Description

Technical Field

[0001] This utility model relates to the technical field of sample tube replacement equipment, and in particular to a fully automatic indoor air detection sample tube replacement device. Background Technology

[0002] Indoor air quality testing involves using specialized instruments and methods to analyze the air quality in enclosed spaces, determining whether the concentration of harmful substances meets national standards, and thus assessing the impact of the indoor environment on human health. The focus is on detecting pollutants with significant health effects, such as formaldehyde, benzene, and TVOCs. Because indoor environments are relatively enclosed, pollutants tend to accumulate. Collected samples are analyzed using chemical and instrumental methods. For example, mass spectrometry can perform qualitative and quantitative analysis of compounds in air samples. During testing, a sampling tube placed in a sampling holder is inserted through a sample introduction device to extract the sample, which is then introduced into the mass spectrometer for analysis. However, currently, after analysis, the sampling tube needs to be manually removed by the testing personnel, and then an unanalyzed sampling tube needs to be manually inserted, making laboratory testing cumbersome.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Participation Figure 1-4 As shown, a fully automatic indoor air detection sample tube changing device is characterized by a workbench 1 and a placement tray 4. The lower end of the workbench 1 is equipped with support legs 2, and the upper end of the workbench 1 is equipped with a rectangular placement box 3. The placement tray 4 holds a sampling tube 401. The upper end of the workbench 1 is respectively provided with a moving structure 5 and a rotating structure 6. The moving structure 5 includes a first motor 501, a rectangular slide 502, a threaded rod 503, a rectangular slider 504, a mounting bracket 505, a first electric telescopic rod 506, a mounting base 507, a second electric telescopic rod 508, a connecting block 509, an arc-shaped clamping block 510, and an anti-slip pad 511. The upper end of the workbench 1 has a rectangular slide 502. The device is connected to an external power source, and the first motor 501 and the second motor 602 are controlled by a PLC controller.

[0022] Specifically, the support leg 2 installed at the lower end of the workbench 1 is used to support the workbench 1, the rectangular placement box 3 installed at the upper end of the workbench 1 can be used to place the analyzed sampling tube 401, and the placement tray 4 is used to place the unanalyzed sampling tube 401.

[0023] Participation Figure 2-4As shown, a No. 1 motor 501 is installed at one end of the workbench 1. A threaded rod 503 is connected to the rotating part of the No. 1 motor 501. The threaded rod 503 is installed at both ends of the rectangular slide groove 502 through bearings. A rectangular slider 504 is threaded on the outer surface of the threaded rod 503. A mounting bracket 505 is installed on the upper end of the rectangular slider 504. A No. 1 electric telescopic rod 506 is installed at the lower end of the mounting bracket 505. A mounting seat 507 is installed at the output end of the No. 1 electric telescopic rod 506. A No. 2 electric telescopic rod 508 is installed near both ends of the front end of the mounting seat 507. A connecting block 509 is installed at the output end of the No. 2 electric telescopic rod 508. An arc-shaped clamping block 510 is connected to the inner side of the connecting block 509. An anti-slip pad 511 is installed on the inner side of the arc-shaped clamping block 510.

[0024] Specifically, the threaded rod 503 connected to the rotating part of the first motor 501 is started by the PLC controller, causing the rotating part of the first motor 501 to drive the threaded rod 503 to rotate. This causes the rectangular slider 504, which is threaded on the outer surface of the threaded rod 503, to slide to one end inside the threaded rod 503. This, in turn, causes the mounting bracket 505 at the upper end of the rectangular slider 504 to move to one end. The mounting base 507 installed at the output end of the first electric telescopic rod 506 can move the mounting base 507 up and down. The second electric telescopic rod 508, which is installed near the front end of the mounting base 507 at both ends, can drive the two arc-shaped clamps 510 to clamp or release.

[0025] Participation Figure 2-4 As shown, the rotating structure 6 includes a first motor 501, a second motor 602, a rotating rod 603, a base 604, a first bearing 605, a first bevel gear 606, a rectangular groove 607, a second bevel gear 608, a second bearing 609, and a rotating shaft 610. The base 604 is installed on the upper end of the worktable 1. A protective cover 601 is installed on one end of the base 604. The second motor 602 is installed on one end of the base 604 inside the protective cover 601. The rotating part of the second motor 602 is connected to the rotating rod 603.

[0026] Specifically, the rotating rod 603 connected to the rotating part of the second motor 602 can enable the PLC controller to start the second motor 602 inside the protective cover 601, so that the rotating part of the second motor 602 drives the rotating rod 603 to rotate.

[0027] Participation Figure 2-4As shown, a rectangular groove 607 is provided inside the base 604. A first bearing 605 is installed at one end of the rectangular groove 607. A rotating rod 603 is installed on the first bearing 605. A first bevel gear 606 is installed at the other end of the rotating rod 603. A second bearing 609 is installed at the upper end of the rectangular groove 607. A rotating shaft 610 is installed on the second bearing 609. A second bevel gear 608 is installed at the lower end of the rotating shaft 610. A placement plate 4 is installed at the upper end of the rotating shaft 610. The second bevel gear 608 meshes with the first bevel gear 606.

[0028] Specifically, the first bevel gear 606 installed at the other end of the rotating rod 603 can drive the first bevel gear 606 to rotate when the rotating rod 603 rotates. Because the second bevel gear 608 meshes with the first bevel gear 606, it drives the rotating shaft 610 to rotate on the second bearing 609, thereby driving the rotating shaft 610 to rotate the placement disk 4.

[0029] It should be noted that this utility model is a fully automatic indoor air detection sample tube changing device. After the sampling tube 401 on the placement tray 4 has finished analysis, the PLC controller controls the start of the second motor 602 inside the protective cover 601. This causes the rotating part of the second motor 602 to drive the rotating rod 603 to rotate on the first bearing 605, and simultaneously drive the first bevel gear 606 installed on the other end of the rotating rod 603 to rotate. Because the second bevel gear 608 meshes with the first bevel gear 606, it drives the rotating shaft 610 to rotate on the second bearing 609. Thus, the rotating shaft 610 drives the placement tray 4 to rotate until the analyzed sampling tube 401 rotates to the lower end of the arc-shaped clamp 510. At this time, the placement tray 4 drives the unanalyzed sampling tube 401 to rotate to the working position. The first electric telescopic rod 506 extends upward, positioning the arc-shaped clamp 510 around the sampling tube 401. Simultaneously, the second electric telescopic rod 508 starts, causing the arc-shaped clamp 510 to hold the sampling tube 401. Then, the arc-shaped clamp 510 retracts, moving the sampling tube 401 away from the placement tray 4. At the same time, the PLC controller starts the first motor 501, causing its rotating part to rotate the threaded rod 503. This causes the rectangular slider 504, threaded on the outer surface of the threaded rod 503, to slide to one end within the threaded rod 503. This, in turn, moves the mounting bracket 505 at the top of the rectangular slider 504 to one end, above the rectangular placement box 3. The sampling tube 401 is then placed into the rectangular placement box 3. This process is repeated, eliminating the need for manual handling by testing personnel and improving testing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
