Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] Such as Figure 1~3 As shown, the present invention includes a top cover 1 and a first channel steel 3, and the wellhead of the present embodiment is quadrangular. The bottom surface of the frame body is seated on a solid concrete foundation, and the first channel steel 3 at the same level as the dam road surface is fixed on the four sides of the well frame 2, and the top cover 1 is accommodated in the groove formed by the first channel steel 3. Cover the well frame 2, the upper surface of the top cover 1 is at the same level as the first channel steel 3 and the dam road surface, so as to avoid traffic accidents and prevent artificial prying. The bottom surface of the first channel steel 3 is facing the well head, and holes 4 are opened on the bottom surfaces of the first channel steel 3 on any two opposite sides. The top cover 1 is provided with a f...

The invention relates to a device for protecting a wellhead of a well, in particular to a cipher well cover for protecting a well type mounting instrument of a dam. The device comprises a top cover and a first channel steel; the periphery of the surface of a well frame is fixedly provided with the first groove steel which is in the same level with the road surface of the dam; the top cover is accommodated in a groove formed by the first groove steel and covers the well frame; the upper surface of the top cover, the first groove steel and the road surface of the dam are in the same level; a fastening device fixedly connected with the first groove steel is arranged on the top cover; four sides of the surface of the quadrangular well frame are welded with the first groove steel respectively;the underside faces towards the wellhead, wherein the undersides of the first groove steels of any opposite sides are provided with holes; one side of the lower surface of the top cover is fixedly connected with an insertion plate which is inserted into the hole to form hinge connection; the fastening device comprises a plurality of bolts and locking sheets which are evenly distributed on one side of the top cover; and the locking sheet is a superior arc surface and is fixedly connected with the bolt. The device has a cover plate type structure and has the characteristics of wide application range, large protective effort, good protective effect, damage prevention and the like.
Description
technical field [0001] The invention relates to a wellhead protection device for a well, in particular to a coded well cover for protecting instruments installed in a well on a dam. Background technique [0002] There are often some well-installed instruments on the reservoir dam surface road to monitor the safety of the dam. In order to ensure the normal and safe operation of the instrument, for many years, people often adopt the method of building bosses on the dam surface road to ensure the safe operation of the monitoring instrument. However, because the built boss structure affects the traffic safety of the road on the dam surface, collision accidents of people or vehicles often occur during operation, which seriously affects the safe operation monitoring of the dam. In addition, the boss structure on the dam surface road will also affect the appearance of the road. [0003] Due to the various disadvantages of the boss structure, in recent years, people have adopted t...
