[0022] The inner wall of the connecting pipe 3 is equipped with a level sensor 16 for monitoring the water level inside the connecting pipe 3. Specifically, the connecting pipe 3 includes a U-shaped pipe in the middle and horizontal pipes connected to both ends of the U-shaped pipe. The level sensor 16 is located on the upper inner wall of the U-shaped pipe on the side near the sealed box 2. A controller 15 connected to a solenoid valve is fixedly installed on the first water tank 4 for controlling the solenoid valve. The level sensor 16 is communicatively connected to the controller 15. A water pump 18 for pumping water out of the first water tank 4 is fixedly installed inside the bottom side of the first water tank 4. The input end of the water pump 18 is connected to the inner cavity of the first water tank 4, and the output end of the water pump 18 is connected to the inner cavity of the second water tank 4 through a drain pipe 20. The water pump is communicatively connected to the controller. Specifically, a water suction pipe 19 is fixedly connected to the input end of the water pump 18, and one end of the water suction pipe 19 extends into the inner cavity of the first water tank 4. The output end of the water pump 18 is fixedly connected to a drain pipe 20 for transporting water from the inner cavity of the first water tank 4 to the inner cavity of the second water tank 8. One end of the drain pipe 20 extends into the inner cavity of the second water tank 8. Through the coordinated use of the water pump 18, the suction pipe 19, and the drain pipe 20, when the water pressure in the inner cavity of the first water tank 4 is too high, the water pump 18 is started. With the cooperation of the water pump 18 and the suction pipe 19, the water in the inner cavity of the first water tank 4 is drawn out and discharged into the inner cavity of the second water tank 8 through the drain pipe 20, thereby reducing the water pressure in the inner cavity of the first water tank 4 and preventing the water pressure in the inner cavity of the first water tank 4 from being too high and entering the inner cavity of the sealed box 2. When the level sensor 16 detects that the water level inside the connecting pipe 3 is too high, it transmits the signal to the controller 15. The controller 15 then controls the solenoid valve on the surface of the outlet pipe 17 to close it, and then starts the water pump 18. The water pump 18, in conjunction with the pumping pipe 19, draws water out of the first water tank 4 and discharges it into the second water tank 8 through the drain pipe 20. When the level sensor 16 detects that the water level inside the connecting pipe 3 is too low, it transmits the information to the controller 15. The controller 15 then opens the solenoid valve on the surface of the outlet pipe 17 and shuts down the water pump 18, thus providing a double guarantee for maintaining the balance between gas pressure and water pressure.
[0023] In summary, when using this coke oven gas pipeline water seal device, one end of the connecting pipe 3 is first inserted into the inner cavity of the sealing box 2, and the other end is inserted into the inner cavity of the first water tank 4. When gas leaks inside the pipeline body 1, it enters the inner cavity of the connecting pipe 3 through the sealing box 2, pushing water from the inner cavity of the connecting pipe 3 into the inner cavity of the first water tank 4, causing the water level in the first water tank 4 to rise. This causes the slider 7 to move upward, which in turn pushes the movable plate 14 to move, causing the connecting rod 13 to move and the baffle 12 to move upward, bringing the baffle 12 into contact with the trigger switch 11. The trigger switch 11 then opens the solenoid valve on the surface of the water outlet pipe 17, allowing water from the inner cavity of the second water tank 8 to enter the inner cavity of the first water tank 4. This increases the water pressure in the inner cavity of the first water tank 4, maintaining a balance between the gas pressure and the water pressure. When the water pressure in the inner cavity of the first water tank 4 increases to exceed the gas pressure, the slider 7 moves downward. When the baffle 12 and the trigger switch 11 are no longer in contact, the trigger switch 11 is released, and the solenoid valve is closed, thus achieving a balance between gas pressure and water pressure. When the level sensor 16 detects that the water level inside the connecting pipe 3 is too high, it transmits the information to the controller 15. The controller 15 controls the solenoid valve on the surface of the outlet pipe 17 to close it, and then starts the water pump 18. With the cooperation of the water pump 18 and the water suction pipe 19, the water inside the first water tank 4 is pumped out and discharged into the second water tank 8 through the drain pipe 20. When the level sensor 16 detects that the water level inside the connecting pipe 3 is too low, it transmits the information to the controller 15. The controller 15 opens the solenoid valve on the surface of the outlet pipe 17 and shuts down the water pump 18, thus providing a double guarantee for maintaining a balance between gas pressure and water pressure, and making it more convenient to maintain a balance between gas pressure and water pressure.
