Description

Technical Field

[0001] The utility model relates to the technical field of oilfield development, in particular to a cable protection bypass pipe that can be continuously docked. Background Technique

[0002] During the operation of oil well tubing, power cables and signal cables need to be introduced from the wellhead into the well to be docked with corresponding equipment.

[0003] However, the traditional connection method is to directly connect the cables to the equipment by bundling them outside the pipe. This connection method lacks a fixing mechanism for the cables and the cables are exposed outside the tubing, which makes the cables prone to shaking and rubbing against the tubing, affecting the service life of the cables and making them extremely vulnerable to damage, thus affecting work efficiency. Summary of the Utility Model

[0004] Based on the existing technical problems in oilfield development, the utility model proposes a cable protection bypass pipe that can be continuously docked.

[0005] The cable protection bypass pipe that can be continuously docked proposed by the utility model includes a bypass pipe. A plurality of cables are detachably fixed around the outer wall of the bypass pipe. A plurality of installation grooves are formed in the outer wall of the bypass pipe, and a plurality of locking mechanisms are installed inside each installation groove. Four connecting columns are equidistantly fixed at one end of the bypass pipe, and a fixed chuck is fixed at the end of the connecting column. A fixed nut is sleeved on the outer wall of the connecting column; at the other end of the bypass pipe, fixed screws adapted to the four fixed nuts are equidistantly fixed, and a first fixed card slot adapted to the four fixed chucks is formed in the middle of each fixed screw.

[0006] Preferably, a ventilation groove is formed in the middle of the bypass pipe, a plurality of ventilation holes are formed inside each installation groove, and each ventilation hole penetrates into the ventilation groove.

[0007] Through the above technical solution, the through setting of the ventilation groove and the ventilation holes enables the cables to enhance heat dissipation when fixed inside the installation groove, preventing the cables from overheating, thereby enabling the cables to have a longer service life.

[0008] Preferably, the locking mechanism includes a first protective ring fixed inside the installation groove, and the other end of the first protective ring is fixedly connected with a second protective ring in a clamping manner. A first annular groove is formed in the middle of one side of the first protective ring, and second fixed clamping grooves are formed in the middle of both sides of the first annular groove at the end of the first protective ring. An activity groove is formed inside the first protective ring on both sides of each second fixed clamping groove, and a first sliding groove communicating with the activity groove is formed at the end of the first protective ring on both sides of each second fixed clamping groove. A second sliding groove communicating with the second fixed clamping groove is formed in the middle of each activity groove. Two first springs are fixedly arranged on one side of each activity groove away from the second sliding groove, and an activity plate is slidably fixed on one side of each activity groove close to the second sliding groove. The side of the activity plate away from the second sliding groove is fixedly connected with the first spring. A sliding rod adapted to the first sliding groove is fixed at one end of the activity plate close to the second protective ring, and a first clamping block adapted to the second sliding groove is fixedly arranged on the other side of the first spring.

[0009] Through the above technical solution, a first spring and an activity plate are installed inside the activity groove, a first clamping block is arranged on the other side of the activity plate, and the first clamping block can slide into the second fixed clamping groove. A sliding rod is fixed on the top of the activity plate. Therefore, by sliding the sliding rod, the first clamping block can slide into the activity groove or the second fixed clamping groove, so as to facilitate the fixation of the second protective ring, and thus facilitate the fixation and disassembly of the cable.

[0010] Preferably, a second annular groove is formed in the middle of one side of the second protective ring, a fixed groove is formed in the middle of the second annular groove, two second springs are fixedly arranged inside the fixed groove, and an annular abutting block is fixedly arranged at the other end of the second spring. Second clamping blocks are fixedly arranged on both outer sides of the second protective ring, and a third fixed clamping groove adapted to the first clamping block is formed on the side surface of the second clamping block away from the second protective ring.

[0011] Through the above technical solution, the mutual cooperation of the arranged second spring and the annular abutting block enables the cable to be abutted, so as to fix cables of different sizes, and the practicability is better. The third fixed clamping groove arranged on the second clamping block enables the first clamping block to be mutually clamped with the third fixed clamping groove when the second clamping block is inserted into the second fixed clamping groove, so as to facilitate the better fixation of the second protective ring and the first protective ring.

[0012] Preferably, the bottom of the second clamping block is triangular, the first clamping block is trapezoidal with a right angle, and one side surface of the second clamping block is adapted to the inclined side surface of the first clamping block.

[0013] Through the above technical solution, when the second card block is inserted into the second fixed card slot, the bottom of the second card block and the oblique side surface of the first card block contact each other, so that when pressing downward, the second card block can easily enter the movable slot, and the second card block can be easily inserted into the bottom of the second fixed card slot without sliding the slide rod. When the second card block reaches the bottom of the second fixed card slot, the first card block rebounds into the third fixed card slot due to the elasticity of the first spring, thereby facilitating the fixation of the first guard ring and the second guard ring, thereby facilitating the installation and fixation of the cable.

[0014] Preferably, protective rubber is installed inside the first annular groove and the second annular groove, and protective rubber is installed on the side of the annular stop away from the second spring.

[0015] Through the above technical solution, protective rubber is installed on the first annular groove, the second annular groove and the annular stop block, so that the cable is not easily damaged when it is installed, making the cable fixation safer.

[0016] The beneficial effects of the present invention are:

[0017] 1. By opening multiple installation grooves on the outer wall of the bypass pipe, the cable is fixed inside the installation groove, thereby avoiding direct friction between the cable and the oil pipe, thereby protecting the cable and extending the service life of the cable.

[0018] 2. By setting a connecting column, a fixing clamp, a fixing nut, a fixing screw and a first fixing groove, when multiple bypass pipes are connected and fixed to each other, the fixing clamp on the first bypass pipe is inserted into the first fixing groove on the second bypass pipe, and then the fixing nut is rotated to thread the fixing nut and the outer wall of the fixing screw, thereby facilitating the connection of multiple bypass pipes.

[0019] 3. By setting up a locking mechanism, and the locking mechanism is fixed by clamping the first guard ring and the second guard ring, it is convenient to install and remove the cable. A second spring and an annular block are also provided inside the locking mechanism, so that the annular block cooperates with the first annular groove, which can fix cables of different sizes, making it more practical.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Referring to Figures 1-4 , a continuously dockable cable protection bypass pipe includes a bypass pipe 1. A plurality of cables 2 are detachably fixed around the outer wall of the bypass pipe 1. A plurality of installation grooves 101 are opened on the outer wall of the bypass pipe 1, and a plurality of locking mechanisms 3 are installed inside each installation groove 101. Four connecting columns 102 are equidistantly fixed at one end of the bypass pipe 1, and a fixed chuck 103 is fixed at the end of the connecting column 102. A fixed nut 104 is sleeved on the outer wall of the connecting column 102; Four fixed screws 105 adapted to the four fixed nuts 104 are equidistantly fixed at the other end of the bypass pipe 1, and a first fixed card slot 106 adapted to the four fixed chucks 103 is opened in the middle of each fixed screw 105; A ventilation groove 108 is opened in the middle of the bypass pipe 1. A plurality of ventilation holes 107 are opened inside each installation groove 101, and each ventilation hole 107 penetrates into the ventilation groove 108.

[0027] Through the through setting of the ventilation groove 108 and the ventilation holes 107, when the cable 2 is fixed inside the installation groove 101 for work, the heat dissipation of the cable 2 can be enhanced, preventing the cable 2 from overheating, so that the service life of the cable 2 can be longer.

[0028] Furthermore, referring toFigure 2 and Figure 4 The locking mechanism 3 includes a first protective ring 31 fixed inside the installation groove 101. The other end of the first protective ring 31 is clamped and fixed with a second protective ring 32. A first annular groove 3101 is formed in the middle of one side of the first protective ring 31. Second fixed clamping grooves 3102 are formed in the middle of both sides of the first annular groove 3101 at the end of the first protective ring 31. Moving grooves 3104 are formed inside the first protective ring 31 on both sides of each second fixed clamping groove 3102. First sliding grooves 3103 communicating with the moving grooves 3104 are formed at the ends of the first protective ring 31 on both sides of each second fixed clamping groove 3102. Second sliding grooves 3108 penetrating through to the second fixed clamping grooves 3102 are formed in the middle of each moving groove 3104. Two first springs 3106 are fixedly arranged on the side of each moving groove 3104 away from the second sliding groove 3108. A moving plate 3105 is slidably fixed on the side of each moving groove 3104 close to the second sliding groove 3108. The side of the moving plate 3105 away from the second sliding groove 3108 is fixedly connected with the first spring 3106. A sliding rod 3107 adapted to the first sliding groove 3103 is fixed at one end of the moving plate 3105 close to the second protective ring 32. A first clamping block 3109 adapted to the second sliding groove 3108 is fixedly arranged on the other side of the first spring 3106.

[0029] The first spring 3106 and the moving plate 3105 are installed inside the moving groove 3104. The first clamping block 3109 is arranged on the other side of the moving plate 3105. The first clamping block 3109 can slide into the second fixed clamping groove 3102. A sliding rod 3107 is fixed on the top of the moving plate 3105. By sliding the sliding rod 3107, the first clamping block 3109 can slide into the moving groove 3104 or the second fixed clamping groove 3102, so as to facilitate the fixing of the second protective ring 32 and the fixing and disassembly of the cable 2.

[0030] Further, referring to Figure 4 A second annular groove 3203 is formed in the middle of one side of the second protective ring 32. A fixing groove 3202 is formed in the middle of the second annular groove 3203. Two second springs 3204 are fixedly arranged inside the fixing groove 3202. The other ends of the second springs 3204 are fixedly provided with annular abutting blocks 3205. Second clamping blocks 3201 are fixedly arranged on both outer sides of the second protective ring 32. Third fixed clamping grooves 3206 adapted to the first clamping block 3109 are formed on the side surfaces of the second clamping blocks 3201 away from the second protective ring 32.

[0031] Through the mutual cooperation of the second spring 3204 and the annular abutting block 3205, it is possible to abut against the cable 2, so that cables 2 of different sizes can be fixed, which has better practicability. Moreover, setting the third fixing slot 3206 on the second clamping block 3201 enables the first clamping block 3109 to be engaged with the third fixing slot 3206 after the second clamping block 3201 is inserted into the second fixing slot 3102, thus facilitating the better fixing of the second protective ring 32 and the first protective ring 31.

[0032] Furthermore, referring to Figure 4 , the bottom of the second clamping block 3201 is triangular in shape, the first clamping block 3109 is trapezoidal in shape with a right angle, and one side surface of the second clamping block 3201 is adapted to the inclined side surface of the first clamping block 3109.

[0033] When the second clamping block 3201 is inserted into the second fixing slot 3102, the bottom of the second clamping block 3201 abuts against the inclined side surface of the first clamping block 3109. Therefore, when pressing down, the second clamping block 3201 can easily enter the movable slot 3104 without sliding the sliding rod 3107, and the second clamping block 3201 can be easily inserted to the bottom of the second fixing slot 3102. When the second clamping block 3201 reaches the bottom of the second fixing slot 3102, due to the elasticity of the first spring 3106, the first clamping block 3109 rebounds and enters the third fixing slot 3206, thus facilitating the fixing of the first protective ring 31 and the second protective ring 32, and facilitating the installation and fixing of the cable 2.

[0034] Furthermore, protective rubber is installed inside both the first annular groove 3101 and the second annular groove 3203, and protective rubber is installed on the side of the annular abutting block 3205 away from the second spring 3204.

[0035] By installing protective rubber on the first annular groove 3101, the second annular groove 3203 and the annular abutting block 3205, it is possible to prevent the cable 2 from being damaged during the installation of the cable 2, making the fixing of the cable 2 safer.

[0036] Working principle: When in use, if the oil well is very deep and multiple bypass pipes 1 are required, insert the fixed chuck 103 on the first bypass pipe 1 into the first fixed card slot 106 on the second bypass pipe 1, and then rotate the fixed nut 104 on the first one to be threadedly fixed with the fixed screw rod 105 on the second one, and so on, so as to facilitate the fixation of multiple bypass pipes 1; then when it is necessary to fix the cable 2, place each cable 2 on the first protective ring 31 inside each installation groove 101 respectively, and then press the second clamping block 3201 on the second protective ring 32 into the second fixed card slot 3102 toward the inside of the second fixed card slot 3102, so that the second protective ring 32 is fixed on the top of the first protective ring 31, so that the first protective ring 31 and the second protective ring 32 fix the cable 2, and when disassembly is required, slide the sliding rod 3107 so that the first clamping block 3109 enters the movable groove 3104, so that the second clamping block 3201 can be conveniently pulled out of the second fixed card slot 3102 to the outside of the second fixed card slot 3102, so as to facilitate the disassembly of the cable 2.

[0037] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
