[0038] As a preferred embodiment of the present invention: the rotation control unit includes an adjusting motor, which is installed on the drone body through a motor seat, and the output end of the adjusting motor is transmission-connected to an adjusting drive gear, and evenly distributed second convex teeth are installed on the inner side of the annular plate, and the second convex teeth are engaged with the adjusting drive gear.

[0039] The beneficial effects of the present invention are:

[0040] 1. The present invention sets up a camera anti-interference structure, which can provide a protective effect through the transparent barrier film when the camera mechanism needs to be protected against interference, such as in harsh environments; at the same time, the elastic arc strip can provide a certain supporting capacity; when the camera anti-interference structure needs to be retracted, the third annular frame can be controlled to move along the rotation direction of the elastic arc strip, and the one-way limit teeth can block the movable teeth, and then the movable teeth can be used to drive the second annular frame to rotate outside the first annular frame through the one-way limit teeth; since the elastic arc strip is a spiral arc structure, and since the top end of the elastic arc strip is fixed, when the second annular frame rotates, each elastic arc strip is tightened and deformed upward, so that the second annular frame and the first annular frame move upward along the guidance of the vertical pole, thereby achieving the storage effect.

[0041] 2. The present invention is capable of operating based on a rotational drive motor by providing structures such as bar teeth, thereby driving the third annular frame to rotate. Moreover, since the third annular frame itself will move upward when the second annular frame is moved by the movable teeth and the one-way limit teeth, the bar teeth can prevent the first convex teeth from disengaging after moving upward, thereby improving reliability.

[0042] 3. The present invention provides a cleaning component, which can use the brush plate to clean the transparent baffle film when the third annular frame rotates in the direction opposite to the rotation direction of the elastic arc strip. Since the one-way limiting teeth limit the movable teeth in one direction, when the third annular frame rotates in the direction opposite to the rotation direction of the elastic arc strip, the inclined surface of the movable tooth contacts the inclined surface of the one-way limiting tooth, thereby compressing the spring and making the movable tooth avoid it, and there will be no jamming or the like, thereby ensuring smooth cleaning.

[0043] 4. The present invention provides structures such as elastic bags and air bags, so that the brush head of the brush plate does not contact the transparent barrier film when on standby. When cleaning is required, the arc plate is driven to rotate by the third annular frame. As the structure continues to rotate, the air bag contacts the pressure wheel and is squeezed by the pressure wheel. The gas in the air bag is squeezed into the elastic bag, and the elastic bag expands, thereby pushing the brush plate toward the transparent barrier film, so that the brush head can contact the transparent barrier film for easy cleaning.

[0044] 5. Since the present invention is provided with an exhaust micro-tube, the exhaust can be slowly discharged based on the exhaust micro-tube during the process. After the third ring frame stops rotating and cleaning for a period of time, the gas has enough time to be discharged from the exhaust micro-tube, and the elastic bag returns to its normal shape, thereby driving the brush plate to reset and allowing the brush head to separate from the transparent baffle.

[0045] 6. The present invention provides a rotor anti-interference structure, which can drive the upper ring frame to move upward through the lifting mechanism when protection is needed, and each slide bar slides in the side bracket. The lower ring frame, the upper ring frame and the slide bar form a cage structure to provide anti-interference protection for the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0056] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0057] Example 1:

[0058] An anti-interference inspection drone, such as Figure 1-8 As shown, it includes: a drone body 1, a camera mechanism is installed at the bottom of the drone body 1, a camera anti-interference structure is set at the bottom of the drone body 1, and the camera anti-interference structure is located outside the camera mechanism; the camera anti-interference structure includes:

[0059] A vertical pole 26 is fixed to the outer wall of the bottom of the drone body 1;

[0060] A first annular frame 18, which is slidably connected to the outer wall of the vertical rod 26;

[0061] The second annular frame 19 is rotatably mounted on the outside of the first annular frame 18. An annular cavity is provided at the bottom of the drone body 1. A transparent baffle 28 is fixed in the annular cavity. The bottom end of the transparent baffle 28 is fixed to the top of the second annular frame 19.

[0062] An elastic arc strip 27, one end of which is fixed in the annular cavity, and the other end of which is fixed to the top outer wall of the second annular frame 19. The elastic arc strip 27 has a spiral arc structure, and multiple elastic arc strips 27 are arranged in a circumferential distribution. A transparent barrier film 28 is located on the outside of each elastic arc strip 27;

[0063] The third annular frame 5 is rotatably mounted on the outside of the second annular frame 19. A tooth seat is provided at the bottom of the third annular frame 5. A movable tooth 31 is movably mounted in the tooth seat via a spring. A one-way limiting tooth 29 is fixed to the bottom of the second annular frame 19. The one-way limiting tooth 29 is located on the movement path of the movable tooth 31.

[0064] A rotation drive unit, which is mounted on the drone body 1 and is used to drive the third annular frame 5 to rotate;

[0065] Among them, when the second annular frame 19 is not subjected to external force, based on the support of the elastic arc strip 27, the bottom surface height of the second annular frame 19 is lower than the bottom of the camera mechanism, and the one-way limiting tooth 29 blocks the movable tooth 31 when the movable tooth 31 moves in the rotation direction of the elastic arc strip 27;

[0066] By setting up the camera anti-interference structure, when the camera mechanism needs to be protected against interference, for example, in harsh environments, the transparent blocking film 28 can play a protective role; at the same time, the elastic arc strip 27 can play a certain supporting role; when the camera anti-interference structure needs to be retracted, the third annular frame 5 can be controlled to move along the rotation direction of the elastic arc strip 27, and the one-way limiting tooth 29 can block the movable tooth 31, and then the movable tooth 31 can be used to move the second annular frame 19 to rotate outside the first annular frame 18 through the one-way limiting tooth 29; since the elastic arc strip 27 is a spiral arc structure, and since the top end of the elastic arc strip 27 is fixed, when the second annular frame 19 rotates, each elastic arc strip 27 is tightened and deformed upward, so that the second annular frame 19 and the first annular frame 18 move upward along the guidance of the vertical rod 26; thereby achieving the retraction effect;

[0067] When the camera anti-interference structure is needed, the third annular frame 5 is controlled to rotate in the opposite direction, and the second annular frame 19 and other structures can be reset based on the resilience of the elastic arc strip 27.

[0068] Preferably, a first limit block is adjustably mounted on the bottom end of the vertical rod 26;

[0069] In order to facilitate the driving of the third annular frame 5 to rotate; Figure 4 As shown, the rotation drive unit includes:

[0070] The rotation drive motor 21 is installed on the drone body 1;

[0071] The top of the rotating drum 10 is connected to the output end of the rotating drive motor 21 through a shaft. The outer side of the rotating drum 10 is provided with circumferentially distributed strip teeth 20. The outer side of the third annular frame 5 is provided with first convex teeth. The strip teeth 20 are meshed with the first convex teeth.

[0072] By providing structures such as the bar teeth 20, the third annular frame 5 can be driven to rotate based on the rotation drive motor 21. Moreover, when the third annular frame 5 moves the second annular frame 19 through the movable teeth 31 and the one-way limit teeth 29, it itself will also move upward. Therefore, the bar teeth 20 can prevent the first convex teeth from disengaging after moving upward, thereby improving reliability.

[0073] In order to facilitate the collection of image information; Figure 2 、 Figure 4 As shown, the camera mechanism includes:

[0074] Mounting frame 25, the mounting frame 25 is installed at the bottom of the drone body 1;

[0075] The camera assembly 9 is rotatably mounted on the mounting frame 25 via a rotating bracket;

[0076] The camera adjustment motor 23 is installed on one side of the mounting bracket 25 , and the output end of the camera adjustment motor 23 is connected to the shaft of the rotating bracket.

[0077] In order to facilitate the cleaning of the transparent barrier film 28; Figure 5 、 Figure 7 、 Figure 8 As shown, a cleaning assembly is installed on the top outer wall of the third annular frame 5, and the cleaning assembly includes:

[0078] The arc-shaped plate 22 is fixed to the top outer wall of the third annular frame 5;

[0079] The brush plate 33 is installed on the side of the curved plate 22 close to the transparent barrier film 28, and the brush plate 33 is provided with evenly distributed brush heads;

[0080] By setting up a cleaning component, the brush plate 33 can be used to clean the transparent blocking film 28 during the process of the third annular frame 5 rotating in the opposite direction of the elastic arc strip 27. Since the one-way limiting tooth 29 limits the movable tooth 31 in one direction, the inclined surface of the movable tooth 31 contacts the inclined surface of the one-way limiting tooth 29 during the process of the third annular frame 5 rotating in the opposite direction of the elastic arc strip 27, thereby compressing the spring and making the movable tooth 31 avoid getting stuck, thereby ensuring smooth cleaning.

[0081] In order to better clean; Figure 7 、 Figure 8As shown, a guide bracket 32 is fixed to the outer wall of one side of the brush plate 33, and the guide bracket 32 is slidably connected to the inner wall of the curved plate 22. An elastic bag 34 is installed between the brush plate 33 and the curved plate 22. An air bag 30 is installed on the side of the curved plate 22 away from the brush plate 33. The air bag 30 is connected to the elastic bag 34 through the mounting bracket 25. A one-way air valve 36 is provided on the connecting pipe 35. The one-way air valve 36 allows air flow from the air bag 30 to be input into the elastic bag 34 in one direction. An exhaust micro-tube 37 is provided on the top of the elastic bag 34. An air intake pipe 38 is installed on the top of the air bag 30, and a one-way air intake valve 39 is provided on the air intake pipe 38.

[0082] A pressure wheel 24 is fixed to the bottom of the drone body 1, and the pressure wheel 24 is located on the movement path of the airbag 30 during cleaning;

[0083] By providing the elastic bag 34, the air bag 30 and other structures, the brush head of the brush plate 33 does not contact the transparent barrier film 28 when in standby mode. When cleaning is required, the arc plate 22 is driven to rotate by the third annular frame 5. As the structure continues to rotate, the air bag 30 contacts the pressure wheel 24 and is squeezed by the pressure wheel 24. The gas in the air bag 30 is squeezed into the elastic bag 34, and the elastic bag 34 expands, thereby pushing the brush plate 33 toward the transparent barrier film 28, so that the brush head can contact the transparent barrier film 28 for easy cleaning.

[0084] Due to the provision of the exhaust micro-tube 37, the exhaust can be slowly discharged through the exhaust micro-tube 37 during the cleaning process. After the third annular frame 5 stops rotating for a period of time, the gas has enough time to be discharged from the exhaust micro-tube 37, and the elastic bag 34 returns to its normal shape, thereby driving the brush plate 33 to reset and the brush head to separate from the transparent blocking film 28.

[0085] Due to the provision of structures such as the one-way air intake valve 39, when the airbag 30 is squeezed, gas can be input into the elastic bag 34 through the connecting pipe 35. Based on the deformation and rebound of the airbag 30, gas can be replenished into the airbag 30 from the air intake pipe 38, facilitating continuous air supply.

[0086] In order to facilitate the anti-interference of rotor 3; Figure 3 As shown, a rotor anti-interference structure is installed on the arm 2 on the side of the drone body 1. The rotor anti-interference structure is used to protect the rotor 3 at the end of the arm 2; the rotor anti-interference structure is located outside the rotor 3; the rotor anti-interference structure includes:

[0087] The lower ring frame 12 is fixed on the machine arm 2, and a plurality of side brackets are provided on the outer side of the lower ring frame 12;

[0088] An upper ring frame 13, a plurality of slide bars 6 are fixed to the outside of the upper ring frame 13, and the slide bars 6 are connected to the inner wall of the side bracket by sliding up and down;

[0089] The drone body 1 is provided with a lifting mechanism, which is used to control the upper ring frame 13 to move upward;

[0090] By setting up a rotor anti-interference structure, when protection is needed, the upper ring frame 13 can be driven to move upward through the lifting mechanism, and each slide bar 6 slides in the side bracket. The lower ring frame 12, the upper ring frame 13 and the slide bar 6 form a cage structure, which allows airflow to pass through while blocking possible foreign objects, branches, etc., and effectively provides anti-interference protection for the rotor 3.

[0091] Preferably, a second limiting block is adjustably installed at the bottom end of the slide bar 6 .

[0092] In order to facilitate the control of the upward movement of the upper ring frame 13; Figure 1 、 Figure 3 As shown, the lifting mechanism includes:

[0093] An annular plate 14, the annular plate 14 is rotatably mounted on the outside of the drone body 1;

[0094] The annular adjustment frame 8 is fixed to the outside of the annular plate 14 and is provided with a protrusion 4;

[0095] A rotation control unit is mounted on the drone body 1 and is used to control the rotation of the annular plate 14;

[0096] The upper ring frame 13 is fixed with a connecting rod 7, one end of which is provided with a slider. Based on the rotation of the annular adjustment frame 8, the slider slides on the top of the annular adjustment frame 8; the slider is located on the motion path of the protrusion 4;

[0097] A guide column 11 is installed at the bottom of the connecting rod 7. The guide column 11 is connected to the inner wall of the arm 2 by sliding up and down. The bottom end of the guide column 11 and the arm 2 are connected by a spring.

[0098] When the annular plate 14 rotates, the protrusion 4 can push the slider upward, thereby driving the upper ring frame 13 upward. In addition, this solution can also be improved in terms of fluidity, for example, balls are provided on the inside of the side bracket to make the upward movement of the structure smoother, etc.

[0099] In order to facilitate the driving of the annular plate 14 to rotate; Figure 3 As shown, the rotation control unit includes an adjusting motor 16, which is installed on the drone body 1 through a motor seat. The output end of the adjusting motor 16 is connected to the adjusting drive gear 17, and the inner side of the annular plate 14 is equipped with evenly distributed second convex teeth 15, which are engaged with the adjusting drive gear 17.
