Description

Technical Field

[0001] The utility model relates to the technical field of underground pipeline cleaning, in particular to an underground pipeline outer wall oxide scale cleaning device. Background Art

[0002] Downhole pipeline refers to a pipeline system buried underground for transporting liquids, gases or other substances. These pipelines are usually buried underground to transport various substances without interfering with ground traffic and buildings. In the field of oil and gas extraction, downhole pipelines are used to transport crude oil, natural gas and other related chemical products from the production site to the processing plant or transfer station. The pipelines used in urban water supply systems and sewage treatment systems are mostly buried underground to transport clean tap water and treated sewage. Many chemical plants and industrial facilities use downhole pipelines to transport various chemicals and industrial raw materials, as well as to transport finished products to warehouses or distribution centers. In addition to transporting substances, downhole pipelines are also often used to bury infrastructure such as communication cables and power lines. After the underground pipeline has been used for a long time, the oxide scale cleaning equipment on the outer wall of the underground pipeline is one of the indispensable equipment.

[0003] The equipment for cleaning the outer wall of underground pipelines is used to remove oxide scale and dirt on the surface of underground pipelines. After the pipeline is used for a long time, oxide scale and corrosion products may be generated on its surface. These substances may affect the performance and service life of the pipeline, so regular cleaning is required. The equipment for cleaning the outer wall of underground pipelines usually includes a high-pressure water pump, a nozzle, a compressor, a cleaning agent and other auxiliary equipment. When the equipment enters the underground pipeline, the high-pressure water pump will pressurize and spray the cleaning agent into the inside of the pipeline. The cleaning agent will dissolve or peel off the oxide scale and dirt on the surface of the pipeline, and then the cleaning agent and the peeled oxide scale and dirt will be sucked away by auxiliary equipment such as a dust suction device to achieve the effect of cleaning the surface of the underground pipeline. The use of the equipment for cleaning the outer wall of underground pipelines can effectively remove the oxide scale and dirt on the surface of the pipeline, keep the pipeline in good condition, and extend its service life. In the prior art, the cleaning of underground pipelines usually involves disassembling the pipeline and then using the cleaning equipment to clean the pipeline, which is time-consuming and labor-intensive and cannot meet the needs of use.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: an oxide scale cleaning device for the outer wall of a downhole pipeline, comprising a bottom plate 1, an arc column 7 is fixedly connected to the top rear side of the bottom plate 1, a driving motor 8 is fixedly connected to the top of the arc column 7, a worm 9 is fixedly connected to the output end of the driving motor 8, a worm gear 11 is meshedly connected to the bottom of the worm gear 9, a fixing ring 12 is fixedly connected to the inner side of the worm gear 11, a plurality of convex plates 16 are fixedly connected to the inner wall of the fixing ring 12 at equal intervals, an arc rod 14 is fixedly connected to the front and rear sides of the top of the bottom plate 1, a ball 13 is fixedly connected to the end of the arc rod 14, an annular groove 10 is provided on the front and rear sides of the outer wall of the worm gear 11, a cleaning mechanism 2 is installed on the front side of the top wall of the bottom plate 1; a U-shaped frame 4 is fixedly connected to the right side of the top of the bottom plate 1; a handle 5 is fixedly connected to the right side of the U-shaped frame 4; self-locking wheels 6 are installed at the four corners of the bottom of the bottom plate 1;

[0028] Specifically, the driving motor 8 plays a vital role; after it is started, it can drive the worm 9 to rotate; this rotational motion is further transmitted to the worm wheel 11 through the meshing transmission of the worm 9 and the worm wheel 11; in this process, the rotation of the worm wheel 11 drives the rotation of the fixing ring 12 and the convex plate 16; it is worth mentioning that the sliding of the ball 13 in the ring groove 10 plays a limiting role, ensuring the safety of the rotation of the worm wheel 11; this design makes the equipment more stable and reliable during operation, greatly reducing the risk of failure; in addition, the operation of the equipment is also very convenient; only one end of the pipe needs to be inserted into the fixing ring 12, and two staff members can stand behind the two handles 5; they can push the bottom plate 1 to move, and the self-locking wheel 6 rotates at the same time; in this way, the outer wall of the pipe can be effectively scraped and cleaned; it is worth mentioning that the design of this equipment avoids the cumbersome process of disassembling and installing the pipe; in traditional cleaning equipment, the pipe needs to be frequently disassembled and installed, which is not only time-consuming but also easy to damage the pipe; and the design of this equipment truly achieves the working goal of cleaning without disassembling the pipe, greatly improving work efficiency and reducing maintenance costs.

[0029] Reference Figure 1 and Figure 3 The cleaning mechanism 2 includes a water pump 202, the bottom of which is installed on the front side of the top of the bottom plate 1, the input end of the water pump 202 is connected to the water inlet pipe 201, the front end of the water inlet pipe 201 is connected to the storage bucket 205, the output end of the water pump 202 is connected to the drain pipe 203, and the end of the drain pipe 203 is connected to the atomizing nozzle 204; a storage box 3 is installed on the left side of the top wall of the bottom plate 1;

[0030] Specifically, first, the water pump 202 plays a driving role, and the water source is pumped out from the storage barrel 205 through the water inlet pipe 201; this step ensures the continuous supply of water source and provides a stable foundation for subsequent cleaning work; at the same time, other protective agents can be added to the storage barrel 205 to enhance the cleaning effect; next, the water source is sprayed onto the pipeline through the drain pipe 203 and the atomizing nozzle 204; this spraying method can evenly disperse the water source on the surface of the pipeline, thereby achieving comprehensive cleaning; in addition, this spraying method can also avoid unnecessary pollution to the surrounding environment during the cleaning process; while the cleaning work is in progress, the water source in the storage barrel 205 can also clean the surface of the pipeline; this step can effectively remove dirt on the surface of the pipeline and restore the original appearance of the pipeline. When the water source drips, it can be collected by the storage box 3; this design can not only prevent the ground from being polluted during the dripping process of the water source, but also speed up the work efficiency; in this way, the entire cleaning process is both clean and efficient, fully meeting the needs of modern work.

[0031] Reference Figure 1 The top of the storage bucket 205 is threadedly connected with a bucket cover 15; the outer wall of the handle 5 is frosted;

[0032] Specifically, the water source can be added by rotating the barrel cover 15, and the handle 5 with a frosted design can prevent the handle 5 from slipping out of the hand.

[0033] Working principle: Turn on the driving motor 8 to drive the worm 9 to rotate, and the rotation of the worm 9 is meshed with the worm wheel 11 to drive the worm wheel 11 to rotate at the same time. The rotation of the worm wheel 11 also causes the fixing ring 12 and the convex plate 16 to rotate. When the worm wheel 11 rotates, the ball 13 slides in the ring groove 10 to limit the rotation of the worm wheel 11. Insert one end of the pipe into the fixing ring 12. Two staff members stand at the rear of the two handles 5 to push the bottom plate 1 to move and the self-locking wheel 6 to move. The utility model can rotate to scrape and clean the outer wall of the pipeline, and there is no need to disassemble and install the pipeline, which is time-saving and labor-saving. The water pump 202 is turned on to drive the water inlet pipe 201 to extract water from the storage barrel 205, and the water source is sprayed onto the pipeline through the drain pipe 203 and the atomizing nozzle 204. Other protective agents can also be added to the storage barrel 205. The pipeline surface can be cleaned by the water source. At the same time, the cleaning work can be carried out simultaneously after the cleaning is completed. When the water source drips, it can be collected by the storage box 3, which speeds up the work efficiency.
