[0003] In the existing technology, air quality detection equipment is mainly installed on the roof of a house with a fixed bracket. The exposed detection probe monitors pollutants in the air to prevent the concentration of harmful substances in the air from rising and causing harm to nearby residents. However, in extreme weather such as strong winds or heavy rain, the exposed detection probe is easily damaged by rainwater erosion and impacts from external objects. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, the exposed detection probes are easily damaged by rainwater erosion and impacts from external objects during extreme weather conditions such as strong winds or heavy rain. Therefore, an environmental air quality detection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ambient air quality detection device, comprising: a movable rod, a support cylinder provided on the outer surface of the movable rod, a base fixedly connected to the bottom of the support cylinder, and a protective component fixedly connected to the top of the movable rod; a protective component, comprising a first fixed seat, a second fixed seat, and a protective cylinder, a connecting frame symmetrically fixedly connected between the first fixed seat and the second fixed seat, a motor fixedly connected to the bottom center of the second fixed seat, a rotating plate fixedly connected to the output end of the motor, an installation cylinder fixedly connected to the top of the second fixed seat, a detection head provided at the inner bottom of the installation cylinder, a plurality of first through holes equidistantly opened on the outer surface of the installation cylinder, the protective cylinder being disposed on the outer side of the installation cylinder, a plurality of second through holes equidistantly opened on the outer surface of the protective cylinder, an upper ring block fixedly connected to the top of the protective cylinder, a top plate provided on the top of the upper ring block, and fixed rods symmetrically fixedly connected to the bottom of the top plate.

[0006] Preferably, the bottom of the top plate is fixedly connected with multiple insert rods at equal intervals, and all of the insert rods movably penetrate the upper ring block.

[0007] Preferably, both of the fixing rods are movably connected through the rotating plate, and a second nut is threadedly connected to the outer surface of both fixing rods near the bottom.

[0008] Preferably, a plurality of protective nets are equidistantly arranged on the outer surface of the protective cylinder, and the plurality of protective nets are respectively located outside the plurality of second through holes.

[0009] Preferably, a lower ring block is fixedly connected to the bottom of the protective cylinder, and an annular groove is formed at the bottom of the lower ring block.

[0010] Preferably, an annular track is provided at the top of the second fixing seat near the edge, and the annular track is matched with the annular groove.

[0011] Preferably, the outer surface of the mounting cylinder is fitted to the inner surface of the protective cylinder, and the diameters of the first through hole and the second through hole are equal.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, when extreme weather such as strong winds or heavy rain occurs, the motor is started by an external controller. The output end of the motor will drive the rotating plate to rotate horizontally by 45 degrees, so that the protective cylinder will rotate synchronously with the outer surface of the mounting cylinder. This causes the positions of the first and second through holes, which were originally aligned, to become misaligned. The rotated protective cylinder blocks multiple first through holes, keeping the inside of the mounting cylinder in a closed and protected state. This effectively prevents debris in rain, snow, or strong winds from entering the mounting cylinder and damaging the detection head in extreme weather. The protection effect is good, and the service life of the detection head is greatly improved.

[0017] 2. In this utility model, when adjusting the height of the movable rod, guide rails are symmetrically set on the outer surface of the movable rod, and sliding grooves are symmetrically opened on the inner surface of the support cylinder. During the lifting and lowering process of the movable rod in the support cylinder, the guide rails will slide synchronously in the sliding grooves, which plays a limiting role and prevents the position of the movable rod from rotating during the lifting and lowering process, which would cause the position of the adjusting hole and the fixed hole to deviate and make it difficult to align. It is highly practical. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figures 1-7As shown, this utility model provides an ambient air quality detection device, including: a movable rod 1, a support cylinder 2 disposed on the outer surface of the movable rod 1, a base 4 fixedly connected to the bottom of the support cylinder 2, and a protective component 9 fixedly connected to the top of the movable rod 1; the protective component 9 includes a first fixed seat 901, a second fixed seat 902, and a protective cylinder 909, a connecting frame 903 symmetrically fixedly connected between the first fixed seat 901 and the second fixed seat 902, a motor 904 fixedly connected to the bottom center of the second fixed seat 902, a rotating plate 905 fixedly connected to the output end of the motor 904, an installation cylinder 912 fixedly connected to the top of the second fixed seat 902, a detection head 914 disposed at the inner bottom of the installation cylinder 912, a plurality of first through holes 913 equidistantly opened on the outer surface of the installation cylinder 912, the protective cylinder 909 disposed on the outer side of the installation cylinder 912, a plurality of second through holes 918 equidistantly opened on the outer surface of the protective cylinder 909, and an upper... The ring block 917 has a top plate 906 at its top. The bottom of the top plate 906 is symmetrically fixed with fixing rods 907. Multiple insertion rods 919 are equidistantly fixed to the bottom of the top plate 906, all of which movably pass through the upper ring block 917. Two fixing rods 907 movably pass through the rotating plate 905. A second nut 908 is threadedly connected to the outer surface of each fixing rod 907 near its bottom. Multiple protective nets are equidistantly arranged on the outer surface of the protective cylinder 909. 910, multiple protective nets 910 are located on the outside of multiple second through holes 918 respectively. The bottom of the protective cylinder 909 is fixedly connected to a lower ring block 915. The bottom of the lower ring block 915 is provided with an annular groove 916. The top of the second fixing seat 902 is provided with an annular track 911 near the edge. The annular track 911 and the annular groove 916 are matched. The outer surface of the mounting cylinder 912 is in contact with the inner surface of the protective cylinder 909. The diameter of the first through hole 913 is equal to that of the second through hole 918.

[0029] The overall effect of Embodiment 1 is that, when the ambient air quality detection device is used, it is vertically fixed to the outdoor ground or roof via the base 4 type support cylinder 2 and the movable rod 1. The protective cylinder 909 is fitted onto the outside of the mounting cylinder 912, and the annular groove 916 at the bottom of the lower ring block 915 is positioned on the annular track 911. The top plate 906 abuts against the top of the upper ring block 917, aligning the second through hole 918 on its surface with the first through hole 913 on the surface of the mounting cylinder 912. At this time, multiple insertion rods 919 will penetrate the upper ring block 917, and two fixing rods 907 will be tightened by threaded connection of the second nut 908 to the fixing rods 907 after penetrating and inserting into the rotating plate 905. In the event of strong winds or storms... In extreme weather conditions such as rain, the motor 904 is started by an external controller. The motor 904 is fixedly installed at the bottom center of the first fixed base 901. Its output end will drive the rotating plate 905 to rotate horizontally by 45 degrees, so that the protective cylinder 909 will rotate synchronously with the outer surface of the mounting cylinder 912. This will cause the positions of the first through hole 913 and the second through hole 918, which should be aligned, to become misaligned. The rotating protective cylinder 909 will block multiple first through holes 913, so that the inside of the mounting cylinder 912 is in a closed protective state. This can effectively prevent debris in rain, snow or strong winds from entering the mounting cylinder 912 and damaging the detection head 914 in extreme weather conditions. The protection effect is good and the service life of the detection head 914 is greatly improved.

[0030] Example 2: As Figures 1-7 As shown, a fixing hole 6 is provided on the outer surface of the support cylinder 2, and a bolt 3 is provided on the inner surface of the fixing hole 6. A first nut 8 is rotatably connected to the outer surface of the bolt 3. Multiple adjustment holes 5 are provided at equal intervals on the outer surface of the movable rod 1. The fixing hole 6 and the multiple adjustment holes 5 are matched in position. A guide rail 7 is symmetrically fixedly connected to the outer surface of the movable rod 1. A sliding groove 10 is symmetrically provided on the inner surface of the support cylinder 2. The sliding groove 10 is matched with the guide rail 7.

[0031] The overall effect of Embodiment 2 is that, in normal weather conditions, by setting multiple protective nets 910 on the outside of the protective cylinder 909, floating debris can be prevented from entering the installation cylinder 912. When adjusting the height of the movable rod 1, after removing the bolt 3, the movable rod 1 can be pulled upward to a suitable height, so that the adjustment hole 5 at the current position is aligned with the fixed hole 6, and the bolt 3 can be inserted from the fixed hole 6. The first nut 8 is used to connect and lock the bolt 3. By symmetrically setting guide rails 7 on the outer surface of the movable rod 1 and symmetrically opening sliding grooves 10 on the inner surface of the support cylinder 2, the guide rails 7 will slide synchronously inside the sliding grooves 10 during the lifting and lowering of the movable rod 1 in the support cylinder 2, which plays a limiting role and prevents the position of the movable rod 1 from rotating during the lifting and lowering process, which would cause the position of the adjustment hole 5 and the fixed hole 6 to deviate and make it difficult to align. It is highly practical.

[0032] Working principle: When the ambient air quality detection device is in use, it is vertically fixed to the outdoor ground or roof via the base 4 type support cylinder 2 and the movable rod 1. The top of the movable rod 1 is fixedly connected to the first fixed seat 901. The first fixed seat 901 and the second fixed seat 902 are connected together by two connecting brackets 903. The protective cylinder 909 is sleeved on the outside of the mounting cylinder 912, and the annular groove 916 opened at the bottom of the lower ring block 915 is positioned on the annular track 911. The top plate 906 abuts against the top of the upper ring block 917, and the second through hole 918 opened on its surface is aligned with the surface of the mounting cylinder 912. The first through hole 913 is aligned, and multiple insert rods 919 will pass through the upper ring block 917. Two fixing rods 907 will be fastened to the fixing rods 907 by threaded connection using the second nut 908 after passing through and inserting into the rotating plate 905. In extreme weather conditions such as strong winds or heavy rain, the motor 904 is started via an external controller. The motor 904 is fixedly installed at the bottom center of the first fixed base 901, and its output end will drive the rotating plate 905 to rotate horizontally by 45 degrees. This causes the protective cylinder 909 to rotate synchronously against the outer surface of the mounting cylinder 912, aligning the first through hole 913. The positions of 13 and the second through hole 918 are misaligned. The rotating protective cylinder 909 blocks multiple first through holes 913, keeping the interior of the mounting cylinder 912 in a sealed protective state. This effectively prevents debris in extreme weather conditions, such as rain, snow, or strong winds, from entering the mounting cylinder 912 and damaging the detection head 914. The good protective effect greatly extends the service life of the detection head 914. In normal weather, multiple protective nets 910 are installed on the outside of the protective cylinder 909 to prevent floating debris from entering the mounting cylinder 912. When adjusting the height of the movable rod 1, it can be removed... After bolt 3 is in place, pull the movable rod 1 upward to a suitable height so that the adjustment hole 5 and the fixing hole 6 are aligned. Insert bolt 3 into the fixing hole 6 and use the first nut 8 to connect and lock bolt 3 in place. By symmetrically setting guide rails 7 on the outer surface of the movable rod 1 and symmetrically opening sliding grooves 10 on the inner surface of the support cylinder 2, the guide rails 7 will slide synchronously inside the sliding grooves 10 during the lifting and lowering of the movable rod 1 in the support cylinder 2. This plays a limiting role and prevents the position of the movable rod 1 from rotating during the lifting and lowering process, which would cause the position of the adjustment hole 5 and the fixing hole 6 to deviate and make it difficult to align. This method is highly practical.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
