関する。[Detailed description of the invention] [Field of industrial application] This invention prevents the bottom of a ship such as a yacht or boat from coming into contact with seawater that causes biofouling when it is moored or stored for a long period of time. This invention relates to a ship bottom antifouling cover that can naturally drain accumulated water above the waterline even if seawater or rainwater flows in.

いものである。[Prior Art] The amount of shellfish adhering to the bottom of a ship increases over time. This biofouling causes increased resistance on the ship's hull during travel, impeding the ship's original performance. For example, it results in an increase in the amount of fuel consumed for driving, which is uneconomical. In addition, in order to remove attached organisms, it is necessary to scrape off the attached organisms from the bottom of the ship. Such work is extremely troublesome for ship owners.

れていない。 For example, to prevent a quantitative increase in sessile organisms,
In the case of small vessels such as boats and yachts, the vessels are taken to storage facilities on land during storage. However, the labor and expense required for this lifting and lowering work imposes a considerable burden on ship owners, and the reality is that sufficient facilities for accommodating ships are still not widely available. Therefore, the ship had no choice but to be stored at sea. In order to prevent biofouling during storage at sea, a method of applying antifouling paint or the like to the bottom of the ship has been proposed. However, the antifouling paint has strict legal regulations due to its toxicity.
Moreover, no one that exhibits sufficient performance effects has been developed.
このような問題を解消するものとして、後部が
開閉自在となつているカバーで船底全体を覆うこ
とが、実開昭56−148992号公報で提案されてい

に触れることがないようにしたものである。 To solve this problem, Japanese Utility Model Application Publication No. 148992/1983 proposes to cover the entire bottom of the ship with a cover that can be opened and closed at the rear. This proposal uses a cover to prevent the bottom of the ship from coming into direct contact with seawater.

However, in the case of the one proposed in Japanese Utility Model Application Publication No. 56-148992, there is no mechanism to easily open and close the rear part of the cover, making it difficult to attach the cover to the bottom of the ship. It was something that came with it. Moreover, when the cover is closed, the rear part of the cover does not have any sealing mechanism.
Seawater easily enters the cover during storage. As a result, there was a drawback that the bottom of the ship was not sufficiently protected.

的とする。 Therefore, the present invention is designed to naturally drain accumulated water above the waterline even if seawater or rainwater accumulates between the bottom antifouling cover that covers the entire bottom of the ship and the hull when the ship is stored at sea. Furthermore, the purpose is to ensure the protection of the bottom of the ship by preventing seawater from entering.

体２の主部が構成される。 The cover body 2 of the boat bottom antifouling cover 1 is formed into approximately the same shape as the bottom of the boat A. A frame 3 is attached to the entire periphery or a portion of the cover body 2 at a portion corresponding to the waterline. The frame 3 is preferably made of a hollow tubular material or the like in order to increase the buoyancy of the cover body 2. Further, a portion corresponding to the lower part of the keel of boat A is formed of reinforcing wire or the like. The frame 3 and the reinforcing wire constitute the main part of the cover body 2.

とは言うまでもない。 Furthermore, a rising wall 4 that surrounds the entire lower part of the boat A is formed in the portion of the cover body 2 above the frame 3, that is, in the cover body 2 above the waterline. As shown in FIG. 1, the rising wall 4 is arranged over the entire circumference of the waterline portion with a required spacing between it and the hull. It is preferable to attach an elastic material such as sponge or rubber to the upper edge of this rising wall 4 so as not to damage the wall of the ship when it is attached to the ship. Furthermore, it goes without saying that a similar cushioning material or the like may be provided inside the cover body 2.

る。 Opening/closing portions 4 of a required length are installed in the portions of the rising wall 4 corresponding to as straight a portion as possible on both the port and starboard sides of the boat A.
a is formed. The opening/closing part 4a is constructed by, for example, attaching a curtain-shaped soft material to the frame 3 so as to be openable and closable. Holes are provided at the upper portions of both ends of the opening/closing portion 4a, through which the other end of a string 6, one end of which is tied to a metal fitting 5 on the deck of the boat A, is inserted and tied. The string 6 acts as a control band. Note that when an elastic material (not shown) is used for a part of the operating band, if more than a predetermined amount of seawater, rainwater, etc. accumulates in the space surrounded by the rising wall 4, the elastic pull of the operating band will Since the opening/closing portion 4a is opened by the load of the accumulated water against the tensile force, the accumulated water exceeding the predetermined amount can be automatically discharged.

ち揚げることも防がれる。 By pulling up the string 6, the opening/closing part 4a becomes flush with the rising walls 4 on both sides and constitutes a part of the rising walls 4. On the other hand, by releasing the string 6, the opening/closing part 4a rotates toward the water surface, opening the space inside the rising wall 4 to the outside. When the opening/closing portion 4a is in the open state, the water accumulated in the cover body 2 is discharged. Moreover, when the opening/closing part 4a is kept open when the cover main body 2 is attached, the space defined by the rising wall 4 is prevented from carrying up an excess amount of water unnecessarily.

なうことが可能となる。 A curtain-shaped waterproof sealing member 7 is provided between both side ends of the opening/closing part 4a and the end of the rising wall 4. The waterproof sealing member 7 can waterproof the joint portion that occurs between the rising wall 4 and the opening/closing part 4a when the opening/closing part 4a is closed to form a flush rising wall. As a result, it is possible to prevent seawater from entering from the outside and reliably protect the bottom of the ship.

出来る。 The opening/closing portion 4a does not necessarily need to be provided on both sides, and may be provided at one or more locations at an appropriate position. In addition, regarding the cover structure, the main body of the cover is formed from waterproof cloth, rubber, vinyl, urethane curtains, etc. on the outside, and the frame is raised a certain width above the water surface with the required number of floats and supported by the required number of ropes. By adopting a configuration that is fixed to the ship,
A rising wall is formed. At this time, if the opening/closing part is provided within this range, a simpler structure can be achieved.

れている。 After the cover body 2 is attached to the bottom of the ship, seawater existing between the cover body 2 and the wall of the bottom of the ship is discharged to the outside by a discharge pump 8 attached to the lower part of the cover body 2, if necessary. The discharge pump 8 is of a type that operates using the tidal level difference, and has a structure shown in FIG. 3. That is,
A cylinder 10 with a built-in piston 9 in the center
Inside, there is a pair of bellows 1 toward both ends.
1 and 12 are arranged from the piston 9 toward both ends of the cylinder 10. A required number of check valves 13 are provided on both the left and right sides of the cylinder 10.
Further, the piston 9 is connected to a rope 14, and a main anchor 15 that is placed submerged in the seabed and a small anchor 16 that is suspended in the sea are attached to both ends of the rope 14, respectively. There is.

雨水等が外部に排出される。 When the hull with the cover body 2 equipped with the discharge pump 8 with such a configuration is stored in the state shown in Fig. 2, the distance between the discharge pump 8 and the seabed changes depending on the tidal level difference. do. As this distance changes, the small anchor 16 moves up and down in the sea, and the piston 9 reciprocates within the cylinder 10 via the rope 14 connecting the small anchor 16. Due to this reciprocating movement of the piston 9, seawater flows from inside the cover body 2 through the check valve 13 and into the cylinder 10.
Rainwater, etc. is discharged outside.

つことができる。 In this way, the water accumulated inside the hull and the cover body 2 is sequentially discharged to the outside of the cover body 2 by the discharge pump 8. However, after the cover body 2 is attached to the bottom of the ship, seawater, rainwater, etc. enters the gap between the hull and the cover body 2 due to rain or strong winds and waves, and accumulates, and the accumulated water rises up and forms a wall. It may reach the upper edge of 4. It is necessary to drain the accumulated water in the rising portion where biofouling is particularly severe as soon as possible. In this example,
By opening and closing the opening/closing portion 4a at any time, this portion can be drained quickly. Also, if necessary, install a discharge valve (not shown) near the cover water line.
By providing this, drainage can be carried out more reliably and quickly. In this way, the bottom portion of the ship above the waterline can be quickly prevented from coming into contact with seawater.

り、ボートＡに対する装着が一層容易となる。 In addition, since a part of the rising wall 4 of the bottom antifouling cover 1 has an opening/closing part 4a that can be opened and closed, when sinking with the cover body 2, by opening the opening/closing part 4a, the inside of the bottom antifouling cover 1 can be accessed. Seawater flows in and tends to make the bottom antifouling cover 1 shaped like a water boat. Further, when attaching the bottom antifouling cover 1 to the bottom of the ship, if the opening/closing part 4a is maintained in an open state, water will flow out from the opening/closing part 4a, and the effort required for attachment can be reduced. Further, water does not accumulate in the cover main body 2 above the water line. Furthermore, by closing the opening/closing portion 4a after installation, it is possible to prevent seawater from entering the bottom antifouling cover 1 due to wind and waves. In this case, since the expandable and contractible waterproof sealing member 7 is interposed between both ends of the opening/closing part 4a and the end of the rising wall 4 facing the both ends, the opening/closing part 4a and the rising wall 4 are connected to each other. The seams are sealed to ensure that seawater does not enter. Furthermore, if a suspended ballast and a floating body (not shown) are adjustably set at the rear of the bottom antifouling cover 1 as necessary, the bottom antifouling cover 1 can be sunk diagonally, making attachment to the boat A even easier. becomes.

ることはいうまでもない。 Note that when installing the bottom antifouling cover 1, it is not necessarily necessary to install the discharge pump 8. In other words, even if accumulated water remains in the bottom antifouling cover 1 below the waterline, the outside seawater that causes shellfish adhesion is isolated from the inside of the bottom antifouling cover 1, and the bottom antifouling cover 1 Oxygen is not supplied to the inside of the dirty cover 1 either. Therefore, the inside of the bottom antifouling cover 1 is in an atmosphere in which it is extremely difficult for biological attachment to occur. However, it goes without saying that by attaching the discharge pump 8 to the bottom of the ship and creating an atmosphere in which attached organisms cannot grow on the bottom of the ship, the bottom of the ship can be protected even more reliably.

As explained above, in the boat bottom antifouling cover of the present invention, since the cover body has a shape substantially equal to the bottom of the boat, it can be easily positioned when attached to the boat hull. In addition, since the opening/closing part is provided on the rising wall, the accumulated water in the bottom antifouling cover is quickly discharged when the bottom antifouling cover is installed, making the installation work extremely easy. Since the upright wall is located at a level above the waterline when the bottom of the ship is covered, water is prevented from flowing into the cover even when wind and waves are strong. Further, even after the device is installed, it is possible to discharge accumulated water in the open state and prevent seawater from entering the bottom antifouling cover in the closed state.
As a result, it becomes possible to maintain a good condition free of biofouling for a long period of time.
