DETAILED DESCRIPTION

[0018] The following will be described in detail with reference to the accompanying drawings Figures 1-5 The present application is further described in detail.

[0019] The embodiment of the present application discloses an air quality detection device. Referring to Figure 1 An air quality detection device comprises a mounting column 1, a detector body 2 and an unmanned aerial vehicle body 3.

[0020] The mounting column 1 is fixedly installed on the ground through bolts. The detector body 2 is fixedly connected to the bottom of the unmanned aerial vehicle body 3, and a mounting assembly 4 is arranged between the detector body 2 and the mounting column 1, and the mounting assembly 4 is used for realizing detachable connection of the detector body 2 and the mounting column 1.

[0021] Referring to Figure 2 and Figure 3 , the mounting assembly 4 comprises a mounting seat 41, a connecting seat 42, a clamping part 43 and a magnetic control part 44.

[0022] Referring to Figure 1 , Figure 3 and Figure 4 , the mounting seat 41 is fixedly connected to the top end of the mounting column 1, the connecting seat 42 is fixedly connected to the bottom end of the detector body 2, the connecting seat 42 is fixedly connected with a clamping joint 421, the clamping part 43 is arranged on the mounting seat 41, and the clamping part 43 is provided with a clamping notch, and the clamping joint 421 can be clamped and rotated to the clamping part 43 through the clamping notch, so as to realize connection of the mounting seat 41 and the connecting seat 42.

[0023] Referring toFigure 2 and Figure 4 The magnetic control part 44 is arranged between the mounting base 41 and the connecting base 42, and is used to control the opening and closing of the clamping gap based on the starting condition of the UAV body 3; when the UAV body 3 is in the starting state, the magnetic control part 44 opens the clamping gap to facilitate the clamping head 421 to enter or exit the clamping gap, and when the UAV body 3 is in the shutdown state, the magnetic control part 44 closes the clamping gap to limit the clamping head 421 from disengaging from the clamping part 43; in the case that the clamping gap is opened, the clamping head 421 can be positively rotated and clamped to the clamping part 43 under the drive of the UAV body 3, and the clamping head 421 can be reversely rotated and disengaged from the clamping part 43 under the drive of the UAV body 3.

[0024] In the normal state, the UAV body 3 and the detector body 2 are connected to the mounting base 41 through the connecting base 42, and the detector body 2 can perform point air detection; when it is necessary to expand the detection range, the UAV body 3 is started, the magnetic control part 44 can open the clamping gap, and the started UAV body 3 can drive the clamping head 421 to reversely rotate to make the clamping head 421 exit the clamping part 43, so that the connection between the mounting base 41 and the connecting base 42 can be released, and the UAV body 3 can carry the detector body 2 to fly to perform regional air detection in a cruising manner, thereby expanding the detection range of the air quality detection device.

[0025] After the cruising detection is completed, the UAV body 3 carries the detector body 2 to fly back to the mounting base 41, and after the connecting base 42 approaches the mounting base 41, the UAV body 3 drives the clamping head 421 to positively rotate to make the clamping head 421 clamped to the clamping part 43 from the clamping gap, thereby realizing the connection between the connecting base 42 and the mounting base 41, stopping the UAV body 3, and closing the clamping gap by the magnetic control part 44 to make it difficult for the clamping head 421 to disengage from the clamping part 43, so that the UAV body 3 and the detector body 2 are not easy to disengage from the mounting column 1, and the detector body 2 can perform point detection.

[0026] Under the cooperation of the magnetic control part 44 and the UAV body 3, the connection and disconnection between the connecting base 42 and the mounting base 41 can be automatically realized without manual on-site operation, thereby improving the overall automation degree of the detection device, reducing the labor intensity, and enhancing the convenience of using the detection device.

[0027] Fixed-point detection data can reflect the long-term air quality around the fixed location of the detector body 2, while cruise detection data can periodically reflect the air quality in the area surrounding the detector body 2. Combining fixed-point detection data and cruise detection data can more accurately reflect the outdoor air quality, thereby expanding the detection range of the air quality detection device and improving the reliability of the detection results based on the expanded air detection data.

[0028] Specifically, refer to Figure 4 The snap-fit ​​part 43 includes a first snap ring 431, a second snap ring 432, and a closing plate 433.

[0029] Reference Figure 3 and Figure 4 The first retaining ring 431 and the second retaining ring 432 are both fixedly connected to the wall of the mounting hole 411 opened in the middle of the mounting base 41. The first retaining ring 431 is located above the second retaining ring 432. The first retaining ring 431 has a snap-fit ​​hole 4311, which forms the snap-fit ​​notch of the snap-fit ​​part 43. The closing plate 433 is hinged to the snap-fit ​​hole 4311 through the hinge shaft 434. The closing plate 433 is used to open or close the snap-fit ​​hole 4311. The wall surface of the snap-fit ​​hole 4311 near the wall of the mounting hole 411 is flush with the wall of the mounting hole 411.

[0030] The magnetic control unit 44 is used to control the sealing plate 433 to swing forward and abut against the second retaining ring 432 to open the retaining hole 4311. The magnetic control unit 44 is also used to control the sealing plate 433 to swing in the opposite direction to close the retaining hole 4311. The retaining head 421 is provided with a release ramp 422 that can slide onto the sealing plate 433 to assist the retaining head 421 in releasing itself between the first retaining ring 431 and the second retaining ring 432.

[0031] When it is necessary to connect the mounting base 41 and the connecting base 42, the magnetic control unit 44 controls the sealing plate 433 to swing forward and abut against the second retaining ring 432. During the forward rotation, the retaining connector 421 can rotate to the retaining hole 4311. The retaining connector 421 can slide along the sealing plate 433 into the space between the first retaining ring 431 and the second retaining ring 432, and can rotate continuously between the first retaining ring 431 and the second retaining ring 432. After the retaining connector 421 slides into the space between the first retaining ring 431 and the second retaining ring 432, the drone body 3 stops. The magnetic control unit 44 controls the sealing plate 433 to swing and close the retaining hole 4311, making it difficult for the retaining connector 421 to come out of the retaining hole 4311 between the first retaining ring 431 and the second retaining ring 432.

[0032] Under the unidirectional guiding action of the sealing plate 433, the forward-rotating snap-fit ​​connector 421 is difficult to disengage between the first snap ring 431 and the second snap ring 432, allowing the detection direction of the detector body 2 to be adjusted under the drive of the drone body 3. When it is necessary to disconnect the mounting base 41 from the connecting base 42, the magnetic control unit 44 controls the sealing plate 433 to swing forward and abut against the second snap ring 432. The drone body 3 drives the snap-fit ​​connector 421 to rotate in the opposite direction. The reverse-rotating snap-fit ​​connector 421 can slide up onto the sealing plate 433 through the disengagement ramp 422. Under the guiding action of the sealing plate 433, the snap-fit ​​connector 421 can disengage between the first snap ring 431 and the second snap ring 432, thereby allowing the snap-fit ​​connector 421 to disengage between the first snap ring 431 and the second snap ring 432 under the drive of the drone body 3.

[0033] Reference Figure 3 In order to facilitate the insertion of the snap-fit ​​connector 421 into the snap-fit ​​hole 4311, a guide plate 435 is fixedly connected to the side of the first snap-fit ​​ring 431 away from the second snap-fit ​​ring 432. The guide plate 435 is located close to the snap-fit ​​hole 4311 and is curved in an arc shape. The guide plate 435 is used to guide the snap-fit ​​connector 421 into the snap-fit ​​hole 4311 when the snap-fit ​​connector 421 rotates in the forward direction.

[0034] The arc-shaped guide plate 435 can guide and restrict the rotating snap-fit ​​connector 421, so that the snap-fit ​​connector 421 can only slide along the closed plate 433. This makes it less likely for the snap-fit ​​connector 421 to slip past the snap-fit ​​hole 4311 when it rotates to the snap-fit ​​hole 4311, thus making it easier for the snap-fit ​​connector 421 to slide into the snap-fit ​​hole 4311.

[0035] Specifically, refer to Figure 3 The magnetic control unit 44 includes an electromagnetic ring 441, a permanent magnet block 442, a control rack 443, and a control gear 444.

[0036] Reference Figure 3 and Figure 4 The electromagnetic ring 441 is fixedly embedded in the connecting seat 42, and the permanent magnet 442 is slidably disposed in the control groove 412 opened on the mounting seat 41, with the sliding direction being vertical. When the drone body 3 is powered on, the polarities of the electromagnetic ring 441 and the permanent magnet 442 on the side closest to each other are the same; when the drone body 3 is stopped, the polarities of the electromagnetic ring 441 and the permanent magnet 442 on the side closest to each other are opposite.

[0037] Both the control rack 443 and the control gear 444 are set in the transmission groove 413 opened on the mounting base 41. The transmission groove 413 is connected to the control slide 412. The control rack 443 meshes with the control gear 444. The control rack 443 is fixedly connected to the connecting rod 4431. The connecting rod 4431 is fixedly connected to the permanent magnet block 442. The control gear 444 is fixedly connected to the hinge shaft 434.

[0038] When the UAV body 3 is activated, the electromagnetic ring 441 and the permanent magnet block 442 are in a state of mutual repulsion. Under the action of magnetic thrust, the permanent magnet block 442 can slide down to the bottom of the control chute 412. The permanent magnet block 442 drives the control rack 443 to move through the connecting rod 4431. The control rack 443 drives the control gear 444 to rotate. The control gear 444 can drive the hinge shaft 434 to rotate. The hinge shaft 434 can drive the closing plate 433 to swing, so that the snap-fit ​​hole 4311 opens. When the UAV body 3 is stopped, the electromagnetic ring 441 and the permanent magnet block 442 can be in a state of mutual attraction. The permanent magnet block 442 can slide up to the slot position of the control slide 412. The permanent magnet block 442 can drive the sealing plate 433 to close the snap-fit ​​hole 4311 through the control rack 443 and the control gear 444. The magnetic attraction between the electromagnetic ring 441 and the permanent magnet block 442 can also apply a fixing force to the connecting seat 42 and the mounting seat 41, so that the detector body 2 is not easy to rotate freely under normal conditions.

[0039] Reference Figure 4 To facilitate the docking and installation of the mounting base 41 and the connecting base 42, the mounting surfaces of the mounting base 41 and the connecting base 42 that are close to each other are conical. By installing the connecting base 42 and the mounting base 41 through the conical mounting surfaces, the connecting base 42 is easy to position relative to the mounting base 41, which facilitates the insertion of the snap-fit ​​connector 421 into the mounting hole 411, thereby facilitating the docking of the connecting base 42 and the mounting base 41 and improving the connection efficiency between the connecting base 42 and the mounting base 41.

[0040] Reference Figure 2 and Figure 3 In order to reduce the frictional resistance of the drive connector 42 rotating on the UAV body 3, the number of the snap connector 421, snap hole 4311, permanent magnet 442, control rack 443 and control gear 444 are the same in pairs, and multiple permanent magnets 442 are evenly arranged around the axis of the mounting base 41.

[0041] The uniformly arranged permanent magnet blocks 442 can form a stable and central magnetic thrust on the electromagnetic ring 441. On the one hand, it helps the connector 421 to be inserted into the mounting hole 411 in a centered position. On the other hand, it helps to reduce the frictional resistance between the connector 42 and the mounting base 41 or between the connector 421 and the first retaining ring 431, making it easier for the UAV body 3 to drive the connector 421 to rotate.

[0042] Reference Figure 4 In order to enable the connector 42 to quickly locate and approach the mounting base 41 after the flight, a camera 5 is connected to the center of the bottom surface of the connector 42. When the connector 42 is installed on the mounting base 41, the camera 5 can be located inside the mounting hole 411. The camera 5 can capture video images of the area below the connector 42. The video images help the user to quickly locate the mounting base 41, and the user can determine the relative position of the connector 42 and the mounting base 41 based on the video images, thus speeding up the connection efficiency between the connector 42 and the mounting base 41.

[0043] Reference Figure 1 and Figure 2 In order to protect the propellers of the drone body 3 in severe weather, a protective component 6 is provided on the connecting seat 42. The number of protective components 6 is the same as the number of propellers on the drone body 3. The protective component 6 includes a protective electric cylinder 61, a protective rack 62, a protective gear 63, a protective rod 64, and a protective cloth 65.

[0044] Two protective electric cylinders 61, two protective racks 62, two protective gears 63, and two protective rods 64 are provided, and they are symmetrically arranged on both sides of the propeller of the UAV body 3. The protective electric cylinder 61 is fixed to the connecting seat 42. The protective racks 62 are fixed to the movable end of the protective electric cylinder 61. The protective gears 63 mesh with the protective racks 62 and are rotatably connected to the connecting seat 42. One end of the protective rod 64 is fixed to the protective gear 63 through a rotating shaft, and the other end is fixed to the edge of the protective cloth 65. The edge of the protective cloth 65 away from the protective rod 64 is fixed to the UAV body 3. The two protective rods 64 can unfold the protective cloth 65 above the propeller of the UAV body 3.

[0045] In this embodiment, in order to enhance the protective capability of the protective cloth 65, the protective cloth 65 can be unfolded and placed in a U-shape over the propeller of the drone body 3.

[0046] When the outdoor weather is severe, such as heavy rain or strong winds, the protective electric cylinder 61 extends, which drives the protective rack 62 to move. The protective rack 62 drives the protective gear 63 to rotate, and the protective gear 63 can drive the protective rod 64 to swing away from the detector body 2. The two protective rods 64 can unfold the protective cloth 65 and cover the propeller of the drone body 3 to protect the propeller of the drone body 3 from damage.

[0047] Reference Figure 2 In order to further secure the connecting seat 42 and the mounting seat 41 in severe weather, the protective electric cylinder 61 is connected to a reinforcing component 7, which includes a reinforcing head 71 and a reinforcing ring 72.

[0048] ReferenceFigure 2 and Figure 5 The number of reinforcing heads 71 ​​is the same as the number of protective electric cylinders 61. Each reinforcing head 71 is fixedly connected to the movable end of the protective electric cylinder 61. Two reinforcing nails 73 are fixedly connected to each reinforcing head 71. A reinforcing ring 72 is fixedly connected to the mounting base 41 and sleeved on the connecting base 42. A reinforcing rubber layer 74 is fixedly connected to the inner wall of the reinforcing ring 72. When the protective electric cylinder 61 extends, it can drive the reinforcing head 71 to press against the reinforcing rubber layer 74 and drive the reinforcing nails 73 to be driven into the reinforcing rubber layer 74. When the protective electric cylinder 61 extends, it can drive the protective rod 64 to unfold the protective cloth 65, so that the unfolding of the protective cloth 65 and the further reinforcement of the connecting base 42 relative to the mounting base 41 can be carried out simultaneously.

[0049] When the protective electric cylinder 61 extends due to severe weather, the protective electric cylinder 61 can also drive the reinforcing head 71 to abut against the reinforcing rubber layer 74, and can make the reinforcing nail 73 stick into the reinforcing rubber layer 74 to further fix the connecting seat 42 and the mounting seat 41, making it even more difficult for the connecting seat 42 to rotate relative to the mounting seat 41, so that the detector body 2 can be stably installed on the mounting column 1 in severe weather.

[0050] Reference Figure 2 and Figure 3 In order to enable the detector body 2 and the drone body 3 to easily obtain power, the drone body 3 is equipped with a power supply component 8, which includes a solar panel 81 and a battery 82. The solar panel 81 is electrically connected to the battery 82, and the battery 82 is electrically connected to the detector body 2, the drone body 3 and the magnetic control unit 44 respectively.

[0051] The battery 82 is charged by the solar panel 81, so that the battery 82 can be automatically replenished and the detector body 2, the drone body 3 and the magnetic control unit 44 can use clean energy.

[0052] Reference Figure 2 and Figure 3 In this embodiment, the solar panel 81 is located in the middle of the UAV body 3, and there are four batteries 82, which are evenly arranged around the solar panel 81. In this embodiment, the batteries 82 are electrically connected to the electromagnetic ring 441 of the magnetic control unit 44. In this embodiment, the batteries 82 are also electrically connected to the camera 5 and the protective electric cylinder 61.

[0053] The implementation principle of an air quality detection device according to an embodiment of this application is as follows: In normal use, the detector body 2 can perform fixed-point air detection on the mounting column 1. When it is necessary to expand the detection range, the drone body 3 is started, the magnetic control unit 44 opens the snap-fit ​​hole 4311, and the drone body 3 rotates in the reverse direction to drive the snap-fit ​​connector 421 to disengage from between the first snap ring 431 and the second snap ring 432 along the sealing plate 433, so that the drone body 3 can carry the detector body 2 to fly, enabling the detector body 2 to cruise and detect the air, thus expanding the detection range of the detector body 2. After completing the cruise detection, the drone body 3 carries the detector body 2 back to the mounting column 1, and the drone body 3 rotates in the forward direction to drive the snap-fit ​​connector 421 to slide into between the first snap ring 431 and the second snap ring 432 along the sealing plate 433. After the drone stops, the magnetic control unit 44 closes the snap-fit ​​hole 4311, and the detector body 2 continues to perform fixed-point detection, so that fixed-point detection and area detection can be used in combination. Area detection is performed intermittently during the fixed-point detection process, thereby improving the reliability of the detection results.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
