[0002] The capacitance method is a crude oil water content detection method based on the difference in dielectric constants between crude oil and water. It estimates the water content by measuring the capacitance value of the crude oil sample between electrodes. Because the dielectric constant of water is much higher than that of crude oil, changes in water content will cause a significant change in the capacitance value. The capacitance method is fast, easy to operate, and low in cost, making it suitable for rapid on-site detection and continuous online monitoring, providing efficient technical support for production process control and quality assurance in the petroleum industry.

[0003] In the field of crude oil water content detection, the capacitance method is widely used due to its high efficiency and convenience. However, in existing technologies using the capacitance method, the detection probe needs to be inserted into the crude oil for measurement, and a large amount of crude oil often remains on the probe surface after the measurement. This residual crude oil not only contaminates the detection equipment but may also introduce errors in subsequent measurements, affecting detection accuracy and repeatability. In addition, cleaning the residual crude oil from the probe is time-consuming and increases operational complexity, reducing detection efficiency.

[0004] Therefore, the present invention provides a modular and quick-installation crude oil water content detection probe to solve the above problems. Utility Model Content

[0024] This disclosure aims to address the problem in existing capacitive testing methods where the probe needs to be inserted into the crude oil for measurement, often leaving a large amount of crude oil residue on the probe surface after measurement. This residual crude oil not only contaminates the testing equipment but may also introduce errors in subsequent measurements, affecting detection accuracy and repeatability. Furthermore, cleaning the residual crude oil from the probe is time-consuming, increases operational complexity, and reduces detection efficiency. Therefore, this disclosure proposes a modular, quick-installation crude oil moisture content detection probe. Through modular design, the probe can be quickly installed and disassembled. The fixing device utilizes a fixing groove, mounting groove, locking groove, and sliding block in conjunction with the elasticity of a strong spring, allowing the probe to be quickly and securely fixed to the detection cable. Simultaneously, the conductive plate in the fixing groove cooperates with the conductive plate on the top of the mounting block, ensuring stable electrical signal transmission and improving detection efficiency and accuracy. In the cleaning device, the cleaning ring slides for cleaning via a limiting rod, and a fixing magnet holds the cleaning ring in place when not in use, keeping the equipment clean. The placement groove on the cleaning ring contains an oil-absorbing sponge that can absorb residual oil and prevent contamination. The scraper at the contact point effectively removes crude oil residue from the probe surface, further improving the cleaning effect, reducing manual maintenance costs, extending the service life of the equipment, and significantly improving the overall performance and practicality of the detection system.

[0025] like Figures 1 to 4As shown, a modular, quick-installation crude oil water content detection probe includes a detection device 1, a detection cable 2, a detection probe 3, a fixing device 4, and a cleaning device 5. The detection device 1 is fixed to the ground, and the detection cable 2 is installed on the detection device 1. The detection probe 3 is installed at one end of the detection cable 2. The fixing device 4 is installed between the detection probe 3 and the detection cable 2. The fixing device 4 is used to enable quick installation and disassembly of different specifications. The cleaning device 5 is installed on the fixing device 4. The cleaning device 5 is used to clean the detection probe 3 after detection, thereby avoiding residual oil.

[0026] The modular design enables rapid installation and disassembly of the crude oil water content detection probe 3. The fixing device 4, utilizing the cooperation of the fixing groove 42, mounting groove 46, locking groove 43, and sliding block 48, combined with the elasticity of the strong spring 47, allows the detection probe 3 to be quickly and securely fixed to the detection cable 2. Simultaneously, the conductive sheet 421 within the fixing groove 42 cooperates with the conductive sheet 421 on the top of the mounting block 45, ensuring stable transmission of electrical signals and improving detection efficiency and accuracy. In the cleaning device 5, the cleaning ring 52 achieves sliding cleaning via the limiting rod 51. The fixing magnet 53 attracts the cleaning ring 52 when not in use, keeping the equipment clean. The placement groove 54 on the cleaning ring 52 contains an oil-absorbing sponge 55 to absorb residual oil and prevent contamination. The scraper 56 at the contact point effectively scrapes away crude oil residue from the probe surface, further improving the cleaning effect, reducing manual maintenance costs, extending equipment lifespan, and significantly improving the overall performance and practicality of the detection system.

[0027] like Figures 1 to 4 As shown, the fixing device 4 includes a fixing block 41, a fixing groove 42, a locking groove 43, an unlocking block 44, a mounting block 45, a mounting groove 46, a strong spring 47, and a sliding block 48. The fixing block 41 is mounted on the detection cable 2 and is used to fix the mounting block 45 in conjunction with the fixing groove 42. The fixing block 41 has a fixing groove 42 for fixing the mounting block 45. The fixing block 41 has locking grooves 43 on both sides and the locking grooves 43 are connected to the fixing grooves 42. The locking grooves 43 are used to lock the sliding block 48. The unlocking block is slidably disposed in the locking groove 43. 44; Unlocking block 44 is used to press and unlock the locking groove 43 from locking the sliding block 48; The mounting block 45 is installed above the detection probe 3, and the mounting block 45 is used to cooperate with the fixing groove 42 to fix the detection probe 3; The mounting block 45 is symmetrically provided with mounting grooves 46, and the mounting grooves 46 are used to install the strong spring 47; The strong spring 47 is installed in the mounting groove 46, and the strong spring 47 is used to make the sliding block 48 snap into the locking groove 43; The sliding block 48 is installed on the strong spring 47, and the end of the sliding block 48 is arc-shaped and the diameter of the sliding block 48 is smaller than the inner diameter of the mounting groove 46;

[0028] During operation, the operator inserts the detection probe 3 with mounting block 45 into the fixing groove 42. At this time, the sliding block 48 inside the mounting block 45 is squeezed by the fixing groove 42. Under the pressure of the fixing groove 42, the sliding block 48 squeezes the strong spring 47 and moves into the mounting groove 46. At this time, the operator can push the mounting block 45 to move within the fixing groove 42. After the mounting block 45 has moved within the fixing groove 42, the mounting groove 46 is aligned with the locking groove 43. The sliding block 48 is squeezed by the fixing groove 42 and extends into the locking groove 43 to complete the fixation. At this time, the detection probe 3 is connected to the cable. When unlocking is required, simply press the unlocking block 44 to squeeze the sliding block 48 and retract the sliding block 48 into the mounting groove 46. At this time, the mounting block 45 can be pulled out from the fixing groove 42.

[0029] The cleverly designed fixing device 4 enables rapid installation and removal of the detection probe 3. Utilizing the cooperation of the fixing slot 42, mounting slot 46, locking slot 43, sliding block 48, and strong spring 47, the detection probe 3 is automatically secured upon insertion, and can be easily unlocked and removed by pressing the unlocking block 44. This design significantly improves the efficiency of probe 3 replacement, reduces operation steps and time, and avoids the risk of equipment damage due to frequent disassembly and assembly, thus enhancing the reliability and practicality of the detection system.

[0030] like Figure 4 As shown, a conductive sheet 421 is provided in the fixing groove 42, and a matching conductive sheet 421 is provided on the top of the mounting block 45. By providing matching conductive sheets 421 in the fixing groove 42 and on the top of the mounting block 45, a quick electrical connection between the detection probe 3 and the detection cable 2 is achieved. When the detection probe 3 is inserted into the fixing groove 42 and mechanically fixed, the contact of the conductive sheet 421 ensures stable transmission of electrical signals, eliminating the need for additional electrical connection operations and further improving the installation efficiency and convenience of the detection probe 3. At the same time, this design also ensures the reliability and stability of signal transmission, avoids detection errors caused by poor contact, and improves the performance and accuracy of the entire detection system.

[0031] like Figures 1 to 4 As shown, the cleaning device 5 includes a limiting rod 51, a cleaning ring 52, and a fixing magnet 53. The limiting rod 51 is symmetrically mounted on the fixing block 41 and is used to limit the cleaning ring 52. The cleaning ring 52 is mounted on the limiting rod 51 and is used to clean residual crude oil on the detection probe 3. The inner diameter of the cleaning ring 52 is larger than the diameter of the detection probe 3. The fixing magnet 53 is provided above the cleaning ring 52 and below the fixing block 41 and is used to attract the cleaning ring 52 when not in use.

[0032] During operation, after the detection probe 3 completes the detection, the staff pushes the cleaning ring 52 to disengage it from the fixed magnet 53 and slide it on the limit rod 51, thereby cleaning the crude oil left on the detection probe 3.

[0033] By incorporating the cleaning device 5, the problem of residual crude oil in the detection probe 3 after use is effectively solved. The cleaning ring 52 can slide on the limiting rod 51, ensuring thorough cleaning of the surface of the detection probe 3 and removing residual crude oil. This avoids interference from residual crude oil in subsequent tests, improving detection accuracy and reliability. Simultaneously, the design of the fixing magnet 53 allows the cleaning ring 52 to be securely attached to a fixed position when not in use, preventing it from moving freely and ensuring the overall stability and cleanliness of the equipment. This design of the cleaning device 5 not only improves the maintenance efficiency of the detection probe 3 but also reduces equipment contamination and measurement errors caused by incomplete cleaning of residual oil, significantly enhancing the practicality and ease of operation of the entire detection system.

[0034] like Figures 1 to 4 As shown, a placement groove 54 is provided above the cleaning ring 52, and an oil-absorbing sponge 55 is placed inside the placement groove 54. The placement groove 54 above the cleaning ring 52 and the oil-absorbing sponge 55 further enhance the functionality of the cleaning device 5. The oil-absorbing sponge 55 can absorb residual crude oil during the cleaning process, preventing the crude oil from dripping again or contaminating the equipment and working environment. This design not only improves cleaning efficiency and ensures a more thorough cleaning of the surface of the detection probe 3, but also reduces safety hazards and environmental pollution caused by residual oil dripping, improves the cleanliness and maintenance convenience of the entire detection system, and reduces the labor intensity and time cost during the cleaning process.

[0035] like Figures 1 to 4 As shown, a scraper 56 is provided at the contact point between the cleaning ring 52 and the detection probe 3. This scraper 56 effectively removes crude oil residue adhering to the surface of the detection probe 3. This design significantly enhances the decontamination capability of the cleaning device 5, ensuring a cleaner surface for the detection probe 3 after cleaning and avoiding detection errors and equipment contamination caused by residual oil. The combination of the scraper 56 and the oil-absorbing sponge 55 achieves a dual cleaning effect of mechanical scraping and physical adsorption, further improving cleaning efficiency and quality.

[0036] The overall working process is as follows: The operator inserts the detection probe 3 with the mounting block 45 into the fixing groove 42. At this time, the sliding block 48 inside the mounting block 45 is squeezed by the fixing groove 42. Under the squeezing of the fixing groove 42, the sliding block 48 squeezes the strong spring 47 and moves into the mounting groove 46. At this time, the operator can push the mounting block 45 to move within the fixing groove 42. After the mounting block 45 has moved within the fixing groove 42, the mounting groove 46 is aligned with the locking groove 43. The sliding block 48 is squeezed by the fixing groove 42 and extends into the locking groove 43 to complete the fixation. At this time, the detection probe 3 is connected to the cable. When unlocking is required, simply press the unlocking block 44 to squeeze the sliding block 48 and retract the sliding block 48 into the mounting groove 46. At this time, the mounting block 45 can be pulled out from the fixing groove 42.

[0037] When it is necessary to clean the detection probe 3, the staff pushes the cleaning ring 52 to disengage it from the fixed magnet 53 and slides it on the limit rod 51, thereby cleaning the crude oil left on the detection probe 3.
