Description

Technical Field

[0001] This utility model relates to the technical field of gas detection devices, and in particular to a multi-parameter detection device for gas detection. Background Technology

[0002] A multi-parameter gas detection device is a device that integrates multiple gas sensors and data processing technologies, enabling real-time, continuous, and accurate detection of various gas components in the environment.

[0003] In coastal areas, the high humidity places stringent demands on the performance of gas detection devices. Existing gas detection devices used in such environments typically employ a container filled with activated carbon in the air intake channel. The activated carbon adsorbs moisture from the gas, preventing excessive moisture from affecting the detection accuracy. Simultaneously, a dust filter is installed at the air intake to prevent dust and impurities from entering the detection device.

[0004] However, in existing devices, activated carbon is often in a static state, resulting in insufficient contact with the gas and low adsorption efficiency. This necessitates frequent replacement of the activated carbon, increasing maintenance costs and affecting the continuity of detection work. Furthermore, the dust filter lacks an effective cleaning mechanism during the interception of dust and impurities, allowing activated carbon debris and airborne dust to accumulate on the filter, causing blockage and hindering gas flow, thus reducing detection efficiency. Therefore, a multi-parameter gas detection device is proposed to address these issues. Utility Model Content

[0023] 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.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multi-parameter gas detection device, including a base 1. The base 1 supports the entire detection device, ensuring its stability and providing a foundation for other components. A detection device 2 is placed on top of the base 1. The detection device 2 is used to perform multi-parameter detection on the incoming gas, analyzing various components and their concentrations in the gas. It is the core component for the entire device to achieve gas detection. A pipe 3 contacts the outer wall of the inlet of the detection device 2. The pipe 3 is responsible for transmitting the gas to be detected to the inlet of the detection device 2, serving as the channel for the gas to enter the detection device 2. The inlet of the detection device 2 has a threaded groove, and the outer wall of the pipe 3 has a threaded hole. The detection device 2 is threadedly connected to the outer wall of the pipe 3 by bolts 5. This threaded connection facilitates installation and disassembly, allowing the detection device 2 to be separated from or connected to the pipe 3 when maintenance, component replacement, or device adjustment is required, ensuring the airtightness of the gas transmission channel. An intake fan is fixedly installed on the inner wall of the pipe 3. 6. After the intake fan 6 starts, it generates suction, which causes external gas to quickly enter the interior of the pipe 3, accelerating the gas flow and improving detection efficiency. The inner side of the pipe 3 is in contact with a rotating cylinder 13, which plays a role in pre-treating the gas and assisting in the adsorption of moisture in the device. The substance filled inside the cylinder can perform relevant treatments on the gas. The end face of the rotating cylinder 13 is fixedly connected to the output shaft of the intake fan 6. This connection method allows the intake fan 6 to drive the rotating cylinder 13 to rotate synchronously, realizing the correlation between their movements. The outer wall of the rotating cylinder 13 is hollowed out, which allows gas to freely enter and exit the interior of the rotating cylinder 13, ensuring that the substance filled inside the rotating cylinder 13 is in full contact with the external gas, thus realizing the gas treatment function. A dustproof net 7 is fixedly connected to the outer wall of the rotating cylinder 13. The dustproof net 7 can intercept larger dust particles in the air, preventing dust from entering the interior of the detection device 2 and avoiding dust from contaminating or damaging the sensors and other components of the detection device 2, affecting the detection accuracy and equipment life. A cleaning component is installed below the rotating cylinder 13.

[0025] Reference Figure 2 , Figure 3The cleaning assembly includes a rotating rod with a cleaning roller 10 fixedly mounted on its surface. The cleaning roller 10 rotates under the drive of the rotating rod to clean the surface of the dustproof net 7, removing dust, activated carbon residue, and other impurities. A toothed ring 8 is fixedly mounted on the outer wall of the rotating drum 13, rotating with the drum 13. The bottom of the toothed ring 8 meshes with the top of the driven gear 11. Through this meshing relationship, when the toothed ring 8 rotates, the driven gear 11 is driven to rotate, which in turn drives the connected rotating rod and cleaning roller 10 to rotate, achieving automatic cleaning of the dustproof net 7. The surface of the cleaning roller 10 contacts the surface of the dustproof net 7. During the rotation of the cleaning roller 10, the contact between its surface and the surface of the dustproof net 7 scrapes off impurities, keeping the dustproof net 7 clean, ensuring good ventilation, and preventing blockage. A slide rail is fixedly connected to the top of the base 1, and a collection box 4 is slidably connected to the slide rail. The collection box 4 can slide on the slide rail for easy installation, removal, and cleaning. The collection box 4 is used to collect activated carbon residue and dust and other impurities that fall from the dustproof net 7 and the rotating drum 13. The outer wall of the collection box 4 is fixedly connected to a handle A, which is convenient for the operator to hold and pull the collection box 4 out of the slide rail for cleaning and maintenance. The collection box 4 is located below the cleaning roller 10. This position ensures that the impurities cleaned from the dustproof net 7 and the rotating drum 13 can fall directly into the collection box 4 for centralized collection and treatment. The bottom of the pipe 3 is fixedly connected to a support block 9, and the bottom of the support block 9 is fixedly connected to the top of the base 1. The support blocks 9 are symmetrically arranged on the top of the base 1. The support blocks 9 support the pipe 3 and enhance the stability of the pipe 3 in the device, so that it will not shake or shift during gas transmission. Both ends of the rotating rod are rotatably connected to the side of the support block 9. The rotating rod can rotate stably under the support of the support block 9 through the rotatable connection with the support block 9, providing rotational power for the cleaning roller 10. The rotating drum 13 is equipped with a material changing component.

[0026] Reference Figure 3The material changing assembly includes a hinged plate 12, which is hinged to the end face of the rotating drum 13. This allows the hinged plate 12 to rotate around the hinge point, opening and closing the internal space of the rotating drum 13 for easy replacement of materials such as activated carbon. The hinged plate 12 is hinged to the end face of the rotating drum 13, which has an opening. The air inlet of the testing device 2 is in close contact with the end face of the hinged plate 12. This close contact ensures the airtightness of the gas entering the testing device 2 from the rotating drum 13, preventing gas leakage and ensuring the accuracy of the test results. The inner side of the hinged plate 12 is filled with an intercepting mesh, which further intercepts impurities in the gas, preventing larger particles from entering the testing device 2 and providing additional protection for the testing device 2. The top of the base 1 has a sliding groove, and the bottom of the testing device 2 is fixedly connected to... The bottom of the detection device 2 is slidably connected to the inner wall of the slide groove via a slider. The detection device 2 can slide on the base 1 through the cooperation of the slider and the slide groove, facilitating the separation of the detection device 2 from the pipe 3 when the material inside the rotating drum 13 needs to be changed. A handle B is fixedly connected to the side of the detection device 2, allowing the operator to pull the detection device 2 and slide it within the slide groove to adjust its position. Magnets are respectively provided on the side adjacent to the rotating drum 13 and the opening / closing plate 12. The side adjacent to the rotating drum 13 is magnetically connected by the magnets. Through this magnetic connection, the opening / closing plate 12 can tightly fit onto the rotating drum 13 during normal operation, ensuring the sealing of the rotating drum 13. When it is necessary to open the opening / closing plate 12, it can be easily opened after overcoming the magnetic attraction, making it convenient and quick.

[0027] Working Principle: When testing is required, simply start the intake fan 6. The intake fan 6 forces external air into the pipe 3. The output shaft of the intake fan 6 drives the rotating drum 13 to rotate. The inside of the rotating drum 13 is filled with activated carbon. The rotating activated carbon adsorbs moisture from the air, allowing external air to enter the testing device 2 for detection. Since the adsorption effect of activated carbon is poor when stationary, it requires frequent inspection or replacement. This device improves the utilization efficiency of the activated carbon by repeatedly turning it inside the rotating drum 13, extending its moisture absorption effect. As the activated carbon turns, fragments fall into the collection box 4 below. Combined with the meshing of the gear ring 8 and the driven gear 11, the activated carbon... The rotating rod and cleaning roller 10 are driven to rotate respectively. The rotating cleaning roller 10 cleans the dust screen 7. This is to prevent the dust screen 7 from being clogged by too much activated carbon residue, and the dust screen 7 can intercept larger dust particles in the air. The rotation of the cleaning roller 10 scrapes off the dust on its surface, improving efficiency. When the activated carbon needs to be replaced, simply remove the bolt 5 on the outer wall of the pipe 3, and then pull the handle B. The handle B will pull the detection device 2. The bottom of the detection device 2 will slide in the slide groove through the slider, separating the air inlet of the detection device 2 from the pipe 3. Then, under the action of the magnet, the opening and closing plate 12 can be easily opened to facilitate the replacement of the activated carbon inside the rotating drum 13. After replacement, it can be returned to its original position.
