Abstract
The utility model discloses a waterproof backflushing safety inspection well lid device which comprises a well base, a well lid arranged on the well base, and a turnbuckle device arranged on the lower side of the well lid, wherein the well base is hinged to one end of the well lid, the turnbuckle device comprises a rotating shaft arranged on the lower side of the well lid, a transverse strip installed on the rotating shaft, and a rotating rod arranged at the end of the transverse strip, the rotating rod penetrates through an arc groove formed in the well lid, and the transverse strip can rotate along the arc groove through the rotating rod. When the waterproof backflushing safety inspection well lid device is rotated out of the edge of the well lid, one end of the transverse strip is located below a flange of the well base and in close fit with the flange, and the well lid hinged to the well base is firmly fixed to the well base; when the waterproof backflushing safety inspection well lid device is rotated to the end of the arc groove in the reverse direction, the transverse strip is disengaged from the flange of the well base, a turnbuckle is removed, and the well lid can be opened. The waterproof backflushing safety inspection well lid device is simple in structure, easy to assemble, capable of effectively preventing the phenomenon of separating the well lid from the well base due to backflushing of water, and suitable for city and road construction projects.
Description
Technical field
The utility model belongs to mechanized equipment and manufactures field and city and highway construction field, relates to a kind of waterproof recoil safety manhole lid arrangement, is specifically related to a kind ofly prevent that well water from rushing the manhole lid device that turns over well lid.
Background technology
Along with modern science and technology and socioeconomic fast development, urban construction is progressively accelerated, city size is in continuous expansion, different kinds of roads facility progresses into standardization, standardized management, many pipelines, netting twine progressively enter network of underground, thereby the market demand of manhole cover in urban planning and road construction constantly increases.Because well lid is the closure that leads to top, underground installation access, the communal facilitieies such as every urban road, speedway, tap water, draining, telecommunications, electric power, fire plug, valve all need installation check well lid.The material of manufacturing manhole cover is a lot, and composite plastic, steel concrete are used for light-duty well lid, and grey foundry goods and spheroidal graphite casting are used for plain edition and heavy well cover.Due to Summer Heavy Rainfall season, underground pipeline recoils to well lid because the water yield is excessive, makes well lid separated with well seat, and with regard to a lot of well lid well seats occurring because separated the causing of water recoil gulps down people's death incident, cause huge repercussion this year in the whole nation.The manhole cover device of the safety recoiling in the urgent need to a kind of energy waterproof.
Summary of the invention
technical problem:the utility model provides a kind of can preventing to cause the well lid waterproof recoil safety manhole lid arrangement separated with well seat because of water recoil.
technical scheme:waterproof recoil safety manhole lid arrangement of the present utility model, comprise well seat, be arranged on well lid and the spinner assembly that is arranged on well lid downside on well seat, well seat and well lid are at one end hinged, spinner assembly comprises the rotating shaft that is arranged on well lid downside, be arranged on horizontal stripe and the swing arm that is arranged on horizontal stripe end in rotating shaft, swing arm is through the arc groove arranging on well lid, horizontal stripe can rotate along arc groove by swing arm, when screwing out well lid edge, horizontal stripe one end is positioned at the flange below of well seat tight fit with it, the well lid hinged with well seat is securely fixed on well seat, when in the other direction, be threaded to the end of arc groove, horizontal stripe departs from the flange of well seat, spinner is removed, well lid can be opened.
This waterproof recoil safety manhole lid arrangement, its turn buckle device consists of following three parts, is respectively horizontal stripe, rotating shaft and swing arm.Due to horizontal stripe and well seat flange employing tight fit, improved the stability of horizontal stripe fastening well seat, and two horizontal stripes of design are away from bolt, symmetrical along center line, more guaranteed the ability that this device opposing well water recoils.When swing arm rotates to an angle along arc track on well lid, make horizontal stripe screw out well seat flange, spinner is removed, and well lid can be separated with well seat around bolt.
beneficial effect:the utility model compared with prior art, has the following advantages:
Common anti-stealing manhole cover, its well lid relies on gravity to be sitting on well seat, there is no locking device, and when in hoistway, well water recoils, well lid is separated with well seat, has serious potential safety hazard.Thereby the utility model designs a spinner assembly between well lid and well seat, well lid and well seat is locked.
The utility model device has and prevents from causing the well lid function separated with well seat because of water recoil, simple in structure, easy and simple to handle.The utility model is by respectively adding a circular bosses in well lid two bottom sides, by rotating shaft, horizontal stripe is connected with well lid boss, by horizontal stripe, well seat and well lid are fixed again, while making well lid below be subject to well water recoil, horizontal stripe and well seat closely cooperate, well lid and well seat are stuck, thereby overcome because well water recoils, cause the well lid phenomenon separated with well seat.The functions such as that structure design of the present utility model also has is antitheft, anti-slip, vibration proof, low noise.

In figure, have: 1. well lid, 2. well seat, 3. horizontal stripe, 4. rotating shaft, 5. swing arm, 6. bolt, 7. arc groove, 8. flange.
The specific embodiment
Below in conjunction with Figure of description and embodiment, the utility model is done further and illustrated.
Waterproof recoil safety manhole lid arrangement of the present utility model, comprise well seat 2, be arranged on well lid 1 and the spinner assembly that is arranged on well lid 1 downside on well seat 2, well seat 2 and well lid 1 are at one end hinged, spinner assembly comprises the rotating shaft 4 that is arranged on well lid 1 downside, be arranged on horizontal stripe 3 and the swing arm 5 that is arranged on horizontal stripe 3 ends in rotating shaft 4, swing arm 5 is through the arc groove 7 arranging on well lid 1, horizontal stripe 3 can be by swing arm 5 along arc groove 7 rotations, when screwing out well lid 1 edge, horizontal stripe 3 one end are positioned at flange 8 belows the tight fit with it of well seat 2, the well lid 1 hinged with well seat 2 is securely fixed on well seat 2, thereby reach, prevent from causing well lid 1 object separated with well seat 2 because of well water recoil, when in the other direction, be threaded to the end of arc groove 7, horizontal stripe 3 departs from the flange 8 of well seat 2, and spinner is removed, and well lid 1 can be opened.
The utility model device comprises the well lid formation that matches with well seat, in well lid bottom surface, boss place is connected horizontal stripe by rotating shaft with well lid, horizontal stripe front end and well seat bottom closely cooperate, make well lid and the mutual fastening of well seat, thereby play, prevent from causing the well lid function separated with well seat because of water recoil, by swing arm, along arc groove on well lid, rotate to an angle, make horizontal stripe front end screw out well seat flange, realize well lid separated with well seat.
