Description

Technical Field

[0001] The utility model relates to the technical field of ship oil product spill prevention, and more specifically, to a port oil product loading and unloading spill prevention monitoring system. Background Art

[0002] With the vigorous development of China's economy, the amount of imported oil has increased year by year, with an average of millions of tons of oil entering and leaving ports every day. The demand for oil transportation has increased significantly year by year, and oil pollution has become one of the main sources of marine pollution. About 92% of oil spills occur in inner ports, mostly caused by human operations. Oil pollution has become one of the main pollutants in coastal and offshore areas. In recent years, there have been several oil leakage or overflow accidents in my country, causing heavy losses to the country and enterprises. In the process of loading and unloading oil products from oil tankers, there is no safe and effective equipment to prevent oil leakage in waterway oil depots. The petrochemical terminal has time requirements for loading and unloading oil. The loading and unloading time of the smallest tonnage oil tanker is 3-5 hours, and the loading and unloading time of large tonnage oil tankers is more than 10 hours. In the absence of automated overflow monitoring devices, staff are required to measure the liquid level at the oil tanker measuring port at all times. A staff member needs to pay attention to multiple oil tankers at the same time, which is a hard job for the staff. Moreover, this overflow prevention method that relies on real-time observation by staff not only occupies human resources, but also harms the health of on-site personnel, is inefficient, and cannot completely guarantee that there will be no oil spill accidents, resulting in waste of resources and environmental pollution, and has certain safety hazards.

[0003] Therefore, it is particularly important to prevent oil spill accidents during port loading and unloading of oil products, and it is necessary to carry out automated monitoring measures to prevent oil spills during port loading and unloading of oil products. Utility Model Content

[0004] The purpose of the utility model is to overcome the current lack of effective anti-oil spill monitoring measures during the loading and unloading of oil tankers at the wharf, and to provide a port oil product loading and unloading anti-oil spill monitoring system. The utility model can predict and identify the oil spill risk of oil tankers in advance, effectively improve the risk control level of waterway loading operations, and at the same time improve the intelligence level of oil depots and reduce the labor intensity of employees.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A port oil loading and unloading anti-overflow monitoring system comprises a liquid level acquisition device for obtaining the liquid level of an oil tanker's oil tanker, an anti-overflow monitoring device connected to the liquid level acquisition device and configured at a dock, a master control device connected to the anti-overflow monitoring device and used for remote operation, and a bypass switch whose input end and output end are respectively connected to the master control device and the liquid level acquisition device.

[0007] It should be noted that the utility model obtains the liquid level of each oil tanker on the oil tanker through the liquid level acquisition device arranged on the oil tanker, and the overflow prevention monitoring device arranged on the dock makes it convenient for the operating personnel on the dock to obtain the liquid level changes and overflow conditions during the loading and unloading process of each oil tanker on the oil tanker. At the same time, the master control device can output corresponding control instructions after processing and analyzing the liquid level change and overflow condition data obtained by the overflow prevention monitoring device. When the oil product exceeds the set liquid level threshold in the quantitative loading system connected to the master control device, a safety interlock can be realized to disconnect the oil product loading and unloading process, prevent the occurrence of oil spill accidents on the oil tanker, ensure the safety of the oil tanker during the loading and unloading process, and transform from passive disposal of emergency accidents to active disposal. Actively prevent risks, and "human defense" becomes "technical defense"; in addition, due to the large number of oil tankers' oil tankers, a bypass switch is added to connect the input and output ends to the master control device and the liquid level collection device respectively. The master control device can selectively open and close the liquid level collection devices corresponding to different oil tanks according to the input settings, so that the corresponding number of liquid level detection devices can be opened according to the number of oil tankers, or when an oil tank reaches the liquid level threshold limit in advance and other oil tanks still need to be filled, the corresponding liquid level collection device can be turned off through the bypass switch, and the oil transportation passage of the corresponding oil tank is closed, while other oil tanks can continue to be filled, thereby realizing selective monitoring and targeted control of different oil tanks, which can meet more application scenarios.

[0008] Furthermore, the liquid level acquisition device includes a liquid level detection circuit, a plurality of liquid level sensors connected to the input end of the liquid level detection circuit and used to detect the liquid level of each oil tank, and a first alarm connected to the output end of the liquid level detection circuit. The output end of the liquid level detection circuit is also connected to the overflow prevention monitoring device.

[0009] Furthermore, it also includes a battery connected to the liquid level detection circuit and used for power supply.

[0010] Furthermore, the battery is a lithium battery, a nickel-metal hydride battery or a nickel-cadmium battery. The lithium battery, the nickel-metal hydride battery or the nickel-cadmium battery include but are not limited to rechargeable or non-rechargeable types.

[0011] Furthermore, the liquid level detection circuit is connected to the overflow prevention monitoring device via wireless communication.

[0012] It should be noted that the liquid level detection circuit is powered by a battery and detects the liquid level in the oil tanker through a liquid level sensor. When the liquid level reaches the preset alarm position, an alarm is sounded through the first alarm. Since the oil tanker, the dock and the control area are often separated far apart during the loading and unloading of oil products at the port, wireless communication is the most appropriate method. The liquid level acquisition device is placed at the dock berth when not enabled. When enabled, the enabled liquid level acquisition device is fixed to each oil tanker metering port of the oil tanker, and the liquid level sensor is extended into the metering port of the corresponding oil tanker, and the liquid level alarm limit is adjusted. The oil tanker liquid level is detected in real time during filling. When the oil level exceeds the safety limit, the liquid level sensor detects the liquid, and the liquid level sensor outputs an alarm signal to the liquid level detection circuit. The liquid level detection circuit immediately sounds an alarm through the first alarm to remind the personnel on the oil tanker to take corresponding measures. At the same time, the liquid level detection circuit transmits the alarm signal to the overflow prevention monitoring device at the dock berth through wireless communication, so as to realize real-time monitoring of oil tanker loading and unloading.

[0013] Furthermore, the overflow prevention monitoring device includes an overflow prevention control circuit, and a second alarm and a first display connected to the output end of the overflow prevention control circuit. The output end of the overflow prevention control circuit is also connected to the master control device.

[0014] Furthermore, the overflow prevention control circuit is connected to the master control device via wireless communication.

[0015] It should be noted that the overflow prevention control circuit receives the oil tank alarm information transmitted by the liquid level detection circuit through wireless communication, displays the corresponding tank alarm information through the first display, and sounds an alarm at the dock berth through the second alarm to remind the dock berth personnel to take corresponding measures, and at the same time transmits the alarm information to the main control device through wireless communication.

[0016] Furthermore, the master control device includes a control circuit, a second display and a third alarm connected to the output end of the control circuit, and a control panel connected to the input end of the control circuit, and the output end of the control circuit is respectively connected to the overflow prevention monitoring device and the bypass switch.

[0017] Furthermore, the control circuit is connected to the bypass switch via wireless communication.

[0018] It should be noted that after receiving the position alarm information through wireless communication, the master control device displays the liquid level information of each oil tanker through the second display, and alarms in the master control room through the third alarm, reminding the personnel in the master control room to adopt corresponding measures to prevent oil spill accidents from occurring on oil tankers and ensure the safety of oil tankers during loading and unloading; in addition, the control panel can also output automatic control instructions to the bypass switch to specifically open or close the liquid level collection devices of different oil tanks.

[0019] Furthermore, the first alarm, the second alarm and the third alarm are all sound and light alarms.

[0020] It should be noted that, since the oil tankers, docks and control room areas are often separated far apart during oil loading and unloading at ports, the liquid level collection device on the oil tanker, the overflow prevention monitoring device on the dock, and the master control device in the control room area are respectively provided with corresponding alarms. In order to be able to promptly remind the corresponding site personnel to take corresponding measures as soon as possible, the sound and light alarm is more effective; the wireless communication means in the utility model include but are not limited to LoRa, WiFi, Bluetooth, etc.; the realization principle of the liquid level sensor in the utility model includes but is not limited to photoelectric, piezoelectric, tuning fork, radio frequency admittance, radar and other principles.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The utility model obtains the liquid level of each oil tanker on the oil tanker through a liquid level acquisition device arranged on the oil tanker, and facilitates the operators on the dock to obtain the liquid level changes and overflow conditions of each oil tanker during the loading and unloading process through an overflow prevention monitoring device arranged on the dock. At the same time, the master control device can output corresponding control instructions after processing and analyzing the liquid level change and overflow condition data obtained by the overflow prevention monitoring device. The master control device is externally connected to the quantitative loading system. When the oil exceeds the set liquid level threshold, a safety interlock can be implemented to disconnect the oil loading and unloading process, prevent the occurrence of oil spill accidents on the oil tanker, and ensure the safety of the oil tanker during the loading and unloading process, thereby transforming from passive handling of emergency accidents to active prevention of risks, and changing "human defense" to "technical defense".

[0023] (2) Due to the large number of oil tankers, the utility model adds a bypass switch whose input and output ends are respectively connected to the master control device and the liquid level acquisition device. The master control device can selectively open and close the liquid level acquisition devices corresponding to different oil tanks according to the input settings, so that the corresponding number of liquid level detection devices can be opened according to the number of oil tanks. Or when a certain oil tank reaches the liquid level threshold limit in advance, while other oil tanks still need to be filled, the corresponding liquid level acquisition device can be turned off through the bypass switch, and the oil transportation path of the corresponding oil tank is closed, while other oil tanks can continue to be filled, thereby realizing selective monitoring and targeted control of different oil tanks, which can meet more application scenarios.

At the same time, the master control device 3 obtains the liquid level change and overflow condition data after processing and analyzing by the overflow prevention monitoring device 2, and can output corresponding control instructions. When the master control device 3 is externally connected to the quantitative loading system, when the oil exceeds the set liquid level threshold, the safety interlock can be realized, the oil loading and unloading process can be disconnected, and the oil spill accident of the oil tanker can be prevented. The safety of the oil tanker during the loading and unloading process is ensured, and the passive handling of emergency accidents is transformed into active prevention. Risk, "human defense" becomes "technical defense"; in addition, due to the large number of oil tankers' oil tankers, additional input and output ends are connected to the bypass switch 4 of the master control device 3 and the liquid level acquisition device 1 respectively. The master control device 3 can selectively open and close the liquid level acquisition devices 1 corresponding to different oil tanks according to the input settings, so that the corresponding number of liquid level detection devices can be opened according to the number of oil tanks, or when a certain oil tank reaches the liquid level threshold limit in advance, and other oil tanks still need to be filled, the corresponding liquid level acquisition device 1 can be closed through the bypass switch 4, and the oil transportation passage of the corresponding oil tank is closed, and other oil tanks can continue to be filled, thereby realizing selective monitoring and targeted control of different oil tanks, which can meet more application scenarios.

When the liquid level reaches the preset alarm position, an alarm is sounded through the first alarm. Since the oil tanker, the dock and the control area are often separated far apart during the loading and unloading of oil products at the port, wireless communication is the most appropriate method. The liquid level acquisition device 1 is placed at the dock berth when not enabled. When enabled, the enabled liquid level acquisition device 1 is fixed to each oil tanker metering port of the oil tanker, and the liquid level sensor is extended into the metering port of the corresponding oil tanker, and the liquid level alarm limit is adjusted. The oil tanker liquid level is detected in real time during filling. When the oil level exceeds the safety limit, the liquid level sensor detects the liquid, and the liquid level sensor outputs an alarm signal to the liquid level detection circuit. The liquid level detection circuit immediately sounds an alarm through the first alarm to remind the personnel on the oil tanker to take corresponding measures. At the same time, the liquid level detection circuit transmits the alarm signal to the anti-overflow monitoring device 2 at the dock berth through wireless communication, so as to realize real-time monitoring of oil tanker loading and unloading.

The output end of the overflow prevention control circuit is also connected to the main control device 3.

[0038] In this embodiment, the overflow prevention control circuit is connected to the master control device 3 via wireless communication.
