Description

Technical Field

[0001] The invention belongs to the technical field of power supply equipment, and in particular relates to a highly safe mobile power supply box. Background Art

[0002] While some mobile power packs exist in the current power supply technology landscape, practical applications present several pressing challenges. These devices often lack effective and reliable overheating, leakage, and overload protection systems. Alternatively, their leakage circuit breakers may be insensitive, and their overload protection may be slow to respond, preventing them from rapidly disconnecting the circuit in the event of an electrical fault. This leads to a high risk of electric shock and frequent electrical fires during use, posing a significant threat to the safety of personnel, equipment, and property. Summary of the Invention

[0003] In order to solve the above problems of the prior art, the present invention provides a highly secure mobile power supply box, which has all-round safety protection and effectively prevents various electrical faults from occurring.

[0004] The present invention is achieved through the following technical solutions: A highly secure mobile power supply box comprises a box body and an insulating base plate, wherein the box body is arranged on the insulating base plate, and universal wheels are arranged at the bottom of the insulating base plate; a leakage circuit breaker, an overheating protector, an air switch and a power cord are arranged inside the box body; a current display, a knife switch and a power output interface are arranged on the front panel of the box body; one end of the power cord is connected to the power output interface via the leakage circuit breaker, the overheating protector, the current display, the knife switch and the air switch in sequence, and the leakage circuit breaker is a leakage circuit breaker based on zero-sequence current detection technology.

[0005] Preferably, the power output interface includes a three-phase socket, a single-phase socket and a power terminal.

[0006] Furthermore, the circuit breaker includes a three-phase circuit breaker and a single-phase circuit breaker. The knife switch is connected to the three-phase socket via the three-phase circuit breaker, and the knife switch is connected to the single-phase socket via the single-phase circuit breaker.

[0007] Furthermore, the power terminals include high-current wiring terminals and precision wiring terminals equipped with filtering circuits.

[0008] Preferably, a rainproof cover is installed on the top of the box.

[0009] Preferably, a telescopic pull rod is provided on the rear panel of the box.

[0010] Preferably, the box body is provided with a rotating winding drum for storing the power cord on the side panel.

[0011] Preferably, a rotating handle is provided on the rotating winding drum.

[0012] Preferably, the leakage circuit breaker is a leakage circuit breaker with a rated current of 100A or an operating current of 30mA.

[0013] Preferably, a voltage display is also provided on the front panel of the box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The mobile power box of the present invention has all-round safety protection. The overheat protector uses a thermistor to monitor the temperature inside the box in real time. When the temperature exceeds 70°C, it immediately triggers heat dissipation and power-off protection. The leakage circuit breaker uses cutting-edge zero-sequence current detection technology, which can quickly cut off the circuit when the leakage current reaches 30mA, with a response time of less than 0.1 seconds. The circuit breaker uses an intelligent chip to monitor current changes. When the load current exceeds the rated value by 10%, the protection mechanism is quickly activated to prevent the equipment from burning due to overload. The current display is used to display the power supply current in real time. The present invention has established a comprehensive, multi-level safety protection system to effectively prevent all kinds of electrical failures.

[0015] Furthermore, the mobile power box of the present invention adopts a multifunctional integrated design. Inside the power box, a wide variety of power output interfaces are integrated. Sockets and power terminals of varying specifications can accommodate a wide range of industrial equipment, from common small power tools to large production machinery. This invention addresses the problem that traditional power boxes, due to their limited functionality, can only accommodate basic power equipment. This makes them unable to provide comprehensive and adaptable power support in complex power environments, such as the simultaneous operation of multiple types of equipment in industrial production, the need to adapt to a variety of specialized instruments in field operations, and the diverse power demands of different construction stages at construction sites.

[0016] Furthermore, the present invention installs a rainproof cover on the top of the box body, which can play a rainproof role and avoid damage to components caused by rain.

[0017] Furthermore, a telescopic pull rod is provided on the rear panel of the box of the present invention, and the height can be freely adjusted according to the height of the user. The operation is convenient, so that the power box can be easily moved and accurately positioned in various work sites, which significantly improves the convenience and flexibility of on-site operations.

[0018] Furthermore, a rotating winding drum for storing the power cord is provided on the side panel of the box of the present invention, ensuring that the power cord can be stored and used conveniently and quickly, solving the problem that the power cord of the existing power box is placed arbitrarily and has no special winding device, which easily causes the cable to be entangled, damaged, and affects the service life.
