Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ship cabin drainage, and particularly discloses a closed ship cabin drainage mechanism. BACKGROUND

[0002] The closed ship cabin refers to a ship body part with a closed structure, for example, an auxiliary engine cabin, which usually adopts a closed structure to improve the safety performance of the ship. In addition, the cabin is also provided with an emergency exit, lifesaving equipment and the like to ensure that the operating personnel can quickly evacuate and escape in an emergency.

[0003] During the use of the ship, due to the leakage of the outer plate, the insufficient water tightness of the hatch cover, the leakage of the pipeline, the leakage of the stuffing box of the tail shaft sleeve and the rudder sleeve, and the condensation of moisture caused by the temperature difference, water will be accumulated at the bottom of the cabin, which is commonly referred to as cabin bottom water. The sources of the cabin bottom water include the water leakage of the mechanical equipment, the leakage of the pipeline, the seepage of the flushing water through the ship shell, the rainwater flowing into the hatch, and the accumulated water caused by the damage of the ship, fire fighting and the like. For the closed auxiliary engine cabin, the domestic water of the whole ship can also be accumulated in the cabin. At present, the closed auxiliary engine cabin is usually provided with a drainage port and a drainage pipeline to drain the water outside. However, during the operation of the ship, the living sundries can cause the drainage port and the drainage pipeline to be blocked to different degrees, and the maintenance personnel usually need to regularly maintain and clean the drainage port and the drainage pipeline to ensure that the water in the bottom cabin is normally drained.

[0004] For the closed auxiliary engine cabin, in order to pursue the safety of the ship and improve the degree of automation, various electronic devices are arranged in the cabin. If the pipeline and the valve in the cabin fail, a large amount of water can easily accumulate in the cabin, especially when the valve fails to leak water due to the blockage of the filter grid in the drainage pipeline. The accumulated water can cause the circuit in the cabin to be short-circuited, affect the normal use of the automatic equipment in the cabin, and even threaten the safety of the ship. Therefore, the inventor provides a closed ship cabin drainage mechanism to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at solving the problem that the bottom of the cabin body is easy to accumulate water when the drainage pipeline of the traditional closed ship cabin is blocked, and the safety of the ship is affected.

[0010] Further, the auxiliary pipe is provided with a fixed column, the guide column is hollow and is sleeved on the fixed column, and a spring is arranged between the top of the fixed column and the inner top of the guide column.

[0011] Further, the piston comprises a connecting portion connected with the guide column, a rigid portion arranged on the outer wall of the connecting portion and in sliding connection with the inner wall of the auxiliary pipe, and an elastic portion arranged on the outer wall of the rigid portion and matched with the through hole.

[0015] Further, the auxiliary pipe is provided with an electromagnet, and the sealing plate is provided with a magnetic block which is magnetically adsorbed with the electromagnet.

[0016] The principle and effect of the scheme are that:

[0017] Compared with the prior art, the auxiliary pipe is arranged on the side wall of the drain pipe, in the normal drain process of the drain pipe, the auxiliary pipe is not used for direct drainage and is used as a backup, and living impurities and the like cannot accumulate in the auxiliary pipe to cause blockage, when the drain pipe is blocked or the water in the cabin is too high, the auxiliary pipe is connected with the drain pipe through the regulator, so that the auxiliary pipe can be used for drainage operation, the drain device in the utility model adopts two control modes of electric control and manual control, can be suitable for different site conditions, can be normally used even in the case of power failure, and the guide column in the utility model adopts a hidden design, and does not affect the overall appearance of the drain structure in the cabin.
