Description

Technical Field

[0001] This utility model relates to the field of air quality detection technology, and in particular to an ambient air monitoring device. Background Technology

[0002] Ambient air monitoring equipment acts as an "invisible sentinel" protecting public health. Through sophisticated sensors, it monitors the concentration of pollutants in the atmosphere in real time. These devices primarily detect key indicators such as PM2.5, PM10, ozone, sulfur dioxide, and nitrogen oxides. Their working principle is similar to that of "chemical scouts," utilizing technologies such as spectral analysis and electrochemical sensing to convert air pollutants into electrical signals, which are then transformed into readable pollution indices through algorithms. Monitoring stations are typically divided into fixed (such as monitoring towers on city rooftops) and mobile (vehicle-mounted monitoring equipment). Some portable devices can also be used for indoor air quality testing. This data not only forms the basis for government air quality reports but also helps track pollution sources, such as factory emissions or traffic pollution, providing a scientific basis for environmental policy formulation. The real-time monitoring network acts like an "air health map," allowing the public to understand the air quality in their area in a timely manner, guiding travel or protective measures, and reducing the risk of pollution exposure.

[0003] Existing technology discloses a miniature ambient air quality monitoring device, including a bracket, a mounting frame sleeved at the top of the bracket, an assembly plate fixed to the end surface of the mounting frame, a sensing component disposed on the surface of the assembly plate, and a fixing rod fixed at each of the four quadrant points at the bottom of the sensing component. One end of the fixing rod passes through the surface of the assembly plate, and a slot is formed on the bottom surface of the fixing rod. This utility model uses a designed stop block, which stops in the bottom slot of the fixing rod, thereby installing and securing the fixing rod, avoiding the inconvenience and easy damage of traditional nut tightening. The designed pull plate facilitates the user to pull and adjust the stop block later. The designed mounting block assembles the connecting block, allowing it to slide and adjust at the bottom of the assembly plate.

[0004] Air quality parameters are displayed on an LED screen installed on the device. However, in areas with harsh environments, such as sandy areas with strong winds, the LED screen is subjected to a large wind load and is also impacted by sand and gravel mixed in with the wind.

[0005] Therefore, it is necessary to provide an ambient air monitoring device to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an ambient air monitoring device that can reduce the damage to LED screens caused by wind load and sand and gravel mixed in the wind.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An ambient air monitoring device includes: a pole with a foundation installed at its lower end and a display screen installed on one side of the pole;

[0009] The pole includes a first pole body and a second pole body, and a connecting rod is provided between the first pole body and the second pole body;

[0010] The foundation includes a base plate that is fixedly installed at the lower end of the upright;

[0011] The display screen includes a display component and a frame for fixing the display component;

[0012] The frame is rotatably mounted on the connecting rod.

[0013] Preferably, the foundation further includes a stabilizing base, which is detachably mounted on the lower end of the base plate, and at least one stabilizing base is provided.

[0014] Preferably, a turntable is rotatably mounted on the connecting rod, and an installation strip is provided on one side of the turntable. The installation strip has a slot, and a hanging plate is fixedly mounted on one side of the frame. The hanging plate can be installed in the slot.

[0015] Preferably, the stabilizer is a rectangular frame, and the stabilizer and the base plate are provided with through holes for bolts to pass through at corresponding positions.

[0016] Preferably, a stop bar is vertically fixed on the turntable, a stop ring is sleeved around the connecting rod, and a protrusion is horizontally fixed on the stop ring, the protrusion being able to contact the stop bar.

[0017] Preferably, the upper end of the second rod is detachably provided with an intermediate rod, and the connecting rod is threadedly connected to the intermediate rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In windy weather, the wind blows on the surface of the display screen and generates a large thrust on the display screen. The display screen rotates under the action of the wind until it is aligned with the wind direction. The two sides of the display screen are evenly stressed and remain aligned with the wind direction. At the same time, the sandpaper mixed in the wind is less likely to hit the display screen, thereby reducing the damage to the display screen.

[0020] (2) The display screen and the mounting strip of this utility model are quick-release structures with a plug-in type. The display screen can be removed by taking the mounting plate out of the slot of the mounting strip. In windy weather, the staff can also directly unplug the power and signal cable of the display screen and remove it from the mounting strip to prevent it from being damaged by the wind.

[0021] (3) This utility model replaces the traditional concrete base with a frame, which makes the construction speed faster. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] First embodiment:

[0028] like Figure 1 An existing ambient air monitoring device includes: a pole 10, which is a circular steel pipe and forms the main body of the device. Various sensors and cameras used for environmental monitoring are installed on the pole 10. A foundation 20 is installed at the lower end of the pole 10, and the foundation 20 is connected to the ground to stably install the device on the ground. A display screen 30 for displaying air quality parameters is installed on one side of the pole 10. The display screen 30 is generally an LED display. The display screen 30 is generally fixed to the pole 10. In windy weather, especially when the wind direction is perpendicular to the display screen 30, a large load is placed on the display screen 30, which can easily lead to its damage. In particular, when the wind carries sand and gravel, the destructive force on the display screen 30 is even greater. Therefore, the following improvements are made to the existing technology.

[0029] Specifically, such as Figure 2 As shown, the upright 10 includes a first rod body 11 and a second rod body 12. Both the first rod body 11 and the second rod body 12 are made of circular steel pipes. The lower end of the first rod body 11 and the upper end of the second rod body 12 are respectively welded and fixed to the upper and lower ends of the connecting rod 13. Therefore, the upright 10 of the device consists of the above three parts.

[0030] The foundation 20 includes a base plate 21 fixedly installed at the lower end of the upright 10. The base plate 21 is horizontally welded and fixed to the lower end of the upright 10. The base plate 21 has through holes for the pins on the concrete base at its lower end to penetrate. After the base plate 21 is fixed on the base, the whole device stands stably on the ground.

[0031] The display screen 30 includes a display component and a frame 31 for fixing the display component. The display component refers to a display assembly containing an LED screen, data cables, controllers, etc., which is mounted on the frame 31 that surrounds it.

[0032] Two sets of turntables 15 containing bearings are fitted onto the connecting rod 13. The shape of the turntables 15 is as follows: Figure 3 As shown, one side of the turntable 15 is a mounting strip 151, which is integral and T-shaped. The inner wall of the bearing is fixed to the connecting rod 13, so the turntable 15 can rotate around the connecting rod 13. On the other hand, a slot-shaped through hole, called slot 152, is opened vertically on the mounting strip 151. The function of slot 152 is to insert the hanging plate 32, which is fixedly installed on the frame 31, into it. The shape of the hanging plate 32 is as follows. Figure 3 As shown, it is L-shaped, with its lower end inserted into the slot 152 and constrained and fixed therein. To further improve the connection stability between the two, second threaded holes 153 are provided at corresponding positions on the sides of the mounting strip 151 and the hanging plate 32. Screws are screwed into the second threaded holes 153 of both. In this way, the frame 31 is fixed on the mounting strip 151 and rotates with the turntable 15. It should be noted that the connecting rod 13 is installed off the central axis of the frame 31. That is, the two parts of the rectangular frame 31 are different sizes with the plane where the connecting rod 13 is located as the dividing point. This prevents the display screen 30 from rotating around the connecting rod 13 as the center under wind load.

[0033] In windy weather, the wind blowing on the surface of the display screen 30 exerts a large thrust on the display screen 30. The display screen 30 rotates under the action of the wind until it is aligned with the wind direction. The forces on both sides of the display screen 30 are balanced and it remains aligned with the wind direction. At the same time, the possibility of sandpaper mixed in with the wind hitting the display screen 30 is smaller, thereby reducing the damage to the display screen 30.

[0034] In addition, the display screen 30 and the mounting strip 151 are a quick-release structure with a plug-in design. The display screen 30 can be removed by taking the mounting plate 32 out of the slot 152 of the mounting strip 151. In windy weather, the staff can also directly unplug the power and signal cables of the display screen and remove it from the mounting strip 151 to prevent it from being damaged by the wind.

[0035] Second embodiment:

[0036] To expedite the installation of the upright 10, the foundation 20 also includes a stabilizer 22, the stabilizer 22 being shaped as follows: Figure 2As shown, the whole is a rectangular frame with the top and bottom ends open. The stabilizing seat 22 is detachably installed on the lower end of the base plate 21. The stabilizing seat 22 and the corresponding position on the base plate 21 are provided with through holes for bolts 23 to pass through. The two are fixed by bolts 23. After digging the pit, the foundation 20 is placed in the pit. Pressure is applied to the upper end of the stabilizing seat 22 to make it penetrate into the soil layer. Finally, the pit is backfilled with soil and compacted. Multiple stabilizing seats 22 can also be stacked to increase the overall height of the stabilizing seat 22, so that it penetrates into the soil layer more deeply. Therefore, the connection between the foundation 20 and the soil layer is more stable.

[0037] By replacing the traditional concrete base with a frame 31, construction can be completed much faster.

[0038] Third embodiment:

[0039] like Figure 2-3 As shown, a stop bar 154 is vertically fixed on the turntable 15. The stop bar 154 rotates with the turntable 15. A retaining ring 16 is sleeved around the connecting rod 13. The retaining ring 16 is annular, and its structure is as follows. Figure 3 As shown, a horizontally oriented protrusion 161 is welded and fixed to one side of the retaining ring 16. The retaining ring 16 also has a screw threaded onto its side wall, which is used to fix it to the connecting rod 13. After loosening the screw, the retaining ring 16 can rotate on the connecting rod 13 to adjust the orientation of the protrusion 161. During the rotation of the display screen 30, the turntable 15 and the protrusion 161 mounted on the turntable 15 rotate. When the protrusion 161 contacts the retaining strip 154, the retaining strip 154 ​​constrains the rotation of the turntable 15. This is to prevent the power cord and data cable connected to the display screen 30 from getting tangled on the support rod 10 due to multiple rotations of the display screen 30. Workers can adjust the direction of the protrusion 161 according to the local wind direction to reduce the contact between the retaining strip 154 ​​and the protrusion 161.

[0040] Fourth embodiment:

[0041] like Figure 2 As shown, the upper end of the second rod 12 is detachably provided with an intermediate rod 14. The lower end of the intermediate rod 14 and the upper end of the second rod 12 are welded to a flange 141 of the same specification, and the two are connected by the flange. The upper end of the intermediate rod 14 is provided with a first threaded hole 142 for the threaded section 131 of the connecting rod 13 to be installed therein. The lower end of the first rod 11 is also provided with a first threaded hole 142 for the connecting rod 13 to be installed therein. In this way, the upright 10 is divided into several detachable and assembleable parts, which facilitates transportation, carrying and on-site assembly.

[0042] In use, the first rod 11, the second rod 12, the connecting rod 13, and the intermediate rod 14 are assembled in sequence. Then, the foundation 20 is installed and buried in the pit. In windy weather, the wind blows on the surface of the display screen 30, generating a large thrust on the display screen 30. The display screen 30 rotates under the action of the wind until it is aligned with the wind direction. The forces on both sides of the display screen 30 are balanced and it remains aligned with the wind direction. At the same time, the possibility of sandpaper mixed in with the wind hitting the display screen 30 is smaller, thereby reducing the damage to the display screen 30.

[0043] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
