Description

Technical Field

[0001] The present invention belongs to the technical field of storage tank measurement, and in particular relates to a device and method for measuring the wrinkle capacity of a film tank. Background Art

[0002] To meet various energy needs and replace traditional energy sources, the development and utilization of green energy is urgently needed to promote the implementation of sustainable development strategies. Liquefied Natural Gas (LNG), as a clean and efficient energy source, is gaining increasing favor worldwide. Many countries have listed LNG as their preferred fuel, and the proportion of natural gas in their energy supply is rapidly increasing. LNG membrane tanks are a new type of LNG storage tank. Currently, nearly 100 land-based LNG membrane tanks have been built worldwide. Compared with conventional 9% nickel steel full-containment storage tanks, membrane tank structures offer advantages such as compact design, low unit cost, shortened construction period, and significant energy savings.

[0003] The main shielding membrane of the membrane tank is made of 304L stainless steel corrugated plate with a thickness of 1.2mm. The corrugated plate has two sizes of cross-corrugated wrinkles, and the corrugated plates are connected by lap welding. A single membrane tank with a capacity of 220,000 cubic meters has more than 8,000 corrugated plates. Their complex shape makes it difficult to measure quickly and accurately, which has a great impact on the accuracy of the overall membrane tank volume measurement. Summary of the Invention

By sliding the telescopic rod left and right, the cross-sectional width of the corrugated plate is measured using the cross-sectional width, and by sliding the cross-sectional height up and down, the vertical rod is used to measure the cross-sectional height of the corrugated plate. Then, the three radius measuring structures are used to measure the radii of the three arc segments of the cross-sectional area.

[0047] ④ Calculate the number of intersection nodes between the horizontal corrugated plate and the vertical corrugated plate = Q1×Q2;

[0048] ⑤ If A1 < A2, the volume of each node's intersection and overlap is the volume occupied by the transverse corrugated plate. The volume occupied by the transverse corrugated plate is calculated as: A1 × the width of the vertical corrugated plate × (Q1 × Q2), which is obtained by measuring in step ②;

[0049] ⑥ The volume deducted after the horizontal corrugated plate and the vertical corrugated plate intersect is: (T1+T2)-[A1×width of the vertical corrugated plate×(Q1×Q2)].

The upper end of the measuring rod 52 extends out of the mounting block 51 and a top plate 523 is provided at the end. A reset spring 522 is provided on the measuring rod 52 located between the top plate 523 and the mounting block 51.
