[0046] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0047] like Figure 1-4 As shown, an electric furnace change switch comprises:

[0048] Rack 100;

[0049] A first output block 210 and a second output block 220, the first output block 210 and the second output block 220 are mounted on the frame 100;

[0050] An input block 300 , the input block 300 is installed between the first output block 210 and the second output block 220 ;

[0051] A first connecting block 410, the first connecting block 410 is slidably disposed on the frame 100;

[0052] The first connection block 410 is adapted to contact and connect the input block 300 and the first output block 210;

[0053] A second connecting block 420, the second connecting block 420 is slidably disposed on the frame 100;

[0054] The second connection block 420 is adapted to contact and connect the input block 300 and the second output block 210;

[0055] A switching control device, the switching control device is connected to the first connection block 410 and the second connection block 420;

[0056] The switch control device is adapted to drive the first connection block 410 and the second connection block 420 to move in opposite directions to switch the connection between the input block 300 and the first output block or the connection between the input block 300 and the second output block 220 .

[0057] In this embodiment, if Figure 1 As shown, when the first connection block 410 contacts the input block 300 and the first output block 210, the second connection block 420 is driven by the switching control device to disconnect the connection between the input block 300 and the second output block 220; when the second connection block 420 contacts the input block 300 and the second output block 220, the first connection block 410 is driven by the switching control device to disconnect the connection between the input block 300 and the first output block 410, and the input block 300 is placed between the first output block 410 and the second output block 420, which facilitates the first connection block 410 to connect the input block 300 and the first output block 210 and the second connection block 420 to connect the input block 300 and the second output block 220. At the same time, the switching control device ensures the mutually exclusive relationship between the first output block 210 and the second output block 220 and the input block 300, and realizes the switching of the connection between the input block 300 and the first output block 210 and the second output block 220, thereby ensuring the reliability of the internal contact, avoiding the phenomenon of poor contact, and improving the stability of the operation of the electric furnace.

[0058] Specifically, Figure 1-3 As shown, the switching control device may have the following structure:

[0059] A drive assembly, the drive assembly is mounted on the frame 100;

[0060] A transmission screw 510, the transmission screw 510 is rotatably mounted on the frame 100;

[0061] The driving assembly is suitable for driving the transmission screw 510 to rotate;

[0062] A connection fulcrum is provided on the frame 100 between the first output block 210 and the second output block 220;

[0063] A lever 520, wherein the lever 520 is connected to a connection fulcrum of the frame 100;

[0064] One end of the lever 520 is slidably fitted on the transmission screw 510 through a nut;

[0065] A first connection block 410 and a second connection block 420 are respectively hinged on both sides of the lever 520 connected to the connection fulcrum;

[0066] One end of the lever is adapted to move horizontally under the drive of the transmission screw 510 and rotate around the connection fulcrum, thereby driving the first connection block 410 and the second connection block 420 to move relative to each other.

[0067] In this embodiment, if Figure 2 As shown, the switching control device uses the lever 520 to achieve output switching through the driving component. At the same time, the screw transmission of the transmission screw 510 and the nut can provide a large and stable force transmission to ensure the force required for pushing and switching the lever 520.

[0068] Specifically, Figure 1-3 As shown, a limit switch 110 is also provided on the frame 100 , and the limit switch 110 is suitable for limiting the horizontal movement range of the lever 520 on the transmission screw 510 .

[0069] In this embodiment, if Figure 1-4 As shown, there are two limit switches 110, which are arranged at the positions after the first connection block 410 and the second connection block 420 are connected in place.

[0070] Specifically, Figure 1-3 As shown, the drive component can be structured as follows:

[0071] Motor 501, motor 501 is mounted on the frame 100;

[0072] A reducer 502, wherein the input end of the reducer 502 is connected to the output end of the motor 501;

[0073] The output end of the speed reducer 502 is connected to the transmission screw 510;

[0074] The motor 501 is adapted to drive the transmission screw 510 to rotate via the reducer 502 .

[0075] In this embodiment, if Figure 1-3 As shown, the function of the driving component is to provide driving force, drive the transmission screw 510 to rotate, and then drive the lever 520 to work. The motor 501 is installed on the frame 100, and its output end is connected to the transmission screw 510 after being reduced in speed by the reducer 502. The reducer 502 plays the role of amplifying the driving torque, so that the motor 501 can provide a sufficiently large torque to drive the transmission screw 510 to rotate.

[0076] Specifically, Figure 1 As shown, the conductive parts of the input block 300, the first output block 210 and the second output block 220 are water-cooled copper bars;

[0077] There are water cooling interfaces on the water cooling copper bars.

[0078] In this embodiment, if Figure 1As shown, the water-cooled copper bar has a hollow structure inside, which is convenient for the coolant to flow through to take away the heat, thereby playing a cooling role. In practical applications, the input block 300, the first output block 210 and the second output block 220 will generate heat when they are powered on and carry current. If this part of the heat cannot be taken away in time, their service life will be reduced. The water-cooling interface can be connected to an external water-cooling pipeline. When the coolant in the water-cooling pipeline flows through the water-cooled copper bar, it can take away the generated heat, so that the normal working temperature of the input block 300, the first output block 210 and the second output block 220 can be guaranteed to avoid the occurrence of overheating.

[0079] Specifically, Figure 1-4 As shown, the electric furnace change switch further includes a water distributor 610, which is installed in the frame 100;

[0080] The water distributor 610 is provided with eight water nozzles 620;

[0081] The water nozzles 620 are respectively connected to the water cooling interfaces of the corresponding water cooling copper bars.

[0082] In this embodiment, if Figure 1 and Figure 4 As shown, in order to better manage and distribute the coolant to each water-cooled copper bar, the utility model further provides a water distributor 610, and the water nozzles 620 are respectively connected to the water-cooled copper bars of the input block 300, the first output block 210, and the second output block 220, that is, each water nozzle 620 is respectively connected to the water-cooled interface of the corresponding water-cooled copper bar. When the coolant enters the water distributor 610 from the external pipeline, the water distributor 610 can distribute and guide the coolant to each water-cooled copper bar in an orderly manner. The water distributor 610 plays the role of conducting and distributing the coolant here, and reasonably configures and adjusts the flow rate of the coolant. The setting of eight water nozzles 620 allows the coolant to be smoothly and accurately introduced into each water-cooled copper bar to avoid leakage. At the same time, the eight water nozzles 620 also facilitate the disassembly and installation of the water pipe. In some embodiments, the number of water nozzles 620 is not limited to eight, and can be set according to specific needs. The water nozzle 620 can be made of stainless steel.

[0083] Specifically, Figure 1 As shown, the water separator 610 is also provided with a temperature control sensor, which is suitable for detecting the temperature of the coolant flowing through the water separator 610 .

[0084] In this embodiment, in order to monitor the cooling working condition in real time, the setting of the temperature control sensor can play a dual role: first, it can monitor the temperature change of the coolant itself. When the coolant temperature is too high, it means that its cooling effect has begun to decrease. At this time, it may be necessary to add coolant or increase flow rate and other measures to ensure the cooling effect; second, it can indirectly monitor the heat load of the water-cooled copper busbar, because the heat generated by the water-cooled copper busbar will first be transferred to the coolant. When the heat load is greater, the coolant takes away more heat, so the temperature of the coolant will also increase accordingly. Therefore, by detecting the changing trend of the coolant temperature, the heat load of the water-cooled copper busbar can be reflected. Therefore, setting a temperature control sensor allows the operator to grasp the cooling working status at any time, so as to optimize and adjust in time to ensure long-term stable and reliable operation.

[0085] Specifically, Figure 1-3 As shown, the rack 100 is further provided with a control connection terminal 700, and the control connection terminal 700 is respectively connected to the switching control device and the temperature control sensor.

[0086] In this embodiment, if Figure 1 and Figure 3 As shown, the electric furnace switch also includes an external controller. In order to facilitate the control and monitoring of the external controller, the external controller can monitor the temperature feedback data of the temperature control sensor in real time through the control connection terminal 700, and dynamically adjust the flow rate, temperature and other parameters of the coolant according to the temperature data. At the same time, the external controller can also send a control instruction to the switching control device through the control connection terminal 700 to drive the transmission screw 510 to rotate, and promote the first connection block 410 and the second connection block 420 to switch the movement, so as to realize the switching control between the input block 300 and the first output block 210 or the second output block 220. Therefore, the control connection terminal 700 is set, which can not only adjust the cooling according to the feedback of the temperature control sensor, but also switch different working modes, so that it can flexibly adapt to different working environments and control requirements, thereby realizing a more optimized and efficient working mode. The control connection terminal 700 can specifically have a 12-core temperature control line plug, a 10-core signal line plug and a 4-core power line plug.

[0087] Specifically, Figure 1-3 As shown, the rack 100 is further provided with six connecting copper bars 800 extending outside the rack 100 , and the connecting copper bars 800 are connected to the corresponding input blocks 300 , the first output blocks 210 and the second output blocks 220 .

[0088] In this embodiment, if Figure 1-3As shown, in order to facilitate the connection with the external circuit, the water-cooled copper bars on the input block 300, the first output block 210 and the second output block 220 can be stably and reliably connected to the external circuit by setting the connecting copper bar 800. The connecting copper bar 800 extends out of the rack 100, so that the operator can easily tighten the connection to achieve electrical connection with the external circuit. At the same time, the connecting copper bar 800 itself also has good electrical and thermal conductivity. The heat generated by the input block 300, the first output block 210 and the second output block 220 during the working process can be quickly discharged through the connecting copper bar 800 to avoid heat accumulation. In addition, the cross-sectional area of ​​the connecting copper bar 800 is large, so that the connection resistance can be reduced to a certain extent, which is conducive to the circulation of large currents and improves the current carrying capacity. Therefore, the connecting copper bar 800 extending outside the rack 100 is set to further improve the connection capability and play a role in auxiliary heat dissipation, thereby improving its performance.

[0089] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
