Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology, and in particular to an integrated windproof insulation protection device for power lines that allows for live-line operation. Background Technology

[0002] Electricity is the main energy source in modern society. Electricity is generated by power generation devices and transmitted through high-voltage lines. Multiple high-voltage towers are built on the ground to support the high-voltage lines that transmit electricity, which is then transmitted to various places to provide power for motors.

[0003] Electricity is transmitted using conductors. When the conductors are installed on high-voltage towers, they are fixed with insulators to isolate the electricity on the line and prevent the electricity from being conducted from the high-voltage tower to the ground, which would cause danger and waste electricity. At the same time, power protection devices are used to prevent the electricity from dissipating and to isolate the current.

[0004] Existing protective devices require screws or wrapping to be fixed when installed on lines, which is not only time-consuming and requires tools, increasing the labor intensity of workers, but also has low protective effect. Under strong current, the protective device may be damaged and cause explosion risk. To solve the above problems, a live-line windproof integrated insulation protection device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated windproof insulation protection device for live-line work, which aims to improve the problems of inconvenient, time-consuming and labor-intensive installation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A live-line windproof integrated insulation protection device includes a main body, a connecting body installed at the bottom of the main body, an upper end body fixedly connected to the top of the main body, a lower pressure cover fixedly connected to the top of the upper end body, a rotating component installed on one side of the lower pressure cover, an upper pressure cover fixedly connected to the other side of the rotating component, and an adjusting component installed on one side of the fixed component.

[0008] The adjustment assembly includes a second fixed rod, which is fixedly connected to one side of the upper pressure cover. A second rotating rod is rotatably connected inside the second fixed rod. A fixed sleeve is fixedly connected to the middle of the second rotating rod. A first fixed rod is fixedly connected to one side of the lower pressure cover. A first rotating rod is rotatably connected to the middle of the first fixed rod. A threaded sleeve is fixedly connected to the middle of the first rotating rod. A bolt is threaded inside the threaded sleeve. A rotating block is fixed to the other end of the bolt. The rotating block is rotatably connected inside the fixed sleeve.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a hinge, which is fixedly connected to one side of the lower pressure cover, and the other side of the hinge is fixedly connected to one side of the upper pressure cover;

[0011] As a further description of the above technical solution:

[0012] An arc-inducing rod is fixedly connected to one side of the lower pressure cover, and an arc-receiving rod is fixedly connected to one side of the main body;

[0013] As a further description of the above technical solution:

[0014] A second rainproof plate is fixedly connected to the outside of the upper body, and a first rainproof plate is fixedly connected to the outside of the main body;

[0015] As a further description of the above technical solution:

[0016] A fixing block is fixedly connected to one side of the main body, a connecting rope is fixedly connected to one end of the fixing block, and the other end of the connecting rope is fixedly connected to one side of the connecting body.

[0017] As a further description of the above technical solution:

[0018] The bottom of the connector is threaded with multiple nuts, which are located on one side of the connecting rope.

[0019] As a further description of the above technical solution:

[0020] A resistor is installed inside the main body, and a connector is fixedly connected to the other end of the resistor.

[0021] As a further description of the above technical solution:

[0022] A knob is fixedly connected to one end of the bolt.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the hinged design of the rotating component allows for flexible opening and closing of the pressure cap while the wire is energized, avoiding the limitations of traditional binding methods that require power disconnection. Simultaneously, the use of a second fixing rod, a second rotating rod, a threaded sleeve, and bolts, through the threaded linkage between the bolts and the threaded sleeve, enables precise opening and closing adjustment of the upper and lower pressure caps. During operation, the operator can quickly adapt to different wire diameters by rotating the knob without disassembly or power interruption, significantly reducing installation time.

[0025] 2. In this utility model, an umbrella-skirt structure is adopted to cover the main body and the upper body, effectively isolating rainwater from intrusion and reducing the risk of flashover of insulating components due to moisture. The arc-starting rod and the arc-receiving rod form a gap for isolation, which works in conjunction with the resistor to discharge lightning current (current carrying capacity 100kA). The rain shield design simultaneously suppresses wind-polarized motion, and the connecting body is fixed with a connecting rope so that if the resistor is broken down, the connecting body will fall off and be fixed with the connecting rope. This not only allows people to notice it in time, but also prevents the connecting body from falling off. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model provides: a live-line windproof integrated insulation protection device, including a main body 1, a connecting body 3 installed at the bottom of the main body 1, an upper end body 6 fixedly connected to the top of the main body 1, the main body 1, the upper end body 6 and the connecting body 3 together constitute a protective device, a lower pressure cover 7 fixedly connected to the top of the upper end body 6, a rotating component installed on one side of the lower pressure cover 7, and an upper pressure cover 8 fixedly connected to the other side of the rotating component. The device is fixed to the conductor by the upper pressure cover 8 and the lower pressure cover 7, and an adjustment component is installed on one side of the fixing component.

[0035] The adjustment assembly includes a second fixed rod 13, which is fixedly connected to one side of the upper pressure cover 8. A second rotating rod 18 is rotatably connected inside the second fixed rod 13. A fixed sleeve 23 is fixedly connected to the middle of the second rotating rod 18. The second rotating rod 18 drives the fixed sleeve 23 to rotate inside the second fixed rod 13. A first fixed rod 9 is fixedly connected to one side of the lower pressure cover 7. A first rotating rod 14 is rotatably connected to the middle of the first fixed rod 9. A threaded sleeve 20 is fixedly connected to the middle of the first rotating rod 14. The first rotating rod 14 rotates inside the threaded sleeve 20 within the first fixed rod 9. A bolt 15 is threadedly connected inside the threaded sleeve 20. A rotating block 19 is fixed to the other end of the bolt 15. The bolt 15 rotates inside the threaded sleeve 20, and its other end is supported by the rotating block 19 and rotates inside the fixed sleeve 23. The rotating block 19 is rotatably connected inside the fixed sleeve 23. A knob 16 is fixedly connected to one end of the bolt 15. An adjustment assembly is installed at the top. Through the threaded engagement of bolt 15 and threaded sleeve 20, rotating rod 14 and rotating rod 28 are driven in tandem to achieve the opening and closing adjustment of the upper pressure cover 8 and the lower pressure cover 7. Knob 16 is designed for manual operation and can be adjusted according to the diameter range of the wire, allowing for tightening without disassembly.

[0036] Reference Figure 1 and Figure 2 The fixing components include hinges 17, which are fixedly connected to one side of the lower pressure cover 7 and the other side of the upper pressure cover 8. The rotating assembly formed by the hinges 17 allows the pressure cover to rotate around an axis, facilitating quick installation of the wire while it is energized, avoiding the drawback of traditional binding requiring power disconnection. An arc-initiating rod 12 is fixedly connected to one side of the lower pressure cover 7, and an arc-receiving rod 11 is fixedly connected to one side of the main body 1. The arc-initiating rod 12 and the arc-receiving rod 11 form a discharge gap, which, together with the resistor 21, discharges the lightning current (capable of withstanding 100kA). The connecting rope 10 and the fixing block 22 limit the wind deflection of the wire. A second rainproof plate 5 is fixedly connected to the outside of the upper body 6, and a first rainproof plate 2 is fixedly connected to the outside of the main body 1. The first rainproof plate 2 and the second rainproof plate 5 adopt an umbrella skirt structure, covering the main body 1 and the upper body 6 to form a rainproof barrier and effectively suppress wet flashover.

[0037] Reference Figure 2 , Figure 4A fixing block 22 is fixedly connected to one side of the main body 1. A connecting rope 10 is fixedly connected to one end of the fixing block 22, and the other end of the connecting rope 10 is fixedly connected to one side of the connecting body 3. The connecting rope 10 provides protection for the connecting body 3. Multiple nuts 4 are threadedly connected to the bottom of the connecting body 3, and the multiple nuts 4 are located on one side of the connecting rope 10. A resistor 21 is installed inside the main body 1. The other end of the resistor 21 is fixedly connected to the connecting body 3. The threaded connection between the nuts 4 and the connecting body 3 provides mechanical locking to prevent the connecting body 3 from falling off. The built-in design of the resistor 21 avoids external aging and extends the life of the device.

[0038] Working principle: First, place the cable inside the groove above the lower cover 7, rotate the knob 16, which drives the bolt 15 to rotate. The bolt 15 rotates inside the threaded sleeve 20, moving its position. The other end of the bolt 15 rotates inside the fixing sleeve 23, simultaneously pressing the fixing rod 13. The fixing rod 13 drives the upper cover 8 to rotate. The upper cover 8 rotates on one side of the lower cover 7 using the hinge 17, closing the upper cover 8 and the lower cover 7, thus fixing them to the cable. It is simple and convenient.

[0039] Secondly, the arc-starting rod 12 and the arc-receiving rod 11 are designed to be separate to isolate the conduction of current. At the same time, a resistor 21 is set inside the main body 1 to fix the connector 3. When the current is too large and the resistor 21 is broken down, the connector 3 can fall off and be noticed in time. Meanwhile, a connecting rope 10 is fixed on the fixing block 22 on one side of the main body 1 to fix the connector 3 and prevent it from falling off. Multiple rain shields 2 are installed on the outside of the main body 1 to block rainwater when it rains and extend the service life.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
