Description

Technical Field

[0001] This invention belongs to the field of gas detection technology, specifically a hazardous gas detection device for gas pipeline corridors in high-rise buildings. Background Technology

[0002] Gas pipeline corridors are underground or above-ground enclosed infrastructures used for the centralized laying, management and maintenance of gas pipelines. Essentially, they are "dedicated channels" for gas transmission. By integrating scattered gas pipelines into a unified space, they can achieve efficient control, safety protection and convenient operation and maintenance of the gas transmission system. They are a core component of the urban gas supply network and are widely used, especially in high-rise buildings.

[0003] To prevent gas leaks from causing explosions, poisoning, and other fatal dangers, and to ensure the safety of surrounding buildings and personnel, it is necessary to detect the gas in the gas pipeline corridor. However, existing hazardous gas detection devices in high-rise building gas pipeline corridors have limitations: the detection instruments are usually fixed in a single position by expansion bolts and other connectors, and can only detect the gas around themselves, making it difficult to cover the detection needs of different locations and heights. This limitation not only narrows the detection range of the device, but also reduces the amount of test samples collected. Insufficient sample size leads to weak data support, ultimately reducing detection accuracy and further exacerbating the limitations of the device. Summary of the Invention

[0014] Preferably, a main valve is installed at the output end of the corrugated square tube; an auxiliary valve is provided at the top of the T-shaped pipe; and a filter plate is also installed at the top of the T-shaped pipe, positioned above the auxiliary valve.

[0015] The beneficial effects that can be achieved by the above embodiments of the present invention include: (1) By using frequency-controlled positioning devices, the gas sensor can detect gas at different positions and heights in the pipe gallery, avoiding blind spots in the detection work that would affect the detection accuracy of the device. At the same time, it also avoids the gas sensor being able to detect only the gas around itself, allowing the gas sensor to cover the detection needs at different positions and heights during use, thus improving the detection range of the device. It also further increases the amount of sample collected, avoiding insufficient sample volume leading to weak detection data support, thereby improving the detection accuracy of the device and reducing the limitations of the device during detection. (2) The anti-skew component is used to monitor the movement of the gas sensor during lateral movement. At the same time, it monitors whether the vertical movement is offset when the gas sensor is adjusted to different heights during lateral movement. This is to improve the movement stability of the gas sensor when adjusting its position and avoid the gas sensor from shifting when adjusting the detection position, thus affecting its performance. When the gas sensor moves vertically during lateral movement to control the detection height, or moves only laterally, the anti-skew plate used to monitor whether the position of the gas sensor is deviated is in contact with the positioning wheel in a reciprocating manner. This indirect detection avoids the two from being in contact for a long time, which would lead to increased wear. It also avoids the need for frequent calibration due to prolonged contact between the two. Long-term monitoring accuracy is more stable. While reducing the calibration frequency, the two anti-skew plates that move back and forth relative to each other are used to squeeze the gas between them. This causes the dust discharged by the gas generator to be blown away from the gas sensor by the squeezed gas, further reducing the limitations of the device during use. (3) The gas cleaner is used to clean the dust or impurities adhering to the gas sensor detection end, so as to avoid the gas sensor adsorbing too many impurities or dust when collecting gas during long-term use in the pipe gallery, which affects the efficiency of sample collection. This improves the performance and detection accuracy of the gas sensor, and also improves the detection efficiency of the device. After the corrugated square tube blows away the dust or impurities adhering to the gas sensor detection end, the gas squeezed by the relative movement of the two anti-deviation plates is used to displace the surrounding gas, so as to avoid these impurities being dispersed around the gas sensor and affecting its normal use. In other words, the reciprocating movement of the two anti-deviation plates can also actively displace the dust and other impurities floating in the gas, so as to avoid the gas sensor sampling impurities at the same time and reducing its service life, thus further improving the performance of the device. (4) The fixed loading and unloading module makes the loading and unloading operation of the device convenient and quick when the gas sensor is used to detect in the gas pipeline corridor. It can be completed without the aid of any tools, avoiding the need to use or rely on tools to complete the loading and unloading operation when the gas sensor is used to detect harmful gases in the gas pipeline corridor. This reduces the limitations of the device when it is used and improves the overall effect of the gas sensor when it is used in the gas pipeline corridor. (5) The pressure and resistance mechanism is used to limit the locking block while continuously applying pressure to it, so as to avoid the elastic locking unit from dislodging due to insufficient strength when clamping the gas sensor. At the same time, it avoids the gas sensor from dislodging or displacement due to non-human factors during the clamping process, reducing the limitations of the device in use. Meanwhile, the contact and pressure of the locking block are reciprocating, which strengthens the clamping effect of the elastic locking unit on the gas sensor. While ensuring the clamping strength, it avoids the spring on the elastic locking unit from being in a continuous pressure and long-term buffer state, which leads to performance decay. The durability of the spring is greatly improved. At the same time, when the pressure is released, the gas sensor has time to release internal stress, avoiding deformation and damage caused by long-term high-strength clamping. It is worth mentioning that releasing the pressure on the locking block is not the same as releasing the limiting state when clamping the gas sensor. This further improves the clamping effect of the elastic locking unit on the gas sensor, and at the same time improves the service life of the gas sensor, so that the gas detection effect of the device in the pipe gallery and the use effect of the device itself are improved. (6) The elastic locking unit makes it convenient and quick to install or remove the gas sensor from the positioning connecting cylinder without the need for any tools, which reduces the limitations of the device during use. At the same time, the ease of removing and installing the gas sensor also allows for quick replacement or maintenance, so that the appropriate gas sensor can be used according to different detection needs, which improves the use and detection effect of the device.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Implementation examples, by Figures 1 to 12The present invention includes an inner wall of a pipe gallery and a gas sensor 1. A positioning and unloading module is provided on the inner wall of the pipe gallery for installing or removing the gas sensor 1 from the inner wall. The positioning and unloading module includes a transverse slide rail 2 located on the inner wall of the pipe gallery; a positioning block 3 is provided on the side of the transverse slide rail 2 near the inner wall; a positioning groove 4 is provided on the inner wall of the pipe gallery; the positioning groove 4 and the positioning block 3 are engaged, and when they are in contact, the transverse slide rail 2 is in contact with the inner wall of the pipe gallery; a positioning base 24 is connected to both sides of the transverse slide rail 2; a positioning screw 25 is installed on the positioning base 24, and a power source 26 is connected to the positioning screw 25; the positioning screw 25 has two opposite threaded areas, which are symmetrically arranged about the positioning base 24 as an axis of symmetry; and a positioning block 2. 7; Two retaining blocks 27 are threadedly connected to two threaded areas respectively; a retaining cylinder 28 is installed on the retaining base 24, and the two ends of the retaining cylinder 28 pass through the opposite sides of the two retaining blocks 27 respectively, and the two are slidably engaged; an auxiliary square groove 29 is set on the side of the retaining block 3 near the retaining base 24; a loading and unloading cross plate 30 is installed on each of the two retaining blocks 27, located in the auxiliary square groove 29; a loading and unloading slot 31 is set at the top and bottom of the retaining groove 4; loading and unloading inserts 32 are installed on the opposite sides of the two loading and unloading cross plates 30; when the retaining block 3 is fitted in the retaining groove 4, the rotation of the retaining screw 25 causes the two loading and unloading cross plates 30 to move in opposite directions, so that the loading and unloading inserts 32 on them pass through the auxiliary square groove 29 on the retaining block 3 and connect with the loading and unloading slot 31; When in use, the device needs to be installed inside a gas pipeline corridor. The gas sensor 1, used to detect harmful gases within the corridor, is mounted on this entire unit, meaning it also needs to be installed inside the corridor. A retaining spacer groove 4 is pre-cut into the inner wall of the corridor. By aligning the retaining spacer block 3 on the transverse slide rail 2 with the retaining spacer groove 4 and moving it, the retaining spacer block 3 enters the retaining spacer groove 4, and the two become aligned. At this point, sensor signals can be used to automatically determine the connection status between the retaining spacer groove 4 and the retaining spacer block 3. Once they are properly aligned, the signal is automatically transmitted to the control center, which then sends a start signal to the power source. At position 26, the mechanism automatically starts without human interference, causing the retaining screw 25 to rotate. This causes the two retaining blocks 27 to move in opposite directions at the retaining cylinder 28, which in turn causes the two loading / unloading cross plates 30 to move in opposite directions within the auxiliary square groove 29. The loading / unloading inserts 32 on these plates are initially positioned within the auxiliary square groove 29. As the two loading / unloading inserts 32 move in opposite directions within the auxiliary square groove 29, they pass through the auxiliary square groove 29 on the retaining rectangular block 3 and connect with the loading / unloading slot 31, thus limiting the retaining rectangular block 3 to its current position. The connection between the retaining rectangular block 3 and the retaining rectangular groove 4 limits the left, right, up, and down sides of the retaining rectangular block 3. By using the loading and unloading plug 32, the front and rear of the retaining block 3 are also limited, thereby fixing the retaining block 3 in all directions. At the same time, the transverse slide rail 2 on it is fixed to the inner wall of the pipe rack. At this time, the transverse slide rail 2 is in contact with the inner wall of the pipe rack, thus fixing the transverse slide rail 2 on the gas sensor 1 to the inner wall of the pipe rack for use. When disassembling, the retaining screw 25 is reversed so that the loading and unloading plug 32 is no longer located in the auxiliary square groove 29. This makes the loading and unloading process of the device convenient and quick when the gas sensor 1 is used in the gas pipe rack, and it can be completed without the aid of any tools, avoiding the need for gas sensors in the gas pipe rack. When the gas sensor 1 detects harmful gases, it requires the use of tools to complete the loading and unloading operation, which reduces the limitations of the device during use and improves the overall performance of the gas sensor 1 when used in the gas pipeline corridor. It is worth mentioning that the fixation moment grooves 4 at different heights can be provided on the inner wall of the pipeline corridor, so that the gas sensor 1 can be used as the initial position for detection at different heights in the gas pipeline corridor. At the same time, the fixation moment grooves 4 can be set with different inclinations. When used in conjunction with the frequency-controlled position device, the working range of the gas sensor 1 is further improved, reducing the limitations of the device during detection and improving the detection effect and accuracy of the device.

[0020] In this embodiment, a frequency-controlled positioning device is provided on the transverse slide rail 2 to adjust the working position of the gas sensor 1. The frequency-controlled positioning device includes a transverse slider 5, which is installed on the transverse slide rail 2 and the two slide in cooperation; a vertical slide rail 6, which is connected to the side of the transverse slider 5 away from the inner wall of the pipe gallery; the vertical slide rail 6 and the transverse slide rail 2 are arranged perpendicularly; a vertical slider 7 is slidably connected to the vertical slide rail 6; a positioning connecting cylinder 8 is installed on the side of the vertical slider 7 away from the inner wall of the pipe gallery; the gas sensor 1 is fitted and connected inside the positioning connecting cylinder 8, and the detection end of the gas sensor 1 faces away from the inner wall of the pipe gallery. During operation, the device uses gas sensor 1 to detect gas within the gas pipeline corridor, determining the presence of harmful gases. Gas sensor 1 is mounted on vertical slider 7 via positioning connecting cylinder 8. By controlling vertical slider 7 to move along vertical slide rail 6, gas sensor 1 can move vertically, allowing it to detect gas at different heights within the corridor. Vertical slide rail 6 is mounted on horizontal slider 5. By controlling horizontal slider 5 to move at its upper limit along horizontal slide rail 2, gas sensor 1 can move horizontally, detecting gas at different horizontal positions at the same height, covering a planar area and detecting each point individually. This can be used to detect sources of harmful gases. Simultaneously, the above operations allow gas sensor 1 to detect gas at different locations and heights within the corridor. The gas sensor 1 is designed to detect gases in a way that avoids blind spots that could affect the accuracy of the device. It also prevents the gas sensor from being limited to its own surroundings, allowing it to cover detection needs at different locations and heights, thus increasing the detection range of the device. Furthermore, it increases the amount of sample collected, preventing insufficient sample volume from leading to weak data support and improving the accuracy of the device, thereby reducing its limitations. The gas sensor 1 is fixed to the inner wall of the pipe gallery via a lateral slide rail 2 and a fixed mounting / unmounting module. This integrated design allows for convenient installation of the gas sensor 1 and lateral slide rail 2 in different pipe galleries, preventing the gas sensor 1 from becoming dislodged from the lateral slide rail 2 and affecting the device's detection capabilities, further reducing the limitations of the device's use.

[0021] In this embodiment, the positioning connecting cylinder 8 is provided with an elastic locking unit for fixing the gas sensor 1 inside the positioning connecting cylinder 8. The elastic locking unit includes a locking square post 9; two locking square posts 9 are symmetrically connected to opposite outer walls of the positioning connecting cylinder 8; a locking block 33 is slidably connected to the locking square post 9; a locking limiting plate is connected to one end of the locking square post 9 away from the positioning connecting cylinder 8; a locking spring 34 is sleeved on the locking square post 9; one end of the locking spring 34 is fixedly connected to the locking limiting plate, and the other end is fixedly connected to the locking block 33; a locking horizontal plate 35 is connected to the locking block 33; the locking horizontal plate 35 is located away from the locking square post 9. A locking cylinder 36 is connected through one side of the gas sensor 1 and slides in cooperation with the locking plate 35. A locking limit plate is connected to one end of the locking cylinder 36 away from the gas sensor 1, and a locking arc plate 37 is connected to the other end. The outer wall of the gas sensor 1 is located within the moving path of the locking arc plate 37. Two locking arc plates 37 at two locking square pillars 9 contact the outer wall of the gas sensor 1 for clamping and setting it. A locking spring 38 is sleeved on the locking cylinder 36. One end of the locking spring 38 is fixedly connected to the locking limit plate, and the other end is fixedly connected to the locking plate 35. The strength of the locking spring 34 is greater than that of the locking spring 38. When the device is in use, gas sensor 1 is used to detect the gas in the pipe gallery. Gas sensor 1 needs to be installed on the transverse slide rail 2. By pulling the locking block 33 outwards, it moves to the upper limit of the locking column 9, causing the locking spring 34 to be in a buffer state. This causes the two locking blocks 33 to move away from each other, which in turn moves the locking horizontal plate 35. The two locking horizontal plates 35 then move away from each other, causing the locking arc plate 37 to move away from the positioning connecting cylinder 8 under the action of the locking cylinder 36 and the locking spring 38. At this point, the gas sensor 1 required for detection is placed... The gas sensor 1 is inserted into the positioning connecting cylinder 8. It is worth mentioning that the above operation method can also be used to disassemble the gas sensor 1. After the gas sensor 1 is in the positioning connecting cylinder 8, the locking block 33 is released. The locking block 33 is reset and moved by the reset of the locking spring 34, which causes the locking horizontal plate 35 on it to reset and move. Then, under the action of the locking cylinder 36 and the locking spring 38, the locking arc plate 37 is reset and moved, so that the two locking arc plates 37 move relative to each other and come into contact with the gas sensor 1, thus clamping and fixing the gas sensor 1 in the positioning connecting cylinder 8, thereby completing the installation of the gas sensor 1. Furthermore, the installation and removal of the gas sensor 1 from the positioning connecting cylinder 8 is convenient and quick, requiring no tools and reducing limitations in the use of the device. The ease of installation and removal of the gas sensor 1 also allows for quick replacement or maintenance, enabling the use of appropriate gas sensors 1 according to different detection needs, thus improving the device's usability and detection performance. It is worth noting that when the locking arc plate 37 contacts the outer wall of the gas sensor 1, the locking spring 34 has not yet fully reset, meaning the locking block 33 must continue to move. This is because the strength of the locking spring 34 is greater than the locking... Spring 38 causes the locking block 33 to continue moving, which in turn causes the locking plate 35 on the locking block 33 to move at the locking cylinder 36 on the locking arc plate 37, so that the locking spring 38 is in a buffer state, thereby increasing the contact strength between the locking arc plate 37 and the gas sensor 1, preventing dislocation during the contact process and affecting the normal use of the gas sensor 1, improving the performance of the gas sensor 1, and improving the clamping effect of the gas sensor 1, thus improving the stability of the gas sensor 1 during use, and further improving the gas detection effect of the gas sensor 1.

[0022] In this embodiment, the anti-misalignment component is installed on the horizontal slider 5 to prevent the gas sensor 1 from shifting position during adjustment. The anti-misalignment component includes a reset rack 10 connected to the inner wall of the pipe gallery; a reset gear 11 installed on the top of the horizontal slider 5, with the reset rack 10 positioned along the movement path of the reset gear 11; when the horizontal slide rail 2 is in contact with the inner wall of the pipe gallery, the reset rack 10 and the reset gear 11 mesh; a double-ended cam 12 connected to the top of the reset gear 11; and a reset base 13.

Inside the cylinder 18; one end of the compression spring 21 is fixedly connected to the repeating square cylinder 18, and the other end is fixedly connected to the repeating square column 19; a pressure sensor 22 is provided inside the repeating square cylinder 18, which is connected to the compression spring 21; a positioning square seat is installed on both sides of the vertical slider 7; a positioning wheel 23 is provided inside the positioning square seat; the anti-deviation plate 20 is initially in contact with the positioning wheel 23, and when the double-ended cam 12 rotates and contacts the repeating horizontal block 15, the anti-deviation plate 20 moves away from the positioning wheel 23; After the transverse slide rail 2 is installed on the inner wall of the pipe gallery, the reset gear 11 on the transverse slider 5 contacts and meshes with the reset rack 10. When the transverse slider 5 drives the gas sensor 1 to move laterally to control it to detect gas at different horizontal positions at the same height, the reset gear 11 on the transverse slider 5 rotates during movement, causing the double-ended cam 12 to rotate. During rotation, the two ends of the cam continuously and synchronously contact the two repeating horizontal blocks 15, causing the two repeating horizontal blocks 15 to move in opposite directions. This allows them to move at the upper limit of the repeating base 13 via the repeating cylinder 14, keeping the repeating spring 16 in a buffered state. When the cams at both ends of the double-ended cam 12 no longer synchronously contact the two repeating horizontal blocks 15 during rotation, it indicates that the repeating horizontal blocks 15 are released. The applied force 5 causes the reciprocating spring 16 to reset and move the reciprocating horizontal block 15, causing the two reciprocating horizontal blocks 15 to move relative to each other. This, in turn, causes the double-ended cam 12 to rotate continuously, keeping the two reciprocating horizontal blocks 15 in a state of constant opposite-direction and relative movement. This, in turn, causes the two reciprocating horizontal plates 17 to move relative to each other. When the two reciprocating horizontal plates 17 move relative to each other, under the action of the reciprocating square tube 18, the reciprocating square column 19, and the compression spring 21, they cause the anti-deviation plate 20 to move closer to the gas sensor 1 and contact the positioning wheel 23. This means that during the reciprocating movement, the two anti-deviation plates 20 simultaneously contact the positioning wheels 23 on both sides of the vertical slider 7, monitoring the movement of the gas sensor 1 during lateral movement. During the horizontal movement of gas sensor 1, the vertical movement is monitored to ensure stability and prevent deviations that could affect its performance. When the gas sensor 1 deviates vertically, the two anti-deviation plates 20 cannot simultaneously contact the positioning wheels 23, causing deformation of one anti-deviation plate 20. This deformation of the compression spring 21 is then promptly transmitted to the control center via the pressure sensor 22 to alert the operator. This continuous monitoring of the gas sensor 1's vertical movement during horizontal movement prevents it from becoming stuck in vertical motion for extended periods. If a deviation occurs, the detection position may deviate too much from the preset value, affecting the detection results. Simultaneously, since the initial position of the anti-deviation plate 20 is in contact with the positioning wheel 23, when the gas sensor 1 is not moved laterally and is only used to adjust its detection height, the vertical slider 7 on the gas sensor 1 will move at the upper limit of the anti-deviation plate 20 via the positioning wheel 23, preventing the gas sensor 1 from shaking or deviating during movement. Furthermore, if a vertical deviation occurs, the pressure sensor 22 will promptly alert the operator. Additionally, the buffering force provided by the compression spring 21 can reduce the impact force caused by the shaking of the gas sensor 1 during vertical movement, further improving the performance of the gas sensor 1 and enhancing the detection effect of the device.It is worth mentioning that when the gas sensor 1 moves horizontally, it simultaneously moves vertically to control the detection height, or when it moves horizontally alone, the contact between the anti-deviation plate 20, which monitors whether the position of the gas sensor 1 has deviated, and the positioning wheel 23 is reciprocating. This indirect detection avoids prolonged contact between the two, which would lead to accelerated wear. It also avoids the need for frequent calibration due to prolonged contact, resulting in more stable long-term monitoring accuracy. While reducing the calibration frequency, the reciprocating relative movement of the two anti-deviation plates 20 compresses the gas between them, causing the dust discharged from the gas generator to be blown away from the gas sensor 1 by the compressed gas, further reducing the limitations of the device in use.

[0023] In this embodiment, a pressure-applying and resistance-applying mechanism is provided on the positioning base. The pressure-applying and resistance-applying mechanism includes a pressure base 39, which is installed on the side of the positioning base away from the inner wall of the pipe gallery; a pressure cylinder 40, which is connected through the pressure base 39 on the side away from the positioning connecting cylinder 8, and the pressure cylinder 40 and the pressure base 39 are slidably fitted together; a first contact block 41 is connected to one end of the pressure cylinder 40 away from the positioning connecting cylinder 8, and a pressure block 42 is connected to the other end; a pressure spring 43 is sleeved on the pressure cylinder 40; one end of the pressure spring 43 is fixedly connected to the first contact block 41, and the other end is fixedly connected to the pressure base 39. Connection; guide groove 44, set on the side of the repeating horizontal plate 17 away from the inner wall of the pipe gallery, and set parallel to the vertical slide rail 6; drive slider 45, slidably connected in the guide groove 44; L-shaped column 46 is installed on the drive slider 45; second contact block 47 is installed on the end of the L-shaped column 46 facing the positioning connecting cylinder 8; when the side wall of the double-ended cam 12 contacts the repeating horizontal block 15, the locking block 33 is located in the moving path of the pressure block 42, and the first contact block 41 is located in the moving path of the second contact block 47; displacement sensor 48, all connected to the second contact block 47 and the first contact block 41; When the two reciprocating horizontal plates 17 move back and forth relative to each other, the L-shaped column 46 on it will continuously contact the first contact block 41 on the pressure cylinder 40 through the second contact block 47. When the two contact, the pressure cylinder 40 on the first contact block 41 will move to a limited position at the pressure base 39, so that the pressure spring 43 is in a buffer state. Then, the pressure block 42 on the pressure cylinder 40 will contact the locking block 33, which limits the locking block 33 while continuously applying pressure to it. This prevents the elastic locking unit from dislodging due to insufficient strength when clamping and fixing the gas sensor 1, and also prevents gas transmission. During the clamping process, sensor 1 may become dislodged or shifted due to non-human factors, reducing the limitations of the device in use. Simultaneously, when the second contact block 47 is not in contact with the first contact block 41, it indicates that the two reciprocating horizontal plates 17 are in a state of opposite movement. This releases the pressure on the first contact block 41, allowing it to be reset by the pressure spring 43, which in turn moves the pressure block 42 back to its original position, preventing it from contacting the locking block 33. This indicates that the contact and pressure on the locking block 33 are reciprocating, strengthening the clamping effect of the elastic locking unit on the gas sensor 1. This ensures clamping strength while preventing the spring on the elastic locking unit from being under continuous pressure. The buffering state leads to performance degradation, but significantly improves the durability of the spring. Simultaneously, releasing the pressure allows gas sensor 1 time to release internal stress, preventing deformation and damage caused by prolonged high-intensity clamping. It's worth noting that releasing the pressure on locking block 33 is not equivalent to releasing the limiting state while clamping gas sensor 1. This further improves the clamping effect of the elastic locking unit on gas sensor 1, extending its service life and enhancing the gas detection performance and overall usability of the device within the pipe gallery. It's also worth mentioning that when gas sensor 1 moves vertically... Simultaneously, the first contact block 41 will move, causing the displacement sensor 48 on it to send a signal to the control center. The control center will then control the drive slider 45 to move within the guide groove 44 based on the start signal sent by the displacement sensor 48 on the second contact block 47. This will drive the L-shaped column 46 on the drive slider 45 to move, ensuring that the second contact block 47 is always at the same height as the first contact block 41. This prevents the pressure and resistance mechanism and the gas purification device from malfunctioning due to changes in the height of the second contact block 47 and the first contact block 41 caused by the vertical movement of the gas sensor 1, thus reducing the limitations of the device during use.

[0024] In this embodiment, a gas generator is installed on the positioning connecting cylinder 8. The gas generator includes a braking square column 49, which is installed on the pressure cylinder 40 with its end facing the positioning connecting cylinder 8; a T-shaped pipe 50, which is installed on the positioning connecting cylinder 8; the two input ends of the T-shaped pipe 50 are respectively facing the two braking square columns 49 located on both sides of the positioning connecting cylinder 8; the two braking square columns 49 are respectively located inside the two input ends of the T-shaped pipe 50, and the two are in sliding fit; the output end of the T-shaped pipe 50 is away from the inner wall of the pipe gallery and is equipped with a corrugated square tube 51; the output end of the corrugated square tube 51 faces the detection end of the gas sensor 1; a main valve is installed at the output end of the corrugated square tube 51; an auxiliary valve is provided at the top of the T-shaped pipe 50; a filter plate 52 is also installed at the top of the T-shaped pipe 50, located above the auxiliary valve. As the two reciprocating horizontal plates 17 move back and forth, the pressure cylinder 40's brake column 49 also reciprocates within the input end of the T-shaped pipe 50 via the pressure and resistance mechanism. When the two brake columns 49 at both input ends of the T-shaped pipe 50 move synchronously relative to each other as the two reciprocating horizontal plates 17 move relative to each other, the control center closes the auxiliary valve and opens the main valve, causing the gas within the input ends of the T-shaped pipe 50 to be squeezed to the output end. This gas then acts on the detection end of the gas sensor 1 through the corrugated square tube 51 for cleaning. Dust adhering to the detection end of gas sensor 1; when the two reciprocating horizontal plates 17 move in opposite directions, causing the two braking columns 49 to move in opposite directions at the input ends on both sides of the T-shaped pipe 50, the main valve is closed while the auxiliary valve is opened, allowing outside gas to be drawn into the T-shaped pipe 50 and filtered through the filter plate 52 to remove impurities from the gas, preventing impurities from entering the T-shaped pipe 50 and the corrugated square tube 51 and affecting their performance; the reciprocating movement of the braking columns 49 causes the corrugated square tube 51 to continuously spray gas to the gas sensor. The detection end 1 is used to continuously clean dust or impurities adhering to the detection end of the gas sensor 1. This prevents the gas sensor 1 from absorbing too much impurities or dust during long-term use in the pipe gallery, which would affect the efficiency of sample collection. This improves the performance and detection accuracy of the gas sensor 1, thereby increasing the detection efficiency of the device. At the same time, it avoids the need for manual cleaning of impurities adhering to the detection end of the gas sensor 1, reducing the workload of personnel and reducing the limitations of the device during detection. After the corrugated square tube 51 blows away the dust or impurities adhering to the detection end of the gas sensor 1, the gas squeezed by the relative movement of the two anti-deviation plates 20 is used to displace the surrounding gas, preventing these impurities from dispersing around the gas sensor 1 and affecting its normal use. In other words, the reciprocating movement of the two anti-deviation plates 20 can also actively displace dust and other impurities floating in the gas, preventing the gas sensor 1 from sampling impurities simultaneously and reducing its service life, thus further improving the performance of the device.
