Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas storage tank safety monitoring, in particular to an oil and gas storage tank liquid level intelligent monitoring and alarm system. Background Art

[0002] In the petroleum and chemical industries, oil and gas storage tanks are crucial equipment for storing liquid petroleum products. Because these tanks typically hold large volumes and pose high risks, poor level management can lead to spills and leaks, causing not only economic losses but also serious threats to the environment and personnel safety. Traditional level monitoring methods rely on manual inspections or simple mechanical float level gauges. These methods suffer from low accuracy, slow response, and the inability to monitor remotely, making them incapable of meeting the requirements of modern industry for safe production and intelligent management. Utility Model Content

[0003] The technical problems to be solved by the utility model are: 1) low monitoring accuracy: traditional liquid level gauges are easily affected by environmental factors, and the monitoring results have large errors;

[0004] 2) Slow response: The manual inspection cycle is long and abnormal liquid levels cannot be detected in time;

[0005] 3) Unable to remotely monitor: Traditional methods cannot achieve remote data collection and monitoring, resulting in low management efficiency;

[0006] 4) Single alarm method: lack of intuitive sound and light alarm device, and the alarm effect is not ideal.

[0007] To solve the above technical problems, the present invention provides a technical solution: an intelligent monitoring and alarm system for the liquid level of oil and gas storage tanks, comprising:

[0008] The tank body stores oil, and the top two ends of the tank body are respectively provided with a liquid inlet and a liquid outlet, and a monitoring alarm is installed between the liquid inlet and the liquid outlet;

[0009] Monitoring alarm, the monitoring alarm consists of a warning light, a horn, a float, a connecting rod, a connecting rod limit frame, a displacement sensor receiving end, a main control device, a power supply unit, and a displacement sensor sending end. The internal space of the monitoring alarm is divided into two parts by a vertical partition. The left side is the measurement area and the right side is the main control area. There is an opening at the bottom of the measurement area. A float slightly larger than the opening is set below the opening. The float floats on the oil liquid surface. A connecting rod is connected to the upper end of the float. The connecting rod is limited by multiple connecting rod limit frames fixed on the rear wall of the monitoring alarm. Since the float specification is larger than the bottom opening of the measurement area, the float cannot enter the monitoring alarm. The bottom opening of the measuring area is the upper limit position of the float movement. A displacement sensor emitting end is provided at the upper end of the connecting rod. A plurality of displacement sensor receiving ends matching the displacement sensor emitting end are fixed equidistantly from top to bottom on the inner wall of the monitoring alarm. A main control device is provided in the main control area. The main control device is mainly composed of a PCB board equipped with a wireless signal transceiver, a CPU main control chip, and an auxiliary control circuit. A warning light and a speaker are provided at the upper end of the main control device. The warning light and the speaker form a set of sound and light alarm devices. The main control device is connected to the warning light, the speaker, the displacement sensor receiving end, and the displacement sensor emitting end through signal lines to realize overall electrical control.

[0010] The displacement sensor sending end sends a signal to the displacement sensor receiving end corresponding to the horizontal position. Since the height positions of the displacement sensor receiving ends are different, the displacement sensor receiving end that receives the signal transmits its position data to the main control device through the signal line. After receiving the signal, the main control device compares and analyzes it according to the preset liquid level threshold to determine whether the liquid level exceeds the limit; if the liquid level exceeds the limit, the sound and light alarm device is controlled to activate the alarm.

[0011] The advantages of this utility model over the existing technology are: 1) High-precision monitoring: the technical solution of combining float-type liquid level detection and high-precision displacement sensor is adopted, which greatly improves the accuracy and reliability of liquid level monitoring;

[0012] 2) Real-time response: The system can monitor liquid level changes in real time and immediately trigger an alarm when the liquid level is abnormal, effectively shortening the response time;

[0013] 3) Remote monitoring: Through wireless signal transceiver, remote data collection and monitoring of tank liquid level are realized, improving management efficiency;

[0014] 4) Multiple alarm modes: Combined with sound and light alarm devices, it provides an intuitive and effective alarm mode to ensure that attention can be drawn and measures can be taken in time when the liquid level is abnormal.

[0015] Furthermore, the bottom of the tank is equipped with a plurality of matching bases.

[0016] Furthermore, an opening is provided on the top of the tank body, and the opening is communicated with the bottom opening of the monitoring alarm.

[0017] Furthermore, one side of the main control device is connected to a matching power supply unit via a power cord. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, the structural features of the components of this product are:

[0026] 1 tank 1

[0027] The tank body 1 is cylindrical or similar in shape and is made of corrosion-resistant materials such as stainless steel or reinforced plastic to meet the storage needs of the oil 3. An opening is provided at the top for installing the monitoring alarm 2 and ensuring communication between the inside and outside of the tank. The bottom is equipped with multiple matching bases 101 to stably support the tank body and prevent sliding. As a storage container for the oil 3, it protects the oil from the external environment and provides an installation platform for the monitoring alarm 2. The tank body 1 is connected to the base 101 by bolts or other fasteners to ensure a stable installation. The monitoring alarm 2 is connected to the top opening of the tank body through a flange or other sealing interface to form a sealing system.

[0028] 2 Monitoring alarm 2

[0029] The interior of the monitoring alarm 2 is divided into a measurement area and a main control area by a vertical partition. The bottom of the measurement area has an opening that allows the float 203 to float up and down. The float 203 is connected to the displacement sensor output terminal 209 via a connecting rod 204. The connecting rod 204 is supported and limited by a connecting rod limiter 205, ensuring stable movement of the float 203 and connecting rod 204. The main control area houses a main control unit 207, which includes a PCB, a CPU, auxiliary control circuitry, a warning light 201, and a speaker 202. The monitoring alarm 2 is responsible for real-time monitoring of the oil level in the tank and issuing an alarm when the level reaches a preset threshold. Specifically, the float 203 floats up and down with the liquid level, driving the displacement sensor output terminal 209 via the connecting rod 204. The displacement sensor receiving terminal 206 receives the signal and transmits it to the main control unit 207. The main control unit 207 processes the data and determines whether the liquid level exceeds the limit. If so, it activates the warning light 201 and speaker 202. The float 203 is rigidly connected to the displacement sensor output end 209 via a connecting rod 204. The connecting rod 204 is limited in position by a connecting rod limiter 205 via a hinged or sliding mechanism. The displacement sensor receiving end 206 is mounted on the inner wall of the monitoring alarm 2 via a fixed bracket and is connected to the main control unit 207 via a signal cable. The warning light 201 and speaker 202 are mounted directly above the main control unit 207 and are also connected via signal cables. The power supply unit 208 is connected to the main control unit 207 via a power cable to provide the power required by the system.

[0030] Example 2

[0031] Based on the first embodiment, Figures 1 to 4 As shown, the overall working principle is: when the oil 3 changes in the tank body 1, the float 203 floats up and down with the change of the liquid level. The movement of the float 203 is converted into horizontal movement of the displacement sensor sending end 209 through the connecting rod 204. The displacement sensor receiving end 206 determines the position of the float 203 based on the received signal, and transmits the position data to the main control device 207 through the signal line. The CPU main control chip built into the main control device 207 processes this data and compares and analyzes it with the preset liquid level threshold. If the liquid level reaches or exceeds the preset upper or lower limit threshold, the main control device 207 controls the warning light 201 to flash and the speaker 202 to sound an alarm through the signal line to remind the staff to pay attention and take corresponding safety measures.

[0032] Example 3

[0033] Based on the second embodiment, Figures 1 to 4As shown, in the specific implementation, first select the appropriate monitoring alarm 2 model according to the size of the tank body 1 and the liquid level monitoring requirements, and ensure that its installation interface matches the opening on the top of the tank body. Then, install the monitoring alarm 2 on the top of the tank body through a flange or other sealing interface to ensure that the inside and outside of the tank body are connected and well sealed. Next, debug and calibrate the monitoring alarm 2, set the correct liquid level threshold, and check whether the connections of each component are firm and reliable. Finally, connect the power supply unit 208 to the power supply, start the system and perform actual operation tests to verify its monitoring accuracy and the reliability of the alarm function. During operation, regularly check and maintain the various components of the monitoring alarm 2 to ensure its long-term stable operation.
