DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 4 An atmospheric pollution monitoring device includes a support base 1, a column 6 is installed on the top of the support base 1, a receiving cavity 2 with an opening on one side is opened at the bottom of the column 6, a controller 3 is installed inside the receiving cavity 2, and the controller 3 is connected to the external power grid through a wire. The controller 3 is a control motherboard or a host.

[0027] like Figure 1 and Figure 2 As shown, a U-shaped block 10 is installed on one side of the top of the column 6. The inside of the U-shaped block 10 is rotatably connected to a cross bar 12, and one end of the cross bar 12 extends to the outside of the U-shaped block 10, so that the cross bar 12 can rotate along the U-shaped block 10.

[0028] like Figure 1 and Figure 2 As shown, fixed blocks 5 are installed on the top and bottom of the column 6, and a screw rod 23 is rotatably connected between the two fixed blocks 5. The top of the screw rod 23 is connected to a drive motor 24, and the drive motor 24 is fixed to the top of one of the fixed blocks 5. The side of the column 6 is also slidably connected to a moving block 7. One end of the moving block 7 is sleeved on the screw rod 23 and threadedly connected to the screw rod 23. The drive motor 24 is connected to the controller 3 through a wire. In actual use, the drive motor 24 can drive the screw rod 23 to rotate, and then drive the moving block 7 to move up and down along the column 6.

[0029] like Figure 1 As shown, the other end of the moving block 7 is equipped with a support rod 8, the top of the support rod 8 extends below the sliding sleeve 13, and the sliding sleeve 13 slides on the cross bar 12, and the bottom of the sliding sleeve 13 is connected to the top of the support rod 8 through a hinge seat. When the moving block 7 moves up and down along the column 6, the support rod 8 will move up and down synchronously, and the rotation angle of the cross bar 12 can be adjusted so that the end of the cross bar 12 away from the column 6 is rotated to the bottom end of the column 6, as shown in FIG. Figure 4 As shown, when the equipment on the cross bar 12 needs to be repaired, the repair is convenient.

[0030] like Figure 2 and Figure 3 As shown, a fixing sleeve 18 is installed at one end of the cross bar 12 away from the U-shaped block 10, and support frames 17 are installed on both sides of the fixing sleeve 18. The top of each support frame 17 extends above the cross bar 12, and the tops of the two support frames 17 are connected by a strip mounting plate 16. At least two detection boxes 15 are installed on the top of the strip mounting plate 16. The two adjacent detection boxes 15 are connected by an air duct 14. An air quality sensor 25 is installed on one side of the interior of each detection box 15. The air quality sensor 25 is connected to the controller 3 through a wire. During actual use, the air quality sensor 25 can detect the air flowing through the detection box 15 and transmit the detection results to the controller 3 for processing.

[0031] It should be noted that a wireless transceiver 28 is also installed inside the accommodating cavity 2. The wireless transceiver 28 is connected to the controller 3 through a wire. The wireless transceiver 28 can support 4G, 5G and local area network communications. After receiving the data transmitted by the air quality sensor 25, the controller 3 can transmit it to the staff's equipment through the wireless transceiver 28 for the staff to understand.

[0032] like Figure 1 and Figure 3As shown, the bottom of the two support frames 17 are both installed with a box 19 through a fixing plate 22, and a plurality of air inlet grooves 27 are opened on one side of the bottom of the box 19. An air pump 26 is installed inside the box 19, and the air outlet end of the air pump 26 is connected to the air outlet pipe 21. One end of the air outlet pipe 21 is fixed to the bottom of the strip mounting plate 16 and is connected to the interior of one of the detection boxes 15. The air pump 26 is connected to the controller 3 through a wire, and an exhaust pipe 29 is installed at the bottom of the detection box 15 away from the air outlet pipe 21. The bottom of the exhaust pipe 29 extends to the bottom of the strip mounting plate 16. In actual use, the air pump 26 sucks external air into the box 19 through the air inlet groove 27, and then transports it to the detection box 15 through the air outlet pipe 21, and the air guide pipe 14 allows the air to flow through multiple detection boxes 15 in sequence, and the air is detected by the air quality sensor 25 arranged in the detection box 15. In this way, the air is detected by multiple air quality sensors 25, which can increase the detection accuracy.

[0033] It should be noted that if Figure 3 As shown, a waterproof edge 20 is installed on the bottom edge of the box body 19, which can block external rainwater and prevent rainwater from flowing into the box body 19 through the air inlet groove 27 to avoid damaging the air pump 26.

[0034] Specifically, when the present invention is in use, when the air quality is detected, the controller 3 controls the air delivery pump 26 to work, and the air delivery pump 26 sucks the external air into the box body 19 through the air inlet groove 27, and then delivers it to the detection box 15 through the air outlet pipe 21. The air in the detection box 15 can flow through all the detection boxes 15 in sequence under the action of the air guide pipe 14. The air quality sensor 25 in each detection box 15 detects the air flowing through and transmits the detection data to the controller 3. The controller 3 then transmits it to the staff's receiving device through the wireless transceiver 28. Detection through multiple air quality sensors 25 can increase the detection accuracy. When the air quality sensor 25 and the air delivery pump 26 need to be repaired, the staff can control the drive motor 24 to work through the controller 3. The drive motor 24 drives the screw rod 23 to rotate, so that the movable block 7 moves downward. Under the action of the support rod 8, the cross bar 12 can be driven to rotate downward along the U-shaped block 10, so that the height of the box body 19 and the detection box 15 can be lowered, which is convenient for maintenance.

[0035] Furthermore, if Figure 1 and Figure 2 As shown, bellows telescopic sleeves 9 are installed at the upper and lower ends of the moving block 7, and the bellows telescopic sleeves 9 are all sleeved on the screw rod 23, and the end of the bellows telescopic sleeves 9 away from the moving block 7 is fixed on the corresponding fixed block 5. The bellows telescopic sleeves 9 can expand and contract with the movement of the moving block 7, and then can sleeve the screw rod 23, isolating the screw rod 23 from the external environment, and preventing the screw rod 23 from being oxidized and corroded by the external environment.

[0036] Furthermore, Figure 2 As shown, there is a distance between the inner surface of the bellows expansion sleeve 9 and the side surface of the screw rod 23, so that the bellows expansion sleeve 9 will not touch the screw rod 23, and the screw rod 23 will not damage the bellows expansion sleeve 9 during the rotation process.

[0037] like Figure 1 As shown, one side of the bottom of the column 6 is connected to a sealing cover 4 through a hinge, the sealing cover 4 covers the opening of the accommodating cavity 2, and the other side of the sealing cover 4 is fixed to the side of the column 6 by a buckle. In actual use, by covering the opening of the accommodating cavity 2 with the sealing cover 4, the controller 3 and the wireless transceiver 28 in the accommodating cavity 2 can be isolated from the external environment, thereby protecting the controller 3 and the wireless transceiver 28.

[0038] Furthermore, Figure 2 As shown, a waterproof cover 11 is installed on the top of the fixed block 5 at the upper end of the column 6, and the drive motor 24 is located in the waterproof cover 11. During actual use, the waterproof cover 11 can separate external rainwater from the drive motor 24, so that the drive motor 24 will not be damaged by moisture.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
