Description

Technical Field

[0001] This disclosure relates to the field of insulating crossarm technology, and more particularly to a 380V composite insulating crossarm. Background Technology

[0002] Composite insulated crossarms are a type of support structure used in power transmission lines. They primarily provide insulation and mechanical properties. They typically consist of a core rod and an insulating outer sleeve. Common cross-sectional shapes of the core rod include solid square, T-shaped, triangular, and L-shaped, ensuring reliable mechanical and electrical performance. The insulating outer sleeve is generally made of high-temperature vulcanized silicone rubber produced from fumed silica, which has excellent insulation and aging resistance.

[0003] Most existing insulated crossarms are directly fixed to utility poles and their installation angle cannot be adjusted. They cannot be well adapted to actual needs that require inclined installation, which limits their applicability. Furthermore, after installation, the long horizontal structure usually has a small load-bearing capacity, making it unsuitable for supporting heavy or multiple cables. The small load-bearing capacity can also easily lead to damage to the crossarm, affecting its safety in use. Summary of the Invention

[0014] Optionally, the auxiliary support structure further includes: a pressure block, a second sliding groove is provided in the rotating groove, the second sliding groove is connected to the rotating plate groove, the pressure block is slidably fitted in the second sliding groove, and a plurality of second springs are fixed between the pressure block and the second sliding groove; wherein, when the pressing block presses the pressure block, the pressure block slides downward and causes one end of the support plate to be subjected to downward pressure, so that the other end of the support plate rotates through the second rotating shaft to form a support lever structure, which can provide better support for the crossbeam body.

[0015] Optionally, the combined structure includes: a combination frame, which corresponds to the connecting block, and the combination frame is provided with a plurality of second through slots, which correspond to the positioning slots; wherein, when it is necessary to connect two outer cores together, the connecting block on one outer core is inserted into the combination frame on the other outer core, the second through slot is aligned with the positioning slot and a double-ended screw is inserted, and then fixed by the double-ended screw and nut.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. During installation, the installation angle of the crossarm body can be adjusted by rotating the connecting structure. This allows for adjustment of the installation angle of the crossarm body according to actual needs, making the installation and use of the crossarm body more flexible, expanding the applicability of the device, and allowing for adjustment of the position of the support structure and umbrella sleeve as needed, thereby ensuring the crossarm body's support effect on the cable and ensuring the insulation performance of the crossarm body.

[0017] 2. After installation, with the angle fixed, the crossarm body can be supported by an auxiliary support structure. Multiple crossarm bodies can also be combined to adjust the length of the crossarm body.

This ensures that the crossarm body can support heavier cables and multiple cables, thus ensuring the safety of the crossarm and expanding the application range of the crossarm body.

[0018] 3. During installation, the position of the support structure can be freely combined and adjusted, so that the support structure can better support the cable and ensure that the support structure can effectively support the cable, preventing the support structure from not contacting the cable due to cable misalignment.

[0021] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 11 As shown in the figure, this disclosure proposes a 380V composite insulated crossarm, comprising: an installation structure including a first clamp 101, on which a fixed connection structure is mounted; a crossarm body, the surface of which is coated with nanomaterials, the crossarm body including an inner core 201 and an outer core 202, the outer core 202 having multiple umbrella sleeves 203, a spacing structure and a support structure mounted on its periphery, the support structure corresponding to the fixed connection structure, and a combined structure mounted at one end of the crossarm body; and a rotating connection structure corresponding to the fixed connection structure, which connects the installation structure and the crossarm body together, the fixed connection structure having an auxiliary support structure mounted on it, the rotating connection structure driving the auxiliary support structure to support the crossarm body when connected to the fixed connection structure, the lower crossarm body tilting upwards and being connected to and supported by the rotating connection structure and the combined structure.

[0023] In this embodiment, the installation structure further includes: a plurality of first fixing bolts 102, the first fixing bolts 102 corresponding to the two ends of the first clamp 101, the first clamp 101 being clamped and fixed to the utility pole by the first fixing bolts 102, the first clamp 101 being fixed with a mounting base 103, and the fixed connection structure and auxiliary support structure being installed in the mounting base 103.

[0024] Specifically, when the first clamp 101 needs to be installed, the first clamp 101 is put on the utility pole, and then the first clamp 101 is tightened by the first fixing bolt 102, thereby clamping and fixing the first clamp 101 to the utility pole, which can provide a foundation for supporting the crossarm body. The position of fixing the first clamp 101 can be selected as needed, making the installation of the device more flexible and expanding the application range of the device.

[0025] The crossarm body also includes: multiple umbrella sleeves 203, each umbrella sleeve 203 including an umbrella skirt 204 and a connecting sleeve 205. The umbrella skirt 204 is located on the periphery of the connecting sleeve 205 and is fixedly connected to the connecting sleeve 205. The connecting sleeve 205 corresponds to the outer core 202. The spacing structure includes multiple auxiliary spacers 206, which are located between two adjacent connecting sleeves 205 to fill the gap between the two connecting sleeves 205. When the support structure is installed, the multiple support structures are fixed on the outer core 202 and limit the connecting sleeves 205 and the auxiliary spacers 206. The connecting sleeves 205 and the auxiliary spacers 206 are fixed by compression. The inner core 201 is fixed inside the outer core 202 and is a hollow hexagonal star structure.

[0026] Specifically, the hollow inner core 201 reduces the overall weight of the device and lowers the production cost of the inner core 201. Furthermore, the hexagonal star structure provides good support, ensuring the strength of the crossarm. The outer core 202, made of insulating material and coated with nanomaterials, ensures the insulation effect of the device, thereby guaranteeing its safe use and supporting 380V cables. Both the connecting sleeve 205 and the auxiliary spacer 206 are clamped and fixed after installation using the second clamp 301. Therefore, before installing the second clamp 301, the number of connecting sleeves 205 and auxiliary spacers 206 can be selectively chosen according to actual needs, and the position of the connecting sleeves 205 can be adjusted, making the device more flexible in use and expanding its applicability.

[0027] The support structure includes: a second clamp 301, which corresponds to the outer core 202, and also corresponds to the connecting sleeve 205 and the auxiliary spacer 206. Multiple second fixing bolts 302 are installed at the end of the second clamp 301, and the second clamp 301 is clamped and fixed to the outer core 202 by the multiple second fixing bolts 302. A support base 303 is fixed to the second clamp 301, and a clamping seat 305 is installed on the support base 303. Multiple first screws 306 are installed on the clamping seat 305, and multiple first screw grooves 307 are formed inside the support base 303. The first screw 306 corresponds to the first screw groove 307. The support base 303 has a first groove 304, and the clamping base 305 has a second groove 308, with the first groove 304 and the second groove 308 corresponding to each other. When placing a cable, the clamping base 305 is installed on the support base 303 by the first screw 306 to clamp and fix the cable. The support structure located on the side of the crossarm body near the first clamp 101 has its first groove 304 and second groove 308 combined to form a through groove structure, through which a pull rope or pull rod is connected to the fixed connection structure.

[0028] Specifically, when the second clamp 301 needs to be installed, the second clamp 301 is placed on the outer core 202, and then the second clamp 301 is clamped and fixed to the periphery of the outer core 202 by the second fixing bolt 302, thereby limiting the connection sleeve 205 and the auxiliary spacer 206, thus clamping and fixing the connection sleeve 205 and the auxiliary spacer 206, thereby ensuring the stability of the umbrella cover 203. After installation, the cable can be placed in the first groove 304, and then the clamping seat 305 is covered, so that the cable is located in the first groove 304 and the second groove 308. At this time, the first screw 306 is screwed in to fix the clamping seat 305 and the support seat 303, thereby achieving the clamping and fixing of the cable and ensuring the stability of the cable support.

[0029] Furthermore, the second clamp 301 located closest to the first clamp 101 has a first groove 304 and a second groove 308 on it that are not used to support cables. After installation, the first groove 304 and the second groove 308 form a through groove structure, which, together with the first through groove 501, allows the first through groove 501 and the groove structure to be used to install rigid pull ropes or pull rods. This helps to apply a certain tension to the crossarm body, improves the load-bearing strength of the crossarm body, and ensures the safety of the crossarm body. This allows the crossarm body to support more cables and expands the applicability of the device.

[0030] The rotating connection structure includes: a connecting frame 401, which is fixedly connected to the outer core 202. A first rotating shaft 402 is rotatably fitted inside the connecting frame 401. Nuts 405 are threaded onto both ends of the first rotating shaft 402. A connecting block 403 is fixed on the first rotating shaft 402. A positioning groove 404 is provided on the connecting block 403, which corresponds to the fixed connection structure. When adjusting the angle of the crossbeam body, the connecting block 403 is fixedly connected to the fixed connection structure. The first rotating shaft 402 can rotate to adjust the tilt angle of the outer core 202. After adjustment, the first rotating shaft 402 is fixed by rotating the nuts 405. The tilt angle of the outer core 202 is limited by the pull rope or pull rod connected between the groove structure and the fixed connection structure, and the auxiliary support structure, thereby enhancing the load-bearing capacity of the outer core 202.

[0031] Specifically, the connecting block 403 rotates relative to the outer core 202 via the first rotating shaft 402. With the connecting block 403 fixed, the angle of the crossarm body can be adjusted, thereby enabling the crossarm body to be installed at an angle, expanding the applicability of the device, and making the device more flexible in installation and use. After adjusting the angle, the first rotating shaft 402 can be squeezed and clamped by the nut 405 to prevent the first rotating shaft 402 from rotating. At this time, the angle of the crossarm body can be fixed, ensuring that the crossarm body can be tilted relatively stably, thereby ensuring the support effect for the cable.

[0032] The fixed connection structure includes: a first through groove 501, which is formed within the mounting base 103. The first through groove 501 is connected to the groove structure to install a pull rope or pull rod to limit and assist the support of the outer core 202; a rotating groove 502, which is formed within the mounting base 103. A slot 507 is formed within the rotating groove 502, which corresponds to the connecting block 403. A rotating plate 503 and a pressing structure are rotatably fitted within the rotating groove 502. A positioning structure is installed between 03 and the extrusion structure, and an insertion structure is installed in the rotating groove 502. The extrusion structure fixes the connecting block 403 by extruding the insertion structure. When installing, the connecting block 403 is inserted into the slot 507. Rotating the rotating plate 503 causes the extrusion structure to extrude the insertion structure into the positioning groove 404 to limit the connection block 403. Continuing to rotate the rotating plate 503 can cause the extrusion structure to extrude downwards to rotate the auxiliary support structure, thereby supporting the crossbeam body.

[0033] Specifically, when connecting the crossarm body to the first clamp 101, the connecting block 403 can be inserted into the slot 507. Then, the rotating plate 503 is manually rotated, causing the rotating plate 503 to drive the pressing block 504 to press the insert block 509, so that the insert block 509 is inserted into the positioning slot 404. This connects the connecting block 403, thus connecting and fixing the crossarm body to the first clamp 101. After the connection is completed, it is only necessary to fix the position of the pressing block 504 to ensure that the pressing block 504 is always in a pressing state on the insert block 509. This ensures that the insert block 509 can be stably inserted into the positioning slot 404, thus ensuring a stable connection effect of the connecting block 403 and the stability of the crossarm body. This allows the crossarm body to better support the cable and ensure the safe use of the device.

[0034] The extrusion structure includes an extrusion block 504, which is rotatably fitted within a rotating groove 502. The rotating groove 502 has multiple second threaded grooves 506. The extrusion block 504 is fixedly connected to a rotating plate 503. A second screw 505 is threaded onto the rotating plate 503, and the second screw 505 corresponds to the second threaded groove 506. The insertion structure includes an insertion block 509. A first sliding groove 508 is formed within the rotating groove 502, communicating with a slot 507. The first sliding groove 508 is slidably connected to the insertion block 509. Multiple first springs 510 are fixed between the first sliding groove 508 and the insertion block 509. When the extrusion block 504 is rotated, it extrudes the insertion block 509, causing it to slide within the first sliding groove 508. The first springs 510 are compressed and inserted into the positioning groove 404 to fix the connecting block 403.

[0035] Specifically, when the rotating plate 503 is rotated, it drives the pressing block 504 to rotate as well, thereby pressing the insert block 509. After pressing, the second screw 505 can be rotated to insert into the second screw groove 506, thus fixing the position of the rotating plate 503 and the pressing block 504, ensuring the pressing effect of the pressing block 504. During pressing, the pressing block 504 pushes the insert block 509 to slide in the first slide groove 508, compressing the first spring 510. When the pressing block 504 stops pressing the insert block 509, the first spring 510 rebounds and pushes the insert block 509 back to its original position, ensuring that the insert block 509 no longer limits the connection block 403, making it easy to remove the connection block 403 and making the device easier to install and remove.

[0036] The auxiliary support structure includes: a support plate 516; a rotating plate groove 514 is provided on the lower side of the rotating groove 502; a second rotating shaft 515 is rotatably fitted inside the rotating plate groove 514; a torsion spring is installed between the rotating plate groove 514 and the second rotating shaft 515; the second rotating shaft 515 is fixedly connected to the support plate 516; and the support plate 516 has an L-shaped structure. The pressing block 504, after pressing the insert block 509, can further rotate downwards to push the support plate 516 to rotate around the second rotating shaft 515, causing the support plate 516 to contact the outer core 202 and limit its movement. Furthermore, after the pressing block 504 is fixed, it can support the... The rotation angle of the support plate 516 is limited to ensure the stability of the support. The auxiliary support structure also includes a pressure block 512. A second sliding groove 511 is provided in the rotating groove 502. The second sliding groove 511 is connected to the rotating plate groove 514. The pressure block 512 is slidably fitted in the second sliding groove 511. Multiple second springs 513 are fixed between the pressure block 512 and the second sliding groove 511. When the pressing block 504 presses the pressure block 512, the pressure block 512 slides downward, causing one end of the support plate 516 to be subjected to downward pressure. This causes the other end of the support plate 516 to rotate through the second rotating shaft 515, forming a support lever structure, which can provide better support for the crossbeam body.

[0037] Specifically, when the crossarm body needs support, the pressing block 504 continues to rotate downwards on top of the pressing block 509, causing the pressing block 504 to press and push the pressure block 512 downwards. The pressure block 512 then slides within the second groove 511, and the second spring 513 is stretched. At this time, the pressure block 512 can press the support plate 516 downwards, causing the support plate 516 to rotate via the second rotating shaft 515. This brings the support plate 516 into contact with the crossarm body, providing a relatively stable support effect. Combined with the pull rod or rope to pull the crossarm body, this increases the load-bearing capacity of the crossarm body, ensuring its safety and expanding its applicability. When disassembling, the pressing block 504 resets and no longer limits the pressure block 512. The second spring 513 rebounds, causing the pressure block 512 to reset, allowing the support plate 516 to reset under the action of gravity and the torsion spring, thus enabling the device to be disassembled.

[0038] The combined structure includes: a combination frame 601, which corresponds to the connecting block 403. The combination frame 601 has multiple second through slots 602, which correspond to the positioning slots 404. When it is necessary to connect two outer cores 202 together, the connecting block 403 on one outer core 202 is inserted into the combination frame 601 on the other outer core 202. The second through slots 602 and positioning slots 404 are aligned and a double-ended screw is inserted. Then, it is fixed by the double-ended screw and nut.

[0039] Specifically, when it is necessary to combine two crossarm bodies together, the connecting block 403 on one outer core 202 is inserted into the combination frame 601 on the other outer core 202. The second through slot 602 is aligned with the positioning slot 404 and a double-ended screw is inserted. Then, it is fixed by the double-ended screw and nut, which can realize the connection of the two crossarm bodies, thereby increasing the length of the device, enabling the device to support more cables, expanding the application range of the device, and supporting the upper crossarm body by tilting the lower crossarm body upwards, further ensuring the installation strength of the crossarm body, increasing the load-bearing capacity of the crossarm body, and expanding the application range of the device.

[0040] Workflow: First clamp 101 is fitted onto the utility pole, and then tightened using the first fixing bolt 102, thus clamping and fixing the first clamp 101 onto the utility pole, providing a foundation for supporting the crossarm body. Second clamp 301 is fitted onto the outer core 202, and then clamped and fixed to the periphery of the outer core 202 using the second fixing bolt 302, thereby limiting the positioning of the connecting sleeve 205 and the auxiliary spacer 206, ensuring the stability of the umbrella sleeve 203. After installation, the cable can be placed in the first groove 304. Then, the clamping seat 305 is covered, so that the cable is located in the first groove 304 and the second groove 308. At this time, the first screw 306 is screwed in to fix the clamping seat 305 and the support seat 303, thereby achieving the clamping and fixing of the cable. The second clamp 301, located on the side closest to the first clamp 101, does not use the first groove 304 and the second groove 308 on the second clamp 301 for cable support. After installation, the first groove 304 and the second groove 308 form a through groove structure, which, together with the first through groove 501, allows the first through groove 501 and the groove structure to be used to install rigid pull ropes or pull rods, thereby assisting in the clamping and fixing of the crossarm. When a certain tension is applied to the body, the connecting block 403 rotates relative to the outer core 202 via the first rotating shaft 402. This allows for adjustment of the angle of the crossarm body while the connecting block 403 is fixed, enabling oblique installation of the crossarm body. When connecting the crossarm body to the first clamp 101, the connecting block 403 can be inserted into the slot 507. Then, the rotating plate 503 is manually rotated, causing the pressing block 504 to press the insert block 509, causing the insert block 509 to insert into the positioning slot 404. This connects the connecting block 403, thus connecting and fixing the crossarm body to the first clamp 101. After the connection is complete... Afterwards, simply fixing the position of the extrusion block 504 ensures that the extrusion block 504 is always in a state of extruding the insertion block 509, thus ensuring that the insertion block 509 can be stably inserted into the positioning groove 404. When the rotating plate 503 is rotated, the rotating plate 503 will drive the extrusion block 504 to rotate together, thereby extruding the insertion block 509. After extrusion is completed, the second screw 505 can be rotated to insert the second screw groove 506, thereby fixing the position of the rotating plate 503 through the second screw 505, thus fixing the position of the extrusion block 504 and ensuring the extrusion effect of the extrusion block 504.During compression, the compression block 504 pushes the insert block 509, causing it to slide within the first groove 508. The first spring 510 is compressed. When the compression block 504 stops compressing the insert block 509, the first spring 510 rebounds, pushing the insert block 509 back to its original position. This ensures that the insert block 509 no longer limits the connection block 403, facilitating its removal. When support for the crossarm body is required, the compression block 504 continues to rotate downwards while still compressing the insert block 509. This causes the compression block 504 to press down on the pressure block 512, causing it to slide within the second groove 511. The second spring 513 is stretched, allowing the pressure block 512 to press down on the support plate 516. This causes the support plate 516 to rotate via the second rotating shaft 515, bringing it into contact with the crossarm body and providing stable support.
