DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it is a structural diagram of a rotorless UAV structure provided by an embodiment of the present invention, comprising a UAV body 1, a support frame 11 is provided on the bottom wall of the UAV body 1, a plurality of groups of connecting rods 12 distributed in an annular shape are fixedly installed on the side wall of the UAV body 1, a fixed cylinder 2 is fixedly installed on one end of the connecting rod 12 away from the UAV body 1, the upper and lower ends of the fixed cylinder 2 are connected, a jet engine 21 is fixedly installed in the fixed cylinder 2, a protective ring 3 located above the jet engine 21 is rotatably installed in the inner cavity of the fixed cylinder 2, and the surface of the protective ring 3 is provided with evenly distributed mesh holes, the two opposite inner side walls of the fixed cylinder 2 are respectively provided with annular grooves, and the two ends of the protective ring 3 are respectively rotatably installed in the annular grooves, a transmission column 4 is rotatably installed between the two opposite side walls of the fixed cylinder 2, the transmission column 4 passes through the inner cavity of the protective ring 3, one end of the transmission column 4 extends to the outside of the fixed cylinder 2 and is connected to a motor 41, and a rotating component 5 that cooperates with the protective ring 3 is provided on the surface of the transmission column 4, and the rotating component 5 is used to rotate. In order to control the rotation of the protective ring 3 in the fixed cylinder 2, a collection box 6 is fixedly installed on the side wall of the fixed cylinder 2, and a chip removal port 61 connected to the collection box 6 is opened on the side wall of the fixed cylinder 2. A cleaning mechanism 7 that cooperates with the protective ring 3 is arranged in the fixed cylinder 2, and the cleaning mechanism 7 includes a brush 71, a positioning component 72, a transmission component 73 and a guide assembly 74. The positioning component 72 is located between the two opposite side walls of the fixed cylinder 2 and is connected to the brush 71. The positioning component 72 is used to control multiple groups of brushes 71 to be in the inner cavity of the protective ring 3. The transmission component 73 is located in the inner cavity of the protective ring 3 and is connected to the positioning component 72. When the protective ring 3 rotates, the transmission component 73 controls the brush 71 to reciprocate at the mesh on the surface of the protective ring 3 by cooperating with the positioning component 72. The guide assembly 74 is located on the bottom wall of the collection box 6 and is connected to the side wall of the fixed cylinder 2. The guide assembly 74 is used to suck impurities in the collection box 6 to the bottom of the fixed cylinder 2 and discharge them.

[0025] When in use, the jet engine 21 is started, the jet engine 21 sucks and compresses the air above the fixed cylinder 2, and then the compressed air is ejected at high speed from the bottom opening of the fixed cylinder 2. The jet engine 21 generates an upward thrust and then pushes the drone body 1 to fly upward. When the jet engine 21 sucks the air above the fixed cylinder 2, the protective ring 3 can perform all-round screening and filtering of impurities attached to the air. When the protective ring 3 screens and filters the impurities, the motor 41 drives the transmission column 4 to rotate in the inner cavity of the fixed cylinder 2. The transmission column 4 cooperates with the rotating component 5 to drive the protective ring 3 to rotate synchronously in the fixed cylinder 2. The protective ring 3 rotates When rotating, the mesh holes in different directions can be continuously replaced to filter the air. When the protective ring 3 rotates, it will rotate synchronously with the impurities attached to its surface. When the protective ring 3 rotates, the transmission component 73 and the positioning component 72 cooperate with each other to control the brush 71 to move back and forth in the horizontal direction. The brush 71 moves back and forth from the inner cavity of the protective ring 3 toward the outside of the protective ring 3. The brush 71 can clean the impurities blocked in the mesh holes and the impurities attached to the surface of the protective ring 3 into the chip discharge port 61 and then fall into the collection box 6. The compressed air is discharged at a high speed from the lower half of the fixed cylinder 2. The suction generated by the air flow cooperates with the guide assembly 74 to automatically discharge the impurities in the collection box 6.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the rotating assembly 5 includes a gear ring 51 fixedly mounted on the inner wall of the protective ring 3, and a transmission gear plate 52 is fixedly mounted on the surface of the transmission column 4, and the transmission gear plate 52 is meshingly connected with the gear ring 51.

[0027] When in use, the motor 41 drives the transmission column 4 to rotate and then drives the transmission gear plate 52 to rotate. The transmission gear plate 52 is meshed with the gear ring 51 to drive the protection ring 3 to continuously rotate in the inner cavity of the fixed cylinder 2. The mesh on the surface of the protection ring 3 can continuously filter impurities in the air.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the positioning assembly 72 includes slide grooves 721 respectively opened on the two opposite inner walls of the fixed cylinder 2, and a sliding block 722 is installed in the slide groove 721 along the horizontal direction. The sliding blocks 722 on both sides extend to the outside of the slide groove 721 and are fixedly installed with a supporting plate 723, and multiple groups of brushes 71 are evenly distributed on the surface of the supporting plate 723.

[0029] Multiple groups of sliding blocks 722 support and position the supporting plate 723. The supporting plate 723 is in a vertical state in the inner cavity of the protective ring 3. The sliding block 722 moves in the slide groove 721, thereby controlling the supporting plate 723 to move in the horizontal direction. When in use, the transmission assembly 73 controls the supporting plate 723 to move back and forth in the horizontal direction, and the supporting plate 723 drives the brush 71 to move synchronously. When moving, the brush 71 can clean the impurities blocked on the surface of the protective ring 3, and then clean the impurities into the collection box 6.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, as a preferred embodiment of the present invention, the transmission assembly 73 includes a fixing frame 731 fixedly installed on the inner wall of the fixing cylinder 2 and located in the inner cavity of the protective ring 3, a rotating rod 732 is rotatably installed between the inner wall of the fixing frame 2 and the fixing frame 731, one end of the rotating rod 732 extends to the outside of the fixing frame 731 and is fixedly installed with a fixing disk 733, a push-pull rod 734 is rotatably installed on the surface of the fixing disk 733 at a position deviating from the center of the circle, and one end of the push-pull rod 734 is rotatably connected to the side wall of the bearing plate 723 away from the fixing disk 733, and synchronous toothed discs 735 are fixedly installed on the surfaces of the transmission column 4 and the rotating rod 732, and synchronous belts 736 are arranged on the surfaces of the two sets of synchronous toothed discs 735.

[0031] The transmission column 4 drives the synchronous gear plate 735 to rotate. The two sets of synchronous gear plates 735 cooperate with the synchronous belt 736 to drive the rotating rod 732 to rotate. The rotating rod 732 drives the fixed plate 733 to rotate synchronously. When the fixed plate 733 rotates, it cooperates with the push-pull rod 734 to push the bearing plate 723 to reciprocate in the horizontal direction.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the drainage assembly 74 includes a bottom hole 741 opened on the bottom wall of the collection box 6, and the side wall of the fixed cylinder 2 is provided with a suction hole 742 located below the jet engine 21, and the suction hole 742 is distributed obliquely downward inward from the outer wall of the fixed cylinder 2, and a drainage pipe 743 is fixedly installed between the bottom hole 741 and the suction hole 742.

[0033] When the compressed air is discharged from the lower half of the fixed cylinder 2, a large suction force will be generated in the suction hole 742. The exhaust pipe 743 and the suction hole 742 cooperate with each other to generate suction in the collection box 6, thereby sucking impurities attached to the surface of the protective ring 3 into the collection box 6. The impurities move to the lower half of the fixed cylinder 2 through the exhaust pipe 743 and are automatically discharged.

[0034] like Figure 1 , Figure 3, Figure 4 As shown, as a preferred embodiment of the present invention, a debris removal opening 8 is opened on the side wall of the fixed cylinder 2, and the debris removal opening 8 is located above the contact point between the protective ring 3 and the side wall of the fixed cylinder 2.

[0035] When larger impurities are screened on the surface of the protection ring 3 , the larger impurities can be automatically discharged to the outside of the fixed cylinder 2 through the impurity removal port 8 when the protection ring 3 rotates.

[0036] like Figure 1 , Figure 3 As shown, as a preferred embodiment of the present invention, a heat dissipation component 9 that cooperates with the fixed tube 2 is arranged inside the drone body 1, and the heat dissipation component 9 includes an annular heat dissipation cavity 91 opened inside the drone body 1, and a heat dissipation hole 92 connected with the heat dissipation hole 91 is opened inwardly on the side wall of the drone body 1, and an air intake hole 94 is opened on the side wall of the fixed tube 2, and the air intake hole 94 is distributed obliquely upward inward from the outer side wall of the fixed tube 2, and an air supply pipe 93 connected with the heat dissipation cavity 91 is fixedly installed on the surface of the drone body 1, and the end of the air supply pipe 93 away from the drone body 1 is connected with the air intake hole 94.

[0037] During use, when the compressed air is discharged at high speed from the lower half of the fixed tube 2, a small amount of air will flow into the air inlet 94, and the high-speed flowing air will flow through the air duct 93 into the heat dissipation cavity 91, thereby accelerating the air flow speed in the heat dissipation cavity 91, and efficiently dissipating the heat of the drone body 1.

[0038] like Figure 1 , Figure 3 As shown, as a preferred embodiment of the present invention, a baffle 10 located below the air inlet 94 is fixedly installed on the inner wall of the fixed cylinder 2.

[0039] The working principle of the present invention is: when in use, the jet engine 21 is started, the jet engine 21 sucks and compresses the air above the fixed cylinder 2, and then the compressed air is ejected at high speed from the bottom opening of the fixed cylinder 2. The jet engine 21 generates an upward thrust and then pushes the drone body 1 to fly upward. When the jet engine 21 sucks the air above the fixed cylinder 2, the protective ring 3 can perform all-round screening and filtering of impurities attached to the air. When the protective ring 3 screens and filters the impurities, the motor 41 drives the transmission column 4 to rotate in the inner cavity of the fixed cylinder 2, and the transmission gear disc 52 and the gear ring 51 are meshed and transmitted, which can drive the protective ring 3 to continuously rotate in the inner cavity of the fixed cylinder 2. The mesh on the surface of the protective ring 3 can continuously screen and filter impurities in the air.

[0040] The transmission column 4 drives the synchronous toothed disc 735 to rotate. The two sets of synchronous toothed discs 735 cooperate with the synchronous belt 736 to drive the rotating rod 732 to rotate. The rotating rod 732 drives the fixed disc 733 to rotate synchronously. The fixed disc 733 cooperates with the push-pull rod 734 when rotating, and can push the bearing plate 723 to move back and forth in the horizontal direction. The bearing plate 723 drives the brush 71 to move synchronously. When the brush 71 moves, it can clean the impurities blocked on the surface of the protective ring 3, and then clean the impurities into the collection box 6. When the compressed air is discharged from the lower half of the fixed cylinder 2, it will generate a large suction force in the suction hole 742. The guide pipe 743 cooperates with the suction hole 742 to generate suction force in the collection box 6, and then the impurities attached to the surface of the protective ring 3 can be sucked into the collection box 6. The impurities pass through the guide pipe 743 and move to the lower half of the fixed cylinder 2 and are automatically discharged. When the compressed air is discharged at high speed from the lower half of the fixed tube 2, a small amount of air will flow into the air inlet 94, and the high-speed flowing air will flow into the heat dissipation cavity 91 through the air duct 93, thereby accelerating the air flow speed in the heat dissipation cavity 91, and efficiently dissipating the heat of the drone body 1.

[0041] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
