As the optimized arrangement mode, the fire hydrant of the scheme can be arranged under the street lamp, so that the photosensitive detection component 31 can be used at night, and the phenomenon that the anti-theft effect is weakened at night is avoided.

As a modified specific embodiment, the latch cover 2 includes a cover body 21 and a light shielding sheet 22, and the light shielding sheet 22 is detachably connected to the cover body 21.

Divide into lens 22 and lid 21 with bolt lid 2, can simplify the production degree of difficulty, through the later stage combination, the production degree of difficulty of earlier stage can reduce.

In addition, the light-shielding sheet 22 is made of plastic or glass material and has a light-shielding coating. The plastic or glass materials mentioned in the above are all destructible materials, and in such a matching manner, the locking can be contacted by smashing and quickly destroying the light shielding sheet 22 in an emergency situation, for example, fire emergency rescue is avoided, unlocking delay of rescue time is avoided, the generated alarm can also remind surrounding people to be far away, and the situation that the people leave the server can be removed after the situation.

In a modified embodiment, the control circuit 32 is further connected with a locking assembly 4, and the locking assembly 4 is arranged on the fire hydrant top cover 1 and used for locking the hydrant cover 2.

In order to further lock the latch bolt 42, the latch cover 2 can be locked by arranging the locking assembly 4, when the latch cover 2 is connected to the fire hydrant top cover 1 through threads and the latch cover 2 is rotated to a proper position, the locking assembly 4 locks the latch cover 2, and the locking assembly 4 limits the reverse rotation of the latch cover 2, so that the latch cover 2 is prevented from being opened. Wherein control circuit 32 can cooperate RFID identification technology, bluetooth or networking wireless communication technology in addition to carry out identification, and control circuit 32 unlocks the identity that has the authority, and control circuit 32 control locking Assembly 4 gets into the unblock mode this moment, and the user can reverse rotating bolt cover 2 this moment, and after pulling down bolt cover 2, the user can be through like opening the fire hydrant in this scheme. Through above-mentioned scheme, can lock the top cap of fire hydrant with 2 cooperation locking Assembly 4 of bolt lid, cooperation photosensitive detection subassembly 31 further improves the theftproof effect, avoids the phenomenon appearance of the interior water supply of abnormal use fire hydrant. The method is beneficial to maintaining social image, avoids influencing the image by stealing the water source of the fire hydrant, and even can avoid the condition that the fire hydrant is damaged in the stealing process, so that water can not be normally supplied when the fire hydrant is used emergently.

Specifically, the locking assembly 4 includes a motor 41, a latch 42 and a resilient linkage, the motor 41 is electrically connected to the control circuit 32; the motor 41 is linked with the latch 42 through an elastic linkage, the motor 41 drives the latch 42 to extend and retract so as to lock or unlock the latch cover 2, and when the motor 41 drives the latch 42 to extend, the latch 42 is ejected out by the elasticity of the elastic linkage so as to lock the latch 42.

When the control circuit 32 locks or unlocks the locking assembly 4, the motor 41 is controlled to rotate to control the latch 42 to extend or retract, the motor 41 drives the gear to rotate through the matching of the rack and the gear, the gear and the rack are meshed to drive the rack to transmit, the rack is fixed on the latch 42, and the linkage of the latch 42 can be completed.

As an embodiment, the elastic linkage member may be a spring plate, the spring plate is fixed on the rotating shaft 46 of the motor 41, the motor 41 rotates to drive the spring plate to rotate, at this time, the spring plate pushes the lock bolt 42 to extend, because the spring plate has certain elasticity, at this time, the lock bolt 42 has certain telescopic capability, when the bolt cover 2 is screwed into the fire hydrant top cover 1 and the lock bolt 42 is not yet aligned with the hole on the bolt cover 2, the lock bolt 42 is pressed to retract, when the bolt cover 2 continues to rotate, and the hole on the bolt cover 2 is aligned with the lock bolt 42, at this time, the lock bolt 42 is ejected out of the hole embedded in the bolt cover 2 under the elastic force of the spring plate. Therefore, the locking effect can be improved, the situation that the control circuit 32 needs to detect whether the bolt cover 2 rotates in place and then controls the bolt 42 to extend out for locking is avoided, the control of the control circuit 32 is simplified, and the locking action is simpler and more effective.

In a preferred embodiment, the elastic linkage member includes a spring 43 and a support block 44, the support block 44 is assembled with the latch 42 to drive the latch 42 to move, the spring 43 is linked with the motor 41 and also abutted against the support block 44, the motor 41 drives the spring 43 to push the support block 44 to drive the latch 42 to lock or unlock the latch cover 2.

More specifically, the locking assembly 4 further includes a rotating shaft 46 linked with the motor 41, a driving block 45 is disposed on the rotating shaft 46, the spring 43 is sleeved on the rotating shaft 46, the driving block 45 is embedded between pitches of the spring 43, the supporting block 44 is slidably connected to the rotating shaft 46, and the rotating shaft 46 drives the spring 43 to compress or restore through the driving block 45.
