[0002] In the production of electrolytic aluminum, the rectified direct current is introduced into the electrolytic cell through the aluminum busbar. The cells are connected in series by the column busbar. The busbar short circuit between the column busbars is a key protective part in the aluminum electrolytic production process and is the first source of danger in the aluminum smelting process.

[0003] In related technologies, busbar short circuits are usually separated by only a single protective plate, and the busbar short circuits are not effectively protected. Utility Model Content

[0004] This application provides a busbar short-circuit protection device, which enables effective protection against busbar short circuits.

[0005] Specifically, a busbar short-circuit protection device includes: a enclosure structure, which is arranged around and fitted to the busbar short-circuit, the enclosure structure including multiple side plates arranged along the periphery of the busbar short-circuit, each side plate corresponding to a side surface of the busbar short-circuit, and adjacent side plates being detachably connected by a high-temperature resistant and insulating first connector, the side plates being high-temperature resistant and insulating side plates; a top barrier structure, which is disposed on the top of the enclosure structure and surrounds the periphery of the busbar short-circuit, the top barrier structure being detachably connected to the enclosure structure by a high-temperature resistant and insulating second connector; wherein, a handle is provided on the outer surface of each side plate, the handle being detachably connected to the side plate by a high-temperature resistant and insulating third connector.

[0006] In some embodiments, one of the two adjacent side plates is a first side plate and the other is a second side plate. A slot is provided on the end face of the first side plate adjacent to the second side plate. The slot passes through the inner and outer sides of the first side plate. A block is provided on the end face of the second side plate adjacent to the first side plate. The block engages with the slot.

[0007] In some embodiments, the card block is integrally formed with the second side plate.

[0008] In some embodiments, multiple card slots are provided, and the multiple card slots are arranged at vertical intervals, with each card block corresponding to one of the card slots.

[0009] In some embodiments, the end face of the first side plate adjacent to the second side plate is flush with the outer surface of the second side plate.

[0010] In some embodiments, the first connector is a carbon bolt, which passes through the outer side of the first side plate and is inserted into the second side plate. The first connector is threadedly connected to both the first and second side plates.

[0011] In some embodiments, the top retaining structure includes multiple top plates arranged around the periphery of the busbar short circuit, the top plates being generally L-shaped; wherein, the top plate includes a first connecting portion and a second connecting portion perpendicular to the first connecting portion, the first connecting portion being located above the first side plate and detachably connected to the first side plate, and the second connecting portion being located above the second side plate and detachably connected to the second side plate.

[0012] In some embodiments, each of the top plates is provided with at least two second connectors, the second connectors being arranged vertically, at least one second connector passing through the first connecting portion and inserted into the first side plate, and at least one second connector passing through the second connecting portion and inserted into the second side plate.

[0015] The beneficial effects of this application are as follows: By using a fencing structure to protect the perimeter of the busbar short-circuit point and a top fencing structure to protect the exposed portion of the top of the busbar short-circuit point, comprehensive protection can be provided, effectively protecting the busbar short-circuit point. When abnormal situations such as aluminum molten metal splashing occur in the aluminum electrolysis cell, the protective device can effectively block the splashed aluminum molten metal. Furthermore, during electrode switching, when removing the hot residual electrode, the protective device also provides good heat insulation, preventing the busbar short-circuit point from being damaged by high temperatures, thus effectively improving the safety of the busbar short-circuit point. In addition, by installing a detachable handle, the handle can be removed after the protective device is installed, preventing it from being damaged by high temperatures and preventing it from becoming too hot for workers to grip. When it is necessary to disassemble the side plate, the handle can be reinstalled on the side plate via a third connector.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] This application provides a busbar short-circuit protection device, such as... Figure 1 and Figure 2 As shown, the busbar short-circuit point 50 protection device includes a enclosure structure 10 and a top retaining structure 20. The enclosure structure 10 surrounds the busbar short-circuit point 50 (e.g., Figure 3The enclosure structure 10 includes multiple side plates arranged along the periphery of the busbar short-circuit 50. Each side plate corresponds one-to-one with a side surface of the busbar short-circuit 50. Adjacent side plates are detachably connected by a high-temperature resistant and insulating first connector 31. The side plates are high-temperature resistant and insulating. The top enclosure structure 20 is located on top of the enclosure structure 10 and surrounds the periphery of the busbar short-circuit 50. The top enclosure structure 20 is detachably connected to the enclosure structure 10 by a high-temperature resistant and insulating second connector 32. The busbar short-circuit 50 can be elongated and has four side surfaces. There are four side plates, and each of the four side plates corresponds one-to-one with one of the four side surfaces of the busbar short-circuit 50. That is, one side plate corresponds to one side surface of the busbar short-circuit 50.

[0025] Understandably, by using the enclosure structure 10 to protect the perimeter of the busbar short circuit 50 and the top enclosure structure 20 to protect the exposed portion of the busbar short circuit 50, the busbar short circuit 50 can be protected in all aspects, thus effectively protecting the busbar short circuit 50. When abnormal situations such as aluminum liquid splashing occur in the aluminum electrolysis cell, the protective device can effectively block the splashed aluminum liquid. Furthermore, when removing the hot residual electrode during electrode switching, the protective device can also play a good heat insulation role, preventing the busbar short circuit 50 from being baked by high temperature, which can effectively improve the safety of the busbar short circuit 50.

[0026] It should also be noted that the side panels, the first connector 31 connecting adjacent side panels, and the second connector 32 connecting the top retaining structure 20 and the enclosure structure 10 are all made of high-temperature resistant insulating material. This prevents the first connector 31 and the second connector 32 from being damaged by high temperatures, which would make it impossible to assemble and disassemble the top retaining structure 20 and the enclosure structure 10, thus making the assembly and disassembly of the top retaining structure 20 and the enclosure structure 10 more convenient and reliable. The side panels can be made of insulating carbon board, insulating asbestos board, insulating glass board, or other high-temperature resistant insulating materials.

[0027] Specifically, a handle 40 is provided on the outer surface of the side panel, and the handle 40 is detachably connected to the side panel via a high-temperature resistant and insulating third connector 33. It is understood that when the side panel needs to be removed after use, the temperature on the side panel is generally high, and the side panel is generally large in size and weight, making it difficult for workers to find a good point of leverage when removing it. In this embodiment, by installing a detachable handle 40, the handle 40 can be removed after the protective device is installed, preventing the handle 40 from being damaged by high temperatures and also preventing the handle 40 from becoming too hot to grip. When the side panel needs to be removed, the handle 40 can be reinstalled on the side panel via the third connector 33. At this time, although the side panel is hot, the temperature of the handle 40 remains relatively low, allowing workers to grip the handle 40 to remove the side panel, making the removal of the side panel more convenient.

[0028] The handle 40 is a heat-insulated handle 40, which can prevent the heat from the side plate from being rapidly transferred to the handle 40 in a short time, thus preventing the handle 40 from overheating. The handle 40 can be made of materials with poor thermal conductivity and high strength, such as foamed ceramic, foamed glass, and alumina ceramic.

[0029] In one embodiment, a corrugated structure may be provided on the inner surface of the side plate to improve the roughness of the inner surface of the side plate and prevent the side plate from being too tightly attached to the busbar short circuit, which would make the side plate difficult to disassemble.

[0030] See Figures 1 to 3 As shown, one of the two adjacent side plates is a first side plate 11 and the other is a second side plate 12. A slot 111 is provided on the end face of the first side plate 11 and the second side plate 12 adjacent to each other. The slot 111 penetrates the inner and outer sides of the first side plate 11. A block 121 is provided on the end face of the second side plate 12 adjacent to the first side plate 11. The block 121 engages with the slot 111. It is understood that the first side plate 11 and the second side plate 12 are any two adjacent side plates in the enclosure structure 10. When assembling the enclosure structure 10, any two adjacent side plates can be spliced ​​by the cooperation of the locking block 121 and the locking slot 111. First, adjust the position of the first side plate 11 and make it fit with the busbar short circuit 50. Then, adjust the position of the second side plate 12 so that the locking block 121 and the slot of the locking slot 111 are opposite each other. Move along the thickness direction of the second side plate 12 towards the busbar short circuit 50 so that the locking block 121 is inserted into the slot 111 through the slot of the locking slot 111, thereby realizing the assembly of the first side plate 11 and the second side plate 12, making the assembly of the first side plate 11 and the second side plate 12 more convenient.

[0031] Furthermore, the locking block 121 is integrally formed with the second side plate 12, which can improve the connection strength between the locking block 121 and the second side plate 12. Furthermore, multiple locking slots 111 are provided, and the multiple locking slots 111 are arranged at vertical intervals. The locking block 121 corresponds to each locking slot 111, which can improve the splicing strength between the first side plate 11 and the second side plate 12 and prevent the first side plate 11 and the second side plate 12 from separating during use.

[0032] See also Figure 3 As shown, in one embodiment, the end face of the first side plate 11 adjacent to the second side plate 12 is flush with the outer surface of the second side plate 12, so that the enclosure structure 10 of the protective device is more compact and the overall volume of the protective device is reduced.

[0033] In one embodiment, the first connector 31 is a carbon carbon bolt. The first connector 31 passes through the outer side of the first side plate 11 and is inserted into the second side plate 12. The first connector 31 is threadedly connected to both the first side plate 11 and the second side plate 12. It is understood that a carbon carbon bolt is a composite material composed of carbon fiber and a resin matrix, possessing excellent strength, high-temperature resistance, and insulation properties. This enhances the connection strength between the first side plate 11 and the second side plate 12 while preventing the first connector 31 from being damaged by high temperatures.

[0034] In one embodiment, the third connector 33 may also be a carbon bolt. The third connector 33 passes through the mounting portion of the handle 40 and is inserted into the side plate. The third connector 33 is threadedly connected to the side plate, making it easier to install and remove the handle 40.

[0035] like Figures 1 to 4 As shown, in one embodiment, the top retaining structure 20 includes multiple top plates 21 arranged along the periphery of the busbar short circuit 50. The top plates 21 are generally L-shaped. It can be understood that the top retaining structure 20 is spliced ​​together from multiple L-shaped top plates 21. When the busbar short circuit 50 is elongated, the number of top plates 21 is 4, and the 4 top plates 21 are respectively set to correspond one-to-one with the 4 corners of the busbar short circuit 50, that is, 1 top plate 21 is set to correspond to 1 corner of the busbar short circuit 50.

[0036] The top plate 21 includes a first connecting portion 211 and a second connecting portion 212 perpendicular to the first connecting portion 211. The first connecting portion 211 is located above the first side plate 11 and is detachably connected to the first side plate 11. The second connecting portion 212 is located above the second side plate 12 and is detachably connected to the second side plate 12. It is understood that the top plate 21 can provide protection for the exposed portion of the busbar short-circuit outlet 50, and at the same time, the top plate 21 can also strengthen the connection between the first side plate 11 and the second side plate 12, preventing the first side plate 11 and the second side plate 12 from separating during use. Furthermore, the first connecting portion 211 can be integrally formed with the second connecting portion 212.

[0037] In one embodiment, each of the top plates 21 is provided with at least two second connectors 32, the second connectors 32 being arranged vertically, at least one second connector 32 passing through the first connecting portion 211 and inserted into the first side plate 11, and at least one second connector 32 passing through the second connecting portion 212 and inserted into the second side plate 12.

[0038] It is understood that each top is provided with at least two through holes for the second connector 32 to be inserted. The first side plate 11 and the second side plate 12 are both provided with insertion holes for the second connector 32 to be inserted. The insertion holes are positioned opposite each other as through holes. When installing the protective device, after assembling the side plates and connecting and fixing them with the first connector 31, the top plate 21 is placed on top of the side plates. After adjusting the position of the top plate 21 so that the insertion holes are aligned with the through holes, the second connector 32 is inserted vertically into the through holes and insertion holes, thereby fixing the top plate 21. At the same time, the connection between the first side plate 11 and the second side plate 12 can be strengthened through the top plate 21.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
