Summary of the invention

The object of the invention is to the drawback for prior art, provide a kind of well lid with the protection of opening and alarm function, the potential safety hazard causing to get rid of manhole cover loss.

Problem of the present invention realizes with following technical proposals:

A kind of well lid with the protection of opening and alarm function, formation comprises walling crib, well lid and safety net, described walling crib is fixed on well head, on the anchor ring of its inner side, is provided with the annular convex rib coaxial with it, is also provided with a plurality of along its circumferential uniform safety net link in the lower inside of walling crib; The outer rim of described well lid is pressed on the convex tendon of walling crib inner side, and one side and walling crib are hinged; Described safety net is rounded, and its periphery is provided with the hook that the safety net link in a plurality of and walling crib matches.

The above-mentioned well lid with the protection of opening and alarm function, also comprises alarm lamp and lamp stand in formation, the upper end of described lamp stand is alarm lamp fixedly, and top, lower end is hinged by the convex tendon of horizontal rotating shaft and walling crib inner side, on described horizontal rotating shaft, is provided with torsionspring; A side in lamp stand lower end near walling crib center is also provided with lamp stand limiting plate, and described lamp stand limiting plate is fixedly connected with walling crib inwall.

The above-mentioned well lid with the protection of opening and alarm function, also comprises noctilucence float in formation, described noctilucence float is clipped between well lid and safety net and is connected with walling crib or safety net by rope.

The above-mentioned well lid with the protection of opening and alarm function, the inner side of described well lid scribbles Luminous warning paint.

The above-mentioned well lid with the protection of opening and alarm function, the outer rim of described safety net is provided with screen frame, and described hook is connected with safety net by screen frame.

The above-mentioned well lid with the protection of opening and alarm function, the switch of described alarm lamp adopts limit switch, and described limit switch is fixed on the lower end of lamp stand, and its trigger head is corresponding with lamp stand limiting plate.

The present invention has set up safety net and multiple well lid opening warning device on the basis of traditional well lid, no matter well lid is because of what reason unlatching, the present invention can effectively prevent pedestrian or the article well that falls, but also can to pedestrian and vehicle, send alarm signal in several ways.Thoroughly eliminate the potential safety hazard that manhole cover loss causes, thereby guaranteed people's safety.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the invention will be further described.

Fig. 1 is sectional view of the present invention;

Fig. 2 is the state of the present invention while opening;

Fig. 3 is the connection diagram of lamp stand and walling crib;

Fig. 4 is the structural representation of safety net.

In figure, each label is: 1, walling crib, 2, well lid, 3, safety net, 4, alarm lamp, 5, noctilucence float, 6, screen frame, 7, hook, 8, safety net link, 9, lamp stand, 10, lamp stand limiting plate, 11, torsionspring, 12, rotating shaft, 13, limit switch.

The specific embodiment

Referring to Fig. 1～Fig. 4, the present invention is by walling crib 1, well lid 2, safety net 3, alarm lamp 4, noctilucence float 5, screen frame 6, hook 7, safety net link 8, lamp stand 9, lamp stand limiting plate 10, torsionspring 11, rotating shaft 12.

Referring to Fig. 1, before well lid 2 is opened, below alarm lamp 4 is pressed in by well lid 2, now alarm lamp 4 is not worked.Referring to Fig. 3, lamp stand 9 is hinged by rotating shaft 12 with the annular convex rib of walling crib 1 inner side, two ends and the annular convex rib of rotating shaft 12 are rotationally connected, middle part is connected with lamp stand 9, in rotating shaft 12, be provided with torsionspring 11, when well lid 2 is opened, lamp stand 9 is upwards upset under the effect of torsionspring 11, after holding up, by lamp stand limiting plate 10, undertaken spacing, the limit switch 13 that is simultaneously arranged on lamp stand 9 lower ends contacts and is triggered with lamp stand limiting plate 10, so alarm lamp 4 starts flicker warning (battery and drive circuit are installed in alarm lamp 4).

The concrete switch of implementing Times warning lamp 4 also can adopt turn switch, and turn switch is arranged on to rotating shaft 12 places, and the rotation by lamp stand 9 triggers.

Major function:

Generally, well lid has following protection and cautionary measure after opening:
