[0002] In the construction, municipal maintenance, oil and gas exploitation industries, the safety protection of wellhead is crucial. The traditional wellhead protection method often uses a simple cover plate or fence, but these methods have many shortcomings. For example, the cover plate is easy to be moved or damaged by mistake, causing the wellhead to be exposed, which poses a safety hazard; although the fence can block the wellhead, it is not eye-catching enough, especially at night or in poor visibility environments, it is difficult to attract people's attention, thereby increasing the risk of accidental falling or debris falling into the wellhead.

[0003] To solve the above problems, some new wellhead warning devices have appeared on the market. These devices usually include a pad laid above the wellhead and a protective net frame fixed below the pad to prevent debris from falling into the wellhead. However, these devices still need to be improved in terms of warning effect and portability. For example, some devices lack obvious warning signs, making it difficult to be discovered in time at night or in poor visibility; another device has a warning sign, but the overall structure is bulky and not convenient for transfer and reuse on site.

[0020] In order to make the purpose, technical scheme of the utility model to carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the drawing to the utility model embodiment carries out further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, rather than all the embodiment, only to explain the embodiment of the utility model, and does not use to limit the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0021] Please refer to Figures 1 to 6 The utility model provides a technical scheme: a warning device, including the backing plate 1 for laying above the well mouth, the bottom surface of backing plate 1 is fixed with the protective net frame 2, the inner wall of backing plate 1 is fixed with the connecting rod 4, one end of connecting rod 4 is fixed in the surface of the suspension plate 3, the suspension plate 3 is circular ring plate structure, connecting rod 4 is equipped with multiple, multiple connecting rod 4 is distributed around the suspension plate 3, the surface of suspension plate 3 is inserted with the riser 7, both ends of riser 7 are fixed with the screw joint disc 6, the screw joint disc 6 is screwed in the surface of suspension plate 3, the top surface of suspension plate 3 and the bottom surface of suspension plate 3 are all set with screw joint groove 5, and the screw joint groove 5 is connected with the screw joint disc 6; the surface of screw joint disc 6 is set with the grabbing groove 9, and the surface of grabbing groove 9 is fixed with handle rod 10.

[0022] When using, the protective net frame 2 is inserted into the well mouth, and the backing plate 1 is overlapped above the well mouth, at this time, the backing plate 1 and the protective net frame 2 jointly protect the construction well mouth, and the protective net frame 2 avoids sundries from falling into the well mouth;After the multiple connecting rod 4 connects the suspension plate 3, the space between the adjacent two connecting rod 4 can also block the bulky articles, at least can avoid the person from stepping into the protective net frame 2;Step on the backing plate 1, then hold the handle rod 10 and rotate the screw joint disc 6 to separate from the screw joint groove 5, then pull out the riser 7 upward, until the lower screw joint disc 6 reaches the screw joint groove 5 below the suspension plate 3, then rotate the riser 7 to drive the lower screw joint disc 6 to be screwed in the screw joint groove 5 below the suspension plate 3, at this time, the riser 7 extends out of the well mouth, and plays a warning role.

[0023] The surface of riser 7 is fixed with the reflective warning strip 8, the reflective warning strip 8 is equipped with multiple, and multiple reflective warning strips 8 are distributed around the riser 7 as the central axis;The reason why the reflective warning strip 8 is arranged on the surface of riser 7 is to facilitate watching the existence of riser 7 at night.

[0024] The backing plate 1 is annular plate structure, the top surface of backing plate 1 is set with the embedded groove 11, the embedded groove 11 is spherical groove, and the spherical wheel 12 is rotatably connected in the embedded groove 11;The reason why the spherical wheel 12 is embedded on the top of backing plate 1 is to turn over the backing plate 1 and the protective net frame 2 after the backing plate 1 and the protective net frame 2 are removed from the well mouth, at this time, the spherical wheel 12 contacts the ground, and the protective net frame 2 can be pushed to move on the site.

[0025] The use process of the warning device is as follows:

[0026] Firstly, the construction wellhead position needing protection is determined, the area around the wellhead is ensured to be safe, and there is no other obstacle. It is checked whether all parts of the warning device are complete and intact, including the base plate 1, the protection net frame 2, the hanging plate 3, the connecting rod 4, the screw plate 6, the vertical pipe 7, the reflective warning strip 8, the handle rod 10 and the spherical wheel 12. The base plate 1 is laid on the wellhead, and it is ensured that the center of the base plate 1 is aligned with the center of the wellhead. At this time, the protection net frame 2 is located below the wellhead and plays a preliminary protection role to prevent sundries from falling in. The screw plate 6 is screwed on the hanging plate 3 by rotating the handle rod 10. According to the depth of the wellhead, the vertical pipe 7 is extracted upwards until the screw plate 6 below reaches the screw groove 5 position at the bottom surface of the hanging plate 3. At this time, the handle rod 10 is rotated again to screw the screw plate 6 below on the bottom surface of the hanging plate 3. The reflective warning strips 8 are evenly pasted on the surface of the vertical pipe 7 to ensure that they can be clearly identified at night and play a warning role. After the vertical pipe 7 extends out of the wellhead, its height and the eye-catching reflective warning strips 8 effectively remind personnel to pay attention to the safety of the wellhead and avoid accidents. When the construction is completed or the warning device needs to be moved, the handle rod 10 is first rotated to make the screw plate 6 separate from the screw groove 5, and then the vertical pipe 7 is pulled downwards until it is completely removed. The base plate 1 and the protection net frame 2 are turned over as a whole, and the spherical wheel 12 contacts the ground. The base plate 1 and the protection net frame 2 are easily pushed to a new working site or a storage position by using the rolling property of the spherical wheel.

[0027] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
