[0010] The electric telescopic rod is fixed on an open outdoor ground, and then the air quality sensor head on the monitor performs real-time air quality monitoring of the surrounding environment, and transmits the real-time monitoring information back to the cloud for staff to retrieve the air quality information here at any time.

[0011] Preferably, a wind deflector is fixedly connected to the outer wall of the monitor, and the wind deflector is a quadrilateral plate-shaped structure.

[0012] Preferably, the outer wall of the wind deflector is provided with a protection mechanism, and the protection mechanism comprises a slide bar, one side of the slide bar is fixedly connected to one side of the wind deflector, and the outer wall of the slide bar is slidably connected to a sliding plate.

[0013] Preferably, the sliding plate is a rectangular plate structure, one side of the sliding plate is fixedly connected to a spring B, one end of the spring B is fixedly connected to a magnetic plate B, the outer wall of the sliding bar is fixedly connected to a magnetic plate A, and the outer wall of the magnetic plate A contacts the outer wall of the sliding plate.

[0014] Preferably, the outer wall of the magnetic plate B is slidably connected to the outer wall of the sliding bar, a pressure sensor is fixedly connected to one side of the magnetic plate B, the magnetism of the magnetic plate A and the side opposite to the sliding plate is oppositely attracted, and the magnetism of the sliding plate and the side opposite to the magnetic plate B is oppositely attracted.

[0015] Preferably, a fixing plate is fixedly connected to one side of the slide bar, the fixing plate is fixedly connected to the outer wall of the slide bar, and a central processing unit is fixedly connected to the bottom of the circular disk.

[0016] Preferably, the pressure sensor is electrically connected to a central processing unit, the central processing unit is electrically connected to the electric telescopic rod, and a rotating ball A is rotatably connected to the outer wall of the sliding plate.

[0017] Preferably, the rotating ball A is fixedly connected to a hinged rod, one end of the hinged rod is fixedly connected to a rotating ball B, the outer wall of the rotating ball B is rotatably connected to a lifting and telescopic sleeve, the outer wall of the monitor is fixedly connected to a limiting plate, the inner wall of the limiting plate is slidably connected to a lifting and telescopic sleeve, and the inner wall of the lifting and telescopic sleeve is slidably connected to the outer wall of the monitor.

[0018] The present invention provides an automatic monitoring and sampling device for ambient air quality, which has the following beneficial effects:

[0019] 1. The present invention sets an air quality monitoring mechanism. When the monitor monitors the surrounding air, when air flow occurs in the environment, the wind will blow the monitor, and the monitor controls the monitor to rotate on the circular disk through the wind direction plate on the outer wall. The wind direction plate will follow the wind force to drive the monitor to rotate. The wind direction plate rotates to the rear of the monitor, so that real-time detection and sampling information of the new air there can be performed, thereby avoiding the setting of the air quality sensor head facing a specified direction. When the wind blows from the back, the surrounding environment has been replaced by new air, and because of the obstruction of the monitor, the air in front of the air quality sensor head will cause the air at the air quality sensor head to rotate back and forth due to the turbulence of the air, and cannot be quickly replaced by new air, resulting in the air quality sensor head being unable to update the environmental air quality in real time.

[0020] 2. The present invention provides an air quality monitoring mechanism. When the wind is strong, the monitor is blown, and the circular disk at the bottom of the monitor will bend downward through the elastic force of the spring A between the monitor and the connecting block, so as to avoid damage to the monitor caused by excessive wind. The bent monitor will present an inclined shape, thereby reducing the windward area and effectively avoiding the impact of sand and gravel particles in strong winds, thereby increasing the service life of the monitor as long as possible in the suburbs and reducing the number of inspections by staff who have to travel far away.

[0021] 3. The present invention sets a protective mechanism to pull the retractable lifting and telescopic sleeve to extend and descend, and the two hinged rods on the sliding plate pull the two lifting and telescopic sleeves at the top and bottom of the monitor respectively. As the sliding plate moves away from the monitor, the upper and lower lifting and telescopic sleeves are pulled closer to each other through the hinged rod, thereby completely sealing the outer wall of the monitor, thereby preventing the air quality sensor head and the monitor from being damaged due to excessive impact force of sand and gravel in the air when the wind is very strong. In addition, when the wind is very strong, the air detection effect of the air quality sensor head fluctuates abnormally, and the monitoring value has no reference value. Therefore, the monitor and the air quality sensor head are protected by the lifting and telescopic sleeve at this time, and there is no need to perform monitoring work again during the period, thereby ensuring that the accuracy of the subsequent air monitoring by the monitor and the air quality sensor head is not affected.

[0022] 4. The present invention sets a protection mechanism. As the pressure value received by the central processing unit increases, the electric telescopic rod pulls the telescopic sleeve A and the telescopic sleeve B back into the electric telescopic rod in a proportional manner. The greater the pressure value, the greater the distance the electric telescopic rod pulls back the telescopic sleeve A and the telescopic sleeve B, until the pressure sensor with strong wind force receives the maximum preset value, the central processing unit will make the electric telescopic rod control the telescopic sleeve A and the telescopic sleeve B to be completely retracted into the electric telescopic rod. At this time, the monitor and the circular plate are pulled down by the telescopic sleeve B to escape from the strong wind force above the environment, thereby effectively avoiding the problem of strong wind force in the upper layer of the environment space, reducing damage to the monitor and the electric telescopic rod, the telescopic sleeve A, and the telescopic sleeve B. At the same time, the electric telescopic rod controls the telescopic sleeve A and the telescopic sleeve B to retract, so as to avoid the problem of bending and breaking of the electric telescopic rod, the telescopic sleeve A, and the telescopic sleeve B under the typhoon. The corresponding height is automatically adjusted in real time by adaptive wind force to protect the monitor so that it can monitor the air quality of the environment stably for a long time.

DETAILED DESCRIPTION

[0035] Example 1: Please refer to Figure 1-2 ,The present invention provides a technical solution: an automatic monitoring and sampling device for ambient air quality, comprising an air quality monitoring mechanism 3;

[0036] Air quality monitoring agencies3 include:

[0037] The electric telescopic rod 301 is a hollow columnar structure. The inner wall of the electric telescopic rod 301 is slidably connected to a telescopic sleeve A302, and the inner wall of the telescopic sleeve A302 is slidably connected to a telescopic sleeve B303;

[0038] The connecting block 304 is a circular disc-shaped structure. The bottom of the connecting block 304 is fixedly connected to the top of the telescopic sleeve B303. The top of the connecting block 304 is fixedly connected to a spring A305. The top of the spring A305 is fixedly connected to a circular disc 306. The top of the circular disc 306 is rotatably connected to a monitor 307. The outer wall of the monitor 307 is provided with an air quality sensor head 309.

[0039] The electric telescopic rod 301 is fixed on an open outdoor ground, and then the air quality sensor head 309 on the monitor 307 performs real-time air quality monitoring of the surrounding environment, and transmits the real-time monitoring information back to the cloud for the staff to retrieve the air quality information here at any time;

[0040] Example 2: Please refer to Figure 1-6 , based on the first embodiment, the present invention provides a technical solution: the outer wall of the monitor 307 is fixedly connected with a wind deflector 308, and the wind deflector 308 is a quadrilateral plate structure;

[0041] When the monitor 307 monitors the surrounding air, when air flows in the environment, the wind will blow the monitor 307, and the monitor 307 controls the monitor 307 to rotate on the circular disk 306 through the wind direction plate 308 on the outer wall, and the wind direction plate 308 will follow the wind force to drive the monitor 307 to rotate, and the wind direction plate 308 rotates to the rear of the monitor 307, so that the new air here can be detected and sampled in real time, avoiding the setting of the air quality sensor head 309 facing a specified direction. When the wind blows from the back, the surrounding environment has been replaced by new air, and because of the obstruction of the monitor 307, the air in front of the air quality sensor head 309 will rotate back and forth due to the turbulence of the air, and cannot be quickly replaced by new air, resulting in the air quality sensor head 309 being unable to update the environmental air quality in real time.

[0042] When the wind is strong, the monitor 307 is blown, and the circular plate 306 at the bottom of the monitor 307 will bend downward as a whole with the monitor 307 through the elastic force of the spring A305 between the connecting block 304, so as to avoid damage to the monitor 307 caused by excessive wind. The bent monitor 307 will be inclined, thereby reducing the windward area and effectively avoiding the impact of sand and gravel particles in the strong wind, thereby increasing the service life of the monitor 307 as long as possible in the suburbs and reducing the number of inspections by staff from afar;

[0043] Example 3: Please refer to Figure 1-11 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a protective mechanism 4 is provided on the outer wall of the wind deflector 308, and the protective mechanism 4 includes a slide bar 401, one side of the slide bar 401 is fixedly connected to one side of the wind deflector 308, and a slide plate 402 is slidably connected to the outer wall of the slide bar 401.

[0044] The sliding plate 402 is a rectangular plate structure. A spring B404 is fixedly connected to one side of the sliding plate 402. A magnetic plate B405 is fixedly connected to one end of the spring B404. A magnetic plate A403 is fixedly connected to the outer wall of the sliding bar 401. The outer wall of the magnetic plate A403 contacts the outer wall of the sliding plate 402.

[0045] The outer wall of the magnetic plate B405 is slidably connected to the outer wall of the sliding bar 401, and a pressure sensor 410 is fixedly connected to one side of the magnetic plate B405. The magnetism of the magnetic plate A403 and the opposite side of the sliding plate 402 is that opposite poles attract each other, and the magnetism of the sliding plate 402 and the opposite side of the magnetic plate B405 is that opposite poles attract each other.

[0046] A fixing plate 411 is fixedly connected to one side of the slide bar 401 , and the fixing plate 411 is fixedly connected to the outer wall of the slide bar 401 . A central processing unit 412 is fixedly connected to the bottom of the circular disk 306 .

[0047] The pressure sensor 410 is electrically connected to the central processing unit 412 , the central processing unit 412 is electrically connected to the electric telescopic rod 301 , and the outer wall of the sliding plate 402 is rotatably connected to a rotating ball A406 .

[0048] The rotating ball A406 is fixedly connected to the hinge rod 407, one end of the hinge rod 407 is fixedly connected to the rotating ball B408, the outer wall of the rotating ball B408 is rotatably connected to the lifting telescopic sleeve 409, the outer wall of the monitor 307 is fixedly connected to the limit plate 413, the inner wall of the limit plate 413 is slidably connected to the lifting telescopic sleeve 409, and the inner wall of the lifting telescopic sleeve 409 is slidably connected to the outer wall of the monitor 307;

[0049] At the same time, when the wind is stronger in the suburbs, the force of the sliding plate 402 on the sliding plate 402 is greater than the magnetic attraction between the sliding plate 402 and the magnetic plate A403, so that the sliding plate 402 is separated from the magnetic attraction between the magnetic plate A403, and is blown by the wind to quickly squeeze the spring B404 to deform it, and through the sliding connection between the sliding plate 402 and the sliding bar 401, it slides on the outer wall of the sliding bar 401 close to the direction of the magnetic plate B405, and at the same time, the sliding plate 402 pulls the rotating ball A406, the hinged rod 407, and the rotating ball B408, and the hinged rod 407 realizes the hinged pulling effect between the sliding plate 402 and the lifting and telescopic sleeve 409 through the rotating balls A406 and B408, so that the retractable lifting and telescopic sleeve 409 is pulled to extend and descend, and the two hinged rods 407 on the sliding plate 402 are respectively Pull the two lifting and telescopic sleeves 409 at the top and bottom of the monitor 307. As the sliding plate 402 moves away from the monitor 307, the upper and lower lifting and telescopic sleeves 409 are pulled closer to each other through the hinge rod 407, so that the outer wall of the monitor 307 is completely closed, avoiding the damage to the air quality sensor head 309 and the monitor 307 caused by excessive impact force of sand and gravel in the air when the wind is very strong. In addition, when the wind is very strong, the air quality sensor head 309 has abnormal fluctuations in the air detection effect, and the monitoring value has no reference value. Therefore, at this time, the monitor 307 and the air quality sensor head 309 are protected by the lifting and telescopic sleeves 409, and there is no need to perform monitoring work again during the period, thereby ensuring that the accuracy of the subsequent air monitoring by the monitor 307 and the air quality sensor head 309 is not affected;

[0050] At the same time, when the wind is very strong, as the sliding plate 402 is blown to squeeze the spring B404 to deform it, the spring B404 will synchronously transmit the force to the magnetic plate B405 and the pressure sensor 410 at the rear, and the pressure sensor 410 sends the transmitted pressure value to the central processing unit 412. After the central processing unit 412 receives the pressure value, it sends a command to the electric telescopic rod 301. As the pressure value received by the central processing unit 412 continues to increase, the electric telescopic rod 301 proportionally pulls the telescopic sleeve A302 and the telescopic sleeve B303 back into the electric telescopic rod 301. The larger the pressure value, the greater the distance that the electric telescopic rod 301 pulls back the telescopic sleeve A302 and the telescopic sleeve B303. Until the pressure sensor 410 receives the maximum preset value when the wind is strong, the central processing unit 412 The electric telescopic rod 301 will control the telescopic sleeve A302 and the telescopic sleeve B303 to be completely retracted into the electric telescopic rod 301, so that the monitor 307 and the circular plate 306 are pulled down by the telescopic sleeve B303 and are separated from the strong wind force above the environment, thereby effectively avoiding the problem of strong wind force in the upper layer of the environment space, reducing the damage to the monitor 307 and the electric telescopic rod 301, the telescopic sleeve A302, and the telescopic sleeve B303. At the same time, the electric telescopic rod 301 controls the telescopic sleeve A302 and the telescopic sleeve B303 to retract, so as to avoid the problem of bending and breaking of the electric telescopic rod 301, the telescopic sleeve A302, and the telescopic sleeve B303 under the typhoon, and automatically adjusts the corresponding height in real time by adaptive wind force to protect the monitor 307, so that the air quality of the environment can be stably monitored for a long time.

[0051] In addition, the sliding plate 402 and the magnetic plate B405 have a magnetic attraction, so that even if the wind force received by the sliding plate 402 at the bottom of the space is reduced, the magnetic attraction between the sliding plate 402 and the magnetic plate B405 will maintain the state of squeezing the spring B404, and at the same time maintain the state of pulling the hinged rod 407 to close the lifting and telescopic sleeve 409 to the outer wall of the monitor 307. Only when the wind force is greatly reduced and the sum of the wind force received by the sliding plate 402 and the magnetic attraction between the sliding plate 402 and the magnetic plate B405 is less than the elastic force of the spring B404, the spring B404 will begin to slowly rebound the sliding plate 402 back to the magnetic plate A403. After the sliding plate 402 approaches the magnetic plate A403, the magnetic attraction is maintained again to stabilize it through the magnetic attraction between the sliding plate 402 and the magnetic plate A403, and the upper and lower lifting and telescopic sleeves 409 are pushed open through the hinged rod 407, so that the air quality sensor head 309 on the outer wall of the monitor 307 leaks out to monitor the air quality.

[0052] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
