JP3026090U - Floating tank for small vessels - Google Patents

Abstract

(57) [Summary] This is a device that enhances the functions of the hull by installing air tanks on both sides of the hull and freely controlling this with hydraulic power. [Purpose] To bring stability to small vessels and keep the bottom of the vessel as clean as possible. [Structure] By attaching an air tank to the existing hull and expanding or lowering it with the force of a hydraulic pump, a stable control can be obtained and the hull can be floated above the water surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is an auxiliary air tank that can be mounted on small vessels to provide stable control without sacrificing conventional safe navigation and keep the bottom of the vessel as clean as possible.

[0002]

[Prior art]

 Currently, the majority of small vessels are lightweight, plastic vessels, so the bottom of the vessel is shallow and the width of the vessel is narrowed to increase speed, so it is currently vulnerable to waves and winds. In addition, leisure boats do not travel frequently, so the moss on the bottom of the boat is less likely to attach, so we often clean and paint the bottom of the boat.

[0003]

[Problems to be solved by the device]

 Therefore, the purpose of this plan is to bring stability to a small plastic ship, and to prevent pollution of the sea by keeping the bottom of a leisure boat, which is often moved, as clean as possible.

[0004]

[Means for Solving the Problems]

 Plastic air tanks (3) on both sides of the hull are attached to an existing small vessel, and they are controlled by a hydraulic pump (2) according to the size of the wave and the application such as fixed vessel. I will.

[0005]

[Action]

 This air tank depends on the size of the ship, but if the size is buoyant enough to reduce the draft by half even at the bottom, the ship width can be increased as shown in Fig. 3. Also, if you use hydraulic force as shown in Fig. 4, you can float the bottom of the ship above the water surface.

[0006]

Example As shown in FIG. 1, a pair of left and right air tanks (3) are attached to an existing boat with hinges (4), and a hydraulic cylinder (1) is adjusted with a hydraulic pump (2). At the position of, the ship is as wide as it is, and you can feel a sense of stability even with a small boat. In addition, the bottom of the ship can be floated above the water surface with one switch of the hydraulic pump (2) as shown in Fig. 4.

[0007]

[Effect of device]

 Since the present invention can be installed on existing small vessels, it can be supplied cheaply. Also, by installing this air tank, the main body can be stabilized even if it is small, and if the bottom of the ship is made large enough, it is not necessary to raise the hull to a dog. This eliminates the trouble of cleaning the bottom of the ship, painting the bottom of the ship, and does not pollute the sea.
