Description

Technical Field

[0001] The invention relates to an ultraviolet photoelectric linkage digital controllable aerosol fire extinguishing device. Background Art

[0002] At present, most fire extinguishers on the market are triggered by temperature-sensitive wires, which are analog triggers with low accuracy. In addition, a charged gas generator is installed in the extinguishing agent in the fire extinguisher for a long time. The charged gas generator cannot be turned off during transportation or installation, and the gas generator may be accidentally triggered. Therefore, the probability of false triggering is relatively high. When the fire extinguishing device is installed in a relatively hidden place, such as in a cable trench, the power of the gas generator cannot be detected, and it is impossible to determine whether the fire extinguishing device is effective. If it is not replaced, the fire may not be extinguished. If it is replaced, it may cause unnecessary waste. Summary of the invention

[0003] In order to solve the above technical deficiencies, the present invention provides an ultraviolet photoelectric linkage digitally controllable aerosol fire extinguishing device, which effectively avoids false triggering.

[0004] The present invention is achieved by the following measures:

[0005] A ultraviolet photoelectric linkage digital controllable aerosol fire extinguishing device comprises a cylindrical fire extinguisher shell, the fire extinguisher shell is filled with aerosol fire extinguishing agent and is provided with a gas generator, the top of the fire extinguisher shell is threadedly connected with a cylindrical barrel, an integrated circuit board is provided in the barrel, a generator trigger module, a microprocessor and a communication module connected to the microprocessor signal, a power supply battery, and a switch element are integrated on the integrated circuit board, a signal input end of the microprocessor is externally connected to an ultraviolet detector through a wire, the ultraviolet detector is connected to the power supply battery, the power supply battery, the switch element, and the generator trigger module are connected to form a closed loop through wires, a control signal output end of the microprocessor is connected to the switch element, and the generator trigger module signal is connected to the gas generator.

[0006] The cylinder is provided with an aviation socket, which is electrically connected to a power supply battery and a signal input terminal of a microprocessor, and the ultraviolet detector is connected to an aviation plug matching the aviation socket through electric wires.

[0007] The power supply battery is connected to a power display unit via a wire, and a manual switch is connected in series to the wire.

[0008] The communication module is a wireless communication module or a wired communication module, and the switch element is a transistor or a field effect transistor.

[0009] The beneficial effects of the present invention are: the fire situation is monitored in real time with high accuracy through the ultraviolet detector, and the generator trigger module is not powered at normal times, thus avoiding false triggering during transportation or installation. The power status can also be checked regularly to effectively determine whether the device is effective, thus avoiding waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0014] like Figure 1 , 2 As shown, a UV photoelectric linkage digital controllable aerosol fire extinguishing device comprises a cylindrical fire extinguisher housing 1, the fire extinguisher housing 1 is filled with aerosol fire extinguishing agent and is provided with a gas generator 2, the top of the fire extinguisher housing 1 is threadedly connected with a cylindrical barrel 4, the barrel 4 is provided with an integrated circuit board 3, the integrated circuit board 3 integrates a generator trigger module, a microprocessor, and a communication module connected to the microprocessor signal, a power supply battery, and a switch element, the signal input end of the microprocessor is externally connected to an ultraviolet detector 5 through a wire, the ultraviolet detector 5 is connected to the power supply battery, the power supply battery, the switch element, and the generator trigger module are connected to form a closed loop through wires, the control signal output end of the microprocessor is connected to the switch element, and the generator trigger module signal is connected to the gas generator 2. An aviation socket is provided on the barrel 4, the aviation socket is electrically connected to the power supply battery and the signal input terminal of the microprocessor, and the ultraviolet detector 5 is connected to an aviation plug matching the aviation socket through a wire.

[0015] The power supply battery is connected to the power display unit through a wire, and a manual switch is connected in series on the wire. The communication module adopts a wireless communication module or a wired communication module, and the switch element adopts a transistor or a field effect tube.

[0016] During transportation or installation, the aviation plug of the ultraviolet detector 5 can be unplugged. At this time, the switch element is in the disconnected state, the generator trigger module is not powered, and even if static electricity is generated, the gas generator 2 cannot be triggered, thereby avoiding false triggering. When the device is installed in a hidden place such as a cable trench, when the ultraviolet detector 5 detects flames or heat generation, the generated signal is sent to the microprocessor, and the microprocessor controls the switch element to conduct, so that the generator trigger module triggers the gas generator 2, and the gas generator 2 generates gas to spray the aerosol fire extinguishing agent from the fire extinguisher housing 1, thereby achieving fire extinguishing. After a certain time, the staff can unscrew the cylinder 4, use an instrument to detect the power of the power supply battery, or directly close the manual switch, and display the current power of the power supply battery through the power display unit, so as to determine whether to replace the power supply battery or the fire extinguishing device.
