Abstract
Description
Technical Field
[0001] This utility model relates to the field of petroleum extraction and storage technology, specifically to an automatic scraping device for an optical oil sensor in an automatic water cutter. Background Technology
[0002] When crude oil and natural gas are pumped to the surface, they contain many impurities (such as water and sand). During actual operation, these impurities are separated, and the water remaining after this separation is called produced water. Produced water contains many hydrocarbons (i.e., oil), which cannot be directly discharged or used. It is necessary to further separate the hydrocarbons from the produced water to meet increasingly stringent environmental protection requirements. To meet these stringent environmental requirements and improve the management of produced water, its quality needs to be monitored during separation. Currently, the most accurate sensor for measuring oil content in water is the optical oil-in-water sensor. However, the hydrocarbon composition in produced water is complex and easily adheres to the window of the optical oil-in-water sensor, rendering the sensor ineffective. Therefore, most optical oil-in-water sensors can only accurately measure the oil content in produced water in a laboratory setting. Utility Model Content
[0003] The purpose of this utility model is to solve at least one of the above-mentioned technical problems and provide an automatic scraping device for an optical water oil sensor in an automatic water cutter, including a pipe, a first window and a second window that are disposed through the wall of the pipe. The first window and the second window are both solid structures in the shape of a stepped shaft. The end faces of the first window and the second window are arranged at intervals and are both disposed inside the pipe. A power motor is installed on the side wall of the pipe. The output end of the power motor is sequentially connected to a scraper seat and a cleaning component disposed on the scraper seat for scraping the end faces of the first window and / or the second window. The cleaning component is located between the first window and the second window.
[0004] In the above technical solution, the cleaning component includes a scraper and a fastening block. The scraper is installed between the fastening block and the scraper seat. The side of the scraper is provided with a scraper lip for scraping off oil stains on the end face of the first window and / or the end face of the second window.
[0005] In the above technical solution, the cross-section of the scraper is V-shaped.
[0006] In the above technical solution, the power unit is a cylinder, and the scraper and the scraper lip are an integral structure and are both made of rubber and plastic materials.
[0007] In the above technical solution, a flange coaxial with the pipe is connected to the inlet and / or outlet of the pipe. The first window and the second window are coaxially arranged, and the center line of the first window and the center line of the second window are both perpendicular to the side wall of the pipe.
[0008] In the above technical solution, a limiting plate is provided inside the pipe to limit the movement of the scraper seat.
[0009] This utility model provides an automatic scraping device for an optical oil sensor in an automatic water cutter, including components such as pipes, a first window, a second window, a power unit, and a cleaning component. Since the cleaning component is located between the first and second windows, after the power unit receives a cleaning command, the power unit can drive the cleaning component through the scraper seat to scrape the end face of the first window and / or the end face of the second window, thereby cleaning the first and second windows to remove oil (impurities) from the end face of the first window and / or the end face of the second window in the water cutting process, thus making the water quality detection results of the drawn water more accurate.

[0015] 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 a part of the embodiments of the present utility model, and not all of them. 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. At the same time, it should be understood that the specific embodiments described herein are merely used to explain the present utility model and are not intended to limit the present utility model.
[0016] like Figure 1 As shown, this utility model provides an automatic scraping device for an optical water-oil sensor in an automatic water cutter. It includes a pipe 11 for the passage of the sampled water, a first window 12 located on one side of the pipe 11, and a second window 13 located on the other side of the pipe 11. A flange coaxial with the pipe 11 is connected to the inlet and / or outlet of the pipe 11 to facilitate connection of components such as the water cutter, thus allowing this invention to be more conveniently applied in water cutting operations.
[0017] Both the first and second windows are solid, stepped, axial structures arranged at intervals. One end of each window (12) is located outside the sidewall of the pipe 11, while the other end penetrates the pipe 11 and lies inside it. The end faces of the first window (12) and the second window (13) are spaced apart and both are located inside the pipe 11. The first window (12) and the second window (13) are coaxially aligned, with their centerlines perpendicular to the sidewall of the pipe 11. This coaxial arrangement of the first window (12) and the second window (13) allows for more accurate detection of the oil content in the extracted water.
[0018] Both the first window 12 and the second window 13 are integrally stepped, cylindrical, transparent, solid structures. When there are impurities (such as oil stains) on the end face of the first window 12 and / or the end face of the second window 13, the power unit 2 drives the cleaning component 5 to scrape the end face of the first window 12 and / or the end face of the second window 13 to remove the impurities (oil stains) so as to accurately detect the oil content in the extracted water.
[0019] A power unit 2 is installed on the side wall of the pipe 11. The power unit 2 is a cylinder. The output end of the power unit 2 passes through the pipe 11 and is connected in sequence to a scraper seat 3 and a cleaning component 5 for scraping the end face of the first window 12 and / or the end face of the second window 13. The scraper seat 3 and the cleaning component 5 are both located inside the pipe 11. Specifically, the scraper seat 3 and the cleaning component 5 are located between the end face of the first window 12 and the end face of the second window 13.
[0020] The cleaning component 5 includes a scraper 51 and a fastening block 52. The scraper 51 is installed between the fastening block 52 and the scraper seat 3. The side of the scraper 51 is provided with a scraping lip 53 for scraping off oil stains from the end face of the first window 12 and / or the end face of the second window 13. The cross-section of the scraper 51 is V-shaped, which is beneficial for scraping. The scraper 51 and the scraping lip 53 are an integral structure and are both made of rubber and plastic materials. Under the action of the scraping lip 53 and the scraper 51, the cleaning component 5 will not damage the end face of the first window 12 and / or the end face of the second window 13 when removing impurities, thereby obtaining a relatively long service life.
[0021] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
