Description

Technical Field

[0001] This utility model relates to the field of gas monitoring equipment technology, and specifically to a gas monitoring device for environmental protection. Background Technology

[0002] Gas monitoring equipment for environmental protection is a type of specialized equipment used to monitor the composition and concentration of gases in environments such as the atmosphere, industrial sites, and indoor spaces in real time. Through core components such as sensors and data processing units, it captures indicators such as toxic, harmful, flammable, explosive, or greenhouse gases, and realizes data collection, analysis, and early warning, providing data support for environmental supervision, pollution prevention and control, and environmental safety assurance.

[0003] Utility model patent CN220320706U discloses an energy-saving environmental gas monitoring device, including a gas monitor. An operating box is fixedly connected to the top of the gas monitor, and a turntable is rotatably connected to the top of the operating box. A second transmission rod is fixedly connected to the bottom of the turntable, and a limit ring is fixedly connected to the outer wall of the second transmission rod. In this utility model, rotating the handle drives the turntable, which in turn drives the solar panel. The solar panel is electrically connected to a battery, allowing the solar panel to rotate to the side exposed to sunlight, and enabling the battery to power the gas monitor at night. A support rod slides within a shaped rod, and after rotation, its top abuts against a limit block. The base slides upward to the top and rotates to the left, causing the slider to engage with the snap-fit ​​position of the shaped groove, simultaneously exposing the cone at the bottom of the central column, thus achieving overall stability on mud, tile, or cement surfaces.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: While existing gas monitoring equipment exhibits good stability and energy efficiency during use, in practical applications, its monitoring range is often limited to a finite area around the equipment installation point. For environments with wide spatial distribution, local concentration differences, or the need for multi-point monitoring, the data provided by a single monitoring point is insufficiently representative and cannot comprehensively reflect the overall gas distribution within the area. This necessitates the deployment of a large number of devices, resulting in high costs and difficult maintenance, thus reducing the effectiveness of gas monitoring equipment. Utility Model Content

[0014] Beneficial effects

[0016] I. This utility model, by setting up components such as a centralized input component and an adjustment and detection component, allows multiple sets of connecting pipes and a centralized head in the centralized input component to correspond to different monitoring points. In the adjustment and detection component, the motor drives the screw to rotate via a reducer, causing the screw sleeve to drive the push block to move.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] See attached document Figures 1-5 An environmental protection gas monitoring device includes: a monitoring device body 1 and a support frame 2. The bottom of the monitoring device body 1 is fixedly connected to the top of the support frame 2. A centralized input component 3 is connected to the top of the monitoring device body 1. The centralized input component 3 includes a blower 31. A centralized column 32 is connected to the top of the blower 31. Several sets of connecting pipes 33 are connected to one side of the centralized column 32. A centralized head 34 is connected to the other end of the connecting pipes 33. The blower 31 is existing technology. It is worth noting that the number of connecting pipes 33 can be adjusted according to actual use. When adjusting the number of connecting pipes 33, the corresponding number of structures also needs to be adjusted accordingly to meet normal use. An adjustment and detection assembly 4 is provided on the top of the monitoring device body 1. The adjustment and detection assembly 4 includes a motor 41, which is fixedly connected to the top of the central column 32. A reducer 42 is fixedly connected to the output end of the motor 41, and a screw 43 is fixedly connected to the output end of the reducer 42. A threaded sleeve 44 is threaded onto the surface of the screw 43. A push block 45 is fixedly connected to the side of the threaded sleeve 44 near the connecting pipe 33. A moving ring 46 is provided on one side of the connecting pipe 33, and a movable block 47 is provided on the side of the moving ring 46 near the threaded sleeve 44. The bottom of the moving ring 46 is fixedly connected to the connecting pipe 33 by a spring. The motor 41 is existing technology. The centralized input component 3 is powered by the blower 31. It collects gas from multiple areas through the centralized column 32, the connecting pipe 33 and the centralized head 34. The adjustment and detection component 4 drives the screw 43 to rotate through the motor 41 and the reducer 42, so that the screw sleeve 44 drives the push block 45 to move. Then, the movable block 47 pushes the moving ring 46 to slide in the connecting pipe 33. With the help of the spring, the position of the moving ring 46 is adjusted to realize the control of gas input to different connecting pipes 33. This allows a single device to monitor multiple points, expand the monitoring range, and reduce the equipment deployment cost and maintenance difficulty.

[0025] An electromagnetic block 5 is fixedly connected inside the pushing block 45. A movable block 6 is fixedly connected to the side of the electromagnetic block 5 near the movable block 47 via a spring and is magnetically connected to it. The movable block 6 is slidably connected inside the pushing block 45. The electromagnetic block 5 is existing technology. The electromagnetic block 5 and the movable block 6 are magnetically engaged, and combined with the spring, the sliding of the movable block 6 within the pushing block 45 can be controlled, thereby controlling the pushing of the movable block 47. This facilitates the control of the gas flow state of different connecting pipes 33. An inclined block 7 is fixedly connected to the bottom of the movable block 6. The top of the movable block 47 near the inclined block 7 is inclined. A friction block 8 is fixedly connected to the top of the movable block 6 near the movable block 47. When the movable block 6 moves to its top and resets, the bottom of the inclined block 7 contacts the inclined surface of the movable block 47, thereby pushing the movable block 47 to compress. The moving block 6 is reset, thus moving it to the bottom so that the movable blocks 47 can be pushed one by one when it moves up again. At the same time, the friction block 8 increases the friction between the moving block 6 and the movable blocks 47, preventing the movable blocks 47 from being accidentally compressed due to force when pushing the bottom of the movable blocks 47, effectively improving the pushing stability during use. A fixed rod 9 is fixedly connected to the side of the moving ring 46 near the movable blocks 47. The surface of the fixed rod 9 is slidably connected to the inside of the movable blocks 47. The movable blocks 47 are fixedly connected to the fixed rod 9 by a spring. The fixed rod 9 provides a sliding guide for the movable blocks 47. The spring resets the movable blocks 47 when there is no external force. When the inclined block 7 at the bottom of the moving block 6 pushes the top of the movable blocks 47, the movable blocks 47 can be squeezed and moved, so as not to affect the reset movement of the moving block 6.

[0026] A sealing ring 10 is fixedly connected to one side of the moving ring 46, and a strong magnetic block 11 is magnetically connected to the bottom of the moving ring 46. The strong magnetic block 11 is fixedly connected to the connecting pipe 33. The sealing ring 10 improves the sealing performance between the moving ring 46 and the connecting pipe 33, preventing gas leakage. The strong magnetic block 11 and the moving ring 46 are magnetically engaged, which can drive the moving ring 46 to position, enhancing the sealing effect in the closed state and avoiding the situation where gas leakage cannot be effectively detected. A filter ring 12 is fixedly connected to the other end of the concentrator 34. The filter ring 12 filters impurities in the gas and protects the monitoring device body 1. A trigger block 14 is fixedly connected to one side of the moving ring 46. A micro switch 15 is set on the top of the trigger block 14. The micro switch 15 is fixedly connected inside the concentrator 32. The movement of the moving ring 46 drives the trigger block 14, and the trigger block 14 triggers the micro switch 15. When the micro switch 15 is triggered, the motor 41 can be turned off and the time relay 16 can be started. When the time relay 16 finishes timing, it means that the sampling of a single connecting tube 33 has been completed. The time relay 16 can start the electromagnetic block 5. The time relay 16 is fixedly connected to the front of the monitoring device body 1. The time relay 16 is electrically connected to the motor 41 and the electromagnetic block 5 through the controller. The time relay 16 can be triggered by the micro switch 15. After the time relay 16 is triggered, it can start the electromagnetic block 5 at a time, so that the output of the electromagnetic block 5 generates a magnetic attraction to the moving block 6, so that the moving block 6 no longer pushes the movable block 47, thereby causing the movable block 47 to automatically reset and close the corresponding connecting tube 33. Then the moving block 6 can continue to push the subsequent movable blocks 47 in sequence, thereby causing the connecting tubes 33 to open sequentially for detection.

[0027] Working principle: When in use, the monitoring device body 1 and blower 31 are started. The blower 31 generates suction. In the initial state, the moving rings 46 in each connecting pipe 33 are in the closed position under the spring tension and the magnetic adsorption of the strong magnetic block 11. The sealing ring 10 is tightly attached to the inner wall of the connecting pipe 33 to prevent gas from flowing in directly without control and to ensure the accuracy of monitoring. Next, the starter motor 41 drives the screw 43 to rotate through the reducer 42. The screw sleeve 44 moves along the axial direction of the screw 43, and the push block 45 on one side moves synchronously. When the push block 45 approaches the movable block 47 of the first connecting pipe 33, the friction block 8 at the top of the movable block 6 contacts the bottom of the movable block 47 to increase the friction force and stably push the movable block 47, causing the movable block 47 to move and drive the fixed rod 9 to move, which in turn drives the movable ring 46 to move. The movable ring 46 moves and opens the corresponding connecting pipe 33. At this time, the blower 31 continuously generates suction force, which generates suction force on the corresponding concentrator 34 through the corresponding connecting pipe 33, causing the concentrator 34 to draw in the surrounding air and deliver the air to the monitoring equipment body 1 for detection through the connecting pipe 33 and the concentrator column 32. Simultaneously, the moving ring 46 moves, and the trigger block 14 on one side moves up and touches the micro switch 15. The micro switch 15 then sends a signal to the controller, which shuts off the motor 41 and starts the time relay 16 to start timing, ensuring that the gas at this point has enough time to be fully detected by the monitoring device body 1. When the time relay 16 finishes timing, indicating that the current point monitoring is complete, it sends a signal through the controller to activate the electromagnetic block 5. The output of the electromagnetic block 5 generates a magnetic attraction to the moving block 6, causing the moving block 6 to separate the friction block 8 from the movable block 47. Then, the motor 41 is activated, and the screw 43 continues to drive the screw sleeve 44 and the push block 45 to move. The push block 45 then approaches the movable block 47 of the next connecting pipe 33. Subsequently, the electromagnetic block 5 is automatically de-energized, causing the moving block 6 to automatically reset under the action of the spring. The above pushing process is repeated to open the next connecting pipe 33, realizing the switching of the monitoring point. During this process, the filter ring 12 at the concentration head 34 filters impurities in the gas to prevent dust and other substances from entering the equipment and affecting the sensor accuracy, ensuring the continuity of gas collection. Finally, through the above-mentioned cyclic process, the device can sequentially open different connecting pipes 33 to monitor the gas at multiple points in turn. This allows for wider monitoring coverage without the need to deploy multiple devices. Meanwhile, the sealing ring 10 always ensures the sealing of the moving ring 46 during the opening and closing process, preventing gas mixing at different points from interfering with the detection results. The strong magnetic block 11 enhances the sealing effect when the moving ring 46 is closed, improving the reliability of the monitoring data. This solves the problems of limited monitoring range and high cost of traditional equipment.
