Description

Technical Field

[0001] The present invention relates to the technical field of ship tooling parts, and specifically to a tooling part for floating and draining water in a dry dock. Background Technique

[0002] A ship is the general term for various vessels. A ship is a means of transportation that can sail or berth in water areas for transportation or operations. It has different technical performances, equipment, and structural forms according to different usage requirements. A ship is a man-made means of transportation mainly operating in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or canoes. Their general term is ships or vessels. The interior mainly includes accommodation space, support structure, and drainage structure, and has a propulsion system that utilizes external or self-provided energy. The outer shape is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials have been continuously updated with the progress of technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, as well as aluminum, fiberglass, acrylic, and various composite materials.

[0003] Currently, when a general ship is half-floating, water needs to be added to the cargo hold to maintain the floating state. After the half-ship is landed, the water in the cargo hold needs to be drained. However, fresh water resources are scarce in the sea, and generally seawater flushing is mostly used. After long-term use, seawater is likely to cause corrosion to the inner wall of the pipeline. Therefore, a tooling part for floating and draining water in a dry dock is required to facilitate the auxiliary floating and drainage of the half-ship of the ship, and at the same time, it can cooperate with an external water pump to flush the inner wall of the pipeline with fresh water to ensure the service life of the device.

[0039] Working principle: During use, connect the output end of the straight pipe 701 to the output end of an external fresh water pump, and connect the input end of the pump to the fresh water tank. When the external fresh water pump is in a stopped state, the return spring 803 presses the piston 801 against the limit retaining ring 804, the expansion bladder cylinder 1003 contracts, the water passage opening 1006 opens and is unobstructed, and the elbow pipe 702 is closed by the piston 801. When draining water, open the valve 203 and the manhole cover 4, and the water flows out successively through the manhole 3, the installation pipe 1, the upper end pipe 201, the valve 203, and the lower end pipe 202. When flushing, open the valve 203 and start the external fresh water pump. The external fresh water pump pumps the fresh water in the tank and discharges it from the output end to the straight pipe 701. Then, the piston 801 inside the straight pipe 701 is squeezed. After the piston 801 is squeezed, the return spring 803 contracts, and at the same time, the expansion bladder cylinder 1003 is squeezed to expand inward through hydraulic oil transmission, so that the water passage opening 1006 is closed. At the same time, when the piston 801 is squeezed to the right, the elbow pipe 702 opens and is unobstructed with the straight pipe 701, and the water flows into the elbow pipe 702, then enters the diversion cavity 903 inside the diversion barrel 901 from the second side connection end 6, and then sprays out from the flushing port 906, so as to wash down along the pipe wall. The upper part of the diversion barrel 901 is close to the pipe orifice, and it is easy to take into account when manually cleaning the manhole cover 4.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
