Description

Technical Field

[0001] This utility model relates to the field of chemical safety testing technology, and in particular to a chemical safety testing device. Background Technology

[0002] The chemical industry involves the production, storage, transportation, and use of numerous hazardous chemicals, such as flammable and explosive hydrogen and methane, and toxic and harmful chlorine and hydrogen sulfide. Chemical production processes are complex, with high temperatures, high humidity, and strong corrosive conditions being common. Even slight negligence can lead to major safety accidents such as fires, explosions, and poisoning, causing casualties, property damage, and environmental pollution. Therefore, to ensure the safety of chemical production, personnel health, and the environment, it is essential to utilize chemical safety detection devices to monitor the production environment and equipment status in real time and accurately, promptly identifying and issuing warnings of hazardous factors. However, early chemical safety detection relied heavily on manual inspections and simple tools, such as smelling and observing appearances. These methods were highly subjective, inefficient, and inaccurate, making it difficult to detect potential hazards. Therefore, a safe and labor-saving detection device is needed.

[0003] However, most existing detection devices can only detect one or a few specific substances or parameters, such as the concentration of combustible gases. This makes them unable to effectively monitor the situation, leading to missed warnings and difficulty in meeting the comprehensive detection needs of complex chemical scenarios. Currently, the market is integrating artificial intelligence, big data, and IoT technologies to enable detection devices to have intelligent analysis, automatic diagnosis, fault warning, and remote monitoring functions, improving detection accuracy and management efficiency. However, in some complex chemical scenarios, because the detection devices can only detect a single gas, they cannot take into account other gases, temperature, humidity, and other important safety indicators. Furthermore, gas concentrations vary at different altitudes in chemical scenarios, making accurate detection impossible and failing to provide personnel protection, thus affecting production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a chemical safety detection device, which aims to improve the existing technology. However, in some complex chemical scenarios, the detection device can only detect a single gas, and the gas concentration varies at different altitudes, making it unable to accurately detect problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical safety detection device, comprising a housing, a transmission rod fixedly connected to the front outer wall near the edge of the housing, a knob rotatably connected to the top of the transmission rod, a transmission gear fixedly connected to the bottom of the transmission rod, an adjusting gear meshing with the right side of the outer wall of the transmission gear, a support rod fixedly connected to the middle of the outer wall of the adjusting gear, a power gear fixedly connected to the middle of the outer wall of the support rod, a lifting groove provided on the top right side of the housing, a lifting rod provided inside the lifting groove, a toothed groove provided at the bottom of the lifting rod, the outer walls of multiple toothed grooves meshing with the outer wall of the power gear, and a detection structure fixedly connected to the top of the lifting rod, the detection structure being used to detect gases of different components.

[0006] As a further description of the above technical solution:

A display is fixedly connected to the bottom of each of the multiple air inlet pipes. An alarm is fixedly connected to the top of the display. An exhaust pipe is fixedly connected to the rear outer wall of the display.

[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The buckle is rotatably connected to a pivot on the right side of its outer wall, and a connecting plate is fixedly connected to the right side of the pivot on its outer wall.

[0014] As a further description of the above technical solution:

[0015] A fixing column is fixedly connected to the right side of the outer wall of the connecting plate, and a connecting groove is provided on the left side of the outer wall of the fixing column.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the lifting rod is fixedly connected to a base, and the top end of the air intake pipe is fixedly connected to a dustproof net.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the transmission gear on the transmission rod is rotated by rotating the knob. Then, the power is transmitted to the adjustment gear through the transmission gear, thereby causing the power gear to rotate. Moreover, the toothed groove at the bottom of the lifting rod meshes with the power gear, thereby driving the lifting rod to move up and down, thus completing the height adjustment of the detection device.

[0030] 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.

[0031] Please see the appendix Figure 2 - Appendix Figure 4 This utility model provides an embodiment of a chemical safety detection device, comprising a housing 1. A transmission rod 3 is fixedly connected to the outer wall of the front side of the housing 1 near the edge. A knob 4 is rotatably connected to the top of the transmission rod 3. When the knob 4 is rotated, the transmission rod 3 rotates synchronously. A transmission gear 9 is fixedly connected to the bottom of the transmission rod 3. An adjusting gear 8 is meshed with the right side of the outer wall of the transmission gear 9. Under the drive of the transmission gear 9, the adjusting gear 8 also rotates. A support rod 10 is fixedly connected to the middle of the outer wall of the adjusting gear 8 for stable support. A power gear 7 is fixedly connected to the top of the housing 1. When the adjusting gear 8 rotates, it drives the support rod 10 and the power gear 7 to rotate together. A lifting groove 11 is provided on the top right side of the housing 1. A lifting rod 5 is provided inside the lifting groove 11 to provide a stable lifting track. A toothed groove 6 is provided at the bottom of the lifting rod 5. The outer walls of the multiple toothed grooves 6 mesh with the outer walls of the power gear 7. When the power gear 7 rotates, the teeth on its outer wall interact with the toothed grooves 6 at the bottom of the lifting rod 5. A detection structure 2 is fixedly connected to the top of the lifting rod 5. The detection structure 2 is used to detect gases of different components.

[0032] Specifically, when the knob 4 is rotated, the transmission rod 3 drives the transmission gear 9 to rotate, and the adjusting gear 8 rotates under the drive of the transmission gear 9. The synchronous support rod 10 and the power gear 7 rotate. When the power gear 7 rotates, the teeth on its outer wall interact with the toothed groove 6 at the bottom of the lifting rod 5, and then the rotational motion of the power gear 7 is transformed into the linear upward motion of the lifting rod 5.

[0033] Please see the appendix Figure 5 The detection structure 2 includes a detection box 201. The bottom of the detection box 201 is fixedly connected to the lifting rod 5. The top of the detection box 201 has a device groove 207 for equipment installation space. The outer wall of the detection box 201 is fixedly connected to an air inlet pipe 202. Gas enters the sensor through the air inlet pipe 202. The middle of the outer wall of the air inlet pipe 202 is fixedly connected to a combustible gas sensor 203, which uses a catalytic combustion method for detection. The middle of the outer wall of the air inlet pipe 202 is fixedly connected to a toxic gas sensor 204, which detects the concentration of toxic substances in the air. The middle of the outer wall of the air inlet pipe 202 is fixedly connected to a humidity sensor 205, which detects by linking humidity data with gas concentration. The bottom of the multiple air inlet pipes 202 is fixedly connected to a display 206 to display the sensor detection results. The top of the display 206 is fixedly connected to an alarm 209. The rear outer wall of the display 206 is fixedly connected to an exhaust pipe 208.

[0034] Specifically, as the lifting rod 5 rises, air is simultaneously drawn in by three air intake pipes 202, pre-treated, and then diverted. Subsequently, when passing through the combustible gas sensor 203, the toxic gas sensor 204, and the humidity sensor 205, the detected data is transmitted to the display 206, which displays the data. When the data fluctuates, the alarm 209 on the display 206 is triggered to alert the surrounding crowd.

[0035] Please see the appendix Figure 4 - Appendix Figure 5 A limiting gear 12 is fixedly connected to the middle of the outer wall of the transmission rod 3 to stop the lifting rod 5. A fixing block 20 is fixedly connected to the outer wall of the transmission rod 3 near the edge to prevent the transmission gear 9 from deviating. A buckle 13 is rotatably connected to the top of the outer wall of the limiting gear 12. A limiting switch 14 is fixedly connected to the left side of the outer wall of the buckle 13. When the limiting switch 14 is pushed down, the buckle 13 moves down at the same time to block the limiting gear 12, thereby stopping the lifting rod 5. A rotating shaft 15 is rotatably connected to the right side of the outer wall of the buckle 13. A connecting plate 16 is fixedly connected to the right side of the outer wall of the rotating shaft 15 to facilitate the downward movement of the buckle 13.

[0036] Specifically, when it is necessary to stop the ascent, simply move the limit switch 14 downwards. At this time, the buckle 13 connected to the limit switch 14 moves downwards, and the right-side rotating shaft 15 moves downwards along with the buckle 13. One side of the connecting plate 16 is connected to the rotating shaft 15, and the other side is connected to the fixed column 18, which assists the buckle 13 in descending. After the buckle 13 descends, it blocks the limit gear 12, preventing it from rotating.

[0037] Please see the appendix Figure 1 - Appendix Figure 2 The bottom end of the lifting rod 5 is fixedly connected to the base 22, and the top end of the air inlet pipe 202 is fixedly connected to the dustproof net 23 to prevent air dust from entering the sensor and affecting the detection results. The right side of the outer wall of the connecting plate 16 is fixedly connected to the fixing column 18. The left side of the outer wall of the fixing column 18 is provided with a connecting groove 17 to assist the buckle 13 to move downward. The left side of the outer wall of the housing 1 is provided with a limit groove 19 near the edge to prevent the limit switch 14 from being pushed down too much and damaging the limit structure. The upper and lower ends of the inside of the housing 1 are fixedly connected to limit the movement of the lifting rod 5.

[0038] Specifically, when the detection device is working, the top of its air intake pipe 202 is wrapped with a dustproof net 23 to prevent air dust from entering, and the connecting groove 17 on the fixed column 18 provides working space for the connecting plate 16, while the limiting groove 19 prevents the limit switch 14 from working in a fixed space.

[0039] Working principle: First, rotate knob 4. Since knob 4 is connected to transmission rod 3, when knob 4 rotates, transmission rod 3 rotates accordingly. Then, transmission gear 9 on transmission rod 3 rotates accordingly. Since transmission gear 9 meshes with adjusting gear 8, power is transmitted to adjusting gear 8 through transmission gear 9, causing adjusting gear 8 to rotate. Then, adjusting gear 8 and power gear 7 are located on support rod 10. When adjusting gear 8 rotates, it causes power gear 7 on support rod 10 to rotate. Since the bottom of lifting rod 5 has a toothed groove 6 that meshes with power gear 7, when power gear 7 rotates, it drives lifting rod 5 to move upward, thereby realizing height adjustment and facilitating the detection of safety risks at different heights.

[0040] As the lifting rod 5 rises, the detection box 201, connected to the lifting rod 5, activates multiple detection devices inside the detection box 201 to check for safety hazards. Gas enters through the inlet pipe 202, then passes through the combustible gas sensor 203, the toxic gas sensor 204, and the humidity sensor 205. The sensitive elements inside these sensors convert the detected physical quantities into electrical signals, which are then transmitted to the data acquisition system under the display 206 via their respective signal lines. The gas concentration can be viewed on the display 206. When the gas concentration detected by a sensor exceeds the alarm threshold, the system will immediately issue an alarm signal. At this time, the device recess 207 above the display 206 will emit a sound to alert those nearby.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
