Description

Technical Field

[0001] The utility model belongs to the field of power distribution line maintenance, in particular to a device for pruning trees at high places. Background Art

[0002] Due to power distribution needs, oilfield development often involves the construction of numerous 6kV or 10kV distribution lines. Some of these distribution line corridors overlap closely with tree corridors. If trees grow too tall and densely near high-voltage conductors, they can disrupt the distribution lines, causing ground faults, short circuits, and line breaks. To address this issue, high-altitude tree pruning is necessary.

[0003] The utility model patent, publication number CN207399949U, discloses a pair of aerial shears for flower planting and pruning. The shears comprise a telescopic rod, a fixed frame secured above the telescopic rod, and a movable frame hingedly mounted on the fixed frame. A third pulley is hingedly mounted on the movable frame, a second pulley is mounted on the fixed frame, and a first pulley is mounted at the bottom of the telescopic rod. The first, second, and third pulleys are connected by a pull rope. The telescopic rod is also provided with a crank for driving the first pulley to rotate. During use, the crank is used to crank the first pulley, which drives the second and third pulleys to rotate. The third pulley descends during rotation, thereby driving one end of the movable frame downward. The movable frame then drives the cutter blade to cut branches and leaves.

[0004] However, the above patent has the following problems: First, it relies solely on a cutter to cut leaves, but the cutting capacity of the cutter is limited and cannot effectively cut all trees; second, it requires frequent shaking of the handle to achieve pruning, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to solve the above deficiencies in the prior art, the present invention aims to provide a device for pruning trees at heights, so as to achieve the purpose of thoroughly pruning trees near high-voltage wires in a time-saving and labor-saving manner.

[0006] In order to achieve the above purpose, the technical solutions adopted by the present utility model are as follows:

[0007] A device for pruning high trees comprises a rod, a driving device disposed at the top of the rod, a fixed blade fixed to the driving device, and a movable blade rotatably disposed on the driving device; the end of the movable blade facing the fixed blade is a shearing surface, and the movable blade moves in a direction toward or away from the fixed blade;

[0008] The rod body is provided with a first Bluetooth module and a first switch electrically connected to the first Bluetooth module and used to control the first Bluetooth module to be turned on and off. The first Bluetooth module is electrically connected to the driving device.

[0009] It also includes a remote control component, which includes a shell, on which is provided a second Bluetooth module and a second switch electrically connected to the second Bluetooth module for controlling the opening and closing of the second Bluetooth module; the first Bluetooth module is communicatively connected with the second Bluetooth module; and an operation button is also provided on the shell.

[0010] As a limitation of the present invention: the top of the movable blade is provided with an arc-shaped hook extending toward the fixed blade, and the hook is used to abut against the top of the fixed blade.

[0011] As another limitation of the present invention: a link rod is detachably provided at the bottom of the rod body.

[0012] As a further limitation of the present invention: a first clamping claw and a second clamping claw are provided on the shell, and a clamping space for matching with the rod body or the link stick is formed between the first clamping claw and the second clamping claw.

[0013] As a further limitation of the present invention: the first clamping claw and the second clamping claw are both made of plastic.

[0014] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] The utility model includes a rod body, a drive device disposed at the top of the rod body, a fixed blade, and a movable blade. The rod body is provided with a first Bluetooth module, which is electrically connected to the drive device. The utility model also includes a remote control assembly, in which a second Bluetooth module is in communication with the first Bluetooth module, and the remote control assembly is provided with an operation button. When the operation button is pressed, the movable blade, driven by the drive device, moves toward the fixed blade to complete the cutting action. Compared with the existing technology that frequently shakes the handle, the utility model can achieve tree cutting more conveniently, saving time and effort.

[0016] The present invention uses a remote control assembly to control the drive mechanism, causing the movable blade to move closer to the fixed blade to cut the tree. If the tree is not cut, the lever can be dragged. Because the present invention uses a remote control assembly, the drive mechanism can provide sufficient driving force to clamp the tree between the fixed and movable blades, and only then will it be broken by dragging the lever. Conventional technology uses pulleys and pull ropes to drive the cutter, but the pull ropes do not provide sufficient support and can break when dragged.

[0017] In summary, the utility model can realize the trimming or dragging of trees, reduce the failure rate of the distribution line, and the method of trimming trees is more time-saving and labor-saving; the utility model is suitable for all scenarios where high trees need to be trimmed.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation to the present invention.

[0026] like Figures 1 to 5 As shown, this embodiment includes a rod body 1, a driving device 2 arranged at the top of the rod body 1, a fixed blade 3 fixed on the driving device 2, and a movable blade 4 rotatably arranged on the driving device 2; it also includes a remote control component 8, which uses wireless communication technology to control the operation of the driving device 2, thereby driving the movable blade 4 to rotate, so that trees can be pruned more labor-savingly.

[0027] like Figure 1-3As shown, a rotating shaft 20 is fixedly provided at the top of the driving device 2. In this embodiment, the driving device 2 includes a housing and a brushless motor, a reducer and a reduction gear located inside the housing. The housing is fixedly provided with a rotating shaft 20, the fixed blade 3 is fixedly connected to the rotating shaft 20, and the movable blade 4 is rotatably sleeved on the rotating shaft 20. The input end of the reducer is connected to the output end of the brushless motor, and the output end of the reducer is connected to the reduction gear, which is fixedly connected to the movable blade 4. When the brushless motor drives the reduction gear to rotate, the movable blade 4 moves in the direction close to the fixed blade 3 to achieve cutting. This structure refers to the structure of existing electric scissors, and the specific connection relationship is as follows. Figure 1-3 Not shown in the figure.

[0028] The main improvements of this embodiment are:

[0029] 1. Fixed blade 3, movable blade 4;

[0030] In this embodiment, both the fixed blade 3 and the movable blade 4 are arc-shaped structures, wherein the fixed blade 3 is concave toward the movable blade 4, and the movable blade 4 is convex toward the fixed blade 3. Since the end of the movable blade 4 facing the fixed blade 3 is the shearing surface 5, when in use, the tree is located between the fixed blade 3 and the movable blade 4, and when the movable blade 4 moves toward the fixed blade 3, cutting is completed.

[0031] In this embodiment, the top of the movable blade 4 is provided with an arc-shaped hook 13 extending toward the fixed blade 3. When the branch is located between the fixed blade 3 and the movable blade 4 and the movable blade 4 moves toward the fixed blade 3, the bottom edge of the hook 13 abuts against the top of the fixed blade 3. Figure 3 As shown, it is similar to the hugging action and can hold the branch tightly.

[0032] 2. Setting the link stick 18;

[0033] like Figure 1 、 2 As shown, in this embodiment, a link rod 18 is detachably provided at the bottom of the rod body 1. The structure of the link rod 18 is prior art and will not be described in detail in this embodiment. The purpose of providing the link rod 18 is to increase the length of the rod body 1. Because the existing extension method uses a telescopic rod, the maximum length of the telescopic rod can reach 2 meters. However, the height of the high-voltage wire is 7-10 meters, and the length of a link rod 18 section is 1.5 meters. By connecting multiple link rods 18 in series, this embodiment can be used to prune trees high above the high-voltage wire. In this embodiment, the bottom of the rod body 1 is configured as an external thread, which is threadedly connected to the link rod 18. Of course, any other detachable connection method known in the prior art can also be used. Figure 1 Only one link rod 18 is drawn for illustration. If two link rods are used, the second link rod can be threadedly connected to the bottom of the link rod 18.

[0034] 3. Remote control component 8;

[0035] This embodiment uses the remote control component 8 to achieve wireless control of tree pruning. Figure 4 、 5 As shown, the remote control component 8 includes a shell 9, on which a second Bluetooth module 10 and a second switch 11 are provided. The second switch 11 is electrically connected to the second Bluetooth module 10 and is used to control the opening and closing of the second Bluetooth module 10. The second Bluetooth module 10 adopts the existing technology, and the method of turning on the second Bluetooth module 10 by the second switch 11 is also the existing technology, which will not be described in detail here.

[0036] Correspondingly, such as Figure 1 As shown, the rod body 1 is provided with a first Bluetooth module 6 and a first switch 7 electrically connected to the first Bluetooth module 6 for controlling the opening and closing of the first Bluetooth module 6. The first Bluetooth module 6 also adopts the existing technology, and the method of turning on the first Bluetooth module 6 by the first switch 7 is also the existing technology, which will not be described in detail here.

[0037] like Figure 1 As shown, the first Bluetooth module 6 is electrically connected to the drive device 2, and the first Bluetooth module 6 is communicatively connected to the second Bluetooth module 10. An operating button 12 is also provided on the housing 9. The operating principle is: turn on the first switch 7 and the second switch 11 to pair the first Bluetooth module 6 and the second Bluetooth module 10. This pairing behavior is limited to the first use. After the first switch 7 and the second switch 11 are subsequently turned on, the first Bluetooth module 6 and the second Bluetooth module 10 will be automatically connected. Press the operating button 12, and use the wireless communication technology to make the movable blade 4 rotate clockwise around the rotating shaft 20 under the push of the drive device 2 until the cutting action is completed when the movable blade 4 and the fixed blade 3 are closed. Release the operating button 12, and the movable blade 4 moves in the direction away from the fixed blade 3 (i.e. counterclockwise) to achieve reset. As shown Figure 4 、 5 As shown, an antenna 19 is provided on the housing 9 for transmitting and receiving signals. The principle of the antenna 19 is prior art and will not be described in detail in this embodiment.

[0038] If the tree is too hard to be trimmed smoothly, the hook 13 on the movable blade 4 and the fixed blade 3 form an encircling action, and the tree is tightly held under the push of the drive device 2. At this time, the worker can operate the link rod 18 or the rod body 1 to drag the branch, so that the branch is broken under the combined action of shearing force and pulling force. This structure can achieve tree pruning by cutting and pulling.

[0039] 4. First claw 14 and second claw 15;

[0040] like Figure 5As shown, a first claw 14 and a second claw 15 are provided on the shell 9, and the first claw 14 is recessed toward the second claw 15, and the second claw 15 is recessed toward the first claw 14. An approximately circular clamping space 16 is formed between the first claw 14 and the second claw 15, and the clamping space 16 is adapted to the rod body 1 or the link rod 18. Adaptation here means that the size of the clamping space 16 is equal to the outer diameter of the rod body 1, or the size of the clamping space 16 is equal to the outer diameter of the link rod 18, and the size of the opening 17 of the clamping space 16 is smaller than the outer diameter of the rod body 1 or the link rod 18, so that the first claw 14 and the second claw 15 can be firmly clamped. This structure enables the remote control assembly 8 to be fixed on the rod body 1 or the link rod 18, and only one worker is needed to press the operation button 12 and prune trees.

[0041] In this embodiment, the first clamping claw 14 and the second clamping claw 15 are both made of plastic material and have a certain deformation ability. That is, when the opening 17 of the clamping space 16 contacts the rod body 1 or the link rod 18, the first clamping claw 14 and the second clamping claw 15 will expand slightly outward to allow the rod body 1 or the link rod 18 to enter the clamping space 16.

[0042] This embodiment can not only cut branches, but also break branches by pulling when the branches are too hard to be cut, thereby reducing the failure rate of the power distribution line; this embodiment controls the rotation of the movable blade 4 by the remote control component 8 to achieve cutting, which saves time and effort.

[0043] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
