Description

Technical Field

[0001] This invention relates to the field of gaseous pollutant monitoring technology, specifically to a guided gaseous pollutant monitoring device. Background Technology

[0002] As an important part of social environmental protection needs, gas quality monitoring technology has put forward higher requirements for the monitoring level of various gaseous pollutants and greenhouse gases. Therefore, the monitoring quality of gaseous pollutants, with its demand for high efficiency and accuracy, has become a key development direction.

[0003] For example, patent CN113109506A discloses a gas collection device, particularly a multi-point collection system for various gaseous pollutants. It includes a multi-point sampling box and a gaseous pollutant collection cabinet. The multi-point sampling box has multiple air inlets and one air outlet, with one of the multiple air inlets connected to the air outlet. The side wall of the gaseous pollutant collection cabinet has a cabinet air inlet and a cabinet air outlet. The sensor-inhalation chamber includes multiple sensors, each used to collect different gaseous pollutant concentrations. A pressure transmitter and a mass flow meter are installed in the airflow pipeline from the cabinet air inlet through the sensor-inhalation chamber to the cabinet air outlet. A vacuum pump and a valve are also installed in this airflow pipeline. The air outlet of the multi-point sampling box and the air inlet of the gaseous pollutant collection cabinet are connected.

[0004] For example, patent CN203658345U discloses an atmospheric prevention and warning device, belonging to the field of environmental monitoring structure technology. The particulate warning mechanism and the gaseous pollutant warning mechanism are connected through a sampling tube, and the gaseous pollutant warning mechanism is connected to a wind pump through a connecting tube. The bottom of the gaseous pollutant warning mechanism is equipped with a bracket, which is respectively set with particulate pollutant warning mechanism and gaseous pollutant warning mechanism. It can detect and warn of multiple pollutants in the atmosphere. It is easy to operate and can provide warnings of different levels, so as to detect different levels of atmospheric pollution. At the same time, the sewage sample can be placed into the reaction liquid tube through the detachable cover plate on the top of the sealed container II to detect the degree of water pollution. It realizes multiple uses of one machine and helps to save on procedures and costs.

[0005] For example, the patent with publication number CN211014213U in the field of integrated unit gas monitoring technology is specifically a gas pollutant concentration monitoring mechanism for an integrated unit equipment. It includes an integrated unit and an air outlet set on the front side of its top. The top of the integrated unit is provided with several air inlets. A gas-gathering hood is installed above the air inlets. A gas monitor is fixed on the rear side of the gas-gathering hood. An insertion hole is opened in the middle section of the rear side of the gas-gathering hood. A cover is snapped onto the top of the gas-gathering hood. A detection end is installed on the front side of the gas monitor. The detection end is inserted and matched with the insertion hole. A gas monitor is also installed on one side of the gas-gathering hood to monitor the concentration of gas pollutants absorbed by the integrated unit. When the preset value is reached, an automatic warning is issued. A cover with activated carbon blocks can be added to the top of the air inlet to purify the absorbed gas.

[0006] Most of the aforementioned existing technologies improve the overall structure. However, in the process of air sampling and monitoring, existing gas pollutant monitoring equipment tends to retain some of the gas sample from the previous sampling after a single sampling. This causes a lag in the detection data during subsequent detections, and the overall pre-processing detection process cannot be guaranteed, resulting in certain defects in detection accuracy and ultimately compromising the overall accuracy of the equipment. Summary of the Invention

[0007] The purpose of this invention is to provide a guided gaseous pollutant monitoring device to solve the problem mentioned in the background art that after a single sampling, some gas samples from the previous sampling are easily retained inside the device, causing a lag in the detection data during subsequent detection, making it impossible to guarantee the overall pre-processing detection process, and resulting in certain defects in detection accuracy.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a guided gaseous pollutant monitoring device, comprising a monitoring device body, wherein a pre-installed suction pipe is internally connected to the monitoring device body, and a pre-installed air pump component is installed inside the monitoring device body, and the pre-installed suction pipe is connected to the pre-installed air pump structure inside the monitoring device body for suction detection processing; a driving component is installed inside the monitoring device body, a horizontally nested connecting piece is installed on the inner side of the monitoring device body, and a sealing connecting piece is nested on the inner side of the middle end of the monitoring device body, and the sealing connecting piece is internally connected to the pre-installed suction pipe; a guided self-accumulating gas structure is provided between the pre-installed suction pipe and the monitoring device body, and the quality of the sampled gas inside the pre-installed suction pipe is pre-treated and controlled by the guided self-accumulating gas structure.

[0009] More preferably, the driving component is a first built-in push rod, and the lower end of the first built-in push rod is vertically connected to the inner side of the suction reserved tube, and the output end of the first built-in push rod is connected to an abutment limiting member. Magnet docking members are fixedly connected to the outer side of the horizontal docking member and the outer side of the upper end of the abutment limiting member.

[0010] More preferably, the guiding self-accumulating structure is provided with a built-in steel wire rope, one end of which is connected to the outer side of the upper end of the horizontal docking member, and the middle section of the built-in steel wire rope runs through the inner side of the monitoring device body. At the same time, the end of the built-in steel wire rope is connected to the outer side of the sealing docking member to form a traction structure. A first spring is fixedly connected to the outer side of the sealing docking member, and the first spring is connected to the inner side of the monitoring device body. An air storage reserved cavity is opened inside the monitoring device body, and a fitting piston is nested inside the air storage reserved cavity. The lower end of the fitting piston is connected to the upper end of the horizontal docking member. A reserved through hole is opened on the outer side of the air storage reserved cavity, and a second spring is fixedly connected to the inner side of the air storage reserved cavity. The second spring is connected to the outer side of the fitting piston.

[0011] In a further preferred embodiment, the abutting limiting member moves downward along the inner side of the suction reserved passage tube by being driven by the first built-in push rod, and the abutting limiting member, in conjunction with the inclined structure at its upper end and the magnet docking member with the same magnetic pole, pushes the outer horizontal docking member to move laterally, and the horizontal docking member drives the sealing docking member to form a traction structure through the built-in steel wire rope.

[0012] More preferably, the transverse docking member and the fitting piston member are an integrated structure, and the fitting piston member fits and moves along the inner side of the gas storage reserved cavity.

[0013] Further preferably, the inner side of the suction reserved passage is provided with a guiding discharge structure, which releases the residual gas stored inside the suction reserved passage; the guiding discharge structure is provided with a retaining element, which is nested and connected to the inner side of the gas storage reserved cavity; the monitoring device body is internally bonded with a built-in first liquid bladder, and the outer side of the built-in first liquid bladder is connected to the outer side of the retaining element; a supply hose is connected through the outer side of the built-in first liquid bladder, and the supply hose runs through the interior of the monitoring device body; a sealing vertical member is nested and installed inside the reserved through hole, and the upper end of the sealing vertical member is bonded and connected to a built-in second liquid bladder, which is connected to the interior of the monitoring device body, and the upper end of the built-in second liquid bladder is connected to the end of the supply hose.

[0014] More preferably, a fixed connecting rod is fixedly connected to the outer side of the fitting piston component, and the fixed connecting rod passes through the interior of the monitoring device body. A guide fitting component is rotatably connected to the inner wall of the suction reserved passage tube, and the inner position of the guide fitting component corresponds to the outer position of the fixed connecting rod. A third spring is fixedly connected to the outer side of the guide fitting component, and the third spring is mated with the inner wall of the suction reserved passage tube.

[0015] More preferably, during the lateral movement of the fitting piston along the inner side of the gas storage cavity, it simultaneously applies pressure to the contacting retaining member, and the contacting retaining member presses against the inner built-in first liquid bladder. The built-in first liquid bladder supplies power to the inside of the built-in second liquid bladder through the supply hose, and the built-in second liquid bladder expands vertically to push the contacting sealing vertical member downward.

[0016] In a further preferred embodiment, during the lateral movement of the fitting piston, the outer fixed connecting rod is moved synchronously, and the fixed connecting rod applies pressure to the contacting guide fitting member to rotate outward, and the guide fitting member forms an elastic support structure with the inner wall of the suction reserved passage through the third spring.

[0017] More preferably, the driving component is a second built-in push rod, which is laterally connected to the inside of the monitoring device body, and the output end of the second built-in push rod is connected to the right side of the horizontal docking member. The second built-in push rod laterally drives the horizontal docking member to move along the internal position of the monitoring device body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This guided gas pollutant monitoring device features a guided self-storage structure. This structure pre-processes and controls the quality of the sampled gas inside the pre-extraction pipe. As the internal air pump operates, the first built-in push rod synchronously drives the outer contact limiter downwards. This causes the upper inclined structure of the contact limiter and the magnet of the same magnetic pole to simultaneously contact the horizontal docking piece, allowing it to move laterally under force. The horizontal docking piece, through an internal steel wire rope, drives the sealing docking piece to adaptively unfold along the inside of the pre-extraction pipe, thus connecting the pipe and achieving a protective sampling state with adaptive opening and closing. This enables precise sampling, and, in conjunction with the synchronously linked guided self-storage and guided emission structures, allows the residual gas sample from the previous test to be released quickly and adaptively, avoiding data lag in subsequent tests and ensuring high accuracy and efficiency in the overall pre-processing and detection process.

[0020] Furthermore, during the gas extraction monitoring inside the pre-reserved suction tube, the horizontally displaced connecting piece will drive the integrated upper piston piece to move horizontally in sync. This, in conjunction with the pre-reserved through hole in the connected state and the negative pressure suction state of the pre-reserved suction tube, allows gas to be stored in the gas storage chamber. As the piston piece moves horizontally to contact the pre-reserved piece, the simultaneously pressurized first internal liquid bladder will supply the second internal liquid bladder through the supply hose, making the gas storage chamber self-sealed. After subsequent sampling, the gas is released outward through the pre-reserved through hole by the self-opening and closing of the sealing vertical piece and the reverse return pressure state of the piston piece. This ensures the stable discharge of residual gas samples after a single sampling inside the pre-reserved suction tube, preventing it from affecting the accuracy of subsequent re-detection and processing, and ensuring the accuracy of data monitoring.

[0021] Furthermore, a guided emission structure is provided to release the residual gas stored inside the pre-reserved suction pipe. As the piston moves laterally with the horizontal docking component, it drives the outer fixed connecting rod to move synchronously along the inner side of the monitoring device body. This causes the fixed connecting rod to apply pressure to the contacting guided fitting component and rotate outward. In conjunction with the release of the gas stored in the gas storage cavity, the released gas is guided upward, ensuring the stability and quality of its emission. This further ensures the high efficiency of the device after a single sampling and avoids data lag in the gas mixing state during subsequent sampling and testing, thus improving the practicality of the device.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-10This invention provides the following technical solution: A guided gas pollutant monitoring device, to solve the problem that after a single sampling, some gas samples from the previous sampling are easily retained inside the device, causing a lag in the detection data during subsequent detections, discloses the following: A suction pre-installed pipe 2 is internally connected to the monitoring device body 1; a gas pump is pre-installed inside the monitoring device body 1, and the suction pre-installed pipe 2 is connected to the pre-installed gas pump structure inside the monitoring device body 1 for gas extraction and detection; a driving component is installed inside the monitoring device body 1; a horizontally nested connecting piece 5 is installed on the inner side of the monitoring device body 1; a sealing connecting piece 8 is nested on the inner side of the middle of the monitoring device body 1, and the sealing connecting piece 8 is internally connected to the suction pre-installed pipe 2; a guided self-accumulating gas structure is provided between the suction pre-installed pipe 2 and the monitoring device body 1, and the quality of the sampled gas inside the suction pre-installed pipe 2 is pre-treated and controlled by the guided self-accumulating gas structure; the driving component is a first built-in push rod 3, and the lower end of the first built-in push rod 3 is vertically... The first built-in push rod 3 is connected to the output end of the suction pre-reserved pipe 2, and the output end of the first built-in push rod 3 is connected to the abutment limiting member 4. Magnet docking members 6 are fixedly connected to the outer side of the horizontal docking member 5 and the upper outer side of the abutment limiting member 4. The self-accumulating air structure is equipped with a built-in steel wire rope 7, one end of which is connected to the upper outer side of the horizontal docking member 5, and the middle section of the built-in steel wire rope 7 runs along the inner side of the monitoring device body 1. Simultaneously, the end of the built-in steel wire rope 7 is connected to the outer side of the sealing docking member 8 to form a traction structure. A first spring 9 is fixedly connected to the outer side of the docking part 8, and the first spring 9 is docked with the inner side of the monitoring device body 1; an air storage cavity 11 is opened inside the monitoring device body 1, and a fitting piston 10 is nested inside the air storage cavity 11, and the lower end of the fitting piston 10 is docked with the upper end of the horizontal docking part 5; a reserved through hole 13 is opened on the outer side of the air storage cavity 11, and a second spring 12 is fixedly connected to the inner side of the air storage cavity 11, and the second spring 12 is docked with the outer side of the fitting piston 10.

[0036] The contact limiting member 4 moves downward along the inner side of the suction reserved passage pipe 2 driven by the first built-in push rod 3. The contact limiting member 4, in conjunction with the inclined structure at its upper end and the magnet docking member 6 with the same magnetic pole, pushes the outer horizontal docking member 5 to move laterally. The horizontal docking member 5 drives the sealing docking member 8 to form a traction structure through the built-in steel wire rope 7. The horizontal docking member 5 and the fitting piston member 10 are an integrated structure. The fitting piston member 10 fits and moves along the inner side of the gas storage reserved cavity 11. During the process of gas extraction and sampling, the preset air pump structure inside the monitoring equipment body 1 is first started to extract gas through the suction reserved passage pipe 2. During gas treatment, the first built-in push rod 3 inside the monitoring device body 1 will be activated synchronously through a preset circuit program, thereby driving the output end's contact limit member 4 to move downwards synchronously. This allows the upper inclined structure of the contact limit member 4 and the magnet docking member 6 with the same magnetic pole to simultaneously contact the horizontal docking member 5, causing it to move laterally under force. The horizontal docking member 5 will then drive the sealing docking member 8 to adaptively unfold along the inside of the suction reserved passage 2 through the built-in steel wire rope 7, thereby putting the suction reserved passage 2 into a connected state and realizing an adaptive closed-open protective sampling state, thus enabling precise gas sampling operations. In conjunction with the synchronized self-accumulating gas structure and the guided emission structure, the residual gas sample from the previous test inside the equipment is released adaptively and quickly, avoiding data lag during subsequent tests. During the gas extraction monitoring inside the pre-reserved suction pipe 2, the horizontally displaced connecting piece 5 will drive the integrated upper piston piece 10 to move horizontally in sync. This, combined with the connected pre-reserved through hole 13 and the negative pressure suction state of the pre-reserved suction pipe 2, allows gas to be stored inside the gas storage cavity 11. As the piston piece 10 moves horizontally to contact the gas storage cavity 11, the gas storage process continues. When the reserved part 14 contacts, the built-in first liquid bladder 15, which is under synchronous pressure, will supply the built-in second liquid bladder 17 through the supply hose 16. This causes the built-in second liquid bladder 17 to expand vertically and push the contacting sealing vertical part 18 downward, so that the gas storage reserved cavity 11 in the gas storage state is in a self-sealing state. After subsequent sampling, through the self-opening and closing of the sealing vertical part 18, in conjunction with the reverse return pressure state of the fitting piston part 10, the stored gas is released outward through the reserved through hole 13. This stabilizes the discharge of the residual gas sample after the single sampling inside the reserved through tube 2, preventing it from affecting the accuracy of subsequent re-detection and processing.

[0037] Example 2: Based on Example 1, to address the issue of insufficient accuracy in detection due to the inability to guarantee the overall pretreatment and detection process, a guided emission structure is also disclosed, the specific structure of which is as follows:

[0038] The inner side of the suction reserved pipe 2 is provided with a guide discharge structure, which releases the residual gas stored inside the suction reserved pipe 2.

[0039] The discharge guidance structure is equipped with a retaining element 14, which is nested and connected to the inner side of the gas storage cavity 11. A built-in first liquid bladder 15 is bonded and connected inside the monitoring device body 1, and the outer side of the built-in first liquid bladder 15 is connected to the outer side of the retaining element 14. A supply hose 16 is threaded through the outer side of the built-in first liquid bladder 15 and runs along the interior of the monitoring device body 1. A sealing vertical element 18 is nested and installed inside the reserved through hole 13, and a built-in second liquid bladder 17 is bonded and connected to the upper end of the sealing vertical element 18. The built-in second liquid bladder 17 is internally connected to the monitoring device body 1, and the upper end of the built-in second liquid bladder 17 is internally connected to the end of the supply hose 16. A fixed connecting rod 19 is fixedly connected to the outer side of the fitting piston 10, and the fixed connecting rod 19 passes through the interior of the monitoring device body 1. A guide fitting member 20 is rotatably connected to the inner wall of the suction pre-reserved tube 2, and the inner position of the guide fitting member 20 corresponds to the outer position of the fixed connecting rod 19. A third spring 21 is fixedly connected to the outer side of the guide fitting member 20, and the third spring 21 is connected to the suction pre-reserved tube 2. The inner walls of the retaining pipe 2 are connected to each other. During the lateral movement of the piston 10 along the inner side of the gas storage cavity 11, it simultaneously applies pressure to the contacting retaining member 14, and the contacting retaining member 14 presses against the inner built-in first liquid bladder 15. The built-in first liquid bladder 15 supplies the working fluid to the inside of the built-in second liquid bladder 17 through the supply hose 16, and the vertical expansion of the built-in second liquid bladder 17 pushes the contacting sealing vertical member 18 downward. During the lateral movement of the piston 10, it drives the outer fixed connecting rod 19 to move synchronously, and the fixed connecting rod 19 presses against the contacting piston 10. The guide fitting 20 is pressed outward and rotated. The guide fitting 20 forms an elastic support structure with the inner wall of the suction reserved passage 2 through the third spring 21. During the process of the fitting piston 10 moving laterally with the horizontal docking part 5, it will drive the outer fixed connecting rod 19 to move synchronously along the inner side of the monitoring equipment body 1, so that the fixed connecting rod 19 presses outward and rotates the contacting guide fitting 20. In turn, in conjunction with the release of the gas stored in the gas storage reserved cavity 11, the released gas is guided upward, ensuring the stability and quality of its emission.

[0040] Example 3: Please refer to Figures 3-11 Based on Embodiment 1, another implementation of the driving component is also disclosed, the specific structure of which is as follows:

[0041] The driving component is a second built-in push rod 22, which is laterally connected to the inside of the monitoring device body 1. The output end of the second built-in push rod 22 is connected to the right side of the horizontal docking part 5. The second built-in push rod 22 laterally drives the horizontal docking part 5 to move along the internal position of the monitoring device body 1. Thus, the horizontally moving horizontal docking part 5, in conjunction with the subsequent synchronously linked guiding self-accumulation structure and guiding emission structure, allows the residual gas sample left inside the device to be released adaptively and quickly, avoiding the lag in detection data during subsequent detection.
