The utility model relates to a test device that is used for measuring the water-resistant performance and the water penetration performance of the under-water facilities, which is characterized in that both ends of a tubular high-pressure cavity are fixedly connected with a flange; an end cover is concentrically and fixedly connected with the flange; an end cap is concentrically and fixedly connected with the end cover; a hydraulic element high-pressure pump is communicated with the inner cavity of the tubular high-pressure cavity after being serially connected with a high pressure valve and a high pressure pipe; a water pressure meter is communicated with the inner cavity of the tubular high-pressure cavity; the centers of the end cover and the end cap are respectively provided with a through hole that leads out a test cable through a sealing element; the axial length of the inner cavity of the tubular high-pressure cavity is more than or equal to 105 m; the area of the cross section of the inner cavity is more than or equal to three times of the cross section area of the test part. The test device has the advantages that after the data such as the water-resistant performance and the water penetration performance of the test cable and the under-water facilities is tested, scientific evidence is supplied for the research, design, manufacturing, repairing and improvement of the cable and the under-water facilities.

Description

Sea cable and the water pressure resistance of underwater facility and the test unit of permeability performance
Technical field
The utility model relates to a kind of test unit that the water pressure resistance test and the permeability performance of extra large cable and underwater facility thereof are tested.
Background technology
All are referred to as submarine communication cable, submarine communication cable, sea electric power cable and the sea floor optoelectronic composite sea cable of extra large cable and supporting with it all kinds of take-off connections under water, straight-through, underwater facility such as active or passive relay amplifier under water, all laying installations and be operated in the sightless seabed of naked eyes, constantly bearing seawater hydraulic pressure, its hydraulic pressure resistance performance is one of important indicator of functional reliability.The destruction of these extra large cables and underwater facility also can be subjected to that earthquake, anchor draw etc. nature and human factor, in case damaged or fracture, under hydraulic action, seawater can coastal cable and the axial two ends infiltration of underwater facility, enlarges the fault face, increases maintenance cost.To the water pressure resistance of extra large cable and underwater facility thereof, water permeability resistance can have relatively high expectations, but also lack the correlation test device that it is carried out the analog operation state at present.
Summary of the invention
In order to fill up at present extra large cable and underwater facility thereof are lacked the water pressure resistance of analog operation state and the blank of permeability performance test, the utility model provides the water pressure resistance of a kind of extra large cable and underwater facility thereof and the test unit of permeability performance, in order to measuring the water pressure resistance alone or in combination and the permeability performance of extra large cable and underwater facility thereof, and can carry out verification experimental verification to design, selection, technology manufacturing, laying installation and the maintenanceability of extra large cable and underwater facility thereof.
The technical scheme that its technical matters that solves the utility model adopts is: the water pressure resistance of a kind of extra large cable and underwater facility thereof and permeability performance test unit, form by tubular high pressure chest, flange, end cap, end cap, water pressure gauge, high-voltage tube, hydraulic part high-pressure pump and high-pressure valve, fixedly connected with flange in the two ends that it is characterized in that tubular high pressure chest, end cap is fixedlyed connected with flange is concentric, end cap is fixedlyed connected with end cap is concentric, the hydraulic part high-pressure pump communicates with the inner chamber of tubular high pressure chest after high-pressure valve and high-voltage tube serial connection, and water pressure gauge communicates with the inner chamber of tubular high pressure chest; The center of end cap and end cap has one to draw the through hole of tested extra large cable by seal; Inner chamber axial length 〉=105 of tubular high pressure chest meter, more than 3 times of the cross-sectional area of this inner chamber 〉=unit under test cross-sectional area.
The beneficial effects of the utility model are to carry out the water pressure resistance and the permeability performance test of analog operation state to extra large cable and underwater facility thereof, filled up the blank of this test unit, for design, manufacturing, application, maintenance, the improvement of extra large cable and underwater facility thereof provides scientific basis.
