DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 3 and 4 The present invention provides an embodiment of a modular gas alarm device, comprising a fixed shell 1, a cylinder 7 is mounted on one side of the inner wall of the fixed shell 1, and the fixed shell 1 has a position fixing function for the cylinder 7 (such as the attached Figure 3 The inner wall of the right end of the fixed shell 1 is fixedly connected with four support rods 5, and the fixed shell 1 has the function of fixing the position of the four support rods 5. The tops of the four support rods 5 are fixedly connected with a limit shell 6, and the four support rods 5 have the function of fixing the position of the limit shell 6.

[0032] The driving end of the cylinder 7 is fixedly connected to a toothed plate 8. Starting the cylinder 7 can move the toothed plate 8. Two slideways are provided inside the fixed housing 1. The bottom of the toothed plate 8 is slidably connected to the inner wall of one of the slideways. If the cylinder 7 drives the toothed plate 8 to move toward the cylinder 7, the toothed plate 8 will move parallel to the driving end of the cylinder 7. The inner wall of the fixed housing 1 is rotatably connected to a gear 9. The fixed housing 1 has a fixed effect on the position of the gear 9. The outer part of the toothed plate 8 is meshed with the outer part of the gear 9 (as shown in the attached figure). Figure 4 ), the movement of the tooth plate 8 drives the rotation of the gear 9.

[0033] The inner wall of the other slideway is slidably connected to tooth plate 2 (10). The outer portion of tooth plate 2 (10) meshes with the outer portion of gear 9, away from tooth plate 1 (8). Rotation of gear 9 causes tooth plate 2 (10) to move as well. Because tooth plate 1 (8) and tooth plate 2 (10) mesh with different sides of gear 9, rotation of gear 9 drives both to move synchronously. When tooth plate 1 (8) moves toward the contraction of cylinder 7, tooth plate 2 (10) moves toward the other end.

[0034] The outside of tooth plate 1 8 is fixedly connected to a sliding block 11. The movement of tooth plate 1 8 drives sliding block 11 toward the retracted side of cylinder 7. The other end of sliding block 11 is fixedly connected to a limiting block 12. The movement of sliding block 11 drives limiting block 12 toward the retracted side of cylinder 7, causing limiting block 12 to engage with the inner notch of fixed frame 3. The top of tooth plate 2 10 is fixedly connected to sliding block 2 13. The movement of tooth plate 2 10 drives sliding block 2 13 in the opposite direction of sliding block 11. The other end of sliding block 2 13 is fixedly connected to a limiting block 2 14. The movement of sliding block 2 13 drives limiting block 2 14 in the opposite direction of limiting block 12, causing limiting block 2 14 to engage with the other notch of fixed frame 3. This allows fixed frame 3 to be stably fixed to the inner wall of limiting housing 6, maintaining the same positional stability as fixed housing 1, and fixed housing 1 is mounted on a wall.

[0035] Reference Figures 1 to 2 The inner wall of the limiting housing 6 is detachably connected to a fixing frame 3. The other end of the fixing frame 3 is fixedly connected to the sensing frame 4, so that when the fixing frame 3 is fixed, the position of the sensing frame 4 is also limited. A warning assembly for warning of dangerous gases is fixedly connected to the outer side of the sensing frame 4. The warning assembly includes a motor 17. The drive end of the motor 17 is fixedly connected to a transmission block 19. Starting the motor 17 drives the rotation of the transmission block 19.

[0036] The other end of the transmission block 19 is rotatably connected to the warning light 21. The rotation of the transmission block 19 drives the rotation of the warning light 21. The transmission block 19 is a solid block with a slight curvature (as shown in the attached diagram). Figure 2), so that the rotation of the warning light 21 can be carried out around the driving end of the motor 17, so that the light of the warning light 21 is more focused in a small range and easier to observe. Compared with the traditional warning light, the moving light is easier to be noticed by people.

[0037] The motor 17 is fixedly connected to two mounting brackets 18 on its exterior, securing them in position. A rotating frame 20 is pivotally connected to adjacent sides of the two mounting brackets 18, providing support for the latter. The outer center of the warning light 21 is pivotally connected to the interior of the rotating frame 20, providing support during rotation to prevent it from sinking due to gravity, which would otherwise affect the warning effect.

[0038] The inner wall of the sensing frame 4 is threadedly connected with a gas sensor 15, so that when the gas sensor 15 is damaged, non-technical personnel can also disassemble and replace the gas sensor 15. The outside of the sensing frame 4 is provided with a plurality of small holes (such as the attached Figure 1 ), so that more gas can enter the interior of the sensing frame 4 through the small holes, thereby being sensed by the gas sensor 15 and then reacting. The gas sensor 15 is an instrument with model TGS2600-B00 in the prior art, and will not be described in detail here.

[0039] A display screen 2 is installed on the outside of the sensing frame 4, and an information processor 16 is installed on the other end of the display screen 2. There are connecting wires between the gas sensor 15 and the information processor 16. Therefore, when the gas sensor 15 senses gas, it can distinguish it from the data in the gas library inside the information processor 16, thereby making a judgment on whether it is a harmful gas, and then reflecting the judgment on the display screen 2.

[0040] Working principle: First, fix the fixed shell 1 on the wall, align the outside of the fixed frame 3 with the slot of the limit shell 6, and then start the cylinder 7, so that the cylinder 7 pushes the tooth plate 1 8. The movement of the tooth plate 1 8 drives the rotation of the gear 9. The rotation of the gear 9 causes the tooth plate 2 10 to move. If the tooth plate 1 8 and the tooth plate 2 10 move away from each other, they will respectively drive the sliding block 1 11 and the sliding block 2 13 on their tops to move away from each other. The movement of the sliding block 1 11 and the sliding block 2 13 away from each other respectively drives the limit block 1 12 and the limit block 2 14 on their outsides to move away from each other, so that the limit block 12 and the limit block 2 14 engage with the notch inside the fixed frame 3, and the outside of the sensing frame 4 is fixedly connected to the outside of the fixed frame 3. Therefore, the above operation is equivalent to fixing the sensing frame 4. If disassembly is required, just reverse the cylinder 7. This makes the fixing and removal of the sensor frame 4 more convenient, making the device more suitable for people's daily use. During the removal and replacement process, the wall itself does not need to be damaged, which provides a certain degree of protection for the wall. If harmful gases appear in the air, the information processor 16 will react quickly, energizing the warning light 21 and controlling the motor 17 to start, driving the transmission block 19 at its drive end to rotate, causing the warning light 21 at the other end of the transmission block 19 to rotate, causing the room to appear to be surrounded by light. Compared with simply lighting the warning light 21, it is more intuitive. When people are not paying attention to the status of the warning light 21, the surrounding light will also fall into their peripheral vision to warn them, thereby enhancing the warning effect.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
