The invention discloses an intelligent antitheft 
municipal well lid comprising a well lid body, a two-dimensional code, a 
light energy power generation module, a charging management module, an accumulator, a 
GPS positioning module, an electronic lock, an 
alarm device, a back-stage 
management system and the like. The whole 
system is integrally mounted in the well lid; an operation power source is provided for the 
system through the 
light energy power generation module, the charging management module and the accumulator; the electronic lock is opened and closed by scanning the two-dimensional code; the 
alarm device is used for monitoring the 
water level and the air quality in a well, when the 
water level is excessively high or the air quality is poor, the 
alarm device gives an alarm automatically and sends information to the back-stage 
management system automatically, and a passerby can also provide the corresponding information for the back-stage 
management system by scanning the two-dimensional code after hearing the alarm; and the intelligent antitheft 
municipal well lid integrates multiple functions and is convenient and rapid to install and use, the dangerous situation inside the 
municipal well can be automatically monitored, and the situation that the well lid is stolen is reduced greatly through a two-dimensional code unlocking mode.
