[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1

[0029] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a tree obstacle clearing device for power transmission and distribution lines, including a fixed plate 100, a motor 200 is installed on the fixed plate 100, a crank arm 300 is connected to the output end of the motor 200, a telescopic rod 500 is movably connected to the crank arm 300, a rope saw 400 is fixedly connected to the telescopic rod 500, the rope saw 400 has a length of 5 meters and a diameter of 5 mm, a wire recovery arm 600 is connected to the rope saw 400, and the wire recovery arm 600 can be telescopic.

[0030] The crank arm 300 includes a swing rod 301 fixedly connected to the output end of the motor 200, a connecting rod 302 rotatably connected to the swing rod 301, the connecting rod 302 is rotatably connected to the telescopic rod 500, a fixing seat 303 is fixedly arranged on the side of the fixing plate 100, and the telescopic rod 500 is slidably sleeved in the fixing seat 303. The fixing seat 303 can limit the movement path of the telescopic rod 500, so that the telescopic rod 500 can only perform linear telescopic movement, which is convenient for the rope saw 400 to cut tree barriers. The output end of the motor 200 drives one end of the handle to rotate, thereby driving the connecting rod 302 to move as a whole through the end of the connecting rod 302 away from the motor 200, thereby driving the telescopic rod 500 to move. Because the telescopic rod 500 is limited by the fixing seat 303 and can only perform linear telescopic movement, it can drive the rope saw 400 and the end connected to the telescopic rod 500 to move synchronously.

[0031] The fixed plate 100 is bent, and the motor 200 and the crank arm 300 are respectively arranged on both sides of the lower plate of the fixed plate 100, leaving independent and sufficient activity space for movable parts such as the crank arm 300. The lower part of the bent surface on the fixed plate 100 is fixedly connected to the protective shell 101 by bolts. The fixed plate 100, the crank arm 300 and the fixed seat 303 are all arranged inside the protective shell 101. The protective shell 101 can surround the movable parts arranged on the fixed plate 100 inside to prevent accidental injury to the staff. The integrated setting is also more convenient for users to operate.

[0032] A connecting piece 102 is provided on the protective shell 101, and a mounting piece 103 is rotatably provided on the connecting piece 102. A mounting piece 103 is also rotatably provided on the wire recovery arm 600. Fixing pieces 104 are installed on both mounting pieces 103. The fixing pieces 104 are used to fix the two ends of the device respectively, without the need for manual fixing by staff.

[0033] The wire pulling recovery arm 600 adopts a gas spring, the piston rod of the gas spring is fixedly connected to the rope saw 400, and the tail of the gas spring is movably connected to the mounting sleeve. The gas spring has the functions of support, buffering, braking, height and angle adjustment. Compared with traditional springs, the gas spring opens or closes relatively slowly during operation, the elasticity changes gently, and is easy to control.

[0034] When the motor 200 drives the crank arm 300 to rotate and tighten the rope saw 400, the gas spring compresses and accumulates force, thereby driving the rope saw 400 to move toward the side of the motor 200. When the electric saw drives the crank arm 300 to loosen the rope saw 400, the gas spring returns to release the force, thereby driving the rope saw 400 to move toward the side of the spring. This is repeated to achieve back and forth cutting of the rope saw 400.

[0035] The telescopic rod 500 and the rope saw 400 are fixedly connected by a carriage screw 700, and the wire recovery arm 600 and the rope saw 400 are also fixedly connected by a carriage screw 700, so as to adjust the tension at different branch heights.

[0036] The motor 200 adopts a DC motor and is powered by a lithium battery with a power supply voltage of 24V and an operating current of 5A. The DC motor 200 is powered by a lithium battery and a wireless remote controller is installed on the control circuit, allowing personnel to remotely operate the device while ensuring a safe distance. The remote control distance is within 10 meters.

[0037] In summary, when using the device, the wire saw 400 is mounted on the tree branch in the form of a wire saw, and the two ends of the wire saw 400 are respectively installed on the telescopic rod 500 and the wire recovery arm 600 through the carriage screws 700, and then the wire recovery arm 600 and the motor 200 rocker arm are fixed respectively by the fixing part 104. The staff uses the wireless remote control to remotely start the motor 200 to cut the tree barrier.

[0038] Example 2

[0039] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the mounting member 103 includes a cylindrical sleeve 304 and a socket 305.

[0040] When the device needs to be fixed on the ground, the fixing member 104 is preferably a ground rivet, which is tightly fixed and inserted into the columnar sleeve 304. The staff can use a tool to knock the ground rivet into the ground to fix it.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figure 1 to Figure 3 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that when the device needs to be fixed on a tree trunk or other surrounding structures, the fixing member 104 is preferably a ratchet strap.

[0044] The ratchet strap is tightened by rotating the ratchet tensioner to firmly fix the pull wire recovery arm 600 on the tree trunk. The ratchet strap ensures that the strap becomes tighter and tighter through the ratchet mechanism and will not become loose. In addition, the strap has a certain width and is soft, so it is not easy to damage the surface of the tree trunk.

[0045] In addition, when using a ratchet strap, you can easily tighten the strap by simply turning the ratchet, which is labor-saving and convenient to operate. The binding length can be adjusted, and objects of different diameters can be bound.

[0046] The remaining structure is the same as that of Example 2.

[0047] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangement, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present invention.

Therefore, the invention is not limited to a specific embodiment, but extends to numerous modifications still falling within the scope of the appended claims.

[0048] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
