Description

Technical Field

[0001] This utility model relates to the field of jet dewaxing technology for oil pipelines, specifically a high-pressure water jet dewaxing device for oil pipelines. Background Technology

[0002] The high-pressure water jet dewaxing equipment for oil pipelines is a highly efficient cleaning device designed specifically for removing paraffin deposits inside oil pipelines. Its core principle is to use the powerful impact of high-pressure water jets to peel off and flush away impurities such as wax, oil, and scale adhering to the inner wall of the pipeline, thereby restoring the pipeline's flow capacity and ensuring the efficiency and safety of oil transportation. Currently, the commonly used wax removal methods in the industry have obvious limitations: although chemical wax dissolving technology can deal with some complex pipe structures, it requires the addition of chemical agents, which is not only costly, but also easy to corrode the pipe material; and if the waste liquid is not properly treated, it will cause environmental pollution, which does not meet the requirements of green production. Traditional mechanical wax removal equipment is difficult to adapt to pipes of different lengths, and the jet coverage of the flushing head is limited, resulting in inconsistent wax removal efficiency. For example, a multi-functional oilfield wax removal device with application number CN202222189940.2 uses a high-pressure nozzle to spray hot liquid, a serrated scraper to peel off the wax, an annular scraper for secondary cleaning, and a suction pump to guide the wax debris into a transfer box through a suction pipe and discharge it through a wax discharge pipe. This device has a complex structure, which is not only not conducive to daily maintenance, but also lacks expansion capabilities and has a relatively limited cleaning distance. Based on this, this solution proposes "a high-pressure water jet dewaxing device for oil pipelines" to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a high-pressure water jet dewaxing device for oil pipelines, in order to solve the problems mentioned in the background art, such as the complex structure of existing equipment on the market, which is not only not conducive to daily maintenance, but also lacks expansion performance and has a relatively limited cleaning distance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure water jet dewaxing device for oil pipelines, comprising a bearing pipe, a connecting pipe, a tail pipe, a flushing head, and a second water outlet; A flow-blocking mechanism is provided on the right side of the bearing pipe. The flow-blocking mechanism includes a protective plate, a first handle, a first gripper, a second gripper, a first connecting rod, a second handle, a second connecting rod, and a spring. The protective plate is installed on the side of the first handle, the first gripper and the second gripper are installed on the side of the first handle, the first connecting rod and the second connecting rod are installed above the first gripper and the second gripper, the spring is installed above the first handle, and the second handle is installed above the spring.

[0005] As a preferred technical solution of this utility model, the left side of the bearing tube is fixedly connected to the connection port, the connection port is a hexagonal structure, and the left side of the connection port has an internal thread structure. The top of the bearing tube is fixedly connected to the bearing handle, the bearing handle is a figure-eight structure, and there are two bearing handles symmetrically distributed. Using the above technical solution, the hexagonal connector on the left side of the carrier tube has an internal thread. The hexagonal structure facilitates fastening with tools, ensuring a stable connection with the external high-pressure water source, reducing the risk of leakage, and ensuring stable water pressure during the wax removal process. The two symmetrical figure-eight shaped carrier handles above the carrier tube are ergonomically designed to disperse the reaction force generated by the high-pressure water flow, making the operator's grip more stable, reducing hand fatigue, improving the accuracy of operation, and ensuring that the rinsing head is accurately aimed at the wax-stained area.

[0006] As a preferred technical solution of this utility model, the right side of the bearing pipe has a threaded structure, and the right side of the bearing pipe is threadedly connected to the connecting pipe. The right side of the connecting pipe is threadedly connected to the tail pipe, and the bearing pipe, the connecting pipe, and the tail pipe have the same threaded interface structure. By adopting the above technical solution, the bearing pipe, connecting pipe, and tail pipe are connected through threaded interfaces of the same structure, realizing modular combination. The number of connecting pipes can be flexibly increased or decreased according to the actual length of the oil pipeline, thereby adapting to the wax removal needs of pipelines of different lengths and enhancing the applicability of the equipment. The threaded connection method also facilitates the disassembly and maintenance of each component. When a component is damaged, it can be replaced individually without scrapping the entire equipment, reducing maintenance costs and time costs.

[0007] As a preferred technical solution of this utility model, the tail tube is rotatably connected to the flushing head on the right side. The outer side of the flushing head has a three-lobed spiral structure. Three first water outlet holes are evenly opened on the side of the flushing head, and the first water outlet holes are triangularly distributed facing the rear. A second water outlet hole is opened at the center of the right side of the flushing head. A fixed guide tube is embedded in the flushing head. Using the above technical solution, the flushing head rotatably connected to the right side of the tailpipe has a three-lobed spiral structure on its outer side that can mechanically scrape away hard wax scale on the inner wall of the pipe when it rotates. Combined with the three triangularly distributed and rearward-facing first water outlets on the side, it can form a uniform circumferential high-pressure water jet. The reaction force of the water flow can also drive the flushing head to rotate autonomously, expanding the wax removal coverage area. The second water outlet in the center of the right side of the flushing head cooperates with the first water outlet to form a three-dimensional flushing in the axial and circumferential directions, ensuring that there are no dead corners for wax removal on the inner wall of the pipe. The built-in guide tube can stably guide the high-pressure water flow, reduce pressure loss, ensure uniform jet pressure in each water outlet, and improve the consistency of the wax removal effect.

[0008] As a preferred technical solution of this utility model, the bearing tube is configured at the opposite position of the protective plate, the protective plate is rotatably connected to the first handle, the first gripper is rotatably connected to the side of the first handle, the first gripper is rotatably connected to the second gripper on the side of the first gripper, and the first gripper and the second gripper are symmetrically distributed in two sets at both ends of the first handle. The outer sides of the first gripper and the second gripper are rotatably connected to the first connecting rod and the second connecting rod respectively. The top of the first connecting rod and the second connecting rod is rotatably connected to the second handle. A pair of springs are fixedly connected between the first handle and the second handle. The above technical solution features a support pipe and a protective plate facing each other, with the protective plate rotatably connected to the first handle. The position can be adjusted according to the pipe diameter and operating angle, ensuring a tight fit against the outer wall of the pipe and effectively blocking high-pressure water jets and wax shavings, thus protecting operator safety. Two sets of symmetrically distributed first and second grippers form a stable clamping mechanism from both sides of the pipe. Combined with the linkage structure of the first and second connecting rods and the second handle, squeezing the second handle compresses the spring and opens the grippers. Releasing the grippers resets the spring, automatically clamping the pipe. This convenient operation requires no additional tools to secure the equipment, preventing displacement due to reaction forces during flushing and improving operational stability and safety.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The hexagonal connector on the left side of the bearing pipe has an internal thread, which makes it easy to tighten with tools, ensuring a stable connection with the external high-pressure water source, reducing leakage and ensuring stable water pressure; the two symmetrical figure-eight bearing handles above it are ergonomic, which can disperse the reaction force of the high-pressure water flow, improve grip stability, reduce hand fatigue, and ensure that the flushing head is accurately aimed at the wax scale area. 2. The bearing pipe, connecting pipe, and tail pipe are connected by the same threaded interface to achieve modular combination. The number of connecting pipes can be flexibly increased or decreased according to the pipe length to adapt to the wax removal needs of pipes of different lengths and enhance the applicability of the equipment. The threaded connection also facilitates the disassembly and maintenance of each component. When a single component is damaged, it can be replaced individually, reducing maintenance costs and time costs. 3. The flushing head connected to the right side of the tailpipe has a three-lobed spiral structure on the outside that can mechanically scrape away hard wax scale when it rotates. The three first water outlets on the side, which are triangularly distributed and facing backward, form a uniform high-pressure water jet in the circumference. The reaction force of the water flow can drive the flushing head to rotate autonomously, expanding the wax removal range. The second water outlet in the center works with the first water outlet to form a three-dimensional flush, with no dead corners in wax removal. The built-in guide tube stably guides the water flow, reduces pressure loss, ensures uniform jet pressure in each water outlet, and improves the consistency of wax removal effect. 4. The bearing pipe and the protective plate are configured opposite each other. The protective plate can be rotated and adjusted to fit the outer wall of the pipe, effectively blocking high-pressure water jets and wax splashes, protecting the safety of operators. Two sets of symmetrical first and second grippers, together with relevant connecting rods and bearing handles, can compress the spring and open the grippers when the second handle is squeezed. After releasing, the spring returns to its original position and drives the grippers to automatically clamp the pipe. The equipment can be fixed without additional tools, avoiding displacement due to reaction force during flushing, and improving operational stability and safety. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 - Figure 4 The present invention provides a high-pressure water jet dewaxing device for oil pipelines, comprising a bearing pipe 1, a connecting pipe 2, a tail pipe 3, a flushing head 4, a first water outlet 5, a bearing handle 6, a connecting port 7, a protective plate 8, a first handle 9, a first gripper 10, a second gripper 11, a first connecting rod 12, a second handle 13, a second connecting rod 14, a spring 15, a guide pipe 16, and a second water outlet 17. The hexagonal connector 7 on the left side of the carrier pipe 1 is easy to fasten with tools. With the internal thread structure, it can firmly connect to the external high-pressure water source, reduce leakage, and ensure stable water pressure during wax removal. The two symmetrical figure-eight carrier handles 6 above it are ergonomic and can disperse the reaction force of the high-pressure water flow, making it more stable for the operator to hold, reducing hand fatigue, and ensuring that the rinsing head 4 is accurately aimed at the wax scale area. The carrier pipe 1, connecting pipe 2, and tail pipe 3 are connected by the same threaded interface to achieve modular combination. The number of connecting pipes 2 can be flexibly increased or decreased according to the actual length of the oil pipeline to adapt to the dewaxing needs of pipelines of different lengths and expand the application range of the equipment. The threaded connection also facilitates the disassembly and maintenance of each component. When a single component is damaged, it can be replaced individually without the need for the whole system to be scrapped, thus reducing maintenance costs and time costs. The flushing head 4, which is rotatably connected to the right side of the tailpipe 3, has a three-lobed spiral structure on its outer side that can mechanically scrape off hard wax scale on the inner wall of the pipe when it rotates. The three first water outlets 5, which are triangularly distributed on the side and face backward, can form a uniform high-pressure water jet in the circumference. The reaction force of the water flow can also drive the flushing head 4 to rotate autonomously, expanding the wax removal range. The second water outlet 17 in the center cooperates with the first water outlet 5 to form a three-dimensional flushing in the axial and circumferential directions, with no dead corners in wax removal. The built-in guide tube 16 can stably guide the high-pressure water flow, reduce pressure loss, ensure uniform jet pressure in each water outlet, and improve the consistency of the wax removal effect. The carrier pipe 1 and the protective plate 8 are arranged opposite each other. The protective plate 8 can be rotated and adjusted to fit the outer wall of the pipe, effectively blocking high-pressure water jets and wax splashes, and protecting the safety of operators. Two sets of symmetrical first grippers 10 and second grippers 11, together with the first connecting rod 12, the second connecting rod 14 and the second handle 13, form a linkage structure. Squeezing the second handle 13 can compress the spring 15 to open the grippers. After releasing, the spring 15 resets and drives the grippers to automatically clamp the pipe. The equipment can be fixed without additional tools, avoiding displacement due to reaction force during flushing, and improving the stability and safety of operation.

[0014] Working principle: When using a high-pressure water jet dewaxing device for oil pipelines, the device is first connected to an external high-pressure water source through the connection port 7 on the left side of the bearing pipe 1. The hexagonal structure and internal thread of the connection port 7 ensure a stable and sealed connection, guaranteeing a stable input of high-pressure water. The operator holds the two symmetrical figure-eight shaped bearing handles 6 above the bearing pipe 1, using their ergonomic design to disperse the reaction force generated by the high-pressure water flow and maintain stable operation. Subsequently, according to the length of the oil pipeline to be cleaned, the carrier pipe 1, the appropriate connecting pipe 2 and the tail pipe 3 are connected in sequence through the threaded interface to form the main body of the equipment of the appropriate length. The flushing head 4 connected to the right side of the tail pipe 3 enters the pipeline. The three-lobed spiral structure on its outer side begins to rotate under the action of high pressure water flow, mechanically scraping off the hard wax scale on the inner wall of the pipeline. Simultaneously, high-pressure water flows through the bearing pipe 1, connecting pipe 2, and tail pipe 3 into the guide pipe 16 inside the flushing head 4. The guide pipe 16 stably guides the water flow and reduces pressure loss. The water flow is then sprayed out from the three first water outlets 5, which are triangularly distributed on the side of the flushing head 4 and facing backward, and the second water outlet 17, which is located in the center of the right side. The circumferential high-pressure water jet sprayed from the first water outlet 5 further drives the flushing head 4 to rotate autonomously under the reaction force, expanding the wax removal coverage area. It works in conjunction with the axial water flow sprayed from the second water outlet 17 to form a three-dimensional flush, thoroughly removing wax scale from the inner wall of the pipe without any dead corners in the wax removal process. During the wax removal process, the flow-blocking mechanism on the right side of the carrier pipe 1 plays a role. The operator controls the first gripper 10 and the second gripper 11 through the first gripper 9 and the second gripper 13. Squeezing the second gripper 13 compresses the spring 15, and the gripper opens to fit against the outer wall of the pipe. After releasing, the spring 15 resets and drives the gripper to clamp the pipe, thus fixing the equipment and preventing displacement due to reaction force. The protective plate 8 effectively blocks the high-pressure water jet and wax debris splashing, protecting the operator's safety.

[0015] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
