Interior, the balloon 24 full of gas can rise out of pedestal 7, and swim in the top of well seat 2 by sebific duct II 23, play prompting work(
Energy.The color of wherein balloon 24 is chosen as yellow black phase secondary color, in day and night to the equal highly significant of light reflection effect.
Embodiment 4：Wherein single-chip microcomputer can be selected STC51 single-chip microcomputers, and other modules in controlling organization 8 can use commercially available
Model SVD-C19-500P5O9 voltage sensor can be selected in the common product that this function can be achieved, pressure sensor 5.
The course of work of the present invention is as follows：
1）During original state, controlling organization 8 is in holding state, the connecting bolt of well lid 1 and pedestal 7 to pressure sensor 5 at
In impaction state, the detected value of pressure sensor 5 is the numerical value more than 0, and when connecting bolt takes out, pressure sensor 5 is examined
Measured value can be changed into 0, and 0 value of reading will be sent to controlling organization 8 as trigger condition, the reception signal of controlling organization 8, initially enter
Running status, start impact mechanism 4 after preparing delay 1min, if bluetooth receiving module 26 is received from mobile phone in 1min
The releasing password that bluetooth is sent, then do not perform impact mechanism 4 and balloon alert mechanism 3, and device keeps holding state.If
Controlling organization 8 is not detected by the releasing password of Bluetooth of mobile phone transmission in 1min, then is identified as well lid pilferage, and controlled after 1min
The step motor control module 27 of mechanism 8 sends a signal to the counterattack stepper motor 12 of impact mechanism 4 by electric wire, strikes back stepping
90 ° are rotated counterclockwise after motor reception signal, is risen sebific duct I 18 and shower nozzle 15 by support bar 13, frizzen 17 compresses gas
The switch 19 of tank I 11, is inflated to sebific duct I 18, because overpressure gradually increases, when bearing pressure more than diaphragm seal 16
When, the interior liquid 14 pre-installed of pipe such as paints, capsicum water will spray because pressure is in 360 ° from shower nozzle 15, to stealer progress instead
Hit.After impact mechanism 4 realizes strike-back function, the step motor control module 27 of controlling organization 8 is sent a signal to by electric wire
The counterattack stepper motor 12 of impact mechanism 4,90 ° are rotated clockwise after striking back the reception signal of stepper motor 12, passes through support bar 13
Sebific duct I 18 and shower nozzle 15 are fallen, the trip switch 19 of frizzen 17, gas tank I 11 stops jet, and strike-back function terminates.
2）Due to without permission opening well lid, the action recognition is pilferage well lid by controlling organization 8, in strike-back function
After 4 terminate, after control system 8 enters delay 10min, start balloon alert mechanism 3.First, the stepper motor control of controlling organization 8
The balloon that molding block 27 sends a signal to balloon alert mechanism 3 by electric wire reminds stepper motor 21, and balloon reminds stepper motor
Rotate clockwise 90 ° after 21 reception signals, trigger the switch of the compression gas tank II 20 of connecting rod 22, gas tank II 20 passes through II 23 pairs of sebific duct
Balloon 24 is inflated, and due to buoyancy, balloon 24 rises, and is suspended in road surface due to the tractive force of sebific duct II 23
On, the balloon of yellow black alternate color is stronger to light reflection, so can all be carried out at daytime or night to the driver of dealing
Well lid lost reminding.
This manhole lid device individually pin can be worked independently, and also multiple well lids can be cooperated simultaneously.
Above in association with accompanying drawing to the present invention embodiment be explained in detail, but the present invention be not limited to it is above-mentioned
Embodiment, can also be before present inventive concept not be departed from those of ordinary skill in the art's possessed knowledge
Put that various changes can be made.
