[0032] Referring to Figure 2 and Figure 4 The magnetic control part 44 is arranged between the mounting seat 41 and the connecting seat 42, and is used for controlling the opening and closing of the clamping gap based on the starting state of the unmanned aerial vehicle body 3; in the state that the connecting seat 42 is close to the mounting seat 41, when the unmanned aerial vehicle body 3 is in the starting state, the magnetic control part 44 opens the clamping gap, so that the clamping joint 421 enters or exits the clamping gap, and when the unmanned aerial vehicle body 3 is in the shutdown state, the magnetic control part 44 closes the clamping gap, so as to limit the clamping joint 421 from being separated from the clamping part 43; in the case that the clamping gap is opened, the clamping joint 421 can be positively rotated and clamped on the clamping part 43 under the drive of the unmanned aerial vehicle body 3, and the clamping joint 421 can be reversely rotated and separated from the clamping part 43 under the drive of the unmanned aerial vehicle body 3.

[0033] In the normal state, the unmanned aerial vehicle body 3 and the detector body 2 are connected to the mounting seat 41 through the connecting seat 42, and the detector body 2 can perform point air detection; when it is necessary to expand the detection range, the unmanned aerial vehicle body 3 is started, the magnetic control part 44 can open the clamping gap, and the started unmanned aerial vehicle body 3 can drive the clamping joint 421 to reversely rotate, so that the clamping joint 421 exits the clamping part 43, the connection between the mounting seat 41 and the connecting seat 42 can be released, and the unmanned aerial vehicle body 3 can carry the detector body 2 to fly, so as to perform regional air detection in a cruising manner, thereby expanding the detection range of the air quality detection device.

[0035] Under the cooperation of the magnetic control part 44 and the unmanned aerial vehicle body 3, the connection and disconnection between the connecting seat 42 and the mounting seat 41 can be automatically realized, without manual on-site operation, the overall automation degree of the detection device is improved, the manual labor intensity is reduced, and the convenience of using the detection device is enhanced.

[0036] The spot detection data can reflect the long-term air quality around the spot position of the detector body 2, and the cruise detection data can periodically reflect the air quality around the area of the detector body 2.

[0037] Specifically, referring to Figure 4 , the clamping part 43 comprises a first clamping ring 431, a second clamping ring 432 and a closing plate 433.

[0038] Referring to Figure 3 and Figure 4 , the first clamping ring 431 and the second clamping ring 432 are both fixedly connected to the hole wall of the mounting hole 411 in the middle of the mounting seat 41, the first clamping ring 431 is located above the second clamping ring 432, the first clamping ring 431 is provided with a clamping hole 4311, the clamping hole 4311 forms a clamping notch of the clamping part 43, and the closing plate 433 is hinged to the clamping hole 4311 through a hinge shaft 434, and the closing plate 433 is used to open or close the clamping hole 4311. Among them, the wall surface of the clamping hole 4311 close to the hole wall of the mounting hole 411 is flush with the hole wall of the mounting hole 411.

[0039] The magnetic control part 44 is used to control the closing plate 433 to swing forward and abut on the second clamping ring 432 to open the clamping hole 4311, and the magnetic control part 44 is used to control the closing plate 433 to swing reversely to close the clamping hole 4311, and the clamping head 421 is provided with a disengaging slope 422 which can slide onto the closing plate 433 to assist the clamping head 421 to disengage from between the first clamping ring 431 and the second clamping ring 432.

[0040] When it is needed to connect the mounting seat 41 and the connecting seat 42, the magnetic control part 44 controls the closing plate 433 to swing forward and abut on the second clamping ring 432, the clamping head 421 can rotate to the clamping hole 4311 in the process of forward rotation, the clamping head 421 can slide into the first clamping ring 431 and the second clamping ring 432 along the closing plate 433, and can continuously rotate between the first clamping ring 431 and the second clamping ring 432; after the clamping head 421 slides into the first clamping ring 431 and the second clamping ring 432, the unmanned aerial vehicle body 3 is stopped, the magnetic control part 44 controls the closing plate 433 to swing and close the clamping hole 4311, so that the clamping head 421 is difficult to disengage from between the first clamping ring 431 and the second clamping ring 432 from the clamping hole 4311.

[0041] Under the one-way guiding effect of the closing plate 433, the forward rotating clamping head 421 is difficult to be pulled out of the first clamping ring 431 and the second clamping ring 432, so that the detection direction of the detector body 2 can be adjusted under the driving of the UAV body 3; when it is needed to release the connection between the mounting seat 41 and the connecting seat 42, the magnetic control part 44 controls the closing plate 433 to swing forward and abut on the second clamping ring 432, the UAV body 3 drives the clamping head 421 to rotate reversely, the reversely rotating clamping head 421 can slide onto the closing plate 433 through the escape slope 422, and under the guiding effect of the closing plate 433, the clamping head 421 can be pulled out of the first clamping ring 431 and the second clamping ring 432, so that the clamping head 421 can be pulled out of the first clamping ring 431 and the second clamping ring 432 under the driving of the UAV body 3.

[0042] With reference to Figure 3 , in order to make the clamping head 421 easily enter the clamping hole 4311, the side of the first clamping ring 431 away from the second clamping ring 432 is fixedly connected with a guide plate 435, the guide plate 435 is arranged close to the clamping hole 4311, the guide plate 435 is curved in an arc shape, and the guide plate 435 is used for guiding the clamping head 421 to enter the clamping hole 4311 when the clamping head 421 rotates forward.

[0043] The arc-shaped guide plate 435 can guide and limit the rotating clamping head 421, so that the clamping head 421 can only slide along the closing plate 433, the clamping head 421 is not easy to slide through the clamping hole 4311 when rotating to the clamping hole 4311, so that the clamping head 421 is not easy to miss the clamping hole 4311, and the clamping head 421 is more easily slid into the clamping hole 4311.

[0044] Specifically, with reference to Figure 3 , the magnetic control part 44 comprises an electromagnetic ring 441, a permanent magnet block 442, a control rack 443 and a control gear 444.

[0045] With reference to Figure 3 and Figure 4 , the electromagnetic ring 441 is fixedly embedded on the connecting seat 42, the permanent magnet block 442 is slidingly arranged in a control sliding groove 412 formed in the mounting seat 41, and the sliding direction is a vertical direction. When the UAV body 3 is powered on, the polarities of the sides close to each other of the electromagnetic ring 441 and the permanent magnet block 442 are the same, and when the UAV body 3 is powered off, the polarities of the sides close to each other of the electromagnetic ring 441 and the permanent magnet block 442 are opposite.

[0046] The control rack 443 and the control gear 444 are arranged in a transmission groove 413 of the mounting base 41, the transmission groove 413 is communicated with the control sliding groove 412, the control rack 443 is engaged with the control gear 444, the control rack 443 is fixedly connected with a connecting rod 4431, the connecting rod 4431 is fixedly connected with the permanent magnet block 442, and the control gear 444 is fixedly connected with the hinged shaft 434.

[0047] When the unmanned aerial vehicle body 3 is started, the electromagnetic ring 441 and the permanent magnet block 442 can be in a state of mutual repulsion, the permanent magnet block 442 can slide down to the groove bottom of the control sliding groove 412 under the magnetic thrust, 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 hinged shaft 434 to rotate, and the hinged shaft 434 can drive the closing plate 433 to swing, so that the clamping hole 4311 is opened; when the unmanned aerial vehicle body 3 is stopped, the electromagnetic ring 441 and the permanent magnet block 442 can be in a state of mutual adsorption, the permanent magnet block 442 can slide up to the slot position of the control sliding groove 412, the permanent magnet block 442 can drive the closing plate 433 to close the clamping hole 4311 through the control rack 443 and the control gear 444, and the magnetic attraction force of the electromagnetic ring 441 and the permanent magnet block 442 can also exert a fixing force on the connecting base 42 and the mounting base 41, so that the detection instrument body 2 is not easy to rotate freely in a normal state.

[0048] With reference to Figure 4 , in order to facilitate the butt joint installation of the mounting base 41 and the connecting base 42, the mounting surfaces of the mounting base 41 and the connecting base 42 close to each other are conical, the connecting base 42 is easy to be positioned relative to the mounting base 41 through the conical mounting surfaces of the connecting base 42 and the mounting base 41, which is conducive to the rotation insertion of the clamping head 421 into the mounting hole 411, thereby facilitating the butt joint of the connecting base 42 and the mounting base 41 and improving the connection efficiency of the connecting base 42 and the mounting base 41.

[0049] With reference to Figure 2 and Figure 3 , in order to reduce the friction resistance of the unmanned aerial vehicle body 3 driving the connecting base 42 to rotate, the number of the clamping head 421, the clamping hole 4311, the permanent magnet block 442, the control rack 443 and the control gear 444 is consistent in pairs, and the permanent magnet block 442 is uniformly provided with a plurality of permanent magnet blocks around the axis direction of the mounting base 41.

[0050] The plurality of permanent magnet blocks 442 uniformly arranged can form a stable and centered magnetic thrust on the electromagnetic ring 441, which on the one hand helps the clamping head 421 to be centrally inserted into the mounting hole 411, and on the other hand helps to reduce the friction resistance of the connecting base 42 relative to the mounting base 41 or the friction resistance of the clamping head 421 relative to the first clamping ring 431, so that the unmanned aerial vehicle body 3 is easy to drive the clamping head 421 to rotate.

The two protection rods 64 can unfold the protection cloth 65, and make the protection cloth 65 cover the propellers of the unmanned aerial vehicle body 3, so as to protect the propellers of the unmanned aerial vehicle body 3 from being damaged.
