Background technology
Along with the continuous development of social modernization's degree, the people's living standard improves day by day, and every high-tech makes rapid progress especially, and each side shows its own prowess.Citizen but have a slice shade to can't get rid of all the time when enjoying convenient and economical that high-tech product brings, and that is exactly city " black hole "---stolen the inspection shaft of well lid, the frightened and influence that stays to people.It is threatening the civic person and property safety ubiquitously, though municipal relevant department to this suitable attention, and drops into a lot of funds and fills up this " black hole ", produces little effect.Existing inspection shaft lid, a part is made for cement, and the weight that this inspection shaft lid is difficult to bear vehicle often has the damaged phenomenon of stopping up sewer of cement lid.All the other major parts are made for cast iron, and anti-theft feature is poor, often have the stolen thing of inspection shaft lid to take place, though designed a lot of antitheft inspection shafts lids, generally be to cost an arm and a leg, transform complexity.The disclosed inspection shaft lid of China's ZL200420020997.9 patent " manhole cover anti-theft device ", increased by a lock body with magnetic marble, really has good anti-theft effect, but the designer has but ignored the problem that magnetic marble can adsorb iron material, and necessary dust guard is not set, can cause like this owing to the dust on the magnetic marble too much cause stuck, well lid can't be opened.The disclosed inspection shaft lid of China's ZL200420025803.4 patent " anti-stealing manhole cover and special opening device thereof ", be provided with a gear and with the dead man of gears engaged, drive the motion of dead man by the transmission of gear, can make dead man be stuck in the locking of finishing well lid under the manhole cover base with this, but its opening device is too simple, is easy to copy.Also there are the problems referred to above in the disclosed inspection shaft lid of China ZL01249818.1 patent " dual fail-safe inspection shaft lid and special opening device thereof ".
Summary of the invention
First technical problem to be solved in the utility model provides a kind of inspection shaft lid with strong anti-theft feature, and another technical problem that will solve provides a kind of special opening device of opening this inspection shaft lid.
The utility model is realized in the following manner to above-mentioned technical problem:
A kind of anti-stealing manhole cover, described anti-stealing manhole cover comprises a lid, at the lid bottom centre position one antitheft locking device is installed, locking device bottom centre place is a rotating disk that can rotate along the center, rotating disk can be connected with lid by a bearing arrangement, and rotating disk can be rotated freely along the center under external force; In rotating disk, be inlaid with some silicon steel sheets, accept the magnetic strength of opening device when being used to open; Around the periphery of rotating disk some lockings being installed radially fastens.
Anti-stealing manhole cover described in the utility model, between fastening, rotating disk and each locking is provided with connecting rod, rotating disk is connected with connecting rod by linkage, fasten by linkage and a locking equally at the other end of connecting rod and to link to each other, locking is fastened and is fastened seat by a locking and is fixed on the lid, locking is fastened can fasten a upper edge disk diameter direction in locking move forward and backward under the effect of connecting rod power.When the inspection shaft lid was lock-out state, locking was fastened and is stretched out from lid, exceeds the lid periphery, and is stuck in the lower edge of manhole cover base; But when inspection shaft lid opening, withdrawal is fastened in locking, in be received in the lid periphery.
Antitheft locking device described in the utility model, the inspection shaft that can be attached to existing different shape very easily under the situation of the structure of not destroying existing inspection shaft lid and mechanical property covers, make existing inspection shaft lid have good anti-theft feature, and install additional simply, expense is cheap.
Anti-stealing manhole cover described in the utility model is also supporting have a special opening device, special opening device comprise a rotation actuating mechanism, for the rotation actuating mechanism provide power storage battery, a charger for the storage battery charging, connect storage battery and the transformer, operating board and the switch block that rotate actuating mechanism.Described rotation actuating mechanism comprise a bakelite plate and be installed on the bakelite plate with rotating disk on the coil of the supporting band silicon steel sheet of silicon steel sheet, added voltage is 2000V～3000V on the coil, is provided by transformer by storage battery.
Described special opening device, only needing during use that opening device is placed on inspection shaft covers, connect power supply, because the coil of band silicon steel sheet produces powerful magnetic field under 2000V～3000V voltage, make to be installed on the rotating disk and be subjected to powerful magnetic field force effect with the supporting silicon steel sheet of silicon steel sheet coil, when the turn of rotation actuating mechanism clockwise direction, the also rotation thereupon of rotating disk of silicon steel sheet is installed under the effect of magnetic field force, and the transmission by connecting rod makes the lock plunger withdrawal, can the inspection shaft lid be opened by normal mode.When needs locking inspection shaft lid, equally according to the method described above, be rotated counterclockwise and rotarily open device, locking is fastened stretch out, be inserted under the manhole cover base and get final product.
Described special opening device, charge to storage battery by charger by the 220V alternating current, also can directly power by the storage battery on the automobile, and can open more than 500 times after the charging, easy to use, and this opening device is difficult imitated, and imitated this device will be lost more than gain if the thief is in order to steal the inspection shaft lid.
