Description

Technical Field

[0001] This utility model relates to the field of power systems, specifically to a fixture for disassembling and assembling a suspended ultrasonic bird repeller. Background Technology

[0002] In the field of power system operation and maintenance, bird control of transmission lines, substations, and other equipment is a crucial aspect of ensuring the safe operation of the power grid. Suspended ultrasonic bird repellers, as a highly efficient bird deterrent device, are widely used in high-voltage transmission line towers, substation structures, and other applications. They achieve bird deterrence through ultrasonic interference, reducing bird droppings pollution, nesting, short circuits, and other potential hazards.

[0003] Currently, the installation and disassembly of suspended ultrasonic bird repellers mostly require an electrified environment. Existing tools for assembling and disassembling bird repellers have the following problems:

[0004] High operational complexity: Existing tools often require workers to directly contact live parts or perform multi-step operations. With the limitations of protective equipment such as insulating gloves and insulating rods, the flexibility of operation is low, and the work efficiency is low due to deformation of the movement. It also increases the risk of accidentally touching live parts.

[0005] Poor adaptability: The fixing of bird repellers and cables mostly relies on bolts, cable ties and other structures. Special tools are required to unlock them one by one when disassembling and assembling them. It is difficult to adapt to the rapid operation requirements of different specifications of bird repellers. Especially in high-altitude and confined spaces, the alignment accuracy between tools and bird repellers is insufficient, which can easily cause component wear or insecure installation. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a suspended ultrasonic bird deterrent assembly and disassembly fixture, so as to enable the safe and rapid assembly and disassembly of bird deterrents in high-voltage live environments, improve work efficiency, and reduce maintenance risks.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a suspended ultrasonic bird repeller assembly and disassembly fixture, comprising an assembly tray and a bird repeller body, wherein the upper end of the assembly tray is hinged with pull strips on the front and rear sides, the assembly tray is provided with hinged parts on both sides, and the assembly tray is provided with through mounting grooves in the middle of both sides.

[0010] Preferably, a rocker arm is hinged to the inner side of the hinge portion and connected by a male and female bolt. An elastic connecting rod is hinged to the bottom of the rocker arm. The other end of the elastic connecting rod is connected to the end of the pull bar. A spring is engaged in the middle of the male and female bolt, and a buckle is fixed to the end of the spring.

[0011] Preferably, a pull ring positioning pin is provided at the bottom of the pull bar.

[0012] Preferably, the mounting tray has a hollow box structure with an operating handle at the bottom.

[0013] Preferably, the bird deterrent device body includes a mounting base and spring baffles sleeved on both sides of the mounting base and movable up and down along its axial direction. Two sets of side wings are symmetrically arranged on both sides of the mounting base. A fixed shaft is fixedly installed on the top of each side wing. A torsion spring is rotatably sleeved on the fixed shaft. When the spring baffles move downward along the mounting base, the crossbars of the torsion springs on both sides release the obstruction of the spring baffles and can automatically reset, so as to achieve clamping of the cable.

[0014] Preferably, a compression spring is provided between the mounting base and the spring stop plate. A V-shaped drive block is integrally formed at the bottom upper end of the spring stop plate. When the V-shaped drive block moves downward under the action of external force, it can drive the spring stop plate to descend synchronously and compress the compression spring, so that the torsion springs on both sides can release the obstruction and complete the clamping action of the cable.

[0015] Preferably, the inner edge of the rocker has an arc-shaped protrusion to prevent the bird deterrent device from falling off.

[0016] Preferably, the end of the buckle is provided with a wedge-shaped locking head, which is adapted to the end of the spring stop.

[0017] Preferably, after the pull ring positioning pin is released, pulling the pull ring at the end of the pull bar can cause the rocker to naturally unfold outward; when the mounting tray rises and contacts the bird repeller body, the bottom of the bird repeller body can squeeze the rocker to make it rotate upward, and then push the pull bar inward to clamp the bird repeller body through the elastic connecting rod. Pulling the operating handle downward can release the torsion spring and complete the disassembly.

[0018] (III) Beneficial Effects

[0019] This utility model effectively solves many pain points in the live-line installation of existing suspended ultrasonic bird repellers through optimized structural design, and its specific benefits are as follows:

[0020] Significantly improves operational safety: The installation tray and operating handle are designed with integrated insulating materials, and the linkage structure of the pull bar and rocker allows workers to complete the operation while maintaining a safe distance, avoiding direct contact with live parts; the buffer mechanism composed of springs and elastic linkages can stably control the operating force, reducing the risk of loss of control of the safe distance due to excessive operating amplitude, and fundamentally reducing the probability of phase-to-phase short circuits and electric shock accidents.

[0021] Simplify the operation process and improve work efficiency: The pull bar is quickly fixed in an inverted "8" shape by the pull ring positioning pin. Automatic clamping is achieved through the linkage of V-shaped drive block and spring baffle. During disassembly, the mechanical transmission of rocker plate and elastic connecting rod completes the tightening and separation. The traditional multi-step operation is integrated into a continuous action, which greatly shortens the disassembly and assembly time of a single set of equipment. It is especially suitable for high-altitude and confined environments.

[0022] In summary, this utility model achieves a "safe, controllable, efficient, convenient, and highly adaptable" live-line installation operation mode through structural innovation, providing reliable technical support for the prevention and control of bird damage in power grids.

Detailed Implementation

[0031] The following will refer to the appendix in the example of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Example 1: The suspended ultrasonic bird repeller assembly and disassembly fixture provided in this example has the following structure:

[0033] like Figure 1 As shown, it mainly consists of a mounting tray 1, a bird deterrent body 9, and linkage operation components. The mounting tray 1 serves as the supporting base and is connected to the operation components through multiple sets of hinge structures. The bird deterrent body 9 is detachably connected to the mounting tray 1 through buckles 7, forming an integrated fixture with positioning, clamping, and driving functions.

[0034] The mounting tray 1 is made of high-strength insulating material such as epoxy resin and glass fiber, forming a hollow box structure. An operating handle 13 is vertically connected to the bottom, and the surface is provided with anti-slip texture. Symmetrical through-type mounting grooves 12 are opened in the middle of the two side walls of the mounting tray 1 to accommodate the position of the rocker 3; the top of both sides extend outward to form hinge parts 11.

[0035] The pull rod 2 is bent and has hinge holes at both ends. The pull rod 2 is connected to the front and rear sides of the upper end of the mounting bracket 1 by bolts and can rotate around the hinge axis. A pull ring positioning pin 8 is provided at the bottom of the pull rod 2 to secure the circular pull ring at the end of the pull rod.

[0036] The rocker arm 3 has a planar structure with an arc-shaped protrusion near the inner side to prevent the bird deterrent body 9 from falling off. A hinge hole is located at the corner, connecting it to the hinge part 11 of the mounting bracket 1 via a bolt 4. An elastic connecting rod 5 is hinged to the bottom end of the rocker arm 3, allowing it to extend and retract. The other end of the elastic connecting rod 5 is hinged to the end of the pull bar 2, forming a triangular transmission structure. A spring 6, made of 65Mn spring steel, is sleeved in the middle of the bolt 4. One end of the spring 6 is connected to the inner side of the rocker arm 3, and the other end is fixedly connected to the buckle 7. The buckle 7 is made of wear-resistant alloy, with a wedge-shaped head at the end that matches the upper end of the bird deterrent spring stop 92. The surface of the head has a certain degree of hardness.

[0037] The bird deterrent device body 9 includes a mounting base 91 and spring baffles 92 that are sleeved on both sides of the mounting base 29 and can move up and down along its axial direction. Two sets of side wings 211 are symmetrically arranged at both ends of the mounting base 91. A stainless steel fixing shaft 93 is vertically fixed to the upper surface of each set of side wings, and an anti-detachment retaining ring is provided at the shaft end. The spring baffles 92 are arc-shaped steel plates, sleeved on both sides of the vertical beam of the mounting base 91, and can slide up and down along the axial direction. A torsion spring 94 is rotatably sleeved on the fixing shaft 93, and the end of its crossbar contacts the inner side of the spring baffle 92. A compression spring 95 is provided inside the vertical beam of the mounting base 91, one end abutting against the bottom of the mounting base, and the other end contacting the lower end face of the spring baffle 92. A V-shaped drive block 96 is integrally formed at the upper bottom of the spring baffle 92, forming a surface contact fit with the wedge-shaped locking head of the latch 7.

[0038] Working principle:

[0039] I. Installation process (e.g.) Figure 6 (As shown)

[0040] Initial fixing stage: First, insert the bird repeller body 9 into the mounting tray 1, then insert the pull ring positioning pin 8 into the corresponding hole of the mounting tray 1 to fix the position of the pull strip 2. At this time, the pull strips 2 on both sides are unfolded in an inverted "V" shape, and the rocker plate 3 remains perpendicular to the mounting plane in the initial state. Next, pull the buckle 7 to make it engage with the spring stop plate 92 of the bird repeller body 9. The arc-shaped protrusion 31 serves as the first anti-loosening safety, further preventing the bird repeller body (9) from falling off during installation and ensuring that it is relatively fixed to the mounting tray (1).

[0041] Clamping action triggering stage: The operator holds the operating handle 13, causing the V-shaped drive block 96 of the bird deterrent body 9 to contact and be squeezed with the target cable. Under pressure, the V-shaped drive block 96 moves downward, synchronously driving the spring baffle 92 to descend along the axial direction of the mounting base 91, thus initiating the linkage action of the clamping mechanism.

[0042] Clamping and unlocking phase: After the spring stop 92 descends, it releases the obstruction constraint on the torsion springs 94 on both sides. The torsion springs 94 automatically reset around the fixed shaft 93, and their crossbars tighten inward and tightly grip the cable, completing the stable clamping of the cable. At the same time, the downward displacement of the spring stop 92 causes the buckle 7 to disengage from the spring stop 92, automatically releasing the anti-fall constraint, and the installation operation is now complete.

[0043] II. Disassembly process (e.g.) Figure 7 (As shown)

[0044] Initial fixing and unlocking stage: First, loosen the locating pins 8 at both ends of the pull ring to release their fixing effect on the pull bar 2. Then, pull the pull ring at the end of the pull bar 2 to allow the rocker plate 3 to unfold outward naturally, leaving space for the mechanism linkage during disassembly.

[0045] Linkage clamping stage: The operating handle 13 drives the mounting tray 1 to engage with the bird repeller body 9. As the mounting tray 1 rises, the bottom of the bird repeller body 9 gradually contacts and presses against the rocker arm 3. The rocker arm 3 rotates upward around the hinge 11, simultaneously driving the elastic connecting rod 5 to push the pull bars 2 on both sides inward to tighten and clamp the bird repeller body 9, forming a reliable disassembly connection.

[0046] Disassembly completion stage: The operator pulls the operating handle 13 downwards with force. Under the action of the pulling force, the torsion spring 94 on the bird deterrent body 9 is forced to open outwards, releasing the clamping constraint on the cable, and finally completing the separation of the bird deterrent body 9 from the cable, thus ending the disassembly operation.

[0047] The entire working process, through the precise linkage of the mechanical structure and the reset characteristics of the spring, enables the bird deterrent to be safely and efficiently disassembled and assembled in an electrified environment. The actions of each step are logically consistent, and the operational stability and reliability are significantly improved.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
