Description

Technical Field

[0001] The invention relates to the technical field of tree branch pruning near high-voltage electric wires, and in particular to a tree branch cutting device near high-voltage electric wires. Background Art

[0002] With the development of science and technology, the number of factories in various industries is increasing day by day. The development of factories is inseparable from the normal operation of electricity, and most of them require high voltage electricity. In order to ensure that the environment near the factory is not affected, trees are usually planted near the factory. However, as the trees grow, the branches may scratch the high-voltage wires, and the gum produced on the branches will also corrode the high-voltage wires, which will not only shorten the service life of the high-voltage wires, but also may cause power outages and economic losses.

[0003] In order to facilitate the pruning of branches, the existing technology usually adopts the method of installing a cutting mechanism at the bottom of the drone, and remotely controlling the drone to cut or prune the branches at high places. However, during the cutting process, the blade is easy to get stuck on the branches or leaves and is not easy to fall off, which makes the drone unable to fly back and may even damage the high-voltage line. In addition, since the branches are high and close to the high-voltage line, manual pruning is not only inconvenient but also very dangerous. When using drones for cutting, the blade cannot be discarded separately when it is stuck.

[0004] Therefore, there is an urgent need for a branch cutting device near a high-voltage line to solve the problem that the blade cannot be discarded alone when the blade is stuck. Summary of the invention

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] In order to facilitate the trimming of branches near high-voltage wires, a branch cutting device near high-voltage wires is provided in this embodiment. Figure 1-Figure 8 As shown, the cutting device includes a drone 10, a connecting member 20 and a cutting unit. One section of the connecting member 20 is pivotally connected to the bottom end of the drone 10; the cutting unit is arranged at the other end of the connecting member 20; the cutting unit includes a plurality of cutting mechanisms 30, the cutting mechanism 30 includes a first driving member 31, a second driving member 32, a movable member 33 and a saw blade 34, the first driving member 31 is arranged at the bottom of the saw blade 34, and its output end is transmission-connected with the saw blade 34 to drive the saw blade 34 to rotate, the movable member 33 is arranged above the saw blade 34, and the telescopic end of the second driving member 32 is used to drive the movable member 33 to move in the vertical direction, so that the movable member 33 can be separated from the saw blade 34 from the top.

[0046] In this device, the drone 10 can drive the cutting unit to fly upward to the cutting position through the connecting member 20, thereby avoiding the operator from climbing to the top of the tree for pruning and avoiding the operator from getting close to the high-voltage line, ensuring the convenience while also ensuring the safety of the operator. The cutting unit includes a plurality of cutting mechanisms 30, which ensures the overall cutting efficiency. The connecting member 20 is pivotally connected to the bottom of the drone 10, which can improve the flexibility of cutting. The output end of the first driving member 31 is connected to the saw blade 34, which can smoothly drive the saw blade 34 to rotate, thereby completing the cutting work; during the cutting process, the telescopic end of the second driving member 32 extends, and the saw blade 34 is fixed in the rotating position through the movable member 33. When the saw blade 34 is stuck, the telescopic end of the second driving member 32 can drive the movable member 33 to retract, so that the movable member 33 no longer limits the top of the saw blade 34. Then, by controlling the drone 10, the drone 10 drives the cutting unit to shake, so that the saw blade 34 can fall off the cutting unit, and the stuck saw blade 34 can be easily discarded, ensuring the safety of operation.

[0047] It should be noted here that, in this embodiment, Figure 3-Figure 7As shown, the cutting mechanism 30 further includes a housing 35, and the first driving member 31, the second driving member 32 and the movable member 33 are all arranged in the housing 35. This arrangement improves the integrity of the device, so that it is convenient to set it on the mounting frame 40. Specifically, the housing 35 includes an upper box body 352 and a lower box body 353, wherein the first driving member 31 is arranged in the lower box body 353, and the second driving member 32 is arranged in the upper box body 352. In addition, the cutting mechanism 30 further includes a second elastic member 36 and a sleeve 37, wherein one end of the second elastic member 36 is connected to the upper box body 352, and the other end is connected to the movable member 33, and the bottom end of the movable member 33 is connected to the sleeve 37, and the output end of the first driving member 31 passes through the mounting hole 341 of the saw blade 34. After the installation is completed, the sleeve 37 is sleeved on the part of the output end passing through the mounting hole 341. When the second elastic member 36 is not subjected to external force, the second elastic member 36 can push the movable member 33 and the sleeve 37 downward, thereby limiting the saw blade 34 from the upper part of the output end, thereby ensuring that the saw blade 34 can rotate at the preset position. When the saw blade 34 needs to be abandoned, the second driving member 32 drives the movable member 33 and the sleeve 37 to rise and compress the second elastic member 36, thereby causing the movable member 33 and the sleeve 37 to separate from the top of the saw blade 34, thereby no longer limiting the saw blade 34 from the top of the saw blade 34, and then by operating and shaking the drone 10, the saw blade 34 can be thrown out from the gap at the top, thereby achieving the purpose of abandoning the saw blade 34.

[0048] It is further explained that the first driving member 31 is a rotating shaft stepper motor, whose output end can drive the saw blade 34 to rotate around its own axis; the second driving member 32 is an electric cylinder (electric linear actuator). Both the rotating shaft stepper motor and the electric cylinder have the advantages of simple structure, high precision, fast response and high stability.

[0049] To facilitate the installation of the cutting mechanism 30, Figure 1-Figure 3 As shown, the cutting unit further includes a mounting frame 40, and a plurality of cutting mechanisms 30 are spaced and evenly arranged in the mounting frame 40 along the length direction of the mounting frame 40. This structure enables the plurality of cutting mechanisms 30 to be installed in parallel and in parallel, thereby simplifying the overall structure and improving the installation efficiency, and further improving the cutting efficiency.

[0050] like Figure 1-Figure 3 As shown, the mounting frame 40 is provided with a cutting hole 41 along its width direction, and the saw blade 34 is arranged in the cutting hole 41. When the saw blade 34 is stuck and needs to be abandoned in time, the second driving member 32 drives the movable member 33 to rise, thereby ensuring that the top of the saw blade 34 is no longer restricted. Since the cutting hole 41 runs through the mounting frame 40, it is ensured that when the drone 10 is shaken at this time, the saw blade 34 can fall off from both sides, thereby making the discarding process of the saw blade 34 more convenient. It should be noted here that, if Figure 4-Figure 8As shown, there is a gap between the upper box body 352 and the lower box body 353, and the saw blade 34 can just pass through the gap and extend from the cutting hole 41, which is also convenient for installation.

[0051] In addition, the plurality of cutting mechanisms 30 and the mounting frame 40 are all detachably connected. The detachable connection mode is not only convenient for installation, but also conducive to subsequent maintenance and replacement of parts, which can improve the overall convenience of use.

[0052] Due to the complex growth of branches near high-voltage wires, the saw blade 34 may not be discarded, which may cause the device to get stuck in the bushes. Figure 4-Figure 8 As shown, a connecting assembly 50 is provided on the mounting frame 40, and the connecting assembly 50 includes a connecting block 51 and a sliding member 52. A sliding groove 511 is provided inside the connecting block 51, and the sliding member 52 can slide in the sliding groove 511. A first rack 521 is provided at one end of the sliding member 52; a vertical rod 60 is provided on one side of the cutting mechanism 30, one end of the vertical rod 60 is connected to the mounting frame 40, and a gear 61 is provided at the other end. A second rack 331 is provided on the side of the movable member 33 close to the vertical rod 60, and the gear 61 is meshed and connected with the first rack 521 and the second rack 331 at the same time, and the first rack 521 is perpendicular to the second rack 331.

[0053] In the above structure, when the saw blade 34 cannot be discarded smoothly, the movable member 33 can be continuously driven upward by the second driving member 32, and the movable member 33 can drive the gear 61 to rotate through the second rack 331, and the gear 61 can continue to drive the first rack 521 to move in the direction away from the connecting block 51, that is, the second rack 331 can move upward while the sliding member 52 can be pulled out from the inside of the connecting block 51. When the sliding member 52 is completely pulled out from the inside of the connecting block 51, the cutting mechanism 30 is disengaged from the connecting assembly 50, and the entire cutting mechanism 30 can be abandoned to ensure that the device will not be stuck between the tree branches and the high-voltage wires.

[0054] What needs to be explained here is that Fig. 9 As shown, the second rack 331 is meshed with the inner side of the gear 61, the outer side of the gear 61 protrudes from the second rack 331, and the first rack 521 can be meshed with the outer side (the protruding side) of the gear 61, which effectively reduces the difficulty of installation. In addition, a plug rod 62 is also provided on the vertical rod 60, and the plug rod 62 is arranged opposite to the sliding member 52. The sliding member 52 is provided with a plug hole along the axial direction. When the gear 61 drives the sliding member 52 to move in a direction away from the connecting block 51, the plug rod 62 can be correspondingly plugged into the plug hole, thereby ensuring the stability of the sliding member 52 during the movement.

[0055] However, the cutting mechanism 30 cannot be firmly fixed by the sliding member 52 alone. Figure 4-Figure 8As shown, a fixing portion 351 is provided on one side of the housing 35 along the width direction, and the connecting assembly 50 further includes a latch 54, which is configured to be plugged into the fixing portion 351, or retracted into the connecting block 51, so as to separate the cutting mechanism 30 from the connecting assembly 50. By providing the latch 54, when cutting work is required, the latch 54 is controlled to be plugged into the fixing portion 351 to fix the cutting mechanism 30; when the entire cutting mechanism 30 needs to be abandoned, the latch 54 is retracted into the connecting block 51, so that the cutting mechanism 30 can be separated from the connecting assembly 50 and then fall off. Not only can a good fixing effect be produced, but also the cutting mechanism 30 can be dropped off in time.

[0056] To simplify the structure of the insertion and retraction of the latch 54, as shown in FIG. Figure 4-Figure 8 As shown, the connecting assembly 50 also includes a movable rod 53 and a first elastic member 55. The first elastic member 55 is arranged inside the connecting block 51 along the vertical direction, and its two ends are respectively connected to the latch 54 and the movable rod 53. The other end of the movable rod 53 can abut against the sliding member 52. The elastic force of the first elastic member 55 can make the latch 54 shrink toward the inside of the connecting block 51. When the sliding member 52 is inserted into the sliding groove 511, the other end of the latch 54 can be inserted into the fixing portion 351. Driven by the gear 61, the sliding member 52 can slide in the sliding groove 511. When the movable rod 53 no longer abuts the sliding member 52, the first elastic member 55 is no longer subjected to external force and can pull the latch 54 inward, so that the latch 54 is no longer connected to the fixing portion 351, and the cutting mechanism 30 can fall off; when the cutting mechanism 30 needs to be fixed, the sliding member 52 only needs to be inserted back into the sliding groove 511, and the movable rod 53 abuts against the sliding member 52. At this time, the movable rod 53 can compress the first elastic member 55, and then push the latch 54 to extend out of the connecting block 51 through the first elastic member 55, and plug it into the fixing portion 351, thereby completing the fixing of the cutting mechanism 30. The structure is simple, and only the second driving member 32 needs to be controlled to successively complete the discarding of the saw blade 34 and the cutting mechanism 30, ensuring a good use effect. The first elastic member 55 is a spring, which has a simple structure, is low in price and easy to install, and can effectively reduce costs.

[0057] To facilitate the insertion of the sliding member 52 back into the sliding groove 511, Figure 4-Figure 8 As shown, an end of the movable rod 53 away from the first elastic member 55 is provided with an arc surface 531. When the sliding member 52 moves toward the inside of the connecting block 51, its end can abut against the arc surface 531, and at this time, the movable rod 53 can be separated in the horizontal and vertical directions. The horizontal component force is offset by the inner wall of the connecting block 51, and the vertical component force can compress the first elastic member 55, so that the latch 54 can be pushed toward the outside of the connecting block 51, thereby achieving fixed connection of the cutting mechanism 30. The structure is simple and easy to use.

[0058] In order to ensure a good fixing effect and the effect of being able to be discarded in time, each cutting mechanism 30 is provided with a second rack 331, a connecting assembly 50 and a vertical rod 60 on both sides along the length direction. Not only can a good fixing effect be ensured and a stable cutting environment be formed, but also the cutting mechanism 30 can be discarded conveniently, so as to avoid the inconvenience of the drone 10 flying back after the saw blade 34 is stuck, thereby avoiding damage to the high-voltage line.

[0059] In addition, if Figure 1-Figure 3 As shown, a positioning hole 42 is provided on the mounting frame 40, and a positioning pin 21 is provided at one end of the connector 20 away from the drone 10, and the positioning pin 21 can be correspondingly inserted into the positioning hole 42. The method of inserting the positioning pin 21 into the positioning hole 42 is not only convenient for installing the cutting unit, but also convenient for subsequent maintenance and replacement of the drone 10, ensuring ease of use.

[0060] In addition, it is obvious that the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
