Abstract

This invention belongs to the field of gas detection technology and provides a gas detection device that prevents particles from clogging the perforations through a four-sided unblocking mechanism and removes particles from the sensor through a sensor cleaning mechanism. It particularly relates to an anti-interference combustible gas detection device. The invention mainly consists of a cover, horizontal and vertical perforations, a gas sensor, a four-sided unblocking mechanism, and a sensor cleaning mechanism. The four-sided unblocking mechanism uses a motor to drive components such as a square plate, a right-angle extension plate, and a top block, causing the unblocking block to periodically unclog the horizontal and vertical perforations, preventing particle blockage and ensuring smooth gas entry. The sensor cleaning mechanism uses a scraper and a retractable air jet to remove particles from the sensor surface, especially effectively clearing blockages caused by gas particle accumulation in the horizontal and vertical perforations. This allows combustible gas to enter the device unimpeded through the perforations, preventing the sensitive area of ​​the sensor from being covered or contaminated.

Description

Technical Field

[0001] This invention belongs to the field of gas detection technology and provides a gas detection device that prevents particles from clogging and perforating the sensor through a four-sided unblocking mechanism and removes particles from the sensor through a sensor cleaning mechanism. In particular, it relates to an anti-interference combustible gas detection device. Background Technology

[0002] Combustible gases are widely present in industrial production and daily life, such as natural gas, coal gas, and liquefied petroleum gas. Once these combustible gases leak and mix with air to reach a certain concentration, they may cause serious accidents such as explosions and fires when they encounter a source of ignition, posing a huge threat to the safety of people's lives and property. Therefore, it is crucial to accurately and timely detect combustible gas leaks, and combustible gas detection devices have become important equipment to ensure safety.

[0003] In practical applications, combustible gas detection devices are subject to various interference factors. Electromagnetic interference in industrial environments may come from nearby large motors, transformers, high-frequency equipment, etc. These devices generate strong electromagnetic fields during operation, interfering with the electronic components and signal transmission of the detection device, leading to measurement errors or even false alarms. Changes in ambient temperature and humidity also affect the detection results. The sensor performance of combustible gas detectors changes with temperature and humidity. For example, in high-temperature environments, the sensitivity of the sensor may decrease, while in high-humidity environments, signal drift and other problems may occur. In addition, dust, smoke, and other impurities may also be adsorbed on the sensor surface, affecting its adsorption and reaction to combustible gases, thereby reducing the accuracy of detection.

[0004] Therefore, in the field of combustible gas detection, it is necessary to continuously explore and develop more effective technologies to prevent gas particle interference, so as to improve the stability and reliability of detection devices and ensure that they can accurately detect combustible gas leaks in various complex environments.

[0016] As a preferred embodiment of the present invention, the surface of the dredging block is provided with an oleophobic and hydrophobic coating to prevent gas particles from adhering and to avoid affecting the perforation and dredging effect due to particle accumulation.

[0017] As a preferred embodiment of the present invention, the horizontal and vertical through holes of the cover are provided with a one-way structure to prevent water mist from entering the combustible gas.

This allows combustible gas to enter the device through the through holes without obstruction, maintaining a stable and efficient gas flow path. Compared with traditional detection devices, this device significantly improves the timeliness and reliability of detection in high particle concentration environments.

[0022] The adhesion of gas particles to the sensor surface can seriously affect its detection of combustible gases. The oleophobic and hydrophobic coating of this device effectively prevents particles from adhering to the guide block and the sensor surface, avoiding the sensor's sensitive area from being covered or contaminated.

[0023] Traditional detection devices often require frequent maintenance due to gas particle interference, such as cleaning sensors and unclogging air inlets. However, this device, with its effective particle protection measures, greatly reduces maintenance needs, saving a lot of manpower and material costs, increasing the continuous working time of the detection device, reducing downtime caused by maintenance, and improving production efficiency.

[0024] Continuous gas particle erosion can damage the internal structure and components of the detection device, such as causing blockages and perforations leading to abnormal internal pressure, and particle adhesion causing sensor corrosion. This device protects the key components of the device by preventing gas particle interference, thereby significantly extending the service life of the entire combustible gas detection device and reducing equipment replacement costs.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] The four-sided unblocking mechanism 5 includes a square plate 501, a right-angle extension plate 1 502, a right-angle extension plate 2 503, a right-angle extension plate 3 504, a right-angle extension plate 4 505, a sealing plate 1 506, a guide block 1 507, a sealing plate 2 508, a guide block 2 509, a sealing plate 3 510, a guide block 3 511, a sealing plate 4 512, a guide block 4 513, a top block 1 514, a fixing pin 1 515, a top block 2 516, a driven shaft 517, a top block 3 518, a top block 4 519, a U-shaped seat 520, a motor 521, an insertion rod 522, a fixing pin 2 523, and a well-shaped four-end telescopic device 524.

[0036] Motor 521 is installed at the center of the inner wall of housing 1. One end of driven shaft 517 is fixedly connected to the output end of motor 521. Square plate 501 is fixedly inserted into the other end of driven shaft 517. Four fixing pins 1 515 are fixed to the four corners of square plate 501. One end of right angle extension plate 1 502, right angle extension plate 2 503, right angle extension plate 3 504 and right angle extension plate 4 505 are rotatably mounted on the four fixing pins 1 515 in sequence. The four fixing pins 2 523 are fixed to the four corners of square plate 501. The bottoms of top blocks 1 514, 2 516, 3 518 and 4 519 are fixed in sequence. The other ends of right angle extension plates 1 502, 2 503, 3 504 and 4 505 are rotatably mounted on four fixing pins 2 523 in sequence. The four U-shaped seats 520 are fixed in sequence to the bottoms of top blocks 1 514, 2 516, 3 518 and 4 519, and are set at the same horizontal line as the four fixing pins 2 523.

[0037] The well-shaped four-end telescopic device 524 is installed between the square plate 501 and the motor 521. The well-shaped four-end telescopic device 524 is composed of two sets of telescopic rods that intersect perpendicularly. Both sets of telescopic rods have outputs at both ends. Each output end is fixed with a collar. Four insert rods 522 are fixedly inserted into the collar and pass through the U-shaped seat 520.

[0038] Sealing plates 1 (506), 2 (508), 3 (510), and 4 (512) are sequentially fixed to one end of top blocks 1 (514), 2 (516), 3 (518), and 4 (519). Multiple diversion blocks 1 (507), 2 (509), 3 (511), and 4 (513) are sequentially fixed to sealing plates 1 (506), 2 (508), 3 (510), and 4 (512). Diversion blocks 1 (507), 2 (509), 3 (511), and 4 (513) are sequentially fixed to sealing plates 1 (506), 2 (508), 3 (510), and 4 (512). 509, 511, and 513 are all distributed in an array at equal intervals. The number of 507 and 511 corresponds to the number of transverse holes 2, and the number of 509 and 513 corresponds to the number of vertical holes 3. The length of 507 and 511 is longer than the depth of the transverse holes 2, and the length of 509 and 513 is longer than the depth of the vertical holes 3.

[0039] The sensor cleaning mechanism 6 includes a first scraper rod 601, a first telescopic jet rod 602, a second scraper rod 603, a second telescopic jet rod 604, a third scraper rod 605, a third telescopic jet rod 606, a fourth scraper rod 607, and a fourth telescopic jet rod 608.

[0040] Scraper bar 1 601 and telescopic jet bar 1 602 form one group; scraper bar 2 603 and telescopic jet bar 2 604 form one group; scraper bar 3 605 and telescopic jet bar 3 606 form one group; scraper bar 4 607 and telescopic jet bar 4 608 form one group. The four groups are fixedly mounted on the four insert bars 522, with each group being mounted diagonally on the insert bars 522.

[0041] There are four gas sensors 4, which are installed at the four corners of the inner wall of the enclosure 1.

[0042] Among them, motor 521 drives the output shaft to rotate counterclockwise, which in turn drives the driven shaft 517 to rotate counterclockwise. The driven shaft 517 drives the square plate 501 to rotate counterclockwise, which in turn drives the right-angle extension plate 502 to move upward. The right-angle extension plate 502 drives the top block 516 to move upward, which in turn drives the sealing plate 508 to move upward. The sealing plate 508 drives the guide block 509 to move upward to clear the vertical through hole 3. The square plate 501 drives the right-angle extension plate 504 to move downward, which in turn drives the top block 519 to move downward. The top block 519 drives the sealing plate 519 to move downward. 2. Move downwards. The sealing plate 4 512 moves the guide block 4 513 downwards to clear the vertical through hole 3. The square plate 501 moves the right angle extension plate 2 503 to the left. The right angle extension plate 2 503 moves the top block 3 518 to the left. The top block 3 518 moves the sealing plate 3 510 to the left. The sealing plate 3 510 moves the guide block 3 511 to the left to clear the horizontal through hole 2. The square plate 501 moves the right angle extension plate 4 505 to the right. The right angle extension plate 4 505 moves the top block 1 514 to the right. The top block 1 514 moves the sealing plate 1 506 to the right. The sealing plate 1 506 moves the guide block 1 507 to the right to clear the horizontal through hole 2.

[0043] As top blocks 514, 516, 518, and 519 move, they also move the scraper rod and the telescopic jet rod on the insertion rod 522. The scraper rod is used to remove gas particles from the gas sensor 4, while the telescopic jet rod is used to blow away the particles that have been removed.

[0044] The surface of the drainage block is coated with an oleophobic and hydrophobic coating to prevent gas particles from adhering and avoid affecting the drainage effect due to particle accumulation.

[0045] The cover 1 has a one-way structure for preventing water mist from entering through the horizontal through hole 2 and the vertical through hole 3. The telescopic rod of the well-shaped four-end telescopic device 524 is a multi-level nested structure. Each level of telescopic rod is equipped with a precise positioning slot. Adjacent telescopic rods are nested and connected by the slot and the block.

[0046] The inside of the cover 1 is equipped with a temperature adaptive adjustment layer to reduce the impact of temperature fluctuations on detection accuracy.

[0047] The gas sensor 4 is wrapped with multiple layers of electromagnetic shielding material, and the internal electrical components such as the motor 521 are also electromagnetically shielded to block external electromagnetic interference.

[0048] In this embodiment, the cover 1 serves as the outer shell of the entire device, protecting the internal components. Its horizontal through-hole 2 and vertical through-hole 3 are channels for the entry of combustible gas. The waterproof fog-proof one-way structure at the through-holes allows combustible gas to enter while effectively preventing water fog intrusion, avoiding damage to the internal circuits and sensors due to water fog, and ensuring the normal operation of the device in a humid environment. The temperature adaptive adjustment layer inside the cover 1 can reduce the impact of temperature fluctuations on detection accuracy, creating a relatively stable working environment for the gas sensor 4.

[0049] The horizontal through-hole 2 and the vertical through-hole 3 are the key channels for combustible gas to enter the interior of the enclosure 1, providing the necessary conditions for the gas sensor 4 to sense the concentration of combustible gas. Their unobstructedness directly affects the device's detection sensitivity to combustible gas.

[0050] There are four gas sensors 4 installed at the four corners of the inner wall of the enclosure 1 to detect the concentration of combustible gas inside the enclosure 1. The multi-layer electromagnetic shielding material wrapped on the outside can effectively block external electromagnetic interference, ensuring the accuracy and stability of the sensor detection data and avoiding misjudgment due to electromagnetic interference.

[0051] The square plate 501 is connected to the driven shaft 517 and rotates under the drive of the driven shaft 517, providing a power source for the movement of the right-angle extension plate. By rotating itself, the position of the right-angle extension plate is changed, thereby driving the top block, sealing plate, and guide block.

[0052] Right-angle extension plate 1 502, right-angle extension plate 2 503, right-angle extension plate 3 504, and right-angle extension plate 4 505 are rotatably mounted on the fixing pins 1 515 at the four corners of the square plate 501 at one end, and connected to the fixing pin 2 523 at the bottom of the top block at the other end. When the square plate 501 rotates, the right-angle extension plates rotate around the fixing pins 1 515, causing the top block to move in different directions, so that the sealing plate and the dredging block can dredge the horizontal through hole 2 and the vertical through hole 3.

[0053] Sealing plate 1 (506), sealing plate 2 (508), sealing plate 3 (510), and sealing plate 4 (512) are respectively fixed to one end of top block 1 (514), top block 2 (516), top block 3 (518), and top block 4 (519) to support the dredging block and, driven by the top block, send the dredging block to the horizontal through hole 2 or the vertical through hole 3 for dredging operation.

[0054] The dredging blocks 1 (507), 2 (509), 3 (511), and 4 (513) are arranged in an array at equal intervals on the sealing plate. Their number corresponds to the number of horizontal through holes 2 or vertical through holes 3, and the block length is greater than the depth of the through holes. By inserting into the through holes, the dust, particles and other foreign objects blocking the through holes are removed to ensure the unobstructed flow of the through holes, so that combustible gases can enter the cover 1 smoothly. The oleophobic and hydrophobic coating on the surface prevents gas particles from adhering and avoids the dredging effect from being affected by the accumulation of particles.

[0055] Top blocks 1 (514), 2 (516), 3 (518), and 4 (519) are connected to the right-angle extension plate by fixing pin 2 (523) at their bottom. They move under the drive of the right-angle extension plate, thereby driving the sealing plate and the guide block to clear the through hole. At the same time, the U-shaped seat at its bottom cooperates with the insertion rod 522, driving the insertion rod 522 to move during the movement, providing power for the sensor cleaning mechanism 6.

[0056] Fixed pin 515 is fixed on the four corners of square plate 501 and is used to connect one end of right angle extension plate, so that right angle extension plate can rotate around it, realizing the conversion of the rotation of square plate 501 into linear motion of right angle extension plate and top block;

[0057] One end of the driven shaft 517 is fixedly connected to the output end of the motor 521, and the other end is fixedly inserted with a square plate 501, which transmits the rotation of the motor 521 to the square plate 501, thereby driving the entire four-sided unblocking mechanism 5 to work.

[0058] The U-shaped seat is fixed to the bottom of the top block and is set at the same horizontal line as the fixing pin 523. The insertion rod 522 passes through it. When the top block moves, the U-shaped seat drives the insertion rod 522 to move synchronously, providing guidance and power transmission for the movement of the sensor cleaning mechanism 6.

[0059] The motor 521 is installed at the center of the inner wall of the cover 1 and serves as the power source for the four-sided unblocking mechanism 5. It drives the driven shaft 517 to rotate through the output shaft, thereby driving the entire four-sided unblocking mechanism 5 to run and achieve regular unblocking of the perforation.

[0060] The insertion rod 522 is fixedly inserted into the collar at the output end of the well-shaped four-end telescopic device 524 and passes through the U-shaped seat. When the top block moves, the insertion rod 522 moves synchronously under the drive of the U-shaped seat, which drives the sensor cleaning mechanism 6 installed on it to clean the gas sensor 4.

[0061] Fixed pin 2523 is fixed to the bottom of the top block and is used to connect the other end of the right-angle extension plate to ensure that the right-angle extension plate can effectively drive the top block to move.

[0062] The well-shaped four-end telescopic device 524 consists of two sets of vertically intersecting telescopic rods with outputs at both ends. It is installed between the square plate 501 and the motor 521. The telescopic rods have a multi-level nested structure. Each level of telescopic rod is equipped with a precise positioning slot. The nested connection of adjacent telescopic rods is achieved by the cooperation of the slot and the block. The collar at the output end is fixed to the insertion rod 522. On the one hand, it supports and guides the insertion rod 522. On the other hand, the movement range and position of the four-sided unblocking mechanism 5 and the sensor cleaning mechanism 6 can be finely adjusted by adjusting the telescopic length of the telescopic rod to adapt to different working needs.

[0063] Scraper rod 1 601, scraper rod 2 603, scraper rod 3 605, and scraper rod 4 607 are mounted on the insert rod 522. When the insert rod 522 moves, it approaches the surface of the gas sensor 4 to remove gas particles attached to the gas sensor 4, keep the sensor surface clean, and ensure the sensor's sensitivity to combustible gases.

[0064] The retractable air jet rods 602, 604, 606, and 608 work in groups with the scraper rod and are also mounted on the insert rod 522. After the scraper rod removes the particles, the retractable air jet rods spray gas to blow the removed particles away from the sensor surface, preventing the particles from re-adhering and further improving the cleaning effect of the sensor to ensure its normal operation.

[0065] More specifically, the gas sensor 4, which uses quantum sensing technology, is first precisely installed in the four corners of the inner wall of the enclosure 1 to ensure that the installation is firm and that the connection lines follow strict electromagnetic shielding wiring specifications to avoid signal interference.

[0066] Next, install the intelligent four-sided unblocking mechanism 5, and install multiple micro intelligent drive modules at the connection between the right-angle extension plate and the top block to ensure that the sensor installation position of each module is accurate and can effectively sense the unblocking status. When installing the well-shaped four-end telescopic device 524, carefully adjust the initial position of the shape memory alloy telescopic rod to make it coordinated with the movement of the entire mechanism.

[0067] Then, the adaptive sensor cleaning mechanism 6 is installed. The scraper bar with micro-pressure sensor and gas composition sensor and the telescopic jet bar are diagonally grouped and fitted onto the insert rod 522 to ensure accurate installation and to enable comprehensive and effective cleaning of gas sensor 4 when insert rod 522 moves.

[0068] Finally, install the nano-temperature-controlled fluid system, intelligent waterproof fog valve, and electromagnetic shielding adaptive adjustment system to ensure that the sensors, controllers, and other components of each system are securely installed, the wiring is correctly connected, and the systems can achieve seamless communication and collaborative operation.

[0069] After the device is started, the micro intelligent drive module in the distributed intelligent drive system drives the right-angle extension plate and the top block to move in coordination according to the preset program and sensor feedback. When the guide block approaches the perforation, the drive module automatically adjusts the output torque and speed according to the perforation position and blockage detected by the sensor, so that the guide block can be accurately inserted into and clear the perforation. During this process, the shape memory alloy telescopic rod of the well-shaped four-end telescopic device 524 automatically adjusts its length according to the temperature and current changes, and dynamically optimizes the movement of the four-sided clearing mechanism 5.

[0070] At the same time, the adaptive sensor cleaning mechanism 6 starts working. The micro pressure sensor on the scraper bar monitors the contact pressure with the surface of the gas sensor 4 in real time and automatically adjusts the scraping force to ensure the cleaning effect while protecting the sensor. After the gas composition sensor detects the composition of the particles attached to the sensor surface, the telescopic jet bar adjusts the jet pressure, temperature and gas composition according to the instructions to perform deep cleaning of the sensor.

[0071] Gas sensor 4 continuously detects the concentration of combustible gas inside the enclosure 1 and transmits the signal to the subsequent processing circuit through an advanced signal processing system. Throughout the process, the nano temperature control fluid system automatically adjusts the temperature inside the enclosure 1 according to changes in ambient temperature. The intelligent waterproof fog valve adjusts its opening and closing degree based on feedback from humidity and air pressure sensors. The electromagnetic shielding adaptive adjustment system monitors and responds to external electromagnetic interference in real time, ensuring the stable and accurate operation of the device in all aspects.
