Abstract
The utility model relates to inner well cover devices for installing channel wells such as underground channels, pipe networks, civil air defense channels and the like, and in particular relates to a mechanical anti-theft inner well cover. An operating opening is arranged at an upper opening hole of the inner well cover, a rotating piece is arranged below the operating opening, the rotating piece is arranged at the bottom surface of the inner well cover by bolts, a lockset comprises a lock bolt and a lock bolt seat, the lock bolt seat is arranged in the middle position of the bottom surface of the inner well cover, the lock bolt is arranged on the lock bolt seat in a penetrating and inserting way by a lock core, the lock core is opened by a special key, and is in linkage with the lock bolt, and when the length of the lock bolt is greater than the diameter of a well opening, two ends of the lock bolt are buckled by a lock catch, so that a multiple-point lock catch structure can be realized. The inner well cover is small in volume and simple in structure; the bottom surface of the well cover is melted into a whole body, so that the damage and the corrosion caused by external force can be well prevented, and the opening and the closing of the well cover can be easily realized from the outer side by using the special key; the lock catch has stronger damage resistance, and the well cover can be deadlocked by the multiple-point lock catch mode, so that the damage from the outer side can be effectively prevented and a well anti-theft effect is realized.
Description
Technical field
The utility model relates to the interior well lid equipment of passage wells such as underground passage, pipe network, people's air defense are installed, well lid in particularly a kind of mechanical type antitheft.
Background technology
For passage wells such as underground passage, pipe network, people's air defense are installed on positions such as ground or street; Need well lid be set at the well head place of passage well; Mainly be that staff's access way well carries out work for ease, also will guarantee that the road surface is current and avoid other passerbys to fall into the passage well simultaneously.
Traditional well lid is divided into inside and outside well lid, and outer well lid carries outside road surface pressure, and interior well lid only is used to prevent fall into higher level's underground equipment or pipeline in the well after the outer well lid breakage, but this type of well lid does not all contain anti-theft feature, and stolen phenomenon is serious, and potential safety hazard is serious.
Along with the frequent generation of stolen phenomenon, just designed Manhole cover with lock afterwards, comprising: three kinds of inner locking type, outer locking-type and electric locks, preceding two kinds all is the mode that the mechanical lock that adopts is realized locked well lid, the third adopts electric lock to realize the unlatching of well lid.Wherein: outer locking-type, lockset are positioned at the well lid outside, be prone to open, but anti-theft capability are poor, is prone to be destroyed; Inner locking type, lockset are positioned at the well lid inboard, and anti-theft capability is stronger, but can only operate internally during opening and closing, complicated operation, and it is extremely inconvenient need open the time to meet emergency especially, and is not suitable for the little situation in space, down-hole and uses; Electric lock is realized switch through the drive tapered end of motor, and anti-theft capability is stronger; But need the installation site that power supply and conditions such as communication line and protection against the tide must be provided, very big to the environment limitation, and owing to adopt electric elements and power circuit etc.; Cost is high, is not suitable for using in batches.
The utility model content
The utility model is to address the above problem well lid in a kind of new mechanical type antitheft is provided; The requirement that not only intensity can traditional well lid; Can prevent effectively that outer interior well lid from falling into the equipment that injures in the well or pipeline because of the external force fragmentation, adopts the mechanical system transmission, dispense with outer connecting power or holding wire etc.; Little to the environment dependence, the well head that is fit under the various environment uses.
The technical scheme of the utility model is following:
Well lid in the mechanical type antitheft covers the well head of closed channel well on the manhole cover base on ground, it is characterized in that: in said on the well lid perforate be provided with gathering hole, interior well lid bottom surface is provided with lockset; Be provided with a rotatable lamella below the said gathering hole, well lid bottom surface in rotatable lamella is installed on through bolt, rotatable lamella can be that axle rotates with the bolt; Said lockset comprises locking bolt and the locking bolt seat that is used to install locking bolt; The centre position of well lid bottom surface in the locking bolt seat is arranged at; Locking bolt is interspersed to be installed on the locking bolt seat; Connect through lock core between locking bolt and the locking bolt seat, lock core is opened through the lockhole that key inserts on the locking bolt seat, and lock core is opened the interlock locking bolt and moved; The two ends of said locking bolt all are set with one and are used for the snap close that fastens with locking bolt, and the length of locking bolt is greater than the diameter of well head.
The bottom surface of well lid in said snap close is fixed in, on the manhole cover base that well lid was corresponding in perhaps snap close was fixed in, the distance that the longitudinal aperture of snap close moves up and down more than or equal to locking bolt, the horizontal aperture of snap close is more than or equal to the diameter of locking bolt.
The galvanizing steel that said snap close employing diameter is Φ 16m/m is processed, and stronger anti-destructive is arranged.
When installing and using the utility model on the manhole cover base, if need opening in the interior well lid entering passage wells such as pipe network below ground, the staff works, only need the push-jump rotatable lamella of staff; Expose gathering hole; Hand is put in interior well lid lower end, private key is inserted lockhole open lock core, locking bolt then links; Locking bolt breaks away from snap close, opens interior well lid; In like manner, the staff builds interior well lid after hours, and well lid lower end in hand puts in through gathering hole is inserted lockhole with private key and opened lock core, the interlock locking bolt, and locking bolt and snap close fasten, and then can lock interior well lid.
The beneficial effect of the utility model is following:
The lockset of the utility model adopts the special-purpose theft-proof lock bolt, and volume is little, and is simple in structure, and its bottom surface that is installed on well lid is fused into an integral body, can well prevent outside destroy and anticorrosive, and is easy to utilize private key to realize the opening and closing of well lid from the outside; Snap close has stronger anti-destructive is arranged; Adopt the mode of multiple spot snap close to realize the locked of well lid; Can effectively prevent the destruction from the outside, play good anti-theft effect, this well lid is because problems such as the cost when selection and design aspect have all been considered extensive use and installation facilities in addition; Therefore need not when installing and using that existing well head is done too much adjustment can install and use, and the batch that is fit to Urban Buried Pipeline Network passage well head is installed and used.
