Abstract

The utility model provides an antitheft device for cable trench and manhole cover plates, which comprises a plurality of cover plates. Manual antitheft inserting pins are mounted on one part of the cover plates, electric built-in locks which are remotely controlled are mounted on the other part of the cover plates, the manual antitheft inserting pins and the electric built-in locks are configured and staggered in a certain proportion, and the electric built-in locks are connected with a leakage switch mounted in a power distribution room through cables. Antitheft of cable trenches and manholes is realized by means of the manual antitheft inserting pins and the electric built-in locks, and on and off of the electric built-in locks are controlled by the leakage switch mounted in the nearest power distribution room, so that antitheft protection of the cables or the cover plates in the cable trenches and manholes is realized, theft of metal cables or cover plates by lawbreakers can be effectively prevented, and the antitheft device for the cable trench and manhole cover plates is convenient in mounting and operation and worthy of popularization.

Description

A kind of cable trough, the anti-device of stealing of well lid plate

Technical field

The utility model relates to municipal facilities, the anti-pilferage device of especially a kind of cable trough, well lid plate.

Background technology

High-tension cable is laid in the cable trough usually or buries in underground (the inspection active well that keeps at a certain distance away); The unprincipled fellow opens the situation that cable channel cover plate, cable work well cover plate steal cable or steal the cable cover plate and happens occasionally; Cause the generation of the accident of large-area power-cuts or loss of life or personal injury, cause heavy losses to society.

The utility model content

Stolen the problem of high pressure cable or cover plate by private opening for solving above-described cable trough, cable shaft cover plate; The anti-pilferage device of the cable trough that the utility model proposed, well lid plate installs Theftproof bolt additional in the cover plate bottom surface, and has realized the anti-pilferage function to cable trough, well lid plate at the electronic built-in lock of switchgear house inner control.

The technical scheme that the utility model is taked is:

A kind of cable trough, the anti-device of stealing of well lid plate include a plurality of cover plates, manual Theftproof bolt is installed on the splitted cover board of center, and the electronic built-in lock of Long-distance Control is installed on remaining cover plate, and both dispose and staggered arranging in certain proportion; Correspondingly cable trough, well both sides body of wall are provided with the jack of the latch of corresponding Theftproof bolt and electronic built-in lock, and said latch inserts and realizes the locking anti-theft feature in the said jack; Said electronic built-in lock uses the 220v power supply, causes power distribution room nearby through burying in underground cable, and be installed in power distribution room in and the leakage switch of controlling its action be connected.

As a kind of improvement of above technical scheme, the said cover plate that Theftproof bolt is installed with the ratio setting of the cover plate of electronic built-in lock in 10:1 is installed.

The beneficial effect of the utility model is:

Theftproof bolt that the utility model utilization is manual and electronic built-in lock are realized the anti-theft feature to cable trough, well; And realize control to the open and close of electronic built-in lock through the leakage switch that is installed in power distribution room nearby; And then realize cable or the anti-theft protection of cover plate in cable trough, the well; Can not only prevent effectively that the lawless person from stealing wire rope or cover plate, and convenient installation and operation, be worthy to be popularized.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the end view that the utility model has the cover plate of electronic built-in lock;

Fig. 2 is the end view that the utility model has the cover plate of Theftproof bolt;

Fig. 3 is the sketch map of the utility model.

Embodiment

Like Fig. 1, shown in 2 and 3; Cable trough disclosed in the utility model, well lid plate anti-theft device include a plurality of cover plates 1; Add Theftproof bolt 2 on the center splitted cover board 1, and the electronic built-in lock 3 of Long-distance Control is installed on other a part of cover plate 1, both are provided with in certain proportion; Such as 10:1, promptly whenever a cover plate 1 that has electronic built-in lock 3 is set at a distance from 10 cover plates 1 that have Theftproof bolt 2.Wherein each cover plate 1 that has a Theftproof bolt 2 all has two Theftproof bolts 2 that are installed in cover plate 1 both sides; Correspondingly cable trough both sides body of wall is provided with corresponding jack 4, and the latch 21 of Theftproof bolt 2 inserts and realizes the locking anti-theft feature in the jack 4.The electronic anti-theft built-in lock 3 that has the cover plate 1 of electronic anti-theft built-in lock 3 is installed in its central authorities, and the latch 31 of electronic built-in lock 3 can stretch out towards cover plate 1 both sides or withdraw under the driving of electro-motor; Correspondingly, cable trough well both sides are provided with the jack 4 of the latch 31 of corresponding electronic built-in lock 3 equally.Electronic built-in lock 3 uses the 220v power supply, through 1mm with the 40PE pipe box ²Copper core buries in underground 80cm place, causes power distribution room nearby, and at power distribution room 3 16A/1P leakage switch (not showing in the accompanying drawings) long distance is installed and controls electronic built-in lock switch 3.

During use, the electronic built-in lock 3 that is disposed through leakage switch control cable ditch in the power distribution room or cable shaft cover plate 1.In switching on, the latch 31 of electronic built-in lock 3 stretches out in the jack 4 that inserts cable trough well sidewall and pins cover plates, and cable channel cover plate 1 is provided with the electronic built-in lock of a cover, the manual Theftproof bolt 2 that all the other uses are common at a distance from ten in this embodiment; In the outage, after untiing electronic built-in lock 3 and opening the cover plate 1 that is equiped with electronic built-in lock 3, remove the cover plate of installing Theftproof bolt 2 more successively and can the cover plate 1 of cable trough or cable shaft all be opened.On the contrary; After construction is accomplished; As long as earlier all cover plates 1 that are equiped with Theftproof bolt 2 being reinstalled the cover plate 1 that will be equiped with electronic built-in lock 3 behind cable trough or the cable shaft more successively reinstalls; Through the leakage switch of power distribution room electronic built-in lock 3 is locked then, be not used in the space of removing Theftproof bolt 2 this moment, promptly realized anti-theft feature.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection range, so long as realize that with essentially identical means the purpose of the utility model all should belong to the protection range of the utility model.
