Abstract

The utility model relates to a novel anti-floating locking apparatus for an inspection well cover. The apparatus comprises an inspection well cover, an inspection well wall, a fixed iron plate, a hollow fixed screw and a fixed bolt, wherein the fixed iron plate is fixed on the inspection well wall through a plurality of expansion bolts, the hollow fixed screw is welded in the center of the fixed iron plate, the inspection well cover covers on the top part of the inspection well wall, and the fixed bolt penetrates the inspection well cover and is screwed with the hollow fixed bolt. By using the novel anti-floating locking apparatus for the inspection well cover, the inspection well cover can be fixed, such that the inspection well cover will not be pushed up when sewage overflow caused by water volume sudden increase or at low-lying places occurs, thereby preventing the inspection well cover from floating away and pedestrians and vehicles from falling into the well, and ensuring safety of the pedestrians and vehicles. Moreover, the apparatus can have obvious antitheft effects when being used in cast iron well covers.

Description

The anti-floating locking device of a kind of novel manhole cover

Technical field

The utility model relates to a kind of inspection shaft lid structure, is specifically related to the anti-floating locking device of a kind of novel manhole cover, belongs to municipal drainage facility technology field.

Background technology

Traditional inspection shaft lid adopts cast iron quality usually, yet the inspection shaft lid of cast iron is easy to stolen, and pedestrian, vehicle are caused security threat.

At present; both at home and abroad in each metropolis; the inspection shaft lid of various composite materials uses very general; but; reasons such as, city waterlogging low owing to the inspection shaft physical features, heavy rain ponding; usually can take place that water level rises in the inspection shaft, hydraulic pressure is excessive, cause the inspection shaft lid floating and break away from inspection shaft, can cause security threat to pedestrian, vehicle equally like this.

Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel manhole cover anti-floating locking device, to overcome described defective of the prior art.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of use safety, the anti-floating locking device of the novel manhole cover of good anti-theft effect.

For achieving the above object, the technical scheme that the utility model is taked is: the anti-floating locking device of a kind of novel manhole cover, and it comprises inspection shaft lid, the inspection shaft borehole wall, fixedly iron plate, hollow standing screw and set bolt; Wherein, described fixedly iron plate is fixed on the inspection shaft borehole wall by some expansion bolts; Described hollow standing screw is welded in the fixedly central authorities of iron plate; Described inspection shaft is placed on the top of the inspection shaft borehole wall; Described set bolt passes described inspection shaft lid, and can and hollow standing screw be screwed.

The anti-floating locking device of novel manhole cover of the present utility model further is set to: described fixedly iron plate is provided with a circle kink, and described kink is connected on the inspection shaft borehole wall; Described expansion bolt passes described kink.

Compared with prior art, the utlity model has following beneficial effect: the anti-floating locking device of novel manhole cover of the present utility model can be fixing with the inspection shaft lid, in case the generation water yield is uprushed or the low sewage that causes of physical features overfills, inspection shaft lid will be not can jack-up, prevent pedestrian, the vehicle security incident that floating disengaging inspection shaft causes mistake to weigh down inspection shaft because inspection shaft covers on the road, thereby guaranteed the safety of pedestrian, vehicle; Equally, for casting iron well lid, utilize this device, also can produce tangible anti-theft effect.

Description of drawings

Fig. 1 is the schematic diagram of the anti-floating locking device of novel manhole cover of the present utility model.

The specific embodiment

See also shown in the Figure of description 1, the utility model is the anti-floating locking device of a kind of novel manhole cover, and it is by inspection shaft lid 1, the inspection shaft borehole wall 2, fixedly several parts such as iron plate 3, hollow standing screw 4 and set bolt 5 are formed.

Wherein, described fixedly iron plate 3 is fixed on the inspection shaft borehole wall 2 by some expansion bolts 6.Specifically, described fixedly iron plate 3 is provided with a circle kink 31, and described kink 31 is connected on the inspection shaft borehole wall 2; Described expansion bolt 6 passes described kink 31 and is fixed in the inspection shaft borehole wall 2, and iron plate 3 is positioned on the inspection shaft borehole wall 2 thereby make fixedly.

Described hollow standing screw 4 is welded in the fixedly central authorities of iron plate 3.

Described inspection shaft lid 1 is placed on the top of the inspection shaft borehole wall 2.

Described set bolt 5 passes described inspection shaft lid 1, and can and hollow standing screw 4 be screwed.This set bolt 5 is stainless steel set bolt 5.

The mounting method of the anti-floating locking device of novel manhole cover of the present utility model is as follows: the top that inspection shaft lid 1 is placed on the inspection shaft borehole wall 2, set bolt 5 is covered 1 center drilling from inspection shaft to probe into, with hollow standing screw 4 combinations, manual capturing position is fixed earlier, carry out fastening with inner hexagon spanner then, so far, inspection shaft lid 1 is connected with fixing iron plate 3.

The anti-floating locking device of novel manhole cover of the present utility model can build inspection shaft 1 to be fixed, in case the generation water yield is uprushed or the low sewage that causes of physical features overfills, inspection shaft lid 1 will be not can jack-up, prevented that pedestrian on the road, vehicle from covering the security incident that 1 floating disengaging inspection shaft causes mistake to weigh down inspection shaft because of inspection shaft, thereby guaranteed the safety of pedestrian, vehicle; Equally, for cast iron inspection shaft lid 1, utilize this device, also can produce tangible anti-theft effect.

The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
