[0040] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0041] In the description of the embodiments of the present application, space-related expressions used, such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "vertical", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or position relationship based on the orientation or position relationship shown in the specific embodiments or drawings, and are only for the convenience of describing the specific embodiments of the present application or facilitating the reader's understanding, and do not indicate or imply that the referred device or component must have a specific position, a specific orientation, or be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0042] Example, such as Figures 1 to 9As shown, an infrared detection device for an inspection drone comprises: a drone 1; a transmission shaft 2, the transmission shaft 2 being arranged below the drone 1; an infrared detection probe 3, the infrared detection probe 3 being arranged above the transmission shaft 2, a rotating motor 31 being arranged between the infrared detection probe 3 and the transmission shaft 2; a loading mechanism 4, the loading mechanism 4 being arranged below the transmission shaft 2, the loading mechanism 4 comprising a placement frame 41 with an opening, a plurality of positioning blocks 42, a closing plate 43 and an opening and closing motor 44, each of the positioning blocks 42 being arranged in the placement frame 41, the closing plate 43 being arranged at the bottom of the placement frame 41, the opening and closing motor 44 being arranged at one side of the placement frame 41, one side of the closing plate 43 being connected to the driving end of the opening and closing motor 44, a spring 45 and a pushing plate 46 being arranged at the top of the placement frame 41, the pushing plate 46 A first magnetic block 461 is provided on the moving plate 46, and a second magnetic block 421 is provided on each of the positioning blocks 42; a lifting and landing mechanism 5, wherein the lifting and landing mechanism 5 is provided on both sides of the transmission shaft 2, and each of the lifting and landing mechanisms 5 includes two supporting feet 51; the lifting and landing mechanism 5 has a lifting and landing state and a detection state, and the lifting and landing mechanism switches between the lifting and landing state and the detection state through the rotation of the transmission shaft. In the lifting and landing state, the infrared detection probe 3 is provided above the transmission shaft 2, the loading mechanism 4 is provided below the transmission shaft 2, and the bottom end height of each of the supporting feet 51 is below the bottom height of the loading mechanism 4; in the detection state, the infrared detection probe 3 is provided below the transmission shaft 2, the loading mechanism 4 is provided above the transmission shaft 2, and the bottom end height of each of the supporting feet 51 is above the top height of the infrared detection probe 3.

[0043] By setting the transmission shaft 2, the state of the lifting and lowering mechanism 5 can be changed while the positions of the infrared detection probe 3 and the loading mechanism 4 are changed. This can not only avoid the impact on the infrared detection probe 3 during landing, but also ensure that the imaging path of the infrared detection probe 4 is not obstructed while the infrared detection probe 4 rotates in a circumferential direction. When inspecting the logistics area, multiple logistics boxes on the left and right sides can be inspected at the same position at the same time, and the inspection efficiency is greatly improved.

[0044] By setting the loading mechanism 4, when the UAV 1 lands, the positioning block 42 can be placed on the ground at the inspection location, so that workers can quickly find the location of the problem point.

[0045] Each of the lifting and lowering mechanisms 5 further includes a fixing plate 52, a first gear 53 and a second gear 54. Each of the fixing plates 52 is provided with a mounting hole 521. The end of the transmission shaft 2 extends into each of the mounting holes 521. Each of the first gears 53 is provided at the end of the transmission shaft 2. The second gear 54 is provided at the top of each of the supporting feet 51. Each of the second gears 54 is correspondingly provided in each of the mounting holes 521 and meshes with each of the first gears 53. The edge of each of the mounting holes 521 is provided with corresponding matching tooth patterns.

[0046] In this embodiment, the diameter of each first gear 53 is smaller than that of each second gear 54, and the ratio of the diameter of the first gear 53 to the diameter of the second gear 54 is 0.8-0.99, preferably 0.85; when the lifting and lowering mechanism 5 switches from the lifting and lowering state to the detection state, the transmission shaft 2 rotates 180°, and under the setting of the diameter difference between the first gear 53 and the second gear 54, the rotation angle of each supporting foot 51 exceeds 180°, but still does not hinder the imaging path of the infrared detection probe 3, wherein the infrared detection probe 3 can be purchased from the market and will not be described here.

[0047] In other preferred embodiments, the diameter of each first gear 53 is the same as the diameter of each second gear 54. When the lifting and lowering mechanism 5 switches from the lifting and lowering state to the detection state, the rotation angle of the transmission shaft 2 is the same as the rotation angle of the supporting foot 51, and will not hinder the imaging path of the infrared detection probe 3.

[0048] In other preferred embodiments, the diameter of each first gear 53 is the same as the diameter of each second gear 54, and each first gear 53 is provided with a first tooth segment 531 and a second tooth segment 532. The tooth pitch of each first tooth segment 531 is greater than the tooth pitch on each second tooth segment 531, and the gear teeth on each second gear 54 are correspondingly meshed with each first gear 53. This design enables the lifting and lowering mechanism 5 to increase the initial rotation rate of each supporting leg 51 when switching from the lifting and lowering state to the detection state, so as to accelerate the flipping of each supporting leg 51 and prevent the supporting leg 51 from being stuck on the shelf.

[0049] In this embodiment, each of the supporting legs 51 is a straight rod type, which is lighter and more portable. In other preferred embodiments, each of the supporting legs 51 is arc-shaped, which can reduce the torque between the supporting legs 51 and the second gear 54 when the supporting legs 51 are subjected to force.

[0050] The height difference between the bottom end of each supporting foot 51 and the bottom of the loading mechanism 5 is greater than the thickness of one of the positioning blocks 42, and the edge of each positioning block 42 is provided with a steep angle. In the lifting and lowering state of the lifting and lowering mechanism 5, when the closing plate 43 is opened, the spring 45 cooperates with the pushing plate 46 to push the bottom positioning block 42 out of the placement frame 41, and the height difference design between the bottom end of the supporting foot 51 and the bottom of the loading mechanism 4, in conjunction with the steep angle of the edge of the positioning block 42, enables the closing plate 43 to be reclosed.

[0051] Each of the first magnetic blocks 461 and each of the second magnetic blocks 421 is annular, and there is a spacing between the edge of each positioning block 42 and the placement frame 41. The width of each of the first magnetic blocks 461 is greater than the spacing between the edge of each positioning block 42 and the placement frame 41 to ensure that the positioning blocks 42 will not be misaligned during flight shaking. At the same time, this design can reduce the coverage area of ​​the closing plate 43 to reduce weight, but can also achieve the purpose of closing the placement frame 41.

[0052] In this embodiment, each positioning block 42 is provided with a battery 422 and a sound-emitting component 423, and each positioning block 42 is provided with an elastic sheet 424 and an electrode sheet 425 that are in contact with each other, the battery 422 is electrically connected to the elastic sheet 424, and the sound-emitting component 423 is electrically connected to the electrode sheet 425. A blocking block 462 is provided at the bottom of the push plate 46 for blocking the contact between the elastic sheet 424 and the electrode sheet 425. Similarly, a blocking block 462 is also provided at the bottom of each positioning block 42. The sound-emitting component 423 is a speaker, and both the speaker and the battery 422 can be purchased on the market, which will not be described in detail here.

[0053] In other preferred embodiments, each positioning block 42 is provided with a positioning chip (not shown in the figure) and is also required to be equipped with a storage battery (not shown in the figure) for workers to find the positioning block 42 to determine the problem location. This is a conventional technical means and will not be described in detail here.

[0054] Working principle:

[0055] Before the drone 1 takes off, the landing mechanism 5 is in a landing state. After the drone 1 takes off, the transmission shaft 2 rotates, the infrared detection probe 3 rotates to the bottom of the transmission shaft 2, the loading mechanism 4 rotates to the top of the transmission shaft 2, and the supporting foot 51 flips upward. At this time, the landing mechanism 5 changes from the landing state to the detection state. When it is detected that the cargo number does not match the shelf number, the landing mechanism 5 changes from the detection state to the landing state, and the drone 1 lands on the top of the shelf or the ground, and opens the closing plate 43, and then closes the closing plate 43 again to cut between the bottom positioning block 42 and the upper positioning block 42, and squeezes the blocking block 462 between the elastic sheet 424 and the electrode sheet 425 to connect the battery 422 and the sounding member 423 to make a sound.

[0056] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
