A watertight test device for welded seams of outer bottom plate through-cabin parts of hull

Abstract

The present disclosure provides a watertight test device for the weld seam of the outer bottom plate of the hull, which includes a test cover, an adjustment support assembly and a hydraulic test assembly. The lower end of the test cover is fixedly connected to the upper end of the adjustment support assembly. The upper end of the test cover is attached to the watertight test place, and the hydraulic test assembly is connected to the test cover; the beneficial effect of the present disclosure is that the air in the test cover can be safely and quickly removed through the exhaust ball valve, ensuring that the medium and the tested welding Good contact with the seam; the drainage ball valve not only undertakes the function of water injection, but also opens the ball valve after the test to quickly discharge the test water. By setting the coarse adjustment component, that is, using one or more superimposed support piers, which are coaxial and vertically placed directly under the weld to be tested, it avoids the flexibility of use due to the different heights of the hull baseline and the narrow space. Effect. By setting the fine-tuning component, the height fine-tuning can be carried out, which increases the operability of the test.

Description

technical field [0001] The present disclosure relates to the field of ship testing, in particular to a watertight test device for weld seams of hull outer bottom plate through-cabin parts. Background technique [0002] During the construction of a certain type of ship, the tightness test is required after the structural welding, outfitting and non-destructive testing are completed for the tightness of the cabin, so as to check the tightness quality of the welded seam after welding. For example, after the pipes of the log and depth sounder equipment pass through the outer bottom plate of the hull and are welded, the watertight test of this part needs to be carried out, and the test pressure process requirement of this part is 0.2 Mpa; The pressure requirement for the cabin airtightness test of the log cabin and the depth sounder cabin is 0.02Mpa; for the sake of safety, the watertight test cannot be directly carried out on the log cabin and the depth sounder cabin as a whole ...

Problems solved by technology

For example, after the pipes of the log and depth sounder equipment pass through the outer bottom plate of the hull and are welded, the watertight test of this part needs to be carried out, and the test pressure process requirement of this part is 0.2 Mpa; The pressure requirement for the cabin airtightness test of the log cabin and the depth sounder cabin is 0.02Mpa; for the sake of safety, the watertight test cannot be directly carried out on the log cabin and the depth sounder cabin as a whole to check the tightness of these parts. The traditional welding The seam watertight test device cannot achieve the above detection results, so it is necessary to design a watertight test device for the weld seam of the outer bottom plate of the hull with a simple structure, low cost, and easy operation in combination with the actual situation on site.
