Description

Technical Field

[0001] This invention relates to improvements to watercraft, specifically improvements based on prior application No. 2021102473141. Background Technology

[0002] The prior application (document number 2021102473141) is a technical solution with excellent energy-saving and speed-up effects. However, it has deficiencies in impact resistance.

[0003] This technical solution aims to overcome the shortcomings of the previous application document No. 2021102473141. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior application No. 2021102473141, this document proposes an improvement scheme for the seaplane.

[0005] The technical solution adopted by this invention to solve its technical problem is: (1) A vertically erected anti-collision bar is installed at the bow of the ship, with the foremost line of the anti-collision bar being the foremost line of the pointed end of the bow. Function: Anti-collision.

[0006] (2) The anti-collision bar is divided into upper and lower sections, with the air guide tube of the bow pneumatic device in the middle. Function: In addition to providing power, the bow pneumatic device accelerates the flow of gas in front of the bow, thereby reducing pressure, drag and speed.

[0007] (3) The anti-collision bar and the pointed bow together form a low-pressure area behind the anti-collision bar (the water flow and air flow are split to both sides by the anti-collision bar), reducing water and air resistance.

[0008] (4) Set an upper stern ramp at the stern. The three points for determining the upper stern ramp are: the intersection of the tip of the stern cone and the waterline, and the tangent points of the top semicircle of the stern top and the left and right circles. Function: The convection and collision of gases at the stern will generate high pressure, and setting an upper stern ramp can obtain high pressure assist.

[0009] (5) Set a stern ramp at the stern. The three points for determining the stern ramp are: the intersection of the tip of the stern circle and the waterline, and the tangent points of the bottom semicircle of the stern bottom and the left and right circles. Function: The convection of water at the stern creates high pressure, and the stern ramp can provide high pressure boosting.

[0010] (6) The nozzle is partially or completely exposed above the water surface, and the last line of the rudder inside the nozzle is the last line of the pointed stern. Function: The point of application of power is in the high-pressure zone where water and air collide from side to side. The high pressure at the stern helps with propulsion.

[0011] (7) The water pump suction port is located on the centerline of the ship and in the semi-circular area at the stern. The specific location is determined according to the installation requirements of the power unit. There is a garbage guard at the bottom to prevent garbage and debris from entering.

[0012] (8) The hull drain is located on the ship's centerline, in front of the water pump intake. Function: The drain is located on the centerline, minimizing the impact of lateral swaying. It drains water without allowing water in, ensuring high safety; it also has a draft scale for easy observation of real-time draft by the crew.

[0013] 1. Garbage barrier: Prevents garbage and debris from entering or exiting the cylinder and prevents the check float valve from leaving the cylinder.

[0014] 2. Barrier: It jams the check float valve and blocks the water inlet channel.

[0015] 3. Check valve: The diameter is smaller than the cylinder diameter but larger than the valve opening diameter, and it floats up and down with the water surface; it drains water under normal conditions and blocks the inlet channel in case of emergency.

[0016] 4. Draft markings: Draft markings are marked inside the sump drain pipes at the bottom of the ship, allowing crew members to easily observe the real-time draft depth. Traditional ships have draft markings on the outer wall, making it difficult for crew members to observe the real-time draft depth.

[0017] (9) Fence: Inside the port and starboard walls, there is a top plate to reduce resistance during navigation. The ship's mooring lines are attached to the fence.

[0018] The beneficial effects of this invention are: it utilizes the lateral convection impact energy of the fluid on both sides of the stern, obtained through the upper and lower sloping surfaces of the stern, to achieve power boost, drag reduction, energy saving, consumption reduction, and speed increase; the absence of drain outlets on the hull prevents water ingress even with significant lateral swaying; the bottom drain pipe is located on the centerline, allowing water to drain without ingress; the bottom drain pipe has draft markings for easy observation of real-time draft by the crew; and it offers strong resistance to wind, waves, and lateral swaying. The bow features a bumper bar, enhancing safety. The bumper bar is divided into upper and lower sections, with the middle section serving as a guide tube for the bow pneumatic device; in addition to providing power, the pneumatic device accelerates the airflow in front of the bow, thereby reducing pressure, drag, and speed. The bumper bar, together with the pointed bow, forms a low-pressure zone behind it, reducing water and air resistance. Attached Figure Description
