Description

Technical Field

[0001] The present disclosure relates to the technical field of fire extinguishing equipment, and in particular to a power supply device for a gas fire extinguishing control panel. Background Art

[0002] Gas fire extinguishing systems are widely promoted and applied in places with high fire protection requirements such as precision electronic rooms and data centers. The gas fire extinguishing control panel is one of the important core equipment in the gas fire extinguishing system, which is used to control the injection of fire extinguishing agents in the fire extinguishing system to achieve fire extinguishing. Its power supply requirement is 24 hours uninterrupted power supply, and power supply reliability is crucial to ensure the stable operation of the gas fire extinguishing system.

[0003] At present, the conventional power supply mode of gas fire extinguishing control panel is: the main power supply comes from the dual power supply switch box, and the backup power supply is the built-in lead-acid battery. When the main power supply 220V fails, it can continue to operate by relying on the backup battery.

[0004] The existing mainstream gas fire extinguishing control panel generally has a shortcoming during operation, that is, the monitoring effect of the backup power status of its own lead-acid battery is not perfect. Even if the lead-acid battery fails completely, the gas fire extinguishing control panel still displays the normal status. Firefighting equipment is usually powered by two circuits. When the power supply is reversed and the backup battery fails, the gas fire extinguishing control panel will experience a process of power failure and then power on. This process can easily cause the gas fire extinguishing control panel to malfunction, resulting in the gas extinguishing system spraying incorrectly, causing personnel and equipment losses. Summary of the invention

[0005] Based on this, the purpose of the present disclosure is to improve the stability of the operation of the gas fire extinguishing control panel and avoid mis-spraying of the fire extinguishing system.

[0006] To achieve the above objectives, the present disclosure adopts the following technical solutions:

[0007] A power supply device for a gas fire extinguishing control panel comprises a dual power switching box, a first power supply and a backup power supply, wherein the dual power switching box, the first power supply and the backup power supply are respectively connected to a switching power supply, the first power supply and the backup power supply are connected in parallel, and the switching power supply is connected to a gas fire extinguishing control panel.

[0008] Preferably, the backup power supply includes a plurality of capacitors arranged in parallel.

[0009] More preferably, the number of the capacitors is fourteen.

[0010] Preferably, the backup power supply is provided with a power resistor.

[0011] More preferably, the power resistor limits the charging current of the backup power supply to within 12A.

[0012] Preferably, the backup power supply is provided with a fuse.

[0013] Preferably, the backup power supply is connected to the switching power supply via a wiring terminal, and the wiring terminal is a plug-in type.

[0014] Preferably, the backup power supply is fixed in the gas fire extinguishing control panel by magnetic attraction.

[0015] More preferably, holes are provided at the four corners of the backup power supply, and magnetic internal suction cup studs are installed in the holes, and the backup power supply is adsorbed in the gas fire extinguishing control panel box through the suction cup studs.

[0016] The technical solution claimed in the present disclosure has achieved the following beneficial effects:

[0017] 1) A backup power supply is connected to the original power supply of the gas fire extinguishing control panel. Even in the event of a battery failure, the gas fire extinguishing control panel can be additionally powered when the upper dual power supply switching box is switched back, so that the gas fire extinguishing control panel can continue to operate within the switching time of 3 to 5 seconds, avoiding accidental spraying of the fire extinguishing device during the power-off and power-on process.

[0018] 2) The plug-in terminal blocks and magnetic fixing method enable quick installation and removal between the backup power supply and the original power supply device of the gas fire extinguishing panel. There is no need to modify the original gas fire extinguishing equipment. The backup power supply can be installed in the gas fire extinguishing control panel of various mainstream brands, which facilitates maintenance and replacement and reduces maintenance costs.

The backup power supply includes a plurality of capacitors arranged in parallel, and the number of capacitors can be set to 14 for example, which can provide additional power supply for about 10 seconds to the gas fire extinguishing control panel. The backup power supply is provided with a power resistor, which limits the charging current of the backup power supply to within 12A to reduce the burden of the switching power supply.

[0027] In a preferred structure, the backup power supply is connected to the switching power supply via a wiring terminal. For ease of maintenance, the wiring terminal is preferably a plug-in type (not shown in the figure). In a more preferred structure, the backup power supply is fixed in the gas fire extinguishing control panel by magnetic attraction. Exemplarily, holes can be provided at the four corners of the backup power supply, and internal tooth suction cup studs with strong magnetism (not shown in the figure) can be installed in the holes, and the backup power supply is firmly adsorbed in the gas fire extinguishing control panel box through the suction cup studs.
