Description

Technical Field

[0001] This invention relates to the field of oil spill testing technology, specifically to a simulation test device for leaks in underground oil storage facilities. Background Technology

[0002] In recent years, with economic development and social progress, the petrochemical industry and transportation industry have developed rapidly, resulting in increasingly serious pollution. During the transportation of industrial organic compounds, leaks are inevitable, and the pollution of soil and groundwater by leaked oil has received increasing attention.

[0003] Current oil spill simulation devices typically only allow for simulation experiments on a single substance (such as clay, silt, or medium sand). If simulations of multiple different substances are required, the device must be removed after each experiment and replaced with a new substance for repeated testing. This process is not only time-consuming and labor-intensive but also severely impacts testing efficiency.

[0004] Therefore, we propose a simulation test device for underground oil storage facility leakage in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A simulation test device for underground oil storage facility leakage includes a housing containing several simulation chambers. A leakage pipe is installed inside the housing, penetrating all the simulation chambers, with both ends extending to the outside of the housing. Several sets of leakage ports are located inside the leakage pipes, used to leak oil into different simulation chambers. An adjusting pipe is rotatably installed inside each leakage pipe, with several sets of first adjusting ports that cooperate with the leakage ports. When the adjusting pipe rotates and adjusts these first adjusting ports, some ports become misaligned with the leakage ports, thus sealing the leakage ports. When the remaining first adjusting ports are aligned with the leakage ports, the oil in the adjusting pipe leaks sequentially through the first adjusting ports and the leakage ports into the corresponding simulation chambers.

[0007] Furthermore: a water pump is installed outside the housing, the pump's pumping end is sealed to a pumping pipe, and one end of the pumping pipe extends into the housing for pumping water from the pumping pipe; the pump's outlet end is sealed to an outlet pipe, and the outlet pipe is equipped with several branch pipes, which are respectively connected to the interior of the simulation housing for supplying water to the interior of the simulation housing.

[0008] Furthermore, each of the branch pipes is equipped with a valve, which is used to open or close the branch pipe; and the valve is located outside the simulation box and inside the box.

[0009] Furthermore, several ground-penetrating radar detection hosts are installed on the outside of the enclosure. The ground-penetrating radar detection hosts are connected to the detection elements via wires. The detection elements are placed inside the simulation enclosure to detect the state of oil leakage within the simulation enclosure.

[0010] Furthermore: when the first adjustment ports of two adjacent groups extend to the axis of the leaking pipe, there is a certain angle between the two first adjustment ports and the extension line of the leaking pipe.

[0011] According to the claim, a simulation test device for leakage of underground oil storage facilities is characterized in that: the regulating pipe is further provided with a number of second regulating ports, the number of second regulating ports being located on the same straight line, and when the number of second regulating ports are aligned with the number of leakage ports at the same time, the oil in the regulating pipe leaks into different simulation boxes at the same time.

[0012] Furthermore, the two ends of the leaking pipe are respectively fixed with limiting protrusions, and the two ends of the regulating pipe are respectively fixed with annular limiting seats, and the limiting protrusions are rotatably installed inside the annular limiting seats to restrict the movement of the regulating pipe along the axial direction of the leaking pipe.

[0013] Furthermore, a sealing sleeve is provided between the two annular limiting seats, and the sealing sleeve has a through hole that matches the first adjustment port and the second adjustment port.

[0014] Furthermore, both ends of the leaking pipe are respectively flanged and connected to conveying pipes, and the ends of the conveying pipes are sealed to the ends of the leaking pipes.

[0015] Furthermore: the end of the conveying pipe is provided with an enlarged hole, and the end of the adjusting pipe is inserted into the enlarged hole; a number of positioning protrusions are fixed at equal intervals along the circumferential direction inside the enlarged hole, and a number of positioning grooves are provided at equal intervals along the circumferential direction at the end of the adjusting pipe, and the number of positioning protrusions and the number of positioning grooves are inserted into each other to restrict the adjustment pipe from rotating in the axial direction.

[0016] The beneficial effects of this invention are: 1. This invention features a plurality of leak ports on a leaking pipeline and a regulating pipe installed inside the leaking pipeline in a rotatable manner. When several sets of second regulating ports on the regulating pipe are simultaneously aligned with the leak ports on the leaking pipeline, the oil in the leaking pipeline can leak into different simulation boxes through the cooperation of the second regulating ports and the leak ports, allowing the oil to spread in different substances. With the cooperation of the ground-penetrating radar detection host and detection elements, multiple detections of various substances can be performed simultaneously, reducing operational procedures and alleviating the workload of workers; in addition, it also improves work efficiency.

[0017] 2. This invention has several sets of first adjustment holes on the regulating pipe. When the regulating pipe drives the several sets of first adjustment holes to rotate, one set of first adjustment holes is set to correspond with the leakage hole to achieve communication; the remaining first adjustment holes are set to be staggered with the leakage holes to achieve sealing. The oil in the regulating pipe enters the corresponding simulation box through the corresponding first adjustment hole and the leakage hole in sequence, thereby enabling the detection of a single substance. This allows for flexible switching according to the user's needs, realizing multiple different simulation test functions and improving the effectiveness of the device. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0021] A simulation test device for underground oil storage facility leakage includes a housing 1, inside which are arranged several simulation boxes 2, which are arranged side by side. The simulation boxes 2 are arranged so that different substances (e.g., clay, silt, or medium sand) can be stored inside each simulation box 2 for multiple leakage detections, thereby enabling multi-functional detection and improving the effectiveness of the device. It should be noted that a water storage area is formed between the outside of the simulation boxes 2 and the inside of the housing 1, which can transport water from the water storage area to different simulation boxes 2, allowing the substances to be detected for leakage under different humidity conditions.

[0022] Inside the housing 1, a leakage pipe 3 is fixed along its length, and both ends of the leakage pipe 3 extend to the outside of the housing 1, enabling the delivery of oil into the interior of the leakage pipe 3; the leakage pipe 3 is provided with several sets of leakage ports 4, which are located inside the simulation housing 2; thus, oil can be leaked into the interior of several simulation housings 2 to achieve the detection function. A water pump 7 is installed on the outside of the tank 1. The pump 7 is sealed to a pump pipe 8, and one end of the pump pipe 8 extends into the tank 1, thereby pumping water from the tank 1. The pump 7 is sealed to an outlet pipe 9, and several branch pipes 10 are installed at equal intervals on the outlet pipe 9. One end of each branch pipe 10 is connected to the inside of the simulation tank 2. Through the cooperation of the pump 7, the outlet pipe 9, and the branch pipes 10, water can be delivered to the inside of several simulation tanks 2. It should be noted that each branch pipe 10 is equipped with a valve (not shown in the figure). The valve can be a solenoid valve or a manual valve. By setting the valve, several branch pipes 10 can be controlled individually, which plays a role in controlling the delivery of water to the inside of the simulation tank 2.

[0023] The exterior of the housing 1 is also equipped with several ground-penetrating radar detection hosts 11. The ground-penetrating radar detection hosts 11 are connected to the detection element 12 via wires. Typically, the detection element 12 is a detection radar. Both the ground-penetrating radar detection hosts 11 and the detection element 12 are known prior art, and will not be described in detail in this application. It is used to detect the extent to which leaked oil spreads to the surrounding area in the material.

[0024] Inside the leakage pipe 3, a regulating pipe 5 is rotatably installed, and several sets of first regulating ports 6 are equidistantly opened on the regulating pipe 5; and several sets of first regulating ports 6 are corresponding to the leakage ports 4. It should be noted that when two adjacent sets of first regulating ports 6 extend to the axis of the leakage pipe 3, there is a certain angle between the two first regulating ports 6 and the extension line of the leakage pipe 3; when the regulating pipe 5 drives several sets of first regulating ports 6 to rotate and adjust, when some of the first regulating ports 6 are misaligned with the leakage ports 4, they are used to block the leakage ports 4; when the remaining first regulating ports 6 are aligned with the leakage ports 4, the oil in the regulating pipe 5 leaks into the corresponding simulation box 2 in sequence through the first regulating ports 6 and the leakage ports 4, thereby realizing the leakage of oil into the interior of a single simulation box 2; used for the detection of a single substance.

[0025] The regulating pipe 5 is also provided with several second regulating ports 13, and these ports 13 are set in correspondence with the leak ports 4. It should be noted that the ports 13 are located on the same straight line. When the regulating channel 5 drives the ports 13 to rotate, the ports 13 can be aligned with the leak ports 4 simultaneously. This allows the oil in the regulating pipe 5 to leak into the simulation boxes 2 simultaneously through the ports 13 and the leak ports 4. This enables the oil to leak into different simulation boxes at the same time, thus allowing for multi-directional leak detection of different substances and improving detection efficiency.

[0026] It should be noted that: the two ends of the leakage pipe 3 are respectively fixed with limiting protrusion rings 14, and the two ends of the regulating pipe 5 are respectively fixed with annular limiting seats 15. The limiting protrusion rings 14 are rotatably installed inside the annular limiting groove 15. Through the cooperation of the limiting protrusion rings 14 and the annular limiting seats 15, the regulating pipe 5 is limited, preventing the regulating pipe 5 from moving along the axis of the leakage pipe 3, and ensuring that the leakage port 4 is always set in correspondence with the first regulating port 6 and the second regulating port 13. A sealing sleeve 16 is provided between the two annular limiting seats 15. Under normal circumstances, the sealing sleeve 16 is fixed on the outer circumferential surface of the regulating pipe 5, and the outer circumferential surface of the sealing sleeve 16 is sealed and fitted with the inner circumferential surface of the leakage pipe 3 to prevent leakage. Several sets of through holes 17 are provided on the sealing sleeve 16, and the several sets of through holes 17 are respectively aligned with the first regulating port 6 and the second regulating port 13. The through holes 17 are provided to ensure that the oil in the regulating pipe 5 can leak normally.

[0027] During use, both ends of the leakage pipe 3 are usually sealed and connected to the delivery pipe 18. It should be noted that: the end of the leakage pipe 3 is fixed with a flange 22, and one end of the delivery pipe 18 is also fixed with a flange 22. One end of the delivery pipe 18 passes through the flange 22, so that one end of the delivery pipe 18 can be inserted into the inside of the leakage pipe 3. When the two flanges 22 are fitted together, they are fixedly connected by bolts. This method is called flange connection, which can seal and fix the leakage pipe 3 and the delivery pipe 18, reducing the possibility of leakage during use.

[0028] The end of the conveying pipe 18 is provided with an enlarged hole 19, and the end of the regulating pipe 5 is inserted into the enlarged hole 19. It should be noted that a sealing ring (not shown in the figure) is fitted on the regulating pipe 5, and the sealing ring is pressed between the conveying pipe 18 and the annular limiting seat 15. The sealing ring plays a sealing role, reducing the possibility of oil leakage from the connection between the regulating pipe 5 and the conveying pipe 18, thus avoiding unnecessary waste.

[0029] The interior of the enlarged hole 19 is fixed with several positioning protrusions 20 at equal intervals along the circumferential direction. The end of the regulating pipe 5 is provided with several positioning grooves 21 at equal intervals along the circumferential direction. When one end of the regulating pipe 5 is inserted into the interior of the enlarged hole 19, the several positioning protrusions 20 and the several positioning grooves 21 are connected to each other, thereby limiting the regulating pipe 5 and preventing the regulating pipe 5 from rotating inside the leaking pipe.

[0030] Working principle: This simulation experimental device has two simulation modes: the first mode can simultaneously leak oil into multiple different substances to measure the extent to which the leaked oil spreads in different substances; the second mode can leak oil into a single substance to measure the extent to which the leaked oil spreads in that single substance. Users can choose flexibly according to their needs, making it highly practical.

[0031] When using the first simulation experiment method; First, the regulating pipe 5 inside the leaking pipe 3 needs to be rotated and adjusted so that the several second regulating ports 13 on the leaking pipe 3 are aligned with the leaking port 4, and then the adjustment work is completed.

[0032] Secondly, one end of the conveying pipe 18 is inserted into the inside of the enlarged hole 19, so that several positioning protrusions 20 and several positioning grooves are inserted and matched. Then, the two flanges 22 that fit together are flanged together. On the one hand, this serves to seal and fix the leaking pipe 3 and the conveying pipe 18, and on the other hand, it serves to limit the position of the regulating pipe 5 to prevent the regulating pipe 5 from rotating during use.

[0033] Then, different materials (e.g., clay, silt, or medium sand) are placed inside several of the simulation boxes 2; then the detection element 12 is placed inside the material, and subsequent detection is performed; Finally, oil is transported into the regulating pipe 5 through the transport pipe 18. The oil in the regulating pipe 5 leaks into the corresponding simulation box 2 through the second regulating port 13 and the leakage port 4 in sequence. The degree of oil spread is detected by the detection element 12. The detection element 12 transmits the detected structure to the ground-penetrating radar detection host 11, and the ground-penetrating radar detection host 11 detects the state of oil spread in different substances.

[0034] When using the second simulation experiment method; First, the regulating pipe 5 inside the leaking pipe 3 is rotated and adjusted so that one set of second regulating ports 13 on the leaking pipe 3 is aligned with the leaking port 4, while the remaining second regulating ports 13 are misaligned with the leaking port 4, thereby achieving the purpose of sealing and completing the adjustment work.

[0035] Secondly, the conveying pipe 18 and the regulating pipe can be fixed in the same way as described above, and will not be described in detail here. Then, the corresponding simulation box 2 is filled with material, and the detection element 12 is placed inside the material for subsequent detection. Finally, oil is transported into the regulating pipe 5 through the conveying pipe 18, and the oil in the regulating pipe 2 is transported through the corresponding... The oil leaks into the interior of the simulation chamber 2 through the regulating port 13 and the leakage port 4. The extent of oil spread is detected by the detection element 12. The detection element 12 transmits the detected structure to the ground-penetrating radar detection host 11, which detects the state of oil spread in different substances.
