[0035] Embodiment 1

[0036] Jet dust removal device for unmanned aerial vehicle, as shown in the figure, includes a ground crew cabin body 1. The upper end of the ground crew cabin body 1 is provided with an opening and a cabin door 11 is installed at the opening. An elevating device 2 for parking the unmanned aerial vehicle is installed in the ground crew cabin body 1. The elevating device 2 is located directly below the cabin door 11. The elevating device 2 includes an elevating column 21 and a parking platform 22. When in use, the cabin door 11 is opened, the elevating column 21 drives the parking platform 22 to rise to the position of the cabin door opening. After the unmanned aerial vehicle moves to the parking platform 22, the parking platform 22 descends and the cabin door 11 closes. At this time, the unmanned aerial vehicle is located inside the ground crew cabin body 1 for dust removal and data monitoring. A jet dust removal device is also installed in the ground crew cabin body 1. The jet dust removal device includes a jet component 3 and a drainage component 4. The jet component 3 includes a jet pipe 31, a jet seat 32 and an adjusting nozzle 33. The jet pipe 31 is connected to an air pump 5. The jet seat 32 is a hollow circular tube body. The lower end of the jet seat 32 is hermetically fixed to the jet pipe 31. It also includes a diversion installation column 34. The diversion installation column 34 is coaxially arranged with the jet seat 32 and is fixedly installed on the inner wall of the upper end of the jet seat 32 through an installation rib 341. An air passage gap is formed between the diversion installation column 34 and the inner wall of the jet seat 32. A screw hole is provided at the outer end of the diversion installation column 34. The adjusting nozzle 33 is installed on the diversion installation column 34 through a screw cooperating with the screw hole. The adjusting nozzle 33 and the upper end port of the jet seat 32 cooperate to form an annular jet airway. By rotating the position of the adjusting nozzle 33, the size of the annular jet airway can be adjusted, thereby controlling the air output. The drainage component 4 includes a drainage pipe 41 vertically arranged at the lower part of the ground crew cabin body 1. The drainage pipe 41 is hollow and is connected to the air pump 5. A plurality of uniformly distributed drainage holes 411 are provided on the drainage pipe 41. The axial directions of the drainage holes 411 are all obliquely downward. The jet component 3 can jet air on the dust attached to the unmanned aerial vehicle to make the dust separate from the unmanned aerial vehicle, while the drainage component 4 drains the dust floating in the cabin downward to promote the precipitation of the dust and avoid secondary attachment to the unmanned aerial vehicle, thereby improving the dust removal efficiency.

[0037] The upper end opening of the jet seat 32 is a flared opening. The adjusting nozzle 33 is of an inverted frustum structure. The adjusting nozzle 33 is in clearance fit with the jet seat 32, and the taper of the outer wall of the adjusting nozzle 33 is the same as that of the opening of the jet seat 32.

[0038] The outer wall of the adjusting nozzle 33 is provided with convex ribs 331. The convex ribs 331 are circumferentially distributed on the outer wall of the adjusting nozzle 33. Through the arrangement of the convex ribs 331, the annular air passage can be effectively divided, making the ejected gas more powerful and more targeted.

[0039] It also includes a jet support 6. The jet support 6 includes a cross frame 61 and multiple vertical rods 62. The cross frame 61 is an annular frame and is horizontally arranged. The cross frame 61 surrounds the elevating device 2. The vertical rods 62 connect the cross frame 61 and the top of the ground crew cabin body 1. The jet component 3 and the air pump 5 are installed on the upper end of the cross frame 61. The drainage component 4 is installed on the lower end of the cross frame 61 and extends downward.

[0040] The inside of the cross frame 61 is hollow. The air pump 5 is communicated with the inner cavity of the cross frame 61. The air jet pipe 31 is an arc-shaped pipe. The arc-shaped setting of the air jet pipe 31 is beneficial to jet air onto the drone. The lower end of the air jet pipe 31 is communicated with the inner cavity of the cross frame 61. The air jet pipe 31 and the cross frame 61 are connected through a sealing ring.

[0041] The drainage pipe 41 is communicated with the inner cavity of the cross frame 61. There are multiple drainage pipes 41 and they are evenly distributed on the cross frame 61. The axis of the drainage hole 411 forms an angle of 50° - 75° with the horizontal plane.

[0042] There are multiple vertical rods 62. The vertical rods 62 are threaded rods. It also includes a lifting motor 63 fixedly installed on the inner wall of the ground crew cabin body 1. The lifting motor 63 is fixedly connected to the vertical rod 62 and drives the vertical rod 62 to rotate. The cross frame 61 is provided with a threaded hole that is threadedly matched with the vertical rod 62. By controlling the height position of the cross frame 61 through the lifting motor 63, jet dust removal can be performed on all aspects of the drone.

[0043] A plurality of inwardly extending baffles 7 are installed at the bottom of the ground crew cabin body 1. The baffles 7 are inclined downward and arranged staggeredly up and down. The angle between the baffle 7 and the horizontal plane is 15° - 35°. The extending end of the baffle 7 is provided with an arc-shaped baffle strip 71 that bends downward. A plurality of air permeation holes 72 are provided on the baffle 7. The air is drained downward by the drainage pipe 41. After the air encounters the baffle 7, the dust in the air is settled. At the same time, the staggered arrangement of the baffles 7 can prevent the air from surging upward extremely fast. After the dust is fully settled, the air slowly flows upward through the air permeation holes 72 to form a cycle.

[0044] It also includes a maintenance and dust removal door 12 provided on the side wall of the ground crew cabin body 1.

[0045] A baffle strip 8 is installed on the parking platform 22. There are four baffle strips 8 and they are connected to each other to form a cross-shaped baffle strip group. The baffle strip 8 cooperates with the drone and locks the position of the drone on the parking platform 22.

The adjusting screw rod 82 is installed on the parking platform 22 through a bearing seat. The adjusting screw rod 82 is perpendicularly arranged with the baffle strip 8. The adjusting screw rod 82 is connected with an adjusting motor 83. The adjusting screw rod 82 is threadedly matched with the nut seat 81 and drives the baffle strip 8 to move. The working principle is that the adjusting motor 83 drives the adjusting screw rod 82 to rotate, and through the cooperation of the nut seat 81 and the adjusting screw rod 82, the baffle strip 8 is driven to translate.

[0047] The other end of the baffle strip 8 is provided with a sliding hole 84. It also includes a sliding rod 85 arranged parallel to the adjusting screw rod 82. The sliding hole 84 cooperates with the sliding rod 85. One end of the baffle strip 8 is cooperated with the adjusting screw rod 82, and the other end of the baffle strip 8 is cooperated with the sliding rod 85, so as to ensure the translation of the baffle strip 8 and prevent the baffle strip 8 from rotating.

[0048] There are four retaining bars 8, and the four retaining bars 8 are arranged perpendicular to each other in pairs. The nut seats 81 on two parallel retaining bars 8 are respectively a left-handed nut seat and a right-handed nut seat and are matched with the same adjusting screw rod 82. Through the setting of the left-handed nut seat and the right-handed nut seat, it can be ensured that the two parallel retaining bars 8 move towards or away from each other under the drive of the adjusting motor 83, and the drone can be clamped on the parking platform 22 in all directions through the four retaining bars 8.

[0049] Anti-slip protrusions are provided on the side of the retaining bar 8 facing the drone. The anti-slip protrusions are protrusions that bend downward and extend. There are multiple anti-slip protrusions arranged on the retaining bar 8. The anti-slip protrusions are rubber protrusions and can perform anti-slip positioning on the drone.

[0050] A radio charging board is provided on the parking platform 22.
