Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to an electronic detection device for the water content of kerosene in an explosion-proof aircraft refueling truck. Background Technology

[0002] In aircraft refueling operations, the water content of kerosene directly affects aviation safety. The water content of aviation kerosene must be strictly controlled below 30 ppm; otherwise, it can easily lead to serious malfunctions such as icing of the engine fuel system and corrosion of components. Existing technologies rely on syringe sampling and water bean colorimetric methods, which consume a lot of consumables, have low detection efficiency, and are prone to errors due to manual operation. These methods can no longer meet the needs of large-scale, automated refueling support. In addition, the operating environment of aircraft refueling trucks is characterized by vibration, large temperature differences, and variable flow rates. The data obtained using existing detection methods have large deviations, affecting the final detection results. Utility Model Content

[0003] The purpose of this utility model is to provide an explosion-proof electronic detection device for the water content of kerosene in aircraft refueling trucks, which can solve the above-mentioned technical problems.

[0004] This utility model provides an electronic detection device for the water content of kerosene in an explosion-proof aircraft refueling truck, comprising:

[0005] A detection device for detecting the water content of fuel is connected to a fuel supply pipeline. The detection device includes: a detection seat, which is installed on the fuel supply pipeline; an adjusting rod, which passes through the detection seat; a detection shell connected to one end of the adjusting rod, and having several through holes; and several detection bodies, which are installed inside the detection shell.

[0006] The display and control device is connected to the detection device.

[0007] As a further technical solution, the detection seat includes:

[0008] Connector body, for connection to the oil supply pipeline;

[0009] A limiting groove is provided at one end of the connecting body, and one end of the detection shell is placed in the limiting groove.

[0010] As a further technical solution, the testing station also includes:

[0011] A support groove is provided at the other end of the connector, and a support block is provided inside the support groove. One end of the adjusting rod passes through the support block and the connector in sequence and is then connected to the detection shell.

[0012] As a further technical solution, a first bearing groove is provided in the limiting groove, and a first sealed bearing is provided in the first bearing groove.

[0013] As a further technical solution, a second bearing groove is provided in the support block, and a second sealed bearing is provided in the second bearing groove.

[0014] As a further technical solution, a flange plate is provided on the outer surface of the connector.

[0015] As a further technical solution, the support block is provided with several positioning holes, and several positioning components are provided in the positioning holes.

[0016] As a further technical solution, a sealing cover is provided at one end of the detection shell, and a mounting bracket is provided on the sealing cover, with several detection bodies mounted on the mounting bracket.

[0017] As a further technical solution, several detection bodies include:

[0018] The micro water sensor, temperature sensor, and pressure sensor are respectively mounted on the mounting bracket and connected to the display and control device via wires.

[0019] As a further technical solution, it also includes: a pipe seat, which is connected to the oil supply pipeline, and the detection device is installed on the pipe seat.

[0020] The technical solution of this utility model, through the cooperative structure of the detection seat and the adjusting rod, allows for flexible adjustment of the angle of the detection shell within the fuel supply pipeline. This ensures that after the detection seat is aligned with the fuel supply pipeline, the several through holes on the detection shell can be precisely aligned with the mainstream direction of the fluid, ensuring that the oil in the fuel supply pipeline can enter the detection shell for detection by several detection elements. Furthermore, the through hole design on the detection shell guides the fuel to flow smoothly through the detection elements, reducing fluid impact interference caused by varying flow rates. Simultaneously, the coordinated detection by several detection elements effectively offsets the impact of operating environments such as vibration and large temperature differences on the data, significantly reducing detection errors and improving the reliability of the results.

[0021] In addition, the technical solution of this utility model can detect online in real time without the need for manual sampling and comparison with color cards, which greatly shortens the detection time and meets the needs of large-scale and automated refueling. At the same time, it avoids the continuous consumption of consumables such as syringes and water testing beads, significantly reducing long-term use costs and reducing the workload of operators.

[0034] like Figure 1-6 As shown, the present invention proposes an electronic detection device for the water content of kerosene in an explosion-proof aircraft refueling truck, comprising:

[0035] A detection device 100 is connected to a fuel supply pipeline. When fuel flows through the pipeline, the detection device 100 detects the water content of the fuel. The detection device 100 includes: a detection seat 101 mounted on the fuel supply pipeline; an adjusting rod 102 passing through the detection seat 101; a detection housing 103 connected to one end of the adjusting rod 102, and having several through holes 104; and several detection elements disposed within the detection housing 103. In use, the detection seat 101 is installed into the mounting holes on the fuel supply pipeline. After installation, the detection housing 103 is placed inside the oil supply pipeline, and the several detectors inside the housing are communicatively connected to the display and control device 200. When oil flows through the oil supply pipeline, the oil will enter the detection housing 103 through several through holes 104 and come into contact with the detectors, and the water content of the oil will be detected by the detectors. The detection results will be sent to the display and control device 200, which will display the detection data. The detection housing 103 is made of 316L stainless steel explosion-proof alloy material, and the housing wall thickness is not less than 5mm.

[0036] In this utility model, the display and control device 200 includes a housing, and a PLC control board is installed inside the housing and connected to the display screen on the housing. After the detection data of several detectors is transmitted, it is placed on the control board, and the acquired data is transmitted to the display screen through the control board, and the corresponding detection results are displayed on the display screen. At the same time, the detection housing 103 and several detectors are located in the oil supply pipeline, so the oil in the oil supply pipeline can be detected in real time, thereby better obtaining the water content of the oil during the transmission process. The housing of the display and control device 200 is made of cast aluminum explosion-proof shell, and the internal PLC control board is intrinsically safe (Ex ia IIB T4 Ga level intrinsically safe modification).

[0037] It should be noted that the display and control device 200 is connected to several detection objects through wires passing through the adjustment rod 102 and the detection housing 103, and transmits the detection data of several detection objects through the wires.

[0038] The technical solution of this utility model, through the cooperative structure of the detection seat 101 and the adjustment rod 102, can flexibly adjust the angle of the detection shell 103 in the fuel supply pipeline. This ensures that after the detection seat 101 is aligned with the fuel supply pipeline, the several through holes 104 on the detection shell 103 can be accurately aligned with the mainstream direction of the fluid, ensuring that the oil in the fuel supply pipeline can enter the detection shell 103 for detection by several detection elements. The design of the through holes 104 on the detection shell 103 can guide the fuel to flow smoothly through the detection element, reducing fluid impact interference caused by changes in flow rate. At the same time, the coordinated detection of several detection elements effectively offsets the influence of operating environment such as vibration and large temperature difference on the data, significantly reducing detection errors and improving the reliability of the results.

[0039] In addition, the technical solution of this utility model can detect online in real time without the need for manual sampling and comparison with color cards, which greatly shortens the detection time and meets the needs of large-scale and automated refueling. At the same time, it avoids the continuous consumption of consumables such as syringes and water testing beads, significantly reducing long-term use costs and reducing the workload of operators.

[0040] like Figure 2 As shown, the detection seat 101 includes a connector 111 connected to the oil supply pipeline; a limiting groove 112 is formed at one end of the connector 111, and one end of the detection shell 103 is placed in the limiting groove 112; the connector 111 is connected to the mounting hole on the oil supply pipeline, so that the detection shell 103 is placed in the oil supply pipeline; when oil flows through the oil supply pipeline, the oil will impact the detection shell 103. Since one end of the detection shell 103 is set in the limiting groove 112, the detection shell 103 can remain stable under the impact of the oil under the support of the limiting groove 112.

[0041] In addition, the detection seat 101 also includes a support groove 113 opened at the other end of the connecting body 111, and a support block 106 is provided in the support groove 113. One end of the adjusting rod 102 passes through the support block 106 and the connecting body 111 in sequence and is connected to the detection shell 103. After the connecting body 111 is connected to the mounting hole, the adjusting rod 102 needs to be rotated, and the adjusting rod 102 drives the detection shell 103 to rotate at the same time. This ensures that the several through holes 104 on the detection shell 103 are aligned with the direction of oil flow, so that the oil can enter the detection shell 103 better. When the adjusting rod 102 is adjusted, the supporting block 106 limits the adjusting rod 102 to prevent the adjusting rod 102 from moving left or right, thus ensuring the stability of the adjusting rod 102. The diameter of the through hole is 0.05-0.1 mm, preferably 0.08 mm.

[0042] like Figure 4 As shown, a first bearing groove 114 is provided in the limiting groove 112, and a first sealed bearing 115 is provided in the first bearing groove 114; a second bearing groove 161 is provided in the support block 106, and a second sealed bearing 162 is provided in the second bearing groove 161; by setting the first sealed bearing 115 and the second sealed bearing 162, it is possible to ensure that the detection housing 103 can rotate when the adjusting rod 102 rotates; at the same time, it is possible to prevent oil from overflowing through the limiting groove 112 and the support groove 113, thus ensuring the overall sealing performance;

[0043] Furthermore, the mounting hole structure varies for different oil supply pipelines. Therefore, in this invention, a flange plate 107 is provided on the outer surface of the connector 111. This allows the connector 111 to be connected to the mounting hole, or the flange plate 107 to be rotated and connected to the mounting hole, depending on the structure of the oil supply pipeline. Additionally, a sealing ring (fluororubber sealing ring) is fitted on the surface of the connector 111. When connected to the mounting hole, the sealing ring increases the sealing between the connector 111 and the mounting hole, preventing oil leakage. In this invention, the outer surface of the connector 111 is threaded, and it is threaded to the mounting hole of the oil supply pipeline through the external thread.

[0044] like Figure 2 or Figure 3As shown, the support block 106 has several positioning holes, and several positioning elements 108 are provided in the several positioning holes. After the connecting body 111 is connected to the mounting hole, the angle of the detection shell 103 is adjusted by the adjusting rod 102. After the adjustment is completed, the several positioning elements 108 are adjusted to the positions of the several positioning holes and then contact the adjusting rod 102. The several positioning elements 108 cooperate to limit the adjustment rod 102, so as to prevent the adjustment rod 102 from rotating during use, changing the angle of the detection shell 103 and affecting the detection results. In this utility model, it is preferred to provide 3 positioning holes, and 3 positioning elements 108 are provided in conjunction with the 3 positioning holes. The positioning elements 108 are bolts.

[0045] like Figure 6 As shown, this utility model also includes a pipe seat 300, which is connected to the oil supply pipeline. The connector 111 or flange plate 107 on the detection device 100 is connected to the pipe seat 300. When the detection device 100 is connected to the pipe seat 300, the oil supply pipeline is connected to both ends of the pipe seat 300. During oil transportation, the oil flows through the pipe seat 300 and is detected by the detection device 100. Preferably, the pipe seat 300 has flange plates 107 at both ends, which are connected to the flanges of the oil supply pipeline on both sides. The pipe seat 300 is made of carbon steel Q235B with anti-corrosion treatment on the inner wall. The connection between the pipe seat 300 and the detection device 100 is equipped with an explosion-proof sealing ring (made of fluororubber). The compression of the sealing ring is controlled at 20%-30% to ensure sealing and explosion prevention.

[0046] like Figure 4 and Figure 5 As shown, a sealing cover 131 is provided at one end of the detection housing 103, and a mounting bracket 132 is provided on the sealing cover 131, with several detection bodies mounted on the mounting bracket 132; wherein, the sealing cover 131 is threadedly connected to the inner wall of the detection housing 103; this allows for the assembly and disassembly of the mounting bracket 132 and the several detection bodies. If a component is damaged during subsequent use, the sealing cover 131 can be separated from the detection housing 103, and the detection bodies can be disassembled and replaced.

[0047] In this invention, several detection elements, including a micro-water sensor 151, a temperature sensor 152, and a pressure sensor 153, are respectively mounted on a mounting bracket 132 and connected to a display and control device 200 via wires. Specifically, the mounting bracket 132 is provided with a mounting ring, and the micro-water sensor 151, temperature sensor 152, and pressure sensor 153 are respectively press-fitted to the mounting ring to ensure the stability of the micro-water sensor 151, temperature sensor 152, and pressure sensor 153 after installation. The micro-water sensor 151, temperature sensor 152, and pressure sensor 153 all adopt an intrinsically safe explosion-proof design (Exia IIB T4). (Ga-grade intrinsically safe sensor); In addition, a first wire hole is provided in the adjusting rod 102, and the first wire hole is connected to a second wire hole inside the mounting bracket. The wire passes through the first wire hole and the second wire hole in sequence and connects with the micro-water sensor 151, temperature sensor 152 and pressure sensor 153. At the same time, the connection position can be sealed with oil-resistant and explosion-proof sealant; At the same time, oil-resistant and explosion-proof sealant is filled into the first wire hole and cured to form a rigid sealing layer to ensure that oil will not enter the first wire hole from the second wire hole; The wire is an intrinsically safe shielded wire (Exia IIB T4 Ga grade).

[0048] During testing, when the oil enters the detection housing 103, it simultaneously comes into contact with the micro-moisture sensor 151, temperature sensor 152, and pressure sensor 153. The three sensors detect the water content, temperature, and pressure of the oil. The detection results are then transmitted to the display and control device 200. After acquiring the data, the display and control device 200 uses a PLC control board to comprehensively analyze the data collected by the micro-moisture sensor 151, temperature sensor 152, and pressure sensor 153, corrects errors caused by environmental interference, and obtains the final water content result, which is then displayed on the screen.

[0049] In addition, the display and control device 200 is connected to the valve on the fuel supply pipeline via a wire. When the detection result shows that the water content of the fuel does not meet the usage requirements, it will send a signal to the valve to close the valve and stop the fuel injection into the aircraft.
