[0037] Referring to Figures 1-7 , the present invention provides a protection device for a wellbore pipe structure, including a wellbore pipe 1, and further including:

[0038] A strengthening part is fixedly connected to the outer side wall of the wellbore pipe 1 along the axial direction, and a plurality of strengthening parts are provided, and the plurality of strengthening parts are circumferentially and equally spaced.

[0039] A casing 2 is sleeved outside the wellbore pipe 1 and covers the strengthening part. A connecting channel 211 is provided on the inner side wall of the casing 2, and a connecting component is provided on the outer side wall of the wellbore pipe 1. The connecting end of the connecting component extends into the connecting channel 211, so that the casing 2 has an elastic tendency away from the end of the wellbore pipe 1.

[0040] A connecting socket sleeve 3 is clamped at the end of the wellbore pipe 1, and the connecting socket sleeve 3 is relatively fixed to the casing 2. The wellbore pipe 1, the casing 2 and the connecting socket sleeve 3 enclose to form a sealing cavity 5.

[0041] A packing 4 is arranged annularly in the sealing cavity 5, and both ends of the packing 4 are respectively abutted against the strengthening part and the connecting socket sleeve 3.

[0042] In the present invention, a number of reinforcing parts are axially and fixedly connected to the outer peripheral side of the wellbore pipe 1, and the number of reinforcing parts are evenly distributed, so as to uniformly improve the structural strength of the wellbore pipe 1. When an external force acts on the wellbore pipe 1, it can effectively disperse the support, ensuring the effect of strengthening the structural support of the wellbore pipe 1. In addition, the number of reinforcing parts and the wellbore pipe 1 are covered by the casing 2, and an alternating elastic trend is formed between the casing 2 and the wellbore pipe 1 through the connecting component. Combining the connecting seat sleeve 3 and the packing 4 to fix the wellbore pipe 1 and the casing 2, so that a relatively fixed and elastic trend interaction is formed between the wellbore pipe 1 and the casing 2, enhancing the connection stability between the two, and using the casing 2 to physically protect the wellbore pipe 1.

[0043] Moreover, the connecting seat sleeve 3, the casing 2 and the wellbore pipe 1 enclose a sealing cavity 5. The two ends of the packing 4 are abutted by the reinforcing part and the connecting seat sleeve 3, so as to squeeze the packing 4 to fill and seal the inner wall surface of the sealing cavity 5, preventing the external air and pollution elements from acting on the structure of the wellbore pipe 1 for a long time and causing erosion damage, further realizing the effect of enhancing the protection of the wellbore pipe 1.

[0044] In this technical solution, the wellbore pipe 1 is made of common HDPE material, and the connecting seat sleeve 3 and the casing 2 are preferably but not limited to be made of ABS material.

[0045] Furthermore, it further includes:

[0046] The spacer 6 is an annular structure sleeved and fixedly connected in the sealing cavity 5. A groove 601 is opened on the side of the spacer 6 away from the wellbore pipe 1. A boss 21 is integrally formed and fixedly connected to the inner wall surface of the casing 2. The boss 21 is clamped in the groove 601, and the connecting component is respectively connected to the boss 21 and the spacer 6.

[0047] By sleeving the spacer 6 on the side close to the end of the wellbore pipe 1, the spacer 6 is fixedly connected in the sealing cavity 5, and a groove 601 is opened on the spacer 6, while a boss 21 clamped with the groove 601 is fixedly connected to the inner wall surface of the casing 2, enhancing the connection tightness between the casing 2 and the wellbore pipe 1. Moreover, the connecting component is directly connected to the boss 21 and the spacer 6, forming an elastic trend in the mutually away direction between the boss 21 and the spacer 6, enhancing the clamping stability of the boss 21 and the spacer 6.

[0048] Furthermore, the connecting component includes:

[0049] The connecting ring 7 is fixedly connected to the inner wall at the bottom end of the groove 601. A connecting channel 211 is opened on the end surface of the boss 21 extending into the groove 601. The connecting ring 7 is slidably connected in the connecting channel 211;

[0050] The support spring 8 is wound in the connecting channel 211. The two ends of the support spring 8 are respectively abutted against the connecting ring 7 and the inner wall surface of the connecting channel 211.

[0051] By opening a connecting channel 211 on the boss 21, the connecting ring 7 is limitedly slid in the connecting channel 211, and the supporting spring 8 is used to respectively abut against the connecting ring 7 and the inner wall of the connecting channel 211, thereby abutting against the structure of the wellbore pipe 1 and the casing 2. On the basis of the limited connection between the wellbore pipe 1 and the casing 2, the two maintain an elastic tendency with each other, thereby achieving an improvement in the connection strength between the casing 2 and the wellbore pipe 1, and combined with the abutment with the packing filler 4, efficient sealing is achieved in the sealing chamber 5.

[0052] Furthermore, a gap is provided between the cushion block 6 and the end of the adjacent sealing cavity 5 , and a clamping ring 31 is fixedly connected to the inner wall of the connecting seat sleeve 3 , the clamping ring 31 is used to fill the gap, and the two ends of the cushion block 6 are respectively against the clamping ring 31 and the packing filler 4 .

[0054] Among them, under the action of the supporting spring 8, the two ends of the cushion block 6 are respectively against the connecting seat sleeve 3 and the packing filler 4. Since the packing filler 4 is fixed to the sleeve 2, the elasticity acts on the packing filler 4, and the elastic extension of the packing filler 4 is utilized to fully fill and seal the inner cavity of the sealing cavity 5.

[0055] Furthermore, a flexible sleeve 32 is fixedly connected to the outer peripheral side of the connecting seat sleeve 3, and the flexible sleeve 32 extends axially along the sleeve 2 and covers the outside of the sleeve 2.

[0058] Furthermore, a plurality of inner holes 22 are formed on the outer wall of the sleeve 2 at equal intervals in the circumferential direction, and one end of the inner hole 22 extends into the connecting channel 211 .

[0059] The inner hole 22 of the casing 2 is used to connect the connecting channel 211 with the outside, so that when the connecting ring 7 slides in the connecting channel 211, the gas flows out through the inner hole 22, thereby balancing the air pressure and ensuring the elastic supporting effect of the support spring 8 on the connecting ring 7 and the boss 21 respectively, thereby avoiding the unstable elastic sliding connection between the wellbore pipe 1 and the casing 2 caused by the air pressure supporting the connecting ring 7.

[0060] Furthermore, the strengthening part includes:

[0061] A pair of reinforcing plates 11 are relatively fixed to the outer wall of the wellbore pipe 1, and one end of the reinforcing plate 11 away from the wellbore pipe 1 is in sliding contact with the inner wall surface of the casing 2, and a spacing is provided between the pair of reinforcing plates 11;

[0062] The steel wire rope 12 is wound around the outer circumference of the wellbore pipe 1 , and the steel wire rope 12 abuts against a plurality of reinforcing plates 11 along the wellbore pipe 1 .

[0063] In the present technical solution, each reinforcement part is composed of a pair of reinforcement plates 11 arranged opposite to each other. By fixing a plurality of pairs of reinforcement plates 11 to the outer peripheral side of the wellbore pipe 1 at equal circumferential intervals, the structural strength of the wellbore pipe 1 is improved. A steel wire rope 12 is wound around the outside of the plurality of reinforcement plates 11.

[0064] Furthermore, the reinforcing plate 11 is provided with a plurality of through holes 111 along the axial direction, the plurality of through holes 111 are distributed at equal intervals, a plurality of steel wire ropes 12 are provided corresponding to the through holes 111 in a one-to-one manner, and the same steel wire rope 12 is passed through the plurality of axially corresponding through holes 111 of the wellbore pipe 1.

[0065] Specifically, the steel wire rope 12 is coiled and sleeved outside the wellbore pipe 1 , and the steel wire rope 12 is passed between a plurality of reinforcing plates 11 corresponding to the through holes 111 , so as to enhance the integrity between the reinforcing plates 11 and the steel wire rope 12 .

[0066] Furthermore, a wire clamp 13 is provided between the pair of reinforcing plates 11 . The wire clamp 13 is fixedly connected to the steel wire rope 12 in a one-to-one correspondence. The wire clamp 13 is used to tighten the steel wire rope 12 .

The steel wire rope 12 is fixed by a wire clip 13, so that the steel wire rope 12 presses against the reinforcing plate 11 to tighten the wellbore pipe 1. Then, a casing 2 is sleeved outside the wellbore pipe 1 and the reinforcing plate 11. Cushion blocks 6 are sleeved and fixedly connected to both ends of the wellbore pipe 1, and the bosses 21 on the inner wall surface of the casing 2 are correspondingly clamped with the cushion blocks 6. The connecting ring 7 is inserted into the connecting channel 211, and the elastic supporting force of the supporting spring 8 is maintained. Finally, the connecting seat sleeve 3 and the casing 2 are stably fixed by the clamping protrusions 9 and the clamping grooves 33. The snap ring 31 is filled into the gap between the cushion block 6 and the end of the sealing cavity 5 to realize the stable clamping connection of the connecting seat sleeve 3, the wellbore pipe 1 and the casing 2.
