Description

Technical Field

[0001] The utility model relates to the technical field of power systems, in particular to a snake-proof device for electric pole wires. Background Art

[0002] The weather in the south is humid and there are many snakes. The transmission pole guy wires are fixed to the ground with galvanized steel strands and anchored to the ground. Snakes can easily climb onto the poles through the guy wires, which can easily cause the conductors to discharge through the snake's body to the guy wires, causing line tripping accidents. In order to prevent the above accidents from happening, the transmission pole guy wires are currently protected with disc-type snake-proof covers fixed on the guy wires.

[0003] As disclosed in the application number 201820998020.6, the utility model includes a support member and a cylinder, wherein the support member is fixedly mounted on the tension wire, and the cylinder is rotatably mounted on the support member. Through the arrangement of the utility model, when a snake climbs onto the cylinder, the cylinder will rotate, causing the snake to continuously rotate left and right on the cylinder, and eventually causing the snake to fall without a foothold. However, the electric pole tension wire anti-snake device is difficult to appropriately extend the entire device according to different protection length requirements. The length of the device is relatively fixed, which makes it inconvenient to use, resulting in poor adaptability and inflexible use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a pole wire anti-snake device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a snake-proof device for a pole wire to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snake-proof device for electric pole wire pulling, comprising a sleeve, a mounting plate is provided below the sleeve, soft sleeve holes are provided at corresponding positions in the middle of the upper and lower ends of the sleeve and in the middle of the surface of the mounting plate, the upper end of the sleeve and the upper surface of the mounting plate are both fixedly installed with fixing rings located outside the soft sleeve holes, four positioning holes are evenly distributed on the surface of the fixing ring, and the lower end of the sleeve is fixedly installed with a connecting mechanism located outside the soft sleeve hole.

[0007] Preferably, the connecting mechanism includes an insert ring fixedly installed at the lower end of the sleeve, the diameter of the insert ring matches the inner diameter of the fixed ring, and four grooves are evenly distributed around the surface of the insert ring.

[0008] Preferably, the connecting mechanism further comprises a spring fixedly mounted on the inner surface of the groove, an insert block fixedly mounted on the end of the spring, and a lower surface of the insert block is configured as an inclined surface.

[0009] Preferably, a covering cylinder is rotatably provided on the outer surface of the sleeve, and balls are evenly distributed and rotatably embedded on the outer surface of the covering cylinder.

[0010] Preferably, the outer surface of the coating tube is provided with air holes evenly distributed between each group of balls, and the inner surface of the sleeve is provided with through cavities on both the left and right sides.

[0011] Preferably, the air hole can communicate with the interior of the sleeve via a through cavity.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a mounting plate, a fixing ring, a positioning hole, a soft sleeve hole, a connecting mechanism, an inserting ring, a groove, a spring and an inserting block. The mounting plate is fixed to the surface of the cable, the cable passes through the soft sleeve hole of the sleeve, so that the sleeve covers the surface of the cable, the sleeve is inserted into the fixing ring by means of the inserting ring, and the side wall of the fixing ring pushes the inserting block to retract into the groove through the inclined surface. When the inserting ring is fully inserted into the fixing ring, the inserting block is aligned with the positioning hole and inserted into the positioning hole under the action of the spring, thereby fixing the mounting plate and the sleeve, so that the sleeve stably covers the surface of the cable for protection, and the sleeve can be flexibly assembled and extended for use according to the required covering length of the cable using the same fixing ring and connecting mechanism, thereby greatly improving the flexibility and adaptability of the entire device.

[0014] 2. The utility model arranges the covering tube, balls, air holes and through cavity. The covering tube itself can rotate on the surface of the sleeve, cooperating with the rotation of the balls themselves to achieve double rotation, thereby greatly weakening the friction of the snake climbing on the outer surface of the sleeve, causing the snake to lose its effective force point when climbing, effectively preventing the snake from climbing onto the power equipment through the pull wire, and reducing the occurrence of line short circuit. The through cavity and air holes can ensure the air permeability and heat dissipation capacity inside the sleeve, preventing the pull wire from overheating and short circuiting, and the through cavity also greatly reduces the material used in the sleeve, thereby reducing the overall weight of the equipment and reducing the burden on the pull wire.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1-4 As shown, a snake-proof device for an electric pole wire is provided, comprising a sleeve 1, a mounting plate 2 being provided below the sleeve 1, soft sleeve holes 5 being provided at corresponding positions in the middle of the upper and lower ends of the sleeve 1 and in the middle of the surface of the mounting plate 2, a fixing ring 3 being fixedly installed on the upper end of the sleeve 1 and the upper surface of the mounting plate 2, located outside the soft sleeve hole 5, and four positioning holes 4 being evenly distributed on the surface of the fixing ring 3, and a connecting mechanism 6 being fixedly installed on the lower end of the sleeve 1 outside the soft sleeve hole 5.

[0022] By adopting the above technical solution, the soft sleeve hole 5 allows the pull wire to pass through the installation plate 2 and the sleeve 1, so that the entire device can be installed in a sheathed manner;

[0023] The connecting mechanism 6 is plugged in with the fixing ring 3 and matched with the positioning hole 4 so that the mounting plate 2 and the sleeve 1 can be installed and the sleeve 1 can be extended and spliced.

[0024] Furthermore, the connecting mechanism 6 includes an insert ring 601 fixedly mounted at the lower end of the sleeve 1. The diameter of the insert ring 601 matches the inner diameter of the fixing ring 3. Four grooves 602 are evenly distributed around the surface of the insert ring 601.

[0025] The connecting mechanism 6 further includes a spring 603 fixedly mounted on the inner surface of the groove 602 , an insert block 604 fixedly mounted on the end of the spring 603 , and a lower surface of the insert block 604 is configured as an inclined surface.

[0026] By adopting the above technical solution, the sleeve 1 is inserted into the fixing ring 3 using the insert ring 601, and the side wall of the fixing ring 3 pushes the insert block 604 to shrink into the groove 602 through the inclined surface. When the insert ring 601 is fully inserted into the fixing ring 3, the insert block 604 is aligned with the positioning hole 4 and is inserted into the positioning hole 4 under the action of the spring 603, thereby fixing the mounting plate 2 and the sleeve 1; the sleeve 1 can use the same fixing ring 3 and connecting mechanism 6, and can be flexibly assembled and extended for use according to the required covering length of the pull wire.

[0027] Furthermore, a covering cylinder 7 is rotatably provided on the outer surface of the sleeve 1 , and balls 8 are evenly distributed and rotatably embedded on the outer surface of the covering cylinder 7 .

[0028] By adopting the above technical solution, the covering tube 7 itself can rotate on the surface of the sleeve 1, cooperating with the rotation of the ball 8 itself to achieve double rotation, thereby greatly reducing the friction of the snake climbing on the outer surface of the sleeve 1, causing the snake to lose its effective force point when climbing, and effectively preventing the snake from climbing onto the electrical equipment through the pull wire.

[0029] Furthermore, the outer surface of the covering tube 7 is evenly distributed with air holes 9 between each group of balls 8, and the inner surface of the sleeve 1 is provided with through cavities 10 on both sides; the air holes 9 can be connected to the interior of the sleeve 1 through the through cavities 10.

[0030] By adopting the above technical solution, the through cavity 10 and the air hole 9 can ensure the air permeability and heat dissipation capacity inside the sleeve 1, preventing the pull wire from overheating and short circuiting, and the through cavity 10 also greatly reduces the material used in the sleeve 1, thereby reducing the overall weight of the equipment and reducing the burden on the pull wire.

[0031] Working principle: When using the electric pole wire anti-snake device, first, the mounting plate 2 is fixed on the wire surface, and the wire passes through the soft sleeve hole 5 of the sleeve 1, so that the sleeve 1 is covered on the wire surface, and the sleeve 1 is inserted into the fixing ring 3 using the insert ring 601. The side wall of the fixing ring 3 pushes the insert block 604 to shrink into the groove 602 through the inclined surface. When the insert ring 601 is fully inserted into the fixing ring 3, the insert block 604 is aligned with the positioning hole 4 and inserted into the positioning hole 4 under the action of the spring 603, thereby fixing the mounting plate 2 and the sleeve 1, so that the sleeve 1 is stably covered on the wire surface for protection, and the sleeve 1 can use the same fixing ring 3 and connecting mechanism 6, according to the wire surface. The required covering length of the wire can be flexibly assembled and extended for use. The covering tube 7 itself can rotate on the surface of the sleeve 1, and cooperate with the rotation of the ball 8 itself to achieve double rotation, thereby greatly weakening the friction of the snake climbing on the outer surface of the sleeve 1, causing the snake to lose its effective force point when climbing, effectively preventing the snake from climbing onto the power equipment through the pull wire, and reducing the occurrence of line short circuit. The through cavity 10 and the air hole 9 can ensure the air permeability and heat dissipation capacity inside the sleeve 1 to prevent the pull wire from overheating and short circuit, and the through cavity 10 also greatly reduces the material used in the sleeve 1, thereby reducing the overall weight of the equipment and reducing the burden on the pull wire. This is the working principle of the electric pole pull wire anti-snake device.
