Description

Technical Field

[0001] The present invention relates to the technical field of electric power safety equipment, and particularly relates to a magnet type bird-preventing placeholder that is easy to install. Background Art

[0002] A bird-preventing placeholder is a device used to drive birds away from staying and nesting on distribution lines. Most of them are installed on the cross arms of poles and towers. Each installation is carried out when the line is powered off. Workers climb the poles and towers to install it, fixing the card slot at the lower end of the bird-preventing placeholder on the cross arm of the pole. During installation, power outage not only causes less power supply but also affects the power supply reliability of users. The installation process poses a safety hazard to workers.

[0003] Therefore, the present application designs a magnet type bird-preventing placeholder that is easy to install to solve the above problems. Summary of the Invention

[0004] The present invention provides a magnet type bird-preventing placeholder that is easy to install to make up for the deficiencies in the prior art.

[0005] A magnetic adsorption fixing device is provided at the bottom of the bird-preventing placeholder body, and an insulating rod is provided in a supporting manner. After initially fixing the bird-preventing placeholder body on the cross arm through the insulating rod, the insulating rod is adjusted to make the magnetic adsorption fixing device adsorb the cross arm. An additional clamping piece is provided at the bottom of the bird-preventing placeholder body, which can clamp the cross arm while the magnetic adsorption fixing device adsorbs the cross arm.

[0006] Further, to better implement the present invention, a U-shaped seat is provided at the bottom of the bird-preventing placeholder body. A threaded through hole is opened at the center of the bottom of the U-shaped seat, and the magnetic adsorption fixing device is threadedly connected in the threaded through hole.

[0007] Further, to better implement the present invention, the magnetic adsorption fixing device includes a threaded column threadedly connected to the threaded through hole. The top of the threaded column is connected with a lifting disc through a bearing. A main magnet is embedded on the lifting disc. A hexagonal nut is provided at the bottom of the threaded column. The threaded column is rotated by the sleeve at the top of the insulating rod, thereby controlling the main magnet to rise and lean against the cross arm.

[0008] Further, to better implement the present invention, the magnetic adsorption fixing device further includes a secondary magnet embedded in the bent arm of the U-shaped seat. The secondary magnet can adsorb the side surface of the cross arm and the insulating rod.

[0009] Further, to better implement the present invention, the middle of the insulating rod is hollowed out with an activity groove. A magnetic adsorption rod is hinged in the activity groove through a hinge shaft. An iron block is installed at the top of the magnetic adsorption rod. One side of the bottom of the magnetic adsorption rod bulges outwards and is connected with a spring between the bottom of the insulating rod.

[0010] Further, to better implement the present invention, the additional clamping piece is an elastic bent plate, which is installed on the inner top of the U-shaped seat. The cross arm can enter the U-shaped seat after flattening the additional clamping piece. A limiting hole is opened on the lifting plate of the magnetic attraction fixing device, and a limiting sliding column fixed on the U-shaped seat is slidably connected in the limiting hole. A top block is arranged on the lifting plate. When the top block moves upward, it pushes the additional clamping piece to clamp the side surface of the cross arm.

[0011] The beneficial effects of the present invention are as follows: The device of the present invention preliminarily fixes the anti-bird occupancy device on the cross arm quickly through the insulating rod, and then tightens the anti-bird occupancy device through the insulating rod. The whole process does not require power outage of the distribution line, and even less does it require the staff to climb the pole, thereby increasing the power supply of the distribution line, increasing the income, and avoiding the occurrence of personal accidents.

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0016] Figures 1 - 5 For a specific embodiment of the present invention, the magnet type anti-bird occupying device in this embodiment includes an anti-bird occupying device body 1, and a U-shaped seat 101 is welded or integrally formed at its bottom. The U-shaped seat 101 is made of aluminum alloy with a thickness of 3 mm, a width of 80 mm, a depth of 50 mm, and the height of the bent arms on both sides is 30 mm. A threaded through hole 102 is opened at the center of the bottom of the U-shaped seat 101, the diameter of the through hole is 10 mm, the pitch is 1.5 mm, and it is precisely matched with the threaded column 201 of the magnetic attraction fixing device 2.

[0017] The magnetic attraction fixing device 2 is composed of the following components: Threaded column 201: with a length of 60 mm, made of stainless steel, the bottom is processed into a hexagonal nut (edge distance 12 mm), and the top is connected to the lifting disc 202 through a ball bearing (model 608ZZ); Lifting disc 202: a circular steel plate with a diameter of 40 mm and a thickness of 5 mm, and a main magnet 203 is embedded in the center; Main magnet 203: a neodymium iron boron permanent magnet, with dimensions of 30 mm × 30 mm × 10 mm, a magnetic force grade of N42, and the surface is nickel-plated for corrosion prevention.

[0018] During operation, the anti-bird occupying device body 1 is lifted to one side of the cross arm 4 through the insulating rod 3, so that the opening of the U-shaped seat 101 faces the cross arm 4. Then the U-shaped seat 101 is pushed into the cross arm 4. After the secondary magnet 204 adsorbs the cross arm 4, the threaded column 201 is rotated through the sleeve 306 (inner diameter 12 mm, matching the hexagonal nut) at the top of the insulating rod 3. For each rotation, the lifting disc 202 rises 1.5 mm. When the main magnet 203 contacts the bottom surface of the cross arm 4, continue to rotate 90° - 180°, so that the magnetic attraction force reaches a maximum value of about 200 N to complete the fixation.

[0019] A secondary magnet 204, a neodymium iron boron magnet (N35 grade) with a diameter of 15 mm and a thickness of 5 mm, is embedded in the bent arm of the U-shaped seat 101. When the distance from the side of the cross arm 4 is ≤ 2 mm, an adsorption force of ≥ 50 N can be generated to further inhibit the lateral displacement of the device.

[0020] The additional clamping piece 5 is a 65Mn spring steel sheet with a thickness of 1.2mm and a bending angle of 40°, and is installed on the top of the inner side of the U-shaped seat 101. When the cross arm 4 is pressed into the U-shaped seat, the clamping piece 5 is compressed to a horizontal state. After the cross arm 4 is fully inserted, the additional clamping piece 5 rebounds to the initial angle. The top block 501 set on the lifting plate 202 will push the additional clamping piece 5 during the rising process, so that it presses against the side wall of the cross arm 4, forming a double fixation with the magnetic attraction. The edge of the lifting plate 202 is provided with a limit hole with a diameter of 8mm, which is slidably connected with the limit sliding column 502 (diameter 7.8mm, clearance fit) on the U-shaped seat 101 to ensure that the lifting plate 202 only moves in the vertical direction.

[0021] The insulating rod 3 is made of epoxy resin, with a total length of 2.5m and an outer diameter of 40mm. The inside is hollowed out to form a movable groove 301 (width 15mm). The magnetic rod 302 is hinged in the movable groove through a stainless steel hinge shaft 304 (diameter 5mm). An iron block 303 (size 20mm×20mm×5mm) is welded on the top, and a spring 305 is connected between the bottom raised part and the insulating rod 3. During operation, the iron block 303 will absorb the secondary magnet 204 of the U-shaped seat 101. When the U-shaped seat 101 is placed on the cross arm 4, hold the handle at the end of the magnetic rod 302 tightly, and the top of the magnetic rod 302 will bounce back around the hinge shaft 304, so that the iron block 303 will be separated from the U-shaped seat 101 (this is a labor-saving operation. If the insulating rod 3 is pulled out directly, it will obviously be more laborious). Then, the sleeve 306 at the top of the insulating rod 3 is inserted into the threaded column 201, and then it can be twisted to drive the main magnet 203 to absorb the cross arm 4 upward.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
