Description

Technical Field

[0001] This invention belongs to the field of cable equipment technology, specifically a parallel bundled overhead insulated cable. Background Technology

[0002] Parallel bundled overhead insulated cables use three-phase four-wire power supply, which minimizes the imbalance of the three-phase load of the distribution transformer, reduces the neutral current, and thus reduces resistance loss. The parallel bundled conductors reduce the number of poles, crossarms, and porcelain components, saving a lot of metal. Due to insulation, the height of the poles can be reduced, and it is not affected by complex environments such as trees and building complexes. It can be laid along the wall, completely eliminating the need for poles, and the project cost is low.

[0003] However, in the existing technology, the connection area between the conductors of the existing parallel bundled overhead insulated cable is large, which makes it more susceptible to environmental conditions during overhead use. This leads to a shorter service life for the parallel bundled overhead insulated cable, increases the stress area of ​​the parallel bundled overhead insulated cable, and consequently increases the requirements for the support equipment of the existing parallel bundled overhead insulated cable, resulting in poor actual performance of the existing parallel bundled overhead insulated cable. Summary of the Invention

[0004] The purpose of this invention is to provide a parallel bundled overhead insulated cable that can ensure the actual service life of the cable body and reduce the impact of the usage environment on the cable body.

[0005] The technical solution adopted in this invention is as follows: a parallel bundled overhead insulated cable, comprising: a cable body;

[0006] A connecting mechanism, wherein the connecting mechanism is disposed on the cable body; and

[0007] A support mechanism is provided on the connecting mechanism, and the support mechanism is used to cooperate with the connecting mechanism to limit and support the adjacent cable body.

[0008] The cable body has multiple sets of connecting grooves equidistantly formed on its outer surface, with four connecting grooves in each set. The cable body also has multiple support grooves equidistantly formed on its outer surface along the circumferential direction.

[0009] The connecting mechanism is provided in two sets. Each set of the connecting mechanism includes a first connecting plate and four connecting strips. The four connecting strips are fixedly connected to the outer surface of one side of the first connecting plate.

[0010] The eight connecting strips are divided into four groups, with two connecting strips in each group inserted into the corresponding connecting slots, and two locking blocks passing through the outer surfaces of the two connecting strips in each group.

[0011] Each of the first connecting plates has two first connecting blocks fixedly connected to its top, and each of the first connecting plates has two first fixing holes on its top.

[0012] The support mechanism includes a first support frame, a second support frame, two second connecting plates, and two sets of extension components. The first support frame has a first mounting hole and a second mounting hole at both ends, and the second support frame also has a first mounting hole and a second mounting hole at both ends. A first connecting shaft is rotatably connected between the two first mounting holes, and a second connecting shaft is rotatably connected between the two second mounting holes. Two rotating tubes are rotatably connected to the outer surface of the second connecting shafts. The two second connecting plates are respectively sleeved on the outer surface of the corresponding rotating tubes. The two sets of extension components are respectively disposed on the first support frame and the second support frame.

[0013] Each of the second connecting plates has two first connecting holes on its outer surface. The inner wall of each first connecting hole is in contact with the outer surface of the corresponding first connecting block. Each of the second connecting plates has two second fixing holes on its outer surface. Each second fixing hole has a first fixing block that slides through it. The four first fixing blocks are divided into two groups. A first frame is slidably engaged between the outer surfaces of the two first fixing blocks in each group. Each first frame has two first mounting openings on one side of its outer surface. Each first frame has a first limiting rod threadedly connected to the other side of its outer surface. One end of each first limiting rod slides through the corresponding two first fixing blocks, and one end of each of the two first fixing blocks slides through the first fixing hole.

[0014] The first and second support frames each have two second connecting holes on their outer surfaces, and two third fixing holes on their outer surfaces. Each third fixing hole has a second fixing block that slides through it. The four second fixing blocks are divided into two groups. A second frame is slidably engaged between the outer surfaces of the two second fixing blocks in each group. Each second frame has two second mounting openings on one side of its outer surface, and a second limiting rod is threaded onto the other side of its outer surface. One end of each second limiting rod slides through the corresponding two second fixing blocks.

[0015] Each set of extension components includes an extension frame. The outer surface of the extension frame has two fourth fixing holes. The inner wall of each fourth fixing hole is in contact with the outer surface of the corresponding second fixing block. Two second connecting blocks are fixedly connected to the outer surface of the extension frame. One end of each second connecting block extends into the interior of the corresponding second connecting hole. A support rod passes through the other outer surface of the extension frame. Multiple heat dissipation ceramic tubes are equidistantly slidably sleeved on the outer surface of the support rod.

[0016] In this configuration, one end of each extension frame extends into the interior of the corresponding support groove, and the outer surface of each heat dissipation ceramic tube is in contact with the inner wall of the corresponding support groove.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] (1) In this invention, during use, the connecting mechanism can be quickly and securely connected to the cable body through the connecting groove by means of the card block and the connecting strip. Then, the first connecting plate and the second connecting plate can be quickly connected by means of the first fixing hole and the second fixing hole in conjunction with the first fixing block. At the same time, the first card frame can be quickly fitted between one end of the corresponding two first fixing blocks through the first mounting port. Then, the position of the corresponding first fixing block can be quickly fixed and restricted by the first limiting rod. Then, the first connecting plate and the corresponding second connecting plate can be securely connected. Then, one end of the extension frame is extended into the corresponding support groove, so that the first support frame and the second support frame can change the use angle with the adjacent cable body through the extension frame and the corresponding support groove. This facilitates the adjustment of the use angle between the adjacent cables and the installation of the cable body. At the same time, the gap between the first support frame and the second support frame can effectively reduce the stress area of ​​the cable body, thereby effectively reducing the support requirements of the existing cable support equipment and facilitating the installation of the cable body.

[0019] (2) In this invention, the support groove can cooperate with the extension frame to enable the first support frame and the second support frame to support and restrict the adjacent cable bodies. At the same time, the support groove can increase the heat dissipation area of ​​the cable body. With the cooperation of the heat dissipation ceramic tube, the cable body can efficiently dissipate the heat generated during operation, thereby effectively extending the actual service life of the cable body. In the case of snowfall, the gap between the first support frame and the second support frame can reduce the accumulation of snowfall. At the same time, the efficiently dissipated heat can effectively prevent the accumulation of snowfall and ice on the surface of the cable body. The support of the first support frame and the second support frame can more stably maintain the use angle between adjacent cable bodies, so that the cable body can be erected and used more stably. At the same time, the second fixing block, the third fixing hole and the fourth fixing hole can facilitate the separation and connection of the extension frame, the first support frame and the second support frame, thereby facilitating the adjustment of the cable body placement position and improving the actual erection efficiency. At the same time, the connecting mechanism and the second connecting plate can quickly and stably connect adjacent cable bodies. At the same time, the cable bodies can be connected or separated according to the actual erection and use requirements, improving the convenience of actual use of the equipment.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] For examples, please refer to [link / reference]. Figure 1 and Figure 2 A parallel bundled overhead insulated cable consists of a cable body 1, a connecting mechanism 2, and a supporting mechanism 3.

[0032] The details are as follows:

[0033] Please see Figure 3 Multiple sets of connecting grooves 102 are equidistantly provided on the outer surface of the cable body 1, and four connecting grooves 102 are provided in each set. Multiple support grooves 101 are equidistantly provided on the outer surface of the cable body 1 along the circumferential direction.

[0034] Please see Figure 4 and Figure 5 The connecting mechanism 2 is mounted on the cable body 1. There are two sets of connecting mechanisms 2. Each set includes a first connecting plate 201 and four connecting strips 202. The four connecting strips 202 are fixedly connected to the outer surface of one side of the first connecting plate 201. The eight connecting strips 202 are divided into four groups. Two connecting strips 202 in each group are inserted into the corresponding connecting groove 102. Two locking blocks 203 pass through the outer surfaces of the two connecting strips 202 in each group. Two first connecting blocks 205 are fixedly connected to the top of each first connecting plate 201. Two first fixing holes 204 are opened on the top of each first connecting plate 201. Through the locking blocks 203 and connecting strips 202, the connecting mechanism 2 can be quickly and securely connected to the cable body 1 via the connecting groove 102, and then connected via the first fixing holes 204 and the second connecting blocks 205. The fixing hole 318, in conjunction with the first fixing block 315, enables the quick connection of the first connecting plate 201 and the second connecting plate 313. Simultaneously, through the first mounting port, the first clip frame 316 can be quickly fitted between one end of the corresponding two first fixing blocks 315. Then, through the first limiting rod 317, the position of the corresponding first fixing block 315 can be quickly fixed and restricted, thereby enabling the first connecting plate 201 and the corresponding second connecting plate 313 to be securely connected. Furthermore, one end of the extension frame 303 extends into the interior of the corresponding support groove 101, allowing the first support frame 301 and the second support frame 319 to change their operating angles along with the adjacent cable body 1 through the extension frame 303 and the corresponding support groove 101. This facilitates the adjustment of the operating angle between adjacent cables and the installation and erection of the cable body 1.

[0035] Please see Figures 6-9The support mechanism 3 is mounted on the connecting mechanism 2. The support mechanism 3 is used to cooperate with the connecting mechanism 2 to limit and support the adjacent cable body 1. The support mechanism 3 includes a first support frame 301, a second support frame 319, two second connecting plates 313, and two sets of extension components. The first support frame 301 has a first mounting hole and a second mounting hole at both ends, and the second support frame 319 also has a first mounting hole and a second mounting hole at both ends. A first connecting shaft 302 is rotatably connected between the two first mounting holes, and a second connecting shaft 311 is rotatably connected between the two second mounting holes. Two rotating tubes 312 are rotatably connected to the outer surface of the second connecting shafts 311. The two second connecting plates 313 are respectively sleeved on the outer surface of the corresponding rotating tubes 312. The two sets of extension components... Each second connecting plate 313 is respectively mounted on the first support frame 301 and the second support frame 319. Each second connecting plate 313 has two first connecting holes 314 on its outer surface. The inner wall of each first connecting hole 314 fits against the outer surface of the corresponding first connecting block 205. Each second connecting plate 313 has two second fixing holes 318 on its outer surface. A first fixing block 315 slides through the interior of each second fixing hole 318. The four first fixing blocks 315 are divided into two groups. A first locking frame 316 is slidably engaged between the outer surfaces of the two first fixing blocks 315 in each group. Each first locking frame 316 has two first mounting openings on one side of its outer surface. A first limiting rod 317 is threadedly connected to the other side of each first locking frame 316. Each first limiting rod... One end of each of the two first fixing blocks 315 slides through the first fixing hole 204. Two second connecting holes 307 are provided on the outer surfaces of the first support frame 301 and the second support frame 319. Two third fixing holes are provided on the outer surfaces of both the first support frame 301 and the second support frame 319. A second fixing block 308 slides through the interior of each third fixing hole. The four second fixing blocks 308 are divided into two groups. A second locking frame 309 is slidably engaged between the outer surfaces of the two second fixing blocks 308 in each group. Two second mounting openings are provided on one side of the outer surface of each second locking frame 309. A second limiting rod 310 is threadedly connected to the other side of the outer surface of each second locking frame 309. Two limiting rods 310 each slide through one end of their respective second fixing blocks 308. Each set of extension components includes an extension frame 303. The outer surface of the extension frame 303 has two fourth fixing holes. The inner wall of each fourth fixing hole is in contact with the outer surface of the corresponding second fixing block 308. Two second connecting blocks 306 are fixedly connected to the outer surface of the extension frame 303. One end of each second connecting block 306 extends into the interior of the corresponding second connecting hole 307. Support rods 304 pass through the outer surface of the other side of the extension frame 303. Multiple heat dissipation ceramic tubes 305 are equidistantly slidably mounted on the outer surface of the support rods 304. One end of each extension frame 303 extends into the interior of the corresponding support groove 101. The outer surface of each heat dissipation ceramic tube 305 is in contact with the inner wall of the corresponding support groove 101.The gap between the first support frame 301 and the second support frame 319 effectively reduces the stress area of ​​the cable body 1, thereby reducing the support requirements for existing cable support equipment and facilitating the installation of the cable body 1. Simultaneously, the support groove 101, in conjunction with the extension frame 303, allows the first support frame 301 and the second support frame 319 to provide support and restraint between adjacent cable bodies 1. Furthermore, the support groove 101 increases the heat dissipation area of ​​the cable body 1, and with the cooperation of the heat dissipation ceramic tube 305, the cable body 1 can efficiently dissipate the heat generated during operation, thus effectively extending the actual service life of the cable body 1. Additionally, in snowy conditions, the gap between the first support frame 301 and the second support frame 319 reduces snow accumulation and facilitates efficient heat dissipation. The heat effectively prevents snow and ice buildup on the surface of the cable body 1. Simultaneously, the support from the first support frame 301 and the second support frame 319 more stably maintains the operating angle between adjacent cable bodies 1, allowing for more stable installation. Furthermore, the second fixing block 308, the third fixing hole, and the fourth fixing hole facilitate the easy separation and connection of the extension frame 303, the first support frame 301, and the second support frame 319, thereby facilitating the adjustment of the cable body 1's placement position and improving actual installation efficiency. Additionally, the connecting mechanism 2 and the second connecting plate 313 enable quick and secure connection between adjacent cable bodies 1, allowing for connection or separation of the cable bodies 1 according to actual installation and usage requirements, thus improving the ease of use of the equipment.

[0036] In use, the connecting mechanism 2 can be quickly and securely connected to the cable body 1 via the connecting groove 102 through the locking block 203 and the connecting strip 202. Then, the first connecting plate 201 and the second connecting plate 313 can be quickly connected through the first fixing hole 204 and the second fixing hole 318 in conjunction with the first fixing block 315. Simultaneously, the first mounting port allows the first locking frame 316 to be quickly fitted between one end of the corresponding two first fixing blocks 315. The first limiting rod 317 then quickly and securely restricts the position of the corresponding first fixing block 315, thereby ensuring a stable connection between the first connecting plate 201 and the corresponding second connecting plate 313. The extension frame 303 is then extended at one end into the corresponding support groove 101, allowing the first support frame 301 and the second support frame 319 to change their operating angles along with the adjacent cable body 1 via the extension frame 303 and the corresponding support groove 101. This facilitates adjustment of the operating angles between adjacent cables and makes it easier to install and erect the cable body 1. Simultaneously, the gap between the first support frame 301 and the second support frame 319 effectively reduces the stress area of ​​the cable body 1, thereby reducing the support requirements for existing cable support equipment and facilitating the erection of the cable body 1. Furthermore, the support groove 101 can cooperate with the extension frame 301. 03 The first support frame 301 and the second support frame 319 can provide support and restriction between adjacent cable bodies 1. Simultaneously, the support groove 101 increases the heat dissipation area of ​​the cable body 1. With the cooperation of the heat dissipation ceramic tube 305, the cable body 1 can efficiently dissipate the heat generated during operation, thereby effectively extending the actual service life of the cable body 1. Furthermore, in snowy conditions, the gap between the first support frame 301 and the second support frame 319 can reduce snow accumulation, and the efficiently dissipated heat can effectively prevent snow and ice buildup on the surface of the cable body 1. Meanwhile, the support of the first support frame 301 and the second support frame 319... The support can more stably maintain the operating angle between adjacent cable bodies 1, allowing the cable bodies 1 to be erected and used more stably. At the same time, the second fixing block 308, the third fixing hole and the fourth fixing hole can facilitate the separation and connection of the extension frame 303, the first support frame 301 and the second support frame 319, thereby facilitating the adjustment of the placement position of the cable bodies 1 and improving the actual erection efficiency. Meanwhile, the connecting mechanism 2 and the second connecting plate 313 can quickly and stably connect adjacent cable bodies 1, and can connect or separate the cable bodies 1 according to the actual erection and use requirements, improving the convenience of actual use of the equipment.
