Abstract
The invention discloses an underwater tensile force measurement device, which comprises an overpressure-resistant cylinder assembly, a piston and piston rod assembly, a water-pressure resistant differential pressure/pressure transducer, a liquid, and an external pressure-resistant hydraulic pipeline. Two equal-diameter piston rods of the piston and piston rod assembly respectively pass through a hole in the end portion of the overpressure-resistant cylinder assembly or a center hole in a sealing end cap thereof. Gaps among the above two piston rods and the hole in the end portion of the overpressure-resistant cylinder assembly or the center hole in the sealing end cap thereof are respectively sealed by a seal ring. Gaps among the piston rods of the piston and piston rod assembly and the inner cavity of an overpressure-resistant cylinder are sealed by seal rings. Meanwhile, the inner cavity of the overpressure-resistant cylinder is divided into an upper cavity and a lower cavity. The upper and lower cavities of the overpressure-resistant cylinder, or only one cavity of the overpressure-resistant cylinder, are/is filled with the liquid and are/is connected with the differential pressure/pressure transducer via the external pressure-resistant hydraulic pipeline. The tension force applied on the piston rods is measured by the differential pressure/pressure signal of the differential pressure/pressure transducer. The device is simple in structure, stable, reliable and high in measurement accuracy.
