Description

Technical Field

[0001] The utility model relates to the technical field of conductive devices, in particular to a bypass device. Background Art

[0002] In an industrial environment of continuous production, such as in aluminum electrolysis, water treatment or other industrial processes that require the use of electrolytic cells, the reliability and continuous operation of electrolytic cells are crucial. However, in actual operation, due to various reasons (such as material fatigue, corrosion or mechanical failures), one or several electrolytic cells may malfunction and need to be maintained or replaced. In a traditional series electrolytic cell system, when one or several electrolytic cells fail, it is usually necessary to cut off the power supply of the entire electrolytic cell system in order to repair or replace the faulty cell, which not only affects production efficiency but also increases downtime and maintenance costs. Now, the utility model designs a bypass device to solve the above technical problems. Summary of the Utility Model

[0003] The utility model provides a bypass device, aiming to solve the problem that when one or several electrolytic cells fail, it is necessary to cut off the power supply of the entire electrolytic cell system, thereby increasing downtime and maintenance costs. On the other hand, through the adaptive ability of the flexible copper strip, the power connection part of the power connection assembly can be conveniently and well combined with the power connection head of the electrolytic cell. The technical solution is as follows:

[0004] A bypass device: comprising a vehicle body, a first conductive plate, a second conductive plate, a switch, and a power connection assembly. Universal wheels are installed at the bottom of the vehicle body, and the switch is installed on the vehicle body. The switch connects or disconnects the electrical connection between the first conductive plate and the second conductive plate. Both the first conductive plate and the second conductive plate are connected to the power connection assembly; the power connection assembly is used to connect to the power connection head of the electrolytic cell.

[0005] Based on the above technical solution, both the first conductive plate and the second conductive plate include an upper plate and a lower plate. The power connection assembly includes a clamping part, a flexible connection part, and a power connection part. The clamping part is fixed between the upper plate and the lower plate through fastening bolts.

[0017] The following further illustrates the present utility model in conjunction with the drawings and examples:

[0018] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] As Figure 1 shown, a job-hopping device includes a vehicle body 1, a first conductive plate 2, a second conductive plate 3, a make-break switch 4, and a power connection assembly 5. A universal wheel 11 is installed at the bottom of the vehicle body 1, and the make-break switch 4 is installed on the vehicle body 1. The make-break switch 4 connects or disconnects the electrical connection between the first conductive plate 2 and the second conductive plate 3. Both the first conductive plate 2 and the second conductive plate 3 are connected to the power connection assembly 5; the power connection assembly 5 is used to connect to the power connection head 611 of the electrolytic cell.

[0022] As Figure 2 shown, both the first conductive plate 2 and the second conductive plate 3 include an upper plate 21 and a lower plate 22. The power connection assembly 5 includes a clamping portion 51, a flexible connection portion 52, and a power connection portion 53. The clamping portion 51 is fixed between the upper plate 21 and the lower plate 22 by a fastening bolt 23.

[0023] Through the combination of the clamping portion 51 and the fastening bolt 23, the connection between the conductive plate and the power connection assembly 5 can be achieved without welding or other permanent fixing methods, which makes the installation and disassembly very convenient and fast. The clamping portion 51 tightly presses the upper plate 21 and the lower plate 22 together through the fastening bolt 23 to form a stable contact surface, thereby ensuring good electrical conductivity. This connection method can reduce the contact resistance and reduce the heating phenomenon.

[0024] The flexible connection 5 is a flexible copper strip. Copper is an excellent conductor with low resistivity, meaning it can efficiently transmit current and reduce energy loss. Its flexibility allows it to bend and twist to a certain degree, which helps alleviate stress caused by thermal expansion, contraction due to cooling, or mechanical vibration, thereby reducing the risk of fracture at the connection. The flexible copper strip electrical connection assembly is easier to install than a rigid connection and also facilitates subsequent inspection and maintenance. Its flexibility makes it easier to adjust the electrical connection assembly during assembly to ensure good electrical contact. The power connector 611 of the electrolytic cell is rigidly connected to the power connector 53 of the power connection assembly 5. If the power connector 53 is also rigidly connected to the clamping portion 51, then because the rigid connection does not have the ability to adaptively adjust, in the following circumstances (but not limited to): the power connector 611 of the electrolytic cell itself has a certain degree of skewness or deviation, or the power connectors 611 of different electrolytic cells are relatively skewed or deviated from each other, or the vehicle body 1 is relatively skewed or deviated relative to the electrolytic cell, then the power connector 53 of the power connection assembly 5 cannot be well combined with the power connector 611 of the electrolytic cell, thereby affecting the stable transmission of current.

[0025] The flexible copper strip can achieve adaptive adjustment, which means that even if there is a slight positional offset or mechanical vibration in the electrolytic cell system, the flexible copper strip can achieve a good combination of the power connection part 53 and the power connection head 611 of the electrolytic cell.

[0026] A traction ring 12 is provided on the vehicle body 1. The traction ring 12 can serve as a fulcrum, making it possible to easily push or pull the transverse vehicle body 1, and particularly when the position of the vehicle needs to be frequently moved, the traction ring 12 provides a convenient gripping point.

[0027] like Figure 3 As shown, the vehicle body 1 is provided with a guardrail 13. When the vehicle moves in a narrow space, the guardrail can reduce the possibility of the vehicle colliding with other equipment or structures. The guardrail 13 can also increase the overall rigidity of the vehicle body, making the vehicle more stable.

[0028] like Figure 4 As shown, the on-off switch 4 can connect or disconnect the electrical connection between the first conductive plate 2 and the second conductive plate 3. The on-off switch 4 is provided with a handle 41 for controlling the connection or disconnection. An arc extinguishing device is also provided within the on-off switch 4. It should be noted that the on-off switch 4 in this embodiment is a standard component or a component known to those skilled in the art. Its structure and principles are readily known to those skilled in the art through technical manuals or routine experimental methods.

[0029] Since there are various specifications for the electrolytic cells, there are also corresponding various specifications for this device, which are mainly reflected in the lengths of the first conductive plate 2 and the second conductive plate 3. At the same time, the capacity of this device can be pre-set to skip one cell, or can be pre-set to skip two cells (two adjacent electrolytic cells), or can also be pre-set to skip three cells (three mutually adjacent electrolytic cells), and so on. In this way, it can achieve the maintenance of only one electrolytic cell, or can also achieve the simultaneous maintenance of two adjacent electrolytic cells, or more.

[0030] As an embodiment, as Figure 5 shown, if both the first electrolytic cell 61 and the second electrolytic cell 62 need to be repaired, adjust the position of the vehicle body 1 so that the power connection assemblies 5 of the first conductive plate 2 and the second conductive plate 3 are respectively aligned with the power connection heads 611 of the first electrolytic cell 61 and the third electrolytic cell 63.

[0031] The entire power connection assembly 5 is relatively large in volume, and it is inconvenient to connect and remove. In order to facilitate the disconnection and connection of the power connection assembly 5 and the electrolytic cell power connection head 611, multiple power connection assemblies 5 can be provided. Pull the handle 41, and the on-off switch 4 closes to form a closed circuit. The first electrolytic cell 61 and the second electrolytic cell 62 are short-circuited, and the third electrolytic cell 63 continues to be powered on. When the current needs to be disconnected, the operator operates the handle 41 again, and the on-off switch 4 disconnects, and the circuit is disconnected. This trolley can be applied to the electrolysis workshop in the non-ferrous smelting industry to connect and disconnect DC large current circuits of 30 kA and below, and achieve fast start-stop cell operation. The main purpose of this device is to isolate and skip individual faulty electrolytic cells without interrupting the operation of the entire production line. In this way, even if one or several electrolytic cells need to be repaired, the current can be redirected to other normally working electrolytic cells, thus maintaining the continuous operation of the production line.

[0032] The skipping device designed by the present utility model can not only be used for temporarily cutting off the power when one or several electrolytic cells fail, so as to facilitate the isolation and repair of the faulty cells, but also can achieve a continuous power-off state. The flexibility of this design allows the operator to decide whether to restore the power supply of the electrolytic cell according to the actual production requirements, or to maintain the power-off state during the repair period, thus not affecting the continuous operation of the entire production line.

[0033] The present utility model has been described by way of example above, but the present utility model is not limited to the above specific embodiments. Any modification or variation based on the present utility model belongs to the scope protected by the present utility model.
