Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically a biogas concentration alarm device. Background Technology

[0002] Biogas is a mixed gas produced by the fermentation of organic matter under anaerobic conditions by microorganisms. Currently, safety accidents during biogas use mainly manifest as poisoning, combustion, and explosion. Leakage is a relatively common problem in biogas projects. Biogas leaks are not easily detected in time, and if they come into contact with an open flame, they can easily cause fires, explosions, or other ignitions. Therefore, it is necessary to monitor biogas concentration using biogas concentration alarms.

[0003] Currently, conventional biogas concentration alarm devices cannot detect the gas itself during use. They can only detect it when the biogas drifts directly to the device, resulting in poor monitoring performance. Furthermore, dust, water vapor, and insects can contaminate the sensors, leading to inaccurate detection results. Additionally, prolonged exposure to high temperatures can damage electrical components within the internal control components of biogas concentration alarm devices, reducing their lifespan. Therefore, we have proposed a biogas concentration alarm device to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a biogas concentration alarm device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A biogas concentration alarm device includes a rectangular box. A control component and a sensor component are mounted on the rear inner wall of the rectangular box. A buffer mechanism is installed on the lower side wall of the rectangular box corresponding to the sensor component. A miniature vortex fan is fixedly mounted on the upper surface of the buffer mechanism. An air intake mechanism is fixedly mounted on the lower surface of the buffer mechanism corresponding to the miniature vortex fan, and the air intake mechanism extends movably beyond the lower side wall of the rectangular box. Exhaust mechanisms are located near the upper sides of the left and right side walls of the rectangular box. An inlet pipe is installed near the lower side of the left side wall of the rectangular box. An alarm is installed on the upper side wall of the rectangular box. A sealing cover is threaded onto the front side wall of the rectangular box, and a display screen is fixedly embedded in the middle of the front side wall of the sealing cover.

[0007] Furthermore, the four corners of the rear side wall of the rectangular box are provided with rectangular mounting holes.

[0008] Furthermore, the buffer mechanism includes a spring-damped shock absorber and a mounting plate. The spring-damped shock absorber is rectangularly and fixedly installed on the lower inner wall of the rectangular box, and the mounting plate is fixedly installed between the upper surfaces of the spring-damped shock absorber.

[0009] Furthermore, the air intake mechanism includes a circular sleeve, a stainless steel grille, a first waterproof and breathable membrane, and a ceramic honeycomb panel. The circular sleeve is fixedly embedded in the mounting plate, and both the upper and lower sides of the circular sleeve are open structures. The stainless steel grille, the first waterproof and breathable membrane, and the ceramic honeycomb panel are fixedly installed from bottom to top on the inner wall of the circular sleeve near the lower side.

[0010] Furthermore, a rubber sealing ring is installed on the lower side wall of the rectangular box corresponding to the circular sleeve.

[0011] Furthermore, the exhaust mechanism includes a metal filter and a second waterproof and breathable membrane. The metal filter is fixedly embedded in the side wall of the rectangular box, and the second waterproof and breathable membrane is fixedly pasted on the inner wall of the rectangular box corresponding to the metal filter.

[0012] Furthermore, a transparent protective cover is threaded onto the front side of the sealing cover.

[0013] Compared with the prior art, the present invention provides a biogas concentration alarm device, which has the following beneficial effects:

[0014] This invention enhances the intake function of the biogas concentration alarm device by combining a miniature vortex fan with an air intake mechanism, enabling faster detection of biogas concentration. The air intake mechanism filters dust, water vapor, and corrosive substances from the incoming gas, preventing damage to the sensor components and ensuring accurate detection. Furthermore, the air intake mechanism is less prone to clogging, while the exhaust mechanism removes high-temperature components from the biogas concentration alarm device, improving heat dissipation and preventing damage to internal electrical components due to overheating, thus facilitating its use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figures 1-4 As shown, an embodiment of the biogas concentration alarm device of this utility model includes a rectangular box 1. A control component 2 and a sensor component 3 are provided on the rear inner wall of the rectangular box 1. A buffer mechanism 4 is installed on the lower side wall of the rectangular box 1 corresponding to the sensor component 3. A miniature vortex fan 5 is fixedly installed on the upper surface of the buffer mechanism 4. An air intake mechanism 6 is fixedly installed on the lower surface of the buffer mechanism 4 corresponding to the miniature vortex fan 5, and the air intake mechanism 6 extends movably out of the lower side wall of the rectangular box 1. An exhaust mechanism 7 is provided on the left and right side walls of the rectangular box 1 near the upper side. An inlet pipe 8 is installed on the left side wall of the rectangular box 1 near the lower side. An alarm 9 is installed on the upper side wall of the rectangular box 1. A sealing cover 10 is threadedly installed on the front side wall of the rectangular box 1. A display screen 11 is fixedly embedded in the middle of the front side wall of the sealing cover 10.

[0022] like Figure 1 and Figure 2 As shown, in some embodiments, the four corners of the rear sidewall of the rectangular box 1 are provided with rectangular mounting holes 12.

[0023] In this embodiment, the mounting hole 12 facilitates the fastening of bolts to fix the rectangular box 1, which makes it convenient to install the biogas concentration alarm device.

[0024] like Figure 2 and Figure 3As shown, in some embodiments, the buffer mechanism 4 includes a spring damping shock absorber 401 and a mounting plate 402. The spring damping shock absorber 401 is rectangularly and fixedly installed on the lower inner wall of the rectangular box 1, and the mounting plate 402 is fixedly installed between the upper surfaces of the spring damping shock absorber 401.

[0025] In this embodiment, the spring damping shock absorber 401 is installed on the mounting plate 402, and at the same time, the buffering and shock absorption function of the mounting plate 402 is increased, so that the vibration generated by the micro vortex fan 5 will not be transmitted to the rectangular box 1.

[0026] like Figure 4 As shown, in some embodiments, the air intake mechanism 6 includes a circular sleeve 601, a stainless steel grille 602, a first waterproof and breathable membrane 603, and a ceramic honeycomb panel 604. The circular sleeve 601 is fixedly embedded in the mounting plate 402, and both the upper and lower sides of the circular sleeve 601 are open structures. The stainless steel grille 602, the first waterproof and breathable membrane 603, and the ceramic honeycomb panel 604 are fixedly installed from bottom to top on the inner wall of the circular sleeve 601 near the lower side.

[0027] In this embodiment, the circular sleeve 601 allows external gas to be drawn into the rectangular box 1 by the micro vortex fan 5, and the gas is filtered by the stainless steel grid 602, the first waterproof and breathable membrane 603 and the ceramic honeycomb plate 604 to remove impurities, dust, insects, water vapor and corrosive substances.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, a rubber sealing ring 13 is installed on the lower side wall of the rectangular box 1 corresponding to the circular sleeve 601.

[0029] In this embodiment, the rubber sealing ring 13 enhances the sealing effect between the circular sleeve 601 and the lower side wall of the rectangular box 1, and also accommodates the small-amplitude vibration of the circular sleeve 601.

[0030] like Figure 2 As shown, in some embodiments, the exhaust mechanism 7 includes a metal filter 701 and a second waterproof and breathable membrane 702. The metal filter 701 is fixedly embedded in the side wall of the rectangular box 1, and the second waterproof and breathable membrane 702 is fixedly pasted on the inner wall of the rectangular box 1 corresponding to the metal filter 701.

[0031] In this embodiment, the metal filter 701 and the second waterproof and breathable membrane 702 prevent external dust and moisture from entering the rectangular box 1 and allow the high-temperature gas inside the rectangular box 1 to be discharged.

[0032] like Figure 3 As shown, in some embodiments, a transparent protective cover 14 is threaded onto the front side of the sealing cover 10.

[0033] In this embodiment, the transparent protective cover 14 increases the protection function of the display screen 11, making the display screen 11 less prone to damage.

[0034] In use, the rectangular box 1 is installed in the desired location by fastening the bolts through the mounting holes 12 on it. The micro vortex fan 5 then draws air from the intake mechanism 6. The circular sleeve 601 allows external gas to be drawn into the rectangular box 1 by the micro vortex fan 5. Impurities, dust, insects, water vapor, and corrosive substances in the incoming gas are filtered through the stainless steel grille 602, the first waterproof and breathable membrane 603, and the ceramic honeycomb plate 604, enhancing the intake function of the biogas concentration alarm device. Biogas quickly enters the sensor assembly 3 inside the rectangular box 1, enabling faster detection of biogas concentration and preventing damage to the sensor assembly 3, ensuring accurate detection. Simultaneously, the spring damping shock absorber 401 in the buffer mechanism 4 ensures... The mounting plate 402 can vibrate. When the micro vortex fan 5 draws air, it vibrates, causing the micro vortex fan 5 to drive the circular sleeve 601 to vibrate via the mounting plate 402. The circular sleeve 601 drives the stainless steel grille 602, the first waterproof and breathable membrane 603, and the ceramic honeycomb plate 604 to vibrate. This makes the stainless steel grille 602, the first waterproof and breathable membrane 603, and the ceramic honeycomb plate 604 less prone to contamination, and prevents the air intake mechanism 6 from becoming clogged. The micro vortex fan 5 blows air into the rectangular box 1, causing the high-temperature gas inside the rectangular box 1 to be discharged to the outside of the rectangular box 1 through the metal filter 701 and the second waterproof and breathable membrane 702 in the exhaust mechanism 7. At the same time, it prevents external dust and moisture from entering the rectangular box 1, improves heat dissipation performance, and prevents internal electrical components from being damaged by high temperatures, which is beneficial for use.

[0035] In summary, this biogas concentration alarm device, by adding an air intake function, can detect biogas concentration more quickly. It also filters dust, water vapor, and corrosive substances in the gas, ensuring accurate detection by the sensor component 3. Furthermore, the air intake mechanism 6 is less prone to clogging, improves heat dissipation performance, is less susceptible to high-temperature damage, and is easy to use.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
