[0006] The protective component includes a support column that is movably mounted on the top of the mounting column via a pivot. A wind direction monitor for monitoring wind direction is installed at the top of the support column. Two spaced-apart connecting brackets are installed on both sides of the support column. The bottom of the two connecting brackets away from the support column has the same retaining ring, and the position of the retaining ring corresponds to the position of the mounting hole.

[0007] Furthermore, the support column is fitted with a fixing ring located at the bottom of multiple connecting brackets, and the bottom end of the fixing ring is fixedly connected to the top of the support column. Both ends of the fixing ring have encapsulation grooves on their inner sidewalls, and both encapsulation grooves have sealing plates inside. Two telescopic rods for connecting the support column are installed on the side of the sealing plate away from the encapsulation groove, and a spring is fitted on the outer side of the telescopic rod near the sealing plate. Adjustment grooves are provided on the inner sidewalls of both the front and rear ends of the fixing ring.

[0008] Furthermore, each end of the mounting column has two spaced mounting grooves, and both mounting grooves are connected to the mounting holes. A filter screen is provided between the two mounting grooves. The retaining ring is located on the side of the filter screen away from the mounting column. Magnetic plates are installed on the sides of the mounting grooves at both ends of the filter screen. An adsorption plate is provided on the side of the magnetic plate away from the filter screen. The side of the adsorption plate away from the magnetic plate is fixed to the inner wall of the mounting groove.

[0009] Furthermore, the mounting column has a base at its bottom, and a support shaft is mounted on the top of the base via a bearing. The top of the support shaft is fixed to the bottom of the mounting column. A driven gear is sleeved on the outside of the bottom end of the support column, and a main gear is meshed at one end of the driven gear.

[0010] Furthermore, a sealing cylinder is installed on the top of the base, the sealing cylinder is sleeved outside the support shaft, and both the main gear and the driven gear are located inside the sealing cylinder.

[0011] Furthermore, a servo motor is installed at the top of one end of the encapsulation cylinder, and the output shaft of the servo motor passes through the encapsulation cylinder and is fixed together with the main gear.

[0012] Furthermore, the base has multiple spaced grooves at its bottom, and a screw is installed inside the groove. A roller is mounted on the bottom end of the screw via a bearing, and the bottom end of the roller extends to the outside of the groove.

[0013] The top of the screw penetrates through the base and extends to the top of the base, and the outside of the screw is threadedly connected to the inner wall of the base.

[0014] Furthermore, a knob is installed at the top of the screw, and the knob is located on the top of the base.

[0015] Furthermore, the sealing plate has an L-shaped cross-section, and one end of the sealing plate near the support column extends to the outside of the top of the fixing ring.

[0016] The beneficial effects of this utility model are as follows:

[0017] This real-time ambient air monitoring device provides all-around protection for the air monitor through a retaining ring and a mounting column, ensuring the integrity of the air monitor. At the same time, two sealing plates can be operated to move inward simultaneously to separate from the sealing groove.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0031] Please see Figure 1-6 This utility model provides a technical solution: an ambient air real-time monitoring device, including a mounting column 1, an mounting hole 3 is provided inside the mounting column 1, and an air monitor 4 for monitoring air is provided inside the mounting hole 3, and a protective component for protecting the air monitor 4 is provided outside the mounting column 1.

[0032] The protective component includes a support column 5 that is movably mounted on the top of the mounting column 1 via a rotating shaft. A wind direction monitor 2 for monitoring wind direction is installed at the top of the support column 5. Two spaced connecting brackets 6 are installed on both sides of the support column 5. The bottom of the two connecting brackets 6 away from the support column 5 is provided with the same retaining ring 7. The retaining ring 7 is positioned in a left-right correspondence with the mounting hole 3.

[0033] The support column 5 is fitted with a fixing ring 8 located at the bottom of multiple connecting brackets 6, and the bottom end of the fixing ring 8 is fixedly connected to the top of the support column 5. Both ends of the fixing ring 8 have encapsulation grooves 9 on their inner sidewalls, and both encapsulation grooves 9 have sealing plates 10 inside. Two telescopic rods 11 for connecting the support column 5 are installed on the side of the sealing plate 10 away from the encapsulation grooves 9, and a spring 12 is fitted on the outer side of the telescopic rod 11 near the sealing plate 10. Adjustment grooves 13 are opened on the inner sidewalls of both the front and rear ends of the fixing ring 8.

[0034] In use, the operator monitors the airflow direction using the wind direction detector 2 (model FT-WQX2). Then, the operator moves both sealing plates 10 inwards to separate them from the sealing groove 9. Next, the sealing plates 10 are operated to rotate the support column 5. The support column 5, through the connecting bracket 6, rotates the retaining ring 7. This allows the retaining ring 7 to be misaligned and separated from the mounting hole 3, facilitating air contact with the air monitor 4 (model SKY8000-AQ) within the mounting hole 3, thus enabling the air monitor 4 to monitor the air. After rotation, the operator releases the sealing plates 10, allowing them to move into the adjustment groove 13 with the help of the spring 12. The engagement of the sealing plates 10 and the adjustment groove 13 limits the adjustment of the support column 5 and the retaining ring 7, ensuring the stability of the retaining ring 7.

[0035] In this embodiment: the support column 5 is fitted with a fixing ring 8 located at the bottom of multiple connecting brackets 6, and the bottom end of the fixing ring 8 is fixedly connected to the top of the support column 5. The inner sidewalls at both ends of the fixing ring 8 are provided with sealing grooves 9, and the two sealing grooves 9 are provided with sealing plates 10. Two telescopic rods 11 for connecting the support column 5 are installed on the side of the sealing plate 10 away from the sealing grooves 9, and a spring 12 is fitted on the outer side of the telescopic rod 11 near the sealing plate 10. The inner sidewalls at both the front and rear ends of the fixing ring 8 are provided with adjustment grooves 13.

[0036] The sealing plate 10 is moved outward by the rebound force of the spring 12 on the telescopic rod 11, so that the sealing plate 10 can be moved into the sealing groove 9 or the adjustment groove 13, thereby achieving the effect of limiting and fixing the retaining ring 7 in different positions.

[0037] In this embodiment: two spaced mounting grooves 14 are provided at both ends of the mounting post 1, and both mounting grooves 14 are connected to the mounting holes 3. A filter screen 15 is provided between the two mounting grooves 14. The retaining ring 7 is provided on the side of the filter screen 15 away from the mounting post 1. Magnetic suction plates 16 are installed at both ends of the filter screen 15 corresponding to the side of the mounting groove 14. An adsorption plate 17 is provided on the side of the magnetic suction plate 16 away from the filter screen 15. The side of the adsorption plate 17 away from the magnetic suction plate 16 is fixed to the inner wall of the mounting groove 14.

[0038] The air flowing into the mounting hole 3 is filtered by the filter screen 15 to prevent dust in the air from adhering to the outside of the air monitor 4 and affecting the performance of the air monitor 4. Because the magnetic plate 16 and the adsorption plate 17 are magnetically attached, the filter screen 15 and the mounting column 1 are detachably connected, which makes it easy for the staff to remove the filter screen 15 for cleaning and maintenance.

[0039] In this embodiment: the bottom of the mounting column 1 is provided with a base 18, the top of the base 18 is provided with a support shaft 19 connected by a bearing, and the top of the support shaft 19 is fixed together with the bottom of the mounting column 1. The bottom end of the support column 5 is provided with a driven gear 20, and one end of the driven gear 20 is meshed with a main gear 21.

[0040] Because the bottom end of the support shaft 19 is movably connected to the base 18 through a bearing, the support shaft 19 can rotate and can also rotate the air monitor 4 inside the mounting column 1, so as to facilitate the orientation adjustment according to the air flow direction. Furthermore, because the bottom end of the support shaft 19 is fitted with a driven gear 20, the main gear 21 can drive the support shaft 19 to rotate by meshing with the driven gear 20.

[0041] In this embodiment: a sealing cylinder 22 is installed on the top of the base 18. The sealing cylinder 22 is sleeved on the outside of the support shaft 19, and the main gear 21 and the driven gear 20 are both located inside the sealing cylinder 22.

[0042] By fitting the encapsulation cylinder 22 onto the outside of the driven gear 20 and the main gear 21, the encapsulation cylinder 22 can shield and protect the main gear 21 and the driven gear 20, preventing damage to the main gear 21 and the driven gear 20 from collisions and impacts, and ensuring the performance of the main gear 21 and the driven gear 20.

[0043] In this embodiment: a servo motor 23 is installed at the top of one end of the encapsulation cylinder 22, and the output shaft of the servo motor 23 passes through the encapsulation cylinder 22 and is fixed together with the main gear 21.

[0044] Because the output shaft of the servo motor 23 (model YX3-132M-2) is fixedly connected to the main gear 21, the servo motor 23 can drive the main gear 21 to rotate. The main gear 21 then drives the support shaft 19 to rotate through the meshing driven gear 20. This allows for convenient adjustment of the orientation of the air monitor 4, improving the ease of adjustment for staff.

[0045] In this embodiment: the bottom of the base 18 is provided with a plurality of spaced bottom grooves 24, the bottom grooves 24 are provided with screws 25, the bottom end of the screws 25 is mounted with rollers 26 connected by bearings, and the bottom end of the rollers 26 extends to the outside of the bottom grooves 24.

[0046] The top end of the screw 25 passes through the base 18 and extends to the top of the base 18. The outside of the screw 25 is threadedly connected to the inner wall of the base 18.

[0047] Because the screw 25 is threadedly connected to the base 18, the operator can rotate the screw 25 to adjust the height of the roller 26. This allows the operator to easily adjust the base 18 horizontally according to uneven terrain, improving the stability of this utility model. Furthermore, because the base 18 is supported by the roller 26, the operator can easily push the base 18 to move and adjust it. The operator can also completely retract the roller 26 into the bottom groove 24, thereby increasing the contact area between the base 18 and the ground and ensuring the stability of the base 18.

[0048] In this embodiment: a knob 27 is installed at the top of the screw 25, and the knob 27 is located on the top of the base 18.

[0049] The connection between the knob 27 and the screw 25 allows the operator to rotate the screw 25 by operating the knob 27, thereby improving the operator's ability to adjust the height of the roller 26 by operating the screw 25 and enhancing the operator's ease of operation.

[0050] In this embodiment: the cross-section of the sealing plate 10 is set to L-shape, and the end of the sealing plate 10 near the support column 5 extends to the outside of the top of the fixing ring 8.

[0051] Because the cross-section of the sealing plate 10 is L-shaped, the protruding end of the sealing plate 10 can be easily moved by the staff, which improves the convenience of the staff to move the sealing plate 10 and rotate the support column 5.

[0052] Working principle: The staff moves the utility model to a suitable position for monitoring by using the support of the roller 26. Then, the wind direction detector 2 monitors the air flow direction. The servo motor 23 drives the main gear 21 to rotate. The main gear 21 drives the support shaft 19 to rotate through the meshing slave gear 20. The support shaft 19 then drives the mounting column 1 to rotate, thereby achieving the effect of adjusting the orientation of the air monitor 4.

[0053] Then, move both sealing plates 10 inwards simultaneously to separate them from the encapsulation groove 9. Then, operate the sealing plates 10 to drive the retaining ring 7 connected to the support column 5 to rotate, so that the retaining ring 7 is misaligned and separated from the mounting hole 3, so that air can come into contact with the air monitor 4 in the mounting hole 3, and the air monitor 4 can monitor the air. Then, release the sealing plates 10, so that the sealing plates 10 can move into the adjustment groove 13 with the help of the spring 12. The engagement of the sealing plates 10 and the adjustment groove 13 limits the adjustment of the support column 5 and the retaining ring 7, ensuring the stability of the retaining ring 7.

[0054] Therefore, the air monitor 4 can be fully shielded and protected when not in use by the retaining ring 7 and the mounting post 1, so as to avoid damage to the air monitor 4 by collision and impact. Moreover, the structure of the protective component is simple and can effectively improve the ease of operation.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
