Description

Technical Field

[0001] This utility model belongs to the technical field of integrated portable devices for rapid detection of non-methane total hydrocarbons, and particularly relates to an integrated portable device for rapid detection of non-methane total hydrocarbons. Background Technology

[0002] Integrated portable devices for rapid detection of non-methane total hydrocarbons (NMCH) are also known as portable NMCH analyzers or portable VOCs (volatile organic compounds) detectors. These devices integrate sampling, detection, and analysis functions, enabling rapid and accurate detection of NMCH concentrations in ambient air and stationary source exhaust gases. They are characterized by portability, high efficiency, and accuracy. They are widely used in environmental monitoring, pollution source surveys, and performance evaluation of enterprise VOCs pollution control facilities, providing crucial technical support for environmental protection and pollution control.

[0003] For example, Chinese patent CN212780735U discloses a portable detector for total hydrocarbons, methane, and non-methane hydrocarbons with a drop-proof structure. The detector includes a main body and a drop-proof buckle. A display screen is embedded in the upper surface of the main body, and a protective glass is installed on the surface of the display screen. A control console is installed on the lower surface of the main body, and a switch is installed inside the control console. Anti-slip components are provided on the outer side of the main body, and shock-absorbing springs are installed inside the anti-slip components. One end of the shock-absorbing spring is connected to a movable block, and an anti-slip block is installed inside the movable block. A protruding block is fixed on the surface of the anti-slip block. A detection component is installed on the top of the main body. This portable detector for total hydrocarbons, methane, and non-methane hydrocarbons with a drop-proof structure increases the friction between the anti-slip components on both sides and the main body, thereby improving the operator's grip on the device and further preventing accidental drop, thus enhancing the device's drop resistance.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in use. For example, although the portable detector is drop-proof, rainwater may enter the device through the gaps in the buttons when the user uses it in the rain, causing damage. Therefore, we propose an integrated portable device for rapid detection of non-methane total hydrocarbons. Utility Model Content

[0006] The purpose of this invention is to provide an integrated portable device for rapid detection of non-methane total hydrocarbons, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an integrated portable device for rapid detection of non-methane total hydrocarbons, including a portable detector, and further comprising:

[0008] Two first through slots are opened on both sides of the portable detector and are connected to the inner cavity of the portable detector. Multiple miniature cooling fans are fixedly connected in the first through slots.

[0009] A waterproof housing is fixedly connected to a portable testing instrument, and an observation window and a waterproof membrane are fixedly connected to the waterproof housing.

[0010] Two slots are provided on both sides of the waterproof housing, and the two slots are respectively connected to two first through slots. Two frames are inserted into the two slots respectively, and two dustproof nets are fixedly connected to the inner cavity of the two frames respectively.

[0011] Two fixing components are located within the waterproof housing and are used to fix the two frames respectively;

[0012] Two first grooves are formed on both sides of the waterproof shell and are respectively connected to two slots. Two sealing plates are slidably connected in the two first grooves, and two threaded rods are threadedly connected in the two sealing plates.

[0013] A drive assembly, located within a waterproof housing, is used to drive two threaded rods to rotate.

[0014] Based on the above structure, the waterproof casing ensures that external moisture cannot enter the portable detector through the gaps between the buttons. The viewing window allows the user to observe the information on the portable detector's display screen. The waterproof membrane allows the user to press the buttons on the portable detector. The first through-slots and miniature cooling fans ensure that multiple miniature cooling fans can dissipate heat generated inside the portable detector through the two first through-slots. The slots and frames ensure that the two frames can be inserted into the two slots respectively, allowing the user to remove the two frames from the slots. The dustproof mesh ensures that external dust can be prevented. Multiple miniature cooling fans introduce heat into the portable testing device. A fixed assembly ensures the frame is securely fixed within the slots, preventing heat buildup during normal use. A first sliding groove and sealing plate allow the sealing plate to slide within the groove. A drive assembly and threaded rods allow the user to rotate the two threaded rods, causing the sealing plates to move along the first sliding grooves. This allows the user to control the movement of the sealing plates and seal the slots during rainy weather, preventing moisture from entering.

[0015] In the above technical solution, the fixing component further includes:

[0016] The second slide is formed on the inner wall of the slot. A plug is slidably connected in the second slide, and one end of the plug penetrates the top surface of the frame and extends into the frame to engage with the frame. The plug has a pressing groove, and the other end of the plug is fixedly connected to a spring that is fixed to the inner wall of the second slide.

[0017] The third slide groove is formed on the inner wall of the second slide groove and is connected to the outside. A pressing rod is slidably connected in the third slide groove, and one end of the pressing rod extends into the pressing groove.

[0018] In this technical solution, it is ensured that the user can fix the frame in the slot and prevent it from moving.

[0019] In the above technical solution, one end of the extrusion rod is further inclined.

[0020] In this technical solution, it is ensured that when one end of the extrusion rod presses against the inner wall of the extrusion groove, the extrusion groove can drive one end of the insert block from inside the frame into the second slide groove.

[0021] In the above technical solution, one end of the extrusion rod is further inserted into the extrusion groove.

[0022] In this technical solution, it is ensured that when the user presses the squeezing rod, one end of the squeezing rod can be inserted into the squeezing groove.

[0023] In the above technical solution, the driving component further includes:

[0024] Two gear slots are formed inside the waterproof housing and are connected to two first sliding grooves. A first bevel gear and a second bevel gear are rotatably connected in the gear slots and mesh with each other. One end of the first bevel gear passes through the inner wall of the gear slot and extends into the first sliding groove to be fixed to one end of the threaded rod.

[0025] The second through groove is formed inside the waterproof housing and is connected to two gear grooves. A rotating rod is rotatably connected inside the second through groove and is fixedly connected to two second bevel gears. One end of the rotating rod passes through the inner wall of the second through groove and extends to the outside, where it is rotatably connected to the waterproof housing.

[0026] In this technical solution, it is ensured that the user can control whether the two sealing plates seal the two slots.

[0027] In the above technical solution, one end of the first bevel gear is rotatably connected to the first sliding groove.

[0028] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear can rotate within the first groove.

[0029] In the above technical solution, the rotating rod is further rotatably connected to two gear slots.

[0030] In this technical solution, it is ensured that when the user rotates the lever, the lever can rotate normally within the two gear slots.

[0031] In the above technical solution, furthermore, the portion of the sealing plate that contacts the inner wall of the first groove is provided with a sealing gasket.

[0032] In this technical solution, it is ensured that rainwater from the outside will not enter the slot through the gap between the sealing plate and the inner wall of the first groove.

[0033] Furthermore, in the above technical solution, the pitch on both threaded rods is the same.

[0034] In this technical solution, it is ensured that when the two threaded rods rotate, the two sealing plates will be acted upon by the threads of the two threaded rods respectively, and will move the same distance along the two first sliding grooves respectively.

[0035] The beneficial effects of this utility model are:

[0053] Example 1:

[0054] Please see Figure 1 - Figure 7 As shown, this embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons, including a portable detector 1, and further comprising:

[0055] Two first through slots 2 are opened on both sides of the portable detector 1 and are connected to the inner cavity of the portable detector 1. Multiple miniature cooling fans 3 are fixedly connected inside the first through slots 2.

[0056] Waterproof housing 4 is fixedly connected to portable detector 1. Observation window 5 and waterproof membrane 6 are fixedly connected to waterproof housing 4.

[0057] Two slots 7 are provided on both sides of the waterproof housing 4, and the two slots 7 are respectively connected to the two first through slots 2. Two frames 8 are inserted into the two slots 7 respectively, and two dustproof nets 9 are fixedly connected to the inner cavity of the two frames 8 respectively.

[0058] Two fixing components are located inside the waterproof housing 4 and are used to fix the two frames 8 respectively;

[0059] Two first sliding grooves 10 are formed on both sides of the waterproof housing 4 and are respectively connected to two slots 7. Two sealing plates 11 are slidably connected in the two first sliding grooves 10, and two threaded rods 12 are threadedly connected in the two sealing plates 11.

[0060] The drive assembly is located inside the waterproof housing 4 and is used to drive the two threaded rods 12 to rotate.

[0061] Example 2:

[0062] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a fixed component:

[0063] The second slide groove 13 is formed on the inner wall of the slot 7. A plug 14 is slidably connected in the second slide groove 13. One end of the plug 14 penetrates the top surface of the frame 8 and extends into the frame 8 to be inserted and engaged with the frame 8. A pressing groove 15 is formed on the plug 14. The other end of the plug 14 is fixedly connected to a spring 16 that is fixed to the inner wall of the second slide groove 13.

[0064] The third slide 17 is formed on the inner wall of the second slide 13 and is connected to the outside. An extrusion rod 18 is slidably connected in the third slide 17, and one end of the extrusion rod 18 extends into the extrusion groove 15.

[0065] When the dustproof net 9 accumulates a lot of dust during prolonged use and needs cleaning, the user presses the squeezing rod 18 by hand, causing one end of the squeezing rod 18 to press against the inner wall of the squeezing groove 15. This causes the squeezing groove 15 to pull one end of the insert block 14 from inside the frame 8 into the second slide groove 13, compressing the spring 16. At this point, the frame 8 is released from its fixation. The user then removes the frame 8 from the slot 7 by hand and cleans the dustproof net 9. After cleaning, the user reinserts the frame 8 into the slot 7. Then, the user releases the squeezing rod 18, allowing one end of the insert block 14 to be pushed back by the spring 16 and inserted into the frame 8, fixing the frame 8 in the slot 7 so that it cannot move. This ensures that the user can fix the frame 8 in the slot 7 so that it cannot move.

[0066] Example 3:

[0067] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the extrusion rod 18 is inclined.

[0068] Specifically, when one end of the extrusion rod 18 extrudes the inner wall of the extrusion groove 15, the extrusion groove 15 can drive one end of the insertion block 14 from inside the frame 8 into the second slide groove 13.

[0069] Example 4:

[0070] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the extrusion rod 18 is inserted into the extrusion groove 15.

[0071] Specifically, it is ensured that when the user presses the squeezing rod 18, one end of the squeezing rod 18 can be inserted into the squeezing groove 15.

[0072] Example 5:

[0073] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a driving component comprising:

[0074] Two gear slots 19 are formed inside the waterproof housing 4 and are connected to two first sliding grooves 10. A first bevel gear 20 and a second bevel gear 21 are rotatably connected inside the gear slots 19, and the first bevel gear 20 and the second bevel gear 21 mesh with each other. One end of the first bevel gear 20 passes through the inner wall of the gear slot 19 and extends into the first sliding groove 10 and is fixed to one end of the threaded rod 12.

[0075] The second through groove 22 is formed inside the waterproof housing 4 and is connected to the two gear grooves 19. A rotating rod 23 is rotatably connected inside the second through groove 22 and is fixedly connected to the two second bevel gears 21. One end of the rotating rod 23 passes through the inner wall of the second through groove 22 and extends to the outside and is rotatably connected to the waterproof housing 4.

[0076] In use, the user manually rotates the rotating rod 23, causing the two second bevel gears 21 to rotate within the two gear slots 19. When the two second bevel gears 21 rotate, they in turn drive the two first bevel gears 20 to rotate. When the two first bevel gears 20 rotate, they in turn drive the two threaded rods 12 to rotate, causing the two sealing plates 11 to be acted upon by the threads of the two threaded rods 12 and move along the two first sliding grooves 10. This ensures that the user can control whether the two sealing plates 11 seal the two slots 7.

[0077] Example 6:

[0078] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the first bevel gear 20 is rotatably connected to the first slide groove 10.

[0079] Specifically, it is ensured that when the first bevel gear 20 rotates, one end of the first bevel gear 20 can rotate within the first slide groove 10.

[0080] Example 7:

[0081] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: the rotating rod 23 is rotatably connected to two gear slots 19.

[0082] Specifically, it is ensured that when the user rotates the lever 23, the lever 23 can rotate normally within the two gear slots 19.

[0083] Example 8:

[0084] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: the part of the sealing plate 11 that contacts the inner wall of the first slide groove 10 is provided with a sealing gasket.

[0085] This ensures that rainwater from the outside will not enter the slot 7 through the gap between the sealing plate 11 and the inner wall of the first groove 10.

[0086] Example 9:

[0087] This embodiment provides an integrated portable device for rapid detection of non-methane total hydrocarbons. In addition to the technical solutions of the above embodiments, it also has the following technical features: the pitch on the two threaded rods 12 is the same.

[0088] Specifically, when the two threaded rods 12 rotate, the two sealing plates 11 will be acted upon by the threads of the two threaded rods 12 respectively, and will move the same distance along the two first sliding grooves 10 respectively.

[0089] In use, the user manually rotates the lever 23, causing the lever 23 to drive the two second bevel gears 21 to rotate within the two gear slots 19 respectively. When the two second bevel gears 21 rotate, they will drive the two first bevel gears 20 to rotate. When the two first bevel gears 20 rotate, they will drive the two threaded rods 12 to rotate, causing the two sealing plates 11 to be acted upon by the threads of the two threaded rods 12 and move along the two first sliding grooves 10 respectively. This ensures that the user can control whether the two sealing plates 11 seal the two slots 7. When the two slots 7 are sealed, the user can use the portable detector 1 in rainy weather. When the user uses the portable detector 1 in rainy weather, the rainwater from the outside will be blocked by the waterproof housing 4 and the two sealing plates. Plate 11 blocks the outside to prevent water from entering the inner cavity of the portable detector 1. At the same time, the user can view the data on the display screen of the portable detector 1 through the observation window 5 and press the button on the portable detector 1 through the waterproof membrane 6. When the two sealing plates 11 release the seal on the two slots 7, the user starts multiple miniature cooling fans 3, which dissipate the heat generated inside the portable detector 1 to the outside through the two first through slots 2. Meanwhile, the two dustproof nets 9 prevent dust from entering the inner cavity of the portable detector 1 through the gaps in the multiple observation windows 5, so that the heat generated by the portable detector 1 when used on sunny days can be dissipated to the outside, preventing the accumulation of a large amount of heat inside the portable detector 1 from causing damage.

[0090] When the dust filter 9 accumulates a lot of dust during prolonged use and needs cleaning, the user presses the squeezing rod 18 by hand, causing one end of the squeezing rod 18 to press against the inner wall of the squeezing groove 15. This causes the squeezing groove 15 to pull one end of the insert block 14 from inside the frame 8 into the second slide groove 13, compressing the spring 16. At this point, the frame 8 is released from its fixation. The user then removes the frame 8 from the slot 7 by hand and cleans the dust filter 9. After cleaning, the user reinserts the frame 8 into the slot 7. Then, the user releases the squeezing rod 18, allowing one end of the insert block 14 to be pushed back by the spring 16 and inserted into the frame 8, fixing the frame 8 in the slot 7 so that it cannot move. This ensures that the user can fix the frame 8 in the slot 7 so that it cannot move.

[0091] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
