Description

Technical Field

[0001] This invention relates to the field of electromagnetic shielding component manufacturing technology, and more specifically, to an electromagnetic shielding type power system iron accessory and its installation structure. Background Technology

[0002] Power line accessories are key metal components used in power systems to support, fix, and connect conductors and electrical equipment. They are typically made of steel or cast iron, possessing high strength and corrosion resistance. They encompass various types, including crossarms of transmission towers, insulator fittings, cable supports, clamps, and ferrules, and are widely used in substation structures, transmission lines, and distribution equipment. For example, crossarms are used to fix conductors and maintain safe spacing, while tension clamps transmit conductor tension through mechanical clamping. These accessories must meet stringent standards, such as tensile strength, conductivity, and weather resistance, to ensure stable load bearing in complex climates and long-term operation. They are fundamental components for ensuring the safe and reliable operation of the power grid.

[0003] The installation of traditional power system metal fittings relies on a large number of bolts for fixing. Operators must screw in each bolt one by one and calibrate its position, a tedious and time-consuming process. Especially at heights or in complex environments, tightening and loosening bolts becomes even more difficult, significantly reducing installation efficiency. Furthermore, bolts exposed to long-term outdoor conditions are susceptible to creep or thread wear due to temperature changes, vibration, and electromagnetic interference, leading to loose connections. Loose connections require regular maintenance and tightening; otherwise, poor contact, equipment damage, or even safety accidents may occur, increasing maintenance costs and risks.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an electromagnetically shielded power system iron accessory and its installation structure. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an electromagnetically shielded power system iron accessory and its installation structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electromagnetically shielded power system installation structure, including a grid crossarm, and further comprising:

[0007] Insertion pieces are provided at both ends of the scissor fork mechanism, and mounting hardware is also provided on the scissor fork mechanism through an adjusting component. The adjusting component is used to bring the two insertion pieces on the scissor fork mechanism closer to each other and insert them into the crossarm, thereby realizing the initial installation action of the mounting hardware.

[0008] A clamping mechanism is installed on the crossarm of the space frame. A clamping column is installed on the clamping mechanism. After the connector is inserted into the crossarm, the clamping mechanism causes the clamping column to move down and abut against the surface of the mounting hardware. At the same time, after the clamping column presses down against the mounting hardware, the clamping mechanism is also used to form a rigid connection structure between the mounting hardware and the crossarm of the space frame.

[0009] Preferably, the clamping mechanism includes a trapezoidal frame mounted on the crossbeam of the space frame by a spring, and a rotating hollow column mounted at the bottom of the crossbeam of the space frame. A drive rod is provided at the bottom of the trapezoidal frame and inserted into the rotating hollow column. The rotating hollow column and the drive rod are connected by a spiral groove guide pin mechanism. The clamping column is threaded onto the outer surface of the rotating hollow column.

[0010] Preferably, the clamping mechanism further includes a limiting groove formed on the clamping column, in which a multi-purpose arc-shaped piece is inserted, and the end of the multi-purpose arc-shaped piece is fixed to the bottom surface of the grid crossbeam. After the clamping column moves downward and abuts against the surface of the hardware mounting bracket, the multi-purpose arc-shaped piece separates from the limiting groove.

[0011] Preferably, the multi-purpose arc-shaped piece has a groove, and the surface of the groove is provided with a diffusion spring through an elastic element.

[0012] Preferably, a guide block is also provided on the top surface inside the crossbeam of the space frame, and an inclined surface is provided on the guide block, and the inclination of the inclined surface is greater than the inclination of the inclined section of the trapezoidal frame.

[0013] Preferably, the connector includes push plates mounted on the two ends of the top side of the scissor fork mechanism. The push plates are provided with mounting blocks. After the mounting blocks are inserted into the crossbeam of the space frame by the scissor fork mechanism, the mounting blocks simultaneously abut against the surfaces of the guide block and the trapezoidal frame.

[0014] Preferably, a wedge block is also installed on the crossarm of the space frame via positioning pins. Multiple positioning pins are provided, with two adjacent positioning pins forming a group. Each group of positioning pins forms a hardware installation station. A positioning rotating plate is also installed on the mounting block via a one-way shaft.

[0015] Preferably, after the multi-purpose arc-shaped piece separates from the limiting groove, the mounting block abuts against the inclined surface of the trapezoidal frame.

[0016] Preferably, the crossarm and fitting mounting bracket are made of electromagnetically shielded material.

[0017] An electromagnetically shielded power system iron accessory, comprising any of the electromagnetically shielded power system installation structures described above.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The electromagnetic shielding power system installation structure of the present invention achieves boltless and rapid installation of mounting hardware through the synergistic action of a scissor fork mechanism and a clamping mechanism. Specifically, the scissor fork mechanism drives the two end connectors to approach each other and insert into the crossarm through an adjusting component, completing the initial fixing of the mounting hardware; subsequently, the clamping mechanism abuts against the surface of the mounting hardware by moving the clamping column downward, forming a stable connection. The entire installation process does not require the use of bolts and can be completed simply by hanging, greatly simplifying the installation process and improving installation efficiency.

[0020] 2. Although the installation structure of this invention does not use bolts for fixing, the downward pressing action of the clamping column on the installation hardware and the rigid connection structure formed between the installation hardware and the grid crossarm by the clamping mechanism ensure the stability of the installation. This design effectively prevents loosening caused by long-term outdoor environmental influences. Its tightness is even better than the traditional bolt installation method, which significantly improves the stability and safety of the power system.

[0021] 3. The clamping mechanism of this invention cleverly incorporates a multi-purpose arc-shaped piece, which plays multiple roles during installation. In the initial stage of the clamping column's downward movement, the multi-purpose arc-shaped piece inserts into the limiting groove of the clamping column, providing a limiting function. Once the clamping column is firmly against the installation hardware, the multi-purpose arc-shaped piece separates from the limiting groove and abuts against the top surface of the clamping column, forming part of a rigid connection, thus enhancing the stability of the overall structure. Furthermore, the diffusion spring design on the multi-purpose arc-shaped piece expands the contact area, further improving the strength of the rigid structure.

[0022] 4. This invention creates a clear hardware installation station by setting positioning pins and wedge blocks on the crossarm of the space frame. During installation, the operator only needs to place the installation block roughly in the positioning area, push the installation block upwards, and use the inclined surface of the wedge block to guide it to quickly and accurately position the installation block in the correct position. At the same time, the positioning plate on the installation block automatically returns to a horizontal state and overlaps with the positioning pin after passing the wedge block, further confirming the accuracy of the installation position. This design greatly simplifies the installation positioning process and improves installation efficiency. Attached Figure Description

[0034] like Figure 1-9 As shown, the present invention provides an electromagnetic shielding power system installation structure, including a grid crossarm 1, which is installed on a pole. Whether the installation uses clamps or bolts depends on the on-site construction conditions and is existing technology, so it will not be described in detail here.

[0035] When the mounting hardware 2 is installed on the crossarm, the electromagnetic shielded power system installation structure also includes plug-in parts installed at both ends of the scissor fork mechanism. The scissor fork mechanism is also equipped with mounting hardware 2 through an adjusting part. The adjusting part is used to bring the two plug-in parts on the scissor fork mechanism closer to each other and insert them into the crossarm, so as to realize the initial installation action of mounting hardware 2. The scissor fork mechanism can change its angle so that the plug-in parts located at the top of the scissor fork mechanism are brought closer to each other and inserted into the grid crossarm 1. At this time, the initial installation of mounting hardware 2 can be completed, so that it is initially fixed on the grid crossarm.

[0036] To enhance the stability of the mounting hardware 2, a clamping mechanism is provided on the crossbeam 1 of the space frame. A clamping column 17 is installed on the clamping mechanism. After the connector is inserted into the crossbeam, the clamping mechanism causes the clamping column 17 to move downwards and abut against the surface of the mounting hardware 2. This ensures that the mounting hardware 2 is clamped downwards by the clamping column 17 after the connector is inserted into the crossbeam 1. At this time, the angle of the scissor fork mechanism is fixed, preventing loosening of the scissor fork structure due to external factors in the outdoor environment, thus preventing the connector from detaching from the crossbeam 1. Simultaneously, after the clamping column 17 clamps the mounting hardware 2 downwards, the clamping mechanism also forms a rigid connection between the mounting hardware 2 and the crossbeam 1. This rigid connection further improves the stability of the scissor fork mechanism, further prevents changes in the angle of the scissor fork mechanism, and can prevent most of the influence of the external environment.

[0037] The entire installation process does not require the use of a large number of bolts to fix the mounting hardware 2. Instead, the mounting hardware 2 can be fixed to the crossbeam 1 of the space frame directly by hanging. This allows a rigid connection to be formed between the crossbeam 1 of the space frame and the surface of the mounting hardware 2. Compared with the use of bolts, which may loosen over a long period of time, this hanging installation method not only greatly reduces the difficulty of installation (no need to screw in a large number of bolts), but also provides a stronger tightness in the long-term outdoor environment than using bolts, greatly improving the installation effect of the mounting hardware 2.

[0038] In one embodiment of the present invention, the scissor fork mechanism consists of a rotating frame 5 and a rotating frame 6 that are rotatably connected by a shaft. The plug-in is installed on the ends of the rotating frame 5 and the rotating frame 6 respectively. The angle between the rotating frame 5 and the rotating frame 6 can be changed by the adjustment component. It should be noted that in another embodiment of the present invention, the adjustment component includes a positive and negative screw 12. Two sliders 11 are threaded on the positive and negative screw 12. The two sliders 11 are rotatably disposed on the bottom surfaces of the rotating frame 5 and the rotating frame 6 respectively. The mounting hardware 2 is disposed on the two sliders 11. By turning the positive and negative screw 12, the two sliders 11 can be moved closer or further away from each other, thereby changing the angle of the scissor fork structure formed by the rotating frame 5 and the rotating frame 6, so that the plug-in located on the top side can be inserted into the crossbeam 1 of the grid frame.

[0039] In one embodiment of the present invention, the clamping mechanism includes a trapezoidal frame 9 mounted on the crossbeam 1 of the space frame via a spring 14, and a rotating hollow column 13 mounted at the bottom of the crossbeam 1. A drive rod 8 is provided at the bottom of the trapezoidal frame 9 and inserted into the rotating hollow column 13. The rotating hollow column 13 and the drive rod 8 are connected by a spiral groove guide pin mechanism. The clamping column 17 is threaded onto the outer surface of the rotating hollow column 13. When the connector is inserted into the crossbeam 1, it abuts against the trapezoidal frame 9. At this time, the spring 14 contracts and deforms, and the trapezoidal frame 9 moves downward within the crossbeam 1, thereby causing the drive rod 8 to move downward. Since the drive rod 8 and the rotating hollow column 13 are connected by a spiral groove guide pin mechanism, the clamping mechanism is further strengthened by the spring 14. The spiral groove guide pin mechanism is used for connection. When the drive rod 8 moves downward, a relative displacement occurs between the drive rod 8 and the rotating hollow column 13. The spiral groove guide pin mechanism can make the rotating hollow column 13 rotate, which allows the clamping column 17 to move downward on the rotating hollow column 13 until the clamping column 17 abuts against the surface of the mounting hardware 2. At this time, the clamping column 17 clamps the mounting hardware 2. The top of the scissor fork mechanism is inserted into the crossbeam 1 of the grid frame through the plug-in connector, and the mounting hardware 2 in the lower part is clamped by the clamping column 17. At this time, the angle of the scissor fork mechanism will no longer change, and the installation of the mounting hardware 2 is in a relatively firm state.

[0040] In another embodiment of the present invention, a guide block 7 is further provided on the top surface inside the crossbeam 1 of the space frame. The guide block 7 is provided with an inclined surface, and the inclination of the inclined surface is greater than the inclination of the inclined section of the trapezoidal frame 9. The plug-in component includes a push plate 3 installed on the two ends of the top side of the scissor fork mechanism. The push plate 3 is provided with a mounting block 10. After the mounting block 10 is inserted into the crossbeam 1 of the space frame through the scissor fork mechanism, the mounting block 10 simultaneously abuts against the surfaces of the guide block 7 and the trapezoidal frame 9. By turning the positive and negative screws 12, the scissor fork mechanism is engaged. When adjusting the angle of the fork structure, the push plate 3 pushes the mounting block 10 so that the mounting block 10 is inserted into the crossbeam 1 of the space frame. At the same time, the mounting block 10 abuts against the surfaces of the guide block 7 and the trapezoidal frame 9. Then, the positive and negative screws 12 are rotated, and the mounting block 10 continues to move into the crossbeam 1 of the space frame. Since the inclination of the inclined surface is greater than the inclination of the inclined section of the trapezoidal frame 9, under the action of the guide block 7, the mounting block 10 will gradually squeeze the trapezoidal frame 9, thereby causing the trapezoidal frame 9 to move downward and the drive rod 8 to move downward.

[0041] It is important to note that the purpose of adjusting the angle of the scissor fork mechanism by designing the positive and negative lead screws 12 is to ensure that the angle change of the scissor fork structure is gradual and slow. Furthermore, by gradually pressing the trapezoidal frame 9 downwards through the guide block 7, it is possible to prevent the trapezoidal frame 9 from descending prematurely due to the inability to accurately control the manual force when directly pulling down the scissor fork mechanism or manually adjusting its angle. This would result in the trapezoidal frame 9 moving to its maximum stroke before the mounting block 10 has entered the maximum stroke within the crossbeam 1 of the space frame. At this point, the mounting block 10 is still in the inclined section of the trapezoidal block. Even if the clamping column 17 presses down against the hardware mounting frame, it will not be able to be installed securely, and may even cause the lower part of the scissor fork structure to fall off due to pressure.

[0042] The guide block 7 and adjusting component here eliminate the influence of human force on the trapezoidal frame 9. The angle of the scissor fork mechanism is gradually changed by the adjusting component, and the guide block 7 gradually pushes the mounting block 10 downward, thereby gradually moving the trapezoidal frame 9 downward. When the mounting block 10 is inserted into the end of the inclined section of the trapezoidal frame 9 (the straight section near the top of the trapezoidal frame 9), the clamping column 17 presses down to tighten the mounting hardware 2. At this time, the mounting block 10 has been inserted into a certain depth in the crossbeam 1 of the space frame, so there will be no problem of insecure installation or falling off. This prevents problems during the installation process and improves the installation effect.

[0043] In order to further improve the installation firmness of the mounting hardware 2, in another embodiment of the present invention, the clamping mechanism further includes a limiting groove 18 formed on the clamping column 17. A multi-purpose arc-shaped piece is inserted into the limiting groove 18, and the end of the multi-purpose arc-shaped piece is fixed to the bottom surface of the grid crossbeam 1. After the clamping column 17 moves downward and abuts against the surface of the hardware mounting frame, the multi-purpose arc-shaped piece separates from the limiting groove 18. The multi-purpose arc-shaped piece has a groove, and the surface of the groove is provided with a diffusion spring through an elastic element.

[0044] During the process of inserting the mounting block 10 into the crossbeam 1 of the space frame through the adjusting component, the mounting block 10 gradually presses the trapezoidal frame 9 downward through the guide block 7, thereby causing the clamping column 17 to gradually move downward. When the clamping column 17 touches the mounting hardware 2 downward, the mounting block 10 is in the inclined section near the top straight section of the trapezoidal frame 9. At this time, if the positive and negative threads are continued to be turned, the rotating hollow column 13 will also rotate. At this time, the trapezoidal frame 9 moves downward to its maximum stroke. However, due to the multi-purpose arc plate and the limiting groove 18 After separation, the mounting block 10 abuts against the inclined surface of the trapezoidal frame 9. The separation of the arc-shaped piece from the limiting groove 18 causes the clamping column 17 to no longer have a limiting function. That is, after the clamping column 17 abuts against the surface of the mounting hardware 2, the trapezoidal frame 9 will still move downward a certain distance under the action of the mounting block 10, which means that the rotating hollow column 13 will still rotate a certain angle. However, at this time, the clamping column 17 is no longer limited and will only move and rotate with the rotating hollow column 13, and will not continue to move downward. The limiting groove 18 on the clamping column 17 can rotate relative to the multi-purpose arc plate 16. At this time, the multi-purpose arc plate 16 and the limiting groove 18 are intersected. The multi-purpose arc plate 16 abuts against the top surface of the clamping column 17. Thus, a rod-like structure is formed between the multi-purpose arc plate 16 and the clamping column 17, and it is located between the hardware mounting frame and the space frame crossbeam 1. At this time, the mounting block 10 is located at the straight section position on the top side of the trapezoidal frame 9, and the upper surface of the mounting block 10 abuts against the surface of the guide block 7. The surface of the mounting hardware 2 of the lower half of the scissor fork mechanism forms a rigid connection structure directly with the space frame crossbeam 1, fixing the angle of the scissor fork mechanism so that it will not change due to external influences. The rigid connection is undoubtedly more robust than the problem of bolts loosening after a long time outdoors. The mounting hardware 2 can be installed by hanging, without the need for the complicated installation of bolts, providing a more robust installation method than bolts. Moreover, the overall structure is simple and suitable for widespread use.

[0045] The multi-purpose arc plate 16 not only provides a limit to the clamping column 17 when it descends, but also allows the clamping column 17 to form a rigid connection with the mounting hardware 2 after it is clamped. This gives the multi-purpose arc plate 16 multiple uses. When the multi-purpose arc plate 16 separates from the limiting groove 18, the expansion spring 19 expands outward due to the elastic element, increasing the contact area between the multi-purpose arc plate 16 and the clamping column 17, thereby improving the strength of the rigid structure. When the mounting block 10 is at its maximum stroke position within the crossbeam 1, the push plates 3 on both sides abut against the edge of the crossbeam 1, thus preventing the problem of swaying in the horizontal direction.

[0046] To further improve the installation efficiency of the mounting hardware 2, wedge blocks 15 are also installed on the crossbeam 1 of the space frame via positioning pins 4. Multiple positioning pins 4 are provided, with two adjacent positioning pins 4 forming a group, and each group of positioning pins 4 forming a hardware installation station. A positioning rotating plate 20 is also installed on the mounting block 10 via a one-way shaft. During installation, the position can be determined according to each group of positioning pins 4, and the mounting block 10 can be pushed upwards through the gaps between each group of wedge blocks 15. When pushed upwards, the positioning rotating plate 20 rotates via the one-way shaft, and after passing the wedge blocks 15, it returns to its original position under gravity. Alternatively, a torsion spring can be used to achieve the return of the wedge blocks 15. In the horizontal position, the positioning plate 20 overlaps with the positioning pin 4. Tightening the positive and negative screws 12 allows for the installation of the mounting hardware 2. Thanks to the positioning pin 4 and wedge blocks 15, installers do not need to precisely locate the installation position. Instead, they simply place the mounting blocks 10 on both sides in the approximate position and push upwards. One side of the wedge block 15 is inclined, and the distance between the inclined ends of the two wedge blocks 15 is greater than that of the mounting block 10. The wedge block 15 guides the mounting block 10 into place, causing the positioning plate 20 to rotate until it disengages from the wedge block 15, returning to a horizontal position and overlapping the surface of the positioning pin 4. This design further improves installation efficiency and is suitable for widespread use.

[0047] The crossarm and mounting bracket are made of electromagnetic shielding material. After installing power grid lines or power components on the mounting bracket 2, the electromagnetic shielding effect can be improved, preventing electromagnetic waves from a specific direction (such as above) from affecting the wires or power components on the mounting bracket 2.

[0048] An electromagnetically shielded power system iron accessory includes any of the above-described electromagnetically shielded power system installation structures. The installation structure of the power system iron accessory is used to install the mounting hardware 2 onto the grid crossarm 1.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
