[0001] This utility model specifically relates to an angle-adjustable air pollution detection and early warning device, belonging to the field of air pollution detection technology. Background Technology

[0002] Air pollution detection and early warning devices, also known as air quality monitors or atmospheric environment monitors, are precision instruments that use a built-in pump to draw outside air to the vicinity of a highly sensitive detection probe to monitor the concentration of various pollutants in the atmospheric environment in real time.

[0003] Current air pollution detection and early warning devices are mostly installed in fixed locations, which limits their monitoring range and may not be able to fully capture the dynamic changes of local pollution sources, thus affecting the accurate assessment and timely response to pollution situations. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4As shown, an angle-adjustable air pollution detection and early warning device includes a base 1, a support column 2 on the base 1, a detection box 3 mounted on the top of the support column 2, and an air intake pump inside the detection box 3. The air intake pump has an intake pipe 4 connected to its intake end, and the other end of the intake pipe 4 extends into the support column 2 and connects to a multi-way valve 5. Multiple connecting parts of the multi-way valve 5 are connected to flexible hoses 6. An electric actuator 7 is installed inside the support column 2, and a mounting rod 8 is connected to the moving end of the electric actuator 7. A rack 9 is arranged around the mounting rod 8. Multiple sets of grooves are formed inside the support column 2, with each set of grooves having a mounting plate 10 fixedly attached to its edge. One end of the mounting plate 10 is connected to a rotating shaft. The shaft 11 is rotatably connected to a gear 12 that meshes with the rack 9. An adjusting seat 13 is connected to the end of the shaft 11. A swing arm 14 is connected to one end of the adjusting seat 13. The end of the hose 6 away from the multi-way valve 5 is connected to the swing arm 14. The base 1 is the base of the entire device, providing stability and support. The support column 2 connects to and supports the detection box 3 and its internal components. The detection box 3 contains key detection components such as an air pump. The air pump is responsible for extracting air samples and introducing air into the detection probe area inside the detection box 3 through the air suction pipe 4. The multi-way valve 5 diverts the airflow from the air suction pipe 4 to multiple hoses 6 for multi-point sampling. The electric push rod 7 is used to drive the mounting rod 8 and the rack 9 to move up and down.

[0015] During operation, in the initial state, the electric actuator 7 is in the retracted state, the mounting rod 8 and rack 9 are located at the lower position of the support column 2, and the swing arm 14 is connected to the gear 12 through the adjusting seat 13 and the rotating shaft 11. The gear 12 meshes with the rack 9 and is in a stationary state. The hose 6 is connected to the swing arm 14, ready for air sampling. By starting the suction pump in the detection box 3, the suction pump begins to draw ambient air samples through the suction pipe 4. The air samples are delivered to the multi-way valve 5 inside the support column 2 through the suction pipe 4. The multi-way valve 5 diverts the negative pressure from the suction pipe 4. Multiple hoses 6 are connected to ensure that each hose 6 can draw air samples. At the same time, the electric actuator 7 is activated. The moving end of the electric actuator 7 pushes the mounting rod 8 and rack 9 upward. The rise of the rack 9 drives the rotating shaft 11 and the adjusting seat 13 to rotate through the meshing relationship of the gear 12. The rotation of the adjusting seat 13 drives the swing arm 14 to adjust the angle, thereby changing the sampling position of the hose 6. As the swing arm 14 rotates, the hose 6 samples air at different positions, covering a wider monitoring area, so that the suction end of the hose 6 can be adjusted in height and multiple positions.

[0016] Furthermore, a connector 15 is fixedly connected to the end of the swing arm 14 away from the adjusting seat 13. The hose 6 is movably connected to the connector 15. A threaded cylinder 16 is fixedly connected to one side of the connector 15. A screw 17 is threaded inside the threaded cylinder 16, and one end of the screw 17 extends into the connector 15 and abuts against the outside of the hose 6. The hose 6 is connected to the multi-way valve 5 by a rotary joint to support quick disassembly. The abutment and fixation of the hose 6 by the screw 17 improves the stability of the hose 6 on the swing arm 14 and prevents loosening or displacement during rotation and movement. The design of the connector 15 makes the installation and disassembly of the hose 6 simple and convenient.

[0017] Furthermore, a filter screen 18 is installed at the end of the hose 6, and a connecting rod 19 is fixedly connected to the support column 2 in a circumferential manner. Multiple sets of soft brushes 20 are provided on the connecting rod 19. The filter screen 18 is used to filter larger particles and impurities in the air, preventing these substances from entering the hose 6 and the detection box 3, thus extending their service life. The design of the soft brushes 20 allows the hose 6 to be automatically cleaned during movement, reducing the workload of manual maintenance. At the same time, the soft brushes 20 are located in a low position, making it convenient for personnel to perform daily maintenance.

[0018] Furthermore, a first support rod 21 is mounted around the bottom of the support column 2, and a second support rod 22 is hinged to the other end of the first support rod 21. A reinforcing base 23 is fixed to one end of the second support rod 22. A needle 24 is provided at the bottom of the reinforcing base 23. Through the hinged design of the first support rod 21 and the second support rod 22, the device can flexibly adjust the support angle to adapt to uneven ground conditions and provide more stable support. The reinforcing base 23 increases the contact area with the ground, further improving stability. The design of the needle 24 allows the device to obtain additional fixing force on soft ground, reducing movement or tilting caused by soft ground.

[0019] Furthermore, a reinforcing seat 25 is fixedly connected to the top of the support column 2, and the reinforcing seat 25 is connected to the bottom outer wall of the detection box 3; the addition of the reinforcing seat 25 enhances the structural strength of the connection between the support column 2 and the detection box 3, and reduces loosening or deformation caused by long-term use or external vibration.
