When the photovoltaic module 101 is in normal operation, the electric energy generated by the solar panel is transmitted to the grid 102 and the energy storage device 12 through the inverter 11. When the photovoltaic module 101 is on fire, the temperature rise is detected by the recoverable temperature-fixing type temperature-sensing cable 21, the circuit formed by the recoverable temperature-fixing type temperature-sensing cable 21 and the terminal processor 24 is short-circuited, the microcomputer processor 22 transmits the electric signal to the fire-fighting alarm and linkage control host 31, and the acousto-optic alarm lamp 23 is started. The fire alarm and coordinated control host 31 sends signals to the shut-off device 13 and the fire extinguishing device module 4. The shutdown device 13 shuts off the photovoltaic module 101 and stops working, and the fire extinguishing device module 4 starts the electromagnetic valve set 45 to open the spray head 43 for fire extinguishing operation.
As shown in fig. 3, a window 6 is provided on the building exterior wall 5, and a building sill wall 7 is provided under the window 6. The solar cell panel 9 and the vertical direction form an included angle of 30 degrees and are inclined outside the window sill wall 7 of the building, and the solar cell panel is fixed on the cornice 10 through the photovoltaic module 101 mounting bracket 8. The recoverable constant temperature type temperature sensing cable 21 is laid behind the solar cell panel 8 in an S shape. The fire extinguishing system pipeline 42 is arranged at the position of 5cm above the solar cell panel 8, and 5 spray heads 43 are uniformly embedded in the fire extinguishing system pipeline. The spray head 43 can be an open spray head controlled by a solenoid valve set 45 and can spray hydrogel fire extinguishing agent when a fire occurs.
The working principle of the automatic fire alarm and fire-fighting linkage system for the photovoltaic module outside the window sill wall of the building is as follows: when the photovoltaic module 101 normally operates, electric energy generated by the solar panel is input into the energy storage device 12 and the power grid 102 through the inverter 11, and the electric energy is supplied to commercial power on the basis of meeting the self-electricity consumption of the building. When the photovoltaic module 101 is on fire, the temperature of the photovoltaic module backboard rises, a short circuit occurs in a circuit formed by the recoverable temperature-fixing type temperature sensing cable 21 laid on the photovoltaic module backboard and the terminal processor 24, the microcomputer processor 22 transmits a short-circuit electric signal (namely a fire signal) to the fire alarm and linkage control host 31 positioned in the fire control room, and simultaneously, the acousto-optic alarm lamp 23 in the building is started to prompt the resident to withdraw or control the fire in time. After receiving the fire signal, the fire alarm and linkage control host 31 starts the shutdown device 13 through the power controller, so that the fired photovoltaic module stops generating power. Optionally, the photovoltaic module on fire and the photovoltaic module affected by the photovoltaic module on fire stop generating electricity. And simultaneously starting the fire-fighting water pump 44 and the electromagnetic valve group 45, pressurizing and conveying the fire extinguishing agent into the fire extinguishing system pipeline 42, and opening the spray head 43 by the electromagnetic valve group 45 to carry out fire extinguishing operation.
