Description
Technical field
The utility model relates to a kind of protector, particularly relates to a kind of well head safe protector.
Background technology
Nowadays, following well mouth covers with a casting iron well lid usually, because casting iron well lid damages or the incident of losing often takes place, causes security incident constantly to occur.Now, some having occurred the well lid of anti-theft measure, but still can not guarantee that well lid can not lose or damage, and now is badly in need of a kind ofly after well lid is lost, and can cover well head, guarantees the device of pedestrian or vehicle safety.At present, China Patent No. is that the utility model patent of ZL00222759 has been announced a kind of safety device that is used for wellhole aperture, ground, be interconnected to the overall structure that the complete cover cap in wellhole aperture can be lived by at least two cell cubes through the opening and closing type syndeton, each cell cube is connected with the syndeton that is fixed in place, wellhole aperture through movable syndeton respectively.The problem that this patent exists is, the one, a plurality of opening and closing type syndetons are interconnected to constitute net structure, and when going into the well work for needs, it is cumbersome to open this structure, the 2nd, this opening and closing type syndeton is made by flexible material, therefore also has potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of safety good, and well head safe protector easy to use.
A kind of well head safe protector, but it is characterized in that it comprises that one can cover the plication opening-closing structure of well head, and this opening-closing structure flexibly connects with a linkage that is fixed in well head.
Above-mentioned linkage is one to be fixed in the circular groove rail that extends along the whole circumference direction of well head.
Above-mentioned circular groove rail has a breach that matches with the opening-closing structure profile.
Above-mentioned opening-closing structure comprises the fan box of a lateral opening, breach on the top of described fan box and the above-mentioned circular groove rail is hinged, the other end is fixed with annulus, also have several ribs of the fans in the described fan box, chain is installed between the ribs of the fan, above-mentioned ribs of the fan one end and above-mentioned annulus flexibly connect, and the other end and above-mentioned circular groove rail flexibly connect.
Above-mentioned ribs of the fan is bar-shaped or sheet.
Advantage of the present utility model is, first ribs of the fan of pulling of lateral opening from the fan box, first ribs of the fan drives all the other ribs of the fans through chain and launches along the circular groove rail, and first ribs of the fan and fan box opposite side fastened or pin with lockset, constitute an integrated carrying face and cover whole well head, in the time of need driving a well or go into the well work, as long as will detain or lockset is opened, ribs of the fan is closed into fan box, and will fan box pull downwards to the well head upright position, but in the lower going-into-well, the utility model adopts fan box and sheet or bar-shaped ribs of the fan to constitute the integral body of a covering well head along the circular groove rail in addition, this structural bearing capacity is big, and the intensity height is safe and convenient to use.The utility model is reasonable in design, and is easy to use and simple in structure, cost is low, helps large scale application.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode figure.
The specific embodiment
Following structure accompanying drawing is further described the utility model:
As shown in Figure 1, 2, the utility model comprises an opening-closing structure 1 and linkage 2, and described linkage 2 is one to be fixed in the annulus of well head, and there is a circular groove rail 3 that extends along the whole circumference direction this annulus inboard.One breach 4 that matches with opening-closing structure 1 profile is arranged on the circular groove rail 3.
Described opening-closing structure 1 has a fan box 5, fan box 5 one lateral openings, its top is connected on the breach 4 of circular groove rail 3 by loose-leaf or rotating shaft, can make fan box 5 become perpendicular or parallel state with the well head face, when fan box 5 is parallel with well head, the breach of these fan box 5 tops and circular groove rail 3 fits like a glove, and makes circular groove rail 3 complete closures.Be fixed with annulus 6 at fan box 5 other ends, this annulus 6 runs through and is fixed in the closed side of fan box 5 from fan box 5 closed sides and open side level.In fan box 5,8 above sheets or bar-shaped ribs of the fan 7 are arranged, iron chains or the chain made of other hard materials 8 with one or more between the ribs of the fan 7 connect, the above-mentioned ribs of the fan 7 one end levels of being through run through on the annulus 6 of fanning box 5, and the other end has a dome, and this dome is packed in the circular groove rail 3.
The utility model in use, circular groove rail 3 is installed on well head, in the time of will fanning box 5 and pull back level, can pull out ribs of the fan 7 in succession from fan box 5 opening parts, make ribs of the fan 7 along circular groove rail 3 rotary expansions, the another side of article one ribs of the fan with fan box 5 fastened or pin with lockset, and the circular bearing surface that forms a complete closure covers well head.In the time of need going into the well, will detain or lock and open, and ribs of the fan 7 be closed up in fan box 5, and will fan box 5 and pull downwards to vertical with well head, the people can be not interrupted about well head.The utility model can use with existing well lid collocation in use in addition, also can be installed on well head separately and use.
