[0042] Specifically, the storage cylinder 2 has a drain pipe 21 at the bottom, and a valve 210 is provided on the drain pipe 21. The drain pipe 21 and the storage cylinder 2 are integrally formed. The valve 210 and the drain pipe 21 are fixedly connected by screws. The drain pipe 21 has a screw hole 211 on its outer wall.

[0043] In this invention, the valve 210 helps to block or connect the drain pipe 21, facilitating the discharge of the perfluorohexanone solution inside the storage cylinder 2.

[0044] It should be noted that a connecting plate 3 is provided on the front end face of the fixing base 1 at the position corresponding to the storage cylinder 2. A slot 30 is provided on the connecting plate 3 at the position corresponding to the drain pipe 21. A through hole 300 is provided on the outer wall of the connecting plate 3 at the position corresponding to the screw hole 211. A fixing bolt 301 is provided in the through hole 300. The width of the inner wall of the slot 30 is adapted to the width of the outer wall of the drain pipe 21.

[0045] In this utility model, the fixing bolt 301 passes through the through hole 300 and is threadedly connected to the screw hole 211, so as to realize the stable insertion and installation of the drain pipe 21 of the storage cylinder 2 and the slot 30 on the connecting plate 3, thereby increasing the stability of the assembly.

[0046] Furthermore, the bottom of the connecting plate 3 is provided with a connecting pipe that communicates with the slot 30, and a solenoid valve 31 is provided on the connecting pipe.

[0052] In this invention, the signal line of the temperature sensor 43 is connected to the input terminal of the controller 40. When the temperature is abnormal and reaches the set threshold, the controller 40 sends a signal to the warning light 41 and the alarm 42 through its output terminal, triggering them to sound an alarm. The controller 40 also starts the solenoid valve 31 to open, so that the perfluorohexanone solution inside the storage cylinder 2 enters the spray holder 32 and is sprayed out through the nozzle 320 to achieve the corresponding spraying fire extinguishing effect.

[0053] When using the flammable coal seam integrated fire prevention and extinguishing device of this embodiment, firstly, the controller 40 is installed in the control box 4 with a battery.

Then, the sealing cover 44 is provided with a force point by the pull handle 440, and is inserted into the control box 4 with the cooperation of the sealing gasket and fixed with screws.

[0054] The fixed base 1 is fixedly connected to the mine wall by the positioning bolt 100 passing through the positioning hole 10. When the set threshold is reached according to the signal received from the temperature sensor 43, the controller 40 sends a signal to the warning light 41 and the alarm 42 through its output terminal to trigger them to sound an alarm. The warning light 41 and the alarm 42 are activated to attract the attention of outside personnel and facilitate timely evacuation. The controller 40 also activates the solenoid valve 31 to open, so that the perfluorohexanone solution inside the storage cylinder 2 enters the spray base 32 and is sprayed out through the nozzle 320 to achieve multi-directional spray fire extinguishing.

[0055] When it is necessary to replace the storage cylinder 2, manually close the valve 210, remove the fixing bolt 301, and make it easy to take out the storage cylinder 2 for replacement. Opening the sealing cover 44 helps to facilitate internal maintenance. The overall assembly is convenient to install and is not affected by power outages caused by external force majeure factors.
