Description

Technical Field

[0001] The present application belongs to the technical field of unmanned aerial vehicles, and in particular, relates to a gas collection device for unmanned aerial vehicles and a collection method thereof. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous", such as environmental monitoring. There are many reasons for air pollution, such as: waste gas emissions in industrial production processes, waste gas emissions in garbage treatment plants around cities. The polluted gases generated in the above examples seriously exceed the standard. Some of these gases, such as carbon dioxide and methane, have a greenhouse effect, hydrogen sulfide and ammonia will produce pungent odors, and sulfur dioxide, nitrogen oxides, dust, etc. will affect the air quality of the city. Therefore, it is necessary to collect and detect polluted gases in multiple locations of factories and garbage treatment plants. Most of the existing detection equipment is mobile robots or drones.

[0004] The patent with publication number CN113532962B discloses a polluted gas collection device based on a drone, which relates to the field of gas collection technology. The device uses the fountain flow formed by the collision of the downwash airflow of the main drone and the auxiliary drone to quickly and accurately collect the polluted gas, reducing the influence of the downwash airflow on the gas spatial distribution and improving the reliability of the sample.

[0005] The above patent completes the gas collection work by using an air pump, a rotating platform, multiple air storage boxes, an electric push rod and an intake pipe. Although it can achieve the work, it is difficult to control the axial extension and contraction of the intake pipe, and it is easy to deviate and cause jamming, so it needs to be improved. Summary of the invention

[0006] The purpose of this application is to provide a gas collection device and a collection method for drones, which can solve the above problems.

[0007] The purpose of the present application is to provide a gas collection device for a drone, comprising a main drone, a secondary drone, and a gas collection device arranged on the main drone, wherein the gas collection device comprises:

[0008] A mounting platform, which is set on the main UAV;

[0009] The telescopic air tube comprises an outer tube body and a plurality of inner tube bodies, and the telescopic air tube is connected to an air pump and an air storage box;

[0010] The driving mechanism is arranged on the mounting platform and is used to drive the telescopic air pipe to operate, and the driving mechanism includes:

[0011] The telescopic mechanism is used to drive the telescopic air pipe to move in a telescopic manner;

[0012] A rotating mechanism, used for driving the telescopic air tube to rotate;

[0013] Wherein, the telescopic mechanism is arranged on the rotating mechanism, and the rotating mechanism drives the telescopic mechanism and the telescopic air pipe to rotate together.

[0014] By using the above-mentioned gas collection device for drones, adjusting and calibrating the collection position through the cooperation of the main drone and the auxiliary drone, the influence of the downwash airflow on the gas distribution can be effectively reduced, and the accuracy of gas sample collection can be improved. It can also be applicable to multiple scenarios. The gas collection work can be completed with the coordinated use of the telescopic air pipe, the driving mechanism, the telescopic mechanism and the rotating mechanism. Among them, by setting the telescopic mechanism, the extension length of the telescopic air pipe can be adjusted, and the stability of the telescopic air pipe extension can be ensured, which can effectively prevent the telescopic air pipe from getting stuck during extension and retraction.

[0015] Furthermore, the rotating mechanism includes a rotating table and a servo motor for driving the rotating table to rotate. One end of the telescopic air pipe passes through the rotating table and is connected to the air storage box. Driven by the servo motor, the rotating table with multiple telescopic air pipes rotates around the center of the mounting table.

[0016] The position of the telescopic air tube can be adjusted in real time through the rotating mechanism so that it can be quickly aligned with the secondary UAV. The rotating table can be rotated under the drive of the servo motor, and the rotating table drives the telescopic air tube to rotate. The rotation work needs to be done after the UAV is hovering. At the same time, the camera installed on the UAV can be used to determine whether the telescopic air tube is aligned with the secondary UAV. If not, the rotating mechanism can be controlled to operate until it is aligned.

[0017] Further: the telescopic mechanism comprises:

[0018] A first fixing seat is disposed on the rotating platform and connected to one end of the outer tube body;

[0019] A second fixing seat is arranged on the mounting platform and connected to the other end of the outer tube body, and an arc-shaped guide rail adapted to the second fixing seat is arranged on the mounting platform;

[0020] A sealing head is arranged on the inner rod body;

[0021] The telescopic structure includes a screw rod, a driving rod disposed on a second fixed seat, and a connecting head rotatably connected to one end of the driving rod, the connecting head is threadedly connected to the screw rod, and one end of the driving rod passes through the second fixed seat and is connected to the sealing head;

[0022] A driver is disposed on the rotating table, and the driver is connected via a coupling screw;

[0023] Wherein, a sliding hole for the driving rod to pass through is arranged on the second fixing seat, and a stabilizing structure is arranged between the sliding hole and the driving rod.

[0024] In the present application, the driver is a motor, and the motor is operated by external power supply. The power supply device here can be a battery. When the telescopic mechanism is in operation, the driver starts to drive the screw to rotate through the coupling. Under the cooperation of the screw and the connector, the connector rotates and causes the driving rod to move axially. When the driving rod moves, it drives the connector to move, and the connector drives the inner tube body to move, thereby completing the telescopic movement of the inner sleeve and the outer sleeve. Among them, the first fixed seat and the second fixed seat are respectively installed at the two ends of the outer tube body, which play the role of guiding and limiting, preventing the driving rod from offset when moving, and also play the role of fixing the outer tube body. The setting of the arc guide rail can enable the second fixed seat to move along the arc guide rail to prevent the second fixed seat from affecting the rotation of the rotating mechanism. At the same time, during the movement of the driving rod, it will contact the sliding hole on the second fixed seat, so that the axial movement of the driving rod is more stable. In addition, when adjusting the telescopic, the user can remotely control the driver to adjust the telescopic length of the telescopic air pipe, and the adjusted picture is fed back through the camera.

[0025] Furthermore, both ends of the sealing head are provided with air inlets connected to the inner tube body, and a filter screen is provided at the air inlet, and the filter screen and the air inlet are detachably connected.

[0026] By arranging two air inlets on the sealing head, the air intake efficiency can be expanded, thereby improving the gas collection efficiency. Opening multiple air inlets can avoid the problem of a single air inlet being unable to collect gas due to blockage. Installing a filter on the air inlet can block large particles of impurities and play a protective role. Configuring the filter and the air inlet as a detachable structure can facilitate the installation and disassembly of the filter, and facilitate the replacement and cleaning of the filter.

[0027] Furthermore, the stable structure comprises:

[0028] The shifting blocks are arranged on both sides of the outer wall of the driving rod;

[0029] Main slide grooves are arranged on both sides of the sliding hole and are adapted to the shifting block;

[0030] A stabilizing assembly, disposed in the main slide and cooperating with the shifting block;

[0031] When the telescopic air pipe is extended or retracted, the driving rod contacts the stabilizing component through the shifting block and drives the stabilizing component to move.

[0032] The stabilizing structure includes a shift block, a main slide and a stabilizing component. The shift block is arranged on both sides of the driving rod, and the main slide is opened on both sides of the sliding hole for the shift block to pass through, while the stabilizing component is located in the main slide. When the shift block passes through, the stabilizing component contacts and interacts with the stabilizing component. When the telescopic air tube is extended or retracted, the driving rod contacts the stabilizing component through the shift block and drives the stabilizing component to move, thereby making the extension and retraction process of the telescopic air tube more stable.

[0033] Furthermore, the stabilizing component includes:

[0034] Guide grooves are arranged on both sides of the main slide;

[0035] A guide slider is disposed in the guide groove and can slide along the guide groove;

[0036] A first shifting rod is arranged at one end of the guide slider and is hinged to the guide slider, the first shifting rod is adapted to the guide groove and is in contact with the shifting block;

[0037] A second lever is arranged at the other end of the guide slider and is hinged to the guide slider, the second lever is adapted to the guide groove and is in contact with the lever block;

[0038] The first damping rod, whose telescopic end is connected to the guide slider

[0039] A second damping rod, a telescopic end of which is connected to the guide slider;

[0040] When the driving rod moves, the first shifting rod and the second shifting rod are driven to move through the shifting block.

[0041] There are two situations for the telescopic air tube, one is when the telescopic air tube is extended, and the other is when the telescopic air tube is retracted. When the telescopic air tube is extended, the driving rod gradually moves away from the driving rod under the action of the driver and drives the inner tube body to gradually extend. During the extension process, the lever contacts the first lever and drives the first lever to gradually move from one end of the guide slot to the other end. During this process, the telescopic end of the first damping rod gradually retracts, and the telescopic end of the second damping rod is gradually extended, so that the movement of the driving rod is more rapid and stable, and the extension of the inner tube body is more stable.

[0042] When the telescopic air tube retracts, the driving rod gradually approaches the driver under the action of the driver and drives the inner tube body to gradually retract. During the retraction process, the quick lever contacts the second lever and drives the second lever to gradually move from the other end to the one end of the guide slot. During this process, the telescopic end of the second damping rod gradually retracts, and the telescopic end of the first damping rod is gradually stretched, so that the movement of the driving rod is more rapid and stable, and the retraction of the inner tube body is more stable.

[0043] Therefore, whether it is extending or retracting, it will be affected by the stable structure, which can effectively avoid the telescopic air tube from getting stuck or stuck during extension and retraction, making the extension and retraction more rapid and stable, and preventing deviation. In addition, by setting a guide slider, it can fix the first lever and the second lever, and can also play an overall limiting guiding role to prevent it from detaching from the guide slot during movement.

[0044] Furthermore, the stabilizing component further comprises:

[0045] A first arc-shaped groove is provided at one end of the guide groove;

[0046] A second arc groove is provided at the other end of the guide groove;

[0047] A first spring, one end of which is connected to the first lever, and the other end of which is connected to the main slide groove;

[0048] A second spring, one end of which is connected to the second lever, and the other end of which is connected to the main slide groove;

[0049] The first lever is matched with the first arc groove and can slide along the first arc, and the second lever is matched with the second arc groove and can slide along the second arc.

[0050] In order to avoid being blocked by the first lever and the second lever during the movement of the quick-acting lever, the present application provides a first arc groove and a second arc groove. When the telescopic air pipe is extended, the shift block contacts the first lever and drives the first lever to move. When the first lever moves to the connection between the guide slide groove and the first arc groove, the angle between the first lever and the guide slide block changes, and the first lever enters the first arc groove. At this time, the first lever cannot block the movement of the quick-acting lever, and the driving rod can move. In the process of the first lever entering the first arc groove, the second lever moves from the second arc groove to the guide groove. In this process, the first spring is stretched and the second spring retracts, which further plays a damping and buffering effect, making the movement of the driving rod more rapid and stable.

[0051] When the telescopic air pipe retracts, the shift block contacts the second shift rod and drives the second shift rod to move. When the second shift rod moves to the connection between the guide slide groove and the second arc groove, the angle between the second shift rod and the guide slide block changes, and the second shift rod enters the second arc groove. At this time, the second shift rod cannot block the movement of the shift rod, and the driving rod can continue to move. In the process of the second shift rod entering the second arc groove, the first shift rod moves from the first arc groove to the guide groove. In this process, the second spring is stretched and the first spring retracts, which further plays a damping and buffering effect, making the movement of the driving rod more rapid and stable. Through the cooperation of the two, the telescopic process can be subject to the damping and buffering effect. Moreover, since the first arc groove and the other arc grooves are arc structures, they have a certain fixing effect, which can fix the positions of the first shift rod and the second shift rod to prevent resetting after movement.

[0052] Furthermore, the present invention also discloses a gas collection method for a drone gas collection device, comprising the following steps:

[0053] S1. Control the main UAV and the auxiliary UAV to fly to the collection position, and adjust the hovering position according to the collection position;

[0054] S2. When the main and auxiliary drones hover stably, the servo motor controls the rotating table to rotate so that the telescopic air tube points to the auxiliary drone, and then the telescopic mechanism operates to extend the telescopic air tube and adjust the extension distance;

[0055] S3, turning on the air pump and collecting gas, the gas enters the filter, the air inlet, the inner tube body and the outer tube body and is stored in the gas storage box;

[0056] S4, gas collection contact, the telescopic mechanism operates to retract the telescopic air pipe, and the servo motor controls the rotary table to reset;

[0057] S5. Control the main and auxiliary drones to return.

[0058] The beneficial effects of this application are:

[0059] 1. The gas collection work can be completed by the coordinated use of the telescopic air pipe, the driving mechanism, the telescopic mechanism and the rotating mechanism. By setting the telescopic mechanism, the extension length of the telescopic air pipe can be adjusted, and the stability of the telescopic air pipe can be ensured, which can effectively prevent the telescopic air pipe from getting stuck during extension;

[0060] 2. During the extension of the telescopic air tube, the telescopic end of the first damping rod gradually retracts, and the telescopic end of the second damping rod is gradually stretched, so that the movement of the driving rod is more rapid and stable, and the extension of the inner tube body is more stable; during the retraction of the telescopic air tube, the lever contacts the second lever and drives the second lever to gradually move from the other end to the one end of the guide slot. During this process, the telescopic end of the second damping rod gradually retracts, and the telescopic end of the first damping rod is gradually stretched, so that the movement of the driving rod is more rapid and stable, and the retraction of the inner tube body is more stable;

[0061] 3. When the telescopic air pipe retracts, the shift block contacts the second shift rod and drives the second shift rod to move. When the second shift rod moves to the connection between the guide slide groove and the second arc groove, the angle between the second shift rod and the guide slide block changes, and the second shift rod enters the second arc groove. At this time, the second shift rod cannot block the movement of the shift rod, and the driving rod can continue to move. In the process of the second shift rod entering the second arc groove, the first shift rod moves from the first arc groove to the guide groove. In this process, the second spring is stretched and the first spring retracts, which further plays a damping and buffering effect, making the movement of the driving rod more rapid and stable. Through the cooperation of the two, the telescopic process can be subject to the damping and buffering effect. Moreover, since the first arc groove and the other arc grooves are arc structures, they have a certain fixing effect, and the positions of the first shift rod and the second shift rod can be fixed to prevent resetting after movement.

[0082] like Figure 1 and Figure 4 As shown, the rotating mechanism 400 includes a rotating table 410 and a servo motor 420 for driving the rotating table 410 to rotate. One end of the telescopic air tube 300 passes through the rotating table 410 and is connected to the air storage box 330. Driven by the servo motor 420, the rotating table 410 with the multiple telescopic air tubes 300 rotates around the center of the mounting table 200.

[0083] In the embodiment of the present application, the position of the telescopic air tube 300 can be adjusted in real time through the rotating mechanism 400 so that it can be quickly aligned with the sub-UAV 110. The rotating table 410 can be rotated under the drive of the servo motor 420, and the rotating table 410 drives the telescopic air tube 300 to rotate. The rotation work needs to be performed after the UAV is hovering. At the same time, the camera installed on the UAV is used to determine whether the telescopic air tube 300 is aligned with the sub-UAV 110. If not, the rotating mechanism 400 can be controlled to operate until it is aligned.

[0084] Embodiment 3:

[0085] An embodiment of the present application provides a gas collection device for a drone. In addition to the above-mentioned technical features, the gas collection device for a drone in the embodiment of the present application also includes the following technical features.

[0086] As 1 and Figure 4 As shown, the telescopic mechanism 500 includes:

[0087] A first fixing seat 510 is disposed on the rotating platform 410 and connected to one end of the outer tube 310;

[0088] A second fixing seat 520 is disposed on the mounting platform 200 and connected to the other end of the outer tube body 310 . The mounting platform 200 is provided with an arc-shaped guide rail 521 adapted to the second fixing seat 520 .

[0089] The sealing head 530 is arranged on the inner rod body;

[0090] The telescopic structure 540 includes a screw rod 541, a driving rod 542 disposed on the second fixing seat 520, and a connecting head 543 rotatably connected to one end of the driving rod 542. The connecting head 543 is threadedly connected to the screw rod 541. One end of the driving rod 542 passes through the second fixing seat 520 and is connected to the sealing head 530.

[0091] A driver 550 is disposed on the rotating platform 410 and is connected via a coupling screw 541;

[0093] In the embodiment of the present application, in the present application, the driver 550 is a motor, and the motor is operated by external power supply. The power supply device here can be a battery. When the telescopic mechanism 500 is in operation, the driver 550 starts to drive the screw 541 to rotate through the coupling. Under the cooperation of the screw 541 and the connecting head 543, the connecting head 543 rotates and causes the driving rod 542 to move axially. When the driving rod 542 moves, it drives the connecting head 543 to move, and the connecting head 543 drives the inner tube body 320 to move, thereby completing the telescopic movement of the inner sleeve and the outer sleeve. Among them, the first fixed seat 510 and the second fixed seat 520 are respectively installed at the two ends of the outer tube body 310, which play a guiding and limiting role to prevent the driving rod 542 from being offset when moving, and also play a role in fixing the outer tube body 310. The setting of the arc guide rail 521 can enable the second fixed seat 520 to move along the arc guide rail 521 to prevent the second fixed seat 520 from affecting the rotation of the rotating mechanism 400. At the same time, during the movement of the driving rod 542, it will contact the sliding hole 560 on the second fixed seat 520, so that the axial movement of the driving rod 542 is more stable. In addition, when adjusting the telescopic length, the user can remotely control the driver 550 to adjust the telescopic length of the telescopic air tube 300, and the adjusted picture is fed back through the camera.

[0095] By providing two air inlets 531 on the sealing head 530, the air intake efficiency can be expanded, thereby improving the gas collection efficiency, and the provision of multiple air inlets 531 can avoid the problem of a single air inlet 531 being unable to collect gas due to blockage. Installing a filter 532 on the air inlet 531 can block large particles of impurities and play a protective role. Configuring the filter 532 and the air inlet 531 as a detachable structure can facilitate the installation and disassembly of the filter 532, and facilitate the replacement and cleaning of the filter 532.

[0104] Embodiment 5:

[0105] An embodiment of the present application provides a gas collection device for a drone. In addition to the above-mentioned technical features, the gas collection device for a drone in the embodiment of the present application also includes the following technical features.

[0106] like Figure 5 As shown, the stabilizing assembly 700 includes:

[0107] The guide grooves 710 are arranged on both sides of the main slide groove 620;

[0108] A guide slider 720 is disposed in the guide groove 710 and can slide along the guide groove 710;

[0114] In the embodiment of the present application, the telescopic air tube 300 is divided into two situations, one is when the telescopic air tube 300 is extended, and the other is when the telescopic air tube 300 is retracted. When the telescopic air tube 300 is extended, under the action of the driver 550, the driving rod 542 gradually moves away from the driver 550 and drives the inner tube body 320 to gradually extend. During the extension process, the first lever 730 contacts and drives the first lever 730 to gradually move from one end of the guide slot to the other end. During this process, the telescopic end of the first damping rod 750 is gradually retracted, and the telescopic end of the second damping rod 760 is gradually extended, so that the movement of the driving rod 542 is more rapid and stable, and the extension of the inner tube body 320 is more stable.

[0115] When the telescopic air tube 300 retracts, the driving rod 542 gradually approaches the driving rod 550 under the action of the driver 550 and drives the inner tube body 320 to gradually retract. During the retraction process, the lever contacts the second lever 740 and drives the second lever 740 to gradually move from the other end of the guide slot to one end. During this process, the telescopic end of the second damping rod 760 gradually retracts, and the telescopic end of the first damping rod 750 is gradually stretched, so that the movement of the driving rod 542 is more rapid and stable, and the retraction of the inner tube body 320 is more stable.

[0116] Therefore, whether it is extending or retracting, it will be affected by the stabilizing structure 600, which can effectively prevent the telescopic air tube 300 from getting stuck or jammed during extension and retraction, making the extension and retraction more rapid and stable, and preventing deviation. In addition, by setting the guide slider 720, it can fix the first lever 730 and the second lever 740, and can also play an overall limiting guiding role to prevent it from detaching from the guide slot during movement.

[0117] Furthermore, the stabilizing assembly 700 further includes:

[0118] A first arc groove 770 is provided at one end of the guide groove 710;

[0119] A second arc groove 780 is provided at the other end of the guide groove 710;

[0120] A first spring 790, one end of which is connected to the first lever 730, and the other end of which is connected to the main slide groove 620;

[0121] A second spring 791, one end of which is connected to the second lever 740, and the other end of which is connected to the main slide groove 620;

[0122] The first lever 730 is matched with the first arc groove 770 and can slide along the first arc, and the second lever 740 is matched with the second arc groove 780 and can slide along the second arc.

[0123] When the first lever 730 is moved to the connecting portion of the guide slot and the first arc groove 770, the angle between the first lever 730 and the guide slider 720 changes, and the first lever 730 enters the first arc groove 770. At this time, the first lever 730 cannot block the movement of the lever, and the driving rod 542 can move. In the process of the first lever 730 entering the first arc groove 770, the second lever 740 moves from the second arc groove 780 to the guide slot 710. In this process, the first spring 790 is stretched and the second spring 791 is retracted, which further plays a damping and buffering effect, making the movement of the driving rod 542 more rapid and stable.

[0124] When the telescopic air pipe 300 is retracted, the shift block 610 contacts the second shift rod 740 and drives the second shift rod 740 to move. When the second shift rod 740 moves to the connection between the guide slide groove and the second arc groove 780, the angle between the second shift rod 740 and the guide slider 720 changes, and the second shift rod 740 enters the second arc groove 780. At this time, the second shift rod 740 cannot block the movement of the shift rod, and the driving rod 542 can continue to move. In the process of the second shift rod 740 entering the second arc groove 780, the second shift rod 740 is A lever 730 moves from the first arc groove 770 to the guide groove 710. During this process, the second spring 791 is stretched and the first spring 790 retracts, further playing a damping and buffering effect, making the movement of the driving rod 542 more rapid and stable. Through the cooperation of the two, the telescopic process can be affected by the damping and buffering effect. Moreover, since the first arc groove 770 and other arc grooves are arc structures, they have a certain fixing effect, which can fix the positions of the first lever 730 and the second lever 740 to prevent resetting after movement.
