Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, in particular to a device for removing bird nests from high-voltage line towers. Background Art

[0002] As an important infrastructure for power transmission, the safety of high-voltage towers is receiving more and more attention. However, high-voltage towers often become nesting sites for birds. The branches, grass and other debris in the bird nests not only affect the efficiency of power transmission, but may also cause line failures or even fires, seriously threatening the safe operation of the power grid.

[0003] Bird nests on high-voltage lines are often large and complex in structure. Existing clamping or hooking methods are difficult to quickly and effectively handle large-sized bird nests, resulting in a long removal time. Operators need to adjust the position several times and gradually remove the bird nests in sections, which increases the operation time and difficulty, especially in high-altitude working environments. This not only reduces work efficiency, but also increases safety risks.

[0004] In addition, some materials in bird nests (such as branches, straw ropes, etc.) will be entangled on high-voltage lines or tower structures. Existing clamping or hooking tools cannot effectively remove these entanglements, resulting in incomplete demolition and even some residual materials, which continue to threaten the safety of power facilities.

[0005] Therefore, it is necessary to design a device for removing bird's nests from high-voltage towers to solve the above-mentioned technical problems. Summary of the invention

[0006] In response to the above-mentioned problems, the present application provides a device for dismantling bird's nests on high-voltage towers. The preliminary dismantling mechanism is first adjusted upward and the advanced dismantling mechanism is downward. The operator adjusts the opening and closing of the clamping jaws by adjusting the position of the moving clamping jaws, and then the bird's nest is initially dismantled by combining the three methods of poking, clamping and pulling. The preliminary dismantling mechanism and the advanced dismantling mechanism are then reversed, with the advanced dismantling mechanism upward and the preliminary dismantling mechanism downward. The bird's nest is dismantled in a refined manner by adjusting the position of the ring sleeve. Through the two stages of preliminary dismantling and advanced dismantling, bird's nests of different sizes and structures can be handled more effectively, avoiding the problem that a single tool is difficult to cope with complex situations. The orientation of the dismantling tool can be flexibly selected according to the specific situation of the bird's nest, thereby improving the overall dismantling efficiency.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] See also Figure 1-Figure 8 , an embodiment of the present invention provides a device for removing a bird's nest from a high-voltage line tower, comprising:

[0044] Initial dismantling of mechanism 1;

[0045] The outer rod assembly 2 is configured as a plurality of outer rod assemblies 2, which can be fixedly arranged on the upper end of the preliminary removal mechanism 1, and each of the outer rod assemblies 2 can be fixedly arranged, and the upper end of the uppermost outer rod assembly 2 is fixedly arranged with an advanced removal mechanism 3; and

[0046] The inner connecting rod assembly 4 is arranged inside the outer connecting rod assembly 2 , and is arranged corresponding to the outer connecting rod assembly 2 , and the inner connecting rod assembly 4 can be connected to the inner connecting rod assembly 4 .

[0047] Based on the above technical solution, first select the corresponding number of outer rod assemblies 2 and inner connecting rod assemblies 4 according to the height of the bird's nest. For example, if there are two outer rod assemblies 2 and two inner connecting rod assemblies 4, and the outer rod assemblies 2 and the inner connecting rod assemblies 4 are both numbered a and b, then first connect the a inner connecting rod assembly 4 to the preliminary dismantling mechanism 1, then connect the b inner connecting rod assembly 4 to the a inner connecting rod assembly 4, then connect the a outer rod assembly 2 to the preliminary dismantling mechanism 1, then connect the b outer rod assembly 2 to the a outer rod assembly 2, and finally connect the advanced dismantling mechanism 3 to the b inner connecting rod assembly 4 and the b outer rod assembly 4. The sleeve rod assembly 2 is connected. After the assembly is completed, the preliminary demolition mechanism 1 is upward and the advanced demolition mechanism 3 is downward. The operator adjusts the preliminary demolition mechanism 1 by adjusting the advanced demolition mechanism 3, and then performs preliminary demolition of the bird's nest by combining poking, clamping and pulling. Then the preliminary demolition mechanism 1 and the advanced demolition mechanism 3 are turned upside down, the advanced demolition mechanism 3 is upward, and the preliminary demolition mechanism 1 is downward. The operator adjusts the advanced demolition mechanism 3 by adjusting the preliminary demolition mechanism 1, and performs fine demolition of the materials wrapped around the high-voltage line and the materials that are initially difficult to remove of the bird's nest until the nest demolition work is completed.

[0048] Based on the above technical solution, through the two stages of preliminary demolition and advanced demolition, bird's nests of different sizes and structures can be handled more effectively, avoiding the problem that a single tool is difficult to cope with complex situations. The direction of the demolition tool can be flexibly selected according to the specific situation of the bird's nest, thereby improving the overall demolition efficiency.

[0049] It should be added that, according to the height of the bird's nest, a corresponding number of outer rod assemblies 2 and inner connecting rod assembly combinations 4 are selected, and the bird's nest is dismantled after being assembled with the preliminary dismantling mechanism 1 and the advanced dismantling mechanism 3. This makes it suitable for high-voltage line towers of different heights, whether it is a low branch tower or a tall trunk tower, and can effectively cope with it, ensuring that the device can accurately reach the bird's nest position, providing higher flexibility and adaptability.

[0050] In a possible implementation, the preliminary removal mechanism 1 includes:

[0051] The first outer sleeve 111 is hollow, and a through groove 112 is symmetrically formed in the circumferential direction of the first outer sleeve 111, and a first internal thread portion 113 is formed in the circumferential direction of the inner side of the upper end of the first outer sleeve 111;

[0052] A first inner sleeve rod 114 is movably disposed in the first outer sleeve 111, and a shaft rod 115 is symmetrically fixedly disposed on the circumference of the first inner sleeve rod 114. The shaft rod 115 is movably disposed in the through slot 112, and one end of the shaft rod 115 extending out of the through slot 112 is fixedly disposed with a ring sleeve 116, and a first inner slot 117 is formed at the upper end of the first inner sleeve rod 114;

[0053] The clamping jaws 119 are configured as at least three and are all rotatably disposed on the ear seats 118. The ear seats 118 are fixedly disposed in an annular array on the circumference of the first outer sleeve 111 away from the first internal threaded portion 113; and

[0054] The multi-phase U-shaped frame 120 is fixedly arranged at the center position of one end of the first inner sleeve rod 114 away from the first inner threaded portion 113. The multi-phase U-shaped frame 120 is rotatably provided with a coupling plate 121 in the circumferential direction. The coupling plate 121 is arranged corresponding to the clamping claw 119, and the coupling plate 121 is hingedly arranged with one end of the clamping claw 119 close to the center axis of the first inner sleeve rod 114.

[0055] Through the above technical solution, such as Figure 3 As shown, when the first inner sleeve rod 114 rises in the first outer sleeve 111, the multi-phase U-shaped frame 120 rises, the coupling plate 121 rotates, and the clamping jaws 119 move toward an open state; when the first inner sleeve rod 114 descends in the first outer sleeve 111, the multi-phase U-shaped frame 120 descends, the coupling plate 121 rotates in the opposite direction, and the clamping jaws 119 move toward a closed state, that is, during the initial demolition, the clamping jaws 119 are in a closed state, and the bird's nest can be poked when the initial demolition mechanism 1 is upward as a whole, and then the initial demolition mechanism 1 is controlled to descend so that the clamping jaws 119 open, and then the clamping jaws 119 are controlled to move from an open state to a closed state during the ascending process to clamp the bird's nest, and when the operator pulls the initial demolition mechanism 1 downward as a whole, the bird's nest is pulled, and the bird's nest can be initially demolished at this time.

[0056] In a possible embodiment, the outer rod assembly 2 includes: an outer rod 21, which is hollow and has a second internal threaded portion 22 on the inner circumference of the upper end of the outer rod 21, and a first external threaded portion 23 on the outer circumference of the lower end of the outer rod 21.

[0057] In a possible implementation, the advanced removal mechanism 3 includes:

[0058] The second outer sleeve 31 is hollow, and an annular boss 32 is fixedly provided on its upper end. A second external threaded portion 33 is provided on the outer circumference of the lower end of the second outer sleeve 31;

[0059] A second inner sleeve rod 34 is movably disposed in the second outer sleeve 31, a movable clamping claw 36 is rotatably disposed at the upper end of the second outer sleeve 31, and a first clamping platform 39 is fixedly disposed at the lower end of the second outer sleeve 31; and

[0060] The fixed claw 35 has its lower end fixedly arranged on the upper end of the annular boss 32, and the fixed claw 35 is rotatably arranged with the movable claw 36. A blade 37 is detachably fixedly arranged on the movable claw 36, and a spring 38 is sleeved on the circumference of the second inner sleeve rod 34 between the rotating connection between the movable claw 36 and the second inner sleeve rod 34 and the annular boss 32.

[0061] Using the above technical solution, such as Figure 5 As shown, when the second inner sleeve rod 34 rises in the second outer sleeve 31, the movable claw 36 rotates clockwise along the fixed claw 35, and the movable claw 36 and the fixed claw 35 are in an open state; after the blade 37 and the movable claw 36 are fixed, when the second inner sleeve rod 34 descends in the second outer sleeve 31, the spring 38 is compressed, and the movable claw 36 rotates counterclockwise along the fixed claw 35, and the movable claw 36 and the fixed claw 35 are in a closed state. At this time, the materials of the bird's nest wrapped around the high-voltage line or the tower structure and the materials that are initially difficult to remove can be correspondingly sheared, clamped and removed, so as to effectively deal with tightly wrapped materials such as branches, straw ropes, etc., and through precise shearing, the entangled objects can be quickly cut off, which reduces the removal time, ensures that each shearing and clamping can be completely removed, and avoids the residues from continuing to threaten the safety of power facilities.

[0062] It should be noted that the detachable connection between the blade 37 and the movable clamping claw 36 can effectively prevent personal safety problems that may occur when the operator pinches the movable clamping claw 36 and the fixed clamping claw 35, thereby reducing the occurrence of safety accidents.

[0063] In a possible implementation manner, the inner connecting rod assembly 4 includes: an inner connecting rod 41 , the upper end of which is provided with a second inner clamping groove 42 , and the lower end of the inner connecting rod 41 is fixedly provided with a second clamping platform 43 .

[0064] In a possible implementation manner, the first internal threaded portion 113 is threadedly connected to the first external threaded portion 23 , so that the outer sleeve rod assembly 2 is connected to the preliminary removal mechanism 1 .

[0065] In a possible implementation manner, the first inner clamping groove 117 is arranged corresponding to the second clamping platform 43 , that is, the inner connecting rod assembly 4 can be connected to the preliminary dismantling mechanism 1 .

[0066] In a possible embodiment, the second internal threaded portion 22 is threadedly connected to the second external threaded portion 33, and the second internal threaded portion 22 can be threadedly connected to the first external threaded portion 23, that is, the outer sleeve rod assembly 2 can be connected to the advanced removal mechanism 3, and the outer sleeve rod assembly 2 can be connected to the outer sleeve rod assembly 2.

[0067] In a possible embodiment, the first clamping platform 39 is arranged corresponding to the second inner clamping groove 42, and the second inner clamping groove 42 is arranged corresponding to the second clamping platform 43, that is, the inner connecting rod assembly 4 can be connected to the advanced dismantling mechanism 3, and the inner connecting rod assembly 4 can be connected to the inner connecting rod assembly 4.

[0068] It should be supplemented that when the first inner slot 117 is engaged with the second platform 43, the first platform 39 is engaged with the second inner slot 42, and the second inner slot 42 is engaged with the second platform 43, the first inner sleeve 114, the inner connecting rod 41 and the second inner sleeve 34 can move in coordination along the central axis of the first outer sleeve 111, the second outer sleeve 31 and the outer sleeve rod 21.

[0069] In a possible implementation manner, the outer rod 21 is disposed corresponding to the inner connecting rod 41 , and the inner connecting rod 41 is movably disposed in the outer rod 21 .

[0070] By means of the above technical solution, during the initial removal, the initial removal mechanism 1 is upward, and the advanced removal mechanism 3 is downward, and when the movable clamping claw 36 and the fixed clamping claw 35 are pinched, the second inner sleeve rod 34 rises in the second outer sleeve 31, the spring 38 is compressed, and the clamping claw 119 moves toward the open state. After the movable clamping claw 36 is released, the spring 38 recovers its deformation, and the clamping claw 119 can be closed, that is, the clamping claw 119 is in a closed state at the beginning. When the advanced removal mechanism 3 and the outer sleeve rod assembly 2 are pulling, the opening degree of the movable clamping claw 36 and the fixed clamping claw 35 is maintained so that the clamping claw 119 can be closed. 9 remains in a closed state; during advanced dismantling, the advanced dismantling mechanism 3 moves upward, the preliminary dismantling mechanism 1 moves downward, and the ring sleeve 116 is dragged downward. When the second inner sleeve rod 34 descends in the second outer sleeve 31, the spring 38 is compressed, and the movable claw 36 rotates counterclockwise along the fixed claw 35. The movable claw 36 and the fixed claw 35 move toward a closed state. At this time, the materials of the bird's nest wrapped around the high-voltage line or the tower structure and the materials that are initially difficult to remove can be correspondingly sheared, clamped and dismantled. After the spring 38 recovers, the movable claw 36 and the fixed claw 35 are in an open state.

[0071] In a specific implementation, first select the corresponding number of outer rod assemblies 2 and inner connecting rod assemblies 4 according to the height of the bird's nest. Taking the example of two outer rod assemblies 2 and two inner connecting rod assemblies 4, the outer rod assemblies 2 and the inner connecting rod assemblies 4 are numbered a and b, then first clamp the second clamping platform 43 of the inner connecting rod assembly 4 of a into the first inner clamping groove 117, then clamp the second clamping platform 43 of the inner connecting rod assembly 4 of b into the second inner clamping groove 42 of the inner connecting rod assembly 4 of a, then threadably connect the second internal threaded portion 22 of the outer rod assembly 2 of a with the first external threaded portion 23 of the outer rod assembly 2 of b, then threadably connect the first external threaded portion 23 of the outer rod assembly 2 of a with the first internal threaded portion 113, then clamp the second internal clamping groove 42 of the inner connecting rod assembly 4 of b with the first clamping platform 39, and rotate The second outer sleeve 31 makes the second internal threaded portion 22 of the b outer sleeve rod assembly 2 threadedly connected with the second external threaded portion 33. After the assembly is completed, the preliminary dismantling mechanism 1 is upward and the advanced dismantling mechanism 3 is downward. The operator adjusts the opening and closing degree of the clamping jaw 119 by adjusting the position of the movable clamping jaw 36, and then performs preliminary dismantling of the bird's nest by combining the three methods of poking, clamping and pulling. Then the preliminary dismantling mechanism 1 and the advanced dismantling mechanism 3 are reversed, the advanced dismantling mechanism 3 is upward, the preliminary dismantling mechanism 1 is downward, and then the blade 37 is fixed with the movable clamping jaw 36. By adjusting the position of the ring sleeve 116, the movable clamping jaw 36 and the blade 37 are deflected together and then cooperated with the fixed clamping jaw 35 to carry out fine dismantling of the materials wrapped around the high-voltage line and the materials that are initially difficult to remove in the bird's nest until the nest dismantling work is completed.

[0072] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
