DETAILED DESCRIPTION

[0020] The utility model will be further described in connection with the embodiment shown in the drawings:

[0021] As Figures 1 to 5As shown, a kind of unmanned plane capable of stable adsorption, including unmanned plane component 1, the unmanned plane component 1 includes unmanned plane body 11, unmanned plane rotor 12 and drive motor 13, the side of the unmanned plane body 11 is equipped with several ring mounting slots 14, the inside of each ring mounting slot 14 is connected with drive motor 13, the rotating shaft end of each drive motor 13 is connected with unmanned plane rotor 12.

[0022] The rotating shaft of drive motor 13 can drive unmanned plane rotor 12 to rotate, and unmanned plane rotor 12 changes the air pressure around in the rotating process to generate upward thrust, so that the whole unmanned plane body 11 can fly. The rotating speeds of four unmanned plane rotors 12 are different, which can change the flight direction of the whole unmanned plane body 11.

[0023] In the embodiment, the bottom of the unmanned plane component 1 is provided with an adsorption support component 2, and the inside of the adsorption support component 2 is provided with a vacuum pumping component 3.

[0024] The adsorption support component 2 includes an adsorption support frame 21 and a lithium battery 22, the adsorption support frame 21 is fixedly connected to the bottom of the unmanned plane body 11, the vacuum pumping component 3 is arranged in the inside of the adsorption support frame 21, and the bottom of the unmanned plane body 11 is also detachably provided with the lithium battery 22, and the lithium battery 22 is used to provide power for the vacuum pumping component 3. The vacuum pumping component 3 includes a vacuum pump 31, an air path support plate 32 and a vacuum pumping pipeline 33, the vacuum pump 31 is fixedly installed in the inside of the adsorption support frame 21, the end of the vacuum pump 31 is connected with the air path support plate 32, and the surface of the air path support plate 32 is provided with a plurality of vacuum pumping pipelines 33 connected to the suction cup component 5.

[0025] In the working process of the vacuum pump 31, the vacuum pump 31 drives the air pump by the motor, and air is pumped out from the inside of each suction cup component 5 along the vacuum pumping pipeline 33 to form negative pressure. The negative pressure makes the suction cup component 5 tightly contact with the surface of the object, generates strong adsorption force, firmly fixes the object, and the surface of the adsorbed object can be smooth, ground particles or uneven material.

[0026] The end of the adsorption support frame 21 is also provided with a suction cup support component 4, the inside of the suction cup support component 4 is provided with a suction cup component 5, and the position of the suction cup component 5 relative to the inside of the suction cup support component 4 can be adjusted.

[0027] The suction cup support component 4 includes a suction cup support plate 41 and a knob joint 42, the two ends of the suction cup support plate 41 are provided with a waist-shaped through hole 43, the inside of each waist-shaped through hole 43 is provided with the knob joint 42, the inside of the knob joint 42 can allow gas to pass through, one end of the knob joint 42 is connected to the suction cup component 5, and the other end of the suction cup component 5 is connected to the vacuum pumping pipeline 33.

[0028] The relative position of the knob joint 42 in the waist-shaped through hole 43 can be changed by tightening or loosening the knob joint 42, so that the position of the entire suction cup assembly 5 can also be adjusted adaptively. The user can select the position of the suction cup assembly 5 according to his own needs, so that it has better adsorption force in the working process.

[0029] The suction cup assembly 5 comprises a suction cup support shell 51, a suction cup joint 52 and a silica gel suction cup 53. The suction cup joint 52 is arranged in the suction cup support shell 51. The silica gel suction cup 53 is connected to the end of the suction cup joint 52. The bottom of the suction cup joint 52 is provided with a plurality of first air holes 54. The surface of the silica gel suction cup 53 is provided with a plurality of second air holes 55. The top of the silica gel suction cup 53 and the bottom of the suction cup support shell 51 have a first gap 56. The bottom of the silica gel suction cup 53 and the object to be sucked have a second gap 57. The air in the first gap 56 and the second gap 57 can be pumped out. The edge top and the bottom of the silica gel suction cup 53 are provided with annular asbestos 58.

[0030] During the adjustment of the continuously adjusting position of the unmanned aerial vehicle body 11, the silica gel suction cup 53 will be attached to the adsorption surface. In this process, the volume of the second gap 57 is continuously compressed, and the asbestos 58 at the edge of the silica gel suction cup 53 is also continuously compressed, so that the first gap 56 and the second gap 57 are in a relatively sealed state. At this time, the vacuum pump 31 can pump out the air in the first gap 56 and the second gap 57 upward through the first air hole 54 and the second air hole 55, so that the surface of the silica gel suction cup 53 is firmly adsorbed on the surface of the object. The compressed asbestos further enhances the adsorption effect.

[0031] The unmanned aerial vehicle body 11 in the adsorption state can be in a hovering state. At this time, the unmanned aerial vehicle rotor 12 is closed and will not fall. Then the unmanned aerial vehicle body 11 can take pictures in a long standby state.

[0032] In this embodiment, the air path in the suction cup assembly 5 is also provided with a one-way valve assembly 6. The one-way valve assembly 6 comprises a one-way valve body 61, a first sealing plate 62, a second sealing plate 63, a metal torsional spring 64 and a limiting column body 65. The first sealing plate 62 and the second sealing plate 63 are rotatably arranged in the one-way valve body 61. The first sealing plate 62 and the second sealing plate 63 are connected by a support rotating shaft 66. The surface of the support rotating shaft 66 is provided with a metal torsional spring 64. The end of the metal torsional spring 64 is attached to the surface of the first sealing plate 62 and the second sealing plate 63. The one-way valve body 61 is also provided with a limiting column body 65 for limiting the downward turning of the first sealing plate 62 and the second sealing plate 63.

[0033] Since the vacuum pump 31 needs to be closed during hovering, the endurance of the entire UAV is further improved. When the vacuum pump 31 is closed, the entire suction cup joint 52, the first gap 56 and the second gap 57 are in a vacuum negative pressure state. In order to avoid the negative pressure state from losing too fast, the metal torsion spring 64 limits the first sealing plate 62 and the second sealing plate 63 from rotating upward. After a long time of hovering, the vacuum negative pressure state will gradually weaken, and when the sensor detects that the negative pressure changes too much, the vacuum pump 31 is restarted.

[0034] It should be noted that during the hovering and adsorbing process, the suction force generated by the vacuum pump 31 needs to overcome the elastic force of the metal torsion spring 64, so that the first sealing plate 62 and the second sealing plate 63 can rotate upward around the support rotating shaft 66, so that the air in the suction cup joint 52, the first gap 56 and the second gap 57 can be smoothly sucked out.

[0035] The working principle and use method of the utility model:

[0036] During the process of continuously adjusting the position of the UAV body 11, the silica gel suction cup 53 is attached to the adsorbing surface, and in this process, the volume of the second gap 57 is continuously compressed, and the asbestos 58 at the edge of the silica gel suction cup 53 is also continuously compressed, so that the first gap 56 and the second gap 57 are in a relatively sealed state. At this time, the vacuum pump 31 can suck the air in the first gap 56 and the second gap 57 upward through the first air hole 54 and the second air hole 55, so that the surface of the silica gel suction cup 53 is firmly adsorbed on the surface of the object, and the compressed asbestos further enhances the adsorbing effect.

[0037] The UAV body 11 in the adsorbing state can be in a hovering state, and at this time, the UAV rotor 12 is closed and will not fall off, and then the UAV body 11 can take pictures in a long time standby state.

Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
