As used in this description, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise.

[0028] Please refer to Figures 1 to 5 The application embodiment provides an electrolytic tank safety alarm device, which comprises an electrolytic tank body, a first anode guide rod 21, a second anode guide rod 22, a first horizontal bus 31, a second horizontal bus 32, a busbar 40 and two alarm devices 50. The electrolytic tank of the application embodiment can be a 600KA electrolytic tank and is mainly used for aluminum electrolysis.

[0029] The electrolytic tank body is internally provided with electrolyte. The first anode guide rod 21 and the second anode guide rod 22 are arranged at intervals and partially contact the electrolyte. In some embodiments, the first anode guide rod 21 and the second anode guide rod 22 are anode carbon blocks. The first horizontal bus 31 and the second horizontal bus 32 are located between the first anode guide rod 21 and the second anode guide rod 22, and the first horizontal bus 31 is connected to the first anode guide rod 21 and the second horizontal bus 32 is connected to the second anode guide rod 22; the busbar 40 is connected to the first horizontal bus 31 and the second horizontal bus 32 and is located between the first horizontal bus 31 and the second horizontal bus 32.

[0030] It should be noted that in the process of electrolysis, the anode carbon blocks are continuously consumed, and the first horizontal bus 31 connected to the first anode guide rod 21 and the second horizontal bus 32 connected to the second anode guide rod 22 will both be lowered. If the first horizontal bus 31 and the second horizontal bus 32 are not on the same horizontal line, misalignment will occur, which can easily lead to uneven distribution of current in the electrolytic tank, unstable quality of electrolytic products and other situations.

[0031] Based on this, the application embodiment designs an alarm device 50, please refer to Figures 2 to 4The alarm device 50 comprises alarm components 510, driving rods 520 and alarmers 530. One alarm component 510 is installed on the first horizontal busbar 31, and the other alarm component 510 is installed on the second horizontal busbar 32. The bottom end of the driving rod 520 is connected to the busbar 40. The alarm component 510 comprises a shell 511, limit switches 512, connecting rods 513 and driving plates 514. The shell 511 has an open-ended accommodation cavity. The limit switches 512 are installed on the cavity bottom wall of the accommodation cavity and electrically connected with the alarmers 530. The driving rods 520 are installed in the accommodation cavity. One end of the driving plate 514 is sleeved on the connecting rod 513, and the other end thereof can swing around the connecting rod 513. The other end of the driving plate 514 is fixed with the top end of the driving rod 520. The alarmers 530 are installed on the outer side of the shell 511. One shell 511 of the alarm component 510 is installed on the inner side of the first horizontal busbar 31, and the other shell 511 of the alarm component 510 is installed on the inner side of the second horizontal busbar 32.

[0032] Specifically, when the first horizontal busbar 31 and the second horizontal busbar 32 are in the process of descending, one of which descends too fast, so that the first horizontal busbar 31 and the second horizontal busbar 32 are not in the same horizontal line. In this case, the busbar 40 between the first horizontal busbar 31 and the second horizontal busbar 32 is deformed under stress. It can be understood that when the first horizontal busbar 31 is lower than the second horizontal busbar 32, the busbar 40 close to the first horizontal busbar 31 side will be lower than the busbar 40 close to the second horizontal busbar 32 side, so that the busbar 40 will be partially higher than the horizontal busbar located at the low point. Thus, the busbar 40 will drive the driving rod 520 to move, so that the driving plate 514 swings around the connecting rod 513 and triggers the limit switch 512. The buzzer alarm 530 will issue an alarm after receiving the signal. The embodiment of the present application can quickly alarm the user when the first horizontal busbar 31 and the second horizontal busbar 32 are misaligned, which helps to prevent problems during the operation of the electrolytic cell.

[0033] In order to facilitate the control of the alarm work of the alarmers 530, the alarm device 50 of the present application further comprises a controller 540 installed on the outer side of the shell 511. The controller 540 is electrically connected with the limit switches 512 and the alarmers 530. When the limit switch 512 is touched by the driving plate 514, it will send a signal to the controller 540, and then the controller 540 controls the alarmers 530 to issue an alarm voice.

[0034] In order to improve the stability of the driving rod 520 installed on the busbar 40, please refer to Figure 5The alarm device 50 further comprises a mounting block 570 mounted on the busbar 40 and provided with a mounting hole 571 in which the bottom end of the driving rod 520 is inserted. The mounting block 570 can provide additional support and fixation, making the driving rod 520 more firmly mounted on the busbar 40 and helping to reduce the shaking and instability of the driving rod 520 during movement. The mounting block 570 can provide a stable support platform, making the installation of the driving rod 520 simpler and faster. The operator only needs to insert the bottom end of the driving rod 520 into the mounting hole 571 to complete the installation, without the need for additional fixing and adjusting steps.

[0035] In some embodiments of the present application, the distance between the driving plate 514 and the limit switch 512 is not less than 5 mm and not more than 15 mm, so that the driving rod 520 is driven to drive the driving plate 514 to touch the limit switch 512 only when the busbar 40 is deformed enough.

[0036] Further, the alarm device 50 of the embodiments of the present application further comprises a spring 560 mounted in the accommodating cavity and abutting against the cavity bottom wall and the driving plate 514 on opposite sides. The present application sets the spring 560 between the cavity bottom wall and the driving plate 514, i.e. adds the spring 560 between the limit switch 512 and the driving plate 514. In this way, the spring 560 applies an outward force to the driving plate 514, preventing the driving plate 514 from accidentally touching the limit switch 512. In this way, only when the busbar 40 is deformed to a certain extent can the driving rod 520 drive the driving plate 514 to trigger the limit switch 512.

[0037] Further, the embodiments of the present application further comprise a protective cover 550 connected with the housing 511 and covering the outside of the controller 540 and the alarm 530. In this way, the protective cover 550 can effectively protect the controller 540 and the alarm 530 from being collided, pressed or damaged by external objects. The outer surface of the protective cover 550 is provided with a plurality of through holes 551 penetrating into the interior. The through holes 551 can reduce the resistance and reflection of sound, allowing the alarm 530 to emit sound more quickly and improving the response speed of the alarm. In this way, the protective cover 550 not only protects the controller 540 and the alarm 530, but also allows the sound of the alarm 530 to spread in multiple directions, improving the coverage of the sound and ensuring that the alarm information is conveyed more widely.

[0038] In some connection modes, the outer side of the shell 511 is provided with a clamping groove 511a, the protective cover 550 is provided with a buckle 552, and the buckle 552 is clamped with the clamping groove 511a to fixedly connect the shell 511 and the protective cover 550. The connection mode of the buckle 552 and the clamping groove 511a is relatively simple, easy to operate and install. Users can easily install the protective cover 550 on the shell 511 without the need for complex tools.
