DETAILED DESCRIPTION
[0019] The utility model discloses an embodiment of the utility model will be clearly and completely described below with the drawings in the embodiment of the utility model to the technical scheme in the embodiment of the utility model, obviously, the described embodiment only is a part of embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments that the ordinary skill in the art obtains without making creative labor belong to the range of protection of the utility model.
[0020] Please refer to Figures 1-4 A novel ship stabilizing device, including mounting plate 1, the inside rotation of mounting plate 1 is connected with pendulum 2, the inside rotation of mounting plate 1 is connected with reciprocating pump body 3, the top of reciprocating pump body 3 is fixedly installed with drain pipe 4, the top of drain pipe 4 is fixedly installed with electric control adjustable opening electromagnetic valve 5, the outer surface of drain pipe 4 is fixedly installed with throttle pipe 6, the bottom of reciprocating pump body 3 is fixedly installed with water inlet pipe 7, the bottom of water inlet pipe 7 is provided with water inlet 8, the inside of reciprocating pump body 3 is movably connected with reciprocating pump piston 9, the bottom of reciprocating pump body 3 is fixedly installed with support plate 10, the outer surface of support plate 10 is fixedly installed with hinged block 11, the inside of hinged block 11 is hinged with extension sleeve 12, the outer surface of extension sleeve 12 is sleeved with damping spring 13.
[0021] Specifically, as Figure 3 When the ship roll amplitude is larger, the swing amplitude of pendulum 2 will also increase, to prevent reciprocating pump piston 9 from frequently impacting reciprocating pump body 3, the throttle buffer unit is designed at the tail of reciprocating pump body 3, when reciprocating pump piston 9 exceeds water inlet 8 and drain port, the water in the left cavity of reciprocating pump piston 9 will flow to drain port through throttle pipe 6, because the diameter of throttle pipe 6 is small, therefore, the impact of reciprocating pump piston 9 on reciprocating pump body 3 can be weakened, and reciprocating pump piston 9, extension sleeve 12, extension rod and damping spring 13 can also effectively reduce the impact damage and increase the service life of the device.
[0022] Specifically, as Figure 3As shown, in response to different ship roll of different frequency, the electrically controlled adjustable opening electromagnetic valve 5 installed at the water outlet of the reciprocating pump pump body 3 adjusts the opening size by receiving the analog signal of the controller to adjust the swing frequency of the pendulum 2. When the sensor detects that the ship roll frequency increases, the controller will control the electromagnetic valve to increase its opening, so that the water in the reciprocating pump cavity is quickly discharged. On the contrary, when the ship roll frequency decreases, the controller will control the electromagnetic valve to reduce its opening, so that the water in the reciprocating pump cavity is slowly discharged. In this way, the purpose of controlling the swing frequency of the pendulum 2 is achieved, so that the swing frequency of the pendulum 2 is always equal to the ship roll frequency and the swing direction is opposite, thereby increasing the effect of the device on preventing ship roll.
[0023] In implementation, the following steps are taken:
[0024] 1) When the ship rolls on the sea, the pendulum 2 will deviate in the opposite direction of the ship roll under the action of inertial force;
[0025] 2) Then the ship roll moment is weakened by this method, and the reciprocating pump pump body 3 and the reciprocating pump piston 9 on both sides of the pendulum 2 are also driven to work;
[0026] 3) The reciprocating pump pump body 3 and the reciprocating pump piston 9 can suck water from the bow of the ship and discharge it to the stern of the ship;
[0027] 4) Finally, due to the water suction effect, a vacuum is formed at the bow of the ship, reducing the forward resistance, and on the other hand, the water discharge can also push the ship forward, reducing fuel consumption.
[0028] In summary, the new ship roll reduction device, when the ship rolls on the sea, the pendulum 2 will deviate in the opposite direction of the ship roll under the action of inertial force, which not only weakens the ship roll moment, but also drives the reciprocating pump pump body 3 and the reciprocating pump piston 9 on both sides of the pendulum 2 to work. The reciprocating pump pump body 3 and the reciprocating pump piston 9 can suck water from the bow of the ship and discharge it to the stern of the ship. On the one hand, due to the water suction effect, a vacuum is formed at the bow of the ship, reducing the forward resistance, and on the other hand, the water discharge can also push the ship forward, reducing fuel consumption, thereby effectively reducing the ship roll and converting the ship roll energy into forward power, achieving the purpose of improving the comfort and energy saving of the ship.
