The connection between the hard connection pipe 400 and the seawater main pipe 110 is provided with an isolation valve set for switching between a fixed water path and a floating water path.

In normal use: outboard seawater is taken through a fixed waterway (A branch) where the seawater tank 100 is located, and when the seawater tank 100 is blocked by sludge, an outboard seawater is taken through a floating waterway (B branch); switch between two sets of waterways as required through isolation valves and use, and as the replacement of each other, guarantee the normal of whole outboard sea water intaking, avoid appearing silt and block or the sea water is low excessively high sea water tank 100 can't draw the problem to low sea water tank 100.

The working principle and the using process of the utility model are as follows:

referring to fig. 1, a typical semi-submersible barge consists of a head tower at the head, a tail tower at the tail, ballast tanks at the bottom, etc. The generator compartment is typically located above the safety deck, the pump compartment is typically located at the bottom of the semi-submersible barge, and the sea chest 100 is typically located in the pump compartment at a lower location.

Referring to fig. 2, a simulation diagram of the situation around the low sea chest when the semi-submersible barge is at the maximum sinking depth. The sea chest 100 is located at the bottom of the pump room, i.e. it is also commonly referred to as a low sea chest 100. the sea chest 100 is provided with an opening outboard, which is provided with a suction grid 120. the suction grid 120 is mainly used for coarse filtering of the sucked sea water. The sea chest 100 is connected to a sea main 110, and sea water is supplied to the semi-submersible barge through the sea main 110.

Under normal conditions, as shown in the position of fig. 1, the seawater tank 100 is far from the sea floor, and the sea floor sludge is not sucked by the seawater main pipe 110. When the semi-submersible barge is in operation at the bottom, the seabed sludge may be sucked by the seawater main pipe 110, even submerge the suction grid 120 of the whole seawater tank 100, and at this time, the semi-submersible barge 100 cannot suck clean seawater from the outboard, even is completely blocked by the sludge, which may cause equipment failure and termination of the semi-submersible barge operation in serious cases.

Referring to fig. 3, a simulation of the situation around the high sea chest 100 of the semi-submersible barge at maximum sinking depth is shown. Some designs are improved on the original basis, namely, a high sea chest 100 is arranged above an original low sea chest 100, the problem that the low sea chest 100 is blocked can be solved by using the high sea chest 100 at some times, but the semi-submersible barge draft is uncertain and depends on the sea depth of an operating water area and the hardness of the sea bottom, the operation sinking depth as shown in the figure can cause the high sea chest 100 to be partially exposed out of the water surface, and at the moment, the sea main pipe 110 cannot effectively absorb water (suck air).
