Abstract
Description
Technical Field
[0001] This utility model relates to the field of petroleum transportation technology, specifically a pipeline corrosion protection device for petroleum storage and transportation. Background Technology
[0002] Oil transportation refers to the process of transporting oil from production sites or processing plants to consumption sites or end-use sites. Pipeline transportation is the main mode of transporting fluids on land and near the coast. Long-distance pipelines include crude oil pipelines and refined oil pipelines. These pipelines are usually used for long-distance, large-volume oil transportation. Pipeline transportation has low cost, requires little land, has low investment, and is quick to construct. It is easy to operate, has a large oil transport capacity, and is easy to automate.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: When oil needs to be stored and transported, pipelines are frequently used. In order to ensure the quality of the pipelines, it is necessary to spray anti-corrosion materials on the inner wall of the pipeline. Since most sandblasting guns lack cleaning mechanisms, in actual use, impurities remaining in the pipeline and anti-corrosion materials are easily mixed, affecting the anti-corrosion effect. Therefore, in order to address the above problems, a pipeline anti-corrosion device for oil storage and transportation is proposed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A pipeline corrosion protection device for oil storage and transportation, comprising a sprayer and a cleaning device, wherein multiple moving parts are fixedly connected to the surface of the sprayer, and a nozzle is fixedly connected to the side wall of the sprayer; the cleaning device is disposed on the surface of the sprayer, and includes two fixing rings, which are sleeved on the surface of the sprayer. Two sleeves are fixedly connected to the surface of the fixing rings, and threaded rods are threadedly connected to the inner walls of the two sleeves. A cleaning brush is fixedly connected to the inner surface of the threaded rod, and the cleaning brush is fixed to the surface of the threaded rod. When the sprayer moves, it drives the cleaning brush to move, and the cleaning brush moves inside the pipeline. By setting the cleaning brush, the pipeline can be cleaned, reducing the mixing of impurities with the corrosion protection material.
[0006] Preferably, limiting rings are fixedly connected to both sides of the sprayer surface near the fixed ring. When the fixed ring moves, the fixed ring will fit against the limiting rings, and the limiting rings can restrict the position of the fixed ring on the sprayer surface.
[0007] Preferably, a scale is fixedly connected to the surface of the threaded rod. The scale is located on one side of the sleeve. The surface of the scale has multiple scale grooves. When the threaded rod moves, the threaded rod will drive the scale to move. The position of the threaded rod is determined by reading the scale grooves.
[0008] Preferably, the sleeve has a threaded hole on its surface, and the surface of the threaded rod is threadedly connected to the inner wall of the threaded hole of the sleeve. When the threaded rod rotates, it rotates within the threaded hole of the sleeve. The threaded hole facilitates the rotation of the threaded rod within the sleeve.
[0009] Preferably, a knob is fixedly connected to the surface of the threaded rod. When using the threaded rod, pushing the knob causes the threaded rod to rotate, and the knob facilitates the operation of the threaded rod.
[0010] Preferably, the surface of the nozzle is provided with a protective device, which includes a support column. The side wall of the support column is fixedly connected to the side wall of the nozzle. A protective block is rotatably connected to the surface of the support column. The protective block is located on the surface of the nozzle. Magnetic blocks are fixedly connected to both sides of the nozzle surface near the protective block. The side wall of the magnetic block and the side wall of the protective block are magnetically attracted. When the protective block rotates to the surface of the nozzle and the magnetic block, the magnetic block attracts the protective block. By setting the protective block, the nozzle can be protected.
[0011] Preferably, limit blocks are fixedly connected to both sides of the nozzle, and limit pins are threadedly connected to the inner walls of the limit blocks and the guard block. By rotating the limit pins to the inner walls of the limit blocks and the guard block, the position of the guard block can be restricted.
[0012] The advantages of this utility model are:
[0013] 1. When the sprayer needs to be used, two fixing rings are fixed to the surface of the sprayer. When the fixing rings move, they will fit against the limiting ring. Then, push the knob to make the knob drive the threaded rod to rotate. The threaded rod rotates in the inner wall of the threaded hole of the sleeve. The threaded rod will move its position. When the threaded rod moves, it will drive the scale to move. When the scale moves, the data of the scale groove is read. After the threaded rod extends to the appropriate position, stop turning the knob. Then fix the cleaning brush on the threaded rod. When the sprayer moves, the sprayer will drive the cleaning brush to slide. The cleaning brush moves in the pipe. During the use of the sprayer, the nozzle will spray anti-corrosion material, which will stick to the inner surface of the pipe. By setting up the whole device, the inner wall of the pipe can be cleaned, reducing the situation where the anti-corrosion material mixes with impurities, thus affecting the anti-corrosion effect.
[0014] 2. When using the sprayer, the protective block is pushed to rotate on the surface of the support column. After the protective block is in contact with the limiting block, the limiting pin is rotated to the inner wall of the limiting block and the protective block. When the sprayer is not in use, the protective block is pushed to rotate to the surface of the magnetic block and the nozzle. The magnetic block holds the protective block. By setting the entire device, the occurrence of dust or small stones entering the nozzle can be reduced. Attached Figure Description

When the sprayer 1 moves, it drives the cleaning brush 44 to move, allowing the cleaning brush 44 to move within the pipeline. By using the cleaning brush 44, the pipeline can be cleaned, reducing the mixing of impurities with the corrosion protection material.
[0024] Limiting rings 45 are fixedly connected to both sides of the surface of the sprayer 1 near the fixing ring 41; during operation, the fixing ring 41 will fit against the limiting ring 45, and the limiting ring 45 can restrict the position of the fixing ring 41 on the surface of the sprayer 1.
[0025] A scale 46 is fixedly connected to the surface of the threaded rod 43. The scale 46 is located on one side of the sleeve 42. The surface of the scale 46 has multiple scale grooves 47.
