Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and particularly to an air monitoring platform and a usage method thereof. Background Art

[0002] Road air quality monitoring mainly monitors the concentrations of nitrogen oxides, ozone, carbon monoxide, sulfur dioxide, PM2.5 and PM10 in the air above the road. These polluting gases mainly come from vehicle exhaust emissions and can cause great harm to human health. An air monitoring platform is erected by the roadside to monitor the pollution situation, providing scientific data support for exploring the variation laws of the concentrations of polluting gases in different weather and different time periods, reasonably controlling the traffic flow of each section, and improving the environmental air quality.

[0003] The utility model patent with the publication number of CN 220957687 U discloses an air monitoring device based on a lamp post. The device uses the lamp post as a support base, and the adjustment of the height and angle of the monitoring device needs to be completed manually. The installation and removal of the device on the lamp post also need to be completed manually, and the operation is rather cumbersome. In addition, the external shape design of the two annular parts fixed on the lamp post does not consider the characteristic that the lamp post is thinner at the top and thicker at the bottom, which will cause stress concentration due to line contact and damage the surface of the lamp post. In view of this problem, the present invention designs an air monitoring platform and a usage method thereof. The platform can not only automatically change the height and direction of air monitoring to obtain more comprehensive and accurate monitoring data, but also be quickly connected and disconnected from the lamp post through electromagnetic force to achieve stable and reliable support. The overall structure is foldable, which is convenient for storage and transportation. Summary of the Invention

[0004] The purpose of the present invention is to provide an air monitoring platform and a usage method thereof. The platform uses a two-stage gear-rack mechanism to achieve height adjustment with a large stroke, and uses a turntable mechanism to achieve omnidirectional adjustment of the detection direction. The changes in the detection height and detection direction are both automatically adjusted by a motor, and the detection of the air pollution concentration at different heights and different angles can be completed by program control according to the detection requirements. The fixed rod of the electromagnetic claw is hinged to the support platform through a hinge shaft to adjust the pitch of the electromagnetic claw to adapt to the shape characteristic that the lamp post is thinner at the top and thicker at the bottom. It can be quickly fixed to the lamp post by electromagnetic force. The three legs achieve force balance through tie rods, and the feet can achieve angle adjustment through hinge shafts to stably contact the ground.

[0005] To achieve the above object, the present invention provides the following technical solution: the main beam is installed on a turntable mechanism, the first lifting mechanism is lifted and lowered along the main beam by a gear rack mechanism, the second lifting mechanism is lifted and lowered along the first lifting mechanism by a gear rack mechanism, the atmospheric environment monitor is installed on the second lifting mechanism, and the height change of the atmospheric environment monitor is achieved by a two-stage lifting mechanism combining the first lifting mechanism and the second lifting mechanism. The detection direction of the atmospheric environment monitor is changed by the turntable mechanism.

[0006] Preferably, the turntable motor is fixed under the support platform, the turntable is coaxially matched with the support platform, the main beam is fixed on the turntable, and the output shaft of the turntable motor drives the turntable to rotate around the axis of the support platform, thereby driving the main beam and the first lifting mechanism, the second lifting mechanism and the atmospheric environment monitor thereon to rotate together, so as to realize the change of the direction of the atmospheric environment monitor.

[0007] Preferably, when the three legs are unfolded, the angle of the legs is changed by the hinge shaft so that the bottom surface of the legs is fully in contact with the ground. When the three legs are opened to the maximum extent, the pull rod hinged to the ring member pulls the legs to limit their opening angle. The fixed rod connected to the electromagnetic claw is hinged to the bracket platform through the hinge shaft, and the angle between the fixed rod and the horizontal plane can be adjusted through the fixed rod hinge shaft to adapt to the characteristics of the lamp pole being thin at the top and thick at the bottom, so that the surface of the electromagnetic claw is fully in contact with the surface of the lamp pole. The electromagnetic claw is V-shaped, and the strip electromagnet on its working surface is 0.3mm to 0.5mm lower than the buffer pad. This ensures that the contact surface between the electromagnetic claw and the lamp pole is the surface of the buffer pad rather than the surface of the strip electromagnet, avoiding wear and damage to the surface of the lamp pole by the strip electromagnet, and ensures that the electromagnetic attraction generated by the strip electromagnet firmly fixes the electromagnetic claw on the surface of the lamp pole.

[0008] Preferably, when the ring is pulled upward to the limit position, the three pull rods will fold and retract into the empty slots between the three legs, and the three legs will be close together. The magnetic adsorption fixing mechanism rotates and folds around the hinge axis of the fixing rod and rests on the close legs. At this time, the device is in a folded storage state, which is convenient for storage and transportation.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1) The first lifting motor 201 of the first lifting mechanism 2 of the atmospheric monitoring platform transmits power to the first lifting beam 203 through the first gear transmission shaft 205, the first gear 206 and the first rack 202. The first lifting beam 203 rises or falls along the main beam 4, and the second lifting motor 302 of the second lifting mechanism 3 drives the second gear 304 to climb or move down along the second rack 307, thereby driving the lifting frame 306 and the atmospheric environment monitor 1 thereon to rise and fall, so that the atmospheric environment monitor 1 changes in height. This two-stage lifting mechanism can not only increase the range of height adjustment of the atmospheric environment monitor 1, but also shrink to a smaller space when it needs to be stored.

[0011] 2) The output shaft of the turntable motor 502 of the atmospheric monitoring platform drives the turntable 501 to rotate around the axis of the support platform 601, thereby driving the main beam 4 and the first lifting mechanism 2, the second lifting mechanism 3 and the atmospheric environment monitor 1 thereon to rotate together, and the direction of the atmospheric environment monitor 1 can be changed. The adjustment of the height and direction of the atmospheric environment monitor 1 is achieved through motor drive, without manual participation, realizing the automation of operation, and improving the comprehensiveness and accuracy of atmospheric monitoring data.

[0012] 3) The three pull rods 609 of the platform bracket 6 of the atmospheric monitoring platform will be folded and retracted into the empty grooves in the middle of the three legs 603. At this time, the three legs 606 are close together, and the magnetic adsorption fixing mechanism 7 rotates around the fixed rod hinge shaft 701 to fold close to the legs 603. At this time, the equipment is in a folded storage state, which is convenient for storage and transportation.

[0013] 4) The electromagnetic claw 703 of the magnetic adsorption fixing mechanism 7 of the atmospheric monitoring platform can adjust the pitch angle of the fixed rod 702 through the fixed rod hinge shaft 701 to adapt to the characteristics of the lamp pole 8 being thin at the top and thick at the bottom, so that the surface of the electromagnetic claw 703 is in full contact with the surface of the lamp pole 8.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 , in this embodiment, an air monitoring platform includes an ambient air monitor 1, a first lifting mechanism 2, a second lifting mechanism 3, a main beam 4, a turntable mechanism 5, a platform support 6 and a magnetic adsorption fixing mechanism 7 to realize real-time monitoring of roadside air pollution conditions at different heights and in different directions. The main beam 4 is installed on the turntable mechanism 5. The first lifting mechanism 2 moves up and down along the main beam 4, the second lifting mechanism 3 moves up and down along the first lifting mechanism 2, and the ambient air monitor 1 is installed on the second lifting mechanism 3. The turntable mechanism 5 changes the air detection angle of the ambient air monitor 1, and the combination of the second lifting mechanism 3 and the first lifting mechanism 2 changes the detection height of the ambient air monitor 1. The three legs 603 of the platform support 6 support on the ground, and the electromagnetic claw 703 of the magnetic adsorption fixing mechanism 7 adsorbs on the surface of the light pole 8 to realize stable support of the air monitoring platform.

[0023] Please refer to Figure 2, in this embodiment, the first gear support 204 is installed on the main beam 4, the first lifting motor 201 is installed on the first gear support 204, the first gear transmission shaft 205 is installed in the shaft hole of the first gear support 204, the first gear 206 is installed on the first gear transmission shaft 205, and the first lifting motor 201 is coaxial with the first gear transmission shaft 205 and the first gear 206. The first rack 202 is installed on the first lifting beam 203, and the first lifting beam 203 moves up and down along the track of the main beam 4. The first lifting motor 201 transmits power to the first lifting beam 203 through the first gear transmission shaft 205, the first gear 206 and the first rack 202. The highest position where the first lifting beam 203 rises along the main beam 4 is limited by the blocking of the lower edge of the first gear support 204 against the lower limit plate 208 of the first lifting beam; the lowest position where the first lifting beam 203 descends along the main beam 4 is limited by the blocking of the upper edge of the first gear support 204 against the upper limit plate 207 of the first lifting beam.

[0024] Please refer to Figure 3 , in this embodiment, the ambient air monitor 1 is installed on the lifting carrier 306, the second gear support 305 is installed on the lifting carrier 306, and the second lifting motor 302 is fixed on the second gear support 305. The lifting carrier 306 moves up and down along the second lifting beam 301. The motor shaft of the second lifting motor 302 is coaxial with the second gear transmission shaft 303 and the second gear 304. The second lifting motor 302 transmits power to the second lifting beam 301 through the second gear transmission shaft 303, the second gear 304 and the second rack 307. Since the second lifting beam 301 is fixed to the first lifting beam 203, the second lifting motor 302 drives the second gear 304 to climb or descend along the second rack 307, thereby driving the lifting carrier 306 and the ambient air monitor 1 thereon to change in height. The upper limit of this height is limited by the blocking of the upper limit plate 308 of the second lifting beam against the upper edge of the lifting carrier 306, and the lower limit of this height is limited by the blocking of the lower limit plate 309 of the second lifting beam against the lower edge of the lifting carrier 306.

[0025] Please refer to Figure 4In this embodiment, the turntable motor 502 is fixed on the support platform 601, the turntable 501 and the support platform 601 are coaxially matched, the main beam 4 is fixed on the turntable 501, and the output shaft of the turntable motor 502 drives the turntable 501 to rotate around the axis of the support platform 601, thereby driving the main beam 4 and the first lifting mechanism 2, the second lifting mechanism 3 and the atmospheric environment monitor 1 thereon to rotate together, so as to change the orientation of the atmospheric environment monitor 1. The support platform 601 is hinged to the support leg 603 through the first support leg hinge 602, the support leg 603 is hinged to the support foot 606 through the third support leg hinge 605, the support leg 603 is hinged to the pull rod 609 through the second support leg hinge 604, and the pull rod 609 is hinged to the ring member 607 through the ring member hinge 608. When the three support legs 603 are unfolded, the angle of the support foot 606 can be changed by relying on the third support leg hinge 605 so that its bottom surface contacts the ground. When the three legs 603 are opened to the maximum extent, the ring 607 transmits the pulling force to the legs 603 through the pull rods 609 to limit the opening angle. At this time, the gravity of the equipment itself and the pulling force of the three pull rods 609 are in a balanced state. The fixed rod 702 is hinged to the bracket platform 601 through the fixed rod hinge shaft 701. The electromagnetic claw 703 is installed at the end of the fixed rod 702. The electromagnetic claw 703 is V-shaped. The working surface of the bar electromagnet 704 on the electromagnetic claw 703 is 0.3mm to 0.5mm lower than the working surface of the buffer pad 705. This can ensure that the contact surface between the electromagnetic claw 703 and the lamp pole 8 is the surface of the buffer pad 705 rather than the surface of the bar electromagnet 704, avoiding wear and damage to the surface of the lamp pole 8, and ensuring that the electromagnetic attraction generated by the electromagnetic claw 703 can firmly fix it on the surface of the lamp pole 8. The electromagnetic claw 703 can adjust the pitch angle of the fixed rod 702 through the fixed rod hinge shaft 701, which can adapt to the thin upper and thick lower characteristics of the lamp pole 8, so that the surface of the electromagnetic claw 703 is in full contact with the surface of the lamp pole 8.

[0026] See also Figure 4 and Figure 5 In this embodiment, when the ring member 607 is pulled upward or downward to the extreme position, the three pull rods 609 will be folded and retracted into the empty slots in the middle of the three legs 603, and the three legs 606 will be close together. The magnetic adsorption fixing mechanism 7 rotates around the fixed rod hinge 701 to fold and close the legs 606. At this time, the device is in a folded storage state, which takes up the least space and is convenient for storage and transportation.

[0027] In summary, the atmospheric monitoring platform designed by the present invention can be conveniently and reliably supported on the ground next to the roadside light pole by means of electromagnetic connection and fixation. The monitoring platform can rotate 360 ​​degrees and achieve cascade height adjustment with the help of two sets of gear rack mechanisms, so that the atmospheric environment monitor can achieve a large degree of height change and all-round angle change, making the road air pollution detection data more comprehensive and accurate.
