As shown in fig. 1 and 2, when the blast furnace stops operating, the operator turns off the button for controlling the power switch W and does not perform any operation. Therefore, two normally open contacts in the control power switch W are opened, so that the anode of a 12V power supply output by a pin 3 of the switch power supply A1 does not enter the anode power supply input end of the relay J, the relay J is not electrified to pull the control power supply input end and the normally closed contact end to be closed, and the control power supply input end and the normally open contact end are opened; because the control power input end of the relay J is connected with the pin 3 of the switch power supply A1, the normally closed contact end of the relay J, the pin 4 of the switch power supply A1 and the

pins

1 and 2 of the time control switch A2 are connected, the time control switch A2 can be electrified to work at the moment, under the action of the internal circuit of the time control switch A2 and the time of the power output of the

3 and 4 set by technicians, the

3 and 4 of the time control switch A2 can output power for 10 seconds and enter the two ends of the power input end of the submersible pump M through one-way conduction of the diodes VD1 and VD2, the submersible pump M is electrified to work, meanwhile, the power output for 10 seconds of the

3 and 4 of the time control switch A2 can also enter the two ends of the DC power input end of the electromagnetic valve, and then the internal valve core of the electromagnetic valve DC is electrified to work, so that the water pumped out of the submersible pump M can flow out of the water inlet pipe 8 and, The connecting pipe 41 pumps out, water with pressure is sprayed at the front outer end of the front glass plate 712 (diameter is 4 cm) from the lower part of the other end of the connecting pipe 41, dust and the like adhered to the front outer part of the foremost glass plate of the barrel 71 during the operation of the blast furnace at each time can be automatically flushed in 10 seconds (due to the fact that the water with pressure can be scattered when being sprayed out from the lower end of the connecting pipe 41, water can effectively clean and flush the front outer part of the glass plate 712), a better cleaning effect can be achieved, and the definition of video shooting by the camera is ensured as much as possible. In this is novel, the technician can also open the component lid and adjust time of time switch A2 output power, sets for the different output power time of time switch A2 to outside dust etc. carry out the automation of different times before the foremost glass board of barrel 71 and erode, reach good cleaning performance. Through the aforesaid, this is novel just can once wash the glass board 712 of camera front end automatically after the blast furnace is closed at every turn, guarantees that it is in clean state, for the next use of blast furnace, the clear image of camera shooting is ready (the blast furnace uses once, and the actual adhesion is few at the dust of glass board 712 front end, and it can satisfy the needs once washing to use up at every turn).

As shown in fig. 1 and 2, in the present invention, the submersible pump M can continuously pump clean water into the space between the two

glass plates

712 and 713 at the front end of the camera 1 to cool the camera 1 and the

glass plates

712 and 713, so as to prevent the camera 1 and the glass plates 712 from being damaged by high temperature; under the effect of control circuit 6 and control switch 10 etc, after the blast furnace shut down every day, can open electromagnetic water valve 4 in a period of time, and then the clear water that immersible pump 73 was taken out is spout from the connecting pipe 41 other end, wash away automatically the preceding outside of barrel foremost glass board 712, can effectively wash away the dust of adhesion outside before barrel foremost glass board 712 automatically like this, and wash the time as required adjustable, this novel convenient to use, do not need the artificial operation of managers, and can reach better clean effect, the definition of video is shot to the camera has been guaranteed as far as possible.
