Abstract

The invention discloses a deepwater pressure-withstanding weighing apparatus. The apparatus includes a testing cabin, a main weighing unit, an auxiliary weighing unit, a data acquisition processing unit, a pressure sensor and a boost pump. The main weighing unit has an elastic holding rack which assumes a special shape shown in the description. The upper end of the elastic holding rack is secured to an object tray, the lower end is secured to a bottom holder of the testing cabin, and the middle section of the middle horizontal part is provided with a deformation sensor. The deformation sensor senses a stress deformation signal sent by the elastic holding rack when the object tray carries a to-be-tested sample. The auxiliary weighing unit has a deformation sensor which senses a stress deformation signal sent by the elastic holding rack when a weight tray carries a counterweight. According to the invention, the apparatus calculates the changes of water density upon boosting by measuring the changes of counterweights in the testing cabin, and weighs the to-be-tested sample on the object tray when the water density inside the testing cabin increases, further acquires the infiltration capacity and volume contraction of the to-be-tested sample inside the testing cabin, and finally determines whether the to-be-tested sample meets requirements.

Description

technical field [0001] The invention relates to a detection device for marine instruments and equipment, in particular to a pressure-resistant weighing detection device for deep-sea instruments and equipment. Background technique [0002] With the development of my country's marine survey, scientific research and deep-sea construction operations, the demand for various deep-water pressure-resistant instruments and equipment continues to increase, and more stringent requirements are put forward for the pressure-resistant inspection of deep-water pressure-resistant instruments and equipment. The testing of deep water pressure-resistant instruments includes the testing of the leakage of the pressure-resistant shell, the water absorption rate of the pressure-resistant hard floating body, and the shrinkage rate of the pressure-resistant soft floating body. During the hydrostatic pressure test, the leakage of the pressure-resistant shell, the water absorption rate of the pressure-...
