Description

Technical Field

[0001] This utility model relates to a leak prevention monitoring and alarm device for oil and gas storage tanks, belonging to the field of oil and gas storage tank level monitoring technology. Background Technology

[0002] Oil and gas storage tanks are critical equipment used in the petroleum, chemical, and other industries to store crude oil, refined oil products, and other liquid chemicals. Real-time and accurate monitoring of their internal liquid levels is essential for inventory management, safe production, and environmental protection. Abnormal liquid levels, especially abnormal drops, are often a direct indication of tank leaks. Failure to detect and address these leaks promptly can lead to significant economic losses, environmental pollution, and even safety accidents.

[0003] Currently, liquid level monitoring of oil and gas storage tanks generally relies on on-site observation. This involves installing a glass or transparent plastic liquid level tube connected to the inside of the tank on its side, with a scale fixed next to it. Workers need to periodically visit the tank location and visually read the scale value corresponding to the liquid level in the tube to obtain the current liquid level data. This on-site observation method has several drawbacks. First, it is highly dependent on manual labor, requiring workers to frequently travel between tanks to record data. When there are many tanks or they are geographically dispersed and remote, this consumes a significant amount of manpower and time, resulting in low monitoring efficiency. Second, manual observation cannot achieve continuous monitoring; leaks occurring between observations cannot be detected immediately, creating blind spots and delayed response. Furthermore, manual readings are prone to errors due to factors such as viewing angle and lighting, and in adverse weather conditions, worker observation operations face difficulties and safety risks. Therefore, researching a new type of leak prevention monitoring and alarm device for oil and gas storage tanks is of great practical significance. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a leak prevention monitoring and alarm device for oil and gas storage tanks.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an oil and gas storage tank leakage prevention monitoring and alarm device, comprising: an oil and gas storage tank;

[0006] A liquid level indicating component includes a mounting bracket disposed on one side of the oil and gas storage tank, a liquid level tube communicating with the oil and gas storage tank disposed on the mounting bracket, and a scale for indicating the liquid level height in the liquid level tube.

[0007] A sliding assembly includes a guide portion, the guide portion including a slide rail and a slider that slides with the slide rail. The slide rail is mounted on the fixed frame and located on one side of the liquid level tube. The cross-sectional shape of the slide rail is a C-shaped structure with one side open, and the length of the slide rail is not less than the length of the liquid level tube. The slider is at least partially located within the opening area of ​​the slide rail. The slider is connected to a power unit, and the power unit is used to drive the slider to reciprocate along the length extension direction of the slide rail.

[0008] A monitoring component, connected to the slider, is used for remote monitoring of liquid level changes;

[0009] Warning component, which is used to issue a warning signal when the liquid level is abnormal.

[0010] Furthermore, the power unit includes mounting plates disposed at the upper and lower ends of the slide rail, a lead screw is rotatably disposed between the two mounting plates, the lower end of the lead screw passes through the mounting plate located at the lower end of the slide rail and is connected to the drive motor, and the slider is sleeved on the lead screw and engaged with the lead screw.

[0011] Furthermore, the portion of the slider located within the opening area of ​​the slide rail is provided with a spring piece. The spring piece is located on both sides of the slider, with one end connected to the slider and the other end extending obliquely towards the inner wall of the slide rail and abutting against the inner wall of the slide rail.

[0012] Furthermore, the monitoring component includes a connecting plate connected to the slider, and a miniature camera with image recognition function is provided on the connecting plate, with its lens facing the liquid level tube and the scale.

[0013] Furthermore, the monitoring component also includes a vibration damping part, which includes three screws disposed on the contact surface between the slider and the connecting plate. The three screws are arranged in a triangular pattern. The connecting plate is sleeved on the screws and has through holes corresponding to the positions of the screws.

[0014] The vibration damping part also includes a compression spring and a pressure plate sleeved on the screw. One end of the compression spring abuts against the connecting plate, and the other end abuts against the pressure plate. The bolt passes through the pressure plate and is fixed by a fastening bolt.

[0015] Furthermore, the miniature camera is encapsulated within the explosion-proof housing, and the bottom of the explosion-proof housing is secured by bolts that penetrate the connecting plate.

[0016] Furthermore, the connecting plate has a strip-shaped hole at the position where the explosion-proof shell is fixed, and the length extension direction of the strip-shaped hole is perpendicular to the length extension direction of the liquid level tube.

[0017] Furthermore, the scale markings on the ruler are reflective.

[0018] Furthermore, the fixing frame, the slide rail, the slider, the mounting plate, the lead screw, the connecting plate, and the vibration damping part are all made of stainless steel.

[0019] Furthermore, the warning component includes a warning light and a buzzer.

[0020] The beneficial effects of this utility model are as follows: First, while ensuring the traditional on-site observation function, the above settings realize the remote monitoring function, which can continuously monitor the liquid level gauge remotely. This solves the problem that the traditional monitoring method requires staff to frequently observe the liquid level on-site, which consumes a lot of time and manpower and is inconvenient for observing scattered and remote storage tanks. Second, when the monitoring component determines that the liquid level is abnormally higher or lower than the preset normal liquid level range, it will immediately send a signal to the warning component. After receiving the signal, the warning component can quickly issue an audible and visual alarm to remind staff to take timely measures to deal with abnormal situations such as leakage. This avoids safety hazards caused by untimely or misjudgment of manual observation, and can quickly respond to abnormal liquid levels to ensure the safe operation of oil and gas storage tanks.

[0030] Example:

[0031] like Figure 1-4 As shown, this utility model provides a leak prevention monitoring and alarm device for an oil and gas storage tank 1, comprising: an oil and gas storage tank 1; a liquid level indicating component, which includes a fixed frame disposed on one side of the oil and gas storage tank 1, the fixed frame being welded to one side of the oil and gas storage tank 1, a liquid level pipe 2 communicating with the oil and gas storage tank 1 disposed on the fixed frame, and a scale 3 for indicating the liquid level height in the liquid level pipe 2; a sliding component, which includes a guide portion, the guide portion including a slide rail 4 and a slider 5 slidably engaged with the slide rail 4, the slide rail 4 being mounted on the fixed frame and located on one side of the liquid level pipe 2, and the cross-section of the slide rail 4 being... The slide rail 4 has a C-shaped structure with an opening on one side, and its length is not less than that of the liquid level tube 2. The slider 5 is at least partially located within the opening area of ​​the slide rail 4. The slider 5 is connected to a power unit, which drives the slider 5 to reciprocate along the length extension direction of the slide rail 4. A monitoring component is connected to the slider 5 and is used to remotely monitor changes in liquid level. An alarm component is used to issue an alarm signal when the liquid level is abnormal. It should be noted that the alarm component and the monitoring component are connected wirelessly. When the monitoring component detects an abnormal liquid level, it will send a signal to the alarm component.

[0032] First, while ensuring the traditional on-site observation function, the above settings enable remote monitoring, allowing for continuous remote monitoring of the liquid level gauge. This solves the problem of traditional monitoring methods requiring frequent on-site observation of the liquid level, which is time-consuming and labor-intensive, and inconvenient for observing dispersed and remote storage tanks. Second, when the monitoring component detects that the liquid level is abnormally high or low, exceeding or falling below the preset normal liquid level range, it immediately sends a signal to the warning component. Upon receiving the signal, the warning component quickly issues an audible and visual alarm, reminding staff to take timely measures to deal with abnormal situations such as leaks. This avoids safety hazards caused by untimely or misjudgment of manual observation, and enables rapid response to abnormal liquid levels, ensuring the safe operation of oil and gas storage tank 1.

[0033] Specifically, such as Figure 2-4 As shown, the power unit includes mounting plates 6 disposed at the upper and lower ends of the slide rail 4. A lead screw 7 is rotatably disposed between the two mounting plates 6. The lower end of the lead screw 7 passes through the mounting plate 6 located at the lower end of the slide rail 4 and is connected to the drive motor 8. The slider 5 is sleeved on the lead screw 7 and is engaged with the lead screw 7. It should be noted that the mounting plates 6 are welded to the upper and lower ends of the slide rail 4. A rolling bearing is disposed at the position where the lower end of the lead screw 7 passes through the mounting plate 6. The drive motor 8 is mounted and fixed on the lower surface of the mounting plate 6 through a motor frame. Through this arrangement, the slider 5 can move up and down reciprocally, thereby enabling the slider 5 to drive the monitoring component to move up and down. Furthermore, by setting the slider 5 to be at least partially located within the opening area of ​​the slide rail 4, the stability of the slider 5 during movement can be improved, thereby ensuring the monitoring accuracy of the monitoring component.

[0034] Specifically, such as Figure 4 As shown, the portion of the slider 5 located within the opening area of ​​the slide rail 4 is equipped with a spring piece 9. The spring piece 9 is located on both sides of the slider 5, with one end connected to the slider 5 and the other end extending obliquely towards the inner wall of the slide rail 4 and abutting against the inner wall. It should be noted that the spring piece 9 and the slider 5 are integrally formed during machining. This design ensures that the spring piece 9 continuously abuts against the inner wall of the slide rail 4 during the movement of the slider 5, effectively restraining the slider 5 and preventing it from shifting or wobbling during movement. This further ensures the stability of the slider 5 during movement, guaranteeing smooth movement of the monitoring component and avoiding inaccurate image acquisition due to movement deviation, which would affect the identification and monitoring results of the liquid level scale, thus improving the reliability of the entire monitoring process. Secondly, it allows for the simultaneous cleaning of dirt, dust, and other impurities from the inner side of the slide rail 4 during the sliding of the slider 5, preventing movement jamming and effectively extending the maintenance cycle.

[0035] Specifically, such as Figure 2As shown, the monitoring component includes a connecting plate 10 connected to the slider 5. A miniature camera with image recognition function is provided on the connecting plate 10, and its lens is facing the liquid level tube 2 and the scale 3.

[0036] Specifically, such as Figure 2 As shown, the monitoring component also includes a vibration damping section, which includes three screws 11 disposed on the contact surface between the slider 5 and the connecting plate 10. The three screws 11 are arranged in a triangular pattern. The connecting plate 10 is sleeved on the screws 11, and has through holes corresponding to the positions of the screws 11. The vibration damping section also includes a compression spring 12 and a pressure plate 13 sleeved on the screws 11. One end of the compression spring 12 abuts against the connecting plate 10, and the other end abuts against the pressure plate 13. The bolt passes through the pressure plate 13 and is fixed by a fastening bolt 14. It should be noted that The screw 11 is fixed to the slider 5 by welding. Tightening the fastening bolt 14 can increase the preload on the connecting plate 10. This setting can firstly reduce the vibration of the monitoring components during operation, avoid the influence of operating vibration or the surrounding environment on the miniature camera, greatly reduce the error of the monitoring group, and further ensure the accuracy of monitoring. Secondly, when the connecting plate 10 or the miniature camera is damaged, the connecting plate 10 can be removed by unscrewing the fastening bolt 14 and then removing the pressure plate 13 and the compression spring 12, which saves time and effort and greatly improves maintenance efficiency.

[0037] Specifically, such as Figure 2 As shown, the miniature camera is encapsulated within the explosion-proof housing 15, and the bottom of the explosion-proof housing 15 is fixed by bolts passing through the connecting plate 10. This design fully considers the special environment of the oil and gas storage tank 1 area. Since flammable and explosive gases may exist around the oil and gas storage tank 1, the operation of the internal circuit components of the miniature camera during operation may generate potential hazards such as electrical sparks. The explosion-proof housing 15 has excellent sealing and explosion-proof performance, effectively preventing internal electrical sparks from contacting external flammable and explosive gases, thus preventing explosions. This structure ensures the safe use of the miniature camera in hazardous environments, enabling the entire oil and gas storage tank 1 leak prevention monitoring and alarm device to operate normally under safe and reliable conditions, protecting the safety of the oil and gas storage tank 1 and its surrounding environment.

[0038] Specifically, such as Figure 2 As shown, the connecting plate 10 has a strip-shaped hole 16 at the position where the explosion-proof housing 15 is fixed. The length extension direction of the strip-shaped hole 16 is perpendicular to the length extension direction of the liquid level tube 2. This setting allows for fine adjustment of the position of the miniature camera to ensure that it is in the optimal working angle.

[0039] Specifically, the scale mark on the scale 3 is a reflective scale mark. When the monitoring component is monitoring, the reflective scale mark can enhance the light reflection at the liquid level scale. Even in poor lighting or interference environments, the miniature camera can more clearly and accurately identify the liquid level scale, thereby improving the reliability of monitoring.

[0040] Specifically, the fixing frame, the slide rail 4, the slider 5, the mounting plate 6, the lead screw 7, the connecting plate 10, and the vibration damping part are all made of stainless steel. Given that corrosive gases or liquids may exist around the oil and gas storage tank 1, stainless steel has excellent corrosion resistance, effectively resisting the erosion of the structure by harsh environments, extending the overall service life of the device, ensuring the long-term stable operation of the leak prevention monitoring and alarm device described in this application, and providing a guarantee for continuous and accurate monitoring.

[0041] Specifically, the warning components include a warning light and a buzzer. The warning light and buzzer can be placed in a position that is easy for staff to see, depending on the actual environment, and therefore are not shown in the accompanying drawings.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are exhaustively listed. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these modifications and improvements are all within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims.
