Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive crossarm technology, specifically a conductive crossarm for electric arc furnace immersion cooling. Background Technology
[0002] The electric arc furnace immersion cooling conductive cross arm is a device that improves conductivity through innovative cooling design. Its core feature is that the conductive copper busbar is directly immersed in cooling water, and natural circulation cooling is achieved by utilizing the water temperature difference.
[0003] The prior art patent document CN222352902U provides: a conductive crossarm for immersion cooling in an electric arc furnace, including a conductive crossarm body; an installation assembly disposed at one end of the conductive crossarm body; and a limiting assembly disposed on one side of the installation assembly. The installation assembly includes: a fixing ring, fixedly connected to the outer wall of the conductive crossarm body; a sliding hole block, fixedly connected to one side of the fixing ring; and a sliding groove plate disposed on the inner wall of the sliding hole block. By attaching the sliding hole block to the side of the object to be installed, and then sliding the fixing plate into the inner wall of the sliding hole block, the fixing ring is released when the sliding block reaches the appropriate position. The spring returns, causing the sliding block to lock into the groove of the sliding groove plate. By rotating the handle, the threaded rod rotates on the inner wall of the fixed threaded hole plate, causing the clamping plate to slide inward, so that the clamping plate and the fixing ring clamp the object. Similarly, the installation assembly can be disassembled, achieving the effect of quick installation and disassembly of the conductive crossarm body.
[0004] Although the device has many beneficial effects, it still has the following problems: its limiting and locking rely on spring elements. Under continuous vibration and high temperature environment, the spring is prone to fatigue, relaxation and thermal annealing, resulting in elastic failure, which makes the installation structure loose and poses a safety hazard. Secondly, the design does not integrate an efficient cooling system. The Joule heat generated by the cross arm body when energized cannot be dissipated in time, which can easily lead to overheating of the cross arm, increased resistance, increased power consumption, or even burnout, seriously affecting the life of the equipment and production efficiency.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0034] This utility model provides an overall structural schematic diagram of an embodiment of an electric arc furnace immersion cooling conductive crossarm, including:
[0035] Please see Figures 1-5This embodiment of an electric arc furnace immersion cooling conductive crossarm includes a crossarm body 100. A mounting assembly 200 is provided on the side wall of the crossarm body 100. The mounting assembly 200 includes a mounting bracket 210. A bidirectional lead screw 230 is inserted into the side wall of the mounting bracket 210. Multiple clamping plates 240 are threaded onto the outer circumference of the bidirectional lead screw 230. An optical shaft 233 is integrally formed and connected to the side wall of the bidirectional lead screw 230, providing a fulcrum for mounting and applying force to a cam handle 250. The cam handle 250 is hinged to the outer circumference of the optical shaft 233. A cooling assembly 300 is provided on the inner cavity side wall of the crossarm body 100. The cooling assembly 300 includes a partition 310. Multiple turbulence plates 330 are welded to the side wall of the partition 310 to disrupt the laminar flow of the coolant, making it turbulent. Heat sinks 340 are welded to the side wall of the partition 310.
[0036] It is worth noting that, in order to facilitate the connection of coolant to the outside of the crossarm body 100, specifically, the crossarm body 100 has a liquid inlet 120 and a liquid outlet 110 on its side wall for the entry and exit of coolant. At the same time, the liquid inlet 120 and the liquid outlet 110 are arranged on the same side to facilitate the connection of external pipelines and the overall layout.
[0037] Next, to facilitate the installation of the mounting component 200, specifically, a mounting plate 220 is welded to the inner wall of the mounting bracket 210 for connecting the mounting bracket 210 and the cross arm body 100. The cross arm body 100 is welded to the side wall of the mounting plate 220. A guide groove 211 is provided on the inner wall of the mounting bracket 210 to provide precise trajectory restriction for the sliding of the clamping plate 240.
[0038] Meanwhile, in order to improve the stability of the clamping plate 240, specifically, the side wall of the clamping plate 240 is integrally formed with a slider 241, the side wall of the slider 241 is slidably connected to the guide groove 211, the clamping plate 240 has a wedge structure, the wedge structure can generate a self-locking effect during the clamping process, the greater the vibration, the tighter the clamping, and the extremely high reliability.
[0039] Furthermore, to facilitate the driving of the bidirectional lead screw 230, a driving hole 231 is provided on the side wall of the bidirectional lead screw 230 for inserting a tool to rotate the bidirectional lead screw 230. The driving hole 231 has a hexagonal structure, which fits well with the tool, can withstand large torque, and is not prone to slippage or damage.
[0040] It is worth noting that, in order to facilitate the improvement of cooling effect in local areas, the heat sink 340 has multiple flow holes 341 on its side wall, which are used to guide the coolant to change its flow direction at the flow channel bend. The flow holes 341 have a conical structure, and the inner side wall of the flow holes 342 has a connecting hole 343. The side wall of the connecting hole 343 has a heat dissipation groove 342. The dense flow channel forces the coolant to flow meander in this area, prolonging the residence time and achieving localized key cooling.
[0041] Finally, to improve heat dissipation efficiency, specifically, the turbulence plate 330 has a square structure, and multiple turbulence plates 330 are staggered. The square structure and staggered distribution can maximize the disturbance of water flow. The turbulence can strongly scour the pipe wall, break the thermal boundary layer, and greatly improve the heat exchange efficiency. The baffle plate 320 has an arc-shaped structure. The arc-shaped structure conforms to fluid dynamics and can smoothly guide the water flow to change direction, reduce flow resistance, and reduce pump consumption.
[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0043] Combination Figures 1-5 The specific usage process of the electric arc furnace immersion cooling conductive cross arm according to this embodiment is as follows:
[0044] 1. Place the mounting bracket 210 of the crossarm body 100 onto the external support column for mounting the crossarm body 100. Insert the hex wrench into the drive hole 231 and rotate it to drive the double-acting screw 230 to rotate. This will cause the two wedge-shaped clamps 240 to move synchronously towards each other along the guide groove 211 until the column is firmly clamped. Move the cam handle 250 to press its eccentric part against the end face of the optical shaft 233. Use friction to lock the double-acting screw 230 to complete the installation.
[0045] 2: Connect the outlet pipe of the external cooling water source to the inlet 120 of the crossarm body through an external quick-connect coupling, and connect the return pipe of the external cooling water source to the outlet 110 of the crossarm body. Turn on the cooling system water pump, and the coolant flows in from the inlet 120. The coolant is deionized water. After absorbing heat, the coolant is discharged from the outlet 110 and flows to the external cooling tower through the return pipe connected to the outlet. The internal heat of the coolant is removed so that it can be circulated. After passing through the U-shaped flow channel and the complex flow channel inside the heat sink 340, it flows out from the outlet 110 to form a circulation and continuously cool the crossarm.
[0046] 3: Move the cam handle 250 to the release position to release the lock on the double-acting lead screw 230. Insert the hex wrench into the drive hole 231 and rotate it in the opposite direction to drive the two wedge clamps 240 to move synchronously in opposite directions, release the clamp on the column, remove the entire conductive cross arm from the column, and disconnect the coolant quick-change connector.
[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
