And the well lid control system which normally works can lock all internal vertical normally open type ring locks when detecting that the cover of the operation opening is illegally opened, and push alarm information to the server and send out audible and visual alarm to prevent an illegal cover opener from further opening the well lid lock and wait for the arrival of maintenance personnel. After the well lid control system fails, all internal vertical ring locks are in a normally open state, and the transverse normally closed ring locks are in a normally closed state, so that maintenance personnel can also use a wireless power supply to open the operation port cover for manual removal of lock bolts for maintenance. When the well lid control system is normal, the well lid control system refuses to accept unlocking in a wireless power unit mode and unlocking in a mode of damaging the cover of the operation opening. The specific advantages are as follows:
1. when the well lid control system is normal, the wireless power supply is refused to unlock, and when the operation opening cover is detected to be broken by mechanical force, the vertical normally open ring lock in the well lid control system can be locked, so that illegal opening personnel can be prevented from further opening the well lid; under the condition of the failure of the well lid control system, the operation opening cover is supported to be opened in a wireless power supply mode, and then the well lid is opened in a mode of manually taking down a lock bolt sleeved on an internal normally open vertical ring lock; under the conditions that the well lid control system fails and the unlocking mode of the wireless power supply fails, the mechanical force mode is allowed to break the operation opening cover to manually take down the lock bolt, and the well lid is opened, so that the unlocking maintenance cost of the well lid lock caused by the well lid control system failure is reduced to the minimum;
2. the well lid lock locking mode of the internal vertical normally open ring lock sleeve padlock is adopted, so that the static power consumption of the system is greatly reduced, and meanwhile, after the well lid control system fails, the internal vertical ring lock of the sleeve padlock is in a normally open state, so that maintenance personnel can conveniently remove the lock bolt manually, and the well lid is opened;
3. the transverse normally-closed ring lock of the operation port cover ensures that the manhole cover control system is in a locking state when in fault, and prevents illegal personnel from opening the operation port cover and opening the manhole cover;
4. when the well lid control system works normally, on one hand, unlocking in an unlocking mode of the wireless power supply device is refused through the control circuit, on the other hand, whether illegal opening actions exist or not is detected through a position sensor of the operation opening cover, if so, the vertical normally open type ring lock inside the well lid control system is immediately locked, and alarm information is pushed to the server or an audible and visual alarm is sent;
5. the notch of the internal vertical normally open ring lock on the back of the well cover is close to the 60-degree range of the connecting point on the back of the well cover, so that when the lock ring of the lock bolt is sleeved on the internal vertical normally open ring lock, the lock bolt is prevented from sliding off due to external vibration.
