[0002] The inclined wire is mostly used at the terminal of the line tower. In order to offset the pulling force of the wire on the last pole and ensure that the last pole does not tilt too much, an inclined fixed wire is added in the opposite direction of the wire to balance the force of the pole. In the operation of the distribution network, foreign objects often climb along the inclined wire, such as climbing vines and small animals (snakes, mice) that come with them. When small animals climb along the inclined wire to a certain height, it is very easy to cause short circuit or grounding of power equipment and other faults, thereby causing power supply failures. In severe cases, human electric shock accidents may occur. At present, staff members are required to regularly patrol to clean up foreign objects on the inclined wire, but it is difficult for patrol personnel to drive away foreign objects in real time and efficiently.

[0028] See also Figure 1 , an embodiment of an anti-climbing inclined cable protection device provided in the present application includes: a protective cover and an anti-falling fastener 4;
[0029] The protective cover can be rotatably mounted on the outside of the oblique cable 2; the anti-falling fastener 4 is arranged on the oblique cable 2 by bolts; the protective cover is provided with a support frame 3, the support frame 3 includes a first support frame and a second support frame, the first support frame abuts against the upper side of the anti-falling fastener 4, so that the protective cover rotates around the oblique cable 2 when subjected to external force; the anti-falling fastener 4 is used to support the protective cover through the first support frame.
[0030] It can be understood that the anti-drop fastener 4 is tightly wrapped around the inclined wire 2 by bolts to achieve tight fixation. At the same time, the anti-drop fastener 4 supports the protective cover through the first support frame to prevent the protective cover from slipping into it. The support frame 3 is preferably a straight support frame, and the support frame is an assembled structure;
[0031] The present embodiment provides a protective device with a simple structure and light weight. The device is installed on the inclined wire 2 in the electric power industry. When a foreign object climbs up the inclined wire 2 to the protective cover, the protective cover is acted upon by the foreign object. At this time, the protective cover rotates along the inclined wire 2 as the axis and then throws off the foreign object, so as to prevent the foreign object from climbing up the inclined wire 2, reduce the work intensity of the operation and maintenance personnel, and better protect the safe and stable operation of the power grid system.
[0032] In a specific embodiment, the protective sleeve includes a guide tube 6 and a bell mouth 1 fixedly arranged at the bottom of the guide tube 6 .
[0033] It can be understood that the bell mouth 1 is used to guide foreign objects to climb into the protective cover, and can ensure that the foreign objects climbing upwards can smoothly enter the protective cover along the inclined wire.
[0034] In a specific embodiment, both sides of the support frame 3 are connected to the guide tube 6 ; a ring-shaped member is provided in the middle of each support frame 3 , and the ring-shaped member is wound around the outside of the inclined cable 2 .
[0035] In a specific embodiment, the annular member of the first supporting frame is rotatably disposed on the top of the anti-drop fastener 4 .
[0036] It should be noted that due to the gravity of the protective cover, the annular part of the first support frame is in close contact with the anti-falling fastener 4, and then the protective cover is supported by the anti-falling fastener 4. The protective cover is protected by the supporting force of the anti-falling fastener 4 to prevent the protective cover from sliding along the inclined cable 2.
[0037] In a specific embodiment, a connecting member 5 is further included; the connecting member 5 is detachably connected to the supporting frame 3 .
[0038] Specifically, the connecting member 5 is detachably connected to each supporting frame 3 on the outer side of the guide tube 6; the connecting member 5 is preferably a bolt.
[0039] Please refer to 2, Figure 2The cross-sectional view of the protection device is a concentric annular structure, including a support frame 3, an anti-drop fastener 4, a guide tube 6, a bell mouth 1 and a cross-sectional circle center whose axis is the inclined wire 2; wherein each support frame 3 has a portion protruding outside the guide tube 6, and the protection device is assembled and fixed at the protruding portion with bolts, wherein the bolts are Figure 2 The shaded part of the image.
[0040] In a specific embodiment, the protective cover is in the shape of a long trumpet and is a spliced structure.
[0041] It can be understood that the protective cover is a splicing structure. In actual installation, the protective cover can be assembled on the inclined wire 2 through the connecting piece 5; the splicing structure is convenient for the inspection personnel to disassemble and carry, and also convenient for the inspection personnel to carry out cleaning work.
[0042] In a specific embodiment, the material of the protective cover is preferably PVC material, and the friction coefficient of the surface of the protective cover is small; the guide tube 6 is preferably made of transparent material, and the bell mouth 1 is preferably made of yellow material.
[0043] The protective device provided in this embodiment can also prevent vines from climbing along the inclined wire 2. It is understandable that the growth rate of vines is very rapid, and the inspection frequency of inspectors can hardly keep up with the growth of vines, so the plants need to be removed. The guide tube 6 of this device is made of transparent material, and the trumpet mouth 1 is made of opaque yellow material. If the plants climb along the inclined wire, the sun-loving characteristics of the plants can be utilized to attract the plants to grow into the protective cover. At the same time, the guide tube 6 is a transparent PVC tube and the shape of the protective cover is a long trumpet, which can gather light and heat to cause the plants to scorch and wither, thereby inhibiting the growth of the plants.
[0044] It should be noted that vine plants are burned by heat accumulation only when they climb into the guide tube 6 area, thereby inhibiting the growth of plants; it can be understood that for climbing plants, the protection device provided in this embodiment can only scorch plants in the guide tube to inhibit the growth of plants in the protective cover, so that the plants grow away from the protective cover, thereby preventing the plants from climbing the oblique line; in this embodiment, scorching and withering refers to reducing the moisture of the plants in the guide tube 6 area, thereby inhibiting the growth of the plants in the guide tube 6 area to a certain extent, so that the plants grow away from the protective cover, thereby preventing the plants from climbing the oblique line 2. At the same time, in actual applications, in order to further improve the safety performance of the protection device, the PVC material used in the protective cover needs to be added with heat-resistant or flame-retardant materials.
[0045] In a specific embodiment, the bottom of the bell mouth 1 is preferably a circle with a diameter of 280 mm, the bell mouth 1 converges inward at 45°, and the convergence height of the bell mouth 1 is 90 mm.
[0046] In a specific embodiment, the bottom diameter of the guide tube 6 is preferably 100 mm, the top diameter of the guide tube 6 is preferably 30 mm, and the length of the guide tube 6 is preferably 510 mm.
[0047] In a specific embodiment, see Figure 3 The annular width of the annular part of the support frame 3 is preferably 6 mm, and the annular width of the anti-falling fastener 4 is preferably 8 mm.
[0048] It is understandable that the inner diameter of the annular member of the support frame 3 needs to be slightly larger than the outer diameter of the inclined wire 2 to achieve unimpeded rotation of the protective sleeve along the inclined wire 2; it should be noted that Figure 3 The shaded part of the annular member of the middle support frame 3 is the cross section of the connecting member 5. Figure 3 The shaded portion of the anti-drop fastener 4 is the cross section of the bolt.
[0049] The working process of the protection device provided by the present application is as follows: when plants climb along the inclined wire 2, since the guide tube 6 is made of transparent material and the trumpet mouth 1 is made of yellow material, the sunlight has a sun-oriented effect on the vine plants, so the sunlight passes through the guide tube 6 to attract the plants to grow toward the inside of the protective cover. As the plants continue to extend, the space inside the protective cover becomes smaller, and the transparent PVC material and the long trumpet-shaped structure have the effect of focusing light and heat, causing the plants to burn and wither, thereby inhibiting the growth of the plants; when small animals climb the inclined wire 2, since the surface of the protective cover is smooth, when the small animals climb to the protective cover, they cannot exert force on the surface of the protective cover after contacting the surface of the protective cover. At the same time, the protective cover rotates when it is contacted by the external force of the small animal, and the climbing small animal is thrown off, thereby preventing the small animal from climbing.
[0050] An embodiment of the present application provides an anti-climbing oblique cable protection device, comprising: a protective cover, an anti-falling fastener and a connecting piece, the protective cover comprising a guide tube and a bell mouth fixedly arranged at the bottom of the guide tube; the protective cover can be rotatably mounted on the outside of the oblique cable; the anti-falling fastener is arranged around the oblique cable by bolts; the protective cover is provided with a support frame, the support frame comprises a first support frame and a second support frame, the first support frame abuts against the upper side of the anti-falling fastener, so that the protective cover rotates around the oblique cable when subjected to external force; the anti-falling fastener is used to support the protective cover through the first support frame.
[0051] The device is installed on the inclined cable of the power industry. Its main body is in the shape of a long trumpet. The large trumpet mouth at the end can ensure that the plants growing upwards can smoothly enter the interior of the device along the cable. As the plants continue to grow in the device, the internal space of the protective device becomes smaller. The guide tube is a transparent PVC tube. The sunlight from the transparent material has a sun-facing effect on the vines. The long trumpet shape and transparent PVC material have the effect of gathering light and heat, causing the vines to scorch and wither, thereby inhibiting plant growth. The protective cover can be rotated along the inclined cable as the axis through the support frame, and the surface of the protective cover is smooth, so small animals cannot exert force on its surface, thereby preventing small animals from climbing the cable. The device can effectively prevent foreign objects from climbing along the inclined cable, reduce the work intensity of operation and inspection personnel, and better protect the safe and stable operation of the power grid system.
[0052] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
