DETAILED DESCRIPTION

[0027] The utility model will be further described below in combination with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0028] Example 1:

[0029] As Figures 1-5 shown, the tubing coupling of the oilfield water distribution system provided by the utility model comprises: a tube body 1, connection threads 2 are arranged at both ends of the tube body 1, the connection threads 2 are threadedly matched with the end part of a tubing 14, so that the tube body 1 can be threadedly connected with the tubing 14, two tubings 14 are respectively connected at both ends of the tube body 1, a plurality of cable fixing mechanisms 3 are arranged in the tube body 1, the plurality of cable fixing mechanisms 3 can be uniformly distributed ( Figure 2 ) or concentratedly distributed ( Figure 3The cable fixing mechanism 3, arranged in a manner similar to that in the pipe body 1, includes a support plate 4 fixed to the inner wall of the pipe body 1. A groove 5 is formed on the inner side of the support plate 4, allowing the cable of the water distributor working cylinder to be embedded in the groove 5. Fixing components 6 are provided at both ends of the support plate 4, which can then fix the cable within the groove 5. In use, oil pipes are connected via this device. The cable of the water distributor working cylinder is straightened and embedded into the groove 5, and then the fixing components 6 are used to fix the cable within the groove. This ensures the cable of the water distributor working cylinder is fixed within the oil pipe, preventing movement when subjected to oil and water erosion, thus improving cable safety. It is worth noting that this device is primarily used on oil pipes within sand-proof sections, replacing traditional oil pipe couplings to facilitate cable passage and provide cable fixing and protection.

[0030] By setting up a pipe body 1, a connecting thread 2, and a cable fixing mechanism 3 including a support plate 4, a slot 5, and a fixing component 6, it can play the role of passing through and fixing and protecting the cable, and can replace the traditional oil pipe coupling, thus improving the safety of the cable during use.

[0031] Example 2:

[0032] like Figures 2-3 As shown, multiple cable fixing mechanisms 3 are arranged in a circular array, and the bottom of the slot 5 matches the inner wall of the oil pipe 14, so that the cable can smoothly enter the slot 5 in the oil pipe 14, the cable path is straighter, and the length of the cable in the oil pipe is minimized, which can help save the cable length and reduce costs. In addition, because the cable transitions smoothly in the oil pipe, it is not easy to fluctuate, so the cable can fit against the inner wall of the oil pipe and obtain a certain support, making the cable more stable.

[0033] By setting the slot 5 to match the oil pipe, it is possible to reduce costs and improve cable stability.

[0034] Example 3:

[0035] like Figure 5 As shown, the fixing component 6 includes a connecting ear 7, a clamping member 8, a pad 9, and a bolt 10. The connecting ear 7 is located on both sides of the slot 5 and is integrally formed with the support plate 4. In use, after the cable is embedded in the slot 5, the clamping member 8 is pressed against the side of the cable, and the bolt 10 is used to pass through the pad 9, the clamping member 8, and the connecting ear 7 in sequence and tighten the nut, thereby fixing the cable in the slot 5.

[0036] The cable can be easily secured by the fixing assembly 6, which includes a connecting ear 7, a clamping part 8, a pad 9, and a bolt 10.

[0037] Example 4:

[0038] like Figure 5As shown, in this embodiment, a positioning groove 11 is provided on the connecting ear 7, and an integrally formed positioning post 12 is provided on the pad 9. When in use, the positioning post 12 is inserted into the positioning groove 11, so that the pad 9 will not rotate when the bolt 10 is rotated.

[0039] By setting the positioning groove 11 and the positioning post 12, the pad 9 can be easily limited.

[0040] Example 5:

[0041] like Figure 5 As shown, integrally formed pressure ears 13 are provided at both ends of the clamping member 8. In use, the bolt 10 passes through the pressure ears 13 to fix the clamping member 8.

[0042] By providing integrally formed pressure ears 13 at both ends of the clamping member 8, the clamping member 8 can be easily fixed.

[0043] Example 6:

[0044] In this embodiment, the clamping member 8 is made of rubber. When in use, the clamping member 8 is pressed tightly against the cable. The rubber clamping member 8 itself can deform to a certain extent, which makes it less likely to cause cable damage due to excessive fixing force.

[0045] By setting up a rubber clamping part 8, the cable can be protected, making it less likely to be damaged while being fixed, thus improving the safety of the cable.

[0046] Working Principle: In use, oil pipes are connected via this device. The cable of the water distributor's working cylinder is straightened and embedded into the slot 5. The fixing component 6 then secures the cable within the slot, thus fixing the cable of the water distributor's working cylinder within the oil pipe. This prevents the cable from moving easily when subjected to oil and water erosion, thereby improving cable safety. It is worth noting that this device is primarily used for oil pipe connections within sand control sections, replacing traditional oil pipe couplings to facilitate cable passage and provide cable protection.
