[0002] With the acceleration of the industrialization and urbanization processes, environmental problems have become increasingly prominent, among which the air quality problem is particularly outstanding. Air quality monitoring can monitor and evaluate the degree of air pollution in real time, providing a scientific basis for taking effective environmental protection measures.

[0003] At present, the main means of air quality monitoring is to establish air quality monitoring stations in the monitoring area. The sampling heads for collecting air are in a bare state. During long-term operation, large particulate dust or debris in the air will accumulate on the surface of the sampling heads, affecting the monitoring accuracy. The patent document with the publication number of CN220626300U in the prior art provides an air quality monitoring device. This device can effectively filter the dust in the air through a dust-proof net, preventing the dust from adhering to the surface of the monitor. A cleaning motor drives a cleaning brush to reciprocate on the surface of the dust-proof net, thereby cleaning the dust on the surface of the dust-proof net.

[0004] In this device, the dust-proof net needs to be cleaned by setting up an additional cleaning system, which increases the usage cost of the structure and the subsequent maintenance cost, and it is difficult for the cleaning brush to effectively clean the side of the dust-proof net facing the windward side. Therefore, there is an urgent need for an online air quality monitoring device based on the Internet of Things to solve the above problems. Summary of the Invention

[0005] In view of the above problems in the prior art that an additional cleaning system needs to be set up for cleaning, which increases the usage cost of the structure and the subsequent maintenance cost, and it is difficult for the cleaning brush to effectively clean the side of the dust-proof net facing the windward side, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide an online air quality monitoring device based on the Internet of Things, aiming to solve the problems that an additional cleaning system needs to be set up for cleaning, which increases the usage cost of the structure and the subsequent maintenance cost, and it is difficult for the cleaning brush to effectively clean the side of the dust-proof net facing the windward side.

[0007] To solve the above technical problems, the present utility model provides the following technical solution: An online air quality monitoring device based on the Internet of Things includes an air quality monitoring station, and further includes a protective housing rotatably connected to the air quality monitoring station. The sampling head of the air quality monitoring station is arranged inside the protective housing. A plurality of wind guide plates are fixedly connected to the top of the protective housing, and a protective cleaning mechanism is installed inside the protective housing.

[0008] The protective and cleaning mechanism includes a dust-proof net. The sampling head of the air quality monitoring station is arranged inside the dust-proof net. On one side of the dust-proof net, two impellers are drivingly connected, and on the other side, a cleaning brush is in frictional contact.

[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification. Embodiment

[0025] Refer to Figures 1-4 , which is the first embodiment of the present invention, provides an air quality online monitoring device based on the Internet of Things. This air quality online monitoring device based on the Internet of Things includes an air quality monitoring station 1, and also includes a protective housing 2 rotatably connected to the air quality monitoring station 1. The sampling head of the air quality monitoring station 1 is arranged inside the protective housing 2. A plurality of air guide plates 3 are fixedly connected to the top of the protective housing 2. A protective and cleaning mechanism 4 is installed inside the protective housing 2;

[0026] The protection and cleaning mechanism 4 includes a dust-proof net 401. The sampling head of the air quality monitoring station 1 is arranged inside the dust-proof net 401. On one side of the dust-proof net 401, two impellers 402 are drivingly connected, and on the other side, a cleaning brush 406 is in frictional contact.

[0027] In the above technical solution, in the case of strong wind, the air deflector 3 is parallel to the air flow direction, making the protection housing 2 face the air directly. When the air enters the protection housing 2, the dust-proof net 401 can intercept large particulate dust or debris in the air, enabling the sampling head to effectively collect air data while avoiding reducing the sampling accuracy. At the same time, the wind drives the impellers 402 to rotate. The impellers 402 drive the dust-proof net 401 to rotate itself, so that the side of the dust-proof net 401 intercepting dust and debris rotates to the side of the cleaning brush 406, and the dust and debris on the surface of the dust-proof net 401 can be removed by the cleaning brush 406.

[0028] A rotating seat 201 is fixedly connected to the bottom of the protection housing 2. A support seat 202 is rotatably connected to the rotating seat 201. The support seat 202 is fixedly connected to the air quality monitoring station 1 through a support frame, and a plurality of balls 203 are rotatably connected to the support seat 202. The balls 203 are in rolling contact with the rotating seat 201.

[0029] In the above technical solution, the cooperation of the balls 203 and the rotating seat 201 improves the rotational smoothness of the protection housing 2, so that when there is strong wind, the air deflector 3 is arranged parallel to the air flow direction, making the air flowing forward at the air inlet end of the protection housing 2, and maximizing the contact between the air and the sampling head.

[0030] It can be understood that with reference to Figure 3 , an inclined guide plate is provided on the side of the impeller 402 close to the dust-proof net 401. The guide plate is fixedly connected to the protection housing 2. The guide plate can guide the air, making it gather and penetrate into the dust-proof net 401, enabling the air to more effectively pass through the surface of the sampling head and facilitating the sampling head to effectively collect air data.

[0031] A gear ring 403 is fixedly connected to the dust-proof net 401. A first drive gear 404 is fixedly connected to the impeller 402. One first drive gear 404 is meshed with the gear ring 403, and a second drive gear 405 is meshed between the other first drive gear 404 and the gear ring 403.

[0032] In the above technical solution, the impeller 402 is composed of a rotating shaft and a plurality of fixing plates. The impeller 402 and the second drive gear 405 are both rotatably connected to the protection housing 2. When the wind drives the impeller 402 to rotate, one first drive gear 404 is directly meshed with the gear ring 403, and the other first drive gear 404 is indirectly meshed with the gear ring 403 through the second drive gear 405, so that the two impellers 402 drive the dust-proof net 401 to rotate.

[0033] Two air inlets 204 are provided on one side of the protective housing 2, and an air outlet 205 is provided at the bottom of the other side.

[0034] In the above technical solution, the impeller 402 is arranged at the corner of the protective shell 2, and the side facing the two impellers 402 is arranged parallel to the air inlet 204, so that the air entering the air inlet 204 can maximize the driving force of the impeller 402 to rotate.

[0035] In some embodiments, in order to make the air inlet 204 of the protective shell 2 better face the wind direction, a counterweight block is provided at the bottom of one side of the protective shell 2 located at the air outlet 205 .

[0036] The cleaning brush 406 is connected and fixed to the protective housing 2 , and the cleaning brush 406 is disposed above the air outlet 205 .

[0037] In the above technical solution, air enters through the air inlet 204 and is discharged through the air outlet 205, forming a directional air flow. When the air flows, the dust and debris cleaned by the cleaning brush 406 can be automatically discharged to the outside.

[0038] During use, the dust net 401 can be set to intercept large particles of dust and debris in the air to avoid sampling interference with the sampling head. When there is a strong wind, the wind force cooperates with the wind guide plate 3 to make the air inlet 204 face the wind direction, so that the flowing air enters the air inlet 204 and drives the impeller 402 to rotate. The impeller 402 drives the dust net 401 to rotate, and the cleaning brush 406 cleans the part in contact with the dust net 401. Under the attraction of wind force and the action of the cleaning brush 406, the dust net 401 can be effectively cleaned, and dust and debris are automatically discharged to the outside with the air. Example

[0039] Reference Figure 2 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a fixing frame 5 is fixedly connected to the protective shell 2 at one side of the air inlet 204, and a plurality of protective rods 501 are fixedly connected inside the fixing frame 5, and the protective rods 501 are arranged obliquely.

[0040] In the above technical solution, the distance from the lower end of the protective rod 501 to the air inlet 204 is smaller than the distance from the upper end of the protective rod 501 to the air inlet 204, so that when larger debris adheres to the surface of the protective rod 501 under the action of wind, when the wind weakens, the debris cannot adhere to the protective rod 501 and falls off automatically.

[0041] The remaining structures are the same as those of Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
