Description

Technical Field

[0001] This utility model relates to the field of density measurement technology, and more specifically, to a density measuring device for oil storage tanks. Background Technology

[0002] Existing technologies for measuring the density of oil storage tanks have several drawbacks, primarily due to the unstable insertion process of the measuring components and the cumbersome installation, fixing, and disassembly of these components. Specifically, existing devices often experience uneven insertion, significant vibration, or instability when the measuring components are inserted due to imperfections in their mechanical structure or unreasonable design. This not only affects measurement accuracy but may also cause wear and tear on the equipment, shortening its service life.

[0003] Furthermore, the installation and disassembly of the measuring components also present certain problems. The existing equipment design relies too heavily on manual operation. Installation requires adjusting and securing multiple components, and disassembly often necessitates multiple manual operations, making the process complex and time-consuming. This design not only increases the workload of operators but also, due to the difficulty of disassembly, may lead to prolonged periods without maintenance or replacement of the measuring equipment, thereby affecting the normal operation of the device and the accuracy of the measurement data.
