Description

Technical Field

[0001] The present invention relates to the field of gas alarms, and in particular to an Internet of Things gas intelligent alarm. Background Art

[0002] A gas alarm is a gas leak detection alarm instrument. When gas leaks in an industrial environment and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas alarm will send out an alarm signal. A gas leak detector is a detector that detects gas concentration. Its core component is a gas sensitive sensor, which is installed in places where gas leaks may occur. Gas alarms are mostly used for household gas leak alarms, and are also widely used in various refineries, oil depots, chemical plants, liquefied gas stations and other places where combustible gas leaks are prone to occur.

[0003] However, existing gas alarms mainly rely on the passive detection principle, that is, they rely on the natural flow of air to allow it to pass through the alarm on its own. Under this mechanism, the sensor equipped on the alarm is responsible for analyzing the composition of the air flowing through it to detect whether there is a gas leak. Its response speed is limited by the natural rate of air flow, and it is often unable to capture gas leaks quickly, resulting in alarm delays, which is not conducive to early detection and handling of safety hazards. In addition, when the alarm finally detects a gas leak, its function is limited to issuing an alarm signal to alert the operator to pay attention and take action. Although this single alarm function can arouse people's vigilance, it lacks direct response measures or intervention mechanisms to actively reduce the gas concentration in the air, thereby failing to effectively control the development of the situation and reduce potential explosion or poisoning risks.

A second traction arm 22 is fixedly provided at one end of the second rack 28, and an end of the second traction arm 22 away from the second rack 28 is fixedly connected to the inner wall of the adjustment housing 12. In order to increase the stability of the first traction arm 19 and the second traction arm 22, one end of the first traction arm 19 and then the second traction arm 22 is movably sleeved on the periphery of the fixing frame 21. Further, the inner wall of the lower housing 3 is provided with a second guide groove 47 parallel to the axis of the lower housing 3, and the end of the second guide groove 47 away from the upper housing 1 is provided with The third guide groove 48 is spiral, and the inner walls of the second guide groove 47 and the third guide groove 48 have a smooth transition. The outer side of the adjustment housing 12 is fixedly provided with a second guide block 49 that is movably guided and matched with the second guide groove 47 and the third guide groove 48. Further, the end of the adjustment housing 12 away from the upper housing 1 is provided with a first bottom plate 7, and the first bottom plate 7 is evenly surrounded by a fan-shaped second air inlet groove 8. The first bottom plate 7 is rotatably connected to the side of the upper housing 1 close to the first bottom plate 7, and the second bottom plate 11 is connected to the first bottom plate 7. The second bottom plate 11 is provided with a fan-shaped second air inlet groove 8. The second air inlet groove 8 corresponds to the fourth air inlet groove 52 which is fan-shaped. The second base plate 11 is provided with a plurality of limiting rods 46 corresponding to the fixing frame 21 at one end close to the upper shell body 1. The fixing frame 21 is provided with a receiving hole 30 corresponding to and adapted to the limiting rods 46 at one end close to the second base plate 11. The limiting rod 46 is movably connected to the inner side of the receiving hole 30 at one end away from the second base plate 11. In order to reduce dust impurities in the incoming air, filters for filtering dust are provided in the first air inlet groove 5, the fourth air inlet groove 52, the third air inlet groove 51 and the second air inlet groove 8.

[0050] Working principle: when in use, the activated carbon filter plate 14 and the exhaust groove 4 are in a staggered state, and the adjustment shell 12 is hidden on the inner side of the lower shell 3. At this time, the second guide block 49 is located at the end of the second guide groove 47 away from the third guide groove 48, and at this time, the second air inlet groove 8 and the fourth air inlet groove 52 partially overlap. During use, the second driving source 24 drives the turntable 31 to rotate, and the turntable 31 drives the fan blades 32 to rotate. The first elastic member 40 and the second elastic member 44 are in a reset state, and the inclination angle of the fan blades 32 is small. When the fan blades 32 rotate, negative pressure is generated, and the outside air can quickly enter through the first air inlet groove 5 and the second air inlet groove 8, and then be discharged from the exhaust groove 4 under the guidance of the guide plate 17 after being detected by the gas detection sensor 18. When gas is detected, the first driving source 23 can be automatically controlled to operate under the action of the controller 16, and the first driving source 23 drives the screw rod 25 to rotate, and the screw rod 25 drives the lifting frame 26 to move toward the direction of the gas detection sensor 18, and the lifting frame 26 is lifted. The frame 26 drives the driving rod 50 to enter the turntable 31, and then the driving rod 50 pushes the column 38, the adjustment frame 35, and the adjustment rod 37 to move as a whole, and the guide rod 39 guides, and the first elastic member 40 will shrink. Since the adjustment rod 37 and the adjustment hole 45 are both inclined, the adjustment rod 37 will expand and move outward, the telescopic rod 43 guides, and the second elastic member 44 is compressed. At the same time, the adjustment shaft 36 is driven to move by the adjustment seat 34. Under the action of the first guide block 42 and the first guide groove 41, the rotating shaft 33 and the fan blade 32 rotate as a whole, and then the inclination angle of the fan blade 32 increases, thereby increasing the exhaust effect. In addition, when the lifting frame 26 moves, it will also drive the first traction arm 19 to move. The first traction arm 19 will drive the activated carbon filter plate 14 to approach the exhaust groove 4, and then cover the exhaust groove 4. At this time, the gas entering will be filtered by the activated carbon filter plate 14 and then discharged from the exhaust groove 4, thereby reducing the gas concentration and reducing safety hazards.

[0051] In order to adapt to the increase in the inclination angle of the fan blade 32, the lifting frame 26 will also drive the first rack 27 to move when it moves. Under the action of the gear 29, the second rack 28 moves in the opposite direction, and then the second rack 28 drives the adjustment shell 12 to extend from one end of the lower shell 3 through the second traction arm 22, and then the third air inlet groove 51 on the adjustment shell 12 extends. After extending a certain distance, the second guide block 49 enters the third guide groove 48, so that the adjustment shell 12 will rotate subsequently. After the rotation, the third air inlet groove 51 is staggered with the first air inlet groove 5, so that air can be pumped in different directions, thereby improving the air pumping effect;

[0052] Furthermore, in order to further increase the air intake, the displacement of the adjusting housing 12 will drive the first bottom plate 7 and the second bottom plate 11 to move synchronously. When the adjusting housing 12 and the lower housing 3 rotate relative to each other, due to the cooperation of the limiting rod 46 and the accommodating hole 30, the first bottom plate 7 and the second bottom plate 11 rotate relative to each other, thereby reducing the overlapping area of ​​the fourth air inlet groove 52 and the second air inlet groove 8, thereby increasing the amount of gas entering the second air inlet groove 8, thereby achieving the best air extraction effect.

[0053] After the potential safety hazard is eliminated, the inclination angle of the adjusting shell 12 is reduced, and the activated carbon filter plate 14 and the adjusting shell 12 are hidden again. The activated carbon filter plate 14 is hidden to prevent fine dust from passing through the activated carbon filter plate 14 when there is no gas leakage, causing rapid saturation of the activated carbon filter plate 14, thereby ensuring that the activated carbon filter plate 14 is only used to filter gas.

[0054] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
