[0022] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application 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 only used to explain the present application and are not used to limit the present application.

[0023] The present application provides a display device applied to a rectifier substation to solve the problem that during the production process of electrolytic aluminum, a rectifier substation is usually required to supply power to the electrolytic cells in the electrolysis workshop. In the related art, since the working voltage of the electrolytic cells during operation is usually only displayed on a small screen on the stability control cabinet, it is inconvenient for the staff to monitor the working voltage of the electrolytic cells.

[0024] Specifically, as Figure 1 and Figure 2 shown, the display device includes a cover body and a display screen; wherein, the cover body has an electromagnetic shielding function, and the cover body can be made of a material with an electromagnetic shielding function. The cover body has a receiving cavity. An opening penetrating the cover body is provided on the outer side surface of the cover body, and a transparent seal is installed in the opening. The periphery of the transparent seal is hermetically connected to the inner wall surface of the opening; the display screen is used for electrically connecting with the voltage monitor in the rectifier substation, and the display screen is used for displaying the working voltage of the electrolytic cell. The display surface of the display screen faces the transparent seal. The display screen can be an LCD display screen or an OLED display screen or other types of display screens. The present application does not make specific limitations on the specific type and size of the display screen.

[0025] It can be understood that the voltage monitor in the rectifier substation can monitor the working voltage provided by the rectifier substation for the electrolytic cells in the electrolysis workshop, and the display screen can display the working voltage monitored by the voltage monitor. During the production process of electrolytic aluminum, the staff can also directly see the real-time working voltage of the electrolytic cells from the display screen, so that the staff can more conveniently monitor the working voltage of the electrolytic cells, which is beneficial for the staff to judge whether the working voltage is abnormal and can make timely responses when the working voltage of the electrolytic cells is abnormal, increasing the safety factor during the operation of the equipment.

[0026] In addition, as is known to those skilled in the art, there are many electronic devices in the rectifier station, which will generate a large amount of electromagnetic signals during operation. These signals may interfere with the normal display of the display screen and may even cause damage to the display screen. In this application, the cover has an electromagnetic shielding function, which can provide electromagnetic protection for the display screen inside the cover, weaken the interference of electromagnetic signals on the display screen, and thus ensure the normal display of the display screen. At the same time, the staff can normally observe the picture displayed on the display screen through the transparent seal, so that the staff can conveniently monitor the working voltage of the electrolytic cell in real time.

[0027] In some embodiments of the present application, the transparent seal is an electromagnetic shielding glass. The electromagnetic shielding glass has a good light transmittance, so that the light emitted by the display screen can pass through the electromagnetic shielding glass smoothly, so that the staff can normally observe the picture displayed on the display screen through the transparent seal. In addition, the electromagnetic shielding glass has an electromagnetic shielding function, which can prevent the electromagnetic signals outside the cover from entering the cover through the electromagnetic shielding glass, thereby further weakening the interference of the electromagnetic signals outside the cover on the display screen.

[0028] In some embodiments of the present application, the cover is a metal shielding cover. On the basis of having an electromagnetic shielding function, the metal shielding cover generally also has good structural strength and can provide good protection for the display screen. Among them, the preparation material of the cover can be copper, aluminum, aluminum alloy, copper alloy, steel or other materials with electromagnetic shielding functions.

[0029] Continue to refer to Figure 2 As shown, in some embodiments of the present application, heat dissipation fins are arranged on the outer side surface of the cover, and the heat dissipation fins are in contact with the cover. The heat generated when the display screen works can be dissipated through the cover and the heat dissipation fins. The heat dissipation fins can improve the heat dissipation performance and heat dissipation efficiency of the display device, thereby preventing the display screen from being damaged due to excessive temperature. Among them, the heat dissipation fins can be integrally formed with the cover, or the heat dissipation fins can be connected to the cover by welding, gluing, threaded connection or riveting; the preparation material of the heat dissipation fins can be copper, aluminum, aluminum alloy, copper alloy or other materials with good heat dissipation performance.

[0030] As Figure 3As shown, in some embodiments of the present application, a wire routing hole is provided on a side of the cover opposite to the opening. The display screen is electrically connected to the voltage monitor through a connecting wire passing through the wire routing hole. The connecting wire can be a power line, a data line, or other conductive wires. The wire routing hole can provide a routing channel for the connecting wire, so that the display screen can be smoothly electrically connected to the voltage monitor through the connecting wire. In addition, the electrical connection jack on the display screen is usually located on a side of the display screen opposite to the display surface. By providing the wire routing hole on a side of the cover opposite to the opening, the wire routing hole can be on the same side as the electrical connection jack on the display screen, making it more convenient to connect the connecting wire to the electrical connection jack.

[0031] Furthermore, a sealing ring is provided in the wire routing hole. The peripheral side of the sealing ring is sealingly connected to the hole wall of the wire routing hole. The connecting wire passes through the sealing ring. The sealing ring can ensure the sealing between the connecting wire and the hole wall of the wire routing hole, preventing dirt, moisture, etc. from entering the accommodation cavity through the gap between the connecting wire and the hole wall of the wire routing hole.

[0032] Even further, the sealing ring is a metal sealing ring. The metal sealing ring has good sealing performance and also has a certain electromagnetic shielding function. It can prevent electromagnetic signals from entering the accommodation cavity through the gap between the connecting wire and the hole wall of the wire routing hole, and can improve the electromagnetic shielding performance of the cover.

[0033] As Figure 4 shown, in some embodiments of the present application, the display device further includes a mounting assembly. The mounting assembly is connected to the cover and is used to connect to the wall of the rectifier station to mount the cover on the wall of the rectifier station. It can be understood that the cover can be mounted on the wall of the rectifier station through the mounting assembly, making it more convenient for the staff to view the display screen at any time.

[0034] Specifically, the mounting assembly includes a slide rail, a mounting frame, and a driving member. The slide rail extends vertically and is used to be fixed on the wall of the rectifier station. The mounting frame is fixedly connected to the cover and is slidably connected to the slide rail vertically. The driving member is connected to the mounting frame and is used to drive the mounting frame to slide vertically.

[0035] It can be understood that when mounting the cover on the wall, first fix the slide rail on the wall, then connect the mounting frame to the slide rail and fix the mounting frame to the back side of the cover, and the mounting of the cover on the wall can be achieved. In addition, by driving the cover to slide vertically through the driving member, the height of the cover can be adjusted, making it more convenient for the staff to view the display screen at any time.

[0036] Furthermore, the driving member includes a screw rod. A limiting block is fixed to the side of the sliding rail. The screw rod extends vertically through the mounting frame and the limiting block. The screw rod is threadedly connected to the mounting frame and rotatably connected to the limiting block. A hand crank is fixed to the top of the screw rod. It can be understood that when a staff member holds the hand crank and rotates it, the screw rod can be driven to rotate. The screw rod drives the mounting frame to slide vertically through the threaded connection with the mounting frame, thereby driving the cover body to move vertically, and the height of the cover body can be adjusted.

[0037] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
