Description

Technical Field

[0001] The utility model belongs to the field of casting wire grooves, and particularly relates to an installation structure of a cast busbar for outdoor high altitude. Background Technique

[0002] A cast busbar is an electrical product made by casting high-performance insulating resin and various inorganic minerals. It directly casts and seals the busbars, and has four functions of waterproof, fireproof, anticorrosive and explosion-proof. In modern urban construction, especially in the power transmission and distribution system, the cast busbar is widely used in the power transmission of outdoor high-altitude environments due to its good electrical performance, mechanical strength and weather resistance. However, most of the existing cast busbars can only be connected in a straight line during connection, and cannot be adjusted according to the specific terrain and building structure such as the roof of high-rise buildings and bridges, so the versatility is not high.

[0003] In the prior art, for example, the patent document with the publication number CN220457084U discloses a highly sealed assembled cast waterproof busbar. This busbar assembles and connects two busbars through a first fixing block and a second fixing block. However, this busbar can only be connected in a straight line during connection and cannot be adjusted according to the specific terrain and building structure, so the versatility is not high.

[0004] Therefore, there is an urgent need for an installation structure of a cast busbar for outdoor high altitude to solve the above problems. Summary of the Invention

[0005] Aiming at the problems in the prior art, the utility model proposes an installation structure of a cast busbar for outdoor high altitude. By means of the rotational connection between the first connection part and the second connection part, the angle between the first busbar and the second busbar is adjustable, and it can be adjusted according to the specific terrain and building structure, thereby improving the versatility of the busbar.

[0006] The utility model is realized as follows: An installation structure of a cast busbar for outdoor high altitude includes a first busbar and a second busbar. The first busbar is provided with a first connection part, the second busbar is provided with a second connection part, the second connection part is adapted to the first connection part, and the first connection part is rotationally connected to the second connection part. By means of the rotational connection between the first connection part and the second connection part, the angle between the first busbar and the second busbar is adjustable, and it can be adjusted according to the specific terrain and building structure, thereby improving the versatility of the busbar.

[0007] The first connecting portion is provided with a rotation prevention mechanism, which includes a driving handle and a rotation prevention block. The first connecting portion is provided with a rotation prevention hole adapted to the rotation prevention block. The driving handle is in transmission connection with the rotation prevention block to drive the rotation prevention block to synchronously clamp or loosen the second connecting portion in the rotation prevention hole. The rotation prevention mechanism operates the rotation prevention block through the driving handle to synchronously clamp the second connecting portion in the rotation prevention hole, thereby improving the fastening degree between the first busbar trunking and the second busbar trunking, preventing the change of the angle between the two, and improving the connection stability between the first busbar trunking and the second busbar trunking. At the same time, the clamping and loosening of the rotation prevention block can be realized through simple operation of the driving handle, which simplifies the operation process and improves the convenience of operation of the rotation prevention mechanism.

[0008] It further includes a protective cover covering the first connecting portion and the second connecting portion. The protective cover includes symmetrically arranged cover bodies and a bellows. The cover bodies are respectively installed on the first busbar trunking and the second busbar trunking, and both ends of the bellows are respectively connected to the cover bodies. The protective cover is used to seal the first connecting portion and the second connecting portion, prevent the first connecting portion and the second connecting portion from being exposed to the outside, prevent the first connecting portion and the second connecting portion from leaking electricity, and improve the safety of the first connecting portion and the second connecting portion.

[0009] Preferably, the first connecting portion is provided with a plurality of first slots arranged side by side. Both sides of the first slots are formed into first insertion portions. The second connecting portion is provided with second insertion portions corresponding to the first slots and second slots corresponding to the first insertion portions. When the first busbar trunking and the second busbar trunking are connected, the first insertion portions are inserted into the second slots, and the second insertion portions are inserted into the first slots, so as to form a rotatable insertion connection between the first connecting portion and the second connecting portion. By providing a plurality of first slots arranged side by side on the first connecting portion, forming first insertion portions on both sides, and providing corresponding second insertion portions and second slots on the second connecting portion, the contact area between the first connecting portion and the second connecting portion is increased, thereby improving the connection strength and reliability between the two.

[0010] Specifically, the rotation prevention holes are provided on the first insertion portions, and the radial dimension of the rotation prevention holes gradually increases from the middle first insertion portion to the first insertion portions on both sides. The rotation prevention block is provided with a rotation prevention portion adapted to the rotation prevention holes, and the rotation prevention portion is in fit connection with the rotation prevention holes. Since the radial dimension of the rotation prevention holes gradually increases from the middle to both sides, each second insertion portion can be exposed, so that when the rotation prevention block clamps the second connecting portion, the rotation prevention portions can all press against the second insertion portions, further improving the rotation prevention effect and reliability of the rotation prevention mechanism.

[0011] Specifically, the driving handle includes a transmission part that is drivingly connected to the anti-rotation block, and the transmission part is provided with positive and negative threads with opposite rotation directions, which are used to drive the anti-rotation part to press against or separate from the second plug part. The positive and negative threads provided on the transmission part realize the synchronous control of the pressing or separating state between the anti-rotation part and the second plug part. The user can simultaneously adjust the pressing force of the two anti-rotation blocks on the second connecting part through a single action of rotating the driving handle, thereby improving the convenience and efficiency of operation.

[0012] Preferably, the cover body comprises an upper cover and a lower cover that are detachably connected, the upper cover is provided with a first plug-in portion, the lower cover is provided with a second plug-in portion corresponding to the first plug-in portion, and when the upper cover and the lower cover are connected, the first plug-in portion is connected to the second plug-in portion. By designing the cover body as two parts of an upper cover and a lower cover that are detachably connected, and equipping the corresponding first plug-in portion and second plug-in portion, the entire assembly and disassembly process becomes extremely simple, and the user can realize the rapid assembly and disassembly of the cover body only through simple alignment and plug-in actions, thereby improving the convenience of assembly and disassembly of the cover body.

[0013] Specifically, the first plug-in portion is in the shape of a hook disposed horizontally, and the second plug-in portion is in the shape of a hole disposed horizontally, and when the upper cover and the lower cover are connected, the first plug-in portion is inserted horizontally into the second plug-in portion. The hook-shaped and hole-shaped connection mode of horizontal insertion can form a stable mechanical locking effect after insertion, and can resist external pulling or vibration to a certain extent, ensuring that the upper cover and the lower cover maintain a tight connection state after connection, and are not easy to loosen or fall off, further improving the reliability of the connection.

[0014] Specifically, the upper cover is also screwed with a top screw, one end of which is in contact with the first bus duct / second bus duct, so that the upper cover tightens the lower cover. The screwed top screw makes the installation process more flexible and convenient. The operator can adjust the screw-in depth of the top screw to accurately control the tightness between the upper cover and the lower cover, and the installation can be completed without complicated tools or cumbersome steps, thereby improving the convenience of installation.

[0015] Specifically, the end of the first plug-in portion is provided with an upwardly protruding anti-slip portion, and when the upper cover pulls the lower cover tightly, the top of the anti-slip portion is higher than the second plug-in portion. The anti-slip portion ensures that the first plug-in portion will not easily slip out of the second plug-in portion during the process of the upper cover pulling the lower cover tightly, thereby improving the stability and reliability of the connection between the upper cover and the lower cover.

[0016] Preferably, the inner walls of the first plug-in part and the second plug-in part are both provided with a flexible sealing layer, which can be closely attached to the contact surface of the first plug-in part and the second plug-in part to form a continuous, seamless barrier, thereby improving the sealing performance of the protective cover.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] As Figures 1-9 shown, an installation structure of a cast-in-place busbar trunking for outdoor high altitude includes a first busbar trunking 1 and a second busbar trunking 2. The first busbar trunking 1 is provided with a first connection part 11, and the second busbar trunking 2 is provided with a second connection part 12. The second connection part 12 is adapted to the first connection part 11, and the first connection part 11 is rotatably connected to the second connection part 12. By means of the rotational connection between the first connection part 11 and the second connection part 12, the angle between the first busbar trunking 1 and the second busbar trunking 2 is adjustable, and can be adjusted according to the specific terrain and building structure, improving the versatility of the busbar trunking.

[0033] In this embodiment, the first connection part 11 is provided with a plurality of first slots 111 arranged side by side, and both sides of the first slots 111 are formed as first insertion parts 112; the second connection part 12 is provided with second insertion parts 212 corresponding to the first slots 111 and second slots 211 corresponding to the first insertion parts 112. When the first busbar trunking 1 and the second busbar trunking 2 are connected, the first insertion parts 112 and the second slots 211 are inserted, and the second insertion parts 212 and the first slots 111 are inserted, so that a rotatable insertion connection is formed between the first connection part 11 and the second connection part 12. By arranging a plurality of first slots 111 arranged side by side in the first connection part 11, forming first insertion parts 112 on both sides, and arranging corresponding second insertion parts 212 and second slots 211 in the second connection part 12, the contact area between the first connection part 11 and the second connection part 12 is increased, thereby improving the connection strength and reliability between the two.

[0034] In this embodiment, the end faces of the first connecting portion 11 and the second connecting portion 12 are both arc-shaped. The arc-shaped end faces are used to remove the edges and corners of the first connecting portion 11 and the second connecting portion 12, preventing the edges and corners of the first connecting portion 11 and the second connecting portion 12 from damaging the bellows 32 when the first connecting portion 11 and the second connecting portion 12 rotate, and improving the service life of the bellows 32.

The rotation prevention block is provided with a rotation prevention portion adapted to the rotation prevention hole, and the rotation prevention portion is in fit connection with the rotation prevention hole. Since the radial dimension of the rotation prevention hole gradually increases from the middle to both sides, each second insertion portion 212 can be exposed. Thus, when the rotation prevention block clamps the second connecting portion 12, the rotation prevention portions can all press against the second insertion portions 212, further improving the rotation prevention effect and reliability of the rotation prevention mechanism 4.

[0037] Specifically, the driving handle 41 includes a transmission portion in transmission connection with the rotation prevention block. The transmission portion is provided with left- and right-handed threads with opposite helix directions for driving the rotation prevention portion to press against or separate from the second insertion portion 212. The provision of left- and right-handed threads on the transmission portion realizes the synchronous control of the pressing or separating state between the rotation prevention portion and the second insertion portion 212. The user can adjust the pressing force of the two rotation prevention blocks against the second connecting portion 12 simultaneously through a single action of rotating the driving handle 41, improving the convenience and efficiency of the operation.

[0038] It further includes a protective cover 3 covering the first connecting portion 11 and the second connecting portion 12. The protective cover 3 includes symmetrically arranged cover bodies 31 and a bellows cover 32. The cover bodies 31 are respectively installed on the first busbar trunking 1 and the second busbar trunking 2, and both ends of the bellows cover 32 are respectively connected to the cover bodies 31. The protective cover 3 is used to seal the first connecting portion 11 and the second connecting portion 12, prevent the first connecting portion 11 and the second connecting portion 12 from being exposed to the outside, prevent the first connecting portion 11 and the second connecting portion 12 from leaking electricity, and improve the safety of the first connecting portion 11 and the second connecting portion 12.

[0039] In this embodiment, the cover body 31 includes a detachable upper cover 311 and a lower cover 312. The upper cover 311 is provided with a first insertion portion 3111, and the lower cover 312 is provided with a second insertion portion 3121 corresponding to the first insertion portion 3111. When the upper cover 311 and the lower cover 312 are connected, the first insertion portion 3111 is connected to the second insertion portion 3121. By designing the cover body 31 into two parts, the detachable upper cover 311 and the lower cover 312, and equipping corresponding first insertion portion 3111 and second insertion portion 3121, the whole installation and disassembly process becomes extremely simple. The user can realize the rapid assembly and disassembly of the cover body 31 only through simple alignment and insertion actions, improving the convenience of installation and disassembly of the cover body 31.

[0040] Specifically, the first insertion portion 3111 is in the shape of a horizontally arranged hook, and the second insertion portion 3121 is in the shape of a horizontally arranged hole. When the upper cover 311 and the lower cover 312 are connected, the first insertion portion 3111 is horizontally inserted into the second insertion portion 3121. The horizontally inserted connection method of the hook and the hole can form a firm mechanical locking effect after insertion, can resist the pulling or vibration of external forces to a certain extent, ensure that the upper cover 311 and the lower cover 312 remain tightly combined after connection, are not easy to loosen or fall off, and further improve the reliability of the connection.

[0041] Specifically, a top screw rod is also screwed on the upper cover 311.

The screwed top screw rod makes the installation process more flexible and convenient. The operator can precisely control the tightening degree between the upper cover 311 and the lower cover 312 by adjusting the screwing depth of the top screw rod, and can complete the installation without complex tools or cumbersome steps, improving the installation convenience.

[0042] Specifically, an anti - detachment portion 3112 protruding upward is provided at the end of the first insertion portion 3111. When the upper cover 311 tightens the lower cover 312, the top of the anti - detachment portion 3112 is higher than the second insertion portion 3121. The anti - detachment portion 3112 ensures that the first insertion portion 3111 will not easily detach from the second insertion portion 3121 during the process of the upper cover 311 tightening the lower cover 312, improving the stability and reliability of the connection between the upper cover 311 and the lower cover 312.

[0043] In this embodiment, flexible sealing layers are provided on the inner walls of both the first insertion portion 3111 and the second insertion portion 3121. The flexible sealing layer can closely adhere to the contact surface between the first insertion portion 3111 and the second insertion portion 3121, forming a continuous and seamless barrier, improving the sealing performance of the protective cover 3.
