Abstract
The invention relates to a cable device anti-theft anti-injury technology, in particular to an anti-theft anti-injury cable well lid which solves the technical problem that facilities in a cable well are easy to steal, and pedestrians may be injured easily after a well lid is open at present. The anti-theft anti-injury cable well lid comprises a double-layer well lid which comprises an annular base located under the well lid and a top lid arranged above the base. An opening is formed in the annular edge of the base, a travel switch is arranged in the opening, and the travel switch is connected with a signal transmitter in series through a loop. The signal output end of the signal transmitter is connected with a data transmission unit (DTU) through a cable. The signal output end of the DTU is connected with a receiver through an optical fiber, and the travel switch is in opening-closing fit with the top lid. The anti-theft anti-injury cable well lid can effectively achieve real-time monitoring of the cable well lid and is simple in structure, low in production cost and very convenient to install.
Description
Technical field
The present invention relates to the antitheft anti-error technology of cable machinery, be specially a kind of antitheft anti-error cable well lid.
Background technology
Nowadays in many cities, original overhead wire, through engineering construction transformation, all changes into into ground cable, has increased a lot of cable inspection wells simultaneously.Some communication cables also enter ground by original making somebody a mere figurehead by cable passage.
But in actual motion, find that cable inspection well exists some potential safety hazards.1, some communication cable management units are in the time privately entering cable inspection well to its optical cable construction, owing to not understanding electric power safety relevant knowledge, and the strick precaution of not taking care.2, the well lid of cable inspection well is easy to open, and after opening, owing to lacking due supervision, for limiting, some vandalisms strick precaution dynamics are limited.For ensureing cable trench well lid safety, avoid opening and causing the accident that pedestrian falls to occur because of well lid, need to strengthen management and the monitoring to cable inspection well, to grasp in real time the situation of cable shaft, in time field condition is judged.But lack at present a kind of effectively device and can be good at realizing above-mentioned functions.
Summary of the invention
The present invention be solve in current cable shaft facility easily stolen and well lid open the rear technical problem that easily causes pedestrian to accidentally injure, a kind of antitheft anti-error cable well lid is provided.
The present invention adopts following technical scheme to realize: a kind of antitheft anti-error cable well lid, comprise a Double-layer drain cover, and described Double-layer drain cover comprises the top cover that is positioned at the base in the form of a ring of below and is arranged on base top; The ring-shaped edge of base is provided with in an opening and opening and is provided with a travel switch, and travel switch is serially connected with a signal transmission device by loop; The signal output part of signal transmission device is connected with a transfer of data cells D TU by cable; The signal output part of DTU is connected with receiver by optical fiber; Described travel switch and top cover open and close and are equipped with.
Change well lid into Double-layer drain cover, above base border, add that a travel switch and signal transmission device are to monitor the operation trend of well lid, and monitor message is uploaded on the receiver of electric company's dispatch center by the communication device on cable trench (DTU), the just trend of monitoring cable well lid in real time of the staff who is positioned at like this Surveillance center, guarantees that cable well lid is in normal position; Base is fixed on the edge of cable shaft, and top cover and travel switch cooperatively interact and realize the open and close of signal transmission device; In the time that well lid is separated from base, travel switch closure, its loop conducting, signal transmission device is transferred to receiver by DTU by corresponding signal by corresponding signal (audio frequency or vision signal or switching value signal); After well lid is built, travel switch just disconnects, and signal transmission device just quits work.When cable well lid (is opened or moves) not on normal position, travel switch will be sent to receiver by corresponding signal by connection signal transmitter, receiver can receive switching value signal or audio or video signal, staff just can know the situation of cable well lid, is convenient to notify in time relevant departments to take measures to prevent to open the stolen situation of facility in accident that pedestrian falls down or cable shaft is occurred because of well lid.
Further, described signal transmission device is video signal transmission device; Base inward flange is also equipped with the video probe being connected with video signal transmission device input.
Adopt video signal transmission device to monitor, monitor staff can clearerly observe the situation of cable well lid, guarantees safety.
The present invention can effectively realize the real-time monitoring to cable well lid, effectively avoided well lid open rear easily cause pedestrian to accidentally injure and down-hole facility is stolen or destroy problem; Corresponding communication device is all located in well lid or in cable trench, can not increase on the ground any structure, can not pass through and cause interference ground.The present invention is simple in structure, and cost of production is low, installs also very convenient.
