[0002] In today's society, with increasing attention paid to environmental issues, air quality monitoring, as a key means of assessing atmospheric environmental quality, plays a vital role in understanding air pollution, formulating environmental protection policies, and protecting public health. Whether in bustling urban areas, industrial zones, or ecological protection areas, accurately grasping air quality information at different altitudes has become an urgent need in the field of environmental monitoring.

[0003] Existing air quality monitoring devices have many limitations in design and functionality, particularly in the difficulty of continuously collecting air samples at different altitudes. Although most air quality monitoring devices have altitude adjustment functions, they mostly use a single sampling port. However, the pollution levels of air at different altitudes are not the same, and this design can lead to cross-contamination of air at different altitudes, affecting the test results.

[0004] Therefore, those skilled in the art have provided an adjustable environmental monitoring device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problem that traditional environmental monitoring equipment cannot continuously collect air data at different altitudes, and that cross-contamination between different altitudes is common, this invention provides an adjustable environmental monitoring device, employing the following technical solution:

[0007] Optionally, the positioning mechanism includes a housing, one side of which is fixedly connected to a turntable, a spring is provided in the inner cavity of the housing, a positioning rod is fixedly connected to one side of the spring, a positioning groove is provided in the inner cavity of the fixed plate, and one side of the positioning rod is slidably connected to the positioning groove.

[0008] Optionally, a handle is provided on one side of the fixed rod, and the handle is fixedly connected to the rotating rod.

[0009] Optionally, the surface of the detector is provided with a bolt, the other side of which penetrates the surface of the detector and is threadedly connected to the mounting block.

[0010] Optionally, an anti-slip sleeve is provided on one side of the grip, and the inner side of the anti-slip sleeve is fixedly connected to the fixing rod.

[0011] Optionally, a damping sleeve is provided inside the fixed rod cavity, and the inner side of the damping sleeve is fixedly connected to the sampling rod.

[0012] Optionally, the inner cavity of the fixed rod is provided with a sliding groove, and a slider is fixedly connected to the surface of the sampling rod, with one side of the slider slidably connected to the sliding groove.

[0013] Optionally, a limiting groove is formed on the surface of the fixed disk, a limiting ring is fixedly connected to one side of the turntable, and one side of the limiting ring is slidably connected to the limiting groove.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The sampling mechanism of this utility model solves the problem that traditional air detection devices cannot continuously collect air samples from different heights, improving the practicality of the device. The arrangement of the turntable and the fixed plate ensures that when the operator switches to another sampling port, the other sampling ports are covered by the turntable, preventing other air detectors from performing useless detection work. There are four sampling ports, each with an independent air supply pipe and connecting pipe, which can effectively avoid cross-contamination of air at different heights and affect the final detection effect. The rotating rod allows the operator to control the sampling rod to drive the turntable to rise by pushing the rotating rod. After reaching the designated height, rotating the rotating rod can drive the turntable to adjust to different sampling ports. When used with an air pump, it can continuously collect air from different heights.

[0016] 2. The positioning mechanism of this utility model can help staff quickly locate the sampling hole, avoiding the problem of slow or no air collection caused by the sampling tube not being accurately aligned with the sampling hole. The contact surface between the positioning groove and the positioning rod is triangular, while the contact surface between the positioning rod and the positioning groove is arc-shaped. With the help of a spring, it can ensure that after the positioning rod enters the positioning groove, it can automatically disengage from the positioning groove by rotating the rotating rod. This avoids the problem that the operator needs to manually pull out the positioning rod after it enters the positioning groove before the turntable can continue to rotate, thus improving the convenience of the sampling mechanism.

[0027] In this embodiment, there are four air pumps 306, one of which is fixedly connected to the fixed plate 301. They can draw air into the sampling hole 305 and into the air delivery pipe 307 to actively collect air samples. This can reflect the quality of the surrounding air in a timely manner, is suitable for various environments, and improves detection efficiency. The inner cavity of the connecting pipe 308 is provided with a sealing gasket, and the inner side of the sealing gasket is fixedly connected to the air delivery pipe 307. This can effectively prevent the loss of air samples inside the air delivery pipe 307 or the entry of external air into the connecting pipe 308 to contaminate the sampled air and affect the final detection effect. There are four air delivery pipes 307 and four connecting pipes 308, which correspond to four air pumps 306 respectively, and can form multiple independent delivery pipelines.

[0028] Example 2:

[0029] Reference Figure 1-5 The positioning mechanism 4 includes a housing 401, one side of which is fixedly connected to the turntable 302. A spring 402 is provided inside the housing 401, and a positioning rod 403 is fixedly connected to one side of the spring 402. A positioning groove 404 is provided inside the fixed plate 301, and one side of the positioning rod 403 is slidably connected to the positioning groove 404. A handle 5 is provided on one side of the fixed rod 1, and one side of the handle 5 is fixedly connected to the turntable 304. A bolt 6 is provided on the surface of the detector 309, and the other side of the bolt 6 penetrates the surface of the detector 309 and is connected to the turntable 309. The mounting block 310 is threaded. A non-slip sleeve 7 is provided on one side of the handle 5. The inner side of the non-slip sleeve 7 is fixedly connected to the fixed rod 1. A damping sleeve 8 is provided in the inner cavity of the fixed rod 1. The inner side of the damping sleeve 8 is fixedly connected to the sampling rod 2. A sliding groove 9 is opened in the inner cavity of the fixed rod 1. A slider 10 is fixedly connected to the surface of the sampling rod 2. One side of the slider 10 is slidably connected to the sliding groove 9. A limit groove 11 is opened on the surface of the fixed plate 301. A limit ring 12 is fixedly connected to one side of the turntable 302. One side of the limit ring 12 is slidably connected to the limit groove 11.

[0030] In this embodiment: the housing 401 is cylindrical, and the surface of the positioning rod 403 is slidably connected to the housing 401, which can limit the range of motion and operation mode of the positioning rod 403. There are four positioning grooves 404, which correspond to the four sampling holes 305 respectively, so that the operator can accurately adjust the sampling tube 303 to the other sampling holes 305. The setting of bolt 6 makes the disassembly of the detector 309 more convenient, so as to facilitate the replacement or maintenance of the detector 309. The setting of handle 5 allows the operator to directly rotate the turntable 302 from the bottom of the fixed rod 1 to adjust the sampling hole 305, improving the convenience of the device. The anti-slip sleeve 7 can effectively reduce the risk of the operator dropping the device due to slipping. The damping sleeve 8 can increase the friction between the sampling rod 2 and the fixed rod 1, preventing the sampling rod 2 from automatically retracting and affecting the sampling effect. There are four sliding grooves 9 and four sliding blocks 10, which can limit the range of motion and operation mode of the sampling rod 2. The setting of limiting groove 11 and limiting ring 12 can limit the range of motion and movement mode of the turntable 302.

[0031] The implementation principle of this utility model is as follows: In use, the operator holds the fixed rod 1 with one hand and pushes the rotating rod 304 to one side with the other hand. The rotating rod 304 drives the turntable 302 to move, the turntable 302 drives the fixed plate 301 to move, and the fixed plate 301 drives the sampling rod 2 and the gas delivery tube 307 to move, thus completing the height adjustment. Then, rotating the rotating rod 304 drives the turntable 302 to rotate, the turntable 302 drives the sampling tube 303 and the housing 401 to rotate, and the housing 401 drives the spring 402 and the positioning rod 403 to rotate. When rotated, after the positioning rod 403 contacts the positioning groove 404, the spring 402 extends and drives the positioning rod 403 to embed into the positioning groove 404. At this time, the sampling tube 303 will be aligned with the sampling hole 305. The air pump 306 delivers the air in the sampling tube 303 into the detector 309 through the air supply pipe 307 and the connecting pipe 308, and the detection can be completed. By continuously pushing and rotating the rotating rod 304, the purpose of continuous sampling can be achieved, while ensuring that the air at different heights will not be cross-contaminated, thus ensuring the accuracy of the detection effect.

Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
