[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1 , Figure 1 It is a structural schematic diagram of a wellbore protection device in an embodiment of the utility model, the wellbore protection device comprises a well pipe 1, a base 2 and a protection mechanism 4; the well pipe 1 is arranged in the wellhead; the base 2 is arranged on the outer periphery of the well pipe 1, and a plurality of limit columns 21 are arranged circumferentially on the outer periphery of the base 2, the upper end of the well pipe 1 passes through the base 2 and extends to above the base 2, and the upper end of the well pipe 1 is detachably connected with a fixing plate 3; the protection mechanism 4 comprises a protection cover 41, a clamping end 42 and a sealing plate 43; the outer periphery of the protection cover 41 is provided with a clamping end 42, the clamping end 42 is clamped on the limit column 21, and the protection cover 41 is used to shield the well pipe 1, and the upper end of the protection cover 41 is detachably connected with a sealing plate 43.

[0024] In this embodiment, a base 2 is provided on the outer periphery of the well pipe 1, and a limiting column 21 is arranged on the base 2. By slidingly connecting the protective cover 41 to the base 2, the engaging end 42 at the upper end of the protective cover 41 can be engaged with the limiting column 21 of the base 2, so that the entire protective cover 41 protects the pipe mouth of the well pipe 1. In this way, when the monitoring equipment is working inside the well pipe 1, it can be effectively protected.

[0025] In one embodiment, see Figure 1-2 In order to improve the installation efficiency of the protective cover 41, an annular slide groove 22 is provided on the base 2 and on the outer periphery of the well pipe 1, and the protective cover 41 is slidably connected in the slide groove 22. A slider 411 cooperating with the slide groove 22 is provided at the lower end of the protective cover 41. The clamping end 42 includes a connecting ring 421 and a plurality of clamping blocks 422. The connecting ring 421 is fixed to the outer periphery of the protective cover 41. The plurality of clamping blocks 422 are circumferentially arranged on the outer periphery of the connecting ring 421. A clamping notch 423 cooperating with the limiting column 21 is provided on the clamping block 422, and a bend end 424 is provided on the side of the clamping block 422 away from the connecting ring 421.

[0026] In this embodiment, a slide groove 22 is opened on the base 2, and a slider 411 is arranged at the lower end of the protective cover 41, so that the protective cover 41 can rotate circumferentially on the well pipe 1, and at the same time, a connecting ring 421 is fixed to the outer periphery of the protective cover 41, and a locking block 422 is provided on the connecting ring 421. By opening a locking notch 423 on the locking block 422, the protective cover 41 can be locked on the limiting column 21 through the locking notch 423 on the locking block 422 during the rotation process. The locking block 422 is a plastic deformable shell, and a prying end 424 is provided on the surface of the shell. The range of the locking notch 423 can be expanded by the prying end 424, so that it is convenient for the locking block 422 to no longer be locked on the limiting column 21, and it is convenient for the staff to disassemble it later.

[0027] In one embodiment, see Figure 3-4 To facilitate the installation of subsequent monitoring equipment, a first through hole 31 is provided on the fixing plate 3 for the piezometer cable 5 to pass through, and the lower end of the piezometer cable 5 is connected to the osmotic pressure water level gauge 6. A second through hole 431 is provided on the sealing plate 43. A plurality of threaded holes 44 are circumferentially provided on the protective cover 41 and the sealing plate 43, and connecting bolts 45 that connect the sealing plate 43 and the protective cover 41 are threadedly connected to the inner threads of the threaded holes 44.

[0028] In the present embodiment, the osmotic pressure water level meter 6 is actually a water level meter probe. When the probe contacts groundwater, it can sense the change in water pressure, obtain water layer thickness data based on calculation, and convert it into a water level value based on the surface elevation. The water level change can be obtained by monitoring the change in water layer thickness. Since the water level meter probe is a conventional device in this field, and the operation method and supporting equipment are also common knowledge of those skilled in the art, they are not described in detail. A first through hole 31 is opened on the fixing plate 3, and a second through hole 431 is opened on the sealing plate 43, so that the osmotic pressure meter cable 5 can be conveniently extended to the outside of the protective cover 41 and connected with other monitoring equipment, so as to facilitate the staff to view the monitoring data.

[0029] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the utility model is described in detail: after the staff has set up the osmometer 6 inside the well pipe 1, the staff connects the osmometer cable 5 to the osmometer 6, prompting the osmometer cable 5 to pass through the first through hole 31 of the fixing plate 3, and the staff connects the slider 411 at the lower end of the protective cover 41 to the slide groove 22, and makes the entire protective cover 41 shield the well pipe 1, driving the protective cover 41 to rotate circumferentially, and prompting the engaging notch 423 on the engaging block 422 to engage with the limiting column 21 of the base 2, and completes the connection between the base 2 and the protective cover 41 through the cooperation of the engaging block 422 and the limiting column 21, and then at the top of the protective cover 41, through the connecting bolt 45 connects the sealing plate 43 so that the piezometer cable 5 passes through the second through hole 431 and is connected to the external monitoring equipment. When the protective cover 41 needs to be disassembled as a whole later, it is only necessary to pull the bending end 424 to expand the engaging notch 423 on the engaging block 422 and make it no longer engage on the limiting column 21. Then, the entire protective cover 41 is driven to rotate in the opposite direction in the slide groove 22 and away from the limiting column 21. The protective cover 41 can be removed by pulling it upward. The protective cover 41 is easy to install and disassemble and can be reused. It can effectively protect the well pipe 1, greatly improving the safety of the monitoring equipment during use and avoiding damage.

[0030] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
