The wind transmission mechanism 30 is connected to the shielding shell 21, and the wind transmission mechanism 30 can drive the shielding shell 21 to move, so that the shielding shell 21 switches from the shielding position to the connecting position. The first elastic reset member 40 is arranged between the shielding shell 21 and the connecting member 22, so that the shielding shell 21 is kept in the shielding position. The monitor 50 is arranged in the second installation cavity 211 to detect multiple substances in the airflow. Through the above-mentioned setting, when the airflow flows, it can drive the wind transmission mechanism 30 to move, and then the wind transmission mechanism 30 can drive the shielding shell 21 to move, and then the shielding shell 21 can switch from the shielding position to the connecting position, that is, the first air inlet channel 12 is connected with the connecting channel 212, and the airflow can enter the second installation cavity 211 through the first air inlet channel 12 and the connecting channel 212. When the airflow passes through the monitor 50, the monitor 50 can monitor multiple substances in the airflow to realize the monitoring of harmful substances, that is, the airflow can be conducted through the wind transmission mechanism 30, which is convenient for the monitor 50 to monitor harmful substances in the airflow.

The plurality of driving hemispherical shells 32 are arranged at intervals along the circumference of the connecting rod 31 at the second end of the connecting rod 31. Each driving hemispherical shell 32 is provided with a concave cavity 321. When the airflow flows through, the driving hemispherical shell 32 can be driven to rotate through the concave cavity 321, and then the driving hemispherical shell 32 can drive the connecting rod 31 to rotate, and then the connecting rod 31 can drive the shielding shell 21 to rotate.

[0045] like Figure 2 and Fig.16 As shown, in this embodiment, the environmental monitoring device further includes an annular slide rail 60 connected to the connecting member 22, and the shielding structure 20 further includes a first inner convex block 23 connected to the shielding shell 21.

When the airflow passes through the partition 90, the partition 90 is in the conduction state and the partition 90 opens the second air outlet channel 82.

The support structure 120 can support the mounting shell 10. There is a preset distance between the mounting shell 10 and the bottom of the support structure 120, so that the airflow can flow out of the environmental monitoring device more easily through the first air outlet channel 13.

[0059] The support structure 120 includes a plurality of support rods 121 , and the plurality of support rods 121 are evenly spaced apart along the circumferential direction.

The third air outlet channel 911 includes a plurality of air outlet slots, and the plurality of air outlet slots are uniformly and obliquely arranged, and the air outlet slots are arc-shaped air outlet slots.

[0061] The communication channel 212 also has a plurality of air inlet openings arranged at intervals, and the plurality of air inlet openings are evenly arranged on the shielding shell along the circumferential direction.

[0062] The shielding shell 21 covers the outside of the air inlet cylinder 80. The shielding shell 21 rotates to control the opening and closing of the first air inlet channel 12.

Initially, the shielding shell 21 blocks the first air inlet channel 12 of the mounting shell 10, the first inner protrusion 23 contacts the trigger button 70, and the monitor 50 is in a closed state. When the industrial site is windy, the airflow can blow the wind transmission mechanism 30 to rotate, and the rotation of the wind transmission mechanism 30 can drive the shielding shell 21 to rotate, the first elastic reset member 40 is compressed, and the shielding shell 21 no longer blocks the air inlet of the mounting shell 10 after rotation. When the shielding shell 21 rotates, the first inner protrusion 23 is also driven to disengage from the trigger button 70, and the monitor 50 is started, so as to monitor the substances carried by the wind in the mounting shell 10, thereby monitoring the harmful substances therein, and the content of each substance monitored, and the data at the monitoring place can be transmitted to the external terminal device for display.

The airflow and substances passing through the monitor 50 can be discharged through the wind guide frame 130 and then through the conduction plate 84. After the shielding shell 21 is reset, it blocks the air inlet of the mounting shell 10 to prevent dust from the industrial site from entering the mounting shell 10 and polluting the monitor 50. In this way, when the wind blows, the airflow can carry various substances from the industrial site into the mounting shell 10 for monitoring, and when monitoring, only the wind needs to blow. , the gas can be monitored without manual control, which is more convenient to operate; at the same time, as long as the wind blows, no matter what the wind direction is, the wind transmission mechanism 30 can be blown to rotate, thereby rotating the shielding shell 21 and no longer blocking the air inlet, so that the shielding shell 21 can be opened immediately when the wind blows, and the substances entrained in the airflow blown by different wind directions can be detected, which takes less time and enables the device to detect the industrial site environment more quickly and accurately; during monitoring, the torque sensor 140 can detect the size of the rotational torque of the wind transmission mechanism 30 when the wind is blown by the wind.

[0064] The operating member 112 includes a diamond rod 1121 and a knob 1122. The diamond rod 1121 is rotatably disposed in the fixing seat 113. The knob 1122 is slidably disposed on the diamond rod 1121. The adjustment mechanism 110 also includes a third elastic reset member 115 and a gear 116, and the gear 116 is disposed at the bottom of the diamond rod 1121.

[0065] A third elastic reset member 115 is connected between the bottom of the knob 1122 and the inside of the fixed seat 113. The third elastic reset member 115 is a tension spring. The third elastic reset member 115 is rotatably connected to the knob 1122. The gear 116 is meshed with the arc-shaped rack 1112. A stopping structure 114 is provided between the fixed seat 113 and the knob 1122 for locking the knob 1122 to prevent the knob 1122 from rotating at will.

[0066] like Figure 8 and Fig. 9 As shown, in this embodiment, the stopping structure 114 includes a stopping protrusion 1141, the bottom of the knob 1122 is provided with stopping protrusions 1141 evenly spaced along the circumferential direction, and the top of the fixing seat 113 is provided with stopping recesses 1142 evenly spaced along the circumferential direction, the number of the stopping recesses 1142 is consistent with the number of the stopping protrusions 1141, the distance between every two stopping recesses 1142 is consistent with the distance between every two stopping protrusions 1141, and the stopping protrusion 1141 can be stuck in the stopping recess 1142 to fix the knob 1122.

[0067] Before using the environmental monitoring device of this embodiment, you can first pull the knob 1122 to move upward, the third elastic reset member 115 is compressed, and then turn the knob 1122 to drive the diamond rod 1121 to rotate, the diamond rod 1121 rotates to drive the gear 116 to rotate, the gear 116 rotates to poke the arc rack 1112 to move, and the arc rack 1112 can drive the guide block 1111 to move when moving, and the movement of the guide block 1111 causes the first elastic reset member 40 to be compressed. After being compressed to a suitable range, pull the knob 1122 downward to reset, and the third elastic reset member 115 is also reset accordingly, and the knob When 1122 is reset, the stop protrusion 1141 thereon is engaged with the stop recess 1142 on the fixing seat 113, so that the knob 1122 cannot rotate at will. In this way, the first elastic reset member 40 can be compressed in advance. The first elastic reset member 40 after pre-compression has a greater elastic resistance, so that the force required to compress the first elastic reset member 40 is greater, and the wind speed required to rotate the wind transmission mechanism 30 is also required to be faster, so as to avoid rotating the wind transmission mechanism 30 for monitoring when there is a small wind, resulting in frequent monitoring and reducing the service life of the monitor 50.

[0068] like Figure 5 , Figure 7 as well as Fig.11As shown, in the present embodiment, the environmental monitoring device further includes a dust shielding mechanism 150 disposed on the mounting shell 10, the dust shielding mechanism 150 includes an elastic membrane 151 and a conical elastic protrusion 152, each air inlet opening of the mounting shell 10 is embedded with an elastic membrane 151, and conical elastic protrusions 152 are evenly spacedly connected to the inner side of the elastic membrane 151, and the shielding shell 21 can rotate to contact the conical elastic protrusion 152, thereby moving the conical elastic protrusion 152 to move the elastic membrane 151 to vibrate.

[0069] The elastic membrane 151 can filter the dust when it is blown in, preventing the dust from entering the mounting shell 10 , and when the shielding shell 21 rotates, it will continuously move the conical elastic protruding rod 152 , thereby making the elastic membrane 151 vibrate and shaking off the dust attached to the elastic membrane 151 .

[0070] The environmental monitoring device also includes a wind pressure plate 160 and a ball bearing. The wind pressure plate 160 is rotatably arranged at the lower part of the interior of the air guide frame 130. A partition plate 91 is rotatably connected to the middle of the bottom of the installation shell 10. The partition plate 91 is located above the conduction plate 84. The partition plate 91 is provided with oblique annular grooves evenly spaced along the circumference. The number of the annular grooves is the same as that of the air outlet grooves. When the annular grooves on the partition plate 91 are aligned with the air outlet grooves on the conduction plate 84, that is, the partition 90 is in the conduction state, the airflow in the installation shell 10 can be discharged. When the annular grooves on the partition plate 91 deviate from the air outlet grooves on the conduction plate 84, that is, the partition is in the separation state, the conduction plate 84 can be blocked to prevent the external airflow from entering through the conduction plate 84. A second elastic reset member 100 is connected between the plate 91 and the mounting shell 10. The second elastic reset member 100 is a torsion spring. A plurality of ball bearings are evenly spaced between the partition plate 91 and the mounting shell 10. The ball bearings can rotate on the partition plate 91 and the mounting shell 10 to assist the rotation of the partition plate 91 and reduce the friction when the partition plate 91 rotates. A slide groove is provided at the bottom of the mounting shell 10, and a slider is provided at the bottom of the partition plate 91. The slider slides in cooperation with the slide groove. When the partition plate 91 rotates, the slider can slide in the slide groove. When the annular through groove on the partition plate 91 is aligned with the air outlet groove on the conduction plate 84, the slider slides to the end of the slide groove to limit the rotation angle of the partition plate 91.

[0071] The wind pressure plate 160 includes a bottom ring plate and wind guide strips spaced apart on the bottom ring plate, and the airflow can drive the wind pressure plate to rotate through the wind guide strips.

[0072] When the wind guide frame 130 guides the wind out, the airflow will pass through the wind pressure plate 160 when the wind blows. When passing through the wind pressure plate 160, the airflow can squeeze the wind pressure plate 160 to rotate. The rotation of the wind pressure plate 160 can drive the partition plate 91 to rotate. The second elastic reset member 100 is compressed. After the partition plate 91 rotates, the annular groove on it is aligned with the air outlet groove on the conduction plate 84. The airflow and the substances it carries can be discharged through the annular groove on the partition plate 91 and the air outlet groove on the conduction plate 84. When all the wind in the mounting shell 10 is discharged, the partition plate 91 is reset under the action of the second elastic reset member 100 to block the air outlet groove on the conduction plate 84, thereby preventing external pollutants from entering the mounting shell 10 through the conduction plate 84.

[0073] The environmental monitoring device also includes a first annular magnet 170 and a second annular magnet 180. The first annular magnet 170 is connected to the bottom of the shielding shell 21, and the second annular magnet 180 is connected to the bottom of the mounting shell 10. The N pole of the first annular magnet 170 faces downward, and the N pole of the second annular magnet 180 faces upward, so that the magnetic poles of the first annular magnet 170 and the second annular magnet 180 repel each other, thereby facilitating the rotation of the shielding shell 21.

[0074] The environmental monitoring device of this embodiment has the following beneficial effects:

[0075] 1. The environmental monitoring device of this embodiment can effectively monitor the airflow blowing from all directions through the airflow blowing into the installation shell 10 when the wind blows. The operator is no longer required to control the intake of gas and adjust the angle, which is more convenient to operate and makes the monitoring of the on-site air environment more timely and efficient.

[0076] 2. When there is no wind or the wind is weak, the environmental monitoring device of this embodiment can block the first air inlet channel 12 through the shielding shell 21 and turn off the monitor 50 at the same time, thereby protecting the monitor 50 in the installation shell 10 and reducing the possibility of damage or contamination of the monitor 50.

[0077] 3. The environmental monitoring device of this embodiment can pre-compress the first elastic reset member 40 so that the pressure applied when squeezing the first elastic reset member 40 is greater, thereby requiring a greater force for the airflow to blow the wind transmission mechanism 30 to rotate, thereby avoiding blowing the wind transmission mechanism 30 to rotate when there is a small wind, causing the monitor 50 to be frequently started, resulting in rapid contamination of the monitor 50 and affecting the service life of the monitor 50.

[0078] 4. The environmental monitoring device of this embodiment can block the conducting plate 84 through the partition 90 to prevent airflow from entering the cylinder 83 through the conducting plate 84 and causing contamination of the monitor 50.
