[0023] like Figure 1-5 As shown, a wellhead protection device disclosed in this technical solution is used for wellhead protection.

[0024] Specifically, please refer to Figure 1 - Figure 5 , the wellhead protection device specifically includes:

[0025] The protective chassis 1 includes a basic ring frame 5, a bottom ring frame 6 is provided below the basic ring frame 5, the basic ring frame 5 and the bottom ring frame 6 are fixedly connected by a connecting vertical rod 7, the inner sides of the basic ring frame 5 and the bottom ring frame 6 are fixedly connected with a protective grille 8, an outer ring frame 9 is provided on the outer side of the basic ring frame 5, and the basic ring frame 5 and the outer ring frame 9 are fixedly connected by a connecting cross bar 10;

[0030] The wellhead protection device provided by the utility model is designed so that after the device is unfolded,

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please refer to Figure 1 - Figure 5 , a wellhead protection device, comprising:

[0034] The protective chassis 1 includes a basic ring frame 5, a bottom ring frame 6 is provided below the basic ring frame 5, the basic ring frame 5 and the bottom ring frame 6 are fixedly connected by a connecting vertical rod 7, the inner sides of the basic ring frame 5 and the bottom ring frame 6 are fixedly connected with a protective grille 8, an outer ring frame 9 is provided on the outer side of the basic ring frame 5, and the basic ring frame 5 and the outer ring frame 9 are fixedly connected by a connecting cross bar 10;

[0035] The movable top frame 2 is arranged at a position above the protective base frame 1. The inner side of the movable top frame 2 is fixedly connected to the support frame 13. The middle part of the support frame 13 is detachably provided with a support rod 4. The lower end of the support rod 4 is plug-connected to the protective base frame 1, and the upper part of the support rod 4 supports the movable top frame 2.

[0036] Among them, the protective grille 8 on the inner side of the base ring frame 5 is arranged in a Feng shape, the protective grille 8 on the inner side of the bottom ring frame 6 is arranged in a cross shape, and the support frame 13 on the inner side of the movable top frame 2 is arranged in a cross shape;

[0037] The anti-skew traction rope 3 is arranged on the side of the protective base frame 1 and the movable top frame 2. There are multiple anti-skew traction ropes 3. The lower end of the anti-skew traction rope 3 is fixedly connected to the protective base frame 1, and the upper end of the anti-skew traction rope 3 is fixedly connected to the movable top frame 2;

[0038] The reflective strap is provided on the outside of a plurality of anti-slant traction ropes 3. The reflective strap includes an elastic strap 17. The two ends of the elastic strap 17 are detachably connected by a connecting buckle 18. The outside of the elastic strap 17 is evenly distributed and fixedly connected with reflective stickers 19.

[0039] Furthermore, a socket 12 is fixedly connected to the middle of the protective grille 8 on the inner side of the basic ring frame 5, and a limit seat 14 is fixedly connected to the middle of the support frame 13 on the inner side of the movable top frame 2. The lower end of the support pole 4 is plugged into the socket 12, and the upper end of the support pole 4 passes through the limit seat 14 and extends to the outer side of the upper end of the limit seat 14. The outer side of the support pole 4 is threadedly connected with a lifting nut 15, and the lifting nut 15 is located below the limit seat 14.

[0040] It can be seen that the lower part of the protective chassis 1 is composed of a cylindrical frame that can be inserted into the wellhead through the basic ring frame 5, the bottom ring frame 6, and the connecting vertical rod 7, so that the lower part of the protective chassis 1 can be inserted into the inlet to achieve positioning, effectively reducing the displacement of the protective chassis 1 due to collision, wind, etc. The external ring frame 9, the connecting cross bar 10 and the basic ring frame 5 form an extended platform to prevent the protective chassis 1 from falling into the well;

[0041] When in use, the protective base frame 1 is inserted into the position of the wellhead, the movable top frame 2 is lifted, and then the upper part of the supporting upright pole 4 is extended into the limiting seat 14, and the lower part of the supporting upright pole 4 is inserted into the inner side of the socket 12. The lower part of the supporting upright pole 4 is lifted by the socket 12, and the lifting nut 15 is moved upward by rotating the lifting nut 15. The movable top frame 2 is lifted and moved upward by the lifting nut 15 until the anti-skew traction rope 3 is straightened; thereby completing the installation of the device, and a warning effect is achieved by the erected movable top frame 2 and the anti-skew traction rope 3. The protective base frame 1 can effectively prevent people or objects from accidentally falling into the well;

[0042] After the device is installed, the reflective strap can be placed on the outside of multiple anti-slant traction ropes 3. When illuminated by light, the reflective sticker 19 reflects light, so that the device can be used in dimly lit areas and the warning effect of the device can be further enhanced.

[0043] Example 2:

[0044] The wellhead protection device provided in Example 1 is further optimized. Specifically, Figure 4 As shown, the upper end of the support frame 13 is fixedly connected with a storage buckle seat 16, and the support upright rod 4 can be buckled and connected with the storage buckle seat 16 after being removed.

[0045] Through the above structural design, after the device is used, the lifting nut 15 is rotated in the opposite direction to move the lifting nut 15 downward, so that the support pole 4 can be lifted upward, so that the lower end of the support pole 4 is separated from the socket 12, and then the support pole 4 is tilted and moved downward to achieve the disassembly of the support pole 4. After the support pole 4 is disassembled, the support pole 4 is buckled through the storage buckle seat 16 to achieve the storage of the support pole 4 after disassembly, thereby reducing the phenomenon of accidental loss of the support pole 4.

[0046] Example 3:

[0047] The wellhead protection device provided in Example 1 is further optimized. Specifically, Figure 3-Figure 5 As shown, connecting rings 11 are fixedly connected to the positions of the external ring frame 9 and the movable top frame 2 corresponding to the anti-skew traction rope 3. The ends of the anti-skew traction rope 3 are respectively connected to the connecting rings 11 at the same ends through buckles, making the connection of the anti-skew traction rope 3 more convenient.

[0048] Example 4:

[0049] The wellhead protection device provided in Example 1 is further optimized. Specifically, the anti-skew traction rope 3 can be any one of a steel wire rope, a nylon rope, and an iron chain.

[0050] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
