Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring equipment, and in particular relates to a gas capture device for environmental monitoring and analysis. Background Art

[0002] Gas capture devices mainly collect and analyze gas samples in the air to assess the degree of environmental pollution, monitor the concentration of harmful gases, and track emission sources. They are widely used in environmental monitoring, industrial safety, occupational health and other fields.

[0003] When conducting environmental monitoring and analysis, a gas capture device is needed to sample the gas so as to analyze harmful substances in the gas. In actual use, the existing gas capture device mainly connects the sampler and the sampler connector on the top of the gas capture device to complete the capture of the gas sample. However, when the gas capture device is in an idle state, its sampler connector is generally directly exposed to the air. Due to the lack of corresponding protective measures, impurities such as floating dust in the air will enter the sampler connector, thereby causing pollution to the sampler connector.

[0017] 3. The present invention provides an extension column, a limit block, a threaded rod, a rectangular block and an inclined rod. When the second handle is turned, the threaded rod will rotate along the inner surface of the support block. Since the outer surface of the threaded rod and the inner surface of the rectangular block are threadedly sleeved, the rectangular block will move with the top of the inclined rod as the threaded rod rotates, so that the other end of the inclined rod generates a thrust on the limit block, pushing the limit block to move with the extension column along the inner surface of the limit groove. By adjusting the height of the extension columns at the four corners at the bottom end of the main body of the gas capture device, the leveling operation of the gas capture device can be achieved.

[0036] As a technical optimization solution of the present invention, when the driving motor 20 is started, the rotating rod 22 and the round rod 18 will rotate through the driving shaft 21.

[0037] refer to Figures 1 to 4 and Figure 7 The four corners at the bottom of the main body 1 of the gas capture device are fixedly installed with support legs 23, the number of which is four, and the insides of the four support legs 23 are movably connected with extension columns 24, the number of which is four and the shape and size of the extension columns are the same.

[0038] As a technical optimization solution of the present invention, due to the existence of the support legs 23 and the extension columns 24, the height of the four corners at the bottom of the gas capture device body 1 can be adjusted, thereby achieving a leveling operation of the gas capture device.

[0039] refer to Figure 2 , Figure 4 and Figure 7 The four supporting legs 23 are respectively provided with limiting grooves 25 on one side facing the center position of the main body 1 of the gas capture device. The top of the limiting groove 25 is movably sleeved with a limiting block 26. There are four limiting blocks 26. The outer surfaces of the four limiting blocks 26 are respectively fixedly connected to the outer surfaces of the four extension columns 24.

[0040] As a technical optimization solution of the present invention, the inner surface of the limiting groove 25 and the outer surface of the limiting block 26 are both smooth, ensuring that the limiting block 26 will not get stuck when moving along the inside of the limiting groove 25.

[0041] refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 The tops of the four supporting legs 23 are movably sleeved with threaded rods 27, the left ends of the threaded rods 27 penetrate the supporting legs 23 and extend to the outside of the supporting legs 23 and are fixedly sleeved with a second handle 28, the outer surface of the second handle 28 is movably connected to the outer surface of the supporting legs 23, the right end of the threaded rods 27 penetrates the supporting legs 23 and extends to the outside of the supporting legs 23 and is movably sleeved with a supporting block 29, the top of the supporting block 29 is fixedly connected to the bottom end of the gas capture device body 1.

[0042] As a technical optimization solution of the present invention, when the second handle 28 is turned, the threaded rod 27 will rotate along the inner surfaces of the support leg 23 and the support block 29 .

[0043] refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 A rectangular block 30 is threadedly sleeved on the right side of the outer surface of the threaded rod 27. The top of the rectangular block 30 is movably connected to the bottom end of the gas capture device body 1. The outer surface of the rectangular block 30 is movably connected to the outer surface of the support block 29. An inclined rod 31 is hinged at the bottom end of the rectangular block 30. The other end of the inclined rod 31 is hinged to the right end of the limit block 26.

[0044] As a technical optimization solution of the present invention, when the threaded rod 27 rotates, the rectangular block 30 will move with the inclined rod 31, so that the other end of the inclined rod 31 will generate a thrust on the limit block 26, pushing the limit block 26 to move with the extension column 24.

[0045] Working principle and usage process:

[0046] First, after the operator places the gas capture device at the specified position, the operator connects the sampler and the sampler connector 4. If the gas capture device is not placed stably and shakes, the operator turns the second handle 28 on the tilted side to rotate the threaded rod 27. At this time, the rectangular block 30 threadedly connected to the threaded rod 27 will move along the bottom end of the gas capture device body 1 with the top of the inclined rod 31, so that the bottom end of the inclined rod 31 generates a thrust on the limit block 26, pushing the limit block 26 to move downward along the inner surface of the limit groove 25 with the extension column 24 until the gas capture device returns to stability. By adjusting the extension columns 24 at the four corners of the bottom end of the gas capture device body 1, the leveling operation of the gas capture device can be achieved, thereby improving the stability of the placement of the gas capture device.

[0047] When the display screen 14 is blurred, the operator starts the drive motor 20, causing the drive shaft 21 to rotate with the round rod 18 through the rotating rod 22, so that the outer surface of the round rod 18 generates a thrust on the inner surface of the long rod 17, pushing the long rod 17 to reciprocate along the outer surface of the limit frame 15 with the cleaning rod 16. Since the outer surface of the display screen 14 and the outer surface of the cleaning rod 16 are movably connected, the outer surface of the display screen 14 can be cleaned as the cleaning rod 16 moves, thereby preventing the display screen 14 from becoming blurred and affecting the use of the gas capture device.

[0048] When the gas capture device is used up, the operator removes the sampler and then pulls the first handle 9, so that the first handle 9 moves upward along the inner surface of the cover 7 with the circular plate 10 through the insertion rod 8 and compresses the spring 11. Then the operator rotates the cover 7, so that the cover 7 rotates with the connecting block 6 around the circular axis 5. When the circular plate 10 and the positioning block 12 are aligned, the operator releases the first handle 9. At this time, under the restoring action of the spring 11, the circular plate 10 will return to its original position and be embedded in the positioning block 12. The operator can use the cover 7 to complete the dustproof protection of the sampler connector 4, thereby preventing floating dust in the air from entering the sampler connector 4.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
