Description

Technical Field

[0001] This utility model belongs to the field of gas station technology, and in particular relates to a water level detection device for the oil tank area of ​​a gas station. Background Technology

[0002] As the core hazard source of the refueling station, the oil tank area is responsible for storing a large amount of flammable and explosive oil products such as gasoline and diesel. Its safe operation is of paramount importance to the safety management of the refueling station. During the flood season, especially when encountering extreme weather such as typhoons and short-term heavy rainfall, the oil tank area is located in a low-lying area and is prone to water accumulation. If the water level continues to rise and submerges key parts such as the unloading port and metering port of the oil tank, it may lead to oil leakage. At the same time, water immersion may also cause a series of secondary disasters such as tank floating, pipeline rupture, and electrical equipment short circuits, triggering incalculable environmental disasters and explosion and fire accidents, seriously threatening the lives and property safety of employees in the station, surrounding people, and the ecological environment.

[0003] Currently, most refueling stations still rely on traditional manual inspections to monitor water levels in oil tank areas. Inspection personnel must go to the site in bad weather and judge the water depth by visual observation and experience. This method has significant limitations: First, it has poor real-time performance and cannot respond to rapid rises in water levels within minutes or even seconds, resulting in blind spots in early warning. Second, it has low safety, as heavy rainfall is often accompanied by lightning, and personnel activities in dangerous areas are inherently risky. Third, it lacks reliability, as manual judgment is prone to errors at night or in low visibility conditions, and it cannot generate continuous monitoring data records.

[0004] Therefore, there is an urgent need for a dedicated water level detection device that can adapt to the special environment of oil tank areas, be flexible in installation, reliable in detection, and capable of automatic real-time monitoring. Summary of the Invention

[0005] The purpose of this invention is to provide a water level detection device for oil tank areas in gas stations. Utilizing a non-contact ultrasonic ranging principle, the sensor does not directly contact the accumulated water, fundamentally avoiding contamination, adhesion, and corrosion of the sensor head by oil and impurities. This ensures the long-term stability and reliability of the monitoring data, enabling continuous automatic water level monitoring. Once the water level exceeds a preset threshold, an alarm is immediately issued, providing valuable time for managers to take emergency measures and improving the safety of oil tank areas in gas stations.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a water level detection device for oil tank area of ​​gas station, including a waterproof tank, an ultrasonic sensor and a column installed in oil tank area of ​​gas station; The column has a flange at the bottom and an elbow section at the top. The elbow section and the column form an acute angle and are reinforced with a stiffener. The stiffener has a number of internal mounting ports linearly distributed and parallel to the elbow section. A waterproof interface is provided through the bottom periphery of the column. The waterproof chamber is a cylindrical shell with an open bottom. The top of the waterproof chamber is integrally connected to a cylindrical insertion section through a necked section and a bend section. The insertion section is slidably disposed within the bend section. The waterproof chamber is distributed parallel to the column. The inner side of the turning section is provided with a connecting ear, and two connecting sides are connected by a lower pin on both sides of the connecting ear. The top of the connecting side is provided with two external mounting holes. The distance between the two external mounting holes is the same as the distance between the two adjacent internal mounting holes. The top of the two connecting sides is fixed to the stiffening plate by two upper pins, the internal mounting holes and the external mounting holes. The ultrasonic sensor is installed at the bottom of the waterproof chamber. The waterproof chamber is equipped with a power conversion module and a wireless transmission terminal. A power supply line is connected to the power conversion module. The power supply line passes through the neck section, the bend section, the insertion section and the column and is connected to the waterproof interface.

[0007] Furthermore, the column is installed via a flange in the end area of ​​the drainage ditch, the low-lying area, or the area within the embankment of the gas station's tank area, and a concrete foundation is provided between the column and the ground of the gas station's tank area.

[0008] Furthermore, a grounding lead is welded and fixed to the periphery of the column, and a lightning protection and anti-static grounding network is provided at the oil tank area of ​​the gas station. The grounding lead is connected to the lightning protection and anti-static grounding network through a down conductor.

[0009] Furthermore, the concrete foundation covers the flange and the bottom area of ​​the column, and the grounding lead and waterproof connector are both located above the concrete foundation.

[0010] Furthermore, the bottom of the waterproof compartment is provided with a circular bottom support edge, and the detection end of the ultrasonic sensor is installed on the bottom support edge, forming a waterproof enclosure between the bottom of the waterproof compartment and the bottom support edge.

[0011] Furthermore, the connecting lug is disposed between the turning section and the necking section, and the connecting lug is provided with a pin hole that mates with the lower pin.

[0012] Furthermore, a sealing groove is provided at the inner end of the elbow section, and a sealing gasket is fixed in the sealing groove. The insertion section is interference-fitted with the elbow section through the sealing gasket.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the combination of a column, a waterproof chamber, and an ultrasonic sensor, can monitor the water level in the oil tank area in real time. Data is transmitted wirelessly using a non-contact ultrasonic ranging principle, ensuring the sensor does not directly contact the water. This fundamentally avoids contamination, adhesion, and corrosion of the sensor head by oil and impurities, guaranteeing the long-term stability and reliability of the monitoring data. The device can be seamlessly integrated into the station's monitoring system, enabling continuous automatic water level monitoring. Once the water level exceeds a preset threshold, an alarm is immediately triggered, providing valuable time for management personnel to take emergency measures such as activating the forced drainage pump and evacuating personnel. This transforms the traditional "passive discovery" management model into an intelligent "proactive early warning" safety management model, improving the safety of the gas station's oil tank area.

[0014] 2. This utility model, through the design of the bent section at the top of the column and the insertion section on the waterproof compartment, allows both to extend and retract to adjust the distance between themselves and the column, thereby adjusting the position of the waterproof compartment. The connecting edge allows for fastening between the two, facilitating the initial adjustment of the ultrasonic sensor's position. This avoids the problem of poor ultrasonic sensor detection area caused by the inability to adjust after the column is installed, especially after the concrete has hardened. It ensures that the sensor is aligned with the actual low point or key drainage path in the tank area, avoiding data distortion caused by installation position deviation.

[0015] 3. This utility model provides comprehensive physical protection for the ultrasonic sensor through the design of the bending section on the column, which can effectively resist sun exposure, rain and wind erosion. In particular, the connection point between the bending section and the waterproof shell forms a natural rainproof eave, which can prevent rainwater from flowing directly into the joint between the waterproof shell and the sensor along the column, greatly improving the sealing and waterproof level and long-term durability of the device.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
