Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figure 1-7 As shown, this embodiment provides a combustible gas monitoring alarm, including a gas discharge pipe 1, a mounting base 2 on one side of the gas discharge pipe 1, a gas monitoring box 3 on the mounting base 2, and a through groove 4 corresponding to the gas monitoring box 3 on one side of the gas discharge pipe 1.

[0034] The mounting base 2 is provided with a mounting groove 5 corresponding to the gas monitoring box 3. A fixing plate 6 is provided on one side of the mounting groove 5. The mounting base 2 is provided with a drive mechanism connected to the gas monitoring box 3. A first mounting frame 7 is elastically fitted in the through groove 4. Both sides of the first mounting frame 7 are provided with through holes corresponding to and communicating with the through groove 4. A placement groove 8 connected to the through hole is opened on the upper side of the first mounting frame 7. A filter screen 9 is provided in the placement groove 8. An embedding groove 10 is provided on the lower side of the first mounting frame 7. An embedding inclined plate 11 is provided on the drive mechanism.

[0035] One application of this embodiment is as follows: When the gas monitoring box 3 needs to be disassembled for maintenance, the drive mechanism is activated to move the fixing plate 6, releasing the limit on the gas monitoring box 3. At the same time, the drive mechanism is linked to the embedded inclined plate 11 sliding out from the embedded groove 10, releasing the constraint on the first mounting frame 7. After the gas monitoring box 3 is removed, the first mounting frame 7 pops out from the through groove 4 by its own elasticity, reminding the staff to perform filter maintenance with a visual physical change. At this time, the filter 9 can be easily taken out from the placement groove 8 for replacement. After the filter 9 is replaced and the gas monitoring box 3 is repaired, the monitoring box is reinstalled. Its downward pressure makes the first mounting frame 7 reset. Then, the drive mechanism is activated in reverse to move the fixing plate 6 back into place, and the embedded inclined plate 11 is reinserted into the embedded groove 10 for fixation. This completes the maintenance operation process of the entire device.

[0036] By setting the fixing plate 6, its position can be flexibly adjusted under the action of the drive mechanism. This design can conveniently realize the fixing and disassembly of the gas monitoring box 3 in the mounting slot 5. Compared with the traditional bolt fixing method, it greatly improves work efficiency and saves time and labor costs. When the gas monitoring box 3 is disassembled, the first mounting frame 7 pops it out with its own elasticity. This function not only makes it easy for staff to quickly remove the gas monitoring box 3, but also reminds staff to inspect and replace the filter screen 9 in a visual way, effectively avoiding the omission of maintenance work on the filter screen 9 when inspecting the gas monitoring box 3. In addition, the reasonable design of the placement slot 8 provides convenient conditions for the removal of the filter screen 9, making the disassembly and replacement of the filter screen 9 easier and more efficient.

[0037] like Figure 6 As shown, a connecting groove 12 is provided on one side of the gas monitoring box 3 in this embodiment, which corresponds to the through hole on one side of the first mounting frame 7. The design of the connecting groove 12 creates a gas transmission channel, which can efficiently absorb the gas entering through the through hole and accurately deliver it into the gas monitoring box 3. Through this ingenious design, the gas can flow into the monitoring box in an orderly and stable manner, ensuring that the monitoring box can accurately detect and analyze key indicators such as gas composition and concentration, providing a reliable basis for subsequent data processing and decision-making.

[0038] like Figure 1-3 As shown in Figure 7, the drive mechanism of this embodiment includes a lead screw 13 threadedly engaged with one side of the mounting base 2, a fixing plate 6 threadedly engaged with the lead screw 13, a handle 14 provided at one end of the lead screw 13, a rectangular telescopic plate 15 provided at the other end of the lead screw 13, a rectangular telescopic frame 16 provided on one side of the rectangular telescopic plate 15, wherein the rectangular telescopic plate 15 is slidably engaged within the rectangular telescopic frame 16; a connecting shaft 17 is provided at one end of the rectangular telescopic frame 16, a gear 18 is provided at one end of the connecting shaft 17, and a toothed plate 19 that meshes with the gear 18 is provided at one end of the embedded inclined plate 11. The ergonomic design of the handle 14 provides a convenient point of leverage for operators to control the lead screw 13. By rotating the handle 14, the lead screw 13 is driven to rotate, and the precise displacement of the fixed plate 6 is achieved by utilizing the thread meshing principle. During this process, the rectangular telescopic plate 15 slides smoothly within the rectangular telescopic frame 16. With the guiding characteristics of the rectangular structure, the gear 18 at one end of the connecting shaft 17 rotates synchronously. The rotation of the gear 18 then drives the toothed plate 19 to move linearly, precisely controlling the engagement or disengagement of the embedded inclined plate 11 and the embedded groove 10, effectively achieving the limit control of the first mounting frame 7. This linkage mechanism not only ensures the stability of the fixed state of the first mounting frame 7, but also forms a smooth and logically rigorous mechanical transmission system.

[0039] like Figure 2 and 5As shown, in this embodiment, a second mounting frame 20 is provided inside the gas discharge pipe 1. A fan 21 is rotatably fitted inside the second mounting frame 20. A stirring rod 22 is provided on the upper side of the fan 21, and multiple evenly distributed stirring blades 23 are provided around the stirring rod 22. The fan 21 and the multiple stirring blades 23 work together to form a highly efficient mixed gas stirring system. When the mixed gas enters the gas discharge pipe 1, the airflow generated by the fan 21 drives the gas flow, while the stirring blades 23 agitate the gas in all directions, breaking up the gas stratification and allowing the mixed gas to be fully mixed in the discharge pipe. The fully stirred mixed gas can pass through the through hole and the through groove 4 evenly and stably, and enter the gas monitoring box 3 in an orderly manner. This design effectively avoids monitoring errors caused by uneven gas distribution, greatly improves the accuracy and reliability of gas monitoring data, and ensures that gas monitoring work is carried out efficiently and accurately.

[0040] like Figure 2 and 6 As shown, in this embodiment, a plurality of combustible gas alarm monitoring heads 24 are installed on one side of the inner wall of the gas monitoring box 3. The combustible gas alarm monitoring heads 24 are evenly distributed on one side of the inner wall of the gas monitoring box 3 and correspond to the connecting groove 12. An alarm is installed on one side of the gas monitoring box 3, which is electrically connected to the combustible gas alarm monitoring heads 24. The scientific layout of the plurality of combustible gas alarm monitoring heads 24 constructs a tight gas monitoring network. These monitoring heads perform real-time, multi-dimensional detection of the gas entering the gas monitoring box 3 through the connecting groove 12. Through multi-node data acquisition and cross-verification, the accuracy and reliability of the monitoring results are effectively improved. Once the combustible gas monitoring head 24 detects that the concentration of combustible gas in the pipeline exceeds the safety threshold, the alarm will be activated immediately, and the staff will be alerted quickly by means of sound and light warnings. This immediate warning mechanism buys valuable time for emergency response, making it easier for staff to take effective measures such as ventilation and cutting off the gas source in a timely manner, curbing safety hazards from the source, minimizing the risk of major safety accidents, and building a solid safety line for production and operation.

[0041] like Figure 6 As shown, the gas monitoring box 3 in this embodiment has a pull-out groove 25 on one side, and a dust collection drawer 26 is slidably fitted inside the pull-out groove 25. A pull-out handle 27 is located on one side of the dust collection drawer 26. The ingenious design of the dust collection drawer 26 facilitates the daily maintenance of the gas monitoring box 3. Operators can easily pull the dust collection drawer 26 smoothly out of the pull-out groove 25 by simply pulling the pull-out handle 27. This structural design allows dust deposited on the inner wall of the gas monitoring box 3 to be collected and stored, facilitating regular cleaning and effectively preventing dust accumulation from affecting the normal operation of the monitoring equipment. Furthermore, the ergonomic shape and grip design of the pull-out handle 27 further optimizes the operating experience, making cleaning easier and more efficient, significantly improving the convenience and efficiency of equipment maintenance.

[0042] like Figure 4 As shown, the gas monitoring box 3 in this embodiment is provided with snap-fit ​​plates 28 on both sides, and snap-fit ​​grooves 29 are provided on both sides of the inner wall of the mounting groove 5. The snap-fit ​​plates 28 are snapped into the snap-fit ​​grooves 29. The design of the snap-fit ​​grooves 29 provides a stable foundation support for the installation of the gas monitoring box 3. When the snap-fit ​​plates 28 on the gas monitoring box 3 are accurately embedded into the snap-fit ​​grooves 29, the monitoring box can be initially positioned and fixed, quickly completing the first step of equipment installation. This pre-fixed structure effectively reduces the difficulty of subsequent installation of the fixing plate 6, ensuring that the fixing plate 6 can more accurately and efficiently reinforce the gas monitoring box 3, which not only improves the installation efficiency but also enhances the stability of the overall structure, providing a reliable guarantee for the smooth operation of gas monitoring.

[0043] In this embodiment, the embedded inclined plate 11 has an inclined surface on one side, which allows it to squeeze and move the first mounting frame 7 when it enters the embedded groove 10, so that the first mounting frame 7 can be installed into the through groove 4, thereby improving the stability of the first mounting frame 7 during installation.

[0044] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
