[0002] Environmental detection refers to the use of modern scientific and technological methods such as physics, chemistry, and biology to continuously or intermittently monitor and measure environmental chemical pollutants, physical and biological pollution factors, etc. at the scene. The main method for environmental detection departments to detect environmental air quality is to detect the air in different regions. When detecting and processing environmental quality, a gas detection device for environmental quality inspection is required.

[0003] Most of the current detection devices are integrated, which will lead to the inability to adjust the height position of the detection device according to actual needs when detecting and processing environmental gases. Since the gas quality at different height positions is also different, if the height position of the detection device cannot be adjusted, it will cause the detection device to only be able to effectively sample and detect the gas at a fixed height, and unable to effectively sample and detect the gas at a higher position, resulting in inaccurate gas quality detection results and reducing the overall practicality of the detection device. Moreover, most of the current detection devices do not have a structure for intercepting particulate impurities in the gas, which will cause the particulate impurities in the gas to be adsorbed into the interior of the detection device together, not only affecting the gas quality detection results, but also causing damage to the overall detection device due to long-term impurity accumulation, reducing the overall service life of the detection device.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1 - Figure 7 as shown in the figure, this embodiment provides a gas detection device for environmental quality inspection, including a base 1, and further including:

[0030] An L-shaped plate 5, located above the base 1;

[0031] An adjusting component, arranged on the upper surface of the base 1 and used to adjust the height position of the L-shaped plate 5;

[0032] A collection cylinder 6, fixedly connected to the upper surface of the base 1;

[0033] A collection and detection component, arranged on the upper surface of the L-shaped plate 5 and used to collect, detect and process the gas in the environment;

[0034] An interception component, arranged outside the collection and detection component and used to intercept and process the particulate impurities contained in the environmental gas;

[0035] The support frame 18 is fixedly connected to the upper surface of the base 1, and the upper surface of the support frame 18 is fixedly connected with a display 19.

[0036] The above working principle: When it is necessary to detect and process the gas quality in the environment, just move the whole device to the required position first. At this time, the collection and detection component starts to operate. The collection and detection component can effectively collect and detect the gas in the environment. After the gas detection is completed, the staff can view the various indicators of the gas through the display 19, so as to achieve the purpose of detecting the gas quality. When it is necessary to adjust the height position of the collection and detection component according to actual needs, just through the adjustment component, the height position of the L-shaped plate 5 can be conveniently adjusted. The L-shaped plate 5 then drives the collection and detection component to move synchronously. At this time, the gas quality at higher or lower positions can be detected and processed, so as to effectively improve the accuracy of gas quality detection and the overall practicality of the detection device. When collecting, adsorbing, detecting and processing the gas, the particulate impurities in the gas may affect the detection result of the gas quality. At this time, the interception component can effectively intercept and filter the particulate impurities in the gas, so as to prevent the particulate impurities from entering the inside of the detection device and causing damage to the detection device, etc., effectively extending the service life of the detection device, and improving the accuracy of the detection device for gas quality detection, saving time and effort.

[0037] In order to effectively adjust the height position of the L-shaped plate 5, the adjustment assembly includes an adjustment plate 2 fixedly connected to the upper surface of the base 1. A reciprocating motor 7 is fixedly connected to the outside of the adjustment plate 2. The output shaft of the reciprocating motor 7 is fixedly connected to a bidirectional threaded rod 8 through a coupling. The other end of the bidirectional threaded rod 8 is rotatably connected to the inner wall of the adjustment plate 2. Threaded blocks 9 are symmetrically arranged on the outside of the bidirectional threaded rod 8. A guiding groove for the movement of the threaded blocks 9 is provided on the upper surface of the adjustment plate 2. A fixing plate 12 is arranged above the adjustment plate 2. Both of the two threaded blocks 9 are hinged to the fixing plate 12 through connecting rods 13. The upper surface of the fixing plate 12 is fixedly connected to the bottom of the L-shaped plate 5. A support block 10 is fixedly connected to the inside of the adjustment plate 2. A first telescopic rod 11 is fixedly connected to the upper surface of the support block 10. The telescopic end of the first telescopic rod 11 is fixedly connected to the bottom of the fixing plate 12. When it is necessary to adjust the height position of the L-shaped plate 5, the reciprocating motor 7 starts to operate. At this time, the reciprocating motor 7 will drive the bidirectional threaded rod 8 to rotate synchronously. The threaded blocks 9 will move synchronously on the outside of the bidirectional threaded rod 8. Since both of the two threaded blocks 9 are hinged to the fixing plate 12 through the connecting rods 13, at this time, the threaded blocks 9 will drive the fixing plate 12 to move synchronously through the connecting rods 13. The fixing plate 12 will drive the L-shaped plate 5 to move synchronously. The L-shaped plate 5 will drive the collection and detection assembly to move synchronously. At this time, the collection and detection assembly can detect and process the gas quality at different height positions, so as to effectively improve the accuracy of the detection assembly for gas quality detection and the overall practicality of the detection device. During the movement of the fixing plate 12, the first telescopic rod 11 will also be stretched and squeezed synchronously. At this time, the first telescopic rod 11 can effectively play a role in limiting and guiding, so as to effectively improve the stability of the L-shaped plate 5 during movement.

[0038] Considering that when detecting and processing the gas quality, it is necessary to collect the gas first, the collection and detection component includes a suction pump 32 fixedly connected to the upper surface of the L-shaped plate 5. An installation groove for installing the intake pipe 15 is formed through one side of the L-shaped plate 5. The intake end of the intake pipe 15 is communicated with an intake hopper 14. The outlet end of the intake pipe 15 is connected to the intake end of the suction pump 32 through a pipeline. The outlet end of the suction pump 32 is connected to the inside of the collection cylinder 6 through a pipeline. A gas quality detector 23 is fixedly connected to the inside of the collection cylinder 6. The gas quality detector 23 is electrically connected to the display 19 through a wire. The outside of the collection cylinder 6 is fixedly connected with a closing cover 20 through bolts. One side of the closing cover 20 is communicated with an exhaust pipe 22 through a solenoid valve 21. When it is necessary to detect and process the gas quality, the suction pump 32 starts to operate. At this time, the suction pump 32 can adsorb the gas in the external environment through the intake hopper 14 into the intake pipe 15 and then transmit it into the collection cylinder 6 through the pipeline. When the gas enters the collection cylinder 6, the gas quality detector 23 starts to operate. At this time, the gas quality detector 23 can effectively detect and process the gas quality and then transmit the detected data results to the display 19. At this time, it is convenient for the staff to view the various indicators of the gas. When the gas detection is completed, the solenoid valve 21 is opened. At this time, the gas in the collection cylinder 6 will be discharged through the exhaust pipe 22. When it is necessary to repair the gas quality detector 23, just unscrew the bolts first and then pull out the closing cover 20. At this time, the closing cover 20 can be opened, which is convenient for the staff to clean the inside of the collection cylinder 6 and at the same time convenient for the staff to repair the gas quality detector 23.

[0039] In order to effectively intercept and process the particulate impurities contained in the external environmental gas, the intercepting component includes a fixed frame 16 symmetrically arranged outside the air inlet hopper 14. A filter screen 17 is arranged outside the air inlet hopper 14. Connecting plates 30 are symmetrically arranged outside the filter screen 17. Mounting blocks 25 are fixedly connected to the outside of both connecting plates 30. Guide grooves for the mounting blocks 25 to move are formed inside both fixed frames 16. An inner plate 26 is fixedly connected to the inside of the mounting block 25. Second telescopic rods 27 are fixedly connected to both sides of the outer wall of the inner plate 26. The telescopic ends of multiple second telescopic rods 27 are all fixedly connected with inserting rods 28. Return springs 29 are sleeved outside multiple second telescopic rods 27. Multiple return springs 29 all abut between the inserting rods 28 and the inner plate 26. Guide grooves for the inserting rods 28 to move are formed on both sides of the outer walls of both mounting blocks 25 and the fixed frames 16. When it is necessary to intercept and process the particulate impurities in the gas, only need to press the inserting rod 28 first. At this time, the inserting rod 28 will simultaneously squeeze the second telescopic rods 27 and the return springs 29. Then insert the mounting block 25 into the guide groove inside the fixed frame 16. At this time, the mounting block 25 will drive the inserting rod 28 to move synchronously. When the mounting block 25 drives the inserting rod 28 to move into the guide grooves on both sides of the outer wall of the fixed frame 16, the return spring 29 resets and drives the inserting rod 28 to move synchronously. When the inserting rod 28 is inserted into the guide grooves on both sides of the outer wall of the fixed frame 16, the mounting block 25 can be fixed to the fixed frame 16. At this time, the filter screen 17 can be installed. Thus, the particulate impurities contained in the gas can be intercepted through the filter screen 17, preventing the particulate impurities in the gas from entering the inside of the detection device and causing damage to the detection device, effectively extending the service life of the detection device. At the same time, it can effectively improve the accuracy of the gas quality detection result of the detection device. And this structure is simple, facilitating the staff to disassemble and assemble the filter screen 17.

[0040] In order to further improve the stability of the L-shaped plate 5 during movement, guide rods 3 are symmetrically arranged on the upper surface of the base 1. The tops of the two guide rods 3 are fixedly connected with a limiting plate 4. Guide plates 31 are symmetrically arranged outside the L-shaped plate 5. Guide grooves for the guide rods 3 to move are formed inside both guide plates 31. During the movement of the L-shaped plate 5, it will also drive the guide plates 31 to move synchronously outside the guide rods 3. At this time, both the guide plates 31 and the guide rods 3 can effectively play a role in limiting and guiding, so as to further improve the stability of the L-shaped plate 5 during movement.

[0041] In addition, in order to further improve the sealing performance after the closure of the closing cover 20 and the collection cylinder 6, a rubber sealing ring 24 is adhesively bonded to the inner wall of the closing cover 20. When the closing cover 20 and the collection cylinder 6 are closed, the rubber sealing ring 24 can effectively improve the sealing performance between the closing cover 20 and the collection cylinder 6, thereby preventing the leakage of the gas inside the collection cylinder 6 and affecting the detection effect of the gas quality.
