Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) tree repair, and particularly to a UAV tree repair sawing device. Background Art

[0002] With the development of technology, UAVs are widely used in fields such as express delivery and high-altitude operations. When pruning redundant branches of trees, the pruning of tall trees can be achieved by using a UAV. Such a device mainly prunes branches at higher positions by installing a sawing device on the UAV.

[0003] However, during the use of the sawing component installed on the UAV, since the bracket supporting the bottom of the UAV will come into contact with the ground when the UAV lands, the sawing component will collide with the ground. When there are hard objects on the ground, the saw blade may be damaged; the sawing component is directly fixed to the bottom end of the UAV, making it inconvenient to operate when performing internal maintenance or replacing the saw blade, which is not conducive to improving its usage effect; in addition, since the installation position of the saw blade is the same, when the UAV flies around the tree, only the branches on the side can be pruned. When it is necessary to saw the branches at the top of the tree, it is inconvenient to control the flight angle of the UAV, so that the position of the saw blade cannot be adjusted flexibly, resulting in poor pruning effect of the branches at the top of the tree.

[0009] Specifically, the second sawing mechanism includes a second rotating shaft and a second motor. The second motor is fixedly installed in the support frame. The output end of the second motor is fixedly connected to a second rotating shaft through a coupling. Another two second rotating shafts are rotatably connected in the base.

The second motor is located on the inner wall of the support frame close to the base, and one of the second rotating shafts is rotatably connected to the support frame.

[0010] The beneficial effects of the present invention are:

[0011] (1) For a drone tree repair sawing device according to the present invention, the support mechanism is fixed to the bottom end of the drone. Through the limiting mechanism, it is convenient for the operator to disassemble and assemble the support mechanism. That is, the operator can first place the clamping rod into the interior of the mounting seat. When the top end of the clamping rod abuts against the rubber pad provided inside the mounting seat, the second hydraulic rod can be activated. The telescopic end of the second hydraulic rod is fixedly connected with a resisting block. When the resisting block slides along the inner wall of the mounting seat, the resisting block can abut against the roller. Since the roller is rotatably connected to the rotating rod, when the roller is subjected to the abutting force of the resisting block, the rotating rod can drive the coupling shaft to rotate. The coupling shaft rotates along the inner wall of the mounting seat, causing the torsion spring sleeved on the coupling shaft to deform. And the end of the rotating rod close to the torsion spring is arranged in an arc surface structure. When the end of the rotating rod rotates to the position of the limiting groove provided inside the mounting seat, the end of the rotating rod can abut against the gasket, thereby facilitating the clamping rod to be abutted into the interior of the mounting seat through the rotating rod, and thus the clamping rod can be limited by the rotating rod. After the clamping rod is fixed inside the mounting seat, a tool can be used to fix the mounting seat to the bottom end of the drone. By controlling the component to start the drone, the drone can fly into the air, causing the mounting seat to drive the clamping rod to displace. A support plate is fixed to the end of the clamping rod, and the support plate drives the support frame rotating inside the mounting frame to move. Since the support frame is arranged in an arc surface structure, when the drone moves upward, the support frame rotates along the fixed rod fixed inside the mounting frame, so that the base fixed on the support frame is in a vertical state, thereby adjusting the placement angle of the support frame.

[0012] (2) For a drone tree repair sawing device according to the present invention, when the drone flies into the air, it can drive the support mechanism to rotate, so that the base is in a vertical state, thereby facilitating the trimming of redundant branches by the second sawing mechanism. That is, when the drone moves around the tree, the operator can turn on the control switch of the second motor. The second motor is installed inside the support frame close to the base. When it is started, it can drive a second rotating shaft to rotate inside the support frame. The other two second rotating shafts are installed inside the base. Since gears are fixedly connected to the second rotating shafts, when one second rotating shaft drives the gear to rotate inside the base, the chain meshing with the gear can drive the other two gears to rotate. The other two gears drive the other two second rotating shafts to rotate. Thus, the second saw blades fixed to the ends of the second rotating shafts can trim the redundant branches during rotation, thereby facilitating the reduction of the labor intensity of the operator.

[0013] (3) The drone tree repair and sawing device described in the present invention can start the first sawing mechanism to slide in the fixed plate, thereby causing the first sawing mechanism to rotate ninety degrees, so that the first sawing mechanism can be used to trim the branches on the tree top. That is, when it is necessary to trim the branches on the tree top, the operator can first start the first hydraulic rod. A slide plate is fixed to the telescopic end of the first hydraulic rod. The first hydraulic rod drives the slide plate to slide in a direction close to the first hydraulic rod, so that the stop rod fixed on the slide plate can slide in the slide groove provided in the rotating plate and the clamping groove provided in the fixed plate, thereby the stop rod can slide in the sliding groove provided in the rotating plate and the clamping groove provided in the fixed plate. When the rod slides, it contacts the inner wall of the rotating plate, so that the rotating plate drives the connecting rod fixed thereto to rotate. When the connecting rod rotates inside the fixed plate and the base, it can drive the rotating block fixed on the connecting rod to rotate. When the rotating block rotates in the through groove provided in the base, the rotating block can drive the first rotating shaft and the first saw blade to rotate ninety degrees. At this time, the control switch of the first motor installed in the rotating block is turned on. When the first motor starts, it can drive the first rotating shaft to rotate along the rotating block, and then the first rotating shaft drives the first saw blade to rotate to trim the branches on the top of the tree.

Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] As shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 10 shown, a kind of unmanned aerial vehicle tree repair sawing device of the present invention includes an unmanned aerial vehicle 1, and a support mechanism 2 is fixedly installed on the unmanned aerial vehicle 1; a limiting mechanism 7 is installed on the support mechanism 2; a base 3 is fixed at the end of the support mechanism 2; a fixing plate 6 is fixedly connected to the base 3; a first sawing mechanism 4 is installed on the fixing plate 6; a second sawing mechanism 5 is rotatably arranged on the base 3;

[0029] Specifically, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 10 and Figure 11As shown in the figure, the first sawing mechanism 4 includes a sliding plate 406 and a first hydraulic rod 407. The first hydraulic rod 407 is fixedly installed on the fixed plate 6. The telescopic end of the first hydraulic rod 407 is fixedly connected to the sliding plate 406. A resisting rod 408 is fixedly installed on the sliding plate 406. A rotating plate 411 abuts against the resisting rod 408. A chute 409 is provided on the rotating plate 411. A clamping groove 410 is provided on the fixed plate 6. The resisting rod 408 slides at the positions of the chute 409 and the clamping groove 410. A connecting rod 412 is fixedly installed on the rotating plate 411. The connecting rod 412 is rotatably connected to the fixed plate 6. A rotating block 403 is fixedly installed on the connecting rod 412. A through groove 405 is provided at a position of the base 3 close to the rotating block 403. A first motor 404 is fixedly installed in the rotating block 403. The output end of the first motor 404 is fixedly connected to a first rotating shaft 402 through a coupling. A first saw blade 401 is fixedly connected to the first rotating shaft 402. The sliding plate 406 is slidably connected to the fixed plate 6. The resisting rod 408 is slidably connected to the rotating plate 411 and the fixed plate 6. Both the connecting rod 412 and the rotating block 403 are rotatably connected to the base 3. The rotating block 403 is rotatably installed at the position of the through groove 405. The first rotating shaft 402 is rotatably connected to the rotating block 403. By starting the first sawing mechanism 4, it can slide in the fixed plate 6, and then the first sawing mechanism 4 rotates by 90 degrees, so as to facilitate the first sawing mechanism 4 to trim the branches at the top of the tree. That is, when it is necessary to trim the branches at the top of the tree, the operator can first start the first hydraulic rod 407. The telescopic end of the first hydraulic rod 407 is fixed with the sliding plate 406. The first hydraulic rod 407 drives the sliding plate 406 to slide in the direction close to the first hydraulic rod 407, which can make the resisting rod 408 fixed on the sliding plate 406 slide at the positions of the chute 409 provided in the rotating plate 411 and the clamping groove 410 provided in the fixed plate 6. When the resisting rod 408 slides, it abuts against the inner wall of the rotating plate 411, and then the rotating plate 411 drives the connecting rod 412 fixed to it to rotate. When the connecting rod 412 rotates inside the fixed plate 6 and the base 3, it can drive the rotating block 403 fixed on the connecting rod 412 to rotate. When the rotating block 403 rotates at the position of the through groove 405 provided in the base 3, it can make the rotating block 403 drive the first rotating shaft 402 and the first saw blade 401 to rotate by 90 degrees. At this time, the control switch of the first motor 404 installed in the rotating block 403 is turned on. When the first motor 404 is started, it can drive the first rotating shaft 402 to rotate along with the rotating block 403. Then, when the first rotating shaft 402 drives the first saw blade 401 to rotate, the branches at the top of the tree can be trimmed.

[0030] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、Figure 6 , Figure 8 and Figure 9 As shown, the supporting mechanism 2 includes a clamping rod 205 and a mounting seat 206, the mounting seat 206 is fixedly connected to the UAV 1, the mounting seat 206 is clamped with the clamping rod 205, the clamping rod 205 is fixedly connected to the support plate 204, the support plate 204 is fixedly connected to the mounting frame 203, the mounting frame 203 is fixedly connected to the fixing rod 202, the fixing rod 202 is rotatably connected to the supporting frame 201, the end of the supporting frame 201 away from the mounting frame 203 is arranged in an arc structure, and the base 3 is fixedly connected to the supporting frame 201.

[0031] Specifically, Figure 8 and Figure 9As shown, the limiting mechanism 7 includes a second hydraulic rod 701 and a resisting block 702. Two second hydraulic rods 701 are symmetrically and fixedly installed inside the mounting base 206. The telescopic end of the second hydraulic rod 701 is fixedly connected to a resisting block 702. A roller 703 abuts against the resisting block 702. The roller 703 is rotatably connected to a rotating rod 706. A coupling shaft 707 is fixedly installed on the rotating rod 706. A torsion spring 708 is sleeved on the coupling shaft 707. The torsion spring 708 is fixedly connected between the rotating rod 706 and the mounting base 206. A limiting groove 705 is provided on the clamping rod 205. A gasket 704 is adhered to the clamping rod 205. The end of the rotating rod 706 abuts against the gasket 704. The resisting block 702 is arranged in an inclined plane structure. The roller 703 is in rolling connection with the resisting block 702. The coupling shaft 707 is rotatably connected to the mounting base 206. The two limiting grooves 705 are symmetrically arranged on both sides of the clamping rod 205. The gasket 704 is located on the inner wall of the clamping rod 205 close to the limiting groove 705. The end of the rotating rod 706 in contact with the gasket 704 is arranged in an arc surface structure. Fix the support mechanism 2 at the bottom of the drone 1. Through the limiting mechanism 7, it is convenient for the operator to disassemble and assemble the support mechanism 2, that is: the operator can first place the clamping rod 205 into the inside of the mounting base 206. When the top of the clamping rod 205 abuts against the rubber pad provided inside the mounting base 206, the second hydraulic rod 701 can be started. The telescopic end of the second hydraulic rod 701 is fixedly connected to a resisting block 702. When the resisting block 702 slides along the inner wall of the mounting base 206, the resisting block 702 can abut against the roller 703. Since the roller 703 is rotatably connected to the rotating rod 706, when the roller 703 is subjected to the abutting force of the resisting block 702, the rotating rod 706 can drive the coupling shaft 707 to rotate. The coupling shaft 707 rotates along the inner wall of the mounting base 206, causing the torsion spring 708 sleeved on the coupling shaft 707 to deform. And one end of the rotating rod 706 close to the torsion spring 708 is arranged in an arc surface structure. When the end of the rotating rod 706 rotates to the position of the limiting groove 705 provided inside the mounting base 206, the end of the rotating rod 706 can abut against the gasket 704, thereby facilitating the clamping rod 205 to be abutted into the inside of the mounting base 206 through the rotating rod 706, and thus the clamping rod 205 can be limited by the rotating rod 706; after the clamping rod 205 is fixed inside the mounting base 206, a tool can be used to fix the mounting base 206 to the bottom of the drone 1. By starting the drone 1 through the control component, the drone 1 can fly into the air, causing the mounting base 206 to drive the clamping rod 205 to displace. A support plate 204 is fixed at the end of the clamping rod 205, and the support plate 204 drives the support frame 201 rotating inside the mounting frame 203 to move. Since the support frame 201 is arranged in an arc surface structure, when the drone 1 moves upward, the support frame 201 rotates along the fixed rod 202 fixed inside the mounting frame 203, and thus the base 3 fixed on the support frame 201 is in a vertical state, thereby adjusting the placement angle of the support frame 201.

[0032] Specifically, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the second sawing mechanism 5 includes a second rotating shaft 502 and a second motor 505. The second motor 505 is fixedly installed inside the support frame 201. The output end of the second motor 505 is fixedly connected to a second rotating shaft 502 through a coupling. Another two second rotating shafts 502 are rotatably connected inside the base 3. A second saw blade 501 and a gear 503 are fixedly installed on each of the plurality of second rotating shafts 502. A chain 504 is engaged with the gear 503. The second motor 505 is located on the inner wall of the support frame 201 close to the base 3, and one of the second rotating shafts 502 is rotatably connected to the support frame 201. When the drone 1 flies into the air, it can drive the support mechanism 2 to rotate, so that the base 3 is in a vertical state, facilitating the trimming of redundant branches by the second sawing mechanism 5. That is, when the drone 1 moves around the tree, the operator can turn on the control switch of the second motor 505. The second motor 505 is installed inside the support frame 201 close to the base 3. When it starts, it can drive a second rotating shaft 502 to rotate inside the support frame 201. The other two second rotating shafts 502 are installed inside the base 3. Since the gear 503 is fixedly connected to the second rotating shaft 502, when one second rotating shaft 502 drives the gear 503 to rotate inside the base 3, the chain 504 engaged with the gear 503 can drive the other two gears 503 to rotate. The other two gears 503 drive the other two second rotating shafts 502 to rotate, so that the second saw blade 501 fixed to the end of the second rotating shaft 502 can trim the redundant branches during rotation, facilitating the reduction of the labor intensity of the operator.

[0033] When the present invention is in use, first, the operator can first place the clamping rod 205 into the interior of the mounting seat 206. When the top end of the clamping rod 205 abuts against the rubber pad provided inside the mounting seat 206, the second hydraulic rod 701 can be activated. The telescopic end of the second hydraulic rod 701 is fixedly connected with a blocking block 702. When the blocking block 702 slides along the inner wall of the mounting seat 206, the blocking block 702 can abut against the roller 703. Since the roller 703 is rotatably connected to the rotating rod 706, when the roller 703 receives the abutting force of the blocking block 702, the rotating rod 706 can drive the coupling shaft 707 to rotate. The coupling shaft 707 rotates along the inner wall of the mounting seat 206, causing the torsion spring 708 sleeved on the coupling shaft 707 to deform. Moreover, one end of the rotating rod 706 close to the torsion spring 708 is arranged in an arc structure. When the end of the rotating rod 706 rotates to the position of the limiting groove 705 provided inside the mounting seat 206, the end of the rotating rod 706 can abut against the gasket 704, thereby facilitating the clamping rod 205 to be abutted into the interior of the mounting seat 206 through the rotating rod 706, and thus the clamping rod 205 can be limited by the rotating rod 706; after the clamping rod 205 is fixed inside the mounting seat 206, a tool can be used to fix the mounting seat 206 to the bottom end of the drone 1. By activating the drone 1 through the control component, the drone 1 can fly into the air, causing the mounting seat 206 to drive the clamping rod 205 to displace. A support plate 204 is fixed to the end of the clamping rod 205, and the support plate 204 drives the support frame 201 rotating inside the mounting frame 203 to move. Since the support frame 201 is arranged in an arc structure, when the drone 1 moves upward, the support frame 201 rotates along the fixed rod 202 fixed inside the mounting frame 203, and thus the base 3 fixed to the support frame 201 is in a vertical state, thereby adjusting the placement angle of the support frame 201;

[0034] When the drone 1 moves around the trees, the operator can turn on the control switch of the second motor 505. The second motor 505 is installed inside the support frame 201 close to the base 3. When it is activated, it can drive a second rotating shaft 502 to rotate inside the support frame 201. The other two second rotating shafts 502 are installed inside the base 3. Since a gear 503 is fixedly connected to the second rotating shaft 502, when one second rotating shaft 502 drives the gear 503 to rotate inside the base 3, the chain 504 engaged with the gear 503 can drive the other two gears 503 to rotate. The other two gears 503 drive the other two second rotating shafts 502 to rotate. Thus, the second saw blades 501 fixed to the ends of the second rotating shafts 502 can trim the redundant branches during rotation, thereby facilitating the reduction of the labor intensity of the operator;

[0035] When it is necessary to trim the branches on the top of the tree, the operator can first start the first hydraulic rod 407. A slide plate 406 is fixed to the telescopic end of the first hydraulic rod 407. The first hydraulic rod 407 drives the slide plate 406 to slide in the direction close to the first hydraulic rod 407, so that the stopper 408 fixed on the slide plate 406 can slide in the slide groove 409 provided in the rotating plate 411 and the card groove 410 provided in the fixed plate 6. When the stopper 408 slides, it contacts the inner wall of the rotating plate 411, so that the rotating plate 411 drives the connecting rod 412 fixed thereto to rotate. When the connecting rod 412 is fixed in the fixed plate 6, the connecting rod 412 is rotated. When the fixed plate 6 and the base 3 rotate internally, the rotating block 403 fixed on the connecting rod 412 can be driven to rotate. When the rotating block 403 rotates in the through slot 405 provided in the base 3, the rotating block 403 can drive the first rotating shaft 402 and the first saw blade 401 to rotate ninety degrees. At this time, the control switch of the first motor 404 installed in the rotating block 403 is turned on. When the first motor 404 is started, it can drive the first rotating shaft 402 to rotate along the rotating block 403, and then the first rotating shaft 402 drives the first saw blade 401 to rotate, so that the branches on the top of the tree can be trimmed.
