Description

Technical Field

[0001] The invention relates to the technical field of power equipment protection, and in particular to an insulation protection device for a high-voltage transmission line. Background Art

[0002] As the scale of the current power system continues to expand and power equipment faces aging challenges due to long-term service, the maintenance of the insulation performance of power equipment has become one of the core elements to ensure the reliability and safety of power transmission. In order to stabilize power supply and protect people's lives and property safety, it is particularly critical and urgent to explore and implement a series of scientific and efficient protection measures.

[0003] However, the existing designs of crossing frames show significant functional limitations. Although these designs can achieve vertical height adjustment to adapt to the needs of lines of different heights, they are obviously insufficient in terms of width adjustment in the horizontal direction (i.e. left and right directions). This design defect is particularly prominent when facing complex terrain and variable line layouts, which seriously restricts the adaptability and flexibility of the crossing frame in actual application scenarios.

[0004] Specifically, in complex terrain environments such as mountainous areas and hills, high-voltage transmission lines often need to be designed with a winding layout based on the terrain characteristics. In this situation, the span frame needs to have the ability to flexibly adjust its width in the horizontal direction to closely follow the changes in the line direction. Unfortunately, most span frames currently still use a fixed-width design paradigm, which often requires frequent adjustments to the installation position or the addition of additional support structures during the actual construction process, which not only greatly increases the difficulty and cost of construction, but also poses a potential threat to the overall stability and safety of the span frame. Summary of the invention

[0031] The following descriptions of the embodiments are with reference to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented. In the description of the present invention, it should be understood that the terms "longitudinal", "length", "circumferential", "front", "rear", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0032] Please also refer to Figures 1 to 7 As shown, an embodiment of the present invention provides an insulation protection device for a high-voltage transmission line, comprising:

[0033] Install the base plate 1;

[0034] An insulating hollow cylinder 2 is fixedly mounted on the top of the mounting base plate 1, and an insulating threaded rod 3 is rotatably mounted inside the cylinder;

[0035] The mounting chamber 4 is fixedly mounted on the outer wall of the insulating hollow cylinder 2, and is provided with a first motor 5 and a transmission mechanism for driving the insulating threaded rod 3 to rotate; a second motor 11 is fixedly mounted on the inner wall of the bottom of the mounting chamber 4 away from the first motor 5, and a worm 12 is fixedly mounted on the output shaft of the second motor 11;

[0036] A wire passer 15, fixedly mounted on the top of the insulating threaded rod 3, for passing the insulating rope 17;

[0037] The rotating rod 9 is rotatably installed inside the installation bin 4, and is provided with a turbine 10 which meshes with the worm rod 12. The outer wall of the rotating rod 9 is fixedly connected to the insulating rope 17 to achieve the stretching or contraction of the insulating rope 17 in the horizontal direction.

[0038] Specifically, two rectangular blocks 8 are fixedly installed on the inner wall of the bottom of the installation bin 4, and a rotating rod 9 is rotatably installed on the side of the two rectangular blocks 8 close to each other. A turbine 10 is fixedly sleeved on the outer wall of the rotating rod 9, and the turbine 10 is meshed with a worm rod 12. A fixed block 14 is fixedly installed on the top of the insulating threaded rod 3, and a wire passer 15 is fixedly installed on one side of the fixed block 14. An insulating rope 17 is arranged inside the wire passer 15, and a color strip 18 is also fixedly installed on the bottom end of the insulating rope 17.

[0039] By rotating the insulating threaded rod 3, the wire passer 15 and the insulating rope 17 can be precisely adjusted in the vertical direction. At the same time, the transmission mechanism design of the rotating rod 9, the turbine 10, and the worm rod 12 allows the insulating rope 17 to be flexibly stretched or contracted in the horizontal direction, thereby meeting the protection requirements of different positions and angles of high-voltage transmission lines. This flexible adjustment capability in the up and down and left and right directions enables the device to easily cope with various complex line layouts, greatly enhancing its adaptability and practicality. In addition, by setting the color strip 18, not only the recognition of the device is increased, but also it is convenient for the operation and maintenance personnel to remotely monitor and identify the status of the device. During the inspection and maintenance of the high-voltage transmission line, the eye-catching color of the color strip 18 can quickly attract the attention of the operation and maintenance personnel, so as to promptly discover and deal with potential safety hazards.

[0040] like Figure 4 As shown, a plurality of circular grooves 101 are formed on the top of the mounting base plate 1 , and a plurality of fixing nails 16 are respectively threadedly mounted on the inner walls of the plurality of circular grooves 101 , and a knob 1603 is respectively fixedly mounted on the top of the plurality of fixing nails 16 .

[0041] The circular groove 101 is threadedly connected to the fixing nail 16, and the threaded connection has high connection strength and stability, which can ensure that the fixing nail 16 is not easy to loosen or fall off after installation. A knob 1603 is also fixedly installed on the top of the fixing nail 16, so that the user can easily control the rotation and advancement of the fixing nail 16 by rotating the knob 1603, thereby realizing precise adjustment of the fixed position of the installation base plate 1. The presence of the knob 1603 also increases the convenience of user operation, making the installation and disassembly process of the entire device simpler and faster.

[0042] like Figure 6 As shown, a first limiting ring 201 is fixedly installed on the top inner wall of the insulating hollow cylinder 2, and a second limiting ring 301 is fixedly installed on the bottom outer wall of the insulating threaded rod 3.

[0043] By fixing the second limiting ring 301 on the bottom of the insulating threaded rod 3 and cooperating with the first limiting ring 201 , effective limiting of the insulating threaded rod 3 in the vertical direction is formed.

[0044] like Figure 6As shown, the diameters of the first limiting ring 201 and the second limiting ring 301 are the same, and the diameter of the insulating hollow cylinder 2 is greater than the diameter of the first limiting ring 201 .

[0045] By setting the diameter of the insulating hollow cylinder 2 to be larger than the diameter of the first limiting ring 201, when the insulating threaded rod 3 is raised or lowered in the insulating hollow cylinder 2, its upward movement range can be limited by the first limiting ring 201 and the second limiting ring 301, thereby preventing the insulating threaded rod 3 from detaching from the insulating hollow cylinder 2.

[0046] like Figure 5 , Figure 7 As shown, a first motor 5 is fixedly mounted on the bottom inner wall of the mounting bin 4 , a first gear 6 is fixedly sleeved on the output shaft of the first motor 5 , and the first gear 6 is meshed with the second gear 7 .

[0047] The first gear 6 is fixedly sleeved on the output shaft of the first motor 5, so that the rotational power of the first motor 5 can be directly transmitted to the first gear 6, and then the power transmission and conversion are realized through the gear transmission mechanism.

[0048] like Figure 5 , Figure 7 As shown, a second motor 11 is fixedly mounted on the inner wall of the bottom of the mounting chamber 4 away from the first motor 5 , and a worm 12 is fixedly mounted on the output shaft of the second motor 11 .

[0049] By locating the second motor 11 away from the first motor 5, not only the internal space of the installation compartment 4 is effectively utilized, mutual interference between the first motor 5 and the second motor 11 during operation is avoided, and the second motor 11 is ensured to be able to operate stably and reliably, but also the worm 12 is fixedly installed on the output shaft of the second motor 11, so that the second motor 11 can realize linkage with other transmission mechanisms by driving the rotation of the worm 12.

[0050] like Figure 5 , Figure 7 As shown, an insulating threaded rod 3 is rotatably mounted on the inner wall of the insulating hollow cylinder 2 , and a second gear 7 is fixedly mounted on the top of the insulating hollow cylinder 2 , and the second gear 7 is threadedly connected to the insulating threaded rod 3 .

[0051] The second gear 7 is driven to rotate by the first motor 5, thereby driving the insulating threaded rod 3 to rise and fall in the insulating hollow cylinder 2. The rising and falling of the insulating threaded rod 3 will drive the fixing block 14, the wire passer 15, the insulating rope 17 and other components to move up and down until the required height is reached. The insulating rope 17 and the colored strips 18 will form a visible insulating barrier around the high-voltage transmission line to play a protective role.

[0052] like Figure 2 , Figure 5As shown, one end of the rotating rod 9 extends out of the installation chamber 4 , and two circular baffles 13 are fixedly sleeved on the outer wall of the rotating rod 9 . The bottom end of the insulating rope 17 is fixedly connected to the outer wall of the rotating rod 9 and is located in the middle of the two circular baffles 13 .

[0053] By fixing two circular baffles 13 on the outer wall of the rotating rod 9 , the two circular baffles 13 not only play the role of limiting and fixing, but also effectively prevent the insulating rope 17 from sliding or falling off on the rotating rod 9 .

[0054] like Figure 4 As shown, threads 1601 are provided on the top outer walls of the fixing nails 16 , and vertical grooves 1602 are provided on the bottom outer walls of the fixing nails 16 .

[0055] The screw structure enables the fixing nail 16 to move up and down. When the device needs to be fixed, the knob 1603 only needs to be rotated to drive the fixing nail 16 deep into the ground or the fixed foundation, thereby achieving the purpose of stabilizing the device. The vertical groove 1602 opened on the bottom outer wall of the fixing nail 16 not only increases the contact area between the fixing nail 16 and the soil or the fixed foundation, and improves the stability and firmness of the fixation, but also helps to release the stress of the soil or foundation material during the fixing process, so that the fixing nail 16 can be more easily inserted and fixed.

[0056] like Figures 1 to 3 As shown, a fixing frame 401 is fixedly installed on the top of the installation base plate 1 , the top of the fixing frame 401 is fixedly connected to the bottom of the installation chamber 4 , and the insulating hollow cylinder 2 passes through the fixing frame 401 and is fixedly connected to the fixing frame 401 .

[0057] The stable existence of the fixing frame 401 provides solid support for the installation chamber 4. By tightly fixing the top of the fixing frame 401 to the bottom of the installation chamber 4, the stability and reliability of the entire device structure are ensured. This design not only enhances the load-bearing capacity of the device, but also effectively prevents the device from shaking or tilting due to external forces, thereby ensuring the safety of the high-voltage transmission line.

[0058] The working principle and use process of the present invention are as follows:

[0059] Place the installation base plate 1 properly at a suitable position around the high-voltage transmission line to be protected. Then, by rotating the knob 1603, drive the fixing nail 16 to use its threaded structure to penetrate into the ground or fix the foundation until it is completely fixed, thereby ensuring that the installation base plate 1 is firmly fixed to the ground. Pass the insulating rope 17 through the wire passer 15 and firmly connect it with the rotating rod 9 to ensure that the insulating rope 17 can be stably suspended. At this time, start the first motor 5 in the installation chamber 4 to drive the first gear 6 to start rotating. The first gear 6 is tightly meshed with the second gear 7. As the second gear 7 rotates, the insulating threaded rod 3 moves up and down inside the insulating hollow cylinder 2, thereby adjusting the height of the fixing block 14 and the insulating rope 17. Start the second motor 11 in the installation chamber 4 to drive the worm 12 to rotate. The worm 12 is meshed with the turbine 10. As the turbine 10 rotates, the rotating rod 9 The rotation is realized under the constraint of the rectangular block 8. Two circular baffles 13 are fixedly sleeved on the outer wall of the rotating rod 9. The bottom end of the insulating rope 17 is fixedly connected to the outer wall of the rotating rod 9 and is located between the two circular baffles 13. As the rotating rod 9 rotates, the insulating rope 17 is stretched or contracted in the horizontal direction, thereby completing the left-right adjustment. A colored strip 18 is fixedly installed at the bottom end of the insulating rope 17 to provide a striking visual warning during the operation of the device, effectively preventing people or objects from mistakenly entering the dangerous area of ​​the high-voltage transmission line. The colored strip 18 is set to one section every two meters to ensure that even if it breaks under extreme circumstances, it will not fall onto the high-voltage line above. After the device is installed, through the coordinated operation of the first motor 5 and the second motor 11, the insulating rope 17 can be flexibly adjusted in the up and down and left and right directions to meet the protection requirements of different high-voltage transmission lines.

[0060] It can be seen from the above description that compared with the prior art, the beneficial effects brought about by the embodiments of the present invention are: the present invention realizes precise vertical and horizontal adjustment of the high-voltage transmission line protection device through the innovative design of the insulating threaded rod rotation and the turbine and worm gear transmission mechanism, which greatly improves the adaptability and protection accuracy of the device. Regardless of the complex line layout, it can provide a fitting protection barrier, effectively improving the protection efficiency and line operation safety. At the same time, the circular groove and threaded fixing nail design on the mounting base, combined with the convenient knob operation, not only ensure the stable installation and quick disassembly of the device, but also greatly improves the convenience of user operation. The present invention provides a comprehensive and efficient technical solution for the safety protection of high-voltage transmission lines, and has significant technical advantages and application value.

[0061] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
