Description

Technical Field

[0001] The utility model relates to the technical field of oil tank liquid level monitoring equipment, in particular to an oil tank liquid level monitoring device. Background Art

[0002] At present, the traditional fuel tank liquid level monitoring system generally adopts manual or semi-manual monitoring methods. The test engineer enters the site and records the lubricating oil level data by observing the tank scale with the naked eye. However, this monitoring method requires a test engineer to enter the test site regularly to record the lubricating oil level in the tank, which undoubtedly causes a lot of waste of manpower and material resources. Moreover, the frequent entry of test engineers into the test site also poses a major danger to the personal safety of test engineers. Therefore, how to realize remote monitoring of the fuel tank liquid level and improve the detection efficiency of the fuel tank liquid level are technical problems that technical personnel in this field need to solve at present. In addition, the current liquid level monitoring device generally adopts a fixed assembly method when in use, and the device cannot be quickly disassembled and assembled, which is difficult to meet the corresponding use requirements. To this end, we propose a fuel tank liquid level monitoring device. Utility Model Content

[0018] Automatic detection of the tank liquid level is achieved by means of a radar level meter installed inside the tank 1. The controller 24 can generate historical liquid level information based on multiple receipts of tank liquid level data transmitted by the level meter, and then transmit the liquid level information to the terminal device 25 for staff to observe and analyze. The provided tank liquid level monitoring device does not require staff to personally go to the site to read the tank liquid level, and can realize automatic reading of the tank liquid level, thereby realizing remote monitoring of the tank liquid level and improving the detection efficiency of the tank liquid level.

[0019] In the above scheme, the card plate 15 is an "L"-shaped card plate. By setting the slot 13, the movable slot 14, the card plate 15, the first spring 16, the second spring 17, the latch 18 and the through hole 19 and other structures for use together, the liquid level meter housing 12 can be quickly installed on the mounting seat 11, the operation is simple and convenient, and the equipment can be easily disassembled, thereby improving the effective maintenance efficiency of the equipment and saving the use cost.

The electromagnetic pulse of the radar level meter propagates at the speed of light. When encountering the surface of the measured medium, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse therebetween. The liquid level height is calculated to achieve the purpose of liquid level detection.

At this time, the radar level meter body 2 and the antenna cover 23 extend into the fuel tank 1. The radar level meter body 2 arranged inside the fuel tank 1 realizes automatic detection of the liquid level in the fuel tank 1. The controller 24 can generate historical liquid level information based on the fuel tank level data transmitted by the level meter for multiple times, and then transmit the liquid level information to the terminal device 25 for observation and analysis by the staff. The provided fuel tank level monitoring device does not require the staff to personally go to the site to read the fuel tank level, and can realize automatic reading of the fuel tank level, realize remote monitoring of the fuel tank level, and improve the detection efficiency of the fuel tank level. When the level meter needs to be disassembled for maintenance, the pin 18 is first pulled out of the through hole 19, and then the card plate 16 is manually pushed outward so that the card plate 16 is withdrawn from the slot 13. At this time, the level meter can be disassembled as a whole, achieving the purpose of easy disassembly and assembly, and solving the problem that the current level monitoring equipment is inconvenient to disassemble and use.
