[0027] Example 1:

[0028] like Figures 1-3 As shown, this utility model provides a wellhead protection device 1 for well construction, including: a mounting plate 10 and a support frame. The mounting plate 10 is provided with an operating port 11 that extends through in the thickness direction. The support frame is constructed in multiple parts, and the multiple support frames are rotatably connected to the mounting plate 10 respectively. The multiple support frames are adapted to rotate around the center of the operating port 11. The support frame is provided with a support part and a movable clamping part. The support part is adapted to abut against the ground, and the clamping part can move to selectively clamp and cooperate with the well wall.

[0029] In some embodiments, the mounting plate 10 is provided with an operating port 11. The design of the operating port 11 allows construction personnel to perform various operations through this operating port 11, such as the transfer of materials or tools. Multiple support frames are provided (at least two), each rotatably connected to the mounting plate 10. The multiple support frames can rotate around the center of the operating port 11. Each support frame includes a support portion and a clamping portion. The support portion is adapted to directly contact the ground to support the entire protective device 1, ensuring that the protective device 1 is stably placed on the ground. The clamping portion is movable; by moving the clamping portion, it can be adjusted according to the specific dimensions of the well wall to achieve a tight fit between the clamping portion and the well wall.

[0030] Understandably, when installing the protective device 1, the support parts of the multiple support frames are first made to abut against the ground to stabilize the protective device 1. Then, the multiple support frames are rotated to make them spaced apart in the circumferential direction, and the protective device 1 is moved so that the operating port 11 is directly opposite the wellhead in the height direction. Then, the clamping parts are moved so that the multiple clamping parts are respectively clamped and fitted with the well wall. Since the multiple clamping parts are spaced apart in the circumferential direction along the well, the position of the protective device 1 in the horizontal direction can be fixed after the multiple clamping parts are respectively fitted with the well wall.

[0031] Therefore, the above-mentioned design avoids the need for connection points around the well, thus facilitating the installation of the protective device 1 and improving the construction efficiency of the well. Furthermore, by moving the clamping part, the protective device 1 can be adapted to wells of different diameters, improving its applicability.

[0032] According to the wellhead protection device 1 of this utility model, the supporting parts of multiple support frames are respectively engaged with the ground for abutment, and the pressing parts of multiple support frames are respectively spaced apart in the circumferential direction of the well and pressed tightly against the well wall, so as to prevent the protection device 1 from moving in the horizontal direction and fix the protection device 1 in the horizontal direction. Compared with setting connection points around the well, the protection device 1 of this application is simple to install and improves the installation efficiency of the protection device 1, thereby improving the construction efficiency of the well. At the same time, the protection device 1 of this application can adapt to wells of different diameters.

[0033] Example 2:

[0034] Based on Embodiment 1, the support frame in this embodiment includes: a connecting rod 21, a support rod 22, an adjusting rod 23, and a clamping rod 24. The connecting rod 21 extends horizontally and one end is rotatably connected to the mounting plate 10. The support rod 22 extends vertically, with its top connected to the connecting rod 21 and its bottom adapted to abut against the ground. The support rod 22 is configured as a support part. The adjusting rod 23 extends horizontally and one end is connected to the support rod 22. The clamping rod 24 is configured as a clamping part and is movably connected to the other end of the adjusting rod 23. The clamping rod 24 is adapted to move horizontally.

[0035] In some embodiments, the connecting rod 21 extends horizontally and one end of the connecting rod 21 is rotatably connected to the mounting plate 10 to allow the support frame to rotate around the center of the operating port 11. The support rod 22 is vertically arranged (the support rod 22 extends in the height direction), the top of the support rod 22 is connected to the connecting rod 21, and the bottom of the support rod 22 is used to contact the ground to ensure that the protective device 1 is placed firmly on the ground. The adjusting rod 23 also extends horizontally, one end of the adjusting rod 23 is connected to the support rod 22, and the clamping rod 24 is movably connected to the other end of the adjusting rod 23. The clamping rod 24 moves horizontally toward the support rod 22 to make the clamping rod 24 in close contact with the well wall.

[0036] Example 3:

[0037] Based on Embodiment 2, the adjusting rod 23 is provided with an adjusting channel that runs through the horizontal direction. The pressing rod 24 includes a first rod 241 and a second rod 242. The first rod 241 extends in the horizontal direction and a portion of the first rod 241 is movably disposed in the adjusting channel. The second rod 242 extends in the height direction. The top of the second rod 242 is connected to the end of the first rod 241 that is away from the support rod 22. The bottom of the second rod 242 protrudes from the support rod 22 in the height direction.

[0038] In some embodiments, the position of the second rod 242 relative to the support rod 22 in the horizontal direction can be adjusted by moving the first rod 241 within the adjustment channel. That is, during installation, the protection device 1 can be fixed in the horizontal direction by moving multiple first rods 241 to press multiple second rods 242 against the well wall, which facilitates the installation of the protection device 1.

[0039] According to some embodiments of the present invention, the inner peripheral wall of the adjustment channel is provided with a first thread, the outer peripheral wall of the first rod 241 is provided with a second thread that mates with the first thread, the second rod 242 is rotatably connected to the first rod 241, and the second rod 242 is adapted to rotate around the center of the adjustment channel.

[0040] Understandably, since the first thread on the inner circumferential wall of the adjusting channel engages with the second thread on the outer circumferential wall of the first rod 241, rotating the first rod 241 allows adjustment of its horizontal position relative to the support rod 22, thereby adjusting the horizontal position of the second rod 242 relative to the support rod 22. Of course, the engagement of the first and second threads prevents the first rod 241 from accidentally moving horizontally relative to the support rod 22, thus stabilizing the position of the second rod 242 and ensuring the stable installation of the protective device 1.

[0041] Example 4:

[0042] Based on Embodiment 3, this embodiment provides a first mounting position and a second mounting position spaced apart in the height direction for the support rod 22. The support frame also includes a linkage rod 25, one end of which is rotatably mounted at the first mounting position, and the other end of which is provided with a fixing hole 251. A fixing block 221 is provided at the second mounting position. The fixing hole 251 is fitted around the outer periphery of the fixing block 221 of an adjacent support rod 22 to fix the two adjacent support rods 22.

[0043] In some embodiments, the first mounting position and the second mounting position are spaced apart from each other in the height direction. Here, the first mounting position may be above the second mounting position or below the second mounting position, and there is no limitation.

[0044] Understandably, when the operating port 11 of the protective device 1 is directly opposite the wellhead in the height direction, and the multiple support rods 22 are rotated to be spaced apart in the circumferential direction, the user can rotate the linkage rod 25 to make the fixing hole 251 at the other end of the linkage rod 25 engage with the fixing block 221 on the adjacent support rod 22, thereby fixing the two adjacent support rods 22. Of course, by sequentially engaging the fixing hole 251 of the linkage rod 25 with the fixing block 221 on the adjacent support rod 22, all the support rods 22 can be linked and fixed, thereby improving the structural stability of the protective device 1.

[0045] It should be noted that after the fixing hole 251 on the linkage rod 25 cooperates with the fixing block 221 on the adjacent support rod 22, the linkage rod 25 can also act as a railing, that is, the linkage rod 25 can block the area between two adjacent support rods 22 to improve the safety protection capability of the protective device 1.

[0046] According to some embodiments of the present invention, the support frame further includes: a rotating sleeve 26, which is disposed at the first mounting position and rotatably sleeved on the outer periphery of the support rod 22. The outer peripheral wall of the rotating sleeve 26 is provided with a first connecting ear, which is rotatably connected to the linkage rod 25. The linkage rod 25 is adapted to rotate relative to the first connecting ear in the height direction.

[0047] In some embodiments, since the rotating sleeve 26 can rotate freely around the support rod 22 and the linkage rod 25 can rotate relative to the first connecting ear in the height direction, the linkage rod 25 has a higher degree of freedom, so that the fixing hole 251 on the linkage rod 25 can stably cooperate with the fixing block 221 on the adjacent support rod 22 to ensure the structural stability of the protective device 1.

[0048] It is worth mentioning that, despite the addition of more moving parts, the above design actually enhances the stability and robustness of the entire protective device 1. This is because each linkage 25 can be fine-tuned according to actual conditions, ensuring that the fixing hole 251 of each linkage 25 can engage with the fixing block 221 on the adjacent support rod 22, reducing the risk of loosening or instability.

[0049] In some embodiments, an adjusting sleeve is rotatably fitted around the outer periphery of the support rod 22. The adjusting sleeve is located in the second mounting position, and a fixing block is disposed on the outer peripheral wall of the adjusting sleeve. This allows the fixing block to easily cooperate with the fixing hole 251, thereby improving the installation efficiency of the protective device 1.

[0050] Example 5:

[0051] Based on Embodiment 4, this embodiment has a circumferential groove 12 on the outer peripheral wall of the mounting plate 10, and a slider is provided at the end of the connecting rod 21 away from the support rod 22. The slider is slidably received in the groove 12.

[0052] In some embodiments, the inner peripheral wall of the slide groove 12 can restrict the outer peripheral wall of the slider, thereby allowing the slider to move stably along the extending direction of the slide groove 12, and thus allowing the connecting rod 21 to rotate stably around the center of the operating port 11. Of course, the slider is slidably housed within the slide groove 12 so that the connecting rod 21 can stably engage with the mounting plate 10, thereby allowing the mounting plate 10 to stably connect and engage with the support frame, improving the structural stability of the protective device 1.

[0053] According to some embodiments of the present invention, the mounting plate 10 is further provided with a mounting port 13 communicating with the slide groove 12, and the slider can be selectively disposed in the slide groove 12 or detached from the slide groove 12 through the mounting port 13.

[0054] In some embodiments, when transporting or storing the protective device 1, the user can remove the slider from the slide groove 12 through the mounting port 13, thereby separating the mounting plate 10 from the multiple support frames, which reduces the volume occupied by the protective device 1 and facilitates its transport or storage. Of course, when the protective device 1 needs to be used, the user can receive the slider in the slide groove 12 through the mounting port 13, thereby connecting the mounting plate 10 to the multiple support frames for quick assembly of the protective device 1.

[0055] It is worth mentioning that users can increase or decrease the number of support frames connected to the mounting plate 10 according to actual needs, thereby improving the applicability of the protective device 1. Of course, if a support frame is damaged, the user can replace the corresponding support frame to avoid replacing the entire protective device 1, thus reducing the maintenance cost of the protective device 1.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
