Description

Technical Field

[0001] This utility model relates to the field of air monitoring devices, specifically an air quality detection device for environmental engineering. Background Technology

[0002] Air, the "life gas" we breathe every day, is layered and covers the Earth's surface. It is transparent, colorless, and odorless, and is mainly composed of nitrogen and oxygen. It has a significant impact on human survival and production. Generally speaking, the composition of air is relatively fixed, and air quality testing is an important means of assessing the cleanliness or pollution level of the air.

[0003] Existing air quality monitoring devices are usually fixed in specific outdoor locations. Fixed monitoring devices are prone to problems such as insufficient spatial coverage and delayed response. Existing trolley-type monitoring devices cannot stay in a specific location for a long time because their wheels are not securely locked. Utility Model Content

Four sets of universal wheels 17 are threadedly installed on the lower part of the base 1. By rotating the rotating cap 5, the second bevel gear 4 drives the first bevel gear 3 to rotate. The follower shaft 6 drives the worm gear 7 to rotate. The worm gear 7 drives the worm wheels 8 on both sides to rotate, so that the rotating shaft 9 drives one side of the push plate 10 to rotate. The other end of the push plate 10 moves along the sliding groove 11 through the push rod 12. The connecting pieces 13 on both sides drive the lifting block 14 to move up and down along the lower part of the base 1, so as to realize the retraction and extension of the support plate 15 and the locking and unlocking of the universal wheels 17.

[0021] Two sets of rotating plates 18 are fixedly welded to the upper part of the base 1, and a rotating block 19 is rotatably installed between the rotating plates 18. A motor 20 is installed on the upper flange of the base 1. The power end of the motor 20 passes through the rotating plates 18 and is connected to the rotating block 19 by a coupling. An installation rod 21 is fixedly welded to the upper part of the rotating block 19. A detector 22 is threaded on the upper side of the installation rod 21. The motor 20 drives the rotating block 19 to rotate, thereby driving the vertical and horizontal movement of the installation rod 21, which facilitates the installation and maintenance of the detector 22 by lowering the installation rod 21.

[0022] Working principle: When in use, rotating the rotating cap 5 causes the second bevel gear 4 to drive the first bevel gear 3 to rotate, which in turn drives the worm gear 7 to rotate via the follower shaft 6. The worm gear 7 drives the worm wheels 8 on both sides to rotate, causing the rotating shaft 9 to drive one side of the push plate 10 to rotate. The other end of the push plate 10 moves along the sliding groove 11 via the push rod 12. The connecting plates 13 on both sides drive the lifting block 14 to move up and down along the lower part of the base 1, realizing the raising and lowering of the support plate 15 and the locking and unlocking of the universal wheel 17. By rotating the connecting shaft 23 around the mounting rod 21, the mounting plate 24 is rotated to a direction perpendicular to the mounting rod 21. The motor 20 drives the rotating block 19 to rotate, thereby driving the mounting rod 21 to rotate to a horizontal direction. The buffer pad 25 can support the lowered mounting rod 21, making it convenient to lower the mounting rod 21 for the installation and maintenance of the detector 22.
