Abstract
An inspection well seat comprises an inner-ring type supporting table which is arranged on an opening portion and used for containing an inspection well lid. The inspection well seat is characterized in that a protection net is fixedly arranged at the position, below the supporting table, of the well wall through expansion bolts, and a danger flag is arranged at the position, below the supporting table, of the well wall through other expansion bolts and a spring; and the danger flag is located between the protection net and the well lid. Due to mounting of the spring, the danger flag can automatically stretch out of an inspection well under the elastic action to be erected upwards. A reflecting marking strip is arranged on the danger flag. By the adoption of the inspection well seat, after the inspection well lid is lost, the danger flag can automatically stretch out of the inspection well instantly to be erected upwards, and pedestrians and vehicles are cautioned to pay attention, so that falling or car accidents are prevented from happening. After the well lid is damaged or lost, the internally-arranged protection net can effectively prevent the pedestrians and wheels from falling off, and the safety performance is improved in a doubled manner. The inspection well seat has the advantages of being simple in structure, easy to mount and good in protection effect.
Description
Technical field
The present invention relates to urban operating mechanism technical field, be specially a kind of inspection well seat.
Background technology
Existing inspection well cover, by the extruding of loaded vehicle, easily damages, and causes pedestrian and vehicle to be degenerated or traffic accident, has a strong impact on public safety.
Summary of the invention
The object of the invention is: for solving the problem, a kind of inspection well seat is provided.
The technical solution adopted in the present invention is: a kind of inspection well seat, comprise and be arranged on oral area for placing the brace table of ring type in inspection well cover, it is characterized in that: the borehole wall below described brace table is fixed with protective screening by expansion bolt, the borehole wall below described brace table is also fixed with danger flag by other expansion bolt and spring, described danger flag is between protective screening and well lid, and the installation of described spring should make described danger flag upwards hold up at elastic force effect meeting auto-extending inspection shaft.
Described danger flag is provided with reflecting marking bar.
Adopt after the present invention, after inspection well cover is lost, danger flag can auto-extending inspection shaft and upwards holding up immediately, and warning pedestrian and vehicle are noted, prevents from degenerating or the generation of traffic accident; Built-in protective screening, after well lid damages or loses, effectively can avoid the degeneration of pedestrian and wheel, dual lifting security performance.There is structure simple, be easy to install, the advantage that protected effect is good.
