5. The watercraft aft deck and artificial beach of claim 1 wherein: the rear deck plate floats on the sea surface after being adjusted by the position of the mechanical arm, and the time for lowering the rear deck plate is selected from the climate and the position with small sea surface stormy waves and moderate sea water depth for the consideration of building artificial sand beach.

Technical Field

The invention discloses a ship rear cabin plate and an artificial beach, and particularly relates to a multifunctional ship rear cabin plate and a using method of the artificial beach.

Background

With the increasing improvement of living standard of people, the requirement of people on mental enjoyment is higher, so that artificial sand beach can be seen in some parks or tourist attractions to meet the problem that people on the inland cannot enjoy the sand beach due to long distance; artificial sand beach is a garden landscape engineering where people imitate natural sand beach to carry out artificial sand filling on the bank of rivers or lakes and the like.

The advantages of the backstays of large-scale cruise ships and yachts are fully utilized to build an artificial beach system matched with ships, so that people can enjoy the beach which can be played at any time and any place while playing the wind and light in the sea.

Disclosure of Invention

The invention aims to build an artificial beach which can be used for a cruise ship, and the artificial beach with a sand yard and a rear hatch cover and is berthed in still water can be built by mechanically and automatically setting the motion mode of the rear hatch cover plate of the ship and matching with a sand conveying device at the stern.

The invention relates to a ship rear hatch cover, which comprises a power arm system, wherein the power arm system is connected with and controls the rear hatch cover to be lowered and comprises a driving arm and a driven arm, the rear hatch cover and the driven arm are welded and adhered, and a cover plate is horizontally pushed and lowered in a hydraulic traction mode; the rear cabin cover plate is preferably spliced and built by a novel marine building module, and the shell of the rear cabin cover plate is made of environment-friendly rubber.

The tail of the ship is provided with a sand conveying pipe type sand conveying device, the bottom of the sand conveying pipe type sand conveying device is provided with a rotatable base, a sand storage bin is arranged on the sand storage bin, the sand storage bin is connected with a sand conveying pipe through a pipeline opening, a sand pump is arranged in the sand storage bin, the tail end of the sand storage bin is provided with a sand conveying pump, and sand bodies are sprayed out of a sand conveying gun head through the sand conveying pipe and are paved manually to form an artificial sand beach of the rear cabin plate.
