Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a greenhouse gas monitoring platform. Background Technology

[0002] Currently, air quality monitoring in my country mainly focuses on the concentrations of nitrogen oxides, ozone, carbon monoxide, sulfur dioxide, PM2.5, and PM10, which cannot accurately reflect the concentrations of greenhouse gases in the air or monitor the progress of dual-carbon initiatives. This invention utilizes existing urban infrastructure to install a greenhouse gas monitoring platform next to lampposts to monitor greenhouse gas levels. This provides scientific data support for exploring the patterns of greenhouse gas concentration changes under different weather conditions and at different times, thereby contributing to achieving dual-carbon goals and mitigating global warming.

[0003] Utility model patent CN 220957687 U discloses an atmospheric monitoring device based on a light pole. This device uses the light pole as its support base, requiring manual adjustment of the device's height and angle, as well as manual installation and removal from the light pole, making the operation cumbersome. Furthermore, the design of the two ring-shaped components fixed to the light pole does not take into account the pole's tapered shape, leading to stress concentration and potential damage to the pole's surface due to line contact. To address this issue, this utility model designs a greenhouse gas monitoring platform. This platform can automatically change the height and direction of greenhouse gas monitoring to obtain more comprehensive and accurate data. It can also quickly connect and disconnect from the light pole via electromagnetic force for stable and reliable support. The overall structure is foldable for easy storage and transportation. Utility Model Content

[0004] The purpose of this invention is to provide a greenhouse gas monitoring platform. This platform utilizes a two-stage gear and rack mechanism to achieve a large-stroke height adjustment, and a turntable mechanism to achieve omnidirectional adjustment of the detection direction. Changes in detection height and direction are automatically adjusted by a motor drive, and the platform can be programmed to detect greenhouse gas concentrations at different heights and angles according to detection requirements. The electromagnetic claw's fixing rod is hinged to the support platform via a hinge shaft, allowing adjustment of the claw's pitch to adapt to the shape of the lamp post, which is thinner at the top and thicker at the bottom. Electromagnetic force allows for quick fixation to the lamp post, and the three legs achieve force balance via pull rods. The feet can be angled via hinge shafts, ensuring stable contact with the ground.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A main beam is mounted on a turntable mechanism; a first lifting mechanism moves up and down along the main beam using a rack and pinion mechanism; a second lifting mechanism moves up and down along the first lifting mechanism using a rack and pinion mechanism; a greenhouse gas monitor is mounted on the second lifting mechanism; and the two-stage lifting mechanism, combining the first and second lifting mechanisms, achieves the height change of the greenhouse gas monitor. The turntable mechanism enables the change of the greenhouse gas monitor's detection direction.

[0006] Preferably, the turntable motor is fixed below the support platform, the turntable is coaxial 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 its first lifting mechanism, second lifting mechanism and atmospheric environment monitoring instrument to rotate together, so as to realize the change of orientation of the greenhouse gas monitoring instrument.

[0007] Preferably, when the three outriggers are extended, the angle of the outriggers is changed by the hinge pin, ensuring full contact between the bottom surface of the outriggers and the ground. When the three outriggers are opened to their maximum extent, the pull rod hinged to the ring-shaped component pulls the outriggers, limiting their opening angle. The fixing rod connected to the electromagnetic claw is hinged to the support platform via a hinge pin. The angle between the fixing rod and the horizontal plane can be adjusted by the fixing rod hinge pin to adapt to the characteristic of the lamp post being thinner at the top and thicker at the bottom, ensuring full contact between the surface of the electromagnetic claw and the surface of the lamp post. The electromagnetic claw is V-shaped, and the strip electromagnet on its working surface is 0.3mm~0.5mm lower than the buffer pad. This ensures that the contact surface between the electromagnetic claw and the lamp post is the surface of the buffer pad rather than the surface of the strip electromagnet, avoiding wear and damage to the lamp post surface caused by the strip electromagnet, while also ensuring that the electromagnetic attraction generated by the strip electromagnet firmly fixes the electromagnetic claw to the surface of the lamp post.

[0008] Preferably, when the annular component is pulled upwards to its limit, the three pull rods fold and retract into the slot between the three support legs, at which point the three support legs are brought together. The magnetic adsorption fixing mechanism rotates and folds around the hinge axis of the fixing rod, resting against the brought-together support legs. At this point, the equipment is in a folded and stored state, facilitating storage and transportation.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1) The first lifting motor 201 of the first lifting mechanism 2 of the greenhouse gas monitoring platform transmits power to the first lifting beam 203 via the first gear drive 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 support frame 306 and the greenhouse gas monitor 1 on it to rise or fall, causing the greenhouse gas monitor 1 to change height. This two-stage lifting mechanism not only increases the range of height adjustment of the greenhouse gas monitor 1, but also allows it to be retracted into a smaller space when storage is required.

[0011] 2) The output shaft of the turntable motor 502 of the greenhouse gas monitoring platform drives the turntable 501 to rotate around the axis of the support platform 601, thereby driving the main beam 4 and its first lifting mechanism 2, second lifting mechanism 3 and greenhouse gas monitor 1 to rotate together, which can change the orientation of the greenhouse gas monitor 1. The adjustment of the height and orientation of the greenhouse gas monitor 1 is achieved by motor drive, without manual intervention, realizing the automation of operation and improving the comprehensiveness and accuracy of greenhouse gas monitoring data.

[0012] 3) The three tie rods 609 of the platform support 6 of the greenhouse gas monitoring platform will fold and retract into the middle slot of the three legs 603. At this time, the three legs 606 are together, and the magnetic adsorption fixing mechanism 7 rotates around the hinge axis 701 of the fixing rod and folds 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 greenhouse gas monitoring platform can adjust the pitch angle of the fixing rod 702 through the fixing rod hinge 701 to adapt to the characteristics of the lamp post 8 being thinner at the top and thicker at the bottom, so that the surface of the electromagnetic claw 703 and the surface of the lamp post 8 are in full contact.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1 In this embodiment, a greenhouse gas monitoring platform includes a greenhouse gas 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, enabling real-time monitoring of greenhouse gas concentrations at different heights and directions. The main beam 4 is mounted on the turntable mechanism 5. The first lifting mechanism 2 moves up and down along the main beam 4, and the second lifting mechanism 3 moves up and down along the first lifting mechanism 2. The greenhouse gas monitor 1 is mounted on the second lifting mechanism 3. The turntable mechanism 5 changes the detection angle of the greenhouse gas monitor 1, and the combination of the second lifting mechanism 3 and the first lifting mechanism 2 changes the detection height of the greenhouse gas monitor 1. The three legs 603 of the platform support 6 are supported on the ground, and the electromagnetic claws 703 of the magnetic adsorption fixing mechanism 7 are adsorbed onto the surface of the light pole 8, achieving stable support for the greenhouse gas monitoring platform.

[0023] Please see Figure 2 In this embodiment, the first gear support 204 is mounted on the main beam 4, the first lifting motor 201 is mounted on the first gear support 204, the first gear drive shaft 205 is mounted in the shaft hole of the first gear support 204, the first gear 206 is mounted on the first gear drive shaft 205, and the first lifting motor 201 is coaxial with the first gear drive shaft 205 and the first gear 206. The first rack 202 is mounted on the first lifting beam 203, which 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 drive shaft 205, the first gear 206, and the first rack 202. The highest position of the first lifting beam 203 rising along the main beam 4 is limited by the lower edge of the first gear support 204 blocking the lower limit plate 208 of the first lifting beam; the lowest position of the first lifting beam 203 falling along the main beam 4 is limited by the upper edge of the first gear support 204 blocking the upper limit plate 207 of the first lifting beam.

[0024] Please see Figure 3 In this embodiment, the greenhouse gas monitor 1 is mounted on the lifting support frame 306, the second gear support 305 is mounted on the lifting support frame 306, and the second lifting motor 302 is fixed on the second gear support 305. The lifting support frame 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 drive shaft 303 and the second gear 304. The second lifting motor 302 transmits power to the second lifting beam 301 through the second gear drive 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 causing the lifting support frame 306 and the greenhouse gas monitor 1 on it to change in height. The upper limit of the height is limited by the obstruction of the upper edge of the lifting support frame 306 by the upper limit plate 308 of the second lifting beam, and the lower limit of the height is limited by the obstruction of the lower edge of the lifting support frame 306 by the lower limit plate 309 of the second lifting beam.

[0025] Please see Figure 4In this embodiment, the turntable motor 502 is fixed on the support platform 601, and the turntable 501 is coaxially fitted with the support platform 601. The main beam 4 is fixed on the turntable 501. 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 its first lifting mechanism 2, second lifting mechanism 3, and greenhouse gas monitor 1 to rotate together, which can change the orientation of the greenhouse gas monitor 1. The support platform 601 is hinged to the support leg 603 through the first hinge pin 602, the support leg 603 is hinged to the support foot 606 through the third hinge pin 605, the support leg 603 is hinged to the tie rod 609 through the second hinge pin 604, and the tie rod 609 is hinged to the ring member 607 through the ring member hinge pin 608. When the three support legs 603 are deployed, the angle of the support foot 606 can be changed by relying on the third hinge pin 605 so that its bottom surface contacts the ground. When the three outriggers 603 are opened to their maximum extent, the annular component 607 transmits the tension to the outriggers 603 via the tie rod 609, limiting their opening angle. At this time, the weight of the equipment itself and the tension of the three tie rods 609 are in a balanced state. The fixed rod 702 is hinged to the support platform 601 via the fixed rod hinge pin 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~0.5mm lower than the working surface of the buffer pad 705. This ensures that the contact surface between the electromagnetic claw 703 and the lamp post 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 post 8, and also ensures that the electromagnetic attraction generated by the electromagnetic claw 703 can firmly fix it to the surface of the lamp post 8. The electromagnetic claw 703 can adjust the pitch angle of the fixed rod 702 through the fixed rod hinge 701, which can adapt to the characteristics of the lamp post 8 being thinner at the top and thicker at the bottom, so that the surface of the electromagnetic claw 703 and the surface of the lamp post 8 can make full contact.

[0026] Please see Figure 4 and Figure 5 In this embodiment, when the annular component 607 is pulled upwards or downwards to its limit position, the three pull rods 609 will fold and retract into the central slot of the three support legs 603, at which point the three support legs 606 will come together. The magnetic adsorption fixing mechanism 7 rotates around the hinge axis 701 of the fixing rod and folds to bring the support legs 606 together. At this time, the device is in a folded storage state, occupying minimal space, which is convenient for storage and transportation.

[0027] In summary, this utility model presents a greenhouse gas monitoring platform that, through an electromagnetic connection with a roadside lamppost, can be conveniently and reliably supported on the ground next to the lamppost. The platform can rotate 360 ​​degrees and achieve height adjustment via two sets of gear and rack mechanisms in a cascaded manner. This allows the greenhouse gas monitor to achieve significant height and omnidirectional angle changes, resulting in more comprehensive and accurate data on greenhouse gas concentrations in the air.
