Description

Multi-channel mixed gas detection modular semiconductor sensor array Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a modular semiconductor sensor array for multi-channel mixed gas detection. Background Technology

[0002] Accurate detection of the composition and concentration of mixed gases is crucial in numerous fields, including industrial production, environmental monitoring, and daily life. For example, in chemical production, real-time monitoring of mixed gases generated during reactions ensures production safety and controls product quality. In indoor air quality testing, understanding the levels of various harmful gases helps maintain a healthy living environment for people.

[0003] However, existing gas detection equipment has many shortcomings in practical applications. Traditional gas detection devices are often complex in structure and have low integration between components, making it difficult to achieve rapid assembly and disassembly. This brings great inconvenience to the installation, maintenance and upgrading of the equipment. In addition, the height adjustment function of some detection devices is limited, making it difficult to adapt to different detection scenarios and usage requirements, resulting in insufficient practicality. Therefore, it is necessary to redesign a multi-channel mixed gas detection modular semiconductor sensor array to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-channel modular semiconductor sensor array for mixed gas detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular semiconductor sensor array for multi-channel mixed gas detection includes a base plate. A bidirectional screw is rotatably mounted on the upper surface of the base plate via a connecting frame. A rocker wheel is fixedly mounted on the outer wall of the bidirectional screw. Two moving blocks are threadedly mounted on the outer wall of the bidirectional screw via a limiting mechanism. A first connecting frame is fixedly mounted on the upper surface of each of the two moving blocks. A second connecting frame is rotatably connected inside each of the two first connecting frames via a connecting mechanism. A support plate is fixedly connected to the upper surface of the two second connecting frames. A battery is slidably mounted on the upper surface of the support plate via a mounting frame.

[0007] The upper end face of the mounting frame is fixedly mounted with a mounting base via a detection box. Multiple detection modules are slidably mounted on the upper end face of the mounting base via mounting slots. A prismatic rod is fixedly mounted on the bottom wall of each mounting slot via a movable slot. Two clamping plates are slidably mounted on the outer wall of each prismatic rod. Two springs are mounted on the outer wall of each prismatic rod. The two ends of each spring are elastically connected to the inner wall of the corresponding movable slot and the outer wall of the clamping plate, respectively. A mixed-flow fan pump is fixedly mounted on the upper end face of the mounting frame. A terminal device is fixedly mounted on the outer wall of the detection box via an installation opening. The terminal device is electrically connected to each detection module and the mixed-flow fan pump. A connecting pipe is fixedly mounted on the outer wall of the outlet pipe of the mixed-flow fan pump. Multiple diversion pipes communicating with the interior are fixedly mounted on the outer wall of the connecting pipe, and each diversion pipe penetrates into the corresponding mounting slot.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the connecting frame, and the limiting rod slides through the two moving blocks.

[0009] Preferably, the connecting mechanism includes a connecting plate rotatably mounted inside the first connecting frame, and the end of the connecting plate is rotatably connected to the inside of the second connecting frame.

[0010] Preferably, the outer wall of the mounting frame is threaded and rotatably mounted with a pressing bolt, the end of the pressing bolt is fixedly mounted with a connecting block, the end of the connecting block is rotatably connected with a pressing plate, and the inner wall of the pressing plate is fixedly mounted with an anti-slip pad.

[0011] Preferably, the outer wall of the inlet pipe of the mixed flow fan pump is fixedly installed in the purification frame, a filter screen plate is fixedly installed inside the purification frame, and a filter cloth is fixedly installed on the outer wall of the filter screen plate.

[0012] The outer wall of the testing box is fixedly equipped with an exhaust channel communicating with multiple mounting slots. A cover plate is slidably installed on the upper end face of the testing box. A sealing gasket that matches the upper end face of the mounting seat is fixedly installed on the bottom wall of the cover plate. Two fixing bolts are rotatably installed through the outer walls on both sides of the rear cover plate. Threaded holes that mate with the two fixing bolts are opened on the outer walls on both sides of the testing box.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up components such as prismatic rods, clamping plates, and springs, the clamping plates will tightly fit against both sides of the detection module under the action of the spring elastic force, firmly fixing it in the mounting slot. When the detection module needs to be replaced or maintained, the operator only needs to overcome the spring force and push the clamping plates to both sides to easily remove the detection module. The operation is simple and convenient, greatly shortening the equipment maintenance time and reducing maintenance costs.

[0015] 2. By incorporating components such as a bidirectional screw, a moving block, and a connecting plate, the operator only needs to turn the rocker wheel to rotate the bidirectional screw. Under the limiting action of the limit rod, the moving block will move along the bidirectional screw in opposite directions, thereby changing the height of the support plate through the connecting plate, achieving adjustment of the overall height of the testing equipment. This allows the equipment to be flexibly adapted to different testing scenarios and actual needs. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Referring to Figures 1-6, a multi-channel mixed gas detection modular semiconductor sensor array includes a base plate 1. A bidirectional screw 3 is rotatably mounted on the upper surface of the base plate 1 via a connecting frame 2. A rocker wheel 4 is fixedly mounted on the outer wall of the bidirectional screw 3. Two moving blocks 6 are threadedly mounted on the outer wall of the bidirectional screw 3 via a limiting mechanism. A first connecting frame 7 is fixedly mounted on the upper surface of each of the two moving blocks 6. A second connecting frame 9 is rotatably connected inside each of the two first connecting frames 7 via a connecting mechanism. A support plate 10 is fixedly connected to the upper surface of the two second connecting frames 9. A battery 12 is slidably mounted on the upper surface of the support plate 10 via a mounting frame 11.

[0025] A mounting base 17 is fixedly mounted on the upper end of the mounting frame 11 via the detection box 16. Multiple detection modules 18 are slidably mounted on the upper end of the mounting base 17 via the mounting groove. A prismatic rod 19 is fixedly mounted on the bottom wall of each mounting groove via a moving groove. Two clamping plates 20 are slidably mounted on the outer wall of each prismatic rod 19. Two springs 21 are installed on the outer wall of each prismatic rod 19. The two ends of each spring 21 are elastically connected to the inner wall of the corresponding moving groove and the outer wall of the clamping plate 20, respectively. A mixed-flow fan pump 22 is fixedly mounted on the upper end of the mounting frame 11. A terminal device is fixedly mounted on the outer wall of the detection box 16 via the installation opening. The terminal device is electrically connected to each detection module 18 and the mixed-flow fan pump 22. A connecting pipe 23 is fixedly mounted on the outer wall of the outlet pipe of the mixed-flow fan pump 22. Multiple diversion pipes 24 communicating with the interior are fixedly mounted on the outer wall of the connecting pipe 23. Each diversion pipe 24 passes through the interior of the corresponding mounting groove.

[0026] The limiting mechanism includes a limiting rod 5 fixedly installed inside the connecting frame 2, and the limiting rod 5 slides through the two moving blocks 6.

[0027] Furthermore, the setting of the limit rod 5 effectively restricts the movement direction of the moving block 6, so that it can only move along the axial direction of the bidirectional screw 3, avoiding the moving block 6 from shifting or rotating during movement, and ensuring the smooth operation of the entire height adjustment structure.

[0028] The connecting mechanism includes a connecting plate 8 rotatably installed inside the first connecting frame 7, and the end of the connecting plate 8 is rotatably connected to the inside of the second connecting frame 9.

[0029] Furthermore, the end of the connecting plate 8 is rotatably connected to the inside of the second connecting frame 9. This double rotatable connection structure allows for flexible adjustment of the height and angle of the support plate 10 when the moving block 6 moves, ensuring that the support plate 10 remains horizontal during height adjustment and providing a stable installation foundation for subsequent components.

[0030] A compression bolt 13 is threadedly installed through the outer wall of the mounting frame 11. A connecting block 14 is fixedly installed at the end of the compression bolt 13. A compression plate 15 is rotatably connected to the end of the connecting block 14. An anti-slip pad is fixedly installed on the inner wall of the compression plate 15.

[0031] Furthermore, a connecting block 14 is fixedly installed at the end of the extrusion bolt 13. The connecting block 14 is used to connect the extrusion bolt 13 and the extrusion plate 15. Its structural design can effectively transmit the extrusion force. The extrusion plate 15 can be finely adjusted under the action of the connecting block 14 to ensure the fit with the surface of the battery 12. The anti-slip pad is made of rubber and has raised texture on its surface to increase the friction between it and the battery 12, ensuring that the battery 12 is firmly clamped and preventing it from shaking or shifting during equipment operation.

[0032] The inlet pipe of the mixed flow fan pump 22 is fixedly installed on the outer wall of the purification frame 26. The filter screen plate 27 is fixedly installed inside the purification frame 26, and the filter cloth is fixedly installed on the outer wall of the filter screen plate 27.

[0033] The outer wall of the test box 16 is fixedly installed with an exhaust channel 25 that communicates with multiple mounting slots. A cover plate 28 is slidably installed on the upper end face of the test box 16. A sealing gasket that matches the upper end face of the mounting seat 17 is fixedly installed on the bottom wall of the cover plate 28. Two fixing bolts are rotatably installed through the outer walls on both sides of the rear cover plate 28. Threaded holes that mate with the two fixing bolts are opened on the outer walls on both sides of the test box 16.

[0034] When this utility model is in use, the storage battery 12 can conveniently power the mixed-flow fan pump 22 and the terminal equipment. The terminal equipment can transmit electrical signals and supply power to each detection module 18 through the data cable. Before gas detection, multiple different detection modules 18 can be placed between two opposing clamping plates 20. Under the elastic action of the spring 21, the clamping plates 20 will tightly clamp the detection modules 18, ensuring that the detection modules 18 are stably installed in the mounting slot, avoiding the impact of shaking or displacement on the accuracy of the detection results. Different detection modules 18 can perform specific detection for different types of gases, thus realizing the function of simultaneous detection of multiple mixed gases. Subsequently, the mixed-flow fan pump 22 is started, and the mixed gas from the outside is sucked into the purification frame 26. When the gas passes through the filter screen 27 and the filter cloth on its outer wall, the dust, impurities, etc. are effectively intercepted and filtered, thereby ensuring that the gas entering the subsequent detection stage is relatively pure, reducing the interference of impurities on the detection module 18, extending the service life of the detection module 18 and improving the detection accuracy.

[0035] The purified gas enters the connecting pipe 23 and is then evenly distributed to the mounting slots of each detection module 18 through the splitter pipe 24. Each detection module 18 begins to detect the gas it comes into contact with and converts the detected gas information into electrical signals. These electrical signals are transmitted to the terminal device that is electrically connected to the detection module 18. After receiving the electrical signals from each detection module 18, the terminal device analyzes and processes them, converting the electrical signals into intuitive gas composition and concentration data, which is then displayed and recorded. Operators can quickly understand the specific situation of the detected mixed gas by viewing the data on the terminal device.

[0036] If the height of the testing equipment needs to be adjusted, the operator can turn the rocker wheel 4, which drives the bidirectional screw 3 to rotate. Due to the limiting effect of the limit rod 5 on the moving block 6, the two moving blocks 6 will move towards or away from each other along the bidirectional screw 3. The movement of the moving block 6 will change the height of the support plate 10 through the connecting plate 8, thereby realizing the flexible adjustment of the height of the entire testing equipment to adapt to different testing scenarios and usage requirements. After the testing work is completed, the gas after testing is discharged from the testing box 16 through the exhaust channel 25. If the testing module 18 needs to be replaced or maintained, the operator can open the cover plate 28 and release the spring 21 from the clamping plate 20 to easily take out the testing module 18 for corresponding operations. As for the battery 12, if its power is insufficient, the squeezing bolt 13 can be turned to release the squeezing plate 15 from squeezing the battery 12, and then the battery 12 can be taken out for charging or replaced with a new battery 12 to ensure that the equipment can operate continuously and stably.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
