2.During well lid 1 is started, it is inserted into and is opened in through hole 3 using crowbar 12 so that inserted the bent portion of the front end of crowbar 12
Enter into catching groove 4 to catch on catching groove 4, then dropping well lid 1 makes it be moved to side, and in moving process, the bottom surface of well lid 1 is to pass through rolling
Pearl 2 rotates movement, and caused is rolling friction, and under square one, frictional force is smaller for rolling friction, required for mobile well lid
Power it is smaller.It is moved easily.
Learn whether well lid covers firm for convenience, and whether well lid is lost due to reasons such as artificial or floods
Lose, there is provided multiple pressure sensors 6, controller 7 and alarm 8；The junction of well lid 1 and well seat 5 sets pressure sensor
6, the output end of pressure sensor 6 is connected with the input of controller 7, and the output end of controller 7 connects with the input of alarm 8
Connect；Pressure sensor 6 detects well lid 1 and produces pressure, transmits the pressure for transmitting pressure sensor 6 to controller 7, controller 7
Value is compared with default pressure minimum, and when pressure is less than default pressure minimum, controller 7 controls alarm 8
Alarm, the well lid 1 of the upper end of well seat 5 is reminded not cover or without well lid.The wherein model of pressure sensor 6：QLW-15；Control
