Summary of the invention
The invention provides a kind of anti-stealing manhole cover, be intended to solve the problem that in prior art, inspection well cover is easily stolen.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of anti-stealing manhole cover, comprises metallic support, wraps rubber shell, the warning device of the rectangle be connected on metallic support; Described warning device comprises the cylinder, box, the alarm circuit be arranged in box that are arranged on bottom rubber shell; Described box comprises upper cover and box body; On cover the cylindrical hole being provided with and matching with cylinder; Box body is provided with the cylinder groove matched with cylinder; Described cylinder groove communicates with the cavity of box body, alarm circuit comprise be connected in series with wire successively power supply, alarm, by cylinder control disconnect and close switch.
Further, described switch comprise switching the dwang of the cavity connectivity part of cylinder groove and box body, the torsion spring acted on dwang, be connected on dwang and the metal fork that can swing up and down in cylinder groove, be arranged on cylinder groove and box body cavity connectivity part and the wiring block be positioned at above metal fork; After inspection well cover is lost, can automatic alarm.
Further, described switch comprises the pole of the cavity connectivity part being fixed on cylinder groove and box body, the bimetallic lever of transferring on pole, the prap be connected in box body cavity, the length half section of described bimetallic lever is positioned at the cavity of box body, and short half section of bimetallic lever is positioned at cylinder groove; After inspection well cover is lost, can automatic alarm.
Compared with prior art advantage of the present invention is: in the present invention, inspection well cover adopts rubber shell and metallic support to form, and both ensure that quality, make again cost reduce, tenor is few, therefore generally can not be stolen; In addition alarm circuit can be reported to the police after inspection well cover is lost, and can remind passerby, decrease the generation of contingency; Alarm circuit is arranged in box can prevent artificial destruction.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 be bottom surface of the present invention upward time structural representation;
Fig. 2 is the structural representation of metallic support in the present invention;
Fig. 3 is the structural representation of alarm circuit in embodiment one;
Fig. 4 is the structural representation of alarm circuit in embodiment two;
Fig. 5 is the structural representation of inspection well cover and inspection shaft.
Detailed description of the invention
Embodiment one:
Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 5, a kind of anti-stealing manhole cover, comprise metallic support 1, wrap rubber shell 2, the warning device of the rectangle be connected on metallic support 1; Described warning device comprises the cylinder 3, box 4, the alarm circuit be arranged in box 4 that are arranged on bottom rubber shell 2, and described box 4 is connected on the ground for placing in the groove 11 of inspection well cover, and inspection shaft 10 is also positioned at groove 11; Described box 4 comprises upper cover 41 and box body 42; Upper cover 41 is provided with the cylindrical hole 6 matched with cylinder 3; Box body 42 is provided with the cylinder groove 5 matched with cylinder 3; Described cylinder groove 5 communicates with the cavity of box body 42, alarm circuit comprise be connected in series with wire successively power supply 7, alarm 8, by cylinder 3 control disconnect and close switch 9; Described switch 9 comprise switching cylinder groove 5 and the dwang 91 of the cavity connectivity part of box body 42, the torsion spring 92 acted on dwang 91, be connected on dwang 91 and the metal fork 93 that can swing up and down in cylinder groove 5, be arranged on cylinder groove 5 and box body 42 cavity connectivity part and the wiring block 94 be positioned at above metal fork 93; The cavity of described box body 42 communicates with inspection shaft 10, is convenient to discharge the water in groove.
When covering inspection well cover on inspection shaft, metal fork 93 presses down by cylinder 3, and metal fork 93 and wiring block 94 depart from, and switch 9 is in off-state.
When inspection well cover departs from inspection shaft, torsion spring 92 drives dwang 91 to rotate, and dwang 91 drives metal fork 93 upwards to swing, until metal fork 93 contacts with wiring block 94; Switch 9 closes, alarm circuit conducting, and alarm 8 (alarm 8 can be flash lamp, also can be jingle bell) is reported to the police.
Embodiment two:
Consult Fig. 4, be with the difference of embodiment one: described switch 9 comprises the pole 97 of the cavity connectivity part being fixed on cylinder groove 5 and box body 42, the bimetallic lever 95 of transferring on pole 97, the prap 96 be connected in box body 42 cavity, the length half section of described bimetallic lever 95 is positioned at the cavity of box body 42, and short half section of bimetallic lever 95 is positioned at cylinder groove 5; The separation of described length half section and short half section is the transit point of bimetallic lever 95.
When covering inspection well cover on inspection shaft, bimetallic lever 95 presses down by cylinder 3, and bimetallic lever 95 tilts, and departs from prap 96, and switch 9 is in off-state.
When inspection well cover departs from inspection shaft, the length half section whereabouts of bimetallic lever 95, bimetallic lever 95 contacts with prap 96; Switch 9 closes, and alarm circuit conducting, alarm 8 is reported to the police.
In the present invention, inspection well cover adopts rubber shell and metallic support to form, and both ensure that quality, make again cost reduce, tenor is few, therefore generally can not be stolen; In addition alarm circuit can be reported to the police after inspection well cover is lost, and can remind passerby, decrease the generation of contingency; Alarm circuit is arranged in box can prevent artificial destruction.
The foregoing is only specific embodiments of the invention, but technical characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
