Description

Technical Field

[0001] The present invention relates to the field of gas detection technology, and in particular to an industrial wireless combustible gas detector based on the Internet of Things in underground space. Background Art

[0002] A combustible gas detector is a detector used to monitor the concentration of combustible gas in the air. It can respond differently according to the different concentrations of combustible gas in the air. With the continuous improvement of technology, combustible gas detectors have realized wireless intelligent detection based on the Internet of Things, which has brought great convenience to the use of combustible gas detectors. However, the existing industrial wireless combustible gas detectors based on the Internet of Things still have some problems and defects.

[0003] Combustible gas alarms are usually installed in places where flammable gas may leak. Once the flammable gas leak reaches a certain concentration, an alarm will be sounded to provide a prompt. However, the source of the flammable gas leak is difficult to detect. The reason is that the flammable gas detectors usually installed are fixed and cannot be moved. Therefore, the alarm can only be sounded when the flammable gas leaks around the detector, which often delays the alarm time, easily leads to safety hazards, and even causes accidents.

[0004] Therefore, we made improvements to this and proposed an industrial wireless combustible gas detector based on the Internet of Things in underground space. Summary of the Invention

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] like Figures 1-9 As shown, this embodiment proposes an industrial wireless combustible gas detector based on the Internet of Things in underground space, including a detector body 1, a detection mechanism 2 installed at the bottom of the detector body 1, and a connector 3 installed on the back of the detector body 1. The back of the detector body 1 is connected with a guide rail 4, and the guide rail 4 includes a straight rail 42 and two extension plates 43 sleeved on both ends of the straight rail 42. The middle of the extension plate 43 is also movably connected with a sliding component 41, and the sliding component 41 is bolted to the connector 3. The end of the extension plate 43 is connected with a swing mechanism 5, and the outer end of the swing mechanism 5 is movably installed with a walking mechanism 6. The two walking mechanisms 6 at both ends of the guide rail 4 are pressed parallel to the walls on both sides of the building.

[0032] The detection mechanism 2 includes a filter cartridge 21, the upper end of the filter cartridge 21 is threadedly connected to the sensor part of the detector body 1, and a dustproof cartridge 22 is sleeved on the outer side of the filter cartridge 21. A brush 23 is provided on the inner side of the dustproof cartridge 22, and the brush 23 is in contact with the surface of the filter cartridge 21. The filter cartridge 21 and the dustproof cartridge 22 are self-cleaned during the sliding process along the guide rail 4 to avoid dust accumulation at the air inlet of the sensor, resulting in blockage and aging, resulting in false alarms and missed alarms.

[0033] The sliding assembly 41 includes a connecting plate 411, on which a rotating first gear 412 is sleeved, and a clamping block 414 is fixedly connected to the outer end of the first gear 412, and a connecting frame 415 is installed in the middle of the clamping block 414, and the clamping block 414 and the connecting frame 415 are connected to the straight rail 42. A gear motor 413 is also provided at the bottom of the connecting plate 411, and the gear motor 413 is meshed and connected to the first gear 412. The sliding assembly 41 is used to connect with the connecting member 3 to facilitate the installation and fixation of the detector body 1. At the same time, by installing a clamping block 414 that slides with the straight rail 42 on the connecting plate 411, and the clamping block 414 is meshed with the gear motor 413 through the first gear 412, it is convenient to drive the detector body 1 and the connecting plate 411 to rotate along the first gear 412 through the gear motor 413 to adjust the detection angle of the detector body 1.

[0034] The straight rail 42 includes a square cabinet 421, which has a groove facing the side of the sliding component 41. The interior of the square cabinet 421 is connected to a slide rod 422, and the block 414 is socketed with the slide rod 422. A tooth plate 423 is also installed at the bottom of the square cabinet 421, and a rack is provided on the edge of the tooth plate 423. The slide rod 422 installed on the straight rail 42 is socketed with the sliding component 41, which facilitates the limited sliding of the sliding component 41 along the straight rail 42, ensuring the smooth use of the detector body 1 and the guide rail 4.

[0035] The extension plate 43 includes a sleeve 431, which is semi-enclosed and sleeved on the outside of the straight rail 42. An electric push rod 432 is connected between the side wall of the sleeve 431 and the straight rail 42. A connecting ring 433 is installed on the outer end of the sleeve 431. The extension plate 43 is installed on both sides of the straight rail 42. The overall width of the guide rail 4 is adjusted by connecting the electric push rod 432 to the straight rail 42, so that the two ends of the guide rail 4 can be pressed against the walls on both sides.

[0036] The upper end of the dustproof cylinder 22 is provided with a circle of convex teeth 24, which are engaged with the tooth plate 423. The straight rail 42 rotates along the tooth plate 423, driving the filter cartridge 21 and the dustproof cylinder 22 to complete self-cleaning, preventing dust accumulation at the air inlet of the sensor from causing blockage and aging, resulting in false alarms and missed alarms.

[0037] The rocking mechanism 5 includes a turntable 51, the inner side surface of the turntable 51 is eccentrically connected to a rotating joint 54, and a connecting sleeve 52 is rotatably connected to the rotating joint 54. The connecting sleeve 52 is hinged to the extension plate 43, and a second gear 53 is centrally installed on the outer side surface of the turntable 51. The turntable 51 is sleeved on the traveling mechanism 6, and the second gear 53 is engaged with the third gear 62. The rotating joint 54 is rotatably connected to the connecting sleeve 52, and the connecting sleeve 52 is hinged to the guide rail 4, connecting the guide rail 4, the rocking mechanism 5, and the traveling mechanism 6 to facilitate large-scale detection of the device.

[0038] The walking mechanism 6 includes a bracket 61, and two third gears 62 are installed inside the bracket 61. The outer ends of the two third gears 62 are fixedly connected to self-driven rollers 63, and the upper end of one of the self-driven rollers 63 is connected to a driving motor. The middle of the bracket 61 is fixedly connected to a mounting frame 64, and an electric suction cup 65 is fixedly installed on the mounting frame 64. The self-driven roller 63 is driven to rotate, so that the device moves parallel to the wall. The electric suction cup 65 is adsorbed on the wall to increase the connection strength between the wall and the device and prevent the device from detaching. At the same time, the self-driven roller 63 is engaged with the swing mechanism 5 through the third gear 62, and drives the swing mechanism 5 and the guide rail 4 to move while the device is walking, so as to realize the left and right sliding of the detector body 1.

[0039] The eccentric positions of the rotating joints 54 installed on the two swing mechanisms 5 are opposite to each other in the upper and lower parts. Through the connection between the two rotating joints 54 and the guide rail 4, the swing mechanism 5 rotates intermittently with a period of 180 degrees, so that the two connecting sleeves 52 connected to the two ends of the guide rail 4 rotate in opposite directions, so that the guide rail 4 maintains a posture tilted to the left or right when it is in a paused state. The guide rail 4 slides from the high end to the low end on the straight rail 42 along with the sliding component 41, and a large-scale monitoring of places where combustible gas escapes is carried out, thereby improving the detection accuracy of the device.

[0040] Specifically, when the present industrial wireless combustible gas detector based on the Internet of Things in underground space is in use: the detector body 1 is connected and installed on the guide rail 4 through the connecting piece 3, the extension plates 43 at both ends of the straight rail 42 are stretched to both sides and pressed against the walls on both sides, so that the device is clamped in the middle of the walls on both sides, and the movable walking mechanism 6 drives the detector body 1 and the guide rail 4 to move horizontally along the wall, and the wall is adsorbed and fixed by the electric suction cup 65 to prevent the device from falling off, and in the process of rolling of the walking mechanism 6, the third gear 62 is engaged with the second gear 53, driving the swing mechanism 5 to rotate intermittently with a cycle of 180 degrees, and the rotating joint 54 eccentrically installed on the inner side of the turntable 51 is rollingly connected with the connecting sleeve 52, and the two rotating joints 54 rotate with the rotation of the turntable 51, so that the two connecting sleeves 52 connected to the two ends of the guide rail 4 rotate in opposite directions, so that the guide rail 4 maintains a tilted posture to the left or right when it is stopped, and along the tilt angle of the guide rail 4, the detector body 1 moves from a high position on the straight rail 42 along with the sliding component 41. The detector body 1 is provided with a toothed plate 423 at the bottom, and a filter cartridge 21 is provided at the outside of the sensor at the bottom of the detector body 1. The filter cartridge 21 is used to prevent dust and dirt. A dustproof cartridge 22 is sleeved on the outside of the filter cartridge 21. The upper end of the dustproof cartridge 22 is provided with a convex tooth 24, which is engaged with the toothed plate 423, so that when the detector body 1 slides on the inclined guide rail 4, the toothed plate 423 drives the convex tooth 24 to rotate, so that the brush 23 provided between the dustproof cartridge 22 and the filter cartridge 21 cleans the surface of the filter cartridge 21, thereby avoiding the problem of false alarms and missed alarms caused by dust accumulation at the air inlet of the sensor, resulting in blockage and aging. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

[0041] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be encompassed by the scope of the claims of the present invention.
