Description

Technical Field

[0001] This invention relates to the field of gas analysis device technology, and more specifically, to a portable Fourier transform infrared gas analysis device. Background Technology

[0002] Fourier transform infrared gas analyzer is an instrument that measures gas concentration based on infrared absorption spectroscopy. It utilizes the selective absorption characteristics of different gases to infrared radiation to determine the gas concentration by measuring the absorption intensity of infrared radiation by the gas.

[0003] Chinese utility model patent application number CN202322925319.2 discloses a portable Fourier transform infrared gas analyzer, including a housing. A support plate is slidably mounted on the inner wall of the housing, and an analyzer is mounted on the upper surface of the support plate. A bidirectional motor is fixedly mounted at the center of the bottom wall of the housing. This utility model uses the bidirectional motor to drive a rotating rod, which in turn drives a driven bevel gear to rotate. The driven bevel gear then drives a threaded rod to rotate, causing the support plate to move upwards. A push rod pushes the housing cover open, allowing the support plate to move the analyzer out of the housing. When the bidirectional motor rotates in the opposite direction, the threaded rod drives the support plate downwards, causing the support plate to retract the analyzer back into the housing. The push rod then pulls the housing cover closed. The bidirectional motor allows for easy and safe removal and retraction of the analyzer, and the housing design effectively prevents damage during storage and transportation.

[0013] According to an embodiment of the portable Fourier transform infrared gas analyzer of the present invention, the intake pump is configured inside the analyzer via two fastening modules. The two fastening modules are respectively configured at both ends of the intake pump. The fastening module includes a semi-circular fastening seat and a semi-circular fastening clamp. One end of the semi-circular fastening clamp is configured on the upper side of one side of the semi-circular fastening seat via a shaft seat. The other end of the semi-circular fastening clamp is fastened and connected to the upper side of the other side of the semi-circular fastening seat.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. This invention provides a portable Fourier transform infrared gas analyzer. The portable Fourier transform infrared gas analyzer has a portable mobile frame installed on the outside of a carrying case, allowing the analyzer to be pulled from inside the carrying case via the mobile frame. In use, the movable rod is pulled out from inside the mounting cylinder. A connecting piece provides a mounting position for the pull handle.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] like Figures 1-4As shown, the present invention provides a portable Fourier transform infrared gas analyzer, comprising: an analyzer body 100, the analyzer body 100 including a portable case 1 and a portable mobile frame 2, the portable case 1 containing an analyzer 200, the portable case being mounted on the portable mobile frame 2, the bottom of the portable case having multiple shock-absorbing wheels 11, the portable mobile frame 2 including a fixed cylinder 21, a movable rod 22, a movable rod 23, a connecting member 24, and a pull handle 25, the fixed cylinder 21 being symmetrically arranged at the bottom of the portable case 1, the movable rod 22 being disposed inside one end of the fixed cylinder 21, the movable rod 23 being disposed at one end of the movable rod 22, the connecting member 24 being disposed on one side of the movable rod 23, and the pull handle 25 being disposed inside the connecting member 24. Further, pads 211 are symmetrically arranged at the bottom of the fixed cylinder 21.

[0034] The portable case 1 provides a mounting location for the analyzer 200, protects it, and facilitates carrying it. Due to the analyzer's large size and weight, carrying it is physically demanding. To address this, a portable frame 2 is mounted on the outside of the portable case 1, allowing the analyzer 200 to be pulled from inside the case. In use, the movable rod 22 is pulled out from inside the fixed cylinder 21. The connecting piece 24 provides a mounting position for the pull handle 25. Shock-absorbing wheels 11 are symmetrically mounted on one side of the portable case 1. When the analytical device is pulled for use, one side of the portable case 1 is the bottom, which is supported by shock-absorbing wheels 11. The shock-absorbing wheels 11 allow the staff to pull the analytical device by pulling the handle 25. The shock-absorbing wheels 11 can reduce the vibration generated on the analyzer 200 when pulling. By pulling the analytical device, the staff can carry it more easily and conveniently, and the carrying efficiency is also improved. When the analytical device is placed for use, the movable rod 22 is moved into the fixed cylinder 21. The movable rod 23 is inserted into one end of the fixed cylinder 21 to position the movable rod 22. The pad 211 is placed at the bottom of the fixed cylinder 21 and directly contacts the placement surface to provide support.

[0035] Furthermore, the analyzer 200 is equipped with a display screen 201 and an air intake port 202 on its top. The display screen 201 allows for analysis operations and displays of analysis results. The analyzer 200 also contains an air intake pump 203, which is connected to the air intake port 202. An air intake cylinder 204 is detachably mounted on the air intake port 202. Therefore, during use, the air intake cylinder 204 can be installed on the air intake port 202. After the air intake pump 203 is started, the external gas to be analyzed is quickly drawn into the analyzer 200, facilitating analysis by the analyzer 200.

[0036] Furthermore, in some embodiments of the present invention, a fixing magnet 12 is installed on the top front of the portable case 1, a portable handle 13 is installed on the front of the portable case 1, and the portable handle 13 is located below the fixing magnet 12. A switch cover 14 is flipped up on the top of the portable case 1, a positioning magnet 15 is installed on the top of the switch cover 14, and the positioning magnet 15 is magnetically attracted to the fixing magnet 12. A heat dissipation groove 16 is formed through the bottom of the portable case 1, and a heat dissipation mesh 17 is installed inside the heat dissipation groove 16. Heat conduction grooves 18 are formed on the inner walls of both sides of the portable case 1. A mounting frame 19 is installed on the inner wall of the bottom of the portable case 1, and heat dissipation fins 191 are installed on the inner side of the mounting frame 19, and the bottom of the heat dissipation fins 191 is connected to the heat dissipation mesh 17.

[0037] The switch cover 14 is used to open or close the top of the portable case 1. When the switch cover 14 is closed, the positioning magnet 15 and the fixing magnet 12 are magnetically attracted, thereby fixing the switch cover 14. By opening the switch cover 14, the operator can use the internal analyzer 200. The air intake vent 202 allows the gas to be detected to enter the analyzer 200. The analyzed values ​​are displayed on the display screen 201. The analyzer 200 generates heat during use. In order to dissipate the heat generated by the analyzer 200 inside the portable case 1 in a timely manner, a heat sink is installed. The components allow heat to be dissipated in a timely manner. The heat conduction grooves 18 in the heat dissipation components provide heat dissipation space between the analyzer 200 and the inner wall of the portable case 1, allowing the generated heat to be dissipated to the outside through the heat dissipation grooves 16 and heat dissipation mesh 17 at the bottom. At the same time, heat dissipation fins 191 are installed through the mounting frame 19 and are directly connected to the bottom of the analyzer 200, so that the heat generated by the analyzer 200 can be conducted to the outside through the heat dissipation fins 191, avoiding the heat inside the portable case 1 from not being effectively dissipated, which would cause the internal heat to rise and affect the use.

[0038] Therefore, when carrying the main body of the analyzer, it can be pulled on the ground by the portable mobile frame 2, eliminating the need for staff to lift it using the portable handle 13. Pulling it on the ground makes it more convenient to carry. When using the analyzer, the portable mobile frame 2 is folded up, and the bottom of the portable case 1 is supported by the pad 211 and the mounting cylinder 10. The switch cover 14 is opened, and the exhaust gas is analyzed and tested by the analyzer 200. The heat generated by the analyzer 200 during use is dissipated through the heat dissipation groove 16 and heat dissipation fins 191 at the bottom, avoiding heat concentration inside and ineffective heat dissipation, which could cause damage to the internal parts of the analyzer 200 due to overheating and affect its use.

[0039] like Figure 5As shown, further, in some embodiments of the present invention, the above-mentioned suction pump 203 is installed in the analyzer 200 by two fastening modules 3. Here, the two fastening modules 3 are respectively installed at both ends of the suction pump 203 to fix the suction pump 203. And here, the fastening module 3 can be opened to facilitate the maintenance of the suction pump 203 after disassembling the analyzer 200.

[0040] like Figures 6-10 As shown, specifically, the above-mentioned fastening module 3 includes a semi-circular fastening seat 31 and a semi-circular fastening clamp 32. One end of the semi-circular fastening clamp 32 is movably mounted on the upper side of one side of the semi-circular fastening seat 31 via a shaft seat 310. Therefore, when in use, the end of the suction pump 203 is placed inside the semi-circular fastening seat 31, and then the other end of the semi-circular fastening clamp 32 is rotated to the upper side of the other side of the semi-circular fastening seat 31, thereby fastening and connecting them, so that the end of the suction pump 203 passes between the semi-circular fastening seat 31 and the semi-circular fastening clamp 32.

[0041] Furthermore, in some embodiments of the present invention, an inner opening groove 311, an outer opening groove 312, and a side bottom groove group 313 are provided on the other side of the semi-circular fastening seat 31. A movable fastener part 33 is installed in the inner opening groove 311 and the outer opening groove 312, and an inner release part 34 is installed in the side bottom groove group 313. Therefore, when the other end of the semi-circular fastening hoop 32 rotates to the upper end of the other side of the semi-circular fastening seat 31, the upper hook body 321 at the other end of the semi-circular fastening hoop 32 can be fastened and connected by the movable fastener part 33. The inner release part 34 is abutted and connected to the movable fastener part 33, which facilitates the movement of the movable fastener part 33 by the inner release part 34, so that the movable fastener part 33 releases the upper hook body 321, making it convenient to open the semi-circular fastening hoop 32.

[0042] Furthermore, in some embodiments of the present invention, a first foot plate 314 is installed at one bottom end of the semi-circular fastening seat 31, and an inner strip hole 315 is opened in the bottom of the semi-circular fastening seat 31. A second foot plate 316 is also installed in the inner strip hole 315. The second foot plate 316 can move along the inner strip hole 315. Here, the first foot plate 314 and the second foot plate 316 can be fixed by a screw.

[0043] like Figures 7-9As shown, further, in some embodiments of the present invention, the movable fastener 33 includes a first U-shaped frame 331, a second U-shaped frame 332, a third U-shaped frame 333, an inner rotating shaft 334, a swing block 335, and an L-shaped hook rod 336. The first U-shaped frame 331 and the second U-shaped frame 332 are sequentially installed in the inner opening slot 311, with the first U-shaped frame 331 inverted and positioned above the second U-shaped frame 332. The first vertical arm 3311 of the first U-shaped frame 331 and the second vertical arm 336 of the second U-shaped frame 332 are connected. 321 is movably connected. The third U-shaped frame 333 is invertedly installed in the outer opening slot 312, and the third vertical arm 3331 of the third U-shaped frame 333 is connected to the second U-shaped frame 332. The swing block 335 is installed on the third U-shaped frame 333, and the inner rotating shaft 334 is rotatably installed in the outer opening slot 312 and fixedly connected to the inner upper corner of the swing block 335. The L-shaped hook rod 336 is installed at the bottom of the swing block 335. A blocking protrusion 317 corresponding to the L-shaped hook rod 336 is also installed in the outer opening slot 312.

[0044] When the first U-shaped frame 331 engages with the semi-circular fastening hoop 32, the swing block 335 rotates outside the outer opening slot 312 via the inner rotating shaft 334. At this time, the swing block 335 needs to be moved into the outer opening slot 312, which in turn drives the third U-shaped frame 333 to move downward, and also drives the second U-shaped frame 332 and the first U-shaped frame 331 to move downward. The L-shaped hook rod 336 at the bottom of the swing block 335 is engaged with the inner side of the two blocking protrusions 317, so that the upper hook body 321 at the other end of the semi-circular fastening hoop 32 is engaged and connected downward by the first horizontal arm 3312 of the first U-shaped frame 331.

[0045] Furthermore, in some embodiments of the present invention, the upper end of the second vertical arm 3321 has an inner swing groove 3320, and an inner swing frame 35 is provided in the inner swing groove 3320. Here, the inner swing frame 35 includes an inner swing rod 351 and an inner V-shaped torsion spring 352. The inner V-shaped torsion spring 352 is installed upside down in the inner swing groove 3320, while the inner swing rod 351 is installed on one side of the inner V-shaped torsion spring 352. The upper end of the inner swing rod 351 is connected to the bottom of the first vertical arm 3311, here connected by the inner V-shaped torsion spring 351. 52 supports the inner swing rod 351, so that the first U-shaped frame 331 can tilt outward when it is above the inner opening slot 311, so that the upper hook 321 at the other end of the semi-circular fastening hoop 32 can enter under the first horizontal arm 3312 of the first U-shaped frame 331. Then the swing block 335 is rotated into the outer opening slot 312, and then the first U-shaped frame 331 rotates from tilting to moving vertically downward to the inner opening slot 311 to complete the fastening connection of the semi-circular fastening hoop 32.

[0046] Furthermore, in some embodiments of the present invention, the aforementioned inner release part 34 includes a wedge-shaped inner seat 341, a V-shaped frame 342, and a side telescopic release rod 343. Here, the V-shaped frame 342 is installed upside down in the inner bottom groove 3131 of the side bottom groove assembly 313, while the wedge-shaped inner seat 341 is installed on the top of the V-shaped frame 342 and extends into the outer opening groove 312 and abuts against the movable fastener part 33. The inner guide plate 344 of the wedge-shaped inner seat 341 is slidably installed in the first inner guide groove 3121 of the outer opening groove 312. The side telescopic release rod 343 is installed in the outer bottom groove 3132 of the side bottom groove assembly 313, and the inner end of the side telescopic release rod 343 passes through the outer bottom groove 3132 and extends to connect with the side slide rod 3421 of the V-shaped frame 342.

[0047] Therefore, when the side telescopic release lever 343 is pressed, the side telescopic release lever 343 moves along the outer bottom groove 3132, and then the side telescopic release lever 343 pushes the side sliding rod 3421 of the V-shaped frame 342, causing the side sliding rod 3421 to move inward along the inner bottom groove 3131. Then the V-shaped frame 342 retracts and moves upward, abutting against the wedge-shaped inner seat 341. Then the wedge-shaped inner seat 341 moves upward through the inner guide plate 344. The wedge-shaped inner seat 341 then actuates the L-shaped hook rod 336, causing the L-shaped hook rod 336 to move outward from the inside of the two blocking protrusions 317. In this way, the L-shaped hook rod 336 drives the swing block 335 to move out of the outer opening groove 312, thereby causing the third U-shaped frame 333, the second U-shaped frame 332, and the first U-shaped frame 331 to move upward. Then the first U-shaped frame 331 releases the upper hook body 321 of the first U-shaped frame 331. The side telescopic release rod 343 also has a release spring 3431, which makes it easy for the side telescopic release rod 343 to move out of the inner bottom groove 3131 for subsequent use.

[0048] like Figure 10 As shown, in some embodiments of the present invention, it further includes: an auxiliary inner fastener 36, which includes an inner pull strip 361, an inner pull guide block 362, and an inner pull guide plate 363. A lower semi-circular groove 318 is provided on the inner side of the semi-circular fastening seat 31, and correspondingly, an upper semi-circular groove 322 is provided on the inner side of the semi-circular fastening clamp 32. The inner pull strip 361 is installed in the lower semi-circular groove 318 and the upper semi-circular groove 322. The upper end of the inner pull strip 361 is fixed in the upper semi-circular groove 322 and close to the other end of the semi-circular fastening clamp 32. The inner pull guide block 362 is installed in the second inner guide groove 319 of the semi-circular fastening seat 31. The inner pull guide block 362 is connected to the second cross arm 3322 of the second U-shaped frame 332 through the inner pull guide plate 363, and the upper end of the inner pull guide block 362 is connected to the inner pull strip 361.

[0049] Therefore, when the swing block 335 moves the third U-shaped frame 333 downward, the third U-shaped frame 333 moves the second U-shaped frame 332 downward, and then the second cross arm 3322 moves the inner pull strip 361 into the second inner guide groove 319 through the inner pull guide plate 363 and the inner pull guide block 362, so that the inner pull strip 361 further wraps around the end of the suction pump 203, increasing the fixing effect of the fastening module 3 on the suction pump 203.
