The length of the small cabin of the floating body is matched with the length of the large cabin, and the width and the height of the small cabin of the floating body are smaller than those of the large cabin; the left cargo hold ballast tank and the right cargo hold ballast tank have the same volume and are arranged at the same height, and the middle height of the left cargo hold ballast tank is fixedly provided with a channel steel-shaped buckle used for ensuring the middle limit of a communicating pipe. Therefore, the ballast water in the large tank is mutually transferred left and right through the communicating pipe, the duplex blind flange and the switch valve, and the ballast water in the left and right ballast tanks is also transferred to be mutually transferred left and right through the small floating body tank on the water surface of the ballast water of the large tank, and the small floating body tank floats on the water surface of the ballast water of the large tank, so that the left and right transfer of the left and right small floating body tanks is transferred to the other side through the higher small floating body tank, and the switch valve is arranged on the communicating pipe for communicating the left small floating body tank with the right small floating body tank.
The invention also provides a technical scheme that the method for realizing the inclination test by adopting the ship ballast tank left-right mutual refuting system comprises the following steps: starting a ballast pump connected with the right ballast water main pipe, and opening a third duplex blind flange and a third switch valve to realize that the ballast pump enters water into a ballast tank of the right cargo tank; and then starting a ballast pump connected with the left ballast water main pipe, closing the third duplex blind flange and the third switch valve, and opening the first duplex blind flange, the first switch valve, the second duplex blind flange and the second switch valve, so as to realize the transfer of the ballast water of the right cargo tank ballast tank to the left cargo tank ballast tank.
The invention has the advantages and beneficial effects that: the ballast water in the large tank is adjusted and refuted left and right through the communicating pipe, the duplex blind flange and the switch valve, and the ballast water in the left and right ballast tanks is also adjusted and refuted left and right through the small floating body tank on the water surface of the ballast water of the large tank, and because the small floating body tank floats on the water surface of the ballast water of the large tank, the left and right sides of the small floating body tank are refuted and refuted to the other side through the higher small floating body tank, the switch valve is arranged on the communicating pipe for communicating the left small floating body tank and the right small floating body tank, the switch valve is started when the refuted, and the energy consumption of the ballast pump is reduced by utilizing the difference of the gravitational potential energy due to the difference of the heights of the left and right small floating body tanks, so that the requirements of energy conservation and consumption reduction are met. When the inclination test is carried out, the ballast pump on the ship is utilized, the necessary duplex blind flange and valve members are opened and closed, so that the ballast water pipelines of the left ballast tank and the right ballast tank can be communicated, the ballast water in the tanks can be mutually adjusted and refuted as required, the ship is in an inclined state required by the test instead of an iron block, and the relevant test data can be quickly and effectively obtained, so that the safer and more efficient inclination test method is formed.
