[0002] After horizontal wells in oil and gas fields are put into production, low temperatures often cause blockages in the horizontal section, affecting oil and gas production or even halting production. Therefore, heating cables are generally used, and due to their long length, the cables are often connected in sections.

[0003] A search revealed a prior art device for connecting heating cables in the horizontal section of an oil and gas well, with patent publication number CN217641839U. The specification states that the device ensures the heating cable is smoothly lowered into the horizontal section, meets the electrical connection reliability and electrical insulation and waterproof sealing requirements of the cables between the horizontal and vertical sections, ensures that heating of the entire well section achieves the purpose of safe production, and ensures normal production of the oil and gas well.

[0004] However, in actual use, the cable joints are still connected with insulating tape. This requires carrying a roll of tape and wrapping it around the cable joint multiple times, which is time-consuming and labor-intensive. Furthermore, after prolonged use, the tape is easily loosened and detached due to external environmental factors, resulting in low economic efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a heating cable connection device for the horizontal section of oil and gas wells, so as to solve the problem that the existing technology uses insulating tape to wrap the cable connection point in multiple turns, which is time-consuming and labor-intensive, and is easily loosened and detached due to the influence of the external environment after long-term use, thus resulting in low economic efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heating cable connection device for a horizontal section of an oil and gas well, comprising two cable bodies, a connecting ring sleeved between the two cable bodies, the connecting ring being a hinged design, a limiting groove being formed at one end of the connecting ring, two slots being formed inside the limiting groove, a locking block being locked inside the slot, a limiting block being slidably connected to the outside of the locking block, the limiting block being fixedly connected to the other end of the connecting ring, the limiting block being slidably connected inside the limiting groove, a receiving groove being formed on the inner side of the connecting ring, a plurality of clamping blocks being slidably connected inside the receiving groove, the clamping blocks being in contact with the cable body.

[0007] The connecting ring has multiple placement slots inside, and an elastic element two is fixedly connected to the inner wall of the placement slot. A connecting piece is fixedly connected to the other end of the elastic element two. Two connecting posts are fixedly connected to the end of the connecting piece away from the elastic element two, and the other end of the connecting posts is fixedly connected to the clamping block.

[0008] The limiting block has two mounting slots inside. The end of the locking block away from the slot is fixedly connected to a mounting piece. The end of the mounting piece away from the locking block is fixedly connected to a pull rope. The end of the pull rope away from the mounting piece is fixedly connected to a pull block. An elastic element is sleeved on the outside of the pull rope.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a heating cable connection device for a horizontal section of an oil and gas well, comprising a connecting ring 2 sleeved between two cable bodies 1. The connecting ring 2 is hinged, allowing it to be opened and closed. One end of the connecting ring 2 has a limiting groove 3, and two slots 4 are provided inside the limiting groove 3. A locking block 5 is engaged inside the slot 4. A limiting block 17 is slidably connected to the outside of the locking block 5, so that the limiting block 17 is limited inside the limiting groove 3. The limiting block 17 is fixedly connected to the other end of the connecting ring 2 and slidably connected inside the limiting groove 3. The limiting groove 3 limits the limiting block 17, allowing the connecting ring 2 to be stably installed on the cable body 1. A receiving groove 16 is provided on the inner side of the connecting ring 2, and multiple clamping blocks 11 are slidably connected inside the receiving groove 16. The clamping blocks 11 are in contact with the cable body 1. The clamping blocks 11 are made of insulating material and have multiple anti-slip protrusions on their inner side, so that the cable body 1 is stably limited and sealed.

[0024] When connecting cable bodies 1, the two cable bodies 1 are joined together, and then the connecting ring 2 is fitted onto the cable body 1. The two locking blocks 5 are moved towards each other, allowing them to disengage from the slot 4 and enter the limiting block 17. The two ends of the connecting ring 2 are then brought together, allowing the limiting block 17 to slide into the limiting groove 3. The two locking blocks 5 are then moved away from each other, engaging with the slot 4. At this point, the clamping block 11 is tightly fitted to the cable body 1, thus limiting and sealing the cable body 1. This not only improves the stability of the cable connection but also makes the connection more convenient, reducing labor costs and improving economic efficiency.

[0025] Example 2: Based on Example 1, in order to improve the limiting and sealing effect on the cable body 1, multiple placement grooves 12 are provided inside the connecting ring 2. An elastic element 2 15 is fixedly connected to the inner wall of the placement groove 12. A connecting piece 14 is fixedly connected to the other end of the elastic element 2 15. The connecting piece 14 is slidably connected inside the placement groove 12. The placement groove 12 limits the connecting piece 14, allowing the connecting piece 14 to slide smoothly. Two connecting posts 13 are fixedly connected to the end of the connecting piece 14 away from the elastic element 2 15. The connecting posts 13 are slidably connected inside the placement groove 12. The placement groove 12 limits the connecting posts 13, allowing the connecting posts 13 to slide smoothly. The other end of the connecting posts 13 is fixedly connected to the clamping block 11.

[0026] When the clamping block 11 is in contact with the cable body 1, the clamping block 11 will move outward, so that the clamping block 11 can push the connecting post 13 to move outward, and then the connecting post 13 can push the connecting piece 14 to squeeze the elastic element 15 to deform, so that the elastic element 15 can perform a reset movement, and then the elastic element 15 can push the connecting post 13 to move inward, so that the connecting post 13 can push the clamping block 11 to fit tightly with the cable body 1.

[0027] Example 3: Based on Example 2, to facilitate the pulling of the locking block 5, two mounting grooves 6 are provided inside the limiting block 17. The locking block 5 is slidably connected inside the mounting grooves 6, and the mounting grooves 6 limit the locking block 5, allowing it to slide smoothly. A mounting piece 7 is fixedly connected to the end of the locking block 5 away from the locking groove 4. The mounting piece 7 is slidably connected inside the mounting groove 6, and the mounting groove 6 limits the mounting piece 7, allowing it to slide smoothly. The end of the mounting piece 7 away from the locking block 5... A pull rope 8 is fixedly connected to one end of the pull rope 8, which is slidably connected inside the mounting groove 6. The mounting groove 6 limits the pull rope 8 so that it will not deviate when sliding. A pull block 10 is fixedly connected to the end of the pull rope 8 away from the mounting plate 7. The pull block 10 is slidably connected inside the front end of the limiting block 17. The limiting block 17 provides installation space for the pull block 10. An elastic element 9 is sleeved on the outside of the pull rope 8. One end of the elastic element 9 is fixedly connected to the inner wall of the mounting groove 6, and the other end of the elastic element 9 is fixedly connected to the mounting plate 7.

[0028] When the locking block 5 needs to be pulled, the pulling block 10 is pulled outward, which in turn pulls the pulling rope 8 outward. This causes the pulling block 10 to cause the mounting plate 7 to compress the elastic element 9, resulting in deformation, and the locking block 5 is driven into the interior of the mounting groove 6. Conversely, by releasing the pulling block 10, the elastic element 9 is reset, which pushes the mounting plate 7 outward. This causes the mounting plate 7 to push the locking block 5 into the interior of the groove 4, and the clamping block 11 to fit against the cable body 1.

[0029] The working process of this utility model is as follows:

[0030] When the cable body 1 needs to be connected, pulling the pull block 10 outward causes the pull rope 8 to move outward, which in turn causes the mounting plate 7 to deform by squeezing the elastic element 9, and moves the locking block 5 into the mounting groove 6. At this time, the connecting ring 2 is fitted onto the cable body 1, so that the two ends of the connecting ring 2 are in contact, and the limiting block 17 slides into the limiting groove 3. Then, by releasing the pull block 10, the elastic element 9 can perform a reset movement, which in turn pushes the mounting plate 7 outward, thus allowing the mounting plate 7 to... The push block 5 engages with the inside of the slot 4. During this process, the clamping block 11 moves outward, which pushes the connecting post 13 outward. This causes the connecting post 13 to push the connecting piece 14 to compress the elastic element 15, causing it to deform. The elastic element 15 then returns to its original position, pushing the connecting post 13 inward. This allows the connecting post 13 to push the clamping block 11 into close contact with the cable body 1. This not only improves the stability of the cable connection but also makes the connection more convenient, thereby reducing labor costs and improving the economic efficiency of use.
