According to the anti-falling inspection well cover, due to the fact that the hook caps tightly matched with the hook ends of the hooks are arranged, after the soft net bag is hooked on the hooks through side ropes, the hook ends are sleeved with the hook caps in a tight matching mode, and openings of the hooking grooves can be covered with the cover plates on the hook caps to prevent the side ropes from accidentally falling, and connection between the soft net bag and the well cover seat ring is safe and reliable; when people need to take down the soft net bag to overhaul or dredge an inspection well, only the hook caps need to be pulled off, so that the soft net bag is convenient to take down.
Description
Technical field
The utility model relates to a kind of municipal drainage facility, specifically relates to a kind of inspection well cover, particularly a kind of anti-fall inspection well cover.
Background technology
Along with the development in city and the propelling of urbanization, the drainage system under urban road and road and various pipeline spread all over town and country, cause inspection shaft to spread all over equally each corner in cities and towns.For the sake of security, on catch pit port, be equipped with inspection well cover.But often there will be the stolen situation of well lid; On the other hand, due to the rolling, impact of vehicle, cause well lid fracture and damaged, and rainwater, sewage gush and wash well lid open, the hidden danger that all can cause pedestrian to fall.For fear of occurring that pedestrian's well head that accidentally drops causes human casualty accident, notification number is to disclose a kind of Antifalling down net for manhole in the utility model patent of CN 2718075Y, comprise well seat, the soft string bag being connected with well seat, the described string bag is restricted and is connected through hole default on well seat by limit.By the string bag is set, the personnel in the inspection shaft that accidentally drops are protected.But the dismounting of this connected mode is very inconvenient, when inspection shaft being overhauled or being dredged as needs by pretty troublesome.Also have plenty of by a plurality of hooks are set at the borehole wall, the string bag is restricted and is directly hung on hook by limit.Although the string bag is conveniently installed or taken off to this connected mode, the string bag is easy accidental also, loses protective effect.
Utility model content
The purpose of this utility model is to provide a kind of string bag to connect i.e. reliable anti-fall inspection well cover for convenience detach again for overcoming the deficiencies in the prior art.
For achieving the above object, the utility model provides a kind of anti-fall inspection well cover, comprise well lid body, well lid seat ring and the soft string bag, the described soft string bag and well lid seat ring removably connect, it is characterized in that: described well lid seat ring inwall is provided with a plurality of hooks and hook cap, described hook upper end is provided with recessed hanging groove near a side of well lid seat ring inwall, opposite side is provided with the chimoto upwarping, described hook cap is provided with a cavity with chimoto phase close-fitting, on described hook cap, be also provided with the cover plate that extends laterally out, the position of described cover plate is corresponding with hanging groove.
Anti-fall inspection well cover of the present utility model, hook cap due to the chimoto phase close-fitting that is provided with and links up with, when the described soft string bag by limit, restrict hang over hook upper after, be enclosed within on chimoto hook cap close-fitting, cover plate on hook cap partly covers and on the aperture position of hanging groove, can prevent well limit rope accidental, and the soft string bag is connected safe and reliable with well lid seat ring; When will inspection shaft being overhauled or be dredged and need take off the soft string bag time, only need pull up hook cap and can take off easily the soft string bag.
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is further described
