Title:
UNDERWATER CONSTRUCTION EQUIPMENT PRESSURIZATION COMPENSATOR
Document Type and Number:
WIPO Patent Application WO/2020/244135
Kind Code:
A1
Abstract:
The present application provides an underwater construction equipment pressurization compensator, comprising a bladder, a housing, and a pressure member. The bladder is disposed in the housing; an opening is formed on the housing so that the cavity outside the bladder is communicated with the cavity outside the housing; the pressure member is disposed outside the bladder and abuts against the bladder to apply a pressure to the bladder to squeeze the bladder. In the underwater construction equipment pressurization compensator of the present application, an elastic member is provided to apply a pressure to the bladder, so that the liquid in the bladder generates an additional pressure, and thus, the difference between the pressure of the liquid inside the bladder and the pressure of the liquid outside the bladder can be increased, thereby overcoming the shortcoming of small difference between the pressures inside and outside the pressure compensator using only a bladder, and the bladder structure does not have the problem of failure caused by jamming and has high reliability.
