Abstract
The invention discloses a washing-off-proof safety well lid which comprises a well seat and a round outer well lid installed on the well seat. An inner well lid is further arranged under the outer well lid, and fan blades of a sector structure are arranged on the periphery of the inner well lid, the inner well lid and the outer well lid are fixedly connected through a rubber layer, and a groove matched with the sector structure of the inner well lid is formed in the inner ring of the well seat. The well lid is simple in structure, convenient to operate, good in pressure resistance and shock resistance, good in stability and safe and reliable.
Description
Technical field
The present invention relates to a kind of well lid, be specifically related to a kind of anti-formula Safety well cover that washes away.
Background technology
Well lid is for covering on road or the fender of oil well etc., being used for preventing that people or thing from falling down, and is one of a kind of municipal administration and industrial widely used ancillary facility.At present, its structure of most of well lids comprises well seat and forms with individual layer/Double-layer drain cover plate of well seat scarf.Individual layer manhole cover plate, because vehicular traffic ceaselessly rolls, is easy to perk and even damages, and has potential safety hazard.Existing Double-layer drain cover complex structure, handling trouble, cost is higher, and large-scale load-carrying vehicle rolls process, is easy to generation and resonates and become flexible, and is easy to be washed away by flood.So people often adopt protective screening formula well lid to substitute above-mentioned well lid, but protective screening formula well lid erection procedure is loaded down with trivial details, mostly is fixedly well lid, needs special instrument unloading during replacing.So develop a kind ofly there is pressurized, shock resistance is strong, good stability, the anti-formula Safety well cover that washes away easy to loading and unloading, safe and reliable, has wide market prospects.
Summary of the invention
The technical problem to be solved in the present invention is to provide and anti-washes away formula Safety well cover, and this manhole cover structure is simple, easy to operate, and pressurized, shock resistance are strong, and good stability is safe and reliable.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
Prevent washing away formula Safety well cover, comprise well seat, be arranged on the rounded outer well lid on well seat, because adopt round manhole cover to be difficult for tilting, can protect preferably the safety of pedestrian and vehicle; Described outer well lid below is also provided with interior well lid, and interior well lid periphery is made as the fan sheet that is sector structure, between interior well lid and outer well lid, by rubber layer, is fixedly connected with; Described well seat inner ring is provided with the groove matching with interior well lid sector structure.
Preferably, the fan sheet of described interior well lid is 3, around interior well lid circumference equal dividing, distributes, to utilize 3 fan sheets to surround the principle that triangle is the most firm, make that well lid is subject to that large-scale load-carrying vehicle rolls, flood erosion or other extraneous factor be when affect, well lid is difficult for loosening, still can tightly lock.
Preferably, the width of described every fan sheet is 1/6 of interior well lid circumference, is to be easy to manufacture and coordination attractive in appearance for interior well lid.
Preferably, described interior well lid maximum gauge is slightly less than the diameter of outer well lid, is to be easy to operate in order to load and unload well lid.
Further, on described outer well lid and interior well lid, being equipped with drain hole, is in order to prevent ponding on well lid, to bring negative pressure to well lid.
Effective effect of the present invention is: the present invention can be by the rotation of outer well lid, in driving, fan sheet and the well seat inner ring of well lid closely pin, make that well lid is subject to that large-scale load-carrying vehicle rolls, flood erosion or other extraneous factor be when affect, difficult quilt has rolled or perk, avoided well lid to fall the possibility in well, strengthened the close fit fixation degree of well lid and well seat, add that interior well lid periphery is set to sector structure, further strengthened the fastening area between well lid and well seat, thereby increasing lifting surface area, alleviates the burden of well lid; The present invention has increased rubber layer between well lid and interior well lid outside, produces resonance while having avoided the extraneous factors such as large-scale load-carrying vehicle rolls to affect, thereby makes the loosening well lid of even damaging of well lid, has also weakened the impact of noise simultaneously; Simple in structure being easy to of the present invention manufactured, simple to operation, compares with protective screening formula well lid, saved loaded down with trivial details erection procedure; It is safe and reliable that the present invention prevents washing away formula Safety well cover, guaranteed when well lid is opened with fastening manually to complete, thus the possibility of further having avoided well lid to be washed away by flood.

Figure number explanation: 1, well seat; 2, outer well lid; 3, interior well lid; 4, rubber layer; 5, groove, 6, drain hole.
The specific embodiment
Accompanying drawing discloses concrete structure of the present invention without limitation, and below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, 2, prevent washing away formula Safety well cover, comprise well seat 1, be arranged on the rounded outer well lid 2 on well seat 1, because adopt round manhole cover to be difficult for tilting, can protect preferably the safety of pedestrian and vehicle; Described outer well lid 2 belows are also provided with interior well lid 3, and interior well lid 3 peripheries are made as the fan sheet that is sector structure, and interior well lid 3 is fixedly connected with by rubber layer 4 with 2 of outer well lids; Described well seat 1 inner ring is provided with the groove 5 matching with interior well lid 3 sector structures.The fan sheet of described interior well lid 3 is 3, around interior well lid 3 circumference equal dividings, distributing, is to utilize 3 fan sheets to surround the principle that triangle is the most firm, makes that well lid is subject to that large-scale load-carrying vehicle rolls, flood erosion or other extraneous factor be when affect, well lid is difficult for loosening, still can tightly lock.The width of described every fan sheet is 1/6 of interior well lid 3 circumference, is to be easy to manufacture and coordination attractive in appearance for interior well lid 3.Described interior well lid 3 maximum gauges are slightly less than the diameter of outer well lid 2, are to be easy to operate in order to load and unload well lid.On described outer well lid 2 and interior well lid 3, being equipped with drain hole 6, is in order to prevent ponding on well lid, to bring negative pressure to well lid.
The course of work of the present invention: according to dislocation principle, during use, rotate outer well lid 2, the fan sheet in driving on well lid 3 embeds and is placed in the groove 5 that matches on well seat 1, after rotation, fan sheet departs from groove 5 positions, clamps mutually with the inner ring of well seat 1.In the time of need to opening, rotate back into behind groove 5 positions, outer well lid 2 could be opened.
