Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:
[0032] Embodiment 1: In order to solve the problem that the water inside the water tank 2 cannot be quickly found after it is used up in the prior art, see Figure 2 and Figure 5-Figure 6As shown, the display light 13 is arranged at the upper end of the water tank 2, and the interior of the water tank 2 is filled with water, and a connecting mechanism is arranged inside the water tank 2, and the connecting mechanism connects the display light 13 to the circuit through the arrangement of the side contact 21 and the middle contact 23, and the side contact 21 is located in the middle and left side of the display light 13; the middle floating plate 16 is located inside the water tank 2, and the upper end of the middle floating plate 16 is adhered with a counterweight 15; the left and right sides of the inside of the counterweight 15 are slidably connected with side floating plates 18, and the outer side of the side floating plate 18 is arranged in an arc-shaped structure, and a connecting spring 17 is arranged between the inner side of the side floating plate 18 and the counterweight 15, and the connecting mechanism includes a fixed The rope 14 is installed on the upper end of the counterweight 15, and the insulating block 19 is slidably connected to the left side of the water tank 2, and the insulating block 19 is provided on the side of the insulating block 19 close to the side contact 21, and a support spring 24 is provided between the other side of the insulating block 19 and the water tank 2; the power supply 20 is installed on the lower side of the water tank 2, and wires are installed between the power supply 20, the side contact 21 and the display light 13, and the insulating plate 22 is slidably connected to the inside of the water tank 2, and the middle contact 23 is provided at the lower end of the insulating plate 22; the upper end of the insulating plate 22 is welded with a connecting plate 25, and a connecting spring 17 is provided between the connecting plate 25 and the lower part of the water tank 2;
[0033] When there is water inside the water tank 2, the middle floating plate 16 will float on the water surface. When the water tank 2 is filled with water, the water will cause the middle floating plate 16 to move upward. The upward movement of the middle floating plate 16 will drive the side floating plates 18 to move upward synchronously. Since the outer sides of the side floating plates 18 are in an arc-shaped structure, when the side floating plates 18 move upward to contact with the two sides of the water tank 2, the inner sides of the water tank 2 will push the opposite side floating plates 18, and the side floating plates 18 move to the middle position. Due to the weight of the water, the connecting plate 25 will move downward, and the connecting plate 25 will drive the insulating plate 22 to move downward.

A water pump is arranged inside the water tank 2, and the nozzles 9 are connected to the water pump by raising the conduit; when the water pump is turned on, the water in the water tank 2 can be sprayed through the conduit and the nozzle 9 to one meter in front of the fire door 6, so as to cool down and improve the fireproof partition effect. Through the above process, the problems existing in the prior art that the fire situation cannot be observed in time, the fire door 6 can be opened and closed remotely, and the fire door 6 is difficult to open and close after being closed, resulting in the failure of personnel to escape in time are solved;
[0036] Embodiment 3: This embodiment can make the fire door 6 intelligently open and close or open and close through the gas control box 11 alternately. A two-way cylinder 10 is arranged on the upper inner side of the fire door 6. An intelligent control box 12 and an air control box 11 are arranged on the left and right sides of the interior of the firewall 3, respectively. An AI camera 7 is arranged on the front above the door frame 4, and the AI camera 7 can monitor the fire situation in time and transmit the signal to the intelligent control box 12.

[0037] When a fire occurs in the mine and the fire has not spread to the fire door 6, the workers in the mine can escape directly through the fire door 6; when the temperature sensor 5 and the smoke sensor 8 sense the fire signal, they will feed the signal back to the intelligent control box 12. After receiving the signal, the intelligent control box 12 will send an alarm to the relevant department and start the automatic closing device. The fire door 6 opens and closes faster than the fire alarm is triggered to prevent the spread of fire to the greatest extent. This is an intelligent perception process. When another mine worker comes to the closed fire door 6, the AI camera 7 can automatically recognize the person and open the fire door 6. In order to avoid emergencies when the fire door 6 is closed, a manual opening and closing process can also be performed through the air control box 11. In order to ensure real-time monitoring of the fire situation, the images monitored by the AI camera 7 are synchronized to the large screen of the monitoring center in real time, and the fire door 6 is remotely controlled.
