A leak-proof oil level sensor for large tanks

Abstract

This utility model provides a leak-proof oil gauging sensor for large tanks, relating to the field of sensor technology. It addresses the problem that existing oil gauging sensors are typically fixed in a designated position inside large tanks, making flexible monitoring based on oil volume inconvenient. The sensor includes: a mating screw and a connecting block; a displacement block slidably connected to the mating screw; a fixing plate fixed to the connecting block; a monitoring component fixed to the center of the fixing plate; an oil seepage groove at the bottom of the monitoring component; and an oil gauging contact inside the oil seepage groove. The mating screw is rotatably connected to the shaft hole of an external adjustment slot via an end torsion block. The operator only needs to insert a tool into the external adjustment slot and rotate the mating screw to move the displacement block up and down along the sliding groove of the inner sleeve, thereby adjusting the position of the monitoring component and the oil gauging contact. This adjustment method does not require opening the oil tank and allows for precise control of the contact height between the oil gauging contact and the oil from outside the tank.

Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, and more specifically, it relates to a large tank oil volume sensor that prevents oil leakage. Background Technology

[0002] In the petroleum, chemical, and energy sectors, large oil storage tanks serve as core storage equipment for crude oil, refined oil, and various chemical oils. The accurate measurement of parameters such as liquid level, temperature, and density within these tanks directly impacts key aspects like production scheduling, inventory management, safety control, and cost accounting. With the continuous expansion of industrial production, the volume of large oil storage tanks is constantly increasing, significantly raising the requirements for accuracy, real-time performance, and safety in oil measurement. Traditionally, oil measurement in large storage tanks relies primarily on manual and mechanical methods. Manual measurement often uses simple tools such as dipsticks and sampling bottles, requiring operators to climb to the top of the tank for manual measurement. Mechanical measurement typically employs float-type or steel belt-type mechanical sensors, converting liquid level changes into mechanical or electrical signals through mechanical transmission. However, early leaks are difficult to detect promptly, and large-scale leaks can cause severe environmental pollution and economic losses. Therefore, to prevent large tank leaks, an oil measurement sensor is needed.

[0003] Based on existing technology, it has been found that existing oil level sensors are usually fixed in a designated position inside a large tank and cannot be flexibly adjusted. As a result, when monitoring the oil level, the oil level inside needs to reach a certain level, making it inconvenient to flexibly monitor the oil volume. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a leak-proof oil level sensor for large tanks. This addresses the issue that existing oil level sensors are typically fixed at a specific location inside the large tank, requiring the oil level to reach a certain point before monitoring, thus hindering flexible monitoring and processing based on oil storage levels.

[0005] This utility model provides a leak-proof oil level sensor for large tanks, achieved through the following specific technical means:

[0006] An oil leakage-proof large tank gauging sensor includes: an oil storage tank; a sealing port at the top of the oil storage tank; a torsion sealing block internally threaded into the sealing port; an external adjustment groove at the top of the torsion sealing block; a sealing collar fitted at the bottom of the torsion sealing block; an inner extension sleeve fixedly connected to the bottom of the torsion sealing block; a mating screw rotatably connected inside the inner extension sleeve; a displacement block slidably connected to the mating screw; a mating slot on a fan-shaped protrusion of the displacement block; a mating side block fixedly connected to the outside of the fan-shaped protrusion of the displacement block; a fixing plate fixedly connected to the mating side block; a monitoring component fixedly connected to the center of the fixing plate; an oil seepage groove at the bottom of the monitoring component; an oil gauging contact inside the oil seepage groove; and a locking sleeve externally threaded into the monitoring component.

[0007] Preferably, the inner wall of the sealing port is connected with threads; the outer wall of the torsion sealing block is provided with threads for cooperating with the sealing port.

[0008] Preferably, the bottom of the external adjustment slot is connected to a shaft hole; the sealing ring is inserted into the sealing port, and the torsion sealing block is sealed to the oil storage tank through the sealing ring.

[0009] Preferably, the inner sleeve has a hollow cavity structure, a sliding groove is provided on the outer wall of the inner sleeve, and a shaft hole is provided at the end of the inner sleeve; a torsion block is fixedly connected to the end of the mating screw, and the torsion block of the mating screw is rotatably connected in the shaft hole of the outer adjusting groove.

[0010] Preferably, the displacement block has a threaded through hole at its center, and the outer wall of the displacement block has a fan-shaped protrusion for sliding connection with the inner sleeve sliding groove; the mating side block has a protrusion for insertion into the mating slot; and the mating side block has a circular mounting hole.

[0011] Preferably, the monitoring component is inserted into the mounting hole of the docking side block; the outer wall of the monitoring component is provided with threads; and the top of the monitoring component is provided with external wiring.

[0012] Preferably, the oil measuring contact is electrically connected to the monitoring component; the outer wall of the locking sleeve is provided with a hexagonal prism-shaped protrusion for cooperating with external tools.

[0013] The oil level sensor for large tanks that prevents oil leakage proposed in this utility model has the following beneficial effects:

[0014] 1. The monitoring component works in conjunction with the gauging contact to not only monitor changes in oil volume at normal levels, but also to provide real-time early warnings for abnormal oil leaks. When an oil leak occurs at the bottom of the storage tank or at the pipe interface, the oil will escape from the gauging contact through the seepage groove. The monitoring component triggers an early warning through the abnormal change signal in oil volume and transmits it to the external control system through the top external wiring.

[0015] 2. The sliding groove of the inner sleeve constrains the fan-shaped protrusion of the displacement block, preventing the displacement block from rotating and shifting during lifting and lowering. The screw is connected to the shaft hole of the outer adjustment slot through the end torsion block. The operator only needs to insert the tool into the outer adjustment slot and rotate the screw to drive the displacement block to rise and fall along the sliding groove of the inner sleeve, thereby adjusting the position of the monitoring component and the measuring oil contact. This adjustment method does not require opening the oil tank and can accurately control the contact height between the measuring oil contact and the oil outside the tank, adapting to oil storage scenarios with different liquid levels.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, the protrusion on the mating side block 10 is aligned with the mating slot 9 of the fan-shaped protrusion on the displacement block 8, and slowly inserted until the protrusion is fully embedded in the mating slot 9. At this point, the mating side block 10 and the displacement block 8 are initially positioned. The circular mounting hole on the mating side block 10 is checked to ensure it is horizontally aligned, ensuring that the monitoring component 12 can be installed vertically. The monitoring component 12 is then pushed upwards from the bottom of the circular mounting hole on the mating side block 10, exposing the oil seepage groove 13 at the bottom of the monitoring component 12. The locking sleeve 15 is then taken, and its inner thread is aligned with the outer thread of the monitoring component 12. A wrench is used to engage the hexagonal prism-shaped protrusion on the outer wall of the locking sleeve 15. The locking sleeve 15 is rotated clockwise until it is tightly fitted to the bottom of the mating side block 10, and simultaneously, the top of the monitoring component 12 is in close contact with the fixing plate 11. To achieve clamping and locking of the monitoring component 12, ensuring no loosening or shaking, the tool is inserted into the external adjustment slot 4 to rotate the cooperating screw 7. When rotated clockwise, the cooperating screw 7 drives the displacement block 8 to move downward along the sliding groove of the inner extension sleeve 6; when rotated counterclockwise, the displacement block 8 moves upward. According to the estimated oil level in the oil storage tank 1, the displacement block 8 is adjusted to a suitable height so that the oil measuring contact 14 at the bottom of the monitoring component 12 is close to the oil surface, ensuring that the oil measuring contact 14 can accurately contact the oil. An appropriate amount of oil is injected into the oil storage tank 1, keeping the oil level within the seepage groove 13, ensuring that the oil and the oil measuring contact 14 remain in contact. When oil leakage occurs, the oil separates from the oil measuring contact 14, making the oil measuring contact 14 unable to detect the presence of oil. Then, the monitoring component 12 sends a trigger signal to the external control center, thereby issuing an alarm.
