[0041] Dust cleaning operation:

[0042] When the staff needs to maintain the fireproof door lock in the mall, the staff first fills the built-in lithium battery of the cleaning vehicle 1 with electricity, and then pushes the cleaning vehicle 1 to the fireproof door. The staff opens the fireproof door, turns on the power of the cleaning vehicle 1, and pushes the cleaning vehicle 1 into the fireproof door lock. When the first cleaning brush 211 and the third cleaning brush 231 correspond to the position of the fireproof door lock, stop. At this time, the device program controls the first motor 21 and the third motor 23 to start, and the first motor 21 and the third motor 23 start to rotate and drive the first cleaning brush 211 and the third cleaning brush 231 to rotate. The air compressor 41 starts to spray compressed air from the first cleaning nozzle 411. The device program sets the rotating speed of the first motor 21 and the third motor 23 to V3, and the cleaning time to T1. The first cleaning brush 211 and the third cleaning brush 231 rotate at high speed to clean the dust on the surface of the fireproof door lock and the adjacent door panel area, and preliminarily clean the dust and sand adhered to the fireproof door lock. When the cleaning time T3 is reached, the device program controls the first motor 21, the third motor 23, and the air compressor 41 to stop, and controls the next step to operate.

[0043] At this time, the staff pushes the cleaning vehicle 1 inward until the second cleaning brush 221 and the fourth cleaning brush 241 correspond to the position of the fireproof door lock. Then the device program controls the second motor 22 and the fourth motor 24 to start, and the water tank 42 built-in pump starts. The fifth electric valve 432 is closed and the sixth electric valve 433 is opened. The water tank 42 pressurizes the water and pumps it into the second pipeline 43 to spray it from the second cleaning nozzle 421 in the form of water mist onto the fireproof door lock. The device program sets the rotating speed of the second motor 22 and the fourth motor 24 to V1, and the cleaning time to T1. The second cleaning brush 221 and the fourth cleaning brush 241 rotate at low speed and cooperate with the water sprayed from the second cleaning nozzle 421 to perform water washing and dust removal operation, so as to prevent stubborn dust stains from remaining on the fireproof door lock and improve cleaning efficiency. When the cleaning time T1 is reached, the device program controls the second motor 22 and the fourth motor 24 to close, and the water tank 42 built-in pump and the sixth electric valve 433 to close. Then the device program controls the air compressor 41 to start. The device program sets the blowing time to T2. The air compressor 41 sprays compressed air from the first cleaning nozzle 411 onto the fireproof door lock to dry and blow the fireproof door lock. When the blowing time T2 is reached, the device program controls the next step to operate.

[0044] By the cooperation of four groups of electric motors and four groups of cleaning brushes, when the daily maintenance operation of the fireproof door lock is performed, two groups of cleaning brushes are used to blow out compressed air from the air blower 41 to perform dust cleaning operation, at this time, the two groups of cleaning brushes are in dry state, and the floating dust and sand are preliminarily brushed off, and then the other two groups of cleaning brushes are used to perform dust cleaning operation with clean water, at this time, the two groups of cleaning brushes used are in wet state, and the sand is cleaned more deeply, realizing dry and wet separation of dust cleaning operation, the four groups of cleaning brushes will not pollute each other, and the fireproof door lock can be continuously cleaned without cleaning the cleaning brushes, and the cleaning is more thorough, and after the cleaning is finished, the fireproof door lock is dried to prevent residual water stains from causing rust of the fireproof door lock.

[0045] Lever detection operation:

[0046] When the above operation is completed, the device program control performs lever detection operation, the device program control air compressor 31 starts, the worker controls the device program to open the corresponding electric valve (first electric valve 321, second electric valve 322, third electric valve 323) according to the position of the fireproof door lock installation, the corresponding telescopic cylinder will be extended outward, at this time, the device program detects the signal value of the pressure sensor on the three groups of telescopic cylinders and compares it with the set value, the device program sets the pressure value as X1, if the signal value of the pressure sensor is less than X1, the device program has no operation, the device program judges that the lever of the fireproof door lock is not rusted and can be used normally, if the signal value of the pressure sensor is greater than X1 and less than 2X1, the device program judges that the rust degree of the lever of the door lock is light, if the signal value of the pressure sensor is greater than 2X1, the device program judges that the rust degree of the lever of the door lock is heavy

[0047] When the device program judges that the rust degree of the lever of the door lock is light, at this time, the device program controls the water tank 42 built-in pump to start, the fourth electric valve 431, the fifth electric valve 432 and the sixth electric valve 433 are all opened, the WD-40 rust remover in the rust remover storage chamber 423 is sprayed in the form of water mist from the second cleaning nozzle 421 to the fireproof door lock after being pressurized by the water tank 42 built-in pump, at this time, the device program repeats the above lever detection operation, if the device program detects that the signal value of the pressure sensor is less than X1, the device program has no operation,

[0048] If the device program detects that the signal value of the pressure sensor is still greater than X1 and has not decreased significantly, the WD-40 rust remover in the rust remover storage chamber 423 is sprayed again from the second cleaning nozzle 421 in the form of water mist onto the fire door lock through the built-in pump of the water tank 42, and the spraying work is performed again. If the signal value is still greater than X1 and has not decreased significantly after the second spraying, it may be that the rust remover has been placed for too long, resulting in poor rust removal effect. Therefore, the device program sends an alarm signal to the staff, reminding the staff to replace the rust remover;

[0049] If the device program detects that the signal value of the pressure sensor has decreased significantly but is slightly greater than X1, at this time the rust remover is sprayed on the surface of the lock tongue, and the rust remover decomposes the rust on the surface of the lock tongue, causing the signal value of the pressure sensor to decrease significantly. At this time, the device program controls the second motor 22 and the fourth motor 24 to start, and the built-in pump of the water tank 42 starts, the fifth electric valve 432 is closed, and the sixth electric valve 433 is opened, so that the WD-40 rust remover in the rust remover storage chamber 423 is sprayed from the second cleaning nozzle 421 in the form of water mist onto the fire door lock through the built-in pump of the water tank 42. The device program sets the speed of the second motor 22 and the fourth motor 24 to V1, and the cleaning time to T1. The second cleaning brush 221 and the fourth cleaning brush 241 rotate at low speed and cooperate with the rust remover sprayed from the second cleaning nozzle 421 to remove the rust between the lock tongue and the lock body. When the cleaning time T1 is reached, the device program controls the second motor 22 and the fourth motor 24 to be closed, and the built-in pump of the water tank 42 and the sixth electric valve 433 are closed. Then the device program controls the air blower 41 to start, and sets the blowing time to T2. The air blower 41 compresses air and sprays it from the first cleaning nozzle 411 onto the fire door lock to blow away the impurities attached to the fire door lock after rust removal. After rust removal, the device program repeats the above lock tongue detection operation. If the device program detects that the signal value of the pressure sensor is less than X1, the device program does not operate,

[0050] If the device program detects that the signal value of the pressure sensor is still greater than X1, the above rust removal steps cannot restore the lock tongue to the normal pressure value range, so the device program sends an alarm signal to the staff, reminding the staff to replace the rusted fire door lock to ensure that the fire door lock can be used normally;

[0051] When the device program judges that the rust degree of the lock tongue of the door lock is heavy, the second cleaning brush 221 and the fourth cleaning brush 241 are rotated at a low speed, and the rust remover sprayed by the second cleaning nozzle 421 is used to remove the rust between the lock tongue and the lock body, and the time is Amin, so as to reduce the rust degree until the signal value of the pressure sensor detected by the device program is less than 2X1, the above-mentioned cleaning step X1 is repeated to clean the lock tongue, and if the rust removal of the lock tongue by the cleaning brush plate cannot significantly reduce the rust degree within Amin, the device program sends an alarm signal to the staff to remind the staff to replace the lock tongue.

[0052] Through the cooperation of the air compressor 31 and the three groups of telescopic air cylinders, the lock tongue detection can be performed on the door lock of the fireproof door installed at different heights, whether the lock tongue is rusted is judged by comparing the retracting degree of the lock tongue detected by the pressure sensor with the set value, and since the dust removal has been performed in the last step, the lock tongue will not retract slowly due to the mud and dust, manual detection by the staff is not needed, the working burden of the staff is reduced, the rust removal and lubrication are performed during the detection process, and the detection is performed again, so that the accuracy of the cleaning operation is ensured, the phenomenon that the cleaning is missed or not in place will not occur, the staff can be reminded to replace the door lock in time when the rust degree is too high, the service life of the door lock of the fireproof door is effectively improved, the rust removal and lubrication can be simply performed when the rust degree is small, the door lock does not need to be replaced, and the cost expenditure of the enterprise is reduced.

If the signal value of the pressure sensor is greater than X1 and less than 2X1, the device program determines that the rust degree of the bolt of the door lock is light. If the signal value of the pressure sensor is greater than 2X1, the device program determines that the rust degree of the bolt of the door lock is heavy.
