside the fan blade 3. The aperture of the rear side of the tapered hole 301 is smaller than that of the front side.

A storage groove 2011 is formed on the protective cap 201. A dial plate 202 is rotationally connected to the inside of the threaded shaft 2 through a shaft. The dial plate 202 is stored inside the storage groove 2011, and a baffle 203 is fixedly welded to the threaded shaft 2. The baffle is located behind the fan blade 3. The baffle 203 can limit the front side of the filter cartridge 5. The storage groove 2011 is used to store the dial plate 202. When the dial plate 202 is used, it can be flipped out for use. After turning the dial plate 202 away, the dial plate 202 can be manually toggled to drive the threaded shaft 2 to rotate, and the filter cartridge 5 is driven to move through thread engagement, which does not affect the detection and can evenly detect the air around the detection module 501 at the same time.

[0034] Working principle of this embodiment: When the user walks with the protective housing 1, after the air flows through the inside of the protective housing 1, the fan blades 3 can be driven to rotate like a windmill, coaxially driving the threaded shaft 2 to rotate. Through thread engagement, the filter cartridge 5 is driven to move into the fixed brush tube 4, and the bristles 402 can brush off the dust on the surface of the filter cartridge 5, thereby ensuring the cleanliness of the wall of the filter cartridge 5. The combustible gas detection module 501 detects the combustible gas in the air, and finally the detection result is wirelessly transmitted to the external mobile terminal.
