The invention discloses a double-pack battery with an anti-circulation function for a forklift battery and a control method of the double-pack battery, and relates to the field of electric forklift batteries. The double-pack battery comprises two battery packs, each battery pack is integrated with a battery management system, an anti-circulation control module, a switching relay, a discharge relay and other core components, local area network communication is formed between the battery management systems of the two battery packs and between the battery management systems of the two battery packs and a vehicle VCU, and a discharge positive electrode and a discharge negative electrode are connected to a vehicle load after being connected in series through a power cable. A discharging main loop, a switching discharging loop, a charging loop and a heating loop are arranged in a single battery pack, a temperature sensing detection circuit is arranged in an anti-circulation control module, and a Hall current sensor collects current of the switching loop in real time and limits discharging power. According to the control method, the standby battery pack is awakened when the power supply battery pack is low in electric quantity or breaks down, and after self-inspection and instruction interaction, double-pack battery non-inductive switching is achieved through sequential control of the switching relay and the discharging relay and protection of the anti-circulation module.

This invention provides a visual bearing lubrication device for mills, belonging to the field of mill technology. The device includes a bearing housing, a bearing, and a bearing cover. The bearing cover has a main oil inlet, a spare oil inlet, and a double-sealed hydraulic quick-change connector. The side wall of the bearing housing has an observation window and a self-cleaning, pressure-resistant coated glass. The oil drain is connected to a filter assembly. This invention achieves continuous oil supply without stopping the mill through one-button switching between dual oil circuits. The pressure-resistant glass provides direct monitoring of the bearing lubrication status and oil level, and the filter assembly filters out impurities from the returned oil. This ensures continuous mill production, reduces bearing wear, improves the stability of the lubrication system, and lowers maintenance costs.

This application belongs to the field of welding technology and discloses a conductive tip disassembly and feeding device and a conductive tip replacement equipment. The conductive tip disassembly and feeding device includes a conductive tip disassembly and feeding mechanism, a conductive tip feeding mechanism, and a position switching mechanism. The position switching mechanism drives the conductive tip feeding mechanism to move along a first horizontal direction, enabling the feeding mechanism to have a loading position for delivering new conductive tips to the disassembly and feeding mechanism and a waiting position to avoid the disassembly and feeding mechanism. The disassembly and feeding mechanism removes the conductive tip from the welding torch or installs a new conductive tip onto the welding torch. Only one disassembly and feeding mechanism is needed to achieve the disassembly and assembly of the conductive tip, allowing for disassembly and assembly at the same workstation, improving work efficiency. Furthermore, both the feeding mechanism and the position switching mechanism are located below the disassembly and feeding mechanism, making the overall structure more compact and space-saving. This conductive tip replacement equipment not only has high work efficiency but also a compact structure and small space occupation.

The invention provides a replacing device and a replacing system.The replacing device comprises a picking head, a placing mechanism and a moving mechanism, the placing mechanism comprises a placing base and a locking piece, the placing base is provided with a containing groove used for containing the picking head, the locking piece is arranged on the placing base and used for locking or releasing the picking head, and the moving mechanism comprises a mechanical arm and a connecting part; the connecting part is fixed to one end of the mechanical arm, the connecting part is used for being connected with the picking head, when the locking piece releases the picking head, the mechanical arm mechanism is connected with the picking head through the connecting part, and when the locking piece locks the picking head, the mechanical arm mechanism can move so that the connecting part can be separated from the picking head. Through automatic locking or releasing of a locking piece of the placing mechanism, automatic transferring of a mechanical arm of the moving mechanism and automatic butt joint of connecting parts, manual intervention of replacement and storage of the picking head is not needed in the whole process, errors caused by manual operation are avoided, the problem of equipment shutdown during manual replacement is solved, and continuous operation of a production line is achieved.

The application provides a mobile megawatt-level energy storage battery cluster monitoring and fault isolation system based on eight independent BMS, which is applied to a mobile energy storage vehicle configured with peripheral electrical equipment and eight groups of energy storage battery packs. The system comprises eight independent BMS modules, eight independent high-voltage disconnection switches, a full-line linkage communication bus and a centralized control hub. When any BMS module detects a fault of the corresponding energy storage battery pack, a shutdown instruction is issued to control the corresponding high-voltage disconnection switch to trip, so as to isolate the faulty battery pack from the common DC main bus. The centralized control hub then acquires the number of the remaining normal energy storage battery packs, dynamically recalculates the remaining total capacity and synchronizes it to the peripheral electrical equipment, and the peripheral electrical equipment adaptively adjusts the output upper limit of the total power. The application realizes the physical isolation of a single group of faulty batteries and the adaptive derating of the system capacity, and guarantees the continuous external power supply of the remaining normal battery packs.

The invention relates to an electrical box system and a control method. The electrical box system comprises a power supply and at least two working modules. The at least two working modules are arranged in parallel, and each working module is electrically connected with the power supply. Each working module comprises a load unit and a pre-charging unit which are connected in series. The first end of the pre-charging unit is electrically connected with the positive electrode of the power supply, the second end of the pre-charging unit is electrically connected with the first end of the load unit, and the second end of the load unit is electrically connected with the negative electrode of the power supply. The pre-charging unit can be switched between a first working state and a second working state, in the first working state, the power supply pre-charges the load unit, and in the second working state, the power supply supplies power to the load unit to enable the load unit to work normally. The pre-charging units are correspondingly arranged for the multiple groups of loads, the redundancy of the system can be remarkably improved, when any branch fails, the other branch can be quickly connected, the power supply continuity of the main loop of the electrical box is guaranteed, and the working stability of the electrical box system is improved.
