Abstract
The utility model relates to a safe manhole cover, which comprises a base, a cover plate and a cover plate-opening mechanism, the cover plate is placed on or hinged with the base, the longitudinal inner surface of the base and the longitudinal outer surface of the cover plate are shaped like inverted cones and matched with each other, and a crisscross or combined triangle-shaped or combined polygon-shaped safety protection frame is arranged in the base. Since the safety protection frame is added in the base, once the cover plate of the manhole cover is damaged or lost, a passerby or a vehicle passing the manhole cover cannot fall into a manhole to get injured or damaged because of the existence of the safety protection frame, and thereby potential safety hazards caused by the lost or damaged cover plate of the manhole cover can be effectively prevented.
Description
One, technical field
The utility model relates to municipal infrastructure articles for use, is specifically related to a kind of Safety well cover.
Two, background technology
The well head of ground various sewage well, manhole needs well lid to cover, in order to prevent that well lid from suffering damage with stolen, mainly be itself to take corresponding safeguard procedures from syndeton between the cover plate of well lid self and the well seat and well lid material, these measures have just increased undermined and stolen difficulty, but in case take place stolen or damage, people's car very easily takes place fall into accident in the well.
Three, utility model content
The purpose of this utility model provides a kind of Safety well cover, avoid people's car takes place falling into accident in the well because of well lid damages or loses, for achieving the above object, the Safety well cover that the utility model provides, a kind of Safety well cover, comprise base, cover plate and cover plate opening mechanism, cover plate is laid or is hinged on the base, and the vertical external surface of base longitudinal inner surface and cover plate is the back taper coupling, is provided with groined type in the base, or combined triangular shape, or make up polygonal security protection frame.
Flexibly connect between security protection frame and the base, base inner surface and external surface are provided with flange.The security protection frame also can be taked to fixedly connected with the connected mode between the base.Base inner surface flange be used to support cover plate, the flange of base outer surface is used in ground fixing.
The cover plate opening mechanism is a cover plate open hole, or is a plurality of open holes, also opens ring, can be as the cover plate opening mechanism as long as can be used in the setting of opening cover plate.
The shape of base, cover plate can be chosen as circle, also can be chosen as square.
The security protection frame can be the groined type skeleton, or is the polygon skeleton, or is combined triangular shape skeleton, also can select the skeleton of other shapes for use.
The base of well lid and cover plate be shaped as circle the time, base aperture is a circular hole.The base of well lid and the shape of cover plate also can be made into square, and base aperture is a square opening.
The utility model adopts and add security protection frame method in base, in case the cover plate of well lid suffers damage or loses, when pedestrian or this well lid of vehicle process, because the existence of security protection frame, be unlikely to fall in the well and sustain damage or damage, effectively avoid losing or damaging the potential safety hazard of bringing because of the well lid cover plate.
