Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and particularly to a large-capacity mobile fast-charging device with a switchable power supply for power transmission and distribution projects. Background Art

[0002] A mobile fast-charging device is a mobile power supply device designed specifically for power transmission and distribution projects, which has the capabilities of large-capacity energy storage, fast charging, and switchable power supply. It can flexibly switch between different power supply powers to ensure the continuous and stable operation of the device in various power environments, and at the same time meet the demand for rapid replenishment of large-capacity power.

[0003] During the use of power transmission and distribution projects, a large-capacity mobile fast-charging device is required. It is found during the use that the existing technologies have the following deficiencies: First, most of the existing mobile fast-charging devices adopt an integrated installation method. The internal battery pack and charging pile components are tightly installed in a closed housing, and there is a lack of clear separation between these components. Therefore, it is easy to cause the circuit lines of the internal battery pack and charging pile components to be cross-distributed and the layout to be chaotic. Once a failure occurs, it usually requires professional technicians to disassemble and detect. This not only takes time and effort but also may cause more damage due to misoperation, increasing the downtime and reducing the maintenance efficiency; Second, with the continuous development of fast-charging technologies, power transmission and distribution projects require more updated designs for mobile fast-charging devices. The devices need to be continuously upgraded to meet higher charging efficiency, better safety, or lower energy consumption requirements. Under the integrated design, device upgrades often mean the replacement of the entire system, which is costly and wasteful of resources; Third, the protective effect of the housing is limited. If it is damaged by bumps, it is easy for the internal parts of the device to be damaged, and the protective effect is not good. During the use of power transmission and distribution projects, it is often necessary to transport the mobile fast-charging device to multiple locations. Therefore, accidents are likely to occur during multiple transportation processes. In view of the deficiencies of the existing technologies, the present invention provides a large-capacity mobile fast-charging device with a switchable power supply for power transmission and distribution projects to solve the above problems.

Embodiment 2

[0034] An embodiment of the present invention discloses a large-capacity mobile fast charging device with a switchable power supply for power transmission and distribution projects. According to the attached Figures 1-11 As shown in the figure, it includes a carrier 1, an electrical connection module 2, a battery pack module 3, a charging pile module 4, a positioning column 5, multiple groups of positioning seats 6, a locking unit 7, and a total protective cover 8; The carrier 1 is used to carry each module of the device; The electrical connection module 2 is arranged on the carrier 1, and a modular socket 21 is provided on the electrical connection module 2; The battery pack module 3 is arranged on the electrical connection module 2 in a snap-fit manner. The battery pack module 3 includes: The battery pack main body 31 is used to store electric energy; The first cover body 32 is arranged outside the battery pack main body 31; The first modular plug 33 is arranged on the first cover body 32 and is connected to the battery pack main body 31. The first modular plug 33 is plugged into the modular socket 21; The charging pile module 4 is arranged on the electrical connection module 2 in a snap-fit manner. The charging pile module 4 includes: The charging pile main body 41 is used to supply energy to external devices; The second cover body 42 is arranged on the outside of the charging pile main body 41; The second modular plug 43 is arranged on the second cover body 42 and is connected to the charging pile main body 41. The second modular plug 43 is plugged into the modular socket 21; The positioning column 5 is arranged on the electrical connection module 2; Multiple groups of positioning seats 6 are respectively arranged on the first cover body 32 and the second cover body 42, and the multiple groups of positioning seats 6 are engaged with the positioning column 5; The locking unit 7 is arranged on multiple groups of positioning seats 6 and is used to lock the positioning column 5; The total protective cover 8 is movably snap-fitted on the carrier 1.

[0035] The total protective cover 8 is provided with a fire protection unit 10. The fire protection unit 10 includes: The electric fire extinguisher 1001 is installed on the general protective cover 8; the electric fire extinguisher 1001 uses an environment-friendly fire extinguishing agent, such as dry powder or gas fire extinguishing agent, which has no pollution to the environment; The smoke sensor 1002 is installed on the electric fire extinguisher 1001; the smoke sensor 1002 has high sensitivity and can quickly respond to the smoke changes in the environment; The fire extinguishing agent nozzle 1003 is installed on the electric fire extinguisher 1001; The main controller 1004 is installed on the electric fire extinguisher 1001 and is connected to the smoke sensor 1002.

[0036] Through the design of the fire protection unit 10, this device can conveniently start fire extinguishing and fire protection in the first time when a fire and smoke occur due to faults or short circuits in the battery pack module 3 and the charging pile module 4, reducing losses. The principle is as follows: The smoke sensor 1002 monitors the smoke particles in the environment in real time. Once it detects that the smoke concentration exceeds the preset threshold, it immediately transmits an alarm signal to the main controller 1004. After receiving the alarm signal from the smoke sensor 1002, the main controller 1004 immediately processes and analyzes the signal to judge whether it is necessary to start the fire extinguishing program. If the main controller 1004 judges that it is necessary to start the fire extinguishing program, it will send a start signal to the electric fire extinguisher 1001. After receiving the signal, the electric fire extinguisher 1001 immediately starts and sprays the fire extinguishing agent towards the fire source. The electric fire extinguisher 1001 sprays out with a specific pressure through the fire extinguishing agent nozzle 1003, covering the fire source and isolating oxygen, so as to achieve the effect of extinguishing the fire, prevent the fire source from further expanding, and reduce losses.

[0037] A fire protection notch 321 is opened on the first cover body 32, and the fire protection notch 321 is aligned with the position of the fire extinguishing agent nozzle 1003.
