It is the science and technology that studies and engages in the prevention and control of environmental pollution and the improvement of environmental quality. Air quality has become a very important indicator in China's environmental monitoring. Therefore, it is necessary to detect and monitor the air quality of various environments, take timely measures to purify the air, ensure air quality, and reduce the harm of polluted air to people's health.

[0029] This utility model provides the following technical solution:
[0030] Example 1
[0031] Please see Figure 1-5This utility model provides a technical solution: a dynamic air monitoring device for environmental protection engineering monitoring, including a base 1 and an air monitor 3. The bottom of the base 1 is symmetrically and fixedly connected with casters 2. The top of the base 1 is provided with a height adjustment mechanism 4. The top of the height adjustment mechanism 4 is provided with a lifting seat 5. The top of the lifting seat 5 is symmetrically and fixedly connected with fixing rods 6. The top of the four fixing rods 6 is fixedly connected with a placement seat 7. The bottom of the placement seat 7 is provided with a fixing mechanism 8. The fixing mechanism 8 is used to install the air monitor 3 on the placement seat 7.
[0032] The fixing mechanism 8 includes a fixing plate 81, which is symmetrically fixed to the bottom of the placement seat 7. A bidirectional lead screw 82 is rotatably connected between the two fixing plates 81. A limit rod 83 is symmetrically fixed between the two fixing plates 81. A second servo motor 84 is fixedly connected to the right side of the fixing plate 81 near the bottom of the placement seat 7. A movable plate 85 is symmetrically threaded on the surface of the bidirectional lead screw 82. A movable frame 86 is symmetrically fixed to the side of the movable plate 85 near the fixing plate 81. A rubber clamp 87 is fixedly connected to the other end of the movable frame 86. The movable frame 86 is partially movable through the fixing plate 81 and fixed to the rubber clamp (87). The air monitor 3 is clamped between the rubber clamps 87.
[0033] The base 1 has a hole on the right side of the fixing plate 81 near the right side, which matches the output shaft of the second servo motor 84. The output shaft of the second servo motor 84 passes through and is rotatably connected in the hole. The output end of the second servo motor 84 is fixedly connected to the right end of the bidirectional lead screw 82.
[0034] The two movable plates 85 have holes on their right sides that match the limiting rod 83. The two movable plates 85 are slidably connected to the surface of the limiting rod 83 through the holes. The limiting rod 83 limits the two movable plates 85, so that the two movable plates 85 move towards each other as the lead screw rotates.
[0035] Two fixed plates 81 have grooves on one side that match the movable frame 86, and the movable frame 86 is connected to the grooves by sliding left and right through the surface of the grooves. Two rubber clamps 87 are located above the placement seat 7, and the air monitor 3 is located on the top of the placement seat 7.
[0036] Example 2
[0037] Please see Figure 1-3 Furthermore, based on Embodiment 1, a height adjustment mechanism 4 is obtained.
[0038] The height adjustment mechanism 4 includes a fixed base 41, which is fixedly connected to the top of the base 1. A first fixed frame 42 is fixedly connected to the top of the fixed base 41. Guide rods 43 are symmetrically fixedly connected to the top of the fixed base 41. Lifting frames 44 are slidably connected to the surfaces of the two guide rods 43. Racks 45 are fixedly connected to the upper and lower sides of the inner wall of the lifting frame 44 near the back. A second fixed frame 46 is fixedly connected to the left and right sides of the first fixed frame 42 near the top. A rotating shaft 47 is rotatably connected to the left and right sides of the inner wall of the second fixed frame 46. A gear 48 is fixedly connected to the middle of the surface of the rotating shaft 47. A first servo motor 49 is fixedly connected to the right side of the second fixed frame 46.
[0039] The top of the guide rod 43 is fixedly connected to the top of the inner wall of the first fixed frame 42. The top of the first fixed frame 42 has a groove that matches the lifting frame 44, and the surface of the lifting frame 44 is penetrated and slidably connected to the groove.
[0040] The second mounting bracket 46 has a hole on its right side that matches the output shaft of the first servo motor 49, and the surface of the output shaft of the first servo motor 49 passes through and is rotatably connected to the hole.
[0041] The output end of the first servo motor 49 is fixedly connected to the right end of the rotating shaft 47, and the gear 48 meshes with the rack 45.
[0042] The top of the first fixing bracket 42 is provided with a groove near the back, and the rack 45 is located in the groove.
[0043] The top of the lifting frame 44 is fixedly connected to the bottom of the lifting base 5.
[0044] In actual operation, when this device is in use, the symmetrically mounted casters 2 on the bottom of the base 1 utilize their unique steering structure to allow the device to move freely forward, backward, left, right, and in turns on the ground. Operators only need to push the device, and the casters 2 will respond flexibly, quickly moving the device to different monitoring areas for convenient monitoring of diverse environments. After placing the air monitor 3 on top of the placement seat 7, the second servo motor 84 is activated. The second servo motor 84 drives the bidirectional lead screw 82 to rotate. Because the left and right sections of the thread on the surface of the bidirectional lead screw 82 rotate in opposite directions, the two moving plates 85, threadedly connected to the bidirectional lead screw 82, will move axially along the limiting rod 83 under the limiting action of the limiting rod 83. Since the moving frame 86 movably fixes the plate 81, the moving plate 85 can drive the rubber clamp 87 to move synchronously through the moving frame 86 until the rubber clamp 87 clamps and fixes the air monitor 3. The limiting rod 83 and the groove on the fixed plate 81 guide and limit the moving plate 85 and the moving frame 86 respectively, ensuring that the rubber clamp 87 clamps the monitor smoothly and accurately, preventing it from shaking or shifting during device operation. When it is necessary to disassemble the monitor, the second servo motor 84 is started in reverse to release the rubber clamp 87. When it is necessary to adjust the height of the air monitor 3, the first servo motor 49 is started. The output shaft of the first servo motor 49 drives the rotating shaft 47 to rotate, and the gear 48 fixed on the rotating shaft 47 rotates accordingly. Since the gear 48 meshes with the rack 45 on the inner wall of the lifting frame 44, the rotation of the gear 48 is converted into the up and down movement of the rack 45. At the same time, the lifting frame 44 slides steadily up and down along the groove on the top of the first fixed frame 42 under the guidance of the guide rod 43 through sliding cooperation with the guide rod 43, thereby driving the lifting seat 5, the placement seat 7 and the air monitor 3 to rise and fall synchronously, realizing precise adjustment of the monitoring height to adapt to the needs of different monitoring scenarios.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
