Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figures 1 to 4 As shown, this embodiment provides a power line anti-derailment device, including an insulating column 1. The upper end of the insulating column 1 is provided with a placement groove 10, in which a circuit wire 2 is placed. An installation component 3 is sleeved on the outer wall of the insulating column 1. Anti-derailment components 4 are provided at both ends of the installation component 3. The anti-derailment component 4 includes an installation plate 41. A fixing rod 42 is fixedly installed inside the installation plate 41. A first sleeve 43 and a second sleeve 44 are rotatably installed inside the fixing rod 42. Two return springs 48 are provided on the outer wall of the installation plate 41, and one end of the return spring 48 is set on the first sleeve 43 and the second sleeve 44.
[0026] like Figure 4As shown, a protrusion 45 is fixedly connected to one end of the first sleeve 43 and the second sleeve 44. The protrusion 45 inside the second sleeve 44 is located inside the protrusion 45 at one end of the first sleeve 43. Both sets of protrusions 45 are rotatably mounted on the fixed rod 42. The protrusions 45 are the same size. A movable groove 46 is opened inside the mounting plate 41. The first sleeve 43 and the second sleeve 44 are rotatably mounted inside the movable groove 46. The circuit wire 2 is adapted to the internal dimensions of the first sleeve 43 and the second sleeve 44. Guide plates 47 are fixedly connected to the outer walls of the first sleeve 43 and the second sleeve 44. The outer walls of the two guide plates 47 are connected to the return spring 48. The other end of the return spring 48 is fixedly connected to the outer wall of the mounting plate 41.
[0027] By pressing the circuit wire 2 into the first sleeve 43 and the second sleeve 44 on both sides, the first sleeve 43 and the second sleeve 44 are subjected to pressure while the circuit wire 2 is being pressed, causing the protrusions 45 at both ends to rotate and be limited by the fixed rod 42. At the same time, the guide plate 47 presses the return spring 48 to cooperate. When the circuit wire 2 is pressed into the two sleeves, the first sleeve 43 and the second sleeve 44 rebound under the pressure of the return spring 48 and engage the circuit wire 2. The distance between the two ends of the first sleeve 43 and the second sleeve 44 is smaller than the diameter of the circuit wire 2. The circuit wire 2 needs to be pressed into the two sleeves for easy placement and is suitable for circuit wires 2 of different sizes. The first sleeve 43 and the second sleeve 44 are both made of stainless steel.
[0028] like Figures 2 to 3 As shown, the mounting assembly 3 includes a mounting bracket 31. The middle part of the mounting bracket 31 is set in a semi-circular ring shape. The middle part of the mounting bracket 31 is adapted to the upper end of the insulating column 1. Two mounting plates 41 are fixedly connected to both ends of the mounting bracket 31. The upper end of the insulating column 1 is provided with a mounting groove 35. The bottom of the mounting bracket 31 is fixedly connected with a snap-fit block 32. The snap-fit block 32 is adapted to the size of the mounting groove 35. A threaded knob 33 is provided on the outside of the mounting bracket 31. A threaded rod 34 is fixedly connected to the outer wall of the threaded knob 33. The outer wall of the threaded rod 34 is threadedly connected to the inside of the mounting bracket 31 and the extended end is connected to the inside of the insulating column 1 to avoid problems such as the circuit wire 2 falling off.
[0029] By passing the circuit wire 2 through the slot 10 on the insulating post 1, the operator uses the snap-fit block 32 to snap the mounting bracket 31 into the mounting slot 35 on the insulating post 1, so that the mounting bracket 31 fits against the outside of the insulating post 1. At this time, the operator rotates the threaded knob 33 to drive the threaded rod 34 to rotate, and fixes the mounting bracket 31 on the insulating post 1. When it is necessary to disassemble, replace or maintain, the mounting bracket can be removed.
[0030] The working principle and process of this utility model are as follows: First, the insulating posts 1 are installed on utility poles. The circuit wires 2 are passed through the mounting slots 10 on the insulating posts 1. The operator uses the snap-fit block 32 to snap the mounting bracket 31 into the mounting slots 35 on the insulating posts 1, making the mounting bracket 31 fit against the outside of the insulating posts 1. Then, the operator rotates the threaded knob 33 to rotate the threaded rod 34, fixing the mounting bracket 31 onto the insulating posts 1. Disassembly, replacement, or maintenance is relatively convenient. After the mounting bracket 31 is fixed, it allows the circuit wires 2 to be placed on both sides of the pole. The circuit wire 2 is squeezed into the first sleeve 43 and the second sleeve 44. While the circuit wire 2 is being squeezed, the first sleeve 43 and the second sleeve 44 are subjected to pressure, which causes the protrusions 45 at both ends to rotate and be limited by the fixed rod 42. At the same time, the two sleeves rotate and are squeezed by the guide plate 47 to cooperate with the return spring 48. When the circuit wire 2 is squeezed into the two sleeves, the first sleeve 43 and the second sleeve 44 rebound under the pressure of the return spring 48 and engage with the circuit wire 2. This makes it easy to limit and fix the circuit wire 2 of different sizes and avoid problems such as falling off after long-term use.
[0031] The technical solution of this utility model is not limited to the specific embodiments described above. Any technical modifications made according to the technical solution of this utility model shall fall within the protection scope of this utility model.
