Description

Technical Field

[0001] The utility model relates to the technical field of seawater pipelines, in particular to an anti-icing structure for the seawater pipelines of polar navigation ships. Background Technique

[0002] For general ships, seawater from the outside is introduced into the pipelines inside the ship through a seawater tank for important purposes such as cooling and fire fighting. For polar navigation ships, there are a large number of floating icebergs on the sea surface. If these icebergs enter the pipelines inside the ship through the ice water tank, it will cause major safety hazards.

[0003] When a ship is navigating in polar regions, seawater is pumped into the seawater tank through a pump body for subsequent cooling. The seawater pumped into the seawater tank contains broken ice. The broken ice in the seawater is processed by heating. However, the existing device cannot mix the seawater when processing the broken ice in the seawater, thereby reducing the efficiency of the broken ice processing of the device.

[0004] Therefore, we propose an anti-icing structure for the seawater pipelines of polar navigation ships to solve the problems raised above. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-icing structure for the seawater pipelines of polar navigation ships, including a seawater tank. On the opposite sides of the top and bottom of the inner cavity of the seawater tank, a fixed frame is fixedly installed together. Near the bottom on the other side of the inner cavity of the seawater tank, a rectangular groove is fixedly installed. A pump body is installed in the inner cavity of the rectangular groove. The water inlet end of the pump body penetrates through the bottom of the inner cavity of the rectangular groove. The water outlet end of the pump body is fixedly installed with a water inlet pipe, and one end of the water inlet pipe penetrates through the inner cavity of the seawater tank and extends into the inner cavity of the fixed frame. A mixing mechanism is arranged in the inner cavity of the fixed frame. A pressure relief mechanism is arranged near one side of the top of the seawater tank;

[0007] The mixing mechanism includes a fixed groove fixedly installed at the middle position of the top of the seawater tank and a driving motor fixedly installed at the top of the inner cavity of the fixed groove. A main mixing shaft is fixedly installed at the shaft end of the power output shaft of the driving motor. The bottom end of the main mixing shaft movably penetrates through the top of the inner cavity of the seawater tank and is rotatably connected to the bottom of the inner cavity of the seawater tank.

[0008] Preferably, a protective groove is rotatably connected to the outer periphery of the main mixing shaft near the top, and the top of the protective groove is fixedly connected to the inner cavity top of the seawater tank. A driving bevel gear is fixedly sleeved on the outer periphery of the main mixing shaft near the top, and the driving bevel gear is located in the inner cavity of the protective groove. Driven bevel gears are meshed on both sides of the driving bevel gear. A secondary mixing shaft is fixedly installed on the side of each driven bevel gear away from each other. The ends of the secondary mixing shafts away from each other respectively pass through the inner cavity of the adjacent protective groove movably and are rotatably connected to the inner cavity side wall of the fixed frame. Secondary mixing blades are fixedly sleeved on the outer peripheries of the secondary mixing shafts.

[0009] Preferably, a water outlet pipe is inserted into one side of the seawater tank near the bottom. Heating blocks are fixedly installed on both sides of the inner cavity bottom of the seawater tank near the front and back. The heating blocks are all located outside the fixed frame.
