Description

Technical Field

[0001] This utility model relates to crude oil transportation and water content measurement, and in particular to the housing structure of a rapid oil-water tester. Background Technology

[0002] Crude oil metering is a crucial step in oilfield production, and measuring the water content in crude oil is a vital technical indicator for this process. Existing methods for measuring crude oil water content generally include capacitance, radio frequency, conductivity, and microwave methods. Water content analyzers typically come in two structural types: in-line and insertion type. After reviewing relevant materials and products, it was found that most existing water content analyzer probes are mounted on the side of the pipe or inserted into the pipe, with very few having the probe positioned at the bottom. This means that when the flow rate in the pipe is low and the liquid cannot fully immerse the probe, the water content of the crude oil cannot be measured.

[0003] A search revealed Chinese patent document CN202420701234.8, which discloses a pipe-section online crude oil water content analyzer. This analyzer places two electrode plates at the bottom of the pipe and uses the capacitance principle to analyze the water content of crude oil. It can accurately detect water content even under low liquid volume conditions, exhibiting good adaptability to such conditions. It can promptly and effectively reflect changes in water content, can be directly connected to a straight section of pipeline, and is suitable for online monitoring of light oil wells, heavy oil wells, high liquid volume wells, and low liquid volume wells.

[0004] Regardless of the principle used, the sensor probe of a water content analyzer must be completely immersed in the measured medium. The above solution cannot automatically store the oil when the oil volume is small, making it inconvenient to immerse the probe and affecting the detection of crude oil water content. In addition, the overall circuit is external, which may cause damage to the instrument during transportation, handling and installation. Furthermore, the meter head cannot be quickly disassembled and assembled, making it inconvenient for on-site installation and use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a housing structure for an oil-water rapid tester, which solves the problems that when the oil volume is small, it cannot automatically store the oil, making it inconvenient to immerse the probe, thus affecting the detection of water content in crude oil. At the same time, the overall circuit is external, which may cause damage to the instrument during transportation, handling and installation, and the meter head cannot be quickly disassembled and assembled, making it inconvenient for on-site installation and use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a housing structure for a rapid oil-water tester, including a device outer shell, a protective shell outside the device outer shell, an electrode mounting base inside the bottom of the device outer shell, an electrode plate inside the electrode mounting base, fixed baffles inside the device outer shell on both sides of the electrode plate, a meter mounting rod on the protective shell, the meter mounting rod having a hollow structure and communicating with the protective shell, a measuring meter at the end of the meter mounting rod, and the measuring meter being assembled and connected to the meter mounting rod via a clamp assembly.

[0007] As one embodiment of this application, the fixed baffle has a semi-circular structure, and the arrangement height of the fixed baffle is higher than the arrangement height of the electrode plate, which enables the storage of crude oil liquid.

[0008] As one embodiment of this application, the electrode mounting base is connected to the device housing via a mounting base fixing plate.

[0009] As one embodiment of this application, a mounting sleeve is provided on the measuring head, and the mounting sleeve is connected to the measuring head mounting rod, which enables the measuring head to be assembled with the measuring head mounting rod.

[0010] As one embodiment of this application, an annular mounting cavity is provided at the connection between the mounting sleeve and the meter mounting rod, and an O-ring is provided in the annular mounting cavity to ensure the airtightness of the meter head and the meter mounting rod.

[0011] As one embodiment of this application, the clamp assembly includes a front clamp and a rear clamp, which are respectively positioned at the connection between the mounting sleeve and the meter mounting rod, and can lock and fix the mounting sleeve and the meter mounting rod.

[0012] As one embodiment of this application, an upper positioning pin is provided on one side of both the front clamp and the rear clamp. The upper positioning pin is engaged in the upper positioning groove, which is provided on both sides of the outer surface of the mounting sleeve, so as to position the front clamp and the rear clamp on both sides of the mounting sleeve.

[0013] As one embodiment of this application, a lower positioning pin is provided on the other side of both the front clamp and the rear clamp. The lower positioning pin is engaged in the lower positioning groove, which is respectively provided on both sides of the meter mounting rod, so that the front clamp and the rear clamp can be positioned on both sides of the meter mounting rod.

[0014] The beneficial effects of this utility model are: 1. By setting fixed baffles, when the medium flow rate is too small, a storage space is formed between the two sets of fixed baffles to store the crude oil liquid, so that the electrode plate is completely immersed, thus ensuring the accuracy of the detection of the moisture content in the crude oil liquid.

[0015] 2. This application integrates all electrical connections into the protective housing and meter connecting rod, which not only improves the appearance but also effectively prevents impacts and avoids damage to the instrument during transportation, handling, and installation. It also saves installation space and makes on-site installation and use more convenient.

[0016] 3. This application enables the rapid assembly of the measuring head and the measuring head mounting rod, while also providing good overall installation stability and convenient assembly operation. Attached Figure Description

The electrode plate 11 is disposed inside the electrode mounting base 9. A meter mounting rod 2 is disposed on the protective shell 4. The meter mounting rod 2 is a hollow structure, with one end welded to the protective shell and communicating with the protective shell 4. A measuring meter 7 is disposed at the end of the meter mounting rod 2. In this application, the electrical connection wire is... Electrical connections are made within the protective housing 4 mounted on the surface of the device housing 5. Simultaneously, the connecting wires of the electrode plates 11 pass through the meter head connecting rod and connect to the various modules within the measuring meter head 7. The bottom electrode plates 11 and the top measuring meter head 7 are connected via electrical wires, thereby enabling the transmission and acquisition of electrode detection signals. This design integrates all electrical connections within the housing, resulting in an aesthetically pleasing appearance, effective protection against impacts, and prevention of instrument damage during transportation, handling, and installation.
