Description
Technical Field
[0001] This utility model relates to a magnetic bird deterrent device for power transmission lines, belonging to the field of power engineering safety technology. Background Technology
[0002] With the improvement of the ecological environment, large flocks of birds have been attracted to nest along many power transmission lines, threatening the safe operation of the power grid. Therefore, power maintenance personnel install bird deterrents near transmission lines to drive away flocks of birds and reduce bird-related accidents. Magnetic bird deterrents are widely used because they can be directly attached to metal components near transmission lines, making installation convenient. However, after a period of use, we have found several problems: First, installation is inconvenient under high-voltage, high-altitude conditions, requiring the cooperation of multiple equipment and operators, which is time-consuming and labor-intensive; second, installation relies entirely on metal mounting surfaces and cannot be used on non-magnetic materials such as cement towers and glass insulators; third, if the mounting surface has rust or protrusions, the adhesion will decrease, making it easy to fall off and posing a safety hazard. Therefore, this application proposes a novel bird deterrent device to solve the above problems. Utility Model Content
[0003] In view of the shortcomings of the prior art, the problem to be solved by this utility model is to provide a magnetic bird deterrent device for power transmission lines that has a reasonable structural design, can be easily installed under high-altitude and high-voltage conditions, improves installation efficiency, has good installation firmness, and ensures the safe operation of power transmission lines.
[0004] The technical solution adopted by this utility model to solve its technical problem is: The aforementioned magnetic bird deterrent device for power transmission lines includes a pole and a bird deterrent device. A lifting rod is slidably connected to the inner side of the pole, and the bird deterrent device is installed at the top of the lifting rod. A fixing plate is fixedly connected to the bottom of the inner side wall of the lifting rod. The fixing plate is provided with toothed grooves, and a circular gear is provided corresponding to the toothed grooves and meshing with them. The circular gear is located inside the pole and is connected to the power output end of the drive motor through a coupling. The drive motor is fixedly installed on the outer side of the pole. A connecting block is provided at the bottom of the pole, and a first clamp and a second clamp are rotatably connected to both sides of the connecting block, respectively. The first clamp and the second clamp are fixedly connected through a connecting assembly.
[0005] The magnetic bird deterrent device for power transmission lines is easy to install and fix. The device can be directly mounted on the power transmission pole. At the same time, the bird deterrent device can be adjusted to the position of the high-altitude high-voltage power transmission line through the lifting pole to deter birds. This realizes convenient installation under high-altitude high-voltage energized conditions and ensures the safe operation of the power transmission line.
[0006] In a further preferred embodiment, a sliding rod is provided at the top of the lifting rod, and a movable groove is provided on the side of the upright corresponding to the sliding rod. One end of the sliding rod is connected to a straight hook, and the other end of the straight hook is fixedly connected to a bearing. A hook is fixedly connected to both sides of the outer periphery of the bearing, and the hook is connected to the bird deterrent device, which facilitates the installation of the bird deterrent device and the adjustment of its height position.
[0007] In a further preferred embodiment, the connecting assembly includes a tapered compression spring, one end of which is fixedly connected to the end of the first clamp, and the other end of which is fixedly connected to a threaded connecting rod. The threaded connecting rod passes through a positioning hole provided at the end of the second clamp and is then fixed by a fixing nut, making the connection and fixing convenient.
[0008] In a further optimization, the slide bar and the movable groove are located on the same straight line, and the slide bar and the movable groove are in clearance fit, which facilitates the adjustment of the height of the lifting rod.
[0009] In a further preferred embodiment, the fixing plate has a U-shaped structure, with the bottom end of the fixing plate extending to the bottom of the inner wall of the upright.
[0010] Further optimization involves the first and second clamps being symmetrical semi-circular structures, suitable for columnar cement poles, and easy to install and fix.
[0011] The beneficial effects of this utility model are as follows: 1. The magnetic bird deterrent device for power transmission lines described in this utility model can directly adsorb the bird deterrent to the end of the bearing shaft and be engaged by two hooks, which realizes the quick installation of the bird deterrent and the good installation firmness. At the same time, it can also avoid the bird deterrent from falling off due to problems such as rust and protrusion on the installation surface of power transmission line equipment, thus improving the safety of use.
[0012] 2. The magnetic bird deterrent device for power transmission lines described in this utility model, by setting a clamp, can not only be installed on non-magnetic materials, thus expanding the application range of magnetic bird deterrents, but also achieves rapid installation and fixation under high-voltage and high-altitude conditions. This solves the problem that traditional bird deterrents require coordination of multiple equipment and operators for live installation, saving time and effort and greatly improving installation efficiency.
[0013] 3. The magnetic bird deterrent device for power transmission lines described in this utility model can also adjust the height of the bird deterrent device through the cooperation of the motor and the lifting rod. It can raise the bird deterrent device to the high altitude and high voltage power transmission line position to deter birds, reducing the occurrence of bird-related accidents. It has a simple structure, reasonable design, and strong practicality. Attached Figure Description
