[0002] With the continuous progress of lean shipbuilding and modular shipbuilding, the requirements for hull-outfitting-painting integration are getting higher and higher. The installation of liquid level gauges has always been a difficult problem. The liquid level gauges are made of glass. Brackets are arranged at the upper and lower ends of the liquid level gauges, and seat plate flanges are arranged at the ends of the brackets for installation. The liquid level gauges are installed on the bulkhead through the seat plate flanges. Since there are many liquid level gauges on the ship and their lengths are different, the distances between two seat plate flanges are also different. Therefore, the liquid level gauges are usually installed after actual calibration in the later dock stage. However, it is easy to damage the paint of the cabin, which brings inconvenience to the integrity of the cabin and affects the airtightness and strength inspection of the cabin. Thus, to solve the above problems, in the prior stage of the prior art, the seat plate flanges of the liquid level gauges are pre-installed on the bulkhead, and all are pre-installed by the way of manual scribing. Not only the positioning is inaccurate, but also the operation is cumbersome and the installation is very inconvenient. Content of the Utility Model
