Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a protective structure of an unmanned aerial vehicle for geological exploration. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device. Drones are often used in fields such as aerial photography and geological surveys.

[0003] The patent with announcement number CN218929798U discloses "a protective structure for a UAV for geological exploration, including a UAV body, the UAV body having a built-in information collection module, and a camera arranged at the bottom of the UAV body. The utility model relates to the technical field of geological exploration equipment. An arc-shaped protective frame is connected to the bottom of the rotor arm of the UAV body through a plug-in fixing part. The horizontal height of the arc-shaped protective frame is consistent with the height of the rotor, and the rotor part can be semi-enclosed for protection, thereby effectively avoiding direct collision between the propeller and obstacles during the exploration flight, thereby causing damage to the equipment."

[0004] With respect to the above-mentioned related technologies, the inventors believe that the effect of protecting the propeller only by using an arc-shaped protective frame is poor. When the arc-shaped protective frame breaks due to excessive impact force, the broken fragments are likely to hit the propeller, thereby causing damage to the propeller. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a protective structure for a UAV for geological exploration. The specific technical solution is as follows:

[0006] A protective structure for an unmanned aerial vehicle used for geological survey comprises an unmanned aerial vehicle body, a plurality of propellers rotatably arranged on the top of the unmanned aerial vehicle body, and a protective mechanism installed on the unmanned aerial vehicle body and used to protect the propellers. The protective mechanism comprises an inner arc-shaped protective frame and an outer arc-shaped protective frame arranged on the outside of the unmanned aerial vehicle body and used to protect the propellers from the inside to the outside, and a plurality of first springs and a plurality of second rubber blocks fixedly arranged between the inner arc-shaped protective frame and the outer arc-shaped protective frame. An adjusting mechanism for controlling the distance between the propeller and the protective mechanism is arranged on the outside of the unmanned aerial vehicle body.

[0007] By adopting the above technical solution, the propeller can be provided with multiple protections through components such as the inner arc protection frame and the outer arc protection frame, so that the propeller will not directly contact obstacles in the event of a collision.

[0008] Optionally, the inner arc-shaped protective frame is located between the propeller and the outer arc-shaped protective frame, and the propeller, the inner arc-shaped protective frame and the outer arc-shaped protective frame are flush.

[0009] By adopting the above technical solution, when the outer arc-shaped protective frame is broken due to excessive force, the inner arc-shaped protective frame will block the broken fragments, making it difficult for the fragments to hit the propeller, thereby protecting the propeller.

[0010] Optionally, the adjustment mechanism includes a plurality of fixed sleeve rods fixed at the bottom of the outer side of the drone body, and a movable rod fixed at the bottom of the inner arc-shaped protective frame, one end of the movable rod is slidably arranged in the fixed sleeve rod, a sliding groove is provided in the fixed sleeve rod, and one end of the movable rod is slidably connected to the sliding groove of the fixed sleeve rod.

[0011] By adopting the above technical solution, the position of the protection mechanism can be adjusted by adjusting the position of the movable rod in the fixed sleeve rod, so that the protection mechanism after position adjustment can protect propellers of different lengths.

[0012] Optionally, a second spring is fixed to the outer wall of one end of the fixed sleeve rod, a lifting plate is fixed to one end of the second spring, a fixing rod is fixed to the side of the lifting plate close to the second spring, a plurality of positioning holes are opened in the movable rod, one end of the fixing rod passes through the fixing sleeve rod and is inserted in the positioning hole, and a counterweight is fixed to the side of the fixing sleeve rod away from the second spring.

[0013] By adopting the above technical solution, under the pulling force of the second spring, the lifting plate and the fixed rod will move toward the fixed sleeve rod side, so that one end of the fixed rod will be inserted into the corresponding positioning hole to fix the moved movable rod and the fixed sleeve rod, and fix the position of the protective mechanism after adjustment.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] 1. The propeller can be provided with multiple protections through the inner arc protection frame and the outer arc protection frame, so that the propeller will not directly contact the obstacle during the collision, and the first spring and the rubber block can buffer the drone body during the collision, so that the drone body is not easily damaged after the collision. When the outer arc protection frame is broken due to excessive force, the inner arc protection frame will block the broken fragments, so that the fragments are not easy to hit the propeller, thereby further protecting the propeller and improving the protection performance.

[0016] 2. The position of the protective mechanism can be adjusted by adjusting the position of the movable rod in the fixed sleeve rod, so that the protective mechanism after position adjustment can protect propellers of different lengths and sizes. It has a wide range of applications. People can complete the position adjustment of the protective mechanism by pulling or releasing the lifting plate and moving the movable rod, which is convenient and quick.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses a protective structure of a drone for geological exploration, referring to Figure 1-2 , including an unmanned aerial vehicle body 1, a plurality of propellers 11 rotatably arranged on the top of the unmanned aerial vehicle body 1, and a protective mechanism installed on the unmanned aerial vehicle body 1 and used to protect the propellers 11. The unmanned aerial vehicle body 1 can fly through the propellers 11. The unmanned aerial vehicle body 1 and the propellers 11 constitute an existing unmanned aerial vehicle used for geological surveys and aerial photography. Its internal structure and principle have been disclosed and will not be elaborated on here.

[0023] Reference Figure 1-2 The protection mechanism includes an inner arc protection frame 2 and an outer arc protection frame 21 arranged on the outside of the drone body 1 for protecting the propeller 11 from the inside to the outside, and a plurality of first springs 22 and a plurality of second rubber blocks 23 fixed between the inner arc protection frame 2 and the outer arc protection frame 21. The first springs 22 and the second rubber blocks 23 can elastically connect the inner arc protection frame 2 and the outer arc protection frame 21, and the second rubber blocks 23 on the inner arc protection frame 2 can support the outer arc protection frame 21, so as to avoid the outer arc protection frame 21 sagging due to the high elasticity of the first springs 22 when the outer arc protection frame 21 is supported only by the first springs 22.

[0024] Reference Figure 1-2 The inner arc protective frame 2 is located between the propeller 11 and the outer arc protective frame 21. The propeller 11, the inner arc protective frame 2 and the outer arc protective frame 21 are flush. The inner arc protective frame 2 can separate the propeller 11 from the outer arc protective frame 21. When the outer arc protective frame 21 is broken due to excessive force, the inner arc protective frame 2 will block the broken fragments, making it difficult for the fragments to hit the propeller 11, thereby protecting the propeller 11. The flush inner arc protective frame 2 and the outer arc protective frame 21 can provide multiple protections for the internal propeller 11.

[0025] Reference Figure 1 and Figure 3 An adjustment mechanism for controlling the distance between the propeller 11 and the protective mechanism is provided on the outside of the drone body 1. The adjustment mechanism includes a plurality of fixed sleeve rods 3 fixedly arranged at the bottom of the outer side of the drone body 1, and a movable rod 31 fixedly arranged at the bottom of the inner arc-shaped protective frame 2. One end of the movable rod 31 is slidably arranged in the fixed sleeve rod 3. A slide groove 32 is provided in the fixed sleeve rod 3. One end of the movable rod 31 is slidably connected to the slide groove 32 of the fixed sleeve rod 3. The fixed sleeve rod 3 can connect and limit the movable rod 31 through the slide groove 32. People can adjust the position of the movable rod 31 in the fixed sleeve rod 3 by moving the movable rod 31, so as to adjust the position of the protective mechanism and control the distance between the propeller 11 and the protective mechanism, so that the protective mechanism after position adjustment can protect propellers 11 of different lengths.

[0026] Reference Figure 1 and Figure 3 A second spring 33 is fixed to the outer wall of one end of the fixed sleeve rod 3, a lifting plate 34 is fixed to one end of the second spring 33, a fixing rod 35 is fixed to the side of the lifting plate 34 close to the second spring 33, a plurality of positioning holes 36 are opened in the movable rod 31, one end of the fixing rod 35 passes through the fixed sleeve rod 3 and is inserted into the positioning hole 36. Under the pulling force of the second spring 33, the lifting plate 34 and the fixing rod 35 will move toward the side of the fixed sleeve rod 3, so that one end of the fixing rod 35 will be inserted into the corresponding positioning hole 36 to fix the movable rod 31 and the fixed sleeve rod 3 after the movement, and fix the position of the protective mechanism after adjustment.

[0027] Reference Figure 1 and Figure 3 A counterweight block 37 is fixedly provided on one side of the fixed sleeve rod 3 away from the second spring 33. The counterweight block 37 can roughly balance the weight on both sides of the fixed sleeve rod 3 to prevent the second spring 33 side of the fixed sleeve rod 3 from being too heavy, resulting in uneven weight distribution on the fixed sleeve rod 3 and making the drone unstable in flight.

[0028] The implementation principle of a protective structure for a geological survey drone in an embodiment of the utility model is as follows:

[0029] When in use, the protection mechanism composed of the inner arc-shaped protection frame 2, the first spring 22 and the outer arc-shaped protection frame 21 can provide multiple protections for the propeller 11, so that the propeller 11 will not directly contact obstacles during a collision. The first spring 22 and the rubber block 23 can buffer the drone body 1 during a collision, so that the drone body 1 is not easily damaged after a collision. When the outer arc-shaped protection frame 21 is broken due to excessive force after a collision, the inner arc-shaped protection frame 2 will block the broken fragments, so that the fragments are not easy to hit the propeller 11, thereby further protecting the propeller 11.

[0030] When people need to adjust the position of the protection mechanism, they can first pull the lifting plate 34 to the side away from the fixed sleeve rod 3 to make the fixed rod 35 disengage from the positioning hole 36, and then move the movable rod 31 to adjust the position of the movable rod 31 in the fixed sleeve rod 3, thereby adjusting the position of the protection mechanism, so that the protection mechanism after position adjustment can protect propellers 11 of different lengths.

[0031] Then release the lifting plate 34. At this time, under the pulling force of the second spring 33, the lifting plate 34 and the fixing rod 35 will move toward the side of the fixing sleeve rod 3, so that one end of the fixing rod 35 will be inserted into the corresponding positioning hole 36 to fix the moved movable rod 31 and the fixing sleeve rod 3, and fix the position of the protective mechanism after adjustment.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
