Description

Technical Field

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

[0002] In the field of environmental engineering, air quality monitoring plays a crucial role in assessing environmental quality, protecting public health, and formulating environmental policies. As key equipment for acquiring air quality data, the stable operation and accuracy of air quality monitoring devices are of paramount importance.

[0003] Existing air quality monitoring devices face numerous problems in practical use. On the one hand, severe dust pollution significantly impacts detection accuracy. Foreign objects and debris are easily drawn into the device by the air intake probe, contaminating core components and interfering with the detection process, leading to data inaccuracies and hindering reliable data support for environmental engineering research and decision-making. On the other hand, bird activity greatly interferes with the monitoring device. Birds prefer to perch and nest at high altitudes, making the top of the device their target. Bird droppings, feathers, and other debris easily contaminate the device, and their activity can cause malfunctions. Furthermore, bird nesting materials can clog ventilation openings or affect component operation, significantly reducing the device's operational stability. Utility Model Content

[0004] The purpose of this invention is to provide an air quality detection device for environmental engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a detector body, an mounting plate on the back of the detector body, a support rod at the bottom of the detector body, a base at the bottom of the support rod, an air intake probe at the top of the detector body, a bird-repelling and dust-proof component covering the air intake probe, and a vibration-preventing and foot-falling component at the top of the detector body.

[0006] As a preferred embodiment of this utility model, the bird-repelling and dust-prevention component includes a foreign object shield covering the outside of the air intake probe. A rotating shaft is movably mounted on the top of the foreign object shield via a bearing seat. Several connecting rods are mounted on the outer wall of the rotating shaft. An air scoop is mounted on the top of each connecting rod. A first mounting handle is also mounted on the outer wall of the rotating shaft. The first mounting handle is located below one of the connecting rods. A stud is mounted on the top of the first mounting handle. The stud is fixed to a second mounting handle by a nut. A scraper is mounted on the inner side of the second mounting handle. The scraper is fitted against the outer wall of the foreign object shield. Several studs are mounted on the back of the scraper, and each stud is fixed to the second mounting handle by a nut.

[0007] As a preferred embodiment of this utility model, reflective stickers are provided on both the inner and outer walls of the air scoop.

[0008] As a preferred embodiment of this utility model, the vibration anti-fall-foot assembly includes a movable plate disposed on the top of the detector body, with sliding sleeves disposed on each of the four corners of the movable plate, and guide rods disposed at the positions of several sliding sleeves at the four corners of the top of the detector body, with abutment plates disposed on the top of the guide rods, the guide rods being disposed inside the sliding sleeves, and a compression spring being sleeved on the outer side of each guide rod, the compression springs being abutted between the movable plate and the abutment plates, and support plates symmetrically disposed in the middle of the left and right sides of the movable plate;

[0009] The vibration-prevention anti-fall-foot assembly also includes two pairs of fixed ears, which are symmetrically arranged on both sides of the detector body. Each pair of fixed ears is connected to a rotating shaft via a pair of bearing seats. A cam is symmetrically arranged in the middle of the two rotating shafts, which are located below the support plate. A first sprocket is provided at the tail of one rotating shaft, and a first gear is provided at the tail of the other rotating shaft. A motor is provided on the mounting plate. A second sprocket is provided on the drive shaft of the motor at the position corresponding to the first sprocket. The first sprocket and the second sprocket are connected by a chain drive. A second gear is also provided on the drive shaft of the motor, and the second gear meshes with the first gear.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0011] 1. This utility model uses a filter screen as the foreign object shield, which is cleverly designed to cover the outside of the air intake probe. This effectively intercepts foreign objects and debris from the outside, preventing them from being sucked into the device during operation. This design effectively maintains a clean environment inside the device, ensuring that the core components of the detection device are not blocked or contaminated. This guarantees the accuracy and stability of the detection data, prevents foreign objects from interfering with the detection process, and avoids deviations in detection results due to the accumulation of foreign objects. It provides reliable data support for environmental engineering research and decision-making.

[0012] 2. This utility model uses a blower to drive a rotating shaft to rotate, which in turn drives the first mounting handle and the second mounting handle to rotate in sequence. This causes the scraper connected to the second mounting handle to scrape the outer surface of the foreign object cover. With long-term use of the equipment, foreign objects will inevitably be adsorbed on the surface of the foreign object cover. The continuous scraping of the scraper can remove these debris in a timely and effective manner. This self-cleaning mechanism ensures that the foreign object cover always maintains good air permeability and filtration function, avoids filter clogging due to the accumulation of foreign objects, ensures that the equipment can operate continuously and stably, and reduces the frequency and cost of manual cleaning and maintenance.

[0013] 3. During the rotation of the air scoop, the reflective stickers on its inner and outer walls reflect sunlight in all directions, forming flickering light spots. Birds' visual systems are extremely sensitive to this dynamic and bright light change. The strong reflection will make them instinctively feel uneasy and fearful, thus actively moving away from the equipment. This design effectively prevents birds from roosting and nesting on the equipment, reduces the risk of interference and damage to the equipment caused by bird activity, and ensures the normal operation environment of the air quality detection device.

[0014] 4. The vibration anti-foot-fall component of this utility model is driven by a motor to achieve synchronous and opposite rotation of two rotating shafts, which drives the cam to rotate. When the cam rotates to a specific position, it will push the support plate upward, thereby driving the moving plate to move upward on the guide rod. After the cam disengages from the support plate, the moving plate is quickly pressed down and reset under the action of the compression spring. With the continuous operation of the motor, the moving plate moves up and down repeatedly between the guide rods. This high-frequency reciprocating motion keeps the top of the detector body in an unstable state, preventing birds from nesting or landing on it. This effectively prevents birds from staying on the top of the equipment, avoids pollution of the equipment by bird droppings, feathers and other debris, and prevents equipment failures that may be caused by bird activity, ensuring that the air quality detection device can operate stably in an environment free from bird interference.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figures 1-9 As shown, the present invention proposes an air quality detection device for environmental engineering, which includes an air quality detector that is bird-proof and dust-proof. It mainly consists of a detector body 1, a mounting plate 13 fixed on the back of the detector body 1, a support rod 10 connected to the bottom, a base 11 set below the support rod 10 to provide stable support for the detector, an air intake probe 12 located on the top of the detector body 1 for collecting air samples for detection, and a bird-repelling and dust-proof component 2 on its outer cover. At the same time, a vibration-preventing and anti-falling component 3 is also provided on the top of the detector body 1.

[0027] The core of the bird-repelling and dust-proof component 2 is a foreign object shield 20 that covers the outside of the air intake probe 12. The top of the foreign object shield 20 is movably connected to the rotating shaft 22 via a bearing seat 21, allowing the rotating shaft 22 to rotate flexibly. Several connecting rods 23 are evenly distributed on the outer wall of the rotating shaft 22. Air scoops 24 are installed at the top of the connecting rods 23. Under the action of natural wind, the air scoops 24 are driven by force to rotate the rotating shaft 22. The outer wall of the rotating shaft 22 is also equipped with a first mounting handle 26, which is located below one of the connecting rods 23. A stud 27 is located at the top of the first mounting handle 26. The first mounting nut 211 is fastened to the second mounting handle 28. The scraper 29 is fixed inside the second mounting handle 28. The scraper 29 fits tightly against the outer wall of the foreign object cover 20. There are several studs 210 on the back of the scraper 29. Each stud 210 is fixed to the second mounting handle 28 by the second nut 212 to ensure that the scraper 29 is installed firmly and can effectively scrape dust off the outer wall of the foreign object cover 20. In addition, reflective stickers 25 are attached to the inner and outer walls of the air scoop 24. When the air scoop 24 rotates, the reflective stickers 25 reflect sunlight to achieve the purpose of repelling birds.

[0028] The vibration anti-fall-foot assembly 3 includes a movable plate 32, which is located on the top of the detector body 1. Sliding sleeves 33 are installed at the four corners of the movable plate 32. Guide rods 30 are set at the four corners of the top of the detector body 1 corresponding to the sliding sleeves 33. Abutment plates 31 are installed on the top of the guide rods 30. The guide rods 30 pass through the sliding sleeves 33 and are fitted with compression springs 35 on the outside. The two ends of the springs abut against the movable plate 32 and the abutment plates 31 respectively. Support plates 34 are symmetrically arranged in the middle of the left and right sides of the movable plate 32.

[0029] The vibration anti-foot-fall component 3 also includes two pairs of fixed ears 36, symmetrically distributed on both sides of the detector body 1. Each pair of fixed ears 36 is movably mounted with a rotating shaft 38 via a pair of bearing seats 37. A cam 39 is symmetrically mounted between the two rotating shafts 38, located directly below the support plate 34. One rotating shaft has a first sprocket 310 mounted at its tail, and the other rotating shaft has a first gear 311 mounted at its tail. A motor 312 is fixed on the mounting plate 13. A second sprocket 313 is mounted on the drive shaft of the motor 312 at the position corresponding to the first sprocket 310. The first sprocket 310 and the second sprocket 313 are connected by a chain 315. A second gear 314 is also mounted on the drive shaft of the motor 312. The second gear 314 meshes with the first gear 311. After the motor 312 is started, the power is transmitted sequentially through the drive shaft, causing the two rotating shafts 38 to rotate synchronously and in opposite directions, driving the cam 39 to rotate, thereby realizing the reciprocating up-and-down movement of the moving plate 32 on the guide rod 30 to prevent birds from landing.

[0030] During the daily use of the equipment, the foreign object shield 20 plays a crucial role. It is made of filter material to effectively isolate foreign objects from the outside. When the outside air flows, the debris will be blocked on the outside by the filter, thus ensuring that the air intake probe 12 will not suck foreign objects into the equipment. This not only maintains the clean environment inside the equipment, but also ensures the accuracy and stability of the detection work and avoids deviations in the detection data due to foreign object blockage and interference.

[0031] At the same time, when a natural wind blows, several wind scoops 24 will be affected by the wind force, which will cause the connected rotating shaft 22 to rotate slowly. During the rotation of the wind scoops 24, the reflective stickers 25 pasted inside and outside of them begin to play their role. These reflective stickers 25 are made of highly reflective materials and can reflect sunlight efficiently. Under the illumination of light, the reflective stickers 25 will scatter flashing light spots in all directions. Since birds' visual system is extremely sensitive to such dynamic and bright light changes, the strong reflection will make them instinctively feel uneasy and fearful, thus prompting birds to stay away from the equipment, effectively preventing birds from perching and nesting on the equipment, and reducing the risk of interference and damage to the equipment caused by bird activities.

[0032] As the rotating shaft 22 rotates, it drives the first mounting handle 26 connected to it to rotate synchronously. The first mounting handle 26 is connected to the second mounting handle 28, which in turn drives the second mounting handle 28 to rotate as well. The end of the second mounting handle 28 is connected to a scraper 29. When the second mounting handle 28 rotates, the scraper 29 will perform a detailed scraping operation along the outer surface of the foreign object cover 20. During the long-term operation of the equipment, debris will gradually be adsorbed on the surface of the foreign object cover 20. If it is not cleaned in time, this dust may gradually accumulate, causing the filter to become clogged and affecting the ventilation effect and detection performance of the equipment. The continuous scraping of the scraper 29 can remove these adsorbed debris in a timely and effective manner, so that the foreign object cover 20 always maintains good air permeability and filtration function, ensuring that the equipment can operate continuously and stably.

[0033] During equipment operation, motor 312 starts working, and its power output shaft drives the second sprocket 313 to rotate. The second sprocket 313 is closely engaged with the first sprocket 310 through chain 315, realizing efficient power transmission, thereby driving the right-side rotating shaft 38 to start rotating. At the same time, when motor 312 rotates, the second gear 314 on its output shaft also rotates. The second gear 314 meshes with the first gear 311. The gear meshing structure realizes the conversion and transmission of power, so that the left-side rotating shaft 38 can also rotate synchronously. Under the drive of motor 312, the two rotating shafts 38 achieve synchronous and opposite rotation.

[0034] During the rotation of the rotating shaft 38, the cam 39 fixed on it also rotates. When the two cams 39 rotate to a specific position at the same time, they will push the support plate 34 upward. When the support plate 34 is pushed up, it will drive the moving plate 32 to move upward on several guide rods 30. The guide rods 30 can provide precise guidance for the movement of the moving plate 32, ensuring the stability of the moving plate 32 during the up and down movement. When the cam 39 continues to rotate and disengages from the bottom of the support plate 34, the moving plate 32 will quickly press down and reset under the combined action of several compression springs 35. The compression springs 35 have good elastic properties and can quickly release the stored elastic potential energy after the cam 39 disengages, pushing the moving plate 32 to move downward quickly. Under the continuous operation of the motor 312, the moving plate 32 will continuously move up and down between several guide rods 30. This high-frequency reciprocating motion keeps the top of the detector body 1 in an unstable state, preventing birds from nesting or landing on it, ensuring a clean environment on the top of the equipment, and providing a strong guarantee for the stable operation of the detection equipment.
