Description

Technical Field

[0001] The present invention relates to an atmospheric environment detection device, in particular to an atmospheric environment detection equipment, belonging to the technical field of atmospheric detection. Background Art

[0002] Atmospheric environmental monitoring is the process of measuring the concentration of pollutants in the atmospheric environment, observing and analyzing their changes and impacts on the environment. Atmospheric monitoring is the process of measuring the types and concentrations of pollutants in the atmosphere, observing their temporal and spatial distribution and changing patterns. Air quality monitoring is the sampling and analysis of major pollutants in the atmosphere of a certain area.

[0003] A search revealed that Chinese patent number CN119044413A discloses an atmospheric pollution detector for environmental testing. When the detector is inserted into the testing kit, the power rail on the back of the detector slides and plugs into the power slider, thereby enabling the detector to conduct electricity and transmit data. When the plug-in board is inserted into the limit hole, the back of the detector presses against the limit post, which in turn presses the springs on both sides, thereby inserting the limit post into the plug-in board. When inserted into the limit hole, the springs eject the limit post and press it against the inside of the detector, thereby stabilizing the insertion of the detector. This achieves the effect of detecting multiple atmospheric pollutants and facilitates easy assembly and disassembly of the detector. However, in the aforementioned patented product, the power sliders of each detector and the plug-in board on the testing kit are exposed. In outdoor environmental testing, especially in the northwest region, where wind and sand are strong, external dust can easily adhere to the power slider during installation and removal, causing the detector to malfunction and even damage the entire environmental monitoring device.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1:

[0033] Reference Figure 1-7 An atmospheric environment detection device includes a detection instrument 5, a loading box 8, a hydraulic lifting rod and a chassis. The loading box 8 and the port of the detection instrument 5 are provided with matching contacts. The loading box 8 is provided with a lifting shielding plate 4 and a micro air pump 3. The bottom end of the lifting shielding plate 4 is provided with a transmission component. The upper and lower ends of the detection instrument 5 are provided with gear bars 501.

[0034] When the detection instrument 5 is inserted into the loading box 8, the gear bar 501 at the bottom of the detection instrument 5 will mesh with the transmission component and drive the transmission component to rotate in the forward direction. At this time, the lifting shielding plate 4 will descend, exposing the contacts inside the loading box 8 so that the detection instrument 5 is connected to the inside of the loading box 8;

[0035] When the detection instrument 5 is pulled out from the loading box 8, the gear bar 501 drives the transmission component to rotate in the opposite direction, and the lifting shielding plate 4 rises. When the detection instrument 8 is completely pulled out, the lifting shielding plate 4 is reset to shield the contacts inside the loading box 8. The lifting shielding plate 4 can prevent external wind, sand and dust from affecting the contacts inside the loading box 8.

[0036] The transmission component consists of a rotating gear 402, a rotating rod 405, a first conveyor belt 404, a second conveyor belt 406 and a gear plate 408. The rotating rod 405 is arranged directly below the rotating gear 402. The first conveyor belt 404 is connected to both sides of the central axis of the rotating gear 408 and the rotating rod 405. The second conveyor belt 406 is provided at both ends of the rotating rod 405 and on both sides of the central axis of the gear plate 408. When the rotating gear 402 rotates forward, it will drive the first conveyor belt 404, the second conveyor belt 406 and the gear plate 408 to rotate forward in sequence. The first conveyor belt 404 and the second conveyor belt 406 are arranged alternately.

[0037] In this embodiment, it should be noted that: the loading box 8 is provided with a socket connected to the detection instrument 5, and the number of the sockets is consistent with the number of detection instruments 5 for detecting the atmospheric environment. The detection instrument 5 can be installed in sequence as an ozone detector, a carbon monoxide detector, a nitrogen dioxide detector, a carbon oxide detector, a sulfur dioxide detector, a PM2.5 detector, a PM10 detector and a carbon dioxide detector as needed, thereby detecting atmospheric pollution.

[0038] like Figure 2-4 As shown, the rotating gear 402 is set at the bottom end of the insertion hole of the loading box 8 near the outside, and an insertion rod 403 is provided at the central axis position of the rotating gear 402. Both sides of the insertion rod 403 and the rotating rod 405 are provided with a first conveyor belt 404. The interior of the first conveyor belt 404 is meshed with the insertion rod 403 and the rotating rod 405. A driving rod 407 is provided in the middle of the gear plate 408. The two sides of the driving rod 407 and the rotating rod 405 are provided with a second conveyor belt 406. The interior of the second conveyor belt 406 is meshed with the rotating rod 405 and the outer side of the driving rod 407. When the detection instrument 5 is inserted inward, the gear bar 501 at the bottom of the detection instrument 5 is meshed with the rotating rod 405. The engagement of gear 402 drives the rotating gear 402 to rotate forward, and then the first conveyor belt 404 and the rotating rod 405 rotate forward, that is, driving the second conveyor belt 406, the driving rod 407, and the gear plate 408 to rotate forward. The bottom end of the lifting shielding plate 4 is provided with a gear plate 401, which is engaged with the gear plate 408. When the gear plate 408 rotates forward, it drives the gear plate 401 to move downward, and the lifting shielding plate 4 moves downward. At this time, the contacts inside the loading box 8 are exposed. When the detection instrument 5 is continuously inserted, the contacts at the tail end of the detection instrument 5 are connected to the contacts inside the loading box 8, and the detection instrument 5 is powered on to realize the detection of the atmospheric environment.

[0039] When the detection instrument 5 is pulled out, the gear bar 501 at the bottom end of the detection instrument 5 engages with the rotating gear 402 in the reverse direction, thereby driving the first conveyor belt 404, the rotating rod 405, the second conveyor belt 406, the driving rod 407 and the gear plate 408 to rotate in the reverse direction. At this time, the lifting shielding plate 4 rises to achieve reset, and the lifting shielding plate 4 shields and protects the contacts inside the loading box 8.

[0040] Example 2:

[0041] The difference from the first embodiment is that, referring to Figure 1-7 This embodiment also has the following further contents: a protective plate 306 is provided at the bottom end of the micro air pump 3, a trigger gear 303 is provided on one side of the micro air pump 3, and a moving part is provided between the trigger gear 303 and the protective plate 306. When the detection instrument 5 is inserted and removed, the gear bar 501 at the top of the detection instrument 5 engages with the trigger gear 30, and the moving part drives the protective plate 306 to move left and right through the forward and reverse rotation of the trigger gear 303. When the protective plate 306 moves toward the trigger gear 303, the air outlet of the micro air pump 3 is exposed. When the moving part moves in the opposite direction, the protective plate 306 is reset to block the air outlet of the micro air pump 3.

[0042] The moving part consists of a trigger gear 303, a connecting gear 304, and a rotating belt 305. The connecting gear 304 is located at the top of the trigger gear 303 and meshes with the trigger gear 303. When the trigger gear 303 rotates forward, it drives the connecting gear 304 to rotate in the opposite direction, thereby driving the rotating belt 305 to move in the opposite direction. The protective plate 306 connected to the rotating belt 305 moves out in the opposite direction, exposing the air outlet of the micro air pump 3.

[0043] In this embodiment, it should be noted that the micro air pump 3 is a micro diaphragm air pump (e.g., volume ≤ 30 cm³, power consumption ≤ 5 W), which has the characteristics of small size, low noise (< 50 dB), and intermittent start and stop.

[0044] The blowing speed of the micro air pump 3 is 10-15m / s (to ensure that dust particles are effectively blown away);

[0045] Micro air pump 3 single purge time: 3-5 seconds (synchronized with the plug-in and unplug action of the detector)

[0046] An intermediate rod is provided in the middle of the connecting gear 304, and a limiting rod 307 is provided on the side of the loading box 8 close to the micro air pump 3. Rotating belts 305 are provided on both sides of the limiting rod 307 and the intermediate rod, and the rotating belt 305 is meshed with the limiting rod 307 and the intermediate rod.

[0047] The gear bar 501 at the top of the detection instrument 5 is set at 1 / 2 of the end of the detection instrument 5 near the contact. When the detection instrument 5 is inserted into the jack, the gear bar 501 engages with the trigger gear 303 located at the top inside the jack, and the trigger gear 303 rotates forward, thereby driving the connecting gear 304 engaged at the top of the trigger gear 303 to rotate reversely, and then driving the rotating belt 305 to rotate reversely. The bottom end of the rotating belt 305 is fixedly connected to one end of the protective plate 306. When the rotating belt 305 rotates reversely, it drives the protective plate 306 to move toward the side of the detection instrument 5. The protective plate 305 leaves the micro air pump 3, exposing the air outlet of the micro air pump 3. The air inlet of the micro air pump 3 is located on one side of the pump body, connected to filter cotton or a hose, and inhales air to the outside from the bottom end of the detection instrument 5.

[0048] The length of the trigger block 303 is 1 / 4 of the length of the top of the detection instrument 5. When the gear bar 501 near the contact is connected to the trigger gear 304, the trigger block 303 enters the socket, and the trigger block 303 presses inward against the air pump switch 301. The power supply of the micro air pump 3 is connected, and the air outlet of the micro air pump 3 is aimed at the grid plate 7 through the nozzle for blowing.

[0049] Since the length of the trigger block 303 is 1 / 4 of the length of the top end of the detection instrument 5, as the detection instrument 5 is inserted to the end, the trigger block 303 leaves the air pump switch 301, and the micro air pump 3 stops blowing; when the detection instrument 5 is pulled out, the trigger block 303 again presses against the air pump switch 301 of the micro air pump 3, and the micro air pump 3 blows the contact position of the detection instrument 5, thereby automatically blowing away the dust on the contact surface every time the detection instrument 5 is plugged in or out.

[0050] Example 3:

[0051] Reference Figure 1 as well as Figure 8 Compared with the first and second embodiments, in this embodiment: the cross-section of the chassis 103 is in the shape of an inverted truncated cone, and a multi-fixed base 1 is provided at the bottom end of the chassis 103. A card slot 105 is provided inside the multi-fixed base 1 near the chassis 103, and a card rod 106 is provided on the outside of the chassis 103 at a position corresponding to the card slot 105. The card slot 105 and the card rod 106 are connected in a mortise and tenon-like manner.

[0052] like Figure 2-3 As shown, the length of the gear bar 801 at the top of the detection instrument 8 is 1 / 2 of the length of the top of the detection instrument 5, the length of the gear bar 501 at the bottom of the detection instrument 5 is consistent with the length of the bottom of the detection instrument 5, and a trigger block 302 is provided on the side of the top of the detection instrument 5 away from the gear bar 501. An air pump switch 301 is provided inside the loading box 8 near the outside, and the length of the trigger block 302 is 1 / 4 of the length of the top of the detection instrument 5.

[0053] like Figure 2As shown, a grid plate 7 is provided at the bottom end of the loading box 8, and the discharge port of the micro air pump 3 is facing the position of the grid plate 7. A rotating component is provided on the chassis 103, and the rotating component is composed of a wind direction monitor and a drive motor 104. The rotating component drives the chassis 103 to rotate through the internal drive motor 104, so that the detection port of the detection instrument 5 is facing the wind direction to detect the atmospheric environment. A collection drawer 601 is provided at the bottom end of the loading box 8, and a collection funnel 6 is provided at the top of the collection drawer 601 near the grid plate.

[0054] In this embodiment, it should be noted that a wind turbine 2 is provided at the top of the loading box 8. The wind turbine 2 is connected to the lithium battery inside the loading box. It uses natural wind to drive the fan blades to rotate while generating electricity to charge the lithium battery of the equipment, thereby achieving low power consumption operation and improving environmental protection performance.

[0055] A hydraulic lifting rod is provided at the top of the chassis 103 , and the loading box 8 is arranged at the top of the hydraulic lifting rod.

[0056] The card slot 105 and the card rod 106 are connected in a mortise and tenon-like manner to realize the rotational engagement of the multi-fixed base 1 and the chassis 103. A wind direction monitor is provided on the loading box 8. The wind direction monitor and the drive motor 104 are telecommunication-connected to a PLC controller of model: "Siemens S7-1200". The wind direction monitor provides real-time feedback of wind direction data and sends an electrical signal to the drive motor 104 through the PLC controller. The drive motor 104 starts and drives the chassis 103, the hydraulic lifting rod and the loading box 8 to rotate 360° freely, so that the detection port of the detection instrument 5 installed on the loading box 8 makes the inlet inspection tube always face the incoming wind direction to detect the atmospheric environment.

[0057] The loading box 8 is made of an IP65-grade waterproof and dustproof shell. The collecting funnel 6 is arranged at the bottom end of the grid plate 7, and the collecting funnel 6 is arranged in the middle of the two second conveyor belts 406. The top of the collecting funnel 6 is fixedly connected to the bottom of the grid plate 7. The mesh of the grid plate 7 is relatively large. When the micro air pump 3 is started, the internal sand and dust are blown toward the position of the grid plate 7, so that the dust can pass through the mesh of the grid plate 7 and flow down through the collecting funnel 6 into the collecting drawer 601 for collection. The collecting drawer 601 can be pulled out through the external handle of the collecting drawer 601, and the dust collected inside can be cleaned uniformly.

[0058] A detachable conical plug rod 101 is provided at the bottom end of the multi-fixed base 1. The conical plug rod 101 is installed and disassembled by screwing in and out of the thread. On soft ground, the conical plug rod 101 can be inserted into the soil to assist in fixing the entire device. Expansion bolt holes 102 are provided around the multi-fixed base 1. When installing on hardened ground, the expansion screws can be inserted into the expansion bolt holes 102 to fix the entire device; the bottom end of the multi-fixed base 1 is provided with multiple magnetic interfaces, which can quickly fix the entire device during vehicle transportation.

[0059] A 5G / 4G wireless transmission module and a GPS positioning module are installed inside the loading box 8, so that the data of the detection instrument 5 can be uploaded to the cloud platform in real time and the geographic location information is marked. In addition, a local storage chip is added to support temporary storage of data when the network is disconnected, and automatic resumption of transmission after the network is restored, so as to realize remote monitoring and data traceability.
