Description

Technical Field

[0001] This invention relates to the field of pipeline leak prevention technology, and in particular to pipeline leak repair components for water supply systems in oilfield fracturing operations. Background Technology

[0002] In oilfield fracturing operations, a continuous and stable water supply is required. Each fracturing face has a water supply and discharge requirement. Usually, an automated water adjustment system is provided. The water supply system can supply water continuously and achieve the water supply and discharge rate by automatically adjusting the operating status of the pump.

[0003] However, existing water pipes are prone to cracking, loosening, or damage during operation due to pressure and temperature changes or pipe aging, leading to water leakage. Especially under high-pressure water transmission, leakage not only wastes a lot of water resources but also causes insufficient water supply during operation, affecting the normal progress of fracturing operations. Long-term leakage increases the demand for water resources, and in some cases, it may even require additional water sources, increasing operating costs and affecting production efficiency. Leakage causes water to accumulate around the pipes or at the bottom of the equipment, which can easily lead to corrosion of the equipment and pipes. To address this, the present invention proposes a pipe leak repair component for the water supply system in oilfield fracturing operations. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a pipe leak repair component for water supply systems in oilfield fracturing operations. Oilfield fracturing operations have a large demand for water, but traditional water supply systems are prone to problems such as cracks, loose joints, or aging pipes, leading to water leakage. This not only wastes a lot of water resources but may also lead to insufficient water supply, affecting normal operations. This leak repair component, through a precise leak prevention and repair mechanism, can promptly repair leaks when they are detected, effectively preventing water waste, ensuring the normal operation of the water supply system, and avoiding the additional costs of water source scheduling.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pipeline leak repair component for a water supply system in oilfield fracturing operations, including a water supply system base, an automatic regulating pump installed on the water supply system base, several sets of water supply pipes connected to the automatic regulating pump, a flow meter installed on the outer wall of each set of water supply pipes, and a movable regulating mechanism detachably installed on the side wall of the water supply pipe.

[0006] The movable adjustment mechanism is connected to a leak prevention and repair mechanism. The two side walls of the leak prevention and repair mechanism are fitted with extension mechanisms. The leak prevention and repair mechanism slides and adjusts its position on the movable adjustment mechanism. The extension mechanisms are used to increase the coverage area of ​​the leak prevention and repair mechanism.

[0007] The movable adjustment mechanism includes an installation plate mounted on the side wall of the water supply pipe, a side sliding groove opened in the installation plate, a slider slidably connected in the side sliding groove, an upper sliding groove opened above the installation plate and communicating with the side sliding groove, a lead screw mounted on the slider, and a lead screw nut block threadedly connected to the outer wall of the lead screw.

[0008] As a preferred embodiment of the present invention, the top end of the lead screw extends through the upper sliding groove to the outside, and the inner end of the slider is connected to the leak prevention and repair mechanism.

[0009] As a preferred embodiment of the present invention, the outer wall of the filament block is provided with anti-slip texture, the outer diameter of the filament block is set to be greater than the width of the upper sliding groove, and the bottom end of the filament block is provided with a rubber pad.

[0010] As a preferred embodiment of the present invention, the leak prevention and repair mechanism includes a first leak prevention clamping plate installed on the outer wall of the slider, a hinge member disposed on the first leak prevention clamping plate, a second leak prevention clamping plate hinged to the first leak prevention clamping plate via the hinge member, a first mounting seat installed on the top outer wall of the first leak prevention clamping plate, a fastening bolt rod hinged in the first mounting seat, a second mounting seat installed on the top outer wall of the second leak prevention clamping plate, and a nut threadedly connected to the outer wall of the fastening bolt rod.

[0011] As a preferred embodiment of the present invention, the inner walls of the first and second anti-leakage clamping plates are provided with rubber anti-leakage gaskets, and the rubber anti-leakage gaskets are O-shaped after the first and second anti-leakage clamping plates are attached and fixed together.

[0012] As a preferred embodiment of the present invention, an extension mechanism is inserted into the side walls of the first and second leak-proof clamping plates, and the extension mechanism increases the coverage area of ​​the first and second leak-proof clamping plates.

[0013] As a preferred embodiment of the present invention, the extension mechanism includes an insertion groove formed in the first and second leak-proof clamping plates, an insertion rod inserted into the insertion groove, an extended leak-proof plate connected to the insertion rod, a movable cavity formed in the insertion rod, a return spring connected to the inner wall of the movable cavity, a locking block connected to the return spring and slidably connected in the movable cavity, a locking groove formed in the inner wall of the insertion groove, and a pressing plate slidably connected in the locking groove.

[0014] As a preferred embodiment of the present invention, four sets of insertion slots are provided in total, and four sets of insertion rods are provided accordingly. The two sets of insertion rods at the top are provided with movable cavities.

[0015] As a preferred embodiment of the present invention, one end of the reset spring is connected to the inner wall of the movable cavity, and the other end of the reset spring is connected to the bottom end of the locking block.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Oilfield fracturing operations have a large demand for water, while traditional water supply systems are prone to problems such as cracks, loose joints or aging pipes, which can lead to water leakage. This not only wastes a lot of water resources, but may also lead to insufficient water supply and affect normal operations. This leak repair component, through a precise leak prevention and repair mechanism, can repair leaks in a timely manner when they are detected and effectively prevent the waste of water resources, ensuring the normal operation of the water supply system and avoiding the additional costs of water source scheduling.

[0017] 2. This leak-proof component employs a movable adjustment mechanism. Through the cooperation of the lead screw and nut block, the position of the leak-proof and repair mechanism can be precisely adjusted. Workers can move the mechanism to the leak location for effective repair according to actual needs. The repair area can be expanded using an extension mechanism to meet the needs of leaks of different sizes. This flexible design makes leak repair operations more efficient, avoiding the high costs of replacing the entire pipeline or undertaking large-scale repairs.

[0018] 3. The design of the extended mechanism and the leak prevention and repair mechanism not only improves the equipment's adaptability to leaking areas, but also ensures stable operation under high pressure and complex working conditions. The adjustability and flexibility of the leak prevention and repair mechanism enable it to adapt to various pipeline conditions, especially aging and wear, thereby extending the overall service life of the water supply system.

[0028] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0029] Example: Figure 1 - Figure 8 As shown in the figure, this embodiment proposes a pipeline leak repair component for a water supply system in oilfield fracturing operations, including a water supply system base 1, an automatic regulating pump 2 installed on the water supply system base 1, several sets of water supply pipes 3 connected to the automatic regulating pump 2, a flow meter 4 installed on the outer wall of each set of water supply pipes 3, and a movable regulating mechanism 5 detachably installed on the side wall of the water supply pipe 3.

[0030] The movable adjustment mechanism 5 is connected to the leak prevention and repair mechanism 6. The two side walls of the leak prevention and repair mechanism 6 are inserted with the extension mechanism 7. The leak prevention and repair mechanism 6 slides and adjusts its position on the movable adjustment mechanism 5. The extension mechanism 7 is used to increase the coverage area of ​​the leak prevention and repair mechanism 6.

[0031] The movable adjustment mechanism 5 includes a mounting plate 51 installed on the side wall of the water supply pipe 3, a side slide groove 52 opened in the mounting plate 51, a slider 53 slidably connected in the side slide groove 52, an upper slide groove 54 opened above the mounting plate 51 and communicating with the side slide groove 52, a lead screw 55 installed on the slider 53, and a nut block 56 threadedly connected to the outer wall of the lead screw 55.

[0032] Before moving the leak prevention and repair mechanism 6, workers can first rotate the threaded nut 56 upwards to allow it to rotate in conjunction with the threaded rod 55, based on the location of the leak in the water supply pipe 3 or the area requiring repair. This continues until the bottom of the threaded nut 56 separates from the outer wall of the mounting plate 51. At this point, the leak prevention and repair mechanism 6 can be moved, allowing it to slide within the side sliding groove 52 via the slider 53. The slider 53 drives the threaded rod 55 to slide synchronously within the upper sliding groove 54. Once the leak prevention and repair mechanism 6 is moved to the desired position, the threaded nut 56 is tightened downwards, allowing it to move downwards in conjunction with the threaded rod 55. Finally, the bottom of the threaded nut 56 contacts and is fixed to the outer wall of the mounting plate 51, thus fixing the position of the leak prevention and repair mechanism 6. The leak prevention and repair mechanism 6 then repairs leaks in the water supply pipe 3. It should be noted that several sets of leak prevention and repair mechanisms 6 connected to the slider 53 can be configured to slide within the side sliding groove 52, repairing leaks at various locations.

[0033] Specifically, the top of the lead screw 55 extends through the upper sliding groove 54 to the outside, and the inner end of the slider 53 is connected to the leak prevention and repair mechanism 6. This arrangement ensures that when the slider 53 slides in the side sliding groove 52, it can drive the leak prevention and repair mechanism 6 to move synchronously. In this way, the operator can adjust the position of the leak prevention and repair mechanism 6 by moving the slider 53, so that it can be accurately moved to the position of the water supply pipe 3 where leak prevention and repair are needed. The outer wall of the lead screw nut 56 is provided with anti-slip texture, which increases the friction between the operator's hand and the lead screw nut 56. The outer diameter of the lead screw nut 56 is set to be larger than the width of the upper sliding groove 54. The bottom end of the lead screw nut 56 is provided with a rubber pad, which can prevent the lead screw nut 56 from falling into the upper sliding groove 54. When the lead screw nut 56 moves downward and contacts the outer wall of the mounting plate 51, it can be firmly fixed on the mounting plate 51, providing reliable fixed support for the leak prevention and repair mechanism 6.

[0034] The leak prevention and repair mechanism 6 includes a first leak prevention clamping plate 61 installed on the outer wall of the slider 53, a hinge 63 set on the first leak prevention clamping plate 61, a second leak prevention clamping plate 62 hinged to the first leak prevention clamping plate 61 via the hinge 63, a first mounting seat 64 installed on the top outer wall of the first leak prevention clamping plate 61, a fastening bolt rod 65 hinged in the first mounting seat 64, a second mounting seat 66 installed on the top outer wall of the second leak prevention clamping plate 62, and a nut 67 threadedly connected to the outer wall of the fastening bolt rod 65.

[0035] Workers used the leak prevention and repair mechanism 6 to repair leaks in the water supply pipe 3. Specifically, the first leak prevention clamping plate 61 and the second leak prevention clamping plate 62 were initially in the following state: Figure 5As shown, the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are in the open state. After being moved to a suitable position by the moving adjustment mechanism 5, the second leak-proof clamping plate 62 is rotated so that it fits against the first leak-proof clamping plate 61. At this time, the fastening bolt rod 65 is rotated so that it rotates within the first mounting base 64. The nut 67 drives the fastening bolt rod 65 to engage with the second mounting base 66. Then, the nut 67 is rotated inward so that it rotates inward on the fastening bolt rod 65. Finally, the inner end of the nut 67 contacts the outer wall of the second mounting base 66 to form a fixation. Finally, the positions of the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are tightened and fixed, so that the inner walls of the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are tightly fitted against the outer wall of the water supply pipe 3 to form a seal to prevent leakage. Similarly, the nut 67 is turned outward to release the fixation of the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 and restore the open state.

[0036] Specifically, the inner walls of the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are provided with rubber leak-proof gaskets. The rubber leak-proof gaskets have good flexibility and sealing performance. After the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are attached and fixed, the rubber leak-proof gaskets are O-shaped. The O-shaped rubber leak-proof gaskets can wrap the water supply pipe 3 in all directions to form a closed sealing space. The two side walls of the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 are inserted with extension mechanisms 7. The extension mechanisms 7 increase the coverage area of ​​the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62. In the actual oilfield fracturing operation water supply system, the location and range of water leakage in the water supply pipe 3 are different. When the area that needs to be prevented and repaired is large, the coverage area of ​​the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62 alone may not be able to meet the needs. By setting up the extension mechanism 7, staff can flexibly increase the coverage area for leak prevention and repair according to the actual situation, thereby better adapting to leak areas of different sizes and improving the versatility and applicability of the leak repair component.

[0037] The extension mechanism 7 includes an insertion groove 71 formed in the first leak-proof clamping plate 61 and the second leak-proof clamping plate 62, an insertion rod 73 inserted into the insertion groove 71, an extended leak-proof plate 72 connected to the insertion rod 73, a movable cavity 74 provided in the insertion rod 73, a return spring 75 connected to the inner wall of the movable cavity 74, a locking block 76 connected to the return spring 75 and slidably connected in the movable cavity 74, a locking groove 77 formed in the inner wall of the insertion groove 71, and a pressing plate 78 slidably connected in the locking groove 77.

[0038] If the area requiring leak prevention and repair for water supply pipe 3 is large, the worker can use the extended leak-proof plate 72 to connect the plug rod 73 to the plug groove 71. During the connection process between the two sets of plug rods 73 at the top and the plug groove 71, the inner wall of the plug groove 71 presses the locking block 76 downward, causing the locking block 76 to deform downward by pressing the return spring 75. At this time, the locking block 76 is pressed into the movable cavity 74 and slides. After the plug rod 73 is fully inserted into the plug groove 71, the locking block 76 moves to the position of the locking groove 77, and the elasticity of the return spring 75 itself... The generated restoring force pushes the locking block 76 to return to its original position. The locking block 76 is popped up and engages with the locking slot 77 to form a fixed position. The coverage area is increased by inserting the extended leak-proof plates 72 on both sides, thereby matching a larger leak-proof and leak-repairing water supply pipe 3. Similarly, when it is necessary to disassemble the extended leak-proof plate 72, simply press down on the pressing plate 78, so that the pressing plate 78 squeezes the locking block 76 to move downward. The locking block 76 squeezes the reset spring 75 to deform. After the locking block 76 is squeezed into the movable cavity 74, pull the extended leak-proof plate 72 outward to pull out the plug rod 73 to complete the disassembly.

[0039] It is worth noting that there are four sets of insertion slots 71, and four sets of insertion rods 73 are correspondingly arranged. The two upper sets of insertion rods 73 have movable cavities 74. Through multiple sets of insertion and engagement, the force can be distributed, preventing the extended leak-proof plate 72 from loosening or falling off during use, thus ensuring the reliability and stability of the extension mechanism 7. One end of the return spring 75 is connected to the inner wall of the movable cavity 74, and the other end is connected to the bottom end of the locking block 76. The movable cavity 74, the return spring 75, and the locking block 76 together constitute a core locking mechanism. When the insertion rods 73 of the extended leak-proof plate 72 are inserted into the insertion slots 71... When the plug 76 is fully inserted into the insertion slot 71, the locking block 76 is pressed into the movable cavity 74, and the return spring 75 is compressed and deformed. When the plug rod 73 is fully inserted into the insertion slot 71, the locking block 76 moves to the slot 77 position. The elastic restoring force of the return spring 75 will push the locking block 76 to spring up and engage with the slot 77, thereby fixing the extended leak-proof plate 72. This design makes the installation and removal of the extended leak-proof plate 72 very convenient, while ensuring the firmness of its connection. When it is necessary to remove the extended leak-proof plate 72, simply press the pressing plate 78 to retract the locking block 76 into the movable cavity 74, and the plug rod 73 can be easily pulled out to complete the removal operation.
