Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to an outdoor standby power supply cabinet. Background Art

[0002] Traffic lights, street lights, monitors and other electronic infrastructure are all powered by the power grid. If the power grid fails partially or completely due to natural disasters or other factors, it will cause traffic chaos in the area and the area will be plunged into darkness at night. Therefore, in the prior art, a backup power supply system is usually provided to ensure the normal operation of the equipment. However, the existing backup power supply system uses a built-in battery, so the battery capacity determines the operating time. Once the power grid is not repaired and the built-in battery is exhausted, the electronic infrastructure is still at risk of power outages. Utility Model Content

[0003] Based on the above problems, the utility model aims to provide an outdoor backup power supply cabinet.

[0005] By adopting the above technical scheme, when the mains power grid is abnormal, the dual power supply automatic switching switch controls the circuit switching to achieve uninterrupted power supply to the power supply cabinet, thereby maintaining the operation of electronic infrastructure such as transportation. At the same time, compared with the built-in backup power supply system that sets a large number of backup power supplies and adopts replaceable backup power supply components, the technical scheme of the utility model is conducive to the miniaturization of the backup power supply cabinet and prolonging the continuous working time of the power supply cabinet during maintenance time, and has higher stability. At the same time, a trolley is used to facilitate the backup power supply component to be pulled out of the box for replacement and disassembly, which is easy to use. At the same time, it adopts the plug-in combination with the power terminal group, and the wires of the A-line power grid and the B-line power grid are all arranged in the back cavity, which is clearer during assembly, with high efficiency and high safety.

[0006] This embodiment is further configured as follows: a mounting frame is provided on the trolley, the mounting frame includes an electric pushing frame and a placement frame, the placement frame is arranged above the electric pushing frame, a limiting portion for positioning the backup power supply component is provided at the front end of the placement frame, a control mechanism and a power monitoring mechanism for monitoring the power of the backup power supply component are provided in the front cavity, the backup power supply component is provided with a quick-connect socket, the power monitoring mechanism is electrically connected to the quick-connect socket through a cable, and the control mechanism is electrically connected to the power monitoring mechanism and the electric pushing frame respectively.

[0007] By adopting the above technical solution, when the power monitoring mechanism monitors that the power of the backup power supply component numbered n is lower than the limit value, the control mechanism sends a command to the electric push frame numbered n+1 to drive the backup power supply component numbered n+1 to move backward and connect to the corresponding socket, and then the control mechanism sends a command to the electric push frame numbered n to drive the backup power supply component numbered n to move forward and disconnect from the corresponding socket. The connection is switched automatically throughout the process, avoiding manual plugging, unplugging, pushing and pulling by staff, thereby protecting the safety of staff to a certain extent. At the same time, a limit part is set on the placement frame to facilitate the rapid assembly of the backup power supply component.

[0008] This embodiment is further configured as follows: a positioner and a signal transmission mechanism are also provided in the front cavity, and the positioner and the signal transmission mechanism are electrically connected to the control mechanism respectively.

[0009] By adopting the above technical solution, when the power monitoring mechanism detects that only one group of the backup power supply components has power left, the control mechanism controls the signal transmission mechanism to transmit a warning signal of the location information and number information of the power cabinet to the control terminal, so that the emergency repair personnel can quickly understand the information and replace the backup power supply components, thereby ensuring the basic electricity supply for transportation and obtaining more maintenance time.

[0010] This embodiment is further configured as follows: the box body also includes an upper cavity, in which a battery, a controller, an inverter and more than two charging cables are arranged, the A-line power grid is electrically connected to the battery via the inverter, one end of the charging cable is connected to the battery through the controller, and the other end is arranged in the outer cavity and detachably connected to the backup power supply assembly, and the power monitoring mechanism is electrically connected to the controller.

[0011] By adopting the above technical solution, when the city power is normal, the battery is charged through the inverter. When the power monitoring mechanism determines that the backup power supply component is insufficient, the controller charges the backup power supply component through the battery. The charging is converted by the battery, which has higher stability and longer service life of the backup power supply component.

[0012] This embodiment is further configured as follows: a solar panel is arranged on the top of the box, and the solar panel is electrically connected to the battery.

[0013] By adopting the above technical solution, the outdoor environment is fully utilized, the charging methods are diversified, more environmentally friendly, and double protection is provided to avoid the situation where the repair personnel fail to replace the backup battery components in time when the city power is unstable, and the solar panels serve as an auxiliary power source.
