Abstract
The invention relates to an inspection well theftproof device, which comprises a password input device and a locking device, wherein the password input device is provided with a signal transmitter; the locking device is provided with a signal receiver; the signal transmitter and the signal receiver are in radio connection; the locking device is arranged on an inspection well cover; after correct passwords are input in the password input device, the signal transmitter transmits a radio signal, the signal receiver receives the radio signal and the locking device is opened; and the locking device is automatically locked after the inspection well cover is covered for a period of time. The inspection well theftproof device is convenient in use, only people knowing the passwords can take away the inspection well cover so as to ensure that the inspection well cover is difficult to steal; the locking device is automatically locked after the inspection well cover is covered so as to prevent the inspection well cover form being stolen due to the oblivion of sanitation workers, thus protecting the safety of the inspection well cover and eliminating all opportunities for lawbreakers to steal the inspection well cover.
Description
Technical field
The present invention relates to a kind of anti-theft device, relate in particular to a kind of manhole cover anti-theft device.
Background technology
Inspection shaft covers in the city and is seen everywhere; the existence of inspection shaft lid greatly facilitates the sanitationman management and the mediation of sewer pipe over the ground; guaranteed the health of urban environment; but because anti-theft measure is not in place; the stolen situation of inspection shaft lid takes place through regular meeting; after the inspection shaft lid is stolen, not only can impact, also have influence on vehicular traffic and pedestrian's life security simultaneously environment on every side.Particularly under the situation that visibility is not high at night, the disappearance of inspection shaft lid is easy to cause all kinds of accidents, causes irretrievable loss.If there is a kind of inspection shaft cover tape that anti-theft measure is arranged, avoid opportunity to the unprincipled fellow, very big facility will be provided for people's life.
Summary of the invention
The purpose of this invention is to provide a kind of manhole cover anti-theft device, reduce the stolen possibility of inspection shaft lid, protect people's safety indirectly.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of manhole cover anti-theft device, comprise cipher input, locking device, wherein, on the described cipher input sender unit is installed, signal receiving device is installed on the locking device, sender unit and signal receiving device are by dedicated radio link, and locking device is installed in inspection shaft and covers; Behind the correct password of input on the cipher input, the sender unit transmitted radio signal, signal receiving device receives radio signal, and locking device is opened; Locking device automatically locked after inspection shaft covered a period of time.
Above-mentioned manhole cover anti-theft device, wherein, the time that locking device automatically locked after described inspection shaft covered is 5s.
Above-mentioned manhole cover anti-theft device, wherein, the figure place of the password of described cipher input is six.
Above-mentioned manhole cover anti-theft device, wherein, the quantity of described locking device has two.
Owing to adopted said method, it is good that the present invention has a theftproof performance than prior art, is difficult for being known that by the ruffian password has opportunity, advantage easy to use.
Description of drawings
Fig. 1 is the block diagram of manhole cover anti-theft device of the present invention;
Fig. 2 is the structural representation of manhole cover anti-theft device of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See also Fig. 1, a kind of manhole cover anti-theft device shown in Figure 2, wherein, comprise cipher input 1, locking device 4, it is characterized in that 1 is equipped with sender unit 2 on the described cipher input, and signal receiving device 3 is installed on the locking device 4, sender unit 2 passes through dedicated radio link with signal receiving device 3, and locking device 4 is installed in inspection shaft and covers; Behind the correct password of input on the cipher input 1, sender unit 2 transmitted radio signal, signal receiving device 3 receives radio signal, and locking device 4 is opened; Locking device 4 automatically locked after inspection shaft covered a period of time, and the time that locking device 4 automatically locked after inspection shaft covered is 5s, and the figure place of the password of cipher input 1 is six, and the quantity of locking device 4 has two.
The password of inspection shaft lid has only the sanitationman to know, the unprincipled fellow can't steal the inspection shaft lid easily.When the sanitationman opens the inspection shaft lid at needs, locking device 4 is opened behind the correct password of input on the cipher input 1, the inspection shaft lid can be taken off, and locks once more as need inspection shaft is covered, two locking devices 4 that inspection shaft covers installation behind the 5s automatically lock, and guarantee the safety of inspection shaft lid.
The present invention is easy to use, only knows that the people of password could take out the inspection shaft lid, makes the inspection shaft lid be difficult for stolen, and can automatically lock after covering, can not cause losing of inspection shaft lid because of forgeing of sanitationman, guarantee the safety of inspection shaft lid, not give lawless person's opportunity.
